Advanced Science, EarlyView.Inspired by the twin grain boundary discovered in natural gyroidal networks, a series of gyroid‐derived photonic crystals are constructed based on defect‐symmetry engineering. The new series of structures enables monotonic tuning of the width of the photonic bandgap (PBG) while the central frequency of the PBG maintains stable.

Forecasting Wheat Output and Profits from Cropping Systems Using Simulation Models in Uasin Gishu, Kenya [PDF]
Simulation models have been used successfully to forecast productivity of cropping systems under various weather, management and policy scenarios. These models have helped farmers make efficient resource allocation decisions. However, in Kenya simulation

Advanced Science, EarlyView.An eight‐stream 2.5D Transformer integrates complementary PET metabolic and CT morphologic information to estimate spread‐through‐air‐spaces risk before surgery in lung adenocarcinoma. The model generalizes across independent centers, while its continuous risk score independently stratifies progression‐free survival, supporting further prospective ...

Risk Analysis of Organic Cropping Systems in Minnesota [PDF]
When all strategies received conventional market prices, 4-year cropping sequences had greater net returns than 2-year sequences, and the organic input, 4-year strategy had the highest net return.

LigHTS: Biomimetic Hydrogel Photo‐Fabrication for Imaging‐Based Ultra‐High‐Throughput Screening
Advanced Science, EarlyView.LigHTS removes a key bottleneck for ultra‐high‐throughput screening (UHTS) by enabling biomimetic hydrogel microenvironments to be manufactured directly in standard multiwell plates. A single, collimated UV exposure with formulation‐tuned light penetration patterns an entire plate with UHTS‐grade uniformity (<20% CV), producing structured GelMA films ...

Flooding‐Driven Greenhouse Gas Emissions From Global Upland Croplands
Advanced Science, EarlyView.Temporary flooding of upland croplands releases nitrous oxide, carbon dioxide, and methane. Field measurements combined with a global literature synthesis yield a global estimate of 63.3 teragrams of carbon dioxide equivalent per year for diffusive emissions from flooded upland croplands.

Yield stability in barley-wheat mixed cropping in Central Highlands of Eritrea
, 2008 Yield data of a large set of experiments with barley and wheat were analysed in order to assess whether yield stability was greater in mixed cropping than in sole cropping, and to identify which varietal mixture showed most stable grain yields.

Enriched Soil Organic Carbon Underpins Long‐Term Stable Crop Productivity Across China's Croplands
Advanced Science, EarlyView.Quantifying the nonlinear relationships and causal effects of soil organic carbon (SOC) on crop stability reveals specific critical thresholds and saturation points. This partitions the national SOC spectrum into three functional phases. Integrating these spatial delineations with high‐resolution maps of marginal gains pinpoints regions with the ...

Comparison of Risk Between Cropping Systems in Eastern Norway [PDF]
The aim of this study was to compare production and policy risk of organic, integrated and conventional cropping systems in Norway. Experimental cropping system data (1991-1999) from eastern Norway were combined with budgeted data.
