Spruce trees have stronger drought sensitivity at low- than high-elevation sites across China’s aridity zones

Global Ecology and Conservation
The ecological relationships between tree growth and climate factors are important for the adaptation, growth prediction, and forest management of tree species against a background of global warming.

The structure of forest stands in the Tatra National Park: The results of 2016–2017 inventory

Leśne Prace Badawcze, 2019
The composition and structure of forest stands in the Tatra National Park were examined using data gathered in 2016 and 2017 from 617 circular sample plots (0.05 ha each). The diameter at breast height of all living trees, standing dead trees, snags, and

Monocyte LOXHD1 and RHOB Expression Predictive of Progressive Systemic Sclerosis–Associated Interstitial Lung Disease

Arthritis Care &Research, EarlyView.
Objective A leading cause of death among patients with scleroderma (SSc), interstitial lung disease (ILD) remains challenging to prognosticate. The discovery of biomarkers that accurately determine which patients would benefit from close monitoring and aggressive therapy would be an essential clinical tool.

Projected rising temperatures and vapour pressure deficit threaten Arabica coffee production Tanzania's burgeoning coffee region: Empirical insight from Mbinga district, Tanzania

Environmental Challenges
Tanzania is emerging as a key coffee producer, but climate change poses a serious threat to coffee production in the country. While extensive literature addresses climatic variables’ trends and variability in coffee-growing regions globally, elevation, a

Amorphous zone evolution in Si during elevated temperature ion bombardment

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2001
Abstract Evolution of amorphous zones (a-zones) in Si during elevated temperature ion/electron bombardment is considered. Consideration is based on a point defect diffusion model for the ion-beam-induced amorphous–crystalline (a/c) phase transformation in Si. Direct thermal annealing and an additional interfacial driving force for crystallization are

Response of hydrological processes to input data in high alpine catchment : an assessment of the Yarkant River basin in China [PDF]

, 2016
Most studies of input data used in hydrological models have focused on flow; however, point discharge data negligibly reflect deviations in spatial input data.

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller

International Journal of Adaptive Control and Signal Processing, EarlyView.
Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...

Numerical modelling in support of a conceptual model for groundwater flow and geochemical evolution in the southern Outaouais Region, Quebec, Canada [PDF]

, 2017
A two-dimensional vertical-section numerical model for groundwater flow and transport using age, tritium and chloride was used to help validate a conceptual model of geochemical evolution within a representative regional-scale hydrogeological system in ...

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

Advanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...
