description: The proton analysing power in $\vec{p}p$ elastic scattering has been measured at small angles at COSY-ANKE at 796 MeV and five other beam energies between 1.6 and 2.4 GeV using a polarised proton beam. The asymmetries obtained by detecting the fast proton in the ANKE forward detector or the slow recoil proton in a silicon tracking telescope are completely consistent. Although the analysing power results agree well with the many published data at 796 MeV, and also with the most recent partial wave solution at this energy, the ANKE data at the higher energies lie well above the predictions of this solution at small angles. An updated phase shift analysis that uses the ANKE results together with the World data leads to a much better description of these new measurements.

Saturn Ring Seismology: Evidence for Stable Stratification in the Deep Interior of Saturn
Creators: name: Fuller, Jim
Publisher: name: arXiv
Year: 2014
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Seismology allows for direct observational constraints on the interior structures of stars and planets. Recent observations of Saturn's ring system have revealed the presence of density waves within the rings excited by oscillation modes within Saturn, allowing for precise measurements of a limited set of the planet's mode frequencies. We construct interior structure models of Saturn, compute the corresponding mode frequencies, and compare them with the observed mode frequencies. The fundamental mode frequencies of our models match the observed frequencies (of the largest amplitude waves) to an accuracy of $\sim 1 \%$, confirming that these waves are indeed excited by Saturn's f-modes. The presence of the lower amplitude waves (finely split in frequency from the f-modes) can only be reproduced in models containing gravity modes that propagate in a stably stratified region of the planet. The stable stratification must exist deep within the planet near the large density gradients between the core and envelope. Our models cannot easily reproduce the observed fine splitting of the $m=-3$ modes, suggesting that additional effects (e.g., significant latitudinal differential rotation) may be important.

description: Accurately modeling astrophysical extreme-mass-ratio-insprials requires calculating the gravitational self-force for orbits in Kerr spacetime. The necessary calculation techniques are typically very complex and, consequently, toy scalar-field models are often developed in order to establish a particular calculational approach. To that end, I present a calculation of the scalar-field self-force for a particle moving on a (fixed) inclined circular geodesic of a background Kerr black hole. I make the calculation in the frequency-domain and demonstrate how to apply the mode-sum regularization procedure to all four components of the self-force. I present results for a number of strong-field orbits which can be used as benchmarks for emerging self-force calculation techniques in Kerr spacetime.

description: We report on parallel production of Bose-Einstein condensates (BECs) in steerable, multi-plexed crossed optical dipole traps. Using a conventional trap-weakening evaporation scheme, where the optical trapping power is lowered, we obtain an array of up to four independent BECs. To improve evaporation efficiency, we propose to target each crossed trap site with a narrow auxiliary laser beam, creating an escape channel for energetic atoms. We experimentally demonstrate runaway evaporation using this scheme, which is characterized by very modest weakening in atomic confinement such that high densities and elastic collision rates can be maintained. Based on discretely time-shared optical tweezers, our approach is particularly suited for addressing the problem of simultaneously cooling atoms in multiple traps clouds, providing the freedom to act locally and in a tailored fashion at individual trap sites.

Σε στρεσογόνες περιόδους, όπως κατά τη διάρκεια της πανδημίας Covid-19, οι εργαζόμενοι βιώνουν ακόμα περισσότερο εργασιακό άγχος, κάτι που καθιστά ακόμα πιο επιβεβλημένη την ενίσχυση της ψυχικής ανθεκτικότητας. Σκοπός: Σκοπός της μελέτης είναι η διερεύνηση της ψυχικής ανθεκτικότητας των εργαζομένων του Εθνικού Οργανισμού Παροχής Υπηρεσιών Υγείας (ΕΟΠΥΥ) κατά την περίοδο της πανδημίας, η οποία δημιούργησε ιδιαίτερες συνθήκες προσωπικής και επαγγελματικής ζωής. Υλικό και μέθοδος: Πραγματοποιήθηκε μία ποσοτική έρευνα με ερωτηματολόγιο και πιο συγκεκριμένα την Κλίμακα Ανθεκτικότητας CD-RISC (CD-RISC). Το δείγμα αποτελείται από 168 ερωτηθέντες. Αποτελέσματα: Το δείγμα εργαζομένων του ΕΟΠΥΥ διέπεται από ένα μέτριο επίπεδο ψυχικής ανθεκτικότητας, δεδομένου ότι τα αποτελέσματα κατέδειξαν τα εξής: α) Προσωπική απόδοση: 23.27 / 32.00, β) Ανεκτικότητα: 18.41 / 28.00, γ) Προσαρμογή στην αλλαγή: 15.03 / 20.00, δ) Πνευματικές επιδράσεις: 4.63 / 8.00, ε) Έλεγχος: 8.31 / 12.00. Επίσης, ορισμένα δημογραφικά (γυναίκα, κάτοχος πτυχίου) και επαγγελματικά χαρακτηριστικά (ανώτερα στελέχη, περισσότερα έτη προϋπηρεσίας) των εργαζομένων του ΕΟΠΥΥ επηρεάζουν την ψυχική τους ανθεκτικότητα. Συμπεράσματα: Από την παρούσα έρευνα καταδείχθηκε πως το δείγμα των εργαζομένων του ΕΟΠΠΥ διέπεται από ένα μέτριο επίπεδο ψυχικής ανθεκτικότητας και πως αυτό το επίπεδο επηρεάζεται από ορισμένους δημογραφικούς και επαγγελματικούς παράγοντες. Επομένως, κρίνεται απαραίτητο να υπάρξουν περαιτέρω έρευνες προς αυτήν την κατεύθυνση, αλλά και πρωτοβουλίες σε ατομικό και οργανωσιακό επίπεδο για την ενίσχυση της ψυχικής ανθεκτικότητας των εργαζομένων.

Σκοπός της διπλωματικής εργασίας είναι να εντοπιστούν τα εμπόδια και οι δυσκολίες που προκύπτουν από τη χρήση της κλασσικής φορτωτικής, η αναγκαιότητα της ηλεκτρονικής φορτωτικής και τα πλεονεκτήματά της, καθώς και τα νομικά ζητήματα που προκύπτουν από τη χρήση της, με έμφαση στα ζητήματα υπογραφής και γνησιότητας. Οι ηλεκτρονικές συναλλαγές αυξάνονται με ταχείς ρυθμούς, γεγονός που οδηγεί στη σταδιακή αντικατάσταση της κλασσικής φορτωτικής από την ηλεκτρονική. Λόγω των πολλών πλεονεκτημάτων των ηλεκτρονικών εγγράφων, πολλά έγγραφα στη ναυτιλιακή βιομηχανία, συμπεριλαμβανομένων των φορτωτικών, έχουν αντικατασταθεί από ηλεκτρονικά. Τα χαρακτηριστικά των τριών κύριων λειτουργιών της παραδοσιακής φορτωτικής, δηλαδή οι λειτουργίες της απόδειξης παραλαβής εμπορεύματος, η απόδειξη της σύμβασης μεταφοράς και η χρήση ως έγγραφο απόδειξης της κυριότητας, εγείρουν ερωτήματα σχετικά με το κατά πόσον η ηλεκτρονική φορτωτική αναπαράγει αυτές τις λειτουργίες, κατά πόσον η δυνατότητα διαπραγμάτευσης επιτυγχάνεται κατά τη χρήση ηλεκτρονικών συστημάτων και τον τρόπο με τον οποίο θα γίνει η δυνατότητα μεταφοράς. Επιπλέον, θα πρέπει να εξεταστούν ζητήματα που προκύπτουν σχετικά με τη νομιμότητα, την εμπιστευτικότητα και την ασφάλεια της ηλεκτρονικής φορτωτικής. Για την αντιμετώπιση όλων των νομικών ζητημάτων που προκύπτουν, θα εξεταστούν διεθνείς κανονισμοί, όπως ο κανονισμός της UNCITRAL για το ηλεκτρονικό εμπόριο και οι κανόνες της CMI για τις ηλεκτρονικές φορτωτικές. Λαμβάνοντας υπόψη την ανάλυση των τεσσάρων εγκεκριμένων επίσημων ηλεκτρονικών λογαριασμών των συστημάτων έκδοσης φορτωτικής, δηλαδή των Bolero, essDocs, E-titleTM και EdoxOnline, τα προβλήματα της δυνατότητας διαπραγμάτευσης και της διαδικασίας μεταφοράς αποτέλεσαν σημαντική πηγή ανησυχίας στον τομέα της ναυτιλίας.

description: As our societies advance through what is known as the fourth industrial revolution, the amount of published open government data has escalated over the past few decades, as it is considered a critical driver of competitiveness and a catalyst for solving social and sustainability challenges. Combining different sectors and perspectives, the project 'Towards a sustainable Open Data ECOsystem' (ODECO) aims to address the central challenges of realising a user-driven, circular, inclusive, open data ecosystem. Understanding open government data from an ecosystem perspective can help identify opportunities and challenges to unleash its potential. We invite interested parties to take part in the project.

description: Despite the classical interpretation of RR Lyrae as old and metal-poor population II stars, it is well known that metal-rich (up to solar values) RR Lyrae stars exist in the solar vicinity. Thanks to the unprecedented Gaia capabilities, we found that the metal-rich RR Lyrae stars are present all over the Galactic thin-disc, well beyond the Solar neighborhood. The kinematics of these stars is consistent with a young (less than 6 Gyr) thin-disc population. An age of only a few Gyrs would be very difficult to reconcile with the conventional scenarios of the RR Lyrae formation, for which more metal-rich stars are expected to be the oldest. At the same time, assuming that they are instead truly old implies that they are tracing one of the oldest components of the Milky Way. Alternative formation channels for RR Lyrae can be called into play to solve this conundrum. In particular, in this poster, I will present the results of a set of MESA binary simulations showing that is theoretically possible to produce a population of metal-rich RR Lyrae with ages consistent with the thin-disc populations. The results of this work have an important impact both for the Galactic archaeology and for the calibration of the Roche-Lobe overflow mass-transfer.

description: The X-ray spectra of active galactic nuclei (AGN) unveil properties of matter around the super massive black hole (SMBH). We investigate the X-ray spectra of AGN focusing on Compton reflection and fluorescence, important processes of interaction between primary radiation and circum-nuclear material. Unresolved emission lines (most notably the Fe line) in the X-ray spectra of AGN indicate that this material is located far away from the SMBH. Contributions from the inner accretion disk, affected by relativistic effects, have also been detected in several cases. We studied the average X-ray spectrum of a sample of 263 X-ray unabsorbed AGN that yield 419023 counts in the 2-12 keV rest-frame band distributed among 388 XMM-Newton spectra. We fitted the average spectrum using a (basically) unabsorbed power law (primary radiation). From second model that represents the interaction of the primary radiation with matter located far away from the SMBH, we found that it was very significantly detected. Finally, we added a contribution from interaction with neutral material in the accretion disk close to the central SMBH, which is therefore smeared by relativistic effects, which improved the fit at 6 sigma. The reflection factors are 0.65 for the accretion disk and 0.25 for the torus. Replacing the neutral disk-reflection with low-ionisation disk reflection, also relativistically smeared, fits the data equally well, suggesting that we do not find evidence for a significant ionisation of the accretion disk. We detect distant neutral reflection in the average spectrum of unabsorbed AGN with z=0.8. Adding the disk-reflection component associated with a relativistic Fe line improves the data description at 6 sigma confidence level, suggesting that both reflection components are present. The disk-reflection component accounts for about 70 % of the total reflected flux.

description: Knowledge of the severity of an influenza outbreak is crucial for informing and monitoring appropriate public health responses, both during and after an epidemic. However, case-fatality, case-intensive care admission and case-hospitalisation risks are difficult to measure directly. Bayesian evidence synthesis methods have previously been employed to combine fragmented, under-ascertained and biased surveillance data coherently and consistently, to estimate case-severity risks in the first two waves of the 2009 A/H1N1 influenza pandemic experienced in England. We present in detail the complex probabilistic model underlying this evidence synthesis, and extend the analysis to also estimate severity in the third wave of the pandemic strain during the 2010/2011 influenza season. We adapt the model to account for changes in the surveillance data available over the three waves. We consider two approaches: (a) a two-stage approach using posterior distributions from the model for the first two waves to inform priors for the third wave model; and (b) a one-stage approach modelling all three waves simultaneously. Both approaches result in the same key conclusions: (1) that the age-distribution of the case-severity risks is "u"-shaped, with children and older adults having the highest severity; (2) that the age-distribution of the infection attack rate changes over waves, school-age children being most affected in the first two waves and the attack rate in adults over 25 increasing from the second to third waves; and (3) that when averaged over all age groups, case-severity appears to increase over the three waves. The extent to which the final conclusion is driven by the change in age-distribution of those infected over time is subject to discussion.

description: While pressure balance can predict how far the magnetopause will move in response to an upstream pressure change, it cannot determine how fast the transient reponse will be. Using Time History of Events and Macroscale Interactions during Substorms (THEMIS), we present multipoint observations revealing, for the first time, strong (thermal + magnetic) pressure gradients in the magnetosheath due to a foreshock transient, most likely a Hot Flow Anomaly (HFA), which decreased the total pressure upstream of the bow shock. By converting the spacecraft time series into a spatial picture, we quantitatively show that these pressure gradients caused the observed acceleration of the plasma, resulting in fast sunward magnetosheath flows ahead of a localised outward distortion of the magnetopause. The acceleratation of the magnetosheath plasma was fast enough to keep the peak of the magnetopause bulge at approximately the equilibrium position i.e. in pressure balance. Therefore, we show that pressure gradients in the magnetosheath due to transient changes in the total pressure upstream can directly drive anomalous flows and in turn are important in transmitting information from the bow shock to the magnetopause.
Higher spins in AdS_5 at one loop: vacuum energy, boundary conformal anomalies and AdS/CFT

description: We consider general-symmetry higher spin fields in AdS_5 and derive expressions for their one-loop corrections to vacuum energy E and the associated 4d boundary conformal anomaly a-coefficient. We a propose a similar expression for the second conformal anomaly c-coefficient. We show that all the three quantities (E, a, c) computed for N=8 gauged 5d supergravity are -1/2 of the values for N=4 conformal 4d supergravity and also twice the values for N=4 Maxwell multiplet. This gives 5d derivation of the fact that the system of N=4 conformal supergravity and four N=4 Maxwell multiplets is anomaly free. The values of (E, a, c) for the states at level p of Kaluza-Klein tower of 10d type IIB supergravity compactified on S^5 turn out to be equal to those for p copies of N=4 Maxwell multiplets. This may be related to the fact that these states appear in the tensor product of p superdoubletons. Under a natural regularization of the sum over p, the full 10d supergravity contribution is then minus that of the Maxwell multiplet, in agreement with the standard adjoint AdS/CFT duality (SU(n) SYM contribution is n^2-1 of one Maxwell multiplet). We also verify the matching of (E, a, c) for spin 0 and 1/2 boundary theory cases of vectorial AdS/CFT duality. The consistency conditions for vectorial AdS/CFT turn out to be equivalent to the cancellation of anomalies in the closely related 4d conformal higher spin theories. In addition, we study novel example of vectorial AdS/CFT duality when the boundary theory is described by free spin 1 fields and is dual to a particular higher spin theory in AdS_5 containing fields in mixed-symmetry representations. We also discuss its supersymmetric generalizations.

description: Salt-affected soils pose significant challenges to agricultural productivity and environmental
sustainability. These soils contain elevated levels of soluble salts and often exhibit adverse conditions
for plant growth, including high salinity, sodicity, and limited nutrient availability. Additionally, the
behavior of trace elements in salt-affected soils can exacerbate soil quality issues and impact plant
health. This review aims to provide a comprehensive analysis of the behavior of trace elements in saltaffected
soils, focusing on their mobility, availability, and potential impacts on agricultural systems and
ecosystems. The review highlights key factors influencing trace element behavior, such as soil
properties, redox conditions, and the presence of competing ions. Furthermore, the role of management
practices in mitigating trace element-related issues in salt-affected soils is discussed. The review
concludes with recommendations for future research directions and sustainable soil management
strategies to address trace element dynamics in salt-affected soils, ensuring improved agricultural
productivity and environmental stewardship.

description: This paper is devoted to the numerical study of diffraction by periodic structures of plane waves under oblique incidence. For this situation Maxwell's equations can be reduced to a system of two Helmholtz equations in ℝ2 coupled via quasiperiodic transmission conditions on the piecewise smooth interfaces between different materials. The numerical analysis is based on a strongly elliptic variational formulation of the differential problem in a bounded periodic cell involving nonlocal boundary operators. We obtain existence and uniqueness results for discrete solutions and provide the corresponding error analysis.

SEED

description: Diese Arbeit befasst sich mit der Frage, inwiefern die SEED bei Kindern mit Autismus-Spektrum-Störung und kognitiver Beeinträchtigung eine Einschätzung des emotionalen Entwicklungsstandes aufzeigen kann.
Theoretische Grundlagen zur emotionalen Entwicklung und Autismus-Spektrum-Störung werden aufbereitet. Die SEED als Diagnostikinstrument wird in ihrem Konzept und in ihrer Anwendung detailliert vorgestellt. In einer Vergleichsstudie wird die SEED auf deren Anwenderfreundlichkeit, Nutzwert und die Durchführbarkeit bei Kindern mit ASS untersucht.
Es wird die Kenntnis erlangt, dass die SEED für alle Kinder mit einer intellektuellen Entwicklungsstörung gleichermassen gut anwendbar und von grossem Nutzen ist. Für die Arbeit in der Betreuung und Förderung von kognitiv beeinträchtigten Kindern empfiehlt sich die SEED. Eine institutionell verankerte Anwendung der SEED wäre zukunftsorientiert und wünschenswert.

description: Im Rahmen des Projekts MINTplus wurde das Lehramtsstudium an der Technischen Universität Darmstadt mit Beginn des Wintersemesters 2017/18 neu strukturiert. Als innovatives Studienelement wurde der interdisziplinäre Vernetzungsbereich eingeführt. Durch die neuen Veranstaltungen aus diesem Studienbereich sollen die sonst nur nebeneinanderstehenden und jeweils in die Bereiche Fachwissenschaft und Fachdidaktik untergliederten Fächer sowie die Bildungswissenschaften miteinander verknüpft werden. Eine der neuen Veranstaltungen ist das Modul „Erkenntnisgewinnung in den Naturwissenschaften“, das im Folgeprojekt MINTplus2 konzipiert wurde. Der nachfolgende Beitrag stellt an der Entwicklung dieses Moduls exemplarisch dar, wie durch den Vernetzungsbereich eine strukturelle Voraussetzung geschaffen wurde, um kooperativ ein mit anderen Disziplinen abgestimmtes Modul zu konzipieren, dessen Thematik über die eigentlichen Fächergrenzen der verantwortlichen Person hinausgeht. Anknüpfend an das Thema dieses Heftes werden so Möglichkeiten einer interdisziplinären Vernetzung innerhalb der Lehrerbildung an einer Hochschule aufgezeigt, die dazu beitragen, einen Mehrwert für die Lehrerbildung zu generieren. Im Anschluss an die Darstellung des modularen Entwicklungsprozesses wird das Kurskonzept erläutert und ein Einblick in dessen bisherige Umsetzung gegeben. Anhand exemplarischer Zitate wird aufgezeigt, dass das intendierte Ziel der Vernetzung auch von den Studierenden wahrgenommen wurde.

description: Die hochschulbasierte Ausbildung zukünftiger Lehrkräfte hat in der jüngeren Vergangenheit nicht zuletzt durch die Förderung der „Qualitätsoffensive Lehrerbildung“ (QLB) sowohl in den Bildungswissenschaften als auch in den Fachdidaktiken einen Professionalisierungs- und Forschungsschub erfahren. Eine besondere Position nehmen dabei die Fachwissenschaften ein: In ihnen ist Lehrerbildung oftmals kein genuiner Bezugspunkt für forschungsbasierte Aktivitäten, was vermutlich hauptsächlich daran liegt, dass Disziplinen bzw. Fächer ihre eigene Didaktik eher den Bildungswissenschaften als der eigenen Fachkultur zuordnen. Diese Haltung kann sowohl historisch als auch institutionell erklärt werden und stellt ein grundlegendes Problem dar, das fächer- und universitätsübergreifend zu beobachten ist. Im Lichte dieses Befundes lautet die Schlüsselfrage, wie Forschung im Kontext von Lehrerbildung und allgemeine fachwissenschaftliche Forschung in höherem Maße aufeinander bezogen werden können.

Composable security proof for continuous-variable quantum key distribution with coherent states

Publisher: name: arXiv

Subjects: subject: Quantum Physics (quant-ph)

description: We give the first composable security proof for continuous-variable quantum key distribution with coherent states against collective attacks. Crucially, in the limit of large blocks the secret key rate converges to the usual value computed from the Holevo bound. Combining our proof with either the de Finetti theorem or the Postselection technique then shows the security of the protocol against general attacks, thereby confirming the long-standing conjecture that Gaussian attacks are optimal asymptotically in the composable security framework. We expect that our parameter estimation procedure, which does not rely on any assumption, will find applications elsewhere, for instance for the reliable quantification of continuous-variable entanglement in finite-size settings.

Active space decomposition with multiple sites: Density matrix renormalization group algorithm

description: We extend the active space decomposition method, recently developed by us, to more than two active sites using the density matrix renormalization group algorithm. The fragment wave functions are described by complete or restricted active-space wave functions. Numerical results are shown on a benzene pentamer and a perylene diimide trimer. It is found that the truncation errors in our method decrease almost exponentially with respect to the number of renormalization states M, allowing for numerically exact calculations (to a few microhartrees or less) with M = 128 in both cases. This rapid convergence is because the renormalization steps are used only for the interfragment electron correlation.

description: The recent COVID-19 pandemic has forced educational institutions worldwide to adopt e-learning, which
has presented both challenges and opportunities for students and teachers. This study aimed to investigate
the effectiveness of e-learning games in enhancing pupils' learning behaviors in social studies education.
The study utilized a descriptive correlational research design and purposive sampling technique to gather
data from 45 grade six students through an adapted-modified survey questionnaire. The study found a
positive significant relationship between interest, confidence, motivation, and usefulness that is consistent
with students' learning behavior in social studies. The findings also showed that e-learning games were
helpful in increasing students' interest in the subject, which suggests that using e-learning games as a
teaching tool can enhance students' learning behavior. The study recommends further scrutiny on the
enjoyment of e-learning games as applied in other disciplines. These findings are consistent with previous
research that has shown the positive impact of educational games on student learning.

description: Distinguishing hot from cold is the most primitive form of thermometry. Here we consider how well this task can be performed using a single qubit to distinguish between two different temperatures of a bosonic bath. In this simple setting, we find that letting the qubit equilibrate with the bath is not optimal, and depending on the interaction time it may be advantageous for the qubit to start in a state with some quantum coherence. We also briefly consider the case that the qubit is initially entangled with a second qubit that is not put into contact with the bath, and show that entanglement allows for even better thermometry.

Friedmann equations from nonequilibrium thermodynamics of the Universe: A unified formulation for modified gravity

description: Inspired by the Wald-Kodama entropy $S=A/(4G_{\text{eff}})$ where $A$ is the horizon area and $G_{\text{eff}}$ is the effective gravitational coupling strength in modified gravity with field equation $R_{μν}-Rg_{μν}/2=$ $8πG_{\text{eff}} T_{μν}^{\text{(eff)}}$, we develop a unified and compact formulation in which the Friedmann equations can be derived from thermodynamics of the Universe. The Hawking and Misner-Sharp masses are generalized by replacing Newton's constant $G$ with $G_{\text{eff}}$, and the unified first law of equilibrium thermodynamics is supplemented by a nonequilibrium energy dissipation term $\mathcal{E}$ which arises from the revised continuity equation of the perfect-fluid effective matter content and is related to the evolution of $G_{\text{eff}}$. By identifying the mass as the total internal energy, the unified first law for the interior and its smooth transit to the apparent horizon yield both Friedmann equations, while the nonequilibrium Clausius relation with entropy production for an isochoric process provides an alternative derivation on the horizon. We also analyze the equilibrium situation $G_{\text{eff}}=G=\text{constant}$, provide a viability test of the generalized geometric masses, and discuss the continuity/conservation equation. Finally, the general formulation is applied to the FRW cosmology of minimally coupled $f(R)$, generalized Brans-Dicke, scalar-tensor-chameleon, quadratic, $f(R,\mathcal{G})$ generalized Gauss-Bonnet and dynamical Chern-Simons gravity. In these theories we also analyze the $f(R)$-Brans-Dicke equivalence, find that the chameleon effect causes extra energy dissipation and entropy production, geometrically reconstruct the mass $ρ_m V$ for the physical matter content, and show the self-inconsistency of $f(R,\mathcal{G})$ gravity in problems involving $G_{\text{eff}}$.

Computable Jordan Decomposition of Linear Continuous Functionals on $C[0;1]$

description: By the Riesz representation theorem using the Riemann-Stieltjes integral, linear continuous functionals on the set of continuous functions from the unit interval into the reals can either be characterized by functions of bounded variation from the unit interval into the reals, or by signed measures on the Borel-subsets. Each of these objects has an (even minimal) Jordan decomposition into non-negative or non-decreasing objects. Using the representation approach to computable analysis, a computable version of the Riesz representation theorem has been proved by Jafarikhah, Lu and Weihrauch. In this article we extend this result. We study the computable relation between three Banach spaces, the space of linear continuous functionals with operator norm, the space of (normalized) functions of bounded variation with total variation norm, and the space of bounded signed Borel measures with variation norm. We introduce natural representations for defining computability. We prove that the canonical linear bijections between these spaces and their inverses are computable. We also prove that Jordan decomposition is computable on each of these spaces.
Mass spectral analysis and quantification of Secondary Ion Mass Spectrometry data

description: This work highlights the possibility of improving the quantification aspect of Cs-complex ions in SIMS (Secondary Ion Mass Spectrometry), by combining the intensities of all possible Cs-complexes. Identification of all possible Cs-complexes requires quantitative analysis of mass spectrum from the material of interest. The important steps of this mass spectral analysis include constructing fingerprint mass spectra of the constituent species from the table of isotopic abundances of elements, constructing the system(s) of linear equations to get the intensities of those species, solving them, evaluating the solutions and employing a regularization process when required. These steps are comprehensively described and the results of their application on a SIMS mass spectrum obtained from D9 steel are presented. It is demonstrated that results from the summation procedure, which covers entire range of sputtered clusters, is superior to results from single Cs-complex per element. The result of employing a regularization process in solving a mass spectrum from an SS316LN steel specimen is provided to demonstrate the necessity of regularization.

description: We derive several new results for Renyi entropy, $S_n$, across generic entangling surfaces. We establish a perturbative expansion of the Renyi entropy, valid in generic quantum field theories, in deformations of a given density matrix. When applied to even-dimensional conformal field theories, these results lead to new constraints on the $n$-dependence, independent of any perturbative expansion. In 4d CFTs, we show that the $n$-dependence of the universal part of the ground state Renyi entropy for entangling surfaces with vanishing extrinsic curvature contribution is in fact fully determined by the Renyi entropy across a sphere in flat space. Using holography, we thus provide the first computations of Renyi entropy across non-spherical entangling surfaces in strongly coupled 4d CFTs. Furthermore, we address the possibility that in a wide class of 4d CFTs, the flat space spherical Renyi entropy also fixes the $n$-dependence of the extrinsic curvature contribution, and hence that of arbitrary entangling surfaces. Our results have intriguing implications for the structure of generic modular Hamiltonians.

description: By applying Darboux-Crum transformations to the quantum one-gap Lame system, we introduce an arbitrary countable number of bound states into forbidden bands. The perturbed potentials are reflectionless and contain two types of soliton defects in the periodic background. The bound states with finite number of nodes are supported in the lower forbidden band by the periodicity defects of the potential well type, while the pulse type bound states in the gap have infinite number of nodes and are trapped by defects of the compression modulations nature. We investigate the exotic nonlinear N=4 supersymmetric structure in such paired Schrodinger systems, which extends an ordinary N=2 supersymmetry and involves two bosonic generators composed from Lax-Novikov integrals of the subsystems. One of the bosonic integrals has a nature of a central charge, and allows us to liaise the obtained systems with the stationary equations of the Korteweg-de Vries and modified Korteweg-de Vries hierarchies. This exotic supersymmetry opens the way for the construction of self-consistent condensates based on the Bogoliubov-de Gennes equations and associated with them new solutions to the Gross-Neveu model. They correspond to the kink or kink-antikink defects of the crystalline background in dependence on whether the exotic supersymmetry is unbroken or spontaneously broken.
