Synthesis and Biological Evaluation of Azamacrolide Comprising the Triazole Moiety as Quorum Sensing Inhibitors

open access: yesMolecules, 2018
Novel azamacrolides comprising the triazole moiety were synthesized and evaluated for their quorum sensing inhibitor activities on the Agrobacterium tumefaciens. It was found that the inhibition rate of compound Z12-3 at 200 mg/L (0.45 mM) can reach 67%.

Aberration changes of the corneal anterior surface following discontinued use of rigid gas permeable contact lenses

open access: yesInternational Journal of Ophthalmology, 2013
AIM: To record aberrations with a corneal topographic device on the anterior surface of the cornea at different time-points prior to wearing and following discontinued use of rigid gas permeable (RGP) contact lenses.

Morphologies of Galaxies at z ≳ 9 Uncovered by JWST/NIRCam Imaging: Cosmic Size Evolution and an Identification of an Extremely Compact Bright Galaxy at z ∼ 12

open access: yesThe Astrophysical Journal, 2023
We present morphologies of galaxies at z ≳ 9 resolved by JWST/NIRCam 2–5 μ m imaging. Our sample consists of 22 galaxy candidates identified by stringent dropout and photo- z criteria in GLASS, CEERS, SMACS J0723, and Stephan’s Quintet flanking fields ...

Isolation and Characterization of Plant Growth-Promoting Bacteria from the Rhizosphere of Chamaecytisus ruthenicus (Russian Broom) Growing in Chalky Soil

open access: yesEngineering Proceedings, 2023
Plant growth-promoting (PGPR) bacteria are beneficial soil bacteria that enhance plant growth against biotic and abiotic stress. Numerous studies have been carried out over the past three decades on the isolation and characterization of rhizospheric ...

Elliptic U(2) quantum group and elliptic hypergeometric series

open access: yes, 2003
We investigate an elliptic quantum group introduced by Felder and Varchenko, which is constructed from the $R$-matrix of the Andrews-Baxter-Forrester model, containing both spectral and dynamical parameter.

Slowly driven sandpile formation with granular mixtures [PDF]

open access: yes, 1997
We introduce a one-dimensional sandpile model with $N$ different particle types and an infinitesimal driving rate. The parameters for the model are the N^2 critical slopes for one type of particle on top of another. The model is trivial when N=1, but for

Z_{12-I} Orbifold Compactification toward SUSY Standard Model

open access: yes, 2007
We explain the orbifold compactification in string models and present a Z_{12-I} orbifold compactification toward supersymmetric standard models. We also point out an effective R-parity from this string construction. The VEVs of gauge singlets are chosen

Entanglement, Replicas, and Thetas

open access: yes, 2018
We compute the single-interval Renyi entropy (replica partition function) for free fermions in 1+1d at finite temperature and finite spatial size by two methods: (i) using the higher-genus partition function on the replica Riemann surface, and (ii) using

Seiberg-Witten for $Spin(n)$ with Spinors [PDF]

open access: yes, 2014
$\mathcal{N}=2$ supersymmetric $Spin(n)$ gauge theory admits hypermultiplets in spinor representations of the gauge group, compatible with $\beta\leq0$, for $n\leq 14$.

The Full Structure of Quantum $N=2$ Super-$W_3^{(2)}$ Algebra

open access: yes, 1995
We present the complete structure of the nonlinear $N=2$ super extension of Polyakov-Bershadsky, $W_3^{(2)}$, algebra with the generic central charge, $c$, at the {\it quantum} level. It contains extra two pairs of fermionic currents with integer spins 1
