Efficient VLSI Implementation of Soft-input Soft-output Fixed-complexity Sphere Decoder

Fixed-complexity sphere decoder (FSD) is one of the most promising techniques for the implementation of multipleinput multiple-output (MIMO) detection, with relevant advantages in terms of constant throughput and high flexibility of parallel architecture. The reported works on FSD are mainly based on software level simulations and a few details have been provided on hardware implementation. The authors present the study based on a four-nodes-per-cycle parallel FSD architecture with several examples of VLSI implementation in 4 × 4 systems with both 16-quadrature amplitude modulation (QAM) and 64-QAM modulation and both real and complex signal models. The implementation aspects and details of the architecture are analysed in order to provide a variety of performance-complexity trade-offs. The authors also provide a parallel implementation of loglikelihood- ratio (LLR) generator with optimised algorithm to enhance the proposed FSD architecture to be a soft-input softoutput (SISO) MIMO detector. To the authors best knowledge, this is the first complete VLSI implementation of an FSD based SISO MIMO detector. The implementation results show that the proposed SISO FSD architecture is highly efficient and flexible, making it very suitable for real application

Evaluation of Musa spp. for resistance to moko disease (Ralstonia solanacearum, race 2).

The objetive this paper was to evaluate the reaction of 31 diploid (AA) genotypes to the inoculation with R. solanacearum, race 2, aiming at selecting resistant ones to be used as male parents in the banana breeding programme under conduction at the Embrapa Cassava and Fruit Crops (EMBRAPA-CNPMF), in the Manaus-AM (Brazil)

Doenças das cucurbitáceas no Estado do Amazonas.

Nos sistemas de produção da agricultura familiar, no Estado do Amazonas, as cucurbitáceas ocupam expressivas áreas, pois são espécies muito populares, de fácil colocação no mercado. As condições climáticas prevalecentes no Estado, caracterizadas por médias elevadas da precipitação anual, da temperatura e da umidade relativa do ar, não são fisiologicamente restritivas às exigências desse grupo de espécies tropicais. Entretanto, formam ambiente ideal para ocorrência e disseminação de patógenos. Nessas condições, os cultivos apresentam, frequentemente, sérios problemas fitossanitários, que afetam a qualidade dos produtos, e as perdas podem superam 70% da produção.bitstream/CPAA-2009-09/7055/1/circ_tec9.pd

X-ray standing wave and reflectometric characterization of multilayer structures

Microstructural characterization of synthetic periodic multilayers by x-ray standing waves have been presented. It has been shown that the analysis of multilayers by combined x-ray reflectometry (XRR) and x-ray standing wave (XSW) techniques can overcome the deficiencies of the individual techniques in microstructural analysis. While interface roughnesses are more accurately determined by the XRR technique, layer composition is more accurately determined by the XSW technique where an element is directly identified by its characteristic emission. These aspects have been explained with an example of a 20 period Pt/C multilayer. The composition of the C-layers due to Pt dissolution in the C-layers, Pt$_{x}$C$_{1-x}$, has been determined by the XSW technique. In the XSW analysis when the whole amount of Pt present in the C-layers is assumed to be within the broadened interface, it l eads to larger interface roughness values, inconsistent with those determined by the XRR technique. Constraining the interface roughness values to those determined by the XRR technique, requires an additional amount of dissolved Pt in the C-layers to expl ain the Pt fluorescence yield excited by the standing wave field. This analysis provides the average composition Pt$_{x}$C$_{1-x}$ of the C-layers .Comment: 12 pages RevTex, 10 eps figures embedde

Topical Analgesia with Lidocaine Plus Diclofenac Decreases Pain in Benign Anorectal Surgery: Randomized, Double-blind, and Controlled Clinical Trial

Objective: The aim of this study is to evaluate the efficacy and safety of a topical formulation containing lidocaine plus diclofenac (CLIFE1) compared to CLIFE2 (lidocaine), to decrease pain in benign anorectal surgery (BARS) to date not evaluated. Background: More than 50% of patients undergoing BARS, especially hemorrhoidectomy, suffer from moderate and severe postoperative pain. This remains an unresolved problem that could be addressed with the new CLIFE1 topical treatment. Methods: A multicenter, randomized double-blind, active-controlled parallel-group superiority trial, was conducted in two Spanish hospitals. Patients undergoing BARS (hemorrhoids, anal fistula and anal fissure) were randomized at the end of surgery at a 1:1 ratio to receive first dose either CLIFE1 (n=60) or CLIFE2 (n=60) anorectal topical treatment, and after every 12 hours for the first three postoperative days and once a day from the fourth to sixth. The primary outcome was average of pain decrease after topical treatment, measured with visual analogue scale (VAS) by the patients themselves, the evening in the surgery day and four times daily for the first three postoperative days. Results: The results of 120 patients included out of 150 selected undergoing BARS show a decrease in pain after CLIFE1 topical treatment (7.47±13.2) greater than with CLIFE2 (4.38±6.75), difference -3.21 (95% CI) -5.75; -0.676; p=0.008), decreasing significantly postoperative pain (≥ 9 mm, VAS) in 35% of patients undergoing benign anorectal surgery, compared to 18.33 % treated with lidocaine. Conclusions: The CLIFE1 topical treatment shows better analgesic efficacy than CLIFE2 in BARS
