Real-time gait classification for persuasive smartphone apps: structuring the literature and pushing the limits

Persuasive technology is now mobile and context-aware. Intelligent analysis of accelerometer signals in smartphones and other specialized devices has recently been used to classify activity (e.g., distinguishing walking from cycling) to encourage physical activity, sustainable transport, and other social goals. Unfortunately, results vary drastically due to differences in methodology and problem domain. The present report begins by structuring a survey of current work within a new framework, which highlights comparable characteristics between studies; this provided a tool by which we and others can understand the current state-of-the art and guide research towards existing gaps. We then present a new user study, positioned in an identified gap, that pushes limits of current success with a challenging problem: the real-time classification of 15 similar and novel gaits suitable for several persuasive application areas, focused on the growing phenomenon of exercise games. We achieve a mean correct classification rate of 78.1% of all 15 gaits with a minimal amount of personalized training of the classifier for each participant when carried in any of 6 different carrying locations (not known a priori). When narrowed to a subset of four gaits and one location that is known, this improves to means of 92.2% with and 87.2% without personalization. Finally, we group our findings into design guidelines and quantify variation in accuracy when an algorithm is trained for a known location and participant.
Coronavirus-Specific CTL Epitopes Respiratory Syndrome-Associated Screening and Identification of Severe Acute

Severe acute respiratory syndrome (SARS) is a highly contagious and life-threatening disease that emerged in China in November 2002. A novel SARS-associated coronavirus was identiﬁed as its principal etiologic agent; however, the immunopathogenesis of SARS and the role of special CTLs in virus clearance are still largely uncharacterized. In this study, potential HLA-A*0201-restricted spike (S) and nucleocapsid protein-derived peptides were selected from an online database and screened for potential CTL epitopes by in vitro refolding and T2 cell-stabilization assays. The antigenicity of nine peptides which could refold with HLA-A*0201 molecules was assessed with an IFN- (cid:1) ELISPOT assay to determine the capacity to stimulate CTLs from PBMCs of HLA-A2 (cid:2) SARS-recovered donors. A novel HLA-A*0201-restricted decameric epitope P15 (S411–420, KLPDDFMGCV) derived from the S protein was identiﬁed and found to localize within the angiotensin-converting enzyme 2 receptor-binding region of the S1 domain. P15 could signiﬁcantly enhance the expression of HLA-A*0201 molecules on the T2 cell surface, stimulate IFN- (cid:1) -producing CTLs from the PBMCs of former SARS patients, and induce speciﬁc CTLs from P15-immunized HLA-A2.1 transgenic mice in vivo. Furthermore, signiﬁcant P15-speciﬁc CTLs were induced from HLA-A2.1-transgenic mice immunized by a DNA vaccine encoding the S protein;

A Novel WYSIWYG Approach for Generating Cross-Browser Web Data

Layout engine combines markup language (Html, etc) with formatting information (CSS, etc), and displays the combined contents on the screen. It is commonly used for many existing web development applications and web browsers. Especially, Web Development Applications use Layout Engine to confirm impact on the layout of web editing results to achieve What You See Is What You Get (WYSIWYG). At present, different layout engines are adopted by various web development applications and web browsers. As there is not a uniform algorithm adopted by layout engine, the results displayed by web development applications are not necessarily kept the same as displayed on the web browsers. In addition, the results displayed by web development applications are depended on layout engines. Hence it is difficult to edit the common web contents since it cannot objectively reflect the result on web browsers. In this paper, we proposes a novel WYSIWYG solution, by completely separating web layout design from web data editing to generate cross-browser web data. Our proposed approach does not use layout engine, and thus can avoid the disadvantages mentioned above.
Systemic Review and Meta-Analysis of the Clinical Efficacy and Adverse Effects of Zhengqing Fengtongning Combined with Methotrexate in Rheumatoid Arthritis

Chinese medicines are gaining wider acceptance. They have been used for treating rheumatoid arthritis (RA) for thousands of years, and the need to investigate the interaction between Chinese medicines and western medicines is widely recognized. In this study, a large number of RCTs and CCTs were analyzed to systematically assess the effects and adverse events of Zhengqing Fengtongning (ZQFTN) for RA. Eleven studies that contained 956 participants (508 in the treatment group; 448 in the control group) were included. The results showed that although ZQFTN combined with methotrexate MTX could not decrease the swollen joint count and tender joint count of RA patients better than MTX alone, the combination therapy might relieve the duration of morning stiffness (SMD: −16.06; 95% CI: −28.77 to −3.34), reduce laboratory indexes (RF: SMD: −10.84; 95% CI: −19.39 to −2.29; ESR: SMD: −7.26; 95% CI: −11.54 to −2.99; CRP: SMD: −3.66; 95% CI: −5.94 to −1.38), and improve the overall effect (RR: 1.08; CI: 1.01 to 1.16) better than monotherapy. The combination therapy was significantly better in controlling adverse drug reactions (RR: 0.60; 95% CI: 0.46 to 0.79). Through this systematic review, we found that ZQFTN combined with MTX for the treatment of RA might have better clinical efficacy than MTX only and might be superior in terms of controlling adverse drug reactions.
Adoption of object-oriented software metrics for ontology evaluation

Object-oriented software metrics are well established and widely acknowledged as a measure of software quality. The aim of our research is to analyze the potential use of some of these metrics for ontology evaluation. In this paper we present the conclusions of our feasibility study, in which we investigated and assessed the ability of software metrics to evaluate ontologies. Based on a review of existing literature, we chose a set of 18 object-oriented software metrics. These were categorized into four groups and analyzed according to their original definitions.
A novel edge based detection and PANDA framework approach for Indian license plate character recognition

Recognizing ASCII characters to reconstruct the license plate number remains a challenge particularly for Indian License Plates due to the heterogeneity of issues involved with Indian license plates. A character recognition algorithm is presented here based on combination of edge detection and PANDA framework; the edge based approach is used to find the shape of the each character in the license plate. The PANDA framework is a generic one used for the comparison of the two patterns. If the pattern is not exist in the data set it adds the pattern into the data set for future reference. By doing this, the recognition rate gets improved considerably. From the experimental results it is shown that the proposed method gives fairly acceptable level of accuracy for practical deployment of any Indian ALPR system.
Generation of α1,3-galactosyltransferase and cytidine monophospho-N-acetylneuraminic acid hydroxylase gene double-knockout pigs

Zinc-finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs) are new tools for producing gene knockout (KO) animals. The current study reports produced genetically modified pigs, in which two endogenous genes were knocked out. Porcine fibroblast cell lines were derived from homozygous α1,3-galactosyltransferase (GalT) KO pigs. These cells were subjected to an additional KO for the cytidine monophospho-N-acetylneuraminic acid hydroxylase (CMAH) gene. A pair of ZFN-encoding mRNAs targeting exon 8 of the CMAH gene was used to generate the heterozygous CMAH KO cells, from which cloned pigs were produced by somatic cell nuclear transfer (SCNT). One of the cloned pigs obtained was re-cloned after additional KO of the remaining CMAH allele using the same ZFN-encoding mRNAs to generate GalT/CMAH-double homozygous KO pigs. On the other hand, the use of TALEN-encoding mRNAs targeting exon 7 of the CMAH gene resulted in efficient generation of homozygous CMAH KO cells. These cells were used for SCNT to produce cloned pigs homozygous for a double GalT/CMAH KO. These results demonstrate that the combination of TALEN-encoding mRNA, in vitro selection of the nuclear donor cells and SCNT provides a robust method for generating KO pigs.
Use of quadratic models with mesh-adaptive direct search for constrained black box optimization

We consider a derivative-free optimization, and in particular black box optimization, where the functions to be minimized and the functions representing the constraints are given by black boxes without derivatives. Two fundamental families of methods are available: model-based methods and directional direct search algorithms. This work exploits the flexibility of the second type of methods in order to integrate to a limited extent the models used in the first family. Intensive numerical tests on two sets of 48 and 104 test problems illustrate the efficiency of this hybridization and show that the use of the models improves the performance of the mesh- adaptive direct search algorithm significantly.
Incentives, Opportunity Costs and Contract Design for On-farm Conservation in Ethiopia

Third BioEcon Workshop May 22 – 25, 2003 Abstract Among the in-situ and ex-situ conservation options available to conserve crop genetic resources (CGRs), on-farm conservation has recently attracted massive attention from concerned organizations. To make this option operational, placing incentives and removal of perverse incentives are believed to be crucial so that landraces of no immediate interest to farmers can be conserved. However, before placing sound incentives and designing contracts with farmers, we have to understand farmers’ motives for managing portfolio of traditional varieties and the opportunity costs they face when they are expected to use landraces. This paper empirically examines farmers’ incentives and generates the opportunity costs they are facing based on a household survey data collected from 198 sorghum growing farmers in Eastern Ethiopia. To study farmers’ incentives to maintain native varieties, we have adopted a utility-based model that considers on-farm diversity as a positive externality of farmers’ livelihood decisions. Accordingly, on-farm diversity is considered as the derived outcome of farmers’ revealed preferences subject to their concerns and constraints. Using such a framework, Poisson regression model is estimated. Opportunity costs are generated using different homogeneous treatment statistical models and further they are examined using switching regression model. As usual the paper concludes outlining the policy implications of the empirical findings to design contracts for on-farm conservation of CGRs.
Changes in spatial scale in drawing and handwriting: kinematic contributions by proximal and distal joints

The coordination of arm and hand motions was studied in tasks involving drawing and handwriting movements of different amplitudes. To this end, pen motion was recorded by means of a digitizing table, while the positions of different markers on the limb were monitored by the ELITE system. It was found that the amplitude of shoulder and elbow angular motions scales roughly with the size of the figure drawn or of the script, whereas the amplitude of wrist and finger motions is small, independent of size. Consequently, the larger the limb movement, the smaller the magnitude of the contributions by motions at distal joints relative to that at proximal joints. Furthermore, while shoulder and elbow motions are tightly coupled (constant phase relation), motions at distal joints are loosely coupled to those at the proximal joints (variable phase relation). On the other hand, motion at distal joints increases the accuracy of the movement, as indicated by the smaller variability of pen trajectories compared to that of wrist trajectories.
Application Of Rating Scale Model In Conversion Of Rating Scales' Points To The Form Of Triangular Fuzzy Numbers

Abstract A new application of fuzzy sets theory in social and economic research is a fuzzy measurement of respondents' opinions. In the subject literature fuzzy rating scales or fuzzy conversion scales are being applied. In this second case, a key stage is a choice of such parameters' values of fuzzy numbers which will best illustrate the perception of linguistic values constituting points of measurement scales. In the construction of fuzzy conversion scales the item response theory models can find an application. The transformation method of verbal categories to the form of triangular fuzzy numbers with the application of rating scale model was proposed in this article. Usefulness of a suggested approach was introduced on the basis of the analysis of selected research results on inhabitants' quality of life in one of the Lower Silesian Voivodship districts. The analysis results showed big ambiguity of particular verbal categories and, in consequence, the validity of fuzzy conversion scales application.
A Set-Theoretic Approach to Collaborative Position Location for Wireless Networks

In this work, we propose a set-theoretic approach to collaborative position location for wireless networks. The proposed method borrows the concept from the parallel projection method (PPM), originally developed for signal recovery with inconsistent convex feasibility sets, modifies and extends the technique to an iterative and distributed numerical algorithm to estimate node locations, based on incomplete and noisy internode distance estimates. We demonstrate that in the case of noncollaborative position location, the proposed method is analytically equivalent to the parallel implementation of Kaczmarz Algorithm that is guaranteed to converge to a local minimizer and thus a stationary point. For collaborative position location, the proposed iterative PPM is computationally much more efficient than existing methods such as SDP and MDS-MAP, while achieving comparable or better localization accuracy and robustness to non-line-of-sight (NLOS) bias. Finally, our proposed method can be implemented in a parallel and distributed fashion, and is scalable for large network deployment.
Delayed Ipsilateral Parenchymal Hemorrhage Following Flow Diversion for the Treatment of Anterior Circulation Aneurysms

Acute and subacute complications from the use of the Pipeline device are becoming evident. Here, the authors report delayed ipsilateral hemorrhage in 8.5% of patients with anterior circulation aneurysms treated with this device. All bleeds were distant from the treated aneurysms. All procedures were done without complications and when waking after the embolization all patients were normal. Despite this, hemorrhages occurred 1–6 days postprocedure, and were not related to aneurysm size, intraprocedural complications, or anticoagulation. BACKGROUND AND PURPOSE: The PED is a flow-diverting stent designed for the treatment of cerebral aneurysms. We report 4 cases of delayed ipsilateral IPH following the technically successful treatment of anterior circulation aneurysms with the PED. MATERIALS AND METHODS: Clinical and imaging data from all patients undergoing aneurysm treatment with the PED at 2 institutions were analyzed to assess the incidence of delayed IPH after treatment with the PED. RESULTS: A total of 66 patients (47 anterior circulation) with cerebral aneurysms underwent treatment with a PED between January 2008 and November 2010. Four patients experienced delayed periprocedural IPH, all after the treatment of anterior circulation aneurysms (8.5%, 4/47). The aneurysm size ranged from 5 to 21 mm. All IPHs occurred within the cerebral hemisphere, ipsilateral to the treated aneurysm, and were anatomically remote from the treated aneurysms. All procedures were uncomplicated, and patients emerged from general anesthesia at neurologic baseline. The hemorrhages became clinically evident between 1 and 6 days after the procedure. Two patients had unfavorable outcomes (mRS scores, 4 and 6). CONCLUSIONS: Delayed IPH may occur after the treatment of anterior circulation aneurysms with flow diverters. This complication does not seem to be restricted to a specific aneurysm subtype and does not seem to be related to an intraprocedural complication or solely attributable to DAT.
Some empirical observations on sound level properties of recorded piano tones.

Preliminary to an attempt at measuring the relative intensities of overlapping tones in acoustically recorded piano music, this study investigated whether the relative peak sound levels of recorded piano tones can be reliably inferred from the levels of their two lowest harmonics, measured in the spectrum near tone onset. Acoustic recordings of single tones were obtained from two computer-controlled mechanical pianos, one upright (Yamaha MX100A Disclavier) and one concert grand (Bösendorfer 290SE), at a range of pitches and hammer velocities. Electronic recordings from a digital piano (Roland RD250S), which were free of mechanical and sound transmission factors, were included for comparison. It was found that, on all three instruments, the levels of the lowest two harmonics (in dB) near tone onset generally increased linearly with the peak root-mean-square (rms) level (in dB) as hammer velocity was varied for any given pitch. The slope of this linear function was fairly constant across midrange pitches (C2 to C6) for the first harmonic (the fundamental), but increased with pitch for the second harmonic. However, there were two sources of unpredictable variability: On the two mechanical pianos, peak rms level varied considerably across pitches, even though the strings were struck at nominally equal hammer velocities; this was probably due to the combined effects of unevenness in hammer-string interaction, soundboard response, and room acoustics. Moreover, for different pitches at equal peak rms levels, the levels of the two lowest harmonics varied substantially, even on the electronic instrument. (ABSTRACT TRUNCATED AT 250 WORDS)
Quantization of the LTB cosmological equation

The Hamiltonian H of the Kepler-like equation of the LTB cosmological model is considered. The Schrodinger operator Ĥ obtained by canonical quantization of H, is assumed to govern the Schrodinger equation for the wave function ψ of the LTB universe. The scheme, that still depends on the arbitrary integration functions E(r), m(r) of the cosmological model, is integrated exactly. The eigenvalues of Ĥ are interpreted to give the possible values of E. For E 0 than E and m remain independent functions. The quantization scheme is extended to the cosmological LTB model with cosmological constant term where similar results are shown to hold.
The “Suite” Smell of Success

The authors use a panel of more than 1,500 New Zealand firms, from a diverse range of industries, to examine how the adoption of human resource management (HRM) practices affects firm performance. The panel is based on managerial responses to mandatory surveys of management practices in 2001 and 2005 administered by the national statistical office, linked to objective longitudinal firm performance data. The authors find that, after controlling for time-invariant firm characteristics and changes in a wide range of business practices and firm developments, a suite of general HRM practices has a positive impact on firm labor and multifactor productivity. Conversely, these practices tend to have no effect on profitability, in part because the adoption of performance pay systems raises average wages in the firm.
Single Channel Speech Music Separation Using Nonnegative Matrix Factorization with Sliding Windows and Spectral Masks

A single channel speech-music separation algorithm based on nonnegative matrix factorization (NMF) with sliding windows and spectral masks is proposed in this work. We train a set of basis vectors for each source signal using NMF in the magnitude spectral domain. Rather than forming the columns of the matrices to be decomposed by NMF of a single spectral frame, we build them with multiple spectral frames stacked in one column. After observing the mixed signal, NMF is used to decompose its magnitude spectra into a weighted linear combination of the trained basis vectors for both sources. An initial spectrogram estimate for each source is found, and a spectral mask is built using these initial estimates. This mask is used to weight the mixed signal spectrogram to find the contributions of each source signal in the mixed signal. The method is shown to perform better than the conventional NMF approach.

Dynamic Image Based CAPTCHA

Web security has become a critical and challenging issue due to the growth of Internet. BOT is one of the most malicious threats to the web services. It runs automated tasks over the internet and creates problem. One solution for securing web from BOT is to develop CAPTCHA. CAPTCHA is acronym for Completely Automated Public Turing test to tell Computers and Humans Apart. CAPTCHA may be textual or image based CAPTCHA. In this paper dynamic image based three tier CAPTCHA system is proposed. The layers are 1) Image access layer2) Image processing layer and 3) Presentation layer. The proposed system makes cracking a difficult task for BOT, but at the same time it is easier for human to perceive it. In this paper strengths and weaknesses of available image based CAPTCHAs and working steps of proposed algorithm have been discussed. It is observed that the probability of a BOT hacking the proposed prototype system is considerably low.
Application of Digital Holography for Nondestructive Testing and Metrology: A Review

Holography and holographic interferometry as a means for nondestructive testing, as well as metrologic tools in engineering, biology, and other fields, have significant momentum by the introduction of digital holography (DH) and further by the employment of numerical processing power, which became available due to the increase in speed and data capacity of modern computers. In this review paper, we present the basics of holography, holographic interferometry, and DH, and give examples from such diverse fields as deformation analysis, form determination, refractive index measurement, and wave front reconstruction by shearographic differential interference contrast microscopy.
