It is a form of learning in which an aversive stimulus (e.Conditioned place preference: Conditioned place preference (CPP) is a form of Pavlovian conditioning used to measure the motivational effects of objects or experiences. This paradigm can also be used to measure conditioned place aversion with an identical procedure involving aversive stimuli instead.Cell envelope antibiotic: A cell envelope antibiotic is an antibacterial that acts primarily at the level of the cell envelope.Large ornamented Ediacaran microfossil: Large ornamented Ediacaran microfossils (LOEMs) are microscopic acritarchs, usually over 100 μm in diameter, which are common in sediments of the Ediacaran period, . They largely disappear from the Ediacaran fossil record before , roughly coeval with the origin of the Ediacara biota.Caninia (genus)Electroshock (wrestler)Statistical relational learning: Statistical relational learning (SRL) is a subdiscipline of artificial intelligence and machine learning that is concerned with domain models that exhibit both uncertainty (which can be dealt with using statistical methods) and complex, relational structure. Typically, the knowledge representation formalisms developed in SRL use (a subset of) first-order logic to describe relational properties of a domain in a general manner (universal quantification) and draw upon probabilistic graphical models (such as Bayesian networks or Markov networks) to model the uncertainty; some also build upon the methods of inductive logic programming.Matrix population models: Population models are used in population ecology to model the dynamics of wildlife or human populations.

People use explicit memory throughout the day, such as remembering the time of an appointment or recollecting an event from years ago.Cocaine intoxicationTimeline of historic inventionsExercise addiction: An exercise addiction can have harmful consequences although it is not listed as a disorder in the latest revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). This type of addiction can be classified under a behavioral addiction in which a person’s behavior becomes obsessive, compulsive, and/or causes dysfunction in a person's life.Threshold host density: Threshold host density (NT), in the context of wildlife disease ecology, refers to the concentration of a population of a particular organism as it relates to disease. Specifically, the threshold host density (NT) of a species refers to the minimum concentration of individuals necessary to sustain a given disease within a population.Bird trapping: Bird trapping techniques to capture wild birds include a wide range of techniques that have their origins in the hunting of birds for food. While hunting for food does not require birds to be caught alive, some trapping techniques capture birds without harming them and are of use in ornithology research.Health geography: Health geography is the application of geographical information, perspectives, and methods to the study of health, disease, and health care.SonepiprazoleAppropriation (By Any Other Name): June 13, 2005Dopamine reuptake inhibitor: A dopamine reuptake inhibitor (DRI) is a type of drug which acts as a reuptake inhibitor of the monoamine neurotransmitter dopamine by blocking the action of the dopamine transporter (DAT). Reuptake inhibition is achieved when extracellular dopamine not absorbed by the postsynaptic neuron is blocked from re-entering the presynaptic neuron.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingSpaced retrieval: Spaced retrieval, also known as expanded retrieval or uniform retrieval, is a learning technique, which requires users to rehearse information to be learned at different and increasing spaced intervals of time or a set uniform amount of time.Haslam, C.Bodega Marine Reserve: Bodega Marine Reserve is a nature reserve and marine reserve on the coast of northern California, located in the vicinity of the Bodega Marine Laboratory on Bodega Head. It is a unit of the University of California Natural Reserve System, that is administered by the University of California, Davis.List of largest volcanic eruptions: In a volcanic eruption, lava, tephra (volcanic bombs, lapilli, and ash), and various gases are expelled from a volcanic vent or fissure. While many eruptions only pose dangers to the immediately surrounding area, Earth's largest eruptions can have a major regional or even global impact, with some affecting the climate and contributing to mass extinctions.DesogestrelMark IV AmphibianEvolution in Variable EnvironmentBranching order of bacterial phyla (Gupta, 2001): There are several models of the Branching order of bacterial phyla, one of these was proposed in 2001 by Gupta based on conserved indels or protein, termed "protein signatures", an alternative approach to molecular phylogeny. Some problematic exceptions and conflicts are present to these conserved indels, however, they are in agreement with several groupings of classes and phyla.Index of geology articles: This is a list of all articles related to geology that cannot be readily placed on the following subtopic pages:List of geological phenomena: A geological phenomenon is a phenomenon which is explained by or sheds light on the science of geology.ChytridiomycotaClimate change in the United Kingdom: Climate change in the United Kingdom has been a subject of protests and controversies, and various policies have been developed to mitigate its effects. It is estimated to demand at least 80-85% emission reductions in the EU during 2008-2050 with reductions as soon as technically possible.Carneau: The Carneau is a breed of pigeon developed over many years of selective breeding primarily as a utility breed. Carneau, along with other varieties of domesticated pigeons, are all descendants from the rock pigeon (Columba livia).Microbial food web: The microbial food web refers the combined trophic interactions among microbes in aquatic environments. These microbes include viruses, bacteria, algae, heterotrophic protists (such as ciliates and flagellates).Septum (cephalopod)RhodolithMatrix model: == Mathematics and physics ==East Sussex Cricket Ground: East Sussex Cricket Ground was a cricket ground in St Leonards-on-Sea, Sussex. The ground was located at the site of a racecourse which had moved after 1826 from the Bulverhythe Salts.Interoceptive exposure: Interoceptive exposure is a cognitive behavioral therapy technique used in the treatment of panic disorder. It refers to carrying out exercises that bring about the physical sensations of a panic attack, such as hyperventilation and high muscle tension, and in the process removing the patient's conditioned response that the physical sensations will cause an attack to happen.TuataraBrachiopodCibicides: Cibicides is a cosmopolitan genus of benthic foraminifera known from at least as far back as the Paleocene (Loeblich & Tappan, 1988) that extends down to the present.Reward system: The reward system is a group of neural structures that are critically involved in mediating the effects of reinforcement. A reward is an appetitive stimulus given to a human or some other animal to alter its behavior.Hadley Centre for Climate Prediction and Research: 140px|rightAnisomycinVegetarian cuisine: Vegetarian cuisine is based on food that meets vegetarian standards by not including meat and animal tissue products (such as gelatin or animal derived rennet). For lacto-ovo vegetarianism (the most common type of vegetarianism in the Western world), eggs and dairy products such as milk and cheese are permitted.Synaptic gating: Synaptic gating is the ability of neural circuits to gate inputs by either suppressing or facilitating specific synaptic activity. Selective inhibition of certain synapses has been studied thoroughly (see Gate theory of pain), and recent studies have supported the existence of permissively gated synaptic transmission.Computational archaeology: Computational archaeology describes computer-based analytical methods for the study of long-term human behaviour and behavioural evolution. As with other sub-disciplines that have prefixed 'computational' to their name (e.Hemispatial neglectIntraguild predation: Intraguild predation, or IGP, is the killing and eating of potential competitors. This interaction represents a combination of predation and competition, because both species rely on the same prey resources and also benefit from preying upon one another.Peat swamp forest: Peat swamp forests are tropical moist forests where waterlogged soil prevents dead leaves and wood from fully decomposing. Over time, this creates a thick layer of acidic peat.Genetic load: Genetic load is the difference between the fitness of the theoretically optimal genotype and the fitness of the observed average genotype in a population. This means that populations with a low genetic load will tend to be healthier, have fitness that is less dispersed, and have offspring that are more likely to survive to reproduction.Interstimulus interval: The interstimulus interval (often abbreviated as ISI) is the temporal interval between the offset of one stimulus to the onset of another. For instance, Max Wertheimer did experiments with two stationary, flashing lights that at some interstimulus intervals appeared to the subject as moving instead of stationary.Doob decomposition theorem: In the theory of stochastic processes in discrete time, a part of the mathematical theory of probability, the Doob decomposition theorem gives a unique decomposition of every adapted and integrable stochastic process as the sum of a martingale and a predictable process (or "drift") starting at zero. The theorem was proved by and is named for Joseph L.Mammoth Hot SpringsPlace cell
