The human brain is a complex spiking neural network (SNN) capable of learning multimodal signals in a zero-shot manner by generalizing existing knowledge. Remarkably, it maintains minimal power consumption through event-based signal propagation. However, replicating the human brain in neuromorphic hardware presents both hardware and software challenges.

Case: The effective reconstruction and functional restoration of the shoulder joint after surgical treatment of shoulder girdle tumors, especially those involving resection of the glenoid, poses significant challenges. Reconstruction methods include allograft reconstruction and shoulder prosthesis. In this report, we present 2 cases of scapulectomy for tumors involving the glenoid, followed by shoulder reconstruction using custom-designed reverse shoulder prostheses that are partially fixed to the clavicle.

Background: Wearable sensor technology shows promise for neuropsychiatric symptoms (NPS) identification/monitoring in persons living with dementia (PLWD). Accelerometry measures acceleration of body segments and physical activity. This study explores the diagnostic test accuracy (DTA) of accelerometry to identify the following 6 NPS associated with motor activity: aberrant motor behavior (AMB), aggression, agitation, anxiety, apathy, and wandering.

January 2025
Mayo Clinic Arizona Department of Orthopedic Surgery, Phoenix, Arizona, USA.
Background: The Latarjet and other bony augmentation procedures are commonly used to treat anterior shoulder instability in the setting of significant glenoid bone loss. Although several fixation strategies have been reported, the biomechanical strength of these techniques remains poorly understood.
Purpose: To perform a systematic review of the biomechanical strength of glenoid bony augmentation procedures for anterior shoulder instability.
Electrostatic in-plane structural superlubric actuator.
Nat Commun
January 2025
Tsinghua Shenzhen International Graduate School, Tsinghua University, Shenzhen, China.
Micro actuators are widely used in NEMS/MEMS for control and sensing. However, most are designed with suspended beams anchored at fixed points, causing two main issues: restricted actuated stroke and movement modes, and reduced lifespan due to fatigue from repeated beam deformation, contact wear and stiction. Here, we develop an electrostatic in-plane actuator leveraging structural superlubric sliding interfaces, characterized by zero wear, ultralow friction, and no fixed anchor.
