Modelling of Traffic Noise Along Urban Corridor: A Case Study of Amman

open access: yesCivil and Environmental Engineering, 2021
Noise became one of the main environmental indicators of the quality of urban life. The aim of this study was to develop a traffic noise model for an arterial road in Amman, the capital of Jordan, which was being subjected to a persistent increase in ...

Noise characterization of an Optical Frequency Comb using Offline Cross-Correlation

open access: yes, 2016
Using an offline cross-correlation technique, we have analyzed the noise behavior of a new type of optical frequency comb (OFC), which is carrier envelope offset (CEO) free by configuration, due to difference frequency generation.

Metrology and 1/f noise: linear regressions and confidence intervals in flicker noise context [PDF]

open access: yes, 2015
1/f noise is very common but is difficult to handle in a metrological way. After having recalled the main characteristics of stongly correlated noise, this paper will determine relationships giving confidence intervals over the arithmetic mean and the ...

Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, EarlyView.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

Cram\'er-Rao bounds for synchronization of rotations [PDF]

open access: yes, 2013
Synchronization of rotations is the problem of estimating a set of rotations R_i in SO(n), i = 1, ..., N, based on noisy measurements of relative rotations R_i R_j^T.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Audible noise analysis of 750‐kV AC transmission line in high‐altitude area under different weather

open access: yesIET Generation, Transmission & Distribution, 2023
In order to build UHV AC transmission lines at high altitudes, it is necessary to analyze the audible noise (AN) characteristics of the existing EHV transmission lines at high‐altitude areas to guide the design.

Internal noise measurements [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1979
The purpose of this study is to compare two ways of estimating the ratio of internal noise variability to external noise variability (σ1/σE). One method [D. M. Green, Psychol. Rev. 71, 1392–1407 (1964)] infers internal noise from the consistency a listener shows in choosing between two different noise maskers when the same pair are repeated on another ...

Differential regulation of ZFAS1 splice variants by endoplasmic reticulum stress in hepatocyte cell lines

open access: yesFEBS Open Bio, EarlyView.
ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...
