iKnow Where You Are

“Smart” phones, such as G1 and iPhone, have made their way into people’s lives with more intelligence owing to the continually decreasing cost and increasing access to memory capability, processing power and network bandwidth. This work attempts to detect presence in different environments like office, conference, meeting and traveling outdoors, using audio sensors on the G1 phone. Specifically, a two step process involving classifying the background first and then detecting the number of people in an environment is followed. Using the Vector Quantization method, audio is classified into five predefined classes. A recognition rate ranging from 86% to 100%for individual classes and 91%overall recognition accuracy was obtained. For speaker change detection via Bayesian Information Criterion, about 79.4% of all 350 test audio clips was correctly categorized.
Intraprocedural Stent Thrombosis During Implantation of Sirolimus-Eluting Stents

Background—Intraprocedural stent thrombosis (IPST) is a rare event (<0.01% in our experience with bare metal stents), with the exception of specific settings such as acute myocardial infarction, thrombus-containing lesions, and dissections. We report the occurrence of this event during elective implantation of sirolimus-eluting stents. Methods and Results—Between April 2002 and August 2003, 670 patients with 1362 lesions were treated with Cypher (Cordis, Johnson and Johnson Co) sirolimus-eluting stent implantation in San Raffaele Hospital and EMO Centro Cuore Columbus. Diabetes mellitus was present in 142 patients (21%), and 164 (24.5%) had unstable angina. Pretreatment with glycoprotein IIb/IIIa (GP IIb/IIIa) inhibitors was carried out in 235 patients (35%). Total stent length per vessel was 42.9±28.3 mm. IPST occurred in 5 patients (0.7%). None of the patients with IPST were pretreated with GP IIb/IIIa inhibitors. Using univariate exact logistic regression, only total stent length per vessel, in millimeters (exact OR, 1.03; 95% CI, 1.011 to 1.046; P = 0.0028), was associated with the occurrence of IPST. Conclusions—Stent length was associated with the occurrence of IPST. Particular attention will need to be directed to this potential complication when long sirolimus-eluting stents are being used.
LOCALIZATION OF V-CATEGORIES

Let V be a symmetric monoidal closed category with a suitably compatible simplicial model category structure. We show how to extend Dwyer and Kan's notion of simplicial localization to V -categories. This may for instance be applied to the case where our categories are enriched in suitable models for spectra.
The effects of three kinds of perceptual‐social stimulation on the development of institutionalized infants

In a traditional Institution, 48 infants, of both sexes, whose chronological age ranged from 2 to 3 months, were equally divided into four groups (3 experimental and 1 control group) and for a period of two months were submitted, daily, to three main types of stimulation: (1) perceptual, (2) social, and (3) perceptual ‐‐ social. A thought provoking conclusion emerges from the preliminary results: 2‐3‐months‐old institutionalized infants, who receive varied perceptual stimulation during a 10‐week period, present a developmental profile almost identical to the developmental profile of infants of the same age. I.Q. s and environment, who received, during the same length of time, a social stimulation through the agency of one person.
Resurrection of "Second Order" Models of Traffic Flow

We introduce a new "second order" model of traffic flow. As noted in [C. Daganzo, Requiem for second-order fluid with approximation to traffic flow, Transportation Res. Part B, 29 (1995), pp. 277--286], the previous "second order" models, i.e., models with two equations (mass and "momentum"), lead to nonphysical effects, probably because they try to mimic the gas dynamics equations, with an unrealistic dependence on the acceleration with respect to the space derivative of the "pressure. " We simply replace this space derivative with a convective derivative, and we show that this very simple repair completely resolves the inconsistencies of these models. Moreover, our model nicely predicts instabilities near the vacuum, i.e., for very light traffic.
Oral splint for temporomandibular joint disorders with revolutionary fluid system

Temporomandibular joint (TMJ) diseases and disorders refer to a complex and poorly understood set of conditions, manifested by pain in the area of the jaw and associated muscles and limitations in the ability to make the normal movements of speech, facial expression, eating, chewing, and swallowing. The conventional soft occlusal splint therapy is a much safer and effective mode of a conservative line of therapy in comparison to the surgical therapy for temporomandibular joint disorders (TMD). The purpose of this article is to review the Aqualizer™, an hydrostatic oral splint, as accurate, effective treatment and differential diagnostic tool in TMD that allow treating the patient's pain quickly and accurately saving valuable treatment time. The review article has been prepared doing a literature review from the world-wide web and pubmed/medline.
How do consumers search for and appraise health information on the world wide web? Qualitative study using focus groups, usability tests, and in-depth interviews

Abstract Objectives: To describe techniques for retrieval and appraisal used by consumers when they search for health information on the internet. Design: Qualitative study using focus groups, naturalistic observation of consumers searching the world wide web in a usability laboratory, and in-depth interviews. Participants: A total of 21 users of the internet participated in three focus group sessions. 17 participants were given a series of health questions and observed in a usability laboratory setting while retrieving health information from the web; this was followed by in-depth interviews. Setting: Heidelberg, Germany. Results: Although their search technique was often suboptimal, internet users successfully found health information to answer questions in an average of 5 minutes 42 seconds (median 4 minutes 18 seconds) per question. Participants in focus groups said that when assessing the credibility of a website they primarily looked for the source, a professional design, a scientific or official touch, language, and ease of use. However, in the observational study, no participants checked any “about us” sections of websites, disclaimers, or disclosure statements. In the post-search interviews, it emerged that very few participants had noticed and remembered which websites they had retrieved information from. Conclusions: Further observational studies are needed to design and evaluate educational and technological innovations for guiding consumers to high quality health information on the web. What is already known on this topic Little is known about how consumers retrieve and assess the quality of health information on the internet Qualitative data are needed to design educational and technological innovations to guide consumers to high quality health information What this study adds Users of the internet explore only the first few links on general search engines when seeking health information Consumers say that when assessing the credibility of a site they primarily look for the source, a professional design, and a variety of other criteria In practice, internet users do not check the “about us” sections of websites, try to find out who authors or owners of the site are, or read disclaimers or disclosure statements Very few internet users later remember from which websites they retrieved information or who stood behind the sites
Bortezomib and Arsenic Trioxide Activity on a Myelodysplastic Cell Line (P39): A Gene Expression Study

Objective: We aimed to understand the molecular pathways affected by bortezomib and arsenic trioxide treatment on myelomonocytoid cell line P39. Materials and Methods: Oligonucleotide microarray platforms were used for gene expression and pathway analysis. Confirmation studies were performed using quantitative real time PCR. Results: Bortezomib treatment has shown upregulated DIABLO and NF-κBIB (a NF-κB inhibitor) and downregulated NF-κB1, NF-κB2, and BIRC1 gene expressions. Combination treatment of the two compounds showed gene expression deregulations in concordance by the results of single bortezomib treatment. Especially, P53 was a pathway more significantly modified and a gene network centralized around the beta estradiol gene. Beta estradiol, BRCA2, and FOXA1 genes were remarkable deregulations in our findings. Conclusion: Results support the suggestions about possible use of proteasome inhibitors in the treatment of high-risk myelodysplastic syndrome (MDS). NF-κB was observed as an important modulator in leukemic transformation of MDS.
Micro‐Computed Tomography for Visualizing Limb Skeletal Regeneration in Young Xenopus Frogs

For studies of vertebrate limb regeneration it is often desirable to visualize the regenerated skeleton, which is mostly cartilage, and also section the specimen for histological or immunohistochemical visualization of other tissues. However, the normal skeletal staining techniques are incompatible with immunohistochemistry. Here, we describe a contrast‐based micro‐computed tomography (microCT) method for direct and nondestructive observation of regenerated cartilage spikes in Xenopus frog limbs. In addition, we show that contrast based microCT imaging is compatible with immunohistochemistry protocols. This approach provides versatile and high contrast images of the cartilage allowing us to measure the regenerated skeletal structure in detail as well as carrying out the other types of analysis. It opens a wide range of potential microCT applications in research on vertebrate limb regeneration. Anat Rec, 2012. © 2012 Wiley Periodicals, Inc.
A multi-scale perspective of TRMM-LBA convection

This study presents an overview of Amazonian convection from the perspective of both ground and satellite instrumentation, with particular emphasis on radar observations of two MCSs (mesoscale convective systems) that occurred during the TRMM-LBA field campaign. The MCSs formed in different meteorological regimes, based on profiles of atmospheric wind and thermodynamic data. The radar analyses show that the MCSs were distinct in terms of kinematic and microphysical characteristics. These observations suggest that the easterly and westerly wind regimes in the southwest Amazon region produce convection with different vertical structure characteristics, similar to regimes elsewhere in the global tropics (e.g., maritime continent).
Link Prediction in Networks with Nodes Attributes by Similarity Propagation

The problem of link prediction has attracted considerable recent attention from various domains such as sociology, anthropology, information science, and computer sciences. A link prediction algorithm is proposed based on link similarity score propagation by a random walk in networks with nodes attributes. In the algorithm, each link in the network is assigned a transmission probability according to the similarity of the attributes on the nodes connected by the link. The link similarity score between the nodes are then propagated via the links according to their transmission probability. Our experimental results show that it can obtain higher quality results on the networks with node attributes than other algorithms.
Social Anxiety Disorder and Alcohol Use

Social anxiety disorder—an excessive fear of social situations, such as eating or speaking in public—affects 2 to 13 percent of the U.S. population. About one-fifth of patients with social anxiety disorder also suffer from an alcohol use disorder (AUD) (i.e., alcohol abuse or dependence). One theory to explain the comorbidity between social anxiety disorder and AUDs is the tension reduction theory, which posits that people with social anxiety use alcohol to alleviate their fears. This expectation that alcohol reduces anxiety may motivate alcohol consumption even if pharmacological studies do not support that assumption. Social anxiety disorder is treatable with both pharmacotherapy and psychotherapy, and some of those treatments also would be expected to be effective for patients with comorbid AUDs. Evaluation of patients seeking alcoholism treatment for coexisting social anxiety disorder is important for improving treatment outcome.
A cell surface display system using novel GPI‐anchored proteins in Hansenula polymorpha

A cell surface display system was developed in yeast Hansenula polymorpha.The four genes HpSED1, HpGAS1, HpTIP1and HpCWP1, encoding glycosylphosphatidyl‐inositol (GPI)‐anchored cell surface proteins from H. polymorpha, were cloned, characterized and evaluated for their efficacies as cell surface display motifs of reporter proteins. Sequence analysis of these genes revealed that each encodes a typical GPI‐anchored protein that is structurally similar to a counterpart gene in S. cerevisiae. The genes showed a high content of serine‐threonine (alanine) and harboured a putative secretion signal in the N‐terminus and the GPI‐attachment signal in the C‐terminus. The surface anchoring efficiency of these putative cell surface proteins was tested by fusion to the C‐terminal of carboxymethylcellulase (CMCase) from Bacillus subtilis. In all cases, high CMCase activities were detected in intact cell fraction, indicating anchoring of CMCase to the cell surface. HpCwp1p, HpGas1p and the 40 C‐terminal amino acids of HpTip1p from H. polymorphaexhibited a comparatively high CMCase surface anchoring efficiency. When these proteins were used as anchoring motifs for surface display of the glucose oxidase (GOD) from Aspergillus niger, most enzyme activity was detected at the cell surface. Fluorescence activated cell sorter (FACS) analysis of cells displaying GOD on the cell surface demonstrated that GOD was well exposed on the cell surface. HpCwp1p showed the highest anchoring efficiency among others. Copyright © 2002 John Wiley & Sons, Ltd.
Tight bounds for 2-dimensional indexing schemes

We study the trade-off between storage redundancy and access overhead for range queries, using the framework of [6]. We show that the Fibonacci workload of size n, which is the regular 2-dimensional grid rotated by the golden ratio, does not admit an indexing scheme with access overhead less than the block size B (the worst possible access overhead), even for storage redundancy as high as clogn, for some constant c. We also show that this bound is tight (up to a constant factor) by providing an indexing scheme with storage redundancy O(logn) and constant access overhead, for any 2-dimensional workload. We extend the lower bound to random point sets and show that if the maximum storage redundancy is less than cloglogn, the access overhead is 13, Finally, we explore the relation between indexability and fractal (Hausdorff) dimension of point sets.
Systolic Peak Detection in Acceleration Photoplethysmograms Measured from Emergency Responders in Tropical Conditions

Photoplethysmogram (PPG) monitoring is not only essential for critically ill patients in hospitals or at home, but also for those undergoing exercise testing. However, processing PPG signals measured after exercise is challenging, especially if the environment is hot and humid. In this paper, we propose a novel algorithm that can detect systolic peaks under challenging conditions, as in the case of emergency responders in tropical conditions. Accurate systolic-peak detection is an important first step for the analysis of heart rate variability. Algorithms based on local maxima-minima, first-derivative, and slope sum are evaluated, and a new algorithm is introduced to improve the detection rate. With 40 healthy subjects, the new algorithm demonstrates the highest overall detection accuracy (99.84% sensitivity, 99.89% positive predictivity). Existing algorithms, such as Billauer's, Li's and Zong's, have comparable although lower accuracy. However, the proposed algorithm presents an advantage for real-time applications by avoiding human intervention in threshold determination. For best performance, we show that a combination of two event-related moving averages with an offset threshold has an advantage in detecting systolic peaks, even in heat-stressed PPG signals.
Leading Organizational Learning Through Authentic Dialogue

This article explores how authentic leaders enable learning in organizations through the mechanism of dialogue. Using Crossan et al.'s multi-level framework, we examine how top managers who exhibit the authentic leadership capabilities of self-awareness, balanced processing, self-regulation and relational transparency can shape an organizational culture characterized by authentic dialogue. This culture then supports feed-forward and feedback learning across individual, group and organizational levels, promoting and reinforcing double-loop learning. We develop propositions that integrate the leadership and organizational learning literatures and offer suggestions for future research.
Computational Statistics and Data Analysis

Excess zeros and overdispersion are common phenomena that limit the use of traditional Poisson regression models for modeling count data. Both excess zeros and overdispersion caused by unobserved heterogeneity are accounted for by the proposed zero-inflated Poisson (ZIP) regression mixture model. To estimate the parameters of the model, an EM algorithm with an embedded iteratively reweighted least squares method is implemented. The parameter estimation performance of the proposed model is evaluated through simulation studies. The ZIP regression mixture model is applied to the DMFT index dataset, which contains excess zeros and overdispersion. Comparisons of several other models commonly used for such data with the ZIP regression mixture model show that, in general, the latter model fits the data well.
Changing Vocabularies of Taste, 1967‐92:

Summarizes the findings of a systematic comparison of articles about food and its preparation in popular British women′s magazines in 1967‐68 and 1991‐92. The texts were subjected to a rudimentary content analysis and have been interpreted in terms of a series of four antinomies which are used to recommend recipes to readers. Outlines some trends in discursive practices in the field of food. Analyses these in terms of rationalization, the routinization of the exotic, the ideology of personal choice and the institutionalization of anxiety.
Enhancing Interventions with Delinquent Youths

Abstract Although recent juvenile arrest trends are encouraging, a celebration of reduced juvenile delinquency is premature. Interventions with juvenile and adult offenders using structured behavioral and cognitive behavioral interventions show the strongest effects, but consistently modest effect sizes. There is increasing awareness of the comorbidity of juvenile delinquency and depression, which has a prevalence of between 14% and 23% in juvenile justice populations. Research evidence indicates that depressed youth who are aggressive differ from their non-de-pressed peers in their cognitive styles. Cognitive behavioral interventions are efficacious with depressed adolescents and should be more consistently applied and researched in juvenile justice settings.
Image-based global localization using VG-RAM Weightless Neural Networks

Mapping and localization are fundamental problems in autonomous robotics. Autonomous robots need to know where they are in their area of operation to navigate through it and to perform activities of interest. In this paper, we propose an Image-Based Global Localization (VibGL) system that uses Virtual Generalizing Random Access Memory Weightless Neural Networks (VG-RAM WNN). For mapping, we employ a VG-RAM WNN that learns the world positions associated with the images captured along a trajectory. During the localization, new images from the trajectory are presented to the VG-RAM WNN, which outputs their positions in the world. We performed experiments with our VibGL system applied to the problem of localizing an autonomous car. Our experimental results show that the system is able to learn large maps (several kilometers in length) of real world environments and perform global localization with median pose precision of about 3m. Considering a tolerance of 10m VibGL is able to localize the car 95% of the time.
Spatial Point Pattern Analysis of Neurons Using Ripley's K-Function in 3D

The aim of this paper is to apply a non-parametric statistical tool, Ripley's K-function, to analyze the 3-dimensional distribution of pyramidal neurons. Ripley's K-function is a widely used tool in spatial point pattern analysis. There are several approaches in 2D domains in which this function is executed and analyzed. Drawing consistent inferences on the underlying 3D point pattern distributions in various applications is of great importance as the acquisition of 3D biological data now poses lesser of a challenge due to technological progress. As of now, most of the applications of Ripley's K-function in 3D domains do not focus on the phenomenon of edge correction, which is discussed thoroughly in this paper. The main goal is to extend the theoretical and practical utilization of Ripley's K-function and corresponding tests based on bootstrap resampling from 2D to 3D domains.
The SRI/OGI 2006 spoken term detection system

This paper describes the system developed jointly at SRI and OGI for participation in the 2006 NIST Spoken Term Detection (STD) evaluation. We participated in the three genres of the English track: Broadcast News (BN), Conversational Telephone Speech (CTS), and Conference Meetings (MTG). The system consists of two phases. First, audio indexing, an offline phase, converts the input speech waveform into a searchable index. Second, term retrieval, possibly an online phase, returns a ranked list of occurrences for each search term. We used a word-based indexing approach, obtained with SRI’s large vocabulary Speech-to-Text (STT) system. Apart from describing the submitted system and its performance on the NIST evaluation metric, we study the tradeoffs between performance and system design. We examine performance versus indexing speed, effectiveness of different index ranking schemes on the NIST score, and the utility of approaches to deal with out-of-vocabulary (OOV) terms.
Assessment of privacy enhancing technologies for biometrics

Biometric privacy-enhancing technologies (PET) include two major groups: Biometric Encryption and Cancelable Biometrics. They enhance both privacy and security of a biometric system, thus embodying the Privacy by Design principles in a way that benefits the individual and minimizes the privacy risks. In this paper, the results of independent third-party evaluation of a commercial biometric PET product are presented. The GenKey “BioCryptic® ID Management System” is evaluated against a benchmark commercial product, Neurotechnology VeriFinger version 6.3. The database contained approximately 20,000 flat fingerprint images from 1,200 subjects. For a two-finger, two images per finger enrollment, the best results are: at FMR = 0.1%, FNMR = 1.54% for the PET System and FNMR = 1.74% for the benchmark system; at FMR = 0.01%, FNMR = 2.41% for the PET System and FNMR = 1.74% for the benchmark system. The results also suggest that specific subjects are substantially more likely than others to cause false matches. Security issues of the PET system are briefly discussed but no security evaluation is performed. The study demonstrates the viability of fingerprint-based PETs from a matching accuracy perspective.
