Quantum cohomology of the Lagrangian Grassmannian
Let V be a symplectic vector space and LG be the Lagrangian Grassmannian which parametrizes maximal isotropic subspaces in V. We give a presentation for the (small) quantum cohomology ring QH^*(LG) and show that its multiplicative structure is determined

A note on characterizations of rings of constants with respect to derivations [PDF]
Summary: Let \(A\) be a commutative algebra without zero divisors over a field \(k\). If \(A\) is finitely generated over \(k\), then there exist well known characterizations of all \(k\)-subalgebras of \(A\) which are rings of constants with respect to \(k\)-derivations of \(A\) [see e.g. \textit{P. Jȩdrzejewicz}, Commun.

We use the linear sigma model coupled to quarks, together with a plausible location of the critical end point (CEP), to study the chiral symmetry transition in the QCD phase diagram. We compute the effective potential at finite temperature and density up

Photonic Crystal Fiber Modal Interferometer for Refractive Index Sensing
We present a modification of core-cladding intermodal interferometer for refractive index sensing. Its structure consists of double cladding photonic crystal fiber (PCF) as a sensing element.

Rings and fields of constants for derivations in characteristic zero
Let \(K\) be a field of characteristic zero and \(L\) be a field extension of \(K\). \textit{S. Suzuki} [J. Math. Kyoto Univ. 21, 375--382 (1981; Zbl 0496.12018)] and \textit{J. Derksen} [Report 9123, Catholic Univ. Nijmegen (1991)] have shown that if \(L\) has finite transcendence degree and \(F\) is an intermediate field between \(K\) and \(L\), then

Strain rotation coupling and its implications on the measurement of rotational ground motions [PDF]
Spatial derivatives of the seismic wave field are known to be sensitive to various site effects (e.g., cavity effects, topography, and geological inhomogeneities).

Picolinic acid promoted oxidative decarboxylation of phenylsulfinylacetic acid by Cr(VI)
The kinetics and mechanism of picolinic acid promoted reaction of phenylsulfinylacetic acid (PSAA) with Cr(VI) was carried out in aqueous acetonitrile medium under pseudo first order conditions. The reaction follows Michaelis-Menten type of kinetics with

Tropospheric Degradation of Perfluorinated Aromatics: A Case of Hexafluorobenzene
The major tropospheric removal process for hexafluorobenzene is its oxidation by hydroxyl (OH) radicals. However, there is no information on the reaction mechanism of this important process.

Coordination Chemistry of Glycolic Acid and Uranyl
Glycolic acid (α-hydroxyacetic acid, HA) is a simple, water-soluble carboxylic acid ligand commonly found in the environment. It can coordinate with metal ions through both its carboxyl and hydroxyl oxygen atoms.
