Overcoming spectral limits of perovskite photodetectors for the infrared region

open access: yesInfoScience, EarlyView.
Infrared (IR) photodetectors are vital for modern optoelectronics, but traditional inorganic semiconductors face limitations in cost, processing, and bandgap tunability. This review provides a summary of advanced strategies to extend metal halide perovskites into the IR region, categorizing approaches into intrinsic material engineering, physical ...

Joint Optimal Allocation of Resources for Multiple Jammer Based on Multi‐Agent Deep Reinforcement Learning

open access: yesIET Radar, Sonar & Navigation
In response to the complex scenario where multiple jammers navigate through a netted radar system (NRS), this study presents an optimised allocation algorithm for cooperative jamming resources, namely the Multi‐Agent Jamming Resource Allocation (MJCJRA ...

Diffusion MRI‐Based Fetal Thermometry Using Cerebrospinal Fluid: A Translational Feasibility Study

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Noninvasive fetal temperature assessment could improve MRI safety monitoring and provide insight into fetal physiology. Diffusion MRI is a potential approach because water diffusivity in free fluids is temperature dependent. However, the applicability of adult‐derived diffusivity–temperature calibration to neonatal and fetal CSF ...

Stretch‐shortening cycle force–time and power–time waveform analysis indicates limitations of the contralateral limb benchmark in athletes with ACL injury

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Unilateral countermovement jump (CMJsingle) testing is commonly used after anterior cruciate ligament reconstruction (ACLR) to assess stretch‐shortening cycle (SSC) function and return‐to‐sport readiness. However, the impact of ACLR on contralateral limb SSC function is poorly understood, which may impact the utility of the ...

Detection of previous knee injuries using lower limb‐worn inertial measurement units: A cross‐sectional machine‐learning study

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Previous knee injury increases the risk of subsequent injury, even after functional recovery, yet residual gait, running or load alterations often go undetected in routine assessment. Wearable inertial measurement units (IMUs) may enable scalable detection of such alterations outside laboratory settings.

Room‐Temperature Polariton Condensation Into Superscar Modes in Growth‐Defined Triangular Micro‐Prism Resonators

open access: yesLaser &Photonics Reviews, EarlyView.
High‐Q superscar modes in growth‐defined triangular GaN micro‐prism resonators enable strong exciton–photon coupling and room‐temperature polariton condensation, offering a scalable platform for integrated III‐nitride polariton devices. ABSTRACT Group III‐nitride semiconductors are regarded as key materials for realizing polariton devices operating at ...

Conjugation‐Length Dependent Interplay Between Charge Transfer and Locally Excited States in Sequence‐Defined Donor–Acceptor Substituted Oligo(Phenylene Ethynylene)s

open access: yesMacromolecular Rapid Communications, EarlyView.
Iterative synthesis gives access to sequence‐defined oligo(para‐phenylene ethynylene)s, bridging donor and acceptor units through stepwise extension of the conjugated backbone. Accurate length control enables systematic structure‐property relationship investigations across absorption, emission, and excited‐state dynamics.

Data‐Driven Insights into Hyperkinetic Disorders in Neurodevelopmental Syndromes and Epileptic Encephalopathies

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Childhood‐onset hyperkinetic movement disorders occur in a range of genetic conditions. Recently, there has been an increase in recognition of hyperkinetic movement disorders, mainly dystonia, chorea and dyskinesia, with monogenic conditions associated with neurodevelopmental delay (NDD) and also with developmental and epileptic ...
