Microelectrode recordings from the human cervical vagus nerve during maximal breath‐holds

Experimental Physiology, Volume 111, Issue 2, Page 501-516, 1 February 2026.
Abstract Voluntary breath‐holds can be sustained for a long time following training, but ultimately, regardless of duration, the asphyxic break‐point is reached and the apnoea terminated. The physiological changes occurring during the apnoea include a marked increase in sympathetically‐mediated vasoconstriction in non‐essential organs, such as skeletal

Whole‐genome paternal uniparental disomy identified through prenatal single‐nucleotide polymorphism‐based cell‐free DNA screening

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 1, Page 73-78, January 2026.
ABSTRACT Objective Prenatal single‐nucleotide polymorphism (SNP)‐based cell‐free DNA (cfDNA) screening can identify genome‐wide paternal uniparental disomy (GW‐UPDpat), including cases with complete hydatidiform mole with a coexisting fetus (CHMCF), those with placental mesenchymal dysplasia (PMD) and those with a mosaic/chimeric GW‐UPDpat syndrome ...

Modelling of crack propagation in miniaturized and normal SENB specimens based on local failure criterion

Fracture and Structural Integrity
The use of miniaturized specimen testing methods is a promising way to solve the problem of limited materials in RPV monitoring programs. The use of miniature specimens allows the evaluation of fracture toughness from other specimen materials used.

A model independent determination of $|V_{ub}|$ using the global $q^2$ dependence of the dispersive bounds on the $B\to\pi l\nu$ form factors

, 2004
We propose a method to determine the CKM matrix element $|V_{ub}|$ using the global $q^2$ dependence of the dispersive bound on the form factors for $B\to \pi l\nu$ decay. Since the lattice calculation of the $B\to \pi l\nu$ form factor is limited to the

Understanding the Drivers of Carbon–Nitrogen Cycle Variability in CMIP6 ESMs With MAGICC CNit v2.0: Model and Calibration Updates

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.
Abstract Carbon–nitrogen coupling is a critical constraint for improving carbon cycle and climate simulations in Earth system models (ESMs), yet large uncertainties hinder inter‐model comparisons. Here, we present CNit v2.0, an updated representation of the carbon–nitrogen cycle in MAGICC—a widely used reduced‐complexity model (RCM).

Predictive modeling of fracture behavior in Ti6Al4V alloys manufactured by SLM process

Fracture and Structural Integrity
This study focuses on ductile fracture behavior prediction for Ti6Al4V alloys fabricated via Selective Laser Melting (SLM). A modified Gurson-Tvergaard-Needleman (GTN) model characterizes void growth and shear mechanisms under uniaxial stress.

The People\u27s Republic of China\u27s Potential Growth Rate: The Long-Run Constraints [PDF]

, 2014
We estimate the People’s Republic of China’s (PRC’s) potential growth rate in 2012 at 8.7% and at 9.2% for the average of 2008–2012, about the same as the average actual growth rate for this period. This rate is the natural growth rate, that is, the rate

Age‐Associated Dysregulation of Postsynaptic Mitochondria Perturbs Reinnervation Kinetics

Aging Cell, Volume 25, Issue 1, January 2026.
We show that aging results in postsynaptic mitochondrial loss at the neuromuscular junction and impaired muscle reinnervation. In vivo CRISPR knockout of mitochondrial genes, CHCHD10 and CHCHD2, in young muscles led to fragmented endplates, aberrant innervation, and impaired transcriptional maturation of sub‐synaptic myonuclei during regeneration ...
