description: Η παρούσα διπλωματική εργασία, με θέμα τα «Ολοκληρωμένα συστήματα διαχείρισης στις μικρομεσαίες επιχειρήσεις», εκπονήθηκε στα πλαίσια του διατμηματικού προγράμματος μεταπτυχιακών σπουδών «Πληροφορική και Διοίκηση», των τμημάτων Πληροφορικής και Οικονομικών Επιστημών, του Αριστοτελείου Πανεπιστημίου Θεσσαλονίκης. Στοχεύει στην παρουσίαση των συστημάτων διαχείρισης που εφαρμόζονται στις μέρες μας από τις μικρομεσαίες επιχειρήσεις. Τα συστήματα αυτά σκοπό έχουν την καλύτερη εξυπηρέτηση των πελατών, την εξοικονόμηση χρόνου και πόρων και την όσο το δυνατόν καλύτερη αξιοποίηση των δυνατοτήτων των επιχειρήσεων. Για το λόγο αυτό έγινε μελέτη και αξιολόγηση των ολοκληρωμένων συστημάτων διαχείρισης (διαχείρισης ποιότητας, περιβαλλοντικής διαχείρισης, υγιεινής και ασφάλειας των εργαζομένων) προκειμένου να ερευνηθεί η χρησιμότητά τους τόσο σε θεωρητικό όσο και σε πρακτικό επίπεδο. Η εργασία χωρίζεται σε δύο μέρη. Στο πρώτο μέρος, πραγματοποιείται μια θεωρητική προσέγγιση των Ολοκληρωμένων συστημάτων διαχείρισης και στο δεύτερο μέρος πραγματοποιείται μια ποσοτική έρευνα για τη μελέτη της κατάστασης που επικρατεί στις Ελληνικές μικρομεσαίες επιχειρήσεις.
description: The present diplomatic with the subject of «Integrated Management Systems in Small-Medium enterprises» was worked out for the interdepartmental program of postgraduate course on «Informatics and Management » by the departments of Informatics and Economics of the Aristotle University of Thessaloniki. The goal of this study is to inform about the management systems that are used nowadays from the small-medium enterprises. Integrated management systems are used to give better services to costumers, for saving time and recourses and for the better as possible exploitation of enterprises skills. For this reason, was made a research and the evaluation of the Integrated Management Systems (quality, environmental, health and safety) in order to search about their use in theoretical and in practical level. The research is divided into two parts. In the first part, is a theoretical approach of Integrated Management Systems and in the second part it is a quantitative search about the study of situation of that systems in Greek small-medium enterprises.

description: We examine the relic density of the light mass dark matter region in the inert doublet model (IDM) when the dominant process is due to co-annihilation between the lightest neutral scalars of the model. The full one-loop electroweak corrections are computed in an on-shell scheme and are found to be well approximated as an effective cross-section expressed in terms of $Z$-observables. The electroweak corrections to the subdominant process which consists of an annihilation into an on-shell $W$ and an off-shell $W$, that is calculated as a annihilation into a 3-body final state, is also performed. The latter reveals an important dependence on a parameter that describes the self-interaction of the new scalars (solely within the dark sector), a parameter which is not accessible in tree-level calculations of standard model (SM)-IDM interactions.

description: Η εργασία αυτή ασχολείται με την ανάπτυξη και την υλοποίηση (σε γλώσσα προγραμματισμού C++) ενός μυωπικού αλγορίθμου για την επίλυση του προβλήματος της βέλτιστης κατανομής των αποθηκευτικών χώρων των συστημάτων παραγωγής με στόχο την αύξηση της απόδοσής τους. Ο προτεινόμενος αλγόριθμος δημιουργήθηκε στηριζόμενος στη βασική ιδέα των μυωπικών αλγορίθμων και συνεργάζεται με την εκτιμητική μέθοδο που αναπτύχθηκε από τους Diamantidis, Heavey και Papadopoulos (2005) για τον υπολογισμό της απόδοσης των λύσεων. Η συγκεκριμένη υλοποίηση του αλγορίθμου έχει τη δυνατότητα να λύνει προβλήματα σε συστήματα παραγωγής με σειριακές γραμμές παραγωγής, με παράλληλες μηχανές στα κέντρα επεξεργασίας και με διαφορετικό χρόνο επεξεργασίας ανά κέντρο. Μεγάλος αριθμός διαφόρων πειραμάτων διεξήχθησαν σε μικρές, μεσαίες και μεγάλες γραμμές παραγωγής έως 200 σταθμούς εργασίας και συγκρίθηκαν τα αποτελέσματά του με άλλους αλγορίθμους από τη διεθνή βιβλιογραφία. Τα αποτελέσματά του ήταν αρκετά ικανοποιητικά αλλά όχι τα βέλτιστα σε όλες τις περιπτώσεις.
description: This work deals with the development and implementation (in programming language C++) of a myopic algorithm for the resolution of the buffer allocation problem in industrial systems with the intention to increase their output. The proposed algorithm was created based on the central idea of myopic algorithms and it cooperates with the estimative function proposed by Diamantidis, Heavey and Papadopoulos (2005). The particular implementation of the algorithm deals with industrial systems with serial production lines, parallel machines and different rate per work station. Numerous experiments were carried out in small, medium and big serial production lines until 200 stations of work and the results were compared with other algorithms from the international literature. The results were enough satisfactory but not the best in the all cases.

description: The current requirements suggest the need for the education and the training of adults. This need not be perceived by everyone to the same extent. This event has turned the attention of this research to investigate the factors that determine the participation of a portion of people in activities of Continuing Edu-cation. More specifically focus on Professional Teachers of secondary school. The study is divided into two parts. The first is a bibliography research of re-search efforts relating to the participation of adults in educational activities and registration of theories concerning the interpretation and prediction of the phe-nomenon of participation. The second part presents an empirical investigation in which attempts to shape the profile of teachers participating in Continuing Edu-cation and the exploration of the factors that have led them to participate. The picture of these factors is quite rich. As the most important factors are emerging those of professional development and personal development.
On the Importance of the Azimuth Offset in a Combined 1P and 2P SISO IPC Implementation for Wind Turbine Fatigue Load Reductions

description: Wind turbines experience periodic loads causing fatigue damage to blades and structural parts. The application of individual pitch control (IPC) using the multi-blade coordinate (MBC) transformation enables the attenuation of these loads. Often, the transformed fixed-frame load signals are subject to a single-input single-output controller design. However, the coupling between the transformed fixed-frame axes increases for higher load harmonics, increased actuator phase lag, and larger rotors with more flexible blades, posing a need for multivariable controller designs or decoupling strategies. It has been shown earlier that the coupling for the 1P harmonic is minimized by introduction of an azimuth offset in the MBC transformation. This paper extends the previous work and demonstrates the consequences and importance of including the azimuth offset for mitigation of higher load harmonics. A multivariable sensitivity and fatigue load analysis is performed using different pitch actuator models. Results from high-fidelity simulations show near-perfect attenuation of 1P and 2P periodic loads by including the azimuth offset, whereas by excluding the offset, the performance worsens with respect to the baseline case without IPC.

description: The literary journals during the Greek Occupation (1941-1944) have a special position in the history of Greek Literature, not only for the circumstances under which they came out in public but especially because of the new spirit they introduced at the literature of that period. From their pages the novelists and poets of the First Post-war Generation were born. The subject of this thesis is a journal, Ksekinima, that had been published the last year of the Greek Occupation, 1944, form Thessaloniki’s Cultural Group of the Aristotle University. Placed in the group of the youth journals that were been publishing in that years, given that to his editors were young students of the Aristotle University of Thesssaloniki, Ksekinima possess a special significance for the city’s spiritual life as much as for the country’s. The purpose of that thesis is the promotion of his special place and his relation with the literary frame of that era.

description: We perform the first one-loop electroweak corrections for $2 \to 3$ processes for dark matter annihilation. These are the dominant processes that enter the computation of the relic density for the low mass region of the inert doublet model (IDM) when annihilations to two on-shell vector bosons are closed. The impact of the one-loop corrections are important as they involve, through rescattering effects, not only a dependence on the parameter controlling the dark sector, not present if a calculation at tree-level is conducted, but also on the renormalisation scale. These combined effects should be taken into account in analyses based on tree-level cross-sections of the relic density calculations, as a theoretical uncertainty which we find to be much larger than the cursory $\pm 10\%$ uncertainty that is routinely assumed, independently of the model parameters.

Analysing Long Short Term Memory Models for Cricket Match Outcome Prediction

Subjects: subject: Machine Learning (cs.LG)

description: As the technology advances, an ample amount of data is collected in sports with the help of advanced sensors. Sports Analytics is the study of this data to provide a constructive advantage to the team and its players. The game of international cricket is popular all across the globe. Recently, various machine learning techniques have been used to analyse the cricket match data and predict the match outcome as win or lose. Generally these models make use of the overall match level statistics such as teams, venue, average run rate, win margin, etc to predict the match results before the beginning of the match. However, very few works provide insights based on the ball-by-ball level statistics. Here we propose a novel Recurrent Neural Network model which can predict the win probability of a match at regular intervals given the ball-by-ball statistics. The Long Short Term Memory (LSTM) Model takes as input the ball wise features as well as the match level details available from the training dataset. It gives a prediction of winning the match at any time stamp during the match. This level of insight will help the team to predict the probability of them winning the match after every ball and help them determine the critical in-game changes they should make in their game strategies.
Using ordinary multiplication to do relativistic velocity addition

description: Relativistic addition of velocities in one dimension, though a mainstay of introductory physics, contributes much less physical insight than it could. For such calculations, we propose the use of velocity factors (two-way doppler factors). Velocities can easily, often by inspection, be turned into velocity factors, and vice versa. Velocity factors compose by ordinary multiplication. This simple device considerably extends the kinds of questions that can be asked and answered in an introductory course.

Consciousness as a logically consistent and prognostic model of reality

description: The work demonstrates that brain might reflect the external world causal relationships in the form of a logically consistent and prognostic model of reality, which shows up as consciousness. The paper analyses and solves the problem of statistical ambiguity and provides a formal model of causal relationships as probabilistic maximally specific rules. We suppose that brain makes all possible inferences from causal relationships. We prove that the suggested formal model has a property of an unambiguous inference: from consistent premises we infer a consistent conclusion. It enables a set of all inferences to form a consistent model of the perceived world. Causal relationships may create fixed points of cyclic inter-predictable properties. We consider the "natural" classification introduced by John St. Mill and demonstrate that a variety of fixed points of the objects' attributes forms a "natural" classification of the external world. Then we consider notions of "natural" categories and causal models of categories, introduced by Eleanor Rosch and Bob Rehder and demonstrate that fixed points of causal relationships between objects attributes, which we perceive, formalize these notions. If the "natural" classification describes the objects of the external world, and "natural" concepts the perception of these objects, then the theory of integrated information, introduced by G. Tononi, describes the information processes of the brain for "natural" concepts formation that reflects the "natural" classification. We argue that integrated information provides high accuracy of the objects identification. A computer-based experiment is provided that illustrates fixed points formation for coded digits.

description: Local Binary Patterns (LBP) are extensively used to analyze local texture features of an image. Several new extensions to LBP-based texture descriptors have been proposed, focusing on improving noise robustness by using different coding or thresholding schemes. In this paper we propose three algorithms (LBP), Shift Local Binary Pattern (SLBP), and Multi Shift Local Binary Pattern (MSLBP),to extract features for palmprint images that help to obtain the best unique and characteristic values of an image for identification. The Principal Component Analysis (PCA) algorithm has been applied to reduce the size of the extracted feature matrix in random space and in the matching process; the Linear Discriminant Analysis (LDA) algorithm is used. Several experiments were conducted on the large multispectral database (blue, green, red, and infrared) of the University of Hong Kong. As result, distinguished and high results were obtained where it was proved that, the blue spectrum is superior to all spectra perfectly.

description: In this article we compare a variety of well known dynamical dark energy models using the cosmic microwave background measurements from the 2018 Planck legacy and 2015 Planck data releases, the baryon acoustic oscillations measurements and the local measurements of $H_0$ obtained by the SH0ES (Supernovae, $H_0$, for the Equation of State of Dark energy) collaboration analysing the Hubble Space Telescope data. We discuss the alleviation of $H_0$ tension, that is obtained at the price of a phantom-like dark energy equation of state. We perform a Bayesian evidence analysis to quantify the improvement of the fit, finding that all the dark energy models considered in this work are preferred against the $Λ$CDM scenario. Finally, among all the possibilities analyzed, the CPL model is the best one in fitting the data and solving the $H_0$ tension at the same time. However, unfortunately, this dynamical dark energy solution is not supported by the baryon acoustic oscillations (BAO) data, and the tension is restored when BAO data are included for all the models.

description: The contact dynamics method (CD) is an efficient simulation technique of dense granular media where unilateral and frictional contact problems for a large number of rigid bodies have to be solved. In this paper we present a modified version of the contact dynamics to generate homogeneous random packings of rigid grains. CD is coupled to an external pressure bath, which allows the variation of the size of a periodically repeated cell. We follow the concept of the Andersen dynamics and show how it can be applied within the framework of the contact dynamics method. The main challenge here is to handle the interparticle interactions properly, which are based on constraint forces in CD. We implement the proposed algorithm, perform test simulations and investigate the properties of the final packings.

Abolition and William Blake’s illustrations for Stedman’s Expedition against the revolted Negroes of Surinam
Creators: name: Andrews, Sharon Andrea
Publisher: name: University of British Columbia
Year: 2009

description: In 1796, John Gabriel Stedman's "Narrative of a Five Years Expedition against the Revolted Negroes of Surinam" was published in London. The "Expedition" described Stedman's campaigns as a mercenary officer employed by the Dutch colony of Surinam. Stedman, subscribing to eighteenth-century notions of empiricism, described in great detail the flora, fauna and inhabitants of Surinam, including the brutal mistreatment of its plantation slaves. However, while calling for amelioration of such mistreatment, Stedman stated his support for slavery as a system and for the cross-Atlantic slave trade. Eighty-one illustrations, by various engravers, accompanied the Expedition and received contemporary acclaim. Of those, twelve images of slaves and slave life including illustrations that represent the punishment and execution of slaves, were engraved by William Blake. These latter images were unusual within the traditions of book illustrations in travel narratives and abolitionist literature because of their graphic display of pain. This thesis focuses on Blake's illustrations and in particular assesses the way in which these images contributed to the late eighteenth-century reception of Stedman's publication as a document that supported abolition and antislavery interests. Both William Blake and the publisher of the Expedition. Joseph Johnson belonged to "radical" groups that advocated the ending of both slavery and the slave trade. This thesis argues that Blake, supported by Johnson, emphasized abolitionist and antislavery elements in the illustrations thereby allowing the publication to be harnessed to the cause of the anti-slave trade movement. In order to examine Blake's illustrations within the Expedition the thesis is divided into four sections: Chapter One assesses the rise of the abolition movement in late eighteenth-century Britain; Chapter Two contextualizes the Stedman images within the traditions of travel and abolitionist literature; Chapter Three examines eighteenth-century printing and engraving practises; and Chapter Four assesses the images themselves and the way they could work both with and at times against Stedman's text.

description: In the past, there have been many studies claiming that the effects of geomagnetic storms strongly depends on the orientation of the magnetic-cloud part of the Coronal Mass Ejections (CMEs). Aparna & Martens (2020), using Halo-CME data from 2007-2017, have shown that the magnetic field orientation of filaments at the location where CMEs originate can be effectively used for predicting the onset of geo-magnetic storms. The purpose of this study is to extend their survey by analyzing the halo-CME data for 1996-2006. The correlation of filament axial direction and their corresponding Bz signatures are used to form a more extensive reasoning for the claims presented by Aparna & Martens before. This study utilizes SOHO EIT 195 Å, MDI magnetogram images, KSO and BBSO H$α$ images for the time period, along with ACE data for inter-planetary magnetic field signatures. Correlating all these, we have found that the trend in Aparna & Martens' study of a high likelihood of the correlation between the axial field direction and Bz orientation, persists for the data between 1996-2006 as well.

A model for the incongruent dissolution of pyrite
Creators: name: Irwin, Keith Wayne
Publisher: name: University of British Columbia
Year: 2009

description: To understand the incongrucnt dissolution phase of natural pyrite, polished and cleaned samples were subjected to oxidative dissolution at low pH from 0 to 72 hours. All samples were operationally defined as pure based on XRD, XRF, SEM/EDXA and XPS analyses. At 12 hour intervals, one pyrite sample and 10 mLs of solution were extracted from the reaction vessel for analysis. The air-sensitive pyrite samples were introduced into the UHV of an x-ray photoelectron spectrometer. Iron (Fe 2p) and sulfur (S 2p) oxidation states were measured and S/Fe mole ratios were calculated. All samples were compared to a series of controls which indicated the Fe 2p and S 2p binding energies to be 706.7 eV and 162.4 eV respectively. The reference S/Fe ratio was found to be 3.6. This high ratio is believed to be indicative of a natural weathering rind. Curve fitting indicated the presence of elemental sulfur in small amounts (7%), whereas, most sulfur retained its pyritic form. Throughout the dissolution experiment, both photoemission peaks showed no significant signs of oxidation despite the presence of oxygen at the surface. The S/Fe ratio increased from 3.6 to 5.6 (t = 48 h) after which point the ratio decreased rapidly to its original value. The 10 mL aliquot of solution was partitioned into two sub-aliquots - one for the determination of total iron by atomic absorption, the other for total sulfate by nephelometry, a method which proved itself to be superior to the more conventional turbidimetric method. Solution phase data indicated the relatively constant production rate of iron until 48 hours at which point, there is a noticeable increase in this rate. Sulfate analysis indicated a similar trend to that of iron though the increased rate at 48 hours was dramatic. Based on a correlation of the surface data with that of the solution phase, the following mechanism was proposed. Iron diffuses along a S/Fe mole ratio gradient. Eventually, a critical ratio is achieved at which time the surface begins to crumble. Flakes of elemental sulfur and sulfur-rich pyrite detach from the surface. The elemental sulfur is thought to remain as such based on the findings cited in the literature review. Given the significant rise in the production rate of sulfate, the sulfur-rich pyrite flakes are believed lo convert quickly to sulfate while simultaneously releasing iron into solution.

description: We provide support for the claim that momentum is conserved for individual events in the electron double slit experiment. The natural consequence is that a physical mechanism is responsible for this momentum exchange, but that even if the fundamental mechanism is known for electron crystal diffraction and the Kapitza-Dirac effect, it is unknown for electron diffraction from nano-fabricated double slits. Work towards a proposed explanation in terms of particle trajectories affected by a vacuum field is discussed. The contentious use of trajectories is discussed within the context of oil droplet analogues of double slit diffraction.

description: Η παρούσα εργασία πραγματεύεται αφενός την έννοια, το σκοπό και τη διάκριση των απολύτων ακυροτήτων από άλλες διαδικαστικές πράξεις και αφετέρου τον χρόνο, τον τρόπο προβολής τους και τις συνέπειες που συνεπάγονται. Βάσει των υποπεριπτώσεων του άρθρου 171 του Κώδικα Ποινικής Δικονομίας διερευνώνται οι ακυρότητες που συνήθως ανακύπτουν στην εξέλιξη της ποινικής δίκης, ο τρόπος που τις αντιμετωπίζει η νομολογία και η κριτική που ασκεί σ’ αυτήν η επιστήμη.
description: The present dissertation studies the definition and the purpose of absolute invalidities and its’ differentiation from other procedural acts. In addition it analyses the way they are propounded and their consequences. Based on the sub-clauses of article 171 of the Criminal Procedure Rules this study considers the most frequently occurring invalidities, the way they are applied by case-law, and the relevant scientific criticism.

Τα συμβαλλόμενα μέρη έχουν τη δυνατότητα να επιλέξουν το δίκαιο που θα διέπει τη σχέση τους, ενώ σε περίπτωση που δε γίνει αυτό η σχέση τους θα διέπεται κατά σειρά από το δίκαιο του τόπου όπου παρέχει ο εργαζόμενος την εργασία του, ο τόπος εγκατάστασης της επιχείρησης που τον προσέλαβε ή τέλος από το δίκαιο με το οποίο συνδέεται στενότερα η σύμβαση.

description: The applicable law in individual labor agreements is now set in countries - members of the European Union from the Regulation 593/2008 (article 8). The covenanter parts have the right to choose the applicable law that will regulate their relations, whereas, in cases where this does not occur, their relation will be determined first by the local law of the place where an employee works, second, by the law regulating the business establishment which hired this employee or, eventually, by the law that is connected most closely to the agreement. Very critical is the role attributed by the Regulation to the rules of obligatory right, that ensure the most fitting conditions for the workers even in the predominant provisions of obligatory right (article 9) that are always applied, whichever the applicable law is in order to guarantee exceptional government owned interests. Also significant is the reserve of the judge’s public order (article 21).

description: Resolvent analysis identifies the most responsive forcings and most receptive states of a dynamical system, in an input--output sense, based on its governing equations. Interest in the method has continued to grow during the past decade due to its potential to reveal structures in turbulent flows, to guide sensor/actuator placement, and for flow control applications. However, resolvent analysis requires access to high-fidelity numerical solvers to produce the linearized dynamics operator. In this work, we develop a purely data-driven algorithm to perform resolvent analysis to obtain the leading forcing and response modes, without recourse to the governing equations, but instead based on snapshots of the transient evolution of linearly stable flows. The formulation of our method follows from two established facts: $1)$ dynamic mode decomposition can approximate eigenvalues and eigenvectors of the underlying operator governing the evolution of a system from measurement data, and $2)$ a projection of the resolvent operator onto an invariant subspace can be built from this learned eigendecomposition. We demonstrate the method on numerical data of the linearized complex Ginzburg--Landau equation and of three-dimensional transitional channel flow, and discuss data requirements. The ability to perform resolvent analysis in a completely equation-free and adjoint-free manner will play a significant role in lowering the barrier of entry to resolvent research and applications.

description: Globular star clusters contain thousands to millions of old stars packed within a region only tens of light years across. Their high stellar densities make it very probable that their member stars will interact or collide. There has been considerable debate about whether black holes should exist in these star clusters. Some theoretical work suggests that dynamical processes in the densest inner regions of globular clusters may lead to the formation of black holes of ~1,000 solar masses. Other numerical simulations instead predict that stellar interactions will eject most or all black holes that form in globular clusters. Here we report the X-ray signature of an accreting black hole in a spectroscopically-confirmed globular cluster in the Virgo Cluster giant elliptical galaxy NGC 4472. This object has an X-ray luminosity of about 4*10^39 ergs/sec, making it brighter than any non-black hole object can be in an old stellar population. The X-ray luminosity varies by a factor of 7 in a few hours, ruling out the possibility that the object is several neutron stars superposed.

Conceptual Mutation Testing for Student Programming Misconceptions

description: Context: Students often misunderstand programming problem descriptions. This can lead them to solve the wrong problem, which creates frustration, obstructs learning, and imperils grades. Researchers have found that students can be made to better understand the problem by writing examples before they start programming. These examples are checked against correct and wrong implementations -- analogous to mutation testing -- provided by course staff. Doing so results in better student understanding of the problem as well as better test suites to accompany the program, both of which are desirable educational outcomes.
 Inquiry: Producing mutant implementations requires care. If there are too many, or they are too obscure, students will end up spending a lot of time on an unproductive task and also become frustrated. Instead, we want a small number of mutants that each correspond to common problem misconceptions. This paper presents a workflow with partial automation to produce mutants of this form which, notably, are not those produced by mutation-testing tools.
 Approach: We comb through student tests that fail a correct implementation. The student misconceptions are embedded in these failures. We then use methods to semantically cluster these failures. These clusters are then translated into conceptual mutants. These can then be run against student data to determine whether we they are better than prior methods. Some of these processes also enjoy automation.
 Knowledge: We find that student misconceptions illustrated by failing tests can be operationalized by the above process. The resulting mutants do much better at identifying student misconceptions.
 Grounding: Our findings are grounded in a manual analysis of student examples and a quantitative evaluation of both our clustering techniques and our process for making conceptual mutants. The clustering evaluation compares against a ground truth using standard cluster-correspondence measures, while the mutant evaluation examines how conceptual mutants perform against student data.
 Importance: Our work contributes a workflow, with some automation, to reduce the cost and increase the effectiveness of generating conceptually interesting mutants. Such mutants can both improve learning outcomes and reduce student frustration, leading to better educational outcomes. In the process, we also identify a variation of mutation testing not commonly discussed in the software literature.
The effect of detachment and attachment to a kink motion in the asymmetric simple exclusion process

description: We study the dynamics of a kink in a one-lane asymmetric simple exclusion process with detachment and attachment of the particle at arbitrary sites. For a system with one site of detachment and attachment we find that the kink is trapped by the site, and the probability distribution of the kink position is described by the overdumped Fokker-Planck equation with a V-shaped potential. Our results can be applied to the motion of a kink in arbitrary number of sites where detachment and attachment take place. When detachment and attachment take place at every site, we confirm that the kink motion obeys the diffusion in a harmonic potential. We compare our results with the Monte Carlo simulation, and check the quantitative validity of our theoretical prediction of the diffusion constant and the potential form.

description: We present electric dipole polarizabilities ($α_d$) of the alkali-metal negative ions, from H$^-$ to Fr$^-$, by employing four-component relativistic many-body methods. Differences in the results are shown by considering Dirac-Coulomb (DC) Hamiltonian, DC Hamiltonian with the Breit interaction, and DC Hamiltonian with the lower-order quantum electrodynamics interactions. At first, these interactions are included self-consistently in the Dirac-Hartree-Fock (DHF) method, and then electron correlation effects are incorporated over the DHF wave functions in the second-order many-body perturbation theory, random phase approximation and coupled-cluster (CC) theory. Roles of electron correlation effects and relativistic corrections are analyzed using the above many-body methods with size of the ions. We finally quote precise values of $α_d$ of the above negative ions by estimating uncertainties to the CC results, and compare them with other calculations wherever available.

description: Extraction of the mass spectrum from twisted mass lattice QCD is facilitated by respecting the octahedral group of rotations and accommodating the broken parity and flavor symmetries of the theory. In this work, group theory meson operators adapted to these constraints are constructed for the special case of quark and antiquark fields at a common lattice site, connected by extended gauge field paths.

An X-ray and SZ bright diffuse source toward M31: a Local Hot Bridge

description: We report a large-scale ($r\approx 20^\circ$) X-ray and Sunyaev-Zeldovich (SZ)-bright diffuse enhancement toward M31, which might be a Local Hot Bridge connecting the Milky Way (MW) with M31. We subtract the Galactic emission from the all-sky O VII and O VIII emission line measurement survey, and find that the emission of these two ions is enhanced within $r\approx20^\circ$ around M31. The mean emission enhancements are $5.6\pm 1.3$ L.U., and $2.8\pm0.6$ L.U. for O VII and O VIII, respectively ($>4σ$ for both ions). We also extract the SZ signal around M31, which suggests a surface brightness $y$ of $2-4\times10^{-7}$, an enhancement $>2.5σ$ (and a best fit of $5.9σ$). These three measurements trace the hot gas with a temperature $\log~T({\rm K})> 6$, showing similar plateau shapes (flat within $\approx15^\circ$, and zero beyond $\approx30^\circ$). A single-phase assumption leads to a temperature of $\log~T({\rm K})=6.34\pm0.03$, which is determined by the O VII/O VIII line ratio. Combining X-ray and SZ measurements, we suggest that this feature is unlikely to be the hot halo around M31 (too massive) or in the MW (too high pressure and X-ray bright). The plateau shape may be explained by a cylinder connecting the MW and M31 (the Local Hot Bridge). We constrain its length to be about 400 kpc, with a radius of 120 kpc, a density of $\approx 2\times10^{-4}-10^{-3} ~\rm cm^{-3}$, and a metallicity of $0.02-0.1~ Z_\odot$. The baryon mass is $\gtrsim10^{11}~M_\odot$, and the oxygen mass is about $\gtrsim10^8~M_\odot$, which contribute to the baryon or metal budget of the Local Group.
