Fourier Transform of the Lippmann-Schwinger Equation: Solving Vectorial Electromagnetic Scattering by Arbitrary Shapes

open access: yesMathematics, 2023
In Electromagnetics, the field scattered by an ensemble of particles—of arbitrary size, shape, and material—can be obtained by solving the Lippmann–Schwinger equation.

Planewave density interpolation methods for 3D Helmholtz boundary integral equations

open access: yes, 2019
This paper introduces planewave density interpolation methods for the regularization of weakly singular, strongly singular, hypersingular and nearly singular integral kernels present in 3D Helmholtz surface layer potentials and associated integral ...

Singularity confinement and algebraic integrability [PDF]

open access: yesJournal of Mathematical Physics, 2004
Two important notions of integrability for discrete mappings, algebraic integrability and singularity confinement, have been used for discrete mappings. Algebraic integrability is related to the existence of sufficiently many conserved quantities and singularity confinement is associated with the local analysis of singularities.

Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments

open access: yesFEBS Open Bio, EarlyView.
Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.

Profiling the effect of low frequency mechanical vibration on the metabolic and oxidative stress responses of A431 carcinoma

open access: yesFEBS Open Bio, EarlyView.
20 Hz mechanical vibration induced A431 cancer cells' apoptosis without such effect on other healthy cell lines of L929 and C2C12. Lowered glucose consumption is observed specifically in A431. The expressions of ROS, HMGB1, and HSP1 levels initially increase and subsequently decrease in the cancer cell line, as opposed to L929 and C2C12, which ...

Current trends in single‐cell RNA sequencing applications in diabetes mellitus

open access: yesFEBS Open Bio, EarlyView.
Single‐cell RNA sequencing is a powerful approach to decipher the cellular and molecular landscape at a single‐cell resolution. The rapid development of this technology has led to a wide range of applications, including the detection of cellular and molecular mechanisms and the identification and introduction of novel potential diagnostic and ...

Matrix: a complex amalgam of structures and functions in tumor microenvironment

open access: yesFEBS Open Bio, EarlyView.
The matrix is a dynamic, intricate three‐dimensional mesh of biomolecules with both structural and functional properties. This review deals with the complexity of this ‘molecular amalgam’ in the tumor microenvironment and highlights its importance in the maintenance and evolution of tumors by describing certain matrix biomolecules, such as ...

Integrating singular functions on the sphere [PDF]

open access: yesJournal of Mathematical Physics, 1997
We obtain rigorous results concerning the evaluation of integrals on the two-sphere using complex methods. It is shown that for regular as well as singular functions which admit poles, the integral can be reduced to the calculation of residues through a limiting procedure.

Phenotypic plasticity in a novel set of EGFR tyrosine kinase inhibitor‐adapted non‐small cell lung cancer cell lines

open access: yesFEBS Open Bio, EarlyView.
Phenotypic plasticity in a newly established set of EGFR inhibitor‐adapted NSCLC cell lines during adaptation and in established cell lines. Here, we introduce novel sublines of the EGFR‐mutant non‐small cell lung cancer (NSCLC) cell lines HCC827 and HCC4006 adapted to the EGFR kinase inhibitors gefitinib (HCC827rGEFI2μm, HCC4006rGEFI1μm), erlotinib ...

On local properties of singular integral

open access: yesUkrains’kyi Matematychnyi Zhurnal, 2023
UDC 517.5 Letγbe a regular curve. We study the local properties of singular integrals in the Hαα+β(t0,γ)class of functions. We obtain a strengthening of the Plemelj\–Privalov theorem for functions from the classHαα+β(t0,γ). It is proved that, at the pointt0,of increased smoothness for α+β<1,there is only a logarithmic loss.
