Exciton and multiexciton optical properties of single InAs/GaAs site-controlled quantum dots
2013
We have studied the optical properties of InAs site-controlled quantum dots (SCQDs) grown on pre-patterned GaAs substrates. Since InAs nucleates preferentially on the lithography motifs, the location of the resulting QDs is determined by the pattern, which is fabricated by local oxidation nanolithography. Optical characterization has been performed on such SCQDs to study the fundamental and excited states. At the ground state different exciton complex transitions of about 500 μeV linewidth have been identified and the fine structure splitting of the neutral exciton has been determined (≈65 μeV). The observed electronic structure covers the demands of future quantum information technologies.…
Czy Peirce był konserwatystą?
2015
The main aim of this paper is to consider from different points of view the thesis of a conservative character of Peirce’s thought. The paper consists of two parts. In the first part, arguments for Peirce’s conservatism are presented. They are of two kinds: inner ones (Peirce’s own declarations) and outer ones (a comparison of Peirce’s view o the views of two other classical pragmatists: James and Dewey). The second part of the paper is devoted to counterarguments – the main one is the fact that Peirce is an author of the conception of an unlimited community of inquirers. This conception was an inspiration to the vision of the world and social activities which were perceived as unambiguousl…

Driving Mechanism of Corporate Social Responsibility in United States and Mainland China
2017
This paper empirically explored the driving factors of corporate social responsibility (CSR) using survey data from USA and China.Based on the results from a Web survey of more than 400 executives from a diversified sample of companies, the influential CSR drivers betweenUSA and China were compared and contrasted. Factor analysis identifies the ranking of CSR drivers for China as (1) ethics/values, (2) performance, (3)international issues/consumers/reputation, (4) barriers, and (5)government/laws in descending importance. The ranking for USA is (1) ethics/values, (2) barriers,(3) performance, (4) government/ laws, and (5) consumers/reputation. Furthermore, it was found that China being in a…
The Industrial City: The Multi-Ethnic Frontier of the Twentieth Century
2004
Between 1890 and 1920, big American industrial cities represented the frontier for the more than 23 million immigrants from southern and eastern Europe, Asia, and Central America, as well as for the African-Americans from the South. The development of mass consumption industries and the interventionism of the federal government provided security at the workplace and a general improvement in living standards for blue collar workers. The local party machines, the industrial unions and the effects of the First World War fully integrated the new immigrants into politics. Mass culture and entertainment made Americanization easier and, together with organised crime, were a quick way of social asc…
Children's exploration of the concepts of home and belonging: Capturing views from five European countries.
2021
Understanding one's sense of belonging is a central part of identity formation and self-awareness; feeling safe somewhere, with specific people is identified as a basic human need. This paper explores the ideas of children from three age groups in five different European as they discussed the concepts of ‘home’ and ‘belonging’. Findings showed that the children's ideas could be organised into six interrelated aspects: Spatiality, Materiality, Multiplicity, Social Relations, Affect, and Dislocation. Whilst there were differences in the ways that the children conceptualised home across the classes, even the youngest children were able to describe their ideas using metaphors and abstract conce…
UAV-Assisted Data Collection in Wireless Sensor Networks: A Comprehensive Survey
2021
Wireless sensor networks (WSNs) are usually deployed to different areas of interest to sense phenomena, process sensed data, and take actions accordingly. The networks are integrated with many advanced technologies to be able to fulfill their tasks that is becoming more and more complicated. These networks tend to connect to multimedia networks and to process huge data over long distances. Due to the limited resources of static sensor nodes, WSNs need to cooperate with mobile robots such as unmanned ground vehicles (UGVs), or unmanned aerial vehicles (UAVs) in their developments. The mobile devices show their maneuverability, computational and energy-storage abilities to support WSNs in mul…
Combined dynamics of the 500–600 nm leaf absorption and chlorophyll fluorescence changes in vivo: Evidence for the multifunctional energy quenching r…
2021
Carotenoids (Cars) regulate the energy flow towards the reaction centres in a versatile way whereby the switch between energy harvesting and dissipation is strongly modulated by the operation of the xanthophyll cycles. However, the cascade of molecular mechanisms during the change from light harvesting to energy dissipation remains spectrally poorly understood. By characterizing the in vivo absorbance changes (Delta A) of leaves from four species in the 500-600 nm range through a Gaussian decomposition, while measuring passively simultaneous Chla fluorescence (F) changes, we present a direct observation of the quick antenna adjustments during a 3-min dark-to-high-light induction. Underlying…
Experimental study of $^{100}$Tc $\beta$ decay with total absorption $\gamma$-ray spectroscopy
2017
International audience; The β decay of Tc100 has been studied by using the total absorption γ-ray spectroscopy technique at the Ion Guide Isotope Separator On-Line facility in Jyväskylä. In this work the new Decay Total Absorption γ-ray Spectrometer in coincidence with a cylindrical plastic β detector has been employed. The β intensity to the ground state obtained from the analysis is in good agreement with previous high-resolution measurements. However, differences in the feeding to the first-excited state as well as weak feeding to a new level at high excitation energy have been deduced from this experiment. Theoretical calculations performed in the quasiparticle random-phase approximatio…
Identification of a dipole band above the Iπ = 31/2- isomeric state in 189Pb
2015
A dipole band of six transitions built upon a firmly established I π = 31/2− isomeric state has been identified in 189Pb using recoil-isomer tagging. This is the lightest odd-mass Pb nucleus in which a dipole band is known. The dipole nature of the new transitions has been confirmed through angular-intensity arguments. The evolution of the excitation energy and the aligned-angular momentum of the states in the new dipole band are compared with those of dipole bands in heavier, odd-mass lead isotopes. This comparison suggests that the new band in 189Pb is based upon a π[s−2 1/2h9/2i13/2]11− ⊗ ν[i −1 13/2+ ]13/2+ configuration. However, the increased aligned-angular momentum in 189Pb may sugg…
