Bacterial infections are frequent, life-threatening complications in cirrhotic patients. This study investigated in vivo neutrophil migration and phagocytic activity in cirrhotic patients with advanced liver disease, in liver transplant recipients, and in healthy volunteers, by use of the skin window technique. Complement receptor type III (CR3) expression(More)
Traditionally, noise power estimation has been done by either sending training signals or by not sending signal at all. In this paper, two approaches are presented that do not use training signals. One uses the expectation-maximization (EM) algorithm and approaches the maximum likelihood (ML) estimate using the received data, if given a good initial(More)
In current discrete multitone (DMT) wireline modems, crosstalk interference has been the major limitation in achieving high data rates. The introduction of a crosstalker can cause such a large disturbance that the mo-dem is not able to adapt sufficiently fast and may cause the modem to reinitialize. This paper presents a maximum a posteriori (MAP) algorithm(More)
Accurate detection of liver lesions is of great importance in hepatic surgery planning. Recent studies have shown that the detection rate of liver lesions is significantly higher in gadoxetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-enhanced MRI) than in contrast-enhanced portal-phase computed tomography (CT); however, the latter remains(More)
The primary objective of the Next Generation Networks, which are based on Multiuser Orthogonal frequency division multiplexing (MU-OFDM) is to increase the network efficiency by maximizing the total throughput of the system and minimizing the overall transmit power for a give quality of service (QOS). MU-OFDM is one of the promising techniques for achieving(More)
This paper reviews key features of the 10 GBASE-T standard for full duplex 10 Gb/s transmission over structured copper cabling in the LAN environment. Tradeoffs in implementing 10 GBASE-T transceivers are discussed. We then present the first implementation of 10 GBASE-T in digital CMOS technology (0.13 mum). This transceiver also supports lower speeds for(More)
A study of space-time block coding in analytical form-multiple input and multiple output (STBC-MIMO) system was done in various cases. Initially, a basic Alamouti scheme for encoding was illustrated. Then, the performance of proposed STBC-MIMO was studied under varying a number of transmitting antennas, varying number of receiving antennas, varying(More)
