Integral Transforms of Fourier Cosine Convolution Type

Journal of Mathematical Analysis and Applications, 1999
The author investigates integral transforms of the type \[ g(x)= \int^\infty_0 [k(x+ y)+ k(| x-y|)] f(y)dy,\quad x\in\mathbb{R}_+ \] in spaces \(L_p(\mathbb{R}_+)\), \(1\leq p\leq 2\). It is proved that this transformation is a bounded operator from \(L_p(\mathbb{R}_+)\), \(1\leq p\leq 2\) into \(L_q(\mathbb{R}_+)\), \(p^{-1}+ q^{-1}= 1\). Furthermore,

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

A convolution integral equation solved by Laplace transformations [PDF]

Journal of Computational and Applied Mathematics, 1985
The author analyzes the Volterra equation \(p(t)=\int^{t}_{0}K(t- s)p(s)ds+r(t),\) \(t\geq 0\), where K(t), r(t) grow as \(\exp (\alpha t^ 3)\), \(\alpha >0\), for \(t\to \infty\). This rapid growth excludes the straightforward use of Laplace transform techniques; instead the equation is solved using a complex independent variable.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Planar visualization of vortical flows [PDF]

, 2005
This article presents two over-looked post-processing techniques which provide the investigator with additional tools for data analysis and visualization. Both techniques exploit the trend for planar experimental data collection and are implemented in

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

FEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

Isometry property and inversion of a spherical mean Radon transform with centers on a hyperplane

AIP Advances
The spherical mean Radon transform maps a suitable function f to the integral of f over a sphere. This transform is used in photoacoustic tomography based on the wave equation.

On an integral transform [PDF]

, 1986
This paper establishes properties of a convolution type integral transform whose kernel is a Macdonald type Bessel function of zero order. An inversion formula is developed and the transform is applied to obtain the solution of some related integral ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...
