Beamforming Design for Joint Localization and Data Transmission in Distributed Antenna System

, 2014
A distributed antenna system is studied whose goal is to provide data communication and positioning functionalities to Mobile Stations (MSs). Each MS receives data from a number of Base Stations (BSs), and uses the received signal not only to extract the

Evolutionary Systematics of Two Co‐Occurring Paludomid Freshwater Gastropods in Thailand (Cerithioidea: Paludomidae)

Zoologica Scripta, Volume 55, Issue 2, Page 244-272, March 2026.
ABSTRACT Paludomidae is a diverse family of limnic gastropods in the Cerithioidea, with a distribution range including most of tropical sub‐Saharan Africa, the Nile Valley, Madagascar, the Seychelles, as well as South and Southeast Asia. Its systematics and taxonomy are currently in a state of confusion, with Thailand being inhabited by probably two ...

Kernel‐Based Estimation of Stratospheric Aerosol Radiative Effects From Volcanic and Wildfire Events

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract To facilitate the quantification of the stratospheric aerosol direct radiative effect (ARE), this study develops a suite of aerosol kernels based on Modern‐Era Retrospective Analysis for Research and Applications, Version 2 reanalysis data. The kernels comprise a five‐dimensional data set that includes latitude, longitude, time, wavelength ...

An Analytical Model of the Lifecycle of Tropical Anvil Cloud Radiative Effects

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Satellite observations and numerical simulations show that the small net Cloud Radiative Effect (CRE) of tropical anvil clouds results from a near‐cancellation between large but opposing longwave (LW) and shortwave (SW) components over the cloud's lifecycle.

Reduction of Global Sulfate Aerosol Concentration and Corresponding Radiative Effects From Recent Chinese SO2 ${\text{SO}}_{2}$ Emission Reduction

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Anthropogenic emissions over China have recently declined due to environmental actions. This work estimates the sensitivity of sulfate aerosol (SO4 ${\text{SO}}_{4}$) concentration to the amount of SO2 ${\text{SO}}_{2}$ emissions reduction over China from 2010 to 2020 using an Earth system model with two different aerosol representations.

The Atmosphere's Substantial Role in Interannual Variability of Earth's Energy Imbalance

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earth's Energy Imbalance (EEI) is a key metric to quantify climate change. While the ocean absorbs most excess heat, the atmosphere contributes only 1%–2% to the long‐term mean of EEI. However, our analysis of observational data demonstrates that variations in the atmosphere's energy content play a much larger role in interannual variations of
