History and evolution of the Sagittarius galaxy
Creators: name: Vitali
Publisher: name: Zenodo
Year: 2023

description: The importance of chemical characterization for studying the history of the Milky Way (MW) and its accretion events is well established. However, challenges remain, especially at lower metallicities. N-capture elements carry insightful information concerning chemical evolution, but their distribution especially in very MW metal-poor stars shows a large dispersion in chemical space that chemical evolution models are still not able to explain. One of the possibilities may be the diversity of accreted satellites that contributed to the actual MW stellar composition. In this scenario, I am investigate the role of the interaction between the Sagittarius dwarf spheroidal galaxy (dSph) and the MW in its structure and chemical evolution. For this purpose I observed a sample of around 100 Sagittarius stars (-2 < [Fe/H] < -0.5) with FLAMES to derive precise chemical abundances, specifically the pure r-process element Eu and the neutron-capture first and second peak s-process elements (Y, Zr, Ba, La). These analysis can shed light on the star formation history of Sagittarius and on its contribution to the MW build-up. Moreover, the determination of the [α/Fe]-knee position, still not well characterized in the literature can help us to gain information about the early evolution and the initial mass function of this system. These studies can be keys results for tracing the evolution of our Galaxy and of other system, e.g dwarf satellites galaxies, with which it interacts.

description: We report on the spatially resolved full amplitude and phase characterization of mid-infrared high intensity laser pulses generated in a three stage OPA. We use a spatially-encoded arrangement (SEA-)SPIDER with spectral filters for ancilla generation for spatially resolved characterization. Using five interchangeable filter sets we are able to characterize pulses from 1 to 2μm with one single device with minimal adjustments.

description: We consider a model of inflation which has recently been proposed in the literature and where inflation is induced by corrections to the energy density coming from the non-commutativity of spacetime. We show that the very rapid inflationary expansion typical of this model is responsible for a burst of particle production which ends inflation and leads to a radiation-dominated phase. We analytically estimate the energy density of these particles and we confront the results with more precise numerical calculations. We estimate the number of inflationary e-folds before the back-reaction of the radiation energy density overcomes the non-commutative effects and terminate inflation naturally.

Electron transfer through a single barrier inside a molecule: from strong to weak coupling

description: In all theoretical treatments of electron transport through single molecules between two metal electrodes, a clear distinction has to be made between a coherent transport regime with a strong coupling throughout the junction and a Coulomb blockade regime in which the molecule is only weakly coupled to both leads. The former case where the tunnelling barrier is considered to be delocalized across the system can be well described with common mean-field techniques based on density functional theory (DFT), while the latter case with its two distinct barriers localized at the interfaces usually requires a multideterminant description. There is a third scenario with just one barrier localized inside the molecule which we investigate here using a variety of quantum-chemical methods by studying partial charge shifts in biphenyl radical ions induced by an electric field at different angles to modulate the coupling and thereby the barrier within the $π$-system. We find steps rounded off at the edges in the charge versus field curves for weak and intermediate coupling, whose accurate description requires a correct treatment of both exchange and dynamical correlation effects is essential. We establish that DFT standard functionals fail to reproduce this feature, while a long range corrected hybrid functional fares much better, which makes it a reasonable choice for a proper DFT-based transport description of such single barrier systems

Spin decoherence due to Fluctuating Fields

description: The dynamics of a spin in the presence of a deterministic and a fluctuating magnetic field is solved for analytically to obtain the averaged value of the spin as a function of time for various kinds of fluctuations (noise). Specifically, analytic results are obtained for the time dependence of the expectation value of the spin, averaged over fluctuations, for Gaussian white noise and Guassian colored noise, as well as non-Gaussian telegraph noise. Fluctuations cause the decay of the average spin vector (decoherence). For noise with finite temporal correlation time, a deterministic component of the field can suppress decoherence of the spin component along the field. Hence, decoherence can be manipulated by controlling the deterministic magnetic field. A simple universal physical picture emerges which explains the mechanism of the suppression of the decay.

description: The universal Kummer threefold is a 9-dimensional variety that represents the total space of the 6-dimensional family of Kummer threefolds in 7-dimensional projective space. We compute defining polynomials for three versions of this family, over the Satake hypersurface, over the Göpel variety, and over the reflection representation of type E7. We develop classical themes such as theta functions and Coble's quartic hypersurface using current tools from combinatorics, geometry, and commutative algebra. Symbolic and numerical computations for genus 3 moduli spaces appear alongside toric and tropical methods.

description: The contribution of the R-parity violating minimal supersymmetric standard model to the neutron beta decay at the one-loop level is investigated. It is found that the baryon number and R-parity violating interactions contribute to the D correlation through one-loop corrections, while the tree level prediction is vanishing. The Fierz interference term is also investigated at the one-loop level by considering the lepton number and R-parity violating interactions. We show that future experimental progress can provide us with better constraints on some of the combinations of R-parity violating couplings.

Inverse scattering of dispersive stratified structures

description: We consider the inverse scattering problem of retrieving the structural parameters of a stratified medium consisting of dispersive materials, given knowledge of the complex reflection coefficient in a finite frequency range. It is shown that the inverse scattering problem does not have a unique solution in general. When the dispersion is sufficiently small, such that the time-domain Fresnel reflections have durations less than the round-trip time in the layers, the solution is unique and can be found by layer peeling. Numerical examples with dispersive and lossy media are given, demonstrating the usefulness of the method for e.g. THz technology.

description: Using radio sources from the Faint Images of the Radio Sky at Twenty-cm (FIRST) survey, and optical counterparts in the Sloan Digital Sky Survey (SDSS), we have identified a large number of galaxy clusters. The radio sources within these clusters are driven by active galactic nuclei, and our cluster samples include clusters with bent, and straight, double-lobed radio sources. We also included a single-radio-component comparison sample. We examine these galaxy clusters for evidence of optical substructure, testing the possibility that bent double-lobed radio sources are formed as a result of large-scale cluster mergers. We use a suite of substructure analysis tools to determine the location and extent of substructure visible in the optical distribution of cluster galaxies, and compare the rates of substructure in clusters with different types of radio sources. We found no preference for significant substructure in clusters hosting bent double-lobed radio sources compared to those with other types of radio sources.

description: The total number of true, likely and possible planetary nebulae (PN) now known in the Milky Way is about 3000, approximately twice the number known a decade ago. The new discoveries are a legacy of the recent availability of wide-field, narrowband imaging surveys, primarily in the light of H-alpha. The two most important are the AAO/UKST SuperCOSMOS H-alpha survey - SHS and the Isaac Newton photometric H-alpha survey - IPHAS, which are responsible for most of the new discoveries. A serious problem with previous PN catalogues is that several different kinds of astrophysical objects are able to mimic PN in some of their observed properties leading to significant contamination. These objects include H II regions and Stromgren zones around young O/B stars, reflection nebulae, Wolf-Rayet ejecta, supernova remnants, Herbig-Haro objects, young stellar objects, B[e] stars, symbiotic stars and outflows, late-type stars, cataclysmic variables, low redshift emission-line galaxies, and even image/detector flaws. PN catalogues such as the Macquarie/AAO/Strasbourg H-alpha Planetary Nebula catalogue (MASH) have been carefully vetted to remove these mimics using the wealth of new wide-field multi-wavelength data and our 100% follow-up spectroscopy to produce a compilation of new PN discoveries of high purity. During this process significant numbers of PN mimics have been identified. The aim of this project is to compile these MASH rejects into a catalogue of Miscellaneous Emission Nebulae (MEN) and to highlight the most unusual and interesting examples. A new global analysis of these MEN objects is underway before publishing the MEN catalogue online categorizing objects by type together with their spectra and multi-wavelength images.

description: This report demonstrates the most spatially-coherent electron source ever reported. A coherence angle of 14.3 +/- 0.5 degrees was measured, indicating a virtual source size of 1.7 +/-0.6 Angstrom using an extraction voltage of 89.5 V. The nanotips under study were crafted using a spatially-confined, field-assisted nitrogen etch which removes material from the periphery of the tip apex resulting in a sharp, tungsten-nitride stabilized, high-aspect ratio source. The coherence properties are deduced from holographic measurements in a low-energy electron point source microscope with a carbon nanotube bundle as sample. Using the virtual source size and emission current the brightness normalized to 100 kV is found to be 7.9x10^8 A/sr cm^2.

description: Popular cosmological scenarios predict that galaxies form hierarchically from the merger of many progenitors, each with their own unique star formation history (SFH). We use a sophisticated approach to constrain the SFHs of 4517 blue (presumably star-forming) galaxies with spectroscopic redshifts in the range 0.2 < z < 1.4 from the All-Wavelength Extended Groth Strip International Survey (AEGIS). This consists in the Bayesian analysis of the observed galaxy spectral energy distributions with a comprehensive library of synthetic spectra assembled using realistic, hierarchical star formation and chemical enrichment histories from cosmological simulations. We constrain the SFH of each galaxy in our sample by comparing the observed fluxes in the B, R, I and Ks bands and rest-frame optical emission-line luminosities with those of one million model spectral energy distributions. We explore the dependence of the resulting SFHs on galaxy stellar mass and redshift. We find that the average SFHs of high-mass galaxies rise and fall in a roughly symmetric bell-shaped manner, while those of low-mass galaxies rise progressively in time, consistent with the typically stronger activity of star formation in low-mass compared to high-mass galaxies. For galaxies of all masses, the star formation activity rises more rapidly at high than at low redshift. These findings imply that the standard approximation of exponentially declining SFHs widely used to interpret observed galaxy spectral energy distributions may not be appropriate to constrain the physical parameters of star-forming galaxies at intermediate redshifts.

A physical model for the 0 < z < 8 redshift evolution of the galaxy UV luminosity and stellar mass functions

description: We present a model to understand the redshift evolution of the UV luminosity and stellar mass functions of Lyman Break Galaxies. Our approach is based on the assumption that the luminosity and stellar mass of a galaxy is related to its dark matter halo assembly and gas infall rate. Specifically, galaxies experience a burst of star formation at the halo assembly time, followed by a constant star formation rate, representing a secular star formation activity sustained by steady gas accretion. Star formation from steady gas accretion is the dominant contribution to the galaxy UV luminosity at all redshifts. The model is calibrated by constructing a galaxy luminosity versus halo mass relation at $z=4$ via abundance matching. After this luminosity calibration, the model naturally fits the $z=4$ stellar mass function, and correctly predicts the evolution of both luminosity and stellar mass functions from $z=0$ to $z=8$. While the details of star formation efficiency and feedback are hidden within our calibrated luminosity versus halo mass relation, our study highlights that the primary driver of galaxy evolution across cosmic time is the build-up of dark matter halos, without the need to invoke a redshift dependent efficiency in converting gas into stars.

In particular, we identify conditions at which the first moiré miniband is separated from the rest of the spectrum by either one or a group of three isolated mini Dirac points and is not obscured by dispersion surfaces coming from other minibands. In such cases the Hall coefficient exhibits two distinct alternations of its sign as a function of charge carrier density.

description: We attempt to determine the nature of the high energy emission of the radio galaxy 3C 111, by distinguishing between the effects of the thermal and non-thermal processes. We study the X-ray spectrum of 3C 111 between 0.4 keV and 200 keV, and its spectral energy distribution, using data from the Suzaku satellite combined with INTEGRAL, Swift/BAT data, and Fermi/LAT data. We then model the overall spectral energy distribution including radio and infrared data. The combined Suzaku, Swift and INTEGRAL data are represented by an absorbed exponentially cut-off power-law with reflection from neutral material with a photon index Gamma = 1.68+-0.03, a high-energy cut-off Ecut = 227+143-67 keV, a reflection component with R = 0.7+-0.3 and a Gaussian component to account for the iron emission-line at 6.4 keV with an equivalent width of EW = 85+-11 eV. The X-ray spectrum appears dominated by thermal, Seyfert-like processes, but there are also indications of non-thermal processes. The radio to gamma-ray spectral energy distribution can be fit with a single-zone synchrotron-self Compton model, with no need for an additional thermal component. We suggest a hybrid scenario to explain the broad-band emission, including a thermal component (iron line, reflection) that dominates in the X-ray regime and a non-thermal one to explain the spectral energy distribution.

Large scale distribution of arrival directions of cosmic rays detected above $10^{18}$ eV at the Pierre Auger Observatory

description: A thorough search for large scale anisotropies in the distribution of arrival directions of cosmic rays detected above $10^{18}$ eV at the Pierre Auger Observatory is presented. This search is performed as a function of both declination and right ascension in several energy ranges above $10^{18}$ eV, and reported in terms of dipolar and quadrupolar coefficients. Within the systematic uncertainties, no significant deviation from isotropy is revealed. Assuming that any cosmic ray anisotropy is dominated by dipole and quadrupole moments in this energy range, upper limits on their amplitudes are derived. These upper limits allow us to challenge an origin of cosmic rays above $10^{18}$ eV from stationary galactic sources densely distributed in the galactic disk and emitting predominantly light particles in all directions.

description: A fundamental problem in quantum information is to explore what kind of quantum correlations is responsible for successful completion of a quantum information procedure. Here we study the roles of entanglement, discord, and dissonance needed for optimal quantum state discrimination when the latter is assisted with an auxiliary system. In such process, we present a more general joint unitary transformation than the existing results. The quantum entanglement between a principal qubit and an ancilla is found to be completely unnecessary, as it can be set to zero in the arbitrary case by adjusting the parameters in the general unitary without affecting the success probability. This result also shows that it is quantum dissonance that plays as a key role in assisted optimal state discrimination and not quantum entanglement. A necessary criterion for the necessity of quantum dissonance based on the linear entropy is also presented.

ERICC Helpdesk Report _ Reflective Review of Sudans Secondary School Examinations
Creators: name: ERICC Consortium
Publisher: name: figshare

Subjects: classificationCode: 390201
subject: Education policy

description: War erupted between the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF) on 15 April 2023, and the education landscape in Sudan has changed substantially since the outbreak of the war. Current figures estimate a total of 17 million out of 19 million school aged children remain out of school as of December 2024, with over 3.8 million children displaced internally or cross-border, and 18% of schools reportedly used as shelters for the displaced population (Education Cluster, 2024).On 27 October 2024 the Sudanese Federal Ministry of Education (FMoE) formally announced the decision to administer secondary school examinations for the 2022/23 cohort, with intent to hold examinations announced as early as July 2024.
Members of the Local Education Group and Education
Cluster encouraged the Federal Ministry of Education to pursue alternative options; however, the FMoE ultimately chose to proceed with examinations in December 2024, offering optional deferral to later cycles for those students unable to take the examinations in December. As a result, members of the international and Sudanese community coordinated a response to address the educational and
protection needs of students sitting for the December 2024 examination cycle.
ERICC Helpdesk has been requested to conduct a rapid review of events leading up to and during the administration of examinations, an analysis of the coordinated response during the examinations themselves, and the identification of lessons learnt to inform the approach of the education
community to future examination cycles.

description: We report the discovery of a planetary system from observation of the high-magnification microlensing event OGLE-2012-BLG-0026. The lensing light curve exhibits a complex central perturbation with multiple features. We find that the perturbation was produced by two planets located near the Einstein ring of the planet host star. We identify 4 possible solutions resulting from the well-known close/wide degeneracy. By measuring both the lens parallax and the Einstein radius, we estimate the physical parameters of the planetary system. According to the best-fit model, the two planet masses are ~0.11 M_Jupiter and 0.68 M_Jupiter and they are orbiting a G-type main sequence star with a mass ~0.82 M_Sun. The projected separations of the individual planets are beyond the snow line in all four solutions, being ~3.8 AU and 4.6 AU in the best-fit solution. The deprojected separations are both individually larger and possibly reversed in order. This is the second multi-planet system with both planets beyond the snow line discovered by microlensing. This is the only such a system (other than the Solar System) with measured planet masses without sin(i) degeneracy. The planetary system is located at a distance 4.1 kpc from the Earth toward the Galactic center. It is very likely that extra light from stars other than the lensed star comes from the lens itself. If this is correct, it will be possible to obtain detailed information about the planet-host star from follow-up observation.

Our Families
Creators: name: Pinto, Marta Delgado
Publisher: name: Journal of Science and Technology of the Arts
Year: 2023

description: Yasujirô Ozu’s Tōkyō Monogatari (1953) is often considered as one of the best movies ever made. Within Portuguese cinema, it inspired João Botelho to make his 1986 piece Um Adeus Português. This audio-visual essay attempts to explore the films’ similarities and expose the hearts of both their stories, which are, at their core, simple and moving depictions of families.

'Our Families' by Marta Pinto: An Audiovisual Essay on 'A Portuguese Farewell' and 'Tokyo Story'
Creators: name: Soares, Ana Isabel
Publisher: name: Journal of Science and Technology of the Arts
Year: 2023

description: Marta Pinto’s audiovisual essay on Tokyo Story (1953) and A Portuguese Farewell (1985), two central works in the filmography of Yasujirō Ozu and João Botelho, evinces the influence the 1953 film had on the Portuguese director. However, more interestingly the essay shows the extent to which both works differ in their approach to war. Not only are the plots in the two films presented in distinct perspectives but their formal modes are dissimilar despite the affiliation assumed by João Botelho. A reading of those differences, underlined by formal aspects of the visual essay, considers also the role of spectators in the complex relationship between cinema and the recent history of a nation.

description: We examine the red fraction of central and satellite galaxies in the large zCOSMOS group catalog out to z ~ 0.8 correcting for both the incompleteness in stellar mass and for the less than perfect purities of the central and satellite samples. We show that, at all masses and at all redshifts, the fraction of satellite galaxies that have been quenched, i.e., are red, is systematically higher than that of centrals, as seen locally in the Sloan Digital Sky Survey (SDSS). The satellite quenching efficiency, which is the probability that a satellite is quenched because it is a satellite rather than a central, is, as locally, independent of stellar mass. Furthermore, the average value is about 0.5, which is also very similar to that seen in the SDSS. We also construct the mass functions of blue and red centrals and satellites and show that these broadly follow the predictions of the Peng et al. analysis of the SDSS groups. Together, these results indicate that the effect of the group environment in quenching satellite galaxies was very similar when the universe was about a half its present age, as it is today.

Change in Meanings in Psychotherapy: A Commentary on the Essay 'Concetualization of Change'
Creators: name: Gonçalves, Miguel
Publisher: name: Journal of Science and Technology of the Arts
Year: 2023

description: This paper analyzes the audiovisual essay Conceptualization of Change from the perspective of psychotherapy. Psychotherapy aims to transform lives and alleviate people’s suffering, making it a natural setting to observe and study how individuals undergo change (or remain unchanged). The essay explores the concept of innovative moments, which represent exceptions to the problems that led clients to seek psychotherapy. Defining an innovative moment requires identifying a problematic pattern beforehand, as these moments are defined as deviations from the established pattern. This identification process is not straightforward in psychotherapy and becomes even more challenging in social and political contexts due to the involvement of political and ethical considerations. The paper suggests that increasing complexity and fostering dialogue serve as overarching criteria for defining innovative moments in the wider socio-political contexts.

Storytelling For A Non-Foreclosed World: A Conversation With Manthia Diawara
Creators: name: Baer, Ulrich C.
Publisher: name: Journal of Science and Technology of the Arts
Year: 2023

description: Ulrich Baer and Manthia Diawara delve into an exploration of art, culture, and identity, throughout Diawara's body of work. They discuss the profound influence of Édouard Glissant on Diawara's work and thought. The conversation opens with an exploration of the possibility of a non-foreclosed world that would embrace Glissant’s poécepts of créolisation and identité-relation, emphasizing the importance of fluid and complex identities. The subsequent segment is focused on the possibility of a shared worldly sensibility paired with local action, and the implications of political engagement in art practices. In the last part, the historical, cultural and political importance of African American narratives is discussed, along with the characterization of storytelling as a form of rationality. Throughout the conversation, Baer and Diawara demonstrate their shared belief in the transformative potential of art and scholarship, and in the importance of engaging in meaningful discussions on cultural identity, representation, and liberation.

A Study on the Expansion of the Audiences’ Aesthetic Experience by Applying the Punctum in Interactive Installations
Creators: name: Oh, Je-Ho
Publisher: name: Journal of Science and Technology of the Arts
Year: 2023

description: This study suggests ways to expand aesthetic experience through Roland Barthes’ concept the punctum found while creating the interactive artwork deBallution based on the audiences’ throwing activities. Roland Barthes defined the punctum in his book Camera Lucida as applying not a studium or thematic element but the elements of personal experience and memory to an aesthetic element in the photograph. This study develops a methodology for applying the punctum to interactive artwork based on the five symbolic elements of the punctum mentioned by Roland Barthes: String, Speck, Cut, Little hole, and Cast of the dice. It also confirms whether audiences actually experienced the five elements of the punctum and the studium through user testing conducted after making a new test version of the interactive artwork deBallution: Randomized Trip.
