The Singular Value Decomposition (SVD) of a matrix is a linear algebra tool that has been successfully applied to a wide variety of domains. The present paper is concerned with the problem of estimating the Jacobian of the SVD components of a matrix with respect to the matrix itself. An exact analytic technique is developed that facilitates the estimation of the Jacobian using calculations base...

Summary A multinational survey was conducted to evaluate the gaps between patients and physicians understanding of osteoporosis. The International Osteoporosis Foundation recommends the creation of community-wide patient support programmes to increase prevention and treatment awareness of osteoporosis. Introduction Osteoporosis is often undiagnosed and untreated, leaving millions of people at r...

TOPIC: Cardiovascular Disease TYPE: Medical Student/Resident Case Reports INTRODUCTION: Cardiac involvement in myasthenia gravis (MG) is extremely rare. Antibody (Ab) induced myocarditis MG patients can be difficult to distinguish from myasthenic crisis (MC). Both conditions lead dyspnea and orthopnea, especially with bulbar involvement. If clinicians are unaware, troponin (Tn) elevation electr...

UNLABELLED The prevalence and regulation of p38 mitogen activated protein kinase (MAPK) expression in human lymphomas have not been extensively studied. In order to elucidate the role of p38 MAPK in lymphomagenesis, we examined the expression of native and phosphorylated p38 (p-p38) MAPK in cell lines derived from human hematopoietic neoplasms including B cell lymphoma-derived cell lines using ...

BACKGROUND The emergence and spread of high levels of HIV-1 drug resistance in resource-limited settings where combination antiretroviral treatment has been scaled up could compromise the effectiveness of national HIV treatment programmes. We aimed to estimate changes in the prevalence of HIV-1 drug resistance in treatment-naive individuals with HIV since initiation of rollout in resource-limit...

We explain work on the arithmetic of Gamma and Zeta values for function fields. We will explore analogs of the gamma and zeta functions, their properties, functional equations, interpolations, their special values, their connections with periods of Drinfeld modules and t-motives, algebraic relations they satisfy and various methods showing that there are no more relations between them. We also ...

This study assesses the measurement properties of RyV’s Scales of Psychological Well-Being (RPWB)—a widely used instrument designed to measure six dimensions of psychological well-being. Analyses of self-administered RPWB data from three major surveys—Midlife in the United States (MIDUS), National Survey of Families and Households II, and the Wisconsin Longitudinal Study (WLS)—yielded very high...

Sir, Clinical photography enhances medical records and is essential for the daily practice of surgeons. Important uses of photographs include patient counselling, audit, publications, education, medico-legal work and for planning treatment without repeatedly redressing the wound. The value of such photographs are realised when they are needed, no doubt we have all been painfully aware of this w...

The logistical requirements placed on industrial manufacturing companies are steadily increasing. In order to meet those requirements, a consistent and efficient concept is necessary for production control. Set up properly, production control offers considerable potential with respect to achieving the logistical targets. As experience with the many production control methods already in existenc...

A large proportion of In this paper we present the entire genomic segenes with a tissue-restricted expression pattern also quence as well as the cDNA sequence of two new hucontain CpG islands. An interesting feature of CpG man genes encoding the g subunit of the NAD-depenislands is that at least some are capable of initiating dent isocitrate dehydrogenase (H-IDH...
