description: We present a simple method for the calculation of reaction rates in the Fermi golden-rule limit, which accurately captures the effects of tunnelling and zero-point energy. The method is based on a modification of the recently proposed golden-rule quantum transition state theory (GR-QTST) of Thapa, Fang and Richardson. While GR-QTST is not size consistent, leading to the possibility of unbounded errors in the rate, our modified method has no such issue and so can be reliably applied to condensed phase systems. Both methods involve path-integral sampling in a constrained ensemble; the two methods differ, however, in the choice of constraint functional. We demonstrate numerically that our modified method is as accurate as GR-QTST for the one-dimensional model considered by Thapa and coworkers. We then study a multi-dimensional spin-boson model, for which our method accurately predicts the true quantum rate, while GR-QTST breaks down with an increasing number of boson modes in the discretisation of the spectral density. Our method is able to accurately predict reaction rates in the Marcus inverted regime, without the need for the analytic continuation required by Wolynes theory.

description: Το θέατρο του Ζαν Ταρντιέ, με αφετηρία τις προσωπικές του εμπειρίες και αναζητήσεις, προσεγγίζει θέματα κοσμικά και αποκτά μια οικουμενική διάσταση. Τα σύντομα θεατρικά του, των οποίων το θέμα είναι συχνά η πράξη της γραφής και τα γλωσσικά προβλήματα, εκφράζουν την επιθυμία του συγγραφέα τους να αμφισβητήσει τις θεατρικές συμβάσεις τις οποίες θεωρούσε ξεπερασμένες, και να εξερευνήσει τις δυνατότητες του θεάτρου, συμβάλλοντας έτσι στην ανανέωση και την εξέλιξή του, ακολουθώντας το παράδειγμα της μουσικής και της ζωγραφικής. Ο κόσμος των έργων του κυριαρχείται από το όνειρο που εισβάλλει στη σκηνή μέσα από μία σειρά αντιθέσεων εμπνευσμένων από την προσωπική εμπειρία του δραματουργού, και ανατρέπει την πραγματικότητα αλλά και τη δομή των θεατρικών. Πλήθος προσώπων, ήχων, φωνών, μουσικής και εικόνων μεταφέρει στον θεατή το μυστήριο της ανθρώπινης ύπαρξης και επιφυλάσσει για το δραματουργό μια ιδιαίτερη θέση σ'αυτό που συνηθίζουμε να ονομάζουμε θέατρο του παραλόγου.
description: Jean Tardieu's theater inspired by his personal experiences, borders on cosmic items and acquires a universal dimension. His short plays, whose the subject is frequently the writing and the language problems, express the writer's desire to contest the dramatic conventions which he considers impoverished, to explore the possibilities of theater and to contribute in this way to its renewal following the example of music and painting. The world of his plays is dominated by the dream which invades the scene through the contradictions based on the writer's personal experience, and reverses their structure and the reality. Persons, sounds, voices, music and images communicate to the spectator the mystery of the human being and reserve for the playwright a special place among the authors of the Theater of Absurd.

description: In the high-viscosity borosilicate glass (NBS2) doped with 0.3 mol% CoO or NiO quenching resulted in a freeze-in snap-shot of the glass structure within the dopants' transformation process from their high-temperature tetrahedral coordination to the octahedral form normally present in this glass at room temperature. In this transitional state the octahedral, tetrahedral and a third pseudotetrahedral transitional coordination are simultaneously present. The optical spectra of the doped glasses are discussed in relation to the different melting and cooling conditions applied. Quenched glasses were also tempered on a heating table, which permitted to take the optical spectra at each temperature step. In contrast to Co2+, Ni2+ has a strong octahedral preference. Thus for NiO-doped NBS2 glass tempering or annealing always results in relaxation into the octahedral coordination. For Co2+, which is also octahedrally coordinated in the annealed NBS2, tempering of the quenched glass leads to a relaxation into octahedrally and tetrahedrally coordinated Co2+. These structural changes are especially strong when the applied temperatures lie 150 to 200 °C above Tg of the NBS2 glass where also the viscosity-temperature curve implies structural changes within the glass matrix.

Atomic force microscope study of the topography of float glasses and a model to explain the bloom effect

description: The topography and nanostructure of several technical borofloat and soda-lime-silicate float glasses were investigated by a high-resolution atomic force microscope (AFM). The irregular ripple pattern to be seen on as-received atmosphere and tin bath side surfaces had an average diameter of ≈ 60 nm, heights < 1 nm and root mean square (rms) roughnesses on (1 × 1) µm2 images of < 0.25 nm. Topographies obtained in the mirror region of fracture surfaces displayed a somewhat coarser nanostructure. It could further be assured that there are no specific differences between the interior and the edge of the float glass sample. Inhomogeneities like precipitates, crystals, phase separation or pores are not caused by the in-diffusion of tin into the float glass. After annealing the float glasses in air, several of them showed the already long known phenomenon of bloom, a greyish haze produced by a wrinkling of the tin bath glass surface. The borofloat glasses did not produce bloom under any condition. The same was true for the Fe2O3-rich green and blue glasses. Depending on sample dimensions and annealing conditions only the Fe2O3-poor clear float glasses developed a pronounced bloom effect. It is known that annealing of the glasses in air causes an oxidation of Sn2+ to Sn4+, which acts as a network former. This causes a change in glass properties near the surface. However, the precisely measured in-depth profiles of all relevant species in the nanometer and the micrometer regions of the float glasses showed that only in the ease of the Fe2O3-poor silicate float glasses a reversed Sn2+ diffusion from the interior to the surface is caused by the air annealing, forming a very high and steep tin (Sn4+) enrichment in a superficial layer with a thickness between 50 and 150 nm. In analogy to thin film technology a simplified model was developed and a free buckling length of ≈ 2.3 µm was estimated for the bloom surface, which is in reasonable agreement with the experimental finding. It was further shown that a sol-gel derived SiO2 coating of the bloom surface could enhance the optical transmission of the glass considerably.

description: A study was undertaken on how to prepare frit reference materials in which the following elements are analysed: Si, Al, Fe, Ca, Mg, N, K, Ti , Zr, Ba, Pb, Zn, Hf, P, B and Li . The following analytical techniques were used: X-ray fluorescence spectrometry (XRF), inductively coupled plasma optical emission spectrometry (ICP-OES), atomic absorption spectrophotometry (AAS) and titrimetry. Boron and lithium were analysed by ICP OES, sodium and lithium by AAS, and boron by titrimetry, while the remaining frit elements and sodium were analysed by XRF. The results found by the different methods were compared and each method was validated by means of reference materials. A procedure was established for preparing frit reference materials for calibrating and validating working methods on an industrial scale.

description: Οι απόψεις του K. Popper παρουσιάζουν κοινά σημεία με αυτές των φιλοσόφων του Κύκλου της Βιέννης. Είναι εμπειριστής, αρνείται όμως την εγκυρότητα της μεταφυσικής γνώσης, μολονότι τη θεωρεί αφορμή για τη διατύπωση επιστημωνικών θεωριών. Καταφεύγει στην επαγωγική μέθοδο και ορίζει τη διαψευσιμότητα σαν κριτήριο του εμπειρικού χαρακτήρα των επιστημονικών προτάσεων. Επίσης, προσεγγίζει το χαρακτήρα της επιστημονικής γνώσης μέσα από ορθολογιστική σκέψη. Ο T. Kuhn, από την άλλη, πρότεινε μια νέα εικόνα της επιστήμης μέσα από το έργο του "Δομή των Επιστημονικών Επαναστάσεων". Διατύπωσε τρεις φάσεις της ανάπτυξης των επιστημών καθώς και μια νέα επιστημονική ορολογία με σημαντικότερους όρους το "παράδειγμα" και την "Κανονική Επιστήμη". Αργότερα όρισε σαν κυριότερη συνέπεια μιας επιστημονικής επανάστασης την αλλαγή της σημασίας των όρων των θεωριών, χωρίς να αναθεωρήσει ριζικά τις απόψεις του. Προσπάθησε επίσης να βρει τη λύση ορισμένων επιστημονικών προβλημάτων. Γενικά ο Popper επιχείρησε να ανασκευάσει το θετικισμό και τον θεμελιακό χαρακτήρα της γνώσης και ο Kuhn του άσκησε κριτική εγκανιάζοντας νέους δρόμους στην επιστημολογία και προωθώντας την αυτονομία των επιστημονικών γνώσεων κάθε περιόδου.
description: The views of K. Popper have some characteristics common to the views of the philosopher's of the circle of Vienna. Popper is empiristic but he denies the validity of the metaphysical knowledge, although he believes that it is the cause of the formulation of scientific theories. He uses the epagogical method and he marks the fasibility as the criterion of the empirical character of the scientific sentences. He approaches also the character of the scientific knowledge through a rationalistic thought. T. Kuhn, in the other side, suggested a new picture of the science through his work "The structure of Scientific Theories". He expressed three periods of the development of the sciences and a new scientific terminology, which has as most famous terms the "example" and the "Normal Science". Later he definided as the most significant consequence of the scientific revolution the change of the meanings of the terms of the theories without revising radically his views. He tried also to find the solution of some scientific problems. Generally Popper tried to rearrange the theticism and the fundamental character of the knowledge and Kuhn criticised him inaugurating new epistemological directions and promoting the autonomy of the epistemological knowledges every period.

description: The tin-selenide and tin-sulfide classes of materials undergo multiple structural transitions under high pressure leading to periodic lattice distortions, superconductivity, and topologically non-trivial phases, yet a number of controversies exist regarding the structural transformations in these systems. We perform first-principles calculations within the framework of density functional theory and a careful comparison of our results with available experiments on SnSe$_2$ reveals that the apparent contradictions among high-pressure results can be attributed to differences in experimental conditions. We further demonstrate that under hydrostatic pressure a $\sqrt{3} \times \sqrt{3} \times 1$ superstructure can be stabilized above 20 GPa in SnS$_2$ via a periodic lattice distortion as found recently in the case of SnSe$_2$, and that this pressure-induced phase transition is due to the combined effect of Fermi surface nesting and electron-phonon coupling at a momentum wave vector $\mathbf{q}$ = $(1/3, 1/3, 0)$. In addition, we investigate the contribution of nonadiabatic corrections on the calculated phonon frequencies, and show that the quantitative agreement between theory and experiment for the high-energy $A_{1g}$ phonon mode is improved when these effects are taken into account. Finally, we examine the nature of the superconducting state recently observed in SnSe$_2$ under nonhydrostatic pressure and predict the emergence of superconductivity with a comparable critical temperature in SnS$_2$ under similar experimental conditions. Interestingly, in the periodic lattice distorted phases, the critical temperature is found to be reduced by an order of magnitude due to the restructuring of the Fermi surface.

description: As-received and cleaned soda-lime glass surfaces corroded in high relative humidity of 95 % at a temperature of 60 °C for times up to one week are investigated by means of TOF-SIMS, SNMS, XPS, NRA, ERD, RBS, GIXR, AFM, SEM and optical microscopy. Distinct differences in the corrosion behavior are observed for as-received and cleaned glass surfaces. Changes in element concentration in the glass interface and in the topography of the glass surfaces are described for different exposure times in humidity. They are combined with variations in density of the modified surface layer. Cleaning before the corrosion treatment drastically reduces degradation; cleaning after the corrosion treatment can restore the surface.

description: The reaction pp->p K0 pi+ Lambda has been studied with the ANKE spectrometer at COSY-Juelich at a beam momentum of 3.65 GeV/c in order to search for a possible signal of the pentaquark Theta+(1540), decaying into the p K0 system. By detecting four charged particles in the final state, the K0 and the Lambda have been reconstructed to tag strangeness production. It has been found that the pi+ Lambda missing-mass spectrum displays no significant signal expected from the Theta+(1540) excitation. The total cross section for the reaction pp->p K0 pi+ Lambda has been deduced, as well as an upper limit for the Theta+ production cross section. The intermediate Delta++ K0 Lambda state is found to provide a significant contribution to the reaction.

description: This paper investigates the problem of designing data-driven stochastic Model Predictive Control (MPC) for linear time-invariant systems under additive stochastic disturbance, whose probability distribution is unknown but can be partially inferred from data. We propose a novel online learning based risk-averse stochastic MPC framework in which Conditional Value-at-Risk (CVaR) constraints on system states are required to hold for a family of distributions called an ambiguity set. The ambiguity set is constructed from disturbance data by leveraging a Dirichlet process mixture model that is self-adaptive to the underlying data structure and complexity. Specifically, the structural property of multimodality is exploit-ed, so that the first- and second-order moment information of each mixture component is incorporated into the ambiguity set. A novel constraint tightening strategy is then developed based on an equivalent reformulation of distributionally ro-bust CVaR constraints over the proposed ambiguity set. As more data are gathered during the runtime of the controller, the ambiguity set is updated online using real-time disturbance data, which enables the risk-averse stochastic MPC to cope with time-varying disturbance distributions. The online variational inference algorithm employed does not require all collected data be learned from scratch, and therefore the proposed MPC is endowed with the guaranteed computational complexity of online learning. The guarantees on recursive feasibility and closed-loop stability of the proposed MPC are established via a safe update scheme. Numerical examples are used to illustrate the effectiveness and advantages of the proposed MPC.

description: We propose CP asymmetries based on triple product correlations in the decays sbottom_m -> top chargino_j with subsequent decays of top and chargino_j. For the subsequent chargino_j decay into a leptonic final state l^- νneutralino_1 we consider the three possible decay chains chargino_j -> l^- sneutrino -> l^- νneutralino_1, chargino_j -> slepton_n ν-> l^- νneutralino_1 and chargino_j -> W^- neutralino_1 -> l^- νneutralino_1. We consider two classes of CP asymmetries. In the first class it must be possible to distinguish between different leptonic chargino_j decay chains, whereas in the second class this is not necessary. We consider also the 2-body decay chargino_j -> W^- neutralino_1, and we assume that the momentum of the W boson can be measured. Our framework is the minimal supersymmetric standard model with complex parameters. The proposed CP asymmetries are non-vanishing due to non-zero phases for the parameters μand/or A_b. We present numerical results and estimate the observability of these CP asymmetries.

Mechanisms of the formation of gas bubbles in heat treatment of glass-silicate tiles

Publisher: name: Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft
Year: 2022
Subjects: subject: 660

description: Theoretical research has been done into the mechanisms of the formation of gas bubbles which takes place during the sintering of the glass granulation product under the conditions of heating its upper layer. It is shown that in the bubble, there is a possibility of an inverse thermal distribution which will lead to a thermal jump on its boundary. At the thermal processing temperatures, the presence of CO2 increases the effect of absorption of the radiation conditioned by the spectral zones. Experimentally, it has been proved that a thermal field inversion takes place in the presence of an inner diffusing layer joined to a clearly transparent one for the thermal radiation of the material.
Family constellation and cognitive development in three-and five-year-old children from the Millennium Cohort Study
Creators: name: Hanna, Dana Joyce
Publisher: name: The Australian National University
Year: 2015

description: Using data from the British Millennium Cohort Study, this dissertation studies the effect of the family constellation on the cognitive development levels of children at the ages of three and five years. The first paper looks at the correlation between family size, birth order and the age gap between sibling births and cognitive ability test results at the ages of three and five years. For three-year-olds, family size and birth order are negatively correlated with vocabulary scores and school readiness scores. Larger age gaps between subsequent children have the potential to mitigate this impact. At the age of five years, family size is still negatively correlated with vocabulary and spatial reasoning test scores. While birth order is negatively correlated with vocabulary scores, it is positively correlated with spatial reasoning scores. Spacing between siblings still has an ameliorating effect for the younger sibling, yet is somewhat weaker than at the age of three. Interestingly, family constellation aspects have no statistical relationship to non-verbal reasoning (picture similarity) scores at age five. Paper two investigates the relationship between the family constellation and the progress of children's vocabulary ability between the ages of three and five years. The results give limited evidence that family size has a statistical, or sizeable, relationship with the progress of children's cognitive ability. Rather, children of higher birth order and those raised by single parents show, on average, smaller rates of progress between the ages of three and five. Single parenting has the greatest (negative) effect on those children with higher levels of initial ability. The third paper uses an instrumental variable approach to account for problems resulting from endogenously determined family size. Twins at last birth is used to instrument for family size. Results indicate that while there is a negative relationship between family size and children's cognitive outcomes, the relationship is weak. Rather, there is stronger evidence for birth order driving the differences in cognitive scores. Evidence pertaining to the effect of the spacing between a child and its older sibling suggests that greater spacing may be beneficial for the younger sibling.
The 'grinding marks' of ancient glass - a critical assessment

Subjects: subject: 660

description: The theoretical reconstruction of ancient manufacturing methods depends on a correct interpretation of the extant manufacturing traces. An error with serious consequences was the misinterpretation of the typical scratches of ancient glass as grinding marks. Generations of archaeologists were convinced that especially the Roman glassworkers had a superior command of the art of glass cutting and grinding, which supposedly was never again surpassed in history. A few years ago, a new interpretation of the typical scratches of ancient glass was given, explaining the scratches as traces of the hot manufacturing process. Recent scientific investigations support this new perception. A summarizing presentation of the topic is given here to provide a realistic starting point for further research about the ancient glass manufacturing methods.

It contains a user-friendly graphical front end, a simplified version of a furnace operation station, that allows modifying furnace settings (batch charging rate and properties, setup of bubblers, coolers, fuel profile, etc.). Behind this user interface, coupled glass and combustion models are run. The output of these calculations (shown again as a set of operator-friendly control screens) displays temperatures in positions where thermocouples and pyrometers are located in reality, exhaust gas properties, glass flow patterns, location of spring zone, quality indices, etc. The simulator has been validated and shows good agreement with reality.

description: We report the discovery of 40 new globular clusters (GCs) that have been found in surveys of the halo of M31 based on INT/WFC and CHFT/Megacam imagery. A subset of these these new GCs are of an extended, diffuse nature, and include those already found in Huxor et al. (2005). The search strategy is described and basic positional and V and I photometric data are presented for each cluster. For a subset of these clusters, K-band photometry is also given. The new clusters continue to be found to the limit of the survey area (~100 kpc), revealing that the GC system of M31 is much more extended than previously realised. The new clusters increase the total number of confirmed GCs in M31 by approximately 10% and the number of confirmed GCs beyond 1 degree (~14 kpc) by more than 75%. We have also used the survey imagery as well recent HST archival data to update the Revised Bologna Catalogue (RBC) of M31 globular clusters.

Αποτελούν σημαντικό παράγοντα στην προσπάθεια να γίνουν τα σχολεία πιο ¨ανοιχτά¨ σε όλους ανεξαιρέτως τους μαθητές αλλά και γενικά στην κοινωνία. Επίσης σημαντικοί παράγοντες στο σχηματισμό των αντιλήψεων των ειδικών παιδαγωγών είναι: η συνεργασία με τον δάσκαλο της γενικής αγωγής, η κατάρτιση που έχουν λάβει, η μορφή της αναπηρίας των μαθητών, ο φόρτος εργασίας κατά τη διαδικασία της συνεκπαίδευσης και η εμπειρία που έχουν στην ειδική αγωγή.
description: In inclusive education settings, schools change and consequently educators' role change. Success of inclusive education depends on teacher's perceptions of both general and special education and how they perceive children's differences in the classroom. Special educators comprise, a very important factor for schools to be open to every child and for society generally. Collaboration among special and general educators, proficiency in inclusive education, types of children's disabilities, extra workload in inclusive education circumstances and what experience they have regarding special education, are important factors too.
Type Ia Supernovae from wide white-dwarfs triples

description: For ultra-wide systems (with outer orbit >$10^{3}{\rm AU})$ the galactic field is collisional. Hence, ultra-wide triple white-dwarfs (TWDs) can be perturbed, by flyby stars, to sufficiently high outer eccentricity such that the triple becomes dynamically unstable. An unstable triple undergoes multiple binary-single resonant encounters between all three WDs. These encounters might result in a direct collision between any random two WDs and lead to a Type Ia supernova (SN) event. In case where the multiple resonant encounters did not produce a collision a compact binary is formed (while the third WD is ejected), this binary either collides or merges via gravitational wave emission, similar to the classic double-degenerate (DD) channel. In this research study we estimate the galactic rates of Type Ia SN from the direct collision channel is to be $0.1\%-4\%$ and primarily $2\%-36\%$ from the DD scenario.

description: This report summarises progress made in estimating the local density of dark matter ($ρ_{\mathrm{DM,\odot}}$), a quantity that is especially important for dark matter direct detection experiments. We outline and compare the most common methods to estimate $ρ_{\mathrm{DM,\odot}}$ and the results from recent studies, including those that have benefited from the observations of the ESA/Gaia satellite. The result of most local analyses coincide within a range of $ρ_{\mathrm{DM,\odot}} \simeq \text{0.4--0.6}\,\mathrm{GeV/cm^3} = \text{0.011--0.016}\,\mathrm{M_\odot / pc^3}$, while a slightly lower range of $ρ_{\mathrm{DM,\odot}} \simeq \text{0.3--0.5}\,\mathrm{GeV/cm^3} = \text{0.008--0.013}\,\mathrm{M_\odot / pc^3}$ is preferred by most global studies. In light of recent discoveries, we discuss the importance of going beyond the approximations of what we define as the Ideal Galaxy (a steady-state Galaxy with axisymmetric shape and a mirror symmetry across the mid-plane) in order to improve the precision of $ρ_{\mathrm{DM,\odot}}$ measurements. In particular, we review the growing evidence for local disequilibrium and broken symmetries in the present configuration of the Milky Way, as well as uncertainties associated with the Galactic distribution of baryons. Finally, we comment on new ideas that have been proposed to further constrain the value of $ρ_{\mathrm{DM,\odot}}$, most of which would benefit from Gaia's final data release.

Realizing a Sustainable Future: How Rapid Advancements in Technology are Enabling Global Implementation of Sustainable Practices to Make Economic Sense

description: The many effects of climate change, including the rising earth's temperature, the increased frequency of natural disasters, the melting sea ice, the reduction of ice mass have caused adverse impacts to the way we live our lives. Many climate agreements, an essential part of putting the issue of climate change at the forefront of policy makers’ thinking, have been organized, from the Kyoto Protocol, the Copenhagen Summit, and the Paris Agreement. Unfortunately, not all of these conferences ended up with a great success. For instance, the Kyoto Protocol and the Copenhagen Summit failed because of fundamental disagreements on whether developed and developing countries should share the same responsibility, as unaffordable prices on renewable energy had prevented developing countries to fuel their neck-breaking development pace without building cheap, but highly polluting power plants, mostly fuelled by readily available coal. A key part of the Paris Agreement’s success is its emphasis on individual targets by each country to lower their greenhouse gas emissions, uniquely tailored to each country needs and limitations. Advancements in technology have brought the era of exorbitant price on renewable energy to a close. Rapidly falling solar panels and wind turbines cost has allowed every country to integrate sustainable electricity into their energy plan at comparable costs to coal and gas-powered power plants. The rapidly falling price of ever-increasingly powerful battery invalidates the argument that environmentally friendly energy equals to high cost. Advancement in battery densities and costs are making expensive electric cars a thing of the past. Therefore, environmentally conscious actions and saving cost can be done simultaneously. Lastly, this paper will also detail various steps needed to be made by policy makers to significantly lower their carbon emissions.

description: Nowadays, a huge amount of knowledge has been amassed in digital agriculture. This knowledge and know-how information are collected from various sources, hence the question is how to organise this knowledge so that it can be efficiently exploited. Although this knowledge about agriculture practices can be represented using ontology, rule-based expert systems, or knowledge model built from data mining processes, the scalability still remains an open issue. In this study, we propose a knowledge representation model, called an ontology-based knowledge map, which can collect knowledge from different sources, store it, and exploit either directly by stakeholders or as an input to the knowledge discovery process (Data Mining). The proposed model consists of two stages, 1) build an ontology as a knowledge base for a specific domain and data mining concepts, and 2) build the ontology-based knowledge map model for representing and storing the knowledge mined on the crop datasets. A framework of the proposed model has been implemented in agriculture domain. It is an efficient and scalable model, and it can be used as knowledge repository a digital agriculture.

description: Τις τελευταίες δεκαετίες έχουν αναπτυχθεί και συνεχώς δοκιμάζονται πλήθος θεραπευτικών παρεμβάσεων αναφορικά με την καταπολέμηση της ουσιοεξάρτησης. Στην διάρκεια των περασμένων δεκαετιών η εκάστοτε τρέχουσα επιστημονική γνώση σχετικά με το θέμα διήλθε από πολλές τροποποιήσεις, οι οποίες δεν υπήρξαν πάντα αλάνθαστες. Η σημερινή επιστημονική άποψη για την αντιμετώπιση του προβλήματος αποτελεί ένα από τα σημαντικότερα όπλα για την αντιμετώπιση του. Η εκπαίδευση των επαγγελματιών υγείας των εργαζομένων στο χώρο της ουσιοεξάρτησης φαίνεται ότι αποτελεί έναν από τους παράγοντες που σχετίζονται θετικά με την έκβαση του θεραπευτικού αποτελέσματος.Στο πόνημα αυτό θα γίνει μια προσπάθεια αξιολόγησης του προγράμματος απεξάρτησης της θεραπευτικής κοινότητας ΑΡΓΩ .

description: Der Prosaiker, Dramatiker und Hörspielautor Jan Decker reflektiert in diesem Essay über Bedingungen und Widerstände des literarischen Schreibens. Dabei geht es weniger um poetologische Verfahren als vielmehr um ein Hinterfragen der Bedingungen und Dispositionen, die einen Menschen dazu verleiten, einen literarischen Text dort entstehen zu lassen, wo sich ein Selbstempfinden und die Welt berühren. Ein Bogen wird gespannt, der über die Erotik und Körperlichkeit des Schreibakts hinweg letztlich dazu führt, die »Ursprungsneurose« als das zu pflegende Enigma des Autors zu erkennen.

description: Conventional algorithmic fairness is West-centric, as seen in its sub-groups, values, and methods. In this paper, we de-center algorithmic fairness and analyse AI power in India. Based on 36 qualitative interviews and a discourse analysis of algorithmic deployments in India, we find that several assumptions of algorithmic fairness are challenged. We find that in India, data is not always reliable due to socio-economic factors, ML makers appear to follow double standards, and AI evokes unquestioning aspiration. We contend that localising model fairness alone can be window dressing in India, where the distance between models and oppressed communities is large. Instead, we re-imagine algorithmic fairness in India and provide a roadmap to re-contextualise data and models, empower oppressed communities, and enable Fair-ML ecosystems.

description: A sensor with β"-Al2O3 as solid electrolyte was used in the tin melt for the determination of sodium activity. The chemical, microstructural and functional properties of the home-made β"-alumina were determined. The properties of the home-made ceramics do not much differ from those of commercially obtained materials, which have been used for the purpose of comparison. The behaviour of probes with the reference electrodes sodium, tin-sodium alloys and sodium borosilicate glass was investigated within the scope of emf measurements. No longtime-stable measurements could be carried out with the use of the sensors with sodium as well as tin-sodium reference electrodes. The observed drift of the emf signal is explained by a partial electronic conductivity of the solid electrolyte. Nernst behaviour was found while using a probe with sodium reference electrolyte, i.e. the emf shows a linear dependence on the logarithm of the sodium content in the melt. A proportionally stable behaviour of the emf signal was indicated by measurements with a sodium glass reference system. With the alteration of the sodium concentration the probe reacted spontaneously and reversibly. Besides, an exact Nernst behaviour is indicated. Applying several probes of the same type a displacement of Nernst straight lines is observed, which diverge up to about 400 mV. The family of the Nernst straight lines at multiple use of a single probe moves within a relatively narrow range of only about 25 mV. This permits comparatively precise measurements (error is dependent on the position in the concentration decade). Each probe of the type developed here has to be tested and calibrated by repeated application. A probe delivery with individual characteristic is proposed. The determination of the sodium contents in melts of the basic material and of tin from the float glass process yielded in both cases about 2 wt ppm. These values show that the sodium contents of the tin melt do not differ before and after use.

description: A broadband squeezed vacuum photon field is characterized by a complex squeezing function. We show that by controlling the wavelength dependence of its phase it is possible to change the dynamics of the atomic polarization interacting with the squeezed vacuum. Such a phase modulation effectively produces a finite range temporal interaction kernel between the two quadratures of the atomic polarization yielding the change in the decay rates as well as the appearance of additional oscillation frequencies. We show that decay rates slower than the spontaneous decay rate can be achieved even for a squeezed bath in the classic regime. For linear and quadratic phase modulations the power spectrum of the scattered light exhibits narrowing of the central peak due to the modified decay rates. For strong phase modulations side lobes appear symmetrically around the central peak reflecting additional oscillation frequencies.
