STUDY ON THE CRACK BRANCHING BEHAVIOR DURING CRACK PROPAGATION INFLUENCED BY CONSTRAINT

open access: yesJixie qiangdu, 2022
During the crack propagation process, the crack branching behavior makes fracture more unpredictable. In this work, three kinds of crack branching models were selected, and the FEM simulations based on GTN(Gurson-Tvergaard-Needleman) damage model were ...

$b \to s l \bar l $ in the minimal supergravity model

open access: yes, 1996
The $b \rightarrow s l^+ l^-$ process is studied in the minimal supergravity model in detail. Taking account of the long distance contributions from the $c\overline{c}$ resonances, we calculate the branching ratio and the lepton forward-backward ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

open access: yesFEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

The local structure of multiple solutions of a non-linear equation in the case of multidimensional degeneration

open access: yesИзвестия высших учебных заведений. Поволжский регион: Физико-математические науки, 2023
Background. When studying mathematical models of physical processes described by nonlinear equations with a parameter, situations are identified when the parameter reaches a certain critical value, which leads to a violation of unambiguity in the ...

Path-valued branching processes and nonlocal branching superprocesses

open access: yes, 2014
A family of continuous-state branching processes with immigration are constructed as the solution flow of a stochastic equation system driven by time-space noises.

Identifying transcription factors controlling the basal expression of human MRP4 highlights a substantial role for Sp1

open access: yesFEBS Open Bio, EarlyView.
The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

open access: yesFEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Regulatory mechanisms of branching morphogenesis in mouse submandibular gland rudiments

open access: yesJapanese Dental Science Review, 2018
Summary: Branching morphogenesis is an important developmental process for many organs, including the salivary glands. Whereas epithelial–mesenchymal interactions, which are cell-to-cell communications, are known to drive branching morphogenesis, the ...
