    Abstract: Background: Sepsis and septic shock are associated with enormous mortality and health care burden. Since the study of Marik et al suggested mortality benefit, there has been great interest in evaluating the role of hydrocortisone, ascorbic acid and thiamine (HAT therapy) in sepsis and septic shock. Purpose: The objective of this article is to review current literature of using HAT therapy in sepsis and septic shock, and discuss the findings in hospital mortality, change in 72 hr SOFA score, other outcomes, and the study limitations. Research Design: Three databases (PubMed, Embase, and Cochrane) were screened using predefined search terms ascorbic acid, vitamin C, thiamine, vitamin B1, hydrocortisone, sepsis, septic shock. Study Sample: Data extracted from eligible studies include authors, publication year, sample size, study design, intervention, outcome measures and study results. Each study was reviewed critically. Results: Among 11 studies included in this literature review, 3 studies reported HAT therapy was associated with mortality benefit, 1 reported hospital mortality was significantly higher in HAT group and the rest of studies didn’t reach statistical significance in mortality analysis. Significant improvement of secondary outcomes, although not consistently, were reported. Conclusions: In conclusion, HAT therapy has demonstrated a good safety profile and potential benefits in management of sepsis and septic shock. Further research is required to confirm these findings.

    Abstract: Active control of the pantograph is one of the promising measures for decreasing fluctuation in the contact force between the pantograph and the catenary. In this paper, an estimator-based multiobjective robust control strategy is proposed for an active pantograph, which consists of a state estimator and a robust H ∞ controller. The former serves as an essential tool for obtaining the states of the pantograph considering randomly missing measurements, and the latter is employed for decreasing the contact force fluctuation considering the limitation of the control force and collector uplift. Control performance is evaluated by implementing the control strategy with a nonlinear pantograph–catenary system model, in which the catenary is modeled based on nonlinear cable and truss elements. The robustness of the proposed control strategy is investigated under parameter perturbations and environmental disturbance, respectively. Furthermore, its advantage is verified by comparing it with an existing controller. Simulation results show that the control strategy can decrease the fluctuation in the contact force and reject parametric uncertainties and stochastic wind field.

    Abstract: Urban greenway is an emerging form of urban landscape offering multifaceted benefits to public health, economy, and ecology. However, the usage and user experiences of greenways are often challenging to measure because it is costly to survey such large areas. Based on the online postings from Instagram in 2017, this paper used Computer Vision (CV) technology to analyze and compare how the general public uses two typical greenway parks, The High Line in New York City and the Atlanta Beltline in Atlanta. Face and object detection analysis were conducted to infer user composition, activities, and key experiences. We presented the temporal patterns of Instagram postings as well as the group gatherings, smiling, and representative objects detected from photos. Our results have shown high user engagement levels for both parks while teens are significantly underrepresented. The High Line had more group activities and was more active during weekdays than the Atlanta Beltline. Stronger sense of escape and physical activities can be found in Atlanta Beltline. In summary, social media images like Instagram can provide strong empirical evidence for urban greenway usage when combined with artificial intelligence technologies, which can support the future practice of landscape architecture and urban design.

    Abstract: When two electric multiple units are non-electrically connected together for improving the transport capacity in high-speed railways, double pantographs frequently operate simultaneously to decrease the current capacity on a single pantograph collector. In this case, the contact force between the trailing pantograph and the catenary severely fluctuates due to the wave propagation along the catenary triggered by the leading pantograph. Therefore, this paper proposes two estimator-based H ∞ control strategies for active double-pantograph to decrease the contact force fluctuation considering the actuator time delay. To obtain the pantograph states, a robust recursive state estimation method is presented, which can effectively deal with randomly missing measurements. In addition, to overcome parametric uncertainties and non-differentiable actuator time delay, two robust multi-objective H ∞ controllers involving linear matrix inequalities are introduced according to whether the time delay can be predetermined or not. The effectiveness and robustness of the control strategies are investigated through implementing a nonlinear double-pantograph-catenary system model. Simulation results show that, for both the leading pantograph and the trailing pantograph, the proposed control strategies can decrease the contact force fluctuation with high efficiency even though the actuator time delay exists.

    Abstract: Lumbar spinal stenosis (LSS) is caused by structural changes of the spine, which lead to several severe symptoms, including back pain, leg pain, numbness and tingling in the legs, as well as reduced physical function. However, there is little evidence suggesting whether a patient with LSS should be treated with surgery. If surgery is recommended, which type of surgery benefits the patient most? To answer these questions, we will conduct a network meta-analysis and a systematic review to compare surgical and nonsurgical interventions in terms of efficacy as well as safety in adult patients with LSS. Methods and analysis: We will search the PubMed, Cochrane library, and EMBASE databases for articles published prior to October 10, 2019. We will search for randomized controlled trials assessing surgical and nonsurgical interventions for adult patients with degenerative LSS without any language restrictions. The primary outcome measures will be pain and disability. The secondary outcomes will include adverse events (number of events or number of people with each type of adverse event), reoperations, complications, blood loss and operation time. We will obtain the full texts of the potentially relevant studies and independently assess them. The quality of evidence will be evaluated according to the Grading of Recommendations Assessment, Development and Evaluation framework. A random-effects network meta-analysis will be performed to analyze all the evidence under the frequentist framework, and the ranking results will be presented. We will generate plots depicting the network geometry using Stata. The network meta-analysis will be performed according to the Bayesian framework. Ethics and dissemination Ethics approval is not required. The research will be published in a peer-reviewed journal.

    Abstract: The optimization design of a robot was usually conducted by the sequential design, which, however, neglected the interactive impacts of different disciplines. To address this shortage, this article presents a design multidisciplinary optimization procedure for a 2-degree-of-freedom robot. In the proposed design optimization, four disciplines are involved, which are composed of kinematics, dynamics, structure, and control. The coupling relationship among the four disciplines is analyzed based on variable sensitivity analysis. A collaborative optimization is proposed to obtain the optimum values of the system-level optimization. With the method of a genetic algorithm, the individual discipline optimization is executed to obtain the subsystem optimum values. The optimized 2-degree-of-freedom robot is able to synthesize an optimum function value and simultaneously shows a good satisfaction to the requirement of all constraints. The structural analysis results demonstrate that the multidisciplinary design optimization is successfully applied to the multi-degree-of-freedom robot design and provides a beneficial reference for the design of more complicated mechanical system.

    Abstract: Diabetes is a high risk factor for dementia. Employing a diabetic rat model, the present study was designed to determine whether the content of d-serine (d-Ser) in hippocampus is associated with the impairment of spatial learning and memory ability. Methods: Diabetes was induced by a single intravenous injection of streptozotocin (STZ). The insulin treatment began 3 days after STZ injection. Results: We found that both water maze learning and hippocampal CA1 long-term potentiation (LTP) were impaired in diabetic rats. The contents of glutamate, d-Ser, and serine racemase in the hippocampus of diabetic rats were significantly higher than those in the control group. Insulin treatment prevented the STZ-induced impairment in water maze learning and hippocampal CA1-LTP in diabetic rats and also maintained the contents of glutamate, d-Ser, and serine racemase at the normal range in hippocampus. Conclusions: These results suggest that insulin treatment has a potent protection effect on CA1-LTP, spatial learning and memory ability of the diabetic rats in vivo. Furthermore, insulin may take effect by inhibiting the overactivation of N-methyl-d-aspartate receptors, which play a critical role in neurotoxicity.

    Abstract: Achilles tendon rupture (ATR) incidence has increased among badminton players in recent years. The foot internal stress was hard to obtain through experimental testing. The purpose of the current research is to develop a methodology that could improve the finite element model derived foot internal stress prediction for ATR clinical and rehabilitation applications. A subject-specific musculoskeletal model was combined with a 3D finite element model to predict the metatarsal stress. The 80% point during the push-off phase of walking was selected for the comparing between injured and uninjured sides. The surgical repaired Achilles tendon (AT) after 12 months was elongated by 5.5% than the uninjured tendon. At 80% point of stance phase, the ankle plantarflexion angle and AT force decreased by 39.6% and 21.9% on the injured side, respectively. The foot inversion degree increased by 22.9% and was accompanied by the redistribution of metatarsals von Mises stress. The stresses on the fourth and fifth metatarsals were increased by 59.5% and 85.9% on the injured side. The workflow is available to assess musculoskeletal disorders and obtain foot internal stress after ATR. The decreased ankle plantar flexor force may be affected by triceps surae muscle atrophy and weakened force transmission ability of elongated AT. The increased von Mises stress on fourth and fifth metatarsals accompanied by higher foot inversion may increase the ankle lateral sprain injury risk.
