We modified a p24 antigen enzyme-linked immunosorbent assay as a method for diagnosis and monitoring of human immunodeficiency virus type 1 (HIV-1) subtype E infection. This modified assay is based on the use of preheated immune complex dissociation combined with a booster step using a regular Vironostika HIV-1 p24 antigen assay (bioMerieux) to decrease the lower limit of p24 antigen detection ...

The Arnoldi process is a well known technique for approximating a few eigenvalues and corresponding eigenvectors of a general square matrix. Numerical difficulties such as loss of orthogonality and assessment of the numerical quality of the approximations as well as a potential for unbounded growth in storage have limited the applicability of the method. These issues are addressed by fixing the...

We present a methodology that detects spatial patterns of 3-dimensional point processes that include a mass within the study region. Spatial patterns such as clustering, randomness, or repulsion are considered in respect to the mass surface. Our method closely resembles Ripley’s K Function but is modified to discern the pattern about the mass surface. We walk though the definition and derivatio...

This research resulting the method to reduce phasor measurement unit (PMU) amount and optimization of PMU replacement using a combination Integer linear k-means. The first step modeling is lot PMUs that are optimized at Bendul Merisi network integer k-means clustering for achieving an optimum solution be installed. second estimating uninstalled bus's power voltage. modified adaptive neuro-fuzzy...

with the increasing number of keratorefractive surgical procedures in the past years, an increasing number of cataract operations in eyes with previous keratorefractive surgery is anticipated. although cataract extraction seems to be feasible without major technical obstacles, intraocular lens (iol) power calculation remains problematic. insertion of measured k-readings after myopic photorefrac...

Present fully polarimetric synthetic aperture radar (SAR) systems often update calibration techniques to further enhance the accuracy to the polarimetric data. In this paper, we propose a modified method to estimate the value of crosstalk based on the corrected observed value. Since Ainsworth calibration algorithm firstly set the value of k to be one. And the value of k relates to the copolariz...
