Supercapacitors(SCs) are high-power energy storage devices with ultra-fast charge/discharge *** using concentrated aqueous-based electrolytes can work at low temperatures due to their intrinsic properties, such as higher freezing point depression(FPD) and robustness. Besides the traditional organic-and aqueous-based(salt-in-water) electrolytes used in SCs, water-in-salt(WISE) sodium perchlorate electrolytes offer high FPD, non-flammability, and low-toxicity conditions, allowing the fabrication of safer, environmentally friendly, and more robust devices. For the first time, this work reports a comprehensive study regarding WISE system’s charge-storage capabilities and physicochemical properties under low-temperature conditions(T < 0 ℃) using mesoporous carbon-based electrodes. The effect of temperature reduction on the electrolyte viscosity and electrical properties was investigated using different techniques and the in-situ(or operando) Raman spectroscopy under dynamic polarization *** cell voltage, equivalent series resistance, and specific capacitance were investigated as a function of the temperature. The cell voltage(U) increased ~ 50%, while the specific capacitance decreased ~20%when the temperature was reduced from 25 ℃ to -10 ℃. As a result, the maximum specific energy(E = CU^(2)/2) increased ~ 100%. Therefore, low-temperature WISEs are promising candidates to improve the energy-storage characteristics in SCs.

Nowadays, fracture surgery represents a big part of the orthopedic surgeon workload, and usually has associated major clinical and social cost implications. These fractures have several complications. Some of these are medical, and other related to the surgical treatment itself. Medical complications may affect around 20% of patients with hip fracture. Cognitive and neurological alterations, cardiopulmonary affections(alone or combined), venous thromboembolism, gastrointestinal tract bleeding, urinary tract complications, perioperative anemia, electrolytic and metabolic disorders, and pressure scars are the most important medical complications after hip surgery in terms of frequency, increase of length of stay and perioperative mortality. Complications arising from hip fracture surgery are fairly common, and vary depending on whether the fracture is intracapsular or extracapsular. The main problems in intracapsular fractures are biological: vascularization of the femoral head, and lack of periosteum-a major contributor to fracture healing- in the femoral neck. In extracapsularfractures, by contrast, the problem is mechanical, and relates to load-bearing. Early surgical fixation, the role of anti-thromboembolic and anti-infective prophylaxis, good pain control at the perioperative, detection and management of delirium, correct urinary tract management, avoidance of malnutrition, vitamin D supplementation, osteoporosis treatment and advancement of early mobilization to improve functional recovery and falls prevention are basic recommendations for an optimal maintenance of hip fractured patients.

Purpose:To examine the effects of a school-based karate intervention on academic achievement,psychosocial functioning,and physical fitness in children aged 7-8 ***:Twenty schools in 5 different European countries(2 second-grade classrooms per school)participated in a cluster randomized controlled trial(Sport at School trial).Participants were assigned to either a control group,which continued with their habitual physical education lessons,or to an intervention group,which replaced these lessons with a 1-year karate intervention(Karate Mind and Movement program).A total of 721 children(344 girls and 377 boys,7.4±0.5 years old,mean±SD)completed the study,of which 333 and 388 were assigned to the control group and intervention group,*** included academic performance(average grade),psychosocial functioning(Strengths and Difficulties Questionnaire for parents),and different markers of physical fitness(cardiorespiratory fitness,balance,and flexibility).Results:The intervention provided small but significant benefits compared to the control group for academic achievement(d=0.16;p=0.003),conduct problems(d=-0.28;p=0.003),cardiorespiratory fitness(d=0.36;p0.05).Conclusion:A 1-year school-based karate intervention was effective in improving academic achievement,conduct problems,and physical fitness in primary school *** results support the inclusion of karate during physical education lessons.

Eucalyptus plantations are increasing in Brazil, frequently replacing pastures, but there is still scarce information about its capacity to maintain the fauna of neighbor forest remnants. In this study, we compared descriptors of the communities of leaf litter organisms （lizards, anurans, myriapods, arachnids, orthopterans, coleopterans, and ants） between a large remnant of primary Atlantic Forest and an adjacent eucalyptus monoculture （phase 1）. Then, we compared the same descriptors for leaf litter lizards and anurans, Euglossini bees, and frugivorous butterflies among the largest remnant, small remnants at intermediate regeneration stage, and eucalyptus monocultures that were not adjacent to the largest remnant （phase 2）. Monocultures were sampled immediately before logging. In phase 1, we detected significant differences in structure between the forest and the monoculture in six out of seven communities sampled. Ca. 81% of the species of the landscape were recorded in the forest, but only 54% of these were found also in the monoculture. In phase 2, the structure of two out of four forest communities was significantly different from the structure of small remnants and monocultures. On average, 76% of the species found in the whole landscape were sampled in the forest. Out of this subset, on average 74% of the species were also sampled in small remnants and 68% in monocultures. Findings of the present study point out a moderate capacity of eucalyptus monocultures to harbor species of the forest fauna even when fully grown but highlights the opportunity that they might offer for increasing connectivity in anthropogenic forest landscapes depending on their management.

Several pupil filtering techniques have been developed in the last few years to obtain transverse superresolution （a narrower point spread function core）. Such a core decrease entails two relevant limitations： a decrease of the peak intensity and an increase of the sidelobe intensity. Here, we calculate the Strehl ratio as a function of the core size for the most used binary phase filters. Furthermore, we show that this relation approaches the fundamental limit of the attainable Strehl ratio at the focal plane for any filter. Finally, we show the calculation of the peak-to-sidelobe ratio in order to check the system viability in every application.

随着市场经济的发展和物流专业化水平的提高,实体配送企业发展迅速。VRP是运输和物流配送中一个著名的组合优化问题。在某些情况下,客户需要同时从其所在地取货并将货物运送到其所在地。货物装载问题在配送中起着至关重要的作用。有效利用车辆空间和装载尽可能多的货物的能力。合理的装载计划可以提高汽车的装载率和空间利用率,降低分布式企业的物流成本,提高企业的竞争能力,给企业带来可观的经济效益,同时也为整个社会创造更多的价值。因此,车辆路径问题和货物装载问题已经得到了物流学者和企业的高度重视。传统的车辆路径问题在解决过程中只考虑简单的取货或送货。有回程车的车辆路径问题要求送货服务节点比取货服务节点早到,所以在其他情况下,车辆只考虑取货,不考虑送货,而其他车辆只考虑送货,不考虑取货,这样就不能完成服务,会增加运输成本。首先,本文分析了运输物流中出现的两个被认为是组合优化的问题,VRPSPD与所研究的货物配载装卸,都是属于NP-hard问题。本文的目标是找到最佳的装载配置,使货物体积和质量最小,以保持车内空间的利用率,并知道在每个需求点需要装载和卸载的货物总数,同时车辆返回时对货物体积和质量的具体需求。本文总结了有货物装载的VRPSPD的研究现状,并作为案例分析了物流配送优化问题的理论。本文选择了一个计算实例来分析货物装载的VRPSPD实际问题。本文选择了遗传算法来解决问题,对经典遗传算法进行了改进,得到了仿真实验的最优解。然后,对算法中的每一步都进行了具体而细致的设计,使算法紧凑、高效,适合解决组合优化问题,并建立了数学模型。同时,在设计过程中,还釆用MATLAB软件编写了程序来解决一个相关的实际问题,对设计的算法进行了实现。最后,得到的结果显示,通过基本的GA和改进的GA对车辆路径程序同时进行取货和送货的模拟实验的最佳目标函数迭代值是满意的。这些程序在很短的时间内获得了很好的、令人满意的结果。进一步验证了模型的有效性和合理性。
