Gauges and Cosmological Backreaction

, 2009
We present a formalism for spatial averaging in cosmology applicable to general spacetimes and coordinates, and allowing the easy incorporation of a wide variety of matter sources. We apply this formalism to a Friedmann-LeMaitre-Robertson-Walker universe

Phase‐Pole‐Free Images and Smooth Coil Sensitivity Maps by Regularized Nonlinear Inversion

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 134-145, July 2026.
ABSTRACT Purpose Phase singularities are a common problem in image reconstruction with auto‐calibrated sensitivities due to an inherent ambiguity of the estimation problem. The purpose of this work is to develop a method for detecting and correcting phase poles in non‐linear inverse (NLINV) reconstruction of MR images and coil sensitivity maps ...

On the self-consistent spin-wave theory of layered Heisenberg magnets

, 1999
The versions of the self-consistent spin-wave theories (SSWT) of two-dimensional (2D) Heisenberg ferro- and antiferromagnets with a weak interlayer coupling and/or magnetic anisotropy, that are based on the non-linear Dyson-Maleev, Schwinger, and ...

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

Biological Reviews, Volume 101, Issue 3, Page 1463-1478, June 2026.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Inflammatory Burden Index as a promising new marker for predicting surgical and oncological outcomes in colorectal cancer

Annals of Gastroenterological Surgery
Aims The prognosis of colorectal cancer (CRC) has been historically reliant on the Tumor Node Metastasis (TNM) staging system, but there is variability in outcomes among patients at similar stages.

FENCE: Flexible Electric Noise Reduction Endo‐Shield for the Suppression of Electromagnetic Interference in Low‐Field MRI

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
Electromagnetic interference (EMI) is a significant challenge for low‐field MRI. Traditional EMI mitigation approaches either limit portability or demand advanced hardware. We present FENCE (Flexible Electromagnetic Noise reduCtion Endo‐shield), a novel approach for EMI mitigation using flexible PCBs placed inside the RF coil.

Sex‐Specific Associations of Inflammatory Biomarkers With All‐Cause and Cardiovascular Mortality Across Glycaemic Status: A Prospective UK Biobank Study

Diabetes, Obesity and Metabolism, Volume 28, Issue 6, Page 4728-4740, June 2026.
ABSTRACT Aims To explore sex‐specific heterogeneity in the prognostic discrimination of inflammatory markers for mortality across different glycaemic states. Methods This prospective cohort study included 450 438 participants from the UK Biobank (median follow‐up: 15.3 years), stratified by sex and glycaemic status.

Neural Network Model for Apparent Deterministic Chaos in Spontaneously Bursting Hippocampal Slices

, 2002
A neural network model that exhibits stochastic population bursting is studied by simulation. First return maps of inter-burst intervals exhibit recurrent unstable periodic orbit (UPO)-like trajectories similar to those found in experiments on ...

Severe, Non‐apneic Respiratory Dysfunction and Hypoxia following Generalized Convulsive Seizures

Annals of Neurology, Volume 99, Issue 5, Page 1263-1276, May 2026.
Objective Sudden unexpected death in epilepsy (SUDEP) is a devastating consequence of some generalized convulsive seizures (GCS). Recent work has focused on seizure related apnea as a biomarker of SUDEP risk, frequently without characterizing the adequacy of non‐apneic ventilation or identifying other dysfunctional breathing patterns.

Elevated inflammatory burden index increases mortality in adults with chronic inflammatory airway diseases: a nationwide cohort study

BMC Pulmonary Medicine
Objective The objective of this study was to investigate the potential association between the inflammatory burden index (IBI) and the prevalence of chronic inflammatory airway diseases (CIAD), as well as mortality rates among individuals diagnosed with ...
