description: Increasingly, people will be in situations where there are multiple communicating computing devices that have input / output capabilities. For example, people might carry their handheld computer, such as a Windows CE device or a Palm Pilot, into a room with a desktop or an embedded computer. The handheld computer can communicate with the PC using wired or wireless technologies, and then both computers can be used at the same time. We are investigating many ways in which the handheld computer can be used to extend the functions of existing and new applications. For example, the handheld’s screen can be used as a customizable input and output device, to provide various controls for desktop applications. The handheld can contain scroll bars, buttons, virtual knobs and menus. It can also display the slide notes or a list of slide titles for a presentation, the list of current tasks and windows, and lists of links for web browsing. The user can tap on these lists on the handheld to control the PC. Information and control can be flow fluidly among all the user’s devices, so that there is an integrated environment.
Asymptotic behavior of the conductance in disordered wires with perfectly conducting channels
Creators: name: Takane, Yositake
Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We study the conductance of disordered wires with unitary symmetry focusing on the case in which $m$ perfectly conducting channels are present due to the channel-number imbalance between two-propagating directions. Using the exact solution of the Dorokhov-Mello-Pereyra-Kumar (DMPK) equation for transmission eigenvalues, we obtain the average and second moment of the conductance in the long-wire regime. For comparison, we employ the three-edge Chalker-Coddington model as the simplest example of channel-number-imbalanced systems with $m = 1$, and obtain the average and second moment of the conductance by using a supersymmetry approach. We show that the result for the Chalker-Coddington model is identical to that obtained from the DMPK equation.

description: Project Argus is focused on helping an analyst explore massive, structured data. This exploration includes exact and partial match queries, monitoring hypotheses and discovery of new patterns in both static and streaming data. We provide these facilities within the context of a workbench interface, called Data Explorer. We support exploration of data that is a collection of records, each of which is structured as several distinct fields. For instance, financial transfers are typically represented as structured records, with such fields as sending bank, sending account number, currency, amount, date, receiving account, etc. Most fields are well-defined, like a date, a dollar amount, or the receiving bank. Other fields may be longer and of more free-form content, like the body of an email message. In Argus, we have focused exclusively on the well-defined, structured data. As previously reported, we have been working on methods to retrieve such data flexibly to accommodate the lack of integrity and consistency in real-world data, to monitor it for watch patterns, and to identify novel and emerging trends as it accumulates over time.

description: Complex systems and relational data are often abstracted as dynamical processes on networks. To understand, predict and control their behavior, a crucial step is to extract reduced descriptions of such networks. Inspired by notions from Control Theory, we propose a time-dependent dynamical similarity measure between nodes, which quantifies the effect a node-input has on the network. This dynamical similarity induces an embedding that can be employed for several analysis tasks. Here we focus on (i)~dimensionality reduction, i.e., projecting nodes onto a low dimensional space that captures dynamic similarity at different time scales, and (ii)~how to exploit our embeddings to uncover functional modules. We exemplify our ideas through case studies focusing on directed networks without strong connectivity, and signed networks. We further highlight how certain ideas from community detection can be generalized and linked to Control Theory, by using the here developed dynamical perspective.

Families of Quantum Fingerprinting Protocols
Creators: name: Lovitz, Benjamin

Publisher: name: arXiv
Year: 2017
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We introduce several families of quantum fingerprinting protocols to evaluate the equality function on two $n$-bit strings in the simultaneous message passing model. The original quantum fingerprinting protocol uses a tensor product of a small number of $\mathcal{O}(\log n)$-qubit high dimensional signals [Buhrman et al. 2001], whereas a recently-proposed optical protocol uses a tensor product of $\mathcal{O}(n)$ single-qubit signals, while maintaining the $\mathcal{O}(\log n)$ information leakage of the original protocol [Arrazola and Lütkenhaus 2014]. We find a family of protocols which interpolate between the original and optical protocols while maintaining the $\mathcal{O}(\log n)$ information leakage, thus demonstrating a trade-off between the number of signals sent and the dimension of each signal. There has been interest in experimental realization of the recently-proposed optical protocol using coherent states [Xu et al. 2015, Guan et al. 2016], but as the required number of laser pulses grows linearly with the input size $n$, eventual challenges for the long-time stability of experimental set-ups arise. We find a coherent state protocol which reduces the number of signals by a factor $1/2$ while also reducing the information leakage. Our reduction makes use of a simple modulation scheme in optical phase space, and we find that more complex modulation schemes are not advantageous. Using a similar technique, we improve a recently-proposed coherent state protocol for evaluating the Euclidean distance between two real unit vectors [Kumar et al. 2017] by reducing the number of signals by a factor $1/2$ and also reducing the information leakage.

description: We study the origin and bifurcations of typical classes of unstable periodic orbits in a jet flow that was introduced before as a kinematic model of chaotic advection, transport and mixing of passive scalars in meandering oceanic and atmospheric currents. A method to detect and locate the unstable periodic orbits and classify them by the origin and bifurcations is developed. We consider in detail period-1 and period-4 orbits playing an important role in chaotic advection. We introduce five classes of period-4 orbits: western and eastern ballistic ones, whose origin is associated with ballistic resonances of the fourth order, rotational ones, associated with rotational resonances of the second and fourth orders, and rotational-ballistic ones associated with a rotational-ballistic resonance. It is a new kind of nonlinear resonances that may occur in chaotic flow with jets and/or circulation cells. Varying the perturbation amplitude, we track out the origin and bifurcations of the orbits for each class.

description: Using subresultants, we modify a recent real-algebraic proof due to Eisermann of the Fundamental Theorem of Algebra ([FTA]) to obtain the following quantitative information: in order to prove the [FTA] for polynomials of degree $d$, the Intermediate Value Theorem ([IVT]) is requested to hold for real polynomials of degree at most $d^2$. We also explain that the classical proof due to Laplace requires [IVT] for real polynomials of exponential degree. These quantitative results highlight the difference in nature of these two proofs.

description: The dominant method of energy loss by a loop of cosmic D-strings in models of warped brane inflation is studied. It is shown that the energy loss via Ramond-Ramond field radiation can dominate by many orders of magnitude over the energy radiation via gravitational wave emission. The ratio of these two energy loss mechanisms depends on the energy scale of inflation, the mass scale of string theory and whether it is a single-throat or a multi-throat inflationary scenario. This can have important consequences for the detection of cosmic superstrings in the near future. It is argued that the bounds from cosmic microwave background anisotropies and big bang nucleosynthesis are the dominant cosmological sources to constrain the physical parameters of the network of cosmic superstrings, whereas the role of the gravitational wave-based experiments may be secondary.

description: We describe a framework for interactive molecular dynamics in a multiuser virtual reality environment, combining rigorous cloud-mounted physical atomistic simulation with commodity virtual reality hardware, which we have made accessible to readers (see isci.itch.io/nsb-imd). It allows users to visualize and sample, with atomic-level precision, the structures and dynamics of complex molecular structures 'on the fly', and to interact with other users in the same virtual environment. A series of controlled studies, wherein participants were tasked with a range of molecular manipulation goals (threading methane through a nanotube, changing helical screw-sense, and tying a protein knot), quantitatively demonstrate that users within the interactive VR environment can complete sophisticated molecular modelling tasks more quickly than they can using conventional interfaces, especially for molecular pathways and structural transitions whose conformational choreographies are intrinsically 3d. This framework should accelerate progress in nanoscale molecular engineering areas such as drug development, synthetic biology, and catalyst design. More broadly, our findings highlight VR's potential in scientific domains where 3d dynamics matter, spanning research and education.

description: In this work, we study an optimal control problem for a multi-agent system modeled by an undirected formation graph with nodes describing the kinematics of each agent, given by a left-invariant control system on a Lie group. The agents should avoid collision between them in the workspace. Such a task is done by introducing some potential functions into the cost function for the optimal control problem, corresponding to fictitious forces, induced by the formation constraint among agents, that break the symmetry of the individual agents and the cost functions, and rendering the optimal control problem partially invariant by a Lie group of symmetries. Reduced necessary conditions for the existence of normal extremals are obtained using techniques of variational calculus on manifolds. As an application, we study an optimal control problem for multiple unicycles.

Damping of Condensate Oscillation of a Trapped Bose Gas in a One-Dimensional Optical Lattice at Finite Temperatures

Subjects: subject: Other Condensed Matter (cond-mat.other)

description: We study damping of a dipole oscillation in a Bose-Condensed gas in a combined cigar-shaped harmonic trap and one-dimensional (1D) optical lattice potential at finite temperatures. In order to include the effect of thermal excitations in the radial direction, we derive a quasi-1D model of the Gross-Pitaeavskii equation and the Bogoliubov equations. We use the Popov approximation to calculate the temperature dependence of the condensate fraction with varying lattice depth. We then calculate the Landau damping rate of a dipole oscillation as a function of the lattice depth and temperature. The damping rate increases with increasing lattice depth, which is consistent with experimental observations. The magnitude of the damping rate is in reasonable agreement with experimental data. We also find that the damping rate has a strong temperature dependence, showing a sharp increase with increasing temperature. Finally, we emphasize the importance of the radial thermal excitations in both equilibrium properties and the Landau damping.

Using CFT data previously obtained from the supersymmetric localization method, we carry out this procedure explicitly to the second nontrivial order in the momentum expansion, and recover precisely the known $R^4$ contribution to the scattering amplitude of super-gravitons in M-theory in eleven dimensions.

description: In this paper, we address the problem of how many randomly labeled patterns can be correctly classified by a single-layer perceptron when the patterns are correlated with each other. In order to solve this problem, two analytical schemes are developed based on the replica method and Thouless-Anderson-Palmer (TAP) approach by utilizing an integral formula concerning random rectangular matrices. The validity and relevance of the developed methodologies are shown for one known result and two example problems. A message-passing algorithm to perform the TAP scheme is also presented.

description: This paper presents strategies for reducing the impact force resulting from the collision of a kinematically redundant manipulator with an object in its environment. The Premultiplier Diagram, a tool used to derive the impact force reduction strategies presented in this paper, is introduced and discussed. Two strategies for reducing impact force are then presented. The first strategy involves adding torques to the joints of the redundant manipulator to impede motion into the object with which it collides. The second strategy involves choosing the best configuration for the impact event. Simulated results from the testing of either strategy are presented and discussed.

description: By using a 60 T magnetic field to suppress superconductivity in La2-pSrpCuO4, (LSCO) we reveal an anomalous peak in the Hall number, located at optimum doping and developing at temperatures below the zero-field superconducting transition temperature, Tc. The anomaly bears a striking resemblance to observations in Bi2Sr2-xLaxCuO6+delta (BSLCO) [F. F. Balakirev et al., Nature (London) 424, 912 (2003)], suggesting a normal state phenomenology common to the cuprates that underlies the high-temperature superconducting phase. The peak is ascribed to the transformation of the "Fermi arcs" into a conventional FS, the signature of a Fermi surface reconstruction associated with a quantum phase transition (QPT) near optimum doping and co-incident with the collapse of the pseudogap state.

description: The large-scale structure associated with the 2′N HNCO peak in Sgr B2 [Minh, Y.C., Haikala, L., Hjalmarson, Å., Irvine, W.M., 1998. ApJ 498, 261 (Paper I)] has been investigated. A ring-like morphology of the HNCO emission has been found; this structure may be colliding with the Principal Cloud of Sgr B2. This “HNCO Ring” appears to be centered at (l,b) = (0.7°,−0.07°), with a radius of 5 pc and a total mass of 1.0 × 105 to 1.6 × 106 M. The expansion velocity of the Ring is estimated to be 30–40 km s−1, which gives an expansion time scale of 1.5 × 105 year. The morphology suggests that collision between the Ring and the Principal Cloud may be triggering the massive star formation in the Sgr B2 cloud sequentially, with the latest star formation taking place at the 2′N position. The chemistry related to HNCO is not certain yet, but if it forms mainly via reaction with the evaporated OCN− from icy grain mantles, the observed enhancement of the HNCO abundance can be understood as resulting from shocks associated with the collision between the Principal Cloud and the expanding HNCO Ring.

description: To explore the function of VIG-1 in Caenorhabditis elegans, we analyzed the phenotypes of two vig-1 deletion mutants: vig-1(tm3383) and vig-1(ok2536). Both vig-1 mutants exhibited phenotypes associated with genome instability, such as a high incidence of males (Him) and increased embryonic lethality. These phenotypes became more evident in succeeding generations, implying that the germline of vig-1 accumulates DNA damage over generations. To examine whether vig-1 causes a defect in the DNA damage response, we treated worms with UV or camptothecin, a specific topoisomerase I inhibitor. We observed that the embryonic survival of the vig-1 mutants was reduced compared with that of the wild-type worms. Our results thus suggest that VIG-1 is required for maintaining genome stability in response to endogenous and exogenous genotoxic stresses.

description: Experimental data on the structure of ferroelectric oxide Bismuth Titanate suggests two different kinds of structures i.e. orthorhombic and monoclinic. We have performed density functional theory (DFT) based first principle calculations to determine the ground state structure of bismuth titanate, based on experimentally observed monoclinic and orthorhombic phases of Bi4Ti3O12. Both of these phases are optimized to zero pressure and lattice parameters were determined as a = 5.4370 Ang, b = 5.4260 Ang, c = 32.6833 Ang and Z = 4 for structure with space group B2cb and a = 5.4289 Ang, b = 5.4077 Ang, c = 32.8762 Ang, b = 90.08 deg and Z = 4 for the structure with space group B1a1 . Static and dynamic calculations show that the monoclinic structure with the space group B1a1 is the ground state structure. It is noted that small difference in the energies of both structures could be a factor behind experimental observation of either of the structure.

Publisher: name: Zenodo

description: Green innovation is essential for supporting economic transitions, restructuring the economy, and fostering sustainable, consistent growth. The adoption of growth methods driven by green innovation is primarily reliant on the technical developments produced by organisations. Green inclusive finance, a combination of conventional finance and digital technology, is crucial for the progress of technological innovation.  This article examines the field of green inclusive finance and the invention of green technology in enterprises. At first, a thorough analysis was conducted on three types of literature: green inclusive finance, green technology innovation, and the relationship between them. This article gives precise definitions for important topics such as green inclusive finance, green technological innovation, and financing restrictions by referring to relevant literature. Moreover, unlike other studies, this study considers the notion of financing restrictions when analysing the impact of green inclusive finance on business innovation. Additionally, it examines the role of finance limitations as an intermediary factor in this association.
Unitarity bounds in the Higgs model including triplet fields with custodial symmetry

description: We study bounds on Higgs boson masses from perturbative unitarity in the Georgi-Machacek model, whose Higgs sector is composed of a scalar isospin doublet, a real and a complex isospin triplet fields. This model can be compatible with the electroweak precision data without fine tuning because of the imposed global SU(2)_R symmetry in the Higgs potential, by which the electroweak rho parameter is unity at the tree level. All possible two-body elastic-scattering channels are taken into account to evaluate the S-wave amplitude matrix, and then the condition of perturbative unitarity is imposed on the eigenvalues to obtain constraint on the Higgs parameters. Masses of all scalar bosons turn out to be bounded from above, some of which receive more strict upper bounds as compared to that in the standard model (712 GeV). In particular, the upper bound of the lightest scalar boson, whatever it would be, is about 270 GeV.

description: The vector dominance of the electromagnetic form factors both for mesons and baryons arises naturally in holographic QCD, where both the number of colors and the 't Hooft coupling are taken to be very large, offering a bona-fide derivation of the notion of vector dominance. The crucial ingredient for this is the infinite tower of vector mesons in the approximations made which share features that are characteristic of the quenched approximation in lattice QCD. We approximate the infinite sum by contributions from the lowest four vector mesons of the tower which turn out to saturate the charge and magnetic moment sum rules within a few percent and compute them totally free of unknown parameters for momentum transfers Q^2 less than 1GeV^2. We identify certain observables that can be reliably computed within the approximations and others that are not, and discuss how the improvement of the latter can enable one to bring holographic QCD closer to QCD proper.

description: Deteriorations in soil quality and unreliability of rain-fed farming have caused tremendous reductions in yields of horticultural crops especially in low to middle income countries. This can  be solved through combined irrigation and fertilizer application using readily available resources in a process known as fertigation. Purpose: The study aimed at determining the most appropriate chicken manure-based drip fertigation regime for improved yield and quality of tomato and cabbage. Methodology: A three-replicate RCBD field experiment was set up at Makerere University Agricultural Research Institute, Kabanyolo characterized with sandy loam soils. Three treatments and two controls were set up and these included: 100% deep-litter manure (T1), 100% battery-cage manure (T2) and 50% battery-+ 50% deep-litter manure (T3), rainfed without fertigation (R) and water only (W). Liquid concentrations of the three manure treatments were extracted, characterized and applied to the crops. Weather and soil moisture conditions were monitored daily for irrigation scheduling. The fertigation schedule intended to provide the crops with net nutrient requirements. For each treatment data on crop growth parameters and yield were recorded. Proximate analysis for was done for crop physical-chemical quality parameters. A one-way ANOVA and Turkeys’ multiple comparison test conducted in R studio were used to test significance at 5% significance level.

Results: Results showed that crop growth parameters generally improved with increase in amount of nutrient in the treatments. For tomato, the highest total yield of 18.35±0.004 kg/m2 was realized with T2 followed T1, T3, W and R with 14.11±0.005 kg/m2, 13.82±0.0005 kg/m2, 11.85±0.004 kg/m2 and 9.89±0.004 kg/m2 respectively. Cabbage registered highest yield of 8.81±0.001 kg/m2 with T2 followed by T3, T1, W and R with 6.35±0.001 kg/m2, 5.88±0.001 kg/m2 3.37±0.001 kg/m2 and 1.49±0.001 kg/m2 respectively. Conclusion: Where available, battery cage is the most suitable composition for increased yield of tomato and cabbage due to the highest nutrient concentration of NPK content.

description: In using the logic of equality with unininterpreted functions to verify hardware systems, specific characteristics of the formula describing the correctness condition can be exploited when deciding its validity. We distinguish a class of terms we call “p-terms” for which equality comparisons can appear only in monotonically positive formulas. By applying suitable abstractions to the hardware model, we can express the functionality of data values and instruction addresses flowing through an instruction pipeline with p-terms. A decision procedure can exploit the restricted uses of p-terms by considering only “maximally diverse” interpretations of the associated function symbols, where every function application yields a different value except when constrained by functional consistency.We present a procedure that translates the original formula into one in propositional logic by interpreting the formula over a domain of fixed-length bit vectors and using vectors of propositional variables to encode domain variables. By exploiting maximal diversity, this procedure can greatly reduce the number of propositional variables that must be introduced. We present experimental results demonstrating the efficiency of this approach when verifying pipelined processors using the method proposed by Burch and Dill. Exploiting positive equality allows us to overcome the exponential blow-up experienced previously [VB98] when verifying microprocessors with load, store, and branch instructions.

description: Recently O. Pechenik studied the cyclic sieving of increasing tableaux of shape $2\times n$, and obtained a polynomial on the major index of these tableaux, which is a $q$-analogue of refined small Schröder numbers. We define row-increasing tableaux and study the major index and amajor index of row-increasing tableaux of shape $2 \times n$. The resulting polynomials are both $q$-analogues of refined large Schröder numbers. For both results we give bijective proofs.

description:  We study the applicability of the logic of Positive Equality with Uninterpreted Functions (PEUF) [2][3] to the verification of pipelined microprocessors with very large Instruction Set Architectures (ISAs). Abstraction of memory arrays and functional units is employed, while the control logic of the processors is kept intact from the original gate-level designs. PEUF is an extension of the logic of Equality with Uninterpreted Functions, introduced by Burch and Dill [4], that allows us to use distinct constants for the data operands and instruction addresses needed in the symbolic expression for the correctness criterion. We present several techniques that make PEUF scale very efficiently for the verification of pipelined microprocessors with large ISAs. These techniques are based on allowing a limited form of non-consistency in the uninterpreted functions, representing initial memory state and ALU behaviors. Our tool required less than 30 seconds of CPU time and 5 MB of memory to verify a 5-stage MIPS-like pipelined processor that implements 191 instructions of various classes. The verification was done by correspondence checking - a formal method, where a pipelined microprocessor is compared against a non-pipelined specification.

description: La diversité génétique est souvent considérée comme un facteur clé dans la capacité d’une espèce à s’adapter à des changements environnementaux. Un faible niveau de diversité génétique pourrait ainsi limiter la capacité de réponse évolutive d’une espèce à des perturbations à court et moyen terme. Or il existe une variabilité de diversité génétique entre espèces qui reste largement inconnue, et dont les déterminants naturels demeurent mal compris. L’objectif de cette étude est de comprendre quels sont les facteurs biologiques, écologiques et biogéographiques expliquant les différences de diversité génétique chez les poissons marins. En séquençant le génome complet de 160 poissons Atlantico-méditerranéens, des valeurs d'hétérozygotie ont été obtenues chez 113 espèces, révélant une amplitude de diversité génétique d’un facteur 12 entre espèces. Ces mesures ont ensuite permis de tester des corrélations entre valeurs de traits d’histoire de vie et diversité génétique des espèces. La diversité génétique s’est révélée être principalement corrélée à la taille du corps, l’âge à la maturité et le niveau de soins parentaux. Ces facteurs, qui semblent moduler la diversité génétique à travers des mécanismes évolutifs différents, illustrent la diversité des interactions éco-évolutives qui peuvent influencer le potentiel adaptatif des espèces.

description: The manipulator trajectory tracking control problem revolves around computing the torques to be applied to achieve accurate tracking. While this problem has been extensively studied in simulations, the real-time results have been lacking in the robotics literature. In this paper, we present the experimental results of the real-time performance of model-based control algorithms. We compare the computed-torque control scheme with the feedforward dynamics compensation scheme. The feedforward scheme compensates for the manipulator dynamics in the feedforward path while the computed-torque scheme uses the dynamics in the feedback loop for linearization and decoupling. The manipulator control schemes have been implemented on the CMU DD Arm 11 with a sampling period of 2 ms.
