Group theoretic thermal analysis (GTTA) of Powell-Eyring fluid flow with Identical free stream (FS) and heated stretched porous (HSP) boundaries: AI Decisions

Case Studies in Thermal Engineering
Artificial intelligence (AI) is used to study the thermal flow field for Powell-Eyring fluid model when free stream condition is the same as stretching at the surface. The temperature and concentration flow aspects are considered simultaneously.

Planar undulator motion excited by a fixed traveling wave: Quasiperiodic averaging, normal forms, and the free electron laser pendulum

Physical Review Special Topics. Accelerators and Beams, 2013
We present a mathematical analysis of planar motion of energetic electrons moving through a planar dipole undulator, excited by a fixed planar polarized plane wave Maxwell field in the x-ray free electron laser (FEL) regime.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Robust zero-watermarking for color images using hybrid deep learning models and encryption

Scientific Reports
Reliable zero-watermarking is a distortion-free approach to copyright protection, which has been a primary focus of digital watermarking research. Traditional zero-watermarking techniques often struggle to maintain resilience against geometric and signal

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

k-dimensional error-free deconvolution using the fermat number transform

Computers & Mathematics with Applications, 1989
AbstractThe paper presents the generalization of the one-dimensional deconvolution algorithm using the Fermat number transform for the k-dimensional deconvolution. The problems of how to express a k-dimensional convolution system in the form of special matrix equation, how to calculate the precise value of the matrix determinant and how to remove ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Self-Supervised Learning for Precise Individual Tree Segmentation in Airborne LiDAR Point Clouds

IEEE Access
Segmenting individual trees from airborne LiDAR point cloud data is critical for forest management, urban planning, and ecological monitoring but remains challenging due to complex natural environments, diverse tree architectures, and dense canopies ...
