Characterising the Difference and the Norm between Sequence Databases

In pattern set mining we are after a small set of patterns that together are characteristic for the data at hand. In this paper we consider the problem of characterizing not one, but a set of sequence databases, such as a collection of articles or the chapters of a book. Our main objective is to find a set of patterns that captures the individual features of each database, while also finding shared characteristics of any subset of the data we are interested in. We formulate this problem in terms of MDL, and propose SqsNorm, an e cient algorithm to extract high quality models directly from data. We devise a heuristic to quickly find and evaluate candidates, as well as a model that takes shared and singular patterns into account. Experiments on synthetic data confirm that SqsNorm ably reconstructs the ground truth model. Experiments on text data, including a set of speeches, several book chapters, and a collection of songs, show that SqsNorm discovers informative, non-redundant and easily interpretable pattern sets that give clear insight in the data.
QUADRATIC INTERACTION FUNCTIONAL FOR SYSTEMS OF CONSERVATION LAWS: A CASE STUDY

We prove a quadratic interaction estimate for wavefront approximate solutions to the tri- angular system of conservation laws ut + ~ f(u;v)x = 0; vt vx = 0: This quadratic estimate has been used in the literature to prove the convergence rate of the Glimm scheme (2). Our aim is to extend the analysis, done for scalar conservation laws (7), in the presence of transversal interactions among wavefronts of dierent families. The proof is based on the introduction of a quadratic functional Q(t), decreasing at every interaction, and such that its total variation in time is bounded. The study of this particular system is a key step in the proof of the quadratic interaction estimate for general systems: it requires a deep analysis of the wave structure of the solution (u(t;x);v(t;x)) and the reconstruction of the past history of each wavefront involved in an interaction.
Diatom composition of the rheoplankton in a rhithral river system

Abstract Diatom composition of the rheoplankton (phytoplankton) in the Sajó-Hernád river system (Slovakia and Hungary) was studied. Forty two sample sites were designated on the watershed from source to mouth of the two rivers and their tributaries. Samples were taken in July 2012. Altogether, 258 diatom taxa were identified. The microflora was dominated by tychoplanktonic elements. According to the relative abundance of the occurring taxa, four groups could be distinguished. Differentiation of these groups was confirmed by differences in the habitat characteristics, viz. altitude, width of watercourse, macrophyte coverage and river bed material. Diversity of diatom taxa in the phytoplankton was also studied. A positive relationship was found between the macrophyte coverage and the Simpson and the Shannon indices. In contrast, a negative relationship was shown between the macrophyte coverage and Berger-Parker diversity, in which metric the role of the dominant taxa is emphasized. Although the phytoplankton in rhithral rivers is influenced by stochastic events, our results reveal that geographical and hydromorphological characteristics of the rivers and coverage of macrophytes can also play role in shaping the composition and diversity of the phytoplankton.
On probability collectives for distributed control allocation

Stochastic optimization techniques by definition offer an element of randomness on the search trajectory for the best solution to an objective, and can be leveraged to gain confidence over traditional deterministic approaches. A novel method, Probability Collectives (PC) of Collective Intelligence (COIN), performs this type of stochastic search directly in the probability domain rather than in the variable domain, and enables a parallel processing architecture relevant to a distributed flight control system. Cooperating agents learn a local optimal strategy to minimize a global system cost. In this paper, we define these agents as individual aircraft effectors working to zero an acceleration error for the rigid body stability and control application. We present our initial acclimation to the PC framework with two forms of the method, delayed and immediate sampling, first in a simplified example setting with a two dimensional nonlinear objective, and finally in recent work for distributed control allocation of a hypothetical air vehicle with five effectors.
Are premature public health statements warranted?

Thank you for your response to our letter. We believe waterpipe tobacco (WT) smoking is an important public health issue and we would like to clarify several issues identified in your response. First, our letter was written to inform Australian public health workers about WT smoking. In our study population, Arabicspeaking adults residing in south-west Sydney, cigarette, cigar and/or pipe (CCP) smoking was strongly associated with waterpipe smoking (4.48, 95% CI 3.0 – 6.7). We did not make any statements of causality in our letter. However, considering this link between the behaviours, we hope that if we can reduce CCP smoking prevalence we may in turn reduce WT smoking. Furthermore, given the limited public health resources for interventions, the conclusive evidence of the harms of cigarette smoking, and that in our study population CCP smoking had more than double the prevalence of WT smoking (26% vs. 11.4%), CCP smoking should clearly remain the main priority for tobacco control interventions in this population. doi: 10.1111/j.1753-6405.2008. 00286.x
A portion of RNA polymerase II molecules has a component essential for stress responses and stress survival

Cells respond to stress by altering gene expression, and these adjustments facilitate stress tolerance. Although transcriptional changes are integral to most stress responses, little is known about the mechanisms that permit the transcription apparatus itself to tolerate stress. Here we report that a major role of the RNA polymerase II subunit RPB4 is to permit appropriate transcriptional responses during stress. Yeast cells lacking RPB4 have essentially wild-type growth rates at moderate temperatures (18 to 22 degrees C), but their growth rates are substantially reduced at temperatures outside this range. When subjected to a heat shock, cells lacking RPB4 rapidly lose the ability to transcribe genes and experience a dramatic loss in viability. When cells lacking RPB4 are subjected to the nutrient stress that accompanies entry into stationary phase, they also exhibit a substantial decline in mRNA synthesis and in viability relative to wild-type cells. Interestingly, the portion of RNA polymerase II molecules that contain RPB4 is small in log phase but increases substantially as cells enter stationary phase. We propose that the association of RPB4 with the other RNA polymerase II subunits increases the tolerance of the enzyme to stress.
An Efficient NIDS by using Hybrid Classifiers Decision Tree & Decision Rules

In the field of internet, network based application plays a vital role, where data transfers mostly in digital forms in various formats from source to destinations. In this digital exchange of information there are several possibilities of attacks and vulnerabilities. Intrusion detection systems are widely used to protect networks. An efficient detection of intrusion from network data set is a big problem which receives more attention from the various research communities. Various data mining classification techniques such as J-48 and SVM are widely used by researchers on various data sets such as KDD cup-99, NSL-KDD dataset. In this research paper we are presenting an efficient network intrusion detection system by using hybrid classifiers decision tree and decision rules for NSL-KDD dataset. An experimental study were performed by using weka-3-6 and MATLAB tool for existing J-48 and hybrid method and various performance improvement parameters such as precession, fmeasure, tprate and true positive rates are calculated.

Identification of gel‐separated proteins by liquid chromatography‐electrospray tandem mass spectrometry: Comparison of methods and their limitations

We have compared several different experimental systems currently in use in our laboratory for protein identification by high performance liquid chromatography–electrospray ionization tandem mass spectrometry (HPLC‐ESI‐MS/MS) after sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS‐PAGE). The efficiency of peptide recovery from trypsin‐digested gel bands or electroblotted membrane slices was examined using 35S‐labeled yeast proteins, and was found to be in excess of 80%. A dilution series of two standard proteins, bovine serum albumin (BSA) and carbonic anhydrase (CA), was analyzed by HPLC‐ESI‐MS/MS to determine what amount of protein could be loaded onto a gel and successfully identified, a measure we refer to as the practical detection limit. We were able to identify both standards at the 500 ng level in samples prepared from gel slices, using either a regular spray or a flow‐split microspray HPLC‐MS interface system. In samples prepared from membrane pieces, carbonic anhydrase was also identified at the 500 ng level, while bovine serum albumin could only be identified in samples of more than 1000 ng. In general, protein identification was slightly better in samples prepared from gels rather than membranes. A dilution series of lesser amounts of the same standard proteins was also analyzed using a gradient capillary LC system and we were able to successfully identify 50 ng of carbonic anhydrase and 100 ng of BSA.
Electromagnetic Coupling Reduction in High-Profile Monopole Antennas Using Single-Negative Magnetic Metamaterials for MIMO Applications

Single-negative magnetic metamaterials are used in order to reduce mutual coupling between high-profile antennas used in multiple-input multiple-output systems. The magnetic permeability of the developed single-negative inclusions have negative effective response over a specific frequency band. The inclusions considered here are composed of broadside coupled split-ring resonators. The single-negative magnetic inclusions are inserted between closely-spaced high-profile monopole antenna elements. It is shown that mutual coupling between the antenna elements can be reduced significantly by incorporating such magnetic inclusions. Effective response of the constitutive parameters of the developed magnetic inclusions are incorporated within the numerical models. Good agreement is obtained between the experimental and numerical results.
Use of an acoustic helium analyzer and microprocessor for rapid measurement of absolute lung volume during mechanical ventilation

A technique developed to measure functional residual capacity during mechanical ventilation uses an acoustic helium analyzer and microprocessor to perform open-circuit helium washout. The acoustic helium analyzer has acceptable linearity up to a helium concentration of 50% and is stable. The microprocessor combines output from the acoustic analyzer and a ventilator with an expiratory flow signal, to compute lung volume rapidly during mechanical ventilation. In a sample of ten patients with various lung problems, open-circuit helium washout gave results similar to those of a closed-circuit helium-dilution technique during assist control or intermittent mandatory ventilation modes, with or without positive end-expiratory pressure. This open-circuit system has an advantage over other techniques because it is small and portable and can measure lung volume quickly without complicated maneuvers.
Job factors and work outcomes of public sector expatriates

While the literature on private sector expatriates is burgeoning, research on public sector expatriates is scant, despite their increasing numbers. This is unfortunate, as these two groups of expatriates may face different work conditions at their foreign assignment. The target group for this study was the US Department of Defense administrators located at US embassies around the world. Results showed that the time expatriates had spent in their current location had a positive association with both work adjustment and work effectiveness. So did role clarity, which also had a positive association with job satisfaction, making it a more important job factor than role conflict, role overload or role discretion. Although role clarity may have a similar impact on work outcomes of expatriates, both in the private and public sector, the findings regarding role conflict and role overload may constitute a discrepant outcome for the two groups. There may also be a difference between the two categories of expatriates with regard to role discretion. Implications of these findings are discussed in detail.
Neonatal heart-rate response to tactile, auditory, and vestibular stimulation in different states.

POMERLEAU-MALCUIT, ANDREE, and CLIFTON, RACHEL K. Neonatal Heart-Rate Response to Tactile, Auditory, and Vestibular Stimulation in Different States. CHILD DEVELOPMENT, 1973, 44, 485-496. Newborn cardiac activity was analyzed in the context of the orienting response. Stimuli in 3 modalities were presented to Ss in different states: before and after a feeding, while sleeping and awake. Each S received 3 trials of tactile, vestibular, and auditory stimulation. Statistical analyses were performed on heart rate (HR) during each of the 10 seconds of stimulation. In sleeping Ss, the HR response was primarily accelerative to tactile and vestibular stimulation but unreliable to auditory stimulation. For the awake Ss, the feeding variable affected Ss' responsivity to auditory and vestibular stimuli. Before feeding, awake Ss decelerated to both types of stimuli. After feeding, there was no reliable response to any stimulus. A decelerative response was also found to vestibular stimulation in sleeping babies tested before feeding, but only when this type of stimulus was presented first in the sequence. In general, newborns tended to respond with less variability when tested before feeding. The newborn's cardiac response to stimuli in different modalities is affected by arousal state and feeding condition.
Feature Ensemble Network with Occlusion Disambiguation for Accurate Patch-Based Stereo Matching

Accurate stereo matching remains a challenging problem in case of weakly-textured areas, discontinuities and occlusions. In this letter, a novel stereo matching method, consisting of leveraging feature ensemble network to compute matching cost, error detection network to predict outliers and priority-based occlusion disambiguation for refinement, is presented. Experiments on the Middlebury benchmark demonstrate that the proposed method yields competitive results against the state-of-the-art algorithms. key words: stereo matching, convolutional neural network, patch-based, occlusion disambiguation
Chern insulator with large Chern numbers. Chiral Majorana fermion liquid

In the framework of Hofstadter’s approach we provide a detailed analysis of a realization of exotic topological states such as the Chern insulator (CI) with large Chern numbers. In a transverse homogeneous magnetic field a one-particle spectrum of fermions transforms to an intricate spectrum with a fine topological structure of the subbands. In a weak magnetic field H for a rational magnetic flux, a topological phase with a large Chern number is realized near the half filling. There is an abnormal behavior of the Hall conductance σ xy ≃ e 2 H . At half-filling, the number of chiral Majorana fermion edge states increases sharply forming a new state, called the chiral Majorana fermion liquid.
Analysis of Acoustic Wave in Homogeneous and Inhomogeneous Media Using Finite Element Method

Even though the propagation of elastic/acoustic waves in inhomogeneous and layered media has been an active research topic for many decades already, new problems and challenges continue to be posed even up to now. In fact, during the last few years, renewed interests have been witnessed by researchers in the various fields of acoustics, such as acoustic mirrors, filters, resonators, waveguides, and other kinds of acoustic devices, in relation to wave propagation in periodic elastic media. In acoustics and applied mechanics, these developments have been triggered by the need for new acoustic devices in order to obtain quality control of elastic/acoustic waves. What sort of material can allow us to have complete control over the elastic/acoustic wave’s propagation? We would like to discuss and answer this question in this chapter. It is well known that the successful applications of photonic band-gap materials have hastened the related researches on phononic band-gap materials. Analysis of Acoustic Wave in Homogeneous and Inhomogeneous Media Using Finite Element Method explores the theoretical road leading to the possible applications of phononic band gaps. It should quickly bring the elastic/acoustic professionals and engineers up to speed in this field of study where elastic/acoustic waves and solid-state physics meet. It will also provide an excellent overview to any course in elastic/acoustic media. Previous research on photonic crystals (Johnson & Joannopoulos, 2001, 2003; Joannopoulos et al., 1995; Leung & Liu, 1990) has sparked rapidly growing interest in the analogous acoustic effects of phononic crystals and periodic elastic structures. The various techniques for band structure calculations were introduced (Hussein, 2009). There are many wellknown methods of calculating the band structures of photonic and phononic crystals in addition to the reduced Bloch mode expansion method: the plane-wave expansion (PWE) method (Huang & Wu, 2005; Kushwaha et al., 1993; Laude et al., 2005; Tanaka & Tamura, 1998; Wu et al., 2004 ; Wu & Huang, 2004), the multiple-scattering theory (MST) (Leung & Qiu, 1993; Kafesaki & Economou, 1999; Psarobas & Stefanou, 2000; Wang et al., 1993), the finite-difference (FD) method (Garica-Pabloset et al., 2000; Sun & Wu, 2005; Yang, 1996), the transfer matrix method (Pendry & MacKinnon, 1992), the meshless method (Jun et al., 2003), the multiple multipole method (Moreno et al., 2002), the wavelet method (Checoury & Lourtioz, 2006; Yan & Wang, 2006), the pseudospectral method (Chiang et al., 2007), the finite element method (FEM) (Axmann & Kuchment, 1999; Dobson, 1999; Huang & Chen,
The Grammatical Factors Influencing the Choice between the Use and Omission of the Definite Article Preceding Multi-Word Organization Names: A Statistical Analysis

This article makes a first attempt to explore an empirical analysis of the intricate usage of the definite article preceding multi-word organization names. By making use of logistic regression, the present corpus-based study aims to construct a statistical model in an attempt to discern the grammatical factors that are hypothesized as influencing the choice between the use and omission of the definite article preceding organization names in relation to the principle of parsimony. This multivariate statistical technique is also able to assess the importance of each grammatical factor in the final model in relation to the notion of gradience. By making precise predictive statements about a non-discrete linguistic category, this investigation sheds light on the theory of linguistic performance rather than that of linguistic competence.
Metrology of 3D IC with X-ray Microscopy and nano-scale X-ray CT

Metrology of 3D integrated circuits (IC) have presented new challenges to existing metrology technologies, particularly in cases where the 3D structure of the sample must be measured non-destructively. X-ray microscopy, on the other hand, offers very deep penetration and better than 50 nm resolution, as well as ability to distinguish different elemental compositions. When combined with computed tomography (CT) technology, the full 3D structure of an IC an be obtained non-destructively at tens of nanometer accuracy, thus making x-ray nano-CT well suited for both metrology and failure analysis (FA) applications with 3D IC.
Multi-patch discontinuous Galerkin spline finite element methods for time-domain wave propagation

We present a class of spline finite element methods for time-domain wave propagation which are particularly amenable to explicit time-stepping. The proposed methods utilize a discontinuous Galerkin discretization to enforce continuity of the solution field across geometric patches in a multi-patch setting, which yields a mass matrix with convenient block diagonal structure. Over each patch, we show how to accurately and efficiently invert mass matrices in the presence of curved geometries by using a weight-adjusted approximation of the mass matrix inverse. This approximation restores a tensor product structure while retaining provable high order accuracy and semi-discrete energy stability. We also estimate the maximum stable timestep for spline-based finite elements and show that the use of spline spaces result in less stringent CFL restrictions than equivalent piecewise continuous or discontinuous finite element spaces. Finally, we explore the use of optimal knot vectors based on L2 n-widths. We show how the use of optimal knot vectors can improve both approximation properties and the maximum stable timestep, and present a simple heuristic method for approximating optimal knot positions. Numerical experiments confirm the accuracy and stability of the proposed methods.
The Doctor on the Patient's Turf: Assessing Patient Satisfaction with Physician Home Visit Programs

ABSTRACT We evaluated a physician home visit program (n = 23 patients) focusing on program implementation and quality. Quality was measured by evaluating patient satisfaction with services using a patient satisfaction scale and interviews with patients, caregivers, and providers. Scale results showed patients expressed the highest satisfaction with access to routine care and physician consideration. Patients expressed less satisfaction with access to emergency care and continuity of care. Physician communication and integration with home- and community-based service providers were other areas of concern. Recommendations include enhancing physician communication skills in the home, providing care for urgent medical conditions, improving chart documentation, and incorporating community-based chronic care experts into the program.
Early neonatal mortality: an analysis of multiple causes of death by the Grade of Membership method

Estudo de base populacional para determinar perfis de obitos neonatais precoces ocorridos em Belo Horizonte, Minas Gerais, Brasil, de 2000 a 2003. A definicao dos perfis de causas amplia possibilidade de analise sob enfoque de evitabilidade, justificada pela persistencia de altas taxas de mortalidade neonatal precoce. Tres perfis foram gerados, a partir do enfoque de causas multiplas, sob a perspectiva dos conjuntos nebulosos ("fuzzy sets"), utilizando-se tecnica Grade of Membership. Relacionaram-se esses perfis ao peso de nascimento e a natureza juridica do hospital de ocorrencia do obito. Nos hospitais da rede privada ocorreram "obitos dificilmente preveniveis, com mencao de malformacao congenita" (perfil 2). Aos hospitais do Sistema Unico de Saude (SUS) associaram-se dois perfis distintos. Nos hospitais contratados/conveniados ocorreram os "obitos passiveis de prevencao" (perfil 1) e na rede propria os "obitos de prematuros" (perfil 3). A tipologia observada aponta para necessidade de adocao de politicas diferenciadas na rede SUS: prioritariamente, na rede contratada/conveniada, acoes voltadas para credenciamento e avaliacao da qualidade da assistencia; e, em toda rede, adocao rotineira de protocolos assistenciais e medidas profilaticas, redutores da morbimortalidade neonatal.
