PIV-Measurements of Centrifugal Instabilities in a Rectangular Curved Duct with a Small Aspect Ratio

open access: yesFluids, 2021
In this study, experimental measurements were undertaken using non-intrusive particle image velocimetry (PIV) to investigate fluid flow within a 180° rectangular, curved duct geometry of a height-to-width aspect ratio of 0.167 and a curvature of 0.54 ...

The Borrelia afzelii outer membrane protein BAPKO_0422 binds human Factor-H and is predicted to form a membrane-spanning beta-barrel [PDF]

open access: yes, 2015
The deep evolutionary history of the Spirochetes places their branch point early in the evolution of the diderms, before the divergence of the present day Proteobacteria.

Portals to Knowledge: CD-ROM Encyclopaedias, with Specific Reference to Microsoft Encarta 99 Encyclopedia

open access: yesLexikos, 2012
The close interaction between linguistics and lexicography over the last few decades has had many good effects, not least of which has been the development of a theoretical framework or meta lexicography.

Design of Capacitorless DRAM Based on Polycrystalline Silicon Nanotube Structure

open access: yesIEEE Access, 2021
In this study, a capacitorless one-transistor dynamic random-access memory (1T-DRAM) based on a polycrystalline silicon nanotube structure with a grain boundary (GB) is designed and analyzed using technology computer-aided design (TCAD) simulation.

Outer membrane protein size and LPS O-antigen define protective antibody targeting to the Salmonella surface

open access: yesNature Communications, 2020
Lipopolysaccharide (LPS) O-antigen (O-Ag) is known to limit antibody binding to surface antigens, although the relationship between antibody, O-Ag and other outer-membrane antigens is poorly understood.

Structural characterisation of outer membrane proteins from Borrelia burgdorferi sensu lato by small-angle X-ray scattering [PDF]

open access: yes, 2016
Forming the interface between the bacterial cell and the host, the outer membrane of Borrelia is known to play a key role in pathogenicity. Although Borrelia burgdorferi sensu lato are considered to be Gram-negative, their outer membrane is unique ...

A molecular trap inside microtubules probes luminal access by soluble proteins

open access: yesNature Chemical Biology, 2021
The uniquely hollow structure of microtubules (MTs) confers characteristic mechanical and biological properties. Although most regulatory processes take place at the outer surface, molecular events inside MTs, such as α-tubulin acetylation, also play a ...

Subspace Coding for Networks with Different Level Messages

open access: yesEntropy, 2015
We study the asymptotically-achievable rate region of subspace codes for wireless network coding, where receivers have different link capacities due to the access ways or the faults of the intermediate links in the network. Firstly, an outer bound of the
