Heavy metals impact environmental capacity of oasis soils in Qinghai-Tibet Plateau dry zone.

The Tibetan Plateau is known as the "third pole of the world," and plateau oases are a key component of plateau ecosystems. Under natural conditions, the ecosystems on the Tibetan Plateau contain relatively low levels of heavy metals. However, the overexploitation of resources by humans for production and living has affected the quality of soils in the Qinghai-Tibet region, whereby the environmental capacity is decreasing.

Control Power in Continuous Variable Controlled Quantum Teleportation.

HIV disease progression among heterosexually-infected individuals before the introduction of universal ART in China: A linear mixed-effects model.

In 2016, China introduced universal antiretroviral therapy (ART) for all HIV-infected individuals regardless of CD4 cell count. However, the natural history and rate of CD4 count decline among heterosexually-infected individuals remain uncharacterized. Analyzing national surveillance data can address this gap and shed light on the pathogenesis of HIV in this population.

Isolated theta waves originating from the midline thalamus trigger memory reactivation during NREM sleep in mice.

During non-rapid eye movement (NREM) sleep, neural ensembles in the entorhinal-hippocampal circuit responsible for encoding recent memories undergo reactivation to facilitate the process of memory consolidation. This reactivation is widely acknowledged as pivotal for the formation of stable memory and its impairment is closely associated with memory dysfunction. To date, the neural mechanisms driving the reactivation of neural ensembles during NREM sleep remain poorly understood.
