The Open-Source Digital Elevation Model (DEM) is fundamental data of the geoscientific community. However, variation its accuracy with land cover type and topography has not been thoroughly studied. This study evaluates five globally covered open-accessed DEM products (TanDEM-X90 m, SRTEM, NASADEM, ASTER GDEM, AW3D30) in mountain area using ICESat/GLAS as GCPs. robust evaluation indicators were...

Although mechanisms that contribute to microtubule (MT) aster positioning have been extensively studied, still little is known on how asters move inside cells to faithfully target a cellular location. Here, we study sperm aster centration in sea urchin eggs, as a stereotypical large-scale aster movement with extreme constraints on centering speed and precision. By tracking three-dimensional ast...

Freshwater resources present in the Upper Indus Basin (UIB) supply water to Pakistan’s irrigation. Half of annual discharge UIB is contributed from glacier and snow-fed basins Hindu Kush, Karakoram, Himalaya (HKH) region, it currently under threat climate change. Therefore, very necessary study monitor spatiotemporal changes snow cover area (SCA) its response variables efficiently manage reserv...

Publicly available Digital Elevation Models (DEM) derived from various space-based platforms (Satellite/Space Shuttle Endeavour) have had a tremendous impact on the quantification of landscape characteristics, and related processes products. The accuracy elevation data six major public domain satellite-derived (a 30 m grid size—ASTER GDEM version 3 (Ast30), SRTM (Srt30), CartoDEM V3R1 (Crt30)—a...

Geological mapping undoubtedly plays an important role in several studies and remote sensing data are of great significance geological mapping, particularly poorly mapped areas situated inaccessible regions. In the present study, Principal Component Analysis (PCA), Band Rationing (BR) Minimum Noise Fraction (MNF) algorithms applied to map lithological units extract lineaments Amezri-Amassine ar...

Anthropogenic stressors have altered the hydromorphological characteristics of rivers worldwide. Environmental guiding principles are essential for planning sustainable river restoration measures. The alpine Biya, located in Russian Altai mountains, originates from Lake Teletskoye and joins Katun near Biysk, forming Ob. Biya represents a reference system anthropogenically ‘least-disturbed’ cond...

This paper presents a new phase-based theory of verb-second and indeed model the left periphery. I argue that V-to-C movement verb to phase head Fin0 has profound repercussions on clausal syntax which explains well-known differences between Modern Germanic V2 languages Romance non-V2 with respect topicalisation. also explore how proposed analysis can account for linear restriction prefield in a...
