A user-friendly Matlab program and GUI for the pseudorotation analysis of saturated five-membered ring systems based on scalar coupling constants [PDF]

open access: yes, 2008
Background: The advent of combinatorial chemistry has revived the interest in five-membered heterocyclic rings as scaffolds in pharmaceutical research. They are also the target of modifications in nucleic acid chemistry.

Equivariant Quantum Schubert Polynomials [PDF]

open access: yes, 2014
We establish an equivariant quantum Giambelli formula for partial flag varieties. The answer is given in terms of a specialization of universal double Schubert polynomials.

Development of a fluorescence polarization based high-throughput assay to identify Casitas B-lineage lymphoma RING domain regulators. [PDF]

open access: yesPLoS ONE, 2013
The E3 ubiquitin protein ligase Casitas B-lineage Lymphoma (Cbl) proteins and their binding partners play an important role in regulating signal transduction pathways. It is important to utilize regulators to study the protein-protein interactions (PPIs)

Binding Constants of Substituted Benzoic Acids with Bovine Serum Albumin

open access: yesPharmaceuticals, 2020
Experimental data on the affinity of various substances to albumin are essential for the development of empirical models to predict plasma binding of drug candidates. Binding of 24 substituted benzoic acid anions to bovine serum albumin was studied using

On the Structure of the Small Quantum Cohomology Rings of Projective Hypersurfaces

open access: yes, 1999
We give an explicit procedure which computes for degree $d \leq 3$ the correlation functions of topological sigma model (A-model) on a projective Fano hypersurface $X$ as homogeneous polynomials of degree $d$ in the correlation functions of degree 1 ...

Factorisation theorems for generalised power series [PDF]

open access: yes, 2017
Fields of generalised power series (or Hahn fields), with coefficients in a field and exponents in a divisible ordered abelian group, are a fundamental tool in the study of valued and ordered fields and asymptotic expansions.

Rings of Constants of the Formk[f] [PDF]

open access: yesCommunications in Algebra, 2006
Let k[X] be the algebra of polynomials in n variables over a field k of characteristic zero, and let f ∊ k[X]∖ k. We present a construction of a derivation d of k[X] whose ring of constants is equal to the integral closure of k[f] in k[X]. A similar construction for fields of rational functions is also given.

The kinetics of the reaction of 6-substituted nicotinic acids and some p-substituted benzoic acids with diazodiphenylmethane in various alcohols [PDF]

open access: yesJournal of the Serbian Chemical Society, 2000
Rate constants have been determined for the reactions of diazodiphenylmethane with a number of 6-substituted nicotinic acids and p-substituted benzoic acids in twelve alcohols. A comparative study was used to evaluate and compare the Hammett r values and

Simultaneous $p$-orderings and minimising volumes in number fields

open access: yes, 2016
In the paper "On the interpolation of integer-valued polynomials" (Journal of Number Theory 133 (2013), pp. 4224--4232.) V. Volkov and F. Petrov consider the problem of existence of the so-called $n$-universal sets (related to simultaneous $p$-orderings ...

High-Sensitivity Microwave Sensor Based on an Interdigital-Capacitor-Shaped Defected Ground Structure for Permittivity Characterization

open access: yesSensors, 2019
This study proposes a high-sensitivity microwave sensor based on an interdigital-capacitor-shaped defected ground structure (IDCS-DGS) in a microstrip transmission line for the dielectric characterization of planar materials.
