Coupling biplanar videoradiography with the unified deformable power model to quantify foot and talocrural joint power.

Department of Mechanical and Materials Engineering, Queen's University, Kingston, Canada. Electronic address:
Analysis of the power produced by the foot and ankle during locomotion can provide insights into their function. Foot power is often quantified by applying the unified deformable (UD) power model to the hindfoot while ankle power is quantified by performing three or six degree-of-freedom joint power calculations. These measurements are possible with optical motion capture.

HfO/ZrO-based ferroelectrics present tremendous potential for next-generation non-volatile memory due to their high scalability and compatibility with silicon technology. Unlike the continuous polar layers in perovskite ferroelectrics, HfO/ZrO-based ferroelectrics are composed of alternating polar layers with oxygen shifts and non-polar spacers, which leads to a distinct ferroelectric switching mechanism. However, directly observing the switching process has been a big challenge due to the polymorph feature of nanoscale fluorites and the difficulty in in situ imaging on light elements.

Citrullus lanatus is an important vegetable crop, but it is heavily polluted by cadmium. In this study, we used C. Lanatus as experimental material to investigate effects of different concentrations (0, 50, 100, 200, 400 µmolL) of exogenous melatonin, and grafting on the physiological growth index and anatomical structure of seedlings were studied by simulating Cd (180 mg L) stress environment.

Department of Orthopaedic Surgery, Wuxi Ninth People's Hospital Affiliated to Soochow University, Wuxi, Jiangsu, China.
Background: The paratenon has been shown to promote Achilles tendon healing, but the evidence supporting the role of paratenon protection technique in Achilles tendon repair is sparse. We retrospectively assessed the results of a paratenon-sparing repair technique vs an open giftbox repair of Achilles tendon ruptures.
Methods: Patients with Achilles tendon rupture who underwent surgical treatment at our hospital between January 2015 and August 2021 were retrospectively reviewed.
Angular dependence of random laser emission by using ZnO-CuO heterostructure as scatterer and its applications in biocompatible imaging.

The angular dependence of random laser (RL) generation in a commercially available rhodamine 6G (Rh6G) dye has been demonstrated using ZnO-CuO heterostructure as passive scatterers. The grass-like superstructure formed at a 1M:1M molar ratio of ZnO-CuO significantly enhances scattering, resulting in RL spikes with a full width at half maximum (FWHM) of just a few nanometer and a noticeable reduction in the RL threshold. RL emission spectra were collected over an angular spread of 0-180 degrees, revealing a remarkable shift in RL emission from 566 nm to 580 nm.
