A Platform for the Actuation of Magnetically Labeled Skeletal Muscle Cells Using Dynamic Magnetic Stimulation

Small, EarlyView.
A magnetic stimulation platform for the remote stimulation of cells is presented, consisting of a magnetic stimulator and magnetic microspheres. Skeletal muscle cells are labeled with magnetic microspheres, which act as local magnetic actuators on the cells upon application of the magnetic field.

Toward the Application of Multiaxial Failure Criteria: Mean Stress Sensitivity of Carbide‐Rich, High‐Alloy PM‐HIP Tool Steels Under Axial and Torsional Cyclic Loading

steel research international, EarlyView.
This study quantifies axial and torsional long‐life fatigue (LLF) behavior of three carbide‐rich PM‐HIP tool steels, correlating LLF strength with intrinsic defect size and cleanliness, thereby extracting material‐specific mean stress sensitivities and Haigh diagrams.

Influence of shear reinforcement detailing on the shear capacity of reinforced concrete beams

Structural Concrete, EarlyView.
Abstract Alternative shear reinforcement layouts that do not fully enclose the longitudinal tensile reinforcement can significantly improve the constructability of reinforced concrete (RC) members. However, their influence on shear transfer mechanisms is not yet fully understood. To address this gap, an experimental program comprising 10 shear tests on

A Preventive Static Security Control Strategy for Distribution Networks Based on Phase Shifting Transformer Loop‐Closing Devices

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
As the share of renewable energy in the energy mix continues to increase, the penetration of distributed renewable generation in distribution networks is also rising steadily. Loop‐closing operation provides an effective means to enhance renewable energy accommodation across different grid partitions.

Juvenile and Pubertal Exposure to Polystyrene Nanoplastics Impairs Epididymal Structure and Sperm Quality in Mice

Environmental Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are emerging environmental contaminants capable of crossing biological barriers, accumulating in tissues, and disrupting physiological pathways. The male reproductive system is particularly vulnerable during the postnatal period, a developmental window characterized by intense testicular differentiation and epididymal ...

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

Environmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

Wildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

A secured cloud‐medical data sharing with A‐BRSA and Salp ‐Ant Lion Optimisation Algorithm

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Sharing medical data among healthcare providers, researchers, and patients is crucial for efficient healthcare services. Cloud‐assisted smart healthcare (s‐healthcare) systems have made it easier to store EHRs effectively. However, the traditional encryption algorithms used to secure this data can be vulnerable to attacks if the encryption key
