description: Η επαγγελματική εξάντληση είναι μια ψυχολογική κατάσταση με σωματικές, συναισθηματικές και διανοητικές διαστάσεις, χαρακτηριζόμενη από συναισθήματα μακροχρόνιας κόπωσης, αρνητικής συμπεριφοράς , απελπισίας, απογοήτευσης και έλλειψης παραγωγικότητας στον εργασιακό τομέα. Η επαγγελματική εξουθένωση ως τομέας είναι ιδιαίτερα γνωστός, ενώ έχει τεκμηριωθεί στη βιβλιογραφία, εγχώρια και διεθνή , ότι οι εκπαιδευτικοί έρχονται αντιμέτωποι με υψηλά επίπεδα στρες και συναισθηματικής εξάντλησης, γεγονός που οδηγεί όχι μόνο σε υψηλά επίπεδα εξουθένωσης αλλά και επαγγελματικής φθοράς. Αντικείμενο της παρούσας μελέτης αποτελεί η εκτίμηση και εξέταση της επίπτωσης της εξουθένωσης σε εκπαιδευτικούς της Δευτεροβάθμιας εκπαίδευσης καθώς και η σχέση που έχει με την αυτοαποτελεσματικότητα τους Για τους σκοπούς αυτής της μελέτης, έπειτα από τη διενέργεια βιβλιογραφικής ανασκόπησης επί του παραπάνω ζητήματος ακολούθησε η ποσοτική διερεύνηση στην οποία επιλέχθηκε ένα δείγμα 134 εκπαιδευτικών από σχολεία του νομού Χαλκιδικής και του νομού Θεσσαλονίκης. Τα αποτελέσματα της έρευνας έδειξαν ότι η αυτοαποτελεσματικότητα αποτελεί προβλεπτικό παράγοντα για την εξουθένωση. Έγινε σαφές πως η επαγγελματική εξουθένωση έχει άμεση σχέση με την αυτό-αποτελεσματικότητα των εκπαιδευτικών. Επιβεβαιώθηκε πως η επαγγελματική εξουθένωση είναι μια κρίση της αυτοαποτελεσματικότητας
description: Occupational exhaustion is a psychological condition with physical, emotional and mental dimensions, characterized by feelings of long-term fatigue, negative behavior, despair, frustration and lack of productivity in the workplace. Burnout as a sector is well known, and it has been documented in the literature, both domestic and international, that teachers experience high levels of stress and emotional exhaustion, which leads to high levels of burnout and deterioration. The object of this study is to assess and examine the impact of burnout on teachers and the relationship between teacher self efficacy and burn out For the purposes of this study, a literature review on the above issue was followed by a quantitative investigation in which a sample of 134 teachers was selected. The results of the survey showed that disengagement is significantly associated with gender. It has become clear that burnout is directly related to a teacher’s self -efficacy. It was confirmed that burn out is a crisis of self-efficacy. In addition , it seems that a teacher’s view on self-efficacy changes at every stage of their career as it is influenced by burn out

description: In this experiment, two-factor 7-level uniform design scheme was applied. Separate treatment of each factor was performed for single effect test. Then, it analyzed the effects of acid and aluminum stress under soilless culture on the water content of plant during the growth of Ginkgo biloba L. seedlings, so as to provide a theoretical basis for studying the connection between plant water and physiological stress. The results showed that the water content of G. biloba plants declined with the decrease of pH, but the water content of G. biloba plants declined with the increase in the concentration of aluminum treatment, indicating that the stronger the acid and aluminum stress, the lower the water content of the plants, affecting the normal absorption of water content of G. biloba plants, accordingly leading to lack of water. According to the analysis of the degree of influence on the water content, pH is the first factor influencing the growth of G. biloba plants. If pH is lower than 3.5, G. biloba plants will not growth, while pH is higher than 5.0, aluminum has no significant effect on the water content of G. biloba plants. In conclusion, the water content of G. biloba plants can be used as an essential indicator for acid and aluminum stress.

description: Small dorsal root ganglion (DRG) neurons are primary nociceptors which are responsible for sensing pain. Elucidation of their dynamics is essential for understanding and controlling pain. To this end, we present a numerical bifurcation analysis of a small DRG neuron model in this paper. The model is of Hodgkin-Huxley type and has 9 state variables. It consists of a Na$\mathrm{_v}$1.7 and a Na$\mathrm{_v}$1.8 sodium channel, a leak channel, a delayed rectifier potassium and an A-type transient potassium channel. The dynamics of this model strongly depends on the maximal conductances of the voltage-gated ion channels and the external current, which can be adjusted experimentally. We show that the neuron dynamics are most sensitive to the Na$\mathrm{_v}$1.8 channel maximal conductance ($\bar{g}_{1.8}$). Numerical bifurcation analysis shows that depending on $\bar{g}_{1.8}$ and the external current, different parameter regions can be identified with stable steady states, periodic firing of action potentials, mixed-mode oscillations (MMOs), and bistability between stable steady states and stable periodic firing of action potentials. We illustrate and discuss the transitions between these different regimes. We further analyze the behavior of MMOs. Within this region, bifurcation analysis shows a sequence of isolated periodic solution branches with one large action potential and a number of small amplitude peaks per period. A closer inspection reveals more complex concatenated MMOs in between these periodic MMOs branches, forming Farey sequences. Lastly, we also find small solution windows with aperiodic oscillations, which seem to be chaotic. The dynamical patterns found here as a function of different parameters contain information of translational importance as their relation to pain sensation and its intensity is a potential source of insight into controlling pain.

description: We devise an approach to measure the polarization of nuclear spins via conductance measurements. Specifically, we study the combined effect of external magnetic field, nuclear spin polarization, and Rashba spin-orbit interaction on the conductance of a quantum wire. Nonequilibrium nuclear spin polarization affects the electron energy spectrum making it time-dependent. Changes in the extremal points of the spectrum result in time-dependence of the conductance. The conductance oscillation pattern can be used to obtain information about the amplitude of the nuclear spin polarization and extract the characteristic time scales of the nuclear spin subsystem.

Synchronization and spatial patterns in forced swarmalators

description: Swarlamators are particles capable of synchronize and swarm. Here we study the effects produced by an external periodic stimulus over a system of swarmalators that move in two dimensions. When the particles are fixed and interact with equal strength (Kuramoto oscillators) their phases tend to synchronize and lock to the external stimulus if its intensity is sufficiently large. Here we show that in a system of swarmalators the force also shifts the phases and angular velocities leading to synchronization with the external frequency. However, the correlation between phase and spatial location decreases with the intensity of the force, going to zero in what appears to be a second order phase transition. In the regime of zero correlation the particles form a static symmetric circular distribution, following a simple model of aggregation. Interestingly, for intermediate values of the force intensity, a different pattern emerges, with the particles splitting in two clusters centered at opposite sides of the stimulus' location, breaking the radial symmetry. The two-cluster pattern is stable and active, with the clusters slowly rotating around the source while exchanging particles.

description: Within the boundaries of this master thesis, a series of machine learning algorithms and techniques are studied and analyzed. There is also a brief presentation of the categories in which machine learning algorithms can be divided, depending on certain criteria. At first the two-population discrimination problem is presented. In the case where there is no information about the underlying distribution and the probability density function, among parzen windows and closest neighbor, the latter is chosen for analysis. The way the K-Nearest Neighbors algorithm works is studied and its error boundaries. The next algorithm that is studied in this project is the decision tree. Different algorithms of decision tree growth techniques are presented and the formation of ensemble methods using decision trees (random forest). Finally, there is a comparison of the biological versus the artificial neuron and the function of the perceptron as a replica of the biological neuron

description: Spitzer observations of the young star CoKuTau/4 reveal a disk with a 10 AU hole that is most likely caused by a newly formed planet. Assuming that the planet opened a gap in the viscous disk, we estimate that the planet mass is greater than 0.1 Jupiter masses. This estimate depends on a lower limit to the disk viscosity derived from the time scale needed to accrete the inner disk, creating the now detectable hole. The planet migration time scale must at least modestly exceed the time for the spectrally inferred hole to clear. The proximity of the planet to the disk edge implied by our limits suggests that the latter is perturbed by the nearby planet and may exhibit a spiral pattern rotating with the planet. This pattern might be resolved with current ground based mid-infrared cameras and optical cameras on the Hubble Space Telescope. The required sub-Myr planet formation may challenge core accretion formation models. However, we find that only if the planet mass is larger than about 10 Jupiter masses, allowing for a high enough surface density without inducing migration, would formation by direct gravitational instability be possible.

description: This letter presents a novel radar based, single-frame, multi-class detection method for moving road users (pedestrian, cyclist, car), which utilizes low-level radar cube data. The method provides class information both on the radar target- and object-level. Radar targets are classified individually after extending the target features with a cropped block of the 3D radar cube around their positions, thereby capturing the motion of moving parts in the local velocity distribution. A Convolutional Neural Network (CNN) is proposed for this classification step. Afterwards, object proposals are generated with a clustering step, which not only considers the radar targets' positions and velocities, but their calculated class scores as well. In experiments on a real-life dataset we demonstrate that our method outperforms the state-of-the-art methods both target- and object-wise by reaching an average of 0.70 (baseline: 0.68) target-wise and 0.56 (baseline: 0.48) object-wise F1 score. Furthermore, we examine the importance of the used features in an ablation study.

Generalized disformal coupling leads to spontaneous tensorization

description: We show that gravity theories involving disformally transformed metrics in their matter coupling lead to spontaneous growth of various fields in a similar fashion to the spontaneous scalarization scenario in scalar-tensor theories. Scalar-dependent disformal transformations have been investigated in this context, and our focus is understanding the transformations that depend on more general fields. We show that vector-dependent disformal couplings can be obtained in various different ways, each leading to spontaneous vectorization as indicated by the instabilities in linearized equations of motion. However, we also show that spontaneous growth is not evident beyond vectors. For example, we could not identify a spontaneous growth mechanism for a spinor field through disformal transformations, even though there is a known example for conformal transformations. This invites further work on the fundamental differences between the two types of metric transformations. We argue that our results are relevant for observations in strong gravity such as gravitational wave detections due to their promise of large deviations from general relativity in this regime.

description: We propose, within a perturbative string theory example, a cosmological way to generate a large hierarchy between the observed Planck mass and the fundamental string scale. Time evolution results in three large space dimensions, one additional dimension transverse to our world and five small internal dimensions with a very slow time evolution. The evolution of the string coupling and internal space generate a large Planck mass. However due to an exact compensation between the time evolution of the internal space and that of the string coupling, the gauge and Yukawa couplings on our Universe are time independent.

description: We analyze the dynamics of an algorithm for approximate inference with large Gaussian latent variable models in a student-teacher scenario. To model nontrivial dependencies between the latent variables, we assume random covariance matrices drawn from rotation invariant ensembles. For the case of perfect data-model matching, the knowledge of static order parameters derived from the replica method allows us to obtain efficient algorithmic updates in terms of matrix-vector multiplications with a fixed matrix. Using the dynamical functional approach, we obtain an exact effective stochastic process in the thermodynamic limit for a single node. From this, we obtain closed-form expressions for the rate of the convergence. Analytical results are excellent agreement with simulations of single instances of large models.

We then turn to the small anisotropy limit, in which we use field theory methods to obtain exact results. We discuss the relevance of our results to Neutron scattering experiments on the 1D Heisenberg chain compound ${\rm Cs_2CoCl_4}$.

description: In recent years a new window on galaxy evolution opened, thanks to the increasing discovery of galaxies with a low surface brightness, such as Ultra Diffuse Galaxies (UDGs). The formation mechanism of these systems is still a much debated question, and so are their kinematical properties. In this work, we address this topic by analyzing the stellar kinematics of isolated UDGs formed in the hydrodynamical simulation suite NIHAO. We construct projected line-of-sight velocity and velocity dispersion maps to compute the projected specific angular momentum, $λ_{\rm R}$, to characterize the kinematical support of the stars in these galaxies. We found that UDGs cover a broad distribution, ranging from dispersion to rotation supported galaxies, with similar abundances in both regimes. The degree of rotation support of simulated UDGs correlates with several properties such as galaxy morphology, higher HI fractions and larger effective radii with respect to the dispersion supported group, while the dark matter halo spin and mass accretion history are similar amongst the two populations. We demonstrate that the alignment of the infalling baryons into the protogalaxy at early $z$ is the principal driver of the $z$=0 stellar kinematic state: pressure supported isolated UDGs form via mis-aligned gas accretion while rotation supported ones build-up their baryons in an ordered manner. Accounting for random inclination effects, we predict that a comprehensive survey will find nearly half of field UDGs to have rotationally supported stellar disks.

Year: 1978
Subjects: Risk and Uncertainty

description: Durable asset replacement theory typically assumes (1) a constant conversion rate between the stock of the asset and its flow of services and (2) perfectly substitutable services from either asset. A methodology is presented which relaxes both assumptions. The variable usage rate for the asset becomes an important determinant of replacement.

description: We discuss the possibility of producing a significant fraction of dark matter in the form of primordial black holes in the context of the pre-big bang inflationary scenario. We take into account, to this purpose, the enhancement of curvature perturbations possibly induced by a variation of the sound-speed parameter $c_s$ during the string phase of high-curvature inflation. After imposing all relevant observational constraints, we find that the considered class of models is compatible with the production of a large amount of primordial black holes in the mass range relevant to dark matter, provided the sound-speed parameter is confined in a rather narrow range of values, $0.003 < c_s < 0.01$.

description: We describe direct electrical measurements of microwave-frequency dynamics in individual nanomagnets that are driven by spin transfer from a DC spin-polarized current. We map out the dynamical stability diagram as a function of current and magnetic field, and we show that spin transfer can produce several different types of magnetic excitations, including small-angle precession, a more complicated large-angle motion, and a high-current state that generates little microwave signal. The large-angle mode can produce a significant emission of microwave energy, as large as 40 times the Johnson-noise background.

description: Motivated by the experimental observation that superconductivity in bulk doped SrTiO$_{3}$ is enhanced as a putative ferroelectric quantum critical point (FE-QCP) is approached, we study the pairing instability of a cubic system in which electrons exchange low-energy ferroelectric fluctuations. Instead of the gradient coupling to the lattice distortion associated with ferroelectricity, we consider a direct coupling between the electrons and the bosonic ferroelectric field that appears in the presence of spin-orbit coupling. Working in the weak-coupling regime, we find that the pairing interaction is dominated by the soft transverse optical (TO) mode, resulting in a $T_{c}$ enhancement upon approaching the FE-QCP. Focusing on even-parity states, we find that although the $s$-wave state always wins, states with higher Cooper-pair angular momentum become close competitors as the TO mode softens. We show that the cubic anisotropy of the FE fluctuations mixes the $s$-wave and $g$-wave states, resulting in a characteristic anisotropy of the gap function. The gap anisotropy behaves non-monotonically as the FE-QCP is approached: upon decreasing the TO mode frequency, the gap anisotropy first changes sign and then increases in magnitude. We discuss the possible applications of our results to the superconducting state of SrTiO$_{3}$.

Hydrocarbon Dust Absorption in Seyfert Galaxies and ULIRGs

description: We present new spectroscopic observations of the 3.4 micron absorption feature in the Seyfert galaxies, NGC1068 and NGC7674, and the ultraluminous infrared galaxy, IRAS08572+3915. A signature of C-H bonds in aliphatic hydrocarbons, the 3.4 micron feature indicates the presence of organic material in Galactic and extragalactic dust. Here we compare the 3.4 micron feature in all the galaxies in which it has been detected. In several cases, the signal-to-noise ratio and spectral resolution permit a detailed examination of the feature profile, something which has rarely been attempted in extragalactic lines of sight. The 3.4 micron band in these galaxies closely resembles that seen in the Galactic diffuse ISM and in newly-formed dust in a protoplanetary nebula. The similarity implies a common carrier for the carbonaceous component of dust, and one which is resistant to processing in the interstellar and/or circumnuclear medium. We also examine the mid-IR spectrum of NGC1068, because absorption bands in the 5-8 micron region further constrain the chemistry of the 3.4 micron band carrier. While weak features like those present in the mid-IR spectrum of diffuse dust towards the Galactic center would be undetectable in NGC1068, the strong bands found in the spectra of many proposed dust analog materials are clearly absent, eliminating certain candidates and production mechanisms for the carrier. The absence of strong absorption features at 5-8 microns is also consistent with the interpretation that the similarity in the 3.4 micron feature in NGC1068 to that in Galactic lines of sight reflects real chemical similarity in the carbonaceous dust.

description: Major economic problems of rural areas over the last three decades stemmed importantly from the large supply and low real price for energy and energy-related inputs. These problems were not analyzed and modeled as specific energy problems because the energy component was a small part of a broader economic and social system. It was impossible to isolate and quantitatively identify the impact of energy supplies and prices per se. It also is likely that high energy prices in the future will have economic impacts which are so broad that quantification of energy effects will be difficult.

description: Many economic impacts are of interest in analyzing an energy scenario. It would be useful to have a set of models to estimate the effect of an energy scenario on: (1) the prices farmers pay for purchased inputs; (2) the impact at the farm firm level on the product mix, systems of production and income level by size of firm; (3) the regional distribution of production; (4) regional employment and income levels; (5) the supply-demand balance for agricultural products and the resulting food prices; (6) the major environmental effects; (7) the impact on the structure of the agricultural industry; (8) the quantities of alternative types of energy used on farms and in other parts of the food and fiber system; and (9) the effect on other sectors of the economy. Furthermore, the model (s) should trace these effects through time rather than comparing the current situation with the static equilibrium at some future time.

description: Η μελέτη εξετάζει το ιδιαίτερα επίκαιρο και νεοπαγές αδίκημα της παραβίασης των διατεταγμένων μέτρων για την πρόληψη ασθενειών, όπως αυτό τυποποιείται στο άρθρο 285 του Ποινικού Κώδικα μετά την έναρξη ισχύος τουνόμου 4619/2019. Το αδίκημα αυτό στη βασική του μορφή ανήκει στην κατηγορία των εγκλημάτων διακινδύνευσης και για το λόγο αυτό μελετάται αρχικά η έννοια του κινδύνου στα εγκλήματα διακινδύνευσης.Παράλληλα,η μελέτη ερευνά τηνέννοια του κοινού κινδύνου,διότι το αδίκηματου άρθρου 285 ΠΚ αποτελεί ένα κοινώς επικίνδυνο έγκλημα. Μετά την ανάλυση των κρίσιμων αυτών εννοιών και την παράθεση των σχετικών απόψεων της θεωρίας και της νομολογίας, παρουσιάζεται σε όλο του το εύρος το αδίκημα του άρθρου 285 ΠΚ και προτείνονται λύσεις για την αντιμετώπιση ορισμένων πιθανών ερμηνευτικών ζητημάτων, τα οποία θα ανακύψουν στο μέλλον
description: The study discusses the extremely topical and newly established crime of infringement of the ordered measures for the prevention of diseases, as it is standardized in Article 285 of the Criminal Code after the entry into force of Law 4619/2019. This offense in its basic form belongs to the category of crimes of endangerment and therefore the meaning of the danger in crimes of endangerment is initially studied. At the same time, the study addresses the meaning of common danger, because the offense of article 285 CC is considered as a crime of common danger. After analyzing these crucial terms and the exposition of the relevant views of legal theory and jurisprudence, the crime of Article 285 CC is discussed in its entirety and solutions are proposed to address some potential interpretative issues that will arise in the future

description: We identify a novel mechanism to read out a single solid-state electron spin using an all-electrical spin-to-charge conversion in a closed system. Our scheme uses three donors and two electron spins, one spin is the qubit, the other is a reference. The population in the third, originally ionized, donor is monitored with an electrometer. Energy-dependent tunnelling of the reference spin to the ionized donor is used to determine the state of the qubit. In contrast to previous methods [e.g., B.E. Kane, Nature (London), \textbf{393}, 133 (1998)] we avoid double electron occupancy of any site within the system, thereby eliminating the possibility of unwanted electron loss from the system. The single spin readout scheme described here is applicable to both electron and nuclear spin based quantum computer architectures.
