description: Refractory high entropy alloys (RHEA) have been proven to have excellent mechanical properties with a potential use as protective thin films. However, the combination of high hardness with low friction and wear is a major challenge in the design of self lubricating RHEA films. In this study, we show that designing of NbMoWTa/Ag multilayered films give a remarkable reduction in friction and at same time maintain high hardness. Interestingly, it's found that the bcc superlattice dominates in both layers and the interfaces are highly coherent when the individual layer thickness h is reduced below 10 nm. The film properties are then strongly dependent on h ranging from 100 to 2.5 nm, and the most promising properties are obtained when the interface structure transforms from incoherent to coherent ones. Specially, the multilayer with h = 2.5 nm exhibits superior tribological performance over monolithic NbMoWTa, due to the significant coherent strengthening along with the self-lubricating ability in the multilayer. This tailored phase transition and coherent structure between matrix and lubrication phases can also provide an optimal wear rate-coefficient of friction (COF) combination, which is higher than most of the Ag containing self lubricating films. The current work might open a new route towards the development of innovative self lubricating RHEA films with excellent tribological properties in general.

description: The aim of this article is to nuance and problematize how holiday travels are actively used in the identity constructions of the individual when identities are both multiple and perpetually changeable. On the basis of a number of qualitative surveys, central elements of the holiday travel and the concept of travel career as identity constructing are discussed. This identity construction is negotiated and staged in various social contexts, e.g. social media.

description: We have developed a semi-empirical simulation of the extragalactic radio continuum sky suitable for aiding the design of next generation radio interferometers such as the Square Kilometre Array (SKA). The emphasis is on modelling the large-scale cosmological distribution of radio sources rather than the internal details of individual galaxies. Here we provide a description of the simulation to accompany the online release of a catalogue of 320 million simulated radio sources. The simulation covers 20x20 deg^2 - a plausible upper limit to the instantaneous field of view attainable with future (e.g. SKA) aperture array technologies - out to redshift z=20, and down to flux density limits of 10 nJy at 151, 610 MHz, 1.4, 4.86 and 18 GHz. Five distinct source types are included: radio-quiet AGN, radio-loud AGN of the FRI and FRII structural classes, and star-forming galaxies, the latter split into populations of quiescent and starbursting galaxies. In our semi-empirical approach, the simulated sources are drawn from observed (or extrapolated) luminosity functions and grafted onto an underlying dark matter density field with biases which reflect their measured large-scale clustering. A numerical Press-Schechter-style filtering of the density field is used to identify and populate clusters of galaxies. Radio source structures are built from point source and elliptical sub-components, and for FRI and FRII sources an orientation-based unification and beaming model is used to partition flux between the core and extended lobes and hotspots. The simulation output can be post-processed to achieve more complete agreement with observational data in the years ahead, with the aim of using these 'idealised skies' in telescope simulators to optimise the design of the SKA itself (abridged).

description: We investigate the ability of algorithms developed for reverse engineering of transcriptional regulatory networks to reconstruct metabolic networks from high-throughput metabolite profiling data. For this, we generate synthetic metabolic profiles for benchmarking purposes based on a well-established model for red blood cell metabolism. A variety of data sets is generated, accounting for different properties of real metabolic networks, such as experimental noise, metabolite correlations, and temporal dynamics. These data sets are made available online. We apply ARACNE, a mainstream transcriptional networks reverse engineering algorithm, to these data sets and observe performance comparable to that obtained in the transcriptional domain, for which the algorithm was originally designed.

Self-regulated gravitational accretion in protostellar discs

description: We present a numerical model for the evolution of a protostellar disc that has formed self-consistently from the collapse of a molecular cloud core. The global evolution of the disc is followed for several million years after its formation. The capture of a wide range of spatial and temporal scales is made possible by use of the thin-disc approximation. We focus on the role of gravitational torques in transporting mass inward and angular momentum outward during different evolutionary phases of a protostellar disc with disc-to-star mass ratio of order 0.1. In the early phase, when the infall of matter from the surrounding envelope is substantial, mass is transported inward by the gravitational torques from spiral arms that are a manifestation of the envelope-induced gravitational instability in the disc. In the late phase, when the gas reservoir of the envelope is depleted, the distinct spiral structure is replaced by ongoing irregular nonaxisymmetric density perturbations. The amplitude of these density perturbations decreases with time, though this process is moderated by swing amplification aided by the existence of the disc's sharp outer edge. Our global modelling of the protostellar disc reveals that there is typically a residual nonzero gravitational torque from these density perturbations, i.e. their effects do not exactly cancel out in each region. In particular, the net gravitational torque in the inner disc tends to be negative during first several million years of the evolution, while the outer disc has a net positive gravitational torque. Our global model of a self-consistently formed disc shows that it is also self-regulated in the late phase, so that it is near the Toomre stability limit, with a near-uniform Toomre parameter Q\approx 1.5-2.0.

description: We report a demonstration of quantum key distribution (QKD) at GHz clock rates with InGaAs avalanche photodiodes (APDs) operating in a self-differencing mode. Such a mode of operation allows detection of extremely weak avalanches so that the detector afterpulse noise is sufficiently suppressed. The system is characterized by a secure bit rate of 2.37 Mbps at 5.6 km and 27.9 kbps at 65.5 km when the fiber dispersion is not compensated. After compensating the fiber dispersion, the QKD distance is extended to 101 km, resulting in a secure key rate of 2.88 kbps. Our results suggest that InGaAs APDs are very well suited to GHz QKD applications.

description: This paper studies the American perception of a lack of modernity in the postcolonial world. As usual, the lack of modernity allows for an idealized, romanticized vision of a simpler life without the ugliness of modern, Western life. A large aspect of Theroux’s thesis concerns the need for Africa to “return” to its “traditional” ways, as a simple land, and cast-off the failed attempt at colonial modernization enforced by the Europeans. As a travelogue, Theroux is also a tourist. Therefore, this work returns to the typical motif of the search for authenticity. Here I investigate Theroux’s approach to “finding” the real Africa as well as how his Africa is shaped by the experience he wants to find.

description: We use G-band and Ca II H image sequences from the Dutch Open Telescope (DOT) to study magnetic elements that appear as bright points in internetwork parts of the quiet solar photosphere and chromosphere. We find that many of these bright points appear recurrently with varying intensity and horizontal motion within longer-lived magnetic patches. We develop an algorithm for detection of the patches and find that all patches identified last much longer than the granulation. The patches outline cell patterns on mesogranular scales, indicating that magnetic flux tubes are advected by granular flows to mesogranular boundaries. Statistical analysis of the emergence and disappearance of the patches points to an average patch lifetime as long as 530+-50 min (about nine hours), which suggests that the magnetic elements constituting strong internetwork fields are not generated by a local turbulent dynamo.

description: Excerpts from the report: Water is becoming one of the Nation's most limiting resources. In irrigation for agriculture, conveyance losses and low application efficiencies of water represent the principal source of waste. About one-third of all water diverted for irrigation is lost from point of diversion to the farm. Another third is lost through deep percolation and runoff during application. This leaves one-third of the water diverted for irrigation available for plant growth and land conditioning. Both conveyance and application efficiencies of irrigation water can be greatly improved. Conveyance losses are easier to control, as canal management is usually in the hands of trained people. Watertight conveyance structures almost completely eliminated losses. Closed underground conduits are more efficient than open channels, but in most instances conduits are more expensive to construct than channels. Linings also help to control weeds and indirectly contribute to the solution of the drainage problem.

description: The world of James Herriot has expanded far beyond its British beginnings. The stories of this Yorkshire veterinarian and his work in the fictitious town of Darrowby, have reached around the globe. His works have been translated into dozens of languages and read in numerous countries. Despite (or perhaps because of) his popularity, there has been little critical examination of Herriot’s literary corpus. With a handful of exceptions, the Academy has largely turned a blind eye to his efforts. This essay suggests that we reread this popular author and explore the possibility that when we encounter the stories of life in the Yorkshire dales, we are in fact, encountering an important work of travel literature. Following a brief examination of his life, this essay focuses on themes in Herriot’s books that share much in common with other works of travel writing.

description: I discuss the spherically symmetric but inhomogeneous Lemaitre-Tolman- Bondi (LTB) metric, which provides an exact toy model for an inhomogeneous universe. Since we observe light rays from the past light cone, not the expansion of the universe, spatial variation in matter density and Hubble rate can have the same effect on redshift as acceleration in a perfectly homogeneous universe. As a consequence, a simple spatial variation in the Hubble rate can account for the distant supernova data in a dust universe without any dark energy. I also review various attempts towards a semirealistic description of the universe based on the LTB model.

The Hammock and the Colonial Journey of Conquest

description: The article considers the colonial meaning of the hammock. The conversion of the hammock from a stationary apparatus of leisure into that of a mobile train powered by human energy became identified with a symbol of British colonialism. But the introduction of the hammock was not accepted by the people hook, line and sinker; hence it was trailed by accounts of strong resistance and subsequent British policy of enforcement. The fear of the Hammock, carrying the White man on the hammock over a long distance became part of the colonial situation and its societal structure. The article includes a number of contemporary sources to throw light on this understanding of the hammock as not just a means of travel, but also of suppression.

description: In the 18th century, the fastest passage between Europe and the Indian Ocean was by way of Syria and Iraq. Travellers were faced with the choice between a number of routes across the desert and along the rivers, each with advantages and disadvantages in terms of price, time and security. This article discusses the choices made by a selection of European mid-18th-century travellers utilising perspectives from New institutional economics, arguing that their decisions must be interpreted in light of the their status as outsiders and the socio-economic structure of the societies they moved through.

description: We use a semianalytic galaxy catalogue constructed from the Millennium Simulation to study the satellites of isolated galaxies in the LCDM cosmogony. This sample (~80,000$ bright primaries, surrounded by ~178,000 satellites) allows the characterization, with minimal statistical uncertainty, of the dynamical properties of satellite/primary galaxy systems in a LCDM universe. We find that, overall, the satellite population traces the dark matter rather well: its spatial distribution and kinematics may be approximated by an NFW profile with a mildly anisotropic velocity distribution. Their spatial distribution is also mildly anisotropic, with a well-defined ``anti-Holmberg'' effect that reflects the misalignment between the major axis and angular momentum of the host halo. The isolation criteria for our primaries picks not only galaxies in sparse environments, but also a number of primaries at the centre of ''fossil'' groups. We find that the abundance and luminosity function of these unusual systems are in reasonable agreement with the few available observational constraints. We recover the expected L_{host} σ_{sat}^3 relation for LCDM models for truly-isolated primaries. Less strict primary selection, however, leads to substantial modification of the scaling relation. Our analysis also highlights a number of difficulties afflicting studies that rely on blind stacking of satellite systems to constrain the mean halo mass of the primary galaxies.

The Parthians between Rome and China

description: Following the expansion westwards of the Chinese Han Empire at the end of the 1st century AD the Parthian kingdom entered China’s political horizon. Gan Ying, a Chinese envoy was at the head of a diplomatic mission charged with establishing direct contacts and business relationships with the Roman Empire, the final destination for most of the goods they were exporting to the West. Gan Ying was able to reach Arsacid-controlled south Mesopotamia. Although very close to the Roman territory he did not manage to go further and accomplish his task. The Parthian leaders, well aware of the commercial role they played between Rome and China, dissuaded him from trying to proceed. This largely unknown but extremely interesting episode in the ancient history of Asia provides direct evidence concerning the political and commercial role of Parthia, Rome’s fierce enemy, in central Asia and along the Silk Route.

Arthur Conan Doyle’s Quest Journey to The Land of Mist
Creators: name: Christensen, Jørgen Riber
Publisher: name: Akademisk kvarter | Academic Quarter
Year: 2012

description: Arthur Conan Doyle employed the quest narrative structure in his Professor Challenger novels and short stories. The themes that were embodied in the journey were imperialism, positivist science, the male role, evolution, degeneration and atavism. However, in the last of this cycle, The Land of Mist (1926) the Victorian quest romance does not go to a lost, prehistoric world in the Amazonas. It takes on a surprising form as now the journey is to the realm of the dead. This destination can be regarded as a result of Doyle’s deep interest in spiritualism, but the article will seek to explain this in the context of its contemporary epistemology. It is the hypothesis of the article that doubts and problems of faith, both religious and ideological, could not be answered in any other way than by converting the narratological device of the quest journey into a statement of faith. The double world-view and its narratological consequences will be explained by the article through its use of Michel Foucault’s concept of the episteme.

description: Non-Hermitian materials can not only exhibit exotic energy band structures but also an anomalous velocity induced by non-Hermitian anomalous Berry connection as predicted by the semiclassical equations of motion for Bloch electrons. However, it is not clear how the modified semiclassical dynamics modifies transport phenomena. Here, we theoretically demonstrate the emergence of anomalous oscillations driven by either an external dc or ac electric field, which arise from non-Hermitian anomalous Berry connection. Moreover, it is a well-known fact that geometric structures of electric wave functions can only affect the Hall conductivity. However, we are surprised to find a non-Hermitian anomalous Berry connection induced anomalous linear longitudinal conductivity independent of the scattering time. We also show the emergence of a second-order nonlinear longitudinal conductivity induced by non-Hermitian anomalous Berry connection, violating a well-known fact of its absence in a Hermitian system with symmetric energy spectra. These anomalous phenomena are illustrated in a pseudo-Hermitian system with large non-Hermitian anomalous Berry connection. Finally, we propose a practical scheme to realize the anomalous oscillations in an optical system.

description: In superconductors, electrons with spin ${s=1/2}$ form Cooper pairs whose spin structure is usually singlet (${S=0}$) or triplet (${S=1}$). When the electronic structure near the Fermi level is characterized by fermions with angular momentum ${j=3/2}$ due to strong spin-orbit interactions, novel pairing states such as even-parity quintet (${J=2}$) and odd-parity septet (${J=3}$) states become allowed. Prime candidates for such exotic states are half-Heusler superconductors, which exhibit unconventional superconducting properties, but their pairing nature remains unsettled. Here we show that the superconductivity in the noncentrosymmetric half-Heusler LuPdBi can be consistently described by the admixture of isotropic even-parity singlet and anisotropic odd-parity septet pairing, whose ratio can be tuned by electron irradiation. From magnetotransport and penetration depth measurements, we find that carrier concentrations and impurity scattering both increase with irradiation, resulting in a nonmonotonic change of the superconducting gap structure. Our findings shed new light on our fundamental understanding of unconventional superconducting states in topological materials.

Modelling and performance comparisons of some ring networks
Creators: name: Nadkarni, Ashok Vasant
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is mainly concerned with the mathematical modelling of some common types of ring networks, i.e., token rings (both the exhaustive and the non-exhaustive service disciplines) and slotted rings. The models described make extensive use of the standard results of queuing theory. The two service disciplines for the token ring display tradeoffs between fairness and system performance. In the case of the slotted rings, an optimum value for the number of stations on the ring is determined which gives minimum or near-minimum delays for all load levels. The correctness of the models is verified by comparing the analytic results with those from simulation. Finally, we summarize interesting results of our models and offer suggestions for further research. The literature contains very little work in this area. Hopefully this thesis has provided new insights into the behaviour of certain ring type local area networks.

description: This paper presents a strategy for control of a spacecraft docking with a non-maneuvering target in the presence of safety constraints and bounded disturbances. The presence of disturbances prevents convergence to a unique docking state, so in our formulation, docking is defined as occurring within a set constructed using prescribed tolerances. Safety is ensured via application of Robust Control Barrier Functions to render a designated safe set forward invariant for any allowable disturbance. However, this safety strategy necessarily presumes a worst-case disturbance, and thus restricts trajectories to a subset of the safe set when a worst-case disturbance is not present. The presented controller accounts for this restriction, and guarantees that the spacecraft both remains safe and achieves docking in finite time for any allowable disturbance. The controller is then validated in simulation for a spacecraft landing on an asteroid, and two spacecraft docking in low Earth orbit.

description: We present details of a high-accuracy absolute scalar magnetometer based on pulsed proton NMR. The $B$-field magnitude is determined from the precession frequency of proton spins in a cylindrical sample of water after accounting for field perturbations from probe materials, sample shape, and other corrections. Features of the design, testing procedures, and corrections necessary for qualification as an absolute scalar magnetometer are described. The device was tested at $B = 1.45$\,T but can be modified for a range exceeding 1--3\,T. The magnetometer was used to calibrate other NMR magnetometers and measure absolute magnetic field magnitudes to an accuracy of 19 parts per billion as part of a measurement of the muon magnetic moment anomaly at Fermilab.

description: Excerpt from the report Introduction: Tree diseases take a heavy annual toll of timber from forests and farm woodlands. Much of this loss is preventable. In the United States as a whole, diseases ruin each year 40 percent as much timber as is cut. Many diseases kill trees or reduce their growth rate, but the major loss to the forest results from those that cause standing timber to decay or otherwise become defective. Trees decaying faster than they are putting on new wood, or so defective they will never produce a usable product, are liabilities rather than assets in the farm woods or forest. The space such trees occupy remains unproductive until they are removed. Much disease damage, such as that caused by rots, does not become evident until timber is cut, and then it is too often accepted as inevitable. Bark diseases that appear as open wounds or cankers on the trunk are often regarded as merely mechanical injuries. Blister rust may be easily overlooked as the cause of death of young white pines. To appraise these losses, it is first necessary to recognize them. To prevent them, the factors that lead to them must be known.

description: In this work, we introduce a novel data-driven formulation, the Koopman-Linearly-Time-Invariant (Koopman-LTI) analysis, for analyzing Fluid-Structure Interactions (FSI). An implementation of the Koopman-LTI on a subcritical free-shear flow over a prism at Re=22,000 corroborated a configuration-wise universal Koopman system, which approximated the configuration's nonlinear dynamics with stellar accuracy. The Koopman-LTI also successfully decomposed the entwined morphologies of raw measurement into a linear superposition of frequency-based constituents. Most importantly, with random and anisotropic turbulence, the Koopman-LTI yielded frequency-wise identical modes for structure response and fluid excitation, thus establishing direct constitutive relations between the phenomenology of fluid and structure.

description: Transverse momentum dependent parton distribution functions, also abbreviated as TMDs, offer a three-dimensional picture of hadrons by taking the intrinsic transverse momentum of the parton into consideration. Hence, they are very important for us to understand the structure of hadrons. In this article, we calculate and summarize all TMDs of quark through the spectator model, from twist-2 to twist-4. Especially, we give complete results of TMDs at twist-4. We adopt a general analytical framework to calculate TMDs, with both scalar and axial-vector spectators being considered. All TMDs are calculated analytically in the light-cone coordinate, and single gluon rescattering is considered to generate T-odd TMDs. T-even TMDs are also calculated to this level, maybe for the first time. Different from the traditional point of view, the twist-4 TMDs can contribute to some physical observables like azimuthal asymmetries. An approximate formula of the Sivers asymmetry, including twist-4 TMDs, is given.

A new approach to program restructuring and clustering
Creators: name: Yap, Tuan-Bin
Publisher: name: University of British Columbia
Year: 2010

description: A new program restructuring algorithm aimed at reducing the working set size of a program executing in a working set environment is developed. The algorithm makes use of the concept of locality as defined in the Bounded Locality Interval (BLI) program behaviour model to discern program referencing patterns. The basic principle of this as well as all other restructuring algorithms is to put relocatable blocks having a prominent referencing pattern in the same virtual pages. Simulation experiments were conducted to evaluate the performance of the new scheme relative to the other existing algorithms. The algorithm was also evaluated on a real system which uses a clock page replacement strategy. A new clustering scheme used in the restructuring procedure is also developed. The new technique decomposes the clustering problem into subproblems which can then be solved individually. The classical hierarchical clustering algorithm yields a time complexity of n³ where n is the number of distinct blocks in the program to be restructured. The decomposition approach reduces the time-complexity of the algorithm to n². Several other practical aspects of program restructuring are also discussed in the thesis.
Iron nanoparticle formation in a metal-organic matrix: from ripening to gluttony

description: A simple method for the fabrication of metal nanoparticles is introduced. Heating metal-organic crystals in vacuum results in the formation of well defined metal particles embedded in a carbon matrix. The method is demonstrated for iron-phthalocyanine. At 500C homogeneously distributed iron nanoparticles with a reasonably narrow size distribution form by nucleation and ripening. After this initial phase the formation kinetics changes drastically. The particles move in the matrix to incorporate material. The "gluttony" phase shows astonishing similarities with the search for nutrition of living micro-organisms. Particle formation, ripening and gluttony are followed in-situ by transmission electron microscopy.

Thermal nature of a generic null surface

description: Dynamical properties of a generic null surface are known to have a thermodynamic interpretation. Such an interpretation is completely based on an analogy between the usual law of thermodynamics and structure of gravitational field equation on the surface. Here we materialise this analogy and show that assigning a temperature on the null surface for a local observer is indeed physically relevant. We find that for a local frame, chosen as outgoing massless chargeless particle (or field mode), perceives a "{\it local unstable Hamiltonian}" very near to the surface. Due to this it has finite quantum probability to escape through acausal null path which is given by Maxwell-Boltzmann like distribution, thereby providing a temperature on the surface.

On the EPR-type Entanglement in the Experiments of Scully et Al. I. The Micromaser Case and Delayed-choice Quantum Erasure
Creators: name: Herbut, Fedor
Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)

description: Delayed-choice erasure is investigated in two-photon two-slit experiments that are generalizations of the micromaser experiment of Scully et al. [Scully, M. O. et al. Nature 351, 111-116 (1991)]. Applying quantum mechanics to the localization detector, it is shown that erasure with delayed choice in the sense of Scully, has an analogous structure as simple erasure. The description goes beyond probabilities. The EPR-type disentanglement, consisting in two mutually incompatible distant measurements, is used as a general framework in both parts of this study. Two simple coherence cases are shown to emerge naturally, and they are precisely the two experiments of Scully et al. The treatment seems to require the relative-reality-of-unitarily-evolving-state (RRUES) approach. Besides insight in the exoeriments, this study has also the goal of insight in quantum mechanics. The question is if it can be more than just a "book-keeping device" for calculating probabilities as Scully et al. modestly and cautiously claim.
