The dressed atom revisited: Hamiltonian-independent treatment of the radiative cascade
Full text linkPreprint artykułuThe dressed atom approach provides a tool to investigate the dynamics of an atom-laser system by fully retaining the quantum nature of the coherent mode. In its standard derivation, the internal atom-laser evolution is described within the rotating-wave approximation, which determines a doublet structure of the spectrum
and the peculiar fluorescence triplet in the steady state. However, the rotating wave approximation may fail to apply to atomic systems subject to femtosecond light pulses, light-matter systems in the strong-coupling regime or sustaining permanent dipole moments. This work aims to demonstrate how the general features of
the steady-state radiative cascade are affected by the interaction of the dressed atom with propagating radiation modes. Rather than focusing on a specific model, we analyze how these features depend on the parameters characterizing the dressed eigenstates in arbitrary atom-laser dynamics, given that a set of general hypotheses is satisfied. Our findings clarify the general conditions in which a description of the radiative cascade in terms of transition between dressed states is self-consistent. We provide a guideline to determine the properties of photon emission for any atom-laser interaction model, which can be particularly relevant when the model should be tailored to enhance a specific line. We apply the general results to the case in which a permanent dipole moment is a source of low-energy emission, whose frequency is of the order of the Rabi coupling.National Science Centre, Poland (Project No. 2020/39/I/ST3/00526

(dostęp: 23.09.2024).We investigate linguistically encoded emotional alignment in pairs of players in a TV game show that is set up as a one-shot prisoner’s dilemma. We measure which linguistically encoded emotional characteristics are relevant for choosing between cooperative and defective behavior in that game. We show that cooperativeness depends on interactions between emotional characteristics of both players. In contrast to research on emotional synchrony and cooperation, however, we find that players are more likely to cooperate if their emotions do not align. We interpret this as an instance of deceptive linguistic behavior.Michael Pleyer was supported by project No. 2021/43/P/HS2/02729 co-funded by the National Science Centre and the European Union Framework Programme for Research and Innovation Horizon 2020 under the Marie Skłodowska-Curie grant agreement No. 945339
Eye tracking as a tool for analysing human -AI image interactions
Full text linkThe text was published in: 2024 Progress in Applied Electrical Engineering (PAEE), Koscielisko, Poland, 2024, pp. 1-3; Publisher: IEEE; DOI: 10.1109/PAEE63906.2024.10701449.In recent years, artificial intelligence (AI) has significantly advanced fields like computer vision, image description, and generation, proving particularly relevant in creative areas such as generative art. This research aimed to explore AI’s capabilities in creating and describing images compared to human perception. It included a comparative analysis of visual perception using eyetracking techniques in two settings: a VR art gallery created for the BITSCOPE project and a stationary ET study of individual images. The images, sourced from the BITSCOPE project’s CHIST-ERA IV collection, were initially described by an expert following specific instructions, which were then used by AI to generate corresponding images. The eyetracking study focused on key areas and gaze plot sequences, using a gaze plot similarity metric based on topology and path length, enabled by the size of the research group.The research is a part of project Bitscope (no. 2021/03/Y/ST6/00002) is supported by the National Science Centre, Poland, under CHIST-ERA IV programme, which has received funding from the EU Horizon 2020 Research and Innovation Programme, under Grant Agreement no. 857925

A Duty to Rescue and Its Cost
Full text linkThis research was funded in whole or in part by the National Science Centre, Poland,
grant number 2020/39/B/HS5/00610. For the purpose of Open Access, the author has
applied a CC-BY public copyright license to any Author Accepted Manuscript (AAM)
version arising from this submission.The purpose of the present paper is to analyse the problem of cost generated by
the performance of a duty to rescue. The authors consider three distinct views of this
problem by confronting a scenario in which one party decides to rescue another,
where providing such assistance seems to involve an infringement upon the property
rights of the third party. For example, A rescues drowning B but in the process of doing
so A apparently trespasses upon C’s land. The question that the authors pose is:
Assuming that there is a duty to rescue, who should be charged with the cost of what
seems to be an infringement upon the third party’s property rights? The paper analyses
the following possibilities: the cost should be borne by (a) the victim of the emergency,
(b) the rescuer, (c) the third party whose rights seem to have been encroached
upon. Even though the authors begin with a pronouncedly libertarian assumption
about the third party’s absolute property rights, in the course of the discussion they
come to the conclusion that it is exactly this assumption that should be further probed
and ultimately relaxed in order to reach the most plausible solution to the present
dilemma.Narodowe Centrum Nauki, NCN/National Science Centre.

Air temperature changes in SW Greenland in the second half of the 18th century
Full text linkThe thermal conditions of south-western Greenland in the second half of the 18th century were estimated using two unique series of meteorological observations. The first series (Neu-Herrnhut, 1 September 1767 to 22 July 1768, hereinafter 1767–1768) is the oldest long-term series of instrumental measurements of air temperature available for Greenland. The second (Godthaab, September 1784 to June 1792) contains the most significant and reliable data for Greenland for the study period. The quality-controlled and corrected data were used to calculate daily, monthly, seasonal and yearly means. The daily means were further used to calculate day-to-day temperature variability (DDTV), thermal seasons, growing degree days (GDDs), the air thawing index (ATI), positive degree days (PDDs) and air freezing index (AFI) degree days. Air temperature in Godthaab (now Nuuk) was, on average, warmer than the present day (1991–2020) in 1767–1768 and colder in 1784–1792. Compared to the early 20th-century Arctic warming (ETCAW) period, the data for the two subperiods show that the late 18th century was as warm or even warmer. Except winter 1767/1768, winters and springs in the study period were longer, while summers and autumns were shorter than at present. The analysed climate indices usually did not exceed the maximum and minimum values from 1991–2020. Mean daily air temperature in the studied historical periods rarely exceed +2 SD (standard deviation) of the long-term mean calculated for the contemporary period. Air temperature distribution was usually close to normal, in both historical and contemporary periods.Narodowe Centrum Nauki (grant no. 2020/39/B/ST10/00653)
Dostęp do sprawiedliwości w ochronie środowiska: zaskarżenie wadliwego planu urządzenia lasu przez organizację ekologiczną – glosa
No full textGlosowane orzeczenie TSUE dotyczy dwóch zagadnień, to jest implementacji dyrektyw siedliskowej i ptasiej w prawie polskim w związku z gospodarką leśną oraz partycypacji społecznej w ochronie środowiska, analizowanej na tle planu urządzenia lasu i oceny jego oddziaływania na obszary Natura 2000. W tym drugim przypadku, TSUE oceniał skutki przenikania się dwóch reżimów prawnych, to jest art. 6 ust. 3 dyrektywy siedliskowej i art. 6 ust. 1 lit. b w zw. z art. 9 ust. 2 konwencji z Aarhus. W kontekście obowiązków państwa członkowskiego, Trybunał podtrzymał dotychczasową interpretację dotyczącą standardu ochrony prawnej (III filar Aarhus), koniecznego do zapewnienia przez prawodawcę krajowego podmiotom indywidualnym, zwłaszcza organizacjom ekologicznym, mogącym uczestniczyć w postępowaniu ocenowym tego rodzaju. Brak możliwości poddania PUL skutecznej kontroli sądowej pod kątem legalności materialnej i/lub proceduralnej przez organizacje ekologiczne, zakwalifikowany został przez TSUE jako naruszenie przez Rzeczpospolitą Polską jej zobowiązań traktatowych. Nie można jednak w pełni podzielić stanowiska TSUE co do podstawy prawnej, gdyż w świetle konwencji z Aarhus dostęp do sprawiedliwości w przypadku polskiego PUL, będącego „planem” a nie „przedsięwzięciem”, winien być wywodzony w oparciu o art. 7-8 w zw. z art. 9 ust. 2 tej umowy międzynarodowej.UMK w Toruni
