description: Η παρούσα εργασία αφορά στην κατάσχεση χρηματικών απαιτήσεων του καθ’ ου η εκτέλεση σε βάρος του τρίτου, ενώ, ειδικότερα, αντικείμενο αυτής αποτελούν τα μέσα προστασίας του κατασχόντος έναντι της αρνητικής ή ανακριβούς δήλωσης του τρίτου. Η εργασία διαρθρώνεται σε δύο μέρη. Στο πρώτο μέρος επιδιώκεται η αποσαφήνιση της κρίσιμης έννοιας της αρνητικής – ανακριβούς δήλωσης, ως προαπαιτούμενου της ενεργοποίησης των εξουσιών του κατασχόντος, η οποία επιχειρείται μέσα από την προσέγγιση του αναγκαίου περιεχομένου της δήλωσης. Στη συνέχεια, εξετάζεται εκτενώς το παραδεκτό της ανακοπής καθώς και οι έννομες συνέπειες της απόφασης που εκδίδεται επί αυτής, ενώ ακολούθως επιχειρείται η προσέγγιση της άμυνας του τρίτου, η οποία εστιάζει στις ενστάσεις που αφορούν στην οφειλή του αλλά και στη δυνατότητα προσβολής της κατάσχεσης που επιβάλλεται στα χέρια του. Το πρώτο μέρος της εργασίας ολοκληρώνεται με την παρουσίαση της αξίωσης αποζημίωσης του κατασχόντος, η οποία επικεντρώνεται στις προϋποθέσεις γέννησης της ευθύνης του τρίτου καθώς και στο ορισμένο της σχετικής αγωγής. Στο δεύτερο μέρος της εργασίας παρατίθενται ειδικές εφαρμογές των ανωτέρω στο πλαίσιο της διοικητικής εκτέλεσης καθώς και της κατάσχεσης στα χέρια της Τράπεζας, του Δημοσίου, των ΟΤΑ και των ΝΠΔΔ ως τρίτων.
description: The subject of the present work is «attachment in the hands of a third party» and particularly the creditor’s protection against the negative or inaccurate declaration of the third party. The work is divided in two parts. In the first part, we clarify the meaning of negative – inaccurate declaration, as a prerequisite for the creditor’s rights exercise, through the examination of its necessary content. Furthermore, it is extensively analyzed the admissibility of caveat against the declaration and the effects of the decision pronounced on it, as well as, the defense of the third party, focused on the objections related to his debt and the validity of garnishment. Last but not least, we present the creditor’s compensation claim and especially the necessary conditions for the obligation of the third party, as well as, the admissibility of the action. In the second part, we focus on the practice of the above mentioned in the context of administrative enforcement and attachment in the hands of a bank, the State, the local authorities and the public entities.
Disorder and the Supersolid State of Solid $^4$He

description: We report torsional oscillator supersolid studies of highly disordered samples of solid $^4$He. In an attempt to approach the amorphous or glassy state of the solid, we prepare our samples by rapid freezing from the normal phase of liquid $^4$He. Less than two minutes is required for the entire process of freezing and the subsequent cooling of the sample to below 1 K. The supersolid signals observed for such samples are remarkably large, exceeding 20 % of the entire solid helium moment of inertia. These results, taken with the finding that the magnitude of the small supersolid signals observed in our earlier experiments can be reduced to an unobservable level by annealing, strongly suggest that the supersolid state exists for the disordered or glassy state of helium and is absent in high quality crystals of solid $^4$He.

description: The cosmic background due to the Sunyaev-Zeldovich (SZ) effect is expected to be the largest signal at mm and cm wavelengths at a resolution of a few arcminutes. We investigate some simple statistics of SZ maps and their scaling with the normalization of the matter power spectrum, sigma_8, as well as the effects of the unknown physics of the intracluster medium on these statistics. We show that the SZ background provides a significant background for SZ cluster searches, with the onset of confusion occurring around 10^{14} h^{-1} solar masses in a cosmology-dependent way, where confusion is defined as typical errors in recovered flux larger than 20%. The confusion limit, corresponds to the mass at which there are roughly ten clusters per square degree, with this number nearly independent of cosmology and cluster gas physics. Typical errors grow quickly as lower mass objects are included in the catalog. We also point out that there is nothing in particular about the rms of the filtered map that makes it especially well-suited for capturing aspects of the SZ effect, and other indicators of the one-point SZ probability distribution function are at least as well suited for the task. For example, the full width at half maximum of the one point probability distribution has a field-to-field scatter that is about 60% that of the rms. The simplest statistics of SZ maps are largely unaffected by cluster physics such aspreheating, although the impact of preheating is clear by eye in the maps.Studies aimed at learning about the physics of the intracluster medium will apparently require more specialized statistical indicators.

description: We study the renormalization of the electron-spin-fluctuation (el-sp) vertex in a two-dimensional Hubbard model with nearest-neighbor (t) and next-nearest-neighbor (t') hopping by a Quantum-Monte-Carlo calculation. Our results show that for t'=0, the renormalized el-sp vertex decreases quite generally with decreasing temperature at all spin-fluctuation momentum transfers. The suppression of the el-sp vertex results in a substantial reduction of the effective pairing interaction mediated by antiferromagnetic spin fluctuations in both the intermediate- and strong-correlation regimes. The inclusion of a finite t'/t<0, increases the Landau damping rate of spin fluctuations, especially in the overdoped region. The increased damping rate leads to smaller vertex corrections, in agreement with earlier diagrammatic calculations. Still, the vertex correction reduces the spin-fermion vertex, as at t'=0.

description: Τα τελευταία χρόνια, λόγω των αυστηρών προδιαγραφών που επιβάλει η Ευρωπαϊκή Ένωση σχετικά με την προστασία του περιβάλλοντος, αυξάνεται συνεχώς το ενδιαφέρον για τη χρήση φυσικών χρωστικών στη βαφή υφάνσιμων ινών. Με τη χρήση φυσικών χρωστικών ελαττώνεται σημαντικά η επιβάρυνση του περιβάλλοντος και η δαπάνη ενέργειας. Στην παρούσα εργασία πραγματοποιήθηκε η βαφή φυσικών αλλά και συνθετικών ινών με τη φυσική χρωστική αννάττο, προερχόμενη από την Ινδία, η οποία είχε τη μορφή λεπτόκοκκης στερεής σκόνης. Η βαφή έγινε σε υποστρώματα από βαμβάκι, μαλλί, νάιλον και πολυεστέρα, έπειτα από προκατεργασία, σε διαφορετικούς τόνους και θερμοκρασίες. Στη συνέχεια, εφαρμόστηκε η τεχνική της υπερδιήθησης στην παραπάνω χρωστική, προς συμπύκνωση και καθαρισμό της, με τη χρήση πολυαιθεροσουλφόνης μεμβράνης. Με το χρώμα που προέκυψε επαναλήφθηκε η προηγούμενη διαδικασία βαφής, υπό τις ίδιες συνθήκες. Τέλος, μελετήθηκαν και αποτιμήθηκαν οι βαφικές ιδιότητες της χρωστικής πριν και μετά την υπερδιήθηση, με τη χρήση της φασματοφωτομετρίας υπεριώδους – ορατού, UV – VIS.
description: Nowadays, there is a growing interest in the use of natural dyes in textile fiber dyeing, due to the strict requirements imposed by the European Union. The use of natural dyes reduces significantly both the energy expenditure and the environmental impact. In the present thesis natural and synthetic fibres underwent dyeing with natural dye annatto, coming from India , and it was in the form of fine powder. The dyeing procedure was performed on different substrates made of cotton, wool, nylon and polyester, after pretreatment, in various depths of shade and temperatures. Then, in order to condensate and clear the above mentioned dye, the technique of ultrafiltration was performed, by the use of a polyethersulphone membrane. The previous dyeing process was repeated, under the same conditions. Finally, the colouring properties of the dye before and after ultrafiltration were studied and evaluated, using ultraviolet - visible spectrophotometry, UV - VIS.

description: Quantum cryptography has been recently extended to continuous variable systems, e.g., the bosonic modes of the electromagnetic field. In particular, several cryptographic protocols have been proposed and experimentally implemented using bosonic modes with Gaussian statistics. Such protocols have shown the possibility of reaching very high secret-key rates, even in the presence of strong losses in the quantum communication channel. Despite this robustness to loss, their security can be affected by more general attacks where extra Gaussian noise is introduced by the eavesdropper. In this general scenario we show a "hardware solution" for enhancing the security thresholds of these protocols. This is possible by extending them to a two-way quantum communication where subsequent uses of the quantum channel are suitably combined. In the resulting two-way schemes, one of the honest parties assists the secret encoding of the other with the chance of a non-trivial superadditive enhancement of the security thresholds. Such results enable the extension of quantum cryptography to more complex quantum communications.

description: In mixed datasets, with multiple species or subgenomes, such as found in metagenomics sequencing or study of polyploid genomes, the tasks of error detection and correction are made difficult by the significant variation in the data. Due to the presence of reads from homologous sequences, the correct bases, including SNPs, can have unusually low rates of occurrence.

Our work is focused on the development of novel approaches for error identification. The starting point is a base analytic approach which attempts to account for variation by introducing similarity weights. The main tool for improvement are two machine learning models with over 99% accuracy that can be combined with any other error detection approach as an additional filter to reduce the false positives among predicted errors. When compared to use of frequencies, their combination halves the number of corrections by reducing false positives.

Τα δεδομένα έχουν ληφθεί από την Έρευνα Εισοδήματος και Συνθηκών Διαβίωσης της Eurostat, καθώς επίσης και από την ΕΛΣΤΑΤ, τα Η.Ε., τον ΟΟΣΑ και το Παγκόσμιο Οικονομικό Φόρουμ. Έχει εξεταστεί η έμφυλη διάσταση της σχετικής φτώχειας στην Ελλάδα διαχρονικά και το φαινόμενο της θηλυκοποίησης της φτώχειας. Παρατηρήθηκε μία μικρή αύξηση της φτώχειας των γυναικών στην Ελλάδα, σύμφωνα με τα ποσοτικά δεδομένα, η οποία όμως αποδίδεται στη χρήση ενός σχετικού ορισμού της φτώχειας και η διαφορά του αριθμού των γυναικών σε κίνδυνο φτώχειας ως προς τον αριθμό των αντρών σε όλα τα εξεταζόμενα έτη έδειξε μία ασθενή μεν, αλλά υπάρχουσα διαδικασία θηλυκοποίησης της φτώχειας στην Ελλάδα. Για τη λήψη πιο αξιόπιστων αποτελεσμάτων σχετικά με τη φτώχεια των γυναικών προτείνεται για τη μέτρησή της να γίνεται χρήση όχι μόνο χρηματικών/εισοδηματικών δεικτών αλλά και δεικτών έμφυλης ανισότητας. Τέλος, για την εξαγωγή ασφαλέστερων συμπερασμάτων σχετικά με τη διαδικασία της θηλυκοποίησης της φτώχειας κρίνεται καλό να επαναληφθεί η μελέτη στα επόμενα χρόνια.
description: In this master thesis, the phenomenon of women’s poverty in Greece is analyzed during 2003-2012, observing the impacts of the crisis on it, as well. The data was retrieved from the Survey on Income and Living Conditions of the Eurostat and also the Elstat, the U.N., the OECD and the Global Economic Forum (WEF). The evolution of relative poverty in Greece was examined from a gender perspective and the feminization of poverty was examined as well. A slight increase of women’s poverty in Greece was observed, in accordance with the quantitative data, which is attributed to the use of a relative definition of poverty and the difference in the at-risk poverty levels of women and men during all the years under research was significant enough to prove a weak but existing process of feminization of poverty in Greece. The use of gender inequality indices is suggested in combination with monetary ones so as to receive more reliable results. It is also considered good to repeat the study in the upcoming years for receiving more valid conclusions about the process of feminization of poverty in Greece.

description: We have exploited the large area coverage of the combined UKIDSS Ultra Deep Survey (UDS) and Subaru/XMM-Newton Deep Survey (SXDS) to search for bright Lyman-break galaxies (LBGs) at z >= 5. Using the available optical+near-infrared photometry to efficiently exclude low-redshift contaminants, we identify nine z >= 5 LBG candidates brighter than z'=25(AB) within the 0.6 square degree overlap region between the UDS early data release (EDR) and the optical coverage of the SXDS. Accounting for selection incompleteness, we estimate the corresponding surface density of z >= 5 LBGs with z'<=25(AB) to be 0.005+/-0.002 per square arcmin. Modelling of the optical+near-infrared photometry constrains the candidates' redshifts to lie in the range 5.1 < z < 5.9, and provides estimates for their stellar masses. Although the stellar mass estimates are individually uncertain, a stacking analysis suggests that the typical stellar mass of the LBG candidates is >~5x10^10 Msun which, if confirmed, places them amongst the most massive galaxies currently known at z >= 5. It is found that Lambda CDM structure formation can produce sufficient numbers of dark matter halos at z >= 5 to accommodate our estimated number density of massive LBGs for plausible values of sigma_8 and the ratio of stellar to dark matter. Moreover, it is found that recent galaxy formation models can also account for the existence of such massive galaxies at z >= 5. Finally, no evidence is found for the existence of LBGs with stellar masses in excess of ~3x10^11 Msun at this epoch, despite the large co-moving volume surveyed.

For this, we refine the previously formulated diagrammatic rules for computing the 1/ N expansion of the nonmixed correlation functions and give a new formulation of the spectral curve. We extend these rules obtaining a closed formula for correlation functions in all orders of topological expansion. We then integrate it to obtain the free energy in terms of residues on the associated Riemann surface.

description: We study monodromy defects in $O(N)$ symmetric scalar field theories in $d$ dimensions. After a Weyl transformation, a monodromy defect may be described by placing the theory on $S^1\times H^{d-1}$, where $H^{d-1}$ is the hyperbolic space, and imposing on the fundamental fields a twisted periodicity condition along $S^1$. In this description, the codimension two defect lies at the boundary of $H^{d-1}$. We first study the general monodromy defect in the free field theory, and then develop the large $N$ expansion of the defect in the interacting theory, focusing for simplicity on the case of $N$ complex fields with a one-parameter monodromy condition. We also use the $ε$-expansion in $d=4-ε$, providing a check on the large $N$ approach. When the defect has spherical geometry, its expectation value is a meaningful quantity, and it may be obtained by computing the free energy of the twisted theory on $S^1\times H^{d-1}$. It was conjectured that the logarithm of the defect expectation value, suitably multiplied by a dimension dependent sine factor, should decrease under a defect RG flow. We check this conjecture in our examples, both in the free and interacting case, by considering a defect RG flow that corresponds to imposing alternate boundary conditions on one of the low-lying Kaluza-Klein modes on $H^{d-1}$. We also show that, adapting standard techniques from the AdS/CFT literature, the $S^1\times H^{d-1}$ setup is well suited to the calculation of the defect CFT data, and we discuss various examples, including one-point functions of bulk operators, scaling dimensions of defect operators, and four-point functions of operator insertions on the defect.

description: We study the development of electron-electron correlations in circular quantum dots as the density is decreased. We consider a wide range of both electron number, N<=20, and electron gas parameter, r_s<18, using the diffusion quantum Monte Carlo technique. Features associated with correlation appear to develop very differently in quantum dots than in bulk. The main reason is that translational symmetry is necessarily broken in a dot, leading to density modulation and inhomogeneity. Electron-electron interactions act to enhance this modulation ultimately leading to localization. This process appears to be completely smooth and occurs over a wide range of density. Thus there is a broad regime of ``incipient'' Wigner crystallization in these quantum dots. Our specific conclusions are: (i) The density develops sharp rings while the pair density shows both radial and angular inhomogeneity. (ii) The spin of the ground state is consistent with Hund's (first) rule throughout our entire range of r_s for all 4

The application of hypertext to archives
Creators: name: Taylor, Blair
Publisher: name: University of British Columbia
Year: 2009

description: The thesis explores whether hypertext, a non-linear, associative way of structuring information using computer programs, could be implemented in an archival information system. It includes a summary of the development and nature of hypertext, a discussion of archival information systems and the needs of users regarding information retrieval, and a discussion of how the capacities of hypertext can be applied to archival retrieval systems and how a possible hypertext retrieval system could be structured. Additionally, aspects of a hypothetical hypertext information system are presented to illustrate how archival information could be organized using hypertext and how that information could be browsed and retrieved. There are both benefits and disadvantages to implementing a hypertext archival retrieval system. The advantages of such a system include the following: the hierarchical structure of information about archives is well suited to being represented in hypertext; movement throughout the hierarchical structures is as simple as following links between the records; records could have multiple links to other records; information could be structured in multiple ways simultaneously; associative browsing of the information by following the links between the records could be possible; and a variety of search options are possible that would allow users to access the information in the hypertext in a variety of ways. The disadvantages of implementing a hypertext archival information system are: it might be too time consuming to create the hypertext; movement throughout the hypertext network would rely on links that were created by the archivist, so navigation would only be as good or bad as the established links; and the associational, non-linear structure of hypertext might not be the most effective or efficient way to retrieve archival information. Despite some of the disadvantages and technical difficulties of hypertext, it could be successfully implemented in an archival retrieval system. The configuration and functions of such a system could vary widely, and would depend on the requirements of the archives.

description: We have recently shown that there is a limit to quantum coherence in many-particle spin qubits due to spontaneous symmetry breaking. These results were derived for the Lieb-Mattis spin model. Here we will show that the underlying mechanism of decoherence in systems with spontaneous symmetry breaking is in fact more general. We present here a generic route to finding the decoherence time associated with spontaneous symmetry breaking in many particle qubits, and subsequently we apply this approach to two model systems, indicating how the continuous symmetries in these models are spontaneously broken and discussing the relation of this symmetry breaking to the thin spectrum. We then present in detail the calculations that lead to the limit to quantum coherence, which is due to energy shifts in the thin spectrum.

description: In this paper, we present results of our calculations on the effects of next to nearest neighbor boson hopping ($t^{\prime}$) energy on Bose-Einstein condensation in cubic lattices. We consider both non-interacting and repulsively interacting bosons moving in the lowest Bloch band. The interacting bosons are studied making use of the Bogoliubov method. We find that the bose condensation temperature is enhanced with increasing $t^{\prime}$ for bosons in a simple cubic (sc) lattice and decreases for bosons in body-centered cubic (bcc) and face-centered cubic (fcc) lattices. We also find that interaction induced depletion of the condensate is reduced for bosons in a sc lattice while is enhanced for bosons in bcc and fcc lattices.

Cubic Dresselhaus Spin-Orbit Coupling in 2D Electron Quantum Dots

name: Halperin, Bertrand I.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We study effects of the oft-neglected cubic Dresselhaus spin-orbit coupling (i.e., $\propto p^3$) in GaAs/AlGaAs quantum dots. Using a semiclassical billiard model, we estimate the magnitude of the spin-orbit induced avoided crossings in a closed quantum dot in a Zeeman field. Using these results, together with previous analyses based on random matrix theory, we calculate corresponding effects on the conductance through an open quantum dot. Combining our results with an experiment on conductance through an 8 um^2 quantum dot [D M Zumbuhl et al., Phys. Rev. B 72, 081305 (2005)] suggests that 1) the GaAs Dresselhaus coupling constant, $γ$, is approximately 9 eVA^3, significantly less than the commonly cited value of 27.5 eVA^3 and 2) the majority of the spin-flip component of spin-orbit coupling can come from the cubic Dresselhaus term.

The Localized Quantum Vacuum Field
Creators: name: Dragoman, Daniela
Publisher: name: arXiv
Year: 2006
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A model for the localized quantum vacuum is proposed in which the zero-point energy of the quantum electromagnetic field originates in energy- and momentum-conserving transitions of material systems from their ground state to an unstable state with negative energy. These transitions are accompanied by emissions and re-absorptions of real photons, which generate a localized quantum vacuum in the neighborhood of material systems. The model could help resolve the cosmological paradox associated to the zero-point energy of electromagnetic fields, while reclaiming quantum effects associated with quantum vacuum such as the Casimir effect and the Lamb shift; it also offers a new insight into the Zitterbewegung of material particles.

description: The random sequential adsorption (RSA) model has served as a paradigm for diverse phenomena in physical chemistry, as well as in other areas such as biology, ecology, and sociology. In the present work, we survey aspects of the RSA model with emphasis on the approach to and properties of jammed states obtained for large times in continuum deposition versus that on lattice substrates, and on pre-patterned surfaces. The latter model has been of recent interest in the context of efforts to use pre-patterning as a tool to improve selfassembly in micro- and nanoscale surface structure engineering.

description: We report on an intrinsic relationship between the maximum-likelihood quantum-state estimation and the representation of the signal. A quantum analogy of the transfer function determines the space where the reconstruction should be done without the need for any ad hoc truncations of the Hilbert space. An illustration of this method is provided by a simple yet practically important tomography of an optical signal registered by realistic binary detectors.

What are you doing it for? Realist writing – the riddled boundary that divides fiction and reality

subject: Other creative arts and writing not elsewhere classified

description: In this essay, I respond to Australian author Charmian Clift’s question about writing: ‘what are you doing it for?’ (Wheatley 2022, 291). This question is the title of one of Clift’s essays, from a collection of narrative-driven essays, written for the Women’s Pages of The Sydney Morning Herald, after Clift’s return to Australia in 1964. I consider the similarities between realist fiction and writing that (by classification) purports to bear a closer allegiance to the author’s autobiographical life. I understand realist writing to be a representation of living | memory – the complicated and multi-faceted nature of our interior selfhood. This essay reflects my preoccupation with the cartwheels of our inner consciousness as it relates to what-I-write | how-I-write | why-I-write, and how we engage with the work of others, both writers we know in the everyday, and writers we ‘know’ through the page. I consider the act of producing narrative as a sensate response to enigma, a creative response to rumination and (perhaps) an antidote to ongoing rumination – shirking the discussion about autobiography in favour of a discussion about impetus – considering writing as a reflection upon the operations (and inherent conundrums) of an interior consciousness.

description: We present an axiomatic modification of quaternionic quantum mechanics with a possible-worlds semantics capable of predicting essential "nonquantum" features of an observable universe model - the dimensionality and topology of spacetime, the existence, the signature and a specific form of a metric on it, and certain naturally distinguished directions (vistas) in spacetime unrelated to its metric properties.

Collective modes of a quasi two-dimensional Bose condensate in large gas parameter regime

description: We have theoretically studied the collective modes of a quasi two-dimensional (Q2D) Bose condensate in the large gas parameter regime by using a formalism which treats the interaction energy beyond the mean-field approximation. In the calculation we use the perturbative expansion for the interaction energy by incorporating the Lee, Huang and Yang (LHY) correction term. The results show that incorporation of this higher order term leads to detectable modifications in the mode frequencies.

Exploring the evolutionary significance of mitochondrial genetic variation in Drosophila melanogaster

Publisher: name: Figshare
Year: 2019
Subjects: subject: Evolutionary Biology
subject: FOS: Biological sciences

description: My PhD thesis examined the contribution of sequence variation in the mitochondrial DNA to the expression of core phenotypic traits in the fruit flies. My findings provide new evidence to suggest that the mitochondrial genome accrues mutations with sexually antagonistic effects on the metabolic rate. These same mutations appear to underpin trade-offs in energy allocations across different physiological and life-history traits. I have also examined the capacity for environmental heterogeneity to modulate the link between mitochondrial genotype and phenotype, confirming the role of dietary protein-carbohydrate balance in mediating the effect of mitochondrial genotype on longevity.
Neutron Stars in Palatini $R+αR^2$ and $R+αR^2+βQ$ Theories

description: We study solutions of the stellar structure equations for spherically symmetric objects in Palatini $f(R)=R+αR^2$ and $f(R,Q)=R+αR^2+βQ$ in the mass-radius region associated to neutron stars. We illustrate the potential impact of the $R^2$ and $Q$ terms by studying a range of viable values of $α$ and $β$. Similarly, we use different equations of state (SLy, FPS, HS(DD2) and HS(TMA)) as a simple way to account for the equation of state uncertainty. Our results show that for certain combinations of the $α$ and $β$ parameters and equation of state, the effect of modifications of general relativity on the properties of stars is sizeable. Therefore, with increasing accuracy in the determination of the equation of state for neutron stars, astrophysical observations may serve as discriminators of modifications of General Relativity.

description: It is shown that the non-associative operators in a non-associative quantum theory are unobservables. The observable quantity may be presented only by the elements of some associative subalgebra. It is shown that the elements of the associative subalgebra are extended objects that can be similar to strings. It is assumed that the non-associative quantum field theory can be applied to the quantization of strongly interacting fields. The method for obtaining field equations in a non-associative case is given.

Effective boundary conditions for dense granular flows

description: We derive an effective boundary condition for granular flow taking into account the effect of the heterogeneity of the force network on sliding friction dynamics. This yields an intermediate boundary condition which lies in the limit between no-slip and Coulomb friction; two simple functions relating wall stress, velocity, and velocity variance are found from numerical simulations. Moreover, we show that this effective boundary condition corresponds to Navier slip condition when GDR MiDi's model is assumed to be valid, and that the slip length depends on the length scale that characterises the system, \emph{viz} the particle diameter.

description: We present the UV spectroscopy and timing of three nearby pulsars (Vela, B0656+14 and Geminga) recently observed with the Space Telescope Imaging Spectrograph. We also review the optical and X-ray properties of these pulsars and establish their connection with the UV properties. We show that the multiwavelengths properties of neutron stars (NSs) vary significantly within the sample of middle-aged pulsars. Even larger differences are found between the thermal components of Ge-minga and B0656+14 as compared to those of radio-quiet isolated NSs. These differences could be attributed to different properties of the NS surface layers.
