Propagating stress-pulses and wiggling transition revealed in string dynamics

Understanding string dynamics yields insights into the intricate dynamic behaviors of various filamentary thin structures in nature and industry covering multiple length scales. In this work, we investigate the planar dynamics of a flexible string where one end is free and the other end is subject to transverse and longitudinal motions. Under transverse harmonic motion, we reveal the propagating pulse structure in the stress profile over the string, and analyze its role in bringing the system into a chaotic state. For a string where one end is under longitudinal uniform acceleration, we identify the wiggling transition, derive the analytical wiggling solution from the string equations, and present the phase diagram.
eural correlates of metacognition : A critical perspective n current tasks

Humans have a remarkable ability to reflect upon their behavior and mental processes, a capacity known as metacognition. Recent neurophysiological experiments have attempted to elucidate the neural correlates of metacognition in other species. Despite this increased attention, there is still no operational definition of metacognition and the ability of behavioral tasks to reflect metacognition is the subject of debate. The most widely used task for studying metacognition in animals, the uncertain-option task, has been criticized because it can be solved by simple associative mechanisms. Here we propose a broad perspective that generalizes those critiques to another task, post-decision wagering. Moreover, we extend
Effects of Snow Boundary Generated Baroclinicity on Middle Latitude Disturbances

It is understood that snow cover has the potential to influence synoptic dynamics through latent heating and surface albedo effects. Gaining a deeper understanding of these interactions is important in order to predict how a changing climate will affect these feedback mechanisms. Previous work has shown that a temperature gradient can be set up across the snow pack boundary, generating baroclinicity, and influencing mid-latitude storm tracks. In this work, we will discuss if the previously found relationship has a storm size dependency such that enhanced baroclinicity generation only holds for small mid-latitude cyclones. This will be determined by statistical analysis of case studies and further investigation using the Weather Research and Forecasting Model (WRF). Preliminary outputs of the WRF simulations will be discussed along with the conclusions from the case study analyses.
Embedding Syntax and Semantics of Prepositions via Tensor Decomposition

Prepositions are among the most frequent words in English and play complex roles in the syntax and semantics of sentences. Not surprisingly, they pose well-known difficulties in automatic processing of sentences (prepositional attachment ambiguities and idiosyncratic uses in phrases). Existing methods on preposition representation treat prepositions no different from content words (e.g., word2vec and GloVe). In addition, recent studies aiming at solving prepositional attachment and preposition selection problems depend heavily on external linguistic resources and use dataset-specific word representations. In this paper we use word-triple counts (one of the triples being a preposition) to capture a preposition’s interaction with its attachment and complement. We then derive preposition embeddings via tensor decomposition on a large unlabeled corpus. We reveal a new geometry involving Hadamard products and empirically demonstrate its utility in paraphrasing phrasal verbs. Furthermore, our preposition embeddings are used as simple features in two challenging downstream tasks: preposition selection and prepositional attachment disambiguation. We achieve results comparable to or better than the state-of-the-art on multiple standardized datasets.
Translation shifts in multimodal text : a case of the Thai version of Cosmopolitan

The American lifestyle women’s magazine Cosmopolitan is currently available in different versions worldwide. The magazine’s focus on the female ‘liberated’ lifestyle, in which women’s intimate relationships are the central theme, however, does not always sit comfortably with culture in Eastern societies. Adaptation of Western narratives and illustrations is sometimes necessary. This leads to shifts in meaning in both verbal and visual semiotic resources in the translated text. Since the magazine is a multimodal text, analyzing both verbal and visual elements can potentially be more productive than examining either one of these two constituents in isolation. This study applies the systemic functional linguistic model of text and context relationships, supplemented with social semiotics’ ‘visual meanings. ’ An integrated tool of analysis is proposed as an appropriate instrument to examine and explain the overall translation shifts in the
Telemedicine SMS-Based ECG Monitoring System

In this contemporary world where technology is advancing rapidly, design and development of a continuous remote ECG Monitoring System will be of immense help to modern healthcare. Deploying telemedicine principles, the developed system suggests a practical and feasible solution for continuously monitoring the postoperative conditions of cardiac patients especially the old age. The mobile phone technology which has gained tremendous popularity when used as an interlink between the patient and the physician or the medical practitioner will be a familiar platform for both of them. Our system proposes the design of a real time, ECG monitoring system via a GSM platform which will include an alert system with a notification mechanism to alert the concern physician of the patient’s condition in case of any abnormalities.
Testimonial Psychotherapy in Immigrant Survivors of Intimate Partner Violence: A Case Series

Testimonial psychotherapy is a therapeutic ritual for facilitating the recovery of survivors of human rights violations that focuses on sharing the trauma narrative. Originally developed in Chile as a method for collecting evidence during legal proceedings, testimonial therapy has been widely applied transculturally as a unique treatment modality for populations that are not amenable to traditional Western psychotherapy. In this case report, we first review the literature on testimonial therapy to this date. We go on to describe how testimonial therapy has been specifically adapted to facilitate recovery for immigrant survivors of intimate partner violence (IPV). We present three Latin American women who underwent testimonial psychotherapy while receiving psychiatric treatment at a Northern Virginia community clinic affiliated with the George Washington University. The therapy consisted of guided trauma narrative sessions and a Latin- American Catholic inspired reverential ceremony in a Spanish-speaking women's domestic violence group. In this case series we provide excerpts from the women's testimony and feedback from physicians who observed the ceremony. We found that testimonial psychotherapy was accepted by our three IPV survivors and logistically feasible in a small community clinic. We conceptualize testimonial psychotherapy as a humanistic therapy that focuses on strengthening the person. Our case report suggests testimonial psychotherapy as a useful adjunct to formal psychotherapy for post-traumatic stress symptoms.
Virulence factors of the human opportunistic pathogen Serratia marcescens identified by in vivo screening

The human opportunistic pathogen Serratia marcescens is a bacterium with a broad host range, and represents a growing problem for public health. Serratia marcescens kills Caenorhabditis elegans after colonizing the nematode's intestine. We used C.elegans to screen a bank of transposon‐induced S.marcescens mutants and isolated 23 clones with an attenuated virulence. Nine of the selected bacterial clones also showed a reduced virulence in an insect model of infection. Of these, three exhibited a reduced cytotoxicity in vitro, and among them one was also markedly attenuated in its virulence in a murine lung infection model. For 21 of the 23 mutants, the transposon insertion site was identified. This revealed that among the genes necessary for full in vivo virulence are those that function in lipopolysaccharide (LPS) biosynthesis, iron uptake and hemolysin produc tion. Using this system we also identified novel conserved virulence factors required for Pseudomonas aeruginosa pathogenicity. This study extends the utility of C.elegans as an in vivo model for the study of bacterial virulence and advances the molecular understanding of S.marcescens pathogenicity.
Do foreign portfolio capital flows affect domestic investment? Evidence from Brazil

Although there are several direct and indirect theoretical channels through which foreign capital flows may affect domestic investment, empirical evidence remains inconclusive. In this paper, we employ a VARX framework to assess the impact of Equity Foreign Portfolio Investment (EFPI) on domestic investment growth, employing monthly series of capital flows and gross capital formation for the Brazilian economy. Our results suggest that EFPI played a non-negligible role in explaining aggregate investment fluctuations, but only before the 2008 global financial crisis. After the crisis, a period marked first by a shift in economic policy in 2008-09, with substantial increases in government intervention, followed by deterioration in the institutional outlook and political stability in 2014-15, mostly against the backdrop of the Petrobras corruption scandal, unexpected shocks to EFPI no longer led any real effects on investment growth. Whilst, in general, our results vouch for beneficial effects of equity capital flows on investment, this virtuous relationship is likely disturbed by interventionist policies and political unrest.
Prevention Of Black Hole Attacks In AODV-Based Manets Using Secure Route Discovery

Without an establishment of infrastructure or a central network authority Mobile Ad-hoc Networks (MANETs) allow communication of mobile with each other over a network. Due to this condition, the MANETs have dynamic topologies, this case is because the nodes can easily join or leave the network at any time. MANETs are vulnerable to various types of malicious attacks, for this situation a security design perspective is necessary. Ad-hoc Ondemand Distance Vector (AODV), which is one of the standard MANET protocols, can be attacked by malicious nodes. The one type of malicious attack is a black hole attack that can be easily employed against data routing in MANETs . In this case a black hole node replies to route requests rapidly from the shortest path and the highest destination sequence number. Without any active route and without any specified destination associated with it the black hole node drops all of the data packets that it receives. My mechanism that provides Secure Route Discovery for the AODV protocol in order to prevent black hole attacks. Security is a key feature in MANETs so by using cryptography technique for securing route discovery and data transmission.

Aura Mesh: Motion Retargeting to Preserve the Spatial Relationships between Skinned Characters

Applying motion‐capture data to multi‐person interaction between virtual characters is challenging because one needs to preserve the interaction semantics while also satisfying the general requirements of motion retargeting, such as preventing penetration and preserving naturalness. An efficient means of representing interaction semantics is by defining the spatial relationships between the body parts of characters. However, existing methods consider only the character skeleton and thus are not suitable for capturing skin‐level spatial relationships. This paper proposes a novel method for retargeting interaction motions with respect to character skins. Specifically, we introduce the aura mesh, which is a volumetric mesh that surrounds a character's skin. The spatial relationships between two characters are computed from the overlap of the skin mesh of one character and the aura mesh of the other, and then the interaction motion retargeting is achieved by preserving the spatial relationships as much as possible while satisfying other constraints. We show the effectiveness of our method through a number of experiments.

Association between Orofacial Pain and other Symptoms : a Population-based Study

Results: The current study showed an association between self-reported OFP and all the other symptoms measured. The strongest association was found for a high level of sleep disturbance (relative risk (RR) 3.7; 95% Confidence Interval (CI) 2.94. 9), tenderness of jaw muscles in the morning (RR 3.7; 95% CI 3.3-4.1), persons with frequent headaches (RR 3.1; 95% CI 2.7-3.5), and tiredness or stiffness of jaw muscles (RR 2.6; 95% CI 2.3-3.0). Having pain in the body other than the head was associated with a relative risk of OFP of 1.6 (95% CI 1.4-1.9), and increased risk persisted when individual body locations were considered (back, abdominal, forearm, shoulder and knee pain). Those who took medication for bowels had a higher risk of OFP (RR 1.4; 95% CI 1.1-1.8). Problems with micturition were associated with an elevated risk of 1.5 (95% CI 1.02.0). None of these results changed significantly after adjustment for age and gender.
- 1-Modeling Socio-Cultural Phenomena in Discourse

In this paper, we describe a novel approach to computational modeling and understanding of social and cultural phenomena in multi-party dialogues. We developed a two-tier approach in which we first detect and classify certain socio-linguistic behaviors (SLB), including topic control, disagreement, and involvement, that serve as first order models from which presence the higher level social roles, such as leadership, may be inferred.
A multi-agent based analytical approach for service restoration in distribution networks

With the advent of smart grids and the higher level of requirement for the quality of supply, restoration of distribution networks is a timely topic that deserves to be revisited. In this paper, the concept of multi-agent automation in smart grids is applied to build a self-healing framework to be used for the restoration service. The optimal restoration solution is found solving a global optimization problem in a distributed way. The restoration problem including power flow equations is modeled as a second order cone programming problem and carried out on a 70-bus distribution network. The model is implemented in Matlab/Yalmip toolbox and solved using Gurobi solver.
The Challenges of Knowledge Management Portals Application and Implementation: The Iranian Organizations Case Study

This article aims to review, identify and prioritize challenge factors of the implementation of knowledge management portals for Iranian organizations. The study determines several important weakness factors affecting the implications of the knowledge management such as the weakness in organizational strategy, information overcrowd, content management, portals project management, etc. The study also indicates that the factors have different priorities where managerial factors are in the highest priority and financial factors are in the lowest priority. We also perform factor analysis to summarize seventeen factors into six issues: Financial and information security, Technology and management, Senior management support and strategy, Acceptance, User's motivation and culture, Project management, Change management and training. Knowledge management portal is a brand new concept for Iranian organizations and it is hard to gather information from limited number of organizations or companies for applied knowledge management portals. The results of this study could be useful for knowledge management planners and managers in organizations and clear the prospects to deal with the challenges.
HST AND SPITZER OBSERVATIONS OF THE HD 207129 DEBRIS RING

A debris ring around the star HD 207129 (G0V; d = 16.0 pc) has been imaged in scattered visible light with the ACS coronagraph on the Hubble Space Telescope (HST) and in thermal emission using MIPS on the Spitzer Space Telescope at λ = 70 μm (resolved) and 160 μm (unresolved). Spitzer IRS (λ = 7–35 μm) and MIPS (λ = 55–90 μm) spectrographs measured disk emission at λ> 28 μm. In the HST image the disk appears as a ∼30 AU wide ring with a mean radius of ∼163 AU and is inclined by 60° from pole-on. At 70 μm, it appears partially resolved and is elongated in the same direction and with nearly the same size as seen with HST in scattered light. At 0.6 μm, the ring shows no significant brightness asymmetry, implying little or no forward scattering by its constituent dust. With a mean surface brightness of V = 23.7 mag arcsec−2, it is the faintest disk imaged to date in scattered light. We model the ring's infrared spectral energy distribution (SED) using a dust population fixed at the location where HST detects the scattered light. The observed SED is well fit by this model, with no requirement for additional unseen debris zones. The firm constraint on the dust radial distance breaks the usual grain size–distance degeneracy that exists in modeling of spatially unresolved disks, and allows us to infer a minimum grain size of ∼2.8 μm and a dust size distribution power-law spectral index of −3.9. An albedo of ∼5% is inferred from the integrated brightness of the ring in scattered light. The low-albedo and isotropic scattering properties are inconsistent with Mie theory for astronomical silicates with the inferred grain size and show the need for further modeling using more complex grain shapes or compositions. Brightness limits are also presented for six other main-sequence stars with strong Spitzer excess around which HST detects no circumstellar nebulosity (HD 10472, HD 21997, HD 38206, HD 82943, HD 113556, and HD 138965).
Spontaneous ion beam formation in the laboratory, space, and simulation

We present experimental evidence for the spontaneous formation of multiple double layers within a single divergent magnetic field structure. Downstream of the divergent magnetic field, multiple accelerated ion populations are observed. The similarity of the accelerated ion populations observed in these laboratory experiments to ion populations observed in the magnetosphere and in numerical simulations suggests that the observation of a complex ion velocity distribution alone is insufficient to distinguish between simple plasma expansion and magnetic reconnection. Further, the effective temperature of the aggregate ion population is significantly larger than the temperatures of the individual ion population components, suggesting that insufficiently resolved measurements could misidentify multiple beam creation as ion heating. Ions accelerated in randomly oriented electric fields that mimic heating would have an ion heating rate dependent on the ion charge and mass that is qualitatively consistent with recent experimental observations of ion heating during magnetic reconnection.

Experiments to Assess the Cost-Benefits of Test-Suite Reduction

Abstract Test-suite reduction techniques attempt to reduce the cost of saving and reusing test cases during software maintenance by eliminating redundant test cases from test suites. A potential drawback of these techniques is that in reducing a test suite they might reduce the ability of that test suite to reveal faults in the software. Previous studies suggested that test-suite reduction techniques can reduce test suite size without significantly reducing the fault-detection capabilities of test suites. To further investigate this issue we performed experiments in which we examined the costs and benefits of reducing test suites of various sizes for several programs and investigated factors that iduence those costs and benefits. In contrast to the previous studies, our results reveal that the fault-detection capabilities of test suites can be severely compromised by test-suite reduction.
Weak effects of habitat type on susceptibility to invasive freshwater species: an Italian case study.

Introduction of alien species is one of the major threats to aquatic biota and knowledge of the major correlates of their occurrence is pivotal in planning reliable conservation strategies. 2. To understand whether specific freshwater habitats are more likely to be invaded than others, a dataset on the occurrence of 1604 species in 54 taxonomic groups from 181 sites across the Italian peninsula was gathered. 3. TheEUNIShabitatclassificationwas used, selectingfor the study's seven habitat types at thesecondEUNIS level, including lentic (EUNIS C1; 64 sites), lotic (EUNIS C2; 99 sites) and highly artificial (EUNIS J5; 18 sites) habitats. 4. The aim of the study was to test whether the overall number of alien species and the proportion of alien species for each taxonomic group differed between habitat types and could be explained by environmental, human-mediated, or climatic factors. 5. Using generalized linear mixed effect models to account for potential confounding factors, only average air temperature of the site was a significant positive predictor of the occurrence of alien species, regardless of habitat type, species richness, and other climatic variables. 6. A direct effect of temperature could be excluded given the origin of alien species, mostly from colder areas than Italy. Thus, an indirect effect could be hypothesized at the Italian latitudes, with warmer areas potentially
