Matroid products in tropical geometry

open access: yesResearch in the Mathematical Sciences
Symmetric powers of matroids were first introduced by Lovasz and Mason in the 1970s, where it was shown that not all matroids admit higher symmetric powers. Since these initial findings, the study of matroid symmetric powers has remained largely unexplored.

Combustion Properties of Timber in Historic Structures: Case Study of the São Pedro de Alcântara Chapel Fire

open access: yesFire and Materials, EarlyView.
ABSTRACT Timber plays a fundamental role in the fire performance of historic building components, where ageing and environmental exposure can markedly influence its physical and chemical properties. This study presents an experimental investigation of the fire behaviour of Ocotea sp.

Khovanskii bases, Newton-Okounkov polytopes and tropical geometry

open access: yes, 2017
I will talk about a recent work with Chris Manon giving a direct relation between the theory of Newton-Okounkov bodies (which is concerned with full rank valuations on a graded algebra) and tropical geometry (which is concerned with rank 1 valuations ...

Phytochemistry, Chemotypic Diversity and Antimicrobial Potential of Essential Oils From Native Aromatic Plants of the Americas: A Systematic Review

open access: yesFlavour and Fragrance Journal, EarlyView.
This review bridges ancestral indigenous knowledge with modern pharmacology, summarizing the phytochemistry and antimicrobial properties of essential oils from seven native American species. It highlights their significant activity against bacterial, fungal and parasitic pathogens, emphasizing their potential as sustainable therapeutic and agricultural

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

open access: yesFlexMat, 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.

Simultaneous 3/4‐power scaling of leaf mass and 2/3‐power scaling of leaf area with stem mass in plants

open access: yesGrassland Research, EarlyView.
Abstract Background Plant allometry theory developed in the last century focused on 2/3‐power scaling, determined by light interception considerations. More recently, 3/4‐power scaling based on the properties of vascular distribution networks has been proposed.

Clouds, Circulation, and Climate Sensitivity in a Radiative‐Convective Equilibrium Channel Model

open access: yesJournal of Advances in Modeling Earth Systems, 2017
Tropical cloud and circulation changes are large sources of uncertainty in future climate change. This problem owes partly to the scale separation between large‐scale tropical dynamics ( ∼104 km) and convective dynamics ( ∼1 km), which generally requires
