Multiplicative structure of 2x2 tropical matrices

, 2009
We study the algebraic structure of the semigroup of all $2 \times 2$ tropical matrices under multiplication. Using ideas from tropical geometry, we give a complete description of Green's relations and the idempotents and maximal subgroups of this ...

Critical Review on the Molecular Behavior of Surfactants at the Oil–Water Interface During Oil Displacement

Energy Science &Engineering, EarlyView.
This review systematically explores the molecular behavior of diverse surfactants (anionic, cationic, nonionic, amphoteric) at the oil–water interface through molecular dynamics simulations. It highlights their roles in reducing interfacial tension, altering interfacial structure, and enhancing oil recovery efficiency.

Development of an Innovative and Functional Yerba Mate—Lychee Beverage: Sensory and Physicochemical Characteristics

Food Safety and Health, EarlyView.
A mixed beverage of yerba mate and lychee was developed and optimized. The 70:30 lychee‐to‐mate formulation provided the best balance of antioxidant activity and consumer acceptance, highlighting its potential as a functional beverage. ABSTRACT The development of functional beverages that combine bioactive compounds with sensory appeal is of growing ...

Amoebas of algebraic varieties and tropical geometry

, 2004
This survey consists of two parts. Part 1 is devoted to amoebas. These are images of algebraic subvarieties in the complex torus under the logarithmic moment map. The amoebas have essentially piecewise-linear shape if viewed at large.
