Veterinary drugs are substances(including pharmaceutical feed additives)used to prevent,treat,and diagnose diseases or regulate the physiological functions of animals.Veterinary drug poisoning in humans is relatively rare both in China and the rest of the world.Here,we report a case of death from veterinary drug poisoning from avermectin-closantel.Avermectin-closantel is a broad-spectrum antiparasitic drug,which has high efficacy against a variety of trematodes and nematodes.

This paper deals with the robust stability of time-delay system with time-varying uncertainties via homogeneous polynomial Lyapunov-Krasovskii functions(HPLKF). We give a sufficient condition to demonstrate that the system is asymptotically stable.A new class of Lyapunov-Krasovskii function is introduced, whose main feature is that the conservativeness due to uncertainties is reduced. Numerical examples illustrate the effectiveness of our method.

This paper proposes a longitudinal protection scheme utilizing empirical wavelet transform(EWT)for a through-type cophase traction direct power supply system,where both sides of a traction network line exhibit a distinctive boundary structure.This approach capitalizes on the boundary’s capacity to attenuate the high-frequency component of fault signals,resulting in a variation in the high-frequency transient energy ratio when faults occur inside or outside the line.During internal line faults,the high-frequency transient energy at the checkpoints located at both ends surpasses that of its neighboring lines.Conversely,for faults external to the line,the energy is lower compared to adjacent lines.EWT is employed to decompose the collected fault current signals,allowing access to the high-frequency transient energy.The longitudinal protection for the traction network line is established based on disparities between both ends of the traction network line and the high-frequency transient energy on either side of the boundary.Moreover,simulation verification through experimental results demonstrates the effectiveness of the proposed protection scheme across various initial fault angles,distances to faults,and fault transition resistances.

生活垃圾逆向物流是村镇生活垃圾治理的关键纽带。揭示生活垃圾逆向物流模式的空间分异机制、构筑经济高效的生活垃圾逆向物流体系,对农牧交错带生态安全格局稳定、村镇人居环境品质提升具有重要意义。以青海省海东市为实证对象,构建1499个村镇居民点的多源异构数据集,多尺度刻画垃圾治理效能地域非均衡性,应用多项逻辑斯蒂回归模型定量解析垃圾逆向物流模式空间分异的影响因素,并基于改进潜能模型的设施空间可达性评价,提出逆向物流模式空间优化方案。结果显示:海东市生活垃圾呈“局部集聚、总体分散”分布,垃圾治理效能滞后于原住居民生活需求,由湟水谷地中心向周边农区村镇、牧民定居点呈水平递减;农牧交错带地理环境高寒性与村镇聚落分散性,是阻碍集中式物流模式配置的根本原因;常住人口规模小、社会经济发展状态较差的村镇居民点是集中式物流模式配置的薄弱区域;充足的基层管理人员数量和年轻化干部群体,有利于落实村分散物流模式管理要求;海东市村镇居民点垃圾处理设施空间可达性偏低,应以城镇集中式、乡镇传导式、农牧分散式3类路径为遵循,采用集中式与分散式物流并举的调适策略进行逆向物流模式全局优化。建议以物流成本最小化、垃圾治理零胁迫为导向,兼顾各级物流节点功能特性分类施策,发挥县域垃圾逆向物流软硬件设施统筹职能,激活乡镇垃圾协同治理效能,强化村庄源头分类与就地消纳功能,营造减量化、资源化、无害化的生活垃圾逆向物流体系。

Recent studies have shown that the construction of nanophononic metamaterials can reduce thermal conductivity without affecting electrical properties,making them promising in many fields of application,such as energy conversion and thermal management.However,although extensive studies have been carried out on thermal conductivity reduction in nanophononic metamaterials,the local heat flux characteristic is still unclear.In this work,we construct a heat flux regulator which includes a silicon nanofilm with silicon pillars.The regulator has remarkable heat flux regulation ability,and various impacts on the regulation ability are explored.Surprisingly,even in the region without nanopillars,the local heat current is still lower than that in pristine silicon nanofilms,reduced by the neighboring nanopillars through the thermal proximity effect.We combine the analysis of the phonon participation ratio with the intensity of localized phonon modes to provide a clear explanation.Our findings not only provide insights into the mechanisms of heat flux regulation by nanophononic metamaterials,but also will open up new research directions to control local heat flux for a broad range of applications,including heat management,thermoelectric energy conversion,thermal cloak,and thermal concentrator.

BACKGROUND Brain metastases(BM)are very rare in gastric adenocarcinoma(GaC),and patients with BMs have a higher mortality rate due to stronger tumor aggressiveness.However,its pathogenesis remains unclear.Genetic testing revealed cellular-mesenchymal epithelial transition factor receptor(MET)amplification.Therefore,treatment with savolitinib,a small molecule inhibitor of c-Met,was selected.CASE SUMMARY A 66-year-old woman was diagnosed with advanced GaC 6 months prior to presentation due to back pain.Cerebellar and meningeal metastases were observed during candonilimab combined with oxaliplatin and capecitabine therapy.The patient experienced frequent generalized seizures and persistent drowsiness in the emergency department.Genetic testing of cerebrospinal fluid and peripheral blood revealed increased MET amplification.After discussing treatment options with the patient,savolitinib tablets were administered.After a month of treatment,the intracranial lesions shrank considerably.CONCLUSION BM is very rare in advanced GaC,especially in meningeal cancer,that is characterized by rapid disease deterioration.There are very few effective treatment options available;however,technological breakthroughs in genomics have provided a basis for personalized treatment.Furthermore,MET amplification may be a key driver of BM in gastric cancer;however,this conclusion requires further investigation.

BACKGROUND The advanced first-line regimen for advanced gastric cancer is based on a combination of fluoropyrimidine and platinum and/or paclitaxel(PTX),forming a two-or three-drug regimen.Compared to conventional PTX,nanoparticle albumin-bound PTX(Nab-PTX)has better therapeutic effects and fewer adverse effects reported in studies.Nab-PTX is a great option for patients presenting with advanced gastric cancer.Herein,we highlight an adverse event(hemorrhagic cystitis)of Nab-PTX in advanced gastric cancer.CASE SUMMARY A 55-year-old male was diagnosed with lymph node metastasis after a laparo-scopic-assisted radical gastrectomy for gastric cancer that was treated by Nab-PTX and S-1(AS).On the 15th day after treatment with AS,he was diagnosed with hemorrhagic cystitis.CONCLUSION Physicians should be aware that hemorrhagic cystitis is a potential adverse event associated with Nab-PTX treatment.

The pollutant control performance of exhaust hoods plays a crucial role in the indoor air quality and energy consumption of ventilation systems in industrial buildings.To better understand the impact of local ventilation on the industrial indoor environment,this paper presents a literature review of exhaust hood performance and its improvement technologies.To create an index for evaluating the performance of exhaust hoods,the capture velocity,capture efficiency,flow ratio of pollutant emissions and exhaust airflow and energy consumption are first introduced.A number of factors affecting exhaust hood performance are assessed such as hood type,hood opening size,exhaust rate,installation distance,pollution source emission and environmental disturbance.Compared to structural improvement methods,the use of active airflow is a more effective way to improve the exhaust hood performance.The most commonly used methods for determining the exhaust rate are the controlled speed method and the flow ratio method.The use of an exhaust hood with an appropriate exhaust rate and jet parameters(for an active air-assisted hood)can effectively improve the pollutant control performance and reduce the energy consumption that would be wasted on the redundant exhaust rate.With more information focused on exhaust hood performance,this work suggests more effective strategies for improving indoor air quality and reducing energy consumption in industrial buildings.
