Seamless Support of Low Latency Mobile Applications with NFV-Enabled Mobile Edge-Cloud

Emerging mobile multimedia applications, such as augmented reality, have stringent latency requirements and high computational cost. To address this, mobile edge-cloud (MEC) has been proposed as an approach to bring resources closer to users. Recently, in contrast to conventional fixed cloud locations, the advent of network function virtualization (NFV) has, with some added cost due to the necessary decentralization, enhanced MEC with new flexibility in placing MEC services to any nodes capable of virtualizing their resources. In this work, we address the question on how to optimally place resources among NFV-enabled nodes to support mobile multimedia applications with low latency requirement and when to adapt the current resource placements to address workload changes. We first show that the placement optimization problem is NP-hard and propose an online dynamic resource allocation scheme that consists of an adaptive greedy heuristic algorithm and a detection mechanism to identify the time when the system will no longer be able to satisfy the applications' delay requirement. Our scheme takes into account the effect of current existing techniques (i.e., auto-scaling and load balancing). We design and implement a realistic NFV-enabled MEC simulated framework and show through extensive simulations that our proposal always manages to allocate sufficient resources on time to guarantee continuous satisfaction of the application latency requirements under changing workload while incurring up to 40% less cost in comparison to existing overprovisioning approaches.
Fetal growth restriction associated with measles virus infection during pregnancy

Abstract We report on a 28-week infant with growth restriction starting after 23 weeks' gestation because of measles virus (MV) infection of the mother. Histological findings for the placenta revealed extensive fibrin deposition and necrosis of the villi, and MV antigen was demonstrated in the syncytiotrophoblast by immunostaining. The MV-specific IgM level in the infant was negative, but that of the mother was positive. Therefore, we speculate that growth restriction is not attributed to direct infection with MV, but to placental dysfunction due to a decrease in intravillous blood flow and oxygen supply to the fetus.
Pandemic (H1N1) 2009 Vaccination and Class Suspensions after Outbreaks, Taipei City, Taiwan

In Taipei City, class suspensions were implemented beginning September 1, 2009 when transmission of pandemic (H1N1) 2009 infection was suspected. The uptake rate of pandemic (H1N1) 2009 vaccination (starting on November 16, 2009) among students 7–18 years of age was 74.7%. Outbreaks were mitigated after late November 2009.
Is persistence taught or caught?: two contrasting casestudies in the context of first year university teaching

This paper examines contrasting case studies involving two tutors of first year students enrolled in an undergraduate education program at an Australian University. Both tutors were given the same brief of designing a semester-long course that would foster the development of the habit of mind of persistence in their students. The two tutors went about it within different content areas and chose different approaches. Both worked within the principles of good practice to select their teaching strategies, but one explicitly taught her students about the habits of mind in general and persistence specifically, whereas the other did not mention it at all. Both sought to model the habit for their students, though the tutor who did not explicitly mention it to her class was more deliberate about the modeling. Given that the two courses were different it is not possible to compare student results to see if one approach worked better than the other. However, in both cases, the tutors felt that the students had demonstrated more persistence than previous groups they had taught. The tutors also commented that they had personally learned a lot from engaging with this specific focus and would seek to continue to incorporate it into their teaching and learning plans.
Use of Biological Motion based Cues and Ecological Sounds in the Neurorehabilitation of Apraxia

Technological progress in the area of informatics and human interface platforms create a window of opportunities for the neurorehablitation of patients with motor impairments. The CogWatch project (www.cogwatch.eu) aims to create an intelligent assistance system to improve motor planning and execution in patients with apraxia during their daily activities. Due to the brain damage caused by cardiovascular incident these patients suffer from impairments in the ability to use tools, and to sequence actions during daily tasks (such as making breakfast). Based on the common coding theory (Hommel et al., 2001) and mirror neuron primate research (Rizzolatti et al., 2001) we aim to explore use of cues, which incorporate aspects of biological motion from healthy adults performing everyday tasks requiring tool use and ecological sounds linked to the action goal. We hypothesize that patients with apraxia will benefit from supplementary sensory information relevant to the task, which will reinforce the selection of the appropriate motor plan. Findings from this study determine the type of sensory guidance in the CogWatch interface. Rationale for the experimental design is presented and the relevant literature is discussed.
INFLAMMATION AND INFLAMMATORY BOWEL DISEASE Alterations of the dominant faecal bacterial groups in patients with Crohn’s disease of the colon

Background and aim: The colonic microflora is involved in the pathogenesis of Crohn’s disease (CD) but less than 30% of the microflora can be cultured. We investigated potential differences in the faecal microflora between patients with colonic CD in remission (n=9), patients with active colonic CD (n=8), and healthy volunteers (n=16) using culture independent techniques. Methods: Quantitative dot blot hybridisation with six radiolabelled 16S ribosomal ribonucleic acid (rRNA) targeting oligonucleotide probes was used to measure the proportions of rRNA corresponding to each phylogenetic group. Temporal temperature gradient gel electrophoresis (TTGE) of 16S rDNA was used to evaluate dominant species diversity. Results: Enterobacteria were significantly increased in active and quiescent CD. Probe additivity was significantly lower in patients (65 (11)% and 69 (6)% in active CD and quiescent CD) than in healthy controls (99 (7)%). TTGE profiles varied markedly between active and quiescent CD but were stable in healthy conditions. Conclusion: The biodiversity of the microflora remains high in patients with CD. Enterobacteria were observed significantly more frequently in CD than in health, and more than 30% of the dominant flora belonged to yet undefined phylogenetic groups.
Teaching Recruits’ Physical Education Backgrounds and Beliefs about Purposes for Their Subject Matter

This study described 476 recruits’ physical education backgrounds and beliefs about the purposes for physical education. Beliefs about purposes are formed in part by physical education experiences and are important to examine because they are difficult to change and because they influence students’ receptivity to teacher education. Most recruits recalled programs that focused on traditional team sports, games, and fitness programs, with less emphasis on individual sports and expressive or noncompetitive activities. Few differences by sex, race, or socioeconomic status were found. Recruits’ reported purposes were coded into nine categories; the top purposes were learning skills, named specific activities, and fitness. The discussion focuses on the possibility of the existence of a de facto national curriculum and factors to consider if changes in physical education curriculum are desired.
The baboon syndrome: systemically‐induced allergic contact dermatitis
 *

The catchword “baboon syndrome” is used to denote a characteristic distribution pattern of systemic allergic contact dermatitis. Diffuse erythema of the buttocks, upper inner surface of the thighs, and axillae are characteristic features. We describe 3 cases provoked by ampicillin, nickel and mercury. The condition may be overlooked and suspected of being a textile dermatitis or seborrhoeie dermatitis of the elderly.
Neural Regulation of Cardiovascular Response to Exercise: Role of Central Command and Peripheral Afferents

During dynamic exercise, mechanisms controlling the cardiovascular apparatus operate to provide adequate oxygen to fulfill metabolic demand of exercising muscles and to guarantee metabolic end-products washout. Moreover, arterial blood pressure is regulated to maintain adequate perfusion of the vital organs without excessive pressure variations. The autonomic nervous system adjustments are characterized by a parasympathetic withdrawal and a sympathetic activation. In this review, we briefly summarize neural reflexes operating during dynamic exercise. The main focus of the present review will be on the central command, the arterial baroreflex and chemoreflex, and the exercise pressure reflex. The regulation and integration of these reflexes operating during dynamic exercise and their possible role in the pathophysiology of some cardiovascular diseases are also discussed.
On the Feasibility of Overshadow Enlargement Attack on IEEE 802.15.4a Distance Bounding

Distance-bounding protocols are able to measure a secure upper bound to the distance between two devices. They are designed to resist to reduction attacks, whose objective is reducing the measured distance. In this paper we focus on the opposite problem, the enlargement attack, which is aimed at enlarging the measured distance. We analyze the feasibility of enlargement attacks through overshadow strategies on 802.15. 4a UWB distance-bounding protocols. We show that the overshadow strategies, generally considered feasible by the existing literature, are actually difficult to carry out. Depending on the delay introduced by the adversary, there are cases in which they have no effect or their effect is not controllable.
Network Analysis of Third Party Tracking: User Exposure to Tracking Cookies through Search

Internet advertisers reach millions of customers through practices that real time tracking of users' online activities. The tracking is conducted by third party ad services engaged by the Web sites to facilitate marketing campaigns. Previous research has investigated tracking practices and tracking agencies associated with popular Web sites. Here we investigate the network properties of the third party referral structures that facilitate gathering of user information for the delivery of personalized ads. By considering third party domains associated with the top ten search results for a diverse set of queries, we arrived at the networks of third party domains in four search markets. We show a consistent network structure across markets, with a dominant connected component that, on average, includes 92.8% of network vertices and 99.8% of the connecting edges. There is 99.5% chance that a user will become tracked by all top 10 trackers within 30 clicks on search results. Finally, the third party networks exhibit properties of the small world networks. This implies a high-level global and local efficiency in spreading the user information and delivering targeted ads.
[Early effects of systemic and intravitreal bevacizumab (avastin) therapy for neovascular age-related macular degeneration].

PURPOSE The purpose of this study was to evaluate the early treatment response following systemic and intravitreal bevacizumab therapy in patients with neovascular age-related macular degeneration (AMD). PATIENTS AND METHODS In a prospective cohort study 12 eyes with neovascular AMD were treated with 5 mg/kg systemic bevacizumab, and 13 eyes with 1 mg intravitreal bevacizumab. Systemic therapy was given three times at 2-week intervals, intravitreal therapy up to three times at 4-week intervals. Patients were evaluated according to best corrected visual acuity (VA) and optical coherence tomography (OCT) at baseline as well as at week 1, week 4 and week 12 after therapy. Fluorescein angiography (FA) was performed at baseline and week 12. RESULTS Systemic and intravitreal bevacizumab therapy showed a treatment response within one week. Visual acuity improved at week 1 by 4.9 letters from baseline in the systemic and by 6.9 letters in the intravitreal treatment group. Central retinal thickness (CRT), as measured by OCT decreased by 51.9 microm and 176.4 microm, respectively. At month 3 a persistent treatment effect was detectable. Mean gain in visual acuity was 11 letters in the systemic and 8.3 letters in the intravitreal group, CRT had decreased by 100 microm and 153.8 microm, respectively. Leakage as evaluated by FA was significantly reduced or absent in all patients. CONCLUSION The early treatment responses following systemic and intravitreal bevacizumab appear to be similar. Both groups show improvement in VA and decrease in CRT within 1 week and up to 3 months. Long-term follow-up is required to evaluate the safety and treatment durability of both treatment modalities using bevacizumab.
Emergence of Spatio-Temporal Patterns in Neuronal Activity

Abstract Neuronal Activity, Emergence of Spatio-Temporal Patterns This paper explores if dynamic modulation of coherent firing serves cortical functions. We recorded neuronal activity in the frontal cortex of behaving monkeys and found that tempo ral coincidences of spikes firing of different neurons can emerge within a fraction of a second in relation to the animal behavior. The temporal patterns of the correlation could not be predicted from the modulations of the neurons firing rate and finally, the patterns of correla tion depend on the distance between neurons. These findings call for a revision of prevailing models of neural coding that solely rely on firing rates. The findings suggest that modification of neuronal interactions can serve as a mechanism by which neurons associate rapidly into a functional group in order to perform a specific computational task. Increased correlation between members of the groups, and decreased or negative correlation with others, enhance the ability to dissociate one group from concurrently activated competing groups. Such modu lation of neuronal interactions allows each neuron to become a member of several different groups and participate in different computational tasks.

Phosphorylation of Caveolin by Src Tyrosine Kinases

Caveolae are flask-shaped plasma membrane specializations that are thought to exist in most cell types. A 22-kDa protein, caveolin, is an integral membrane component of caveolae membranes in vivo. Previous studies have demonstrated that caveolin is phosphorylated on tyrosine by oncogenic viral Src (v-Src) and that caveolin is physically associated as a hetero-oligomeric complex with normal cellular Src (c-Src) and other Src family tyrosine kinases. Caveolin contains eight conserved tyrosine residues that may serve as potential substrates for Src. Here, we have begun to study the phosphorylation of caveolin by Src family tyrosine kinases both in vitro and in vivo. Using purified recombinant components, we first reconstituted the phosphorylation of caveolin by Src kinase in vitro. Microsequencing of Src-phosphorylated caveolin revealed that phosphorylation occurs within the extreme N-terminal region of full-length caveolin between residues 6 and 26. This region contains three tyrosine residues at positions 6, 14, and 25. Deletion mutagenesis demonstrates that caveolin residues 1-21 are sufficient to support this phosphorylation event, implicating tyrosine 6 and/or 14. In vitro phosphorylation of caveolin-derived synthetic peptides and site-directed mutagenesis directly show that tyrosine 14 is the principal substrate for Src kinase. In support of these observations, tyrosine 14 is the only tyrosine residue within caveolin that bears any resemblance to the known recognition motifs for Src family tyrosine kinases. In order to confirm or refute the relevance of these in vitro studies, we next analyzed the tyrosine phosphorylation of endogenous caveolin in v-Src transformed NIH 3T3 cells. In vivo, two isoforms of caveolin are known to exist: α-caveolin contains residues 1-178 and β-caveolin contains residues 32-178. Only α-caveolin underwent tyrosine phosphorylation in v-Src transformed NIH 3T3 cells, although β-caveolin is well expressed in these cells. As β-caveolin lacks residues 1-31 (and therefore tyrosine 14), these in vivo studies directly demonstrate the validity of our in vitro studies. Because α- and β-caveolin are known to assume a distinct but overlapping subcellular distribution within a single cell, v-Src phosphorylation of α-caveolin may only affect a subpopulation of caveolae that contain α-caveolin.
Depressive type and state effects on personality measures

We examine the hypothesis that the effect of mood state on personality questionnaire scores is more a function of diagnosis than of depression severity. Sixteen endogenous and 83 neurotic depressives completed a battery of personality questionnaires at a baseline assessment and again 20 weeks later. Scores on the personality measures changed significantly. Endogenous depressives were found to have more pronounced changes on measures of dependence and timidity, but when change in mood state was partialled out only one of the dependence measures and timidity remained significant. Thus the hypothesis only received partial support ‐ change in mood state appears to be the major factor in elevating personality questionnaire scores.
Cross-protection among serotypes of group A streptococci.

Cross-protection between two serotypes of Group A streptococci was demonstrated. Type 55 strain 2004 and type 60 strain 365 shared a cross-protective relationship in one direction: type 55 antiserum possessed opsonophagocytic activity against type 60, but type 60 antiserum was inactive against type 55. Agar-gel diffusion tests with both types, their antisera, and reciprocally absorbed sera showed that type 55 possesses two M antigens; one of them is identical to that of type 60 and is responsible for the cross-protection. This cross-protection was found in sera of patients during an outbreak of acute glomerulonephritis caused by type 55. Fifty percent of the patients who developed immunity against the infecting type 55 also developed immunity against type 60 as tested by opsonophagocytic or bactericidal tests. None of the sera tested possessed a significant amount of opsonophagocytic activity against control types of group A streptococci.
Trinucleotide repeat polymorphism in the androgen receptor gene (AR).

Source/Description: The human androgen receptor gene contains in exon one a (CAG)N(CAA) repeat, encoding a polyglutamine stretch, at position 172 following the translation start codon (1). This polymorphism is extremely useful for diagnosis in families with the Androgen Insensitivity Syndromes, which display a high incidence of distinctive mutations in the androgen receptor gene (2-5). The polymorphism could be typed using the polymerase chain reaction (PCR). The length of the repeat in allele BlO was (CAG)19(CAA). Frequency: Eleven different allele products were detected among 63 chromosomes of22 female and 19 male, unrelated Caucasians. The heterozygosity in females is 0.89. The androgen been
The application of E-commerce in Business Application: Their Problems and Prospects

The paper outlines the reality of global e-commerce, pointing out inherent risk areas that could threaten the system. This paper investigates the relationship between globalization, ecommerce adoption or acceptance that lead to business performance and effectiveness. In this paper, we will discuss how globalization impact on ecommerce in business with policy implementation, pro and cons of e-commerce enhancement in the increase to business. It will outline the framework of the new policies and regulations needed by e-commerce. There will be future research and conclusion based on what we believe globalization of e-commerce will lead to growth in business. The World Wide Web has become an environment for distributed applications of all kinds. The originally intended use of the Web as distributed system for knowledge-interchange seems to disappear, compared to the increasing number of Electronic Commerce Web applications. Organizations offer products and services in the Web, and use the Web as a means to integrate their heterogeneous business application systems. Offering Web-based products requires combining services of different application systems, which were build on the coarse-grained Web implementation model. Reusing the respective fine-grained services and application systems respectively integrating these cross-platform application systems increases quality and reduces costs of the new product. The Web as a global point of sale seems to be very promising but obviously suffers from its heritage the coarse-grained implementation model. E-Commerce, an electronic medium that generates revenue on demand, can be demanding in maintaining security administration and management. Ensuring a desktop PC, or a server on the LAN can provide moderate challenges in securing the device, securing a device in an E-Commerce environment can prove most challenging. Whether Consumer or Business, ECommerce provides extraordinary challenges in that our organization uses this revenue generating medium to provide a service which is highly accessible publicly and privately and usually requires undesirable communication to be opened to these devices. The criticality of E-Data poses additional security measures, sensitive data pertaining to customers and business partners traversing private to public networks requires proactive measures to insure a secure environment. In the problem area, we will describe some attacks in business applications by unauthorized access of business software and their related protocols and in the prospect area, we will conclude some detection methods for the attacks and their prospective prevention methods.
Wireless MIMO switching with zero-forcing relaying

A wireless relay with multiple antennas is called a multiple-input-multiple-output (MIMO) switch if it forms a one-to-one mapping from the inputs (uplinks) to the outputs (downlinks). This paper studies the case with N source stations and N destination stations (which may be the same set), so that the mapping is any permutation of the N inputs. Moreover, the switching is achieved by “precode-and-forward”, i.e., the relay precodes the received vector signal by a zero-forcing matrix and transmits it, so that each destination station receives only its desired signal with enhanced noise but no interference. Assuming full channel state information is available at the switch, the design of the zero-forcing precoder for maximizing some performance metric based on the received signal-to-noise ratios is investigated. The problem with two stations is completely solved in closed form in certain cases. In other cases, heuristic algorithms are proposed to optimize the precoder. These algorithms are shown to be near-optimal.
