This paper studies the possible Hodge groups of simple polarizable Q-Hodge structures with Hodge numbers (n, 0, . . . , 0, n). In particular, it generalizes earlier work of Ribet and MoonenZarhin to completely determine the possible Hodge groups of such Hodge structures when n is equal to 1, 4, or a prime p. In addition, the paper determines possible Hodge groups, under certain conditions on th...

The theme of this article is the connection between the pro-unipotent fundamental group π1(X; o) of a pointed algebraic curve X, algebraic cycles, and special values of Lfunctions. The extension of mixed Hodge structures arising in the second stage in the lower central series of π1(X; o) gives rise to a supply of complex points on the Jacobian Jac(X) of X, indexed by Hodge cycles on X ×X. The m...

Background: Multidrug-resistant Acinetobacter baumannii is associated with life threatening nosocomial infections and hospital outbreaks. The organism is resistant to most commonly used antibiotics including carbapenems. Aim and Objectives: To study carbapenemase production among multidrug-resistant clinical isolates of A. baumannii. Material and Methods: Fifty multidrug-resistant A. baumannii ...

background and objectives: klebsiella pneumoniae is an opportunistic pathogen responsible for up to 10% of nosocomial infections. the emergence and spread of multidrug resistant k. pneumoniae , mostly due to the production of extended-spec- trum β-lactamases (esbl) and carbapenemases, is often responsible for antibiotic treatment failure of these infections. we compared the antibiotic resistanc...

OBJECTIVE The New Delhi metallo-β-lactamase-1 (NDM-1) enzyme is a plasmid-encoded enzyme that inactivates carbapenem antibiotics. This study aims to ascertain if the modified Hodge test (MHT) has a role in screening for NDM-1 in Enterobacteriaceae with reduced carbapenem susceptibility. METHODS Over a period of one year, all Enterobacteriaceae isolates from all clinical specimens with reduced...

The goal of this expository article is first of all to show that Hodge theory provides naturally defined subvarieties of any moduli space parameterizing smooth varieties, the “Hodge loci”, although only the Hodge conjecture would guarantee that these subvarieties are defined on a finite extension of the base field. We will show how these subsets can be studied locally in the Euclidean topology ...

The purpose of this study was to detect carbapenemase genes in clinical isolates of carbapenem-resistant Enterobacteriaceae (CRE) obtained from patients admitted to Hua-Hin Hospital, Prachuab Khiri Khan Province, Thailand between January and December 2014. Screening of CRE was initially determined using disk diffusion method, and subsequently using modified Hodge test (MHT). Multiplex PCR was e...

Given a variation of Hodge structure over P with Hodge numbers (1, 1, . . . , 1), we show how to compute the degrees of the Deligne extension of its Hodge bundles, following Eskin–Kontsevich–Möller–Zorich, by using the local exponents of the corresponding Picard– Fuchs equation. This allows us to compute the Hodge numbers of Zucker’s Hodge structure on the corresponding parabolic cohomology gro...
