Recent studies have indicated a close relationship between intracranial arterial stenosis and white matter hyperintensities (WMHs), but few reported on the correlation characteristics of wall plaques WMHs. The aim this study was to comprehensively assess atherosclerosis WMHs using 3.0T high-resolution magnetic resonance imaging (HR-MRI). Ninety-two ischemic stroke patients with middle cerebral artery (MCA) <50% cranial angiography (MRA) underwent conventional MRI HR-MRI examinations....

This research delves into the effectiveness of various exercise therapies for Chronic Ankle Instability (CAI), a condition that frequently develops when initial ankle sprains are not adequately treated. CAI is characterized by repetitive sprains, joint instability, and reduced mobility, which can severely impact an individual's daily activities sports performance. Different methods rehabilitation, including muscle strengthening exercises, proprioceptive training, balance improvement, were...

Event cameras draw inspiration from biological systems, boasting low latency and high dynamic range while consuming minimal power. The most current approach to processing Cloud often involves converting it into frame-based representations, which neglects the sparsity of events, loses fine-grained temporal information, increases computational burden. In contrast, Point is a popular representation for 3-dimensional data serves as an alternative method exploit local global spatial features....

Compute-in-memory (CIM) based on emerging nonvolatile memory (eNVM) is an effective way to deploy neural networks low-power edge devices for both storage and computation. NVMs such as ReRAM have been widely used in CIM. Meanwhile, MRAM has higher read write cycles, lower device cycle variation a bit error rate, making it equally attractive storage. However, the high current low on/off ratio result large energy consumption limiting its large-scale application The spiking network (SNN)...

Event cameras have gained popularity in computer vision due to their data sparsity, high dynamic range, and low latency. As a bio-inspired sensor, event generate sparse asynchronous data, which is inherently incompatible with the traditional frame-based method. Alternatively, point-based method can avoid additional modality transformation naturally adapt sparsity of events. Still, it typically cannot reach comparable accuracy as We propose lightweight generalized point cloud network called...

Power consumption has become the major concern in neural network accelerators for edge devices. The novel non-volatile-memory (NVM) based computing-in-memory (CIM) architecture shown great potential better energy efficiency. However, most of recent NVM-CIM solutions mainly focus on fixed-point calculation and are not applicable to floating-point (FP) processing. In this paper, we propose an analog-domain CIM (AFPR-CIM) resistive random-access memory (RRAM). A adaptive dynamic-range FP-ADC is...

Event cameras are biologically inspired sensors that emit events asynchronously with remarkable temporal resolution, garnering significant attention from both industry and academia. Mainstream methods favor frame voxel representations, which reach a satisfactory performance while introducing time-consuming transformation, bulky models, sacrificing fine-grained information. Alternatively, Point Cloud representation demonstrates promise in addressing the mentioned weaknesses, but it ignores...
