in scpc-dama satellite networks, the baseband rrc pulse shaping is utilized to reduce the bandwidth and inter symbol interference (isi). but the variation in carrier's envelope, which expands the spectrum and ultimately increases the bandwidth, causes isi and quadrature channel crosstalk (qcc). the goal of this paper is to introduce a method to shape baseband rrc pulses, in order to make a near...

In this work, we analyze the effect of different pulse shaping filters on the performance of the asynchronous DS-CDMA systems employing long spreading sequences over Rayleigh-fading channels. We numerically evaluated and compared the performance of rectangular pulse and square root raised cosine pulses with different rolloff factors for conventional receiver and multiuser detectors. Our work ju...

PURPOSE To compare complications and outcomes in patients undergoing either open radical cystectomy (ORC) or robotic-assisted radical cystectomy (RRC). MATERIALS AND METHODS We retrospectively identified patients that underwent ORC or RRC between 2003- 2013. We statistically compared preliminary oncologic outcomes of patients for each surgical modality. RESULTS 92 (43.2%) and 121 (56.8%) pa...

Root raised cosine roll-off (RRC) filter is one of the most fundamental elements in modern digital communications. This paper proposes a new method to efficiently realize the RRC filter. The method employs cubic Hermite interpolation to obtain a piecewise-polynomial approximation for the impulse response of the RRC filter. Then, the approximated impulse response is efficiently realized by using...

The experimental conditions of the sample delivery inside the reagent-release capillary-based capillary-assembled microchip (RRC-based CAs-CHIP) were optimized and the reagent release procedure in the RRC is discussed. Recently, our group introduced the basic concept of the "drop-and-sip" fluid handling technique (Anal. Chem., 2007, 79, 908). A microliter volume of sample solution is dropped on...

BACKGROUND Radiation related caries (RRC) can cause rapid progression, with a high potential for dental destruction affecting mainly cervical and incisal areas. Unlike the injuries that occur in the conventional caries, incipient RRC present in unusual surfaces have difficult diagnosis and classification stages of cavitation. MATERIAL AND METHODS Evaluate the radiographic patterns of deminera...

Increasing soft error rates for semiconductor devices manufactured in later technologies enforces the use of fault tolerant techniques such as Roll-back Recovery with Checkpointing (RRC). However, RRC introduces time overhead that increases the completion (execution) time. For nonreal-time systems, research have focused on optimizing RRC and shown that it is possible to find the optimal number ...

We previously have isolated an endosomal fraction from rat liver, termed receptor-recycling compartment (RRC), which is highly enriched in recycling receptors and in the transcytotic polymeric Ig receptor (pIgR). We now have analyzed the RRC fraction by immunoisolation and found that no uniquely transcytotic elements were present, because recycling receptors and the pIgR were coisolated on the ...

Cytotoxic-T-lymphocyte (CTL) escape mutations in human immunodeficiency viruses encode amino acid substitutions in positions that disrupt CTL targeting, thereby increasing virus survival and conferring a relative fitness benefit. However, it is now clear that CTL escape mutations can also confer a fitness cost, and there is increasing evidence to suggest that in some cases, e.g., escape from HL...

CCD observations obtained by the OGLE team for 128 RR Lyrae variables in ω Centauri have been analysed. The period-luminosity and period-amplitude plots indicate that, in addition to fundamental (RRab) and first overtone (RRc) pulsators, the ω Centauri RR Lyrae population seems to include second overtone (RRe) and possibly third overtone pulsators. The mean period for the 59 RRab stars is 0.649...
