Retraction of DNA-bound type IV competence pili initiates DNA uptake during natural transformation in Vibrio cholerae

open access: yesNature Microbiology, 2018
Natural transformation is a broadly conserved mechanism of horizontal gene transfer in bacterial species that can shape evolution and foster the spread of antibiotic resistance determinants, promote antigenic variation and lead to the acquisition of ...

ICESsuHN105, a Novel Multiple Antibiotic Resistant ICE in Streptococcus suis Serotype 5 Strain HN105

open access: yesFrontiers in Microbiology, 2019
Streptococcussuis serotype 5, an emerging zoonosis bacterial pathogen, has been isolated from infections in both pigs and humans. In this study, we sequenced the first complete genome of a virulent, multidrug-resistant SS5 strain HN105.

Fourier transformation of Sato's hyperfunctions [PDF]

open access: yes, 2004
A new generalized function space in which all Gelfand-Shilov classes $S^{\prime 0}_\alpha$ ($\alpha>1$) of analytic functionals are embedded is introduced.

Water Disinfection Byproducts Increase Natural Transformation Rates of Environmental DNA in Acinetobacter baylyi ADP1.

open access: yesEnvironmental Science and Technology, 2019
The process of natural transformation allows for the stable uptake, integration, and functional expression of extracellular DNA. This mechanism of horizontal gene transfer has been widely linked to the acquisition of antibiotic resistance and virulence ...

The natural affinors on generalized higher order tangent bundles [PDF]

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 2001
For integers r ≥ 1 and n ≥ 2 and a real number a < 0 the natural affinors on the generalized higher order tangent bundle T(r),a and on the extended generalized higher order tangent bundle E(r),a over n-manifolds are classified.

Ginsparg-Wilson Fermions in Odd Dimensions [PDF]

open access: yes, 2000
The Ginsparg-Wilson relation, if written in a suitable form, can be used as a condition for lattice Dirac operators of massless fermions also in odd dimensions.

Lie groupoids and their natural transformations [PDF]

open access: yesDifferential Geometry and its Applications, 2020
We discuss natural transformations in the context of Lie groupoids, and their infinitesimal counterpart. Our main result is an integration procedure that provides smooth natural transformations between Lie groupoid morphisms.

The gonococcal genetic island and type IV secretion in the pathogenic Neisseria

open access: yesFrontiers in Cellular and Infection Microbiology, 2011
Eighty percent of Neisseria gonorrhoeae strains and some Neisseria meningitidis strains encode a 57 kb gonococcal genetic island (GGI). The GGI was horizontally acquired and is inserted in the chromosome at the replication terminus. The GGI is flanked by

Two-Dimensional Conformal Models of Space-Time and Their Compactification [PDF]

open access: yes, 2006
We study geometry of two-dimensional models of conformal space-time based on the group of Moebius transformation. The natural geometric invariants, called cycles, are used to linearise Moebius action.

Natural state transformations

open access: yesJournal of Computer and System Sciences, 1975
The concept of generalized3 sequential machines in arbitrary categories is developed in the paper. The change in viewpoint from the previous studies comes from the appropriate choice of a monoidal category. Thus a monad, rather than a monoid in the category of sets, becomes the crucial notion of this development.
