Погребальный обряд является одним из важнейших маркеров, позволяющих наиболее точно и достоверно охарактеризовать особенности мировоззрения представителей древних сообществ. В статье предпринята попытка выявить специфику погребального обряда прибрежных культур южноамериканского континента – пайхан (12800–9600 л.н.) и лас-вегас (10800–6600 л.н.), а также очертить возможные перспективы его изучения. Автор дает характеристику современного подхода к изучению погребений: для работы с костными останками активно привлекаются специалисты в области антропологии, генетики, проводятся исследования для определения характера повреждения костей, идентификации по гендерному признаку, диагностики патологий и т.д.

This paper develops an agentic framework that employs large language models (LLMs) for grounded persuasive language generation in automated copywriting, with real estate marketing as a focal application. Our method is designed to align the generated content with user preferences while highlighting useful factual attributes. This agent consists of three key modules: (1) Grounding Module, mimicking expert human behavior to predict marketable features; (2) Personalization Module, aligning content with user preferences; (3) Marketing Module, ensuring factual accuracy and the inclusion of localized features. We conduct systematic human-subject experiments in the domain of real estate marketing, with a focus group of potential house buyers. The results demonstrate that marketing descriptions generated by our approach are preferred over those written by human experts by a clear margin while maintaining the same level of factual accuracy. Our findings suggest a promising agentic approach to automate large-scale targeted copywriting while ensuring factuality of content generation.

Abstract The common hamster (Cricetus cricetus) occupies a controversial position among mammals inhabiting agricultural areas, as it is possibly the only critically endangered species that is legally targeted by lethal control methods, making it a conflict‐generating pest. We surveyed various stakeholders, agrarian consultants, wildlife rangers, and residents for the first time in Hungary, with two interrelated questionnaires to obtain accurate information about hamster populations, and to learn about the participants knowledge of, and attitude toward hamsters in order to provide fundamental information for planning and strengthening social embeddedness. Additionally, we prepared the current distribution map of the hamster. Based on the relatively wide distribution and locally high abundance of the species, Hungary has a key role in hamster conservation. We identified several factors, which can contribute to successful species protection. The results indicated that more than 60% of the respondent's liked hamsters. In contrast, only a few residents considered hamsters in their settlement to be beneficial. Our results suggest that the hamster's reputation is disproportionately negative due to vaguely known perceptions of harm as compared with actual reported damage. This imbalance could be rectified through enhanced communication efforts. Improving the species' reputation is integral to effective species conservation initiatives. Current pest control practices (poisons and snap traps) kill the hamsters, even though 82% of the residents would prefer to keep the hamsters alive, conforming to conservation efforts. The results also indicated that the hamster could be a flagship species in Hungary. Knowledge of the protected status of the hamster predicted a positive attitude toward the species and related to nature conservation consciousness. We conclude that requirements of residents should be included in the species action plan along with the experts' knowledge, as this could contribute to successful, long‐term conservation of the hamster.

The timeline of the expansion rate ultimately defines the interplay between high energy physics, astrophysics and cosmology. The guiding theme of this topical review is provided by the scrutiny of the early history of the space-time curvature through the diffuse backgrounds of gravitational radiation that are sensitive to all the stages of the evolution of the plasma. Due to their broad spectrum (extending from the aHz region to the THz domain) they bridge the macroworld described by general relativity and the microworld of the fundamental constituents of matter. It is argued that during the next score year the analysis of the relic gravitons may infirm or confirm the current paradigm where a radiation plasma is assumed to dominate the whole post-inflationary epoch. The role of high frequency and ultra-high frequency signals between the MHz and the THz is emphasized in the perspective of quantum sensing. The multiparticle final state of the relic gravitons and its macroscopic quantumness is also discussed with particular attention to the interplay between the entanglement entropy and the maximal frequency of the spectrum.

The increasing demand for the web-based digital assistants has given a rapid rise in the interest of the Information Retrieval (IR) community towards the field of conversational question answering (ConvQA). However, one of the critical aspects of ConvQA is the effective selection of conversational history turns to answer the question at hand. The dependency between relevant history selection and correct answer prediction is an intriguing but under-explored area. The selected relevant context can better guide the system so as to where exactly in the passage to look for an answer. Irrelevant context, on the other hand, brings noise to the system, thereby resulting in a decline in the model's performance. In this paper, we propose a framework, DHS-ConvQA (Dynamic History Selection in Conversational Question Answering), that first generates the context and question entities for all the history turns, which are then pruned on the basis of similarity they share in common with the question at hand. We also propose an attention-based mechanism to re-rank the pruned terms based on their calculated weights of how useful they are in answering the question. In the end, we further aid the model by highlighting the terms in the re-ranked conversational history using a binary classification task and keeping the useful terms (predicted as 1) and ignoring the irrelevant terms (predicted as 0). We demonstrate the efficacy of our proposed framework with extensive experimental results on CANARD and QuAC -- the two popularly utilized datasets in ConvQA. We demonstrate that selecting relevant turns works better than rewriting the original question. We also investigate how adding the irrelevant history turns negatively impacts the model's performance and discuss the research challenges that demand more attention from the IR community.

Combining Supernovae, Baryon Acoustic Oscillations and Redshift-Space Distortions data from the next generation of (Stage-IV) cosmological surveys, we aim to reconstruct the expansion history up to large redshifts using forward-modeling of $f_{\mathrm DE}(z) = ρ_\mathrm{DE}(z)/ρ_\mathrm{DE,0}$ with Gaussian processes (GP). In order to reconstruct cosmological quantities at high redshifts where few or no data are available, we adopt a new approach to GP which enforces the following minimal assumptions: a) Our cosmology corresponds to a flat Friedman-Lemaître-Robertson-Walker (FLRW) universe; b) An Einstein de Sitter (EdS) universe is obtained on large redshifts. This allows us to reconstruct the perturbations growth history from the reconstructed background expansion history. Assuming various DE models, we show the ability of our reconstruction method to differentiate them from $Λ$CDM at $\gtrsim2σ$.

In this article, we consider a viscoelastic plate equation with past history, nonlinear damping, and logarithmic nonlinearity. We prove explicit and general decay rate results of the solution to the viscoelastic plate equation with past history. Convex properties, logarithmic inequalities, and generalised Young's inequality are mainly used to prove the decay estimate.

The reliability of surface net heat flux data obtained from the latest satellite-based estimation [the third-generation Japanese Ocean Flux Data Sets with Use of Remote Sensing Observations (J-OFURO3, V1.1)] was investigated. Three metrics were utilized: (1) the global long-term (30 years) mean for 1988–2017, (2) the local accuracy evaluation based on comparison with observations recorded at buoys located at 11 global oceanic points with varying climatological characteristics, and (3) the physical consistency with the freshwater balance related to the global water cycle. The globally averaged value of the surface net heat flux of J-OFURO3 was −22.2 W m−2, which is largely imbalanced to heat the ocean surface. This imbalance was due to the turbulent heat flux being smaller than the net downward surface radiation. On the other hand, compared with the local buoy observations, the average difference was −5.8 W m−2, indicating good agreement. These results indicate a paradox of the global surface net heat flux. In relation to the global water cycle, the balance between surface latent heat flux (ocean evaporation) and precipitation was estimated to be almost 0 when river runoff from the land was taken into consideration. The reliability of the estimation of the latent heat flux was reconciled by two different methods. Systematic ocean-heating biases by surface sensible heat flux (SHF) and long wave radiation were identified. The bias in the SHF was globally persistent and especially large in the mid- and high latitudes. The correction of the bias has an impact on improving the global mean net heat flux by +5.5 W m−2. Furthermore, since J-OFURO3 SHF has low data coverage in high-latitudes areas containing sea ice, its impact on global net heat flux was assessed using the latest atmospheric reanalysis product. When including the sea ice region, the globally averaged value of SHF was approximately 1.4 times larger. In addition to the bias correction mentioned above, when assuming that the global ocean average of J3 SHF is 1.4 times larger, the net heat flux value changes to the improved value (−11.3 W m−2), which is approximately half the original value (−22.2 W m−2).

Abstract:Although by the end of the first century AD the Mediterranean Sea had become a purely Roman sea, in later periods following the rise of the Sassanid, as they sought to reclaim the lands of their ancestors, this empire's confrontation with Byzantium became inevitable. By developing and consolidating their dominance over the political-commercial sphere of the Persian Gulf, Sassanid held an important part of the main transportation and trade axes of the ancient world. This was while on the borders of the other two areas, namely from Mesopotami to the eastern shores of the Mediterranean and the general area of the Caucasus, with their aggressive policy, they had a serious competition with the Byzantines, which was to get the main home, the conflicting ligaments.This research intends to deal with the main causes and factors of the Iran-Byzantine conflict between the Mediterranean Sea and the Persian Gulf by descriptive-analytical method. In order to answer this question, the geopolitical and commercial-economic importance of the disputed areas is discussed. It will also show how the geopolitical position of these lands led the two great powers of that time into a series of land and sea battles.

Object-Oriented Ontology (OOO) is a contemporary form of realism concerned with the investigation of “objects” broadly construed. It may be characterised in terms of a metaphysical pluralism to the extent that it recognises infinitely many different kinds of emergent entities, and this fact in turn leads to a number of questions concerning the nature of objects and emergence in OOO: what is the precise meaning of an emergent entity in OOO? How has emergence been denied throughout the history of Western thought? Is there a specific object-oriented account of emergence? What is the causal mechanism which provides the conditions of possibility for the generation of emergent entities? In this article, I aim to answer all these questions by constructing the first extensive account of real emergence in the context of Object-Oriented Ontology, and I also seek to tie this analysis to the notion of “vicarious” or indirect causation.

This article explores the relationship between “permanent” exhibitions and political flux. Offering a close reading of London’s Commonwealth Institute and its intriguing gallery floor plan of 1969, it considers the interaction between display, exhibition graphics, and imperial change. While the British Empire crumbled (reforming in more clandestine guises), and new nation-building programmes took place around the world, the Commonwealth Institute became a dynamic site of neo-imperial and nationalist agendas, with diplomats, designers, and educators from Asia and beyond all working to re-territorialise, redistribute, and challenge British hegemony. Through this history of the Commonwealth and its exhibitions, the article offers broader lessons on the possibilities and limits of an exhibition’s ephemeral archive, the embodied, fragile nature of exhibition making, and the limits of ‘decolonisation’ as a productive term in the current drive to develop socially just exhibitions.

Sediment cores from three sites along the east-coast of Sweden, north-western Baltic Proper, have been studied with respect to lithologies, geochemistry, and diatom assemblages to trace and date early human impact with emphasis on nutrient discharge. The three sites Bråviken, Himmerfjärden, and Ådfjärden, have been impacted to various degree during the last millennia by multiple stressors like excessive nutrient discharge and hazardous substances, leading to coastal hypoxia, eutrophication, and pollution. These stressors are mainly caused by drivers in the drainage area as increased human population, changed land use, and point sources as industries and a sewage treatment plant. Even though their detailed history differs, the results show similar general patterns for all three sites. We find no evidence in our data from the coastal zone supporting the hypothesis that the extensive areal distribution of hypoxia in the open Baltic Sea during the Medieval Climate Anomaly was caused by human impact. Timing of the onset of man-made eutrophication, as identified from δ15N and changes in diatom composition, differs between the three sites, reflecting the site specific geography and local environmental histories of these areas. The onset of eutrophication dates to ~1800 CE in Bråviken and Himmerfjärden areas, and to ~1900 CE in the less urban area of Ådfjärden. We conclude that the recorded environmental changes during the last centuries are unique in a thousand year perspective.

This study investigates the psychometric properties of a well-set form of the Rational-Experiential Inventory (REI) for adolescents (REI-A20). Participants were 746 Iranian high school students (412 males, 334 females), selected through multistage sampling method. After subjecting our data to principal components analysis (PCA) and parallel analysis (PA), we found a two-factor structure corresponding to rational and experiential processing. Both rational and experiential scales of the REI-A20 exhibited good internal consistency. These two factors accounted for 37% of the variance. The fit indices of confirmatory factor analysis (CFA) confirmed the cross-validity of the inventory. Rationality, but not experientiality, was significantly related to better school performance, elaboration, organization, and metacognitive strategies. Males scored significantly higher on rational scale, but there was no difference between females and males in scores on experiential scale. This new inventory has reliable scores, and allows for valid inferences in assessing individual differences in adolescents’ preference for the rational and experiential information-processing styles.

Deliblato sands is an isolated foreststeppe area of about 350 km2 within the agricultural area of the South East Pannonian Plain. In this area, 200 years ago, people began to foresting sand dunes in order to ban sheep grazing in the second half of the last century and continue to afforest open grasslands with steppe-pasture biocenoses. This jeopardized many sparsed species of mammals and birds, in particular Eastern Imperial Eagle (EIE) (Aquila heliaca). In the period brtween 1963–1967 in the central parts of the Deliblato sands, 5 nests of the EIE pairs were distributed (localities: V. Kravan, Ćarlika, Orlovo gnezdo, Crni Vrh and Plop). A detailed monitoring of the entire bird fauna, especially the EIE in the reproductive period, started in 1976 and ended in 1986. Given that complete data on this monitoring have  not been published until today, for more than 20 years we do not have scientifically verified data on nesting of this species, also Deliblato sands continues to be a potential breeding area for the EIE, I have decided to present the old data, in order to point out the necessity of organizing and conducting a comprehensive and long-term search and monitoring, which has not been done until today.
