The effect of surface tension on axisymmetric confined viscous gravity currents

open access: yesPartial Differential Equations in Applied Mathematics
We consider the radial spreading of an axisymmetric viscous gravity current, in which fluid released from a point source at a constant flux is confined vertically to a narrow gap between two horizontal plates.

Coluna de areia para medir a retenção de água no solo: protótipos e teste Use of sand column to measure soil water retention: prototypes and test

open access: yesCiência Rural, 2006
A curva de retenção de água no solo é construída usando-se várias estratégias e metodologias. Para baixas tensões, o uso de "mesa de tensão" tem predominado, apesar de alguns modelos apresentarem restrições (desvantagens e limitações).

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Nondestructive testing principle and technology of tension of anchor bolts

open access: yesYantu gongcheng xuebao
Based on its multi-contact surface characteristics, an indoor model is built to study the vibration characteristics of the anchorage system of an anchor bolt. By installing an acceleration sensor at the top of the unstressed section of the anchor bolt to

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

The development and performance evaluation of diagonal tension cracks control devices

open access: yesJournal of Asian Architecture and Building Engineering
The cause of diagonal tension cracks is the drying shrinkage of the initial concrete, which causes them to appear at the corners of square openings, which are the most vulnerable areas to stress. Looking specifically at the cause from a structural aspect,

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

open access: yesMolecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

RECONSTRUCTION OF BRIDGES USING METHOD OF LATERAL COMPRESSION OF SPAN STRUCTURES

open access: yesНаука и техника, 2006
The paper considers a new technical solution of strengthening the existing assembly span structures made of T-beams with diaphragms with the help of lateral compression device. The peculiar feature of the solution consists in fixing the stressed elements

E2A selectively regulates TGF‐β–induced apoptosis in KRAS‐mutant non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
Ability to induce apoptosis by TGF‐β is frequently lost in advanced lung adenocarcinoma despite intact TGF‐β signaling. We identify E2A as a mutant KRAS–dependent mediator of resistance to TGF‐β–induced apoptosis. TGF‐β induces E2A via SMAD3 in mutant KRAS cells, and E2A silencing restores apoptosis and enhances radiation response in cell lines ...
