Cloud enabled media streaming using Amazon Web Services

Streaming Media is a multimedia that is presented to an end user which is constantly received by while being delivered by a provider. Amazon Web Service (AWS) is a collection of remote computing services (also called web services) that together make up a Cloud computing platform, offered over the Internet by Amazon.com. The most central and well-known of these services are Amazon EC2 and Amazon S3. The service is much faster, scalable and cost effective than building a physical server farm. In the existing system, the media streaming is done in computers and it is not in use for common people. Therefore this system is proposed, to take media streaming to every user who uses smartphones. The main objective of this proposed system “Cloud Enabled Media streaming using Amazon Web Services” is streaming of media files through media server using the service of AWS. media server uses Amazon EC2 server for streaming and storing the multimedia files. The storage of multimedia files is done in EBS and Simple Storage Service(S3) maintains the backup of these files. This streaming of data through web servers of the cloud using mobile systems rather than third party software gives better control over the system in imparting new technologies to the end user. It introduces additional flexibility into the execution environments used by high-performance applications. This flexibility can be used to address important issues faced by applications such as traffic monitoring, online concerts, lectures, etc.
A potassium contribution to the response of the barnacle photoreceptor.

1. Intracellular recording from photoreceptors in the lateral eye of the barnacle show a brief negative‐going 'dip' shortly after the onset of the late receptor potential. This phase can sometimes result in a hyperpolarization relative to the resting membrane potential. 2. The dip is prominent in light‐adapted cells and is reduced by dark‐adaptation. Low extracellular Ca2+ also reduces it. 3. The amplitude of the dip changes inversely with the K+ concentration in the saline. 4. The amplitude of the dip depends on the membrane potential, with a reversal potential near ‐ 80 mV. 5. K+ blocking agents such as quinine and quinidine reduce or abolish the dip. 6. These observations indicate that the dip is due to a brief increase in K+ conductance which may be dependent on an influx of Ca ions. The fast decay of this phase may be brought about by a rapid uptake of Ca2+ by an intracellular mechanism.

Hepatic macrosteatosis: predicting appropriateness of liver donation by using MR imaging--correlation with histopathologic findings.

PURPOSE To retrospectively evaluate the diagnostic performance of magnetic resonance (MR) imaging in predicting the appropriateness of liver donation in potential living liver donors by using histopathologic results as the reference standard. MATERIALS AND METHODS This study was approved by institutional review board; all patients gave informed consent for the use of MR data for future research. Fifty-seven potential liver donors (40 male, 17 female; age range, 17-57 years; mean age, 32 years) underwent dual-echo 1.5-T MR imaging. Two radiologists qualitatively graded each MR image, with consensus for disagreements. Livers were assigned one of three degrees of hepatic steatosis on the basis of changes in hepatic signal intensity (SI) between in-phase and opposed-phase images. For quantitative analysis, a third radiologist calculated mean hepatic and mean splenic SI by averaging 25 hepatic regions of interest and three splenic regions of interest. Relative SI decrease (RSID) in the liver on opposed-phase images compared with in-phase images was calculated. Linear regression analysis was used to correlate RSID with the degree of total steatosis, macrosteatosis, and microsteatosis. Diagnostic performance for predicting the appropriateness of liver donation was analyzed. RESULTS Histologic findings of macrosteatosis resulted in 52 patients being categorized as appropriate donors, with the remaining five being categorized as inappropriate donors. RSID was correlated with total steatosis (r = 0.850). When the RSID criterion for inappropriateness of liver donation was set at 20%, the sensitivity, specificity, and accuracy were 100%, 92.3%, and 93%, respectively. When RSID was used, four livers that had been misclassified as inappropriate for transplantation were found to have microsteatosis of various degrees and a less than moderate degree of macrosteatosis at histologic analysis. Qualitative and quantitative analyses were comparably accurate. CONCLUSION When an RSID criterion of less than 20% was used, dual-echo MR imaging facilitated the correct prediction of appropriateness of liver donation in 53 of 57 patients.
Effects of Sharing Physiological States of Players in a Collaborative Virtual Reality Gameplay

Interfaces for collaborative tasks, such as multiplayer games can enable more effective and enjoyable collaboration. However, in these systems, the emotional states of the users are often not communicated properly due to their remoteness from one another. In this paper, we investigate the effects of showing emotional states of one collaborator to the other during an immersive Virtual Reality (VR) gameplay experience. We created two collaborative immersive VR games that display the real-time heart-rate of one player to the other. The two different games elicited different emotions, one joyous and the other scary. We tested the effects of visualizing heart-rate feedback in comparison with conditions where such a feedback was absent. The games had significant main effects on the overall emotional experience.
Sensitivity, specificity, and stability of CSF-tau in AD in a community-based patient sample.

OBJECTIVE To evaluate the sensitivity and specificity of CSF-tau in clinical practice as a diagnostic marker for AD compared with normal aging and depression, to study the stability of CSF-tau in longitudinal samples, and to determine whether CSF-tau levels are influenced by different covariates such as gender, age, duration or severity of disease, or possession of the APOE-epsilon4 allele. METHODS Consecutive AD patients from a community-based sample were studied, including 407 patients with AD (274 with probable AD and 133 with possible AD), 28 patients with depression, and 65 healthy elderly control subjects. A follow-up lumbar puncture was performed in 192 AD patients after approximately 1 year. CSF-tau was determined using a sandwich ELISA, which was run as a routine clinical neurochemical analysis. RESULTS CSF-tau was increased in probable (690+/-341 pg/mL; p < 0.0001) and possible (661+/-447 pg/mL; p < 0.0001) AD, but not in depression (231+/-110 pg/mL) compared with control subjects (227+/-101 pg/mL). Receiver operating characteristics analysis showed that a cutoff level of 302 pg/mL resulted in a sensitivity of 93% (95% CI, 90-96%) and a specificity of 86% (95% CI, 75-94%), with an area under the curve of 0.95 to discriminate AD from control subjects. Within the AD group, CSF-tau did not differ significantly between baseline and follow-up investigations, and was relatively stable between baseline and 1-year follow-up levels, with a coefficient of variation of 21.0%. High CSF-tau levels were also found in most AD patients with very short duration of dementia, and with Mini-Mental State Examination scores >23 (n = 205). In total, 193 of 205 patients (sensitivity, 94%) had a CSF-tau level higher than 302 pg/mL. CONCLUSIONS CSF-tau has a high sensitivity and specificity to differentiate AD from normal aging and depression, as demonstrated in a large community-based series of consecutive AD patients during which analyses were run continually in a clinical neurochemical laboratory. The increase in CSF-tau is found very early in the disease process in AD, is stable over time, and has a low interindividual variation on repeated sampling. Although high CSF-tau is found in some neurologic conditions (e.g., stroke), these findings suggest that CSF-tau may be of use to help in differentiating AD from normal aging and depression, especially early in the course of the disease, when the symptoms are vague and the diagnosis is especially difficult.
Automatic dialect classification for statistical machine translation

The training data for statistical machine translation are gathered from various sources representing a mixture of domains. In this work, we argue that when translating dialects representing varieties of the same language, a manually assigned data source is not a reliable indicator of the dialect. We resort to automatic dialect classification to refine the training corpora according to the different dialects and build improved dialect specific systems. A fairly standard classifier for Arabic developed within this work achieves state-of-the-art performance, with classification precision above 90%, making it usefully accurate for our application. The classification of the data is then used to distinguish between the different dialects, split the data accordingly, and utilize the new splits for several adaptation techniques. Performing translation experiments on a large scale dialectal Arabic to English translation task, our results show that the classifier generates better contrast between the dialects and achieves superior translation quality than using the original manual corpora splits.
Ciphertext Divided Anonymous HIBE and Its Transformation to Identity-Based Encryption with Keyword Search

: It has been shown that identity-based encryption with keyword search (IBEKS) can be constructed from level-2 anonymous hierarchical identity-based encryption (A-HIBE). A-HIBE is more complicated than non-anonymous HIBE (NA-HIBE). We have shown the deﬁnition of Ciphertext Divided A-HIBE (CD-A-HIBE). The basic idea of CD-A-HIBE is to make it possible to regard NA-HIBE as A-HIBE by dividing ciphertext into two parts so as not to leak the information of identity from the original ciphertext of NA-HIBE. We also have shown a concrete construction of CD-A-HIBE from BB1-HIBE, which is one of the NA-HIBE schemes and transformed BB1-CD-A-HIBE to IBEKS whose ciphertext is divided (CD-IBEKS). Then, the computational cost of CD-IBEKS is shown to be often more reasonable than that of IBEKS. In this paper, we show what type of NA-HIBE not limited to BB1-HIBE can be used for constructing CD-A-HIBE and how to transform a certain type of NA-HIBE to CD-A-HIBE generally. Then, we prove that these CD-A-HIBE schemes have indistinguishability and anonymity. The general transformation from CD-A-HIBE to CD-IBEKS is also shown. We prove that these CD-IBEKS schemes have indistinguishability.
Toxicity of Tritium Oxide to Mice

Summary The 30-day median lethal dose of H3 2 for CF No. 1 female mice is about 1 mc per g body weight when given in a single injection. The estimated radiation dosage is about 800 rep in the first 3 days and about 1000 rep in the first 12 days after injection. It is concluded that no unexpected factor of biological effectiveness exists for tritium β rays in relation to X or γ rays.
Implementing Guided Design in a Medical Instrumentation Course

I converted a medical instrumentation course to an experiential system called Guided Design. This is a teaching-learning system that is based on a set of open-ended problems. These establish the basis for both the student's study of subject matter, which is done outside of class, and decision-making work which is done in class. The classroom work is organized around printed "Instruction-Feedback" material which guides the students, who work in small groups of 4 to 7, in their decision-making efforts. Each instruction asks the students to make a decision about one step in the solution of an open-ended problem. The students agree on an answer before they compare their thinking with the ideas provided in the Feedback, which models the way an experienced decision-maker would have done the work. I include my experiences in taking Guided Design, which was developed at another institution, and transferring it to my situation. The characteristics of this transfer should be of interest to other developers of educational innovations, who desire to promote successful transfer.
Automatic inspection of solar panels based on Images stitching technique

Solar panels outer surface inspection is among the most challenging tasks which burden the solar plants supervisors. An automatic inspection based on image processing ensured by robots seems beneficial. In our approach, a robot equipped with an HD camera and a processing unit browses a set of solar panels (placed alongside). Afterward, the robot captures a series of successive images containing a set of targeted panels. Thereafter, the system generates a panoramic image of the panels which helps the said supervisors to check up the solar panels outer state i.e. (present of: dust, breaking, cracks,…) The proposed system is able to operate as an embedded system (ensured by Raspberry Pi card). It consists of two main stages: (1) images indexation and (2) Images stitching. As regards to the first stage, a series of solar panels images are captured successively and each of them is watermarked by a robust index, based on the convolutional encoding method and on the DCT blocks watermarking technique. Thereafter, the images undergo a brightness compensation as to obtain an accurate panoramic image. As for the second stage, the system starts by extracting the interest points (based on the SURF algorithm) of each captured image. Afterwards, the system implements a combination of Homography and RANSAC algorithm as to remove the mismatching points. And finally, each image undergoes a geometrical transformation according to the remaining matching points and subsequently the resulting images are stitched respectively as to obtain a panoramic image.
Growth in the neonatal period after repeat courses of antenatal corticosteroids: data from the ACTORDS randomised trial

Objective To determine the effect of repeated antenatal corticosteroids on postnatal changes in weight, linear growth and head circumference. Methods Mothers who entered the repeated dose of antenatal steroids (ACTORDS) trial were randomised to additional weekly steroid or placebo. Infant occipital-frontal head circumference, weight and crown-heel length were measured at birth and weekly for 4 weeks or until discharge, whichever was later. Lower leg length was measured using a knemometer daily for the first week, then thrice weekly. Results Of 145 babies studied (77.5% of the ACTORDS study infants from this centre), 70 were exposed to repeated antenatal steroids and 75 to placebo. There were no significant differences in prerandomisation demographic and pregnancy data. The mean gestational age at ACTORDS entry was 28.7 weeks and at birth was 31.4 weeks. The mean birth weight was 1618 g. There were no significant differences in postmenstrual age, weight, length or head circumference, nor in z-scores for these measurements, at birth, 4 weeks or discharge. In the first 2 weeks after birth, babies in both groups showed a decrease in z-scores for weight and length. After week 2, growth improved in both groups but babies exposed to repeat antenatal corticosteroids grew more rapidly, as measured by weight gain, increasing head circumference and increasing lower leg length knemometry. This rapid growth was most apparent around weeks 3–5 after birth. Conclusion Babies exposed to weekly doses of repeat antenatal corticosteroids demonstrate postnatal growth acceleration 3–5 weeks after birth.
Antigenic and Biochemical Characterization of the C-type Particle of the Stable Porcine Kidney Cell Line PK-15

The C-type particles observed by electron microscopy in PK-15 cells were demonstrated to have biochemical and biophysical properties associated with the oncornavirus group: density of 1:16 in a sucrose gradient, 70S RNA, and the RNA-dependent DNA polymerase. The group-specific interspecies antigen, gs-3, was not present. Evidence of a latent infection with a porcine parvovirus was also obtained.
Reliable safety message dissemination with minimum energy in VANETs

Road safety can be improved a lot with the help of Cooperative Collision Warning System, in which vehicles cooperate with each other for relaying safety messages to avoid accidents. Once a vehicle is in an abnormal status, which may lead to potential accidents, an emergency safety message will be generated and sent out to warn surrounding vehicles. In this paper, we address the routing problem of reliable dissemination of emergency safety messages in Vehicle Ad-Hoc Networks (VANETs). We aim to minimize the total transmission energy and reduce the transmission interference for delivering emergency safety messages to endangered vehicles while guaranteeing timeliness of safety messages and transmission reliability of inter-vehicle communications. The emergency safety message dissemination problem is formulated as a spanning tree optimization problem with both hop-count constraint and reliability-height constraint. A mixed integer programming model (MILP) is proposed for solving the studied problem optimally, which can be used as a benchmark for evaluating future fast heuristic algorithms. Simulations are conducted to validate our proposed MILP model.
Motivational Aspects of Deliberate Self-Poisoning in Adolescents

Summary A systematic study of 50 adolescent self-poisoners aged from 13 to 18 demonstrated considerable discrepancies between the reasons chosen by the subjects to explain the overdoses and those chosen by clinical assessors. Most adolescents indicated that they had been feeling lonely or unwanted, or angry with someone, and had taken the overdose to alleviate or demonstrate this distress. A third said they had wanted to die. In contrast, clinical assessors tended to attribute the overdose to punitive or manipulative reasons and suggested that only seven out of the 50 had wished to die. The adolescents rarely indicated that they had taken the overdose to get help; this may explain the resistance that may be shown to psychiatric intervention, and casts doubt on the possible effectiveness of preventive agencies. Modification of attitudes to both self-poisoning and early help-seeking may be a more effective means of prevention.
Data Management in Cloud Based Environment using k-Median Clustering Technique

Cloud Computing is the use of computing resources in a new and technologically more advanced manner. It is a fine blend of service oriented characteristics and utility based computing. The growth rate of data in cloud environment is reaching an exponential rate. Therefore there is a need to manage this huge heterogeneous data which can be both unstructured and structured in nature. This data can be managed at different levels in cloud i.e. at the end user level, cloud service provider level and data center level. The proposed approach defines how k medians clustering can be used as an efficient technique for management of data in cloud. The number of data centers is taken as the value of k in the proposed technique. This approach also takes into account the advantage of Cloud data base management system (CDBMS) and applies it to various distributed data centers.
CLINICAL CORRELATION OF NEONATAL AND MATERNAL HEMATOLOGICAL PARAMETERS AS PREDICTORS OF NEONATAL SEPSIS

36 ABSTRACT Objective: To evaluate the neonatal and maternal clinical manifestations and their hematological parameters, individually and in combination, as parameters which can be used to formulate a scoring system in determining neonatal sepsis. Design: A cross-sectional study conducted at the Neonatal Intensive Care Unit of a tertiary care teaching hospital. Methods: The study consisted of 100 neonates admitted at Neonatal Intensive Care Unit at the UP-PGH Medical Center who were clinically suspected of sepsis at birth and within 24 hours of life. A perinatal history, clinical profile, symptoms and laboratory data were recorded in each case. The neonatal hematological parameters included were total leukocyte count, total neutrophil count, lymphocytes, immature cells, immature to total leukocyte ratio, immature to mature cells ratio, nucleated red blood cells, lymphocytes, absolute neutrophil count, platelet count, and toxic granules. The maternal hematological parameters consisted of total leukocyte count, total neutrophil count, lymphocytes and platelet count. These parameters were evaluated based on the standard reference values. A blood culture was the standard indicator for proven sepsis. Results: There were 17 out of 100 neonates (17%) who had culture proven sepsis and they were predominantly preterm. Among the different parameters, the preterm infants, neonatal platelet count and maternal total leukocyte count were significantly associated with neonatal sepsis with p value of 0.047, 0.02, and 0.006 respectively. Based on these factors, a scoring system was devised to predict the probability of sepsis. A score of 3 had a 100% sensitivity and 91.3% specificity. Conclusion: A scoring system for predicting neonatal sepsis could be obtained by correlating the clinical manifestations of the neonate and the mother together with their hematological parameters.

Two Arabidopsis guard cell-preferential MAPK genes, MPK9 and MPK12, function in biotic stress response

Abscisic acid (ABA) plays a major role in plant development and adaptation to severe environmental conditions. ABA evokes cellular events to regulate stomatal apertures and thus contributes to the plant’s ability to respond to abiotic stresses. Reactive oxygen species (ROS) are produced in response to ABA and mediate ABA-induced stomatal closure. We have shown that two MAP kinases, MPK9 and MPK12, are highly and preferentially expressed in guard cells and function as positive regulators of ROS-mediated ABA signaling in guard cells. Cell biological and electrophysiological analyses demonstrated that MPK9 and MPK12 act downstream of ROS and cytosolic Ca2+ and upstream of anion channels in the guard cell ABA signaling cascade. Plant pathogens use stomata as the primary gateway to enter into their hosts, and previous studies have indicated crosstalk between ABA and defense signaling. Here we show that mpk9-1/12-1 double mutants are highly susceptible to Pseudomonas syringae DC3000 compared to WT plants. These results suggest that the regulation of stomatal apertures by MPK9 and MPK12 contributes to the first line of defense against pathogens.
