CONTEXT The gained expertise in the surgical technique of partial nephrectomy (PN) with excellent oncologic outcome and reduced morbidity has contributed to more frequent use of PN in many centres of reference, and the recent evidence favouring PN over radical nephrectomy (RN) in the prevention of chronic kidney disease and possibly linking it to a better overall survival (OS) will constitute a...
The LFSR operations are performed in implementing the different mobile-device protocols and encryption standards during transmission and reception. These operations are performed at the PN coding stages in CDMA, Gold code generation stage in WCDMA and several operation stages in the mobile transmitter and receiver protocols in Software Defined Radios (SDRs). A kernel can instantiate several pro...
We propose a multiple dwell serial search (MDSS) code acquisition for optical code-division multiple-access (O-CDMA) systems and theoretically analyze its performance. The search/lock strategy (SLS) is used as verification scheme for the multiple dwell detector. The operation of SLS is modeled by finite Markov chain to analyze the performance of the proposed system. Effect of system parameters,...
A basic step in the asynchronous DS/CDMA reception consists in the effective acquisition of the initial pseudonoise (PN) synchronism. This is especially true in the case of multi-user DS/CDMA systems, dominated by multi-user interference (MUI), as it often happens in multimedia satellite networks, generally characterised by asynchronous transmission. In this work, an adaptive PN acquisition sch...
Compared to enteral or hypocaloric oral nutrition, the use of PN (parenteral nutrition) is not associated with increased mortality, overall frequency of complications, or longer length of hospital stay (LOS). The risk of PN complications (e.g. refeeding-syndrome, hyperglycaemia, bone demineralisation, catheter infections) can be minimised by carefully monitoring patients and the use of nutritio...
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
INTRODUCTION The EPaNIC randomized controlled multicentre trial showed that postponing initiation of parenteral nutrition (PN) in ICU-patients to beyond the first week (Late-PN) enhanced recovery, as compared with Early-PN. This was mediated by fewer infections, accelerated recovery from organ failure and reduced duration of hospitalization. Now, the trial's preplanned cost analysis (N = 4640) ...
Motivated by the discovery that the eighth root of the theta series of the E8 lattice and the 24th root of the theta series of the Leech lattice both have integer coefficients, we investigate the question of when an arbitrary element f ∈ R (where R = 1 + xZ x ) can be written as f = gn for g ∈ R, n 2. Let Pn := {gn | g ∈R} and let μn := n∏p |n p. We show among other things that (i) for f ∈R, f ...
Nowadays, software evolution is a very hot topic. It is particularly complex when it regards critical and nonstopping systems. Usually, these situations are tackled by hard-coding all the foreseeable evolutions in the application design and code. Neglecting the obvious difficulties in pursuing this approach, we also get the application code and design polluted with details that do not regard th...
