Optimized linear, quadratic and cubic interpolators for elementary function hardware implementations
(MDPI, 2016-04-08)
This paper presents a method for designing linear, quadratic and cubic interpolators that compute elementary functions using truncated multipliers, squarers and cubers. Initial coefficient values are obtained using a ...
Null-homologous exotic surfaces in 4-manifolds
(2013-10-07)
In this paper we exhibit infinite families of embedded tori in 4-manifolds that are topologically isotopic but smoothly distinct. The interesting thing about these tori is that they are topologically trivial in the sense ...
From zero to sixty in under one year: A practical approach to building new programs and services, managing change, and embracing innovation as a new library administrator
(Library Leadership and Management Association, 2016-11)
New library administrators face several challenges as they tackle bringing change into an existing environment or creating something new. The current literature examines trends within higher education, but there is a ...
Recent studies in microbial degradation of petroleum hydrocarbons in hypersaline environments
(Frontiers Media, 2014-04-23)
Many hypersaline environments are often contaminated with petroleum compounds. Among these, oil and natural gas production sites all over the world and hundreds of kilometers of coastlines in the more arid regions of Gulf ...
Landowners' perceptions of risk in grassland management: Woody plant encroachment and prescribed fire
(Resilience Alliance, 2014)
Ecologists recognize that fire and herbivory are essential to maintaining habitat quality in grassland ecosystems. Prescribed fire and grazing are typically used on public reserves to increase biodiversity, improve grassland ...
Cellular chaperones and folding enzymes are vital contributors to membrane bound replication and movement complexes during plant RNA virus infection
(Frontiers Media, 2012-12-06)
Cellular chaperones and folding enzymes play central roles in the formation of positive-strand and negative-strand RNA virus infection. This article examines the key cellular chaperones and discusses evidence that these ...
σᴺ-dependent control of acid resistance and the locus of enterocyte effacement in enterohemorrhagic Escherichia coli is activated by acetyl phosphate in a manner requiring flagellar regulator FlhDC and the σS antagonist FliZ
(Wiley, 2014-08)
In enterohemorrhagic Escherichia coli (EHEC), sigma factor N (σᴺ) regulates glutamate-dependent acid resistance (GDAR) and the locus of enterocyte effacement (LEE); discrete genetic systems that are required for transmission ...
Genetic modification of alternative respiration in Nicotiana benthamiana affects basal and salicylic acid-induced resistance to potato virus X
(BioMed Central, 2011-02-28)
Background: Salicylic acid (SA) regulates multiple anti-viral mechanisms, including mechanism(s) that may be negatively regulated by the mitochondrial enzyme, alternative oxidase (AOX), the sole component of the alternative ...
In vivo assessment of diet-induced rat hepatic steatosis development by percutaneous single-fiber spectroscopy detects scattering spectral changes due to fatty infiltration
(SPIE, the international society for optics and photonics, 2015-11-05)
This study explores percutaneous single-fiber spectroscopy (SfS) of rat livers undergoing fatty infiltration. Eight test rats were fed a methionine-choline-deficient (MCD) diet, and four control rats were fed a normal diet. ...
PHDcleav: A SVM based method for predicting human Dicer cleavage sites using sequence and secondary structure of miRNA precursors
(BioMed Central, 2013-10-09)
Background: Dicer, an RNase III enzyme, plays a vital role in the processing of pre-miRNAs for generating the miRNAs. The structural and sequence features on pre-miRNA which can facilitate position and efficiency of cleavage ...
