description: Η παρούσα εργασία αποτελεί μια προσπάθεια παρουσίασης των Πράσινων Σημείων (ΠΣ), των χαρακτηριστικών τους, των ωφελειών από τη λειτουργία τους και την ανάπτυξη της μεθοδολογίας, χωροθέτησής τους, όπως αυτή καθορίζεται από την ισχύουσα νομοθεσία, καθώς από την πετυχημένη χωροθέτηση εξαρτάται σε μεγάλο βαθμό η επιτυχία ή όχι της συνολικής λειτουργίας τους. Αναφορικά με τη δομή και το περιεχόμενο της εργασίας, αρχικά, μετά από την εισαγωγή στα ζητήματα διαχείρισης αποβλήτων, θα γίνει αναφορά στον όρο Πράσινο Σημείο, στα βασικά στοιχεία και χαρακτηριστικά της εγκατάστασης και στη συνέχεια, στο κυρίως μέρος της εργασίας, θα παρουσιαστεί η ισχύουσα νομοθεσία, οι προδιαγραφές, τα κριτήρια και η μεθοδολογία για την εγκατάσταση Πράσινων Σημείων. Επίσης, θα γίνει διερεύνηση των οικονομικών και περιβαλλοντικών ωφελειών που ενδέχεται να προκύψουν από την εγκατάσταση τους, όπως εξοικονόμηση πρώτων υλών, ενέργειας, νερού, περιορισμός των δαπανών, μείωση των αερίων που συμβάλουν στη κλιματική αλλαγή, διαμόρφωση νέων μοντέλων κοινωνικής συμπεριφοράς. Τέλος, καθώς τα Πράσινα Σημεία αποτελούν πλέον σε τοπικό επίπεδο βασικό στοιχείο του συστήματος διαχείρισης αποβλήτων και κάθε Δήμος υποχρεούται να λειτουργεί τουλάχιστον ένα Πράσινο Σημείο, η εργασία περιλαμβάνει την εφαρμογή του θεωρητικού πλαισίου που διέπει την εγκατάσταση πράσινων σημείων στο δήμο Θέρμης, με σκοπό τη διαμόρφωση πρότασης χωροθέτησης Πράσινου Σημείου στον εν λόγω δήμο και ειδικότερα στα όρια της δημοτικής ενότητας Θέρμης
description: The present thesis is an attempt to present the green points, their characteristics, the benefits of their operation as well as the development of the methodology, as defined by the current legislation, their location, as their overall operation depends greatly on their successful location. Regarding to the structure and content of the work, after the introduction on waste management issues, the term Green Point will first be referred to, the basic elements and characteristics of the installation and then, in the main part of the work, the applicable legislation, specifications, criteria and the methodology for installing green spots will be presented. This thesis will also explore the economic, environmental and social benefits resulting from their installation, such as saving on raw materials, energy, water, reducing costs, reducing gases that contribute to climate change, developing new models of social behavior. Finally, as Green Points are now locally an essential element of the waste management system and each Municipality must operate at least one Green Point, the present thesis will try to apply the theoretical framework in practice, in order to install green points in the municipality of Thermi, with the intention to find the optimal location for a green spot in the municipal unit of Thermi

description: Η παρούσα εργασία ασχολείται με την Εκπαίδευση στα Ανθρώπινα Δικαιώματα, ως όψη της Περιβαλλοντικής Εκπαίδευσης και της Εκπαίδευσης για την Αειφορία. Πρόκειται για μια έρευνα δράση, κατά την οποία εφαρμόστηκε ένα προγράμματος θεατροπαιδαγωγικής σε παιδιά ενός ελληνικού δημόσιου νηπιαγωγείου της πόλης της Θεσσαλονίκης. Κεντρικό θέμα της παρέμβασης είναι τα δικαιώματα. Το μεγαλύτερο μέρος του προγράμματος πραγματεύεται τα δικαιώματα του παιδιού, ενώ επιχειρείται μια πρωτόλεια αναφορά στα δικαιώματα των ζώων και στην αυταξία της φύσης. Τα ερευνητικά ερωτήματα αφορούν την δυνατότητα εφαρμογής σε παιδιά ηλικίας νηπιαγωγείου ενός προγράμματος με κεντρικό θέμα τα δικαιώματα, αν η θεατροπαιδαγωγική μπορεί να συμβάλλει σε αυτό και με ποιον τρόπο. Τα δεδομένα της έρευνας συλλέχθηκαν με συνεντεύξεις των παιδιών (pre, post) και έτυχαν επεξεργασίας μέσω της θεματικής ανάλυσης (ποιοτική ανάλυση). Η παρούσα έρευνα καταλήγει πως είναι δυνατή η πρώτη προσέγγιση των δικαιωμάτων από τα παιδιά του νηπιαγωγείου. Σε αυτό φαίνεται να συμβάλλει η θεατροπαιδαγωγική μέσω συνθηκών ευνοϊκών για την εκπαίδευση στα ανθρώπινα δικαιώματα, όπως η καλλιέργεια ενσυναίσθησης
description: The present work deals with the Human Rights Education from an Environmental and Sustainability Education perspective. An education-drama activity was applied involving students of a public kindergarten in Thessaloniki, Greece. Human rights is the main subject of the activity. The program mainly concerns children’s rights while we also refer on animal’s rights and natural environment’s value. The research questions concern a) the possibility of applying a program that involves rights as the main subject on kindergarten students and b) whether and how drama education can contribute on such program. The research data were collected by interviewing students and were processed using qualitative analysis. Our analysis indicates that a preliminary approach of human rights by pre-school students is feasible and that drama education can contribute on that by establishing conducive circumstances for human rights education

description: Two ocean models are considered for geophysical flow simulations: the multi-layer shallow water equations and the multi-layer primitive equations. For the former, we investigate the parallel performance of exponential time differencing (ETD) methods, including exponential Rosenbrock-Euler, ETD2wave, and B-ETD2wave. For the latter, we take advantage of the splitting of barotropic and baroclinic modes and propose a new two-level method in which an ETD method is applied to solve the fast barotropic mode. These methods could improve the computational efficiency of numerical simulations because ETD methods allow for much larger time step sizes than traditional explicit time-stepping techniques that are commonly used in existing computational ocean models. Several standard benchmark tests for ocean modeling are performed and comparison of the numerical results demonstrate a great potential of applying the parallel ETD methods for simulating real-world geophysical flows.

description: We investigate the relative importance of starbursts and AGN in nuclear activities of ultra-luminous infrared galaxies (ULIRGs) based on chemodynamical simulations combined with spectrophotometric synthesis codes. We numerically investigate both the gas accretion rates (m_acc) onto super massive black holes (SMBHs) and the star formation rates (m_sf) in ULIRGs formed by gas-rich galaxy mergers and thereby discuss what powers ULIRGs. Our principal results, which can be tested against observations, are as follows. (1) ULIRGs powered by AGN can be formed by major merging between luminous, gas-rich disk galaxies with prominent bulges containing SMBHs, owing to the efficient gas fuelling m_acc > 1 M_sun/yr of the SMBH. AGN in these ULIRGs can be surrounded by compact poststarburst stellar populations (e.g., A-type stars). (2) ULIRGs powered by starbursts with m_sf ~ 100 M_sun/yr can be formed by merging between gas-rich disk galaxies with small bulges having the bulge-to-disk-ratio (f_b) as small as 0.1. (3) The relative importance of starbursts and AGN can depend on physical properties of merger progenitor disks, such as f_b, gas mass fraction, and total masses. For example, more massive galaxy mergers are more likely to become AGN-dominated ULIRGs. (4) For most models, major mergers can become ULIRGs, powered either by starbursts or by AGN, only when the two bulges finally merge. Interacting disk galaxies can become ULIRGs with well separated two cores (> 20kpc) at their pericenter when they are very massive and have small bulges. (5) Irrespective of the choice of model, interacting/merging galaxies show the highest accretion rates onto the central SMBHs, and the resultant rapid growth of the SMBHs occur when their star formation rates are very high.

Landscape of Little Hierarchy

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We investigate the little hierarchy between Z boson mass and the SUSY breaking scale in the context of landscape of electroweak symmetry breaking vacua. We consider the radiative symmetry breaking and found that the scale where the electroweak symmetry breaking conditions are satisfied and the average stop mass scale is preferred to be very close to each other in spite of the fact that their origins depend on different parameters of the model. If the electroweak symmetry breaking scale is fixed at about 1 TeV by the supersymmetry model parameters then the little hierarchy seems to be preferred among the electroweak symmetry breaking vacua. We characterize the little hierarchy by a probability function and the mSUGRA model is used as an example to show the 90% and 95% probability contours in the experimentally allowed region. We also investigate the size of the Higgsino mass by considering the distribution of electroweak symmetry breaking scale.

Cardiac Cousins? The Surprising Connection between Takotsubo and Oshtoran Syndrome.

Year: 2024

description: The hypothesis that Takotsubo (Broken-Heart) Syndrome and Oshtoran Syndrome share overlapping pathomechanisms driven by catecholamines opens new avenues for research and treatment. While Takotsubo is typically self-limiting, the chronicity of Oshtoran Syndrome, potentially due to NTBI and persistent elevated catecholaminergic levels, requires a different therapeutic approach. By leveraging insights from the treatment of Oshtoran Syndrome, it may be possible to improve outcomes for patients with chronic or recurrent forms of Takotsubo. Future research should aim to elucidate the role of NTBI in cardiac dysfunction and explore novel interventions targeting both autonomic regulation and oxidative stress.

Self-Dual Non-Abelian Vector Multiplet in Three Dimensions

description: We present an N=1 supersymmetric non-Abelian compensator formulation for a vector multiplet in three-dimensions. Our total field content is the off-shell vector multiplet (A_μ^I, λ^I) with the off-shell scalar multiplet (ϕ^I, χ^I; F^I) both in the adjoint representation of an arbitrary non-Abelian gauge group. This system is reduced to a supersymmetric sigma-model on a group manifold, in the zero-coupling limit. Based on this result, we formulate a 'self-dual' non-Abelian vector multiplet in three-dimensions. By an appropriate identification of parameters, the mass of the self-dual vector multiplet is quantized. Additionally, we also show that the self-dual non-Abelian vector multiplet can be coupled to supersymmetric Dirac-Born-Infeld action. These results are further reformulated in superspace to get a clear overall picture.

description: We compute the contributions to continuum photon pair production at hadron colliders from processes initiated by gluon-gluon and gluon-quark scattering into two photons through a four-leg virtual quark loop. Complete two-loop cross sections in perturbative quantum chromodynamics are combined with contributions from soft parton radiation resummed to all orders in the strong coupling strength. The structure of the resummed cross section is examined in detail, including a new type of unintegrated parton distribution function affecting azimuthal angle distributions of photons in the pair's rest frame. As a result of this analysis, we predict diphoton transverse momentum distributions in gluon-gluon scattering in wide ranges of kinematic parameters at the Fermilab Tevatron collider and the CERN Large Hadron Collider.

description: The excited-state structure of atomic nuclei can modify nuclear processes in stellar environments. In this work, we study the influence of nuclear excitations on Urca cooling (repeated back-and-forth beta decay and electron capture in a pair of nuclear isotopes) in the crust and ocean of neutron stars. We provide for the first time an expression for Urca process neutrino luminosity which accounts for excited states of both members of an Urca pair. We use our new formula with state-of-the-art nuclear structure inputs to compute neutrino luminosities of candidate Urca cooling pairs. Our nuclear inputs consist of the latest experimental data supplemented with calculations using the projected shell model. We show that, in contrast with previous results that only consider the ground states of both nuclei in the pair, our calculated neutrino luminosities for different Urca pairs vary sensitively with the environment temperature and can be radically different from those obtained in the one transition approximation.

Για τον σκοπό αυτό, η εργασία αυτή διαρθρώθηκε σε δύο επιμέρους κεφάλαια. Στο πρώτο κεφάλαιο γίνεται μία συστηματική ανάλυση του εγκλήματος της παράνομης μεταφοράς μεταναστών. Η έρευνα εκκινεί από την παρουσίαση όλων των απόψεων που διατυπώθηκαν διαχρονικά σχετικά με το έννομο αγαθό που προστατεύεται στη συγκεκριμένη ποινική διάταξη και στη συνέχεια εξετάζονται αναλυτικά τα στοιχεία της νομοτυπικής μορφής του εγκλήματος των μεταφορέων, με αυτοτελείς αναφορές στην αντικειμενική και υποκειμενική υπόσταση του εγκλήματος, καθώς επίσης και στο κυρωτικό τμήμα της διάταξης, ούτως ώστε να καθίσταται σαφής η ανάδειξη όλων των προβληματικών περιοχών γύρω από την ερμηνεία και την εφαρμογή της. Στο δεύτερο κεφάλαιο της έρευνας εξετάζονται ζητήματα απόπειρας και συμμετοχής στο συγκεκριμένο έγκλημα, ενώ γίνεται μια συνοπτική αναφορά και στη θεματική της συρροής του εν λόγω εγκλήματος με άλλες εγκληματικές πράξεις. Η έρευνα ολοκληρώνεται με την ανασκόπηση των κρισιμότερων προβληματικών ζητημάτων που ανέκυψαν κατά την οριοθέτηση του εγκλήματος των μεταφορέων καθώς και με τη διατύπωση μερικών σκέψεων προς περαιτέρω προβληματισμό σχετικά με την εφαρμογή της διάταξης όπως ισχύει σήμερα.
description: The aim of the present thesis is the study of the carriers’ criminal liability, as delineated in the article 30 paragraph 1 of the Greek Immigration Code (Law 4251/2014). For this purpose, this study shall be structured around two individual chapters. In the first one, the illegal transfer of immigrants as a criminal offence is systematically analysed. The research originates from an introduction into all the academic standpoints stated in accordance with the legal good that is protected through this specific criminal provision and, as it progresses, it focuses οn the distinct elements that classify the act as a criminal offence, such as the actus reus and the mens rea, as well as the sanction part of the article. Thus, the main problematic areas around the legal interpretation and application of the provision are enlightened. In the second and final chapter of the research, aspects of the crime attempt and the participation in the crime are scrutinized, while an overview concerning the issue of the appearing conjunction of the crime with other criminal offences is also provided. The study comes to a conclusion by reviewing the most crucial and challenging matters arised through the delineation of the transporters’ criminal act and, subsequently, a few arguments are outlined in order to reflect further on the application of the said criminal provision as it is currently applicable.
Probing mild-tempered neutralino dark matter through top-squark production at the LHC

description: The lightest neutralino, assumed to be the lightest supersymmetric particle, is proposed to be a dark matter (DM) candidate for the mass $\cal{O}$(100) GeV. Constraints from various direct dark matter detection experiments and Planck measurements exclude a substantial region of parameter space of the minimal supersymmetric standard model (MSSM). However, a "mild-tempered" neutralino with dominant bino composition and a little admixture of Higgsino is found to be a viable candidate for DM. Within the MSSM framework, we revisit the allowed region of parameter space that is consistent with all existing constraints. Regions of parameters that are not sensitive to direct detection experiments, known as "blind spots," are also revisited. Complimentary to the direct detection of DM particles, a mild-tempered neutralino scenario is explored at the LHC with the center of mass energy $\rm \sqrt{s}$=13 TeV through the top-squark pair production, and its subsequent decays with the standard-model-like Higgs boson in the final state. Our considered channel is found to be very sensitive also to the blind spot scenario. Detectable signal sensitivities are achieved using the cut-based method for the high luminosity options $\rm 300$ and $\rm 3000 ~fb^{-1}$, which are further improved by applying the multi-variate analysis technique.

GRB 060218 and the outliers with respect to the Ep-Eiso correlation

description: GRB 031203 and GRB 980425 are the two outliers with respect to the Ep-Eiso correlation of long GRBs. Recently Swift discovered a nearby extremely long GRB 060218 associated with a SN event. The spectral properties of this bursts are striking: on the one hand its broad band SED presents both thermal and non-thermal components which can be interpreted as due to the emission from the hot cocoon surrounding the GRB jet and as standard synchrotron self absorbed emission in the GRB prompt phase, respectively; on the other hand it is its long duration and its hard--to--soft spectral evolution which make this underluminous burst consistent with the Ep-Eiso correlation of long GRBs. By comparing the available spectral informations on the two major outliers we suggests that they might be twins of 060218 and, therefore, only apparent outliers with respect to the Ep_Eiso correlation. This interpretation also suggests that it is of primary importance the study the broad band spectra of GRBs in order to monitor their spectral evolution throughout their complete duration.

description: Typical observers in the universe do not follow the smooth Hubble expansion, but move relative to it. Such bulk peculiar motions introduce a characteristic scale that is closely analogous to the familiar Jeans length. This "peculiar Jeans length" marks the threshold below which relative-motion effects dominate the linear kinematics. There, cosmological measurements can vary considerably between the bulk-flow frame and that of the Hubble expansion, entirely due to the observers' relative motion. When dealing with the deceleration parameter, we find that the peculiar Jeans length varies between few and several hundred Mpc. On these scales, the deceleration parameter measured by the bulk-flow observers can be considerably larger (or smaller) than its Hubble-frame counterpart. This depends on whether the peculiar motion is locally expanding (or contracting), relative to the background expansion. Then, provided expanding and contracting bulk flows are randomly distributed, nearly half of the observers in the universe could be misled to think that their cosmos is over-decelerated. The rest of them, on the other hand, may come to believe that their universe is under-decelerated, or even accelerated in some cases. We make two phenomenological predictions that could in principle support this scenario.

description: Prominent in the `Field of Streams' -- the Sloan Digital Sky Survey map of substructure in the Galactic halo -- is an `Orphan Stream' without obvious progenitor. In this numerical study, we show a possible connection between the newly found dwarf satellite Ursa Major II (UMa II) and the Orphan Stream. We provide numerical simulations of the disruption of UMa II that match the observational data on the position, distance and morphology of the Orphan Stream. We predict the radial velocity of UMa II as -100 km/s as well as the existence of strong velocity gradients along the Orphan Stream. The velocity dispersion of UMa II is expected to be high, though this can be caused both by a high dark matter content or by the presence of unbound stars in a disrupted remnant. However, the existence of a gradient in the mean radial velocity across UMa II provides a clear-cut distinction between these possibilities. The simulations support the idea that some of the anomalous, young halo globular clusters like Palomar 1 or Arp 2 or Ruprecht 106 may be physically associated with the Orphan Stream.

description: IntroductionFluoride toxicity occurs when there is an excessive amount of fluoride ions in the body.Fluoride originates from fluorine, a naturally occurring and widespread element. Adding fluoride to drinking water helps lower the rate of tooth decay by promoting demineralization and remineralization of teeth. However, an excess of fluoride can cause dental fluorosis or skeletal fluorosis, potentially harming bones and joints.

description: We consider a graphene sheet folded in an arbitrary geometry, compact or with nanotube-like open boundaries. In the continuous limit, the Hamiltonian takes the form of the Dirac operator, which provides a good description of the low energy spectrum of the lattice system. We derive an index theorem that relates the zero energy modes of the graphene sheet with the topology of the lattice. The result coincides with analytical and numerical studies for the known cases of fullerene molecules and carbon nanotubes and it extend to more complicated molecules. Potential applications to topological quantum computation are discussed.

description: Variational quantum algorithms (VQAs) that estimate values of widely used physical quantities such as the rank, quantum entropies, the Bures fidelity and the quantum Fisher information of mixed quantum states are developed. In addition, variations of these VQAs are also adapted to perform other useful functions such as quantum state learning and approximate fractional inverses. The common theme shared by the proposed algorithms is that their cost functions are all based on minimizing the quantum purity of a quantum state. Strategies to mitigate or avoid the problem of exponentially vanishing cost function gradients are also discussed.

description: We present new photometry and spectroscopy of the eclipsing white dwarf - M-dwarf binary star RR Cae. We use timings of the primary eclipse from white-light photo-electric photometry to derive a new ephemeris for the eclipses. We find no evidence for any period change greater than Pdot/P ~ 5E-12 over a timescale of 10 years. We have measured the effective temperature of the white dwarf, T_WD, from an analysis of two high resolution spectra of RR Cae and find T_WD = (7540 +- 175)K. We estimate a spectral type of M4 for the companion from the same spectra. We have combined new spectroscopic orbits for the white dwarf and M-dwarf with an analysis of the primary eclipse and cooling models for helium white dwarfs to measure the mass and radius of the M-dwarf. The mass of the M-dwarf is (0.182 - 0.183) +- 0.013 Msun and the radius is (0.203 - 0.215) +- 0.013 Rsun, where the ranges quoted for these values reflect the range of white dwarf models used. In contrast to previous studies, which lacked a spectroscopic orbit for the white dwarf, we find that the mass and radius of the M-dwarf are normal for an M4 dwarf. The mass of the white dwarf is (0.440 +-0.022) Msun. With these revised masses and radii we find that RR Cae will become a cataclysmic variable star when the orbital period is reduced from its current value of 7.3 hours to 121 minutes by magnetic braking in 9-20 Gyr. We note that there is night-to-night variability of a few seconds in the timing of primary eclipse caused by changes to the shape of the primary eclipse. We speculate as to the possible causes of this phenomenon. (Abridged)

description: Ο κώδικας της Ιεράς Μονής Βλατάδων 72 αποτελεί χειρόγραφο Ευχολόγιον του 15ου αιώνα που προέρχεται από τη Θεσσαλονίκη. Είναι σημαντικός μάρτυρας της λειτουργικής παράδοσης της πόλεως σε μια εποχή που οι ιστορικές συνθήκες, π.χ. η τουρκοκρατία, οδηγούν την Εκκλησία σε μια καταγραφή της λειτουργικής της τάξεως. Το υπό εξέταση Ευχολόγιον αντικατοπτρίζει τη μοναχική λατρεία και παρουσιάζει την ύλη εκείνη του Ευχολογίου, το οποίο προορίζεται για χρήση από πρεσβύτερο (ιερομόναχο). Η Διάταξις της θείας Λειτουργίας που περιλαμβάνεται στον κώδικα είναι ένας σπουδαίος μάρτυρας του κειμένου, όπως αυτό εμφανίζεται σε πηγές του 14ου αιώνα. Γίνεται κριτική μεταγραφή του κειμένου της Διατάξεως και συγκριτική μελέτη σε σχέση με δύο άλλες πηγές, τα χειρόγραφα Παντελεήμονος 6277-770 (1347-1354) και Βατοπαιδίου 984 (1353-1365).
description: Codex Vlatadon Monastery 72 is a manuscript Euchologion of the 15th century. It was transcribe arguably in the city of Thessaloniki. It constitutes a significant witness of the liturgical tradition of that city during a time of historical unreast, due for example to the Ottoman conquest of the region, which lead the Church to consolidate and document its liturgical practice. The Euchologion studied reflects monastic worship and contains the material of the Euchologion that is used by a presbyter (hieromonk). The Diataxis of the Divine Liturgy of the codex is an imporant witness of its textual tradition, as it is found in manuscript sources of the 14th century. There is a critical transcription of the text of Diataxis and a comparative study in relation to two other sources, Panteleimon Manuscripts 6277-770 (1347-1354) and Vatopediou 984 (1353-1365)
Surface states influence in the conductance spectra of Co adsorbed on Cu(111)

description: We calculate the conductance spectra of a Co atom adsorbed on Cu(111), considering the Co $3d$ orbitals within a correlated multiple configurations model interacting through the substrate band with the Co $4s$ orbital, which is treated in a mean-field like approximation. By symmetry, only the $d_{z^2}$ orbital couples with the $s$ orbital through the Cu bands, and the interference between both conduction channels introduces a zero-bias anomaly in the conductance spectra. We find that, while the Kondo resonance is mainly determined by the interaction of the Co $d$ orbitals with the bulk states of the Cu(111) surface, a proper description of the contribution given by the coupling with the localized surface states to the Anderson widths is crucial to describe the interference line shape. We find that the coupling of the Co $4s$ orbital with the Shockley surface states is responsible of two main features observed in the measured conductance spectra, the dip shape around the Fermi energy and the resonance structure at the surface state low band edge.

description: This paper proposes a task-driven computational framework for assessing diffusion MRI experimental designs which, rather than relying on parameter-estimation metrics, directly measures quantitative task performance. Traditional computational experimental design (CED) methods may be ill-suited to experimental tasks, such as clinical classification, where outcome does not depend on parameter-estimation accuracy or precision alone. Current assessment metrics evaluate experiments' ability to faithfully recover microstructural parameters rather than their task performance. The method we propose addresses this shortcoming. For a given MRI experimental design, experiments are simulated start-to-finish and task performance is computed from ROC curves and associated summary metrics (e.g. AUC). Two experiments were performed: first, a validation of the pipeline's task performance predictions against clinical results, comparing in-silico predictions to real-world ROC/AUC; and second, a demonstration of the pipeline's advantages over traditional CED approaches, using two simulated clinical classification tasks. Comparison with clinical datasets validates our method's predictions of (a) the qualitative form of ROC curves, (b) the relative task performance of different experimental designs, and (c) the absolute performance of each experimental design. Furthermore, we show that our method outperforms traditional task-agnostic assessment methods, enabling improved, more useful experimental design. Compared to current approaches, such task-driven assessment is more likely to identify experimental designs that perform well in practice. Our method is not limited to diffusion MRI; the pipeline generalises to any task-based quantitative MRI application, and provides the foundation for developing future task-driven end-to end CED frameworks.

description: We study the transport of atoms across a localized Bose-Einstein condensate in a one-dimensional optical lattice. For atoms scattering off the condensate we predict total reflection as well as full transmission for certain parameter values on the basis of an exactly solvable model. The findings of analytical and numerical calculations are interpreted by a tunable Fano-like resonance and may lead to interesting applications for blocking and filtering atom beams.

description: For suitable cosmological backgrounds, thermal fluctuations of a gas of strings can generate a scale-invariant spectrum of cosmological fluctuations without requiring a phase of inflationary expansion. We highlight the key points of this mechanism, and discuss cosmological backgrounds in which this scenario can be realized. The spectrum of cosmological perturbations has a small red tilt (like in scalar field-driven inflation) but (unlike in inflation) there is a small blue tilt of the spectrum of gravitational waves.

description: A significant number of Kondo-lattice ferromagnets order perpendicular to the easy magnetization axis dictated by the crystalline electric field. The nature of this phenomenon has attracted considerable attention, but remains poorly understood. In the present paper we use inelastic neutron scattering supported by magnetization and specific heat measurements to study the spin dynamics in the hard-axis ferromagnet CeAgSb2. In the zero field state we observed two sharp magnon modes, which are associated with Ce ordering and extended up to $\approx 3 meV with a considerable spin gap of 0.6 meV. Application of a magnetic field perpendicular to the moment direction reduces the spectral intensity and suppresses the gap and significantly enhances the low-temperature specific heat at a critical field of Bc ~ 2.8 T via a mean-field-like transition. Above the transition, in the field polarized state, the gap eventually reopens due to the Zeeman effect. We modeled the observed dispersion using linear spin-wave theory (LSWT) taking into account the ground state Gamma 6 doublet and exchange anisotropy. Our model correctly captures the essential features of the spin dynamics including magnetic dispersion, distribution of the spectral intensity as well as the field-induced behavior, although several minor features remain obscure. The observed spectra do not show significant broadening due to the finite lifetime of the quasiparticles. Along with a moderate electronic specific heat coefficient gamma = 46 mJ/mol K2 this indicates that the Kondo coupling is relatively weak and the Ce moments are well localized. Altogether, our results provide profound insight into the spin dynamics of the hard-axis ferromagnet CeAgSb2 and can be used as solid ground for studying magnetic interactions in isostructural compounds including CeAuSb2, which exhibits nematicity and unusual mesoscale magnetic textures.

description: We find non-rational conformal field theories in two dimensions, which are solvable due to their correlators being related to correlators of Liouville theory. Their symmetry algebra consists of the dimension-two stress-energy tensor, and two dimension-one fields. The theories come in a family with two parameters: the central charge c and a complex number m. The special case m=0 corresponds to Liouville theory (plus two free bosons), and m=1 corresponds to the H3+ model. In the case m=2 we show that the correlators obey third-order differential equations, which are associated to a subsingular vector of the symmetry algebra.

description: We exhibit explicit expressions, in terms of components, of discriminants, determinants, characteristic polynomials and polynomial identities for matrices of higher rank. We define permutation tensors and in term of them we construct discriminants and the determinant as the discriminant of order $d$, where $d$ is the dimension of the matrix. The characteristic polynomials and the Cayley--Hamilton theorem for higher rank matrices are obtained there from.
