Frequency tuning, nonlinearities and mode coupling in circular graphene resonators

, 2013
We study circular nanomechanical graphene resonators by means of continuum elasticity theory, treating them as membranes. We derive dynamic equations for the flexural mode amplitudes.

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Role of Self-Assembled Monolayers on Improved Electrical Stability of Amorphous In-Ga-Zn-O Thin-Film Transistors

, 2014
Self-assembled monolayers (SAMs) have been used to improve both the positive and negative bias-stress stability of amorphous indium gallium zinc oxide (IGZO) bottom gate thin film transistors (TFTs).

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

FEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Origin of back stress generation during tensile deformation of a heterostructured titanium alloy: An in-situ EBSD study on local slip system activation

Journal of Materials Research and Technology
Revealing the origin of back stress generation is important for the design of heterostructured metals and alloys. Here, we study the back stress generation during tensile deformation in a heterostructured Ti–6Al–4V alloy via in-situ scanning electron ...

Stress Echocardiography: Back to the Future

Revista Argentina de Cardiologia, 1992
Some lines of research seem today very promising for a possible clinical application in stress echocardiography in the near future. These include transesophageal echocardiography, operator-independent quantification of regional wall motion, tissue characterization, and contrast echocardiography.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Tunnel Back Analysis Based on Differential Evolution Using Stress and Displacement

Advances in Civil Engineering, 2020
The stability of tunnels has mainly been evaluated based on displacement. Because displacement due to the excavation process is significant, back analysis of the structure and ground can be performed easily. Recently, the length of a segment-lined tunnel
