Multiomic single nuclei profiling the mouse hippocampus reveals that ACSS2 confers neuronal resilience to tauopathy

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Epigenomic dysregulation contributes to Alzheimer's disease (AD) and related tauopathies. Acetyl‐CoA synthetase 2 (ACSS2), a nuclear‐localized metabolic enzyme in neurons, supports histone acetylation and learning‐related gene expression.

Diffusion Tensor MRI and Spherical‐Deconvolution‐Based Tractography on an Ultra‐Low Field Portable MRI System

Human Brain Mapping, Volume 47, Issue 2, February 1, 2026.
A Portable ULF scanner (1a) imaged a subject (1b) and phantom (1c) to give T2 (2a) and DW (2b) acquisitions alongside a regularised phantom fieldmap (2c). These were processed to give corrected DTI (3a) and CSD (3b) derivatives and were used for whole‐brain tractography (3c) in a feasible acquisition duration.

Multi-step capacitor-splitting SAR ADC

Electronics Letters, 2010
A new architecture is proposed which reduces the power consumption and capacitor area in successive approximation register (SAR) analogue-to-digital converters (ADCs). Two identical capacitor-splitting capacitor arrays are used in a two-step process for quantisation, and this significantly reduces the switching power and capacitor area.

State‐of‐the‐Art Strategies for Circular RNA in Cancers: Opportunity and Challenge

MedComm, Volume 7, Issue 2, February 2026.
Overview of circular RNA in tumors. ABSTRACT Circular RNAs (circRNAs) are characterized by their covalently closed structure, remarkable stability, and precise spatiotemporal regulation, evolving from once‐overlooked transcriptional byproducts to pivotal molecular regulators.

Two-step split-junction SAR ADC

Electronics Letters, 2010
A new architecture is proposed to reduce the power consumption and capacitor area in successive-approximation register analogue-to-digital converters (SAR ADCs). Two split-junction binary-weighted capacitor arrays are used in a coarse/fine quantisation scheme. This reduces both the power consumption and the capacitor area to a small fraction of that of
