Examining the effect of an aerobic exercise program on stress and triglycerides level in sedentary students

open access: yesInternational Journal of Occupational Safety and Health, 2017
Background: Stress is a risk factor for developing hypertension and cardiovascular diseases. The increased risk of cardiovascular diseases from chronic stress has been linked to increased plaque build-up as a result of elevated cholesterol, hardening of ...

An evaluation of EU-DEM in comparison with ASTER GDEM, SRTM and contour-based DEMs over the Eastern Mecsek Mountains

open access: yesHungarian Geographical Bulletin, 2014
The availability of global coverage digital surface models (like ASTER GDEM or SRTM) and the variation of fused models based on these (like EU-DEM) still has a great impact on scientific researches, as they provides a fairly good base dataset with a low ...

Independent Component Analysis (ICA) as a Superior Atmospheric Correction Method for InSAR Time Series

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Satellites such as the European Space Agency's Sentinel‐1 constellation allow for the creation of unprecedented volumes of Interferometric Synthetic Aperture RaDAR data that contains both deformation and atmospheric signals. Correction methods have been developed to reduce these atmospheric signals, but they do not generally perform well on ...

Deforestation Triggers State‐Dependent Cloud Regimes in the Amazon

open access: yesEarth's Future, Volume 14, Issue 8, August 2026.
Abstract The Amazon's arc of deforestation is a hotspot of rapid land‐cover change. Using 20 years of MODIS imagery combined with cloud property retrievals, CERES radiative fluxes, and ERA5 data, we show that deforestation consistently enhances low‐level cloudiness over non‐forest relative to nearby forest during the Amazon dry season.

Grain Expansion in China's Drylands Secures Food but Intensifies Environmental Trade‐Offs

open access: yesEarth's Future, Volume 14, Issue 8, August 2026.
Abstract Drylands are increasingly crucial for global food supply, and grain cultivation there continues to expand. Newly cultivated croplands in these regions are often assumed to be biophysically marginal and low yielding. However, the food‐security benefits, environmental costs, and associated trade‐offs of this expansion remain insufficiently ...

SRTM resample with short distance‐low nugget kriging

open access: yesInternational Journal of Geographical Information Science, 2008
The shuttle radar topography mission (SRTM), was flow on the space shuttle Endeavour in February 2000, with the objective of acquiring a digital elevation model of all land between 60° north latitude and 56° south latitude, using interferometric synthetic aperture radar (InSAR) techniques. The SRTM data are distributed at horizontal resolution of 1 arc-

Diagnosing Cryospheric Runoff Dynamics: A Distributed Differentiable Hydrological Model With Global Transfer Learning

open access: yesWater Resources Research, Volume 62, Issue 8, August 2026.
Abstract Accurate hydrological prediction in alpine regions remains challenging due to complex cryospheric processes and limited observational records. Traditional hydrological models are often subject to structural uncertainty, whereas purely data‐driven deep learning (DL) models may lack physical interpretability under non‐stationary climate ...

Understanding mammal avoidance of human settlements

open access: yesJournal of Animal Ecology, Volume 95, Issue 8, Page 1504-1517, August 2026.
Terrestrial mammals often avoid human settlements, but is this a result of human activity around buildings or the built infrastructure per se? Using data on animal movement before and during the COVID‐19 lockdowns, this paper disentangles these effects, showing how changes in human mobility affect animals' avoidance of buildings. Abstract Anthropogenic

Digital elevation models and their use for assessing soil erosion rates on arable lands

open access: yesУчёные записки Казанского университета: Серия Естественные науки, 2018
The paper presents the results of assessing the accuracy of global digital elevation models (GDEMs), SRTM and ASTER GDEMs, based on a small catchment located on the eastern slope of the Central Russian Upland in the upper reaches of the Veduga River ...

The impact of social media marketing activities on brand loyalty and awareness: the mediating role of customer satisfaction in Yemen’s telecom industry

open access: yesCogent Business & Management
In the competitive telecommunications sector in Yemen, companies face challenges in fostering brand loyalty and awareness through digital marketing efforts. Social media marketing activities (SMMAs) have emerged as a key strategy, yet their effectiveness
