The Greenland Ice Sheet is a key component of the Earth’s climate system and assessing its mass balance is crucial for predicting sea-level rise. Solid ice discharge is a critical parameter that can be determined by ca...

Questions: (1) Can above-ground net primary production (ANPP) of Patagonian meadows be estimated from remote sensing? (2) How does ANPP of Patagonian meadows change in space and time? Location: Northwestern Patagonia, me...

Large-scale topographic information is often difficult to obtain accurately. Technological advances in the field of surveying provide sophisticated instruments with varying degrees of accuracy. One of the widely used ins...

Contamination with anthropogenic debris, such as plastic and paint particles, has been widely investigated in the global marine environment. However, there is a lack of information regarding their presence in marine prot...

This paper reports on the April-May 1983 Projeto Flora expedition to Serra do cachimbo in northcentral Brazil, a phytogeographically poorly known area near the transition between the Amazon forest and the central Brazili...

Background: A brain tumor is a tumor that is most known for its dangerous progressivity. Brain tumor is classified into primary and metastatic types. One of the management for primary brain tumors is radiotherapy. This s...

Accurately predicting the potential distribution of Setaria palmifolia in China is crucial for assessing its climatic adaptability as a forage resource and for developing sustainable utilization strategies. This study sy...

Glaciers in the northern Patagonian Andes (35-46°gS) have shown a dramatic decline in area in the last decades. However, little is known about glacier mass balance changes in this region. This study presents a geodetic ...

Abstract While the interbreeding of Homo neanderthalensis (hereafter Neanderthal) and Anatomically modern human (AMH) has been proven, owing to the shortage of fossils and absence of appropriate DNA, the timing and geogr...

In the ecologically fragile karst region of Hechi City, Guangxi, unique landforms and human activities have increased demand for multiple ecosystem services (ES), degrading ecological functions, weakening ecological netw...

Abstract The electrical structure of oceanic lithosphere and underlying asthenosphere provides crucial constraints on upper mantle dynamics, complementing seismic observations to distinguish between competing mechanisms ...

Abstract High discharge events propagate down rivers as flow waves. River wave movements are described theoretically by routing equations or tracked using in‐situ gauge measurements of stage over time at a given locati...

Abstract We present a first examination of observations from the surface water and ocean topography (SWOT) mission over the polar oceans. In SWOT, bright, quasi‐specular leads are associated with lower heights relative...

Shape Manifestation of Respiration in the Axial System The aim of the study was to evaluate the effect of respiration on the shape changes of the axial system. Our approach focuses more on the analysis of respiratory fu...

Abstract In this study, the spatiotemporal characteristics and influencing mechanisms of eddy–eddy interactions in the Agulhas leakage region (ALR) from 1993 to 2023 are investigated. We use satellite observations and ...

Transparent conductive oxides (TCOs) are used in solar cells not only to extract photogenerated carriers but also to allow sunlight to reach the photoactive material. Therefore, controlling the electrical and optical pro...

Rapid urbanization and increasing energy demand have intensified environmental pressures, particularly in the transportation sector, which remains one of the largest contributors to greenhouse gas emissions. Although ele...

Antimicrobial drug resistance is a serious challenge in clinical settings worldwide, with biofilm formation having been associated with this problem. In the present study, the synergism of oligostyrylbenzene (OSB) compou...

At the southern margin of the Andean Puna plateau and within the northernmost Argentine broken foreland, at 28° SL, one of the largest and a highest intermontane basin of the Sierras Pampeanas develop: the Pipanaco Basi...
