Retrieval of stratospheric aerosol size distribution parameters using satellite solar occultation measurements at three wavelengths [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
In this work, a novel approach for the determination of the particle size distribution (PSD) parameters of stratospheric sulfate aerosols is presented. For this, ratios of extinction coefficients obtained from SAGE III/ISS (Stratospheric Aerosol and Gas ...

Solid Phase Assembly of Fully Protected Trinucleotide Building Blocks for Codon-Based Gene Synthesis

open access: yesApplied Sciences, 2019
The use of pre-formed trinucleotides, representing codons of the 20 canonical amino acids, for oligonucleotide-directed mutagenesis offers the advantage of controlled randomization and generation of “smart libraries”. We here present a method

Compactification of closed preordered spaces [PDF]

open access: yes, 2012
A topological preordered space admits a Hausdorff closed preorder compactification if and only if it is Tychonoff and the preorder is represented by the family of continuous isotone functions.

Synthesis of Seven Indolizine-Derived Pentathiepines: Strong Electronic Structure Response to Nitro Substitution in Position C-9

open access: yesMolecules, 2023
Seven new 1,2,3,4,5-pentathiepino[6,7-a]indolizines were synthesized in which the pentathiepine moieties bear an indolizine backbone that is derivatized from C–H to F-, Cl-, Br-, I-, NO2-, and CH3-substitutions, respectively, in a meta position relative ...

The Fell compactification and non-Hausdorff groupoids [PDF]

open access: yes, 2009
A compactification of Fell is applied to locally compact non-Hausdorff groupoids and yields locally compact Hausdorff groupoids. In the etale case, this construction provides a geometric picture for the left-regular representations introduced by Khoshkam

Antimicrobial effects of microwave‐induced plasma torch (MiniMIP) treatment on Candida albicans biofilms

open access: yesMicrobial Biotechnology, 2019
Summary The susceptibility of Candida albicans biofilms to a non‐thermal plasma treatment has been investigated in terms of growth, survival and cell viability by a series of in vitro experiments. For different time periods, the C. albicans strain SC5314

A sharp nonlinear Hausdorff-Young inequality for small potentials [PDF]

open access: yes, 2018
The nonlinear Hausdorff-Young inequality follows from the work of Christ and Kiselev. Later Muscalu, Tao, and Thiele asked if the constants can be chosen independently of the exponent.

Controlling the direction of topological transport in a non-Hermitian time-reversal symmetric Floquet ladder

open access: yesAPL Photonics, 2021
We propose a one-dimensional Floquet ladder that possesses two distinct topological transport channels with opposite directionality. The transport channels occur due to a Z2 non-Hermitian Floquet topological phase that is protected by time-reversal ...

Pre-Hausdorff spaces

open access: yesPublicationes Mathematicae Debrecen, 2008
This paper introduces three separation conditions for topological spaces, called T_{0,1}, T_{0,2} ("pre-Hausdorff"), and T_{1,2}. These conditions generalize the classical T_(1) and T_(2) separation axioms, and they have advantages over them topologically which we discuss.

FPT-Algorithms for Computing Gromov-Hausdorff and Interleaving Distances Between Trees [PDF]

open access: yes, 2019
The Gromov-Hausdorff distance is a natural way to measure the distortion between two metric spaces. However, there has been only limited algorithmic development to compute or approximate this distance.
