FLASH: ultra-fast protocol to identify RNA-protein interactions in cells
Determination of the in vivo binding sites of RNA-binding proteins (RBPs) is paramount to understanding their function and how they affect different aspects of gene regulation. With hundreds of RNA-binding proteins identified in human cells, a flexible, high-resolution, high-throughput, highly multiplexible and radioactivity-free method to determine their binding sites has not been described to date. Here we report FLASH (Fast Ligation of RNA after some sort of Affinity Purification for High-throughput Sequencing), which uses a special adapter design and an optimized protocol to determine protein-RNA interactions in living cells. The entire FLASH protocol, starting from cells on plates to a sequencing library, takes 1.5 days. We demonstrate the flexibility, speed and versatility of FLASH by using it to determine RNA targets of both tagged and endogenously expressed proteins under diverse conditions in vivo
Hispanic Subgroups, Acculturation, and Substance Abuse Treatment Outcomes
This study explored Hispanic subgroup differences in substance use treatment outcomes, and the relationship of acculturation characteristics to these outcomes. Data were from a multisite randomized clinical trial of motivational enhancement therapy versus treatment as usual in a sample of Spanish-speaking substance abusers. Participants were Cuban American (n = 34), Mexican American (n = 209), Puerto Rican (n = 78), and other Hispanic American (n = 54). Results suggested that Cuban Americans and individuals with more connection to Hispanic culture had lower treatment retention. Hispanics born in the U.S and those who spoke English at home had a lower percentage of days abstinent during weeks 5–16, although Puerto Ricans born in the U.S. and Cuban Americans living more years in the U.S. had a higher percentage of days abstinent in weeks 1–4 and 5–16, respectively. Results may inform future hypothesis-driven studies in larger Hispanic treatment seeking samples of the relationship between acculturation and treatment outcome
Charge-noise-free Lateral Quantum Dot Devices with Undoped Si/SiGe Wafer
We develop quantum dots in a single layered MOS structure using an undoped
Si/SiGe wafer. By applying a positive bias on the surface gates, electrons are
accumulated in the Si channel. Clear Coulomb diamond and double dot charge
stability diagrams are measured. The temporal fluctuation of the current is
traced, to which we apply the Fourier transform analysis. The power spectrum of
the noise signal is inversely proportional to the frequency, and is different
from the inversely quadratic behavior known for quantum dots made in doped
wafers. Our results indicate that the source of charge noise for the doped
wafers is related to the 2DEG dopant.Comment: Proceedings of the 12th Asia Pacific Physics Conferenc

Financial Performance Comparison of Islamic and conventional banks in the United Arab Emirates (UAE)
This paper examines the financial performance of Islamic and commercial banks in the United Arab Emirates (UAE). The paper gives an empirical insights and comparisons between the performance of Islamic and conventional banking sectors. The sample of the study consists of 5 fully-fledged Islamic banks and 14 conventional banks working in the UAE under the period 2011-2014. The study uses descriptive analysis, correlation, independent sample t test and multiple regression analysis to assess the performance and to compare between both types of banks. The Return on Assets (ROA) is used as proxy for profitability for both types of banks while bank size (log A), liquidity, capital adequacy, financial risk and operating efficiency as proxies for financial performance for both types of banks. The results showed that there is no significant difference between Islamic banks and conventional banks in terms of profitability (ROA) while there is a significant difference between Islamic and conventional banks in terms of liquidity, operation efficiency, capital adequacy, and financial risk. Further, the results indicated that the Islamic banks have higher operating efficiency, bank size and more liquidity than their counterparts of UAE. However, conventional banks are found to have better capital adequacy ratio than Islamic banks. In terms of financial risk, Islamic banks are found to have higher five times than conventional banks which may reflect challenges in the area of risk management in Islamic banks.
