Spiking frequency adaptability and multi-weight synergy in artificial neuronal modules bifunctional NbO memristors.

To address the limitations of current artificial neurons in neuromorphic hardware implementation, NbO-based bifunctional memristors are fabricated to construct oscillatory units and advanced neuronal modules. NbObased memristors operate as either threshold-switching memristors (TSMs) or dynamic memristors (DyMs), depending on whether electroforming is applied. TSMs are employed to build oscillatory units and further reconfigured into a weighted multi-terminal neuronal module, enabling real-time spatiotemporal summation of input spikes based on the leaky integrate-and-fire model.

Revision rate after surgery for elbow osteochondritis dissecans: a systemic review.

Background: Humeral capitellum osteochondritis dissecans (OCD) is a common condition among overhead throwing athletes and is typically treated surgically. While stable lesions can be treated nonoperatively, untreated unstable lesions can lead to significant elbow discomfort and impaired quality of life. This study reviews the revision rate and interval in athletes with elbow OCD following primary surgery.

Endoscopic Interlaminar Standalone Decompression for Lumbar Lateral Recess Stenosis With Subligamentous Disc Herniation: A Disc-Preserving Alternative to Discectomy.

Objective: Lumbar lateral recess stenosis (LRS) with subligamentous disc herniation often causes debilitating radicular pain. While discectomy is commonly performed, it risks disc degeneration and spinal instability. This study aimed to evaluate the clinical and radiographic outcomes of full-endoscopic interlaminar standalone decompression as a minimally invasive, disc-preserving alternative to discectomy for treating single-level LRS with subligamentous disc herniation.

Organization and structure of intensive care management of adult congenital heart disease in the United States.

Background: The growing number of adults with congenital heart disease has led to the formation of dedicated centers to provide specialized care. There is a paucity of published data on the organization, staffing, and resources available when adult congenital heart disease (ACHD) patients are hospitalized in intensive care settings. This study aims to describe the delivery of intensive care for ACHD patients in the United States and identify key differences between accredited centers or those pending accreditation and non-accredited Adult Congenital Heart Association (ACHA) centers.

Injectable Estradiol Dosing Regimens in Transgender and Nonbinary Adults Listed as Male at Birth.

Context: Many transgender and nonbinary (TGNB) individuals assigned male at birth (AMAB) seek hormone therapy to achieve physical and emotional changes.

Motion image recognition is a critical component of internet of things (IoT) applications, necessitating advanced processing techniques for spatiotemporal data. Conventional feedforward neural networks (FNNs) often fail to effectively capture temporal dependencies.

Re-evaluating surgical treatment protocol for unstable proximal humerus fractures: emphasizing soft tissue preservation via minimally invasive approach over structural allograft augmentation in deltopectoral approach. A single-center retrospective study.

Background: Managing unstable proximal humerus fractures (PHFs), particularly in elderly patients, is challenging due to the need to balance stability with minimizing surgical trauma. The conventional deltopectoral (DP) approach with structural allograft for medial support is widely used but can involve significant soft tissue disruption. This study compares clinical and radiographic outcomes between a minimally invasive deltoid-split (MIS-DS) approach without allograft and the traditional DP approach with allograft.

This study investigates the use of dynamic memristors Ta/IGZO/TaO/Pt combined with peripheral circuits to emulate the leaky integrate-and-fire behavior of neurons, focusing on incorporating a refractory period. The refractory period is crucial as it prevents neurons from becoming overactive and ensures precise timing in signal processing.

Does the utilization of fluoroscopy affect the accuracy of prosthesis position in patients undergoing hip replacement surgery via the direct anterior approach compared to the posterolateral approach for an experienced surgeon? A single-center retrospective study.

Background: The direct anterior approach (DAA) for total hip arthroplasty (THA) has gained popularity due to perceived advantages in achieving better early outcomes. However, the theoretical benefits such as precise implant positioning and accurate leg length restoration are still inconsistent. In this study, we compared implant position and leg length discrepancy (LLD) of the DAA and posterolateral approach (PLA) conducted by a single surgeon who had mastered both approaches.

Repulsion, Acceleration, and Coalescence between Water Droplets on Superhydrophobic Glass by Triboelectrification.

Manipulating the motion of water droplets on surfaces, which is crucial for various applications, such as microfluidics and heat transfer, presents considerable challenges, primarily due to the significant influence of capillary forces. This effect becomes more pronounced when droplets are in close proximity, often resulting in undesired coalescence. Triboelectrification, which involves charging pure water droplets, is a promising approach to enhance the ability to manipulate water droplets.

Unlike isolable tin(II) hydrides supported by bulky ligands reported in the literature, this research describes the synthesis and characterization of thermally stable tin(II) hydrides () and () stabilized by sterically undemanding N,N,N-coordinating pincer-type ligands ( = 2,5-dipyridyl-3,4-diphenylpyrrolato; = 2,5-bis(6-methylpyridyl)pyrrolato).
