Study of Google Popularity Times Series for Commercial Establishments of Curitiba and Chicago

Urban computing is a recent area of study that helps us to understand the nature of urban phenomena. In this sense, an important aspect to study is the dynamics of commercial establishments popularity in the city. Recently, Google launched a new service that provides popularity time series of some commercial establishments in several cities. This is a valuable source of data that allow us to better understand the dynamics of establishments popularity, helping to change our perceived physical limits about the city, which can enable the development of new applications and urban services. The results of this study are: (1) characterization of Google popularity time series for bars and restaurants in the cities of Curitiba/Brazil and Chicago/USA. Among the results, we find cultural characteristics of these cities, as well as a favorable clustering of similar venues based on the temporal pattern of popularity; (2) evaluation of reproduction of Google popularity time series using Foursquare data. In this evaluation, we found evidence that Foursquare data might be used for this purpose. This means that for places where Google does not offer this service data from Foursquare, or other source, could be used. This enables the exploration of a greater number of establishments in, for example, a new venue recommendation engine.
Immunoglobulin composition of human antibodies to type 12 streptococcal M protein.

bodies in human serum. Excess antigen was added to specimens of serum, and specific rabbit antiserum for human IgG, IgA, or IgM was then used to coprecipitate the radioactive antigen bound to antibody in each immunoglobulin class (radioimmunoprecipitation). The results indicated acceptable specificity, since the antigen was bound specifically only by sera that contained type 12specific antibodies. Specimens of human serum contained antibodies in the IgG and IgA classes, but no sera had detectable IgM-antibody. Levels of IgG antibodies were always higher than those of IgA-antibodies, but IgA values were more
A minimal intervention to promote smoke-free homes among 2-1-1 callers: a randomized controlled trial.

OBJECTIVES We tested the efficacy of a minimal intervention to create smoke-free homes in low-income households recruited through the United Way of Greater Atlanta 2-1-1, an information and referral system that connects callers to local social services. METHODS We conducted a randomized controlled trial (n=498) from June 2012 through June 2013, with follow-up at 3 and 6 months. The intervention consisted of 3 mailings and 1 coaching call. RESULTS Participants were mostly smokers (79.7%), women (82.7%), African American (83.3%), and not employed (76.5%), with an annual household income of $10,000 or less (55.6%). At 6-months postbaseline, significantly more intervention participants reported a full ban on smoking in the home than did control participants (40.0% vs 25.4%; P=.002). The intervention worked for smokers and nonsmokers, as well as those with or without children. CONCLUSIONS Minimal intervention was effective in promoting smoke-free homes in low income households and offers a potentially scalable model for protecting children and adult nonsmokers from secondhand smoke exposure in their homes.
The Role of Human Immunodeficiency Virus Type 1 Envelope Glycoproteins in Virus Infection (*)

Enveloped viruses enter cells by a two-step process. The first step involves the binding of a viral surface protein to receptors on the plasma membrane of the host cell. After receptor binding, a membrane fusion reaction takes place between the lipid bilayer of the viral envelope and host cell membranes. This fusion reaction can occur either at the plasma membrane or in acidic endosomes following receptor-mediated endocytosis. In either case, the membrane fusion reaction delivers the viral nucleocapsid into the host cytoplasm, allowing the infection to proceed. Viral proteins embedded in the lipid bilayer of the viral envelope (known variously as surface, spike, or envelope proteins) catalyze receptor binding and membrane fusion reactions. The critical involvement of these viral proteins in receptor binding and membrane fusion has stimulated intensive investigation aimed at understanding the mechanisms by which these proteins function. In this article, we provide a brief overview of the roles envelope (Env) glycoproteins play in the human immunodeficiency virus type 1 (HIV-1) life cycle.
Implementation of laboratory order data in BioSense Early Event Detection and Situation Awareness System.

INTRODUCTION Laboratory test orders constitute an early outbreak data source. CDC receives laboratory order data in HL7 format from the Laboratory Corporation of America (LabCorp) and plans to use the data in the BioSense Early Event Detection and Situation Awareness System. METHODS These LabCorp data contain information on tests ordered and include the type of test ordered and the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM)-coded reasons for the order. A consensus panel was formed to group test orders on the basis of expert opinion into eight standard syndrome categories to provide an additional data source for early outbreak detection. A laboratory order taxonomy was developed and used in the mapping consolidation phase. The five main classes of this taxonomy are miscellaneous functional tests, fluid screening tests, system-specific tests, tests for specific infections (by primary manifestation), and tests for specific noninfectious diseases. RESULTS Summary of numbers of laboratory order codes in each syndrome category are fever (53), respiratory (53), gastrointestinal (27), neurological (35), rash (37), lymphadenitis (20), localized cutaneous lesion (11), and specific infection (63). CONCLUSION With the daily use of laboratory order data in BioSense, the actual distribution of laboratory order codes in syndrome groups can be evaluated, allowing modification of the mapping.
L'estime de soi chez l'enfant déficient intellectuel.

Cette recherche etudie les aspects psychologiques de representations de soi chez l'enfant deficient intellectuel a travers une Echelle d'estime de soi (Etes). Nous l'avons soumise a deux groupes d'enfants âges de dix ans, l'un compose de trente eleves de CM2, l'autre de trente enfants de Classes d'integration scolaire (Clis). Les resultats montrent que les enfants deficients intellectuels legers ont un indice global de l'estime de soi comparable a celui des enfants tout-venant. Mais leur profil indique qu'il existe une difference de structure dans la mesure ou les scores concernant le Soi futur sont nettement inferieurs alors que le Soi scolaire est egal a celui des enfants tout-venant. Les questions relatives aux differentes formes de reussite sont discutees, notamment de la reussite motivationnelle, en vue d'aider ces enfants a se projeter dans le futur.
Pain services and prescription of opioid drugs in Ghana.

Pain is probably the commonest symptom that sends patients to seek medical attention. Many people in Ghana accept pain as part of their normal lives when it is mild or moderate in severity. For treatment, they go to community pharmacies or chemical shops to purchase pain relievers. Some individuals will procure substances or medications from friends and relatives for the relief of their pain.
Automatically Activated Attitudes as Mechanisms for Message Effects: The Case of Alcohol Advertisements

Alcohol advertisements may influence impulsive, risky behaviors indirectly, via automatically activated attitudes toward alcohol. Results from an experiment in which participants were exposed to either four alcohol advertisements, four control advertisements, or four drunk driving public service advertisements (PSAs) suggested that alcohol advertisements had more measurable effects on implicit than on explicit attitude measures. Moreover, there were significant indirect paths from alcohol advertisement exposure through automatically activated alcohol attitudes on willingness to engage in risky alcohol-related behaviors, notably drinking and driving. A mechanism that may explain how these advertisements activate automatic, nondeliberative alcohol attitudes was investigated. Associative evidence was found supportive of an evaluative conditioning mechanism, in which positive responses to an alcohol advertisement may lead to more positive automatically activated attitudes toward alcohol.
A hybrid ergodic-splitting method for pseudo-monotone equilibrium problems

In this paper, we consider the equilibrium problem for a pseudo-monotone function. For solving this problem, a hybrid ergodic-splitting method is proposed. We decompose the equilibrium function into two functions and then solve auxiliary problems for each decomposition function separately. Under pseudo-monotonicity of the equilibrium function and some additional assumptions, we prove that the sequence generated by algorithm converges to a solution of the problem.
Association Between Gadolinium Contrast Exposure and the Risk of Parkinsonism.

initial MRI was of the brain or spinal cord and those with prior parkinsonism or neurosurgery were excluded. Patients who were exposed to gadolinium-enhanced MRIs (modeled as a time-varying, cumulative count variable) were compared with patients who received non–gadolinium-enhanced MRIs. The primary outcome, assessed from the initial MRI until death, emigration, or March 2015, was a new diagnosis of parkinsonism based on a validated definition (sensitivity, 81.7%; specificity, 99.7%; positive predictive value, 78.0%; negative predictive value, 99.8%; accuracy, 99.5%; and disease prevalence, 1.4%) using diagnosis codes from hospital admissions and physician visits or a dispensed Parkinson disease–specific medication. 4 We measured 105 covariates 5 and evaluated significant inequalities between patients who underwent only non–gadolinium-enhanced MRIs and those who underwent 1 or more gadolinium-enhanced MRI. A subset of 38 covariates particularly rel-evant to parkinsonism (based on potential associations from the literature) or significantly different at baseline (standard-ized difference >10%) were included in a multivariable time-dependent extended Cox regression model using SAS (SAS Institute), version 9.4; the hazard ratio (HR) is interpreted as the hazard of parkinsonism per additional gadolinium exposure. 6 Sensitivity analyses adjusting for covariates with standardized differences of 9% or 10% and defining parkinsonism without medications 4 were performed. A 2-sided P value less than . 05 was considered significant. to temporal in the type of
Gibbs-Sampling-Based CRE Bias Optimization Algorithm for Ultradense Networks

Cell range expansion (CRE) is an effective technique in the ultradense network (UDN) to enlarge small cells' ranges and promote network utility such as system throughput, number of users lower than a rate threshold, and proportional fairness. Due to the coupled relationship of user association and scheduling in rate-related utility optimization, optimal cell-specific CRE bias is difficult to achieve. This paper first proposes a centralized CRE bias adjusting algorithm based on Gibbs sampling to achieve the optimal solution of cell-specific CRE bias based on global information. After that, a decentralized Gibbs-sampling-based CRE bias adjusting algorithm without the need for the entire knowledge of global channel gains is designed to deal with the computational complexity and message exchange overhead problem caused by scale expansion of UDN. Finally, to further reduce the increasing computational complexity, message exchange overhead, and time complexity caused by scale expansion of UDN, this paper constructs a neighbor graph based on the mutual bias influence among cells, develops a graph-coloring-based clustering algorithm to classify cells into groups, and proposes a central-aided distributed CRE bias adjusting algorithm to obtain the optimal solution to the rate-related utility optimization problem based on local information. In the central-aided distributed CRE bias adjusting algorithm, a central macrocell is used to collect the information from the small cells, and the small cells distributively determine their CRE bias based on shared central information. The optimality and complexity of the proposed algorithms are proven and analyzed. Numerical results show that, compared with existing schemes, the proposed Gibbs-sampling-based algorithms can achieve a larger utility function with less iteration time.
Fuzzy Logic Based Quality of Service Models Extended

The continuous monitoring of information systems’ quality of service increases importance as business becomes more and more dependent of those systems. In order to evaluate the quality of service of systems, models need to be defined, so the definition of quality is documented and shared by all relevant stakeholders. Because of their complexity and today modelling frameworks, quality of service models tend to result in a poor representation of reality, mainly because of their lack of ability to represent imprecision. Since the ability to represent reality is a fundamental property of models, only when a solution is found to this problem, better models will appear. In this work, we investigate the creation of quality of service models, for information systems, using as motivation the general structure of a fuzzy logic controller, the most successful application of fuzzy logic. The objective is to obtain models that are a better representation of reality, and by consequence easier to create and understand. This thesis also presents the investigation on related topics to support the identified problem and motivations, followed by the solution details proposal. Finally, the solution is applied in real world systems, from the collaboration with PT-Comunicações, to validate the given hypothesis.
Modulation of the Degree and Pattern of Methyl-esterification of Pectic Homogalacturonan in Plant Cell Walls

Homogalacturonan (HG) is a multifunctional pectic polysaccharide of the primary cell wall matrix of all land plants. HG is thought to be deposited in cell walls in a highly methyl-esterified form but can be subsequently de-esterified by wall-based pectin methyl esterases (PMEs) that have the capacity to remove methyl ester groups from HG. Plant PMEs typically occur in multigene families/isoforms, but the precise details of the functions of PMEs are far from clear. Most are thought to act in a processive or blockwise fashion resulting in domains of contiguous de-esterified galacturonic acid residues. Such de-esterified blocks of HG can be cross-linked by calcium resulting in gel formation and can contribute to intercellular adhesion. We demonstrate that, in addition to blockwise de-esterification, HG with a non-blockwise distribution of methyl esters is also an abundant feature of HG in primary plant cell walls. A partially methyl-esterified epitope of HG that is generated in greatest abundance by non-blockwise de-esterification is spatially regulated within the cell wall matrix and occurs at points of cell separation at intercellular spaces in parenchymatous tissues of pea and other angiosperms. Analysis of the properties of calcium-mediated gels formed from pectins containing HG domains with differing degrees and patterns of methyl-esterification indicated that HG with a non-blockwise pattern of methyl ester group distribution is likely to contribute distinct mechanical and porosity properties to the cell wall matrix. These findings have important implications for our understanding of both the action of pectin methyl esterases on matrix properties and mechanisms of intercellular adhesion and its loss in plants.
Exenatide and rare adverse events.

n engl j med 358;18 www.nejm. org may 1, 2008 1969 Editor’s note: We received 1610 responses, from 85 countries, for this medical mystery. Sixty-two percent of respondents were physicians in practice, 21% were physicians in training, and 12% were medical students. Of the respondents, 65% identified some type of diaphragmatic hernia on the radiograph, which revealed a retrocardiac gastric shadow (Panel A). Specifically, 46% suggested a hiatal hernia, and 13% proposed another type of diaphragmatic defect such as Bochdalek’s or Morgagni’s hernia; 6% correctly identified gastric volvulus. The remaining 35% of respondents suggested a variety of diagnoses, including aortic aneurysm, Boerhaave’s syndrome, Zenker’s diverticulum, thymoma, pulmonary abscess, and achalasia.
Output-feedback stabilization of discrete-time switched systems

This paper considers the closed-loop stabilization problem for discrete-time linear switched system. The state variables are assumed to be not accessible so that the feedback strategy hinges on given output variables. The solution of this problem is based on the solution of suitable matrix inequalities for the construction of a full order switched filter and the derivation of the stabilization rule. The main theoretical basis is constituted by the so-called Lyapunov-Metzler inequalities which play a prominent role in the state-feedback stabilization of linear switched systems. The theoretical results are illustrated by means of an academic example.
Impact Sourcing: Employing Prison Inmates to Perform Digitally-enabled Business Services

This chapter explores the practice of employing prisoners to perform business services for the public and private sectors. The International Centre for Prison Studies reports that there are 6,291,179 prisoners worldwide. The United States (US) has the greatest number of inmates with 2,193,789 prisoners and the highest incarceration rate at 737 inmates per 100,000 people compared to all other countries. Given that 95% of US inmates will one day be released and given that 70% of released inmates become repeat offenders (FPI 2012), any intervention that can help released inmates re-enter society successfully must have positive impacts on the individuals, their families and communities. Prison employment programs have been one such intervention method. In this chapter, we aim to study a special type of prison employment program: the hiring and training of prisoners to perform business services using a computer, otherwise known as “digitally enabled” business services (Carmel et al. 2013).
Dispersal: Risk Spreading versus Local Adaptation

I investigate how risk spreading in stochastic environments and adaptation to permanent properties of local habitats interplay in the simultaneous evolution of dispersal and habitat specialization. In a simple two‐patch model, I find many types of locally evolutionarily stable attractors of dispersal and of a trait involved in habitat specialization, including a single habitat specialist and a coalition of two specialists with low dispersal, a generalist with high dispersal, and several types of dispersal polymorphisms. In general, only one attractor is a global evolutionarily stable strategy (ESS). In addition to the ESS analysis, I also present some examples of the dynamics of evolution that exhibit adaptive diversification by evolutionary branching.
CTA in patients with acute subarachnoid haemorrhage: A comparative study with selective, digital angiography and blinded, independent review

Purpose: Minimal- or non-invasive methods replacing intra-arterial digital subtraction angiography (IA-DSA) would be of great importance in patients suffering from acute subarachnoid haemorrhage (SAH). The aims of this study were to compare CTA with IA-DSA in patients with acute SAH, to compare CTA interpretations with those of blinded, independent reviewers and to evaluate improvement in CTA diagnostics after 1 year of experience with CTA. Material and Method: During 2 years 162 patients with SAH underwent CTA as well as IA-DSA. Independent blinded review of 77 patients was performed for 1 year. Results: Totally 144 aneurysms were demonstrated in 119 patients at IA-DSA, while 43 patients had normal intracranial arteries. Initially 131 aneurysms were detected at CTA while 2 normal, tortuous arteries were misinterpreted as aneurysms, giving a sensitivity of 91% and a specificity of 95%. At independent blinded review the observer agreement was 87% and the kappa value 0.68. Conclusion: CTA in SAH is of great value in demonstrating vascular anatomy and the exact size of an aneurysm. However, IA-DSA is still needed for diagnostic evaluation in aneurysms smaller than 5 mm in diameter, especially in those located near bony structures.
Automated locomotion parameter tuning for an Anguilliform-inspired robot

Effectiveness of the locomotion of an Anguilliform-inspired robot depends upon the selection of various controller parameters such as amplitude, frequency, offset and low level controller gains. Manual tuning of the aforementioned parameters can be cumbersome. Automated controller parameter tuning requires repetitive experimental tests with non-optimal parameters leading to a rapid wear and tear of the robot. Use of dynamics simulator instead of a robot may alleviate this issue to some extent. However, reality gap may exist between a physical system and corresponding simulator. This paper reports an optimization based approach for determining environment parameters (added mass, added inertia and drag) from physical experiments followed by an optimization based automated parameter tuning utilizing the determined environment parameters via developed dynamics simulator. We report numerical simulations of waypoint following on different test paths using the identified environment parameters and optimized controller parameters determined using the developed approach. We found a reduction of up to 36% in travel time in our experiments. The developed approach can lead to a match between dynamics simulation and physical experiments and thereby can help in automated parameter tuning. In future, we would like to improve the performance of the optimization and to incorporate the sensing noise and environmental disturbance like current into the dynamics simulator.
