Hybrid GRA–Machine Learning Framework for Surface and Performance Optimization of Ti49.3Ni50.7 SMA in Biomedical Applications

Engineering Reports, Volume 8, Issue 4, April 2026.
Ti49.3Ni50.7 shape memory alloy is highly biocompatible but difficult to machine due to its complex thermo‐mechanical behavior. An enhanced Wire EDM process was developed using a Taguchi L18 design, GRA, and Random Forest with Bayesian optimization. The optimized parameters achieved a surface roughness of 1.298 μm and a material removal rate of 2.537 ...

Muscle Weakness and the Irisin–BDNF and Oxidative Stress Axis in the 60‐Day Pseudorandomised Controlled AGBRESA Bed Rest Study

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 2, April 2026.
ABSTRACT Background Muscle atrophy and weakness are among the most detrimental consequences of disuse, microgravity, hospitalisation and ageing. Oxidative modifications of myofibrillar proteins generated by oxidative stress may contribute to the reduced force‐ and power‐generating capacity of skeletal muscles. As part of the 60‐day AGBRESA bed rest (BR)

Using Machine Learning to Uncover Ecological Mechanisms Controlling Abundance of Phytoplankton Size Classes From Large‐Scale Observations

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Phytoplankton size classes (PSCs) and Phytoplankton functional types (PFTs) determine many fundamental biogeochemical processes including nutrient uptake, energy transfer through marine food webs, ocean carbon export, and gas exchange with the atmosphere. Discerning the causes of spatio‐temporal variability of PSCs is a scientific priority for

An Intelligent Reconfigurable Graphene–VO2 Hybrid Terahertz Bandpass Filter Architecture for Differential Biomolecular Sensing and Machine Learning–Driven Analyte Characterization

International Journal of Optics, Volume 2026, Issue 1, 2026.
A compact hybrid graphene–VO2 terahertz (THz) bandpass filter integrating reconfigurable operation, differential biosensing, and machine learning (ML)–based prediction is proposed and numerically investigated. The device consists of a symmetric dual‐stepped‐impedance resonator (SIR) fabricated on a quartz/silicon substrate, where graphene provides ...

Disentangling complex relationships and disjunctions in western Camassia: Integrating multiple criteria to resolve taxonomic boundaries

American Journal of Botany, Volume 112, Issue 12, December 2025.
Abstract Premise Understanding genetic and morphological variability helps efforts to sustain landscapes and develop effective species concepts for resolving difficult groups. To unravel puzzling relationships and range disjunctions, we applied morphometrics, phenology, phylogenetics and population genetics in Camassia species with cultural, ecological,

Current progress of digital twin construction using medical imaging

Journal of Applied Clinical Medical Physics, Volume 26, Issue 9, September 2025.
Abstract Medical imaging is fundamental to digital twin technology, enabling patient‐specific virtual models of anatomy and physiology. By integrating high‐resolution modalities (Magnetic Resonance Imaging (MRI), Computed Tomography (CT), Positron Emission Tomography (PET), ultrasound) with computational frameworks, recent imaging advances now support ...

Hydrated Silica in Oxia Planum, Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Hydrated silica (SiO2·nH2O; opal) is important for understanding the geological and aqueous history and habitability of Mars, owing to its genesis in a wide range of aqueous environments and its high biosignature preservation potential relative to other hydrated minerals.

Association of Changes in Hand Pain With BMI, Employment, and Mental Well‐Being Over Four Years in Patients With Hand Osteoarthritis

Arthritis Care &Research, Volume 77, Issue 5, Page 614-622, May 2025.
Objective We aimed to characterize patients with hand osteoarthritis (OA) with deteriorating or improving hand pain and to investigate patients achieving good clinical outcome after four years. Methods We used four‐year annual Australian/Canadian Hand Osteoarthritis Index (AUSCAN) pain subscale (range 0–20) measurements from the Hand OSTeoArthritis in ...
