description: A theoretical description of the differential decay spectrum for the decay tau- -> nu_tau K_S pi-, which is based on the contributing K pi vector and scalar form factors F_+^{K pi}(s) and F_0^{K pi}(s) being calculated in the framework of resonance chiral theory (R$χ$T), additionally imposing constraints from dispersion relations as well as short distance QCD, provides a good representation of a recent measurement of the spectrum by the Belle collaboration. Our fit allows to deduce the total branching fraction B[tau- -> nu_tau K_S pi-] = 0.427 +- 0.024 % by integrating the spectrum, as well as the K^* resonance parameters M_{K^*} = 895.3 +- 0.2 MeV and Gamma_{K^*} = 47.5 +- 0.4 MeV, where the last two errors are statistical only. From our fits, we confirm that the scalar form factor F_0^{K pi}(s) is required to provide a good description, but we were unable to further constrain this contribution. Finally, from our results for the vector form factor F_+^{K pi}(s), we update the corresponding slope and curvature parameters lambda'_+ = (25.2 +- 0.3)*10^{-3} and lambda''_+ = (12.9 +- 0.3)*10^{-4}, respectively.

description: Instructors have limited time and resources to help struggling students, and these resources should be directed to the students who most need them. To address this, researchers have constructed models that can predict students' final course performance early in a semester. However, many predictive models are limited to static and generic student features (e.g. demographics, GPA), rather than computing-specific evidence that assesses a student's progress in class. Many programming environments now capture complete time-stamped records of students' actions during programming. In this work, we leverage this rich, fine-grained log data to build a model to predict student course outcomes. From the log data, we extract patterns of behaviors that are predictive of students' success using an approach called differential sequence mining. We evaluate our approach on a dataset from 106 students in a block-based, introductory programming course. The patterns extracted from our approach can predict final programming performance with 79% accuracy using only the first programming assignment, outperforming two baseline methods. In addition, we show that the patterns are interpretable and correspond to concrete, effective -- and ineffective -- novice programming behaviors. We also discuss these patterns and their implications for classroom instruction.

We study two temperature correlators from the total free energy and from the domain wall free energy: in the second case we detect a chaotic behavior. We determine and discuss the chaos exponent and the fractal dimension of the domain walls.

Biased Cosmology: Pivots, Parameters, and Figures of Merit

description: In the quest for precision cosmology, one must ensure that the cosmology is accurate as well. We discuss figures of merit for determining from observations whether the dark energy is a cosmological constant or dynamical, with special attention to the best determined equation of state value, at the ``pivot'' or decorrelation redshift. We show this is not necessarily the best lever on testing consistency with the cosmological constant, and moreover is subject to bias. The standard parametrization of w(a)=w_0+w_a(1-a) by contrast is quite robust, as tested by extensions to higher order parametrizations and modified gravity. Combination of complementary probes gives strong immunization against inaccurate, but precise, cosmology.

description: We in this paper study theoretically the spin-polarized quantum transport through a T-shape quantum dot-array by means of transfer-matrix method along with the Green^{,}s function technique. Multi-magnetic fields are used to produce the spin-polarized transmission probabilities and therefore the spin currents, which are shown to be tunable in a wide range by adjusting the energy, and the direction-angle of magnetic fields as well. Particularly the opposite- spin- polarization currents separately flowing out to two electrodes can be generated and thus the system acts as a spin splitter.

Για την αποτίμηση της αποτελεσματικότητας του μοντέλου πειραματιστήκαμε με 2 σύνολα δεδομένων, ένα μικρό της τάξης των 21.000 εικόνων και ένα μεγαλύτερο με 800.000 εικόνες, χρησιμοποιώντας απομακρυσμένη επίβλεψη για την παραγωγή ενός χαρακτηρισμένου συνόλου δοκιμής
description: This thesis is about bio-medical image classification. Our goal was to train a machine learning model that assigns Unified Medical Language System concepts to bio-medical images using semi-supervised learning techniques. We experimented with an algorithm that does not need a labelled dataset but uses distant supervision to label each image based on its caption. Since finding data is one of the biggest problems in machine learning, we took advantage of the open access to biomedical texts provided by PubMed, from which we extracted images and their captions. To evaluate the performance of our model, we experimented with 2 datasets, one with 21.000 images and one with 800.000, using distant supervision to produce a test set

description: Radial flow can be directly extracted from the azimuthal distribution of mean transverse rapidity. We apply the event-plane method and the two-particle correlation method to estimate the anisotropic Fourier coefficient of the azimuthal distribution of mean transverse rapidity. Using the event sample generated by a multiphase transport model with string melting, we show that both methods are effective. For the two-particle correlation method to be reliable, the mean number of particles in an azimuthal bin must be above a certain threshold. Using these two methods, anisotropic radial flow can be estimated in a model-independent way in relativistic heavy-ion collisions.

description: We calculate the energy-momentum tensor due to electromagnetic vacuum fluctuations between two parallel hyperplanes in more than four dimensions, considering both metallic and MIT boundary conditions. Using the axial gauge, the problem can be mapped upon the corresponding problem with a massless, scalar field satisfying respectively Dirichlet or Neumann boundary conditions. The pressure between the plates is constant while the energy density is found to diverge at the boundaries when there are extra dimensions. This can be related to the fact that Maxwell theory is then no longer conformally invariant. A similar behavior is known for the scalar field where a constant energy density consistent with the pressure can be obtained by improving the energy-momentum tensor with the Huggins term. This is not possible for the Maxwell field. However, the change in the energy-momentum tensor with distance between boundaries is finite in all cases.

Refocusing on Gender: Can Focal Concerns Theory Explain Gender Disparities in Sentencing Outcomes?

description: Focal concerns theory argues that sentencing decisions reflect judges' beliefs about three primary considerations: blameworthiness of the defendant, protection of the community, and practical concerns. This perspective has been used as the theoretical foundation in an abundance of research and has proven particularly useful as a framework for explaining sentencing disparities related to offenders' demographic characteristics. Little work, however, has been able to incorporate perceptual measures of the three focal concerns into studies of sentencing outcomes and social inequality. This study uses a dataset that combines official county court records with case-level judicial surveys to conduct a more direct test of the focal concerns theory of judicial decision-making. It measures judicial assessments of each focal concern for each court case and then evaluates the extent to which these assessments explain gender disparities in two sentencing decisions: the decision to incarcerate, and the determination of sentence length.

description: We present the results of near-infrared imaging and spectroscopic observations of the young, core-collapse supernova remnant (SNR) G11.2-0.3. In the [Fe II] 1.644 um image, we first discover long, clumpy [Fe II] filaments within the radio shell of the SNR, together with some faint, knotty features in the interior of the remnant. We have detected several [Fe II] lines and HI Br-G line toward the peak position of the bright southeastern [Fe II] filament. The derived extinction is large (Av=13 mag) and it is the brightest [Fe II] filament detected toward SNRs to date. By analyzing two [Fe II] 1.644 um images obtained in 2.2 yrs apart, we detect a proper motion corresponding to an expansion rate of 0.''035 (0.''013) /yr [or 830 (310) km/s]. We also discover two small H2 filaments. One is bright and along the SE boundary of the radio shell, while the other is faint and just outside of its NE boundary. We have detected H2 (2-1) S(3) line toward the former filament and derive an excitation temperature of 2,100 K. We suggest that the H2 filaments are dense clumps in a presupernova circumstellar wind swept up by the SNR shock while the [Fe II] filaments are probably composed of both shocked wind material and shocked supernova (SN) ejecta. The distribution of [Fe II] filaments may indicate that the SN explosion in G11.2-0.3 was asymmetric as in Cassiopeia A. Our results support the suggestion that G11.2-0.3 is a remnant of a SN IIL/b interacting with a dense red supergiant wind.

description: The IR Spectra Simulator is a complete educational discovery-based environment for enhancing reading, interpreting and exploiting skills in real IR spectra. It includes a set of manuals with guiding instructions and additional exercises in Greek as well as in English. After they practise on the simulator, the students will have gained a solid methodology for identifying unknown organic compounds given their IR spectrum. Its aim is to provide an additional tool for teaching IR spectroscopy, by offering an opportunity for interaction with a real IR spectrum and hands-on experience. This tool does not replace the experiment, the book or the teacher. This software can be used in distance learning, beyond its simple application within the laboratory under the teacher’s guidance, since its target group is students with basic chemistry and physics knowledge

description: Resistive switching devices, important for emerging memory and neuromorphic applications, face significant challenges related to control of delicate filamentary states in the oxide material. As a device switches, its rapid conductivity change is involved in a positive feedback process that would lead to runaway destruction of the cell without current, voltage, or energy limitation. Typically, cells are directly patterned on MOS transistors to limit the current, but this approach is very restrictive as the necessary integration limits the materials available as well as the fabrication cycle time. In this article we propose an external circuit to cycle resistive memory cells, capturing the full transfer curves while driving the cells in such a way to suppress runaway transitions. Using this circuit, we demonstrate the acquisition of $10^5$ I-V loops per second without the use of on-wafer current limiting transistors. This setup brings voltage sweeping measurements to a relevant timescale for applications, and enables many new experimental possibilities for device evaluation in a statistical context.

For a dilute gas of such vortices, the lowest energy \textit{fermionic} eigenstates are intrinsically non-local. We predict two testable signatures of this unusual quantum non-locality in quasiparticle tunneling experiments. We discuss why the associated teleportation-like phenomenon does not imply the violation of causality.

description: Modern change detection (CD) has achieved remarkable success by the powerful discriminative ability of deep convolutions. However, high-resolution remote sensing CD remains challenging due to the complexity of objects in the scene. Objects with the same semantic concept may show distinct spectral characteristics at different times and spatial locations. Most recent CD pipelines using pure convolutions are still struggling to relate long-range concepts in space-time. Non-local self-attention approaches show promising performance via modeling dense relations among pixels, yet are computationally inefficient. Here, we propose a bitemporal image transformer (BIT) to efficiently and effectively model contexts within the spatial-temporal domain. Our intuition is that the high-level concepts of the change of interest can be represented by a few visual words, i.e., semantic tokens. To achieve this, we express the bitemporal image into a few tokens, and use a transformer encoder to model contexts in the compact token-based space-time. The learned context-rich tokens are then feedback to the pixel-space for refining the original features via a transformer decoder. We incorporate BIT in a deep feature differencing-based CD framework. Extensive experiments on three CD datasets demonstrate the effectiveness and efficiency of the proposed method. Notably, our BIT-based model significantly outperforms the purely convolutional baseline using only 3 times lower computational costs and model parameters. Based on a naive backbone (ResNet18) without sophisticated structures (e.g., FPN, UNet), our model surpasses several state-of-the-art CD methods, including better than four recent attention-based methods in terms of efficiency and accuracy. Our code is available at https://github.com/justchenhao/BIT\_CD.

I Miracoli di Buzzati tra scrittura e pittura

description: L’analisi dell’opera doppia I Miracoli di Valmorel di Dino Buzzati, intesa come il miglior esito della sua produzione pittorica e letteraria, ha permesso una riflessione sulle possibilità espressive e combinatorie dei testi visivo e verbale e sulla negoziazione delle frontiere tra i due media.

Il racconto a cornice dell’opera ricostruisce l’antefatto della creazione artistica: l’immaginario  ritrovamento di alcune tavole di ex voto, in un santuario dedicato a Santa Rita in Val Morel, fornisce l’occasione per riprodurre i 39 dipinti che nell’edizione iconotestuale vengono accompagnati da altrettanti micro-racconti dello stesso autore.

Le combinazioni che Buzzati produce, per giustapposizione (iconotesto) e per simbiosi (iconismo),  offrono una varietà esemplare delle relazioni possibili tra letteratura e pittura. La frontiera istituzionale della pagina, che separa la parola dall’immagine, si sposta all’interno della tavola (nel caso di iscrizioni, cartigli o didascalie) oppure si dissolve completamente dando luogo a un vero e proprio iconismo. Gli esempi proposti illustrano come la presenza o l’assenza delle frontiere che i due linguaggi negoziano è frutto di una complessa strategia di veridizione che coinvolge voce narrante, referente e senso nei due testi.
 L’analisi ha permesso inoltre di avviare una riflessione sulle potenzialità metanarrativa e metapittorica dell’iconotesto.

Involvement of British Columbia community pharmacists in health promotion

Year: 2009

description: Community pharmacists are faced with many opportunities to participate in health promotion. The purpose of this study was to determine the extent to which community pharmacists in British Columbia are involved in health promotion activities, and which external factors, if any, affect this level of involvement. A causal model was developed which proposed that independent pharmacist and practice variables would influence pharmacists' involvement in health promotion activities. A five- page mail questionnaire was distributed to a systematic stratified sample of 625 practising community pharmacists in British Columbia. A five-point Likert-type scale was used to examine the frequencies of pharmacist involvement in 33 different health promotion activities. Three different follow-up procedures were used to attain a final response rate of 83.6%. Results of the study show that pharmacists most frequently participate in activities that are related directly to the dispensing or selling of medications. These events include advising clients on over-the-counter medications, querying clients on possible allergies, obtaining medical histories, querying clients on current medications, and suggesting non-drug alternatives to drug therapy for minor ailments. The activities that displayed the lowest participation amongst pharmacists included speaking to community groups on health related matters, participating in disease screening programs, querying clients on their level of occupational stress, counselling clients on AIDS prevention, and querying clients on their smoking status. Variables that were found to influence a pharmacist's level of participation in health promotion were a pharmacist's employment status (full-time or part-time), marital status, type of practice, geographic location of the practice, pharmacist's personal health beliefs and behaviours, and the socioeconomic status of the clientele predominantly served.

description: The merger of two supermassive black holes is expected to produce a gravitational-wave signal detectable by the satellite LISA. The rate of supermassive-black-hole mergers is intimately connected to the halo merger rate, and the extended Press-Schechter formalism is often employed when calculating the rate at which these events will be observed by LISA. This merger theory is flawed and provides two rates for the merging of the same pair of haloes. We show that the two predictions for the LISA supermassive-black-hole-merger event rate from extended Press-Schechter merger theory are nearly equal because mergers between haloes of similar masses dominate the event rate. An alternative merger rate may be obtained by inverting the Smoluchowski coagulation equation to find the merger rate that preserves the Press-Schechter halo abundance, but these rates are only available for power-law power spectra. We compare the LISA event rates derived from the extended Press-Schechter merger formalism to those derived from the merger rates obtained from the coagulation equation and find that the extended Press-Schechter LISA event rates are thirty percent higher for a power spectrum spectral index that approximates the full Lambda-CDM result of the extended Press-Schechter theory.

The main goal of an effective supply chain is the achievement of the desirable level of service with the minimum possible quantity level. This will finally lead to the achievement of profits and the creation of a financial scale for the company. The minimization of the cost which is achieved with the reduction of stock items should be done in a way which will not affect the product's availability. The purpose of this task is to calculate the minimum necessary number of three of the products that a great worldwide company in the field of commodity produces (Olympic brewery has). The model that will be used is the Economic Production Lot Size Model and the purpose is to calculate the requested amount of production which will bring the minimum possible stock and without affecting the product's availability

It is found that two attempts to pursue the development of a regional system of suburban centres have been unsuccessful, while a municipally-based policy has achieved some success in terms of the physical design of a suburban downtown. Patterns of private sector development are found to have been very little affected by any of the case study policies. Further, several assumptions concerning the linkages between public transit and land use in suburban centres are found to require further careful examination before they should be used as a basis for future policy development.

description: The purpose of this diploma thesis is the financial analysis of five major Greek companies belonging to the sector of companies dealing with Renewable Energy Sources (Renewable Energy Sources) and especially those specializing in photovoltaic systems. In the first part of the paper a historical review of the photovoltaic systems will be made, their mode of operation, the categories that are distinguished, their advantages and disadvantages, the evolution and presence of PV systems in our country, as well as the prospects they may have in the Greek market. Next, we present the five companies that we will deal with in this paper. Also, the financial analysis of the five companies for the years 2012, 2013, 2014, 2015 will be carried out through the financial statements of the companies prepared in accordance with the International Accounting Standards (IAS). Finally, we will produce some results that will be based on the indicators we have calculated, and we will then be able to arrive at safe conclusions about their future course and viability as well as the prospects for their development

description: Many stars evolve into magnetic white dwarfs, and observations may help to understand when the magnetic field appears at the stellar surface, if and how it evolves during the cooling phase, and what are the mechanisms that generate it. After obtaining new spectropolarimetric observations and combining them with previous literature data, we have checked the population of about 152 white dwarfs within 20 pc from the Sun for the presence of magnetic fields, with a sensitivity that ranges from better than 1 kG for most of the stars of spectral class DA, to 1 MG for some of the featureless white dwarfs. We find that 33 white dwarfs of the local 20 pc volume are magnetic. Statistically the data are consistent with the possibility that the frequency of the magnetic field occurrence is similar in stars of all spectral classes, except that in the local 20 pc volume, either DQ stars are more frequently magnetic, or host much stronger fields than average. The distribution of the observed field strength ranges from 40 kG to 300 MG and is uniform per decade, in striking contrast to the field frequency distribution resulting from spectroscopic surveys. No fields weaker than 40 kG are found. We confirm that magnetic fields are more frequent in white dwarfs with higher than average mass. We find a marked deficiency of magnetic white dwarfs younger than 0.5 Gyr, and that the frequency of the occurrence of the magnetic field is significantly higher in white dwarfs that have undergone the process of core crystallisation than in white dwarfs with fully liquid core. There is no obvious evidence of field strength decay with time. We discuss the implications of our findings in relation to some of the proposals that have been put forward to explain the origin and evolution of magnetic fields in degenerate stars, in particular those that predict the presence of a dynamo acting during the crystallisation phase.

description: We study S- and P-wave pion-pion and kaon-pion distributions for the three-body production processes $J/ψ\toωπ^{+}π^{-}$, $D^{+}\to K^{-}π^{+}π^{+}$, $D^{+}\to K^{+}π^{+}π^{-}$, and $D^{+}_{s}\to K^{+}π^{+}π^{-}$, by applying the Resonance-Spectrum Expansion to the two-body subamplitudes. The results are compared to the corresponding signals reported by the BES, E791 and FOCUS collaborations. We find that the studied S- and P-wave channels can largely account for the observed structures in the data up to 1 GeV.

description: We study how much the unique ability of the OPERA experiment to directly detect ν_τcan help in probing new, non-standard contact interactions of the third family of neutrinos. We perform a combined analysis of future, high-statistics MINOS and OPERA data. For the case of non-standard interactions in ν_μto ν_e transitions we also include the impact of possible DoubleCHOOZ data. In all cases we find that the ν_τsample of OPERA is too small to be statistically significant, even if one doubles the nominal exposure of OPERA to 4.5E20 pot. OPERA's real benefit for this measurement lies in its very high neutrino energy and hence very different L/E compared to MINOS.

Classical statistical distributions can violate Bell-type inequalities

description: We investigate two-particle phase-space distributions in classical mechanics characterized by a well-defined value of the total angular momentum. We construct phase-space averages of observables related to the projection of the particles' angular momenta along axes with different orientations. It is shown that for certain observables, the correlation function violates Bell's inequality. The key to the violation resides in choosing observables impeding the realization of the counterfactual event that plays a prominent role in the derivation of the inequalities. This situation can have statistical (detection related) or dynamical (interaction related) underpinnings, but non-locality does not play any role.

description: We investigate whether there could exist topological invariants of gapped 2D materials related to dissipationless thermoelectric transport at low temperatures. We give both macroscopic and microscopic arguments showing that thermoelectric transport coefficients vanish in the limit of zero temperature and thus topological invariants arise only from the electric Hall conductance and the thermal Hall conductance. Our arguments apply to systems with arbitrarily strong interactions. We also show that there is no analog of the Thouless pump for entropy.

description: Στην παρούσα εργασία μελετήθηκε ο αποπολυμερισμός του μίγματος PET/PLA ως πρότυπα πολυμερή. Η αντίδραση που πραγματοποιήθηκε ήταν η υδρολυτική αποικοδόμηση του μίγματος σε αλκαλικό περιβάλλον και με ακτινοβόληση με μικροκύματα. Σκοπός της παρούσας εργασίας ήταν να διαπιστωθεί κατά πόσον μπορεί η χρήση των μικροκυμάτων να συντομεύσει τον χρόνο της αντίδρασης, να μειώσει τις απαιτήσεις σε ενέργεια και /ή να αυξήσει την απόδοσή της. Οι παράμετροι της αντίδρασης που μελετήθηκαν ήταν η επίδραση της θερμοκρασίας, η επίδραση της ισχύος των μικροκυμάτων, η παρουσία/απουσία καταλύτη και ο βαθμός αλκαλικότητας του διαλύματος. Το υπόλειμμα που παραλήφθηκε μετά το τέλος της αντίδρασης ταυτοποιήθηκε με φασματοσκοπία TGA και το σημείο υαλώδους μετάβασης μετρήθηκε μέσω της διαφορικής σαρωτικής θερμιδομετρίας. Τα αποτελέσματα έδειξαν ότι η χρήση των μικροκυμάτων συντομεύει κατά πολύ τον απαιτούμενο χρόνο για την ολοκλήρωση της αντίδρασης. Επίσης, η μέθοδος αποφαίνεται σύμφωνη με τις αρχές της πράσινης χημείας καθώς επιτυγχάνει αρκετά καλά αποτελέσματα χωρίς τη χρήση μεγάλων ποσοτήτων αντιδραστηρίων και τοξικών διαλυτών
description: In the present study, the polymerization of the PET / PLA mixture as standard polymers was studied. The reaction was hydrolytic degradation of the mixture in alkaline environment and microwave irradiation. The purpose of this work was to determine whether microwave use can shorten the reaction time, reduce energy demand and / or increase performance. The reaction parameters studied were the influence of temperature, the effect of microwave power, the presence / absence of catalyst and the degree of alkalinity of the solution. The residue obtained after the end of the reaction was identified by TGA spectroscopy and the glass transition point was measured by differential scanning calorimetry. The results showed that the use of microwaves greatly shortens the time required to complete the reaction. The method also decides according to the principles of green chemistry as it achieves quite good results without the use of large quantities of reagents and toxic solvents
