Multi‐Source Adaptive‐Fusion Transfer Learning for Streamflow Forecasting in Data‐Scarce Catchments

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Streamflow gauging records remain sparse in many regions, limiting hydrological predictions. Transfer Learning (TL), which uses knowledge from data‐rich sources to improve predictions in data‐scarce targets, has emerged as a promising solution.

A Unified Vector Electromagnetic Framework for Ionospheric Scintillation and Polarization Effects in GNSS

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The ionosphere imposes coupled amplitude, phase, and polarization distortions on trans‐ionospheric Global Navigation Satellite System (GNSS) signals, reflecting the structure and dynamics of electron‐density irregularities. Classical weak‐scatter theory provides a mature framework for interpreting amplitude and phase scintillation, but these ...

bZIP Transcription Factor PobZIP8 Positively Mediates Heat Stress Tolerance and Negatively Regulates the Growth and Development of Pleurotus ostreatus

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
PobZIP8 from Pleurotus ostreatus enhances heat stress tolerance while negatively regulating fruiting body development, providing a key target for genetic improvement of edible fungi. ABSTRACT Pleurotus ostreatus is a globally cultivated edible and medicinal fungus, but its growth and yield are significantly affected by heat stress during cultivation ...

DEKOMPOSISI TUGAS-TUGAS SOFTWARE-DEFINED RADIO (SDR)

JURNAL TEKNOLOGI TECHNOSCIENTIA, 2019
This paper addresses decomposition of the tasks of Software-Defined Radio (SDR) computation by taking Gaussian Minimum Shift Keying (GMSK) as a case study. The aim of this research was to produce a task graph of the SDR that was needed in scheduling of distributed computing with task parallelism using genetics algorithm.

Downward Positive Leader Propagation Modes and Their Effects in Positive Cloud‐to‐Ground Lightning Characteristics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The return stroke in a cloud‐to‐ground (CG) flash is initiated when the downward leader either reaches the ground or connects with an upward leader from a grounded structure. Unlike negative downward leaders, which typically propagate in a highly branched manner, downward positive leaders (DPLs) can propagate either in a branched or unbranched

Case Studies of Attacks over Adaptive Modulation Based Tactical Software Defined Radios

Journal of Computer Networks and Communications, 2012
This paper presents case studies of attacks aimed at tactical software defined radios based on a classification with the most common sources of vulnerabilities, classes of attacks, and types of intrusions that military radio sets may suffer. Besides that,

Marmote SDR: Experimental Platform for Low-Power Wireless Protocol Stack Research

Journal of Sensor and Actuator Networks, 2013
Over the past decade, wireless sensor network research primarily relied on highly-integrated commercial off-the-shelf radio chips. The rigid silicon implementation of the radio stack restricted access to the lower layers; thus, research focused mainly on

Direct Laser Interference Patterning of Nickel Foils for Enhanced Bubble Nucleation in Oxygen‐Oversaturated Environment

Advanced Energy and Sustainability Research, Volume 7, Issue 5, May 2026.
This study investigates the use of direct laser interference patterning (DLIP) to enhance oxygen bubble nucleation on nickel surfaces by creating periodic microstructures with controlled spatial periods and depths. The results demonstrate that smaller spatial periods (Λ) and deeper features significantly improve bubble density and detachment dynamics ...
