On the Collective Choice among Models of Social Protection: An Experimental Study

open access: yesGames, 2019
A real-effort experiment is conducted in order to detect preferences for one out of three different models of the Welfare State characterized by different tax-and-transfer schemes.

Photon-Photon Correlations as a Probe of Vacuum Induced Coherence Effects [PDF]

open access: yes, 2007
We present new experimental implications of the effects of vacuum induced coherence on the photon -photon correlation in the pi-polarized fluorescence in j = 1/2 to j = 1/2 transition.

On asymptotic structure at null infinity in five dimensions [PDF]

open access: yes, 2010
We discuss the asymptotic structure of null infinity in five dimensional space-time. Since it is known that the conformal infinity is not useful for odd higher dimensions, we shall employ the coordinate based method like the Bondi coordinate firstly ...

Microwave emission by nonlinear crystals irradiated with a high-intensity, mode-locked laser [PDF]

open access: yes, 2016
We report on the experimental investigation of the efficiency of some nonlinear crystals to generate microwave (RF) radiation as a result of optical rectification (OR) when irradiated with intense pulse trains delivered by a mode-locked laser at $1064 ...

Predicting and Rationalizing Piezoelectricity in Racemic Bioorganic Molecular Crystals

open access: yesAngewandte Chemie, EarlyView.
Racemic molecular crystals, composed of equal mixtures of chiral enantiomeric components, are predicted to exhibit significant piezoelectric responses and favourable mechanical flexibility. This study identifies organic and bioorganic racemates as promising candidates for sustainable, lead‐free materials, enabling next‐generation applications in energy

RETRACTED: Income Shocks and Child Mortality Rates: Evidence from Fluctuations in Oil Prices

open access: yesECONOMICS, 2021
Previous studies show that children in lower socioeconomic status families reveal higher rates of mortality. We complement the income-mortality literature by establishing a causal link between income and child mortality.

Influence of pulse poling on the piezoelectric property of Pb(Zr0.52,Ti0.48)O3 thin films

open access: yesAIP Advances, 2014
We have investigated the influence of pulse poling on the piezoelectric property of Pb(Zr0.52,Ti0.48)O3 (PZT) thin films. 1.9-μm-thick PZT thin films were deposited by sol-gel method and fabricated into microelectromechanical systems (MEMS) based ...

Differences in the Income Distribution of Households Run by Men and Women by Voivodeships

open access: yesFolia Oeconomica Stetinensia, 2020
Research background: Household income depends on its demographic composition, age and education of its members, place of residence and many other factors. In our work, we concentrate on the income distribution of Polish households.
