Tropical Ehrhart theory and tropical volume [PDF]

open access: yesResearch in the Mathematical Sciences, 2020
AbstractWe introduce a novel intrinsic volume concept in tropical geometry. This is achieved by developing the foundations of a tropical analog of lattice point counting in polytopes. We exhibit the basic properties and compare it to existing measures. Our exposition is complemented by a brief study of arising complexity questions.

Are Terrestrial Biological Invasions Different in the Tropics?

open access: yesAnnual Review of Ecology, Evolution and Systematics, 2021
Most biological invasion literature—including syntheses and meta-analyses and the resulting theory—is reported from temperate regions, drawing only minimally from the tropics except for some island systems.

Seasonal differences in the photochemistry of the South Pacific: A comparison of observations and model results from PEM-Tropics A and B [PDF]

open access: yes, 2001
A time-dependent photochemical box model is used to examine the photochemistry of the equatorial and southern subtropical Pacific troposphere with aircraft data obtained during two distinct seasons: the Pacific Exploratory Mission-Tropics A (PEM-Tropics ...

Identification and validation of selected universal stress protein domain containing drought-responsive genes in pigeonpea (Cajanus cajan L.)

open access: yesFrontiers in Plant Science, 2016
Pigeonpea is a resilient crop, which is relatively more drought tolerant than many other legume crops. To understand the molecular mechanisms of this unique feature of pigeonpea, 51 genes were selected using the Hidden Markov Models those codes for ...

Latitudinal, vertical, and seasonal variations of C-1-C-4 alkyl nitrates in the troposphere over the Pacific Ocean during PEM-Tropics A and B: Oceanic and continental sources [PDF]

open access: yes, 2003
We present concentration distributions of C1‐C4 alkyl nitrates observed during the NASA airborne campaigns Pacific Exploratory Mission (PEM) ‐Tropics A (September–October 1996) and PEM‐Tropics B (March–April 1999).

Factors controlling tropospheric O3, OH, NOx, and SO2 over the tropical Pacific during PEM-Tropics B [PDF]

open access: yes, 2001
Observations over the tropical Pacific during the Pacific Exploratory Mission (PEM)-Tropics B experiment (March-April 1999) are analyzed. Concentrations of CO and long-lived nonmethane hydrocarbons in the region are significantly enhanced due to ...

Tropical pyomyositis

open access: yesNorth American Journal of Medical Sciences, 2013
Tropical pyomyositis is characterized by suppuration within skeletal muscles, manifesting as single or multiple abscesses. Though primarily a disease of tropics, it is increasingly being reported from temperate regions in immunosuppressed patients. However, India has only few sporadic case reports.The aim of this study is to evaluate the causative ...
