Polydopamine Nanoparticle‐Mediated Precise Near‐Infrared Optical Stimulation for Cognitive Enhancement

open access: yesAdvanced Science, EarlyView.
Polydopamine nanoparticles enable a precise, non‐genetic, and transcranial neuromodulation strategy via near‐infrared photothermal stimulation. By activating TRPV1 channels, this approach specifically enhances hippocampal gamma oscillations, thereby rescuing spatial memory deficits in models of perioperative neurocognitive disorder.

Posterolateral corner reconstruction using hamstrings grafts—A comparative biomechanical study of three techniques

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare three posterolateral corner (PLC) reconstruction techniques—the popliteofibular loop (PFLoop), the modified LaPrade (LP) and modified Arciero (AR) techniques—in restoring knee laxity in varus (VR), external tibial rotation (ER) and posterior tibial translation (PTT). Methods Nine cadaveric knees were subjected to 8Nm VR, 5Nm

Design and Development of a Modular Ballistic Pendulum for High‐Impulse Measurement in Contact and Near‐Field Explosive Loading

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measuring impulse from explosive charges in contact and near‐field configurations presents practical challenges due to wide variation in impulse magnitude. Ballistic pendula are widely used for impulse measurement, but many existing designs are limited to narrow operating envelopes or are poorly suited to repeated contact testing and tamped ...

Study on the Coupled Effects of High‐Speed Airflow and Charged Sand on Power‐Frequency Discharge Characteristics of Conductor–Tower Gaps in Strong Wind–Sand Environments

open access: yesHigh Voltage, EarlyView.
ABSTRACT Strong wind–sand weather in Xinjiang threatens power grid safety by increasing transmission line tripping risks. Existing studies focus on sand polarization but neglect the coupled influence of high‐speed airflow and charged sand on gap discharge characteristics.

Patient Safety and Organisational Accountability: Reassessing Criminal Liability Frameworks in Healthcare

open access: yesThe Modern Law Review, EarlyView.
Serious harm in healthcare often results from systemic failures, yet criminal accountability remains largely addressed through homicide law, gross negligence manslaughter and health‐and‐safety offences, frameworks that emphasise individual culpability and are ill‐suited to addressing organisational failings.

‘Sinister Indian‐like Half‐circle’: Tennis, Orientalism and the White Racial Frame in the Twentieth‐Century British Sporting Press

open access: yesHistory, EarlyView.
Abstract Examining sport alongside race, media and imperial power opens a rich field for understanding how macro‐level ideologies are shaped and circulated through everyday cultural forms. In twentieth‐century Britain, mass media framed and distributed narratives that rendered the empire's political realities intelligible to a broad public.
