Vision-based Deformation Measurement for Pile-soil Testing [PDF]

open access: yesMATEC Web of Conferences, 2019
Image measurement technology has been widely used in monitoring the deformation of the soil field around the pile with its advantages of no damage, no contact, full-field measurement, no added quality and high sensitivity. But there are few researches on

Non-Contact Thickness Measurement With EDS

open access: yes, 2022
Abstract In this work we deal with a method of non-destructive layers thickness measurement using a scanning electron microscope (SEM) equipped with an energy dispersive spectrometer (EDS). This method was chosen for ease of use in all laboratories equipped with the SEM with the EDS detector.

Energy Measurements and Preparation of Canonical Phase States of a Nano-Mechanical Resonator

open access: yes, 2007
We show that a continuous quantum non-demolition measurement of the energy of a nanomechanical resonator can be achieved by monitoring the resonator with a quantum point contact via a Cooper-pair box.

High cumulants in the counting statistics measured for a quantum dot [PDF]

open access: yes, 2009
We report on measurements of single electron tunneling through a quantum dot using a quantum point contact as non-invasive charge detector with fast time response.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Four-point probe measurements using current probes with voltage feedback to measure electric potentials

open access: yes, 2017
We present a four-point probe resistance measurement technique which uses four equivalent current measuring units, resulting in minimal hardware requirements and corresponding sources of noise.

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

P1.3 - Measuring System for Non-Contact Oscillation Measurement

open access: yesProceedings SENSOR 2009, Volume II, 2009
This paper summarizes the investigations and results of an R&D project concerning a measuring system for a non-contact amplitude and direction measurement of periodic and aperiodic lateral device oscillations. It is based on the detection and analysis of scattered light speckle patterns caused by rough surfaces and can be manufactured at low costs ...

Non-contact thickness measurement using UTG [PDF]

open access: yes, 1996
A measurement structure for determining the thickness of a specimen without mechanical contact but instead employing ultrasonic waves including an ultrasonic transducer and an ultrasonic delay line connected to the transducer by a retainer or collar. The

Full counting statistics and conditional evolution in a nanoelectromechanical system

open access: yes, 2008
We study theoretically the full distribution of transferred charge in a tunnel junction (or quantum point contact) coupled to a nanomechanical oscillator, as well as the conditional evolution of the oscillator.
