ABSTRACT Vanadium oxides are deemed competitive cathode candidates for aqueous zinc‐ion batteries (AZIBs), benefited from their high theoretical capacity and multiple crystalline structures. However, the sluggish reaction kinetics, poor reversibility, and high solubility have hindered the practical application.

Deep quantile regression for growth and maturation reaction norms
Abstract Understanding species' growth and maturation responses to anthropogenic and environmental pressures is crucial for tracking demographic shifts, phenotypic change and ensuring population sustainability. Traditional regression methods often focus on modelling the conditional mean of life‐history traits, potentially overlooking heterogeneity in ...

Analysis about ultrasonic misdiagnosis of lower extremity venous thrombosis [PDF]
目的通过对下肢静脉血栓超声患者的超声资料进行回顾性分析,总结分析误诊漏诊的原因方法对70例临床怀疑为下肢静脉血栓的病人进行常规静脉彩超检查,对确诊为下肢静脉血栓的患者再行CT静脉造影检查,而后对两者诊断结果进行对照分析。结果 70例临床疑似为下肢静脉血栓病人中,确诊率为57.1%(40/70),超声误诊率32%(8/25)。结论超声检查无创伤、重复性高,可准确诊断下肢静脉血栓形成。Objective The data of patients with lower extremity venous ...
