Integrated Evaluation of Contaminant Profiles, Detection Techniques, and Management Strategies for Tannery Sludge

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.
ABSTRACT This review article critically examines the environmental and health hazards of tannery sludge (TS), a complex by‐product of the leather tanning industry. TS is characterized by a diverse array of contaminants, including heavy metals like chromium, organic pollutants such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds ...

Precoding Aided Generalized Spatial Modulation With an Iterative Greedy Algorithm

IEEE Access, 2018
This paper divides antennas at the transmitter into several transmit antenna groups (TAGs) and extends the generalized spatial modulation (GSM) idea to a new precoding-aided multiple-input multiple-output system, which is referred to as precoding-aided ...

Anthropogenic Infrastructures Shape Brown Bear Movements in Human‐Modified Landscapes

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Human activities are major drivers of changes in animal behaviour, resulting in diverse spatial and temporal activity patterns across species. In this study, we analysed telemetry data from brown bears in Finland, Slovakia and Romania, to compare how human infrastructure influences their movement behaviour.

Performance evaluation of generalized optical spatial modulation with dimming support

, 2018
In this paper, we propose a modified generalized spatial modulation (MGSM) scheme with dimming support for indoor optical wireless communication (OWC) systems. The spatial indices of the active LEDs and their transmitted optical power levels are utilized

Late summer plateau pika spatial habitat use revealed by high‐resolution wildlife tracking and unmanned aerial vehicle data on the Qinghai–Tibet Plateau

Grassland Research, Volume 5, Issue 1, Page 24-34, March 2026.
Tiny “ecosystem engineers,” plateau pikas range across 1600 m², about two basketball courts, mixing soil and nutrients that sustain Tibet's fragile grasslands. Custom‐made trackers and drone imagery show dawn‐to‐dusk surface foraging and nested‐scale patch choices, offering fresh guidance for wildlife‐friendly grazing management.

Characterizing Ion‐Scale Fluctuations Around Dipolarization Fronts in Earth's Magnetotail

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract In the Earth's magnetotail bursty bulk flows are often associated with dipolarizing magnetic flux bundles. The leading edges of such earthward‐moving flux bundles are called dipolarization fronts (DF). In the present study we investigate the characteristics of ion‐scale oscillations embedded inside DFs, using observations from NASA's ...

Toward a Dynamic Model for Topside Ionospheric Irregularities: Spherical Harmonic Decomposition

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Ionospheric irregularities arise from highly dynamic and turbulent processes related to magnetosphere‐ionosphere coupling and can lead to electromagnetic signal distortion or loss of lock events in global navigation satellite system signals, representing a hazard associated with space weather events. For this reason, understanding and modeling

Machine Learning‐Ready Data Sets for the Analysis and Nowcasting of Atmospheric Radiation at Aviation Altitudes

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Nowcasting and forecasting of the radiation environment in the Earth's lower atmosphere are critical for the safety of aircraft and spacecraft crews and passengers. Currently, this problem is addressed by employing statistical and physics‐based models that take into account particle transport and precipitation.
