An Isotropic Areal Filter Based on High-Order Thin-Plate Spline for Surface Metrology

IEEE Access, 2019
Isotropy, end effect suppression, calculation efficiency and robustness are basic requirements of areal filters for surface metrology. However, current areal filters cause problems in different aspects, which cripples the operation of surface metrology ...

Isotropy of Algebraic Theories

Electronic Notes in Theoretical Computer Science, 2018
Abstract To every small category or topos one may associate its isotropy group, which is an algebraic invariant capturing information about the behaviour of automorphisms. We investigate this invariant in the particular situation of algebraic theories, thus obtaining a group-theoretic invariant of algebraic theories.

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

FEBS 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 ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Cubature, Approximation, and Isotropy in the Hypercube [PDF]

SIAM Review, 2017
A common problem especially in computational (applied) mathematics is the so-called curse of dimensionality. This means that the computational costs of solving numerical problems (approximation, compression, quadratures) increase much faster (e.g., exponentially) with dimension as is initially expected.

Multidimensional Profiling of MRI‐Negative Temporal Lobe Epilepsy Uncovers Distinct Phenotypes

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Although hippocampal sclerosis (TLE‐HS) represents the most frequent cause of temporal lobe epilepsy (TLE), up to 30% of patients show no lesion on visual MRI inspection (TLE‐MRIneg). These cases pose diagnostic and therapeutic challenges and are underrepresented in surgical series.

Fully Printed 3-D Antennas With Wideband Radiation Isotropy Based on Annular Currents Models

IEEE Open Journal of Antennas and Propagation, 2023
Internet of Things (IoT) devices require orientation insensitive communication and a small footprint. Wireless communication should be maintained across the whole operation band, hence electrically small antennas (ESAs) with wideband radiation isotropy ...

Advancing Age Modulates Associations Between Cognitive Impairment and Brain Volumes in Early MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Cognitive impairment is common in multiple sclerosis (MS), but manifestations following the first demyelinating event are relatively unexplored. We investigated cross‐sectional associations between magnetic resonance imaging (MRI)–derived brain volumes and the presence of cognitive impairment outcomes five years after the first ...

Aspects of Isotropy in Small Categories

, 2017
In the paper \cite{FHS12}, the authors announce the discovery of an invariant for Grothendieck toposes which they call the isotropy group of a topos. Roughly speaking, the isotropy group of a topos carries algebraic data in a way reminiscent of how the ...
