It is with great satisfaction that we present the report of the work carried out during the 8th Meeting “Readings of Hegel's Logic”, which is consolidating itself as a fundamental space for deepening Hegelian thought. This online event, held on May 23 and 24, 2024, via the Zoom platform, brought together scholars, teachers and students dedicated to Hegel's work, in particular the “Science of Logic”, providing moments of interaction and interpretation.

Climate Futures for Lizards and Snakes in Western North America May Result in New Species Management Issues.

We assessed changes in fundamental climate-niche space for lizard and snake species in western North America under modeled climate scenarios to inform natural resource managers of possible shifts in species distributions. We generated eight distribution models for each of 130 snake and lizard species in western North America under six time-by-climate scenarios. We combined the highest-performing models per species into a single ensemble model for each scenario. Maps were generated from the ensemble models to depict climate-niche space for each species and scenario. Patterns of species richness based on climate suitability and niche shifts were calculated from the projections at the scale of the entire study area and individual states and provinces, from Canada to Mexico. Squamate species' climate-niche space for the recent-time climate scenario and published known ranges were highly correlated (r = 0.81). Overall, reptile climate-niche space was projected to move northward in the future. Sixty-eight percent of species were projected to expand their current climate-niche space rather than to shift, contract, or remain stable. Only 8.5% of species were projected to lose climate-niche space in the future, and these species primarily occurred in Mexico and the southwestern U.S. We found few species were projected to lose all suitable climate-niche space at the state or province level, although species were often predicted to occupy novel areas, such as at higher elevations. Most squamate species were projected to increase their climate-niche space in future climate scenarios. As climate niches move northward, species are predicted to cross administrative borders, resulting in novel conservation issues for local landowners and natural resource agencies. However, information on species dispersal abilities, landscape connectivity, biophysical tolerances, and habitat suitability is needed to contextualize predictions relative to realized future niche expansions.

The effects of climate and population on human land use patterns in Europe from 22ka to 9ka ago

Between 22ka and 9ka ago, after the Last Glacial Maximum (LGM) and during the transition to the Holocene, mobile hunter-gatherer populations, differentiated by their stone tool assemblages, periodically dispersed and contracted across Europe. It is well understood that climate played an important role in human distributions and population sizes during the post-LGM Late Pleistocene and Early Holocene, but the question remains as to whether increasing population sizes drove early human dispersal. Here, using a spatiotemporal species distribution model to infer the fundamental and potential human climatic niche space of Late Upper Paleolithic, Final Paleolithic and Early Mesolithic Europe, and hypotheses derived from the Ideal Distribution Model, we test i) how changes in climate affected the size and extent of the projected potential human niche space, ii) for effects of changes in size of projected potential niche on regional human population sizes, iii) whether increasing human population sizes drove human dispersal into less climatically suitable habitats, and iv) whether populations associated with different high-order material culture groupings (macro-level technocomplexes) occupied different climatic spaces. We find that changes in climate correlate strongly with the size and extent of the projected potential human niche space, that increases in the projected human niche space correlate with increases in human population, that human population size is just beginning to become large enough to influence land use and dispersal patterns at the Pleistocene-Holocene transition, and that archaeological technocultural entities overlap in their fundamental climatic niche space. This overlap implies that changing tools forms cannot readily been seen as reflecting adaptations to changing climates.

Harnessing graph state resources for robust quantum magnetometry under noise

Precise measurement of magnetic fields is essential for various applications, such as fundamental physics, space exploration, and biophysics. Although recent progress in quantum engineering has assisted in creating advanced quantum magnetometers, there are still ongoing challenges in improving their efficiency and noise resistance. This study focuses on using symmetric graph state resources for quantum magnetometry to enhance measurement precision by analyzing the estimation theory under time-homogeneous and time-inhomogeneous noise models. The results show a significant improvement in estimating both single and multiple Larmor frequencies. In single Larmor frequency estimation, the quantum Fisher information spans a spectrum from the standard quantum limit to the Heisenberg limit within a periodic range of the Larmor frequency, and in the case of multiple Larmor frequencies, it can exceed the standard quantum limit for both noisy cases. This study highlights the potential of graph state-based methods for improving magnetic field measurements under noisy environments.

Preface

3rd National Forum on Contemporary Space Research (NaFSKI 2022), November 10-12, 2022, Sofia TechPark, Bulgaria The National Forum on Contemporary Space Research is an initiative of the “Cosmos” Branch of the Union of Physicists in Bulgaria aiming to promote space research networking both on national and international levels. The event was shaped as a platform where the Bulgarian academia and industry meet, discuss, and collaborate. The Forum is held under the auspices of the Bulgarian Ministry of Innovation and Growth with the financial support of EnduroSat, Space Fluent, and Sfera Technologies. The first edition of the Forum took place in 2020 and it proved the idea is timely and successful. The second and third editions of the Forum was organized as a 3 days event in Sofia TechPark “Incubator” in October 2021 and attracted even more attention. Thus, it was natural to continue the Forum as annual event and to hold the fourth edition in October 2022. The program and presentations during the Forum are available at https://bulgarianspace.online/nafski2023/ The NAFSKI 2023 Forum programme was a two-days event, aiming at bringing the industrial, research, and education sectors closer together. The event was in three general themes: Space science, Space technologies and Space education, with representatives of the three sectors collaborating in all sections. The collected papers passed a peer-review process, and we are proud to present the collection to the readers of the Journal of Physics – Conference Series. The papers are separated in three categories, according to the topic: fundamental space science research, aerospace technologies and Earth observations. We are thankful to all participants, sponsors, and guests, who contributed to the Forum and helped us to fulfil one of the most recognized events in this scientific topic this year - without you this would never have happened. We are looking forward to welcoming you again at the fifth edition in October 2024. Assoc. Prof. Dr.-Ing.

Punishment and (In)sensitivity at the Security Border

This article expands on David Garland’s proposal that punitive practices are influenced by logics of (in)sensitivity, shaping how punishment is conceived and applied. It argues that (in)sensitivity is not a mere peripheral aspect of punishment but a central element thereof. Drawing from this premise, the article elucidates the most prominent features of Garland’s proposition, highlighting the conceptual framework it builds upon. Based on this foundation, the discussion branches into two closely related directions. Firstly, it analytically explores Garland’s contribution, explicating the depth underlying notions of meaning and sensitivity; a development that will underscore the significance of corporeality in fully understanding the imposition of punishment. Secondly, this analysis will be projected onto the context of the current discursive hegemony of security and, more specifically, in the specific manner it manifests in the regulation of migrant mobility. The undeniable preeminence of securitized borders will thus become the fundamental space of analysis to project Garland’s proposal regarding an underlying (in)sensitivity permeating the imposition of punishment. Within this context, it asserts that migrant bodies crossing the border endure punishment, yet their suffering lacks empathy within the security discourse.

The Neanderthal niche space of Western Eurasia 145 ka to 30 ka ago

Neanderthals occupied Western Eurasia between 350 ka and 40 ka ago, during the climatically volatile Pleistocene. A key issue is to what extent Neanderthal populations expanded into areas of Western Eurasia and what conditions facilitated such range expansions. The range extent of Neanderthals is generally based on the distribution of Neanderthal material, but the land-altering nature of glacial periods has erased much of the already sparse material evidence of Neanderthals, particularly in the northern latitudes. To overcome this obstacle species distribution models can estimate past distributions of Neanderthals, however, most implementations are generally constrained spatially and temporally and may be artificially truncating the Neanderthal niche space. Using dated contexts from Neanderthal sites from across Western Eurasia, millennial-scale paleoclimate reconstructions, and a spatiotemporal species distribution model, we infer the fundamental climatic niche space of Neanderthals and estimate the extent of Neanderthal occupation. We find that (a.) despite the long timeframe, Neanderthals occupy a relatively narrow fundamental climatic niche space, (b.) the estimated projected potential Neanderthal niche space suggests a larger geographic range than the material record suggests, and (c.) that there was a general decline in the size of the projected potential Neanderthal niche from 145 ka ago onward, possibly contributing to their extinction.

HOW INTELLIGENT TECHNOLOGIES ARE CHANGING SOCIETY AND THE SPACE OF A BIG CITY

The study examines the evolution of the urban environment in the context of the third and, in the XXI century, the fourth industrial revolution. Special attention is paid to the changes taking place in big cities under the influence of digitalization, modern information technologies and social needs of society. The work describes the formation of communities and communities that arise in the virtual space and are transferred to the urban environment. Exhibitions, as part of the fundamental space of large cities, are a public metamodern filled with cultural and innovative capitalist forms. For the first time, the concept of the chronotope and its role as a driving force uniting time and space in the formation of culture, public life and the development of urban spaces is used. The study highlights changes in social connections, the emergence of new forms of communication and the impact of technological progress on urban dynamics. In general, the paper analyzes the evolution of the urban environment and exhibition activities under the influence of modern technologies, socio-cultural changes and identifies key trends and challenges facing modern cities.

Systematic research is needed on the potential effects of lifelong technology experience on cognition: a mini-review and recommendations.

Digital technology now occupies a fundamental space in human life. Increasingly sophisticated access to information and social interactions has enabled a sort of offloading of many aspects of cognition, and for many people, this technology use has been lifelong. While the global development of technologies advances exponentially as part of the Fourth Industrial Revolution, researchers have not yet fully characterized the human effects of this technology-centric revolution at the same pace. In this mini-review, we consider three important higher-level cognitive functions: creativity, adaptability, and decision-making, and discuss their potential relationship to lifelong digital technology experience, which here includes both passive exposure and active use of electronic devices. We then articulate the gaps in related literature and knowledge, and outline general considerations, suggestions, and challenges for future research avenues. In general, we found that prior research has investigated uses of specific technology products on lower-level cognition (e.g., how does the use of online search engines affect memory?), but there is a lack of research assessing the overall effects of technology experience on cognitive functioning, particularly complex cognition.

Tensor force impact on shell evolution in neutron-rich Si and Ni isotopes* *This study was supported by the Interdisciplinary Scientific and Educational School of Moscow University's "Fundamental and Applied Space Research." Sidorov S.V. expresses his gratitude for the support provided by the Foundation for the Development of Theoretical Physics and Mathematics "BASIS."

The influence of the tensor interaction of nucleons on the characteristics of neutron-rich silicon and nickel isotopes was studied in this work. Tensor forces are considered within the framework of the Hartree-Fock approach with the Skyrme interaction. The addition of a tensor component of interaction is shown to improve the description of the splittings between different single-particle states and decrease nucleon-nucleon pairing correlations in silicon and nickel nuclei. Special attention was directed toward the role of isovector tensor forces relevant to the interaction of like nucleons.

3D in High-D

According to the high-dimensional approach to quantum mechanics (a.k.a. wavefunction realism), the fundamental space of our world has an unfathomably large number of dimensions. This account is empirically adequate only if the three-dimensional manifest image can somehow be recovered from high-dimensional reality. A proper understanding of inter-level metaphysics (a.k.a. metaphysical explanation, grounding, etc.) shows that the manifest image can indeed be recovered, and answers the most concerning objections to high-dimensionalism. But it also shows that high-dimensionalism has disturbing consequences about the objectivity of the manifest image.

Voices on the air: Speech education and campus radio in the postcolonial Philippine university

In the late 1950s and throughout the 1960s, faculty and students of the newly organized Department of Speech and Drama (later Department of Speech Communication and Theatre Arts) at the University of the Philippines (UP) were at the forefront of managing the radio station DZUP, mounting radio productions on campus and shaping the academic curricula for classes in radio speech and writing. These pioneering contributions, though significant, have yet to receive due documentation from communication scholars, researchers, and historians in the country. In this essay, I address this gap by bringing into focus archival documents—photographs, newspaper accounts, official memos, and personal correspondences between academics and administrators—that clarify the academic department’s role in the early systems and operations of DZUP. I argue that these efforts are important because of four main reasons. First, they highlight the often-overlooked relationship between speech education and campus radio in the national university. Second, they emphasize the ways in which the radio booth worked alongside the public speaking platform and the theatre stage as a fundamental space where speech-related pedagogies, performances, and practices played out. Third, they show disciplinary genealogy that links the disciplines of speech communication and mass communication in the University of the Philippines. And finally, they shed light on the pedagogical process involved in teaching, training, and transforming Filipino students into a kind of speaking subjects in the postcolonial Philippines.

Topological Vector Spaces Derived From Topological Hypervector Spaces

We introduce topological hypervector spaces on a topological field, in the sense of Tallini, and study some basic properties of this hyperspaces. In this regards we study the relationship between the topology on a hypervector spaces and its complete part. In particular we show that if every open subset of a topological hypervector space is a complete part then its fundamental vector space induced is a topological vector space. Finally, we study the quotient space of topological hypervector spaces and the derived topological space of a topological hypervector space with respect its fundamental relegation.

Rituals Within Walls: Thinking Post-War Japan’s History through Cinematic Allegories of Everyday Life

Between the mid-1960s and the early 1970s, the quotidian dimension took political centrality in Japan thanks to the leading role of the New Left movement and its ideology. This went hand in hand with an appreciation of the philosophical approaches of Marxist intellectuals such as Jun Tosaka and Gorō Hani, who saw the quotidian as a fundamental space for historical transformation. We know how Tosaka and Hani developed an everyday-centred philosophy of history through their writings, but we know little about how formats other than the written word – such as cinema – contributed to thinking historical reality from the same ideological approach. To address this gap in our understanding, this article analyses the intersection of two highly representative films with Tosaka and Hani’s historical thought: Secrets Within Walls ( Kabe no naka no himegoto, Kōji Wakamatsu, 1965) and Ceremonies ( Gishiki, Nagisa Ōshima, 1971). These films’ cinematic allegorisation of post-war Japan’s everyday relationships was a way to reflect on the political character of that period.

Vector Control Technology of Five‐Phase Induction Motor without Speed Sensor Based on Speed‐Adaptive Full‐Order Observer

The five‐phase induction motor, being the most elementary form of multiphase induction motors, boasts low noise, low torque fluctuations, and high load‐bearing capacity, and is hence suitably employed in domains where high power and reliability are required. In light of the susceptibility of the speed encoder to interference from external environments, this paper proposes a sensorless vector control technique for the five‐phase induction motor based on a speed‐adaptive full‐order observer. The proposed approach first employs the nearest four‐vector space vector pulse width modulation (NFV‐SVPWM) as the modulation technique for the five‐phase inverter, in order to provide a constant switching frequency and low harmonic losses. Subsequently, the expression for the speed‐adaptive full‐order observer is constructed based on the mathematical model of the fundamental space of the five‐phase induction motor, and the expression for the adaptive speed law is deduced using the Lyapunov function. Additionally, the bilinear transformation method is utilized as the discretization technique for the full‐order observer during the process of digital implementation, in order to achieve higher discrete accuracy. Finally, an experimental study involving a 4.5 kW five‐phase induction motor was conducted to validate the accuracy and effectiveness of the proposed method. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

The paradigm «human rights – municipal human rights – municipal person» and its defining role in the formation and functioning of the legal space of local self-government

The conceptual problems of the formation, existence and functioning of the management paradigm «human rights – municipal human rights – municipal man» are considered and its determining role in the formation and functioning of the legal space of local self-government is determined. The process and conditions of formation of the legal space of local self-government and the significance of this process for democratic legal statehood, as well as for local self-government and the territorial community are studied. The identified features – constitutional legalization, power-prognostic, spatial-belonging, existential-fundamental, behavioral-behavioral, state-local, communication, transformational-spatial, national-globalization, local-human rights protection, democratic technological – clearly demonstrate that the profile paradigm not only organically fits into the given system of features, thanks to: a) the local nature of the emergence, manifestation, use and realization of human rights, b) the local formation, manifestation and realization of municipal human rights, as well as c) purely local identification of the emergence, emergence, formation and manifestation of the phenomenology of «municipal man», but also actively forms and effectively builds the corresponding technological-social and functional-normative chain, which has a high theoretical-praxeological and communication-implementation potential, which is optimal, effective and implemented at the level of local society in the conditions of local self-government and within the boundaries of the territorial community. It is proved that the profile paradigm has not only a significant doctrinal, but also a powerful managerial potential, which determines its defining role in the formation and functioning of the legal space of local self-government, and, thanks to the deep humanitarian and humanistic content, the constituent elements of the profile paradigm arise, are formed and are implemented in local society, the processes of self-organization of the population, which are accompanied by multiplicative processes of self-organization, self-identification, self-activity, self-management, and self-governance of each resident-member of the territorial human community, which actually objectifies, expands, dynamizes, optimizes, intensifies, and improves the legal space of local democracy in the form of a local self-government and leads to the formation of its various species characteristics that illustrate and demonstrate the fundamental existential spheres of existence, functioning and manifestation of the interests of the human territorial community. Key words: territorial community, a person in a territorial community, local self-government, human rights, municipal human rights, phenomenology «municipal person», legal space of local self-government, specific characteristics of local self-government spaces, administrative support of local self-government, existential spaces of local self-government, fundamental space of local self-government, human interests in local self-government, behavioral principles of the legal space of local self-government, operational principles of the legal space of local self-government, technological principles of the legal space of local self-government, municipal-prospective principles of the legal space of local self-government, municipal-legal consciousness, management paradigm «human rights – municipal human rights – a municipal person».

Topographic representation of visually evoked emotional experiences in the human cerebral cortex

Affective neuroscience seeks to uncover the neural underpinnings of emotions that humans experience. However, it remains unclear whether an affective space underlies the discrete emotion categories in the human brain, and how it relates to the hypothesized affective dimensions. To address this question, we developed a voxel-wise encoding model to investigate the cortical organization of human emotions. Results revealed that the distributed emotion representations are constructed through a fundamental affective space. We further compared each dimension of this space to 14 hypothesized affective dimensions, and found that many affective dimensions are captured by the fundamental affective space. Our results suggest that emotional experiences are represented by broadly spatial overlapping cortical patterns and form smooth gradients across large areas of the cortex. This finding reveals the specific structure of the affective space and its relationship to hypothesized affective dimensions, while highlighting the distributed nature of emotional representations in the cortex.

Dual-Band High-Efficiency Power Amplifier Based on a Series of Inverse Continuous Modes With Second-Harmonic Control

This letter proposes a design approach for a dual-band (DB) power amplifier (PA) based on a series of inverse continuous modes (SICMs). The approach possesses a wider fundamental and second-harmonic impedance space compared with inverse continuous class-F, and the dual bandwidths of the DB PA can be improved flexibly. In addition, a variable knee voltage is considered for predicting the output performance of the PA more accurately. A simple impedance control network only for the second-harmonic is exploited to improve PA efficiency. Simulation and measurement results indicate that the fabricated DB PA achieves drain efficiencies of 65%–80.9% from 2.43 to 2.70 GHz, and 65%–76.2% from 3.37 to 3.52 GHz, respectively, and the obtained output power exceeds 10 W in DBs.
