ABSTRACT Anthropological engagement with moralities and ethics assumes that people evaluate themselves and others according to their notions of good and bad; yet little is known about how people evaluate the quality of their deliberations. Such evaluations of the seriousness of ethical deliberations prevail in Japan's genetic counseling for pregnant ...

Identifying treponemal disease in early East Asia
Syphilis in China before Vasco da Gama? Abstract Objectives Historic records suggest that a virulent form of treponematosis, sexually transmitted syphilis was introduced to Asia from Europe by the da Gama crew, who landed in India in 1498. Our objective is to assess the gross pathology of human skeletal remains from the Tang dynasty of China to test ...

ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the

ABSTRACT Prelithiation is effective for compensating active lithium‐ion (Li+) loss in silicon (Si)‐based battery electrode materials. However, owing to the dynamic growth of the solid electrolyte interface (SEI), capacity fading remains the biggest challenge for the industrialization of Si electrodes.

促卵泡成熟激素结合精液细胞学检测探讨无精子症睾丸生精功能的临床研究
目的外周血清激素FSH结合精液细胞学检查对无精子症睾丸生精功能的评价,以指导临床对无精子症患者的诊断。方法选择43例无精子症患者,测定外周血清激素FSH水平以及精液细胞学,按FSH值不同分成A、B、C3组,观察各组精液细胞检出率,另外将精液细胞按形态及染色特点分为精原细胞、精母细胞和精子细胞3组,比较组间FSH水平差异有无显著性意义。结果A组精液细胞检出率为0,B组精液细胞检出率为38%,C组精液细胞检出率为60%。三组间精原细胞组与精母细胞组、精子细胞组的FSH的差别有统计学意义(P0.05 ...

ABSTRACT The realization of bifunctional perovskite devices integrating photovoltaic (PV) and light‐emitting diode (LED) capabilities requires precisely controlled grain architectures to facilitate dual carrier transport pathways. In this work, sulfaguanidine (SG) molecules were introduced into the perovskite solution to reconstruct the crystallization
