Bogoliubov transformation
In theoretical physics, the Bogoliubov transformation, also known as the Bogoliubov–Valatin transformation, was independently developed in 1958 by Nikolay Bogolyubov and John George Valatin for finding solutions of BCS theory in a homogeneous system. The Bogoliubov transformation is an isomorphism of either the canonical commutation relation algebra or canonical anticommutation relation algebra. This induces an autoequivalence on the respective representations. The Bogoliubov transformation is often used to diagonalize Hamiltonians, which yields the stationary solutions of the corresponding Schrödinger equation. The Bogoliubov transformation is also important for understanding the Unruh effect, Hawking radiation, pairing effects in nuclear physics, and many other topics.
The Bogoliubov transformation is often used to diagonalize Hamiltonians, with a corresponding transformation of the state function. Operator eigenvalues calculated with the diagonalized Hamiltonian on the transformed state function thus are the same as before.

Protein crystallization is the process of formation of a regular array of individual protein molecules stabilized by crystal contacts. If the crystal is sufficiently ordered, it will diffract. Some proteins naturally form crystalline arrays, like aquaporin in the lens of the eye.[1]
In the process of protein crystallization, proteins are dissolved in an aqueous environment and sample solution until they reach the supersaturated state.[2] Different methods are used to reach that state such as vapor diffusion, microbatch, microdialysis, and free-interface diffusion. Developing protein crystals is a difficult process influenced by many factors, including pH, temperature, ionic strength in the crystallization solution, and even gravity.[2] Once formed, these crystals can be used in structural biology to study the molecular structure of the protein, particularly for various industrial or medical purposes.[3][4]

The Twelve Spies (Hebrew: שְׁנֵים עָשָׂר הַמְרַגְּלִים), as recorded in the Book of Numbers, were a group of Israelite chieftains, one from each of the Twelve Tribes, who were dispatched by Moses to scout out the Land of Canaan for 40 days[1] as a future home for the Israelite people, during the time when the Israelites were in the wilderness following their Exodus from Ancient Egypt. The account is found in Numbers 13:1–33, and is repeated with some differences in Deuteronomy 1:22–40.
God had promised Abraham that there would be a Promised Land for the nations to come out of his son, Isaac. The land of Canaan which the spies were to explore was the same Promised Land. Moses asked for an assessment of the geographical features of the land, the strength and numbers of the population, the agricultural potential and actual performance of the land, civic organization (whether their cities were like camps or strongholds), and forestry conditions. He also asked them to be positive in their outlook and to return with samples of local produce.
When ten of the twelve spies showed little faith, in the doom and gloom report they gave about the land, they were slandering what they believed God had promised them. They did not believe that God could help them, and the people as a whole were persuaded that it was not possible to take the land. As a result, the entire nation was made to wander in the desert for 40 years, until almost the entire generation of men had died.[2] Joshua and Caleb were the two spies who brought back a good report and believed that God would help them succeed. They were the only men from their generation permitted to go into the Promised Land after the time of wandering.
In the Standard Model List of Particles, there are 12 types of elementary fermions: six quarks and six leptons.
There are six leptons in total; the three charged leptons are called "electron-like leptons", while the neutral leptons are called "neutrinos". Neutrinos are known to oscillate, so that neutrinos of definite flavor do not have definite mass, rather they exist in a superposition of mass eigenstates. The hypothetical heavy right-handed neutrino, called a "sterile neutrino", has been left off the list. The best known of all leptons is the electron.

Module (mathematics)
In mathematics, a module is one of the fundamental algebraic structures used in abstract algebra. A module over a ring is a generalization of the notion of vector space over a field, wherein the corresponding scalars are the elements of an arbitrary given ring (with identity) and a multiplication (on the left and/or on the right) is defined between elements of the ring and elements of the module. A module taking its scalars from a ring R is called an R-module.
Thus, a module, like a vector space, is an additive abelian group; a product is defined between elements of the ring and elements of the module that is distributive over the addition operation of each parameter and is compatible with the ring multiplication.
Modules are very closely related to the representation theory of groups. They are also one of the central notions of commutative algebra and homological algebra, and are used widely in algebraic geometry and algebraic topology.

Pyrimidine
Pyrimidine is an aromatic heterocyclic organic compound similar to pyridine. One of the three diazines (six-membered heterocyclics with two nitrogen atoms in the ring), it has the nitrogen atoms at positions 1 and 3 in the ring.[4]:250 The other diazines are pyrazine (nitrogen atoms at the 1 and 4 positions) and pyridazine (nitrogen atoms at the 1 and 2 positions). In nucleic acids, three types of nucleobases are pyrimidine derivatives: cytosine (C), thymine (T), and uracil (U).Franck–Condon principle

Lattice (order)
A lattice is an abstract structure studied in the mathematical subdisciplines of order theory and abstract algebra. It consists of a partially ordered set in which every two elements have a unique supremum (also called a least upper bound or join) and a unique infimum (also called a greatest lower bound or meet). An example is given by the natural numbers, partially ordered by divisibility, for which the unique supremum is the least common multiple and the unique infimum is the greatest common divisor.
Lattices can also be characterized as algebraic structures satisfying certain axiomatic identities. Since the two definitions are equivalent, lattice theory draws on both order theory and universal algebra. Semilattices include lattices, which in turn include Heyting and Boolean algebras. These "lattice-like" structures all admit order-theoretic as well as algebraic descriptions.

Deferred adjudication
A deferred adjudication, also known in some jurisdictions as an adjournment in contemplation of dismissal (ACOD), probation before judgment (PBJ), or deferred entry of judgment (DEJ), is a form of plea deal available in various jurisdictions, where a defendant pleads "guilty" or "no contest" to criminal charges in exchange for meeting certain requirements laid out by the court within an allotted period of time also ordered by the court. Upon completion of the requirements, which may include probation, treatment, community service, some form of community supervision, or some other diversion program, the defendant may avoid a formal conviction on their record or have their case dismissed.[1][2] In some cases, an order of non-disclosure can be obtained, and sometimes a record can be expunged.Do Mirror Neurons Give Us Empathy?

What Is a Promoter?
A stock promoter is an individual or organization that helps raise money for some type of investment activity. Stock promoters may raise money for a company by offering investment vehicles other than traditional stocks and bonds, such as limited partnerships and direct investment activities. Often, promoters are paid in company stock or a percentage of the capital raised.

Three-sector model
The three-sector model in economics divides economies into three sectors of activity: extraction of raw materials (primary), manufacturing (secondary), and services (tertiary).[1]
According to the model, the main focus of an economy's activity
shifts from the primary, through the secondary and finally to the
tertiary sector. Countries with a low per capita income are in an early state of development; the main part of their national income is achieved through production in the primary sector. Countries in a more advanced state of development, with a medium national income,
generate their income mostly in the secondary sector. In highly
developed countries with a high income, the tertiary sector dominates
the total output of the economy. The model was developed by Allan Fisher,[2][3][4] Colin Clark,[5] and Jean Fourastié.[6]
Support vector machine
In machine learning, support-vector machines (SVMs, also support-vector networks[1]) are supervised learning models with associated learning algorithms that analyze data used for classification and regression analysis. Developed at AT&T Bell Laboratories by Vapnik with colleagues (Boser et al., 1992, Guyon et al., 1993, Vapnik et al., 1997), it presents one of the most robust prediction methods, based on the statistical learning framework or VC theory proposed by Vapnik and Chervonenkis (1974) and Vapnik (1982, 1995). Given a set of training examples, each marked as belonging to one or the other of two categories, an SVM training algorithm builds a model that assigns new examples to one category or the other, making it a non-probabilistic binary linear classifier (although methods such as Platt scaling exist to use SVM in a probabilistic classification setting). An SVM model is a representation of the examples as points in space, mapped so that the examples of the separate categories are divided by a clear gap that is as wide as possible. New examples are then mapped into that same space and predicted to belong to a category based on the side of the gap on which they fall.
In addition to performing linear classification, SVMs can efficiently perform a non-linear classification using what is called the kernel trick, implicitly mapping their inputs into high-dimensional feature spaces.
When data are unlabelled, supervised learning is not possible, and an unsupervised learning approach is required, which attempts to find natural clustering of the data to groups, and then map new data to these formed groups. The support-vector clustering[2] algorithm, created by Hava Siegelmann and Vladimir Vapnik, applies the statistics of support vectors, developed in the support vector machines algorithm, to categorize unlabeled data, and is one of the most widely used clustering algorithms in industrial applications.

Event stream processing, or ESP, is a set of technologies designed to assist the construction of event-driven information systems. ESP technologies include event visualization, event databases, event-driven middleware, and event processing languages, or complex event processing (CEP). In practice, the terms ESP and CEP are often used interchangeably. ESP deals with the task of processing streams of event data with the goal of identifying the meaningful pattern within those streams, employing techniques such as detection of relationships between multiple events, event correlation, event hierarchies, and other aspects such as causality, membership and timing.
ESP enables many different applications such as algorithmic trading in financial services, radio-frequency identification (RFID) event processing applications, fraud detection, process monitoring, and location-based services in telecommunications.

Lp space
In mathematics, the Lp spaces are function spaces defined using a natural generalization of the p-norm for finite-dimensional vector spaces. They are sometimes called Lebesgue spaces, named after Henri Lebesgue (Dunford & Schwartz 1958, III.3), although according to the Bourbaki group (Bourbaki 1987) they were first introduced by Frigyes Riesz (Riesz 1910). Lp spaces form an important class of Banach spaces in functional analysis, and of topological vector spaces. Because of their key role in the mathematical analysis of measure and probability spaces, Lebesgue spaces are used also in the theoretical discussion of problems in physics, statistics, finance, engineering, and other disciplines.Topological vector space
In mathematics, a topological vector space (also called a linear topological space and commonly abbreviated TVS or t.v.s.) is one of the basic structures investigated in functional analysis.
A topological vector space is a vector space (an algebraic structure) which is also a topological space, the latter thereby admitting a notion of continuity. More specifically, its topological space has a uniform topological structure, allowing a notion of uniform convergence.
The elements of topological vector spaces are typically functions or linear operators acting on topological vector spaces, and the topology is often defined so as to capture a particular notion of convergence of sequences of functions.
Banach spaces and Hilbert spaces, are well-known examples.
Unless stated otherwise, the underlying field of a topological vector space is assumed to be either the complex numbers ℂ or the real numbers ℝ.
Nicolas Bourbaki (French pronunciation: [nikɔla buʁbaki]) is the collective pseudonym of a group of mathematicians, predominantly French alumni of the École normale supérieure (ENS). Founded in 1934–1935, the Bourbaki group originally intended to prepare a new textbook in analysis. Over time the project became much more ambitious, growing into a large series of textbooks published under the Bourbaki name, meant to treat modern pure mathematics. The series is known collectively as the Éléments de mathématique (Elements of Mathematics), the group's central work. Topics treated in the series include set theory, abstract algebra, topology, analysis, Lie groups and Lie algebras.
Bourbaki was founded in response to the effects of the First World War which caused the death of a generation of French mathematicians; as a result, young university instructors were forced to use dated texts. While teaching at the University of Strasbourg, Henri Cartan complained to his colleague André Weil of the inadequacy of available course material, which prompted Weil to propose a meeting with others in Paris to collectively write a modern analysis textbook. The group's core founders were Cartan, Claude Chevalley, Jean Delsarte, Jean Dieudonné and Weil; others participated briefly during the group's early years, and membership has changed gradually over time. Although former members openly discuss their past involvement with the group, Bourbaki has a custom of keeping its current membership secret.
The group's namesake derives from the 19th century French general Charles-Denis Bourbaki,[3] who had a career of successful military campaigns before suffering a dramatic loss in the Franco-Prussian War. The name was therefore familiar to early 20th century French students. Weil remembered an ENS student prank in which an upperclassman posed as a professor and presented a "theorem of Bourbaki"; the name was later adopted.
The Bourbaki group holds regular private conferences for the purpose of drafting and expanding the Éléments. Topics are assigned to subcommittees, drafts are debated, and unanimous agreement is required before a text is deemed fit for publication. Although slow and labor-intensive, the process results in a work which meets the group's standards for rigour and generality. The group is also associated with the Séminaire Bourbaki, a regular series of lectures presented by members and non-members of the group, also published and disseminated as written documents. Bourbaki maintains an office at the ENS.[4]
Nicolas Bourbaki was influential in 20th century mathematics, particularly during the middle of the century when volumes of the Éléments appeared frequently. The group is noted among mathematicians for its rigorous presentation and for introducing the notion of a mathematical structure, an idea related to the broader, interdisciplinary concept of structuralism.[5][6][7] Bourbaki's work informed the New Math, a trend in elementary math education during the 1960s. Although the group remains active, its influence is considered to have declined due to infrequent publication of new volumes of the Éléments. However the collective's most recent publication appeared in 2016, treating algebraic topology.

In physics, a phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, specifically in solids and some liquids.
Bohr radius
Rydberg constant
Quasiparticle
In physics, quasiparticles and collective excitations (which are closely related) are emergent phenomena that occur when a microscopically complicated system such as a solid behaves as if it contained different weakly interacting particles in vacuum. For example, as an electron travels through a semiconductor, its motion is disturbed in a complex way by its interactions with other electrons and with atomic nuclei. The electron behaves as though it has a different effective mass travelling unperturbed in vacuum. Such an electron is called an electron quasiparticle In another example, the aggregate motion of electrons in the valence band of a semiconductor or a hole band in a metal behave as though the material instead contained positively charged quasiparticles called electron holes. Other quasiparticles or collective excitations include the phonon (a particle derived from the vibrations of atoms in a solid), the plasmons (a particle derived from plasma oscillation), and many others.
These particles are typically called quasiparticles if they are related to fermions, and called collective excitations if they are related to bosons, although the precise distinction is not universally agreed upon. Thus, electrons and electron holes (fermions) are typically called quasiparticles, while phonons and plasmons (baryons) are typically called collective excitations.
The quasiparticle concept is important in condensed matter physics because it can simplify the many-body problem in quantum mechanics.

Aramid fibers are a class of heat-resistant and strong synthetic fibers. They are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in marine cordage, marine hull reinforcement, and as an asbestos substitute.[1] The name is a portmanteau of "aromatic polyamide".
The chain molecules in the fibers are highly oriented along the fiber axis. As a result, a higher proportion of the chemical bond contributes more to fiber strength than in many other synthetic fibers. Aramides have a very high melting point (>500 °C).
Common aramid brand names include Kevlar, Nomex, and Twaron.

The Serial Peripheral Interface (SPI) is a synchronous serial communication interface specification used for short-distance communication, primarily in embedded systems. The interface was developed by Motorola in the mid-1980s and has become a de facto standard. Typical applications include Secure Digital cards and liquid crystal displays.
SPI devices communicate in full duplex mode using a master-slave architecture (alternate terminology being main and secondary) with a single master. The master device originates the frame for reading and writing. Multiple slave-devices are supported through selection with individual slave select (SS), sometimes called chip select (CS), lines.
Sometimes SPI is called a four-wire serial bus, contrasting with three-, two-, and one-wire serial buses. The SPI may be accurately described as a synchronous serial interface,[1] but it is different from the Synchronous Serial Interface (SSI) protocol, which is also a four-wire synchronous serial communication protocol. The SSI protocol employs differential signaling and provides only a single simplex communication channel. SPI is one master and multi slave communication.

Node of Ranvier
Nodes of Ranvier (/ˌrɑːnviˈeɪ/ RAHN-vee-AY, /ˈrɑːnvieɪ/ -ay), also known as myelin-sheath gaps, occur along a myelinated axon where the axolemma is exposed to the extracellular space. Nodes of Ranvier are uninsulated and highly enriched in ion channels, allowing them to participate in the exchange of ions required to regenerate the action potential. Nerve conduction in myelinated axons is referred to as saltatory conduction (from the Latin saltare "to hop or to leap") due to the manner in which the action potential seems to "jump" from one node to the next along the axon. This results in faster conduction of the action potential.Radical (chemistry)
An axon (from Greek ἄξων áxōn, axis), or nerve fiber (or nerve fibre: see spelling differences), is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body. The function of the axon is to transmit information to different neurons, muscles, and glands. In certain sensory neurons (pseudounipolar neurons), such as those for touch and warmth, the axons are called afferent nerve fibers and the electrical impulse travels along these from the periphery to the cell body, and from the cell body to the spinal cord along another branch of the same axon. Axon dysfunction has caused many inherited and acquired neurological disorders which can affect both the peripheral and central neurons. Nerve fibers are classed into three types – group A nerve fibers, group B nerve fibers, and group C nerve fibers. Groups A and B are myelinated, and group C are unmyelinated. These groups include both sensory fibers and motor fibers. Another classification groups only the sensory fibers as Type I, Type II, Type III, and Type IV.
Flip (mathematics)
In algebraic geometry, flips and flops are codimension-2 surgery operations arising in the minimal model program, given by blowing up along a relative canonical ring. In dimension 3 flips are used to construct minimal models, and any two birationally equivalent minimal models are connected by a sequence of flops. It is conjectured that the same is true in higher dimensions.

Supersymmetry
In supersymmetric theories the axion has both a scalar and a fermionic superpartner. The fermionic superpartner of the axion is called the axino, the scalar superpartner is called the saxion or dilaton. They are all bundled up in a chiral superfield.
The axino has been predicted to be the lightest supersymmetric particle in such a model. In part due to this property, it is considered a candidate for dark matter.

Activity-regulated cytoskeleton-associated protein is a plasticity protein that in humans is encoded by the ARC gene. It was first characterized in 1995.[5][6] ARC is a member of the immediate-early gene (IEG) family, a rapidly activated class of genes functionally defined by their ability to be transcribed in the presence of protein synthesis inhibitors. ARC mRNA is localized to activated synaptic sites in an NMDA receptor-dependent manner,[7][8] where the newly translated protein is believed to play a critical role in learning and memory-related molecular processes.[9]
Arc protein is widely considered to be important in neurobiology
because of its activity regulation, localization, and utility as a
marker for plastic changes in the brain. Dysfunction in the production
of Arc protein has been implicated as an important factor in
understanding various neurological conditions, including amnesia,[10] Alzheimer's disease, Autism spectrum disorders, and Fragile X syndrome.[11] Along with other IEGs such as ZNF268 and HOMER1, ARC is also a significant tool for systems neuroscience as illustrated by the development of the cellular compartment analysis of temporal activity by fluorescence in situ hybridization, or catFISH technique[12][13] (see fluorescent in situ hybridization).

4 Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5 It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 6 Love does not delight in evil but rejoices with the truth. 7 It always protects, always trusts, always hopes, always perseveres.
8 Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away.| Rely on Marktek Inc. for all your special materials needs related to EMI shielding & suppression, static dissipation, microwave and radar absorbing, resistive heating, sensors, antimicrobial textiles .... and much more! |

Christianity in Ethiopia
Christianity in Ethiopia is the largest religion in the country and dates back to the ancient Kingdom of Aksum, when the King Ezana first adopted the faith. This makes Ethiopia one the first regions in the world to officially adopt Christianity. Various Christian denominations are now followed in the country. Of these, the largest and oldest is the Ethiopian Orthodox Tewahedo Church (in Amharic: የኢትዮጵያ ኦርቶዶክስ ተዋሕዶ ቤተክርስትያን Yäityop'ya ortodoks täwahedo bétäkrestyan) an Oriental Orthodox church centered in Ethiopia. The Orthodox Tewahedo Church was part of the Coptic Orthodox Church until 1959, when it was granted its own patriarch by Coptic Orthodox Pope of Alexandria and Patriarch of All Africa Cyril VI. Ethiopia was the only region of Africa to survive the expansion of Islam as a Christian state.[1]Kwanzaa

Spin chemistry
The Radical-Pair Mechanism (Spin city!)
Spin Chemistry is a sub-field of chemistry and physics, positioned at the intersection of chemical kinetics, photochemistry, magnetic resonance and free radical chemistry, and dealing with magnetic and spin effects in chemical reactions. The examples of phenomena that Spin Chemistry deals with are Chemically Induced Dynamic Nuclear and Electron Polarization (CIDNP and CIDEP), magnetic isotope effects in chemical reactions, as well as the environmental, health effects of static and oscillating electromagnetic fields, and avian magnetoreception, particularly as radical-pair reaction kinetics are dependent on the direction of magnetic fields.[1]

Brownian motor
Brownian motors are nanoscale or molecular machines that use chemical reactions to generate directed motion in space.[1] The theory behind Brownian motors relies on the phenomena of Brownian motion, random motion of particles suspended in a fluid (a liquid or a gas) resulting from their collision with the fast-moving molecules in the fluid.[2]
On the nanoscale (1-100 nm), viscosity dominates inertia, and the extremely high degree of thermal noise in the environment makes conventional directed motion all but impossible, because the forces impelling these motors in the desired direction are minuscule when compared to the random forces exerted by the environment. Brownian motors operate specifically to utilise this high level of random noise to achieve directed motion, and as such are only viable on the nanoscale.[3]
The concept of Brownian motors is a recent one, having only been coined in 1995 by Peter Hänggi, but the existence of such motors in nature may have existed for a very long time and help to explain crucial cellular processes that require movement at the nanoscale, such as protein synthesis and muscular contraction. If this is the case, Brownian motors may have implications for the foundations of life itself.[3]
In more recent times, humans have attempted to apply this knowledge of natural Brownian motors to solve human problems. The applications of Brownian motors are most obvious in nanorobotics due to its inherent reliance on directed motion.[4][5]

8-N-1
8-N-1 is a common shorthand notation for a serial port parameter setting or configuration in asynchronous mode, in which there is one start bit, eight (8) data bits, no (N) parity bit, and one (1) stop bit.[1] As such, 8-N-1 is the most common configuration for PC serial communications today.
The abbreviation is usually given together with the line speed in bits per second, as in 9600/8-N-1. The speed includes bits for framing (stop bits, parity, etc.) and the effective data rate is lower than the bit transmission rate. For 8-N-1 encoding, only 80% of the bits are available for data (for every eight bits of data, ten bits are sent over the serial link — one start bit, the eight data bits, and the one stop bit). This mode was also commonplace for the link between modems until the 1990s when Link Access Procedure for Modems (LAPM) became widespread. 8-N-1 continued in use for the computer to modem connection.[1]

The Beckman Institute for Advanced Science and Technology is a unit of the University of Illinois at Urbana–Champaign dedicated to interdisciplinary research.Beckman Institute for Advanced Science and Technology
The Beckman Institute for Advanced Science and Technology is a unit of the University of Illinois at Urbana–Champaign dedicated to interdisciplinary research. A gift from scientist, businessman, and philanthropist Arnold O. Beckman (1900–2004) and his wife Mabel (1900–1989) led to the building of the Institute which opened in 1989. It is one of five institutions which receive support from the Arnold and Mabel Beckman Foundation on an ongoing basis. Current research at Beckman involves the areas of molecular engineering, intelligent systems, and imaging science. Researchers in these areas work across traditional academic boundaries in scientific projects that can lead to the development of real-world applications in medicine, industry, electronics, and human health across the lifespan.Systems theory is the interdisciplinary study of systems. A system is a cohesive conglomeration of interrelated and interdependent parts which can be natural or human-made. Every system is bounded by space and time, influenced by its environment, defined by its structure and purpose, and expressed through its functioning. A system may be more than the sum of its parts if it expresses synergy or emergent behavior.
Changing one part of a system may affect other parts or the whole system. It may be possible to predict these changes in patterns of behavior. For systems that learn and adapt, the growth and the degree of adaptation depend upon how well the system is engaged with its environment. Some systems support other systems, maintaining the other system to prevent failure. The goals of systems theory are to model a system's dynamics, constraints, conditions, and to elucidate principles (such as purpose, measure, methods, tools) that can be discerned and applied to other systems at every level of nesting, and in a wide range of fields for achieving optimized equifinality.
General systems theory is about developing broadly applicable concepts and principles, as opposed to concepts and principles specific to one domain of knowledge. It distinguishes dynamic or active systems from static or passive systems. Active systems are activity structures or components that interact in behaviours and processes. Passive systems are structures and components that are being processed. For example, a program is passive when it is a disc file and active when it runs in memory. The field is related to systems thinking, machine logic, and systems engineering.

Emotional intelligence (EI), emotional leadership (EL), emotional quotient (EQ) and emotional intelligence quotient (EIQ), is the capability of individuals to recognize their own emotions and those of others, discern between different feelings and label them appropriately, use emotional information to guide thinking and behavior, and manage and/or adjust emotions to adapt to environments or achieve one's goal(s).[1][2] Although the term first appeared in 1964,[3] it gained popularity in the 1995 book Emotional Intelligence, written by the science journalist Daniel Goleman.[4]
Empathy is typically associated with EI, because it relates to an individual connecting their personal experiences with those of others. However, several models exist that aim to measure levels of (empathy) EI. There are currently several models of EI. Goleman's original model may now be considered a mixed model that combines what has since been modeled separately as ability EI and trait EI. Goleman defined EI as the array of skills and characteristics that drive leadership performance.[5] The trait model was developed by Konstantinos V. Petrides in 2001. It "encompasses behavioral dispositions and self perceived abilities and is measured through self report".[6] The ability model, developed by Peter Salovey and John Mayer in 2004, focuses on the individual's ability to process emotional information and use it to navigate the social environment.[7]
Studies have shown that people with high EI have greater mental health, job performance, and leadership skills although no causal relationships have been shown and such findings are likely to be attributable to general intelligence and specific personality traits rather than emotional intelligence as a construct. For example, Goleman indicated that EI accounted for 67% of the abilities deemed necessary for superior performance in leaders, and mattered twice as much as technical expertise or IQ.[8] Other research finds that the effect of EI markers on leadership and managerial performance is non-significant when ability and personality are controlled for,[9] and that general intelligence correlates very closely with leadership.[10] Markers of EI and methods of developing it have become more widely coveted in the past decade by individuals seeking to become more effective leaders. In addition, studies have begun to provide evidence to help characterize the neural mechanisms of emotional intelligence.[11][12][13][14]
Criticisms have centered on whether EI is a real intelligence and whether it has incremental validity over IQ and the Big Five personality traits.[15]

Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, Bombyx mori (the caterpillar of the domestic silkmoth) is the most widely used and intensively studied silkworm. Silk was believed to have first been produced in China as early as the Neolithic Period. Sericulture has become an important cottage industry in countries such as Brazil, China, France, India, Italy, Japan, Korea, and Russia. Today, China and India are the two main producers, with more than 60% of the world's annual production.

Positron emission or beta plus decay (β+ decay) is a subtype of radioactive decay called beta decay, in which a proton inside a radionuclide nucleus is converted into a neutron while releasing a positron and an electron neutrino (νe).[1] Positron emission is mediated by the weak force. The positron is a type of beta particle (β+), the other beta particle being the electron (β−) emitted from the β− decay of a nucleus.
An example of positron emission (β+ decay) is shown with magnesium-23 decaying into sodium-23:

Potassium-40 (40K) is a radioactive isotope of potassium which has a long half-life of 1.251×109 years. It makes up 0.012% (120 ppm) of the total amount of potassium found in nature.
Potassium-40 is a rare example of an isotope that undergoes both types of beta decay. In about 89.28% of events, it decays to calcium-40 (40Ca) with emission of a beta particle (β−, an electron) with a maximum energy of 1.31 MeV and an antineutrino. In about 10.72% of events, it decays to argon-40 (40Ar) by electron capture (EC), with the emission of a neutrino and then a 1.460 MeV gamma ray.[1] The radioactive decay of this particular isotope explains the large abundance of argon (nearly 1%) in the Earth's atmosphere, as well as prevalence of 40Ar over other isotopes. Very rarely (0.001% of events), it will decay to 40Ar by emitting a positron (β+) and a neutrino.[2]
Sodium-22
Sodium-22 is a man-made isotope with a half-life of 2.6 years. It decays emitting a positron (β+ decay) into stable neon-22. A very small part (0.06 %) of the decays leads directly to the ground state of neon. The rest leads to an excited state of neon, partly via electron capture (9.5 %) from the inner atomic shell, but mainly via positron emission. The excited neon state passes into the ground state whereby a 1275 keV γ quantum is emitted. The lifetime of this excited neon is only 3.7 ps.
The emitted positrons react with the electrons of the surrounding matter and lead to a characteristic annihilation radiation at 511 keV. Because of momentum conservation two γ quanta are produced in the pair annihilation of a positron and an electron. These photons are emitted in opposite directions.
As the time delay between the 1275 keV line and the annihilation radiation is unresolvably small, there appears also a line at 1275 + 511 = 1786 keV as a result of simultaneous absorption of both γ quanta.

An onium (plural: onia) is a bound state of a particle and its antiparticle.[1] They are usually named by adding the suffix -onium to the name of the constituting particle except for muonium which, despite its name, is not a bound muon–antimuon onium, but an electron–antimuon bound state, and whose name was assigned by IUPAC. A muon–antimuon onium is called true muonium.Positron emission

Collective bargaining is a process of negotiation between employers and a group of employees aimed at agreements to regulate working salaries, working conditions, benefits, and other aspects of workers' compensation and rights for workers. The interests of the employees are commonly presented by representatives of a trade union to which the employees belong. The collective agreements reached by these negotiations usually set out wage scales, working hours, training, health and safety, overtime, grievance mechanisms, and rights to participate in workplace or company affairs.[1]
The union may negotiate with a single employer (who is typically representing a company's shareholders) or may negotiate with a group of businesses, depending on the country, to reach an industry-wide agreement. A collective agreement functions as a labour contract between an employer and one or more unions. Collective bargaining consists of the process of negotiation between representatives of a union and employers (generally represented by management, or, in some countries such as Austria, Sweden and the Netherlands, by an employers' organization) in respect of the terms and conditions of employment of employees, such as wages, hours of work, working conditions, grievance procedures, and about the rights and responsibilities of trade unions. The parties often refer to the result of the negotiation as a collective bargaining agreement (CBA) or as a collective employment agreement (CEA).
Collective unconscious
Collective unconscious (German: kollektives Unbewusstes) refers to structures of the unconscious mind which are shared among beings of the same species. It is a term coined by Carl Jung. According to Jung, the human collective unconscious is populated by instincts, as well as by archetypes: universal symbols such as The Great Mother, the Wise Old Man, the Shadow, the Tower, Water, and the Tree of Life.[1] Jung considered the collective unconscious to underpin and surround the unconscious mind, distinguishing it from the personal unconscious of Freudian psychoanalysis. He argued that the collective unconscious had profound influence on the lives of individuals, who lived out its symbols and clothed them in meaning through their experiences. The psychotherapeutic practice of analytical psychology revolves around examining the patient's relationship to the collective unconscious.Laurie Anderson: We have to Imagine Different ways to Describe the Ends of Things

A Lone Pair Hairy Ball Theorem...
Lone pair
The hairy ball theorem of algebraic topology (sometimes called the hedgehog theorem in Europe)[1] states that there is no nonvanishing continuous tangent vector field on even-dimensional n-spheres.[2][3] For the ordinary sphere, or 2‑sphere, if f is a continuous function that assigns a vector in R3 to every point p on a sphere such that f(p) is always tangent to the sphere at p, then there is at least one pole, a point where the field vanishes (a p such that f(p) = 0).
The theorem was first proved by Henri Poincaré for the 2-sphere in 1885,[4] and extended to higher dimensions in 1912 by Luitzen Egbertus Jan Brouwer.[5]
The theorem has been expressed colloquially as "you can't comb a hairy ball flat without creating a cowlick" or "you can't comb the hair on a coconut".[6]
A hairy doughnut (2-torus), on the other hand, is quite easily combable. For example,

In mathematics, specifically in algebraic geometry, the fiber product of schemes is a fundamental construction. It has many interpretations and special cases. For example, the fiber product describes how an algebraic variety over one field determines a variety over a bigger field, or the pullback of a family of varieties, or a fiber of a family of varieties. Base change is a closely related notion.Fiber Lasers Mean Ray Guns Are Coming

Quantum error correction
In quantum mechanics and quantum field theory, a Schrödinger field, named after Erwin Schrödinger, is a quantum field which obeys the Schrödinger equation.[1] While any situation described by a Schrödinger field can also be described by a many-body Schrödinger equation for identical particles, the field theory is more suitable for situations where the particle number changes.
A Schrödinger field is also the classical limit of a quantum Schrödinger field, a classical wave which satisfies the Schrödinger equation. Unlike the quantum mechanical wavefunction, if there are interactions between the particles the equation will be nonlinear. These nonlinear equations describe the classical wave limit of a system of interacting identical particles.
The path integral of a Schrödinger field is also known as a coherent state path integral, because the field itself is an annihilation operator whose eigenstates can be thought of as coherent states of the harmonic oscillations of the field modes.
Schrödinger fields are useful for describing Bose–Einstein condensation, the Bogolyubov–de Gennes equation of superconductivity, superfluidity, and many-body theory in general. They are also a useful alternative formalism for nonrelativistic quantum mechanics.
A Schrödinger field is the nonrelativistic limit of a Klein–Gordon field.

Aramid
Aramid fibers are a class of heat-resistant and strong synthetic fibers. They are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in marine cordage, marine hull reinforcement, and as an asbestos substitute. The name is a portmanteau of "aromatic polyamide".
The chain molecules in the fibers are highly oriented along the fiber axis. As a result, a higher proportion of the chemical bond contributes more to fiber strength than in many other synthetic fibers. Aramides have a very high melting point (>500 °C).
Common aramid brand names include Kevlar, Nomex, and Twaron.
