An Immunization Framework for Social Networks Through Big Data Based Influence Modeling

Social networks are critical in terms of information or malware propagation. However, how to contain the spreading of malware in social networks is still an open and challenging issue. In this paper, we propose a novel defending method through big data based influence modeling. We first establish a social interaction graph based on big data sets of the studied object. Based on the graph, we are able to measure direct influence of individuals by computing each node's strength, which includes the degree of the node and the total number of messages sent by each user to her friends. Then, we design an algorithm to construct influence spreading tree using the breadth first search strategy, and measure indirect influence of individuals by traversing the tree. We identify the top <inline-formula><tex-math notation="LaTeX">$k$</tex-math><alternatives><mml:math><mml:mi>k</mml:mi></mml:math><inline-graphic xlink:href="peng-ieq1-2731844.gif"/></alternatives></inline-formula> influential nodes among all the nodes via the social influence strength, and propose an immunization algorithm to defend social networks against various attacks. The extensive experiments show that influence can spread easily in social networks, and the greater the influence of initial spread node is, the more impact it is on the malware propagation in social networks. The proposed method provides an effective solution to the prevention of malware or malicious messages propagation in social networks.

The TPS screw implant system is a predictable, cost-effective means by which patients can be restored in an outpatient setting. The TPS screw system has demonstrated a 94 per cent rate of success in 484 patients with 1739 implants from four countries.
MUMIS -- Advanced information extraction for multimedia indexing and searching

This paper describes the role advanced natural language processing (NLP) and especially information extraction (IE) can play for multimedia applications. As an example of such an application, we present an approach dealing with the automatic conceptual indexing of multimedia documents, which subsequently can be searched by semantic categories instead of key words. A novelty of the approach is to exploit multiple sources of information relating to video content. In the MUMIS scenario, the source of information consists in a rich range of textual and transcribed sources covering soccer games.
Individualized Cardiovascular Risk Assessment

Cardiovascular diseases (CVD) are the main cause of death and disease burden in Europe. 48% of all deaths are from CVD: 54% of deaths in women and 43% of death in men. CVD is the main cause of death for women in Europe and also for men except France, the Netherlands and Spain (Allender et al., 2009) (Figure l). Coronary heart disease (CHD) itself is the single most common cause of death in Europe, which is followed by stroke. Overall CVD is estimated to cost EU economy €192 billion a year (Allender et al., 2009).
A Review of Literature Reports of Clickers Applicable to College Chemistry Classrooms

The use of clickers (also referred to as Audience Paced Feedback, Classroom Communication Systems, Personal Response Systems, Electronic Voting Systems, Student Response Systems, Audience Response Systems, voting-machines, and zappers) has grown in college chemistry classrooms within the last decade. This review summarizes the pedagogic applications of research on clickers as well as insights from their practical use. Fifty-six publications reporting on the use of clickers in college-level science classrooms are categorized as practical application or research studies, and reviewed. Publications on the practical use of clickers suggest that students have a positive attitude towards the technology and that many benefits and few drawbacks are associated with its use. Research studies show that the use of clickers results in measurable increases in student learning in some cases and inconclusive results in other cases. In every published report of student improvement with the use of clickers, the course included student collaboration of some form.
Incentives Model in P2P Network Based on Game Theorey

Peer-to-peer (P2P) networks are self-organizing, distributed systems, with no centralized authority or infrastructure. Because of thevoluntary participation, the availability of resources in a P2P system can be highly variable and unpredictable. This paper uses ideas from gametheory to study the interaction of peers, and proposes a differential service-based incentive scheme to improve the system’s performance.
Shot detection based on dominant region tracking

The paper presents a novel video shot detection method based on dominant region tracking. The basic idea is that a shot boundary decision is made when tracked dominant regions are lost and/or new dominant regions occur. The tracking is based on region mapping between consecutive frames and performed on the MPEG DC sequence, which greatly accelerates the process. The dominant regions are obtained using a fast static image segmentation method. As a whole, the shot detection algorithm is effective and very fast.
Multiple Features Image Fusion Based on Visual Dictionary

It has been heavy work that to find the related pictures form Internet without annotation. Therefore, the automatic image annotation was extremely important in image retrieval. The traditional method were translated image visual feature into keywords simply, but it ignored the image similarity problem between the low-level visual features and high-level semantic. That is image "gap" problem, so image annotation was very lower. This paper puts forward a classification of web based image content automatic tagging mixing technology, the first it will map visual feature of image to one or more rough images, then we will preprocess the web page text information, finally we select some keywords similarity as image annotation by using similar semantic processing module. So it realizes the image and text combining the automatic annotation and it achieve high precision of image annotation.
Variação da pressão intraocular após teste submáximo de força no treinamento resistido

ABSTRACT Purpose: To verify the intraocular pressure (IOP) after sub-maximal strength test. Methods: 145 Physical Educationfreshmen (22.04 ± 4.17 years old; female and male) from Supe-rior Physical Education School of Jundiai (ESEFJ) were eva-luated in an observacional study. The exclusion criteria were:media opacity and eyeball absence or changes. All subjectsagreed to take part in this research and signed up the InformedConsent. IOP was measured by Perkins tonometer: i) pretest:just before the submaximal strength test performance and ii)post-test: immediately after the strength test. The strength testconsisted in the one-repetition-maximum-assessment throughrepetition until fatigue. Resistance training exercises such asbench press, pulley dorsal high, shoulder press, arm curl andleg press 45o were performed. Statistical analyses were obtai-ned through paired Student’s “t” test. Results: Decrease ofIOP was observed after the strength test: 13.48 ± 3.32 vs.10. 20 ±3.72 (p<0.001) in the right eye and 13.13 ± 3.96 vs.9. 74 ± 3.33(p<0.001) in the left eye.
Neuroborreliosis: pathogenesis, symptoms, diagnosis and treatment

Lyme disease is the most common human tick-borne disease in the northern hemisphere. This article describes the current knowledge of several aspects of Lyme neuroborreliosis. The epidemiology is reviewed first, with special respect to the difference between European and American disease. Then, the current knowledge about the pathogenesis of Lyme neuroborreliosis is presented, with emphasis on immune evasion strategies. Furthermore, the clinical picture of acute Lyme neuroborreliosis and the frequently discussed post-Lyme disease syndrome are critically discussed. The commonly used diagnostic strategies, as well as the relevance of the lymphocyte transformation test, CD57+/CD3- cell count and CXCL13, are presented. Finally, the therapeutic options are described to give a balanced overview of all aspects of this disease.
Abstract 2702: WAVE3 regulates NFκB signaling and sensitizes cancer cells to apoptosis and cell death driven by TNFα.

ABSTRACT WAVE3, a member of actin nucleation proteins promotes cancer invasion and metastasis, in part through regulation of expression and activity of key matrix metalloproteinases (MMPs) MMP9, which is centrally involved in invadopodia-mediated degradation of the extracellular matrix (ECM). MMP9 is also a major NFκB target gene, suggesting a potentially important role of WAVE3 in this pathway. Mechanistically, we found that loss of WAVE3 in cancer cells leads to significant inhibition of TNFα-induced NFκB activation as a result of de-stabilization of the IκBα-NFκB complex. Conversely, overexpression of WAVE3 was sufficient to enhance NFκB activity by stabilizing the IκBα-NFκB complex. We used both pharmacological and genetic manipulations of NFκB effector molecules and identified IKKβ but not IKKα as the primary upstream target for WAVE3-mediated regulation of NFκB activity. We also showed that loss of WAVE3 resulted in a significant inhibition of TNFα-mediated MMP9 expression and activity. Loss of WAVE3 also sensitized cancer cells to TNFα-driven apoptosis and cell death. Finally, we showed that either the basic rich (BR) or the proline rich (PR) domain of WAVE3 is sufficient to modulate NFkB signaling. Our results identify a novel function of WAVE3 in NFκB signaling, where its activity is essential for the stabilization of NFκB complex that promotes the metastatic phenotype of cancer cells. Therefore, therapeutic targeting of WAVE3 may prove beneficial for preventing or reducing the metastatic burden in cancer patients.

Ridge-line optimal detector

Image processing techniques have seen many developments in recent years. Starting from the pioneering work of Canny, Deriche developed a second order recursive filter capable of detecting stepped contours. However, there are other contour shapes that those filters struggle to detect. We describe a new optimal filter sensu Canny for detecting ridge-line contours. This is a third order recursive and even filter. It is dependent on three parameters by which detection accuracy is adjusted. The results obtained by applying this filter to (possibly noise- affected) images are compared with those in the work by Ziou. © 2000 Society of Photo-Optical Instrumentation Engineers.

Significance of Ventricular Myocytes and Nonmyocytes Interaction During Cardiocyte Hypertrophy

Background In cardiac hypertrophy, both excessive enlargement of cardiac myocytes and progressive interstitial fibrosis are well known to occur simultaneously. In the present study, to investigate the interaction between ventricular myocytes (MCs) and cardiac nonmyocytes (NMCs), mostly fibroblasts, during cardiocytes hypertrophy, we examined the change in cell size and gene expression of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) in cultured MCs as markers for hypertrophy in the neonatal rat ventricular cardiac cell culture system. Methods and Results The size of cultured MCs significantly increased in the MC-NMC coculture. Concomitantly, secretions of ANP and BNP into culture media were significantly increased in the MC-NMC coculture compared with in the MC culture (with the possible contamination of NMC <1% of MC). Moreover, in the MC culture, enlargement of MC and an increase in ANP and BNP secretions were induced by treatment with conditioned media of the NMC culture. A consi.
The Role of Antioxidant Supplementation in Male Infertility

With 15% of all child-bearing age couples facing infertility, up to 80 million people are currently affected worldwide. [1] One in two of these cases can be attributed to malefactors. [1] Pathologies, such as varicocele, cryptorchidism, and hypogonadism, are often easily identifiable causes; however, in approximately a quarter of the cases, no definable source is found. [1] This idiopathic infertility is often categorized by abnormalities in sperm morphology, motility, and concentration. [1] These irregular findings are characterized as teratospermia, asthenospermia, and oligospermia, respectively.
MCS-RF: mobile crowdsensing–based air quality estimation with random forest

It is a great challenge to offer a fine-grained and accurate PM2.5 monitoring service in urban areas as required facilities are very expensive and huge. Since PM2.5 has a significant scattering effect on visible light, large-scale user-contributed image data collected by the mobile crowdsensing bring a new opportunity for understanding the urban PM2.5. In this article, we propose a fine-grained PM2.5 estimation method based on random forest with data announced by meteorological departments and collected from smartphone users without any PM2.5 measurement devices. We design and implement a platform to collect data in the real world including the image provided by users. By combining online learning and offline learning, the method based on random forest performs well in terms of time complexity and accuracy. We compare our method with two kinds of baselines: subsets of the whole data sets and six classical models (such as logistic, naive Bayes). Six kinds of evaluation indexes (precision, recall, true-positive rate, false-positive rate, F-measure, and receiver operating characteristic curve area) are used in the evaluation. The experimental results show that our method achieves high accuracy (precision: 0.875, recall: 0.872) on PM2.5 estimation, which outperforms the other methods.
In-network evaluation of mobile handset performance

This paper investigates the use of the measurement reports transmitted on the Abis interface of the GSM network for evaluating handset performance. The most important advantage of this method, is the relatively easy access to a large number of calls made by many different users in the environments where handsets are expected to work. A measurement campaign was carried out where controlled calls were made by 12 users in two different environments and with 4 different commercially available handsets. The calls were made to a normal GSM network where data logging equipment was connected to the Abis. Large differences were found in the performance of the handsets. For example, the link loss was found to vary 14 dB from user to user for one handset, while for another it only varied about 5 dB under the same conditions.

Disappearing Cryptography: Information Hiding: Steganography and Watermarking

Cryptology is the practice of hiding digital information by means of various obfuscatory and steganographic techniques. The application of said techniques facilitates message confidentiality and sender/receiver identity authentication, and helps to ensure the integrity and security of computer passwords, ATM card information, digital signatures, DVD and HDDVD content, and electronic commerce. Cryptography is also central to digital rights management (DRM), a group of techniques for technologically controlling the use of copyrighted material that is being widely implemented and deployed at the behest of corporations that own and create revenue from the hundreds of thousands of mini-transactions that take place daily on programs like iTunes. This new edition of our best-selling book on cryptography and information hiding delineates a number of different methods to hide information in all types of digital media files. These methods include encryption, compression, data embedding and watermarking, data mimicry, and scrambling. During the last 5 years, the continued advancement and exponential increase of computer processing power have enhanced the efficacy and scope of electronic espionage and content appropriation. Therefore, this edition has amended and expanded outdated sections in accordance with new dangers, and includes 5 completely new chapters that introduce newer more sophisticated and refined cryptographic algorithms and techniques (such as fingerprinting, synchronization, and quantization) capable of withstanding the evolved forms of attack. Each chapter is divided into sections, first providing an introduction and high-level summary for those who wish to understand the concepts without wading through technical explanations, and then presenting concrete examples and greater detail for those who want to write their own programs. This combination of practicality and theory allows programmers and system designers to not only implement tried and true encryption procedures, but also consider probable future developments in their designs, thus fulfilling the need for preemptive caution that is becoming ever more explicit as the transference of digital media escalates. * Includes 5 completely new chapters that delineate the most current and sophisticated cryptographic algorithms, allowing readers to protect their information against even the most evolved electronic attacks. * Conceptual tutelage in conjunction with detailed mathematical directives allows the reader to not only understand encryption procedures, but also to write programs which anticipate future security developments in their design. * Grants the reader access to online source code which can be used to directly implement proven cryptographic procedures such as data mimicry and reversible grammar generation into their own work.
Complementary aspects of topological maps and time delay neural networks for character recognition

A study comparing a back propagation-like network integrating feature selection notions introduced in neocognitron networks with a supervised learning algorithm, based on Kohonen's self-organizing feature maps, is presented. The two methods are applied to handwritten zipcode recognition. The results achieved by the networks are reported using common training and test sets. The complementary aspects of these networks and possible cooperative schemes are discussed. It is shown that the performance obtained, even with a very simple cooperation scheme, significantly exceeds those of the networks working separately. <<ETX>>
OC70: Mild ventricolomegaly: should the cut‐off be lowered to 9.5 mm?

Objectives: Persisting pregnancy of unknown location (PPUL) remains a controversial clinical problem with no consensus on diagnosis or management. Biochemically, these behave like ectopic pregnancies (EP) or sick intrauterine pregnancies (IUPs). Many clinicians perform laparoscopy with dilatation and curettage (D&C) to exclude these and subsequently treat with systemic methotrexate (MTX). The aim of this study was to define this challenging group of PULs and to achieve guidelines for the management of PPUL. Methods: This retrospective analysis included pregnancies in the interval 2001–2006. All women who had PUL on transvaginal scan (TVS) were followed up with serial human chorionic gonadotrophin (hCG) levels and TVS until the eventual outcome of the pregnancy was established. Conventional PUL outcomes included failing PUL, IUP and EP. Where the location of pregnancy was never visualized on TVS, and when hCG levels reached a plateau on three or more consecutive measurements, the diagnosis of PPUL was made. All PPUL cases were collected retrospectively from the Early Pregnancy Unit database and management was analyzed. Results: Some 3050 PUL were studied; 42 (1.3%) of these were diagnosed as PPUL. At initial presentation, the median gestational age was 42 (range, 17–73) days and median initial hCG was 180 (range, 39–1491) IU/mL. Management included laparoscopy in 5/42(12%) women to exclude EP, and two had D&C. No EPs were found at the time of laparoscopy and no chorionic villi discovered at D&C. All 42 women received systemic MTX, with two women requiring two doses. There were no adverse outcomes. Conclusions: PPUL is a diagnosis of exclusion. We define this entity as gestations where the site of pregnancy is never localized on TVS and serum hCG levels plateau on three or more occasions. In the worst-case scenario PPUL can represent ultrasonically missed EPs, but there is little place for laparoscopy or D&C. According to our data, MTX without surgical intervention is the preferred method of treatment.
