description: Oscillations in coronal loops are usually interpreted in terms of uncoupled magnetohydrodynamic (MHD) waves. Examples of these waves are standing transverse motions, interpreted as the kink MHD modes, and propagating slow modes, commonly reported at the loop footpoints. Here we study a simple system in which fast and slow MHD waves are coupled. The goal is to understand the fingerprints of the coupling when boundary conditions are imposed in the model. The reflection problem of a fast and slow MHD wave interacting with a rigid boundary, representing the line-tying effect of the photosphere, is analytically investigated. Both propagating and standing waves are analysed and the time-dependent problem of the excitation of these waves is considered. An obliquely incident fast MHD wave on the photosphere inevitably generates a slow mode. The frequency of the generated slow mode at the photosphere is exactly the same as the frequency of the incident fast MHD mode, but its wavelength is much smaller, assuming that the sound speed is smaller than the Alfvén speed. The main signatures of the generated slow wave are density fluctuations at the loop footpoints. We have derived a simple formula that relates the velocity amplitude of the transverse standing mode with the density enhancements at the footpoints due to the driven slow modes. Using these results it is shown that there are possible evidences in the observations of the coupling between these two modes.

description: Internet-of-Things (IoT) based solutions are gaining momentum in delivering efficient solutions in health care domain, reducing financial and physical burden on patients and improving ease of treatment for physicians. One such smart health care solution are Serious games. Serious games aid rehabilitation in various fields. For physical rehabilitation, personalization is important for improving training results. A scientific approach for difficulty level design can facilitate players to get effective rehabilitation. The automation of personalized difficulty level design helps the self-guided game-based rehabilitation approach, become simplified and efficient. AI is advancing the design of personalized serious game for rehabilitation through data-driven and individual-oriented methods. In this work, we present Generative AI based design of gamified training plan, especially difficulty level plan which could go beyond rule based solutions. We apply Generative Adversarial Networks (GANs) to address the problem arising from large sequential data and variable requirement. This helps to overcome the limitation of unrealistic long term practice session for a rehabilitation patient by simplifying the training time. When compared with the results from Long Short-Term Memory (LSTM) based approach, our GANs based approach gave a 4.5X less variation in difficulty level and 6.5X less loss which proved the efficacy of our proposed approach in generating accurate difficulty levels. When compared with existing literature our proposed work simultaneously performs better on various parameters namely faster convergence, minimum emphasis on past performance of players, low data requirement for training and demographic flexibility.
Waves in pulsar winds

description: The radio, optical, X-ray and gamma-ray nebulae that surround many pulsars are thought to arise from synchrotron and inverse Compton emission. The energy powering this emission, as well as the magnetic fields and relativistic particles, are supplied by a "wind" driven by the central object. The inner parts of the wind can be described using the equations of MHD, but these break down in the outer parts, when the density of charge carriers drops below a critical value. This paper reviews the wave properties of the inner part (striped wind), and uses a relativistic two-fluid model (cold electrons and positrons) to re-examine the nonlinear electromagnetic modes that propagate in the outer parts. It is shown that in a radial wind, two solutions exist for circularly polarised electromagnetic modes. At large distances one of them turns into a freely expanding flow containing a vacuum wave, whereas the other decelerates, corresponding to a confined flow.

description: Mono- and Di-t-Butylcyclopentadienyl Carbonyl Complexes of Iron and Molybdenum - Crystal Structure of [CpMo(CO)2]2 (Cp = n5-C5H3-t-Bu2-1,3) Cothermolysis of M(CO)m (M = Fe, m = 5; M = Mo, m = 6) with t-Bu-substituted cyclopentadienyls constitutes a simple synthesis of complexes of the type [Cp*M(CO)n]2 (CP* = n5-C5H3 (t-Bu), R, R = H, t-Bu; M = Fe, Mo; n = 2, 3). Each synthesis has an optimal temperature. The yield of Fe complexes decreases at temperatures above 130°C because of decomposition of the product. Optimal yields of [Cp*Mo(CO)3]2 are obtained at 130-140°C, whereas at 160°C complexes of the type [Cp*Mo(CO)2]2 with formal MoMo triple bonds are obtained. The structure of the complexes is discussed on the basis of 1H-, 13C-NMR, IR, and mass spectrometry. The structure of [CpMo(CO)2]2 (Cp = n5-C5H3t-Bu2-1,3) was determined by X-ray crystallography at -95°C. It crystallises in the space group Pbca, with cell constants a = 1808.6(6), b = 1308.5(4), c = 2507.9(9) pm, Z = 8, R = 0.031 for 3794 reflections. The MoMo bond length of 253.3 pm is very long for a formal triple bond. The CpMoMoCp axis is non-linear.

description: Anomalous decoherence in the Jaynes-Cummings model emerges for a certain class of bosonic reservoirs, described by spectral densities with a band edge frequency coinciding with the qubit transition frequency. The special reservoirs are piecewise similar to those usually adopted in Quantum Optics, i.e., sub-ohmic at low frequencies and inverse power laws at high frequencies. The exact dynamics of the qubit is described analytically through Fox $H$-functions. Over estimated long time scales, decoherence results in inverse power laws with powers decreasing continuously to unity, according to the particular choice of the special reservoir. The engineering reservoir approach is a new way of strongly delaying the decoherence process with possible applications to Quantum Technologies, due to the simple form of the designed reservoirs.

description: The crystal and molecular structure of 5-t-butyl-5-aza-2,8-dithia-1-stanna(II)bicyclo[3.3.01,5]octane [Sn(SC2H4)2NC4H9]2 have been determined from three-dimensional X-ray data. The crystals are monoclinic, space group P21/c, with cell dimensions: a 14.104(2), b 21.911(4), c 11.624(2) Å, β 98.73(1)°, Z = 6. The final R is 0.040 for the 4279 observed reflections. The unit-cell contains four asymmetric dimers (dimer a) and two centrosymmetric dimers (dimer b), each dimer forms a four-membered Sn2S2 ring in which the sulfur atoms are three-coordinated. The Sn---N distances in the two dimeric forms are significantly different (namely, 2.64 and 2.75 in dimer a, 2.97 Å in dimer b). The lengthening of the Sn---N distances involves the shortening of the bridging tin—sulfur bonds (2.99 and 2.79 in a, 2.71 Å in b). The coordination around the three different Sn atoms is hemispherical.

Laboratory and discrete element study of proppant crushing and embedment and their influence on fracture conductivity
Creators: name: Zheng, Wenbo
Publisher: name: University of British Columbia
Year: 2017

description: Proppants are widely used in hydraulic fracturing for unconventional resources to increase the recovery rate of hydrocarbons in the oil and gas industry. More than 55 million tonnes of proppants were supplied for hydraulic fracturing in 2015 to fracture more than 35,000 wells. During hydraulic fracturing, proppants are transported by fracturing fluids into fractures to form a permeable proppant pack, which acts as a path for hydrocarbons to flow to wellbores. When high closure stresses exist, proppants can be crushed into smaller fragments and embed into fracture surfaces, which reduces the propped fracture conductivity by decreasing the proppant pack permeability and thickness. Choosing a suitable proppant for hydraulic fracturing is key to success in recovering hydrocarbons. Compared with time-consuming laboratory tests and simplified empirical/numerical models, the discrete element method (DEM) is a natural approach for simulating proppant crushing and embedment into fracture faces. However, current DEM simulations have not considered proppant crushing under high closure stresses. In addition, the mechanical properties of different proppants have not been fully characterised thus modelling of proppants in DEM lacks verification. Moreover, DEM simulations of proppant embedment into rock surface have not been calibrated/compared with laboratory hardness tests on rock faces. Finally, the influence of proppant crushing and embedment on proppant selection has not been thoroughly studied. With these in mind, this research presents comprehensive laboratory experiments on proppant crushing which were used to calibrate discrete element models of proppant crushing and proppant embedment. Three objectives are accomplished within this research: (1) characterize the mechanical behaviour of proppant crushing and proppant embedment into fracture surfaces; (2) model proppant crushing and proppant embedment with DEM; (3) study the influence of proppant crushing and proppant embedment on hydraulic fracture conductivity and recommend optimal proppant usage for hydraulic fracturing. The results deliver a better understanding of the crushing characteristics of different proppants, and improve DEM modelling of proppant crushing and embedment into hydraulic fractures, which provides a cost-efficient approach for evaluating the proppant performance for hydraulic fracturing without the need to conduct problematic hydraulic conductivity experiments.

The Erpenbeck high frequency instability theorem for ZND detonations

description: The rigorous study of spectral stability for strong detonations was begun by J.J. Erpenbeck in [Er1]. Working with the Zeldovitch-von Neumann-Döring (ZND) model, which assumes a finite reaction rate but ignores effects like viscosity corresponding to second order derivatives, he used a normal mode analysis to define a stability function $V(τ,\eps)$ whose zeros in $\Re τ>0$ correspond to multidimensional perturbations of a steady detonation profile that grow exponentially in time. Later in a remarkable paper [Er3] he provided strong evidence, by a combination of formal and rigorous arguments, that for certain classes of steady ZND profiles, unstable zeros of $V$ exist for perturbations of sufficiently large transverse wavenumber $\eps$, even when the von Neumann shock, regarded as a gas dynamical shock, is uniformly stable in the sense defined (nearly twenty years later) by Majda. In spite of a great deal of later numerical work devoted to computing the zeros of $V(τ,\eps)$, the paper \cite{Er3} remains the only work we know of that presents a detailed and convincing theoretical argument for detecting them. The analysis in [Er3] points the way toward, but does not constitute, a mathematical proof that such unstable zeros exist. In this paper we identify the mathematical issues left unresolved in [Er3] and provide proofs, together with certain simplifications and extensions, of the main conclusions about stability and instability of detonations contained in that paper. The main mathematical problem, and our principal focus here, is to determine the precise asymptotic behavior as $\eps\to \infty$ of solutions to a linear system of ODEs in $x$, depending on $\eps$ and a complex frequency $τ$ as parameters, with turning points $x_*$ on the half-line $[0,\infty)$.

description: Information-centric networking (ICN) allows data to be cached at each node in the network. It is vital in vehicular networks (VNs) to improve caching performance and reduce content delay in high-traffic scenarios. In cooperative VNs, the requested content can be cached in the base station or nearby nodes without fetching the requested content from the server. The existing content popularity approaches face challenges in predicting popular content due to a time-varying environment, resulting in popularity being changed frequently. It is hard to predict such content in highly dynamic vehicular traffic. Therefore, the current approaches are less practical in a realistic scenario. This paper proposes an intelligent caching method for massive traffic in VNs to address these issues based on deep transfer learning (DTL). The primary purpose of this study is to reduce the system cost and content delay by increasing the cache hit rate based on popular data in dynamic traffic. The proposed solution uses a collaborative cache with social interaction among clusters to share the most popular content (MPC). Furthermore, it designs a time-varying mechanism to predict content popularity in a highly dynamic environment and share the widespread knowledge with other target nodes based on DTL. In addition, a content update method is developed to address the content replacement in a cooperative cache environment. Based on thorough analysis and evaluation, similar and dissimilar contents on base stations are classified among source and target clusters. The extensive simulation and experimentation confirm that the developed work achieved better than baseline studies.

description: The locomotor activity patterns of wildtype Drosophila melanogaster and the mutants so (sine oculis) and sol (small optic lobes) were investigated. In all strains the proportions showing circadian rhythmicity, arrhythmicity and more complex patterns which could not be thus classified were similar. The occurrence of abnormal activity patterns is thus not a property of the mutation as previously claimed (Mack & Engelmann, 1981). In flies with a distinct circadian rhythmicity, the period lengths (τ) varied between strains, τ for wildtype Italy and the mutant so was longer than for wildtype Berlin and the mutant sol. As different τ's have been reported by others, τ does not seem to be closely determined for Drosophila melanogaster. Many flies exhibited two rhythms simultaneously, one with τ shorter and one with τ longer than 24 h, apparently implying two-oscillator control of the locomotor activity. The eyeless so mutants were entrained by LD cycles, so the compound eyes are not necessary, and so must possess the relevant photoreceptor(s) elsewhere. This may therefore also be true for the wildtype. Histology of the so adults revealed no correlation between the degree of reduction in the medulla and the occurrence of abnormal activity patterns. Since the only structures common to the medulla of so and sol are known to be large tangential cells, it is concluded that either they are of importance for the rhythmic system, or the oscillator(s) controlling locomotor activity is (are) not located in the medulla.

description: Finding interdependency relations between (possibly multivariate) time series provides valuable knowledge about the processes that generate the signals. Information theory sets a natural framework for non-parametric measures of several classes of statistical dependencies. However, a reliable estimation from information-theoretic functionals is hampered when the dependency to be assessed is brief or evolves in time. Here, we show that these limitations can be overcome when we have access to an ensemble of independent repetitions of the time series. In particular, we gear a data-efficient estimator of probability densities to make use of the full structure of trial-based measures. By doing so, we can obtain time-resolved estimates for a family of entropy combinations (including mutual information, transfer entropy, and their conditional counterparts) which are more accurate than the simple average of individual estimates over trials. We show with simulated and real data that the proposed approach allows to recover the time-resolved dynamics of the coupling between different subsystems.

description: We consider Thompson's groups from the perspective of mapping class groups of surfaces of infinite type. This point of view leads us to the braided Thompson groups, which are extensions of Thompson's groups by infinite (spherical) braid groups. We will outline the main features of these groups and some applications to the quantization of Teichmüller spaces. The chapter provides an introduction to the subject with an emphasis on some of the authors results.

description: Expression of newly cloned cDNAs in mammalian cell lines is an essential tool for the functional analysis of the proteins encoded by these cDNAs. In many instances, however, evaluation of the protein is difficult because of the difficulty in purification of the expressed protein and/or the lack of specific antibodies which react with the proteins on Western blots or for immunocytochemistry or immunoprecipitation. A number of gene fusion systems have been employed in which a known peptide is fused to the expression product of interest and the fusion protein is purified using affinity chromatography and identified in extracts or by immunocytochemistry using antibodies directed against the affinity handle peptide. The DNA-binding domain of the yeast transcription factor GAL4 is widely used to construct fusion proteins with putative transcription factors to evaluate potential trans-acting domains. Because of the lack of commercially available anti-GAL4 antibodies, the further biochemical characterization of these fusion proteins has remained difficult. We describe the construction of two mammalian expression vectors, pMFH/GAL4 and pMFH2/GAL4 (where pMFH stands for pM2, Flag, Histidine tail), which encode the DNA-binding domain of the yeast transcription factor GAL4 with a Flag peptide (consisting of the 11-amino-acid leader peptide of the gene 10 product from bacteriophage T7) at the NH2-terminus and a tail of six histidines at the COOH-terminus. Unique restriction sites allow both the construction of fusion proteins with the GAL4 DNA-binding domain and the replacement of the GAL4 fragment with another insert. Proteins encoded by this vector are biologically active, can be easily precipitated and purified by interaction of its histidine tail with immobilized Ni2+, and can be visualized on Western blots with an antibody against the Flag peptide.

description: We present a detailed phenomenological analysis of single-inclusive hadron production at the CERN-LHC in both proton-proton and proton-lead collisions. First data from the LHC experiments on charged hadron spectra are compared to next-to-leading order QCD expectations, and predictions are made for identified pion, kaon, and proton distributions differential in transverse momentum and rapidity for LHC energies from 900 GeV to 14 TeV. The results are obtained with the latest sets of vacuum fragmentation functions based on global QCD analyses, and recently proposed medium modified fragmentation functions are used to model hadronization in proton-lead collisions assuming standard QCD factorization. Besides estimating theoretical ambiguities due to the choice of factorization and renormalization scales and parton densities, we carefully assess uncertainties due to our present knowledge of parton-to-hadron fragmentation functions with the Lagrange multiplier technique. It is outlined to what extent future LHC data will contribute to further our quantitative understanding of hadronization processes.

The targum (1878:Jan.)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1878

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Fiji National University is encountering many difficulties with its current administrative systems. These difficulties include accessibility, scalability, performance, flexibility and integration. We propose a new campus information system, FNU-CIS to addresses these difficulties. FNU-CIS has the potential to provide wide range of the services for students and staffs at the university. In order to assist in the design and implementation of proposed FNU-CIS, we present an overview, software architecture and prototype implementation of our proposed system. We discuss the key properties of our system, compare it with other similar systems available and outline our future plans for research in FNU-CIS implementation.

Beam-tracing prediction of room-to-room sound transmission
Creators: name: Mahmud, Md Amin
Publisher: name: University of British Columbia
Year: 2017

description: Modeling sound transmission is a challenging task. An existing beam-tracing model for empty, parallelepiped rooms with specularly-reflecting surfaces is extended to predict room-to-room sound transmission between a source and receiver rooms separated by a common wall. This wall is modeled as one locally-reacting homogenous partition with frequency-independent transmission loss. Besides, sound transmission is modeled in Ray-Tracing (CATT-TM) and FEM (COMSOL). A reference configuration consists of two identical reverberation rooms is chosen following the recommendations of the literature and most of the prescriptions of the reverberation room standard, ASTM 3423. The capability of various room-to-room predictions models, in particular, the phase and energy-based beam tracing models (PBTM, EBTM) in reproducing the results of the diffuse-field theory is investigated. Both EBTM and CATT-TM are found to be reasonably accurate in reproducing the diffuse sound field for a reverberation room (i.e. for diffuse sound fields). However, the predicted levels deviate considerably from the diffuse-field theory with changes in the acoustical characteristics of the room (room aspect ratio, the magnitude of the surface absorption and surface absorption distribution (i.e. for non-diffuse sound fields). EBTM has been validated in both source and receiver rooms through existing results from ODEON in the literature and by comparing the prediction results with the new CATT-TM for the reference configuration. PBTM has been compared with finite element method (COMSOL) results in the low-frequency region. Both phase-based models match well in source room with a reasonable discrepancy. However, the PBTM has not reproduced the sound field predicted by COMSOL in the receiver room. Moreover, Waterhouse effect is studied by both PBTM and EBTM model in the reverberation rooms which is ignored in the classical diffuse-field concept. However, its significant effect is exhibited near the reflecting boundaries inside the reverberation room only in the PBTM predictions. Hence, based on recommendations of the ASTM standards during measuring sound transmission between rooms, sources and receivers should be placed sufficiently far away from the reflecting surfaces, edges and corners of the rooms to avoid the errors due to the Waterhouse effect.

Mining power : subnational participation in social conflicts in Peru
Creators: name: Hurtado Lozada, Enilda Veronica Beatriz
Publisher: name: University of British Columbia
Year: 2017

description: Rising levels of social mobilization occurred throughout the period of the recent commodity boom in the Andes (2000-2013), adding leverage to the resource curse literature. Surprisingly, the mobilizations have incorporated a new active participant: mayors and governors. They have been participating in the mobilizations, both peacefully and violently, often attracting the attention of the mass media and national authorities. The participation of subnational authorities in these mobilizations is a new phenomenon, one that has not yet been systematically studied. This research deepens our understanding of the resource curse and its impact in Latin American democracies by showing how the participation of subnational authorities in social conflicts is motivated by mining-extraction dependency and political weakness.

description: Using optical pulses of variable duration up to 80 ps, we report on spin coherence initialization and its subsequent detection in n-type singly-charged quantum dots, subject to a transverse magnetic field, by pump-probe techniques. We demonstrate experimentally and theoretically that the spin coherence generation and readout efficiencies are determined by the ratio of laser pulse duration to spin precession period: An increasing magnetic field suppresses the spin coherence signals for a fixed duration of pump and/or probe pulses, and this suppression occurs for smaller fields the longer the pulse duration is. The reason for suppression is the varying spin orientation due to precession during pulse action.
