description: Η ποίηση της Μακρονήσου κατέχει εξέχουσα θέση στη νεοελληνική ποίηση της εξορίας. Στη μελέτη μας επιχειρούμε μια οριζόντια ανάγνωση της ποίησης της Μακρονήσου, βασιζόμενη σε ορισμένες κατηγορίες μοτίβων, οι οποίες προέκυψαν από τη συγκριτική εξέταση του corpus των ποιημάτων. Τα ποιήματα εντάσσονται στο ιστορικό πλαίσιο της εμφυλιακής και μετεμφυλιακής Ελλάδας, ενώ παράλληλα διερευνάται αυτή καθαυτή η λογοτεχνική αρχιτεκτονική τους. Οι πολιτικές στοχεύσεις των ποιητών προβάλλονται επί των αισθητικών αναζητήσεών τους και αντιστρόφως. Τα μοτίβα συνυφαίνουν μια γενική εικόνα μιας έντονα βιωματικής ποίησης, στην οποία κυριαρχεί το τραύμα. Το τοπίο και τα φυσικά φαινόμενα μετατρέπονται σε εργαλεία βασανιστηρίων, η χρονική διάρκεια συρρικνώνεται στο εικοσιτετράωρο της καθημερινότητας του εγκλεισμού. Οι διάφορες μορφές βασανιστηρίων καταγράφονται λεπτομερειακά, ο θάνατος παραμονεύει σε κάθε ποίημα. Βιαστικά πορτρέτα αποτυπώνουν την ανθρωπογεωγραφία της εξορίας, ενώ ο καμβάς των συναισθημάτων βάφεται μαύρος. Η ποίηση εν τέλει κατορθώνει να αναδείξει όψεις του συλλογικού υποκειμένου των εξορίστων και της πραγματικότητας της εξορίας ανατέμνοντας τον μηχανισμό της εξουσίας. Ένα άλλο συλλογικό υποκείμενο προβάλλει μέσα από τις στάχτες της Μακρονήσου, η κοινότητα των ποιητών της.
description: The poetry of Makronisos holds a prominent place in Modern Greek Poetry of exile. In our research we attempt a horizontal reading of the poetry of Makronisos based on some motifs, which were developed from the comparative studying of corpus's poems. The poems are included in the historical framework of Civil and post-Civil War Greece while their literary structure is explored. Poets' political targets are projected on their quest on aesthetics and vice versa. The motifs dovetail an overall picture of a poetry strongly based on experience, where the idea of trauma is dominant. The landscape along with the natural phenomena are converted to tools of torture, time duration is shriveled to a twenty – four hour daily life of imprisonment. The various forms of torture are recorded in detail. Death lurks in every poem. Passing images capture the anthropogeography of exile while the canvas of emotions is painted black. In the end, poetry manages to feature aspects of exiles' collective subject as well as the reality of exile thus, deconstructing the mechanisms of power. Another collective subject emerges from the ashes of Makronisos: The community of its poets.

description: We present the results of a systematic search for gravitationally-lensed continuum Lyman break `drop-outs' beyond a redshift 7 conducted via very deep imaging through six foreground clusters undertaken with the Hubble and Spitzer Space Telescopes. The survey has yielded 10 z-band and 2 J-band drop-out candidates to photometric limits of J_110~=26.2 AB (5sigma). Taking into account the magnifications afforded by our clusters (1-4 magnitudes), we probe the presence of z>7 sources to unlensed limits of J_{110}~=30 AB, fainter than those charted in the Hubble Ultradeep Field. To verify the fidelity of our candidates we conduct a number of tests for instrumental effects which would lead to spurious detections, and carefully evaluate the likelihood of foreground contamination by considering photometric uncertainties in the drop-out signature, the upper limits from stacked IRAC data and the statistics of multiply-imaged sources. Overall, we conclude that we can expect about half of our sample of z-band drop-outs are likely to be at high redshift. An ambitious infrared spectroscopic campaign undertaken with the NIRSPEC spectrograph at the WM Keck Observatory for seven of the most promising candidates failed to detect any Lyman-alpha emission highlighting the challenge of making further progress in this field. While the volume density of high redshift sources will likely remain uncertain until more powerful facilities are available, our data provides the first potentially interesting constraints on the UV luminosity function at z~=7.5 at intrinsically faint limits. We discuss the implications of our results in the context of the hypothesis that the bulk of the reionizing photons in the era 7

description: In this paper, we explore the period tripling and period quintupling renormalizations below $C^2$ class of unimodal maps. We show that for a given proper scaling data there exists a renormalization fixed point on the space of piece-wise affine maps which are infinitely renormalizable. Furthermore, we show that this renormalization fixed point is extended to a $C^{1+Lip}$ unimodal map, considering the period tripling and period quintupling combinatorics. Moreover, we show that there exists a continuum of fixed points of renormalizations by considering a small variation on the scaling data. Finally, this leads to the fact that the tripling and quintupling renormalizations acting on the space of $C^{1+Lip}$ unimodal maps have unbounded topological entropy.

description: Diffusive shock acceleration is a prominent mechanism for producing energetic particles in space and in astrophysical systems. Such energetic particles have long been predicted to affect the hydrodynamic structure of the shock, in turn leading to CR spectra flatter than the test-particle prediction. However, in this work along with a companion paper, C. C. Haggerty and D. Caprioli, 2020, arXiv:2008.12308 [astro-ph.HE], we use self-consistent hybrid (kinetic ions-fluid electrons) simulations to show for the first time how CR-modified shocks actually produce steeper spectra. The steepening is driven by the enhanced advection of CRs embedded in magnetic turbulence downstream of the shock, in what we call the "postcursor". These results are consistent with multi-wavelength observations of supernovae and supernova remnants and have significant phenomenological implications for space/astrophysical shocks in general.

description: The aim of the present thesis was recording and analysis of all the serious rail accidents around the world since 1950. The thesis examines the literature on rail safety and the various aspects of rail safety (accident causes and impacts) and the definitions of all rail safety incidents. A definition of serious rail accidents is developed and based on this a field research for data on all the rail accidents around the world since 1950 is performed. The most serious accidents based on their causes and impacts direct (number of casualties) and indirect (changes to rail safety regulations/legislation on the global, continental and/or national level) are presented. Furthermore, an analysis on all the serious rail accidents recorded from 1950 until today is performed to examine the safety of passenger railway and the evolution of safety over the years. The analysis records number of accidents and casualties per continent and country, per decade and also per cause of the accident where this is identified. The results are used to show the position of the railway in relation to the other means of transport (road, waterborne, air) in relation to safety and to show trends and their development over the years. Finally, the conclusions of the analysis are presented along with potential fields for future research.

description: Equilibrium polyethylene crystal structure, cohesive energy, and elastic constants are calculated by density-functional theory applied with a recently proposed density functional (vdW-DF) for general geometries [Phys. Rev. Lett. 92, 246401 (2004)] and with a pseudopotential-planewave scheme. The vdW-DF with its account for the long-ranged van der Waals interactions gives not only a stabilized crystal structure but also values of the calculated lattice parameters and elastic constants in quite good agreement with experimental data, giving promise for successful application to a wider range of polymers.

description: We consider estimation of a multivariate normal mean vector under sum of squared error loss. We propose a new class of smooth estimators parameterized by αdominating the James-Stein estimator. The estimator for α=1 corresponds to the generalized Bayes estimator with respect to the harmonic prior. When αgoes to infinity, the estimator converges to the James-Stein positive-part estimator. Thus the class of our estimators is a bridge between the admissible estimator (α=1) and the inadmissible estimator (α=\infty). Although the estimators have quasi-admissibility which is a weaker optimality than admissibility, the problem of determining whether or not the estimator for α>1 admissible is still open.
Limit to mass sensitivity of nanoresonators with random rough surfaces due to intrinsic sources and interactions with the surrounding gas

description: We investigate initially the influence of thermomechanical and momentum exchange noise on the limit to mass sensitivity of nanoresonators with random rough surfaces, which are characterized by the roughness amplitude, the correlation length, and the roughness exponent H. In fact, the limit to mass sensitivity increases with increasing roughness (decreasing H and/or increasing ratio roughness amplitude/correlation length) if the quality factor associated with thermomechanical noise is larger than that due to momentum exchange noise. Finally, the influence of adsorption-desorption noise, which is also influenced by the surface morphology, is shown to play minimal role in presence of the other two noise sources.

description: Fractionalization is a phenomenon where an elementary excitation partitions into several pieces. This picture explains non-trivial transport through a junction of one-dimensional edge channels defined by topologically distinct quantum Hall states, for example, a hole-conjugate state at Landau-level filling factor $ν$ = 2/3. Here we employ a time-resolved scheme to identify an elementary fractionalization process; injection of charge q from a non-interaction region into an interacting and scattering region of one-dimensional channels results in the formation of a collective excitation with charge $(1-\textit{r})\textit{q}$ by reflecting fractionalized charge $\textit{rq}$. The fractionalization factors, $\textit{r}$ = 0.34$\pm$0.03 for $ν$ = 2/3 and $\textit{r}$ = 0.49$\pm$0.03 for $ν$ = 2, are consistent with the quantized values of 1/3 and 1/2, respectively, which are expected in the disorder dominated regime. The scheme can be used for generating and transporting fractionalized charges with a well-defined time course along a well-defined path.

Predicting sound propagation in fitted workrooms
Creators: name: Li, Ke
Publisher: name: University of British Columbia
Year: 2009

description: When predicting sound propagation in rooms such as industrial workrooms, a major factor that must be taken into consideration is the presence of 'fittings' — obstacles such as machines and stockpiles — in the room. Besides the fitting spatial distribution, there are two important parameters used in prediction models to describe the fittings — one is the fitting density — a measure of the number of fittings and the average fitting crosssection area — and the other is the fitting absorption coefficient. While ranges of typical fitting densities are known, no method exists for measuring or estimating the fitting density in a given factory. Furthermore, theoretical expressions for calculating fitting density assume small fittings and high frequency. The aim of this research project is to develop and test a method for determining the fitting density in industrial workrooms. To achieve this objective a correction formula was derived for calculating the fitting density in the case of large fitting dimensions. The variation of fitting density with frequency was found from sound propagation measurements in large fitted regions; a formula to express the relationship is determined by statistical methods and this model was validated experimentally in a scale-model workroom and in a machine shop with the help of prediction models. A correction formula for calculating fitting absorption coefficient using empty and fitted room absorption coefficients was derived and validated using measurement in a machine shop. A n image-source model — based on improving an existing model used for infinite regions — was developed to predict sound propagation in fitted rooms and validated in several workrooms. This model provided a fast, workable and accurate alternative to existing fitted-room models.

We examined problems related to Slang and elements specific to the Turkish Slang and specifically the Greek elements in Turkish Slang. Furthermore, we examined the problem of etymology of Argot. We studied the sociolinguistic dimension of Argot with emphasis on the relationship with language of young people. We presented information about the position of Slang in literature, especially in the Turkish literature. Then we worked on the Greek dialectical elements in Turkish Slang, Greek origin words which are present in a common Turkish and appear with different meanings in Turkish Slang, foreign elements in Turkish Slang and we referred to the semantic evolution of Greek loans of Turkish Slang. We finished the thesis with a list of Greek elements in Turkish Slang.

description: We argue that the critical dynamical fluctuations predicted by the mode-coupling theory (MCT) of glasses provide a natural mechanism to explain the breakdown of the Stokes-Einstein relation. This breakdown, observed numerically and experimentally in a region where MCT should hold, is one of the major difficulty of the theory, for which we propose a natural resolution based on the recent interpretation of the MCT transition as a bona fide critical point with a diverging length scale. We also show that the upper critical dimension of MCT is d_c=8.

An Ownership Policy and Deadlock Detector for Promises

Subjects: subject: Programming Languages (cs.PL)

description: Task-parallel programs often enjoy deadlock freedom under certain restrictions, such as the use of structured join operations, as in Cilk and X10, or the use of asynchronous task futures together with deadlock-avoiding policies such as Known Joins or Transitive Joins. However, the promise, a popular synchronization primitive for parallel tasks, does not enjoy deadlock-freedom guarantees. Promises can exhibit deadlock-like bugs; however, the concept of a deadlock is not currently well-defined for promises. To address these challenges, we propose an ownership semantics in which each promise is associated to the task which currently intends to fulfill it. Ownership immediately enables the identification of bugs in which a task fails to fulfill a promise for which it is responsible. Ownership further enables the discussion of deadlock cycles among tasks and promises and allows us to introduce a robust definition of deadlock-like bugs for promises. Cycle detection in this context is non-trivial because it is concurrent with changes in promise ownership. We provide a lock-free algorithm for precise runtime deadlock detection. We show how to obtain the memory consistency criteria required for the correctness of our algorithm under TSO and the Java and C++ memory models. An evaluation compares the execution time and memory usage overheads of our detection algorithm on benchmark programs relative to an unverified baseline. Our detector exhibits a 12% (1.12$\times$) geometric mean time overhead and a 6% (1.06$\times$) geometric mean memory overhead, which are smaller overheads than in past approaches to deadlock cycle detection.

description: We develop a new approach to formulate and prove the weak uncertainty inequality which was recently introduced by Okoudjou and Strichartz. We assume either an appropriate measure growth condition with respect to the effective resistance metric, or, in the absence of such a metric, we assume the Poincare inequality and reverse volume doubling property. We also consider the weak uncertainty inequality in the context of Nash-type inequalities. Our results can be applied to a wide variety of metric measure spaces, including graphs, fractals and manifolds.

Μέσα από αυτή την διαδικασία, διαπιστώσαμε ότι το Αγιοσαββιτικό Τυπικό, αν και θεωρείται η πηγή του μοναστηριακού Τυπικού, άλλοτε αντιγράφεται από την νεώτερη προς αυτό μοναστηριακή πράξη, ενώ άλλες φορές αγνοείται. Ωστόσο, αυτό δεικνύει την ελευθερία των Τυπικών μας και των μοναστικών κέντρων.

description: The aim of the present thesis was to compare the typological provisions of the Ritual of four Mt Athos monasteries (those of Dionysios, Philotheos, St. Paul and Konstamonitis) and, ultimately, their relationship with the corresponding provisions of the Jerusalem Ritual of St Savvas Monastery. Through this process, we have ascertained that St Savvas Ritual, though considered to have been the source of the monasterial Ritual, is, at times, copied from the latest monasterial act, while it is ignored at others. However, this fact shows the freedom of our Rituals and monastic centres. We have examined the various Ritual Provisions which have been recorded on the holy mountain and the conditions that have influenced this record, the emphasis being on the 19th century. After presenting the Rituals to be examined, we have dealt with their structure and general provisions. Next, we talked about issues concerning the almanac, but also the periods of Triodion and Pentecost. Provisions addressed to monks, which regulate daily life within the monastic fraternity, are also rather interesting. In addition, we quote the citations of several provisions in order to, indicatively, see the agreement and divergence points of our Rituals.

description: The structure-thermodynamic stability relationship in vitreous silica is investigated using machine learning and a library of 24,157 inherent structures generated from melt-quenching and replica exchange molecular dynamics simulations. We find the thermodynamic stability, i.e., enthalpy of the inherent structure ($e_{\mathrm{IS}}$), can be accurately predicted by both linear and nonlinear machine learning models from numeric structural descriptors commonly used to characterize disordered structures. We find short-range features become less indicative of thermodynamic stability below the fragile-to-strong transition. On the other hand, medium-range features, especially those between 2.8-~6 $\unicode{x212B}$;, show consistent correlations with $e_{\mathrm{IS}}$ across the liquid and glass regions, and are found to be the most critical to stability prediction among features from different length scales. Based on the machine learning models, a set of five structural features that are the most predictive of the silica glass stability is identified.

description: The aim of the present thesis was the annotated translation of a German text into the Greek language. The chosen text was extracted from the book Literarische Übersetzung. Geschichte – Theorie – Kulturelle Wirkung by Jörn Albrecht, particularly chapter 7.2, in which some aspects of the Skopos theory is discussed in regard to literary translation. Following the presentation of extratextual and intratextual features, a translation of the passage was attempted as well as the extraction of terms detected in the text. Consequently, a glossary of the extracted terms was created based on translatological and/or linguistic criteria. Furthermore, the validation of the terms was analyzed, relying on translatological works, bilingual and monolingual dictionaries, plus official websites. The present thesis was completed after annotating the difficulties encountered during the translation on the one hand, and the choices made by the translator concerning lexical, grammatical or syntactical elements, style, as well as pragmatic factors on the other hand.

description: The Wigner Transform (WT) has been extensively used in the formulation of phase-space models for a variety of wave propagation problems including high-frequency limits, nonlinear and random waves. It is well known that the WT features counterintuitive 'interference terms', which often make computation impractical. In this connection, we propose the use of the smoothed Wigner Transform (SWT), and derive new, exact equations for it, covering a broad class of wave propagation problems. Equations for spectrograms are included as a special case. The 'taming' of the interference terms by the SWT is illustrated, and an asymptotic model for the Schroedinger equation is constructed and numerically verified.

Vibrations and stability of constrained rotating strings and disks at supercritical speeds
Creators: name: Yang, Longxiang
Publisher: name: University of British Columbia

description: This thesis presents an analysis of the vibration and stability characteristics of rotating strings and disks at supercritical speeds. The dynamic interactions between an idealized rotating circular string and a stationary constraint consisting of a spring, a damper, a mass or a frictional restraint are studied. The method of traveling waves is applied to develop the characteristic equation. The physics of the interactions between the string and the restraints are discussed in depth. The nonlinear vibrations of an elastically-constrained rotating string are investigated. The nonlinearities of the string deformation and the spring stiffness are considered. Butenin’s method is adopted to develop a closed-form analytical solution for single-mode oscillations of the system. The analysis shows that the geometric nonlinearity restrains the flutter instability of the string at supercritical speeds. The effects of rigid-body motions on free oscillations of an elastically-constrained rotating disk are studied. The coupling between the translational rigid-body motion and the flexible body deformation is shown to reduce the divergence instability of the disk, but the tilting rigidbody motion does not change the stability characteristics. An analysis of nonlinear vibrations of an elastically-constrained rotating flexible disk is developed. The equations of motion are presented by using von Karman thin plate theory. The stress function is analytically solved by assuming a multi-mode transverse displacement field. The study shows that the geometric nonlinearity generates hardening effects on the dynamics of a rotating disk, and the unbounded motions at divergence and flutter speeds predicted by the existing linear analyses do not take place because of the large-amplitude vibrations.

description: The first-order differential equation of exponential relaxation can be generalized by using either the fractional derivative in the Riemann-Liouville (R-L) sense and in the Caputo (C) sense, both of a single order less than 1. The two forms turn out to be equivalent. When, however we use fractional derivatives of distributed order (between zero and 1), the equivalence is lost, in particular on the asymptotic behaviour of the fundamental solution at small and large times. We give an outline of the theory providing the general form of the solution in terms of an integral of Laplace type over a positive measure depending on the order-distribution. We consider with some detail two cases of fractional relaxation of distributed order: the double-order and the uniformly distributed order discussing the differences between the R-L and C approaches. For all the cases considered we exhibit plots of the solutions for moderate and large times.

description: We stress that the lack of direct evidence for supersymmetry forces the soft mass parameters to lie very close to the critical line separating the broken and unbroken phases of the electroweak gauge symmetry. We argue that the level of criticality, or fine-tuning, that is needed to escape the present collider bounds can be quantitatively accounted for by assuming that the overall scale of the soft terms is an environmental quantity. Under fairly general assumptions, vacuum-selection considerations force a little hierarchy in the ratio between m_Z^2 and the supersymmetric particle square masses, with a most probable value equal to a one-loop factor.

title: Media, Military, Militarism: Media Consumption, Awareness of U.S. Military Foreign Policy, and Support for War

description: This study examines the relationship between the media, attitudes towards supporting war, and military awareness. Online survey data were collected from a four-year university located in a heavily militarized area. This study found that having knowledge of Afghanistan and Iraq War facts negatively affected one's decision to support war and was the strongest predictor of this decision. The media was not found to be a significant predictor impacting this knowledge when controlling for other variables. Political ideology and other related variables were found to be more influential of this knowledge. These findings imply that the public may be imprudently supporting war without proper exposure to the facts or without regard to reality.

description: Constrained low-rank matrix approximations have been known for decades as powerful linear dimensionality reduction techniques to be able to extract the information contained in large data sets in a relevant way. However, such low-rank approaches are unable to mine complex, interleaved features that underlie hierarchical semantics. Recently, deep matrix factorization (deep MF) was introduced to deal with the extraction of several layers of features and has been shown to reach outstanding performances on unsupervised tasks. Deep MF was motivated by the success of deep learning, as it is conceptually close to some neural networks paradigms. In this paper, we present the main models, algorithms, and applications of deep MF through a comprehensive literature review. We also discuss theoretical questions and perspectives of research.

description: We establish that the ability of a localized trapping potential to bind weakly-interacting bosons is dramatically enhanced in the vicinity of the threshold of formation of the single-particle bound-state of the trap. Specifically, for repulsive particles and a super-threshold trapping potential the equilibrium number of bound bosons and the size of the ground state diverge upon approaching the single-particle threshold from above. For attractive interactions and a sub-threshold trap a collective bound state always forms for a sufficiently large number of bosons despite the inability of interparticle attraction alone to form a two-body bound state.

Hierarchical spline for time series forecasting: An application to Naval ship engine failure rate

description: Predicting equipment failure is important because it could improve availability and cut down the operating budget. Previous literature has attempted to model failure rate with bathtub-formed function, Weibull distribution, Bayesian network, or AHP. But these models perform well with a sufficient amount of data and could not incorporate the two salient characteristics; imbalanced category and sharing structure. Hierarchical model has the advantage of partial pooling. The proposed model is based on Bayesian hierarchical B-spline. Time series of the failure rate of 99 Republic of Korea Naval ships are modeled hierarchically, where each layer corresponds to ship engine, engine type, and engine archetype. As a result of the analysis, the suggested model predicted the failure rate of an entire lifetime accurately in multiple situational conditions, such as prior knowledge of the engine.

description: Η παρούσα εργασία έχει ως θέμα την παιδική λογοτεχνία ως έμμεση πηγή γνώσης για τα ποτάμια συστήματα σε παιδιά σχολικής ηλικίας. Η έρευνα βασίστηκε στα θεωρητικά ευρήματα προηγούμενων ερευνών (ελληνικών και ξένων) για τις εναλλακτικές ιδέες των μαθητών γύρω από τα ποτάμια, από τις οποίες προέκυψε ότι πηγή γνώσης για τους μαθητές δεν είναι μόνο το σχολείο ή/και η άμεση εμπειρία, αλλά και η έμμεση. Σκοπός της εργασίας ήταν να διερευνηθεί εάν η παιδική λογοτεχνία μπορεί να αποτελεί τέτοια έμμεση πηγή γνώσης. Για να απαντηθεί αυτό το βασικό ερώτημα επιλέχθηκαν έξι παιδικά βιβλία με θέμα τα ποτάμια συστήματα τα οποία εξετάστηκαν και αναλύθηκαν για να διαπιστωθεί αν το περιεχόμενο των γεωγραφικών πληροφοριών που περιέχουν μπορεί να οδηγήσει έναν αναγνώστη στη διαμόρφωση επιστημονικών απόψεων ή στη δημιουργία παρανοήσεων. Οι γεωγραφικές αναφορές που εντοπίστηκαν στα κείμενα σχολιάστηκαν και ταξινομήθηκαν σε κατηγορίες, ανάλογα με το περιεχόμενό τους: μη γεωγραφικές αναφορές, λανθασμένες γεωγραφικές αναφορές, χρήση όρων της γεωγραφίας, γεωγραφικές πληροφορίες άμεσες και έμμεσες γεωγραφικές αναφορές, γεωγραφικές γνώσεις. Με βάση τα αποτελέσματα της έρευνας η απλούστευση και ο ανιμισμός είναι τα στοιχεία των παιδικών κειμένων που δύνανται να προκαλέσουν παρανοήσεις, ενώ ο ρεαλισμός και η επιστημονική ακρίβεια βοηθούν στο σχηματισμό γνωστικών σχημάτων.
description: This master thesis questions the influence of children literature as a source of indirect geographical knowledge of rivers. This research was based on the results of previous researches (both Greek and foreign) on student’s misconceptions about rivers. According to these results, children do not receive geographical knowledge only from direct experience or school instruction, but also from indirect experience. The aim of this study was to determine if literature is a means of indirect experience and whether it can deliver geographical knowledge. Therefore, six books were selected to be examined and analyzed in terms of their geographical content. The analysis found seven different types of geographical content in the books: non geographical references, misconceptions, terminology, geographical information, direct geographical references, indirect geographical references, geographical knowledge. According to the research, simplification techniques as well as animism are most probable to lead to misconceptions, whereas realism and scientific accuracy are literature features that might lead to geographical knowledge.

description: The Australia Telescope Hubble Deep Field-South (ATHDFS) survey of the Hubble Deep Field South reaches sensitivities of ~10 miceoJyJy at 1.4, 2.5, 5.2 and 8.7 GHz, making the ATHDFS one of the deepest surveys ever performed with the Australia Telescope Compact Array. Here we present the optical identifications of the ATHDFS radio sources using data from the literature. We find that ~66% of the radio sources have optical counterparts to I = 23.5 mag. Deep HST imaging of the area identifies a further 12% of radio sources. We present new spectroscopic observations for 98 of the radio sources, and supplement these spectroscopic redshifts with photometric ones calculated from 5-band optical imaging. The host galaxy colors and radio-to-optical ratios indicate that low luminosity (or "radio quiet") AGN make up a significant proportion of the sub-mJy radio population, a result which is in accordance with a number of other deep radio studies. The radio-to-optical ratios of the bright (S_1.4GHz > 1 mJy) sources is consistent with a bimodal distribution.

description: Mott insulator plateaus in optical lattices are a versatile platform to study spin physics. Using sites occupied by two bosons with an internal degree of freedom, we realize a uniaxial single-ion anisotropy term proportional to $(S^z)^2$, which plays an important role in stabilizing magnetism for low-dimensional magnetic materials. Here we explore non-equilibrium spin dynamics and observe a resonant effect in the spin anisotropy as a function of lattice depth when exchange coupling and on-site anisotropy are similar. Our results are supported by many-body numerical simulations and are captured by the analytical solution of a two-site model.

description: I present a personal vision of what is essential in the field of neutrino mass, both from the point of view of what has been achieved and what could lie ahead. In the process, I offer a logical, theoretical and phenomenological rationale behind my opinions. It is however neither a summary of what was discussed in the conference nor a party-line viewpoint, rather an attempt to dig through the enormous body of material in our field in order to uncover a common unifying thread. The main focus is on the search for a predictive and self-contained theory of the origin and nature of neutrino mass, with the conclusion that the Left-Right Symmetric Model plays a special role in this aspect.
