Inhibition of Acinetobacter baumannii, Staphylococcus aureus and Pseudomonas aeruginosa biofilm formation with a class of TAGE-triazole conjugates
(Royal Society of Chemistry, 2009-01-12)A chemically diverse library of TAGE-triazole conjugates was synthesized utilizing click chemistry on the TAGE scaffold. This library of small molecules was screened for anti-biofilm activity and found to possess the ability ... -
Synthesis and bacterial biofilm inhibition studies of ethyl N-(2-phenethyl) carbamate derivatives
(Royal Society of Chemistry, 2010-07-08)An 88 member library based upon the marine bacterial metabolite ethyl N-(2-phenethyl) carbamate was evaluated for bacterial biofilm inhibition against a panel of medically relevant strains. These studies culminated in the ... -

Dynamical origin of near- and below-threshold harmonic generation of Cs in an intense mid-infrared laser field
(Nature Publishing Group, 2015)Near- and below-threshold harmonic generation provides a potential approach to generate vacuum-ultraviolet frequency comb. However, the dynamical origin of in these lower harmonics is less understood and largely unexplored. ... -
Whispering Gallery Mode Resonators for Rapid Label-Free Biosensing in Small Volume Droplets
(MDPI, 2015-03-23)Rapid biosensing requires fast mass transport of the analyte to the surface of the sensing element. To optimize analysis times, both mass transport in solution and the geometry and size of the sensing element need to be ... -
A new time-frequency method to reveal quatum dynamics of atomic hydrogen in intense laser pulses: Synchrosqueezing transform
(AIP publishing, 2014-11-26)This study introduces a new adaptive time-frequency (TF) analysis technique, the synchrosqueezing transform (SST), to explore the dynamics of a laser-driven hydrogen atom at an ab initio level, upon which we have demonstrated ... -
Calculation of the Green's function from high- and low-density series expansions for disordered transport
(American Physical Society, 1984-05-01)We investigate density expansions for the configurationally averaged Green's function for a random walk on a (site) disordered lattice. Two-point Padé summation techniques are used in conjunction with scaling arguments to ... -
Freezing of soft spheres: A critical test for weighted-density-functional theories
(American Physical Society, 1990-10-15)We study the freezing properties of systems with inverse-power and Yukawa interactions (soft spheres), using recently developed weighted-density-functional theories. We find that the modified weighted-density-functional ... -
Comparison of weighted-density-functional theories for inhomogeneous liquids
(American Physical Society, 1990-10-15)Three recent weighted-density-functional (WDF) theories are critically examined in terms of their ability to describe correctly the structure of a hard-sphere fluid at a hard wall. A new derivation of the Curtin-Ashcroft ... -
Localized low-frequency vibrational modes in a simple model glass
(American Physical Society, 1991-02-04)We examine the vibrational spectrum of a glass of soft spheres produced by quenching an equilibrated liquid (produced via constant-energy molecular-dynamics simulation) to zero temperature. Normal-mode analysis shows clearly ... -
Calculation of the entropy from multiparticle correlation functions
(American Physical Society, 1992-04-15)We consider three approximate expressions for the entropy of a single-particle fluid that require as input only the pair-correlation function g(r). By evaluating numerically these entropy estimates, for several model ... -
Molecular-bond hardening and dynamics of molecular stabilization and trapping in intense laser pulses
(American Physical Society, 1993-07-01)We extend our previous study [Chem. Phys. Lett. 197, 413 (1992)] of the molecular stabilization in intense laser fields by considering the dynamical behavior of the H+2 molecules in intense femtosecond short laser pulses ... -
Mechanism of quasi-phase-matching in a dual-gas multijet array
(American Physical Society, 2012-08-31)Quasi-phase-matching in a dual gas (Ar-H2) multijet array has recently been demonstrated to be a promising way to enhance the yield of high-order harmonics (HH). Here, we investigate the HH produced individually from these ... -
Maximum attainable field-free molecular orientation of a thermal ensemble with near–single-cycle THz pulses
(American Physical Society, 2013-01-25)Recently, single-cycle THz pulses have been demonstrated in the laboratory to successfully induce field-free orientation in gas-phase polar molecules at room temperature [Phys. Rev. Lett. 107, 163603 (2011)]. In this paper, ... -
Many-mode Floquet theoretical approach for coherent control of multiphoton dynamics driven by intense frequency-comb laser fields
(American Physical Society, 2008-06-05)We extend the many-mode Floquet theorem (MMFT) for the investigation of multiphoton resonance dynamics driven by intense frequency-comb laser fields. The frequency comb structure generated by a train of short laser pulses ... -
