Transmission power control is essential in WCDMA in order to optimize the bandwidth utilization which is critical when variable data rates are used. One remaining problem is oscillations in the output powers due to round-trip delays in the power control loops together with the power up-down command device. The oscillations are naturally quantified using discrete-time describing functions, which...

OBJECTIVE This study investigates whether performance in a verbal response task (Color-Word Interference Test [CWIT]) and a motor response task (Conners' Continuous Performance Test [CCPT]) discriminates children with Tourette's Syndrome (TS), ADHD, and typically developing children (TDC). METHOD Nineteen children with TS, 79 with ADHD, and 50 with TDC participated (8-17 years). RESULTS Chi...

A novel 12-bit Vernier ring time-to-digital converter (TDC) with 8ps of time resolution for digital-phase-locked-loop applications is presented. The TDC achieves a large detectable range of 32ns. The core of the TDC occupies 0.75 x 0.35 mm in a 0.13um CMOS technology. The total power consumption for the entire TDC chip is only 7.5mW with a 1.5V power supply at a sample rate of 15MSps. Introduct...

Seven uranyl ion complexes have been crystallized under solvo-hydrothermal conditions from 2,5-thiophenedicarboxylic acid (tdcH2) and diverse additional, structure-directing species. [UO2(tdc)(DMF)] (1) is a two-stranded monoperiodic coordination polymer, while [PPh3Me][UO2(tdc)(HCOO)] (2) simple chain with terminal formate coligands. Although it also monoperiodic, [C(NH2)3][H2NMe2]2[(UO2)3(tdc...

BACKGROUND/AIMS Fragmented care in nephrology can cause treatment delays. Nephrologists are qualified to perform vascular access-related procedures because they understand the pathophysiology of renal disease and perform physical examination for vascular access. We compared treatment delays associated with tunneled hemodialysis catheter (TDC) placement between interventional radiologists and ne...

i ACKNOWLEDGEMENTS I would like to thank: Professor Li-Rong Zheng for giving me the opportunity to do my master thesis project in IPACK group at KTH. Dr. Fredrik Jonsson for providing me with the interesting topic and guiding me for the overall research and plan. Dr. Jian Chen for answering all my questions and making the completion of the project possible. in IPACK group for the discussion and...

BACKGROUND Biophysical measures to assess that skin water includes stratum corneum hydration via capacitance (SC), dermal water via tissue dielectric constant (TDC), and transepidermal water loss (TEWL). Since skin differs among anatomical sites and tissue depth we sought to determine the site and depth variability of these measures and their relationships. METHODS Measurements were done at 1...

DEC-205, a transmembrane receptor responsible for cross-presentation of apoptotic cell-derived antigens, is expressed by cortical thymic epithelial cells (TEC) and thymic dendritic cells (TDC) in humans and mice, but its function in T-cell development is still unclear. In this work we have studied for the first time the expression of DEC-205 in the rat thymus by HD83 monoclonal antibody (mAb) a...

In the epithelial follicle stem cells (FSCs) of the Drosophila ovary, Epidermal Growth Factor Receptor (EGFR) signaling promotes self-renewal, whereas Notch signaling promotes differentiation of the prefollicle cell (pFC) daughters. We have identified two proteins, Six4 and Groucho (Gro), that link the activity of these two pathways to regulate the earliest cell fate decision in the FSC lineage...

BACKGROUND The present study aimed to examine the impact of "curricula for undergraduate education in oriental medicine (OM)/complementary and alternative medicine (CAM)" on student awareness of OM. A questionnaire survey was conducted involving the Nagasaki University School of Dentistry (NUSD), a university that implements education in OM as part of its undergraduate curriculum, and Tokyo Den...
