Grid Independence Study and a Finite Difference Collocation Approach for Magnetized CeO2‐Ti3C2/H2O Hybrid Nanofluid Flow Over an Inclined Spinning Disk With Newtonian Heating

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This work examines magnetohydrodynamic (CeO2, Ti3C2/H2O) hybrid nanofluid (HNF) flow on an inclined revolving disk with effects of Newtonian heating. HNF is obtained by suspending the nanoparticles (NPs) of CeO2 and Ti3C2 in water (H2O). The flow is affected by mixed convection, Joule heating, nonlinear thermally radiative and dissipative ...

First‐Principles Study of Structural, Mechanical, Electronic, Thermodynamical, and Optical Properties of XGaO2 (X = Rb and Cs): Unlocking Its Green Energy Potential

Advanced Physics Research, EarlyView.
This study employs density functional theory (DFT) to investigate the structural, mechanical, electronic, optical, and thermodynamic properties of RbGaO2 and CsGaO2. The calculated band structures and band‐edge positions indicate semiconducting behavior and favorable alignment for photocatalytic dye degradation and hydrogen evolution, highlighting ...

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

The Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

A Mouse Model of Depression‐Tumor Multimorbidity Reveals the Mechanism of Tumor Growth Accelerated by Depression

Animal Research and One Health, EarlyView.
Depression accelerates tumor growth by dysregulation of tumor immune microenvironment. (A) Modeling methods: Subcutaneous tumor models were established under chronic unpredictable mild stress conditions, including cold swimming, physical restraint, and food/water deprivation, leading to increased tumor growth.

Arthroscopic Repair of the Anterior Root of the Lateral Meniscus Using Knotless All‐Suture Anchors

Arthroscopy Techniques, EarlyView.
Abstract Anterior root tears of the lateral meniscus are uncommon but can significantly disrupt knee biomechanics by increasing contact pressures and accelerating cartilage degeneration if left untreated. This article describes an arthroscopic technique for repair of the anterior root of the lateral meniscus using all‐suture anchors.
