AbstractThe goal of the paper is to study the loss of regularity for special p-evolution type models with bounded coefficients in the principal part. The obtained loss of regularity is related in an optimal way to some unboundedness conditions for the derivatives of coe...

Abstract We consider two infinitesimal generators A , B of strongly continuous groups in a general Banach space X , such that either the commutator between A and B commutes both with e tA and with e tB , or the commutator is a multiple of A . We prove that under suitabl...

Abstract Subtilase (SubAB) is a cytotoxin elaborated by some Shiga Toxin (Stx)-producing Escherichia coli (STEC) strains usually lacking the locus of enterocyte effacement (LEE). Two variants of SubAB coding genes have been described: subAB 1 , located on the plasmid of...

Abstract In this paper, we present an integrated system to detect Ochratoxin A (OTA) in feed, food and beverage. Its characteristics of portability, simplicity, sensitivity, low cost and user friendly, make the system suitable to be used by unskilled personnel. The syst...

Abstract It is shown that • there does not exist a (bounded) metric space X with more than one element which is isometric to the metric space CL(X) of nonempty and closed subsets of X endowed with the Hausdorff metric, and • there does not exist a (bounded) metric space...

Signaling is regulated by endocytosis at multiple levels along endocytic routes. Endocytic control of signaling starts already at the plasma membrane, where cells employ different mechanisms to finely tune the type and strength of signals emanating from the cell surface...

Abstract Many researchers and teachers agree that the inclusion of Science, Technology, Engineering, and Math in early education provides a strong motivation and a great improvement in learning speed. Most curricula in primary schools include a number of concepts that c...

To the Editor: We read with interest the commentary by Ulrich Spengler (1) where he evaluated a recent manuscript by Lang et al. (2) on the role of platelet-derived serotonin in the pathogenesis of viral hepatitis. We were somewhat surprised to see that work constitutin...

AbstractCardiomyopathy is a frequent cause of morbidity and mortality in patients carrying the A3243G transition in the mitochondrial DNA (mtDNA) tRNALeu(UUR) gene, the most common heteroplasmic single mtDNA defect. We used phosphorus magnetic resonance spectroscopy (31...
