We study the local convergence of a predictor-corrector algorithm for semideenite programming problems based on the Monteiro-Zhang uniied direction whose polynomial convergence was recently established by Monteiro. We prove that the suucient condition for superlinear convergence of Potra and Sheng applies to this algorithm and is independent of the scaling(More)
BACKGROUND The objective of the study was to expand the investigation of the match/mismatch mnemonic impairment in the semantic domain in sober alcoholics. METHODS Event-related potentials (ERPs) were recorded from 28 healthy adults and 36 sober alcoholics in a category (either animals or fruits/vegetables) match/nonmatch S1-S2 paradigm. RESULTS There(More)
Spike length (SL), spikelet number (SPN) per spike, kernel number per spike (KNPS), and thousand-kernel weight (TKW) have strong genetic associations with kernel weight per spike (KWPS) in wheat. To investigate their genetic relationships at the individual quantitative trait locus (QTL) level, both unconditional and conditional QTL mapping for KWPS with(More)
Iron deficiency anemia is an extra-stomach disease experienced in H. pylori carriers. Individuals with type A blood are more prone to suffering from H. pylori infection than other individuals. To clarify the molecular mechanisms underlying H. pylori-associated anemia, we collected erythrocytes from A, B, O, and AB blood donors and analyzed morphology, the(More)
BACKGROUND There is controversy in the literature regarding the relationship between event-related-potential (ERP) abnormalities in abstinent alcoholics and stimulus-processing modality (i.e., visual versus auditory). The first purpose of this study was to address questions about whether ERP abnormalities observed in alcoholics are modality specific. The(More)
PURPOSE To examine the topographic relationship of P3(00) between the visual and auditory modalities, especially to examine whether there are any modality-specific hemispheric differences of P3 in normal adults. METHODS The P3s were recorded from the same 41 normal right-handed males between the ages of 20 and 33 in both a typical auditory oddball task(More)

A predictor-corrector method for solving the P ()-matrix linear complementarity problems from infeasible starting points is analyzed. Two matrix factorizations and two backsolves are performed at each iteration. The algorithm terminates in O ? (+ 1) 2 nL steps either by nding a solution or by determining that the problem is not solvable. The computational(More)
We consider an infeasible-interior-point algorithm, endowed with a nite termination scheme, applied to random linear programs generated according to a model of Todd. Such problems have degenerate optimal solutions, and possess no feasible starting point. We use no information regarding an optimal solution in the initialization of the algorithm. Our main(More)
Existing Parkinson's Disease (PD) diagnosis relies heavily on doctors' observations combined with neurological exams. Such a technique is often inconvenient, infrequent, and subjective , which leads to a high misdiagnosis rate. As several cardinal symptoms of PD require long term observations, a technology platform which allows potential PD patients to(More)
