Transforming Epilepsy Care: A Comprehensive Review of Technological Innovations, Artificial Intelligence Advancements, and Precision Tools for Enhanced Seizure Management and Patient Outcomes

open access: yesScientifica, Volume 2026, Issue 1, 2026.
Epilepsy is a neurological disorder characterized by repeated, unprovoked seizures arising from abnormal electrical activity in the brain. The management of epilepsy presents several significant challenges. One of these challenges involves drug resistance, where seizures persist despite treatment with multiple antiepileptic drugs, requiring a tailored ...

Biochar as a Strategy to Mitigate Greenhouse Gases in Degraded Drylands of the Brazilian Semiarid Region: Carbon Stocks and CO2 Fluxes

open access: yesJournal of Plant Nutrition and Soil Science, Volume 188, Issue 6, Page 1014-1026, December 2025.
This study evaluated the effects of pyrolytic biochars derived from co‐pyrolyzed sewage sludge and cashew residues on total organic carbon (TOC) recovery and CO2 emissions in degraded soils under greenhouse conditions. Biochar applications (5 to 40 Mg ha−1) enhanced soil carbon stocks and variably influenced CO2 fluxes over time.

Nonlinear Distortion Equalization in Multi‐Span Optical Links Via a Feed‐Forward Photonic Neural Network

open access: yesLaser &Photonics Reviews, Volume 19, Issue 23, December 3, 2025.
A feed‐forward photonic neural network equalizes linear and nonlinear impairments in multi‐span IMDD optical fiber transmission. The linear processing stage employs an 8‐tap optical Finite Impulse Response filter integrated on a silicon photonics platform, while the end‐of‐line photodetector represents the nonlinear stage.
