description: We develop the kinetic theory of point vortices in two-dimensional hydrodynamics and illustrate the main results of the theory with numerical simulations. We first consider the evolution of the system "as a whole" and show that the evolution of the vorticity profile is due to resonances between different orbits of the point vortices. The evolution stops when the profile of angular velocity becomes monotonic even if the system has not reached the statistical equilibrium state (Boltzmann distribution). In that case, the system remains blocked in a sort of metastable state with a non standard distribution. We also study the relaxation of a test vortex in a steady bath of field vortices. The relaxation of the test vortex is described by a Fokker-Planck equation involving a diffusion term and a drift term. The diffusion coefficient, which is proportional to the density of field vortices and inversely proportional to the shear, usually decreases rapidly with the distance. The drift is proportional to the gradient of the density profile of the field vortices and is connected to the diffusion coefficient by a generalized Einstein relation. We study the evolution of the tail of the distribution function of the test vortex and show that it has a front structure. We also study how the temporal auto-correlation function of the position of the test vortex decreases with time and find that it usually exhibits an algebraic behavior with an exponent that we compute analytically. We mention analogies with other systems with long-range interactions.

description: El Ni o Southern Oscillation (ENSO), and its potential response to anthropogenic climate change, has recently become a topic of great interest following the anomalously strong El Ni o events of the late 20th-early 21st centuries. Strong events such as these are associated with drought, flooding, and damages to ecosystems, human health, agriculture, and infrastructure in many parts of the world. Long-lived corals in the equatorial Pacific Ocean track ENSO-related sea surface temperature (SST) over time in the Sr/Ca and oxygen isotopic ratios (d18O) of their skeletons, and these multi-decadal to multi-century histories can be accessed at monthly resolution. SST anomalies can be reconstructed from well-dated subfossil corals, providing “windows” into past ENSO activity. Current ENSO trends can be assessed by comparing past (pre-industrial) and modern windows of variability. The 17th-18th centuries, within a period of cooler temperatures in the northern hemisphere (the so-called “Little Ice Age”), provide a climatologically interesting window, as previously published records from the central Pacific suggest high ENSO variability at this time. Here, we investigate central Pacific (CP) and eastern Pacific (EP) ENSO variability using new and published subfossil coral records from the 17th-18th centuries, and compare them to the 20th century, as well as to the “recent modern” interval of 1990-2010 CE. We find that in the EP, El Ni o variability has increased substantially since the 1600’s, particularly in the recent modern interval. This result contrasts with CP variability, which we find does not change substantially over the past 400 years. Our new Gal pagos coral records demonstrate that ENSO in the EP is intensifying, in line with model projections under anthropogenic forcing and with the limited instrumental record. Such amplification will likely intensify the global impacts of the ENSO system in a warming world.

description: Dynamics of dissipation of a local phonon distribution to the substrate is a key issue in friction between sliding surfaces as well as in boundary lubrication. We consider a model system consisting of an excited nano-particle which is weakly coupled with a substrate. Using three different methods we solve the dynamics of energy dissipation for different types of coupling between the nano-particle and the substrate, where different types of dimensionality and phonon densities of states were also considered for the substrate. In this paper, we present our analysis of transient properties of energy dissipation via phonon discharge in the microscopic level towards the substrate. Our theoretical analysis can be extended to treat realistic lubricant molecules or asperities, and also substrates with more complex densities of states. We found that the decay rate of the nano-particle phonons increases as the square of the interaction constant in the harmonic approximation.

description: Using a parameterisation of general self-adjoint boundary conditions in terms of Lagrange planes we propose a scheme for factorising the matrix Schroedinger operator and hence construct a Darboux transformation an interesting feature of which is that the matrix potential and boundary conditions are altered under the transformation. We present a solution of the inverse problem in the case of general boundary conditions using a Marchenko equation and discusss the specialisation to the case of graph with trivial compact part, ie. diagonal matrix potential.

description: The description of electron current through a splitting is a mathematical problem of electron transport in quantum networks. For quantum networks constructed on the interface of narrow-gap semiconductors the relevant scattering problem for the multi-dimensional Schoedinger equation may be substituted by the corresponding problem on a one-dimensional linear graph with proper selfadjoint boundary conditions at the nodes. However, realistic boundary conditions for splittings have not yet been derived. Here we consider some compact domain attached to a few semi-infinite lines as a model for a quantum network. An asymptotic formula for the scattering matrix for this object is derived in terms of the properties of the compact domain. This allows us to propose designs for devices for manipulating quantum current through a splitting.

description: We consider f(R) modified gravity theories in the metric variation formalism and attempt to reconstruct the function f(R) by demanding a background LCDM cosmology. In particular we impose the following requirements: a. A background cosmic history H(z) provided by the usual flat LCDM parametrization though the radiation (w_eff=1/3), matter (w_eff=0) and deSitter (w_eff=-1) eras. b. Matter and radiation dominate during the `matter' and `radiation' eras respectively i.e. Ω_m =1 when w_eff=0 and Ω_r=1 when w_eff=1/3. We have found that the cosmological dynamical system constrained to obey the LCDM cosmic history has four critical points in each era which correspondingly lead to four forms of f(R). One of them is the usual general relativistic form f(R)=R-2Λ. The other three forms in each era, reproduce the LCDM cosmic history but they do not satisfy requirement b. stated above. Only one of these forms (different from general relativity) is found to be an attractor of the dynamical cosmological evolution. It has (Ω_DE=1, Ω_r=0, Ω_m=0) throughout the evolution. Its phase space trajectory is numerically obtained.

Ixodes siamensis

description: Ixodes siamensis Kitaoka and Suzuki, 1983
 Ixodes siamensis was described from larvae collected on shrews and rodents in a montane rainforest at Doi Inthanon, northern Thailand. Larvae remain the only life history stage described (Guglielmone et al. 2014).
 The validity of this species is doubtful, with some authors treating it as a synonym of I. ovatus (Camicas et al. 1998; Kolonin 2009), but it is tentatively recognized by Guglielmone et al. (2009, 2014). There is thus a need to revise what is currently considered I. ovatus to determine whether I. siamensis is part of a species complex (Guglielmone et al. 2009).

description: The natural convection of incompressible fluid in a porous medium causes for some boundary conditions a strong non-uniqueness in the form of a continuous family of steady states. We are interested in the situation when these boundary conditions are violated. The resulting destruction of the family of steady states is studied via computer experiments based on a mimetic finite-difference approach. Convection in a rectangular enclosure is considered under different perturbations of boundary conditions (heat sources, infiltration). Two scenario of the family of equilibria are found: the transformation to a limit cycle and the formation of isolated convective patterns.

Equation of State of Nuclear Matter at high baryon density

Year: 2007
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: A central issue in the theory of astrophysical compact objects and heavy ion reactions at intermediate and relativistic energies is the Nuclear Equation of State (EoS). On one hand, the large and expanding set of experimental and observational data is expected to constrain the behaviour of the nuclear EoS, especially at density above saturation, where it is directly linked to fundamental processes which can occur in dense matter. On the other hand, theoretical predictions for the EoS at high density can be challenged by the phenomenological findings. In this topical review paper we present the many-body theory of nuclear matter as developed along different years and with different methods. Only nucleonic degrees of freedom are considered. We compare the different methods at formal level, as well as the final EoS calculated within each one of the considered many-body schemes. The outcome of this analysis should help in restricting the uncertainty of the theoretical predictions for the nuclear EoS.

Remarks on Duality Transformations and Generalized Stabilizer States

Publisher: name: arXiv
Year: 2007
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We consider the transformation of Hamilton operators under various sets of quantum operations acting simultaneously on all adjacent pairs of particles. We find mappings between Hamilton operators analogous to duality transformations as well as exact characterizations of ground states employing non-Hermitean eigenvalue equations and use this to motivate a generalization of the stabilizer formalism to non-Hermitean operators. The resulting class of states is larger than that of standard stabilizer states and allows for example for continuous variation of local entropies rather than the discrete values taken on stabilizer states and the exact description of certain ground states of Hamilton operators.

The analysis of the 4.8GHz data indicate weak wispy shell-like radio structure(s) which are at least partially non-thermal. The radio data is compatible with one or more young supernova remnants or perhaps the signature of large scale cluster shocks in this region induced by the violent action of the many massive stars in Cyg OB2.

Δέκα τύποι ραμμάτων (συνθετικά και απορροφήσιμα), τέσσερα πιο συνηθισμένα είδη τεχνικών συρραφής και οκτώ είδη αγκυρών που συχνά χρησιμοποιούνται στην χειρουργική ώμου δοκιμάστηκαν. Η εμβιομηχανική μελέτη έγινε με τη χρήση Οργάνου Μέτρησης Αντοχής Υλικών σε παρασκευάσματα στροφικού πετάλου και εγγύς βραχιονίου σφαγιασθέντων προβάτων. Φορτία και μετατόπιση καταγράφηκαν και η μέση των μεγίστων δύναμη εφελκυσμού όπως και η δυσκαμψία αυτών υπολογίστηκε. Το μέσο φορτίο αστοχίας και η δυσκαμψία ήταν υψηλότερη στα σύγχρονα συνθετικά ράμματα σε σύγκριση με τα αντίστοιχα απορροφήσιμα. Η ραφή τύπου Mαζικής Ρήξης Πετάλου (MCT) και η Τροποποιημένη ραφή τύπου Mason-Allen (MMA) είχαν υψηλότερο φορτίο αστοχίας όπως και δυσκαμψία σε σύγκριση με την απλή ραφή ή αυτήν τύπου mattress. Όμως δεν υπήρχε στατιστικά σημαντική διαφορά ανάμεσα στις δύο πρώτες. Οι μεταλλικές άγκυρες έχουν υψηλότερο φορτίο αστοχίας απ’ότι οι βιοαπορροφήσιμες και συχνά όλες αποτυγχάνουν στο eyelet-«μάτι» τους. Οι μεταλλικές άγκυρες με περασμένα σύγχρονα συνθετικά ράμματα θα αποτύχουν τελευταίες. Το επίπεδο τένοντα-ράμματος θα αποτύχει πρώτο χρησιμοποιώντας απλή ή mattress ραφές, ενώ βελτιώνεται με MCT ή MMA ραφές.
description: The purpose of our work was to assess load to failure of sutures, suturing techniques, and suture anchors used in rotator cuff surgery. Ten types of sutures (absorbable and non-absorbable), four types of suturing techniques and eight types of sutures anchors (bioabsorbale and metallic) commonly used in open and arthroscopic rotator cuff surgery were tested. The biomechanical study was performed using Materials Testing Machine in ex-vivo ovine humeral heads and rotator cuff tissue and load to failure and stiffness were assessed The mean load to failure and stiffness was higher in modern synthetic non-absorbable sutures. Massive cuff tear (MCT) and modified Mason-Allen (MMA) suturing techniques had higher failure strength and stiffness comparing to simple and mattress techniques but there was no substantial difference between them. Metallic suture anchors had higher failure strength comparing to bioabsorbable ones and often in either of them the eyelet fails first. Metallic anchors mounted with modern non-absorbable sutures will fail last. The tendon-suture level using simple and mattress technique will fail first, however, it can be improved with MCT or MMA techniques.

description: We investigate the possible types of coupling between ferroelectricity and magnetism for the zig-zag spin chain multiferroic LiCu2O2 compound. We construct a multi-order parameter phenomenological model for the material based on a group theoretical analysis. From our calculation we conclude that a coupling involving the inter-chain magnetic structure and ferroelectricity is necessary to understand the experimental results of Park et.al. Our proposed model is able to account for the electric polarization flop in the presence of an externally applied magnetic field. Furthermore, based on our theoretical model we can make specific selection rule predictions about electromagnon excitations present in the LiCu2O2 system. We also predict that the electromagnon peaks measured in an ac-conductivity measurement are field dependent.

Electron wavefunctions at crystal interfaces
Creators: name: Patitsas, Stathis Nikos
Publisher: name: University of British Columbia
Year: 2010

description: A one dimensional analysis of the boundary conditions of the electron energy eigenfunc-tion at a sharp interface between two crystals was made. An attempt to evaluate these conditions in terms of known band structure was made. It was concluded that this cannot be done in general. It was shown, however, that if the interface has the proper symmetry properties, the boundary conditions can be expressed in terms of only one unknown, energy-dependent parameter. It was concluded that setting this parameter equal to one gives boundary conditions which, though more general, are equivalent to the commonly used effective mass boundary conditions when they are applicable. It was concluded from numerical results for the transmission coefficient of the symmetric interface, that in general, these boundary conditions, which depend only on known band structure, do not give a good approximation to the exact answer. Since the energy dependence of the parameter mentioned above is described quite well qualitatively using the nearly free electron approximation or the tight-binding approximation, the applicability of any boundary conditions depending only on band structure can be predicted using these simple theories. The exact numerical results were calculated using the transfer matrix method. It was also concluded that the presence of symmetry in the interface either maximizes or minimizes the transmission coefficient. A tight-binding calculation showed that the transmission coefficient depends on an interface parameter which is independent of band structure. The transmission coefficient is maximized when this parameter is ignored. It was concluded that the effective mass equation is of little use when applied to this problem. Some transfer matrix results pertaining to the barrier and the superlattice were obtained.

description: In many situations, the decision maker observes items in sequence and needs to determine whether or not to retain a particular item immediately after it is observed. Any decision rule creates a set of items that are selected. We consider situations where the available information is the rank of a present observation relative to its predecessors. Certain ``natural'' selection rules are investigated. Theoretical results are presented pertaining to the evolution of the number of items selected, measures of their quality and the time it would take to amass a group of a given size.

description: In this paper we discuss a quantity that can be derived from the hadronic spectrum - the ratio between the color hyperfine splitting of a K meson and that of a Sigma baryon. It will be shown that within the constituent quark model this ratio depends only on the ratio of contact probabilities within the hadrons. We compute this ratio assuming several phenomenological potential models, and show that the best agreement with data is obtained from the Cornell potential - Coulomb + linear. Thus the analysis of color hyperfine interactions corroborat es the preference for the Cornell potential based on quarkonium spectra.

description: In this article, we take the point of view that the light scalar meson $a_0(980)$ is a conventional $q\bar{q}$ state, and calculate the coupling constants $g_{a_0ηπ^0}$ and $g_{a_0 η'π^0}$ with the light-cone QCD sum rules. The central value of the coupling constant $g_{a_0ηπ^0}$ is consistent with the one extracted from the radiative decay $ϕ(1020)\to a_0(980)γ\to ηπ^0 γ$. The central value and lower bound of the decay width $Γ_{a_{0}\to ηπ^0}=127^{+84}_{-48} \rm{MeV} $ are compatible with the experimental data of the total decay width $Γ_{a_0(980)}=(50-100) \rm{MeV}$ from the Particle Data Group with very model dependent estimation (the decay width can be much larger), while the upper bound is too large. We give possible explanation for the discrepancy between the theoretical calculation and experimental data.

What, then, is the role of data provenance, and how can this be conveyed?

At The National Library of Scotland, an in-house, mass-digitisation programme runs 14 hours and produces many thousands of images each day. As we produce data at scale, we need to ensure that our readers understand where the data they use has come from, what processes it has undergone, and why it exists in the first place. How to convey that information in an area that currently has few agreed standards, and how libraries can remain trusted sources of information when we are creating that information ourselves, is problematic.

This lightning talk will consider the importance of data provenance and discuss how The National Library of Scotland is seeking to contextualise its data collections as it establishes a new Digital Scholarship Service. Conveying structural, bibliographical and technical metadata, as well as rights information, for each digital object enables readers to piece together how data has been produced; in addition to this, by including further information about the reasoning behind why an item has been digitised, we are aiming for a level of transparency between library and reader which enables a clearer understanding of the library processes print items undergo when creating collections as data.

This ties in to the new responsibilities of libraries as we produce our own collections: with digitisation programmes creating not only OCRed text, but also additional data from scanners, software and digital production tools, transparency about our data creation processes become important. Enabling readers to contextualise the data creation process aligns libraries with the need for reproducible and authentic data, and ensures that we do not preclude some forms of research.

description: In an earlier paper, we obtained exact solutions of the Wheeler-DeWitt equation for the Lemaitre-Tolman-Bondi (LTB) model of gravitational collapse, employing a lattice regularization. In this paper, we derive Hawking radiation in non-marginally bound models from our exact solutions. We show that a non-vanishing energy function does not spoil the (approximate) Planck spectrum near the horizon. We can also reliably compute corrections to the Bogoliubov coefficient because our solutions are exact. The corrections are obtained by going beyond the near horizon region and are shown to introduce additional greybody factors, which modify the black body spectrum of radiation from the black hole.

description: This paper shows the existence of independent random matching of a large (continuum) population in both static and dynamic systems, which has been popular in the economics and genetics literatures. We construct a joint agent-probability space, and randomized mutation, partial matching and match-induced type-changing functions that satisfy appropriate independence conditions. The proofs are achieved via nonstandard analysis. The proof for the dynamic setting relies on a new Fubini-type theorem for an infinite product of Loeb transition probabilities, based on which a continuum of independent Markov chains is derived from random mutation, random partial matching and random type changing.

description: Η κινητικότητα του λεπτού εντέρου είναι μια παράμετρος η οποία θα μπορούσε να βοηθήσει στην εκτίμηση της κατάστασης του εντέρου. Η κινητικότητα αυτή μεταβάλλεται σε καταστάσεις ισχαιμίας του εντέρου. Θεωρώντας ότι η μεταβολή αυτή θα είναι ανάλογη της ισχαιμίας, σχεδιάστηκε το πείραμα αυτό με σκοπό την μελέτη της μεταβολής της εντερικής κινητικότητας. Σαν ερέθισμα για την πρόκληση σύσπασης του εντερικού τοιχώματος χρησιμοποιήθηκε ηλεκτρικό ρεύμα διαβαθμισμένης έντασης. Τα δεδομένα που καταγράφηκαν υποδεικνύουν ότι η μεταβολή της κινητικότητας του λεπτού εντέρου είναι ανάλογη της ισχαιμίας και ότι η μεταβολή αυτή και η καταγραφή της μπορεί να βοηθήσει στην εκτίμηση του χειρουργού για την βιωσιμότητα του εντέρου. Στην πειραματική αυτή εργασία χρησιμοποιήθηκαν 20 κόνικλοι οι οποίοι χωρίστηκαν σε δύο ομάδες με κριτήριο την ηλικία τους. Η πρώτη ομάδα περιελάμβανε κονίκλους άνηβους, ενώ η δεύτερη ενήλικες. Τα αποτελέσματα και των δύο ομάδων έδειξαν ότι υπάρχει συσχέτιση των τιμών της έντασης του ηλεκτρικού ρεύματος με τον βαθμό ισχαιμίας, και ότι είναι δυνατόν να εκτιμηθεί με τον τρόπο αυτό η βιωσιμότητα του εντέρου. Ένα άλλο ενδιαφέρον αποτέλεσμα είναι η διαφορά που παρουσιάστηκε μεταξύ των δύο ομάδων. Για την 1η ομάδα η ένταση του ρεύματος που χρειαζόταν να αντιδράσει το τοίχωμα, ήταν μικρότερη από αυτή της δεύτερης ομάδας, γεγονός που πιθανότατα σημαίνει καλύτερη κατάσταση του εντέρου παρ’ όλη την ισχαιμία. Πιστεύουμε ότι τα δεδομένα αυτά θα πρέπει να επιβεβαιωθούν με έρευνα βοηθώντας την κατανόηση και την αντιμετώπιση της πάθησης.
description: Gut motility is a parameter which is difficult to assess. In case of intestinal ischemia the motility is altered. This alteration can be useful in the assessment of the viability of the intestine. This led us to study gut motility and the alterations that happen in case of ischemia. The stimulus was electric current and the intestinal respond was checked visually. This experimental study was performed in 20 rabbits. The rabbits were divided in two groups. In the 1st group were the young animals (< 4 m. age), while in the 2nd were the adult rabbits. All the animals were operated and the motility of their intestine was assessed in normalcy and in intestinal ischemia. The results showed that there is a correlation between the degree of ischemia and the electrical current value, capable of producing a respond. This method seems to be more accurate than visual observation and may be used for the assessment of intestinal motility.

description: In this paper, we study localization and mass spectrum of various matter fields on a family of thick brane configurations in a pure geometric Weyl integrable 5-dimensional space time, a non-Riemannian modification of 5-dimensional Kaluza--Klein (KK) theory. We present the shape of the mass-independent potential of the corresponding Schrödinger problem and obtain the KK modes and mass spectrum, where a special coupling of spinors and scalars is considered for fermions. It is shown that, for a class of brane configurations, there exists a continuum gapless spectrum of KK modes with any $m^2>0$ for scalars, vectors and ones of left chiral and right chiral fermions. All of the corresponding massless modes are found to be normalizable on the branes. However, for a special of brane configuration, the corresponding effective Schrödinger equations have modified Pöschl-Teller potentials. These potentials suggest that there exist mass gap and a series of continuous spectrum starting at positive $m^2$. There are one bound state for spin one vectors, which is just the normalizable vector zero mode, and two bound KK modes for scalars. The total number of bound states for spin half fermions is determined by the coupling constant $η$. In the case of no coupling ($η=0$), there are no any localized fermion KK modes including zero modes for both left and right chiral fermions. For positive (negative) coupling constant, the number of bound states of right chiral fermions is one less (more) than that of left chiral fermions. In both cases ($η>0$ and $η<0$), only one of the zero modes for left chiral fermions and right chiral fermions is bound and normalizable.

description: Ixodes simplex Neumann, 1906
 Ixodes simplex is a bat tick with a very wide distribution. It has been reported from Africa, Europe, China, Japan, Taiwan, Australia, the Pacific Islands and New Guinea (Arthur 1965; Roberts 1970; Wilson 1970; Hoogstraal et al. 1972b). Records from continental Southeast Asia are relatively uncommon but it has been recorded from peninsular Malaysia, Thailand and Vietnam (Hoogstraal et al. 1972b; Petney and Keirans 1994; Kolonin 2003). Its hosts are predominantly microchiropteran bats, especially the genus Miniopterus which is the most commonly recorded genus, and in particular M. schreibersii, as well as members of the genera Myotis and Rhinolophus. Ixodes simplex has been recorded from sea level to 2,000 m, where it is found in bat caves (Kolonin 2009).
 The female and nymph are illustrated in Yamaguti et al. (1971).

description: Smilirhexia naranja McKamey, sp. n. urn:lsid:zoobank.org:act: F473B88C-4AF2-45CF-9F7D-964FBCDF7B3F Description of male. Length including forewings in repose 8.0 mm, width between humeral angles 4.6 mm. Color. Head yellow-orange. Pronotum yellow-orange dorsally and posteriorly, yellow laterally except with large lateral indentation at mid-length black. Forewing fuscous at coriaceous base and transversally at distal crossveins, cells tinted yellow basally, hyaline distally. Male terminalia (Figs 4-6): lateral plate distinct, long, lacking protuberances. Aedeagus narrow in anterior view, in lateral view Ushaped and widest at mid-length, anterior margin with many denticulae of increasing size ventrally; styles simple, distally recurved (Fig. 4), apex acute. Female. Unknown. Distribution. COSTA RICA: Puntarenas Prov.: Coto Brus, nr. San Vito, Estación Biológica Las Alturas, 8 o 57’N, 82 o 50’W. Material Examined. Holotype male, pinned, dissected, with labels “Est. Biol. Las Alturas, / 1500m., Coto Brus, Prov. / Puntarenas. Costa Rica, / F.

Deposited at the Instituto Nacional de Biodiversidad (INBio), Santo Domingo de Heredia, Costa Rica. Etymology. The species epithet is a Spanish adjective for orange, the predominant pronotal color of the species. Notes. In Costa Rica, most oaks occur in submontane and montane forests (1500- 3200m) (Kappelle et al. 1992). In the Cordillera de Talamanca, which contains the type locality, there are at least eight oak species, with at least three reported from Coto Brus itself: Quercus seemannii Liebm., Q. oocarpa Liebm., and Q. rapurahuensis Pittier ex Trel. (Giddy 2008), and another (Q. insignis M. Martens & Gal.) at 1300m on the trail to Las Alturas (Instituto Nacional de Biodiversidad 2008). In short, it is easily possible that this new treehopper genus, like others in the tribe, feeds on Quercus.

description: We investigate localized atomic matter waves in two-component Bose-Einstein condensates coupled by the two photon microwave field. Interestingly, the oscillations of localized atomic matter waves will gradually decay and finally become non-oscillating behavior even if existing coupling field. In particular, atom numbers occupied in two different hyperfine spin states will appear asymmetric occupations after some time evolution.
