Comparing Remotely Sensed and Weather Station Measured Rainfall Data for Flood Prediction in KwaZulu Natal, South Africa

Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT Extreme rainfall events frequently trigger flash floods, which cause widespread damage to ecosystems, infrastructure, and livelihoods. Accurate rainfall estimation is therefore essential for flood modeling and early warning systems. This study assessed the performance of the Tropical Rainfall Measuring Mission (TRMM) and the Global ...

Image Encoding With Blipped Gradients in an Echo Train

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2530-2538, November 2026.
ABSTRACT Purpose An MRI scanner was designed and built to encode k‐space points in the spin echoes occurring between 180∘ pulses in an echo train by using blipped B0 gradient pulses applied just prior to those spin echoes. Methods The proposed MRI scanner is a modification of an original design that used TRansmit Array Spatial Encoding (TRASE), a built‐

Saline‐Water Irrigation Elicits Hormetic Yield Responses in Sweetpotato Across 28 Genotypes Under Field Conditions

Journal of Agronomy and Crop Science, Volume 212, Issue 6, November 2026.
ABSTRACT The use of saline water for irrigation is increasing as the quantity and quality of irrigation water resources are declining. Saline irrigation also provides a means to investigate crop responses to heterogenous salinity, which is a common occurrence in agricultural fields. Crop responses to salinity are dose‐ and genotype dependent, providing

Micro/Nanoscale Acoustic Manipulation: From Particle Control to Autonomous Microswimmers

Advanced Science, Volume 13, Issue 55, 5 October 2026.
This conceptual framework illustrates acoustic technology as a multifunctional platform enabling passive particle manipulation across scales and autonomous propulsion of microswimmers. ABSTRACT Acoustic manipulation and propulsion technologies have emerged as powerful platforms for micro/nanoscale control, enabled by their non‐contact operation, label ...

Utterance evolution: the road to generative, combinatorial communicators

Biological Reviews, Volume 101, Issue 5, Page 2427-2447, October 2026.
ABSTRACT Language has long been considered uniquely complex in the animal kingdom; however, animal research over the last decade has begun to challenge some long‐standing premises about exactly which language capacities are uniquely human. The task of resolving why and how complex communication systems evolve, particularly human language, has ...

A Mechanism for Analyzing the Energy Consumption and Environmental Impact of LoRa Sensors Over Time

International Journal of Communication Systems, Volume 39, Issue 15, October 2026.
An SPN‐based mechanism, validated against NS‐3 with MAPE below 0.3%, reveals how packet generation rate and spreading factor shape LoRa sensor lifetime, energy consumption, and operational CO2$$ {}_2 $$ emissions, supporting sustainable planning of large‐scale IoT deployments. ABSTRACT Long Range (LoRa) sensors are widely adopted in Internet of Things (

Study of a Frugal Design Picosecond Laser System for Laser‐Assisted Corneal Surgery

Journal of Biophotonics, Volume 19, Issue 10, October 2026.
Stromal surface after extraction of the lamella cut with the studied frugal picosecond laser source. ABSTRACT Femtosecond lasers have long been the gold standard for corneal laser‐assisted surgery, but their high cost limits widespread use. This study challenges their supremacy by investigating a cost‐effective alternative: a frugal all‐fiber ...
