A simple set of indices describing the Tropical Rain Belt over central and southern Africa

Atmospheric Science Letters, 2019
Understanding the variability of the Tropical Rain Belt (TRB) in Africa is a challenging task due to complex interactions among global, regional and local drivers of rainfall.

Inter-annual climate variability and zooplankton: applying teleconnection indices to two deep subalpine lakes (Lake Maggiore and Lake Garda) [PDF]

, 2012
In recent years, increasing interest has been shown on impact of inter-annual climate variability to zooplankton. Especially in North American great lakes, and in the large subalpine lakes north of the Alps, research has focused on impact of NAO-derived ...

Agnuside Stabilizes the Complex I Assembly Factor NDUFAF6 to Reinforce Mitochondrial Efficiency and Thermogenic Responsiveness

Advanced Science, EarlyView.
ABSTRACT Brown and beige adipocytes dissipate energy as heat, yet effective strategies to enhance their mitochondrial efficiency remain limited. Here, we identify Agnuside (AGN) as a selective stabilizer of the complex I assembly factor NDUFAF6. AGN directly binds cytosolic NDUFAF6, suppresses its ubiquitination, prolongs its half‐life, and facilitates

Dissecting the Ecological Structure of Health and Disease in the Global Gut Microbiome

Advanced Science, EarlyView.
We introduce Wiredancer, a framework that identifies three continuous ecological factors of the gut microbiota. These factors exhibit distinct patterns across health and disease, jointly capturing disrupted ecological stability and offering a new perspective for precision diagnostics and therapeutic strategies.

Canagliflozin Alleviates Diabetic Glomerular Endothelial Injury via Melibiose in a Microbiota‐Dependent Manner

Advanced Science, EarlyView.
Canagliflozin treatment reshapes the gut microbiota in DKD and elevates levels of melibiose, a metabolite derived from Roseburia intestinalis. Melibiose directly binds to and enhances the enzymatic activity of glyoxalase 1, leading to decreased methylglyoxal accumulation.

Changes in precipitation extremes projected by a 20-km mesh global atmospheric model

Weather and Climate Extremes, 2016
High-resolution modeling is necessary to project weather and climate extremes and their future changes under global warming. A global high-resolution atmospheric general circulation model with grid size about 20 km is able to reproduce climate fields as ...

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

Advanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Modelling surface climate over complex terrain for landscape ecology [PDF]

, 2000
Climate exerts a fundamental control on ecosystem function, species diversity and distribution. Topographic variability may influence surface climate, through processes operating at a landscape- scale.

Climate-informed clustering based nonstationary regional extreme flood events spatio-temporal evolution using hierarchical Bayesian modeling

Journal of Hydrology: Regional Studies
Study region: Xiangjiang River basin, is at the middle and lower Yangtze River. Study focus: Increasing evidence shows that large-scale climate indices are being linked to the spatio-temporal evolution of extreme flood events in many regions.

Hamiltonian distributed chaos in large-scale climate dynamics

, 2018
It is shown that the large-scale climate dynamics, represented by the daily indices of the North Atlantic (NAO), Pacific/North American (PNA), Arctic (AO) and Antarctic (AAO) oscillations, Asian-Australian Monsoons (ISM, WNPM and AUSM) and El Nino/La ...
