Wave Propagation In Metamaterial Using Multiscale Resonators By Creating Local Anisotropy, Raiz U. Ahmed, Sourav Banerjee

Faculty Publications

Directional guiding, passing or stopping of elastic waves through engineered materials have many applications to the engineering fields. Recently, such engineered composite materials received great attention by the broader research community. In elastic waves, the longitudinal and transverse motion of material particles are coupled, which exhibits richer physics and demands greater attention than electromagnetic waves and acoustic waves in fluids. Waves in periodic media exhibit the property of Bragg scattering and create frequency band gaps in which the energy propagation is prohibited. However, in addition to the Bragg scattering, it has been found that local resonance of artificially designed resonators …

Simulation Studying Effects Of Multiple Primary Aberrations On Donut-Shaped Gaussian Beam, Chen Zhang, K. Wang, J. Bai, Y. Liu, Guiren Wang

Faculty Publications

In this paper, we demonstrate the variation of donut-shaped depletion pattern which influenced by multiple primary aberrations. The simulation is base on a common stimulation emission of depletion (STED) system composed by Gaussian laser and vortex phase plate. The simulation results are helpful guidelines for analyzing the aberration of depletion patterns in real situations.

An Acid Catalyzed Reversible Ring-Opening/Ring-Closure Reaction Involving A Cyano-Rhodamine Spirolactam, H. Li, H. Guan, X. Duan, J. Hu, Guiren Wang, Qian Wang

Faculty Publications

Cyanamide was introduced into the rhodamine spirolactam framework to produce a colorless and non-fluorescent compound RBCN. It shows a reversible ring-opening/ring-closure process in response to the solution pH, which exhibits an “ON/OFF” switching in its fluorescence. Different from other rhodamine-type dyes, the ring-open form of RBCN is stable in protic solvents under neutral, near neutral and basic conditions, showing a pink color and very strong fluorescence. We also demonstrated the potential of RBCN in live cell imaging.

Understanding the influence of sex differences on predictors of cardiac mortality rates in chronic heart failure might enable us to lengthen lifetimes and to improve lives. This study describes the influence of sex on cardiovascular mortality rates among chronic heart failure patients.

From January 2003 through December 2009, we evaluated 637 consecutive patients (409 men and 228 women) with chronic heart failure, who ranged in age from 18 through 94 years (mean age, 64 ± 13 yr) and ranged in New York Heart Association (NYHA) functional class from II through IV. The mean follow-up period was 38 ± 15 months, …

Coronary Artery Diameter Related To Calcium Scores And Coronary Risk Factors As Measured With Multidetector Computed Tomography: A Substudy Of The Accuracy Trial, Yasmin S Hamirani, Khurram Nasir, Emil Avanes, Jigar Kadakia, Matthew J Budoff

The Texas Heart Institute Journal

Arterial remodeling, an early change of atherosclerosis, can cause dilated arterial diameter. We measured coronary artery diameter with use of noncontrast 64-slice multidetector computed tomography (MDCT), and studied its association with coronary artery calcium levels and traditional coronary risk factors.

We included 140 patients from the ACCURACY trial whose noncontrast MDCT images showed measurable coronary arteries. Using 3 measurements of left main coronary artery (LMCA) and right coronary artery (RCA) diameters within 3 mm of the ostium, we associated the results with traditional coronary risk factors and calcium scores.

The prevalence of LMCA and RCA calcium was 22% and 51%, …
