Climate shocks and responses: Perspectives and experiences of ethnic minority farmers in rural mountainous regions of Central Vietnam.

Ethnic minority farmers (EMFs) in upland areas of Central Vietnam are particularly vulnerable to the impacts of climate shocks and extreme events. It is thus urgent to examine their perceptions of the potential risks, their coping strategies, and the factors influencing their adaptation decisions in agriculture production. By exploring adaptation measures of the Xo Dang and Co Tu EMFs in Quang Nam province, Central Vietnam, the study results reveal that the EMFs are increasingly conscious of local climate shocks in the recent decade; as a result, they have applied multiple specific strategies in agriculture production to mitigate risks.

Anonazepine, a new alkaloid from the leaves of (Annonaceae).

From the CHCl-soluble extract of L. (Annonaceae) leaves, one new 3-benzazepine-type alkaloid, anonazepine (), and four known aporphine-type alkaloids, (+)-laurotetanine (), (+)-norglaucine (), (-)-xylopine (), and lanuginosine (), were isolated. Except for (-)-xylopine (), these remaining known alkaloids were first reported in .

NIR self-powered photodetection and gate tunable rectification behavior in 2D GeSe/MoSe heterojunction diode.

Two-dimensional (2D) heterostructure with atomically sharp interface holds promise for future electronics and optoelectronics because of their multi-functionalities. Here we demonstrate gate-tunable rectifying behavior and self-powered photovoltaic characteristics of novel p-GeSe/n-MoSe van der waal heterojunction (vdW HJ). A substantial increase in rectification behavior was observed when the devices were subjected to gate bias.

The phenotypic characteristics and relational database for Vietnamese native pig populations.

Although there are a number of Vietnamese native pig (VnP) populations, some are on the verge of extinction, and therefore adequate management and conservation are necessary. In this study, we conducted a field survey of VnP populations and analyzed interrelationships among their characteristics. We also established a relational database for management of field data on these populations.
