High data rates, low-power consumption, and low complexity will be the most important parameters in the design of the nextgeneration mobile terminals. In this paper we are introducing a new paradigm in the design of direct sequence spread spectrum receiver by combining analog and digital signal processing. Themain difference with respect to the conventional all-digital receiver design approach ...

We experimentally demonstrate a spatially non-blocking five-port optical router, which is based on microring resonators tuned through the thermo-optic effect. The characteristics of the microring-resonator-based switching element are investigated to achieve balanced performances in its two output ports. The optical router is fabricated on the SOI platform using standard CMOS processing. The eff...

Development of a new regular topology for Network on Chip (NoC) is a challenging task, as the proposed design should meet the application specific targets of latency, throughput, area, and energy as well. A suitable routing over newly proposed topology must handle congestion and provide deadlock free transmission. This paper discusses design, implementation of five port regular NoC structure (e...

BACKGROUND single-port laparoscopic surgery has gained popularity over the last decade. This technique is used for several surgical procedures. This paper documents a new and cheaper access method known as "surgical glove port" or "homemade single-port", and describes our initial experience with 25 cases. METHOD Eleven cholecystectomies, eight totally extraperitoneal inguinal hernia repairs, ...

Wilms’ tumour is the most common among renal tumours in paediatric population. In Africa, data on pediatric are rare. This study aims to highlight challenges and peculiarities management of a resource-poor setting. Materials Methods five-year retrospective conducted at University Port Harcourt Teaching Hospital. Ethical approval for was sought gotten from hospital’s ethical committee. The infor...

PURPOSE To explore the value of radiotherapy in C-SCLC patients, especially in those receiving a radical resection. RESULTS The differences of survivals between the postoperative radiotherapy (PORT) and non-PORT groups were not statistically significant. But analyzing the benefits in subgroups, PORT significantly improved OS (p = 0.015), DFS (p = 0.026), LRFS (p = 0.008) and DMFS (p = 0.030) ...

BJECTIVES To report an initial clinical urologic experience with a new laparoscopic access port (R-Port) and the advent of the single-port access (SPA) procedure and one-port umbilical surgery (OPUS). ETHODS Five patients underwent therapeutic laparoscopic interventions (two simple nephrectomies for end-stage kidney disease consequent to stone disease, one orchidopexy, one orchidectomy, and one...

The five-port reflectometer has been recently applied to demodulators and radars, offering an alternative to classic In-Phase/In-Quadrature (I/Q) discriminators. In these applications, calibration of the reflectometer is an important task. Most of the methods developed are suitable for the instrumentation and measurement field and present a high degree of complexity. We propose in this paper a ...
