Skin integrity breakdown and pressure ulcer formation on the heel are predictable and preventable healthcare occurrences. By minimizing surface contact pressures that can cause heel capillary occlusion, heel off-loading devices help mitigate the risk of decubitus ulceration. The purpose of this study is to investigate the efficacy of six off-loading methods commonly used in clinical settings to decrease heel contact pressure. Pressure mapping is used to evaluate contact pressure at the heel for underweight, normal weight, and overweight simulations. Based upon averages across four trials, it is shown that all devices reduce heel contact pressure when compared to no off-load- ing. The PRUventor™ boot exhibits significantly lower average pressure values than other off-load- ing strategies tested, suggesting that the PRUventor™ is the most effective off-loading device. From the analysis of the experimental data and comparison to similar data for respective off-loading alternatives, it is concluded that the PRUventor™ boot is an effective heel off-loading device for use in clinical settings.

Robot locomotion is an active research area. In this paper we focus on the locomotion of quadruped robots. An effective walking gait of quadruped robots is mainly concerned with two key aspects, namely speed and stability. The large search space of potential parameter settings for leg joints means that hand tuning is not feasible in general. As a result walking parameters are typically determined using machine learning techniques. A major shortcoming of using machine learning techniques is the significant wear and tear of robots since many parameter combinations need to be evaluated before an optimal solution is found. This paper proposes a direct walking gait learning approach, which is specifically designed to reduce wear and tear of robot motors, joints and other hardware. In essence we provide an effective learning mechanism that leads to a solution in a faster convergence time than previous algorithms. The results demonstrate that the new learning algorithm obtains a faster convergence to the best solutions in a short run. This approach is significant in obtaining faster walking gaits which will be useful for a wide range of applications where speed and stability are important. Future work will extend our methods so that the faster convergence algorithm can be applied to a two legged humanoid and lead to less wear and tear whilst still developing a fast and stable gait.

采用原位还原技术制备出以单壁碳纳米管、炭黑(P90)和TiO_2为支撑的3种金纳米复合材料,并通过多种表征手段来探讨物理性能。再将他们作为1-苯基乙醇、2-苯基乙醇和苯甲醇的绿色需氧氧化杂化催化剂来测试稳定性。在所有反应中,与P90和TiO_2相比,以单壁碳纳米管作支撑的金纳米杂化催化剂呈现出最优的反应效率和特异性。这些金纳米杂化催化剂经多次反应循环后反应活性衰减很小,从而能被重复使用。同时探讨了金纳米杂化催化剂活性高的原因,包括颗粒形貌、尺寸和支撑体性能。可以推断,基底上功能团迁移的位置、支撑材料的性质和活性金纳米颗粒相的颗粒尺寸分布均有助于使这些催化剂在反应中显示出高的选择性。

Emerging research has suggested that inflammatory stress may play a role in the development of *** the leptin and insulin receptor are sensitive to intracellular inflammatory signaling that can be stimulated through toll-like receptor 4 activation by saturated fat. Pharmacological intervention within this cascade often protects animals from becoming obese, thus highlighting inflammatory pathways as a possible site of study in the prevention of pathologic weight gain. It has been well established in animal models that females display a marked reduction in the susceptibility to weight gain on high-fat diets compared to males. In addition, it has been widely accepted that females are partially protected from inflammatory-related diseases. At the molecular level, this reduction in disease susceptibility has been suggested to be due to the anti-inflammatory properties of 17 β-estradiol. Through direct free radical scavenging, transcriptional regulation, and protein interactions, chronic exposure to estradiol can reduce systemic inflammatory stress. As the knowledge base continues to grow on the etiology of obesity, further research is needed on the precise molecular pathways that can be inhibited by estradiol. Understanding of such pathways may provide a basis for the future use of estrogen and its related compounds （daidzein, genistein, resveratrol） to prevent weight gain in peri- and post-menopausal females.
