description: Gravity modes are the best probes to infer the properties of the solar radiative zone that represents 98% of the Sun's total mass. It is usually assumed that high-frequency g modes give information about the structure of the solar interior whereas low-frequency g modes are more sensitive to the solar dynamics (the internal rotation). In this work, we develop a new methodology, based on the analysis of the almost constant separation of the dipole gravity modes, to introduce new constraints on the solar models. To validate this analysis procedure, several solar models -- including different physical processes and either old or new chemical abundances (from, respectively, Grevesse and Noels (Origin and evolution of the elements. Cambridge, England, 199, 15, 1993) and Asplund, Grevesse, and Sauval (Astron. Soc. Pac. CS, San Francisco, 36, 25, 2005)) -- have been compared to another model used as a reference. The analysis clearly shows that this methodology has enough sensitivity to distinguish between some of the models, in particular, between those with different compositions. The comparison of the models with the g-mode asymptotic signature detected in GOLF data favors the ones with old abundances. Therefore, the physics of the core -- through the analysis of the g-mode properties -- is in agreement with the results obtained in the previous studies based on the acoustic modes, which are mostly sensitive to more external layers of the Sun.

Design Strategies and Knowledge in Object-Oriented Programming: Effects of Experience

Publisher: name: arXiv
Year: 2006
Subjects: subject: Human-Computer Interaction (cs.HC)
subject: FOS: Computer and information sciences

description: An empirical study was conducted to analyse design strategies and knowledge used in object-oriented software design. Eight professional programmers experienced with procedural programming languages and either experienced or not experienced in object-oriented design strategies related to two central aspects of the object-oriented paradigm: (1) associating actions, i.e., execution steps, of a complex plan to different objects and revising a complex plan, and (2) defining simple plans at different levels in the class hierarchy. As regards the development of complex plans elements attached to different objects, our results show that, for beginners in OOP, the description of objects and the description of actions are not always integrated in an early design phase, particularly for the declarative problem whereas, for the programmers experienced in OOP, the description of objects and the description of actions tend to be integrated in their first drafts of solutions whichever the problem type. The analysis of design strategies reveal the use of different knowledge according to subjects' language experience: (1) schemas related to procedural languages; actions are organized in an execution order, or (2) schemas related to object-oriented languages; actions and objects are integrated, and actions are organised around objects.

These prices depend both on a set of games that are available for investing simultaneously and on a risk-free interest rate. In addition, we show a case where the mean-variance portfolio theory is inappropriate.

description: We present an efficient quantum algorithm for the exact evaluation of either the fully ferromagnetic or anti-ferromagnetic q-state Potts partition function Z for a family of graphs related to irreducible cyclic codes. This problem is related to the evaluation of the Jones and Tutte polynomials. We consider the connection between the weight enumerator polynomial from coding theory and Z and exploit the fact that there exists a quantum algorithm for efficiently estimating Gauss sums in order to obtain the weight enumerator for a certain class of linear codes. In this way we demonstrate that for a certain class of sparse graphs, which we call Irreducible Cyclic Cocycle Code (ICCC_ε) graphs, quantum computers provide a polynomial speed up in the difference between the number of edges and vertices of the graph, and an exponential speed up in q, over the best classical algorithms known to date.

description: By studying a modified (unbiased) quantum multibaker map, we were able to obtain a {\em finite} asymptotic quantum current without a classical analogue. This result suggests a general method for the design of {\em purely} quantum ratchets, and sheds light on the investigation of the mechanisms leading to net transport generation by breaking symmetries of quantum systems. Moreover, we propose the multibaker map as a resource to study directed transport phenomena in chaotic systems without bias. In fact, this is a paradigmatic model in classical and quantum chaos, but also in statistical mechanics.

Gas-phase CO in protoplanetary disks: a challenge for turbulent mixing

description: This is the first paper in a series where we study the influence of turbulent diffusion and advective transport on the chemical evolution of protoplanetary disks, using a 2D flared disk model and a 2D mixing gas-grain chemical code with surface reactions. A first interesting result concerns the abundance of gas-phase CO in the outer regions of protoplanetary disks. In this Letter we argue that the gas-phase CO concentration in the disk regions, where the temperature is lower than $\sim25$ K, can be significantly enhanced due to the combined effect of vertical and radial mixing. This finding has a potential implication for the current observational data on the DM~Tau disk chemistry.

description: The objective of this research is to analyse the ways members of open-source software communities participate in design. In particular we focus on how users of an Open Source (OS) programming language (Python) participate in adding new functionalities to the language. Indeed, in the OS communities, users are highly skilled in computer sciences; they do not correspond to the common representation of end-users and can potentially participate to the design process. Our study characterizes the Python galaxy and analyses a formal process to introduce new functionalities to the language called Python Enhancement Proposal (PEP) from the idea of language evolution to the PEP implementation. The analysis of a particular pushed-by-users PEP from one application domain community (financial), shows: that the design process is distributed and specialized between online and physical interactions spaces; and there are some cross participants between users and developers communities which may reveal boundary spanners roles.

description: We review some decays that require knowledge of the decay constants of $0^{+}$ heavy-light mesons. We compute the decay constants of P-wave heavy-light mesons from unquenched lattice QCD, with two degenerate flavours of sea quarks, at a single lattice spacing. The lightest sea quark mass used in the calculation is a third of the strange quark mass. For the charm-strange meson we obtain the decay constant: $f_{D_{s 0^+}} = 340(110)$ MeV using our normalisation conventions. We obtain the $f_{P_s}^{static}$ (static-strange P-wave) decay constant as $302(39)$ MeV.

Testing the Disk Regulation Paradigm with Spitzer Observations. II. A Clear Signature of Star-Disk Interaction in NGC 2264 and the Orion Nebula Cluster

Year: 2007

description: Observations of PMS star rotation periods reveal slow rotators in young clusters of various ages, indicating that angular momentum is somehow removed from these rotating masses. The mechanism by which spin-up is regulated as young stars contract has been one of the longest-standing problems in star formation. Attempts to observationally confirm the prevailing theory that magnetic interaction between the star and its circumstellar disk regulates these rotation periods have produced mixed results. In this paper, we use the unprecedented disk identification capability of the Spitzer Space Telescope to test the star-disk interaction paradigm in two young clusters, NGC 2264 and the Orion Nebula Cluster (ONC). We show that once mass effects and sensitivity biases are removed, a clear increase in the disk fraction with period can be observed in both clusters across the entire period range populated by cluster members. We also show that the long-period peak (P $\sim$8 days) of the bimodal distribution observed for high-mass stars in the ONC is dominated by a population of stars possessing a disk, while the short-period peak (P $\sim$2 days) is dominated by a population of stars without a disk. Our results represent the strongest evidence to date that star-disk interaction regulates the angular momentum of these young stars. This study will make possible quantitative comparisons between the observed period distributions of stars with and without a disk and numerical models of the angular momentum evolution of young stars.

Mechanism of energization of transhydrogenase in Escherichia coli membranes
Creators: name: Chang, David Yeun Bin
Publisher: name: University of British Columbia
Year: 2010

description: Low concentrations of the group IIA metals Mg²⁺, Ca²⁺, and Ba²⁺ stimulated energy-independent transhydrogenase activity. High concentrations of Mg²⁺ inhibited this activity. Transhydrogenase requires Mg²⁺-complexed NADP(H) rather than free NADP(H) as its substrate. High concentrations of Mg2+, however, may change the conformation of the enzyme to inhibit its enzymatic reaction by binding directly to the NADP(H) site. Upon transhydrogenation between NADPH and 3-acetylpyridine dinucleotide, E. coli pyridine nucleotide transhydrogenase can establish a proton gradient across the cell membrane. The primary component of the proton gradient for energization of transhydrogenase was found to be the pH gradient and not the membrane potential. A similar conclusion was drawn for the ATP-driven transhydrogenase reactions. In strains of E. coli that harbored plasmids to give the cells elevated levels of transhydrogenase, it was found that uncouplers stimulated the aerobic-driven transhydrogenase reaction. This is a chemiosmotic anomaly and is in contrast to the non-plasmid containing parent strains where uncouplers inhibited the activity. Further investigation revealed that the plasmid strains contained a much lower NADH oxidase activity than the non-plasmid strains and that neither KCN nor QNO can inhibit the aerobic-dependent activity in both types of strains even though they were effective in blocking the respiratory chain. These effects prompted us to inquire whether the anomaly was due to differences in the respiratory chain, but no differences were found between the NADH dehydrogenase activities, quinone and cytochrome contents of the plasmid and non-plasmid strains. The bacterial cells with amplified transhydrogenases induce extra intracellular tubular membrane structures to accomodate the extra proteins (Clark, D.M., Pyridine Nucleotide Transhydrogenase, PhD thesis, University of British Columbia, 1986). Separation of the E. coli membrane vesicles on a shallow sucrose gradient, however, did not reveal any differences between the vesicles of the plasmid and non-plasmid strains. Therefore, it seems unlikely that the anomaly is due to the plasmid strains performing a unique form of energization on these induced structures. Finally, it was established by SDS-PAGE and Western blot using anti-transhydrogenase antisera that the plasmid strains express a much higher level of transhydrogenase enzymes in their cell membranes than do the non-plasmid strains.

description: The recent detection of $γ$-rays with energy up to 10 TeV from dense regions surrounding some Supernova Remnants (SNR) provides strong, though still not conclusive, evidence that the nucleonic component of galactic Cosmic Rays is accelerated in the supernova outflows. Neutrino telescopes could further support the validity of such scenario by detecting neutrinos coming from the same regions. We re-evaluate the TeV range neutrino-photon flux ratio to be expected from pion decay, finding small differences respect to previous derivations. We apply our results and the recent HESS measurements of the very high energy $γ$-ray flux from the molecular cloud complex in the Galactic Centre, to estimate the neutrino flux from that region discussing the detectability perspectives for Mediterranean Neutrino Telescopes. We also discuss under which conditions neutron decay may give rise to a significant TeV antineutrino flux from a SNR embedded in Molecular Cloud complexes.

Detecting charge noise with a Josephson junction: A problem of thermal escape in presence of non-Gaussian fluctuations

description: Motivated by several experimental activities to detect charge noise produced by a mesoscopic conductor with a Josephson junction as on-chip detector, the switching rate out of its zero-voltage state is studied. This process is related to the fundamental problem of thermal escape in presence of non-Gaussian fluctuations. In the relevant case of weak higher than second order cumulants, an effective Fokker-Planck equation is derived, which is then used to obtain an explicit expression for the escape rate. Specific results for the rate asymmetry due to the third moment of current noise allow to analyse experimental data and to optimize detection circuits.

description: We investigate the Kaluza-Klein braneworld cosmology from the point of view of observers on the brane. We first generalize the Shiromizu-Maeda-Sasaki (SMS) equations to higher dimensions. As an application, we study a (4+n)-dimensional brane with n dimensions compactified on the brane, in a (5+n)-dimensional bulk. By assuming that the size of the internal space is static, that the bulk energy-momentum tensor can be neglected, we determine the effect of the bulk geometry on the Kaluza-Klein braneworld. Then we derive the effective Friedmann equation on the brane. It turns out that the Friedmann equation explicitly depends on the equation of state, in contrast to the braneworld in a 5-dimensional bulk spacetime. In particular, in a radiation-dominated era, the effective Newton constant depends on the scale factor logarithmically. If we include a pressureless matter on the brane, this dependence disappears after the radiation-matter equality. This may be interpreted as stabilization of the Newton constant by the matter on the brane. Our findings imply that the Kaluza-Klein braneworld cosmology is quite different from the conventional Kaluza-Klein cosmology even at low energy.

description: Two-jet event shape distributions, traditionally studied in the language of perturbative QCD, can be described naturally in soft-collinear effective theory. In this language, we demonstrate factorization of event shape distributions into perturbatively-calculable hard and jet functions and nonperturbative soft functions, and show how the latter contribute universal shifts to the mean values of various event shape distributions. Violations of universality in shifts of higher moments can give information on correlations of energy flow in soft radiation.

description: All four giant planets in the Solar system possess irregular satellites, characterized by large, highly eccentric and/or inclined orbits that are distinct from the nearly circular, uninclined orbits of the regular satellites. This difference can be traced directly to different modes of formation. Whereas the regular satellites grew by accretion within circumplanetary disks the irregular satellites were captured from initially heliocentric orbits at an early epoch. Recently, powerful survey observations have greatly increased the number of known irregular satellites, permitting a fresh look at the group properties of these objects and motivating a re-examination of the mechanisms of capture. None of the suggested mechanisms, including gas-drag, pull-down, and three-body capture, convincingly fit the group characteristics of the irregular satellites. The sources of the satellites also remain unidentified.

Protecting Property Through Tort: The Implications of Using Tort Law to Protect ‘Property Interests’ in English Common Law
Creators: name: Ball, Victoria L.
Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: This thesis is concerned with the protection of property interests in English common law through the law of torts. Specifically, it considers conversion, trespass to goods, trespass to land, private nuisance, and negligence (as far as it relates to property damage). The overarching questions explored, are: What are the implications of relying on tortious mechanisms to protect property interests?; and, If there are implications, how can these be rectified? These questions stem from the fact that English common law lacks any true proprietary action, in the sense of an action that is proprietary in both substance and form. My approach in this thesis is to use the oft-quoted criticism by Tony Weir of the chattel torts and the common law’s lack of a bespoke proprietary protective mechanism as a starting point for analysing the property torts. The analytical approach taken in this thesis focuses on the underlying role of tort law and the implication of having an action classified as tortious, as both a problem, and a possible solution. It argues that, because the actions are classified and thought of as tortious mechanisms, the underlying view of tort law (as, for example, based on a loss-based model) has implications for how these actions develop through the case law. These decisions often move the actions away from their property roots and ignore the importance to property law that these actions have. The tortious nature of these actions also has implications for how well these actions remedy interferences with property. My solution in this thesis is that greater recognition needs to be given to the special place these actions have, as they have a unique role spanning both property and tort law. If this is done, and in conjunction we think of tort law in a way which respects the underlying rights that tort law focuses on, property can be better respected and protected by these actions.

description: We assume that the noncommutativity starts to be visible continuously from a scale $Λ_{NC}$. According to this assumption, a two-loop effective action is derived for noncommutative $ϕ^{4}$ and $ϕ^{3}$ theories from a Wilsonian point of view. We show that these effective theories are free of UV/IR mixing phenomena. We also investigate the positivity constraint on coefficients of higher dimension operators present in the effective theory. This constraint makes the low energy theory to be UV completion of a full theory. Finally, we discuss noncommutativity and extra dimensions. In our effective theories formulated on noncommutative extra dimensions, if the campactification scale $Λ_{c}$ is less than the scale $Λ_{NC}$, the theory will not suffer from UV/IR mixing.

description: We study the relation between the hessian matrix of the riemannian Reggae action on a 4-simplex and linearized quantum gravity. We give an explicit formula for the hessian as a function of the geometry, and show that it has a single zero mode. We then use a 3d lattice model to show that (i) the zero mode is a remnant of the continuum diffeomorphism invariance, and (ii) we recover the complete free graviton propagator in the continuum limit. The results help clarify the structure of the boundary state needed in the recent calculations of the graviton propagator in loop quantum gravity, and in particular its role in fixing the gauge.

Mussel culture in British Columbia : the influence of salmon farms on mussel growth and biochemical composition
Creators: name: Taylor, Barbara Elan
Publisher: name: University of British Columbia
Year: 2010

description: To realise the potential for mussel culture in British Columbia, mariculture research must identify specific environments and suitable locations which promote maximum growth in mussels. The present study investigates the possible advantages, through nutritional enrichment, of salmon farms as sites for mussel culture. Mussels were cultured at different distances around two salmon farms on the east coast of Vancouver Island (Departure Bay and Genoa Bay). Three parameters of mussel growth: condition index, carbohydrate content, and crude protein content were monitored at 3-6 wk intervals from September 1988 to August 1989. Distinct seasonal differences in growth were observed, but distance from the farm did not substantially influence mussel growth. Adult mortality and larval settlement were similarly unaffected. Contrary to prediction, the farms did not increase available food for mussels. Measures of seston and chlorophyll concentration, made concurrently with the mussel collections, indicated that neither a direct contribution of nutrients in the form of feed and fish faeces, nor an indirect contribution of waste ammonia to augment phytoplankton production, occurred. This was despite currents flowing, at least part of the time, in such a direction as to transport potential nutrients from the farms to the mussels.

description: Annotating NGS sequences by assigning taxa labels is a key component for the majority of metagenomic studies, and is often a prerequisite in effectively assessing biodiversity in a given environment. In this work we introduce k-taxatree, an alignment-free machine learning method that enables robust assignment of taxonomic labels to short reads, utilizing a multi-label Random Forest approach as the underlying model. We demonstrate the effectiveness of the method by applying it to data from the V4 hypervariable region of 16S rRNA reads, retrieved from the Earth Microbiome Project, displaying accuracy scores over 95% in the validation set. The workflow has been fully developed in R and is freely available at https://github.com/BiodataAnalysisGroup/k-taxatree.
Weighted complex projective 2-designs from bases: optimal state determination by orthogonal measurements

description: We introduce the problem of constructing weighted complex projective 2-designs from the union of a family of orthonormal bases. If the weight remains constant across elements of the same basis, then such designs can be interpreted as generalizations of complete sets of mutually unbiased bases, being equivalent whenever the design is composed of d+1 bases in dimension d. We show that, for the purpose of quantum state determination, these designs specify an optimal collection of orthogonal measurements. Using highly nonlinear functions on abelian groups, we construct explicit examples from d+2 orthonormal bases whenever d+1 is a prime power, covering dimensions d=6, 10, and 12, for example, where no complete sets of mutually unbiased bases have thus far been found.

description: In this paper we study the Neumann system, which describes the harmonic oscillator (of arbitrary dimension) constrained to the sphere. In particular we will consider the confluent case where two eigenvalues of the potential coincide, which implies that the system has S^{1} symmetry. We will prove complete algebraic integrability of confluent Neumann system and show that its flow can be linearized on the generalized Jacobian torus of some singular algebraic curve. The symplectic reduction of S^{1} action will be described and we will show that the general Rosochatius system is a symplectic quotient of the confluent Neumann system, where all the eigenvalues of the potential are double. This will give a new mechanical interpretation of the Rosochatius system.

Transition from AdS universe to DS universe in the BPP model

description: It can be shown that in the BPP model the smooth phase transition from the asymptotically decelerated AdS universe to the asymptotically accelerated DS universe is possible by solving the modified semiclassical equations of motion. This transition comes from noncommutative Poisson algebra, which gives the constant curvature scalars asymptotically. The decelerated expansion of the early universe is due to the negative energy density with the negative pressure induced by quantum back reaction, and the accelerated late-time universe comes from the positive energy and the negative pressure which behave like dark energy source in recent cosmological models.

description: This paper introduces a new program to find high-redshift radio galaxies in the southern hemisphere through ultra-steep spectrum (USS) selection. We define a sample of 234 USS radio sources with spectral indices alpha_408^843 < -1.0 and flux densities S_408 > 200 mJy in a region of 0.35 sr, chosen by cross-correlating the revised 408 MHz Molonglo Reference Catalogue, the 843 MHz Sydney University Molonglo Sky Survey and the 1400 MHz NRAO VLA Sky Survey in the overlap region -40 deg < delta < -30 deg. We present Australia Telescope Compact Array (ATCA) high-resolution 1384 and 2368 MHz radio data for each source, which we use to analyse the morphological, spectral index and polarization properties of our sample. We find that 85 per cent of the sources have observed-frame spectral energy distributions that are straight over the frequency range 408-2368 MHz, and that, on average, sources with smaller angular sizes have slightly steeper spectral indices and lower fractional linear polarization. Fractional polarization is anti-correlated with flux density at both 1400 and 2368 MHz. We also use the ATCA data to determine observed-frame Faraday rotation measures for half of the sample.

Slow evolution of elliptical galaxies induced by dynamical friction III. Role of density concentration and pressure anisotropy
Creators: name: Arena, S. E.

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: In this paper we study the infall, by dynamical friction, of rigid "satellites" taken in a variety of initial configurations and models. We thus measure how dynamical friction depends on the density concentration and on the pressure anisotropy of the host galaxy and, separately, the response of the galaxy during the process. The investigation is carried out by using a numerical laboratory set up in previous papers of this series. We find that the pressure anisotropy present in the host galaxy has little effect on dynamical friction. Instead, the shape of the galaxy density profile is very important. The classical idealized description appears to be applicable to galaxy models characterized by a small density gradient but not to concentrated models. In contrast to the behavior found in small density gradient models, the orbits of satellites captured in concentrated models are not circularized by dynamical friction. The induced evolution in the host galaxy reflects the initial conditions adopted for the captured satellite. Satellites spiraling in on quasi-circular orbits tend to modify the pressure tensor of the host galaxy in the tangential direction and the galaxy shape from spherical to oblate, while satellites captured along quasi-radial orbits tend to induce pressure anisotropy in the radial direction and to generate a prolate shape. This result suggests that the shape of early-type galaxies may result from occasional mergers rather than being directly related to the effectiveness of the radial-orbit instability during the process of formation via collisionless collapse, as often argued in the past.

description: Warped product CR-submanifolds in Kaehlerian manifolds were intensively studied only since 2001 after the impulse given by B.Y. Chen. Immediately after, another line of research, similar to that concerning Sasakian geometry as the odd dimensional version of Kaehlerian geometry, was developed, namely warped product contact CR-submanifolds in Sasakian manifolds. In this note we proved that there exists no proper doubly warped product contact CR-submanifolds in trans-Sasakian manifolds.

description: We constructed a dilution-refrigerator (DR) based ultra-low temperature scanning tunneling microscope (ULT-STM) which works at temperatures down to 30 mK, in magnetic fields up to 6 T and in ultrahigh vacuum (UHV). Besides these extreme operation conditions, this STM has several unique features not available in other DR based ULT-STMs. One can load STM tips as well as samples with clean surfaces prepared in a UHV environment to an STM head keeping low temperature and UHV conditions. After then, the system can be cooled back to near the base temperature within 3 hours. Due to these capabilities, it has a variety of applications not only for cleavable materials but also for almost all conducting materials. The present ULT-STM has also an exceptionally high stability in the presence of magnetic field and even during field sweep. We describe details of its design, performance and applications for low temperature physics.
