CryoEM structure of the outer membrane secretin channel pIV from the f1 filamentous bacteriophage
Nature Communications, 2021 The Ff family of filamentous bacteriophages infect gram-negative bacteria, but do not cause lysis of their host cell. Instead, new virions are extruded via the phage-encoded pIV protein, which has homology with bacterial secretins. Here, we determine the

Experimental Study on a Generic Side-View Mirror with Slotted Cylindrical Foot [PDF]
Journal of Applied Fluid Mechanics, 2022 A simple model consisting of a mirror-housing and its cylindrical foot is applied to represent the automobile side-view mirror that causes unwanted aerodynamic noise and wind drag during high-speed driving. An additional slot is made on the solid foot to

Experimental Study of the Particles Influence on the Pyramid Wake within the Turbulent Boundary Layer [PDF]
Journal of Applied Fluid Mechanics, 2022 Particle imaging velocimetry (PIV) was used to study the near-field variation of a pyramid rough element in clear water and a liquid–solid boundary layer (thickness: 60 mm).

Particle image velocimetry (PIV) uncertainty quantification using moment of correlation (MC) plane [PDF]
Measurement science and technology, 2018 We present a new uncertainty estimation method for particle image velocimetry (PIV), that uses the correlation plane as a model for the probability density function (PDF) of displacements and calculates the second order moment of the correlation (MC ...

Securing All intraVenous devices Effectively in hospitalised patients—the SAVE trial: study protocol for a multicentre randomised controlled trial [PDF]
, 2015 Introduction: Over 70% of all hospital admissions have a peripheral intravenous device (PIV) inserted; however, the failure rate of PIVs is unacceptably high, with up to 69% of these devices failing before treatment is complete.

Strategies Developed to Induce, Direct, and Potentiate Bone Healing
Frontiers in Physiology, 2017 Bone exhibits a great ability for endogenous self-healing. Nevertheless, impaired bone regeneration and healing is on the rise due to population aging, increasing incidence of bone trauma and the clinical need for the development of alternative options ...

IET Power Electronics, EarlyView., 2022 The article discusses the novel topology with high gain and low voltage stress DC‐DC converter based on switched‐capacitor and switched‐inductors for fuel cell and PV applications. The converter performance is analyzed and verified with the hardware prototype (22/400V, 50kHz).

Is there introspective evidence for phenomenal intentionality? [PDF]
, 2016 The so-called transparency of experience (TE) is the intuition that, in introspecting one’s own experience, one is only aware of certain properties (like colors, shapes, etc.) as features of (apparently) mind-independent objects.
