A phyletically rare gene promotes the niche-specific fitness of an E. coli pathogen during bacteremia. [PDF]

open access: yesPLoS Pathogens, 2013
In bacteria, laterally acquired genes are often concentrated within chromosomal regions known as genomic islands. Using a recently developed zebrafish infection model, we set out to identify unique factors encoded within genomic islands that contribute ...

Innovative CMOS-fabricated dielectrophoretic chip: application of 3D TiN nano-electrode arrays with adjustable electrode spacing in sperm capture

open access: yesFrontiers in Bioengineering and Biotechnology
Introduction: Dielectrophoresis has been considered an effective method for particle sorting, and scientists have used it to manipulate sperms. However, due to the limitations of the chip fabrication, the conventional dielectrophoresis chip would face ...

Comparison of Kernel equating methods under NEAT and NEC designs

open access: yesInternational Journal of Assessment Tools in Education, 2023
In this study, Kernel test equating methods were compared under NEAT and NEC designs. In NEAT design, Kernel post-stratification and chain equating methods taking into account optimal and large bandwidths were compared.

Neat embeddings as adjoint situations

open access: yes, 2013
We view the neat reduct operator as a functor that lessens dimensions from CA_{\alpha+\omega} to CA_{\alpha} for infinite ordinals \alpha. We show that this functor has no right adjoint. Conversely for polyadic algebras, and several reducts thereof, like

Reconsideration of Second Harmonic Generation from neat Air/Water Interface: Broken of Kleinman Symmetry from Dipolar Contribution

open access: yes, 2005
It has been generally accepted that there are significant quadrupolar and bulk contributions to the second harmonic generation (SHG) reflected from the neat air/water interface, as well as common liquid interfaces.

Asymmetric Hydrogenation in Water by a Rhodium Complex of Sulfonated 2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl (binap) [PDF]

open access: yes, 1993
The synthesis of sulfonated 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (binap) is reported; a rhodium complex of this ligand is the first to perform asymmetric hydrogenation in neat water with optical yields as high as those obtained in nonaqueous ...
