Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone
Ecography, EarlyView.This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

Simulating past and future refugia for temperate trees in northern Italy
Ecography, EarlyView.During the Quaternary, trees responded to the climatic changes of glacial–interglacial cycles with large‐scale range shifts. Over cold glacials, temperate tree species contracted their ranges and survived in areas known as refugia. Several studies point to the Euganean Hills (Colli Euganei), in Veneto, northern Italy, as one of the northernmost ...

Non-uniform wordlength delay lines for FIR filters [PDF]
, 2009 When FIR filters are designed floating point arithmetic is generally used. However when implemented on hardware such as ASICs, fixed point arithmetic must be used to minimise cost and power requirements.

Considerations When Sampling Spruce Budworm Egg Masses on Balsam Fir and White Spruce in the Lake States: Low Population Levels [PDF]
, 2017 One cluster each of balsam fir, Abies balsamea, and white spruce, Picea glauca, trees was chosen from each of five stands of spruce-fir in Michigan\u27s Upper Peninsula.

Epilepsia, EarlyView.Cong Fu et al. demonstrate that glymphatic system dysfunction is linked to enhanced inhibitory cortical activity using diffusion MRI and EEG. These findings highlight a mechanistic link between perivascular fluid dynamics and neuronal activity, suggesting a role for glymphatic function in maintaining cortical stability in epilepsy.

Molecular Gas in Lensed z >2 Quasar Host Galaxies and the Star Formation Law for Galaxies with Luminous Active Galactic Nuclei [PDF]
, 2011 We report the detection of luminous CO(J = 2→1), CO(J = 3→2), and CO(J = 4→3) emission in the strongly lensed high-redshift quasars B1938+666 (z = 2.059), HE 0230-2130 (z = 2.166), HE 1104-1805 (z = 2.322), and B1359+154 (z = 3.240), using the Combined ...

Journal of Applied Toxicology, EarlyView.ABSTRACT In this study, ten novel compounds (IPH1–IPH10) were designed by integrating three pharmacophores (isatin, piperazine, and hydrazone) commonly found in the molecular structures of anticancer agents. The target molecules were obtained by the reaction of in‐house prepared 4‐(4‐(pyridin/pyrimidin‐2‐yl)piperazin‐1‐yl)benzohydrazide with various ...
