Memory Efficient Method for Electromagnetic Multi-Region Models Using Scattering Matrices

Mathematical and Computational Applications, 2018
This paper describes the scattering matrix approach to obtain the solution to electromagnetic field quantities in harmonic multi-layer models. Using this approach, the boundary conditions are solved in such way that the maximum size of any matrix used ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

An Insight on the Microwave Circulator Theory

IEEE Access
This contribution is devoted to clarifying the analytical derivation of the microwave circulator matrixes. Although this topic seems well-acknowledged, the approach of many books is affected by an initial error that, in turn, affects the final result. It

The effect of short ray trajectories on the scattering statistics of wave chaotic systems

, 2009
In many situations, the statistical properties of wave systems with chaotic classical limits are well-described by random matrix theory. However, applications of random matrix theory to scattering problems require introduction of system specific ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

FEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Model-independent description of the light nucleus-nucleus elastic scattering at intermediate energies [PDF]

Ядерна фізика та енергетика, 2007
We propose a new approach, based on the evolutionary algorithm, which enables to extract a scattering matrix S(l) as a complex function of angular momentum l directly from the nucleus-nucleus elastic scattering data at intermediate energies without any

A general T-matrix approach applied to two-body and three-body problems in cold atomic gases

, 2012
We propose a systematic T-matrix approach to solve few-body problems with s-wave contact interactions in ultracold atomic gases. The problem is generally reduced to a matrix equation expanded by a set of orthogonal molecular states, describing external ...

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

FEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...
