An Interpretable SVM Classifier by Discrete-Weight Optimization

The main problem investigated in this paper is to learn ”interpretable” linear classifiers from data. Interpretable models are captured using ”discrete” linear functions. The learning problem is formulated as minimizing the cumulative zero-one loss of a discrete hyperplane, penalized by the standard L2 regularizer. This learning task is cast as a MILP problem, and solved using convex relaxation and rounding. Experiments on both synthetic and real-world datasets corroborate the interest of this approach. We benchmarked the proposed method against two classifiers: iDILSVM a discrete version of SVM based a hinge-loss and iithe traditional linear L1-norm SVM. Our algorithm outperforms DILSVM on several datasets in terms of accuracy and computational efficiency. It has close performance to the continuous SVM. These results suggest that the proposed classifier provides a good trade-off between performance and interpretability.

Hypoxia-regulated p53 and its effect on radiosensitivity in cancer cells

Purpose: To determine the response of tumor suppressor p53 to hypoxia in different tumor cell lines and the involvement of p53 activity regulation in the effect of hypoxia on tumor cell sensitivity to radiation and hyperthermia. Materials and methods: Three tumor cell lines with functional p53 were treated with chronic or cyclic hypoxia followed by radiation or hyperthermia to investigate p53 activity and cell survival. Flow cytometry was used to investigate the effect of hypoxia-induced cell cycle arrest on radiosensitivity in KHT-C (mouse fibrosarcoma) cells. Transient transfection was performed to determine the role of altered p53 activity in KHT-C and SCC VII (mouse squamous-cell carcinoma) radiosensitivity. Results: Aerobic radiosensitivity was decreased in KHT-C and SCC VII cells after in vitro chronic or cyclic hypoxia pretreatment, but in HT1080 cells, it was slightly increased after chronic hypoxia, and was unchanged after acute hypoxia pretreatment. Decreased radiosensitivity in hypoxia-pretreated KHT-C and SCC VII cells was unlikely due to hypoxia-induced cell cycle arrest, but rather seemed to be associated with increased expression of Mdm2 (mouse double minute-2) and decreased p53. Furthermore, hypoxia pretreatment inhibited the activation of p53 by radiation. Similar results were observed in hyperthermia treated KHT-C cells. Finally, decreased radiosensitivity was observed in both KHT-C and SCC VII cells transiently transfected with Mdm2 or anti-sense p53 cDNA. Conclusion: We demonstrated that hypoxia may decrease tumor cell radiosensitivity through the suppression of p53 activity in some tumor cell lines. These results suggested the response of p53 to hypoxia can be cell type specific and contribute to radiosensitivity of hypoxic cells.
A new statistical approach for the automatic segmentation of continuous speech signals

A statistical approach for the segmentation of a continuous speech signal to detect acoustic events is presented. Experiments are carried out to test the segmentation algorithms. Reasonable results are obtained with speech signals, although these are not exactly piecewise stationary. A comparison between the experimental results of automatic and handmade segmentations, demonstrates the potential acoustic-phonetic classification capability of the proposed algorithms. >

Quality of in-hospital cardiac arrest calls: a prospective observational study

Objective To determine the quality and diagnostic accuracy of in-hospital adult clinical emergency calls. Design Prospective observational study. Setting Three National Health Service acute hospitals in England. Participants Adult patients sustaining an in-hospital cardiac arrest (CA) or medical emergency (ME) which required activation of the hospital resuscitation team between 1 December 2009 and 30 April 2010. Main outcome measures Emergency call duration, emergency team dispatch time, diagnostic accuracy of emergency call (sensitivity/specificity), thematic analysis of emergency call, patient outcomes (return of spontaneous circulation and survival to hospital discharge). Results There were 426 adult resuscitation team activations. There was variability in emergency call duration ranging from 6 to 92 s (median 15 s; IQR 12–19). The sensitivity and specificity of calls for a CA was 91% (86.4–94.6%) and 62% (55.5–68.7%), respectively. Sensitivity did not change with call duration but specificity increased from 38% (25.8–51.0%) for the shortest calls to 82% (69.5–89.6%) for longer calls; p=0.03. The return of spontaneous circulation rate was 38% for calls when the patient was confirmed as in CA upon arrival of the resuscitation team. Survival to hospital discharge rates was higher in patients with shorter call durations (26%) than calls with longer call duration (12%); p=0.028. Five themes emerged identifying reasons for the increased call delay. Conclusion There is variability in duration and diagnostic accuracy of in-hospital emergency calls. This is associated with delayed activation of the emergency response. The attempt to differentiate between ME and CA is a source of confusion. A single clinical emergency response for CA and ME calls may provide a more focused and timely emergency response.
Human exposure to pulsed current waveforms below 100 kHz

A tool for the analysis below 100 kHz of pulsed current waveforms with reference to human exposure has been developed. It consists of a dedicated program written in Matlab. As input data, a trapezoidal pulsed current waveform has been considered, and, varying the rise time and the duty-cycle, a parametric analysis has been performed. Also a noise superimposed to the signal has been considered. Parameters relevant to human exposure have been calculated following the ICNIRP Guidelines. A schematic operative diagram for metal inert gas welding applications is proposed; an experimental set-up has been built and the obtained results are reported.
A User-Oriented Test Environment Based on User-Interface Evaluation Graphical Controls

Abstract Several user-oriented techniques have been proposed for Graphical User Interface evaluation. In this paper, we focus on User-Oriented Test concepts, advantages and related problems. Among the User-Oriented Test techniques, the electronic informer is a powerful technique for interactive system testing. Thus, this research paper contributes in the improvement of existing tools for interactive system evaluation. This environment is achieved using (1) an electronic informer dedicated to the interactive system evaluation and (2) evaluation based graphical controls. The proposed evaluation environment is structured following client-server architecture. It aims to automate the interactive system evaluation process. Besides it takes the evaluation process into account since early interactive system design phases. This environment is validated by an experimental test.
The role of the pro‐sequence in the processing and secretion of the thermolysin‐like neutral protease from Bacillus cereus

The Bacillus cereus cnp gene coding for the thermolysin‐like neutral protease (TNP) has been cloned, sequenced, and expressed in Bacillus subtilis. The protease is first produced as a pre‐pro‐protein (Mr= 61000); the pro‐peptide is approximately two‐thirds of the size of the mature protein. The pro‐sequence has been compared with those of six other TNPs, and significant homologies have been found. Additionally, the TNP pro‐sequences are shown to be homologous to the pro‐sequence of Pseudomonas aeruginosa elastase. A mutant has been constructed from cnp, in which 23 amino acids upstream from the pro‐protein processing site have been deleted. This region has no homologous analogue in any of the other TNP pro‐sequences. The detection results in a delay of six to eight hours in detection of active protease in the growth medium, as well as a 75% decrease in maximum protease production. N‐terminal analysis of the mutant mature protein demonstrates that the processing site is unaltered by the pro‐sequence deletion. The deletion must, therefore, modulate the kinetics of processing and/or secretion of the pro‐protein.
Texting, textisms and teaching Portuguese

espanolEste estudio analiza la percepcion de la norma del portugues digital y su relacion con la ensenanza de la lengua portuguesa como L1 y L2. 85 estudiantes de grado de educacion y comunicacion participaron en el estudio a traves de un cuestionario de 35 items, validado tanto en el plano teorico como en el empirico. El analisis cualitativo de los resultados mostro un elevado rechazo al uso de textismos del plano grafico y fonologico que se asocian a errores ortograficos del portugues estandar. Sin embargo, los elementos multimodales del portugues digital se aceptaron como recursos para la ensenanza de esta lengua. EnglishThis study examines the perception of digital Portuguese spelling and its relationship to the teaching of Portuguese as L1 and L2. 85 undergraduate and graduate students in the fields of education and communication participated in the study through a 35-item questionnaire, validated in both theoretical and the empirical terms. The qualitative analysis of the results showed a high rejection of the use of textisms at the graphic and phonological levels, which are regarded as being associated with standard Portuguese spelling mistakes. However, the multimodal elements of digital Portuguese were accepted as resources for the teaching of the language.
Anaerobic work calculated in cycling time trials of different length.

UNLABELLED Previous research showed that gross efficiency (GE) declines during exercise and therefore influences the expenditure of anaerobic and aerobic resources. PURPOSE To calculate the anaerobic work produced during cycling time trials of different length, with and without a GE correction. METHODS Anaerobic work was calculated in 18 trained competitive cyclists during 4 time trials (500, 1000, 2000, and 4000-m). Two additional time trials (1000 and 4000 m) that were stopped at 50% of the corresponding "full" time trial were performed to study the rate of the decline in GE. RESULTS Correcting for a declining GE during time-trial exercise resulted in a significant (P<.001) increase in anaerobically attributable work of 30%, with a 95% confidence interval of [25%, 36%]. A significant interaction effect between calculation method (constant GE, declining GE) and distance (500, 1000, 2000, 4000 m) was found (P<.001). Further analysis revealed that the constant-GE calculation method was different from the declining method for all distances and that anaerobic work calculated assuming a constant GE did not result in equal values for anaerobic work calculated over different time-trial distances (P<.001). However, correcting for a declining GE resulted in a constant value for anaerobically attributable work (P=.18). CONCLUSIONS Anaerobic work calculated during short time trials (<4000 m) with a correction for a declining GE is increased by 30% [25%, 36%] and may represent anaerobic energy contributions during high-intensity exercise better than calculating anaerobic work assuming a constant GE.
Grey-Level Cooccurrence Matrix Performance Evaluation for Heading Angle Estimation of Moveable Vision System in Static Environment

A method of extracting information in estimating heading angle of vision system is presented. Integration of grey-level cooccurrence matrix (GLCM) in an area of interest selection is carried out to choose a suitable region that is feasible for optical flow generation. The selected area is employed for optical flow generation by using Horn-Schunck method. From the generated optical flow, heading angle is estimated and enhanced via moving median filter (MMF). In order to ascertain the effectiveness of GLCM, we compared the result with a different estimation method of optical flow which is generated directly from untouched greyscale images. The performance of GLCM is compared to the true heading, and the error is evaluated through mean absolute deviation (MAE). The result ensured that GLCM can improve the estimation result of the heading angle of vision system significantly.
Professionele zelfreflectie in de Nederlandse journalistiek

Journalist is een vrij beroep. Toch werken de meeste journalisten aan de hand van gedeelde normen en waarden en een gevoel van verbondenheid met het vak, waardoor de journalistiek steeds meer professionaliseert. Desondanks klinken er vanuit de maatschappij en vanuit de journalistiek zelf kritische geluiden. Zo heeft journalist Joris Luyendijk gezegd dat het onmogelijk is om 100% objectief verslag te doen vanuit dictatoriale landen. Hier maakte Luyendijk zich niet heel populair bij collega-journalisten, die vinden dat hij het vertrouwen in het vak ondermijnt. Een andere kritische journalist Nick Davies, zegt dat het door de commercialisering en de daarbij horende concurrentiestrijd onmogelijk is om de waarheidsclaim van de journalistiek waar te maken. Twee kritieken, twee verschillende oorzaken. Alleen de kritiek van Luyendijk voegt echt wat toe aan de fundamentele discussie over de journalistiek, omdat hij de oorzaak binnen de beroepsgroep zoekt. Maar hoe kijken de andere journalisten hiertegen aan? In een aantal tv-series van de Nederlandse publieke omroep reflecteren journalisten op diverse gebeurtenissen in hun vakgebied. In deze masterscriptie is onderzoek gedaan naar de professionele zelfreflectie van Nederlandse journalisten door drie van deze tv-series waarin journalisten uitgebreid worden geinterviewd te analyseren. Met als doel het inzichtelijk maken van hun kritiek op de journalistiek, wat aan die kritiek ten grondslag ligt en of hun kritieken op constructieve wijze bijdragen aan een fundamentele discussie over de journalistiek. Door een kwalitatieve thematische analyse uit te voeren op de transcripten van de tv-interviews zijn er vier discussiethema’s ontdekt. Deze discussiethema’s zijn: 1. vertrouwenscrisis door externe factoren, 2. digitale werkelijkheid, 3. vertrouwenscrisis door interne factoren en 4. de veranderde verhoudingen tussen publiek, media en politiek. Het meest opvallende is dat de meeste journalisten in de tv-series de snelheid van het internet en de moordende concurrentie de schuld geven voor het feit dat zij niet kunnen voldoen aan de journalistieke normen en waarden. Ze wijzen dus naar machten buiten de journalistiek. In de hele dataset is er maar een enkele journalist geweest die de werking van de journalistieke normen en waarden zelf bekritiseert. De tegenstrijdigheden binnen de journalistieke normen en waarden blijven dus doorgaans buiten schot. Hieruit kan geconcludeerd worden, dat de Nederlandse journalist zich in de tv-series van de NPO minimaal voegt in een fundamentele discussie over de journalistiek, zoals Luyendijk dat wel heeft gedaan.
A framework for developing better instruments to measure web based health information quality

With the Internet becoming a growing source of health information, evaluating the quality of the webbased health information is essential. A number of consumer-oriented instruments were designed to assess the quality of health information. However, existent tools are incomprehensive, unvalidated, not easy to use, and difficult to understand. The main objective of this study is to provide a framework for systematically developing validated and usable instruments to evaluate the quality of web-based health information. The framework incorporates item-to-total correlation and factor analysis. Next, weighting scores for the quality criteria are assigned based on the application of the Kano model to classify quality criteria as basic, performance or attractive. The development process ends with testing the instrument in terms of its usability, readability, reliability and validity. Among the implications and contributions of this research is improving the quality of the evaluation instruments and making the process of developing assessment tools more standardized and transparent.
Differences between KT/V Measured during Dialysis and KT/V Predicted from Manufacturer Clearance Data

We retrospectively analyzed data from 3,863 dialysis treatments in 329 end-stage renal disease patients over a period of 33 months to evaluate the accuracy of in vitro KT/V estimated by manufacturer's urea clearance data in relation to in vivo measured KT/V. In 1,087 urea clearances measured, mean actual clearance was 87% of predicted. At all blood flows, actual clearances were significantly lower than predicted (8-16% lower than predicted). In 2,807 KT/V measurements, predicted KT/V was 1.238 ± 0.005 whereas the mean of actual measured KT/V was 16% lower or 1.024 ± 0.005 (P < 0.0001). At different blood flows and with different dialyzers, predicted KT/V overestimated actual values. With increasing numbers of reuse, actual/predicted clearance ratios and actual/predicted KT/V ratios progressively dropped. Prescribing dialysis treatments using manufacturer's in vitro generated clearance data can lead to marked underdialysis of patients.

The evaluation of digital panoramic radiographs taken for implant dentistry in the daily practice.

OBJECTIVES This study was conducted 1/ to find out the effects of anatomical sites and implant types on the magnification and 2/ to evaluate the inter-observer variability on the evaluation using the digital panoramas taken at daily practices. STUDY DESIGN Panoramic radiographs from 156 patients treated with implants were evaluated by three observers. The length was measured on the lateral aspect of the implant in 1:1 mode using image measurement program and the percent magnification was calculated. The inter-observer correlation coefficient was measured to express inter-observer variability using reliability analysis-scale. RESULTS The average magnification factor in the panoramic radiograph was 126.8 % in the vertical plane. Location within the anatomic arch showed different magnification by a minimum of 119.4 to a maximum of 130.8 %. The measurements among three examiners were well correlated showing correlation coefficient of 0.81. The differences between one side from the contralateral side was evaluated and it was shown that the differences were observed only seen maxillary anterior and upper premolar regions. Additionally, the external non-submerged group had the highest magnification value. CONCLUSIONS Digital panoramic radiographs showed sufficient accuracy and good inter-examiner agreement. The radiographic magnification of implant length was influenced by anatomical sites and implant types.

An integrated vulnerability-based detection / interception model for the protection of regional infrastructure from covert attack

The expanse of U.S. transportation systems has helped to facilitate persistent national economic growth, its ease of access and reliability vital to the plethora of users who utilize daily the established infrastructure. Recent events have shown cause for concern, however, as the vulnerability inherent in such transportation systems has been exploited by the calculated attacks of highly motivated individuals and groups who have used these networks to target the connected critical infrastructure and human populations. This paper introduces a modified shortest path network interdiction formulation for the placement on detection sensors within a geographic region of interest in lieu of direct placement (or interdiction) of network arcs to assess regional network vulnerability. An integrated interception team model uses these resource location results to allocate interception units on the network and analyze their effectiveness in responding to generated sensor alarms. The p-Median problem and hypercube spatial queuing model are adapted to locate units and assess interception performance respectively. A demonstrative case analysis is offered for the region of Lancaster – Palmdale, CA.
Thinking Outside the Box: Spatial Anticipation of Semantic Categories

For certain applications like autonomous systems it is insufficient to interpret only the observed data. Instead, objects or other semantic categories, which are close but outside the field of view, need to be anticipated as well. In this work, we propose an approach for anticipating the semantic categories that surround the scene captured by a camera sensor. This task goes beyond current semantic labeling tasks since it requires to extrapolate a given semantic segmentation. Using the challenging Cityscapes dataset, we demonstrate how current deep learning architectures are able to learn this extrapolation from data. Moreover, we introduce a new loss function that prioritizes on predicting multiple labels that are likely to occur in the near surrounding of an image.
