Sequential Patterning of Photoresponsive Hydrogels Directs Crypt Fission and Reveals the Role of Epithelial Curvature on Fission Symmetry

Advanced Science, EarlyView.
Deterministic crypt fission is achieved in intestinal organoids using photopatternable hydrogels with spatiotemporal control. Daughter‐crypt symmetry is shown to depend on parent‐crypt geometry and epithelial curvature, while myosin‐dependent mechanosensing links tissue shape to regenerative outcomes.

Achieving High‐Instantaneous Pulse Power in Contact‐Separation TENG via Series Capacitive Voltage Control Architecture

Advanced Science, EarlyView.
Conventional contact‐separation triboelectric nanogenerators generate high voltage but deliver limited power due to premature charge dissipation. Here, a capacitive charge reservoir architecture decouples charge accumulation from discharge triggering, enabling sequential voltage amplification via floating‐layer capacitive coupling.

Molecular Bases and Genetic Design of Rice Disease Resistance for Optimized Yield and Sustainable Agriculture

Advanced Science, EarlyView.
This study integrates rice immune perception, signal transduction, and resistance output into a multi‐omics framework. By combining high‐throughput sequencing, phenomics, and AI‐assisted design with marker‐assisted selection, gene editing, and rapid domestication, we aim to accelerate the precise breeding of disease‐resistant rice varieties by ...

Effets de labour et de non-labour en combinaison avec l'alimentation azotée sur le rendement du maïs (cv. SHABA I) [PDF]

Tropicultura, 1984
Effects of tillage and no-tillage with nitrogen nutrition on maize yield, (var Shaba I). The nitrogen was applied at the rates ranging from 0 to 80 kg/ha. The mean maize grain yield under no-tillage was 20 percent higher than under tillage.

Synergistic Integration of Fe–N4 Single‐Atom Sites and Directionally Aligned Electrode Architecture for High‐Performance Lithium–Sulfur Batteries

Advanced Science, EarlyView.
A directionally ice‐templated sulfur cathode integrated with atomically dispersed Fe–N4 catalytic sites is developed for high‐performance lithium–sulfur batteries. The structure–catalysis synergy accelerates Li+ transport and polysulfide conversion, leading to high sulfur utilization and stable long‐term cycling performance.

Soil fauna and its relation with environmental variables in soil management systems

Revista Ciência Agronômica
The present study aims to generate knowledge about the soil fauna, its relation to other explanatory environmental variables, and, besides it, to select edaphic indicators that more contribute to separate the land use systems (LUS).

Long and Midterm Effect of Conservation Agriculture on Soil Properties in Dry Areas of Morocco

Applied and Environmental Soil Science, 2016
In Morocco, conservation agriculture, particularly no tillage systems, has become an alternative strategy to mitigate land degradation caused by conventional tillage in semiarid to arid regions.

Dual Repression by IPA1 Fine‐Tunes OsbZIP79‐Mediated Salt Tolerance in Rice

Advanced Science, EarlyView.
Dual repression by IPA1 fine‐tunes OsbZIP79‐mediated salt tolerance in rice: direct transcriptional inhibition under normal conditions and salt‐induced degradation under stress. This dual mechanism activates OsbZIP79 to regulate Na+/K+ homeostasis and redox balance via downstream genes, enabling optimal salt stress response.
