Video quality measurement in content-centric wireless networks

Video content is becoming major traffic in the wireless networks, and it is expected that the portion of video traffic will increase continuously. Because of the real-time nature of the video, providing the seamless service and fast delivery is very important. Content-Centric Networking (CCN) a new paradigm which is based on the content name and able to provide the requested content to the user in a fast and efficient manner compared to the traditional host-based networking approach. In this paper, the performance of a content-centric wireless network environment is analyzed by measuring the quality of video transmitted to the mobile terminal from the content server.
The Sharing Game: Benefits and Privacy Implications of (Co)-Location Sharing with Interdependences

Most popular location-based social networks, such as Facebook and Foursquare, let their users post location and co-location information (with other users). Such posts bring social benefits to the users who post them but also to their friends, who view them. Yet, they represent a severe threat to the users’ (location) privacy, as co-location information introduces interdependence between users. In this paper, we propose a game theoretical framework for analyzing and predicting the strategic behaviours of users of social networks regarding (co)-location information sharing. In addition, in order to design parametric utility functions as representative as possible of the users’ actual preferences, we conduct a survey targeted at Facebook users and rely on conjoint analysis for quantifying the users benefits of sharing vs. viewing (co)-location information and their preference for privacy vs. benefits.We evaluate our framework through data-driven numerical simulations. We show how users’ individual preferences influence each others’ decisions and identify several factors that significantly impact these decisions, specifically the considered adversary and the preference for privacy vs. benefits.
The new pyridoindole antioxidant SMe1EC2 and its intervention in hypoxia/hypoglycemia-induced impairment of longterm potentiation in rat hippocampus

The new pyridoindole antioxidant SMe1EC2 and its intervention in hypoxia/hypoglycemia-induced impairment of long-term potentiation in rat hippocampus Previously, the pyridoindole SMe1EC2 was proved to inhibit lipoperoxidation and carbonylation of proteins in rat brain cortex in the system Fe2+/ascorbate and improvement of resistance of the rat hippocampus was reported against ischemic conditions in vitro (hypoxia/hypoglycemia) expressed by the enhanced neuronal response recovery in reoxygenation. The hippocampus fulfils many of the criteria for a neuronal correlate of learning and memory. Recently, an impairment of hippocampal long-term potentiation (LTP) was reported under oxidative stress. Different therapies, including antioxidants, have been studied intensively concerning the impairment of neuronal plasticity. In this study marked reduction of LTP, elicited by a single burst (100 Hz, 1s) in the CA3-CA1 area of rat hippocampal slices, was shown due to transient hypoxia/hypoglycemia compared to control slices. On the basis of previously reported antioxidant and neuroprotective effects of SMe1EC2, its effect on loss of LTP in the hippocampus due to ischemic conditions was studied in vitro. The pyridoindole tested improved hypoxia/hypoglycemia-induced reduction of LTP compared to untreated hypoxic slices. An opposite effect of SMe1EC2 on LTP induction was found in control slices. The mechanism of SMe1EC2 action on LTP in ischemic conditions has been suggested to differ from the mechanism of its effect in "normoxia" and may be due to different redox status in control and ischemic brain tissue. The manifested LTP-protective effect of SMe1EC2 observed in the rat hippocampus exposed to ischemia in vitro may find exploitation in therapy associated with injured neuronal plasticity in some conditions, including ischemia, trauma and aging in man.
Almost all software testing is futile !

All software systems are subject to testing-for some of them testing is the major activity in the project. Testing, however, rarely gets the attention it deserves from researchers and developers, partly because its foundations are very weak and ill-understood. The principal purpose of testing is to detect (and then remove) faults in a software system. A number of techniques for carrying out testing, and in particular, for the generation of test sets exist. Many sophisticated (and expensive) tools are available on the market and many look to these to provide a solution to the problems of building fault-free systems. We consider the problem of fault detection and note that few, if any, of the existing methods really address the real issues. In particular no methods allow us to make any statement about the type or precise number of faults that remain undetected after testing is completed. Thus we cannot really measure the effectiveness of our testing activities in any rigorous way. However, by considering testing from a straightforward, theoretical point of view we demonstrate that a new method for generating test cases can provide a more convincing approach to the problem of detecting ALL faults and allows us to make sensible claims about the level and type of faults remaining after the testing process is complete .
Transient expression of DNA after ballistic introduction into Drosophila embryos.

Current procedures for introduction of DNA into Drosophila embryos require the time-consuming microinjection of DNA solution into individual embryos (1, 2). A procedure has recently been used successfully in plants, yeast and cultured cells for the ballistic introduction of DNA via tungsten (W) particles (3-5) . Using a modification of this procedure for Drosophila embryos, we have obtained transient expression at high efficiency. The technique also has the potential to be useful for germ line transformation. All incubations and procedures were at room temperature. DNA [a total of 1 —20 /ig of a 1 /*g//d solution in embryo injection buffer (0.1 mM sodium phosphate pH 6.8, 5 mM KC1)] was precipitated onto washed W particles (1.2 /*m diameter, obtained from Biolistics, Inc.) in a total volume of 65 p\, according to the recommendations of the manufacturer. After the DNA precipitation step, 50 /tl of supernatant was removed (without centrifugation). The tube containing the remaining pellet and residual supernatant (12 -15 /tl) was vortexed just before applying 8 /tl of this sample to the macroprojectile. Embryos (approximately 10—20,000), collected for 1 hr from a cage of w" flies onto yeasted apple juice agar plates, were dechorionated for 3 min with 50% bleach and spread out on a circle of wet Whatman # 1 filter paper. The filter was then blotted on paper towels, transferred to a fresh apple juice agar plate (10x1.5 cm) and the embryos on the filter bombarded with the DNA-carrying W particles, using a Biolistics bioparticle delivery system (DuPont) (3).
Socioeconomic status and lung cancer risk in Canada.

BACKGROUND Several epidemiological studies have found that lung cancer is inversely related to socioeconomic status (SES) and suggest it as a possible risk factor for lung cancer. This study examines SES and lung cancer risk in Canada. METHODS Mailed questionnaires with telephone follow-up were used to obtain data on 3280 newly diagnosed, histologically confirmed lung cancer cases and 5073 population controls, between 1994 and 1997, in eight Canadian provinces. Measurement included information on SES, smoking habits, alcohol use, diet, residential and occupational histories and both residential and occupational exposure to environmental tobacco smoke (ETS). Odds ratios (OR) and 95% CI were derived from unconditional logistic regression analysis. RESULTS Compared with high income adequacy, an increased risk was found among low income males and females, with adjusted OR of 1.7 (95% CI : 1.3-2.2) and 1.5 (95% CI : 1.1-2.0), respectively. Compared with < or = 8 years of education, the adjusted OR were 0.6 (95% CI : 0.5-0.7) and 0.6 (95% CI : 0.5-0.8) for > or = 14 years education among males and females, respectively. Lung cancer risk was significantly increased for males of some social classes. The population attributable risk for income adequacy, education and social class was 24%, 25% and 21% among males, respectively, and 14% and 19% for income adequacy and education among females, respectively, in this Canadian population. CONCLUSIONS A statistically significant association between income adequacy, education social class and lung cancer risk was found.
Towards a Semantics of Phish

Phishing constitutes more than half of all reported security incident son the Internet. The attacks cause users to erroneously trust websites and enter sensitive data because the email notifications and the website look familiar. Our hypothesis is that familiarity can be defined formally using history data from the user's computer, and effective presentation of the data can help users distinguishphishing messages from trustworthy messages.
Flying Carpets: the Production and Consumption of Tradition and Mystique

This paper examines the interplay between the local material culture and the global forces in the construction of an Aauthentic@ cultural product, in this case, the Turkish carpet. The preliminary results of an ethnographical study on the production, marketing, and consumption of handmade Turkish carpets (piled, knotted) and kilims (flat woven) are presented. We discuss how contemporary carpets trek the thin line between being authentic, aesthetic and cultural objects versus exotic souvenirs. A new wave of revivalism amidst a general decline in carpets indicates that authenticity is emergent. We discuss the issues of representation of the aesthetics of the Oriental AOther@ in the global relations. While the traditional has become modern, some modern Turkish carpets recreate authenticity. In this process, tradition and mystique of cultural products may come to be branded.

Scalable service deployment on software-defined networks

It is widely accepted that the network of the future will require a greater degree of service awareness and optimal use of network resources. This article presents an architectural design for an open software-defined network infrastructure that enables the composition of fast and guaranteed services in an efficient manner and the execution of these services in an adaptive way, taking into account better shared network resources provided by network virtualization. Validation results are provided with special emphasis on service deployment scalability over virtualized network infrastructures.
Neuron model interpretation of a cyclic motion control concept

Elastic properties of muscles and tendons are assumed to play a central role for the energy efficiency and robustness of locomotion in biological systems. Yet, the way in which the nervous system controls highly nonlinear body dynamics to produce stable periodic motions is far from being well understood. On the basis of a simple but very effective control law, which we developed and verified for variable impedance robots, we propose a controller model, which might be a very plausible hypothesis also for biological systems. The original robot controller has a bang-bang action triggered by the generalized force acting along a coordinate corresponding to the principal oscillation mode of the system. This coordinate is computed in a model-free, adaptive manner. It turns out that the control law can be easily realized with a neural network, whose weights are adapted according to the Hebbian learning rule. If this hypothesis is confirmed, cyclic body motions can be very easily and robustly implemented, with a surprisingly small number of neurons.
Thermodynamic Limits, Non-commutative Probability, and Quantum Entanglement

We construct a rigourous model of quantum measurement. A two-state model of a negative temperature amplifier, such as a laser, is taken to a classical thermodynamic limit. In the limit, it becomes a classical measurement apparatus obeying the stochastic axioms of quantum mechanics. Thus we derive the probabilities from a deterministic Schroedinger's equation by procedures analogous to those of classical statistical mechanics. This requires making precise the notion of `macroscopic. '
Local Ordinal Embedding

We study the problem of ordinal embedding: given a set of ordinal constraints of the form distance(i, j) < distance(k, l) for some quadruples (i, j, k, l) of indices, the goal is to construct a point configuration x1,. , xn in Rp that preserves these constraints as well as possible. Our first contribution is to suggest a simple new algorithm for this problem, Soft Ordinal Embedding. The key feature of the algorithm is that it recovers not only the ordinal constraints, but even the density structure of the underlying data set. As our second contribution we prove that in the large sample limit it is enough to know "local ordinal information" in order to perfectly reconstruct a given point configuration. This leads to our Local Ordinal Embedding algorithm, which can also be used for graph drawing.
Types for Delimited Control Operators

There are a great variety of control constructs in programming languages: conditionals, goto, coroutines, threads, processes, break, return, and, of course, continuations. The advantage of continuations over the others is that many of the other control constructs are expressible in terms of them. Unfortunately, the global continuations operators (e.g., call/cc) that are implemented in languages like Scheme and SML can be difficult to use. Delimited continuations are an alternative approach that provide better abstraction. However, designing a type system to accommodate them is nontrivial. Before looking at delimited continuations, let’s quickly review global continuations as exemplified by call/cc. The call/cc operator in Scheme and ML reifies the context of a program. That is, we take our evaluation contexts E and turn them into special values such as (cont E). A continuation value just installs the given context in place of the current one:

Lactoferrin Combined with Retinoic Acid Stimulates B1 Cells to Express IgA Isotype and Gut-homing Molecules

It is well established that TGF-β1 and retinoic acid (RA) cause IgA isotype switching in mice. We recently found that lactoferrin (LF) also has an activity of IgA isotype switching in spleen B cells. The present study explored the effect of LF on the Ig production by mouse peritoneal B cells. LF, like TGF-β1, substantially increased IgA production in peritoneal B1 cells but little in peritoneal B2 cells. In contrast, LF increased IgG2b production in peritoneal B2 cells much more strongly than in peritoneal B1 cells. LF in combination with RA further enhanced the IgA production and, interestingly, this enhancement was restricted to IgA isotype and B1 cells. Similarly, the combination of the two molecules also led to expression of gut homing molecules α4β7 and CCR9 on peritoneal B1 cells, but not on peritoneal B2 cells. Thus, these results indicate that LF and RA can contribute to gut IgA response through stimulating IgA isotype switching and expression of gut-homing molecules in peritoneal B1 cells.
Parameter properties of electronic and biological circuits and systems

The question what behaviors can be exhibited by a given electronic circuit upon variation of the parameters, is fundamental to electrical engineering. To efficiently adapt behavior according to need, say from stability to instability, or among stable or unstable periodicities, it is crucial to know how systems (generically and specifically) depend on parameters. Shrimps or swallow-tails are generic, characteristic parameter space regions that yield fixed stable periodic behavior. By dividing the parameter space into stable and unstable dynamical behavior, they provide such guidelines. In applications, shrimps have first been described at great details in the context of laser systems and electronic circuits, but it is still unknown whether they could also be found in realistic models of biophysics (and if so, whether biology exploits this as an alternative computing paradigm). Here, we provide first explicit examples of their existence.
A hybrid adaptive blind equalization for wireless communication

In this paper, a hybrid adaptive blind equalization method for wireless communication is proposed. For common blind equalizations, much attention has been paid on the additive noise (CMA, MCMA), and on the multipath environment.The method in this paper combines those algorithms and has a good performance. Compared with other algorithms, this method can be used in severe mutilpath environments for it has good decorrelation ability, at the same time makes full use of the characteristics of the communication signals, and in low SNR environment.
Policy Gradient for Coherent Risk Measures

Several authors have recently developed risk-sensitive policy gradient methods that augment the standard expected cost minimization problem with a measure of variability in cost. These studies have focused on specific risk-measures, such as the variance or conditional value at risk (CVaR). In this work, we extend the policy gradient method to the whole class of coherent risk measures, which is widely accepted in finance and operations research, among other fields. We consider both static and time-consistent dynamic risk measures. For static risk measures, our approach is in the spirit of policy gradient algorithms and combines a standard sampling approach with convex programming. For dynamic risk measures, our approach is actor-critic style and involves explicit approximation of value function. Most importantly, our contribution presents a unified approach to risk-sensitive reinforcement learning that generalizes and extends previous results.
On the Chiral Rings in N=2 and N=4 Superconformal Algebras

We study the chiral primary rings of N = 2 and N = 4 superconformal algebras (SCA) constructed over triple systems. The chiral primary states of N = 2 SCA’s realized over hermitian Jordan triple systems are given. Their coset spaces G/H are hermitian symmetric which can be compact or non-compact. In the non-compact case under the requirement of unitarity of the representations of G we ﬁnd an inﬁnite discrete set of chiral primary states associated with the holomorphic discrete series representations of G and their analytic continuation. Further requirement that the corresponding N = 2 module be unitary truncates this inﬁnite set to a ﬁnite subset. There are no chiral primary states associated with the other unitary representations of non-compact groups. Remarkably, the only non-compact groups G that admit holomorphic discrete series unitary representations are such that their quotients G/H with their maximal compact subgroups H are hermitian symmetric. The chiral primary states of N = 2 SCA’s constructed over the Freudenthal triple systems are also studied. These algebras have the special property that they admit an extension to N = 4 superconformal algebras with the gauge group SU (2) ⊗ SU (2) ⊗ U (1). We then generalize the concept of chiral rings to these maximal N = 4 superconformal algebras. We ﬁnd four dif-ferent rings associated with each sector (left or right moving). If one includes both sectors one gets 16 diﬀerent rings. We also show that our analysis yields all the possible rings of N = 4 SCA’s.
Prevalence of smoking, alcohol consumption and metabolic syndrome in patients with psoriasis*

Background Coexistence of obesity, hypertension, insulin resistance and dyslipidemia is defined as metabolic syndrome (MBS), which is among the important risk indicators for cardiovascular diseases, diabetes and stroke. Smoking and alcohol consumption are the other factors which lead to an increase in the risk of cardiovascular disease. Objective To investigate the prevalence of metabolic syndrome, smoking and alcohol consumption in psoriasis patients and the relationship between disease severity and these factors. Methods This cross-sectional study enrolled 563 patients with chronic plaque-type psoriasis, all of which completed a questionnaire and underwent a complete physical examination. Data about MBS components, psoriasis severity/duration, smoking and alcohol consumption, and cardiovascular diseases were recorded. Results A total of 563 patients with ages ranging from 18 to 78 years were evaluated. Metabolic syndrome was found in 12.6% of the patients [central obesity (38.7%), hypertension (14.3%), dyslipidemia (18.6%), diabetes (9.2%)], while 50.3% had smoking, and 3.3% had alcohol consumption. Patients with metabolic syndrome were older and more likely to have a longer disease duration than those without metabolic syndrome (p<0.05 for each). The prevalence of metabolic syndrome was higher in women than in men. Psoriasis was more severe in patients with central obesity, diabetes and smoking than in those without (p<0.05 for each). Study Limitations Retrospective design. Conclusions Our results indicate that MBS is a risk factor for psoriasis patients with advanced age. The relationship between disease severity and obesity, diabetes, and smoking in psoriasis patients indicates that the patients should be informed about the potential metabolic risks and receive therapies for behavioral changes besides anti-psoriatic treatment in order to minimize these risks.
Cloud computing for brain segmentation - a perspective from the technology and evaluations

This paper examines how cloud computing can be used in the area of brain segmentation with regard to satisfactory technical and user evaluations. It explains eleven APIs associated with each brain segment and the process of capturing data for each segment. Functionality and experiments associated with each API are discussed. Dancing is to capture data more easily. Results are used to explain why some segments are more active in dancing, with two evaluations undertaken. The first evaluation is the use of brain segmentations developed for medical cloud computing education (MCCE) and results confirm that cloud computing offers a 20% improvement in learning satisfaction. The second evaluation is focused on recapturing a lost skill. Results confirm that volunteers have their heartbeat, blood pressure, emotion, body coordination and vision at their peak. Benefits of using cloud brain segmentation technology are presented to illustrate positive impacts to healthcare informatics, education and cost reduction.
