EURASIP Journal on Advances in Signal Processing, 2023 Exploiting generalized spatial modulation in massive MIMO system, we develop an efficient uplink multiuser detection scheme. Different from the maximum likelihood detection algorithm, the spatial and temporal data in the proposed detection scheme are ...

Downscaling Daily Discharge to Sub‐Daily Scales for Alpine Glacierized Catchments
Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Hydrological dynamics in glacierized catchments of the Alps are shaped by temperature‐driven processes, including snow and ice melt as well as precipitation, leading to diel streamflow cycles that vary in intensity within‐ and among‐the seasons.

A Journey from Improper Gaussian Signaling to Asymmetric Signaling
, 2020 The deviation of continuous and discrete complex random variables from the traditional proper and symmetric assumption to a generalized improper and asymmetric characterization (accounting correlation between a random entity and its complex conjugate ...

The Future of High Frequency Circuit Design [PDF]
, 2009 The cut-off wavelengths of integrated silicon transistors have exceeded the die sizes of the chips being fabricated with them. Combined with the ability to integrate billions of transistors on the same die, this size-wavelength cross-over has produced

Benchmarking speech biomarkers of Alzheimer's against cognitive and neural measures
Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.Abstract INTRODUCTION Digital speech biomarkers (DSBs) support the detection and monitoring of Alzheimer's disease (AD) in Latinos. However, they have not been benchmarked against standard cognitive and neuroimaging measures, missing a critical validation milestone. METHODS Thirty‐three AD patients and 33 healthy controls completed verbal fluency tasks,

When is electromagnetic spectrum fungible? [PDF]
, 2012 Fungibility is a common assumption for market-based spectrum management. In this paper, we explore the dimensions of practical fungibility of frequency bands from the point of view of the spectrum buyer who intends to use it.

Why Size Does Not Matter: Sex Driven Home Range Differences in Brown Bears
Ecology and Evolution, Volume 16, Issue 4, April 2026.This is a novel anlaysis of unique dataset never find anywhere more than 60 collared free ranging brown bears movement data. ABSTRACT Sex, body size and environmental conditions are key determinants of home range size in large mammals, yet their relative importance within populations remains unclear for many wide‐ranging carnivores such as brown bears.
