description: Το αντικείμενο της εργασίας ήταν η διερεύνηση των υφιστάμενων εργασιακών δομών και ο τρόπος εξέλιξης της απασχόλησης (είσοδος στο επάγγελμα, κατάρτιση, σταδιοδρομία, λήξη απασχόλησης). Μελετήθηκαν επίσης κάποια από τα κύρια χαρακτηριστικά του επαγγέλματος, οι προκύπτουσες δυσκολίες αλλά και η συνδικαλιστική οργάνωση των εργαζόμενων. Αρχικά γίνεται εισαγωγή στις δύο συνιστώσες της εργασίας, αφενός στο σύστημα των μεταφορών, γενικότερα αλλά και ειδικότερα για τις εμπορευματικές μεταφορές, και αφετέρου στον ανθρώπινο παράγοντα. Ακολούθως μελετάται το κάθε υποσύστημα μεταφορών αφού κρίθηκε σκόπιμος ο διαχωρισμός του κλάδου (οδικές, σιδηροδρομικές, θαλάσσιες, αεροπορικές εμπορευματικές μεταφορές). Στην τελευταία συμπερασματική ενότητα, χρησιμοποιώντας τη μέθοδο της ανάλυσης S.W.O.T. παρουσιάζονται τα προκύπτοντα συμπεράσματα σχετικά με την εργασιακή απασχόληση ανά υποσύστημα μεταφορών. Με βάση αυτά τα αποτελέσματα προκύπτουν συμπεράσματα και προτάσεις που αφορούν την απασχόληση γενικότερα στον κλάδο των εμπορευματικών μεταφορών.
description: The subject of the thesis is the investigation of the existing labour structures and the way employment evolves (entrance in the profession, development, end of carreer). Some of the main aspects of the employment are also examined, as well as resulting difficulties but also the way unions are organised. Initially a reference in the two components of the thesis is presented. Firstly, there is an introduction in the transport system (general and freight transport), and secondly in the human factor. Furthermore, every modal (roads, railways, maritime, air) is examined as it was deemed necessary the distinction of the transport system in order to study separately and better the particularities of each modal. In the last section, using the method of analysis S.W.O.T. are quoted the resulting conclusions of the thesis in regards to the terms of employment per each modal of freight transportation.
Particle displacements in the elastic deformation of amorphous materials: local fluctuations vs. non-affine field

description: We study the local disorder in the deformation of amorphous materials by decomposing the particle displacements into a continuous, inhomogeneous field and the corresponding fluctuations. We compare these fields to the commonly used non-affine displacements in an elastically deformed 2D Lennard-Jones glass. Unlike the non-affine field, the fluctuations are very localized, and exhibit a much smaller (and system size independent) correlation length, on the order of a particle diameter, supporting the applicability of the notion of local "defects" to such materials. We propose a scalar "noise" field to characterize the fluctuations, as an additional field for extended continuum models, e.g., to describe the localized irreversible events observed during plastic deformation.

description: RX J1301.9+2747 is an ultrasoft active galactic nucleus (AGN) with unusual X-ray variability that is characterized by a long quiescent state and a short-lived flare state. The X-ray flares are found to recur quasi-periodically on a timescale of 13-20 ks. Here, we report the analysis of the light curve in the quiescent state from two XMM observations spanning 18.5 years, along with the discovery of a possible quasi-periodic X-ray oscillation (QPO) with a period of ~1500s. The QPO is detected at the same frequency in the two independent observations, with a combined significance of >99.89%. The QPO is in agreement with the relation between frequency and black hole mass (M_BH) that has been reported in previous works for AGNs and Galactic black hole X-ray binaries (XRBs). The QPO frequency is stable over almost two decades, suggesting that it may correspond to the high-frequency type found in XRBs and originates, perhaps, from a certain disk resonance mode. In the 3:2 twin-frequency resonance model, our best estimate on the M_BH range implies that a maximal black hole spin can be ruled out. We find that all ultrasoft AGNs reported so far display quasi-periodicities in the X-ray emission, suggesting a possible link on the part of the extreme variability phenomenon to the ultrasoft X-ray component. This indicates that ultrasoft AGNs could be the most promising candidates in future searches for X-ray periodicities.

description: Η επιστήμη της διαδερμικής χορήγησης φαρμάκου παρουσιάζεται σαν μία πολύπλοκη, αλλά συγχρόνως πολύ ενδιαφέρουσα προοπτική. Αποφεύγοντας τις επεμβατικές μεθόδους και τις επιπλοκές από το γαστρεντερικό, η διαδερμική χορήγηση φαρμάκου μπορεί να βελτιώσει το θεραπευτικό αποτέλεσμα, διατηρώντας ικανοποιητικά επίπεδα της δραστικής ουσίας στον ιστό-στόχο και μειώνοντας τις παρενέργειες στον υπόλοιπο οργανισμό. Αξιοσημείωτες ερευνητικές προσπάθειες έχουν γίνει σε αυτόν τον τομέα τα τελευταία χρόνια, και έχουν αναπτυχθεί αρκετές στρατηγικές για την ενίσχυση της δερματικής διαπερατότητας. Το σύστημα που παρουσιάζει την πιο συχνή χρήση, προσφέροντας διάφορες κλινικές εφαρμογές, είναι το δερματικό έμπλαστρο (patch).Έχουν περιγραφεί αρκετές τοπικές και διαδερμικές μέθοδοι, περιλαμβάνοντας τη χρήση κατάλληλων γαληνικών μορφών, υπέρκορων συστημάτων, χημικών ενισχυτών της διαπερατότητας, νανοσυστημάτων μεταφοράς ουσιών όπως τα μικρογαλακτώματα, λιποσώματα, και άλλα νανοσωματίδια. Έχουν επίσης προταθεί νέες φυσικές μέθοδοι όπως οι διατάξεις μικρο-ακίδων, τα συστήματα laser, η ηλεκτροφόρηση, η ιοντοφόρηση, τα συστήματα υπερήχων κ.ά.Οι μέθοδοι αυτές επεκτείνονται σε ένα ευρύ πεδίο εφαρμογών, ενώ οι ερευνητές σε όλον τον κόσμο προσπαθούν να βρουν νέες λύσεις, βελτιώνοντας την αποτελεσματικότητα και μειώνοντας παράλληλα τις ανεπιθύμητες ενέργειες.
description: The science of administering drugs through the skin is a complex but also very interesting opportunity. By avoiding issues related to invasive methods or the effects on the gastrointestinal tract and first-pass metabolism, topical and transdermal delivery can enhance therapeutic efficacy while maintaining effective levels.Considerable research efforts have been made in this area and a lot of strategies for enhancing skin penetration have been developed over the last few years. The most commonly used system for this type of delivery is the skin patch, providing various applications. Several topical and transdermal delivery technologies are described including the use of suitable formulations, carriers of nanoparticles such as microemulsions and liposomes, chemical penetration enhancers and supersaturated systems. New physical methods are also proposed such as micro-needle arrays, laser systems, iontophoresis, sonophoresis, and others. The possibilities for this sector are quite broad while researchers around the world are trying to find new solutions improving the efficiency, safety and convenience and decreasing side effects.

description: This is a report of our recent investigation on the extremal dilatonic black holes in four dimensional Gauss-Bonnet gravity. We found that a global solution can exist only when the dilaton coupling is less than a critical value which can be determined numerically. Moreover, the black hole horizon is stretched by the Gauss-Bonnet correction and the entropy is twice the value given by Bekenstein-Hawking formula.

description: Στην παρούσα μεταπτυχιακή εργασία αναλύεται η πολιτική φιλοσοφία των δύο μεγαλύτερων στοχαστών της αρχαιότητας του Πλάτωνα και του Αριστοτέλη. Με βάση τη θεωρία των Ιδεών, ο Πλάτων ανέπτυξε τη σκέψη ότι ο ηθικός αξιολογικός καθορισμός θα διαφωτίσει όλη την περιοχή της ανθρώπινης ζωής. Για τον Πλάτωνα το ηθικό ιδεώδες γίνεται πολιτικό και αυτό αναπτύσσεται κατεξοχήν στην 'Πολιτεία', όπου ο φιλόσοφος εκθέτει ένα σύστημα αρετών στο ιδανικό κράτος. Στον Αριστοτέλη, η έννοια της λογικής είναι η μορφή που προσιδιάζει στην ανθρώπινη ψυχή. Ο άνθρωπος γίνεται ευτυχισμένοςόταν αναπτύσσει την έλλογη και κατ' αρετήν δραστηριότητα που προσιδιάζει στη φύση του. Η ηθική ικανότητα του ανθρώπου, που είναι το κατεξοχήν ζώον πολιτικόν, μόνο στη συλλογική ζωή μπορεί να βρει την τελείωσή της. Ο Αριστοτέλης ενδιαφέρθηκε για τη σταθερότητα της "πολιτείας" με την ύπαρξη μιας εύρωστης μεσαίας τάξης.
description: Plato developed a comprehensive philosophy built around a central metaphysical theory, the Theory of forms, which had implications for science, politics and ethics. Plato was a systematic thinker who set the pattern of philosophy as a comprehensive explanation of all political experience. Plato's argument for justice -"every one fulfills his own duties"- provides not only a theory of ethics but also a model for the ideal state. Aristotle used the notion of logic and developed for the first time the conception of science as a body of Knoeledge having a logical structure. In ethical theory Aristotle argues that the good life for human beings is the life of reason lived "with excellence". He recommends a mixed constitution in politics.

description: Neural Gas (NG) constitutes a very robust clustering algorithm given euclidian data which does not suffer from the problem of local minima like simple vector quantization, or topological restrictions like the self-organizing map. Based on the cost function of NG, we introduce a batch variant of NG which shows much faster convergence and which can be interpreted as an optimization of the cost function by the Newton method. This formulation has the additional benefit that, based on the notion of the generalized median in analogy to Median SOM, a variant for non-vectorial proximity data can be introduced. We prove convergence of batch and median versions of NG, SOM, and k-means in a unified formulation, and we investigate the behavior of the algorithms in several experiments.

description: A contact interaction is used to calculate an array of pion twist-two, -three and -four generalised transverse light-front momentum dependent parton distribution functions (GTMDs). Despite the interaction's simplicity, many of the results are physically relevant, amongst them a statement that GTMD size and shape are largely prescribed by the scale of emergent hadronic mass. Moreover, proceeding from GTMDs to generalised parton distributions (GPDs), it is found that the pion's mass distribution form factor is harder than its electromagnetic form factor, which is harder than the gravitational pressure distribution form factor; the pressure in the neighbourhood of the pion's core is commensurate with that at the centre of a neutron star; the shear pressure is maximal when confinement forces become dominant within the pion; and the spatial distribution of transversely polarised quarks within the pion is asymmetric. Regarding transverse momentum dependent distribution functions (TMDs), their magnitude and domain of support decrease with increasing twist. The simplest Wigner distribution associated with the pion's twist-two dressed-quark GTMD is sharply peaked on the kinematic domain associated with valence-quark dominance; has a domain of negative support; and broadens as the transverse position variable increases in magnitude.

Leaf respiration in tropical and temperate rainforest tree species : responses to environmental gradients
Creators: name: Kohontissa Wasala, Lasantha Kumara Weerasinghe
Publisher: name: The Australian National University
Year: 2015

description: Among forest biomes, tropical and temperate rainforests often show high rates of net primary production (NPP), with rainforests playing a major role in controlling current and future atmospheric carbon dioxide concentrations, and the total amount of carbon stored in vegetation globally. Quantifying rates of leaf respiration (R) of rainforest species and how changes in environment (e.g. light, short- and long-term changes in temperature (T), gradients in nutrient availability) affect R in rainforest species, is crucial in determining how much carbon dioxide is released now and will be released in the future. In this thesis, I sought to explore the effect of a range of environmental gradients on leaf R rates of rainforest tree species, both under controlled and field conditions. Leaf R in darkness (RD) and in the light (RL) exhibited marked differences between upper and lower canopy position in a tropical rainforest. When measured at prevailing growth T at each site, no systematic differences in RD or RL were evident across thermally contrasting rainforest sites in Australia, or across an elevation gradient from Amazon to Andean sites in Peru. When averaged across all forest sites, 30% light inhibition of leaf R was found. Over the 25-45 degrees Celsius range, the T sensitivity of RD was similar in upper and lower canopy leaves; although the Q10 (i.e. proportional change in leaf RD per 10 degrees Celsius rise in temperature) exhibited a decreasing trend with increasing measuring T, there were no marked differences among the thermally contrasting rainforest sites in the measuring T response. Strong evidence was found that tropical and temperate rainforest plants are equally capable of acclimating leaf RD to different growth Ts, including growth Ts higher than that were normally experiencing in their current habitats. The results suggest that rainforest species may be capable of acclimating leaf respiratory metabolism to increases in growth T associated with future global warming; with the result that warming will not necessarily lead to exponentially higher rates of respiratory carbon dioxide release from temperate and tropical rainforest ecosystems. The field studies in Peru highlighted the fact that variations in soil P availability have no systematic impact on leaf RD of tropical lowland forests; this finding was supported by controlled environment study showing that deficiencies in leaf phosphate did not result in lower rates of leaf RD. Collectively, these findings have implications for vegetation-climate models that seek to predict carbon fluxes between rainforests and the atmosphere.

description: In a recent paper arXiv:0705.3190, we gave a general construction of a para-cocyclic structure on a cosimplex, associated to a so called admissible septuple -- consisting of two categories, three functors and two natural transformations, subject to compatibility relations. The main examples of such admissible septuples were induced by algebra homomorphisms. In this note we provide more general examples coming from appropriate (`locally braided') morphisms of monads.

description: We present and discuss the results of our photometric and spectroscopic monitoring of 2SXPS J173508.4-292958 carried out from April to August 2020. This X-ray source, in the foreground with respect to the Galactic center, brightened in X-rays during 2020, prompting our follow-up optical observations. We found the star to contain a K4III giant with a modest but highly variable Halpha emission, composed by a ~470 km/s wide component with superimposed a narrow absorption, offset by a positive velocity with respect to the giant. No orbital motion is detected for the K4III, showing an heliocentric radial velocity stable at -12(+/-1) km/s. No flickering in excess of 0.005 mag in B band was observed at three separate visits of 2SXPS J173508.4-292958. While photometrically stable in 2016 through 2018, in 2019 the star developed a limited photometric variability, that in 2020 took the form of a sinusoidal modulation with a period of 38 days and an amplitude of 0.12 mag in V band. We argue this variability cannot be ascribed to Roche-lobe filling by the K4III star. No correlation is observed between the photometric variability and the amount of emission in Halpha, the latter probably originating directly from the accretion disk around the accreting companion. While no emission from dust is detected at mid-IR wavelengths, an excess in U-band is probably present and caused by direct emission from the accretion disk. We conclude that 2SXPS J173508.4-292958 is a new symbiotic star of the accreting-only variety (AO-SySt).

description: This project poses the use of torsional antennas to increase the performance of an adaptive wireless pushed-based systems. Three algorithms are examined. In the first one, we devide the degrees of the group clients with the number of the antennas. The second algorithm works as the first one. Furthermore, if an antenna is left without a group, then we do the following steps : firstly, we search for an antenna that has a large number of groups. Then, we take some groups an assign them to the antenna with no groups. In the third algorithm, we assign to each antenna a large group of clients. Each of the two last antennas have a all in all, there are 360 degrees for those groups that have no antenna.

description: We study the mobility edges in a variety of one-dimensional tight binding models with slowly varying quasi-periodic disorders. It is found that the quasi-periodic disordered models can be approximated by an ensemble of periodic models. The mobility edges can be determined by the overlaps of the energy bands of these periodic models. We demonstrate that this method provides an efficient way to find out the precise location of mobility edge in qusi-periodic disordered models. Based on this approximate method, we also propose an index to indicate the degree of localization of each eigenstate.

description: We propose an invariant see-saw (ISS) approach to model building, based on the observation that see-saw models of neutrino mass and mixing fall into basis invariant classes labelled by the Casas-Ibarra $R$-matrix, which we prove to be invariant not only under basis transformations but also non-unitary right-handed neutrino transformations $S$. According to the ISS approach, given any see-saw model in some particular basis one may determine the invariant $R$ matrix and hence the invariant class to which that model belongs. The formulation of see-saw models in terms of invariant classes puts them on a firmer theoretical footing, and allows different see-saw models in the same class to be related more easily, while their relation to the $R$-matrix makes them more easily identifiable in phenomenological studies. We also present an ISS mass formula which may be useful in model building. To illustrate the ISS approach we show that sequential dominance (SD) models form basis invariant classes in which the $R$-matrix is approximately related to a permutation of the unit matrix, and quite accurately so in the case of constrained sequential dominance (CSD) and tri-bimaximal mixing. Using the ISS approach we discuss examples of models in which the mixing naturally arises (at least in part) from the charged lepton or right-handed neutrino sectors and show that they are in the same invariant class as SD models. We also discuss the application of our results to flavour-dependent leptogenesis where we show that the case of a real $R$ matrix is approximately realized in SD, and accurately realized in CSD.

description: Η παρούσα εργασία μελετά τον τρόπο και το βαθμό επίδρασης των γλωσσοδιδακτικών προσεγγίσεων που κυριάρχησαν στη διεθνή βιβλιογρα-φία κατά τις τελευταίες δεκαετίες στη διδασκαλία της γλώσσας στην Ισπα-νία. Η έρευνα επικεντρώνεται στην πρώτη τάξη της δευτεροβάθμιας εκπαί-δευσης. Συγκεκριμένα, παρουσιάζονται οι βασικότερες αρχές των ακόλου-θων προσεγγίσεων: της παραδοσιακής οπτικής, του κινήματος της ολικής γλώσσας, του γραψίματος ως διαδικασίας, της γλωσσικής επίγνωσης, της ε-πικοινωνιακής αντίληψης, της παιδαγωγικής του γραμματισμού με βάση τα κειμενικά είδη και άλλων εκδοχών της κειμενοκεντρικής αντίληψης, του κρι-τικού γραμματισμού, των πολυγραμματισμών και της αθροιστικής λογικής. Επίσης, γίνεται μία σύντομη ανασκόπηση των τάσεων που επικράτησαν τα τελευταία χρόνια στη διδασκαλία της λογοτεχνίας, καθώς στην Ισπανία το γλωσσικό μάθημα και το μάθημα της λογοτεχνίας είναι ενοποιημένα. Ως ερευνητικό εργαλείο επιλέχθηκε η μέθοδος της ποιοτικής ανάλυσης. Από την έρευνα προέκυψε ότι, πράγματι, η διδασκαλία της γλώσσας στην Ισπα-νία έχει επηρεαστεί ως ένα βαθμό από τις διεθνείς εξελίξεις. Ωστόσο, οι διάφορες προσεγγίσεις δεν έχουν υιοθετηθεί αυτούσιες, αλλά έχουν ανα-μειχθεί μεταξύ τους και έχουν προσαρμοστεί στην ισπανική πραγματικότη-τα, προκειμένου να καλύψουν τις ανάγκες της τοπικής κοινωνίας.
description: The present study examines the way and the extent to which the approaches to language teaching that prevailed in the international bibliography during the last decades have affected language teaching in Spain. The research focuses on the first grade of the secondary education. Specifically, there are being intro-duced the basic principles of the following approaches: traditional approach, whole language approach, process writing, language awareness, communicative ap-proach, genre-based literacy and other text-based approaches, critical literacy, mul-tiliteracies and cumulative approach. Also, there is a brief presentacion of the ten-dencies that prevailed during the last decades in literature teaching, as in Spain the courses of language and literature are integrated. As research tool is being used the method of quantitative analysis. The research shows that, indeed, lan-guage teaching in Spain has been influenced by the international processes, at least to a degree. However, these approaches are not adopted «uncut», but they have been mixed together and have adapted to spanish reality, in order to cover the neccessities of the local community.

description: The Polyakov loop extended Nambu--Jona-Lasinio (PNJL) model with imaginary chemical potential is studied. The model possesses the extended ${\mathbb Z}_{3}$ symmetry that QCD does. Quantities invariant under the extended ${\mathbb Z}_{3}$ symmetry, such as the partition function, the chiral condensate and the modified Polyakov loop, have the Roberge-Weiss (RW) periodicity. The phase diagram of confinement/deconfinement transition derived with the PNJL model is consistent with the RW prediction on it and the results of lattice QCD. The phase diagram of chiral transition is also presented by the PNJL model.

description: Linear homogeneous recurrence equations with polynomial coefficients are said to be holonomic. Such equations have been introduced in the last century for proving and discovering combinatorial and hypergeometric identities. Given a field K of characteristic zero, a term a(n) is called hypergeometric with respect to K, if the ratio a(n+1)/a(n) is a rational function over K. The solutions space of holonomic recurrence equations gained more interest in the 1990s from the well known Zeilberger's algorithm. In particular, algorithms computing the subspace of hypergeometric term solutions which covers polynomial, rational, and some algebraic solutions of these equations were investigated by Marko Petkovšek (1993) and Mark van Hoeij (1999). The algorithm proposed by the latter is characterized by a much better efficiency than that of the other; it computes, in Gamma representations, a basis of the subspace of hypergeometric term solutions of any given holonomic recurrence equation, and is considered as the current state of the art in this area. Mark van Hoeij implemented his algorithm in the Computer Algebra System (CAS) Maple through the command $LREtools[hypergeomsols]$. We propose a variant of van Hoeij's algorithm that performs the same efficiency and gives outputs in terms of factorials and shifted factorials, without considering certain recommendations of the original version. We have implementations of our algorithm for the CASs Maxima and Maple. Such an implementation is new for Maxima which is therefore used for general-purpose examples. Our Maxima code is currently available as a third-party package for Maxima. A comparison between van Hoeij's implementation and ours is presented for Maple 2020. It appears that both have the same efficiency, and moreover, for some particular cases, our code finds results where $LREtools[hypergeomsols]$ fails.

Seismic shear response of rc members with varying ductility
Creators: name: Roux, Scott
Publisher: name: University of British Columbia
Year: 2009

description: Experimental results of twelve reinforced concrete specimens subjected to reverse cyclic shear are presented. The tests were performed as part of a long-term research program that is presently underway at the University of British Columbia to develop a rational model for seismic shear design. The main objective of this investigation was to test reinforced concrete specimens under well-defined loading conditions in order to provide insight into the behaviour of structural members subjected to reverse cyclic shear. A secondary objective was to develop a scheme to obtain a comprehensive record of crack patterns and deformations. Enhancements made to both the experimental documentation and the specimen boundary conditions are described. A number of parameters are investigated to examine their effect on a reinforced concrete member's behaviour during reverse cyclic shear. The influence of shear span (the ratio of maximum bending moment to shear), amount of transverse reinforcement, axial load (tension and compression), and the presence of distributed longitudinal reinforcing steel are examined. It is apparent that decreasing the shear span will result in a reduction of the amount of flexural ductility exhibited by a member whereas increasing the amount of transverse reinforcement improves both crack control and flexural ductility. It is also apparent that adding axial compression increases the shear capacity of a reinforced concrete element and reduces crack angles, whereas applied axial tension results in increased crack inclinations and a reduced shear capacity. The addition of distributed reinforcing steel was found to enhance crack control and resulted in improved energy dissipation. Experimental results are compared to initial and final shear capacity predictions made using ATC-6-2 provisions. Based on the favourable agreement between the experimental and predicted shear capacities, it appears that the model successfully captures the degradation of shear strength with increased ductility demands. However, although the ATC-6-2 provisions using the simplified "Vc+Vs" method for calculating shear strength provided reasonable estimates of the initial and final shear strengths, perhaps a more refined, rational method of calculating shear resistance, such as the Modified Compression Field Theory, would improve the predictions and provide greater insight into the mechanisms present during reverse cyclic shear.

How does an external electric field trigger the Cassie-Baxter-Wenzel wetting transition on a textured surface?

description: Understanding the critical condition and mechanism of the droplet wetting transition between Cassie-Baxter state and Wenzel state triggered by an external electric field is of considerable importance because of its numerous applications in industry and engineering. However, such a wetting transition on a patterned surface is still not fully understood, e.g., the effects of electro-wetting number, geometry of the patterned surfaces, and droplet volume on the transition have not been systematically investigated. In this paper, we propose a theoretical model for the Cassie-Baxter- Wenzel wetting transition triggered by applying an external voltage on a droplet placed on a mircopillared surface or a porous substrate. It is found that the transition is realized by lowering the energy barrier created by the intermediate composite state considerably, which enables the droplet to cross the energy barrier and complete the transition process. Our calculations also indicate that for fixed droplet volume, the critical electrowetting number (voltage) will increase (decrease) along with the surface roughness for a micro-pillar patterned (porous) surface, and if the surface roughness is fixed, a small droplet tends to ease the critical electrowetting condition for the transition. Besides, three dimensional phase diagrams in terms of electrowetting number, surface roughness, and droplet volume are constructed to illustrate the Cassie-Baxter-Wenzel wetting transition. Our theoretical model can be used to explain the previous experimental results about the Cassie-Baxter-Wenzel wetting transition reported in the literature.

description: VoIP applications are emerging today as an important component in business and communication industry. In this paper, we address the intrusion detection and prevention in VoIP networks and describe how a conceptual solution based on the Bayes inference approach can be used to reinforce the existent security mechanisms. Our approach is based on network monitoring and analyzing of the VoIP-specific traffic. We give a detailed example on attack detection using the SIP signaling protocol.

description: An intriguing magneto-transport property is demonstrated by tight-binding lattice electrons with Rashba spin-orbit coupling (SOC) in a magnetic field. With the flux strength $ϕ={2π/N}$ ($N$ is an integer) and the Zeeman splitting fixed, when increasing the Rashba SOC $λ$, the spin-Hall and charge-Hall conductances (SHC and CHC) undergo four-step evolutions: the SHC shows size-dependent resonances and jumps at three critical $λ_{c}$'s, and changes its sign at $λ_{c1}$ and $λ_{c3}$; while the CHC exhibits three quantum jumps by $-Ne^2/h$, $+2Ne^2/h$ and $-Ne^2/h$. Such four-step evolutions are also reflected in topological characters and spin polarizations of edge states of a cylindrical system, and are robust against weak disorder.

description: B-Physics anomalies have recently raised renewed interest in leptoquarks (LQ), predicted in several theoretical frameworks. Under simplifying but conservative assumptions, we show that the current limits from LHC searches together with the requirement to explain the observed value for $R_{D^{(*)}}$ constrain the $R_2$ leptoquark mass to be in the range of $800 \leq m_{R_2} \leq 1000$ GeV. We study the search for $R_2$ at the LHeC via its resonance in the $bτ$ final state by performing a cut-and-count analysis of the signal and the dominant Standard Model backgrounds. We find that the LHeC has an excellent discovery potential for $R_2$ even for couplings to the first generation as small as ${\cal O}(10^{-2})$.
