description: Αντικείμενο μελέτης της διπλωματικής εργασίας αποτελεί ο θεσμός της επικαρπίας. Συγκεκριμένα, για λόγους συστηματικής έρευνας η παρούσα μελέτη χωρίζεται σε δύο κεφάλαια. Το πρώτο περιλαμβάνει την μορφολογία της επικαρπίας, ενώ το δεύτερο τη σύστασή της. Ειδικότερα, στο πρώτο κεφάλαιο επιχειρείται να διευκριστεί η έννοια της επικαρπίας, η ανάλυση των ιδιαίτερων γνωρισμάτων της που την καθορίζουν και την διαφοροποιούν από τα υπόλοιπα δικαιώματα, καθώς επίσης και τα ιδιαίτερα χαρακτηριστικά της. Στο πρώτο κεφάλαιο δηλαδή επιχειρείται μια πλήρης ερμηνευτική προσέγγιση έτσι ώστε να γίνει αντιληπτή η θέση της επικαρπίας στο χώρο του δικαίου και ειδικότερα στο σύστημα του εμπραγμάτου δικαίου. Στο δεύτερο κεφάλαιο αναλύονται οι τρόποι σύστασης της επικαρπίας και τα επιμέρους ζητήματα που ανακύπτουν.
description: Subject of the study in this master thesis is the legal status of usufruct. In particular, the study is divided in two sections for the sake of better systematic research. The first section deals with the morphology of the usufruct, whereas the second with the constitution of usufruct. In the first section it is attempted to clarify the term of usufruct, to analyse those specific characteristics that define and differentiate usufruct from the rest of property rights. This means that a fully interpretational approach is pursued in order to comprehend the importance of usufruct both in the field of general law as well as in the field of specific law of property. In the second section an analysis of the ways of constituting usufruct is presented, along with the legal matters that occur during this process.

description: The double copy suggests that the basis of the dynamics of general relativity is Yang-Mills theory. Motivated by the importance of the relativistic two-body problem, we study the classical dynamics of colour-charged particle scattering from the perspective of amplitudes, rather than equations of motion. We explain how to compute the change of colour, and the radiation of colour, during a classical collision. We apply our formalism at next-to-leading order for the colour change and at leading order for colour radiation.

Rounding up the wanderers: optimizing coronagraphic searches for extrasolar planets
Creators: name: Agol, Eric
Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I derive analytic scalings for coronagraphic imaging searches for extrasolar planets. I compute the efficiency of detecting planets about any given star, and from this compute dimensionless distribution functions for the detected planets as a function of planet-star distance and distance to the host stars. I find the following for blind planet surveys: (1) the optimum wavelength is between 4000-5000 Angstroms for Earth-like planets and 4200-5800 Angstroms for Jovian planets; (2) between 21-32% of the number of planets per decade of radius can be detected with an optimized survey; (3) target stars should be ranked from greatest to least by their luminosity divided by distance to the sixth or eighth power, depending on the dominant source of noise for the survey; (4) surveys targeting all main sequence stars will detect ~3 times as many planets as surveys only targeting G-type stars; and (5) stellar populations with different metallicities should have exposure times that vary with the cube of the metallicity. I apply these results to the current suite of proposed coronagraphic satellite telescopes, of which TPF-C is the most powerful, but a much smaller telescope, TOPS, may have a significant chance of detecting Earth-sized planets due to its small inner working angle and high throughput. The most significant uncertainty in these results is the noise contribution of Exo-zodiacal light. These results can be applied to designing coronagraphs, comparing proposed telescope designs, optimizing the observing strategies, determining the properties of detected planet populations, and selecting target stars.

description: Heavy-flavour hadrons, containing open or hidden charm and beauty flavours, are considered as hard probes of the quark-gluon plasma (QGP), which is a hot and dense phase state of quantum chromodynamics (QCD) matter. Production of heavy flavours involves large momentum transfer processes during collisions. Heavy quarks are expected to be produced in the initial stage of collisions and therefore prior to the formation of the QGP in heavy-ion collisions. Consequently, heavy quarks travel through and interact with the QGP. Hence, measuring both open and hidden heavy-flavour production in large systems provides information on the QGP properties and heavy quark hadronisation. Heavy-flavour production is measured in small and large systems with ALICE in order to test (perturbative) QCD and study the effects induced by the medium. In this contribution, recent ALICE results on heavy-flavour production in pp, p-Pb and Pb-Pb collisions are reported.

description: The nematode Caenorhabditis elegans responds to an impressive range of chemical, mechanical and thermal stimuli and is extensively used to investigate the molecular mechanisms that mediate chemosensation, mechanotransduction and thermosensation. The main behavioral output of these responses is manifested as alterations in animal locomotion. Monitoring and examination of such alterations requires tools to capture and quantify features of nematode movement. In this paper, we introduce Nemo (nematode movement), a computationally efficient and robust two-dimensional object tracking algorithm for automated detection and analysis of C. elegans locomotion. This algorithm enables precise measurement and feature extraction of nematode movement components. In addition, we develop a Graphical User Interface designed to facilitate processing and interpretation of movement data. While, in this study, we focus on the simple sinusoidal locomotion of C. elegans, our approach can be readily adapted to handle complicated locomotory behaviour patterns by including additional movement characteristics and parameters subject to quantification. Our software tool offers the capacity to extract, analyze and measure nematode locomotion features by processing simple video files. By allowing precise and quantitative assessment of behavioral traits, this tool will assist the genetic dissection and elucidation of the molecular mechanisms underlying specific behavioral responses.

description: The first results of a new survey are reported, which explores the 2nd data release of the ESA-Gaia mission, in order to search for stellar companions of (Community) TESS Objects of Interest and to characterize their properties. In total, 193 binary and 15 hierarchical triple star systems are presented, detected among 1391 target stars, which are located at distances closer than about 500pc around the Sun. The companions and the targets are equidistant and share a common proper motion, as it is expected for gravitationally bound stellar systems, proven with their accurate Gaia astrometry. The companions exhibit masses in the range between about 0.08$M_\odot$ and 3$M_\odot$ and are most frequently found in the mass range between 0.13 and 0.6$M_{\odot}$. The companions are separated from the targets by about 40 up to 9900au, and their frequency continually decreases with increasing separation. While most of the detected companions are late K to mid M dwarfs, also 5 white dwarf companions were identified in this survey, whose true nature is revealed by their photometric properties.

In particular we investigate the coupling constant $g_{D_{sJ}DK}$. We found that the $g_{D_{sJ}DK}$ obtained in this four-quark scenario is smaller than the coupling constant obtained when $D_{sJ}^{+}(2317)$ is considered as a conventional $c\bar{s}$ state.

Vor dem Hintergrund der Zuschreibung einer mythologisierenden Funktion von Literatur schafft Grass in seinem 1995 erschienenen Roman Ein weites Feld einen anderen Typus einer mythischen Verehrung: Unter Weiterentwicklung des von Thomas Mann entworfenen Postulats eines mythischen In-Spuren-Gehens gelingt es ihm, in der Gestalt des Fonty Leben und Werk Theodor Fontanes gleichermaßen zu spiegeln und den öffentlichen Gedächtniskulturen gegenüberzustellen.

description: Grain growth has a definitive impact on the quality of transparent sintered materials in areas such as ballistics, biomaterials, jewelry, etc. Controlling the sintering trajectory at the precise moment of final stage sintering is one of the main sintering challenges for obtaining highperformance, fully-dense nano-ceramics. However, the final stage of sintering involves a very complex coupling between the rate of porosity elimination/grain growth and transition mechanisms. This complexity makes predicting the sintering trajectory very difficult, and most transparent material production escapes this problem by using expensive high-pressure methods such as hot isostatic pressing (HIP). In the quest for a pressureless transparent material process, this paper addresses the challenge of predicting grain growth in the transition domain from the grain growth onset (in a high porosity region) to full density for MgAl 2 O 4 spinel. We present a comprehensive modeling approach linking theoretical models such as Zhao \& Harmer's and Olevsky's equations to accurately predict the complex grain growth transition region of final stage sintering. This modeling approach opens up the possibility for numerical exploration of microstructure development via underlying kinetics experimental identification.

description: Small perturbations in the dielectric environment around a high quality whispering gallery mode resonator usually lead to a frequency shift of the resonator modes directly proportional to the polarizability of the perturbation. Here, we report experimental observations of strong frequency shifts that can be opposite and even exceed the contribution of the perturbations' polarizability. The mode frequencies of a lithium niobate whispering gallery mode resonator are shifted using substrates of refractive indices ranging from 1.50 to 4.22. Both blue- and red-shifts are observed, as well as an increase in mode linewidth, when substrates are moved into the evanescent field of the whispering gallery mode. We compare the experimental results to a theoretical model by Foreman et al. and provide an additional intuitive explanation based on the Goos-Hänchen shift for the optical domain.

Στην έρευνα συμμετείχαν εθελοντικά 36 γυναίκες, από τις οποίες εκτιμήθηκε το 1 RM στο ημικάθισμα και στις πιέσεις πάγκου ενώ έπειτα ακολούθησαν πρόγραμμα ενδυνάμωσης σε πλατφόρμα δόνησης διάρκειας 6 εβδομάδων με συχνότητα προπόνησης 2 φορές/εβδομάδα. Οι συμμετέχουσες χωρίστηκαν σε 4 ομάδες με κύρια διαφοροποίηση μεταξύ των ομάδων τη συχνότητα δόνησης. Η πρώτη ομάδα έκανε προπόνηση στα 16 Hz, η δεύτερη στα 19 Hz, ενώ η τρίτη στα 21 Hz. Η τέταρτη ομάδα αποτέλεσε την ομάδα ελέγχου. Μετά το τέλος της παρέμβασης εκτιμήθηκαν ξανά οι νέες τιμές του 1 RM. Τα αποτελέσματα έδειξαν αύξηση στη δύναμη των κάτω άκρων για τις ομάδες των 16 και 19 Hz, ενώ η ομάδα των 21 Hz αν και παρουσίασε αύξηση στη δύναμη, η αύξηση αυτή δεν ήταν στατιστικά σημαντική. Η δύναμη των άνω άκρων μεταβλήθηκε επίσης θετικά για τις τρεις ομάδες, αλλά δεν ήταν στατιστικά σημαντική. Τα ποσοστά της δύναμης για τα άνω άκρα δεν αυξήθηκαν σημαντικά σε σχέση με την ομάδα ελέγχου, πιθανά λόγω αδυναμίας εξομοίωσης των ασκήσεων αξιολόγησης των άνω άκρων στην πλατφόρμα δόνησης. Συμπερασματικά, η προπόνηση δόνησης σε αμφίπλευρο επίπεδο αύξησε σημαντικά τη δύναμη των κάτω άκρων σε ενήλικες γυναίκες, ενώ δεν επηρέασε κατά πολύ τη δύναμη στα άνω άκρα.
description: The purpose of the present study was to determine the effects of vibration training on a Galileo device on the alterations of strength in a group of adult women. Thirty six females that volunteered to participate in the current study performed two maximal tests on squat and bench press on a Smith Machine in order to evaluate their 1 RM. Next, the participants were trained on a vibration device for six weeks. The main difference between the groups was that they were trained in different vibration frequencies. The first group was trained on 16 Hz, the second on 19 Hz and the third on 21 Hz. The fourth group was the control group. After the six weeks of vibration training, 1 RM evaluated again. The results showed a significant increase of strength for the squat for the groups of 16 and 19 Hz, while the 21 Hz group did not change significantly. The strength for the bench press did not change significantly in any one of the training groups. This finding may resulted because of not appropriate simulation of the test exercise on the vibration device. In conclusion, vibration training on Galileo device resulted in increase of squat strength, while did not change significantly the values of the bench press.

description: The GRAVITY instrument on the ESO VLTI pioneers the field of high-precision near-infrared interferometry by providing astrometry at the $10 - 100\,μ$as level. Measurements at such high precision crucially depend on the control of systematic effects. Here, we investigate how aberrations introduced by small optical imperfections along the path from the telescope to the detector affect the astrometry. We develop an analytical model that describes the impact of such aberrations on the measurement of complex visibilities. Our formalism accounts for pupil-plane and focal-plane aberrations, as well as for the interplay between static and turbulent aberrations, and successfully reproduces calibration measurements of a binary star. The Galactic Center observations with GRAVITY in 2017 and 2018, when both Sgr A* and the star S2 were targeted in a single fiber pointing, are affected by these aberrations at a level of less than 0.5 mas. Removal of these effects brings the measurement in harmony with the dual beam observations of 2019 and 2020, which are not affected by these aberrations. This also resolves the small systematic discrepancies between the derived distance $R_0$ to the Galactic Center reported previously.
Recent developments in premetric classical electrodynamics

description: Classical electrodynamics can be based on the conservation laws of electric charge and magnetic flux. Both laws are independent of the metric and the linear connection of spacetime. Within the framework of such a premetric electrodynamics -- provided a local and linear constitutive law of the vacuum is added -- the propagation of electromagnetic waves in the geometric-optics limit can be studied. The wave vectors of the wave fronts obey a quartic extended Fresnel equation. If one forbids birefringence in vacuum, the light cone emerges and Maxwell-Lorentz vacuum electrodynamics can be recovered. If minimal coupling of electrodynamics to gravity is assumed, then only the gravitational potential, i.e., the metric of spacetime, emerges in the constitutive law. We discuss recent results within this general framework.

description: We use path integrals to calculate perturbative corrections to the correlation function of a particle under the action of nonlinear optical tweezers, both in the overdamped and underdamped regimes. In both cases, it is found that to leading order nonlinearities manifest as shifts in the characteristic frequency of the system. The results are compared to numerical simulations. The present calculations enable a direct experimental method to access the nonlinear optical trap parameters by analyzing position data, similarly to standard harmonic tweezers.

description: The dependence of the Josephson Plasma Resonance (JPR) frequency in heavily underdoped Bi2Sr2CaCu2O8+δon temperature and controlled pointlike disorder, introduced by high-energy electron irradiation, is cross-correlated and compared to the behavior of the ab-plane penetration depth. It is found that the zero temperature plasma frequency, representative of the superfluid component of the c-axis spectral weight, decreases proportionally with T_c when the disorder is increased. The temperature dependence of the JPR frequency is the same for all disorder levels, including pristine crystals. The reduction of the c-axis superfluid density as function of disorder is accounted for by pair-breaking induced by impurity scattering in the CuO2 planes, rather than by quantum fluctuations of the superconducting phase. The reduction of the c-axis superfluid density as function of temperature follows a T^{2}--law and is accounted for by quasi-particle hopping through impurity induced interlayer states.

description: The aim of this study was to investigate the relationship between the polymorphisms of mannose binding lectin gene (MBL2) in association with the susceptibility of infections in children with acute lymphoblastic leukemia (ALL). The subjects enrolled in this retrospective study included 30 children with ALL admitted in the Pediatric Oncology-Hematology Unit of AHEPA Hospital during the period 2003-2007. All children received the same chemotherapy regimen protocol BFM 95 and were followed up for the period from the beginning of their chemotherapy treatment till the start of the consolidation therapy. MBL genotype was determined with RFLP-PCR and was correlated to clinical (number of febrile episodes (FEN), duration of fever neutropenia, number of infections) and laboratory (causative agents of bacterial infections) parameters. Pediatric patients with MBL deficiency showed an increased risk of infection, (there was a statistical significant difference in the number of infections p=0,024, the number of FEN episodes p=0,032 and the duration of fever neutropenia p=0,04) compared to children with normal MBL genotype. This study suggests that MBL polymorphisms may be clinical useful to identify pediatric leukemia patients who are at increased risk of bacterial infections during their immunosuppressive condition. Additional prospective studies may be required.

For the first time, the experimentally known instability of microwave sintering is explained coupling the effective medium approximation and finite-element method. We show how the material dielectric permittivity imaginary part which increases with temperature and relative density encourages high hot spot phenomena. It is shown that the sample location has a great impact on the

description: In this paper we review the possible radiation mechanisms for the observed non-thermal emission in clusters of galaxies, with a primary focus on the radio and hard X-ray emission. We show that the difficulty with the non-thermal, non-relativistic Bremsstrahlung model for the hard X-ray emission, first pointed out by Petrosian (2001) using a cold target approximation, is somewhat alleviated when one treats the problem more exactly by including the fact that the background plasma particle energies are on average a factor of 10 below the energy of the non-thermal particles. This increases the lifetime of the non-thermal particles, and as a result decreases the extreme energy requirement, but at most by a factor of three. We then review the synchrotron and so-called inverse Compton emission by relativistic electrons, which when compared with observations can constrain the value of the magnetic field and energy of relativistic electrons. This model requires a low value of the magnetic field which is far from the equipartition value. We briefly review the possibilities of gamma-ray emission and prospects for GLAST observations. We also present a toy model of the non-thermal electron spectra that are produced by the acceleration mechanisms discussed in an accompanying paper.

description: A first-principles-derived method is used to study the morphology and electric-field-induced evolution of stripe nanodomains in (001) BaTiO3 (BTO) ultrathin films, and to compare them with those in (001) Pb(Zr,Ti)O3 (PZT) ultrathin films. The BaTiO3 systems exhibit 180o periodic stripe domains at null electric field, as in PZT ultrathin films. However, the stripes alternate along [1-10] in BTO systems versus [010] in PZT systems, and no in-plane surface dipoles occur in BTO ultrathin films (unlike in PZT materials). Moreover, the evolution of the 180o stripe domains in the BaTiO3 systems, when applying and increasing an electric field along [001], involves four regions: Region I for which the magnitude of the down dipoles (i.e., those that are antiparallel to the electric field) is reduced, while the domain walls do not move; Region II in which some local down dipoles adjacent to domain walls switch their direction, resulting in zigzagged domain walls - with the overall stripe periodicity being unchanged; Region III in which nanobubbles are created, then contract along [110] and finally collapse; and Region IV which is associated with a single monodomain. Such evolution differs from that of PZT ultrathin films for which neither Region I nor zigzagged domain walls exist, and for which the bubbles contract along [100]. Discussion about such differences is provided.
