Physical activity attenuates the association between allostatic load and early Alzheimer's disease‐related biomarkers in older adults

open access: yesAlzheimer's &Dementia: Translational Research &Clinical Interventions, Volume 12, Issue 2, April/June 2026.
Abstract INTRODUCTION Allostatic load (AL), an index of cumulative physiological dysregulation from chronic stress, may contribute to Alzheimer's disease (AD) pathophysiology by accelerating brain aging. Higher AL has been associated with AD‐related biomarkers, suggesting a mechanistic connection.

NeuroGen: Activation optimized image synthesis for discovery neuroscience

open access: yesNeuroImage, 2022
Functional MRI (fMRI) is a powerful technique that has allowed us to characterize visual cortex responses to stimuli, yet such experiments are by nature constructed based on a priori hypotheses, limited to the set of images presented to the individual ...

Next‐Generation Electron Linear Accelerators for Compact Accelerator‐Driven Neutron Sources

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
High‐gradient electron linear accelerators (linacs) enable cost‐effective, high‐performance compact accelerator‐driven neutron sources (CANSs) for industrial applications. Comparing with existing CANS, we show that high‐gradient linacs open a previously unexplored region of the CANS landscape, enabling accessible stress diffractometry with competitive ...

The Beauty of Symmetry: Common-mode rejection filters for high-speed interconnects and balanced microwave circuits [PDF]

open access: yes, 2017
Common-mode rejection filters operating at microwave frequencies have been the subject of intensive research activity in the last decade. These filters are of interest for the suppression of common-mode noise in high-speed digital circuits, where ...

Stand-alone wearable system for ubiquitous real-time monitoring of muscle activation potentials [PDF]

open access: yes, 2018
Wearable technology is attracting most attention in healthcare for the acquisition of physiological signals. We propose a stand-alone wearable surface ElectroMyoGraphy (sEMG) system for monitoring the muscle activity in real time.

The Development of Hippocampal‐Cortical Functional Connectivity in Infants and Toddlers

open access: yesHuman Brain Mapping, Volume 47, Issue 4, March 2026.
This study traces the early maturation of hippocampal‐cortical coupling along the hippocampal long‐axis across the first 2 years of life, revealing early increases with canonical memory regions followed by prolonged fine‐tuning with memory, salience, and attention networks. These developing interactions may support evolving long‐term memory capacity in

Ultracompact monolithic integration of balanced, polarization diversity photodetectors for coherent lightwave receivers [PDF]

open access: yes, 1992
The authors have monolithically integrated an optical front-end on InP for balanced, polarization-diversity coherent lightwave reception which is only 1.3-mm long. Low on-chip insertion loss (

The Complexity of Multidimensional Learning in Agriculture

open access: yesEconometrica, Volume 94, Issue 2, Page 465-503, March 2026.
Studies on agricultural technology adoption often focus on one input, practice, or package, which is analytically useful, but may overlook the complexities involved with multidimensional learning needed for a lot of agricultural decisions. In Kenya, we study farmers' dynamic learning (from oneself and others) and adoption decisions over six seasons ...

The insula, a grey matter of tastes: a volumetric MRI study in dementia with Lewy bodies

open access: yesAlzheimer’s Research & Therapy, 2020
Background Despite the growing number of discoveries during the past decades about its functions, the insula remains a mysterious ‘island’. In addition to its involvement in basic functions such as gustation and interoception, the insular cortex is now ...

Multifunctional E‐Tattoos Based on Electrospun PVBVA Fibers Coated with Ti3C2Tx MXene for Energy Harvesting, Energy Storage, and Biometric Sensing

open access: yesAdvanced Science, Volume 13, Issue 11, 23 February 2026.
This study explores a novel E‐tattoo made from PVBVA fibers coated with Ti3C2Tx MXene. The device is designed to harvest energy directly from the human body, providing power for itself. The research demonstrates the E‐tattoo's capability for charge storage and its potential for health monitoring through integrated ECG and EMG sensing, all within a ...
