Frame-Free Continuum Thermomechanics

open access: yes, 2018
The principle of material frame-indifference is a fundamental concept in classical physics. In 1972 Walter Noll showed that one can formulate constitutive laws without using any external frames of reference.

Frame-based block sparse compressed sensing via $$l_2/l_1$$ l 2 / l 1 -synthesis

open access: yesEURASIP Journal on Advances in Signal Processing
In this paper, we consider the frame-based block sparse signal recovery via a $$l_2/l_1$$ l 2 / l 1 -synthesis method. A new kind of null space property based on the given dictionary D(block D-NSP) is proposed.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Effect of column base strength on steel portal frames in fire

open access: yes, 2012
In the UK, the design of steel portal frame buildings in fire is based on the Steel Construction Institute (SCI) design method, in which fire protection needs only be provided to the columns, provided that the column bases are designed to resist an ...

Depth perception of stereoscopic transparent stimuli with frame manipulation

open access: yesScientific Reports
Depth perception is crucial in human vision, allowing us to move and interact with our 3-D surroundings. We used a stereoscopic transparent stimulus comprising parallel overlapping transparent stereoscopic surfaces (POTS) to understand depth perception ...

On the nonstationarity of collisionless shocks and its impact on deriving the cross‐shock potential

open access: yesGeophysical Research Letters, 2017
Recently, Comişel et al. (2015) suggested an adaptation of the deHoffmann‐Teller (HT) frame, to take into account the magnetic field fluctuations observed nearby and inside a quasi‐perpendicular collisionless shock.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Non-Winding AODF Cross-Connect Method Based on the Spatial Relationship of Non-Coplanar Lines

open access: yesIEEE Access, 2018
Outdoor communication wiring is mainly used to provide a physical connection between telecommunication services. With many fibers to the X networks having been built to provide high-level reliability services and to reduce operational costs, the operator
