In this paper, we study some of the main properties of the double base number system (DBNS), using bases 2 and 5. A simple geometric interpretation provides the implementation of the arithmetic operations and the addition and multiplication rules of this number systems have been introduced. It can also be shown that the double base number system is used in(More)
CONTEXT Chlamydial and gonococcal infections are important causes of pelvic inflammatory disease, ectopic pregnancy, and infertility. Although screening for Chlamydia trachomatis is widely recommended among young adult women, little information is available regarding the prevalence of chlamydial and gonococcal infections in the general young adult(More)
BACKGROUND North Carolina has added nucleic acid amplification testing for the human immunodeficiency virus (HIV) to standard HIV antibody tests to detect persons with acute HIV infection who are viremic but antibody-negative. METHODS To determine the effect of nucleic acid amplification testing on the yield and accuracy of HIV detection in public health(More)
BACKGROUND HIV transmission risk is higher during acute and early HIV infection than it is during chronic infection, but the contribution of early infection to the spread of HIV is controversial. We estimated the contribution of early infection to HIV incidence in Lilongwe, Malawi, and predict the future effect of hypothetical prevention interventions(More)
BACKGROUND Raised HIV viral load in blood has been associated with accelerated disease progression and increased transmission of infection. To assess the effect of Plasmodium falciparum malaria on concentrations of HIV in blood, we did a prospective cohort study in Malawi. METHODS We recruited 367 HIV-1-infected adults. Among 334 people aparasitaemic at(More)
BACKGROUND To assess the effects of human immunodeficiency virus (HIV) infection on susceptibility to malaria, we compared the incidence rates of malaria by HIV type 1 (HIV-1) serostatus, baseline blood HIV-1 RNA concentration, and baseline CD4 cell count, over the course of a malaria season. METHODS We followed a cohort of 349 adults in Malawi. For the(More)
ÐIn this paper, we propose new algorithms for multiple modular exponentiation operations. The major aim of these algorithms is to speed up the performance of some cryptographic protocols based on multiexponentiation. Our new algorithms are based on binary-like complex arithmetic, introduced by Pekmestzi and generalized in this paper. Index TermsÐModular(More)
BACKGROUND Mood and anxiety disorders, particularly depression, and substance abuse (SA) commonly co-occur with HIV infection. Appropriate policy and program planning require accurate prevalence estimates. Yet most estimates are based on screening instruments, which are likely to overstate true prevalence.
