Electron-phonon interaction via Pekar mechanism in nanostructures [PDF]

, 2004
We consider an electron-acoustic phonon coupling mechanism associated with the dependence of crystal dielectric permittivity on the strain (the so-called Pekar mechanism) in nanostructures characterized by strong confining electric fields. The efficiency

The impact of the air-fluorescence yield on the reconstructed shower parameters of ultra-high energy cosmic rays [PDF]

, 2010
An accurate knowledge of the fluorescence yield and its dependence on atmospheric properties such as pressure, temperature or humidity is essential to obtain a reliable measurement of the primary energy of cosmic rays in experiments using the ...

Energy-Dependent Fission-Product Yields in the Region of Second-Chance Fission [PDF]

EPJ Web of Conferences
The energy dependence of high-yield fission products has been measured using quasi-monoenergetic neutron beams at energies between 5.5 and 11.0 MeV. The absolute number of fissions during the irradiation period was determined via dual-fission ionization ...

Specific heat of a PIN-PMN-PT single-crystal up to 500K [PDF]

Journal of Advanced Dielectrics, 2017
The temperature dependence of the specific heat of the single crystal Pb(In0.5Nb0.5)O3-Pb(Mg1∕3Nb2∕3)O3-PbTiO3 (PIN-PMN-PT) was obtained at 80–500K by means of ac-calorimetry, and comparison with the calorimetric data for PMN was made, allowing one to ...

Absolute Seebeck coefficient of thin platinum films

, 2019
The influence of size effects on the thermoelectric properties of thin platinum films is investigated and compared to the bulk. Structural properties, like the film thickness and the grain size, are varied.

Linear Temperature Variation of the Penetration Depth in YBCO Thin Films

, 1995
We have measured the penetration depth $\lambda(T)$ on $\rm YBa_{2}Cu_{3}O_{7}$ thin films from transmission at 120, 330 and 510~GHz, between 5 and 50~K. Our data yield simultaneously the absolute value and the temperature dependence of $\lambda(T)$.

The psychophysics of absolute threshold and signal duration: A probabilistic approach [PDF]

, 2011
The absolute threshold for a tone depends on its duration; longer tones have lower thresholds. This effect has traditionally been explained in terms of ?temporal integration? involving the summation of energy or perceptual information over time.

Outcomes of Live Virus Vaccination in Patients With Vascular Anomalies Being Treated With Sirolimus

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Live vaccination in patients with vascular anomalies (VA) receiving sirolimus remains controversial due to immunosuppressive effects and theoretical risks. Procedure This single‐center retrospective study included patients with VA less than 4 years old at the start of sirolimus therapy who were incompletely vaccinated.

Measurement of Seafloor Acoustic Backscatter Angular Dependence at 150 kHz Using a Multibeam Echosounder

Remote Sensing, 2021
Acoustic seafloor measurements with multibeam echosounders (MBESs) are currently often used for submarine habitat mapping, but the MBESs are usually not acoustically calibrated for backscattering strength (BBS) and cannot be used to infer absolute ...
