Radio-frequency impedance measurements using a tunnel-diode oscillator (TDO) technique

open access: yes, 1999
A resonant method based on a tunnel-diode oscillator (TDO) for precision measurements of relative impedance changes in materials, is described. The system consists of an effective self-resonant LC-tank circuit driven by a forward-biased tunnel diode ...

Disentangling 2:1 resonant radial velocity orbits from eccentric ones and a case study for HD 27894 [PDF]

open access: yes, 2015
In radial velocity observations, a pair of extrasolar planets near a 2:1 orbital resonance can be misinterpreted as a single eccentric planet, if data are sparse and measurement precision insufficient to distinguish between these models. We determine the

Preliminary findings on the experimental investigation of the small-strain behaviour of Pizzoli silty sand [PDF]

open access: yesE3S Web of Conferences
The dynamic properties of soils play a crucial role in solving many geotechnical problems with special attention to earthquake engineering. In particular, the small-strain soil behavior should be accurately reproduced in geotechnical modelling to allow ...

Investigation of long-wavelength elastic wave propagation through wet bentonite-filled rock joints

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
The saturation of the compacted bentonite buffer in the deep geological repository can cause bentonite swelling, intrusion into rock fractures, and erosion.

Evaluation of the damping ratio of compacted sodium and calcium bentonites in unsaturated conditions

open access: yesSoils and Foundations
Bentonites are going to be part of the Engineered Barrier System (EBS) in deep geological disposal facilities for the safe disposal of spent nuclear fuel.

A scalar hint from the diboson excess?

open access: yes, 2015
In view of the recent diboson resonant excesses reported by both ATLAS and CMS Collaborations, we suggest that a new weak singlet pseudo-scalar particle, $\eta_W$, may decay into two weak bosons while being produced in gluon fusion at the LHC.

Laboratory Investigation of the Mechanical Properties of a Rubber–Calcareous Sand Mixture: The Effect of Rubber Content

open access: yesApplied Sciences, 2020
This paper introduces a rubber–calcareous sand mixture as a lightweight building material in offshore engineering. The mechanical properties of mixtures of varying rubber contents were investigated by performing a one-dimensional (1-D) compression test ...

Quantifying resonant activation like phenomenon in non-Markovian systems

open access: yes, 2014
Resonant activation is an effect of a noise-induced escape over a modulated potential barrier. The modulation of a energy landscape facilitates the escape kinetics and makes it optimal as measured by the mean first passage time.

Stability of three-dimensional relativistic jets: implications for jet collimation [PDF]

open access: yes, 2010
The stable propagation of jets in FRII sources is remarkable if one takes into account that large-scale jets are subjected to potentially highly disruptive three-dimensional (3D) Kelvin-Helmholtz instabilities.

Time-Dependent Behavior of Lyman$\alpha$ Photon Transfer in High Redshift Optically Thick Medium

open access: yes, 2011
With Monte Carlo simulation method, we investigate the time dependent behavior of Ly$\alpha$ photon transfer in optically thick medium of the concordance $\Lambda$CDM universe.
