Oxytocinergic Feedback Circuitries: An Anatomical Basis for Neuromodulation of Social Behaviors

open access: yesFrontiers in Neural Circuits, 2021
Oxytocin (OT) is a neuropeptide produced by hypothalamic neurons and is known to modulate social behavior among other functions. Several experiments have shown that OT modulates neuronal activity in many brain areas, including sensory cortices.

Constructing Cycles in Isogeny Graphs of Supersingular Elliptic Curves

open access: yesJournal of Mathematical Cryptology, 2021
Loops and cycles play an important role in computing endomorphism rings of supersingular elliptic curves and related cryptosystems. For a supersingular elliptic curve E defined over 𝔽p2, if an imaginary quadratic order O can be embedded in End(E) and a ...

Gravitons and loops [PDF]

open access: yesPhysical Review D, 1991
The recently proposed loop representation, used previously to find exact solutions to the quantum constraints of general relativity, is here used to quantize linearized general relativity. The Fock space of graviton states and its associated algebra of observables are represented in terms of functionals of loops. The ``reality conditions'' are realized

Loops and polarization in strong-field QED

open access: yesNew Journal of Physics, 2021
In a previous paper we showed how higher-order strong-field-QED processes in long laser pulses can be approximated by multiplying sequences of ‘strong-field Mueller matrices’.

Shortest loops are pacemakers in random networks of electrically coupled axons

open access: yesFrontiers in Computational Neuroscience, 2012
High-frequency oscillations (HFOs) are an important part of brain activity in health and disease. However, their origins remain obscure and controversial.

On left alternative loops [PDF]

open access: yesMatrix Science Mathematic, 2017
Left alternative loops are loops satisfying (xy)=(xx)y. We construct an infinite family of non-associative non-commutative left alternative loops whose smallest member is of ...

Periodic and Solitary Travelling-Wave Solutions of an Extended Reduced Ostrovsky Equation

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
Periodic and solitary travelling-wave solutions of an extended reduced Ostrovsky equation are investigated. Attention is restricted to solutions that, for the appropriate choice of certain constant parameters, reduce to solutions of the reduced Ostrovsky

Study of palmar dermatoglyphics in vitiligo and normal individuals [PDF]

open access: yesAl Ameen Journal of Medical Sciences, 2015
Background & Objective: Vitiligo is a common idiopathic & hereditary disease characterized by one or more patches of de-pigmented skin due to degeneration or disappearance of cutaneous melanocytes.

ESCO1 and CTCF enable formation of long chromatin loops by protecting cohesinSTAG1 from WAPL

open access: yeseLife, 2020
Eukaryotic genomes are folded into loops. It is thought that these are formed by cohesin complexes via extrusion, either until loop expansion is arrested by CTCF or until cohesin is removed from DNA by WAPL.

Natively unstructured loops differ from other loops. [PDF]

open access: yesPLoS Computational Biology, 2007
Natively unstructured or disordered protein regions may increase the functional complexity of an organism; they are particularly abundant in eukaryotes and often evade structure determination.
