On the use of shot noise for photon counting [PDF]

open access: yes, 2015
Lieu et al. (2015) have recently claimed that it is possible to substantially improve the sensitivity of radio astronomical observations. In essence, their proposal is to make use of the intensity of the photon shot noise as a measure of the photon ...

Road traffic noise and health-related quality of life: A cross-sectional study

open access: yesNoise and Health, 2013
Evidence is emerging linking environmental noise to health problems. Noise can affect health directly and indirectly: For example, noise sensitivity moderates the effects of noise annoyance, which in turn mediates the effects of noise exposure.

Noise sensitivity of an atomic velocity sensor [PDF]

open access: yes, 2005
We use Bloch oscillations to accelerate coherently Rubidium atoms. The variation of the velocity induced by this acceleration is an integer number times the recoil velocity due to the absorption of one photon. The measurement of the velocity variation is

Average Sensitivity and Noise Sensitivity of Polynomial Threshold Functions [PDF]

open access: yesSIAM Journal on Computing, 2014
We give the first non-trivial upper bounds on the average sensitivity and noise sensitivity of degree-$d$ polynomial threshold functions (PTFs). These bounds hold both for PTFs over the Boolean hypercube and for PTFs over $\R^n$ under the standard $n$-dimensional Gaussian distribution.

An investigation of tinnitus, noise sensitivity and anxiety levels in liver transplantation patients in the early and late periods: A cross-sectional study

open access: yesMedicine Science, 2023
This study aims to evaluate the perception of anxiety, tinnitus, and noise sensitivity in liver transplant patients according to early and late periods following transplantation. The study included 76 patients with liver transplantation.

Strongly quadrature-dependent noise in superconducting micro-resonators measured at the vacuum-noise limit

open access: yes, 2010
We measure frequency- and dissipation-quadrature noise in superconducting lithographed microwave resonators with sensitivity near the vacuum noise level using a Josephson parametric amplifier.

Weak value amplification and beyond the standard quantum limit in position measurements [PDF]

open access: yes, 2015
In a weak measurement with post-selection, a measurement value, called the weak value, can be amplified beyond the eigenvalues of the observable. However, there are some controversies whether the weak value amplification is practically useful or not in ...

Cooperativity, Sensitivity, and Noise in Biochemical Signaling [PDF]

open access: yesPhysical Review Letters, 2008
Cooperative interactions among the binding of multiple signaling molecules is a common mechanism for enhancing the sensitivity of biological signaling systems. It is widely assumed that this increase in sensitivity of the mean response implies the ability to detect smaller signals.

Parent Quality of Life at Two Years Following Their Child's Completion of Acute Lymphoblastic Leukemia Treatment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Parents of children treated for acute lymphoblastic leukemia (ALL) often experience significant caregiver burden and disruption to their well‐being. While parent quality of life (QoL) during treatment is well characterized, little is known about outcomes during early survivorship.

Environmental noise and sleep disturbance: Research in central, eastern and south-eastern Europe and newly independent states

open access: yesNoise and Health, 2013
Countries from South-East Europe (SEE), Central and Eastern Europe (CEE) and Newly Independent States (NIS) are in the process of harmonization with European environmental noise legislation.
