Determination of association constants between 5 '-guanosine monophosphate gel and aromatic compounds by capillary electrophoresis [PDF]

open access: yes, 2013
Hydro gel formed by 5'-guanosine monophosphate (GMP) in the presence of a potassium ion is expected to exhibit interesting selectivity in capillary electrophoretic separations.

On the variety associated to the ring of theta constants in genus 3 [PDF]

open access: greenAmerican Journal of Mathematics, 2016
Due to fundamental results of Igusa and Mumford the $N=2^{g-1}(2^g+1)$ even theta constants define for each genus $g$ an injective holomorphic map of the Satake compactification $X_g(4,8)=H_g/ _g[4,8]$ into the projective space $P^{N-1}$. Moreover, this map is biholomorphic onto the image outside the Satake boundary.

Interpolation inequalities and spectral estimates for magnetic operators [PDF]

open access: yes, 2018
We prove magnetic interpolation inequalities and Keller-Lieb-Thir-ring estimates for the principal eigenvalue of magnetic Schr{\"o}dinger operators. We establish explicit upper and lower bounds for the best constants and show by numerical methods that ...

The fusion algebra of bimodule categories [PDF]

open access: yes, 2007
We establish an algebra-isomorphism between the complexified Grothendieck ring F of certain bimodule categories over a modular tensor category and the endomorphism algebra of appropriate morphism spaces of those bimodule categories.

Double Split-Ring Resonator for Dielectric Constant Measurement of Solids and Liquids [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2022
This study proposes a 2.45-GHz double split-ring resonator for measuring the dielectric constant in both solids and liquids. Two concentric rectangular rings with asymmetric splits are used in the proposed resonator to achieve a high-quality factor for ...

Mobi algebra as an abstraction to the unit interval and its comparison to rings [PDF]

open access: yes, 2018
We introduce a new algebraic structure, called mobi algebra, consisting of three constants and one ternary operation. The canonical example of a mobi algebra is the unit interval with the three constants 0, 1, and 1/2 and the ternary operation given by ...

Determination of Acid Dissociation Constants (pKa) of Bicyclic Thiohydantoin-Pyrrolidine Compounds in 20% Ethanol-Water Hydroorganic Solvent

open access: yesInternational Journal of Analytical Chemistry, 2014
The acid dissociation constants of potential bioactive fused ring thiohydantoin-pyrrolidine compounds were determined by potentiometric titration in 20% (v/v) ethanol-water mixed at 25±0.1°C, at an ionic background of 0.1 mol/L of NaCl using the ...

Gauge invariants, correlators and holography in bosonic and fermionic tensor models

open access: yesJournal of High Energy Physics, 2017
Motivated by the close connection of tensor models to the SYK model, we use representation theory to construct the complete set of gauge invariant observables for bosonic and fermionic tensor models. Correlation functions of the gauge invariant operators

Optical appearance of Einstein-Æther black hole surrounded by thin disk

open access: yesNuclear Physics B, 2022
In Einstein-Æther theory, the Lorentz symmetry is locally broken in the high-energy regime due to the presence of the Æther field. This shall leave significant imprint on astronomical observation.
