Design and Implementation of Super-peer P2P Overlay Network Protocol and System for mobile IPTV

Recent researches of network structure are moving to high-level networks because there are already many research results of low-level network. Especially, current network services has been changed to the multimedia service using multicast routing such as IPTV(Internet Protocol Television) service. And then previous multicast services were provider oriented. So previous multicast structures were organized server/client model. But future multicast services will make user oriented services. Therefore there will be many service providers in the future. At this point, we study P2P network for supporting multi provider. So we research load balancing and contents lookup protocols in P2P network. In this paper, we propose network protocol and system based on super peer P2P for load balancing and efficiently service search. And we considered mobile environment for mobile IPTV.
Clinical manifestations of coxsackievirus infections in children.

Coxsackievirus B infection was proved by virus isolation or rise in virus titer in 26 children during 1972 at the Montreal Children's Hospital. Sixty-nine percent of these infections occurred during July and August. The spectrum of illness associated with the five implicated coxsackievirus B serotypes included gastroenteritis, pleurodynia, pharyngitis, meningitis, and pericarditis. Lower-respiratory tract infection, transverse myelitis, and an infectious mononucleosis-like syndrome were also seen, and coxsackievirus B1 was isolated from a lymphosarcoma. This experience emphasizes the need for appropriate viral studies in determining the cause of childhood illnesses suspected of being infectious in origin.
Crack Self-healing Behavior of Cementitious Composites Incorporating Various Mineral Admixtures

This study aims to develop and apply self-healing concrete as a new method for crack control and enhanced service life in concrete structure. This concept is one of the maintenance-free methods which, apart from saving direct costs for maintenance and repair, reduces the indirect costs - a saving generally welcomed by contractors. In this research, the self-healing phenomenon of autogenous healing concrete using geo-materials for practical industrial application was investigated. Moreover, a self-healing concrete was fabricated by ready-mixed car in a ready-mixed concrete factory, then used for the construction of artificial water-retaining structures and actual tunnel structures. The results show that the crack of concrete was significantly self-healed up to 28 days re-curing. Crack-width of 0.15mm was self-healed after re-curing for 3 days and the crack width decreased from 0.22 mm to 0.16 mm after re-curing for 7 days. Furthermore, it was almost completely self-healed at 33 days. It was founded that this phenomenon occurred mainly due to the swelling effect, expansion effect and re-crystallization. From these results, it is considered that the utilization of appropriate dosages of geo-materials has a high potential for one of new repairing methods of cracked concrete under the water leakage of underground civil infrastructure such as tunnels.
The Use of Vestibular Test Battery to Identify the Stages of Delayed Endolymphatic Hydrops

Objective Patients with delayed endolymphatic hydrops (DEH) underwent a vestibular test battery to evaluate the residual function, assess their clinical stage, and predict outcome. Study Design Case series with chart review. Setting University hospital. Subjects and Methods Twenty patients with DEH, 15 with ipsilateral type and 5 with contralateral type, were enrolled. All patients underwent audiometry and caloric, ocular vestibular-evoked myogenic potential (oVEMP), and cervical VEMP (cVEMP) tests. The DEH staging was based on vestibular test results. Stage 0 indicates that all 3 vestibular tests are normal, while stages I through III indicate abnormal results in tests 1 through 3, respectively. Results Of the 20 DEH patients, 2 patients were stage 0, 12 patients were stage I, 4 patients were stage II, and 2 patients were stage III. The median frequency of vertigo in patients with stages II and III was 4 episodes monthly, significantly less than 15 episodes monthly in those with stages 0 and I. Ipsilateral and contralateral types did not differ significantly in the stage distribution. The percentages of abnormal cVEMP, oVEMP, and caloric test results for patients with ipsilateral type were 80%, 33%, and 13%, not significantly different from those for contralateral type. Conclusions As a vertiginous attack may subside spontaneously for patients with long-term DEH, one must identify its clinical stage based on cVEMP, oVEMP, and caloric test results. In early stage DEH, most vestibular function remained relatively intact, leading to repeated vertiginous attacks. Conversely, subsidence of vertiginous episode can be anticipated in patients with late stage DEH.
Complexity of Locally Injective k-Colourings of Planar Graphs

A colouring of the vertices of a graph is called injective if every two distinct vertices connected by a path of length 2 receive different colours, and it is called locally injective if it is an injective proper colouring. We show that for k ≥ 4, deciding the existence of a locally injective k-colouring, and of an injective kcolouring, are NP -complete problems even when restricted to planar graphs. It is known that every planar graph of maximum degree ≤ 35k−52 allows a locally injective k-colouring. To compare the behaviour of planar and general graphs we show that for general graphs, deciding the existence of a locally injective k-colouring remains NP -complete for graphs of maximum degree 2 √ k (when k ≥ 7). 1. Definitions and Preliminaries All graphs in this note are simple undirected graphs without loops. We write NG(v) = {x | vx ∈ E(G)} (NG[v] = {v} ∪ NG(v)) to denote the open (closed, respectively) neighbourhood of a vertex v ∈ V (G) in a graph G, and more generally NG[A] = ⋃ v∈ANG[v] and NG(A) = NG[A] \A for a set A ⊆ V (G) of ∗Corresponding author.

Ethnicity and Other Possible Risk Factors for Candidemia at 3 Tertiary Care University Hospitals in Hawaii

A total of 108 cases of candidemia detected in 3 tertiary care university hospitals in Hawaii between January 2001 and December 2002 were retrospectively reviewed. Candida albicans, Candida glabrata, and Candida tropicalis accounted for 28% of the cases. Mortality among Filipino patients was significantly higher than that among other ethnic groups (71% vs 48%; P<.05).
Reduced feature based sentiment analysis on movie reviews using key terms

Word of mouth communication plays an influential role in propelling or sinking movies. Proper analysis of movie reviews published in social media helps in efficient decision making. Sentiment analysis aids in automating this time consuming task. Identifying the relevant data with the elimination of plot in movie reviews enhance the performance of any sentiment analysis algorithm. We propose an entity recognition method in the preprocessing stage to eliminate the irrelevant information from the reviews. Sets of N-grams are extracted from the document corpus as key terms. Extracted key terms together with an external lexicon are used to identify the sentiment conveying features in the review and these features are used to train the classifiers. Performance analysis is done on various classifiers and it is found that the proposed method outperforms existing approaches on movie reviews.
Collaborating through sounds : audio-only interaction with diagrams

The widening spectrum of interaction contexts and users’ needs continues to expose the limitations of the Graphical User Interface. But despite the benefits of sound in everyday activities and considerable progress in Auditory Display research, audio remains under-explored in HumanComputer Interaction (HCI). This thesis seeks to contribute to unveiling the potential of using audio in HCI by building on and extending current research on how we interact with and through the auditory modality. Its central premise is that audio, by itself, can effectively support collaborative interaction with diagrammatically represented information. Before exploring audio-only collaborative interaction, two preliminary questions are raised; first, how to translate a given diagram to an alternative form that can be accessed in audio; and second, how to support audio-only interaction with diagrams through the resulting form. An analysis of diagrams that emphasises their properties as external representations is used to address the first question. This analysis informs the design of a multiple perspective hierarchybased model that captures modality-independent features of a diagram when translating it into an audio accessible form. Two user studies then address the second question by examining the feasibility of the developed model to support the activities of inspecting, constructing and editing diagrams in audio. The developed model is then deployed in a collaborative lab-based context. A third study explores audio-only collaboration by examining pairs of participants who use audio as the sole means to communicate, access and edit shared diagrams. The channels through which audio is delivered to the workspace are controlled, and the effect on the dynamics of the collaborations is investigated. Results show that pairs of participants are able to collaboratively construct diagrams through sounds. Additionally, the presence or absence of audio in the workspace, and the way in which collaborators chose to work with audio were found to impact patterns of collaborative organisation, awareness of contribution to shared tasks and exchange of workspace awareness information. This work contributes to the areas of Auditory Display and HCI by providing empirically grounded evidence of how the auditory modality can be used to support individual and collaborative interaction with diagrams.

Conditional probability of long‐term survival in glioblastoma

Advances in glioblastoma care have resulted in a larger proportion of patients surviving beyond 2 years after diagnosis. It is not clear how long‐term survivors should be counseled with respect to future prognosis, or what factors influence that prognosis. The conditional probability of survival was evaluated from multiple time points in patients with glioblastoma, using Surveillance, Epidemiology, and End Results (SEER) data.

Enfin, grâce a l'outil du squelette, une reconstruction realiste du poisson est proposee.
Pediatric cardiac surgery in Northern Russia. Results from an international cooperative program

Abstract Objectives. In order to evaluate a Norwegian-Russian clinical cooperation, this study sought to compare the incidence, early mortality and morbidity of surgically treated patients with atrial septum defect (ASD), ventricular septum defect (VSD) and Tetralogy of Fallot (TOF) in Norway and Archangels region in Russia. Design. A retrospective analysis of patient records of all those surgically treated for ASD, VSD and TOF in Norway and from Archangels region from 1 January 2000 to 31 December 2005. Results. The Norwegian cohort consisted of 191 ASDs, 227 VSDs and 126 TOFs. The Russian cohort counted 128 ASDs, 77 VSDs and nine TOFs. Thirty-days mortality was 0.4% in the Norwegian VSD, 1.6% in the Norwegian TOF and 1.3% in the Russian VSD cohort. Postoperative complications in the Norwegian cohorts were 18.3% (ASDs), 15.9% (VSDs) and 34.1% (TOFs). The corresponding findings in Archangels were 4.7%, 11.7% and 0%. Conclusion. Surgery for ASDs, VSDs and TOFs can be carried out with minimal early mortality in both countries. The discrepancy in early postoperative morbidity illustrates the challenges in comparative studies between different countries, cultures and health care systems. The establishment of a decentralized surgical facility has increased the access to cardiac surgery to the population in Archangels region.
Cerebral circulation and the initiation mechanism of stroke in stroke-prone spontaneously hypertensive rats (SHRSP).

The predilection sites of cerebrovascular lesions (cerebral hemorrhage and/or softening) were studied in 1, 278 SHRSP. The precise supply to the main cerebral arteries was determined by trypan blue injections and microangiography. The three major territories were the anteromedial cortex, the occipital cortex, and the basal ganglia. A common angioarchitectural characteristic of these areas was the blood supply through"recurrent branchin"from the main stream. In the basal ganglia, where there is a preponderance of lesions, the arteries responsible for these lesions belonged to the lateral group of lenticulostriate arteries. The primary prestroke arterial lesions were further studied microangiographically in SHRSP killed at the time the initial symptoms of stroke were detected. These points were located at the"boundary zone"of the main cerebral arteries. Such findings indicated the importance of these two angioarchitectural minor loci as the basis for functional or organic circulatory disturbances that might cause stroke. Since these local factors for fufactors for stroke are common in the cortex and basal ganglia of rats and basal ganglia of humans, these SHRSP are regarded as good pathogenetic models for studies on stroke in humans. After simultaneous bilateral carotid ligation, accelerated induction of cerebrovascular lesons in young SHRSP and stroke-resistant SHR (SHRSR) showed predilection sites of stroke approximately consistent with those in SHRSP after natural death. (and rather consistent with those in humans). Such findings comfirmed that these lesions developed at the"minor loci"of cerebral circulation fed by"recurrent branches"from the main cerebral arteries. Regional cerebral blood flow (rCBF) was repeatedly measured by the hydrogen clearance method in both frontal and temporal cortices of SHRSP at the age of 50 days and thereafter. When SHRSP developed severe hypertension over 200 mmHg at the age of 60 days, rCBF in both frontal and temporal cortices began to decrease abruptly, especially in the frontal region of the cortex-one of the three pretension and at the hypertensive steady state, the frontal region constantly showed lower rCBF values than the temporal region. In contrast, such a reduction in rCBF was not noted in either SHRSR which developed moderate hypertension under 200 mmHg, or in Wistar-Kyoto rats (WK) with normal blood pressure under 150 mmHg.
Improvement of electrical and reliability properties of tantalum pentoxide by high-density plasma (HDP) annealing in N2O

This study aims to improve the electrical characteristics and reliability of low-pressure chemical vapor deposited (LPCVD) tantalum pentoxide (Ta/sub 2/O/sub 5/) films by a new post-deposition annealing technique using high-density plasma (HDP). Experimental results indicate that excited oxygen atoms generated by N/sub 2/O decomposition from HDP annealing can effectively reduce the carbon and hydrogen impurity concentrations and repair the oxygen vacancies in the as-deposited CVD Ta/sub 2/O/sub 5/ film, thereby resulting in a remarkable reduction of the film's leakage current. Two other post-deposition annealing conditions are compared: HDP O/sub 2/ annealing and conventional plasma O/sub 2/ annealing. The comparison reveals that HDP N/sub 2/O annealing has the lowest leakage current and superior time-dependent dielectric breakdown (TDDB) reliability.
Silicon microring resonators

An overview is presented of the current state‐of‐the‐art in silicon nanophotonic ring resonators. Basic theory of ring resonators is discussed, and applied to the peculiarities of submicron silicon photonic wire waveguides: the small dimensions and tight bend radii, sensitivity to perturbations and the boundary conditions of the fabrication processes. Theory is compared to quantitative measurements. Finally, several of the more promising applications of silicon ring resonators are discussed: filters and optical delay lines, label‐free biosensors, and active rings for efficient modulators and even light sources.
Static and dynamic actions of cytoplasmic Ca2+ in the adaptation of responses to saturating flashes in salamander rods.

1. In order to study the relative contribution to light adaptation of the various actions of Ca2+ in rod photoreceptors, changes in cytoplasmic calcium concentration ([Ca2+]i) were opposed by manipulating the calcium fluxes across the outer segment membrane at different times during the response to a bright flash. 2. When the outer segment was superfused with 0 Ca2+, 0 Mg2+,0 Na+ solution just before a bright flash, the period of response saturation was greatly prolonged. But if instead the solution change was made at progressively increasing times after the flash, the delay before the response recovered from saturation declined exponentially towards its value in Ringer solution with a time constant of around 1 s. In contrast, recovery time was little affected by stepping to 0 Ca+,0 Mg2+,0 Na+ solution before the flash and returning to Ringer solution shortly before the normal time of recovery from saturation. 3. When a bright flash was delivered just before the extinction of steady light, the response recovered from saturation progressively earlier as this steady intensity was increased. If, instead, the outer segment was transferred to 0 Ca2+,0 Mg2+,0 Na+ solution just before the bright flash then the time spent in saturation by the response was prolonged in darkness, but this additional delay progressively decreased as the steady intensity increased. 4. These results are consistent with the notion that the light‐induced reduction of the time spent in saturation by the bright flash response in Ringer solution resulted from the static decrease in [Ca2+]i induced by the background, while the additional delay in the recovery from saturation when further changes in [Ca2+]i were prevented stemmed from the abolition of the dynamic fall in [Ca2+]i during the flash response. 5. Analysis of the effects of steady light on the time spent in saturation by the bright flash response under these conditions suggests that actions of [Ca2+]i at, or soon after, the time of the flash are largely responsible for the graded changes which take place in the bright flash response during light adaptation, while rapid actions of [Ca2+]i at the time of response recovery also play a role in the adaptation of the steady response to background light itself. 6. These data have been interpreted in terms of differential actions of [Ca2+]i on ‘early’ stages (e.g. events leading to phosphodiesterase activation) and ‘late’ stages (e.g. guanylyl cyclase) in the transduction mechanism. A quantitative model is presented which suggests that actions of [Ca2+]i on ‘late’ stages play a proportinately larger role in background adaptation than actions on ‘early’ stages.
Correlation between persistent chlamydia pneumoniae infection and primary IgA nephropathy

To investigate the correlation between chlamydia pneumoniae (CP) infection and IgG nephropathy (IgAN). Seventy cases with primary IgAN were chosen along with 70 healthy blood donors and 12 cases which died of accidents, from which serum samples and kidney tissues obtained at autopsies were collected, respectively. CP IgG and CP IgA antibody titers in the serum were detected by using indirect immunofluorescence assay (IIF), and CP DNA in kidney tissues was detected using quantitative fluorescence PCR. The correlations of CP infection to positive CP DNA in kidney tissues, clinical manifestations of IgAN and pathological changes in kidney tissues were investigated. IgAN group had a significantly higher incidence of persistent CP infection than healthy blood donor group (P<0.01). No significant difference was found in the proportion of acute CP infection, previous infection and non-infection between different clinical subtypes of IgAN (P>0.05). The incidence of persistent CP infection in cases with severe proteinuria and persistent renal insufficiency was higher than in cases without severe proteinuria (P<0.05). Glomerular pathological injury scores and tubulointerstitial scores in cases with persistent CP infection were higher than those in cases without persistent CP infection (P<0.05). Renal pathological changes of cases with persistent CP infection were more severe than those of cases without persistent CP infection. Positive rate of CP DNA was higher among cases with severe proteinuria and persistent renal insufficiency than in cases without severe proteinuria (P=0.012). Glomerular pathological injury scores (P<0.05) and tubulointerstitial scores (P<0.01) in cases positive for CP DNA in kidney tissues were higher compared to negative cases; cases positive for CP DNA presented with more severe pathological changes than negative cases. Persistent CP infection was correlated with positive CP DNA in kidney tissues (P<0.01). The onset of IgAN was associated with persistent CP infection, but not significantly correlated with previous CP infection and acute CP infection.
A multi-flock approach to rapid dynamic generator coherency identification

In cases of intentional fault and cyber attack of smart grid systems, the reaction-time to mitigate disaster is small. Moreover, the large-scale impact of such disruptions is often in the form of inter-area oscillations. To address these issues, we propose a novel multi-flock-based technique to identify generator coherence within a short observation window suitable for mitigation approaches in smart grid systems. We present our approach and demonstrate its effectiveness in identifying generator clustering quickly for different fault scenarios of the 39-bus New England test system.

Mucosal vulval lichen planus: outcome, clinical and laboratory features

Background Mucosal lichen planus of the vulva is a rare but increasingly recognized condition. It has potentially severe complications such as fusion of the labia and vagina; the risk of developing squamous cell carcinoma (SCC) may be increased. An association between hepatitis B and C infection and skin or oral lichen planus appears to exist in certain geographical areas.
