Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.

Distribusi Medan Magnet Pada Solenoid [PDF]

open access: yes, 2016
The magnetic field is a field that is formed by moving electrical charges (electric current) which cause emergence of force in an electric charge that moves. Near all object that characteristic of metal can be pulled by a magnet.

Affective CT‐touch attenuates cortical responses and subjective attention during temporal summation of second pain

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The study investigated the modulatory effects of affective touch on temporal summation of second pain (TSSP) in 32 romantic couples (N = 64). The design included a dyadic session (partner's CT‐optimal stroking vs. static touch) and an individual session (robotic CT‐touch vs. vibration control).

Cryogen‐Aided Chromatographic Purification of Millimole Quantities of Methane for Spectroscopic Clumped Isotope Analysis

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Quantum cascade laser absorption spectroscopy (QCLAS) is a fast and reliable method for analyzing the bulk (𝛿13C‐CH4, 𝛿D‐CH4) and clumped isotopic (∆13CH3D and ∆12CH2D2) composition of methane. However, precise measurements of ∆12CH2D2 require 0.5 to 1.8 mmol of purified methane (equivalent to 15 to 40 mL at STP).

The spectrum of a solenoid

open access: yes, 2019
Given a sequence of regular finite coverings of complete Riemannian manifolds, we consider the covering solenoid associated with the sequence. We study the leaf-wise Laplacian on the covering solenoid. The main result is that the spectrum of the Laplacian on the covering solenoid equals the closure of the union of the spectra of the manifolds in the ...

Time‐Conditioned Zero‐Shot Self‐Supervised Reconstruction for Accelerated 3D Ultra‐Low‐Field MRI

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 3, Page 1303-1312, September 2026.
ABSTRACT Purpose Ultra‐low‐field (ULF) MRI provides a cost‐effective, portable imaging option but has relatively low SNR and long acquisition times compared to standard clinical scans. This study presents a time‐conditioned zero‐shot self‐supervised learning image reconstruction framework (ULF‐ZS‐SSL) to accelerate 3D‐acquired single‐coil ULF MRI ...

A Stopped‐Flow Instrument for Millisecond Timescale Reaction Monitoring on a Standard NMR Spectrometer

open access: yesMagnetic Resonance in Chemistry, Volume 64, Issue 8, Page 711-728, August 2026.
A new stopped‐flow instrument allows kinetic measurements of reactions 10 milliseconds after initiating them by mixing in a flow cell inserted into a standard NMR probe and spectrometer. High‐speed video, pressure and NMR line‐shape data are used to characterise mixing and stopping, and a protodeboronation reaction with a 5‐millisecond half‐life used ...

Dual-latching solenoid-actuated valve assembly [PDF]

open access: yes, 1994
A tube-type shutoff valve is electrically positioned to its open or closed position by a concentric electromagnetic solenoid. The valve is dual latching in that the armature of the solenoid maintains the sliding tube of the valve in an open or closed ...

A System for Retrofitting Conventional MRI Systems for Simultaneous Multinuclear MRI/MRS

open access: yesNMR in Biomedicine, Volume 39, Issue 8, August 2026.
We present a low‐cost system for retrofitting conventional narrow‐band MRI spectrometers with simultaneous multinuclear capability using heterodyne frequency translation. The system supports up to four nuclei and 16 receive channels, with reconfigurable transmit modes and inherent phase stability through a shared local oscillator architecture ...
