Kinetic parameter prediction using neural networks identifies limitations to C4 photosynthesis

New Phytologist, Volume 251, Issue 3, Page 1578-1594, August 2026.
Schematic overview of the generation of artificial training data and training of neural networks in C4TUNE. Summary Kinetic models of photosynthesis enable time‐resolved predictions of traits related to this key process and provide the means to identify factors limiting photosynthesis.

The Intersection of Human Rights, HIV and Sex Work: Implications for Ending AIDS in Thailand by 2030

Journal of the International AIDS Society, Volume 29, Issue 7, July 2026.
ABSTRACT Introduction Sex work significantly shapes the Thai economy and the HIV epidemic, yet its criminalization restricts access to health services and exacerbates human rights violations. This study examines experiences of stigma, discrimination, gender‐based violence (GBV) and incarceration among sex workers (SWs), exploring how these factors ...

Diversity Analysis of Distributed Space-Time Codes in Relay Networks with Multiple Transmit/Receive Antennas

EURASIP Journal on Advances in Signal Processing, 2008
The idea of space-time coding devised for multiple-antenna systems is applied to the problem of communication over a wireless relay network, a strategy called distributed space-time coding, to achieve the cooperative diversity provided by antennas of the

Pretesting and Posttesting in Spelling Acquisition: Cross‐Linguistic Evidence From Contrasting Writing Systems

Applied Cognitive Psychology, Volume 40, Issue 3, May/June 2026.
ABSTRACT Understanding how cognitive mechanisms support spelling acquisition across writing systems is a fundamental challenge in educational psychology. We conducted the first controlled comparison of pretesting (generating spellings before instruction), posttesting (retrieving spellings after instruction), and copying (traditional transcription ...

S2‐PepAnalyst: A Web Tool for Predicting Plant Small Signalling Peptides

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3244-3260, May 2026.
ABSTRACT Small signalling peptides (SSPs) serve as crucial mediators of cell‐to‐cell communication in plants, orchestrating diverse physiological processes from development to stress responses. While recent advances in sequencing technologies have improved genome annotation, the identification of novel SSPs remains challenging due to their small size ...

Designing networks of freshwater and marine conservation areas accounting for cross‐realm connectivity and threat propagation

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
This study highlights the importance of integrating cross‐realm connectivity and threat propagation when designing new or expanding existing networks of conservation areas, such as the Natura 2000 European network of protected areas. These findings emphasize the need for multirealm planning that supports species persistence, protects transitional ...

Comparative Analysis of Deep Learning‐Based Algorithms for Peptide Structure Prediction

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 3, Page 675-691, March 2026.
ABSTRACT While of primary importance in both the biomedical and therapeutic fields, peptides suffer from a relative lack of dedicated tools to predict efficiently and accurately their 3D structures despite being a crucial step in understanding their physio‐pathological function or designing new drugs. In recent years, deep‐learning methods have enabled
