Composing Scalable Nonlinear Algebraic Solvers [PDF]
, 2015 Most efficient linear solvers use composable algorithmic components, with the most common model being the combination of a Krylov accelerator and one or more preconditioners.

Superparamagnetic nanoadsorbents for the removal of trace As(III) in drinking water
Environmental Advances, 2021 A series of novel zeolitic imidazolate framework (ZIF) decorated superparamagnetic graphene oxide hybrid nanoadsorbents were synthesized, characterized, and tested for their As(III) adsorbed amount in simulated drinking water.

Monotone Projection Lower Bounds from Extended Formulation Lower Bounds [PDF]
, 2017 In this short note, we reduce lower bounds on monotone projections of polynomials to lower bounds on extended formulations of polytopes. Applying our reduction to the seminal extended formulation lower bounds of Fiorini, Massar, Pokutta, Tiwari, & de ...

Computing low-degree factors of lacunary polynomials: a Newton-Puiseux approach [PDF]
, 2014 We present a new algorithm for the computation of the irreducible factors of degree at most $d$, with multiplicity, of multivariate lacunary polynomials over fields of characteristic zero.

A dynamic look-ahead Monte Carlo algorithm for pricing Bermudan options [PDF]
, 2007 Under the assumption of no-arbitrage, the pricing of American and Bermudan options can be casted into optimal stopping problems. We propose a new adaptive simulation based algorithm for the numerical solution of optimal stopping problems in discrete time.

Sex pheromones in amphibians: a review
Veterinární Medicína, 2005 Amphibians are interesting animals, very often kept by aquarists and vivarists. Their ability of intraspecific chemical signalization belongs to very interesting biological features.

The application of eDNA for monitoring of the great crested newt in the UK [PDF]
, 2014 Current ecological surveys for great crested newts are time-consuming and expensive and can only be carried out within a short survey window. Additional survey methods which would facilitate the detection of rare or protected species such as the great ...

Laminar flow in three-dimensional square-square expansions [PDF]
, 2011 In this work we investigate the three-dimensional laminar flow of Newtonian and viscoelastic fluids through square–square expansions. The experimental results obtained in this simple geometry provide useful data for benchmarking purposes in complex three-

Comparative transcriptomic analysis and structure prediction of novel Newt proteins.
PLoS ONE, 2019 Notophthalmus viridescens (Red-spotted Newt) possess amazing capabilities to regenerate their organs and other tissues. Previously, using a de novo assembly of the newt transcriptome combined with proteomic validation, our group identified a novel family
