Framework for X‐ray mirror surface shape fitting

Journal of Synchrotron Radiation, EarlyView.
The closed‐form expressions for elliptic cylinders, hyperbolic cylinders, ellipsoids, hyperboloids, and diaboloids used for X‐ray mirror surface shapes are summarized. Additionally, a four‐layer framework to fit the measured surface shape data in slope or height for convenient X‐ray mirror surface characterization is proposed.For accurate ...

A geophysical investigation of the Roter Kamm impact crater, Namibia

Meteoritics &Planetary Science, EarlyView.
Abstract The Roter Kamm impact crater is located in the southern Namib Desert. The crater has a diameter of 2.5 km and belongs to the category of simple, bowl‐shaped impact craters, with an elevated rim of fractured target rock. The crater's interior is completely buried beneath sediments, preventing extensive surface investigations of the bedrock ...

The role of acid‐base balance in cerebrovascular and ventilatory responses to CO2 during 10 h normobaric hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...

Co‐ingesting whey protein with dual‐source carbohydrate enhances amino acid availability without compromising post‐exercise liver glycogen resynthesis

The Journal of Physiology, EarlyView.
Abstract figure legend Graphical overview of the experimental study. The upper‐left panel presents the research question, and the bottom‐left panel provides a schematic overview of the experimental design. The right‐hand panel depicts repetitive spectral data obtained by magnetic resonance spectroscopy, liver glycogen content during the 5 h post ...

Dynamic Transitions for Fast Joint Acquisition and Reconstruction of CEST‐Rex$$ {R}_{ex} $$ and T1$$ {T}_1 $$

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2153-2168, April 2026.
ABSTRACT Purpose This work proposes a method for the simultaneous estimation of the exchange‐dependent relaxation rate Rex$$ {R}_{ex} $$ and the longitudinal relaxation time T1$$ {T}_1 $$ from a single acquisition. Methods A novel acquisition scheme was developed that combines CEST saturation with an inversion pulse and a Look‐Locker readout to capture

Ultimate Intrinsic SNR in the Torso of Realistic Body Models

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2409-2419, April 2026.
ABSTRACT Purpose This work aims to investigate how the ultimate intrinsic signal‐to‐noise ratio (uiSNR) varies with increasing static magnetic field B0$$ {B}_0 $$ in the torso of realistic body models. Methods A dipole cloud was positioned around the realistic body model and randomly excited.

Learning hydrocracking reaction dynamics via neural ODEs: A data‐driven, gradient‐interpretable lumped modelling framework

The Canadian Journal of Chemical Engineering, Volume 104, Issue 3, Page 1372-1386, March 2026.
This work demonstrates the application of neural ordinary differential equations (neural ODEs) for learning hydrocracking reaction kinetics directly from data, achieving robust predictions under noise and sparsity while preserving mechanistic interpretability through gradient‐based analysis of temperature‐ and concentration‐dependent reaction rates ...
