description: Τα τελευταία χρόνια, εφαρμογές με επίκεντρο τα δεδομένα, όπως ροές βίντεο υψηλής ευκρίνειας, η κοινωνική δικτύωση και το cloud computing σε συνδυασμό με τη μεγάλη διάδοση κινητών συσκευών όπως τα smartphones και τα tablet έχουν συμβάλει στην ταχεία ανάπτυξη της κίνησης στο Διαδίκτυο. Τα κέντρα δεδομένων αποτελούν μία αναπόσπαστη απόρροια της ύπαρξης του Διαδικτύου και παρέχουν ποικίλες υπηρεσίες από την κοινωνική δικτύωση έως τους επιστημονικούς υπολογισμούς μεγάλης κλίμακας. Επιπρόσθετα, τα τρέχοντα συστήματα κέντρων δεδομένων οργανώνονται με τη μορφή της ιεραρχικής δενδρικής δομής που βασίζεται σε μεταγωγείς περιορισμένου εύρους ζώνης. Τα σύγχρονα συστήματα κέντρων δεδομένων αντιμετωπίζουν μια σειρά ζητημάτων όπως η υψηλή κατανάλωση ενέργειας, η περιορισμένη διαθεσιμότητα εύρους ζώνης, η συνδεσιμότητα διακομιστή, η ενεργειακή απόδοση και το κόστος, η πολυπλοκότητα της κυκλοφορίας κ.λπ. Λόγω της προόδου στους πολυπύρηνους επεξεργαστές, τους επιταχυντές και τα αυξανόμενα επίπεδα παραλληλισμού σε όλα τα επίπεδα του ιεραρχικού συστήματος, παρατηρείται μία έντονη τάση βελτίωσης της απόδοσης που αναμένεται να συνεχιστεί και στα επόμενα χρόνια. Ως εκ τούτου, τα κέντρα δεδομένων πρέπει να επανεξεταστούν από την άποψη του σχεδιασμού διασύνδεσης όσων αφορά την υποστήριξη κέντρων δεδομένων πολύ μεγάλης κλίμακας, εξοικονομώντας παράλληλα ενέργεια. Το τελευταίο διάστημα, πολλοί ερευνητές επικεντρώθηκαν στην εξέταση διαφόρων προσεγγίσεων για την αντιμετώπιση των απαιτήσεων επεκτασιμότητας, ταχύτητας και απόδοσης των κέντρων δεδομένων επόμενης γενιάς. Μία από τις πιο εφικτές λύσεις αυτών των ζητημάτων είναι η χρήση τεχνολογιών οπτικής μεταγωγής ή πιο συγκεκριμένα οπτικών δικτύων στον πυρήνα των συστημάτων των κέντρων δεδομένων. Στα πλαίσια υλοποίησης της παρούσας εργασίας θα παρουσιαστεί μια ενδελεχής περιγραφή των σύγχρονων συστημάτων κέντρων δεδομένων και μερικές δημοφιλείς αρχιτεκτονικές οπτικών δικτύων σε δίκτυα κέντρων δεδομένων όπου θα παρουσιάζονται και θα αναλύονται αντίστοιχα τα πλεονεκτήματα και τα μειονεκτήματά της εκάστοτε αρχιτεκτονικής.

Measurements were obtained for three event classes: inelastic, non-single diffractive and events with at least one charged particle in the pseudorapidity interval $|η|<1$. The use of an improved track-counting algorithm combined with ALICE's measurements of diffractive processes allows a higher precision compared to our previous publications.

description: Musculoskeletal pain is a common reason for emergency department (ED) visit by older adults. Outpatient pain management following ED visits in this population is challenging as a result of contraindications to, and side effects from, available therapies. Shared decision-making (SDM) between patients and emergency physicians may improve patient experiences and health outcomes. Among older ED patients with acute musculoskeletal pain, we sought to characterize their desire for involvement in the selection of outpatient analgesics. We also sought to assess the impact of SDM on change in pain at 1 week, patient satisfaction, and side effects.

description: To date, the radial velocity (RV) method has been one of the most productive techniques for detecting and confirming extrasolar planetary candidates. Unfortunately, stellar activity can induce RV variations which can drown out or even mimic planetary signals - and it is notoriously difficult to model and thus mitigate the effects of these activity-induced nuisance signals. This is expected to be a major obstacle to using next-generation spectrographs to detect lower mass planets, planets with longer periods, and planets around more active stars. Enter Gaussian processes (GPs) which, we note, have a number of attractive features that make them very well suited to disentangling stellar activity signals from planetary signals. We present here a GP framework we developed to model RV time series jointly with ancillary activity indicators (e.g. bisector velocity spans, line widths, chromospheric activity indices), allowing the activity component of RV time series to be constrained and disentangled from e.g. planetary components. We discuss the mathematical details of our GP framework, and present results illustrating its encouraging performance on both synthetic and real RV datasets, including the publicly-available Alpha Centauri B dataset.

description: A numerical model for the solar modulation of cosmic rays, based on the solution of a set of stochastic differential equations, is used to illustrate the effects of modifying the heliospheric magnetic field, particularly in the polar regions of the heliosphere. To this end, the dfferences in the modulation brought about by each of three choices for the heliospheric magnetic field, i.e. the unmodified Parker field, the Smith-Bieber modified field, and the Jokipii-Kota modified field, are studied. It is illustrated that both the Jokipii-Kota and Smith-Bieber modifications are effective in modifying the Parker field in the polar regions. In addition, it is argued that the modification of Smith and Bieber is based on observational evidence and has a firm physical basis, while these motivations are lacking in the case of the Jokipii-Kota modification. From a cosmic ray modulation point of view, we found the Smith-Bieber modification to be the most suitable choice for modifying the heliospheric magnetic field. The features and effects of these three modifications are illustrated both qualitatively and quantitatively. It is also shown how the Smith-Bieber modified field can be applied in cosmic ray modulation models to reproduce observational cosmic ray proton spectra from the PAMELA mission during the solar minimum of 2006 - 2009. These results are compared with those obtained in previous studies of this unusual solar minimum activity period and found to be in good qualitative agreement.

description: We theoretically analyze the interactions and decay rates for atoms dressed by multiple laser fields to strongly interacting Rydberg states using a quantum master equation approach. In this framework a comparison of two-level and three-level Rydberg-dressing schemes is presented. We identify a resonant enhancement of the three-level dressed interaction strength which originates from cooperative multiphoton couplings as well as small distance dependent decay rates. In this regime the soft-core shape of the potential is independent of the sign of the bare Rydberg-Rydberg interaction, while its sign can be repulsive or attractive depending on the intermediate state detuning. As a consequence, near-resonant Rydberg dressing in three-level atomic systems may enable the realization of laser driven quantum fluids with long-range and anisotropic interactions and with controllable dissipation.

title: Dipolar-depletion: study of a field-tunable colloid-polymer system
Creators: name: Semwal, Shivani
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: Colloidal gels are an important class of materials with mesoscale building blocks, and they have wide-ranging applications, from water purification to cement to biotechnology. However, the formation of colloidal gels is beset by inadequate control over phase behaviour and slow aging kinetics. In this work, we report on experiments that examine structure, structural relaxation and dynamics in colloid-polymer suspensions, with fine, tunable control: the concentration of non-adsorbing polymer controls the strength of a depletion attraction, and an external electric field induces dipolar interactions that are instantly switchable and tunable in strength. ßWith these switchable interactions, we have studied the “dipolar-depletion” phase diagram in real space via fluorescence confocal laser scanning microscopy. We show combining depletion with dipolar interactions, at lower polymer concentrations, lowers the field threshold for observing ordered sheet-like dipolar structures. At intermediate polymer concentrations, depletion-induced clusters suppress field-induced ordering. At high depletion strengths, we can create partially ordered gel states. We also quantitatively characterize the transition from reversible to irreversible structures, and use the cycling of the external field to accelerate aging in a gel-forming system. For processes that take months or years to study, such as the collapse of certain gels, such accelerated aging would prove extremely useful. In addition, we characterize our model system by measuring the Zeta potential and charge on the colloids that we use to study the phase diagram via both AC and DC microelectrophoresis. We compare AC and DC measurements and find that there is no electrode polarization effect in a partially polar solvent.
From Ambiguity Aversion to a Generalized Expected Utility. Modeling Preferences in a Quantum Probabilistic Framework

description: Ambiguity and ambiguity aversion have been widely studied in decision theory and economics both at a theoretical and an experimental level. After Ellsberg's seminal studies challenging subjective expected utility theory (SEUT), several (mainly normative) approaches have been put forward to reproduce ambiguity aversion and Ellsberg-type preferences. However, Machina and other authors have pointed out some fundamental difficulties of these generalizations of SEUT to cope with some variants of Ellsberg's thought experiments, which has recently been experimentally confirmed. Starting from our quantum modeling approach to human cognition, we develop here a general probabilistic framework to model human decisions under uncertainty. We show that our quantum theoretical model faithfully represents different sets of data collected on both the Ellsberg and the Machina paradox situations, and is flexible enough to describe different subjective attitudes with respect to ambiguity. Our approach opens the way toward a quantum-based generalization of expected utility theory (QEUT), where subjective probabilities depend on the state of the conceptual entity at play and its interaction with the decision-maker, while preferences between acts are determined by the maximization of this 'state-dependent expected utility'.

description: The second generation of interferometric gravitational wave detectors are quickly approaching their design sensitivity. For the first time these detectors will become limited by quantum back-action noise. Several back-action evasion techniques have been proposed to further increase the detector sensitivity. Since most proposals rely on a flexible readout of the full amplitude- and phase-quadrature space of the output light field, balanced homodyne detection is generally expected to replace the currently used DC readout. Up to now, little investigation has been undertaken into how balanced homodyne detection can be successfully transferred from its ubiquitous application in table-top quantum optics experiments to large-scale interferometers with suspended optics. Here we derive implementation requirements with respect to local oscillator noise couplings and highlight potential issues with the example of the Glasgow Sagnac Speed Meter experiment, as well as for a future upgrade to the Advanced LIGO detectors.

Neighborhood-level efforts to alleviate poverty for all children require alignment of cross-sector efforts, community engagement, and multifactorial approaches that consider the role of people as well as place. We highlight several accessible tools and strategies that health practitioners can engage to improve regional and local systems that influence child opportunity. The Child Opportunity Index is a population-level surveillance tool to describe community-level resources and inequities in US metropolitan areas. The case studies reviewed outline strategies for creating higher opportunity neighborhoods for pediatricians interested in working across sectors to address the impact of neighborhood opportunity on child health and well-being.

description: There are numerous examples of radio sources with various sizes which surprisingly exhibit very similar morphology. This observational fact helped to create a standard evolutionary model in which young and small radio-loud active galactic nuclei (AGN) called gigahertz-peaked spectrum (GPS) sources and compact steep spectrum (CSS) sources, become large-scale radio objects. However, many details of this evolutionary process are still unclear. We explored evolution scenarios of radio-loud AGN using new radio, optical and X-ray data of so far unstudied low luminosity compact (LLC) sources and we summarize the results in this paper. Our studies show that the evolutionary track is very 'personalized' although we can mention common factors affecting it. These are interaction with the ambient medium and AGN power. The second feature affects the production of the radio jets which if they are weak are more vulnerable for instabilities and disruption. Thus not all GPS and CSS sources will be able to develop large scale morphologies. Many will fade away being middle-aged (10^5 years). It seems that only radio strong, high excitation compact AGN can be progenitors of large-scale FRII radio sources.

description: The main question studied in this paper concerns the weak-coupling behavior of the geometrically induced bound states of singular Schrödinger operators with an attractive $δ$ interaction supported by a planar, asymptotically straight curve $Γ$. We demonstrate that if $Γ$ is only slightly bent or weakly deformed, then there is a single eigenvalue and the gap between it and the continuum threshold is in the leading order proportional to the fourth power of the bending angle, or the deformation parameter. For comparison, we analyze the behavior of a general geometrical induced eigenvalue in the situation when one of the curve asymptotes is wiggled.

Representations and Implications of Papers Written by E.T. Whittaker in 1903 and 1904
Creators: name: Titleman, Mark
Publisher: name: figshare
Year: 2023
Subjects: Classical physics not elsewhere classified

description: In 1903 and 1904, E.T. Whittaker produced a pair of papers that, although sometimes considered mere mathematical statements (Barrett 1993), held important implications if viewed as physical realities. His 1903 paper united electrostatic and gravitational attraction as both resulting from longitudinal waves in the medium. His 1904 paper specifically dealt with electro- magnetic waves as resulting from the interference of two such longitudinal waves as scalar potential functions. These papers, if representative of physical reality, may have important implications: gravitational lensing, gravitational waves, the Aharonov-Bohm effect, the existence of a hyperspace above or behind normal space, and the elimination of gravitational and point charge singularities.

description: BACKGROUND: Few studies have comprehensively evaluated the effectiveness of multi-faceted interventions intended to improve pedestrian safety. "Watch for Me NC" is a multi-faceted, community-based pedestrian safety program that includes widespread media and public engagement in combination with enhanced law enforcement activities (i.e., police outreach and targeted pedestrian safety operations conducted at marked crosswalks) and low-cost engineering improvements at selected crossings. The purpose of this study was to estimate the effect of the law enforcement and engineering improvement components of the program on motor vehicle driver behavior, specifically in terms of increased driver yielding to pedestrians in marked crosswalks.

METHODS: The study used a pre-post design with a control group, comparing crossing locations receiving enforcement and low-cost engineering treatments (enhanced locations) with locations that did not (standard locations) to examine changes in driver yielding over a 6-month period from 2013 to 2014. A total of 24,941 drivers were observed in 11,817 attempted crossing events at 16 crosswalks in five municipalities that were participating in the program. Observations of real pedestrians attempting to use the crosswalks ("naturalistic" crossing) were supplemented by observations of trained research staff attempting the same crossings following an established protocol ("staged" crossings). Generalized estimating equations (GEE) were used to model driver yielding rates, accounting for repeated observations at the crossing locations and controlling other factors that affect driver behavior in yielding to pedestrians in marked crosswalks.

RESULTS: At crossings that did not receive enhancements (targeted police operations or low-cost engineering improvements), driver yielding rates did not change from before to after the Watch for Me NC program. However, yielding rates improved significantly (between 4 and 7 percentage points on average) at the enhanced locations. This was true for both naturalistic and staged crossings.

CONCLUSIONS: This study provides evidence that enhanced enforcement and low-cost engineering improvements, as a part of a broader program involving community-based outreach, can increase driver yielding to pedestrians in marked crosswalks. These data are important for the staff and decision-makers involved in pedestrian safety programs to gain a better understanding of the different engineering and behavioral mechanisms that could be used to improve driver yielding rates.

description: In the Declarative Networking paradigm, Datalog-like languages are used to express distributed computations. Whereas recently formal operational semantics for these languages have been developed, a corresponding declarative semantics has been lacking so far. The challenge is to capture precisely the amount of nondeterminism that is inherent to distributed computations due to concurrency, networking delays, and asynchronous communication. This paper shows how a declarative, model-based semantics can be obtained by simply using the well-known stable model semantics for Datalog with negation. We show that the model-based semantics matches previously proposed formal operational semantics.

description: It is argued that the classical local inertial frame used to define rotational states of quantum systems is only approximate, and that geometry itself must also be rotationally quantized at the Planck scale. A Lorentz invariant statistical model of correlations in quantum geometry on larger scales predicts spacelike correlations that describe rotational fluctuations in the inertial frame. Fluctuations are estimated to significantly affect the gravity of quantum field states on a macroscopic scale, characterized by the Chandrasekhar radius. It is suggested that the cosmological constant might be a signature of exotic rotational correlations entangled with the strong interaction vacuum, and have a value determined entirely by Planck scale quantum gravity and Standard Model fields.
