Direct Air Carbon Capture and Storage (DACCS) can mitigate hard-to-abate emissions, e.g. from transport or industry. However, there is a wide variety of cost estimates for DACCS, driven, to a significant extent, by differences in electricity cost. At the same time, there is a notable gap in research that integrates direct air capturing systems into long-term energy system models. We separate direct air capturing, carbon transport, and carbon storage and integrate them into a European capacity expansion model for a fully decarbonised electricity system in 2050. We explore how two dimensions affect the total system costs of DACCS. The first dimension is the availability of CO2 storage locations: In one analysis, storage locations are restricted to offshore storage locations in the North Sea only, i.e. depleted natural gas fields. The alternative analysis comprises suitable storage locations distributed across Europe, including onshore. We find that limiting CO2 storage to North Sea sites increases overall capture costs by approximately 10 %. The second dimension is whether DACCS is analysed as stand-alone or integrated into the electricity system. We differentiate between three alternatives: fully isolated, fully integrated, and retrospectively added to an existing system. We find that neglecting system integration - i.e. treating direct air capture system as a stand-alone technology - increases capture costs by up to 30 %.
We present a method for analyzing general time series by employing the history state formalism of quantum mechanics. This formalism allows us to describe a complete evolution based on a single quantum state, the history state, which simultaneously includes -also as a quantum system- the reference clock. It naturally leads to the concept of system-time entanglement, with the ensuing entanglement entropy constituting a measure of the effective number of distinguishable states visited in the history. Through a quantum coherent state embedding of the time series data, it is then possible to associate a quantum history state to the series. The gaussian overlap between these coherent states provides thus a smooth measure of distinguishability between the series data. The eigenvalues of the corresponding overlap matrix determine in fact the entanglement spectrum and entropy of the history state, which provide a rigorous characterization of the evolution. As illustration, the formalism is applied to typical financial time-series data. Through the entanglement entropy and spectrum, different evolution regimes can be identified. Entanglement based volatility indicators are also derived, and compared with standard volatility measures.
his study reflects on mental illness in selected printed sources by Jakub Fischer, who was the head of the psychiatric department at the Regional Hospital in Bratislava (now the University Hospital on Miczkiewiczova Street). This hospital was one of the first psychiatric facilities in what is now Slovakia. The study describes the approach and functioning of this department, which was one of the pioneering medical institutions in the territory of the then Hungary, based on chosen sources. These sources also provide an insight into mental health and related issues in the period before the collapse of the Austro-Hungarian Empire.
The aim of the article: The evolution of a post-socialist satellite city in Central Europe. A historical and socio-spatial case study of Luboń near Poznań (Poland) is a socio-economic and spatial analysis of the development process of a satellite city with an industrial and agricultural core located in Central Europe.
Luboń is a city founded in 1954, which allows to trace the entire process of its development, based on the research methods used, including statistical data on changes in, among others, population numbers, as well as spatial data based on georeferencing of photographic images of archival maps of the City of Luboń. The methods used as the way of describing and analyzing the history of the city were inscribed in the philosophy of the evolutionary approach referring to the dynamics of change and the complexity of development processes and their imbalance.
The authors of the article formulate answers of three research questions: (1) how did the industrialization origins and socio-spatial alterations shape satellite city contemporary form? (2) how was its spatial form affected by the de-industrialization process of the first decade after 1989? (3) how has the city changed under the demographic and suburbanization pressure of its larger neighbour over the years?
The article also contains elements of historical analysis, reconstructing urban dynamics. It also includes elements of conceptualisation based both on genetic studies of the concept of “new cities”, but also on assumptions present in Soviet urban planning thought, which was a direct inspiration for the solutions of the 1950s.
The generalizations, after answering the research questions, proposed in the conclusion indicate the existence of the state of crisis and invite to discuss the dynamics of the phenomena of metropolisation from the point of view of peripheral participants of the process.

Extended reality can weave together the fabric of the past, present, and future. A two-day design hackathon was held to bring the community together through a love for history and a common goal to use technology for good. Through interviewing an influential community elder, Emile Pitre, and referencing his book Revolution to Evolution, my team developed an augmented reality artifact to tell his story and preserve on revolutionary's legacy that impacted the University of Washington's history forever.
Algebraic quantum field theory (AQFT) puts forward three "causal axioms" that aim to characterize the theory as one that implements relativistic causation: the spectrum condition, microcausality, and primitive causality. In this paper, I aim to show, in a minimally technical way, that none of them fully explains the notion of causation appropriate for AQFT because they only capture some of the desiderata for relativistic causation I state or because it is often unclear how each axiom implements its respective desideratum. After this diagnostic, I will show that a fourth condition, local primitive causality (LPC), fully characterizes relativistic causation in the sense of fulfilling all the relevant desiderata. However, it only encompasses the virtues of the other axioms because it is implied by them, as I will show from a construction by Haag and Schroer (1962). Since the conjunction of the three causal axioms implies LPC and other important results in QFT that LPC does not imply, and since LPC helps clarify some of the shortcomings of the three axioms, I advocate for a holistic interpretation of how the axioms characterize the causal structure of AQFT against the strategy in the literature to rivalize the axioms and privilege one among them.
Political relations between Warsaw and Prague in 1989 were influenced by the disproportion between the rate of the systemic changes taking place in both countries and the critical stance of the KSČ leadership towards the changes taking place in Poland. The negative assessment of the decision to convene the Round Table talks, the capitulating attitude of the PZPR, which de facto agreed to abandon the principles of socialism in the economy and accepted the strengthening of the Solidarity opposition, influenced the reduction of official political contacts, especially in the second half of 1989. This also applied to cooperation between social organisations, especially youth organisations, cultural cooperation and individual border traffic. All these issues were perceived by PLR diplomats making attempts to counteract the isolation by party activists of various levels and trying to counteract the unfavourable presentation of Poland in the Czechoslovak media and supporting their citizens subjected to persecution by Czechoslovak border guards

The bespopovtsy are Orthodox Christians without clergy. They hold the belief that the reign of the Antichrist on earth invalidates the priesthood and sacraments (except baptism) of any Christian Church. This belief emerged in response to the liturgical reforms undertaken by the Orthodox Church in Muscovy, which they deem to have introduced unacceptable alterations to traditional rites. Consequently, the bespopovtsy contend that following the death of the last clergymen ordained according to the rite preceding the reform, genuine priests no longer exist in the world, leaving Jesus Christ as the sole guiding priest for believers. Bespopovtsy communities are organized into communes overseen by regulators, and their places of worship are termed molenna. Due to the absence of a clerical hierarchy, various distinct communities rapidly evolved within the bespopovtsy group.

This paper presents the results of an extensive study investigating the opinions on Artificial Intelligence (AI) of a sample of 4,006 European citizens from eight distinct countries (France, Germany, Italy, Netherlands, Poland, Romania, Spain, and Sweden). The aim of the study is to gain a better understanding of people's views and perceptions within the European context, which is already marked by important policy actions and regulatory processes. To survey the perceptions of the citizens of Europe we design and validate a new questionnaire (PAICE) structured around three dimensions: people's awareness, attitude, and trust. We observe that while awareness is characterized by a low level of self-assessed competency, the attitude toward AI is very positive for more than half of the population. Reflecting upon the collected results, we highlight implicit contradictions and identify trends that may interfere with the creation of an ecosystem of trust and the development of inclusive AI policies. The introduction of rules that ensure legal and ethical standards, along with the activity of high-level educational entities, and the promotion of AI literacy are identified as key factors in supporting a trustworthy AI ecosystem. We make some recommendations for AI governance focused on the European context and conclude with suggestions for future work.
We propose a novel method to quantify the assembly histories of dark matter halos with the redshift evolution of the mass-weighted spatial variance of their progenitor halos, i.e. the protohalo size history. We find that the protohalo size history for each individual halo at z~0 can be described by a double power-law function. The amplitude of the fitting function strongly correlates to the central-to-total stellar mass ratios of descendant halos. The variation of the amplitude of the protohalo size history can induce a strong halo assembly bias effect for massive halos. This effect is detectable in observation using the central-to-total stellar mass ratio as a proxy of the protohalo size. The correlation to the descendant central-to-total stellar mass ratio and the halo assembly bias effect seen in the protohalo size are much stronger than that seen in the commonly adopted half-mass formation time derived from the mass accretion history. This indicates that the information loss caused by the compression of halo merger trees to mass accretion histories can be captured by the protohalo size history. Protohalo size thus provides a useful quantity to connect protoclusters across cosmic time and to link protoclusters with their descendant clusters in observations.
We introduce REmap-eu.app, a web-based data-mining visualization tool of the spatial and temporal variability of wind resources. It uses the latest open-access dataset of the daily wind capacity factor in 28 European countries between 1979 and 2019 and proposes several user-configurable visualizations of the temporal and spatial variations of the wind power capacity factor. The platform allows for a deep analysis of the distribution, the crosscountry correlation, and the drivers of low wind power events. It offers an easy-to-use interface that makes it suitable for the needs of researchers and stakeholders. The tool is expected to be useful in identifying areas of high wind potential and possible challenges that may impact the large-scale deployment of wind turbines in Europe. Particular importance is given to the visualization of low wind power events and to the potential of cross-border cooperations in mitigating the variability of wind in the context of increasing reliance on weather-sensitive renewable energy sources.
U radu se kombinacijom historijske analize mreža i metode udaljenog čitanja iz perspektive historije emocija ispituje sposobnost manevriranja Pavla Rittera Vitezovića unutar više različitih emocionalnih zajednica. Pritom se kao glavni izvor za digitalnotekstualnu analizu koriste Vitezovićeve latinske pjesničke poslanice upućene stvarnim adresatima u razdoblju od 1701. do 1703. godine, no uzima se u obzir i čitav korpus njegovih poslanica nastalih u razdoblju od 1676. do 1712. godine. U radu se kritički testira mogućnost korištenja pristupa udaljenog čitanja ili makroanalize na manjoj količini teksta u kombinaciji s kvalitativnom analizom odnosno "pomnim čitanjem" kao analitički prosede za historijsko-emocionološka istraživanja.

BackgroundAccessible nutrition resources tailored to patients with cancer, caregivers of cancer survivors, and people interested in cancer prevention are limited. Cook for Your Life is a bilingual (ie, English and Spanish) website providing science-based, nutrition information for people affected by cancer.
ObjectiveThe aim of this study was to describe the characteristics of Cook for Your Life website users.
MethodsIn December 2020, Cook for Your Life website visitors at least 18 years old were invited to participate in an online English-language survey. A Spanish version was offered in April 2021. Demographic, health, and cooking characteristics were collected. Persons with a cancer history were asked about treatment and side effects. Data were analyzed through December 2021 on those completing over half of the survey. Three groups were compared: people with a history of cancer diagnosis, caregivers of cancer survivors, and the general public (ie, people without a cancer history). Website use data were also compared.
ResultsAmong English-language respondents, 3346 initiated the survey and 2665 (79.65%) completed over half of the questions. Of these, 54.82% (n=1461) had a cancer diagnosis, 8.26% (n=220) were caregivers, and 36.92% (n=984) were from the general public. English-language respondents were US residents (n=2054, 77.07%), with some from Europe (n=285, 10.69%) and Canada (n=170, 6.38%). Cancer survivors were most likely 55 years of age or older, female, non-Hispanic White, with incomes over US $100,000, and college educated. Caregivers and the general public were younger and more racially and geographically diverse. The most common cancer malignancies among English-language cancer survivors were breast (629/1394, 45.12%) and gastrointestinal (209/1394, 14.99%). For Spanish-language respondents, 942 initiated the survey; of these, 681 (72.3%) were analyzed. Of the 681 analyzed, 13.5% (n=92) were cancer survivors, 6.8% (n=46) were caregivers, and 79.7% (n=543) were from the general public. Spanish-language respondents were also more likely to be female and highly educated, but were younger, were from South or Latin America, and had incomes less than US $30,000. Among Spanish-language cancer survivors, breast cancer (27/81, 33%) and gastrointestinal cancer (15/81, 19%) were the most common diagnoses. Website use data on over 2.2 million users from December 2020 to December 2021 showed that 52.29% of traffic was in English and 43.44% was in Spanish. Compared to survey respondents, a higher proportion of website users were male, younger, and from South or Central America and Europe.
ConclusionsCook for Your Life website users were demographically, socioeconomically, and geographically diverse, especially English-language respondents without a cancer history and all Spanish-language respondents. Improvements on website user diversity and reach for all patients with cancer and research on effective strategies for using this digital platform to support cancer prevention, treatment, and survivorship will continue.

The concept of the ethnographic principle is rarely found in the literature, and there is hardly a legal qualification for it. However, historical material (in cases of the Lithuanian, Czech, Bulgarian and Polish peoples) indicates that the ethnographic principle is a significant political and geopolitical phenomenon. This phenomen is especialy characteristic of the development of the peoples of the region of Central and Eastern Europe. First, the ethnographic principle was closely related to the national principle, although it did not coincide with it. The concept of the ethnographic principle points to the special anatomy of nation states, where the basis is ethnic / linguistic culture. Secondly, the advancement of culture to the fore indicated the recognition of its significance, which had not happened before. Consequently, it was a question of freeing this culture from the restrictions imposed on it and even compensating for the damage caused to it. Thirdly, the culture, raised to the state level, needed appropriate guarantees for the future. The article reveals the tendency of great states at the level of their policies and propaganda to act according to the ethnographic principle, thereby encouraging the formation of national states. However, when the latter became a fact, another tendency arose: the Western world began to apply the criteria of a liberal civil society to new states (according to the principle of jus civis romanus sum). This was too hard for the new states. In this context, the alternative was the Soviet ethno-federalist protectorate, which, although under the conditions of a repressive system, actually continued to implement the projections of the ethnographic principle. A fixed paradox: the ethnographic principle, which originated in the West as a variant of democratization, gained strength thanks to Russia, while the West remained, as it were, in aristocratic opposition to this course. The ethnographic principle has not yet acquired a clearer legal legitimacy. But as a historical category, it can serve as a study of the history of Modern times, and especially the Soviet period.

We present a novel approach to the parallelization of the parabolic fast multipole method for a space-time boundary element method for the heat equation. We exploit the special temporal structure of the involved operators to provide an efficient distributed parallelization with respect to time and with a one-directional communication pattern. On top, we apply a task-based shared memory parallelization and SIMD vectorization. In the numerical tests we observe high efficiencies of our parallelization approach.
