A compact 2D photonic crystal biosensor for optical detection of glioblastoma brain tissues enhanced by neural networks

Abstract In this work, a compact optical sensor based on a two-dimensional photonic crystal is proposed for detecting glioblastoma and pre-tumor brain tissues. The sensor uses a hexagonal lattice of silicon rods in air with a ring resonator structure at its center. The designed d...

Advanced experimental analysis on the synthesis and modification of zinc iron-based nanoparticles for separation and removal of pharmaceutical compounds

This study reports the visible-light-driven photocatalytic degradation of tetracycline (TC) in aqueous media using porous Co-doped ZnFe₂O₄ microspheres. ZnFe 2 O 4 (ZF) microspheres with a porous, spherical morphology were synthesized and subsequently doped with 5 wt% and 15 wt%...

Role of foundation models in data-driven tissue diagnostics

Artificial intelligence (AI)-based tissue diagnostics is entering a new phase driven by pathology foundation models: large-scale encoders and multimodal systems pretrained with self-supervised and vision–language objectives. Yet the evidence base has expanded faster than the meth...

A dynamic method to solve a solid tumor growth in a fractional model

The Residual Power Series Method (RPSM) is a semi-analytical technique used to solve nonlinear fractional differential equations.The efficiency and accuracy in approximating solutions has contributed to the popularity of this method, which has gained more attention in recent year...

Fish Epigenetics: Molecular Mechanisms, Environmental Adaptation, and Emerging Computational Approaches

Epigenetic regulation has transformed our understanding of how fish adapt to changing environments by modulating gene expression without altering the underlying DNA sequence. This review explores the “dark mastery” of fish epigenetics by providing mechanistic insights into the pr...

Enhancing PMSM Drive Performance Under Open-Phase Fault Using Fractional-Order Controllers

Open-phase faults (OPFs) represent a major challenge in PMSM drive systems due to the induced current imbalance, torque ripple, and degradation in speed regulation performance. Although fractional-order controllers and model predictive control have been extensively investigated f...

Intelligent predictive neural network analysis on microbes in bioconvection flow of hybrid nanoliquid under diffusion thermo and thermo diffusion effects

The model optimizes microfluidic and lab-on-a-chip systems by predicting gyrotactic microbe-driven mixing and transport in the presence of linked thermal and concentration gradients. It aids in the design and operation of bioreactors and wastewater treatment units by simulating m...

Delving into carbon dioxide frosting temperature in natural gas mixtures using hyperparameter optimized gradient boosting decision trees

Predicting carbon dioxide frosting temperature within natural gas mixture is critical to prevent costly and hazardous blockages in cryogenic processing facilities. The research develops an accurate and thermodynamically interpretable machine learning model to precisely forecast t...

Sero-epidemiological survey of Toxoplasma gondii in water buffalo (Bubalus bubalis) and domestic pig (Sus scrofa domesticus) across upper and lower Egypt

Toxoplasma gondii ( T. gondii ) is a globally prevalent protozoan parasite affecting warm-blooded species, including humans. In Egypt, serological surveys have been conducted in several livestock; however, studies on species such as buffalo and pigs remain scarce. This study aime...

A Systematic Multi-Dataset, Multi-Seed Evaluation of Preprocessing Strategies for Retinal Optic Disc and Cup Segmentation

Background/Objectives: Accurate delineation of the optic disc and optic cup in retinal fundus photographs is a prerequisite for automated glaucoma screening. While encoder–decoder segmentation models have advanced considerably, the contribution of upstream preprocessing to segmen...

Binclean: Sanitizing Disassemblies to Improve Malware Recognition
