Point line geometry in the tropical plane

Collectanea Mathematica, 2022
AbstractWe study the classical result by Bruijn and Erdős regarding the bound on the number of lines determined by a n-point configuration in the plane, and in the light of the recently proven Tropical Sylvester-Gallai theorem, come up with a tropical version of the above-mentioned result. In this work, we introduce stable tropical lines, which help in

Counter‐ion modulation: A facile approach toward quenching‐resistant multi‐resonance emitters for efficient narrowband electroluminescence

FlexMat, EarlyView.
Quenching‐resistant carbocation‐based multi‐resonance emitters are developed via a facile counter‐ion modulation strategy, giving much narrowed emission bands under high doping concentrations, and greatly improved device efficiency for solution‐processed narrowband OLEDs by simply increasing the size of counter ions.

The interacting effects of ungulate hoofprints and predatory native ants on metamorph cane toads in tropical Australia.

PLoS ONE, 2013
Many invasive species exploit the disturbed habitats created by human activities. Understanding the effects of habitat disturbance on invasion success, and how disturbance interacts with other factors (such as biotic resistance to the invaders from the ...

Phytochemical profiling and bioactivity evaluation of Anthocephalus cadamba flower extracts through in vitro, and in silico studies

Food Biomacromolecules, EarlyView.
Abstract Anthocephalus cadamba (Kadamba) is a medicinally important tropical plant with well‐documented antioxidant, anti‐inflammatory, and antimicrobial properties. However, comparative evaluation of solvent extraction efficiency combined with computational validation of bioactive compounds remains limited.

Hurwitz Trees and Tropical Geometry [PDF]

, 2016
The lifting problem in algebraic geometry asks when a finite group G acting on a curve defined over characteristic p > 0 lifts to characteristic 0. One object used in the study of this problem is the Hurwitz tree, which encodes the ramification data of

Somatosensory Disturbance and Long‐Term Exposure to Methylmercury: A Comprehensive Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Chronic exposure to methylmercury remains a significant public health concern, particularly in populations with high fish consumption. Somatosensory disturbances are among the most frequently reported neurological manifestations, even at exposure levels below internationally established safety thresholds. This review aims to synthesize current

Semiring Congruences and Tropical Geometry [PDF]

, 2016
One of the main motivations and inspirations for this thesis is the still open question of the definition of geometry in characteristic one. This is geometry over a structure, called an idempotent semiring, in which 1+1 = 1.

Geometric Monodromy around the Tropical Limit [PDF]

, 2016
Let {Vq}q be a complex one-parameter family of smooth hypersurfaces in a toric variety. In this paper, we give a concrete description of the monodromy transformation of {Vq}q around q=∞ in terms of tropical geometry.

Exploring the optimal geometry of satellites Himawari-8/9 to monitor seasonal variation in vegetation dynamics across Southeast Asia

Environmental Research Letters
Dense and widespread tropical rainforests across Southeast Asia are crucial for the global carbon cycle. A new generation geostationary satellite, Himawari-8/9, and onboard sensor, the Advanced Himawari Imager (AHI), enables hyper-temporal vegetation ...
