Validation of sorghum quality control (QC) markers across African breeding lines

open access: yesThe Plant Genome
Sorghum [Sorghum bicolor (L.) Moench] is a cereal crop of critical importance in the semi‐arid tropics, particularly in Africa where it is second only to maize (Zea mays L.) by area of cultivation.

Light and Dark Cycles Control the Structural Evolution of Photoresponsive Supramolecular Systems

open access: yesAngewandte Chemie, EarlyView.
Here, we report a photoswitchable synthetic peptide that, under light energy cycles, exhibits supramolecular polymorphism coupled to darkness‐driven structural self‐selection. We demonstrate that light sustains a transient assembled state in the form of helical nanoribbons, hindering the system from undergoing a transition to the disassembled state ...

Factorization Machine‐Based Active Learning for Functional Materials Design with Optimal Initial Data

open access: yesAdvanced Intelligent Discovery, EarlyView.
This work investigates the optimal initial data size for surrogate‐based active learning in functional material optimization. Using factorization machine (FM)‐based quadratic unconstrained binary optimization (QUBO) surrogates and averaged piecewise linear regression, we show that adequate initial data accelerates convergence, enhances efficiency, and ...

Environmental Identification of Novel Enzymes for Polyurethane and Polyamide Degradation

open access: yesAngewandte Chemie, EarlyView.
Heteroatom‐containing plastics such as polyurethanes and nylons are produced at scale yet remain largely unrecycled. Biocatalysts offer a promising route to depolymerization under mild conditions. Here, we present a screening platform for the discovery of novel polyurethane‐ and nylon‐degrading enzymes from environmental samples and demonstrate ...

Off-farm income, risk, and agricultural production: a case study of smallholders in India's semi-arid tropics

open access: yes, 2001
The purpose of the current study was to determine to what extent development of the nonfarm sector stimulates crop production and agricultural employment in India's semi-arid tropics (SAT).

Proceedings of the Internat ional Workshop on the Agrocl imatological Research Needs of the Semi-Arid Tropics [PDF]

open access: yes, 1978
In the semi-arid tropics high and sustained agricultural production is hampered by many natural const raints. The SAT farmer mus t cope with the vagaries of a rainy season that is shor t and highl y unpredictable; intense rainfall interspersed with ...

The IL‐10/IL‐6 Ratio and the Risk Score: Two Cytokines‐Based Predictors for Malignancy‐Associated Hemophagocytic Lymphohistiocytosis in Adults (M‐HLHa)

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT The predictive value of cytokines (CK) for malignancy‐associated adult hemophagocytic lymphohistiocytosis (M‐HLHa) remains uncertain. We evaluated a cytokine‐based Risk Score (RS) and the IL‐10/IL‐6 Ratio to predict M‐HLHa. Adult patients (n = 112) from the French HLH cohort (NCT02113917) with complete data for nine key HLH related CK measured

Thermostable Bioluminescent Intercalating Dyes for Real‐Time, Integrated Nucleic Acid Amplification and Detection

open access: yesAngewandte Chemie, EarlyView.
We present a bioluminescent diagnostic platform that integrates DNA amplification and detection in a single step. The engineering of thermostable luciferase‐intercalating dye conjugates and controlled release of caged luciferin substrates enable real‐time, detection of attomolar concentrations of viral DNA within 30 min.

The papaw : a fruit for the tropics and sub-tropics

open access: yes, 1962
TOE fruit of the papaw (Carica papaya) has a unique flavour and is a welcome addition to any diet. In the tropics and sub-tropics the papaw is quite easy to grow and is adapted to a wide range of soils and ...
