Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI

open access: yesChemie Ingenieur Technik, EarlyView.
This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.

Ion Chemistry of VX Surrogates and Ion Energetics Properties of VX: New Suggestions for VX Chemical Ionization Mass Spectrometry Detection

open access: yes, 2016
Room temperature rate constants and product ion branching ratios have been measured for the reactions of numerous positive and negative ions with VX chemical warfare agent surrogates representing the amine (triethylamine) and organophosphonate (diethyl ...

Coupled heat and mass transfer in reactive parallel‐plate flow: A perturbative Graetz model with modal symmetry and Arrhenius kinetics

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
A perturbative Graetz model describes coupled heat and mass transfer in reactive Couette–Poiseuille flow between parallel plates. Viscous dissipation and heat of reaction produce a small temperature rise, which enhances Arrhenius reaction rates and modestly accelerates axial species conversion in the small‐Brinkman‐number regime.

Ion-molecule reactions of O,S-Dimethyl methylphosphonothioate : Evidence for intramolecular sulfur oxidation during VX perhydrolysis [PDF]

open access: yes, 2009
The alkaline perhydrolysis of the nerve agent O-ethyl S-[2-(diisopropylamino)ethyl] methylphosphonothioate (VX) was investigated by studying the ion-molecule reactions of HOO(-) with O,S-dimethyl methylphosphonothioate in a modified linear ion-trap mass ...

Do preclinical seizure models predict success or failure in anti‐seizure drug development? A retrospective analysis of 89 compounds with divergent clinical outcomes for epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Anti‐seizure medication (ASM) discovery remains a major challenge despite over 30 commercially available options. One persistent obstacle for any promising candidate compound to successfully move from preclinical study to clinical approval has been the ambiguity in preclinical model selection.

The Development and Characterization of VX-770 Molecular Probes [PDF]

open access: yes, 2016
Cystic fibrosis is the most common genetic disease affecting the Canadian population. It is caused by mutations in the cystic fibrosis transmembrane conductance regulator gene, and there is currently no cure.

A. Effects of VX-809 alone and in combination with P. aeruginosa on CFBE cells.

open access: yes, 2015
VX-809 (3 μM, 48 hours) increased Cl secretion compared to vehicle treated control in CFBE cells. PA01, PA14, PAK and 6 clinical isolates of P.

The multiple hit model of infantile and epileptic spasms: The 2025 update

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Infantile and epileptic spasms syndrome (IESS) is a developmental and epileptic encephalopathy manifesting with epileptic spasms and poor neurodevelopmental outcomes. There is an urgent need for the development of more effective and tolerated therapies.

Programmable solar‐blind ultraviolet sensors enabling integrated single‐pixel sensing and neuromorphic processing

open access: yesInfoMat, EarlyView.
A Schottky photodiode based on (Al0.14Ga0.86)2O3 was developed, in which the sensing and processing functions were temporally decoupled through bias voltage modulation. By integrating single‐pixel imaging with a reservoir computing architecture, a comprehensive intelligent vision system was constructed.

Sparse Graphs With Local Covering Conditions on Edges

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT In 1988, Erdős suggested the question of minimizing the number of edges in a connected n $n$‐vertex graph where every edge is contained in a triangle. Shortly after, Catlin, Grossman, Hobbs, and Lai resolved this in a stronger form. In this paper, we study a natural generalization of the question of Erdős in which we replace “triangle” with ...
