Archimedean Atomic Lattice Effect Algebras with Complete Lattice of Sharp Elements

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2010
We study Archimedean atomic lattice effect algebras whose set of sharp elements is a complete lattice. We show properties of centers, compatibility centers and central atoms of such lattice effect algebras.

Efficient modeling of sharp-edge acoustofluidics

open access: yesFrontiers in Physics, 2023
Sharp-edge structures exposed to acoustic fields are known to produce a strong non-linear response, mainly in the form of acoustic streaming and acoustic radiation force. The two phenomena are useful for various processes at the microscale, such as fluid

Calculation of energy consumption for soil cutting horizontal blade by the analysis process [PDF]

open access: yesНаучно-технический вестник Брянского государственного университета, 2019
In the structure of the energy consumption used technical means the construction of roads takes a significant share of the energy spent on cutting soil. Reducing energy costs is largely due to constructive perfection of working bodies in order to improve

On the Uniqueness of Lattice Characterization of Groups

open access: yesAxioms, 2023
We analyze the problem of the uniqueness of characterization of groups by their weak congruence lattices. We discuss the possibility that the same algebraic lattice L acts as a weak congruence lattice of a group in more than one way, so that the ...

The Taikov type inequalities in rigged Hilbert spaces

open access: yesResearches in Mathematics
For the chain $H_+\subset H_0\subset H_-$ of rigged Hilbert spaces we solve the problem of finding sharp Taikov type inequalities that estimate the value of generalized element $\alpha\in H_-$ on smooth elements $u\in H_+$ in terms of the norm of the ...

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

open access: yesFEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
