DEGREE SEQUENCES OF MULTIGRAPHS

Abstract. Let a; b and n be integers, n 1 and b a 0. Letan (a;b;n)-graph de ned as a loopless graph G(a;b;n) on n verticesfV 1 ;:::;V n g, in which V i and V j are connected with at least a and at mostb (directed or undirected) edges. If G(a;b;n) is directed, then it is called(a;b;n)-digraph and if it is undirected, then it is called (a;b;n)-undigraph.Landau in 1953 published an algorithm deciding whether a nondecreasingsequence of nonnegative integers is the out-degree sequence of a (1;1;n)-digraph. Moon in 1963 published a similar condition for (b;b;n)-digraphs,and in 2009 Ivanyi did for (a;b;n)-digraphs. Havel in 1955, Erd}os andGallai in 1960 proposed an algorithm to decide the same question for(0;1;n)-undigraphs. Their theorem was extended to (0;b;n)-undigraphsby Chungphaisan in 1974. In 2011 Ozkan [24] proved a stronger version. The aim of this paper is to summarize and extend the known results andto propose quicker algorithms than the known ones. 1.

Improving the Speed of Kernel PCA on Large Scale Datasets

This paper concerns making large scale Kernel Principal Component Analysis (KPCA) feasible on regular hardware. The KPCA has been proven a useful non-linear feature extractor in several computer vision applications. The standard computation method for KPCA, however, scales badly with the problem size, thus limiting the potential of the technique for large scale data. We propose a novel method to alleviate this problem. The essence of our solution lies in partitioning the data and greedily filtering each partition for a sparse representation. Incremental KPCA is then utilized to merge each partition to arrive at the overall KPCA. We also provide experimental results which demonstrate the effectiveness of the approach.
Dengue Virus Ensures Its Fusion in Late Endosomes Using Compartment-Specific Lipids

Many enveloped viruses invade cells via endocytosis and use different environmental factors as triggers for virus-endosome fusion that delivers viral genome into cytosol. Intriguingly, dengue virus (DEN), the most prevalent mosquito-borne virus that infects up to 100 million people each year, fuses only in late endosomes, while activation of DEN protein fusogen glycoprotein E is triggered already at pH characteristic for early endosomes. Are there any cofactors that time DEN fusion to virion entry into late endosomes? Here we show that DEN utilizes bis(monoacylglycero)phosphate, a lipid specific to late endosomes, as a co-factor for its endosomal acidification-dependent fusion machinery. Effective virus fusion to plasma- and intracellular- membranes, as well as to protein-free liposomes, requires the target membrane to contain anionic lipids such as bis(monoacylglycero)phosphate and phosphatidylserine. Anionic lipids act downstream of low-pH-dependent fusion stages and promote the advance from the earliest hemifusion intermediates to the fusion pore opening. To reach anionic lipid-enriched late endosomes, DEN travels through acidified early endosomes, but we found that low pH-dependent loss of fusogenic properties of DEN is relatively slow in the presence of anionic lipid-free target membranes. We propose that anionic lipid-dependence of DEN fusion machinery protects it against premature irreversible restructuring and inactivation and ensures viral fusion in late endosomes, where the virus encounters anionic lipids for the first time during entry. Currently there are neither vaccines nor effective therapies for DEN, and the essential role of the newly identified DEN-bis(monoacylglycero)phosphate interactions in viral genome escape from the endosome suggests a novel target for drug design.
Cognitive Multi-Channel MAC Protocols with Perfect and Imperfect Sensing

Analytical formulations of the throughput of cognitive multi-channel MACs with perfect and imperfect sensing are presented. Both imperfect concurrent sensing and imperfect sequential sensing schemes are considered. A discrete time Markov chain is used to model the number of communicating node pairs in the MAC protocols. The throughput of the MAC protocol with perfect sensing is expressed as a function of the number of available data channels, the channel transmission rate, the average utilization per channel, the steady state probability of having a number of available data channels, while the throughput of the MAC protocol with imperfect sensing is expressed as a function of the number of available data channels, the channel transmission rate, the average utilization per channel, the steady state probability of having a number of available data channels, probability of false alarm and probability of misdetection. The results also clearly demonstrate the advantage of our proposed MAC protocol with imperfect concurrent sensing having low probability of misdetection but high probability of false alarm.
CGV – Coordinated Graph Visualization

Visualizing large hierarchized graphs is such a challenging task that it is hardly possible to represent all relevant information within a single comprehensible image. To address that challenge, we pursue multiple linked view visualization. We report on a visualization framework for exploring hierarchized graphs that focusses on a modular architecture based on the model-view-controller (MVC) concept. MVC helps us in coordinating views as users explore and navigate the data. Several interaction facilities further support users in applying the framework for their data and their task at hand.
The Moderation of Output and In‡ation: A Good Shock, Bad Shock Story

We allow jointly for money and credit shocks to eect output through an endogenous growth business cycle model that includes ex- change credit. For the 1919-2004 annual period, we explain the close correlation of volatilities of GDP growth and in‡ation in terms of credit and money shocks that have "bad" and "good" eects, de…ned in terms of their eects on the spectral variation in GDP. With these shocks we characterize and contrast the two great volatility cycles over this historical period. The Great Moderation post-1983 coincided with good credit shocks from deregulation, while the Great Depression was faced with bad money and credit shocks that were consistent with its prolonged nature.
Tracking control of wheeled mobile robots with a single steering input - control using reference time-scaling

This paper presents a time-scaling based control strategy of the kinematic model of wheeled mobile robots with one input which is the steering angle. The longitudinal velocity of the mobile robot cannot be influenced by the controller but can be measured. Using an on-line time-scaling, driven by the longitudinal velocity of the robot and its time derivatives, one can achieve exponential tracking of any sufficiently smooth reference trajectory with non-vanishing velocity. The price to pay is the modification of the traveling time along the reference trajectory according to the time-scaling. The measurement of the time derivatives of the velocity is no longer necessary if the tracking controller is designed to the linearized tracking error dynamics.
Designing Bang-Bang PLLs for Clock and Data Recovery in Serial Data Transmission Systems

Clock recovery using phase-locked loops (PLL) with binary (bang-bang) or ternary-quantized phase detectors has become increasingly common starting with the advent of fully monolithic clock and data recovery (CDR) Circuits in the late 1980's. Bang-bang CDR circuits have the unique advantages of inherent sampling phase alignment, adaptability to multi-phase sampling structures, and operation at the highest speed at which a process can make a working flip-flop. This paper gives insight into the behavior of the nonlinear bang-bang PLL loop dynamics, giving approximate equations for loop jitter, recovered clock spectrum, and jitter tracking performance as a function of various design parameters. A novel analysis shows that the bang-bang loop output jitter grows as the square-root of the input jitter as contrasted with the linear dependence of the linear PLL.
A Method for Filtering the Blocking Artifacts in Block Coded JPEG Images

The popular international standard for compression, the Joint Photographers Expert Group (JPEG) can lead to noticeable discontinuities along the boundaries called the ‘blocking artifacts’. When the image is JPEG compressed the high frequency details of the coded image are mainly contaminated by quantization noise. The effect of quantization noise in the image can be approximated to that of Gaussian noise. The filter proposed in this paper preserve the details whereas the artifacts are smoothened. Keywords— Blocking artifact, JPEG, Post processing, Image Enhancement.
Four olive branches: What the FERC bestowed on PUCs in Order 888

Where others see conflict, a Pennsylvania commissioner finds a peace offering, not a grab for power. The jurisdictional issues posed by Order 888 continue to breed tension between federal and state officials. Unfortunately, most of this tension too often elevates form over substance. This jurisdictional tension shifts the focus of decisionmaking from securing the benefits of competition to preserving regulatory turf. In Order 888, the Federal Energy Regulatory Commission (FERC) extends four important olive branches to those states that want to introduce customer choice at the retail level. While these olive branches are not a fundamental concession by the FERC, state officials should pursue them before attacking Order 888 for its broad claims over jurisdiction.
Data-Driven Modeling and Control of an Autonomous Race Car

This paper explores the application of machine learning techniques to the modeling and control of a race car. Regression models are used to simulate the vehicle’s dynamics more accurately than traditional physics-based models, and we achieve the best generalization performance with bootstrapaggregated regression trees. We incorporate this simulation model into an approximate dynamic programming framework that attempts to outperform a professional human driver. We demonstrate successful application of this approach on a 480-meter segment of a racetrack.
A girl with neurofibromatosis type 1, atypical autism and mosaic ring chromosome 17

We describe a girl with neurofibromatosis type 1 (NF1), mild dysmorphic features, growth and mental retardation, autism, and mosaicism of ring chromosome 17 and chromosome 17 monosomy. The extent of genetic material deleted from the ring chromosome was determined using a combination of classical cytogenetics, fluorescence in situ hybridization (FISH) and multiplex ligation‐dependent probe amplification (MLPA) to be 0.6–2.5 Mb on 17p, and up to about 10 Mb on 17q. Based on our observations and on a review of the literature we argue that in addition to a universal “ring syndrome” which is based on ring instability and is less specific for the chromosome involved, various ring chromosomes underlie their own characteristic phenotypes. We propose that the symptoms leading to the diagnosis of NF1 in our patient could be attributed to mosaic hemizygosity for the NF1 gene in some of her somatic cells. A similar mechanism or a direct involvement of respective disease genes in the aberration could possibly influence also the development of autism and other symptoms. We raise a question if the loss of one copy of chromosome 17 from a substantial fraction of somatic cells can have specific consequences also for future risks of the patient, for example, due to the mosaic hemizygosity for the BRCA1 and TP53 genes. © 2006 Wiley‐Liss, Inc.
Multiwavelength Picture of the Blazar S5 0716+714 during Its Brightest Outburst

S5 0716+714 is a well known BL Lac object, and one of the brightest and most active blazars. The discovery in the Very High Energy band (VHE, E > 100 GeV) by MAGIC happened in 2008. In January 2015, the source went through the brightest optical state ever observed, triggering MAGIC follow-up and a VHE detection with ∼ 13 σ significance (ATel ♯ 6999 ). Rich multiwavelength coverage of the flare allowed us to construct the broad-band spectral energy distribution of S5 0716+714 during its brightest outburst. In this work, we will present the preliminary analysis of MAGIC and Fermi-LAT data of the flaring activity in January and February 2015 for the HE (0.1 < HE < 300 GeV) and VHE band, together with radio (Metsahovi, OVRO, VLBA, Effelsberg), sub-millimeter (SMA), optical (Tuorla, Perkins, Steward, AZT-8+ST7, LX-200, Kanata), X-ray and UV (Swift-XRT and UVOT), in the same time-window and discuss the time variability of the multiwavelength light curves during this impressive outburst.
World Wide Web Consortium

Disclosed is a label or patch overlay dispensing apparatus having a storage reel for carrying a supply tape of adhesive overlays, a feed throat for receiving a document to which an overlay is to be attached and a contact for sensing a document in the feed throat and for causing the advancement of the document to a label attaching position. The device is responsive to the receipt of the document in the overlay attaching position for releasing an overlay or patch for attachment to the document and a pressure bonder for attaching the label is activated when the overlay is removed from the supply roll. As the overlay is attached the document is concurrently ejected from the device.

Exploring the Loneliness and Internet Addiction Level of College Students Based on Demographic Variables

The aim of this study is to examine the loneliness and Internet addiction levels of college students in terms of demographic variables and to determine the variables that predict their Internet addiction level. Data were collected from college students studying at a public university in Turkey. The UCLA Loneliness Scale Version3 and Internet Addiction Test (IAT) were used as the data collection tools. College students were delivered an online survey and at the end 489 college students were voluntarily participated in the study. This survey study employed independent sample t-tests, ANOVA tests, correlation and multiple regression tests for data analysis. The results show that younger participants felt significantly more loneliness than older participants; similarly, students in lower classes felt more alone than those in upper classes. In terms of addiction, it is seen that the frequent use of computers, smartphones and social media increases the Internet addiction level of students. The study suggests a significant correlation between loneliness, Internet addiction, age, and Cumulative Grade Point Average (CGPA). Additionally, loneliness and CGPA significantly predict Internet addiction. This study may be important in terms of determining the psychological variables affecting today's increasing technology addiction (internet, smart phone, etc.). Thus, determining the effect of the level of loneliness of young people on internet addiction may be effective in terms of preventing this addiction.
Lightweight Self-Bootstrapping Multiparty Computations of Time-Series Data with Custom Collusion Tolerance

In this work we compare two recent multiparty computation (MPC) protocols for private summation in terms of performance. Both protocols allow multiple rounds of aggregation from the same set of public keys generated by parties in an initial stage. We instantiate the protocols with a fast elliptic curve and provide an experimental comparison of their performance for different phases of the protocol. Furthermore, we introduce a technique that allows the computational load of both protocols to be reduced at the expense of protection against collusion tolerance. We prove that both protocols remain secure with this technique, and evaluate its impact on collusion tolerance and the number of rounds supported.
A practical detection of non-cooperative satellite based on ellipse fitting

As some of the valuable satellites can maintain working after on-orbit servicing, it's meaningful to study on the autonomous rendezvous. Most of these satellites are non-cooperative, more specifically, they have no target location markers or rendezvous sensors. This paper extracts the edge of the adapter ring as natures for recognition, measurement or even mechanical docking. A practical detection method of non-cooperative satellite based on ellipse fitting is proposed in this paper. By detecting the contours of the input image, we can estimate the ellipse parameters at the curve level. Linear segmentation method is used to extract straight-line segments from edge contours. After that, we construct a graph model to segment each line contour into elliptical arcs of a possible ellipse. Finally, ellipse detection based on least square algorithm is used to get the expression of the quadric curve in the pixel coordinate system of the image. The corresponding algorithm is experimented on the image in all directions with complex backgrounds, it can provide a real-time result with high accuracy compared with conventional methodologies.
MedTxting: Learning based and Knowledge Rich SMS-style Medical Text Contraction

In mobile health (M-health), Short Message Service (SMS) has shown to improve disease related self-management and health service outcomes, leading to enhanced patient care. However, the hard limit on character size for each message limits the full value of exploring SMS communication in health care practices. To overcome this problem and improve the efficiency of clinical workflow, we developed an innovative system, MedTxting (available at http://medtxting.askhermes.org), which is a learning-based but knowledge-rich system that compresses medical texts in a SMS style. Evaluations on clinical questions and discharge summary narratives show that MedTxting can effectively compress medical texts with reasonable readability and noticeable size reduction. Findings in this work reveal potentials of MedTxting to the clinical settings, allowing for real-time and cost-effective communication, such as patient condition reporting, medication consulting, physicians connecting to share expertise to improve point of care.
Informativeness, relevance and scalar implicature

1. Introduction The main topic of this paper is the phenomenon of scalar implicature. Typical examples are given in (1)-(4): (1) a. Bill has got some of Chomsky's papers. b. The speaker believes that Bill hasn't got all of Chomsky's papers. (2) a. There will be five of us for dinner tonight. b. There won't be more than five of us for dinner tonight. (3) a. X: I like Mary. She's intelligent and good-hearted. Y: She's intelligent. b. Y doesn't think Mary is good-hearted. (4) a. She won't necessarily get the job. b. She will possibly get the job. The idea is that, in a wide range of contexts, utterances of the sentences in (a) in each case will communicate the assumption in (b) in each case (or something closely akin to it, there being a certain amount of contextually governed variation in the speaker's propositional attitude and so the scope of the negation). These scalar inferences are taken to be one kind of (generalized) conversational implicature. As is the case with pragmatic inference quite generally, these inferences are defeasible (cancellable), which distinguishes them from entailments, and they are nondetachable, which distinguishes them from conventional implicatures. The core idea is that the choice of a weaker element from a scale of elements ordered in terms of semantic strength (that is, numbers of entailments) tends to implicate that, as far as the speaker knows, none of the stronger elements in the scale holds in this instance. The pattern is quite clear in (1) and (2), where the weak/strong alternatives are some/all and five/six respectively. In the case of (3), the stronger expression must be intelligent and good-hearted which entails intelligent; what Y's utterance implicates is that Mary does not have the two properties: intelligence and good-heartedness, so that, given the proposition expressed (Mary is intelligent) it follows, deductively, that she is not good-hearted, in Y's opinion. The example in (4) involves a scale inversion due to the negation, so that the weak/strong alternatives are not necessarily/not possibly; the negation which the scalar inference generates creates a double negation, which is eliminated giving possibly. Accounting for these sorts of examples, and more complicated scalar cases, has been, and still is, a central concern in neo-Gricean pragmatics (see references to Horn, Gazdar, Levinson, Hirschberg, Matsumoto, Welker, van Kuppevelt), but it has received relatively little attention in relevance-theoretic pragmatics. However, in the recent Postface …
Hybrid underwater optical/acoustic link design

The performance of duplex underwater optical wireless communication systems are limited by back-scattering of the transmitted light. This paper introduces a novel underwater wireless link design using hybrid optical/acoustic as a method to overcome it. The design comprises of highly directive, high-bandwidth optical uplinks from submersed AUVs or divers to a base station and a low bandwidth, wide-angle downlink. The limiting performance factors for the acoustic and optical aspects were found through respective channel modelling and SNRs; the maximum bitrate of the hybrid link is greater than a traditional acoustic link by a factor of 150. Main issues such as susceptibility to natural ocean variation, optical misalignment and acoustic latency are discussed.
Evaluation of Peripheral Displays

— There are many treatises on the evaluation of devices that make information of any kind available. However the evaluation of peripheral displays turns out to be difficult as their users do not interact with them directly. Most of the evaluations done on this topic concentrate on the results of the evaluation for producers and designers of peripheral displays. This paper proves that the fundamental attitude of the user towards this kind of display must be a part of the evaluation. As neither possible users nor possible evaluators have a lot of experience with these displays the preconceptions of the people involved are more important for this kind of evaluation than for traditional displays. These preconceptions have a direct influence on the results of the evaluation.
A divertent generating function that can be summed and analysed analytically

We study a recurrence relation, originating in combinatorial problems, where the generating function, as a formal power series, satisfies a differential equation that can be solved in a suitable domain; this yields an analytic function in a domain, but the solution is singular at the origin and the generating function has radius of convergence 0. Nevertheless, the solution to the recurrence can be obtained from the analytic solution by finding an asymptotic series expansion. Conversely, the analytic solution can be obtained by summing the generating function by the Borel summation method. This is an explicit example, which we study detail, of a behaviour known to be typical for a large class of holonomic functions. We also express the solution using Bessel functions and Lommel polynomials.
