Arc-continent collisions in the tropics set Earth’s climate state

open access: yesScience, 2019
Controlling cooling On million-year time scales, Earth's climate state is determined by sources and sinks of carbon to the ocean-atmosphere system. But which specific mechanisms are important in controlling the timing of glacial intervals?

Tropical Sprue [PDF]

open access: yesSpringer Seminars in Immunopathology, 1990
It is surprising that in the gastrointestinal tract, with a primary barrier function and a large population of immunocytes, a major role for immunological damage has been convincingly established only for a few diseases; pernicious anaemia, gluten-sensitive enteropathy and GVHD.

Constraints on the age and dilution of Pacific Exploratory Mission-Tropics biomass burning plumes from the natural radionuclide tracer 210Pb [PDF]

open access: yes, 1999
During the NASA Global Troposphere Experiment Pacific Exploratory Mission-Tropics (PEM-Tropics) airborne sampling campaign we found unexpectedly high concentrations of aerosol-associated 210Pb throughout the free troposphere over the South Pacific ...

Field Technique and Traits to Assess Reproductive Stage Cold Tolerance in Sorghum (Sorghum bicolor (L.) Moench

open access: yesPlant Production Science, 2014
Post-rainy season sorghum (Sorghum bicolor (L.) Moench) yields are often constrained by cold stress. Cold tolerance is a prerequisite for adaptation to post-rainy season.

Plant vigour QTLs co-map with an earlier reported QTL hotspot for drought tolerance while water saving QTLs map in other regions of the chickpea genome

open access: yesBMC Plant Biology, 2018
Background Terminal drought stress leads to substantial annual yield losses in chickpea (Cicer arietinum L.). Adaptation to water limitation is a matter of matching water supply to water demand by the crop.

Genetic mapping identified major main‐effect and three co‐localized quantitative trait loci controlling high iron and zinc content in groundnut

open access: yesThe Plant Genome, 2023
Malnutrition is a major challenge globally, and groundnut is a highly nutritious self‐pollinated legume crop blessed with ample genomic resources, including the routine deployment of genomic‐assisted breeding. This study aimed to identify genomic regions

Genetic approaches for assessment of phosphorus use efficiency in groundnut (Arachis hypogaea L.)

open access: yesScientific Reports, 2022
Production of phosphorus efficient genotypes in groundnut can improve and also reduces environmental pollution. Identification of P-efficient groundnut genotypes is a need of the hour to sustain in P-deficient soils. The pot experiment showed significant

Tropical Linear Spaces and Tropical Convexity [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2015
In classical geometry, a linear space is a space that is closed under linear combinations. In tropical geometry, it has long been a consensus that tropical varieties defined by valuated matroids are the tropical analogue of linear spaces. It is not difficult to see that each such space is tropically convex, i.e.

Single Seed-Based High-Throughput Genotyping and Rapid Generation Advancement for Accelerated Groundnut Genetics and Breeding Research

open access: yesAgronomy, 2021
The groundnut breeding program at International Crops Research Institute for the Semi-Arid Tropics routinely performs marker-based early generation selection (MEGS) in thousands of segregating populations.

Neglected Tropical Diseases outside the Tropics

open access: yesPLoS Neglected Tropical Diseases, 2010
The neglected tropical diseases (NTDs) cause significant morbidity and mortality worldwide. Due to the growth in international travel and immigration, NTDs may be diagnosed in countries of the western world, but there has been no specific focus in the literature on imported NTDs.Retrospective study of a cohort of immigrants and travelers diagnosed with
