description: Η Θερμομηχανική και ειδικότερα η μελέτη των παραμενουσών τάσεων κατά την συγκόλληση κράματος αλουμινίου με laser CO2, είναι το αντικείμενο της συγκεκριμένης εργασίας. Για την ανάπτυξη της εργασίας έγινε προσομοίωση συγκόλλησης λεπτών ελασμάτων κατασκευασμένα από κράμα αλουμίνιο Α1 2024. Τα κράματα αλουμινίου, λόγω των χαρακτηριστικών ιδιοτήτων τους , είναι σήμερα από τα βασικά δομικά υλικά σε κατασκευαστικές δραστηριότητες. Οι συγκολλήσεις με δέσμη laser (Laser Beam Welding, LBW) έχουν γίνει πλέον κοινή πρακτική στις γραμμές. Αποτελεί σημαντικό βήμα για την παραγωγή μεταλλικών κατασκευαστικών στοιχείων υψηλής ολοκλήρωσης. Στις μέρες μας η μέθοδος αυτή, αναπτύσσεται ραγδαία και τείνει να αντικαταστήσει πολλές από τις συμβατικές μεθόδους συγκόλλησης. Η πτυχιακή εργασία χρησιμοποιεί ως βασικό αποδεικτικό εργαλείο τον αριθμητικό υπολογισμό με χρήση της μεθόδου των πεπερασμένων στοιχείων χρησιμοποιώντας την πλατφόρμα ABAQUS. Κατασκευάστηκε τριδιάστατο αριθμητικό μοντέλο προσομοίωσης. Δεδομένου ότι η εύστοχη και ταχεία «πρόβλεψη» αποτελεί σήμερα το ζητούμενο στη ναυπηγική και στην αεροναυπηγική βιομηχανία, το μοντέλο αυτό αποσκοπεί στο να «προβλέψει» τη θερμική και μηχανική απόκριση των προς συγκόλληση ελασμάτων πριν την πραγματοποίηση των ίδιων των συγκολλήσεων. Εν κατακλείδι παρουσιάζονται τα αποτελέσματα της προσομοίωσης, σχολιάζονται και προτείνεται βελτιωμένα μοντέλα για μελλοντικές έρευνες.

description: Despite the promise of equality in radical, socialist form, the Bolsheviks quickly became the nucleus of the new elite and ruling class in the Soviet Union. A practical viewpoint regarding this result is founded on viewing the revolution as a state-making process, instead of a complete upheaval of power structures. This allows us to compare continuities and differences between Imperial Russian and Soviet foreign policy, based on the roles of elites in their formulation. An overview of the foundations of Russian foreign policy from the mid-19th century is related to two cases of Soviet foreign policy, during the Russian civil war and the 1920s, respectively. The comparison shows a significant change from exclusive to inclusive elites. However, coherence remained high in both elites. Although both polities faced similar constraints, the solutions of the elites in addressing them differed radically.

description: Transition of a system between two states is an important but difficult problem in natural science. In this article we study the transition problem in the framework of transition path ensemble. Using the overdamped Langevin method, we introduce the path integral formulation of the transition probability and obtain the equation for the minimum action path in the transition path space. For the effective sampling in the transition path ensemble, we derive a conditional overdamped Langevin equation. In two exactly solvable models, the free particle system and the harmonic system, we present the expression of the conditional probability density and the explicit solutions for the conditional Langevin equation and the minimum action path. The analytic results demonstrate the consistence of the conditional Langevin equation with the desired probability distribution in the transition. It is confirmed that the conditional Langevin equation is an effective tool to sample the transition path ensemble, and the minimum action principle actually leads to the most probable path.

description: An arbitrary lossless transformation in high-dimensional quantum space can be decomposed into elementary operations which are easy to implement, and an effective decomposition algorithm is important for constructing high-dimensional systems. Here, we present two optimized architectures to effectively realize an arbitrary unitary transformation by using the photonic path and polarization based on the existing decomposition algorithm. In the first architecture, the number of required interferometers is reduced by half compared with previous works. In the second architecture, by using the high-dimensional X gate, all the elementary operations are transferred to the operations which act locally on the photonic polarization in the same path. Such an architecture could be of significance in polarization-based applications. Both architectures maintain the symmetric layout. Our work facilitates the optical implementation of high-dimensional transformations and could have potential applications in high-dimensional quantum computation and quantum communication.

description: Hamiltonian light-front quantum field theory provides a framework for calculating both static and dynamic properties of strongly interacting relativistic systems. Invariant masses, correlated parton amplitudes and time-dependent scattering amplitudes, possibly with strong external time-dependent fields, represent a few of the important applications. By choosing the light-front gauge and adopting an orthonormal basis function representation, we obtain a large, sparse, Hamiltonian matrix eigenvalue problem for mass eigenstates that we solve by adapting ab initio no-core methods of nuclear many-body theory. In the continuum limit, the infinite matrix limit, we recover full covariance. Guided by the symmetries of light-front quantized theory, we adopt a two-dimensional harmonic oscillator basis for transverse modes that corresponds with eigensolutions of the soft-wall anti-de Sitter/quantum chromodynamics (AdS/QCD) model obtained from light-front holography. We outline our approach and present results for non-linear Compton scattering, evaluated non-perturbatively, where a strong and time-dependent laser field accelerates the electron and produces states of higher invariant mass i.e. final states with photon emission.

title: Elucidating the relationship between sensory reactivity and anxiety in autism
Creators: name: MacLennan, Keren
Publisher: name: University of Reading
Year: 2022

description: Sensory reactivity differences are commonly experienced by autistic individuals, including sensory hyperreactivity (i.e., strong reactions to sensory input), hyporeactivity (i.e., no, or slower reactions to sensory input), and seeking (i.e., fascination or fixation with sensory input). Sensory hyperreactivity can be particularly distressing and has previously been linked to anxiety in autism, and intolerance of uncertainty (IU) has been suggested to be an interlinking transdiagnostic construct. However, limited research has included sensory hyporeactivity or seeking, or examined links to certain anxiety symptomology, and research in young children and adults is especially lacking. Therefore, the four studies presented in this thesis had the primary aim of 1) elucidating the relationship between sensory reactivity difference and anxiety symptomology in autistic individuals, and secondary aims of 2) understanding the role of IU in this relationship, and 3) understanding more about the sensory experiences of autistic adults. The first study examined the relationship between sensory reactivity differences and anxiety in autistic children ages 3 – 14 years; the second study examined the relationship between sensory reactivity differences, anxiety, and IU in preschool-age autistic children ages 3 – 5 years; the third pair of studies examined the relationship between sensory reactivity differences, anxiety, and IU in autistic adults ages 18+ years; and the final study, examined the sensory experiences of autistic adults using a coproduced, mixed-methods approach. The findings robustly support an association between sensory hyperreactivity and anxiety symptomology in autistic individuals, and most notably, a consistent relationship across studies with separation anxiety. Furthermore, IU was found to be a mediating factor associated with anxiety and sensory hyperreactivity in children and adults. Although sensory hyporeactivity and seeking were linked with anxiety in some studies, this was not consistent across the studies. The findings from the mixed methods study provided enriched insights into the findings in this thesis from the perspective of autistic adults and highlighted the complex nature of sensory reactivity differences. This informed the creation of an enhanced model, which could further guide future directions. Overall, the results in this thesis advance understanding of the relationship between sensory reactivity differences and anxiety symptomology. Understanding the risk factors for anxiety in autism has importance for the development and adaptation of effective interventions for autistic children and adults.

description: The interplay between frustration and quantum fluctuation in magnetic systems is known to be the origin of many exotic states in condensed matter physics. In this paper, we consider a frustrated four-leg spin tube under a magnetic field. This system is a prototype to study the emergence of a nonmagnetic ground state factorizable into local states and the associated order parameter without quantum fluctuation, that appears in a wide variety of frustrated systems. The one-dimensional nature of the system allows us to apply various techniques: a path-integral formulation based on the notion of order by disorder, strong-coupling analysis where magnetic excitations are gapped, and density-matrix renormalization group. All methods point toward an interesting property of the ground state in the magnetization plateaus, namely, a quantized value of relative magnetizations between different sublattices (spin imbalance) and an almost perfect factorization of the ground state.
Characterizing ICME-related Forbush Decreases at Mercury using MESSENGER Observations: Identification of a One or Two-Step Structure

description: The large-scale magnetic structure of interplanetary coronal mass ejections (ICMEs) has been shown to cause decreases in the galactic cosmic ray (GCR) flux measured in situ by spacecraft, known as Forbush decreases (Fds). We use measurements of the GCR count rate obtained by MESSENGER during its orbital phase around Mercury to identify such Fds related to the passage of ICMEs and characterize their structure. Of the 42 ICMEs with corresponding high-quality GCR data, 79% are associated with a Fd. Thus a total of 33 ICME-related Fds were identified, 24 of which (73%) have a two-step structure. We use a superposed epoch analysis to build an average Fd profile at MESSENGER and find that despite the variability of individual events, a two-step structure is produced and is directly linked with the magnetic boundaries of the ICME. By using results from previous studies at Earth and Mars, we also address whether two-step Fds are more commonly observed closer to the Sun; we found that although likely, this is not conclusive when comparing to the wide range of results of previous studies conducted at Earth. Finally, we find that the percentage decrease in GCR flux of the Fd is greater at MESSENGER on average than at Earth and Mars, decreasing with increasing heliocentric distance. The relationship between the percentage decrease and maximum hourly decrease is also in agreement with previous studies, and follows trends relating to the expansion of ICMEs as they propagate through the heliosphere.

description: Physics education research (PER) is a rapidly growing area of PhD specialization. In this article we examine the trajectories that led respondents into a PER graduate program as well as their expected future trajectories. Data were collected in the form of an online survey sent to graduate students in PER. Our findings show a lack of visibility of PER as a field of study, a dominance of work at the undergraduate level, and a mismatch of future desires and expectations. We suggest that greater exposure is needed so PER is known as a field of inquiry for graduates, that more emphasis should be placed on research beyond the undergraduate level, and that there needs to be stronger communication to graduate students about potential careers.

description: In this work, we numerically investigate the scattering and absorption cross section of the massless scalar field from some well-known regular black holes by using the partial wave approach. Our computational results indicate that the larger the parameters, the lower the associated total absorption cross section maxima. When compared to the Schwarzschild black hole, the scattering cross section is enhanced in some regular black hole spacetimes, meanwhile the scattering width is narrow in the forward orientation. Moreover, it is found that the null geodesics of the critical impact parameter and the geometrical optical value in the high frequency regime have similar changing behavior.

Estimates of heterogeneity (I2) can be biased in small meta-analyses

description: In meta-analysis, the fraction of variance that is due to heterogeneity is known as I2. We show that the usual estimator of I2 is biased. The bias is largest when a meta-analysis has few studies and little heterogeneity. For example, with 7 studies and the true value of I2 at 0, the average estimate of I2 is .124. Estimates of I2 should be interpreted cautiously when the meta-analysis is small and the null hypothesis of homogeneity (I2=0) has not been rejected. In small meta-analyses, confidence intervals may be preferable to point estimates for I2.

description: Il profilo sierico, con particolare riferimento ai livelli di biomarkers, rappresenta uno strumento efficace ed affidabile per la diagnosi di malattie metaboliche, come il diabete o le malattie cardiovascolari. La composizione del siero è influenzata sia dal metabolismo endogeno che dall’apporto nutrizionale. In effetti, lo stile alimentare, con particolare riferimento alla qualità e alla quantità dell’apporto nutrizionale, può fortemente influenzare il rischio e la progressione di malattia, poiché alcuni nutrienti agiscono come composti bioattivi. A questo proposito, la letteratura attuale indica un importante ruolo di specifiche molecole nutrizionali provenienti dalla dieta che interessano specifiche vie metaboliche. L'obiettivo del nostro progetto è quello di individuare pathways metabolici regolati da nutrienti, con lo scopo di identificare possibili taget terapeutici in stati patologici. [ a cura dell'autore]

description: Since 2013, the MASA (Mémoire des Archéologues et des Sites Archéologiques) consortium of the TGIR Huma-Num has assisted archaeologists in digitising and making available their excavation archives, as well as disseminating the FAIR principles within the French archaeological community. The goal is to help archaeologists make their data interoperable and open up their datasets on the semantic web, by using the CIDOC CRM ontology as a shared structure layer for their heterogeneous data. OpenArchaeo is a platform which attempts to achieve this goal by describing the data with a generic model using a subset of the CIDOC CRM and some extensions (CRMsci, CRMarchaeo and CRMba), as well as few gazetteers and standard vocabularies (PACTOLS, GeoNames, VIAF, ORCID). With this modelisation, the commonalities of the heterogeneous datasets are described with the same structure and metadata. The generic model describes some archeological main concepts and their relationship with each other, such as archeological site, artefact, documentation, etc.

description: Feedback traps use closed-loop control to trap or manipulate small particles and molecules in solution. They have been applied to the measurement of physical and chemical properties of particles and to explore fundamental questions in the non-equilibrium statistical mechanics of small systems. These applications have been hampered by drifts in the electric forces used to manipulate the particles. Although the drifts are small for measurements on the order of seconds, they dominate on time scales of minutes or slower. Here, we show that an extended recursive least-squares (RLS) parameter-estimation algorithm can allow real-time measurement and control of electric and stochastic forces over time scales of hours. Simulations show that the extended-RLS algorithm recovers known parameters accurately. Experimental estimates of diffusion coefficients are also consistent with expected physical properties.

description: "Changing-look active galactic nuclei" (CLAGNs) are known to change their apparent types between types 1 and 2, usually accompanied by a drastic change in their luminosity on timescales of years. However, it is still unclear whether materials in broad-line regions (BLRs) in CLAGNs appear and disappear during the type-transition or remain at the same location while the line production is simply activated or deactivated. Here we present our X-ray-optical monitoring results of a CLAGN, NGC 3516, by Suzaku, Swift, and ground telescopes, with our primary focus on the narrow Fe-K$α$ emission line, which is an effective probe of the BLR materials. We detected significant variations of the narrow Fe-K$α$ line on a timescale of tens of days during the type-2 (faint) phase in 2013-2014, and conducted "narrow Fe-K$α$ reverberation mapping," comparing its flux variation with those of the X-ray continuum from a corona and $B$-band continuum from an accretion disk. We derived, as a result, a time lag of $10.1^{+5.8}_{-5.6}$ days ($1σ$ errors) for the Fe-K$α$ line behind the continuum, which is consistent with the location of the BLR determined in optical spectroscopic reverberation mapping during the type-1 (bright) phase. This finding shows that the BLR materials remained at the same location without emitting optical broad-lines during the type-2 phase. Considering the drastic decrease of the radiation during the type-transition, our result is possibly inconsistent with the hotly-discussed formation models of the BLR which propose that the radiative pressure from an accretion disk should be the main driving force.

description: We study the Fourier time-lags due to the Comptonization of disc-emitted photons in a spherical, uniform, and stationary X-ray corona, which located on the rotational axis of the black hole. We use Monk, a general relativistic Monte-Carlo radiative transfer code, to calculate Compton scattering of photons emitted by a thin disc with a Novikov-Thorne temperature profile. We find that the model time-lags due to Comptonization remain constant up to a characteristic frequency and then rapidly decrease to zero at higher frequencies. We provide equations which can be used to determine the time-lags and cross spectra for a wide range of values for the corona radius, temperature, optical depth, height, and for various accretion rates and black hole masses. We also provide an equation for the X-ray luminosity of a single corona, as a function of the its characteristics and location above the disc. Remarkably, the observed X-ray time-lags of nearby, bright active galaxies can be successfully reproduced by inverse Comptonization process of multiple dynamic coronae.

description: Turbulence in protoplanetary disks plays an important role in dust evolution and planetesimal formation. The vertical shear instability (VSI) is one of the candidate hydrodynamic mechanisms that can generate turbulence in the outer disk regions. The VSI requires rapid gas cooling in addition to vertical shear. A linear stability analysis suggests that the VSI may not operate around the midplane where gas cooling is inefficient. In this study, we investigate the nonlinear outcome of the VSI in disks with a linearly VSI-stable midplane region. We perform two-dimensional global hydrodynamical simulations of an axisymmetric disk with vertically varying cooling times. The vertical cooling time profile determines the thicknesses of the linearly VSI-stable midplane layer and unstable layers above and below the midplane. We find that the thickness of the midplane stable layer determines the vertical structure of VSI-driven turbulence in the nonlinear saturated state. We identify two types of final saturated state: (1) T states characterized by vertical turbulent motion penetrating into the VSI-stable midplane layer and (2) pT states characterized by turbulent motion confined in the unstable layers. The pT states are realized when the midplane VSI-stable layer is thicker than two gas scale heights. We also find that the VSI-driven turbulence is largely suppressed at all heights when the VSI-unstable region lying above and below the midplane is thinner than two gas scale heights. We present empirical formulas that predict the strength of VSI-driven turbulence as a function of the thicknesses of the unstable and stable layers. These formulas will be useful for studying how VSI-driven turbulence and dust grains controlling the disk cooling efficiency evolve simultaneously.

description: We compute four-derivative corrections to the AdS supergravity actions arising from the near-horizon geometry of N M5-branes wrapped on either one or two Riemann surfaces. This setup features the novel presence of both gauged isometries as well as nontrivial hypermultiplets. We argue that the 5d Chern-Simons terms receive not only higher-derivative corrections but also contributions from Killing vector parameters, which we find must also be corrected. We check the central charges found by our supergravity methods against the dual field theory results and find perfect agreement at leading and subleading order in N. Along the way, we find higher derivative corrections to general AdS_5 and AdS_3xΣ_g geometries.

description: Ο εργασιακός χώρος κατακλύζεται από συναισθηματικές αντιδράσεις και επιδράσεις. Η παρούσα έρευνα, επεκτείνοντας προηγούμενες έρευνες και ανιχνεύοντας τις πηγές των συναισθημάτων των εργαζομένων, ελέγχει υποθέσεις, που αφορούν τις σχέσεις της ρύθμισης συναισθήματος και των πτυχών της συναισθηματικής νοημοσύνης του ηγέτη, με το συναίσθημα και τη στάση των υφισταμένων στην εργασία, ελέγχοντας ταυτόχρονα την επίδραση της συνοχής της ομάδας. Ταυτόχρονα ελέγχει τη σχέση της ρύθμισης συναισθήματος και των πτυχών της συναισθηματικής νοημοσύνης των ηγετών και των υφισταμένων, με την εργασιακή τους εμπειρία. Το δείγμα αποτελούνταν από 51 διευθυντές σχολείων και 281 εκπαιδευτικούς, οι οποίοι συμπλήρωσαν ερωτηματολόγια αυτοαναφοράς, που αφορούσαν τη ρύθμιση συναισθήματος, τις τέσσερις αυταναφερόμενες πτυχές της ΣΝ, το θετικό και αρνητικό συναίσθημα, τη συνοχή της ομάδας, την επαγγελματική ικανοποίηση και την αντίληψη για τη σχέση συναλλαγής μεταξύ υφισταμένου και προϊσταμένου. Αντίθετα με τις αρχικές υποθέσεις, η πολυεπίπεδη ανάλυση δεν έδειξε σχέση μεταξύ των πτυχών της συναισθηματικής νοημοσύνης του ηγέτη και της εργασιακής εμπειρίας των υφισταμένων. Ενώ, η ρύθμιση συναισθήματος του ηγέτη, παρουσίασε αρνητική συσχέτιση με την επαγγελματική ικανοποίηση και το συναίσθημα στην εργασία των υφισταμένων. Στην μονοεπίπεδη ανάλυση διάφορες πτυχές της συναισθηματικής νοημοσύνης των ηγετών και των εκπαιδευτικών είχαν θετική συσχέτιση με τη στάση και το εργασιακό συναίσθημα των ίδιων. Αυτά τα πορίσματα ερμηνεύονται μέσα από μία κοινωνικο-αλληλεπιδραστική προοπτική η οποία τονίζει τη σχέση συναλλαγής που αναπτύσσεται μεταξύ ηγέτη και υφισταμένου και συνεισφέρει σε μία κατανόηση της επίδρασης των συναισθημάτων είτε ενδοατομικά και διαπροσωπικά.

description: Το παιδικό εικονογραφημένο βιβλίο, του οποίου η επιρροή στο σχηματισμό της προσωπικότητας είναι αναμφίβολη (Καρπόζηλου, 1994), μιας και μέσω αυτού μεταφέρονται ιδεολογίες και αντιλήψεις για τον κόσμο (Sipe, 1999), χρησιμοποιείται συχνά στην εκπαιδευτική διαδικασία. Η διαπολιτισμική λογοτεχνία, συγκεκριμένα, φέρνει σε επαφή το παιδί με οικογένειες, πολιτισμούς και περιβάλλοντα, τα οποία είναι κατά κάποιο τρόπο παρόμοια ή διαφορετικά από τα δικά του (Holland, 2005), επίσης βοηθά τα παιδιά να αναπτύξουν την αίσθηση της ταυτότητας, κατανοώντας με αυτόν τον τρόπο τις διαφορές τους από τους άλλους, τους προσφέρονται γνώσεις για τον δικό τους και για τους άλλους πολιτισμούς και ικανότητες στο να μπορούν να σχετίζονται αποτελεσματικά με άτομα από διαφορετικά πολιτιστικά περιβάλλοντα (Bosma, 1995). Βέβαια, πριν την χρησιμοποίηση της θα πρέπει να εξετάζεται και να αξιολογείται (Μαραθευτής, 1990). Στη συγκεκριμένη έρευνα έγινε μία προσπάθεια, με τη βοήθεια πέντε διαπολιτισμικών βιβλίων, καταγραφής των αντιλήψεων και στάσεων των παιδιών απέναντι στην ετερότητα, αλλά και των κριτηρίων με τα οποία επιλέγουν ένα βιβλίο. Επίσης, συγκρίθηκαν οι λόγοι των επιλογών των παιδιών με κριτήρια, που έχουν ήδη τεθεί από ειδικούς ερευνητές. Τα αποτελέσματα έδειξαν ότι τα παιδιά χρησιμοποιούν τα δικά τους κριτήρια για την επιλογή των βιβλίων και ότι οι αντιλήψεις τους επηρεάζονται από τα «κατάλληλα» και «μη κατάλληλα» βιβλία. Οι εικόνες, ο τρόπος παρουσίασης των ηρώων, η πλοκή της ιστορίας είναι ορισμένα από τα στοιχεία που διαμορφώνουν τις επιλογές τους.

description: This document intends to provide an update to the Dissemination and Communication Strategy. The structure of the document has not changed. The main parts of the previous contents are still present, but a series of new considerations have been added on the basis of the feedback received last year. Following the previous version of the document, this updated version has a strong and concrete approach, based on the practical experience gained in the first three years of the project’s implementation. On the basis of the results reached, the main objective of this document is thus to realistically maintain the same level of the communication and dissemination activities implemented until now.

description: In this paper we first introduce the extended limit set $J_{\{T^n\}}(x)$ for a sequence of bounded linear operators $\{T_n\}_{n=1}^{\infty}$ on a separable Banach space $X$ . Then we study the dynamics of sequence of linear operators by using the extended limit set. It is shown that the extended limit set is strongly related to the topologically transitive of a sequence of linear operators. Finally we show that a sequence of operators $\{T_n\}_{n=1}^{\infty}\subseteq \mathcal{B}(X)$ is hypercyclic if and only if there exists a cyclic vector $x\in X$ such that $J_{\{T^n\}}(x)=X$.

description: Synthesis is the automatic construction of a system from its specification. In classical synthesis algorithms, it is always assumed that the system is "constructed from scratch" rather than composed from reusable components. This, of course, rarely happens in real life, where almost every non-trivial commercial software system relies heavily on using libraries of reusable components. Furthermore, other contexts, such as web-service orchestration, can be modeled as synthesis of a system from a library of components. Recently, Lustig and Vardi introduced dataflow and control-flow synthesis from libraries of reusable components. They proved that dataflow synthesis is undecidable, while control-flow synthesis is decidable. In this work, we consider the problem of control-flow synthesis from libraries of probabilistic components . We show that this more general problem is also decidable.

description: We study the dynamics of parallel brane-brane and brane-antibrane scattering in string theory in flat spacetime, focusing on the pair production of open strings that stretch between the branes. We are particularly interested in the case of scattering at small impact parameter $b < l_s$, where there is a tachyon in the spectrum when a brane and an antibrane approach within a string length. Our conclusion is that despite the tachyon, branes and antibranes can pass through each other with only a very small probability of annihilating, so long as $g_s$ is small and the relative velocity $v$ is neither too small nor too close to 1. Our analysis is relevant also to the case of charged open string production in world-volume electric fields, and we make use of this T-dual scenario in our analysis. We briefly discuss the application of our results to a stringy model of inflation involving moving branes.
