Finite frequency current noise in the Holstein model

, 2017
We investigate the effects of local vibrational excitations in the nonsymmetrized current noise $S(\omega)$ of a nanojunction. For this purpose, we analyze a simple model - the Holstein model - in which the junction is described by a single electronic ...

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Noise emission caused by transport in Trakai city modelling and evaluation / Transporto sukeliamo triukšmo sklaidos Trakų mieste modeliavimas ir vertinimas

Mokslas: Lietuvos Ateitis, 2016
One of the biggest problem in most cities – noise emissions in the environment caused by transport. It is found that environment noise can cause not only discomfort, but it is also harmful to health.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Noise Pollution in Kerman-Iran [PDF]

Iranian Journal of Public Health, 2001
Noise is defined as unwanted or objectionable sound. Human susceptibility to noise varies in terms of intensity, altitude, timbre of sound, personal sensibility, age, and history of ear disorder.

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

, 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.

Nonlinear voltage dependence of shot noise [PDF]

, 1999
The current noise in a multi-probe mesoscopic conductor can have a nonlinear dependence on the strength of driving bias voltage. This paper presents a theoretical formulation for the nonlinear noise spectra.

The masking-level difference in low-noise noise.

The Journal of the Acoustical Society of America, 1996
The masking-level difference for a 500-Hz pure tone signal was examined for an interaurally in-phase noise having different degrees of power fluctuations. MLDs were reliably smaller in noise having relatively low power fluctuations. This effect was due to the following trends in the threshold data. (1) For all subjects, the So threshold improved as the

Crucial parameters for precise copy number variation detection in formalin‐fixed paraffin‐embedded solid cancer samples

Molecular Oncology, EarlyView.
This study shows that copy number variations (CNVs) can be reliably detected in formalin‐fixed paraffin‐embedded (FFPE) solid cancer samples using ultra‐low‐pass whole‐genome sequencing, provided that key (pre)‐analytical parameters are optimized.

Low-frequency Current Fluctuations in Individual Semiconducting Single-Wall Carbon Nanotubes [PDF]

, 2005
We present a systematic study on low-frequency current fluctuations of nano-devices consisting of one single semiconducting nanotube, which exhibit significant 1/f-type noise.
