Effectiveness of double umbilical cord blood (dUCB) grafts relative to conventional marrow and mobilized peripheral blood from related and unrelated donors has yet to be established. We studied 536 patients at the Fred Hutchinson Cancer Research Center and University of Minnesota with malignant disease who underwent transplantation with an human leukocyte antigen (HLA)-matched related donor (MR...

GOEL,VIVEK. Semi-blind turbo detection for Multiple-input Multiple-output wireless systems. (Under the direction of Dr. Huaiyu Dai) Multiple-input multiple-output (MIMO) techniques constitute the core of future high speed wireless systems. Blind detection in MIMO wireless systems conserves bandwidth and is better suited for use in multiple user scenarios. Since, most of the modern wireless comm...

Abstract— Incorporating multiuser detection (MUD) at receivers in a Multihop Packet Radio or ad-hoc Network has the potential to drastically improve performance. In this work, possible improvements are investigated and it is suggested that the Channel Coding Theorem be used for accurate modeling of the radio channel. With this model, MUD is shown to be more beneficial to ad-hoc networks employi...

Predator – prey interactions are often highly co-evolved, with selection over time for prey with morphological and behavioral traits that minimize predation risk. Consequently, in many environments prey choose among potential habitats according to their refuge value. It is unclear, however, when presented with new habitats, if prey are able to evaluate the predation risk of these relative to fa...

BACKGROUND Medically unexplained dyspnea (MUD) refers to a condition characterized by a sensation of dyspnea and is typically applied to patients presenting with anxiety and hyperventilation without cardiopulmonary explanations for their dyspnea. The diagnosis is difficult. We investigated whether descriptors of dyspnea and associated symptoms of MUD are differentially diagnostic. METHODS A r...

The arrival of new data services for wireless mobile communications requires an efficient use of the available bandwidth. Interference-limited cellular systems based on codedivision multiple access (CDMA) can benefit from multiuser detection (MUD) and beamforming with antenna array to reduce multiple-access interference. Group-based techniques have been proposed to reduce the complexity of spac...

In addition to their well-known effects on the development of the mushroom body, mud mutants are also female sterile. Here we show that, although the early steps of ovary development are grossly normal, a defect becomes apparent in meiosis II when the two component spindles fail to cohere and align properly. The products of meiosis are consequently mispositioned within the egg and, with or with...

This work proposed a new multiuser detector for DS/CDMA systems constituted by the polynomial MMSE detector followed by a local search algorithm 1-adapt LS (one-adaptive local search), namely the Hybrid 1adapt-LS-MuD. In order to reduce computational complexity inherent to recurrent computation of the cross-correlation matrix inverse in DS/CDMA multiuser detection (MuD), this work introduces fo...

This study reports an adaptation of a parametric echosounder system using 15 kHz as secondary frequency to investigate the angular response of sub-bottom backscatter strength of layered mud, providing a new method for enhanced acoustic detection of buried targets. Adaptions to achieve both vertical (0°) and non-vertical inclination (1– 15°, 30°, 45° and 60°) comprise mechanical tilting of the a...

Flume experiments simulating a 12.5 hour tidal cycle were performed to test the hypothesis that flaser and wavy bedding can be produced in shallow subtidal areas by tidal activity. The effects of clay composition, sand size, total amount of sediment deposited, compaction time, and peak current velocity were investigated. It was found that the resistance of a recently-deposited mud bed to subseq...
