description: We propose a general method to embed target states into the middle of the energy spectrum of a many-body Hamiltonian as its energy eigenstates. Employing this method, we construct a translationally-invariant local Hamiltonian with no local conserved quantities, which does not satisfy the eigenstate thermalization hypothesis. The absence of eigenstate thermalization for target states is analytically proved and numerically demonstrated. In addition, numerical calculations of two concrete models also show that all the energy eigenstates except for the target states have the property of eigenstate thermalization, from which we argue that our models thermalize after a quench even though they does not satisfy the eigenstate thermalization hypothesis.

description: In this paper, we propose a novel approach to obtaining a reliable and simple mathematical model of a dielectrophoretic force for model-based feedback micromanipulation. Any such model is expected to sufficiently accurately relate the voltages (electric potentials) applied to the electrodes to the resulting forces exerted on microparticles at given locations in the workspace. This model also has to be computationally simple enough to be used in real time as required by model-based feedback control. Most existing models involve solving two- or three-dimensional mixed boundary value problems. As such, they are usually analytically intractable and have to be solved numerically instead. A numerical solution is, however, infeasible in real time, hence such models are not suitable for feedback control. We present a novel approximation of the boundary value data for which a closed-form analytical solution is feasible; we solve a mixed boundary value problem numerically off-line only once, and based on this solution we approximate the mixed boundary conditions by Dirichlet boundary conditions. This way we get an approximated boundary value problem allowing the application of the analytical framework of Green's functions. Thus obtained closed-form analytical solution is amenable to real-time use and closely matches the numerical solution of the original exact problem.

description: Two different alloy series (Cu-X, Ni-X) have been selected to investigate the effects of solutes on the saturation grain size, the thermal stability and mechanical properties after high pressure torsion. The results of the Cu-X series indicate that the saturation grain size does not correlate with the stacking fault energy but shows good agreement with solid solution hardening according to the Labusch model. This correlation does not only hold for binaries, but also for chemically complex high entropy alloys (Ni-X) in the form of (CrMnFeCo)xNi1-x, where the Varvenne model is used to describe solid solution hardening. The alloy series exhibit a grain size in the range of 50 – 425 nm after high pressure torsion and the solutes increase the strength as well as the thermal stability of the alloys after annealing. The nanostructured alloys exhibit an enhanced strain rate sensitivity exponent, as determined from nanoindentation strain rate jump and constant contact pressure creep testing, whereas an enhanced rate sensitivity is found at low strain rates. The relatively lower rate sensitivity of the alloys as well as their higher thermal stability indicate, that defect storage and annihilation is strongly influenced by a complex interaction of solutes, dislocations and grain boundaries.

description: We present the detection of 89 low surface brightness (LSB), and thus low stellar density galaxy candidates in the Perseus cluster core, of the kind named "ultra-diffuse galaxies", with mean effective V-band surface brightnesses 24.8-27.1 mag arcsec$^{-2}$, total V-band magnitudes -11.8 to -15.5 mag, and half-light radii 0.7-4.1 kpc. The candidates have been identified in a deep mosaic covering 0.3 square degrees, based on wide-field imaging data obtained with the William Herschel Telescope. We find that the LSB galaxy population is depleted in the cluster centre and only very few LSB candidates have half-light radii larger than 3 kpc. This appears consistent with an estimate of their tidal radius, which does not reach beyond the stellar extent even if we assume a high dark matter content (M/L=100). In fact, three of our candidates seem to be associated with tidal streams, which points to their current disruption. Given that published data on faint LSB candidates in the Coma cluster - with its comparable central density to Perseus - show the same dearth of large objects in the core region, we conclude that these cannot survive the strong tides in the centres of massive clusters.

description: The energy in turbulent flow can be amplified by compression, when the compression occurs on a timescale shorter than the turbulent dissipation time. This mechanism may play a part in sustaining turbulence in various astrophysical systems, including molecular clouds. The amount of turbulent amplification depends on the net effect of the compressive forcing and turbulent dissipation. By giving an argument for a bound on this dissipation, we give a lower bound for the scaling of the turbulent velocity with compression ratio in compressed turbulence. That is, turbulence undergoing compression will be enhanced at least as much as the bound given here, subject to a set of caveats that will be outlined. Used as a validation check, this lower bound suggests that some simulations and models of compressing astrophysical turbulence are too dissipative. The technique used highlights the relationship between compressed turbulence and decaying turbulence.

3FHL: The Third Catalog of Hard Fermi-LAT Sources

description: We present a catalog of sources detected above 10 GeV by the Fermi Large Area Telescope (LAT) in the first 7 years of data using the Pass 8 event-level analysis. This is the Third Catalog of Hard Fermi-LAT Sources (3FHL), containing 1556 objects characterized in the 10 GeV - 2 TeV energy range. The sensitivity and angular resolution are improved by factors of 3 and 2 relative to the previous LAT catalog at the same energies (1FHL). The vast majority of detected sources (79%) are associated with extragalactic counterparts at other wavelengths, including 16 sources located at very high redshift ($z>2$). Eight percent of the sources have Galactic counterparts and 13% are unassociated (or associated with a source of unknown nature). The high-latitude sky and the Galactic plane are observed with a flux sensitivity of 4.4 to 9.5$\times 10^{-11}$ ph cm$^{-2}$ s$^{-1}$, respectively (this is approximately 0.5% and 1% of the Crab Nebula flux above 10 GeV). The catalog includes 214 new $γ$-ray sources. The substantial increase in the number of photons (more than 4 times relative to 1FHL and 10 times to 2FHL) also allows us to measure significant spectral curvature for 32 sources and find flux variability for 163 of them. Furthermore, we estimate that for the same flux limit of $10^{-12}$ erg cm$^{-2}$ s$^{-1}$, the energy range above 10 GeV has twice as many sources as above 50 GeV, highlighting the importance, for future Cherenkov telescopes, of lowering the energy threshold as much as possible.

description: This map poster shows a detailed view of the lake floor bathymetry In Lake Tarawera at a scale of 1:19,000. There are also three smaller maps detailing free air gravity, total magnetic intensity and conductive heat-flow over the lake. The main map shows lake floor features and other subtleties that likely have not been seen for centuries. This includes prominent ridges that strike into the lake from the west and southwest and the extension of lava flows from Mt. Tarawera in the southeast and the large lava domes in the north into the lake. The centre of the lake is largely flat while pockmarks locally dot the margins of the lake, representing gas discharge. This 642 mm by 841 mm sized map is the third in the Rotorua Lakes Map Series. (The authors)

description: Semantic segmentation is a machine learning task that is seeing increased utilization in multiples fields, from medical imagery, to land demarcation, and autonomous vehicles. Semantic segmentation performs the pixel-wise classification of images, creating a new, segmented representation of the input that can be useful for detected various terrain and objects within and image. Recently, convolutional neural networks have been heavily utilized when creating neural networks tackling the semantic segmentation task. This is particularly true in the field of autonomous driving systems. The requirements of automated driver assistance systems (ADAS) drive semantic segmentation models targeted for deployment on ADAS to be lightweight while maintaining accuracy. A commonly used method to increase accuracy in the autonomous vehicle field is to fuse multiple sensory modalities. This research focuses on leveraging the fusion of long wave infrared (LWIR) imagery with visual spectrum imagery to fill in the inherent performance gaps when using visual imagery alone. This comes with a host of benefits, such as increase performance in various lighting conditions and adverse environmental conditions. Utilizing this fusion technique is an effective method of increasing the accuracy of a semantic segmentation model. Being a lightweight architecture is key for successful deployment on ADAS, as these systems often have resource constraints and need to operate in real-time. Multi-Spectral Fusion Network (MFNet) [ 1 ] accomplishes these parameters by leveraging a sensory fusion approach, and as such was selected as the baseline architecture for this research. Many improvements were made upon the baseline architecture by leveraging a variety of techniques. Such improvements include the proposal of a novel loss function categorical cross-entropy dice loss, introduction of squeeze and excitation (SE) blocks, addition of pyramid pooling, a new fusion technique, and drop input data augmentation. These improvements culminated in the creation of the Fast Thermal Fusion Network (FTFNet). Further improvements were made by introducing depthwise separable convolutional layers leading to lightweight FTFNet variants, FTFNet Lite 1 & 2.

description: We perform controlled N-body simulations of disc galaxies growing within live dark matter (DM) haloes to present-day galaxies that contain both thin and thick discs. We consider two types of models: a) thick-disc initial conditions to which stars on near-circular orbits are continuously added over ~10 Gyr and b) models in which the birth velocity dispersion of stars decreases continuously over the same time-scale. We show that both schemes produce double-exponential vertical profiles similar to that of the Milky Way (MW). We indicate how the spatial age structure of galaxies can be used to discriminate between scenarios. We show that the presence of a thick disc significantly alters and delays bar formation and thus makes possible models with a realistic bar and a high baryon-to-DM mass ratio in the central regions, as required by microlensing constraints. We examine how the radial mass distribution in stars and DM is affected by disc growth and non-axisymmetries. We discuss how bar buckling shapes the vertical age distribution of thin- and thick-disc stars in the bar region. The extent to which the combination of observationally motivated inside-out growth histories and cosmologically motivated dark halo properties leads to the spontaneous formation of non-axisymmetries that steer the models towards present-day MW-like galaxies is noteworthy.

Evidential Support and Contraposition

description: The concept of an evidential conditional If A then C that can be defined by the conjunction of A>C and ¬C>¬A, where > is a conditional of the kind introduced by Stalnaker and Lewis, has recently been studied in a series of papers by Vincenzo Crupi and Andrea Iacona. In this paper I argue that Crupi and Iacona’s central idea that contraposition captures the idea of evidential support cannot be maintained. I give examples showing that contraposition is neither necessary nor sufficient for a conditional’s antecedent supporting its consequent. Crupi and Iacona’s alternative account of evidential conditionals that is based on a probabilistic measure of evidential support cannot add to the credentials of their modal account, because both the theoretical role of contraposition and the resulting logic are different in this account.

description: This thesis aims to design and develop the spatial adaptation approach through spatial transformers to improve the accuracy of human keypoint recognition models. We have studied different model types and design choices to gain an accuracy increase over models without spatial transformers and analyzed how spatial transformers increase the accuracy of predictions. A neural network called Widenet has been leveraged as a specialized network for providing the parameters for the spatial transformer. Further, we have evaluated methods to reduce the model parameters, as well as the strategy to enhance the learning supervision for further improving the performance of the model. Our experiments and results have shown that the proposed deep learning framework can effectively detect the human key points, compared with the baseline methods. Also, we have reduced the model size without significantly impacting the performance, and the enhanced supervision has improved the performance. This study is expected to greatly advance the deep learning of human key points and movement dynamics.

EXAMINING RELATIONSHIPS AMONG DEPRESSION TREATMENT, BRAIN-DERIVED NEUROTROPHIC FACTOR (BDNF), AND DEPRESSIVE SYMPTOM CLUSTERS IN PRIMARY CARE PATIENTS WITH DEPRESSION
Creators: name: Crawford, Christopher Andrew
Publisher: name: Purdue University Graduate School

description: Depression is a heterogeneous mental health condition, varying in presentation across individuals. A candidate etiology that may help account for this heterogeneity is the neurotrophin hypothesis of depression, which proposes that stress downregulates brain-derived neurotrophic factor (BDNF) expression, leading to aberrant neurogenesis and depression. This etiology may manifest in a distinct symptom profile that may be reflected in depressive symptoms or symptom clusters. The effect of psychological interventions on BDNF is not known. Additionally, it is not known if BDNF levels mediate intervention effects on depressive symptom clusters. Using data from the eIMPACT trial (NCT02458690, supported by R01 HL122245), I examined baseline associations of BDNF with depressive symptoms and depressive symptom clusters. Also, I examined if the modernized collaborative care intervention for depression (internet CBT, telephonic CBT, and select antidepressant medications) affected BDNF and if changes in BDNF mediated intervention effects on cognitive/affective and somatic depressive symptom clusters. 216 participants (primary care patients with depression and elevated cardiovascular disease risk ≥50 years from a safety net healthcare system) were randomized to 12 months of the eIMPACT intervention (n=107) or usual primary care for depression (primary care providers supported by embedded behavioral health clinicians and affiliated psychiatrists; n=109). Plasma BDNF was measured with commercial ELISA kits. Depressive symptoms were assessed by the PHQ-9 (M=15.1, SD=5.0) from which cognitive/affective and somatic subscale scores were computed. No significant baseline associations were observed between BDNF and individual depressive symptoms or depressive symptom clusters. The intervention did not improve BDNF over 12 months. Similarly, 12-month changes in BDNF were not associated with 12-month changes in PHQ-9 cognitive/affective or somatic subscale scores. However, the intervention significantly improved PHQ-9 cognitive/affective and somatic subscale scores over 12 months. 12-month changes in BDNF did not mediate the effect of the intervention on 12-month changes in the PHQ-9 subscale scores. These findings suggest that modernized collaborative care for depression does not improve BDNF. Modernized collaborative care does yield improvements in both cognitive/affective and somatic depressive symptom clusters, albeit not via changes in BDNF.

description: Chiral Spin Liquids (CSL) based on spin-1/2 fermionic Projected Entangled Pair States (fPEPS) are considered on the square lattice. First, fPEPS approximants of Gutzwiller-projected Chern insulators (GPCI) are investigated by Variational Monte Carlo (VMC) techniques on finite size tori. We show that such fPEPS of finite bond dimension can correctly capture the topological properties of the chiral spin liquid, as the exact GPCI, with the correct topological ground state degeneracy on the torus. Further, more general fPEPS are considered and optimized (on the infinite plane) to describe the CSL phase of a chiral frustrated Heisenberg antiferromagnet. The chiral modes are computed on the edge of a semi-infinite cylinder (of finite circumference) and shown to follow the predictions from Conformal Field Theory. In contrast to their bosonic analogs the (optimized) fPEPS do not suffer from the replication of the chiral edge mode in the odd topological sector.

description: In low-collisionality scenarios exhibiting mitigation of edge localized modes (ELMs), stable ideal kink modes at the edge are excited by externally applied magnetic perturbation (MP)-fields. In ASDEX Upgrade these modes can cause three-dimensional (3D) boundary displacements up to the centimeter range. These displacements have been measured using toroidally localized high resolution diagnostics and rigidly rotating n = 2 MP-fields with various applied poloidal mode spectra. These measurements are compared to non-linear 3D ideal magnetohydrodynamics (MHD) equilibria calculated by VMEC. Comprehensive comparisons have been conducted, which consider for instance plasma movements due to the position control system, attenuation due to internal conductors and changes in the edge pressure profiles. VMEC accurately reproduces the amplitude of the displacement and its dependencies on the applied poloidal mode spectra. Quantitative agreement is found around the low field side (LFS) midplane. The response at the plasma top is qualitatively compared. The measured and predicted displacements at the plasma top maximize when the applied spectra is optimized for ELM-mitigation. The predictions from the vacuum modeling generally fails to describe the displacement at the LFS midplane as well as at the plasma top. When the applied mode spectra is set to maximize the displacement, VMEC and the measurements clearly surpass the predictions from the vacuum modeling by a factor of four. Minor disagreements between VMEC and the measurements are discussed. This study underlines the importance of the stable ideal kink modes at the edge for the 3D boundary displacement in scenarios relevant for ELM-mitigation.

description: Excerpts from the Introduction: Europe and the USSR produce and consume a large share of the world's food and fiber. Assessment of the agricultural and food situation in these areas is basic to a knowledge of world production, consumption, and trade in food and fibers. The indices presented in this publication are a part of the continuing effort of the Economic Research Service (ERS) to assess the world agricultural situation. The country indices are calculated by Laspeyres' base-weighted aggregate formula. The weights used in Eastern Europe and the Soviet Union are estimates of the 1961-65 average price received by farmers in Western Europe, and for West European countries they are the average base period prices received by farmers in each of the individual countries, expressed in U.S. dollars per metric ton. Regional indices are computed from sums of country aggregates. Only those agricultural products of considerable significance in the respective countries are included. Production data are listed under the year in which the bulk of the harvest occurred.

description: The XChronos Manifesto presents a new vision of time, grounded in idealist philosophy, the Copernican paradigm, and the sensitive experience of cosmic motion. The work proposes a profound redefinition of what we understand as “time,” replacing the linear notion with a lived, spatial, and ontological perception. XChronos is not an ordinary clock — it is a mirror of consciousness in motion, an interactive artwork that reveals the self in continuous displacement alongside Gaia, Venus, and Mars. This document serves as a philosophical and conceptual foundation for educational, technological, and artistic projects related to time, reality, and consciousness.
CRITICAL ZONE CALCULATION FOR AUTOMATED VEHICLES USING MODEL PREDICTIVE CONTROL

Year: 2023
Subjects: Electrical machines and drives

description: This thesis studies critical zones of automated vehicles. The goal is for the automated vehicle to complete a car-following or lane change maneuver without collision. For instance, the automated vehicle should be able to indicate its interest in changing lanes and plan how the maneuver will occur by using model predictive control theory, in addition to the autonomous vehicle toolbox in Matlab. A test bench (that includes a scenario creator, motion logic and planner, sensors, and radars) is created and used to calculate the parameters of a critical zone. After a trajectory has been planned, the automated vehicle then attempts the car following or lane change while constantly ensuring its safety to continue on this path. If at any point, the lead vehicle brakes or a trailing vehicle accelerates, the automated vehicle makes the decision to either brake, accelerate, or abandon the lane change.

Τα αποτελέσματα παρουσιάστηκαν σε πίνακες και διαγράμματα. Επιπλέον έγινε έλεγχος του x2 και ANOVA. Σύμφωνα με τα αποτελέσματα οι εκπαιδευτικοί επιμορφώνονται περισσότερο μετά το διορισμό τους. Στόχος του είναι να αποκτήσουν τα απαραίτητα γνωστικά και τυπικά εφόδια που θα τους βοηθήσουν στο έργο τους αλλά και στην επαγγελματική τους ανάπτυξη. Γι’ αυτό επιλέγουν ενότητες ανάλογες με τα προβλήματα που αντιμετωπίζουν. Επίσης, προτιμούν να επιμορφώνονται κατά τις εργάσιμες ημέρες και ώρες λόγω των πολλών επαγγελματικών και προσωπικών τους υποχρεώσεων.

description: We combine $Spitzer$ and ground-based KMTNet microlensing observations to identify and precisely measure an Earth-mass ($1.43^{+0.45}_{-0.32} M_\oplus$) planet OGLE-2016-BLG-1195Lb at $1.16^{+0.16}_{-0.13}$ AU orbiting a $0.078^{+0.016}_{-0.012} M_\odot$ ultracool dwarf. This is the lowest-mass microlensing planet to date. At $3.91^{+0.42}_{-0.46}$ kpc, it is the third consecutive case among the $Spitzer$ "Galactic distribution" planets toward the Galactic bulge that lies in the Galactic disk as opposed to the bulge itself, hinting at a skewed distribution of planets. Together with previous microlensing discoveries, the seven Earth-size planets orbiting the ultracool dwarf TRAPPIST-1, and the detection of disks around young brown dwarfs, OGLE-2016-BLG-1195Lb suggests that such planets might be common around ultracool dwarfs. It therefore sheds light on the formation of both ultracool dwarfs and planetary systems at the limit of low-mass protoplanetary disks.

The triple Higgs coupling: A new probe of low-scale seesaw models
Creators: name: Baglio, Julien

Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The measure of the triple Higgs coupling is one of the major goals of the high-luminosity run of the CERN Large Hadron Collider (HL-LHC) as well as the future colliders, either leptonic such as the International Linear Collider (ILC) or hadronic such as the 100 TeV Future Circular Collider in hadron-hadron mode (FCC-hh). We have recently proposed this observable as a test of neutrino mass generating mechanisms in a regime where heavy sterile neutrino masses are hard to be probed otherwise. We present in this article a study of the one-loop corrected triple Higgs coupling in the inverse seesaw model, taking into account all relevant constraints on the model. This is the first study of the impact on the triple Higgs coupling of heavy neutrinos in a realistic, renormalizable neutrino mass model. We obtain deviations from the Standard Model as large as to $\sim +30\%$ that are at the current limit of the HL-LHC sensitivity, but would be clearly visible at the ILC or at the FCC-hh.

description: XChronos is not just a website. It is an interactive artwork, a Copernican clock, and a philosophical mirror. Rooted in Idealism, cosmic education, and post-materialist thinking, it redefines time not as something that passes, but as something we move through. By measuring time in orbital miles — the actual distance we travel with Earth, Venus, and Mars — XChronos offers a poetic, scientific, and experiential alternative to the industrial clock. It is a living interface where technology serves consciousness, and every user becomes a traveler. This document presents the vision, manifesto, and foundational principles of the XChronos project.
Precise upper deviation estimates for the maximum of a branching random walk

Publisher: name: arXiv
Year: 2024
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: We consider the precise upper large deviations estimates for the maximal displacement of a branching random walk. In addition, we obtain a description of the extremal process of the branching random walk conditioned on this large deviations event. This introduces a family of point measure playing a role similar to the decoration measures introduced in [9] for branching Brownian motion.

Optimal shortcut approach based on an easily obtained intermediate Hamiltonian

description: We present a general approach to speed up the adiabatic process without adding the traditional counterdiabatic driving (CD) Hamiltonian. The strategy is to design an easy-to-get intermediate Hamiltonian to connect the original Hamiltonian and final transitionless Hamiltonian. With final transitionless Hamiltonian, the same target can be achieved as in the adiabatic process governed by the original Hamiltonian, but in a shorter time. We apply the present approach to a three-level system, and the result shows that the final transitionless Hamiltonian usually has the same structure as the original Hamiltonian but with different time-dependent coefficients, allowing speedup to be achieved in a much easier way compared to previous methods.

First Law of Compact Binary Mechanics with Gravitational-Wave Tails

description: We derive the first law of binary point-particle mechanics for generic bound (i.e. eccentric) orbits at the fourth post-Newtonian (4PN) order, accounting for the non-locality in time of the dynamics due to the occurence of a gravitational-wave tail effect at that order. Using this first law, we show how the periastron advance of the binary system can be related to the averaged redshift of one of the two bodies for a slightly non-circular orbit, in the limit where the eccentricity vanishes. Combining this expression with existing analytical self-force results for the averaged redshift, we recover the known 4PN expression for the circular-orbit periastron advance, to linear order in the mass ratio.

description: O Manifesto XChronos apresenta uma nova visão do tempo, baseada na filosofia idealista, no paradigma copernicano e na experiência sensível do movimento cósmico. A obra propõe uma ressignificação profunda do que entendemos por "tempo", substituindo a noção linear por uma percepção vivencial, espacial e ontológica. O XChronos não é um relógio comum — é um espelho da consciência em fluxo, uma arte interativa que revela o ser em deslocamento contínuo com Gaia, Vênus e Marte. Este documento serve como base filosófica e conceitual para projetos educacionais, tecnológicos e artísticos relacionados ao tempo, à realidade e à consciência.
Quantum Zeno effects from measurement controlled qubit-bath interactions

description: The Zeno and anti-Zeno effects are features of measurement-driven quantum evolution where frequent measurement inhibits or accelerates the decay of a quantum state. Either type of evolution can emerge depending on the system-environment interaction and measurement method. In this experiment, we use a superconducting qubit to map out both types of Zeno effect in the presence of structured noise baths and variable measurement rates. We observe both the suppression and acceleration of qubit decay as repeated measurements are used to modulate the qubit spectrum causing the qubit to sample different portions of the bath. We compare the Zeno effects arising from dispersive energy measurements and purely-dephasing `quasi'-measurements, showing energy measurements are not necessary to accelerate or suppress the decay process.

description: Η έρευνα για το σχολικό κλίμα και τις σχέσεις εκπαιδευτικών-μαθητών δεν είναι ένα νέο πεδίο έρευνας. Οι επιστήμονες μελετούν το σχολικό κλίμα για πάνω από 100 χρόνια, προσπαθώντας να ορίσουν, να κατανοήσουν και να προσδιορίσουν τον αντίκτυπό του στις πολλές πτυχές της σχολικής ζωής. Η προσέγγιση των ερευνητών για το σχολικό κλίμα βασίζεται στον ορισμό που συνδέει το σχολικό κλίμα με την ποιότητα και το χαρακτήρα της σχολικής ζωής και περιλαμβάνει κανόνες, αξίες και προσδοκίες που υποστηρίζουν τους ανθρώπους να αισθάνονται κοινωνικά, συναισθηματικά και σωματικά ασφαλείς. Σκοπός της παρούσας διπλωματικής εργασίας είναι να διερευνήσει το κατά πόσο το στιλ ηγεσίας που επιλέγουν να ασκήσουν οι διευθυντές πρωτοβάθμιας και δευτεροβάθμιας εκπαίδευσης στην Ελλάδα επηρεάζει τις σχέσεις μεταξύ εκπαιδευτικών και μαθητών.
