QUOTIENTS, EQUIVALENCE RELATIONS, AND NORMALITY IN NON-ASSOCIATIVE ALGEBRA WITH REGARDS TO LOOPS AND QUASIGROUPS
… quasigroups, and related theorems and varieties. Nonassociative algebra is a relatively new area of mathematics, it came about in the past hundred years, and has started making progress in the past 60 years. In nonassociative algebra, varieties do not necessarily satisfy associativity. Several …

Pharmacological modulation of learning and memory in mice and zebrafish: Implications for Alzheimer’s disease animal models
… of cannabinoid CB1 (CB1) receptors in associative learning in two strains of mice (i.e., C57BL/6J and C3H/HeJ) were first investigated. Here, the effects of the cannabinoid CB1 receptor agonist (i.e., CP55940) and antagonist (i.e., SR141716A) on associative learning were assessed in …

Klassische Konditionierung posturaler Reaktionen beim Menschen, unter Einbeziehung der Kleinhirnfunktion
… on different strategies. For the strategy I an associative process for strategy II a primarily non-associative process was assumed. Nowadays the cerebellum is accepted to be substantially involved in associative and non-associative processes. A patient, suffering from an almost unilateral …

Dynamic key scheduling algorithm for block ciphers using quasigroup string transformation
… table. A method of generating isotope from a non-associative quasigroup using one permutation with full inheritance is achieved. The generic quasigroup string transformation has been analyzed and it is found to be vulnerable to ciphertext only attack which eventually led to the proposal of a …

Enhanced Anisotropic Bounding Surface Model: Implementation and Simulation of Excavation in Soft Cohesive Soils
… enhanced anisotropic bounding surface model with non-associative flow rule, based on the anisotropic critical state theory and bounding surface plasticity. The model has exhibited a great potential to realistically simulate the mechanical behavior of cohesive soils, in non-linear finite element …

Jet Fragmentation at the LHC
… this work, we describe the use of a new class of non-perturbative functions called Generalized Fragmentation Functions (GFFs) as a step towards these goals. This theoretical framework enables the calculation of a broad set of semi-inclusive jet observables. We explore known observables whose …

Constitutive Modelling of Shear Localisation in Saturated Dilative Sand
… deformation of dense sand is evaluated. Then non-coaxial and non-associative flow theories are integrated. Different flow rules are examined for proportional and non-proportional loading paths. Both theories inhibit the tendency to dilate. Non-coaxial Nor-Sand model reduces the overly stiff …

A computational framework for dynamic soil-structure interaction analysis
… problems.With regard to the model, a general, non-associative, elasto-plastic soil model has been developed. An alternate volume change behavior of soils characterizing isotropic compression and extension with exponential and power laws respectively is proposed and included in the model. …

Conditioned Discrimination in the Behavior-Genetic Analysis of the Blow Fly, Phormia Regina
… extension reflex (PER), can be modified by both associative ("learned") and non-associative factors such as the central excitatory state (CES). Data are presented indicating that a procedure previously used to demonstrate classical conditioning in P. regina (the Nelson paradigm) may not be …

Point-line spaces related to Jordan pairs
… the physicist Pascual Jordan invented a non-associative algebraic structure which is now called Jordan algebra. A generalisation of Jordan algebras are the so-called Jordan pairs. In 1975, Ottmar Loos classified all Jordan pairs with finite dimension. As a matter of fact, the list of …

Individual differences in autonomic response to secondary aversive events
… an avoidance model to explain this phenomenon. An experiment based on a design used by Hare and Blevings (1975) was conducted to investigate the possibility that this avoidance takes place at a perceptual level.</p><p>Seventy-six female subjects were differentiated into high and low ego …

The effects of changing the interstimulus interval during habituation in Caeorhaditis elegans
… habituation is one of the simplest forms of non-associative learning, its underlying neural mechanisms are still not well understood. One factor that plays a key role in habituation is interstimulus interval (ISI). Understanding, at a behavioural level, the effects that ISI has on habituation …

Mechanical Behavior of Soil-Bentonite Cutoff Walls
… case of a more complicated existing model, is a non-associative Modified Cam Clay type model that has parameters to change the yield surface and plastic potential surface into ellipses of varying shapes. The RS model was implemented into the finite element program SAGE. A finite element model was …

Development of Novel Computational Simulation Tools to Capture the Hysteretic Response and Failure of Reinforced Concrete Structures under Seismic Loads
… conditions. An elastoplastic formulation, with a non-associative flow rule to capture compression-dominated response, is combined with a rotating smeared-crack model to capture the damage associated with tensile cracking. The proposed model resolves issues which characterize existing concrete …

Syneresis and Rheology Mechanisms of a Latex-HEUR Associative Thickener System
… were hydroxyethyl celluloses (HECs), a type of non-associative thickener that is relatively inexpensive and synthesized from cellulose, which is abundant. However, coatings that are modified with HECs tend to suffer from poor leveling and syneresis (phase separation). HECs have since been …

The Koszul dual to n-Lie, n-Com algebras, and Young tableaux
… in which $C_e(1)$ is a commutative unital associative $k$-algebra acting on the other components, which is almost associative. Furthermore, we briefly construct an analog of the Killing form for $3$-Com algebras, denoted as $\kappa$, and define non-degeneracy when the form is non-degenerate …

Ontogeny of contextual fear conditioning: behavioral, neuropharmacological and molecular mechanisms
