Purification, Fluorescent Labeling, and Detyrosination of Mammalian Cell Tubulin for Biochemical Assays

open access: yesCytoskeleton, EarlyView.
ABSTRACT Microtubules play essential roles in numerous cellular processes. All microtubules are built from the protein tubulin, yet individual microtubules can differ spatially and temporally due to their tubulin isotype composition and post‐translational modifications (PTMs).

Numerical Assessment of Novel Helical/Spiral Grafts with Improved Hemodynamics for Distal Graft Anastomoses. [PDF]

open access: yesPLoS ONE, 2016
In the present work, numerical simulations were conducted for a typical end-to-side distal graft anastomosis to assess the effects of inducing secondary flow, which is believed to remove unfavourable flow environment.

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

Zebrafish ventral gastrula fate map reveals neural crest progenitor domain

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Fate maps relate progenitor cell positions to later fates and locations of their progeny, revealing early embryonic organization. Previous zebrafish fate maps identified the origin of germ layers and derivative cell fates, but ventral gastrula progenitor domains were not fully resolved. In particular, the neural crest, a multipotent

A Numerical Investigation of the Effects of Piston Bowl Geometry and Spray Angle on Combustion, Performance and Emission of a Diesel Engine

open access: yesEnergy Science &Engineering, EarlyView.
A piston bowl's design and spray angle improve air‐fuel mixing, resulting in more complete combustion and higher efficiency. Ansys Forte 2023 R1 a CFD software was used to analyze the effects of five combustion chamber geometries of cylinder, modified re‐entrant, re‐entrant, double‐stepped, and stepped on engine performance, combustion, and emission ...

Hydrogen‐Enriched Tri‐Fuel Combustion for Low‐Carbon Engines at Medium Engine Load: A Comprehensive CFD Analysis

open access: yesEnergy Science &Engineering, EarlyView.
CFD analysis of a diesel–CH4–H2 tri‐fuel engine shows that increasing hydrogen energy share (HES) enhances mixing and accelerates combustion, improving pressure, efficiency, and reducing CO and soot. At 60% HES, ISFC improves 26.2%, soot drops 95%, while NOx increases due to higher temperatures. ABSTRACT The global commitment to achieve net‐zero carbon

Experimental Study and Numerical Simulation of a Newly Developed Desilting Channel with Swirling Flow

open access: yes工程科学与技术, 2022
Excessive sediment content during water diversion will lead to a series of engineering problems. In order to solve the problem of water and sediment separation during water diversion of sediment-laden rivers, sediment discharge facilities are often set ...

Lactation, Childrearing, and Gender Justice

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT In this article, I discuss the significance of early infant feeding choices for the goal of gender justice. Focusing on human lactation practices, I identify Exclusive Gestational Nursing (EGN) as the norm in advanced industrial societies, which creates the expectation and permission for gestators, and only gestators, to nurse children, and ...

Sonographic Diagnosis of an Intercostal Artery Pseudoaneurysm: A Case Report and Literature Review

open access: yesJournal of Clinical Ultrasound, EarlyView.
A 63‐year‐old male presented to the emergency department after being found unconscious during a welfare check. Following a prolonged three‐month hospital admission, the patient developed left flank pain. Spectral Doppler ultrasound revealed a large isoechoic lesion with layering echoes, and spectral Doppler demonstrated bidirectional flow.
