The recent discovery of a hyper-metal-poor (HMP) star, with a metallicity Fe/H smaller than 1/100,000 of the solar ratio, together with one earlier HMP star, has raised a challenging question whether these HMP stars are the actual first-generation, low-mass stars of the universe. We argue that these HMP stars are second-generation stars formed from gases that were chemically enriched by the fir...

Given a collection of points in a multi-dimensional space, we consider the problem of nding the set of all possible Maximal Hyper-Rectangle (MHR), deened to be hyper-rectangles that are empty and have at least a point bounding each of its surfaces. It is easy to see that there are enormous number of such MHRs in a given instance, and most of the time, applications require only to nd the \larges...

Focused attention can be compromised by the neurodegenerative processes associated with both healthy aging and Parkinson's disease (PD). Deficits in ignoring distractors with reflexive or overlearned response links have been attributed to impaired inhibition. The current research assessed whether similar deficits occur for distractors with recently learned arbitrary response associations, for w...

We studied a patient who had a typical seronegative rheumatoid arthritis (RA) and an immunodeficiency with hyper-IgM (HIM syndrome). CD40L was normally expressed by activated T cells, but CD40-mediated signal transduction was defective in B cells, preventing heavy chain switching (CD40L+ type of the HIM syndrome). These data suggest that a typical RA can develop in at least some patients with d...

The Hyper-Space Diagonal Counting (HSDC) method was previously proposed for generating representations of n-dimensional data in 2or 3-dimensions. Since its inception, the HSDC has been used to visualize the n-dimensional performance space in an intuitive fashion for Multiobjective Optimization Applications, through the incorporation of the HSDC into the Hyperspace Pareto Frontier (HPF) visualiz...

Selective immunoglobulin M deficiency(sIgMD) is a rare form of dysgammaglobulinaemia characterized by an isolated low level of serum immunoglobulin M (IgM). It was an incidence of less than 0.03% in the general population and 1% in hospitalized patients. sIgMD may occur as a primary or secondary condition. sIgMD is much more common than primary .Hemophagocytic lymphohistiocytosis (HLH) is also ...

Aims: To assess potential changes of pharmacological activities a novel normal immunoglobulin for intravenous administration from pooled plasma (IVIG). Methods: We assessed the impact SARS-CoV-2 pandemic on level and activity pathogen-specific antibodies in IVIG batches produced before during pandemic. Antibody levels were determined by immunoassays. The functional was vitro neutralization. Res...
