Does the Past Say It All? Using History to Predict Change Sets in a CMDB

To avoid unnecessary maintenance costs in large IT systems resulting from poorly planned changes, it is essential to manage and control changes to the system and to verify that all items impacted by each change are updated as needed. This paper presents a method of decision support that helps guarantee that each change set (those items to be updated in the change) contains all the software or hardware components impacted by the proposed change. Today, many IT systems are managed by a Configuration Management Database (CMDB), which can be represented as a large graph in which the nodes are configuration items (CIs), such as software applications or servers, and the edges record dependencies between these items. In this paper we present a new approach to suggesting change sets based on our conjecture that each new change set is likely to be similar to instances of previous change sets. Accordingly, if the analyst determines that CI x is in a new change set, our method essentially searches for previous change sets, stored in the CMDB, that contain x, and suggests that CIs in those sets (appropriately ranked) should be considered for inclusion in the new change set. Our model uses support and confidence measures to estimate how closely nodes x and y are related, based on how often they have appeared together in past change sets. Based on these measures, we implement a prototype that suggests likely items to an analyst who is composing a change set. Based on a history of three years of a particular industrial CMDB, and several filtering techniques, the observed recall and precision values were as high as 69.8% and 88.5% respectively.
Information models in OPC UA and their advantages and disadvantages

OPC UA is one of the most prominent candidates for a middleware in future CPS scenarios. It provides many concepts which makes it very useful to address challenges in the area of flexibility, security and availability. It offers a semantic rich information space with extensible OPC UA information models. They make it possible to develop smart client application with a high degree of flexibility. This paper summarizes experiences made with the use of OPC UA information models. Thus, it presents various projects in which we used OPC UA as base technologies. Then, we describe how information models supported the development. On the other hand, we provide a list of issues which we experienced regarding this information models. There is some potential to improve OPC UA in the area of revision management and distributed applications.
Compliance Monitoring of Third-Party Applications in Online Social Networks

With the widespread adoption of Online Social Networks (OSNs), users increasingly also use corresponding third-party applications (TPAs), such as social games and applications for collaboration. To improve their social experience, TPAs access users' personal data via an API provided by the OSN. Applications are then expected to comply with certain security and privacy policies when handling the users' data. However, in practice, they might store, use, and distribute that data in all kinds of unapproved ways. We present an approach that transparently enforces security and privacy policies on TPAs that integrate with OSNs. To this end, we integrate concepts and implementations from the research areas of data usage control and information flow control. We instantiate these results in the context of TPAs in OSNs in order to enforce compliance with security and privacy policies that are provided by the OSN operator. We perform a preliminary evaluation of our approach on the basis of a TPA that integrates with the Facebook API.
Oral lesions in paediatric patients with graft-versus-host disease.

AIM This work aims at assessing and describing the most frequent clinical manifestations of the Graft-versus- Host Disease (GvHD) in the oral and maxillofacial region in paediatric patients affected by neoplastic or non neoplastic haematologic disorders who undergo specific haematopoietic stem cell transplantation (HSCT) protocols, with a view to detecting the potential pathological modifications that are recognised as the cause of a possible altered harmonious development of the child. MATERIALS AND METHODS Thirty-eight paediatric patients aged between 3 and 13 years, coming from the haematological department of Tor Vergata University (Roma, Italy) and affected by GvHD, assessed on the basis of their medical history and accurate clinical and instrumental exams, after having received haematopoietic stem cell transplantation for neoplastic or non neoplastic haematologic disorders, were enrolled in this study. The aim of this work was to assess oral conditions, detect possible oral pathological manifestations and evaluate their incidence both locally and in terms of clinical severity, as well as to mitigate associated symptoms. This was done to prevent and eliminate any oral interference in the systemic treatment protocol. DISCUSSION AND CONCLUSION In line with the data presented in the literature, clinical GvHD manifestations seem to mainly involve the oral and maxillofacial region from an early phase also in paediatric patients. As a consequence, a timely diagnosis and a multidisciplinary treatment programme are essential for the early detection of the oral signs of potential systemic complications, to improve the quality of life of these young patients, as well as to prevent any potential alterations of dentoskeletal development and growth in the child.
In search of low-frequency and rare variants affecting complex traits

The allelic architecture of complex traits is likely to be underpinned by a combination of multiple common frequency and rare variants. Targeted genotyping arrays and next-generation sequencing technologies at the whole-genome sequencing (WGS) and whole-exome scales (WES) are increasingly employed to access sequence variation across the full minor allele frequency (MAF) spectrum. Different study design strategies that make use of diverse technologies, imputation and sample selection approaches are an active target of development and evaluation efforts. Initial insights into the contribution of rare variants in common diseases and medically relevant quantitative traits point to low-frequency and rare alleles acting either independently or in aggregate and in several cases alongside common variants. Studies conducted in population isolates have been successful in detecting rare variant associations with complex phenotypes. Statistical methodologies that enable the joint analysis of rare variants across regions of the genome continue to evolve with current efforts focusing on incorporating information such as functional annotation, and on the meta-analysis of these burden tests. In addition, population stratification, defining genome-wide statistical significance thresholds and the design of appropriate replication experiments constitute important considerations for the powerful analysis and interpretation of rare variant association studies. Progress in addressing these emerging challenges and the accrual of sufficiently large data sets are poised to help the field of complex trait genetics enter a promising era of discovery.
Cloth Tearing Simulation

Among different physical simulation topics, cloth simulation is one of the most popular subjects in computer graphics. There are many different studies published on different aspects of cloth simulation, but there are not many studies focused on the tearing of cloth. Existing studies related to this topic have only dealt with some aspects of the problem [Metaaphanon et al. 2009] and have not provided general solutions. In this study, we provide a generic solution for different aspects of the problem of tearing cloth. Some of the points we focus on in this study include: providing realistic tearing effect, preserving polygonal area consistency and texture integrity after the process of tearing, and handling the tear properly for either outer physical impacts or inner manipulations like allowing a user to drag the cloth interactively. The technique proposed in this paper works with non-uniform cloth structures. It makes it easier to adopt the solution proposed here for many different simulation systems. The processing cost of the technique is quite small, so it is also appropriate for real-time simulation systems.

Reconfigurable forward homography estimation system for real-time applications

Image processing and computer vision algorithms extensively use projections, such as homography, as one of the processing steps. Systems for homography calculation usually observe homography as an inverse problem and provide an exact solution. However, the systems processing larger resolution images cannot meet inherently tight real-time constraints. Look-up table based systems provide an option for forward homography solutions, but they require large memory availability. Recent compressed look-up table methods reduce the memory requirements at the expense of lower peak signal-to-noise-ratio. In this work, we present a forward homography estimation algorithm which provides higher image quality than compressed look-up table methods. The algorithm is based on bounding the homography error, and neglecting the pixels out of the determined bound. The presented FPGA implementation of the estimation system requires a small amount of hardware, and no memory storage. The prototype system project an image frame onto a spherical surface at 295 Mpixels/s rate which is, up to our knowledge, currently the fastest homography system.
Automatic wheeze detection based on auditory modelling

Abstract Automatic wheeze detection has several potential benefits compared with reliance on human auscultation: it is experience independent, an automated historical record can easily be kept, and it allows quantification of wheeze severity. Previous attempts to detect wheezes automatically have had partial success but have not been reliable enough to become widely accepted as a useful tool. In this paper an improved algorithm for automatic wheeze detection based on auditory modelling is developed, called the frequency- and duration-dependent threshold algorithm. The mean frequency and duration of each wheeze component are obtained automatically. The detected wheezes are marked on a spectrogram. In the new algorithm, the concept of a frequency- and duration-dependent threshold for wheeze detection is introduced. Another departure from previous work is that the threshold is based not on global power but on power corresponding to a particular frequency range. The algorithm has been tested on 36 subjects, 11 of whom exhibited characteristics of wheeze. The results show a marked improvement in the accuracy of wheeze detection when compared with previous algorithms.
Towards robust phoneme classification: Augmentation of PLP models with acoustic waveforms

The robustness of classification of phoneme segments using generative classifiers is investigated for the PLP and acoustic waveform speech representations in the presence of white Gaussian noise. We combine the strengths of both representations, specifically the excellent classification accuracy of PLP in quiet conditions with the additional robustness of acoustic waveform classifiers. This is achieved using a convex combination of their respective log-likelihoods to produce a combined decision function. The resulting combined classifier is uniformly as accurate as PLP alone and is significantly more robust to the presence of additive noise during testing. Issues of noise modelling and time-invariant classification of acoustic waveforms are also considered with initial solutions used to improve accuracy.
Localization of breathing cracks using combination tone nonlinear response

In this paper, a new nonlinear combination tone system identification technique is investigated to identify breathing crack damage in isotropic rod structures. Inspired by the combination tone phenomenon observed in the human auditory system, the difference of two harmonic excitation frequencies is utilized to detect and locate the breathing crack. The method of multiple scales is used to analyze a simplified but representative bilinear system and gain insight into the concept. An experimental investigation is performed to verify the proposed approach. Compared to previously introduced techniques for nonlinear system identification of breathing cracks using super-harmonic or sub-harmonic signals, the proposed approach is much more robust and easier to implement.
Human-Systems Integration and Air Traffic Control

Development of air traffic control decision support tools necessarily requires an iterative design process to ensure that the tool is effectively integrated into the complex and demanding operational environment. Without an iterative design process that actively incorporates user input, decision support tools fielded in the air traffic control sector could result in controller resistance to the technology and/or budget overruns caused by the need to fix problems identified by the controllers post hoc. While the usability and acceptability of a system are necessary to achieving a successful system, by themselves, these attributes are not sufficient. A highly usable and acceptable system may be unsuccessful at achieving any operational benefit (e.g., improved efficiency, improved safety). Thus, the design process should strive to interactively achieve the operational benefits expected of the system. Lincoln Laboratory used a benefits-driven, iterative, system design process for the Tower Flight Data Manager (TFDM), a prototype of an integrated decision support system for the air traffic control tower (ATCT) environment.
Unsupervised Web Topic Detection Using A Ranked Clustering-Like Pattern Across Similarity Cascades

Despite the massive growth of social media on the Internet, the process of organizing, understanding, and monitoring user generated content (UGC) has become one of the most pressing problems in today's society. Discovering topics on the web from a huge volume of UGC is one of the promising approaches to achieve this goal. Compared with classical topic detection and tracking in news articles, identifying topics on the web is by no means easy due to the noisy, sparse, and less- constrained data on the Internet. In this paper, we investigate methods from the perspective of similarity diffusion, and propose a clustering-like pattern across similarity cascades (SCs). SCs are a series of subgraphs generated by truncating a similarity graph with a set of thresholds, and then maximal cliques are used to capture topics. Finally, a topic-restricted similarity diffusion process is proposed to efficiently identify real topics from a large number of candidates. Experiments demonstrate that our approach outperforms the state-of-the-art methods on three public data sets.
Adherence to Mediterranean diet and risk of cancer: an updated systematic review and meta‐analysis of observational studies

The aim of the present systematic review and meta‐analysis of observational studies was to gain further insight into the effects of adherence to Mediterranean Diet (MD) on overall cancer mortality, incidence of different types of cancer, and cancer mortality risk in cancer survivors. Literature search was performed using the electronic databases PubMed, and EMBASE until 2 July 2015. We included either cohort (for specific tumors only incidence cases were used) or case–control studies. Study specific risk ratios, hazard ratios, and odds ratios (RR/HR/OR) were pooled using a random effect model. The updated review process showed 23 observational studies that were not included in the previous meta‐analysis (total number of studies evaluated: 56 observational studies). An overall population of 1,784,404 subjects was included in the present update. The highest adherence score to an MD was significantly associated with a lower risk of all‐cause cancer mortality (RR: 0.87, 95% CI 0.81–0.93, I2 = 84%), colorectal cancer (RR: 0.83, 95% CI 0.76–0.89, I2 = 56%), breast cancer (RR: 0.93, 95% CI 0.87–0.99, I2=15%), gastric cancer (RR: 0.73, 95% CI 0.55–0.97, I2 = 66%), prostate cancer (RR: 0.96, 95% CI 0.92–1.00, I2 = 0%), liver cancer (RR: 0.58, 95% CI 0.46–0.73, I2 = 0%), head and neck cancer (RR: 0.40, 95% CI 0.24–0.66, I2 = 90%), pancreatic cancer (RR: 0.48, 95% CI 0.35–0.66), and respiratory cancer (RR: 0.10, 95% CI 0.01–0.70). No significant association could be observed for esophageal/ovarian/endometrial/and bladder cancer, respectively. Among cancer survivors, the association between the adherence to the highest MD category and risk of cancer mortality, and cancer recurrence was not statistically significant. The updated meta‐analyses confirm a prominent and consistent inverse association provided by adherence to an MD in relation to cancer mortality and risk of several cancer types.
Horizontal ladder task-specific re-training in adult rats with contusive thoracic spinal cord injury.

PURPOSE Using the horizontal ladder task, we examined some issues that need to be resolved before task-specific rehabilitative training can be employed clinically for the frequent contusive spinal cord injury (SCI). We hypothesized that improving recovery in task performance after contusive thoracic SCI requires frequent re-training and initiating the re-training early during spontaneous recovery. METHODS Contusive SCI was produced at the adult female Sprague Dawley rat T10 vertebra. Task re-training was initiated one week later when occasional weight-supported plantar steps were taken overground (n = 8). It consisted of 2 repetitions each day, 5 days each week, for 3 weeks. Task performance and overground locomotion were assessed weekly. Neurotransmission through the SCI ventrolateral funiculus was examined. SCI morphometry was determined. RESULTS Re-training did not improve task performance recovery compared to untrained Controls (n = 7). Untrained overground locomotion and neurotransmission through the SCI did not change. Lesion area at the injury epicenter as a percentage of the total spinal cord area as well as total tissue, lesion, and spared tissue, white matter, or gray matter volumes did not differ. CONCLUSIONS For the horizontal ladder task after contusive thoracic SCI, earlier re-training sessions with more repetitions and critical neural circuitry may be necessary to engender a rehabilitation effect.
Nicotinic receptor subunit mRNA in the thalamus of the rat: relevance to schizophrenia?

Recent evidence suggests that aberrant nicotinic receptor (nAChR) expression plays an important role in schizophrenia. The present study sought to examine the distribution of nAChRs within the thalamus and associated cholinergic structures by examining nAChR subunit mRNA expression using in situ hybridization histochemistry. Transcripts for α4 and β2 subunits were found in high levels in all thalamic nuclei and at lower levels in cholinergic nuclei (PPTg and MS/VDB). Distribution of mRNA encoding for additional subunits was restricted; lower β3 subunit transcript levels were detected in the anterior thalamic nuclei and portions of the lateral and posterior thalamic nuclei, with α7 transcripts being detected in cholinergic nuclei, the IMD and very low levels in the RTN. Low levels of α6 and β3 transcript were found only within the RTN.
Low-power 6-bit flash ADC for high-speed data converters architectures

The design of low-power, medium resolution flash converter is presented. The goal is to provide a basic cell with state-of-the art figure of merit thus permitting low-power data converter architectures with a more flexible use of flash ADC cells. The designed 6-bit flash uses interpolation and V/I converters that operate as preamplifier stage of latches. Circuit simulations show a figure of merit as low as 1.2 pj/conv-lev at 100-MS/s sampling frequency and 3.3-V analog supply voltage
Person-oriented Conception of Happiness: Between Freud, Jung and Maslow

Abstract: We develop a person-oriented conception of happiness (POCH), which is based on the ideas of systemic approach. We demonstrate that the conception can be considered as a powerful personality theory, which integrates the conceptions of Z. Freud, C. Jung, A. Maslow and some other scientists. We show how to solve several important problems of modern psychology within POCH, and outline perspectives of the further investigations.

Accretion and star formation rates in low‐redshift type II active galactic nuclei

Accretion and star formation (SF) rates in low-redshift Sloan Digital Sky Survey type II active galactic nuclei (AGN) are critically evaluated. Comparison with photoionization models indicates that bolometric luminosity (L bol ) estimates based on L([O III] λ5007) severely underestimate L bol in low-ionization sources such as LINERs. An alternative method based on L(Hβ) is less sensitive to the ionization level, and a novel method, based on a combination of L([O III] λ5007) and L([O I] λ6300), is perhaps the best. Using this method, I show that low-ionization AGN are accreting faster than assumed until now. Other significant related findings are as follows. (1) Any type II AGN property related to the black hole (BH) mass is more reliably obtained by removing blue galaxies from the sample. (2) Seyfert 2s and LINER 2s form a continuous sequence of L/L Edd with no indication for a change in accretion mechanism or mode of mass supply. There are very few, if any, LINERs in all type I samples which results in a much narrower L/L Edd distribution compared with type II samples. (3) There is a strong correlation between the SF luminosity, L SF , and L bol over more than five orders of magnitude in luminosity. This leads to a simple relationship between bulge and BH growth rates, g( bul g e )/g(BH ) ∝ L -0.2 bol , where g( bulge )/g(BH) = 115 for L bol = 10 42 erg s -1 . Seyfert 2s and LINER 2s follow the same L SF -L bol correlation for all sources with a stellar age indicator, D n 4000, smaller than 1.8. This suggests that a similar fraction of SF gas finds its way to the centre in all AGN. (4) L bol , L sF , L/L Edd and the specific SF rate follow D n 4000 in a similar way.
