description: Space debris is a major threat to the satellite infrastructure. A collision with even small particle, e.g. 1 cm of size, can cause a catastrophic event when the parent body, spacecraft or upper stage, will break up into hundreds of trackable fragments. Space debris research helps to discover, monitor and characterize these objects, identify their origin and support their active removal. Surveys with optical telescopes aim to discover new objects for cataloguing and to increase the accuracy of space debris population models. The follow-up observations are performed to improve their orbits or to investigate their physical characteristics. We will present the space debris population, its orbital and physical characteristics and we will discuss the role which the optical telescopes play in space debris research. We will also discuss the adopted astronomical techniques like astrometry, photometry and spectroscopy used in the space debris domain.

description: Representing an ensemble of random lasers with an ensemble of random matrices, we compute average number of lasing modes and its fluctuations. The regimes of weak and strong coupling of the passive resonator to environment are considered. In the latter case, contrary to an earlier claim in the literature, we do not find a power-law dependence of the average mode number on the pump strength. For the relative fluctuations, however, a power law can be established. It is shown that, due to the mode competition, the distribution of the number of excited modes over an ensemble of lasers is not binomial.

On the Origin of GW190521-like events from repeated black hole mergers in star clusters

description: LIGO and Virgo have reported the detection of GW190521, from the merger of a binary black hole (BBH) with a total mass around $150$ M$_\odot$. While current stellar models limit the mass of any black hole (BH) remnant to about $40 - 50$ M$_\odot$, more massive BHs can be produced dynamically through repeated mergers in the core of a dense star cluster. The process is limited by the recoil kick (due to anisotropic emission of gravitational radiation) imparted to merger remnants, which can escape the parent cluster, thereby terminating growth. We study the role of the host cluster metallicity and escape speed in the buildup of massive BHs through repeated mergers. Almost independent of host metallicity, we find that a BBH of about $150$ M$_\odot$ could be formed dynamically in any star cluster with escape speed $\gtrsim 200$ km s$^{-1}$, as found in galactic nuclear star clusters as well as the most massive globular clusters and super star clusters. Using an inspiral-only waveform, we compute the detection probability for different primary masses ($\ge 60$ M$_\odot$) as a function of secondary mass and find that the detection probability increases with secondary mass and decreases for larger primary mass and redshift. Future additional detections of massive BBH mergers will be of fundamental importance for understanding the growth of massive BHs through dynamics and the formation of intermediate-mass BHs.

description: We study scalar cosmological perturbations in a braneworld model with a bulk Gauss-Bonnet term. For an anti-de Sitter bulk, the five-dimensional perturbation equations share the same form as in the Randall-Sundrum model, which allows us to obtain metric perturbations in terms of a master variable. We derive the boundary conditions for the master variable from the generalized junction conditions on the brane. We then investigate several limiting cases in which the junction equations are reduced to a feasible level. In the low energy limit, we confirm that the standard result of four-dimensional Einstein gravity is reproduced on large scales, whereas on small scales we find that the perturbation dynamics is described by the four-dimensional Brans-Dicke theory. In the high energy limit, all the non-local contributions drop off from the junction equations, leaving a closed system of equations on the brane. We show that, for inflation models driven by a scalar field on the brane, the Sasaki-Mukhanov equation holds on the high energy brane in its original four-dimensional form.

Deep MIPS Observations of the IC 348 Nebula: Constraints on the Evolutionary State of Anemic Circumstellar Disks and the Primordial-to-Debris Disk Transition

description: We describe new, deep MIPS photometry and new high signal-to-noise optical spectroscopy of the 2.5 Myr-old IC 348 Nebula. To probe the properties of the IC 348 disk population, we combine these data with previous optical/infrared photometry and spectroscopy to identify stars with gas accretion, to examine their mid-IR colors,and to model their spectral energy distributions. IC 348 contains many sources in different evolutionary states, including protostars and stars surrounded by primordial disks, two kinds of transitional disks, and debris disks. Most disks surrounding eary/intermediate spectral-type stars (> 1.4 Msun at 2.5 Myr) are debris disks; most disks surrounding solar and subsolar-mass stars are primordial disks. At the 1--2 sigma level, more massive stars also have a smaller frequency of gas accretion and smaller mid-IR luminosities than lower-mass stars. These trends are suggestive of a stellar mass-dependent evolution of disks, where most disks around high/intermediate-mass stars shed their primordial disks on rapid, 2.5 Myr timescales. The frequency of MIPS-detected transitional disks is ~ 15--35% for stars plausibly more massive than 0.5 Msun. The relative frequency of transitional disks in IC 348 compared to that for 1 Myr-old Taurus and 5 Myr-old NGC 2362 is consistent with a transition timescale that is a significant fraction of the total primordial disk lifetime.

description: In this essay the author throughout a historical view of the theories about danger that have been accomplished tries to prove that the recent notion of danger is based to the results of present theories that are juristically and sociological established in Germany. The aspect of danger that is social for the ellay is that of the danger provoted to humans and the leggitimate goods either social or individual. The aspect is being analysed thoroughly with the help of the theories developed in Greece that are affectes of the German one. The notion of danger is better defined when it appears to a category of crimes related to that. So iti is explained why danger has a different meaning when it comes to a certain category of crimes as well as the meaning of danger as a technical term of greek penal call.

description: Ice shell dynamics are an important control on the habitability of icy ocean worlds. Here we present a systematic study evaluating the effect of temperature-dependent material properties on these dynamics. We review the published thermal conductivity data for ice, which demonstrates that the most commonly used conductivity model in planetary science represents a lower bound. We propose a new model for thermal conductivity that spans the temperature range relevant to the ice shells of ocean worlds. This increases the thermal conductivity at low temperatures near the surface by about a fifth. We show that such an increase in thermal conductivity near the cold surface can stabilizes the ice shell of Europa. Furthermore, we show that including temperature dependent specific heat capacity decreases the energy stored in the conductive lid which reduces the response timescale of the ice shell to thermal perturbations by approximately a third. This may help to explain surface features such as chaotic terrains that require large additions of energy to the near-surface ice.

We find that the sign of the AMR can be positive or negative, which may depend on the direction of the current with respect to the crystal. At low temperatures, transport measurements and SQUID magnetometry suggest that the magnetisation has a component pointing out of the plane of the film.

Ως δείγμα χρησιμοποιήθηκαν 60 αθλητές, εξίσου αγόρια και κορίτσια με μέσο όρο ηλικίας 13,61 (± 1,48) χρόνια και εμπειρία αγώνων σε τοπικό και/ή περιφερειακό επίπεδο. Η μέθοδος της μελέτης είχε δύο στάδια. Στο πρώτο, οι αθλητές μετρήθηκαν σε δυο παραμέτρους (ακρίβεια, σκορ), σε μια δοκιμασία που κατέγραφε τις επιδόσεις στο forehand και στο backhand. Οι μετρήσεις στα δύο αυτά κτυπήματα, πραγματοποιήθηκαν στη συνέχεια, αρχικά με την παρεμβολή οπτικών και κατόπιν ακουστικών ερεθισμάτων. Μετά την πάροδο μιας εβδομάδας, οι μετρήσεις επαναλήφθηκαν, στο ίδιο δείγμα(έλεγχος αξιοπιστίας). Τα αποτελέσματα έδειξαν, ότι οι τιμές της δεύτερης μέτρησης ήταν σαφώς καλύτερες από εκείνες της πρώτης. Ωστόσο η αξιοπιστία των μετρήσεων κυμάνθηκε σε ικανοποιητικά επίπεδα (r=.83). Επιπλέον, αποδείχθηκε η αρνητική επιρροή των οπτικοακουστικών ερεθισμάτων στην επίδοση των αθλητών, πρωτίστως των οπτικών και δευτερευόντως των ακουστικών ερεθισμάτων. Συμπερασματικά, η παρούσα μελέτη κατέδειξε, ότι οι οπτικοακουστικές ενοχλήσεις επιδρούν αρνητικά στην επίδοση των νεαρών αθλητών αντισφαίρισης ηλικίας 12-15 ετών, οι οποίοι, ως εκ τούτου, πρέπει να προπονούνται έτσι, ώστε να αντιπαρέρχονται αυτές τις ενοχλήσεις επιτυχώς, για να αποδίδουν ιδανικά στον αγώνα.
description: The purpose of the study was to examine the effects of visual and hearing influences on the performance of young tennis players aged between 12 – 15 years old. The sample comprised 60 athletes, 30 males and 30 females respectively with the average age of 13,61 ( + 1,48 ) years and previous competitive experience in local and/or peripheral levels. The method used during the study was completed in two sessions. Firstly, all participants were measured according to two variables (precision, score) while performing a forehand and a backhand drive test where competence was being registered. The measurings during the performance of these two strikes were imitially realized with the insertion of visual and later of hearing stimuli. A week later, the measurings were repeated using the same sample (reliability control). The results showed that the values of the second measuring were clearly better than the values of the first. However, the measuring`s reliability ranges within satisfactory levels (r=.83). Moreover, the negative effects of visual and hearing influences upon the athlete`s performance proved to be mainly visual and secondanly hearing. In conclusion, the present study showed that the visual and hearing influences have negative effects on the performance of young tennis players between 12 – 15 years of age, who should be trained accordingly, so as to overcome successfully those influences and perform their best!

description: The L-dependence of the static potential between Nc quarks arranged in a circle of radius L (a "baryon") immersed in the hot plasma of a gauge theory with Nc colors defines a screening length Ls. We use the AdS/CFT correspondence to compute this screening length for the case of heavy quarks in the plasma of strongly coupled N=4 super Yang-Mills theory moving with velocity v relative to the baryon. We find that in the v -> 1 limit, Ls \propto (1-v^2)^{1/4}/T, and find that corrections to this velocity dependence are small at lower velocities. This result provides evidence for the robustness of the analogous behavior of the screening length defined by the static quark-antiquark pair, which has been computed previously and in QCD is relevant to quarkonium physics in heavy ion collisions. Our results also show that as long as the hot wind is not blowing precisely perpendicular to the plane of the baryon configuration that we analyze, the Nc different quarks are not all affected by the wind velocity to the same degree, with those quarks lying perpendicular to the wind direction screened most effectively.

description: The unprecedented sky coverage and observing cadence of the All-Sky Automated Survey for SuperNovae (ASAS-SN) has resulted in the discovery and continued monitoring of a large sample of Galactic transients. The vast majority of these are accretion-powered dwarf nova outbursts in cataclysmic variable systems, but a small subset are thermonuclear-powered classical novae. Despite improved monitoring of the Galaxy for novae from ASAS-SN and other surveys, the observed Galactic nova rate is still lower than predictions. One way classical novae could be missed is if they are confused with the much larger population of dwarf novae. Here, we examine the properties of 1617 dwarf nova outbursts detected by ASAS-SN and compare them to classical novae. We find that the mean classical nova brightens by ~11 magnitudes during outburst, while the mean dwarf nova brightens by only ~5 magnitudes, with the outburst amplitude distributions overlapping by roughly 15%. For the first time, we show that the amplitude of an outburst and the time it takes to decline by two magnitudes from maximum are positively correlated for dwarf nova outbursts. For classical novae, we find that these quantities are negatively correlated, but only weakly, compared to the strong anti-correlation of these quantities found in some previous work. We show that, even if located at large distances, only a small number of putative dwarf novae could be mis-classified classical novae suggesting that there is minimal confusion between these populations. Future spectroscopic follow-up of these candidates can show whether any are indeed classical novae.

description: Whereas Single Negative (SNG) and Double Negative (DNG) dielectric materials (also known and as metamaterials), are being consisted of a combination of dielectrics with positive permittivity and permeability, it is possible by suitable values of their geometrical and structural characteristics, to behave as structures with negative permittivity or / and permeability. The use of spherical particles with the appropriate diameter, electric permittivity and magnetic permeability, which form a lattice embedded in a dielectric substrate, can lead to a hybrid material with SNG or DNG performance. In this project a composition of SNG and DNG materials has been done using this method. The constructed materials were used to load the WR-90 rectangular waveguide (working area: 8-12 GHz). The study of the frequency response, revealed that with the appropriate design of SNG and DNG loads, they can work as microwave filters with very interesting application characteristics, as flat response in the bandpass or in the bandstop section, very fast reduction of the signal power at the limits of these sections and the ability to control the bandwidth by changing the SNG and DNG load characteristics.

description: We address the hypothesis that High Velocity Clouds correspond to the "missing" dwarf galaxies of the Local Group predicted by cosmological simulations. To this end, we present optical and near-infrared photometry of five additional High Velocity Clouds, one of which produces Lyman series absorption on the sight line towards the Quasar Ton S210, with sufficient resolution and sensitivity to enable the detection of an associated stellar content. We do not detect significant stellar populations intrinsic to any of the five clouds. In combination with the results from our paper I, which had yielded non detections of stellar content in another five cases, we find that there is a 50% chance of getting a null result in ten trials if fewer than 7% of all High Velocity Clouds contain stars. We conclude that the population of High Velocity Clouds is an unlikely repository for the "missing" dwarfs of the Local Group.

description: Asymptotic Giant Branch (AGB) stars are typified by strong dust-driven, molecular outflows. For long, it was believed that the molecular setup of the circumstellar envelope of AGB stars is primarily determined by the atmospheric C/O ratio. However, recent observations of molecules such as HCN, SiO, and SO reveal gas-phase abundances higher than predicted by thermodynamic equilibrium (TE) models. UV-photon initiated dissociation in the outer envelope or non-equilibrium formation by the effect of shocks in the inner envelope may be the origin of the anomolous abundances. We aim at detecting (i.) a group of `parent' molecules (CO, SiO, HCN, CS), predicted by the non-equilibrium study of Cherchneff (2006) to form with almost constant abundances independent of the C/O ratio and the stellar evolutionary stage on the Asymptotic Giant Branch (AGB), and (ii.) few molecules, such as SiS and SO,which are sensitive to the O- or C-rich nature of the star. Several low and high excitation rotational transitions of key molecules are observed at mm and sub-mm wavelengths with JCMT and APEX in four AGB stars: the oxygen-rich Mira WX Psc, the S star W Aql, and the two carbon stars V Cyg and II Lup. A critical density analysis is performed to determine the formation region of the high-excitation molecular lines. We detect the four `parent' molecules in all four objects, implying that, indeed, these chemical species form whatever the stage of evolution on the AGB. High-excitation lines of SiS are also detected in three stars with APEX, whereas SO is only detected in the oxygen-rich star WX Psc. This is the first multi-molecular observational proof that periodically shocked layers above the photosphere of AGB stars show some chemical homogeneity, whatever the photospheric C/O ratio and stage of evolution of the star.

Effects of additives on analyte migration behavior in capillary electrophoresis
Creators: name: Kranack, Andrea R.
Publisher: name: University of British Columbia
Year: 2009

description: The aim of this work is to study the effects of additives on the analyte migration behavior in capillary electrophoresis (CE). The first part of this thesis presents an investigation into the interaction between the analytes and the additives in both the liquid and gas phase. ß-Cyclodextrin (ß-CD) was used as the additive and several nitrophenols were employed as analytes to compare the trends of the binding affinity in the gas and liquid phase. It was demonstrated that the trend of the equilibrium constants (K) in the aqueous phase determined by CE was the same as in the gaseous phase determined by electrospray mass spectrometry. It was also concluded that ammonium ions were bound to (ß-CD in the gas phase. The second part of this thesis presents a quantitative study of ion-pairing interactions in CE. The ion-pairing agents dodecyltrimethylammonium bromide (DTAB) and tetramethylarnmonium bromide (TMAB) were used as additives in several separation buffers to examine the relationship between the analytes and the additives in aqueous and nonaqueous CE. It was concluded that the interaction between the analytes and the additives in this study was mainly due to ion-pairing and that hydrophobic interactions played a minor role. In the final part of this thesis, the effects of multicomponent additives were studied. Sulfobutylether-ß-CD (SBE-ß-CD) and hydroxypropyl-ß-CD (HP-PCD) were used as differently charged additives. Once the interaction between the analytes with each additive was understood, the effects of a mixture of the two differently charged additives were examined.

description: Το Super Bowl- ο τελικός του αμερικανικού ποδοσφαίρου- είναι ένα τηλεοπτικό γεγονός παγκοσμίας εμβέλειας, κατά την διάρκεια του οποίου προβάλλονται οι πιο ακριβοπληρωμένες και δημιουργικές διαφημίσεις. Παρ’ όλη την μεγάλη απήχηση του, πολύ λίγες έρευνες έχουν διεξαχθεί σχετικά με το περιεχόμενο των συγκεκριμένων διαφημίσεων. Η παρούσα έρευνα επικεντρώνεται στην ανάλυση περιεχομένου των διαφημίσεων που προβλήθηκαν από το 1969 έως το 2009, με σκοπό την διερεύνηση της αναλογικής συσχέτισης ανάμεσα στην χρήση πληροφοριακού υλικού και δημιουργικών στοιχείων καθώς επίσης και την συγκριτική ανάλυση τόσο σε βραχυχρόνιο όσο και μακροχρόνιο επίπεδο. Τα αποτελέσματα μαρτυρούν με την πάροδο του χρόνου, αύξηση της χρήσης των δημιουργικών στοιχείων εις βάρος του πληροφοριακού υλικού ενώ σημαντική αύξηση παρατηρήθηκε στην χρήση της μουσικής ως κυρίαρχο ή δευτερεύον στοιχείο, στην χρήση του χιούμορ και συγκεκριμένα στην χιουμοριστική υποτίμηση, στην χρήση του σουρεαλιστικού ή φανταστικού σκηνικού, στην χρήση του γυμνού, των παιδιών και των ζώων. Αντιθέτως, μικρές και όχι αξιοσημείωτες μεταβολές σημειώθηκαν στην χρήση των διασημοτήτων και της άμεσης σύγκρισης στις διαφημίσεις του Super Bowl, την παρούσα χρονική περίοδο, ενώ διαχωρισμός πραγματοποιήθηκε ανάμεσα σε μακροχρόνιο και βραχυχρόνιο επίπεδο όσον αφορά στον συσχετισμό της χρήσης πληροφοριακού υλικού και των κατηγοριών προϊόντων, όπως αυτές προσδιορίζονται από την FCB matrix. Ουσιαστικά, αποδείχτηκε η επικράτηση των δημιουργικών στοιχείων που εστιάζουν στην έκκληση στο συναίσθημα (emotional appeals) έναντι του πληροφοριακού υλικού και των λογικών επιχειρημάτων.
description: The Super Bowl, the championship game of the National American Football league, is the most famous television broadcast in all over the world, where the most vraetive commercial takes place. The present study explores the content of commercials, shown during 1969-2009 Super Bowls, trying to investigate the relationship between the use of information context-message-and the creative strategies, using the longitudinal and comparative analysis. The findings suggest that by the time, the use of creative strategies is increased followed by a simultaneous decrease in the use of information context. Specifically, there was an increasement in the use of human and particularly the humorous disparagement, the use of surreal or fantasy visuals, the use of nudity, children and animals. Furthermore, low changes were noticed in the use of celebrities and direcr comparison.

description: Knowledge graph embedding (KGE) has been identified as an effective method for link prediction, which involves predicting missing relations or entities based on existing entities or relations. KGE is an important method for implementing knowledge representation and, as such, has been widely used in driving intelligent applications w.r.t. question-answering systems, recommendation systems, and relationship extraction. Models based on convolutional neural networks (CNNs) have achieved good results in link prediction. However, as the coverage areas of knowledge graphs expand, the increasing volume of information significantly limits the performance of these models. This article introduces a triple-attention-based multi-channel CNN model, named ConvAMC, for the KGE task. In the embedding representation module, entities and relations are embedded into a complex space and the embeddings are performed in an alternating pattern. This approach helps in capturing richer semantic information and enhances the expressive power of the model. In the encoding module, a multi-channel approach is employed to extract more comprehensive interaction features. A triple attention mechanism and max pooling layers are used to ensure that interactions between spatial dimensions and output tensors are captured during the subsequent tensor concatenation and reshaping process, which allows preserving local and detailed information. Finally, feature vectors are transformed into prediction targets for embedding through the Hadamard product of feature mapping and reshaping matrices. Extensive experiments were conducted to evaluate the performance of ConvAMC on three benchmark datasets compared with state-of-the-art (SOTA) models, demonstrating that the proposed model outperforms all compared models across all evaluation metrics on two of the datasets, and achieves advanced link prediction results on most evaluation metrics on the third dataset.
Effects of the Running of the QCD Coupling on the Energy Loss in the Quark-Gluon Plasma

description: Finite temperature modifies the running of the QCD coupling alpha_s(k,T) with resolution k. After calculating the thermal quark and gluon masses selfconsistently, we determine the quark-quark and quark-gluon cross sections in the plasma based on the running coupling. We find that the running coupling enhances these cross sections by factors of two to four depending on the temperature. We also compute the energy loss dE/dx of a high-energy quark in the plasma as a function of temperature. Our study suggests that, beside t-channel processes, inverse Compton scattering is a relevant process for a quantitative understanding of the energy loss of an incident quark in a hot plasma.

description: Colloidal nanocrystal gels can be assembled using a difunctional "linker" molecule to mediate bonding between nanocrystals. The conditions for gelation and the structure of the gel are controlled macroscopically by the linker concentration and microscopically by the linker's molecular characteristics. Here, we demonstrate using a toy model for a colloid-linker mixture that linker flexibility plays a key role in determining both phase behavior and structure of the mixture. We fix the linker length and systematically vary its bending stiffness to span the flexible, semiflexible, and rigid regimes. At fixed linker concentration, flexible-linker and rigid-linker mixtures phase separate at low colloid volume fractions in agreement with predictions of first-order thermodynamic perturbation theory, but the semiflexible-linker mixtures do not. We correlate and attribute this qualitatively different behavior to undesirable "loop" linking motifs that are predicted to be more prevalent for linkers with end-to-end distances commensurate with the locations of chemical bonding sites on the colloids. Linker flexibility also influences the spacing between linked colloids, suggesting strategies to design gels with desired phase behavior, structure, and by extension, structure-dependent properties.

On the geometry of quantum constrained systems

description: The use of geometric methods has proved useful in the hamiltonian description of classical constrained systems. In this note we provide the first steps toward the description of the geometry of quantum constrained systems. We make use of the geometric formulation of quantum theory in which unitary transformations (including time evolution) can be seen, just as in the classical case, as finite canonical transformations on the quantum state space. We compare from this perspective the classical and quantum formalisms and argue that there is an important difference between them, that suggests that the condition on observables to become physical is through the double commutator with the square of the constraint operator. This provides a bridge between the standard Dirac procedure --through its geometric implementation-- and the Master Constraint program.

description: This work is referred to the Museum education. The main objective of this work is the study of a part from our cultural heritage, as well suggested ways for its educational approach. In particular, it includes ways that students (preschools and primary level) could in order to approach Roman Thessalonica. To begin with, we present the aspect of the city during the Roman period. Secondly, there is a presentation of educational programmes that refer to the approaching ways of Greek archaeological cities, either these cities was continuously inhabitable or no. This part is completed with the recording and the coding of these programs. This coding offered a range of basic lines, that constituted the base for our own proposals.

description: We demonstrate the operation of Josephson junction arrays (JJA) driven by optical pulses generated by a mode-locked laser and an optical time-division multiplexer. A commercial photodiode converts the optical pulses into electrical ones in liquid helium several cm from the JJA. The performance of our custom-made mode-locked laser is sufficient for driving a JJA with low critical current at multiple Shapiro steps. Our optical approach is a potential enabler for fast and energy-efficient pulse drive without expensive high-bandwidth electrical pulse pattern generator, and without high-bandwidth electrical cabling crossing temperature stages. Our measurements and simulations motivate an improved integration of photodiodes and JJAs using, e.g., flip-chip techniques, in order to improve both the understanding and fidelity of pulse-driven Josephson Arbitrary Waveform Synthesizers (JAWS).
