description: Dask is a distributed task framework which is commonly used by data scientists to parallelize Python code on computing clusters with little programming effort. It uses a sophisticated work-stealing scheduler which has been hand-tuned to execute task graphs as efficiently as possible. But is scheduler optimization a worthwhile effort for Dask? Our paper shows on many real world task graphs that even a completely random scheduler is surprisingly competitive with its built-in scheduler and that the main bottleneck of Dask lies in its runtime overhead. We develop a drop-in replacement for the Dask central server written in Rust which is backwards compatible with existing Dask programs. Thanks to its efficient runtime, our server implementation is able to scale up to larger clusters than Dask and consistently outperforms it on a variety of task graphs, despite the fact that it uses a simpler scheduling algorithm.

description: We describe and benchmark a method to accurately calculate the quantum droplet states that can be produced from a dipolar Bose-Einstein condensate. Our approach also allows us to consider vortex states, where the atoms circulate around the long-axis of the filament shaped droplet. We apply our approach to determine a phase diagram showing where self-bound droplets are stable against evaporation, and to quantify the energetics related to the fission of a vortex droplet into two non-vortex droplets.

description: Stack interchanges are essential components of transportation systems. Mobile laser scanning (MLS) systems have been widely used in road infrastructure mapping, but accurate mapping of complicated multi-layer stack interchanges are still challenging. This study examined the point clouds collected by a new Unmanned Aerial Vehicle (UAV) Light Detection and Ranging (LiDAR) system to perform the semantic segmentation task of a stack interchange. An end-to-end supervised 3D deep learning framework was proposed to classify the point clouds. The proposed method has proven to capture 3D features in complicated interchange scenarios with stacked convolution and the result achieved over 93% classification accuracy. In addition, the new low-cost semi-solid-state LiDAR sensor Livox Mid-40 featuring a incommensurable rosette scanning pattern has demonstrated its potential in high-definition urban mapping.

Irreversibility of entanglement loss

subject: FOS: Physical sciences

description: The action of a channel on a quantum system, when non trivial, always causes deterioration of initial quantum resources, understood as the entanglement initially shared by the input system with some reference purifying it. One effective way to measure such a deterioration is by measuring the loss of coherent information, namely the difference between the initial coherent information and the final one: such a difference is ``small'', if and only if the action of the channel can be ``almost perfectly'' corrected with probability one. In this work, we generalise this result to different entanglement loss functions, notably including the entanglement of formation loss, and prove that many inequivalent entanglement measures lead to equivalent conditions for approximate quantum error correction. In doing this, we show how different measures of bipartite entanglement give rise to corresponding distance-like functions between quantum channels, and we investigate how these induced distances are related to the cb-norm.

description: Retrieving classical information encoded in optical modes is at the heart of many quantum information processing tasks, especially in the field of quantum communication and sensing. Yet, despite its importance, the fundamental limits of optical mode discrimination have been studied only in few specific examples. Here we present a toolbox to find the optimal discrimination of any set of optical modes. The toolbox uses linear and semi-definite programming techniques, which provide rigorous (not heuristic) bounds, and which can be efficiently solved on standard computers. We study both probabilistic and unambiguous single-shot discrimination in two scenarios: the "channel-discrimination scenario", typical of metrology, in which the verifier holds the light source and can set up a reference frame for the phase; and the "source-discrimination scenario", more frequent in cryptography, in which the verifier only sees states that are diagonal in the photon-number basis. Our techniques are illustrated with several examples. Among the results, we find that, for many sets of modes, the optimal state for mode discrimination is a superposition or mixture of at most two number states; but this is not general, and we also exhibit counter-examples.

description: Cell type diversity is the defining characteristic of multicellular organisms. Traditionally, cell types are defined based on morphological features and surface markers. With the advancement of modern experimental tools, such as single-cell RNA-sequencing (scRNA-Seq), it has become possible to acquire the full transcriptome of individual cells, thereby making it possible to define cell types based on the similarity of expression profiles in a data-driven manner. However, due to the large degree of variability in gene expression and the high dimensionality of the transcriptome, the clustering of cells based on their expression profiles remains a challenging problem. We present a novel method, Single-Cell Consensus Clustering (SC3), for the unsupervised clustering of cells from scRNA-Seq experiments. The key element of SC3 is to combine the results from several general-purpose clustering methodologies to increase the accuracy of the classification significantly. To remain computationally efficient, SC3 parallelizes the clustering steps and pools them together at the final step. In addition, SC3 can handle datasets with tens of thousands of cells (e.g. from Drop-Seq experiments) by using Support Vector Machines (SVM). A key feature of SC3 is a user-friendly interface which allows one to validate the clustering in real-time, not only by objective criteria but also through direct visual examination. We have tested SC3 on various scRNA-Seq data sets and we show that it can outperform other recently developed methods.  SC3 also provides biological insights by identifying differentially expressed genes, marker genes and cell outliers (e.g. rare cell types) across the obtained cell clusters. In summary, SC3 is fast, accurate, interactive and scalable, and we believe it could provide a platform of wide applicability in experimental laboratories.

description: We report on the results of detailed spectral studies of the ultra-luminous X-ray source (ULX), M81 X-9 (Holmberg IX X-1), made with XMM-Newton on 2001 April 22 and with ASCA on 1999 April 6. On both occasions, the source showed an unabsorbed 0.5-10 keV luminosity of ~2E40 erg/s (assuming a distance of 3.4Mpc) and a soft spectrum apparently represented by a multi-color disk model with an innermost disk temperature of 1.3-1.5 keV. Adding a power-law model further improved the fit. However, as previously reported, the high luminosity cannot be reconciled with the high disk temperature within a framework of the standard accretion disk radiating at a sub-Eddington luminosity. Therefore, we modified the multi-color disk model, and allowed the local disk temperature to scale as r^(-p) on the distance r from the black hole, with p being a free parameter. We then found that the XMM-Newton and the ASCA spectra can be both reproduced successfully with p~0.6 and the innermost disk temperature of 1.4-1.8 keV. These flatter temperature profiles suggest deviation from the standard Shakura-Sunyaev disk, and are consistent with predictions of a slim disk model.

Expression, purification and properties of papaya mosaic virus capsid protein in Escherichia coli
Creators: name: Rampersaud, Anand
Publisher: name: University of British Columbia
Year: 2009

description: Potexviruses are composed of a single species of capsid (coat) protein (CP) which encapsidates a single positive-sense genomic RNA (gRNA) and is also implicated in cell-to cell movement. Several potexviruses have been reconstituted from their individual purified components and, of these, papaya mosaic virus (PMV) has been most extensively characterized. Capsid protein mutants that affect encapsidation and/or movement usually cannot, however, be efficiently recovered from plants. Accordingly, an alternative system was designed to permit the generation of a broad range of mutant CPs for the systematic investigation of the role of potexviral CP in assembly which would otherwise be impossible in planta. To test the general feasibility of this approach, I have overexpressed PMV CP and CYMV CP in E. coli. The PMV CP has been purified to approximately 90 % purity using only four steps: centrifugation at 30,000 x g, ammonium sulphate precipitation to 40 % saturation, anion exchange chromatography and gel filtration chromatography. Recombinant CP was assayed for its in vitro reconstitutive ability with genomic PMV RNA via electron microscopy and local lesion host infectivity. Reconstitution was demonstrated, but it was suboptimal as evidenced by the formation of partial rods and the inability of reconstituted viral particles exposed to Tl RNase to infect a local lesion host.

The formulation of the BDDC method shows that it is the same as P-FETI-DP and the same as a preconditioner introduced by Cros. We prove the equality of eigenvalues of a particular case of the FETI-1 method and of the BDD method by applying a recent abstract result by Fragakis.

In the present paper, we describe both methodologically (by proposing annotation principles) and technically (by creating the required training data and the relevant models) the production of a linguistic tagger for (early) modern French (16-18th c.), taking as much as possible into account already existing standards for contemporary and, especially, medieval French.

description: We study the isospin breaking effect on octet baryons. Using the two-flavor dynamical domain-wall QCD configurations combined with the quenched non-compact QED configurations, the electromagnetic mass splittings between isomultiplets (p, n), (Sigma^+, Sigma^0, Sigma^-), (Xi^0, Xi^-) are investigated. We evaluate the main source of statistical fluctuations in the two-point correlation function, and find that the elimination of O(e) fluctuation (e: the QED charge) is essential to extract the signal. Preliminary results for $m_p - m_n$ as well as other mass splittings are presented. Possible origin of systematic uncertainty is also discussed.

description: We report the results of an analysis, based on a straightforward quantum-mechanical model, of shot noise suppression in a structure containing cascaded tunneling barriers. Our results exhibit a behavior that is in sharp contrast with existing semiclassical models for this particular type of structure, which predict a limit of 1/3 for the Fano factor as the number of barriers is increased. The origin of this discrepancy is investigated and attributed to the presence of localization on the length scale of the mean free path, as a consequence of the strictly 1-dimensional nature of disorder, which does not create mode mixing, while no localization appears in common semiclassical models. We expect localization to be indeed present in practical situations with prevalent 1-D disorder, and the existing experimental evidence appears to be consistent with such a prediction.

description: The electronic and atomic structure of a bulk 2D layered van-der-Waals compound CdPS3 was studied in the low (R3) and room (C2/m) temperature phases using first-principles calculations within the periodic linear combination of atomic orbitals method with hybrid meta exchange-correlation M06 functional. The calculation results reproduce well the experimental crystallographic parameters. The value of the indirect band gap Eg=3.4 eV for the room-temperature monoclinic C2/m phase is close to the experimental one, while the indirect band gap Eg=3.3 eV was predicted for the low-temperature trigonal R3 phase. The effect of hydrostatic pressure on the band gap in both phases was studied in the pressure range from 0 to 40 GPa. In both cases, the pressure dependence of the band gap passes through a maximum, but at different pressures. In the R3 phase, the band gap reaches its maximum value of ~4 eV at ~30 GPa, whereas in the C2/m phase, the maximum value of ~3.6 eV is reached already at ~8 GPa.
Reliability Aware Multiple Path Installation in Software Defined Networking

Subjects: subject: Networking and Internet Architecture (cs.NI)

description: Being a state-of-the-art network, Software Defined Networking (SDN) decouples control and management planes from data plane of the forwarding devices by implementing both the control and management planes at logically centralized entity, called controller. This helps to make simple and easy both the network control and management. Failure of links occurs frequently in a computer network. To deal with the link failures, the existing approaches computes and installs multiple paths for a flow at the switches in SDN without considering the reliability value of the primary path. This incurs extra computation to compute multiple paths, and both increased computation time and traffic to install extra flow rules in the network. In this research work we propose a new approach that calculates the link reliability and then installs the number of multiple paths based on the reliability value of the primary path. More specifically, if a primary path has higher reliability then a smaller number of alternative paths should be installed. This shall decrease the path computational time and flow rule installation load at controller. Resultantly there shall be less flow rule entries in switch flow table which in turn will avoid the overflow of the flow table. Through simulation results, our proposed approach performs better as compared to the existing approach in term of computational overhead at controller, end-to-end delay for packet deliver and the traffic overhead for flow rule installation.

description: The entanglement between spatial regions in an interacting Bose-Einstein condensate is investigated using a quantum field theoretic formalism. Regions that are small compared to the healing length are governed by a non-relativistic quantum field theory in the vacuum limit, and we show that the latter has vanishing entanglement. In the opposite limit of a region that is large compared to the healing length, the entanglement entropy is like in the vacuum of a relativistic theory where the velocity of light is replaced with the velocity of sound and where the inverse healing length provides a natural ultraviolet regularization scale. Besides the von Neumann entanglement entropy, we also calculate Rényi entanglement entropies for a one-dimensional quasi-condensate.

description: La$_{1.5}$Sr$_{0.5}$CoMn$_{0.5}$Fe$_{0.5}$O$_{6}$ (LSCMFO) compound was prepared by solid state reaction and its structural, electronic and magnetic properties were investigated. The material forms in rhombohedral $R\bar{3}c$ structure, and the presence of distinct magnetic interactions leads to the formation of a Griffiths phase above its FM transition temperature (150 K), possibly related to the nucleation of small short-ranged ferromagnetic clusters. At low temperatures, a spin glass-like phase emerges and the system exhibits both the conventional and the spontaneous exchange bias (EB) effects. These results resemble those reported for La$_{1.5}$Sr$_{0.5}$CoMnO$_{6}$ but are discrepant to those found when Fe partially substitutes Co in La$_{1.5}$Sr$_{0.5}$(Co$_{1-x}$Fe$_{x}$)MnO$_{6}$, for which the EB effect is observed in a much broader temperature range. The unidirectional anisotropy observed for LSCMFO is discussed and compared with those of resembling double-perovskite compounds, being plausibly explained in terms of its structural and electronic properties.

description: We present the results of six Suzaku observations of the recurrent black hole transient 4U1630-472 during its decline from outburst from February 8 to March 23 in 2006. All observations show the typical high/soft state spectral shape in the 2-50keV band, roughly described by an optically thick disk spectrum in the soft energy band plus a weak power-law tail that becomes dominant only above \~20keV. The disk temperature decreases from 1.4keV to 1.2keV as the flux decreases by a factor 2, consistent with a constant radius as expected for disk-dominated spectra. All the observations reveal significant absorption lines from highly ionized (H-like and He-like) iron Ka at 7.0keV and 6.7keV. The brightest datasets also show significant but weaker absorption structures between 7.8keV and 8.2keV, which we identify as a blend of iron Kb and nickel Ka absorption lines. The energies of these absorption lines suggest a blue shift with an outflow velocity of ~1000km/s.. The H-like iron Ka equivalent width remains approximately constant at ~30 eV over all the observations, while that of the He-like Ka line increases from 7 eV to 20 eV. Thus the ionization state of the material decreases, as expected from the decline in flux. We fit the profiles with Voigt functions (curve of growth) to derive absorbing columns, then use these together with detailed photo-ionization calculations to derive physical parameters of the absorbing material. The data then constrain the velocity dispersion of the absorber to 200-2000 km/s, and the size of the plasma as ~1E10 cm assuming a source distance of 10 kpc.

A comparison of artificial neural network and linear statistical models for the detection of glaucoma based on measurements of the optic nerve head collected with a scanning laser ophthalmoscope
Creators: name: Parfitt, Craig Michael
Publisher: name: University of British Columbia
Year: 2009

description: The scanning laser ophthalmoscope is a device used by ophthalmologists to obtain topographic images of patients' optic nerve heads (ONHs). Measurements are taken from these images that quantitatively describe the shape of the ONH. Glaucoma involves the loss of retinal nerve fibers, which in turn produces a change in the ONH shape. However, it is not known which shape parameters are most relevant for the diagnosis of glaucoma. To solve this problem, a forward stepping linear discriminant function analysis (DFA), and a non-linear feedforward artificial neural network (ANN) were used to build classification models for patient data. Patients were first independently classified using perimetry data (visual fields) into normal and abnormal (glaucomatous) groups. The DFA built a classification function based upon individual entry of variables into the model using the F statistic as the entry criterion at each step. The classification function was validated using a jackknife validation method which removes bias from the model. The ANN was trained with error back-propagation using the conjugate gradient method to update the synaptic weights. The entire data set (45 normals and 44 abnormals) was utilized for cross validation, one normal and one glaucoma each time. The error rate of the training set was required to be less than 20% to ensure valid network convergence. The DFA had a diagnostic precision of 88.8% {86.7% specificity and 90.9% sensitivity} with a jackknife validation of 87.6% {86.7% specificity and 88.6% sensitivity}. The ANN trained with an average training classification rate of 87.8% with a cross validated classification rate of 87.8% {86.7% specificity and 88.8% sensitivity}. Receiver operating characteristic curve analysis showed that both classification models were comparable; ROC area was 0.916 for DFA and 0.879 for ANN. Both the DFA and the ANN classification generalized well, which indicates that the ONH measurements are useful for the detection of glaucoma.

In the present paper this criterion is extended to translation invariant weighted algebras $L_p^w(G)$ with $p>1$. Regular algebras $L_p^w(G)$ are constructed on any sigma-compact abelian group $G$. It was proved earlier by the author that sigma-compactness is necessary (in the abelian case) for the existence of weighted algebras $L_p^w(G)$ with $p>1$.

The most common strategy was that of an individual being a dominant male, and controlling access (through direct aggression) of other males to a reproductive female. A less common strategy was that of an individual being a sneaker male, and not engaging in aggressive encounters with other males to gain access to a female. Dominant males and sneaker males differed significantly in size (length and mass), growth, reproductive pattern, morphology (mainly kype growth) and sexual colouration. Sneaker males were more similar in morphology and colouration to reproductive females, suggesting that female mimicry by sneaker males may be occurring. Dominant males were observed to be more aggressive to other large brightly coloured males than they were to smaller and duller coloured males. Experimental trials on dominant male aggression towards coloured models demonstrated that dominant males were more aggressive towards brightly coloured (male like) models than they were towards less coloured (female like) models. These results suggested that the reduced secondary sexual characteristics of sneaker males may enable them to get within close proximity to a spawning pair to allow sneak fertilizations. These studies demonstrate that variation in male reproductive strategies occur, and provide the possible mechanism by which smaller males may spawn successfully without actively courting or guarding a female. In terms of sexual selection the study suggests that as the spawning period progresses, there may be a shift in which type of strategy is at an advantage. Microhabitat at bull trout redd sites was also measured, and found to be similar to data reported from other northern latitudes. Bull trout were highly specific in areas of the upper river where they spawned, and where a high degree of redd superimposition was observed. Bull trout females selected areas of groundwater discharge for spawning that may provide high quality incubation sites for eggs. An experiment designed to measure egg to alevin survival at selected and non-selected sites with similar habitat attributes other than groundwater infiltration, demonstrated that egg to alevin survival was significantly higher at selected sites than randomly available sites. The areas selected for spawning were areas of groundwater discharge and had more stable and warmer incubation temperatures than non-selected sites. This study has conclusively demonstrated that bull trout do spawn in areas of groundwater upwelling, and that individual female's reproductive success may be increased by site selection.

description: High-lying Rydberg states of Mott-Wannier excitons are receiving considerable interest due to the possibility of adding long-range interactions to the physics of exciton-polaritons. Here, we study Rydberg excitation in bulk synthetic cuprous oxide grown by the optical float zone technique and compare the result with natural samples. X-ray characterization confirms both materials are mostly single crystal, and mid-infrared transmission spectroscopy revealed little difference between synthetic and natural material. The synthetic samples show principal quantum numbers up to $n=10$, exhibit additional absorption lines, plus enhanced spatial broadening and spatial inhomogeneity. Room temperature and cryogenic photoluminescence measurements reveal a significant excess of copper vacancies in the synthetic material. These measurements provide a route towards achieving \mbox{high-$n$} excitons in synthetic crystals, opening a route to scalable quantum devices.

description: In this paper, we introduce a novel quantum photonic device, which we term photonic Bier-Glass cavity. We discuss its fabrication and functionality, which is based on the coupling of integrated In(Ga)As quantum dots to a broadband photonic cavity resonance. By design, the device architecture uniquely combines the Purcell enhancement of a photonic micropillar structure with broadband photonic mode shaping of a vertical, tapered waveguide, making it an interesting candidate to enable the efficient extraction of entangled photon pairs. We detail the epitaxial growth of the heterostructure and the necessary lithography steps to approach a GaAs-based photonic device with a height exceeding 15 $μ$m, supported on a pedestal that can be as thin as 20 nm. We present an optical characterization, which confirms the presence of broadband optical resonances, in conjunction with amplified spontaneous emission of single photons.

description: Human societies are characterized, besides others, by three constituent features. (A) Options, as for jobs and societal positions, differ with respect to their associated monetary and non-monetary payoffs. (B) Competition leads to reduced payoffs when individuals compete for the same option with others. (C) People care how they are doing relatively to others. The latter trait, the propensity to compare one's own success with that of others, expresses itself as envy. It is shown that the combination of (A)-(C) leads to spontaneous class stratification. Societies of agents split endogenously into two social classes, an upper and a lower class, when envy becomes relevant. A comprehensive analysis of the Nash equilibria characterizing a basic reference game is presented. Class separation is due to the condensation of the strategies of lower-class agents, which play an identical mixed strategy. Upper class agents do not condense, following individualist pure strategies. Model and results are size-consistent, holding for arbitrary large numbers of agents and options. Analytic results are confirmed by extensive numerical simulations. An analogy to interacting confined classical particles is discussed.

description: We report neutron diffraction measurements on CeNi4Mn, which has recently been identified as a soft ferromagnet (Tc ~ 140 K) with a sizeable spin-transport polarization. Our data show conclusively that the Mn atoms occupy a unique site (4c) in the unit cell, which has the symmetry of the cubic MgCu4Sn-type structure. We infer a moment of 4.6 mu_B on Mn at 17 K, which is oriented ferromagnetically along the {101} plane. The amplitude of the Mn vibrational motion is found to be larger than that of Ce and Ni atoms at all temperatures, thereby lending support to theoretical prediction of rattling phonon modes in this compound.

The Standard Model as a 2T-physics Theory

description: New developments in 2T-physics, that connect 2T-physics field theory directly to the real world, are reported in this talk. An action is proposed in field theory in 4+2 dimensions which correctly reproduces the Standard Model (SM) in 3+1 dimensions (and no junk). Everything that is known to work in the SM still works in the emergent 3+1 theory, but some of the problems of the SM get resolved. The resolution is due to new restrictions on interactions inherited from 4+2 dimensions that lead to some interesting physics and new points of view not discussed before in 3+1 dimensions. In particular the strong CP violation problem is resolved without an axion, and the electro-weak symmetry breakdown that generates masses requires the participation of the dilaton, thus relating the electro-weak phase transition to other phase transitions (such as evolution of the universe, vacuum selection in string theory, etc.) that also require the participation of the dilaton. The underlying principle of 2T-physics is the local symmetry Sp(2,R) under which position and momentum become indistinguishable at any instant. This principle inevitably leads to deep consequences, one of which is the two-time structure of spacetime in which ordinary 1-time spacetime is embedded. The proposed action for the Standard Model in 4+2 dimensions follows from new gauge symmetries in field theory related to the fundamental principles of Sp(2,R). These gauge symmetries thin out the degrees of freedom from 4+2 to 3+1 dimensions without any Kaluza-Klein modes.

description: If gaugino condensations occur in the early universe, domain walls are produced as a result of the spontaneous breaking of a discrete R symmetry. Those domain walls eventually annihilate with one another, producing the gravitational waves. We show that the gravitational waves can be a probe for measuring the gravitino mass, if the constant term in the superpotential is the relevant source of the discrete R symmetry breaking.

description: This work proposes a continuum-based approach for the propagation of uncertainties in the initial conditions and parameters for the analysis and prediction of spacecraft re-entries. Using the continuity equation together with the re-entry dynamics, the joint probability distribution of the uncertainties is propagated in time for specific sampled points. At each time instant, the joint probability distribution function is then reconstructed from the scattered data using a gradient-enhanced linear interpolation based on a simplicial representation of the state space. Uncertainties in the initial conditions at re-entry and in the ballistic coefficient for three representative test cases are considered: a three-state and a six-state steep Earth re-entry and a six-state unguided lifting entry at Mars. The paper shows the comparison of the proposed method with Monte Carlo based techniques in terms of quality of the obtained marginal distributions and runtime as a function of the number of samples used.

description: As the commercial use of 5G technologies has grown more prevalent, smart vehicles have become an efficient platform for delivering a wide array of services directly to customers. The vehicular crowdsourcing service (VCS), for example, can provide immediate and timely feedback to the user regarding real-time transportation information. However, different sources can generate spurious information towards a specific service request in the pursuit of profit. Distinguishing trusted information from numerous sources is the key to a reliable VCS platform. This paper proposes a solution to this problem called "RC-chain", a reputation-based crowdsourcing framework built on a blockchain platform (Hyperledger Fabric). We first establish the blockchain-based platform to support the management of crowdsourcing trading and user-reputation evaluating activities. A reputation model, the Trust Propagation \& Feedback Similarity (TPFS), then calculates the reputation values of participants and reveals any malicious behavior accordingly. Finally, queueing theory is used to evaluate the blockchain-based platform and optimize the system performance. The proposed framework was deployed on the IBM Hyperledger Fabric platform to observe its real-world running time, effectiveness, and overall performance.
