Aims: This cross-sectional study aimed to investigate the in vivo ankle kinetic alterations in patients with concomitant chronic ankle instability (CAI) and osteochondral lesion of the talus (OLT), which may offer opportunities for clinician intervention in treatment and rehabilitation.
Methods: A total of 16 subjects with CAI (eight without OLT and eight with OLT) and eight healthy subjects underwent gait analysis in a stair descent setting. Inverse dynamic analysis was applied to ground reaction forces and marker trajectories using the AnyBody Modeling System.
Article Synopsis
- Current research on gait dynamics mostly examines how the body's center of mass reacts to disruptions during treadmill walking, but there is limited understanding of how these perturbations affect hip joint coordination in overground walking.
- A specialized device was used in this study to apply controlled lateral forces to participants' pelvises while they walked, and the resulting biomechanical responses were analyzed through neuromusculoskeletal models and surface electromyographic data.
- The study found significant changes in hip motion and kinetics after perturbations, indicating a coordinated strategy for balancing during gait disruptions, with implications for how muscle activation can affect foot placement and joint stability in response to external forces.
Background: This study aims to assess the mechanical and functional effects of the arthroscopic modified Broström procedure (AMBP) on patients with lateral ankle instability.
Methods: Eight patients with unilateral ankle instability treated with AMBP and eight healthy subjects were recruited. Healthy subjects, preoperative and one-year postoperative patients were assessed using outcome scales and the Star Excursion Balance Test (SEBT) for dynamic postural control.
Using the characteristics of low rank for reverberation and sparsity for the target echo in multi-ping detection, the low-rank and sparsity decomposition method can effectively reduce reverberation. However, in the case of highly sparse reverberation or a stationary target, the distinctions in the characteristics between the reverberation and target echo become ambiguous. As a result, the reverberation reduction performance is degraded.

However, a large number of optical elements used in optical networks-on-chip (ONoCs) generate high transmission loss which will influence network performance severely and increase power consumption. In this paper, the Dijkstra algorithm is adopted to realize adaptive routing with minimum transmission loss of link and reduce the output power of the link transmitter in mesh-based ONoCs.

Article Synopsis
- Optical networks-on-chips (ONoCs) offer high bandwidth and low latency for on-chip communication, but power loss and optical signal-to-noise ratio (OSNR) are critical challenges affecting their scalability and performance.
- The current dimension-order routing algorithm used in ONoCs results in significant power loss and crosstalk noise, prompting the need for improved routing methods.
- This paper introduces a 5×5 all-pass optical router model and a novel routing algorithm that minimizes power loss while optimizing OSNR, demonstrating successful results in reducing power loss and enhancing OSNR in larger network sizes (5×5 and 6×6).
Reverberation reduction based on multi-ping association in a moving target scenario.
J Acoust Soc Am
October 2020
Conventional reverberation reduction methods are conducted with single-ping data and may fail in a low signal-to-reverberation ratio (SRR) environment. To improve the performance of reverberation reduction, multi-ping data are fully considered in this paper. The reverberation can be treated as a combination of the steady component of reverberation and reverberation fluctuations, and then an alternating direction multiplier method is proposed to reduce the steady component of the reverberation.

Objective: To investigate the effects of Shiquanyuzhentang (Traditional Chinese Medicine) on the immunologic function of tu-mor-bearing mice and its mechanism of antitumor.
Methods: Thirty SPF grade male Kunming mice transplanted with H hepatocellular carci-noma were divided into three groups randomly:model group,positive control group and Shiquanyuzhentang group(=10). Another 10 mice were selected as normal control group.
