title: The early Heidegger's concept of freedom
Creators: name: Feas Perez, Xoana
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: In this dissertation, I read Being and Time (1927) together with some course lectures that Heidegger taught between 1928 and 1930 in order to clarify Heidegger’s early account of freedom. Although the conception of freedom of Being and Time is different from his later account, I argue that they must be understood in terms of one another. In particular, the idea of “transcendental freedom” that Heidegger developed for the first time in 1928, can provide a richer interpretation of his earlier work. In the first two chapters, I explore this account of transcendental freedom. This is, I claim, an ontological account, for it goes beyond the anthropological analysis of Dasein and concerns the ontological question of the meaning of being. In this sense, I argue in the first chapter that freedom, understood as the “freeing” or “opening” of the groundless possibility in terms of which Dasein understands both its own self and the world, is the transcendental condition of our understanding of being and, consequently, the condition of our own self-understanding. In the second chapter, I explore another character of transcendental freedom, namely the withdrawal from alternative possibilities that in each case occurs in freeing one possibility. I claim that for Heidegger it is only by virtue of this withdrawal that Dasein can exist as a particular and constant being. In the final chapter, I explore the idea of freedom presented in Being and Time in the light of the account of transcendental freedom. I argue that, in becoming authentic, Dasein “appropriates” the groundless, null project of transcendental freedom, and it is in this appropriation of the possibilities that it has not chosen that Dasein can “become free.”
Economic Brief 5 - Social Services, Social Welfare, and Community Development in the Arctic
Creators: name: JUSTNORTH
Publisher: name: Zenodo
Year: 2023

description: This JUSTNORTH Economic Brief examines how economic sectors like transportation, resource extraction, and search and rescue impact the social development of Arctic countries and communities. It delves into how these activities can either support or impede the well-being of communities in the region. The analysis covers the governance and regulations concerning public transport, social welfare, corporate responsibility, and search and rescue operations, considering justice and environmental sustainability. Although there's noticeable progress in Arctic social welfare, significant challenges persist, especially regarding employment and coordinated spatial planning.

description: In this diploma thesis, we address the problem of noncoherent synchronization, channel estimation, and detection for offset quadrature phase-shift keying (OQPSK) and binary frequency-shift keying (BFSK) modulations. We develop a gradient-descent algorithm which exploits some characteristics of the concentrated likelihood function (CLF) of the time delay as well as some observations about the transmitted sequences and performs noncoherent synchronization, channel estimation, and detection for the aforementioned types of modulation. The proposed algorithm is based on the efficient noncoherent detection of the transmitted symbols, under channel and timing uncertainty. The development of our algorithm is based on the maximum-likelihood (ML) criterion and utilizes state-of-the-art noncoherent detection techniques from the literature. After we reproduce the results of a recent work on joint noncoherent synchronization, channel estimation, and detection for OQPSK, we design an algorithm that concentrates on the data detection problem and is applicable for both OQPSK and BFSK. We are mainly interested in the transmitted sequence but a clock estimate is obtained as byproduct. The latter is achieved by converting the likelihood function to a form that depends only on the estimates of the transmitted sequences and the actual channel delay. The method used involves the first-order derivative of the likelihood with respect to the delay as well as some useful properties of the estimated sequences.

description: The spin dynamics of the layered square-lattice vanadate Pb2VO(PO4)2 is investigated by electron spin resonance at various magnetic fields and at temperatures above magnetic ordering. The linewidth divergence towards low temperatures seems to agree with isotropic Heisenberg-type spin exchange suggesting that the spin relaxation in this quasi-two dimensional compound is governed by low-dimensional quantum fluctuations. However, a weak easy- plane anisotropy of the g factor points to the presence of a planar XY type of exchange. Indeed, we found that the linewidth divergence is described best by XY-like spin fluctuations which requires a single parameter only. Therefore, ESR-probed spin dynamics could establish Pb2VO(PO4)2 as the first frustrated square lattice system with XY-inherent spin topological fluctuations.

description: IGR J18179-1621 is an obscured accreting X-ray pulsar discovered by INTEGRAL on 2012 February 29. We report on our 20 ksec Chandra-High Energy Transmission Gratings Spectrometer observation of the source performed on 2012 March 17, on two short contemporaneous Swift observations, and on our two near-infrared (K_s, H_n, and J_n) observations performed on 2012 March 13 and March 26. We determine the most accurate X-ray position of IGR J18179-1621, alpha_{J2000}=18 h 17m 52.18 s, delta_{J2000}=-16^\circ 21', 31.68" (90% uncertainty of 0.6"). A strong periodic variability at 11.82 s is clearly detected in the Chandra data, confirming the pulsating nature of the source, with the lightcurve softening at the pulse peak. The quasi-simultaneous Chandra-Swift spectra of IGR J18179-1621 can be well fit by a heavily absorbed hard power-law N_H =2.2+/-0.3 \times 10^{23} cm^{-2}, and photon index Γ= 0.4+/-0.1) with an average absorbed 2-8 keV flux of 1.4\times 10^{-11} erg cm^{-2} s^{-1}. At the Chandra-based position, a source is detected in our near infrared (NIR) maps with K_s = 13.14+/-0.04 mag, H_n = 16+/-0.1 mag, and no J_n band counterpart down to ~18 mag. The NIR source, compatible with 2MASS J18175218-1621316, shows no variability between 2012 March 13 and March 26. Searches of the UKIDSS database show similar NIR flux levels at epochs six months prior to and after a 2007 February 11 archival Chandra observation where the source's X-ray flux was at least 87 times fainter. In many ways IGR J18179-1621 is unusual: its combination of a several week long outburst (without evidence of repeated outbursts in the historical record), high absorption column (a large fraction of which is likely local to the system), and 11.82 s period does not fit neatly into existing X-ray binary categories.

description: Computation contact mechanics are being found in many applications starting form structures and automotive industry down to powder metallurgy, food industry and pharmaceutical industry. It constitutes an essential framework for the study of materials that are in contact on the fact that provides accurate informations for their properties (i.e stresses distribution), thus plays a crucial role on design and production of end product or products that should undergo additional modication. The classical base for the treatment of several contact problems was provided from Hertz theory (1882) that delivered the analytical solution of the contact between two elastic materials.
This diploma thesis aims to display the above theory by a) presenting its framework b) comparing results with its analytical solution and those coming form nite element software c) applying discrete element method to deal with contact problems and at the same time a new idea that extents classical theory will be presented.

description: Previous deliverables D4.1 Initial Methodology for Designing and Developing NetApps [1] and D4.2 Final Methodology for Designing and Developing NetApps [2] have described in detail the methodology NetApp developers are following while designing and developing their NetApps. First practical outcomes of the design process are, for each single NetApp, reported and discussed in this deliverable. In an attempt to make the deliverable genuine in reporting the progress, it also includes certain sections of configuration files.
 The deliverable is primarily focused on reporting the status of creating NetApps, therefore its content follows key methodology topics introduced in D4.1 and D4.2. To better understand the goal of each NetApp, a functional overview is presented first, followed by a short description on the status and next steps regarding the NetApp creation process toward its final stage and demonstration within the 5GASP infrastructure. Since all NetApps are not exactly at the same level of the development, certain differences between them may be observed.
 Within the NetApp analysis section, a list of Network Service Descriptors (NSD) is presented for each Network Service used in a particular NetApp. Similarly, a list of Virtual Network Functions (VNFs), which implements already defined Network Services, is presented as well. The same section also depicts relations and dependencies among NSDs and VNFs.

description: Recently two studies on Wikimedia editors were performed. One was global
distributing online questionnaires to probability strata selected participants of various Wikimedia
projects in different parts of the world, and the other one was a content analysis of personal pages of
active contributors on Czech Wikipedia. Results show, that most of the contributors are males with
tertiary education, living in cities. The Czech community seems to get older, but content analysis
does not look like to be the best way to research the editor demographic. Rather data analysis with
the consequent inquiries on various language mutations is recommended. But at first work on the
classification of editors by their activity would be necessary.

description: O Índice Mackenzie de Liberdade Econômica Estadual (IMLEE) é um índice de natureza subnacional que tem como finalidade a comparação de jurisdições estaduais do Brasil a fim de fomentar o debate sobre a liberdade econômica e ambiente de negócios no Brasil por meio de elementos objetivos, assim como estimular a adoção de políticas públicas que ampliem a liberdade econômica, melhorem o ambiente de negócios e permitam maior crescimento e prosperidade da economia brasileira e de seus cidadãos. Com base na metodologia do Fraser Institute no Economic Freedom of North America1 , o IMLEE 2023 apontou ligeira melhoria do ambiente de negócios da maioria dos estados brasileiros, ainda sofrendo as consequências da pandemia da COVID-19. O ano base dos dados utilizados é 2021. O que é o IMLEE? É um indicador sintético que mede em que medida as políticas das UF (estados e municípios) e as suas conjunturas específicas foram, em 2021, capazes de apoiar a liberdade econômica - a capacidade dos indivíduos agirem na esfera econômica sem restrições indevidas. É um índice único no Brasil e que ajuda a avaliar as condições de se empreender nos diferentes estados brasileiros e o grau de interferência estatal. O índice varia de zero (menos liberdade) a dez (mais liberdade) e é uma medida relativa de desempenho das unidades federativas. De acordo com estudo publicado sobre o IMLEE, em geral, as unidades federativas que se encontram no grupo de maior nível de liberdade econômica contam com maior PIB per-capita e menor informalidade no mercado de trabalho2 . Resultados do Relatório 2023 A nota média do conjunto das unidades federativas do Brasil subiu para 4,38 ante 4,06 do relatório passado. É um aumento compatível com o ganho de algumas posições que o país obteve no Economic Freedom of the World 2023 (EFW 2023) do Fraser Institute e com o aumento geral das pontuações das jurisdições como consequência da disseminação da vacinação e do começo da retomada das atividades em decorrência da pandemia da COVID-19 e das políticas para lidar com ela. Vale lembrar que o EFW 2023 foi elaborado também com base nos dados de 2023.

description: Poster presented at Royal Society of Chemistry Ultra Large Chemical Libraries Meeting. Abstract: Digital technologies and computational resources are being utilised in scientific research and an increasing rate, however, the vast potential of these resources has yet to be realised. The physical sciences data infrastructure (PSDI) project aims to accelerate research in the physical sciences by providing a data infrastructure that brings together and builds upon the various data systems researchers currently use.
Through PSDI researchers will be able to:
• Find and Access to reference quality data from commercial and open sources
• Combine data from different sources
• Share data, software and models including experimental and simulation data
• Deploy close-to-data computation and containerisation of data and software
• Use AI to explore data
• Learn how to make the results of their research open and FAIR
 The first phase of this project was funded through the EPSRC digital research infrastructure and ran until 31st March 2022. In the pilot work has been undertaken in community engagement and requirements gathering to evaluate the potential of PSDI, explore and evaluate technology options and architecture designs for PSDI, and to work on a variety of case studies to scope out how proposed elements of PSDI could influence cutting edge research. This poster will detail the work undertaken so far as part of this project.
A Geospatial Analysis of Potential Transmission Line Routes in the Pan-Arctic
Creators: name: Jacobs, Nicole

Publisher: name: Zenodo
Year: 2023

description: The Arctic is warming three times faster than the global average, with climate change driving many changes, adding further complexity to the region's unique challenges that call for interdisciplinary, collaborative, innovative, and sustainable solutions. This study will develop a comprehensive geospatial analysis of potential transmission line routes connecting the Pan-Arctic, aimed at enhancing the region's human development, economic growth, influence, and national security. The proposed Pan-Arctic Transmission Line Network (PATLN) has the potential to foster international collaboration, increase resilience, create access to development opportunities, contribute to sustainable energy goals, and overall enhance Arctic capabilities.  We will present our preliminary plan for geospatial analysis that combines multiple data layers to identify potential transmission line corridors, including existing infrastructure, topography, and environmental constraints. The project will integrate ongoing and future economic development activities such as mining and considers transportation infrastructure and community development. We will apply planning-level cost estimation models to support the evaluation of future pathways.  The PATLN project aims to emphasize the advantages and productivity of a connected grid. It brings many potential benefits for communities, such as accessibility to critical infrastructure and community development opportunities, demonstrating the possibility of a unified strategy considering the regional, national, and local levels.  This approach offers the opportunity to engage decision-makers, policy-makers, and the energy industry, around a framework for considering future projects around the Arctic. It supports collaborative, interdisciplinary, planning to develop new pathways toward a resilient Arctic.

description: We investigate the possible structures of numbers (as physical quantities) over which accelerated observers can be modeled in special relativity. We present a general axiomatic theory of accelerated observers which has a model over every real closed field. We also show that, if we would like to model certain accelerated observers, then not every real closed field is suitable, e.g., uniformly accelerated observers cannot be modeled over the field of real algebraic numbers. Consequently, the class of fields over which uniform acceleration can be investigated is not axiomatizable in the language of ordered fields.

description: The Sydney University Stellar Interferometer (SUSI) has two beam combiners, i.e. the Precision Astronomical Visible Observations (PAVO) and the Microarcsecond University of Sydney Companion Astrometry (MUSCA). The primary beam combiner, PAVO, can be operated independently and is typically used to measure properties of binary stars of less than 50 milliarc- sec (mas) separation and the angular diameters of single stars. On the other hand, MUSCA was recently installed and must be used in tandem with the for- mer. It is dedicated for microarcsecond precision narrow-angle astrometry of close binary stars. The performance evaluation and development of the data reduction pipeline for the new setup was assisted by an in-house computer simulation tool developed for this and related purposes. This paper describes the framework of the simulation tool, simulations carried out to evaluate the performance of each beam combiner and the expected astrometric precision of the dual beam combiner setup, both at SUSI and possible future sites.

description: We discuss the effects of diffusion of high energy cosmic rays in turbulent extra-galactic magnetic fields. We find an approximate expression for the low energy suppression of the spectrum of the different mass components (with charge $Z$) in the case in which this suppression happens at energies below $\sim Z$ EeV, so that energy losses are dominated by the adiabatic ones. The low energy suppression appears when cosmic rays from the closest sources take a time comparable to the age of the Universe to reach the Earth. This occurs for energies $E< Z\, {\rm EeV}\,(B/{\rm G})\sqrt{l_c/{\rm Mpc}}(d_s/70\ {\rm Mpc})$ in terms of the magnetic field RMS strength $B$, its coherence length $l_c$ and the typical separation between sources $d_s$. We apply this to scenarios in which the sources produce a mixed composition and have a relatively low maximum rigidity ($E_{max}\sim (2$--$10) Z $ EeV), finding that diffusion has a significant effect on the resulting spectrum, the average mass and on its spread, in particular reducing this last one. For reasonable values of $B$ and $l_c$ these effects can help to reproduce the composition trends observed by the Auger Collaboration for source spectra compatible with Fermi acceleration.

description: We present APEX/P-ArTéMiS 450μm continuum observations of RCW 36 and the adjacent ridge, a high-mass high-column density filamentary structure at the centre of the Vela C molecular cloud. These observations, at higher resolution than Herschel's SPIRE camera, reveal clear fragmentation of the central star-forming ridge. Combined with PACS far-infrared and SPIRE sub-millimetre observations from the Herschel HOBYS project we build a high resolution column density map of the region mapped with P-ArTéMiS. We extract the radial density profile of the Vela C ridge which with a ~ 0.1pc central width is consistent with that measured for low-mass star-forming filaments in the Herschel Gould Belt survey. Direct comparison with Serpens South, of the Gould Belt Aquila complex, reveals many similarities between the two regions. Despite likely different formation mechanisms and histories, the Vela C ridge and Serpens South filament share common characteristics, including their filament central widths.

title: Late Pleistocene chronostratigraphy of infills and incisions based on 3D-modelling of a local watershed sediment sink structure (Borisoglebsk Upland, Central European Russia)

description: 3D-modelling based on a series of geological exposures and cores up to 7 m deep allowed to reveal the structure, stratigraphy and chronology of a local sediment sink on the watershed of one of the Late Saalian glacial uplands at the center of the Russian Plain. This local section representing an infill of a kettle hole was initially occupied by the shallow stagnant water body during the Eemian up to the Late Weichselian, which had periodically dried and transformed into the forested bog. The Late Pleistocene to Holocene transition was associated with most dramatic environmental changes and abrupt fluctuations. Response in the local geomorphodynamics first involved activation of mass movements followed by the gully incision reaching the site by regressive head knickpoint retreat. The observed sediment record provides evidences of at least 4 linear erosion incision-infill cycles. The first incision into the gradually undulating surface composed by lacustrine and colluvial deposits and its infill by stratified colluvial silts occurred not later than 6.5 cal. ka BP. It is fixed by the next incision phase infilled by pedo-sediments of reworked humic, eluvial and sub-eluvial horizons of the upper slope soils enriched by pyrogenic charcoal. The third incision stage can be linked to regressive growth of the main gully head and its branches (ca. 1.4 cal. ka BP) triggered by the onset of cut-and-burn agriculture practices determining conditions favorable for active deposition of agrogenic colluvium. Modern gully incision was preceded at least by another infill phase and occurred between 1941-1968 AD.

Efficient DFT+U calculations of ballistic electron transport: Application to Au monatomic chains with a CO impurity

description: An efficient method for computing the Landauer-Buettiker conductance of an open quantum system within DFT+U is presented. The Hubbard potential is included in electronic structure and transport calculations as a simple renormalization of the non-local pseudopotential coefficients by restricting the integration for the on-site occupations within the cutoff spheres of the pseudopotential. We apply the methodology to the case of an Au monatomic chain in presence of a CO molecule adsorbed on it. We show that the Hubbard U correction removes the spurious magnetization in the pristine Au chain at the equilibrium spacing, as well as the unphysical contribution of d electrons to the conductance, resulting in a single (spin-degenerate) transmission channel and a more realistic conductance of 1 G_0 . We find that the conductance reduction due to CO adsorption is much larger for the atop site than for the bridge site, so that the general picture of electron transport in stretched Au chains given by the local density approximation remains valid at the equilibrium Au-Au spacing within DFT+U.

description: After implementation of the Repository Site Selection Act (StandAG) in 2017, the Federal Company for Radioactive Waste Disposal mbH (BGE mbH), as the German waste-management organization, started the site-selection procedure for a nuclear repository for high-level radioactive waste in Germany. On the way towards the repository site with the best possible safety, the site-selection procedure is required to be a participatory, transparent, learning and self-questioning process based on scientific expertise. With the Sub-areas Interim Report published in 2020, first results were presented, outlining sub-areas with favorable geological conditions in preparation for defining the site regions for surface exploration. The identified 90 sub-areas with favorable geological conditions cover approximately 54% of the area of Germany. Currently, one of the main tasks in the site selection procedure is to conduct the representative preliminary safety assessments for each sub-area. Apart from the technical descriptions of the repository system, the geoscientific characterization and interpretation (Geosynthesis) of the host rock, the overburden and the geological processes serve as a basis for the safety assessment. The main character of the Geosynthesis is therefore to compile all geoscientific information, relevant to the safety of a repository. Additionally, we describe how the Geosynthesis could be used to identify potentially suitable areas within large sub-areas. These areas with the most favourable geological conditions will then be evaluated in more detail during the representative preliminary safety assessments.

description: The shortage of face masks and the lack of antipathogenic functions has been significant since the recent pandemic's inception. Moreover, the disposal of an enormous number of contaminated face masks not only carries a significant environmental impact but also escalates the risk of cross-contamination. This study proposes a strategy to upgrade available surgical masks into antibacterial masks with enhanced particle and bacterial filtration. Plasmonic nanoparticles can provide photodynamic and photothermal functionalities for surgical masks. For this purpose, gold nanorods act as on-demand agents to eliminate pathogens on the surface of the masks upon near-infrared light irradiation. Additionally, the modified masks are furnished with polymer electrospun nanofibrous layers. These electrospun layers can enhance the particle and bacterial filtration efficiency, not at the cost of the pressure drop of the mask. Consequently, fabricating these prototype masks could be a practical approach to upgrading the available masks to alleviate the environmental toll of disposable face masks.

Scaling Laws for Planetary Dynamos
Creators: name: Davidson, P. A.
Publisher: name: arXiv
Year: 2013
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: We propose new scaling laws for the properties of planetary dynamos. In particular, the Rossby number, the magnetic Reynolds number, the ratio of magnetic to kinetic energy, the Ohmic dissipation timescale and the characteristic aspect ratio of the columnar convection cells are all predicted to be power-law functions of two observable quantities: the magnetic dipole moment and the planetary rotation rate. The resulting scaling laws constitute a somewhat modified version of the scalings proposed in Christensen & Aubert (2006) and Christensen (2010). The main difference is that, in view of the small value of the Rossby number in planetary cores, we insist that the nonlinear inertial term, (u.grad)u, is negligible. This changes the exponents in the power-laws which relate the various properties of the fluid dynamo to the planetary dipole moment and rotation rate. Our scaling laws are consistent with the available numerical evidence.

description: Consider two independent Goldstein-Kac telegraph processes $X_1(t)$ and $X_2(t)$ on the real line $\Bbb R$. The processes $X_k(t), \; k=1,2,$ are performed by stochastic motions at finite constant velocities $c_1>0, \; c_2>0,$ that start at the initial time instant $t=0$ from the origin of the real line $\Bbb R$ and are controlled by two independent homogeneous Poisson processes of rates $λ_1>0, \; λ_2>0$, respectively. Closed-form expression for the probability distribution function of the Euclidean distance $$ρ(t) = |X_1(t) - X_2(t) |, \qquad t>0,$$ between these processes at arbitrary time instant $t>0$, is obtained. Some numerical results are presented.
