Extended symmetry groups of multidimensional subshifts with hierarchical structure
(American Institute of Mathematical Sciences, 2020)
The centralizer (automorphism group) and normalizer (extended symmetry group) of the shift action
inside the group of self-homeomorphisms are studied, in the context of certain Z(d) subshifts with a
hierarchical supertile ...
Antimicrobial Resistance Patterns and Dynamics of Extended-Spectrum beta-Lactamase-Producing Uropathogenic Escherichia coli in Cusco, Peru
(MDPI, 2021)
Urinary tract infections (UTIs) are a common human infection. Antibiotic resistance in extended-spectrum beta-lactamase (ESBL)-producing uropathogenic E. coli (UPEC) is a major therapeutic challenge due to limited treatment ...

SPECIFYING ACTIVE RULES FOR DATABASE MAINTENANCE
(SPRINGER, 2000)
In this article we extend previous work on the development of logical foundations for the specification of the dynamics of databases. In particular, we deal with two problems. Firstly, the derivation of active rules that ...
Conductor Temperature Estimation and Prediction at Thermal Transient State in Dynamic Line Rating Application
(Institute of Electrical and Electronics Engineers, 2018-10)
The traditional methodology for defining the ampacity of overhead lines is based on conservative criteria regarding the operating conditions of the line, leading to the so-called static line rating. Although this procedure ...
Extended tachyon field, Chaplygin gas, and solvable k-essence cosmologies
(American Physical Society, 2004-12)
We investigate a flat Friedmann-Robertson-Walker spacetime filled with k essence and find the set of functions F that generate three different families of extended tachyon fields and Chaplygin gases. They lead to accelerated ...
