Exploiting ground effects for surface transport noise abatement

open access: yesNoise Mapping, 2016
Growing demand on transportation, road and railway networks has increased the risk of annoyance from these sources and the need to optimise noise mitigation.

Noise identification based on spectral analysis and noisy transfer function approach for fuel cells

open access: yesNoise Mapping, 2020
In this study, some measurements like the current, voltage and hydrogen flow based on the fuel cell are investigated in spectral-domain as well as their time-domain representations and then, their spectral properties are extracted.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Spatial and Temporal Stability of Airglow Measured in the Meinel Band Window at 1191.3 nm [PDF]

open access: yes, 2015
We report on the temporal and spatial fluctuations in the atmospheric brightness in the narrow band between Meinel emission lines at 1191.3 nm using an R=320 near-infrared instrument.

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

open access: yesMolecular 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.

Nonequilibrium charge-Kondo transport through negative-U molecules [PDF]

open access: yes, 2006
Low-temperature transport through molecules with effectively negative charging energy U exhibits a charge-Kondo effect. We explore this regime analytically by establishing an exact mapping between the negative-U and the positive-U Anderson models, which ...

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

open access: yesMolecular 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.

Understanding perceived tranquillity in urban Woonerf streets: case studies in two Dutch cities

open access: yesNoise Mapping
Within the current urbanised society, the call for calm and quiet areas seems more pressing than ever. Such tranquil environments like the Woonerf streets in the Netherlands allow a more human-centred design, where traffic has a restricted speed limit of
