description: Οι θάνατοι λόγω υπερβολικής δόσης ψυχοδραστικών ουσιών έχουν αυξηθεί τελευταία, κυρίως λόγω της υψηλής διαθεσιμότητας ισχυρών συνθετικών οπιοειδών, όπως η φεντανύλη και τα χημικά της ανάλογα. Το ποσοστό θνησιμότητας λόγω κατάχρησης των συνθετικών οπιοειδών, εκτός από τη μεθαδόνη, αυξήθηκε κατά 72,2% από το 2014 έως το 2015 και διπλασιάστηκε από το 2015 έως το 2016, τοποθετώντας τις ΗΠΑ στο κέντρο της επιδημίας υπερβολικής δόσης οπιοειδών. Η αναλυτική ταυτοποίηση αυτών των οπιοειδών σε μεταθανάτια δείγματα και η ορθή ερμηνεία των τοξικολογικών δεδομένων είναι καθοριστικής σημασίας για τον εντοπισμό και την εφαρμογή προληπτικών στρατηγικών. Αυτή η εργασία ανασκοπεί στην τρέχουσα γνώση σχετικά με τη μεταθανάτια τοξικολογία των συνθετικών οπιοειδών και τους χημικούς και φαρμακολογικούς παράγοντες που μπορεί να επηρεάσουν τις συγκεντρώσεις των ουσιών αυτών στα διάφορα βιολογικά υλικά που εξετάζονται μεταθανατίως και ως εκ τούτου την ερμηνεία τους.
description: Deaths due to overdose have been increasing lately, mainly due to the wide availability of strong synthetic opioids, such as fentanyl and its chemical analogs. The mortality rate of synthetic opioids, in addition to methadone, increased by 72.2% from 2014 to 2015 and doubled from 2015 to 2016, placing the United States in the middle of the overdose epidemic. The detailed identification of these opioids in postmortem samples and the correct interpretation of the toxicological data are crucial for the detection and implementation of preventive strategies. This paper reviews current knowledge of the postmortem toxicology of synthetic opioids and the chemical and pharmacological factors that may affect drug concentrations in the various postmortem matrices and therefore their interpretation.

description: Collisional fragmentation is a ubiquitous phenomenon arising in a variety of astrophysical systems, from asteroid belts to debris and protoplanetary disks. Numerical studies of fragmentation typically rely on discretizing the size distribution of colliding objects into a large number N of bins in mass space, usually logarithmically spaced. A standard approach for redistributing the debris produced in collisions into the corresponding mass bins results in O(N^3) calculation, which leads to significant computational overhead when N is large. Here we formulate a more efficient explicit O(N^2) fragmentation algorithm, which works when the size spectrum of fragments produced in an individual collision has a self-similar shape with only a single characteristic mass scale (which can have arbitrary dependence on the energy and masses of colliding objects). Fragment size spectra used in existing fragmentation codes typically possess this property. We also show that our O(N^2) approach can be easily extended to work with non-self-similar fragment size distributions, for which we provide a worked example. This algorithm offers a substantial speedup of fragmentation calculations for large N> 100, even over the implicit methods, making it an attractive tool for studying collisionally evolving systems.

description: We examine critically the issue of phase transitions in one-dimensional systems with short range interactions. We begin by reviewing in detail the most famous non-existence result, namely van Hove's theorem, emphasizing its hypothesis and subsequently its limited range of applicability. To further underscore this point, we present several examples of one-dimensional short ranged models that exhibit true, thermodynamic phase transitions, with increasing level of complexity and closeness to reality. Thus having made clear the necessity for a result broader than van Hove's theorem, we set out to prove such a general non-existence theorem, widening largely the class of models known to be free of phase transitions. The theorem is presented from a rigorous mathematical point of view although examples of the framework corresponding to usual physical systems are given along the way. We close the paper with a discussion in more physical terms of the implications of this non-existence theorem.

description: An important problem in physics concerns the analysis of audio time series generated by transduced acoustic phenomena. Here, we develop a new method to quantify the scaling properties of the local variance of nonstationary time series. We apply this technique to analyze audio signals obtained from selected genres of music. We find quantitative differences in the correlation properties of high art music, popular music, and dance music. We discuss the relevance of these objective findings in relation to the subjective experience of music.

description: The double copy relates scattering amplitudes in gauge and gravity theories. It has also been extended to classical solutions, and a number of approaches have been developed for doing so. One of these involves expressing fields in a variety of (super-)gravity theories in terms of convolutions of gauge fields, including also BRST ghost degrees of freedom that map neatly to their corresponding counterparts in gravity. In this paper, we spell out how to use the convolutional double copy to map gauge and gravity solutions in the manifest Lorenz and de Donder gauges respectively. We then apply this to a particular example, namely the point charge in pure gauge theory. As well as clarifying how to use the convolutional approach, our results provide an alternative point of view on a recent discussion concerning whether point charges map to the Schwarzschild solution, or the more general two-parameter JNW solution, which includes a dilaton field. We confirm the latter.

description: Obesity and type 2 diabetes (T2DM) are among the most complicated health problems of the 21st century and are associated with a worrying increase regarding the impact on patients' quality of life. The last decade has seen a growing number of reports describing links between evolution and these two modern disorders. Recent developments in medicine confirm that genetics can be an important step in their treatment so the study of the genetic evolution of these disorders can shed new light on their decoding. In the present work, an attempt was made to record all the current data on the evolution of obesity and T2DM by recording all the hypotheses that suggest different mechanisms of evolution like for example the thrifty genotype hypothesis, the thrifty phenotype hypothesis and others.

description: About 25\% -50\% of white dwarfs (WDs) are found to be polluted by heavy elements. It has been argued that the pollution could be caused by the tidal disruption of an approaching planet around the WD, during which a large number of clumps would be produced and would finally fall onto the WD. The reason that the planet approaches the WD is usually believed to be due to gravitational perturbations from another distant planet or stellar companion. However, the dynamics of the perturbation and the detailed partial disruption process are still poorly understood. In this study, we present an in-depth investigation of these issues. A triple system composed of a WD, an inner orbit planet, and an outer orbit planet is considered. The inner plant would be partially disrupted periodically in the long-term evolution. Fragments generated in the process are affected by the gravitational perturbations from the remnant planet, facilitating their falling toward the WD. The mass loss rate of the inner planet depends on both its internal structure and also on the orbital configuration of the planetary system.

We argue that for weak disorder, the ground state of the theory is not Lifshitz invariant with a non-trivial disorder-dependent dynamical exponent, as previously found. Instead, below a non-perturbatively small energy scale, we predict infrared physics becomes independent of the disorder strength.

description: Knowledge of the energy spectrum of $^8$B neutrinos is an important ingredient for interpreting experiments that detect energetic neutrinos from the Sun. The neutrino spectrum deviates from the allowed approximation because of the broad alpha-unstable $^8$Be final state and recoil order corrections to the beta decay. We have measured the total energy of the alpha particles emitted following the beta decay of $^8$B. The measured spectrum is inconsistent with some previous measurements, in particular with a recent experiment of comparable precision. The beta decay strength function for the transition from $^8$B to the accessible excitation energies in $^8$Be is fit to the alpha energy spectrum using the R-matrix approach. Both the positron and neutrino energy spectra, corrected for recoil order effects, are constructed from the strength function. The positron spectrum is in good agreement with a previous direct measurement. The neutrino spectrum disagrees with previous experiments, particularly for neutrino energies above 12 MeV.

Ακολουθεί κώδικας με χρήση του λογισμικού MATLAB, όπου μελετάται η επίδραση του SNR, της τάξης διαμόρφωσης και του αριθμού των δυαδικών ψηφίων που μεταδίδονται ανά σύμβολο στις τιμές των σφαλμάτων (Bit Error Rate) για σήματα που υφίστανται διαμορφώσεις QPSK, 16-QΑΜ και 64-QAM με δυαδική κωδικοποίηση και με κωδικοποίηση Gray. Ακολουθεί η υλοποίηση των παραπάνω διαμορφώσεων με την εισαγωγή του ψηφιακού φίλτρου squared root raised cosine filter και της επίδρασης του στις μετρήσεις σφαλμάτων. Η ανάγκη για υψηλές ταχύτητες και η συνεχόμενη αύξηση των χρηστών σε συνδυασμό με την ανάγκη για όσο το δυνατόν μικρότερα σφάλματα οδήγησε στην ανάπτυξη των δικτύων 5G. Με τη σύγκριση των προηγούμενων διαμορφώσεων, τονίζεται η εξέλιξη της επικοινωνίας μέσα από την ανάπτυξη των δικτύων 5ης γενιάς. Μετά από κάθε υλοποίηση γίνεται παρουσίαση των βασικών διαγραμμάτων αστερισμού και σημαντικών τιμών σφάλματος καθώς και επεξήγηση των αποτελεσμάτων.
description: The aim of this master thesis is the theoretical study and the code implementation of advanced modulation techniques and their waveforms. Firstly, a bibliographic review of the basic technologies of wireless communication are presented. After that, there is a theoritical presentation of QPSK, QAM and OFDM modulation techniques. Afterwards, through a MATLAB implementation code the effect of SNR, modulation class and the number of bits that are transmitted per symbol on the Bit Error Rates (BER) values on signals with QPSK, 16-QAM and 64-QAM for binary and gray coding are examined. Consequently, a digital filter called squared-root raised cosine filter is implemented and its effect on each modulation scheme is also examined. The need for high data rates and the continued growth of users combined with the necessity for minimum error rates resulted in the development of 5G. The results of the above modulation schemes show the progress of communication through 5G networks. After each implementation the basic constellation diagrams, some important BER values and the explanation of them are presented.

description: The recombination rate for three identical bosons has been calculated to test the limits of its universal behavior. It has been obtained for several different collision energies and scattering lengths (a) up to 10^5 a.u., giving rates that vary over 15 orders of magnitude. We find that universal behavior is limited to the threshold region characterized by E lesssim hbar^2/(2mu_{12}a^2), where E is the total energy and mu_{12} is the two-body reduced mass. The analytically predicted infinite series of resonance peaks and interference minima is truncated to no more than three of each for typical experimental parameters.

description: The Silicon photomultiplier-based Compton Telescope for Safety and Security (SCoTSS) has been developed incorporating end-user requirements into the design process. The end-user group includes those responsible for mobile survey in the event of a radiological or nuclear accident, those responsible for radiation survey support to security operations at major events and at Canadian borders, as well as some of those responsible for Canadian defense applications. The SCoTSS development program has reached a technology readiness level of eight, and we are proceeding with field trials of the instrument in high-fidelity operational environments. Prospective end users have been involved in trial set up and execution, assuring applicability in their mission spaces. SCoTSS has been subject to trials involving hidden sources, heavily shielded sources, imager moving with respect to source, and complicated man-made surroundings. Our operators value high sensitivity for anomaly geolocation and mapping. End users also require an instrument which is capable of direction reconstruction in motion, as well as rapid imaging of a field of view. We have developed a "time to image" measure which allows for quantitative comparison of imagers of fundamentally different technology, where one design may have an advantage in terms of energy resolution and compactness and another design may have an advantage in terms of efficiency and cost effectiveness. We present here the performance of the SCoTSS imager in rapid direction finding. As well, we compare the time to image quantity for the SCoTSS imager and the H3D Polaris-H Quad imager where the data were taken under equivalent conditions. This quantitative measure of imaging performance can allow operators to make an informed choice of the design that meets their needs taking into consideration also weight and size as well as budgetary constraints.

Tablet-adapted measures provide an efficient, accurate method of data collection for large-scale studies. The Castles and Coltheart Reading Test 2 (CC2) is a standardized paper- and-pencil measure of children's reading ability. In the current study, the CC2 was administered to 603 children aged 7-8 years via iPad using electronic data capture software. Results indicate the tablet-adapted measure could be reliably administered by non-clinical staff and showed quantitative equivalence, i.e., comparable score distributions, to CC2 normative data. Internal consistency was good for regular and non-word lists. Findings suggest that the tablet-adapted CC2 is a viable tool for large research studies.

description: Chemicals, derived from pharmaceuticals and personal hygiene items, used daily by all of us end up in lakes, rivers, streams, groundwater aquifers and, possibly, drinking water through sewers and sewage treatment plants, as well as landfills. Until very recently chemical diagnostic technology was not able to detect these substances in water because the concentrations were below the detectable limits. Now that parts per trillion (ppt) or nanograms per liter (ng / L) can be detected, one or more of these chemicals are often detected in water in various parts of the world. Even though these concentrations seem very small to insignificant, their effect on our health and the environment is still under investigation. On the occasion of the spread of COVID-19 in Greece, and in the context of the research on how many pharmaceuticals, personal hygiene items, detergents and disinfectants end up in the sewerage network, a questionnaire was formed to draw conclusions about the role that a pandemic can play, such as the one examined in this research.

description: We unravel the correlation effects of the second-order quantum phase transitions emerging on the ground state of a harmonically trapped spin-1 Bose gas, upon varying the involved Zeeman terms, as well as its breathing dynamics triggered by quenching the trapping frequency. It is found that the boundaries of the associated magnetic phases are altered in the presence of interparticle correlations for both ferromagnetic and anti-ferromagnetic spin-spin interactions, an effect which becomes more prominent in the few-body scenario. Most importantly, we unveil a correlation-induced shrinking of the anti-ferromagnetic and broken-axisymmetry phases implying that ground states with bosons polarized in a single spin-component are favored. Turning to the dynamical response of the spinor gas it is shown that its breathing frequency is independent of the system parameters while correlations lead to the formation of filamentary patterns in the one-body density of the participating components. The number of filaments is larger for increasing spin-independent interaction strengths or for smaller particle numbers. Each filament maintains its coherence and exhibits an anti-correlated behavior while distinct filaments show significant losses of coherence and are two-body correlated. Interestingly, we demonstrate that for an initial broken-axisymmetry phase an enhanced spin-flip dynamics takes place which can be tuned either via the linear Zeeman term or the quench amplitude.

description: A new installment of neutral hydrogen mappings of Blue Compact Dwarf galaxies, as defined by optical morphology, in and near the Virgo cluster is presented. The primary motivation was to search for outlying clouds of HI as potential interactive triggers of the enhanced star formation, and therefore the mapped galaxies were selected for large HI} mass, large optical diameter, and large velocity profile width. Approximately half the sample proved to have one or more small, low column density star-free companion clouds, either detached or appearing as an appendage in our maps, at resolution of order 4 kpc. Comparison is made to a sample of similarly mapped field BCD galaxies drawn from the literature; however, the Virgo cluster sample of mapped BCDs is still too small for conclusive comparisons to be made. We found, on the one hand, little or no evidence for ram pressure stripping nor, on the other, for extremely extended low column density HI envelopes. The HI rotation curves in most cases rise approximately linearly, and slowly, as far out as we can trace the gas.

Winning combination or strange brew? : exploring a merged concept of distributed leadership in New Zealand elementary school numeracy reform
Creators: name: DeAbreu, Robert J.

description: Distributed leadership is a relatively recent, promising branch in educational leadership research (Hartley, 2010). Leithwood states that qualitative research, rather than quantitative, allows us to unpack the contextual nuances that make distributed leadership differentially effective (Leithwood, 2001). In looking at the case of distributed leadership in numeracy reform at a school in New Zealand, Higgins and Bonne’s qualitative approach allows them to examine more deeply the root causes of the effectiveness of distributed leadership in this particular context. As part of their findings, they merge Gronn’s concept of the hybrid nature of leadership, the fact that leaders use a mixture of leadership styles and tools (Gronn, 2009), with Leithwood’s four core functions of leadership (Leithwood et al., 2007) to create, I will argue, a cohesive and flexible framework of distributed leadership. This paper will explore the soundness of this merged leadership model and the possibility of its application in other contexts.

description: A (second) quiescent region about N ≈ t/π is observed for the Riemann Zeta Dirichlet series sum inside the critical strip. The zeroth order sum based on t/π provides a much closer estimates of ζ(s) than the zeroth order Riemann-Siegel Z formula results (which itself uses the first quiescent region about sqrt(t/(2π)). The quiescent region is present for the whole range 0 ≤ σ ≤ 1 but the error is higher as σ → 0.
Charge density wave sliding driven by an interplay of conventional and Hall voltages in NbSe$_3$ microbridges

description: Collective charge-density wave (CDW) transport was measured under a high magnetic field in NbSe$_3$ microbridges which have been cut transversely and at an angle to the chains' direction. We give evidences that the CDW sliding is driven by the Hall voltage generated by the inter-chain current of normal carriers. We have discovered a re-entrance effect of the Hall-driven sliding above a crossover temperature at which the Hall constant has been known to change sign. For the narrow channel, cut at 45$^\circ$ relative to the chain axis, we observed an evolution from the Hall-driven sliding at low temperatures, to the conventional sliding at higher temperatures, which corroborates with falling of the Hall constant. In this course, the nonlinear contribution to the conductivity coming from the collective sliding changes sign. The quantization of Shapiro-steps, generated presumably by a coherent sequence of phase slips, indicates that their governing changes from the applied voltage to the current.

Introduction Over 310 000 women gave birth in Australia in 2016, with approximately 80 000 births in the state of Victoria. While most of these births occur in metropolitan Melbourne and other large regional centres, a significant proportion of Victorian women birth in local rural health services. The Victorian state government recently mandated the provision of a maternal and neonatal emergency training programme, called Maternal and Newborn Emergencies (MANE), to rural and regional maternity service providers across the state. MANE aims to educate maternity and newborn care clinicians about recognising and responding to clinical deterioration in an effort to improve clinical outcomes. This paper describes the protocol for an evaluation of the MANE programme. Methods and analysis This study will evaluate the effectiveness of MANE in relation to: clinician confidence, skills and knowledge; changes in teamwork and collaboration; and consumer experience and satisfaction, and will explore and describe any governance changes within the organisations after MANE implementation. The Kirkpatrick Evaluation Model will provide a framework for the evaluation. The participants of MANE, 27 rural and regional Victorian health services ranging in size from approximately 20 to 1000 births per year, will be invited to participate. Baseline data will be collected from maternity service staff and consumers at each health service before MANE delivery, and at four time-points post-MANE delivery. There will be four components to data collection: a survey of maternity services staff; follow-up interviews with Maternity Managers at health services 4 months after MANE delivery; consumer feedback from all health services collected through the Victorian Healthcare Experience Survey; case studies with five regional or rural health service providers. Ethics and dissemination This evaluation has been approved by the La Trobe University Science, Health and Engineering College Human Ethics Sub-Committee. Findings will be presented to project stakeholders in a deidentified report, and disseminated through peer-reviewed publications and conference presentations.
Long-range Charger transfer in DNA through Polaron Diffusion

description: Recent experimental evidence shows that the pi-orbitals along the stacking of base pairs can facilitate the long-range charge transfer in DNA. Proton motion in the base pair hydrogen bonds has also been found to affect the transfer rate. To explain this behavior we propose a model considering interactions of doped charges with hydrogen bonds and vibrations in DNA. The charge trapped by either protons or vibrations can cause structural distortions leading to polaron formation. By further considering polaron diffusion in DNA we find that the charge transfer rate derived from the diffusion coefficient is in agreement with the experimental results.

description: Strongly correlated quantum solids are characterized by an inherently granular electronic fabric, with spatial patterns that can span multiple length scales in proximity to a critical point. Here, we used a resonant magnetic X-ray scattering nanoprobe with sub-100 nm spatial resolution to directly visualize the texture of antiferromagnetic domains in NdNiO$_3$. Surprisingly, our measurements revealed a highly textured magnetic fabric, which is shown to be robust and nonvolatile even after thermal erasure across its ordering ($T_{N\acute{e}el}$) temperature. The scale-free distribution of antiferromagnetic domains and its non-integral dimensionality point to a hitherto-unobserved magnetic fractal geometry in this system. These scale-invariant textures directly reflect the continuous nature of the magnetic transition and the proximity of this system to a critical point. The present study not only exposes the near-critical behavior in rare earth nickelates but also underscores the potential for novel X-ray scattering nanoprobes to image the multiscale signatures of criticality near a critical point.

Effects of Helium Phase Separation on the Evolution of Giant Planets

description: We present the first models of Saturn and Jupiter to couple their evolution to both a radiative-atmosphere grid and to high-pressure phase diagrams of hydrogen with helium. The purpose of these models is to quantify the evolutionary effects of helium phase separation in Saturn's deep interior. We find that prior calculated phase diagrams in which Saturn's interior reaches a region of predicted helium immiscibility do not allow enough energy release to prolong Saturn's cooling to its known age and effective temperature. We explore modifications to published phase diagrams that would lead to greater energy release, and find a modified H-He phase diagram that is physically reasonable, leads to the correct extension of Saturn's cooling, and predicts an atmospheric helium mass fraction Y_atmos in agreement with recent estimates. We then expand our inhomogeneous evolutionary models to show that hypothetical extrasolar giant planets in the 0.15 to 3.0 Jupiter mass range may have T_effs 10-15 K greater than one would predict with models that do not incorporate helium phase separation.

description: Η προτίμηση χεριού αποτελεί έναν από τους δείκτες της λειτουργικής εγκεφαλικής ασυμμετρίας. Ιδιαίτερη προσοχή έχει δοθεί από τους ερευνητές στην αξιολόγησή της. Η πιο χρησιμοποιούμενη μέθοδος για τη μέτρησή της είναι τα δομημένα ερωτηματολόγια. Οι ερευνητές βρίσκονται σε διαρκή αναζήτηση τέτοιων αξιόπιστων και έγκυρων μεθόδων που να διαθέτουν και οικολογική εγκυρότητα. Σκοπός της συγκεκριμένης εργασίας ήταν η ανάπτυξη ενός σύγχρονου και καινοτόμου ερωτηματολογίου προτίμησης χεριού που να ανταποκρίνεται στις τεχνολογικές εξελίξεις της σύγχρονης κοινωνίας. Στην παρούσα εργασία έλαβαν μέρος συνολικά 300 άτομα, 144 μαθητές και 156 μαθήτριες, τυπικής ανάπτυξης, που φοιτούσαν σε δημόσια σχολεία, Γυμνάσια και Λύκεια της Περιφερειακής Ενότητας Πέλλας (Μ.Ο. 15,09, Τ.Α. 1,30). Τα αποτελέσματα έδειξαν ότι υπάρχει σημαντική διαφορά στον τρόπο αξιολόγησης της προτίμησης χεριού μεταξύ του ερωτηματολογίου των Briggs και Nebes (1975) και του νέου προτεινόμενου ερωτηματολογίου. Η συχνότητα εκτέλεσης των περισσότερων έργων που προτείνονται από τους Briggs και Nebes (1975) είναι σημαντικά χαμηλότερη σε σχέση με αυτά που προτείνονται στο νέο ερωτηματολόγιο. Συμπερασματικά, προκύπτει ότι για τη συγκεκριμένη ηλικιακή ομάδα το νέο προτεινόμενο ερωτηματολόγιο αποτελεί μια πιο έγκυρη και αξιόπιστή μέθοδο μέτρησης της προτίμησης χεριού. Γίνεται συζήτηση των ευρημάτων από διαγνωστική και μεθοδολογική σκοπιά.
description: Handedness is one of the indicators of functional brain asymmetry. Special attention has been paid by researchers to its evaluation. The most commonly used method for measuring is the structured questionnaires. Researchers are constantly searching for such reliable and valid methods that have ecological validity. The purpose of this study was to develop a modern and innovative hand preference questionnaire adapted to the technological developments of modern society. In the present study took part a total of 300 people, 144 male students and 156 female students of typical development, who attend public schools, Gymnasiums and Lyceums of the Regional Unit of Pella (M.O. 15.09, T.A. 1.30). The results showed that there was a significant difference in the way hand preference was assessed between the Briggs and Nebes (1975) questionnaire and the new proposed questionnaire. The execution rate of most of the items proposed by Briggs and Nebes (1975) is significantly lower than that of the items proposed in the new questionnaire. In conclusion, it appears that for the specific age group the new proposed questionnaire is a more valid and reliable method of measuring hand preference. The findings are discussed from a diagnostic and methodological point of view.

Tablet-adapted measures provide an efficient, accurate method of data collection for large-scale studies. The Castles and Coltheart Reading Test 2 (CC2) is a standardized paper- and-pencil measure of children's reading ability. In the current study, the CC2 was administered to 603 children aged 7-8 years via iPad using electronic data capture software. Results indicate the tablet-adapted measure could be reliably administered by non-clinical staff and showed quantitative equivalence, i.e., comparable score distributions, to CC2 normative data. Internal consistency was good for regular and non-word lists. Findings suggest that the tablet-adapted CC2 is a viable tool for large research studies.
