Phosphorus addition diminishes the negative effect of nitrogen addition on methane sink in subtropical forest soils.

Increased global nitrogen (N) and phosphorus (P) inputs caused by human activities can significantly impact methane (CH) uptake in terrestrial ecosystems. Forest soils, as the largest CH sink among terrestrial ecosystems, play a crucial role in mitigating global warming. However, the effects of long-term N and P additions on CH sink and the associated microbial mechanisms in subtropical forest soils remain unclear.

Transformation processes of total suspended solids and dissolved organic matter in rivers: Influences of different land use sources and degradation processes.

Human activities significantly alter the distribution of organic matter (OM) in rivers, thereby affecting the availability of DOM. However, the impact of total suspended solids (TSS) on DOM under anthropogenic influence remains insufficiently elucidated.

A review of effects of electromagnetic fields on ageing and ageing dependent bioeffects of electromagnetic fields.

In the Greater Khingan Mountains of Northeast China, where forest and peatland ecosystems are interspersed extensively, prescribed burning is conducted annually on peatlands to prevent major forest fires. To investigate the effect of prescribed burning on carbon and nutrient cycling processes in peatlands, we conducted a three-year experiment in the Greater Khingan Mountains.

Soil moisture drought and diverse impacts on vegetation across the Tibetan Plateau in recent three decades.

Molecularly manipulating pyrazinoquinoxaline derivatives to construct NIR-II AIEgens for multimodal phototheranostics of breast cancer bone metastases.

Multimodal phototheranostics on the basis of single molecular species shows inexhaustible and vigorous vitality, particularly those emit fluorescence in the second near-infrared window (NIR-II), the construction of such exceptional molecules nonetheless retains formidably challenging. In view of the undiversified molecular skeletons and insufficient phototheranostic outputs of previously reported NIR-II fluorophores, herein, electron acceptor engineering based on heteroatom-inserted rigid-planar pyrazinoquinoxaline was manipulated to fabricate aggregation-induced emission (AIE)-featured NIR-II counterparts with donor-acceptor-donor (D-A-D) architecture. Systematical investigations substantiated that one of those synthesized AIE molecules, namely 4TPQ, incorporating a fused thiophene acceptor, synchronously exhibited high molar absorptivity (ε), NIR-II emission, typical AIE tendency, significant reactive oxygen species (ROS) generation, and high photothermal conversion efficiency.

A position coding model that accounts for the effects of event boundaries on temporal order memory.

Episodic memories, particularly temporal order memory, are influenced by event boundaries. Although numerous theoretical and computational models have been developed to explain this phenomenon, creating a model that can explain a wide range of behavioral data and is supported by neural evidence remains a significant challenge. This study presented a new model, grounded in ample evidence of position coding, to account for the impact of event boundaries on temporal order memory.
