Businesses often need an accurate profile of their customers in order to better serve them, improve products and make advertising more effective. Unfortunately, customers do not always completely fill out the survey forms, especially those product registration cards. The forms often have multiple choice questions and customers may leave some questions blank. This paper presents a maximum likeli...

Previous work on Hong Kong Cantonese has reported evidence of an incomplete neutralization between the labialized velar /kʷ/ and plain /k/, where both may be produced as a [k] before /ɔ/, although non-neutralized forms are also to some extent for speakers (Bauer 1982, Zee 1999, To, Mcleod & Cheung 2015). The present study examines this phenomenon acoustically, evaluates what properties labi...

Electrophoresis on polyacrylamide gels was found to be a powerful technique for separating the mature from the precursor forms of bacterial ribosomal nucleic acid (rRNA). The separation of the 16S rRNA from its precursor was, for all practical purposes, complete; that of the 23S rRNA from its precursor was detectable but incomplete. When mature and precursor rRNA preparations were heated to ran...

The objective of this study was to evaluate the behavioral risks that are associated with human herpesvirus 8 (HHV-8) infection in a cohort of young homosexual men. Seventy-nine subjects (ages 22-33 years) who completed a questionnaire about their sexual and drug use behavior over the preceding year were recruited from the San Francisco Young Men's Health Study. Plasma samples were tested for a...

This paper presents a suucient condition on sparsity patterns for the existence of the incomplete Cholesky factorization. Given the sparsity pattern P(A) of a matrix A, and a target sparsity pattern P satisfying the condition, incomplete Cholesky factorization successfully completes for all symmetric positive deenite matrices with the same pattern P(A). This condition is also necessary in the s...

INTENDED USE MBL Bion REAGENTS FOR IFA (Indirect Fluorescent Antibody) TESTS may be used in assays for the qualitative and/or semi-quantitative determination of specific IgG or IgM antibodies in human serum. The MBL Bion REAGENTS FOR IFA TESTS are intended for use as an aid in diagnosis of certain autoimmune diseases or for primary or active infection and/or as a determination of immunological ...

Annual incidence rates of extrapulmonary tuberculosis have been increasing over the last few years in the Kingdom of Saudi Arabia. True rates may even be higher due to incomplete reporting. Diagnosis of this condition requires high clinical suspicion, special diagnostic procedures, special staining, and culture media for acid fast bacilli. Delayed diagnosis results in increasing morbidity, mort...
