On the momentum term in gradient descent learning algorithms

open access: yesNeural Networks, 1999
A momentum term is usually included in the simulations of connectionist learning algorithms. Although it is well known that such a term greatly improves the speed of learning, there have been few rigorous studies of its mechanisms.

Location-dependent synaptic plasticity rules by dendritic spine cooperativity

open access: yesNature Communications, 2016
Inputs to functionally related synapses have been suggested to show cooperative summation, although the rules governing these interactions are unclear. Here, Weber et al.

Giant momentum-dependent spin splitting in centrosymmetric low- Z antiferromagnets

open access: yes, 2020
The traditional bulk Rashba effect predicts spin-orbit coupling induced wave-vector-dependent spin splitting between energy bands in nonmagnetic solids that lack spatial inversion symmetry.

FEATURES MORPHOLOGY ABNORMAL FORMS OF ERYTHROCYTES BY ATOMIC FORCE MICROSCOPY

open access: yesНаука. Инновации. Технологии, 2022
Annotation The possibility of using atomic force microscopy (AFM) to qualitatively assess the morphology and the visualization of abnormal forms of red blood cells (RBCs), in comparison with traditional methods of optical microscopy, was studied in this ...

Tidal dynamics and energy budget in the Gulf of California

open access: yesCiencias Marinas, 2000
The dynamics and energetic behavior of the tides in the Gulf of California were studied with their principal constituents. Three cases were chosen: the first included the M2 constituent; the second, the two principal semidiurnal constituents; and the ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Spatial momentums

open access: yesInterstices: Journal of Architecture and Related Arts
A fixed and final architecture often follows the act of drawing, but what if architecture were to remain a drawing, with the vitality of an open sketch? Drawing brings performative gestures to life through records of its making—its traces. This research experiments with these traces, using their performative possibility to re-frame and alter ...

Clinically Relevant Outcome Measures in Women With Adrenoleukodystrophy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Adrenoleukodystrophy is a rare inherited peroxisomal disease caused by pathogenic variants in the ABCD1 gene located on the X chromosome. Although the most severe central nervous system and adrenal complications typically affect only men with adrenoleukodystrophy, the majority of women develop myeloneuropathy symptoms in adulthood.
