Special Issue of Ieee Transactions on Multimedia:cloud-based Mobile Media: Infrastructure, Services and Applications1 Attribute-based Access to Scalable Media in Cloud-assisted Content Sharing Networks 2 Index Terms

4 This paper presents a novel Multi-message Ciphertext Policy Attribute-Based Encryption (MCP-ABE) technique, 5 and employs the MCP-ABE to design an access control scheme for sharing scalable media based on data consumers' 6 attributes (e.g., age, nationality, gender) rather than an explicit list of the consumers' names. The scheme is efficient 7 and flexible because MCP-ABE allows a content provider to specify an access policy and encrypt multiple messages 8 within one ciphertext such that only the users whose attributes satisfy the access policy can decrypt the ciphertext. 9 Moreover, the paper shows how to support resource-limited mobile devices by offloading computational intensive 10 operations to cloud servers while without compromising data privacy. 12 Access control, data security and privacy, scalable media content, cloud computing.
Relative importance of different components of speech contributing to perception of emotion

The objective of this study is to understand the relative importance of different components of speech that contribute to perception of emotion in speech. The four components considered in this study relate to the vocal tract system, excitation source and suprasegmental (pitch and duration) information. For this study, data collected from an artist, producing speech with different emotions is used. A flexible analysis-synthesis tool is used to modify the parameters of speech in a desired manner. Results of subjective studies show that all the four components are important in perceiving emotion in an utterance in comparison to the corresponding neutral utterance. Individually, the pitch contour seems to be the dominant component, and the duration seems to play less a significant role. It is also interesting to note that the importance of these components vary in perception for different types of emotions.
Low-Rank Tensor Completion with Spatio-Temporal Consistency

Video completion is a computer vision technique to recover the missing values in video sequences by filling the unknown regions with the known information. In recent research, tensor completion, a generalization of matrix completion for higher order data, emerges as a new solution to estimate the missing information in video with the assumption that the video frames are homogenous and correlated. However, each video clip often stores the heterogeneous episodes and the correlations among all video frames are not high. Thus, the regular tenor completion methods are not suitable to recover the video missing values in practical applications. To solve this problem, we propose a novel spatially-temporally consistent tensor completion method for recovering the video missing data. Instead of minimizing the average of the trace norms of all matrices unfolded along each mode of a tensor data, we introduce a new smoothness regularization along video time direction to utilize the temporal information between consecutive video frames. Meanwhile, we also minimize the trace norm of each individual video frame to employ the spatial correlations among pixels. Different to previous tensor completion approaches, our new method can keep the spatio-temporal consistency in video and do not assume the global correlation in video frames. Thus, the proposed method can be applied to the general and practical video completion applications. Our method shows promising results in all evaluations on both 3D biomedical image sequence and video benchmark data sets.
A Lie Algebraic Approach for Consistent Pose Registration for General Euclidean Motion

We study the problem of registering local relative pose estimates to produce a global consistent trajectory of a moving robot. Traditionally, this problem has been studied with a flat world assumption wherein the robot motion has only three degrees of freedom. In this paper, we generalize this for the full six-degrees-of-freedom Euclidean motion. Given relative pose estimates and their covariances, our formulation uses the underlying Lie algebra of the Euclidean motion to compute the absolute poses. Ours is an iterative algorithm that minimizes the sum of Mahalanobis distances by linearizing around the current estimate at each iteration. Our algorithm is fast, does not depend on a good initialization, and can be applied to large sequences in complex outdoor terrains. It can also be applied to fuse uncertain pose information from different available sources including GPS, LADAR, wheel encoders and vision sensing to obtain more accurate odometry. Experimental results using both simulated and real data support our claim
How outcomes are achieved through patient portals: a realist review

OBJECTIVE To examine how patient portals contribute to health service delivery and patient outcomes. The specific aims were to examine how outcomes are produced, and how variations in outcomes can be explained. METHODS We used a realist review method, which aims to describe how 'an intervention works, for whom, and in what circumstances' by analyzing patterns between context, mechanism, and outcomes. We reviewed 32 evaluation studies of patient portals published since 2003. RESULTS The reviewed evaluations indicate that as a complement to existing health services, patient portals can lead to improvements in clinical outcomes, patient behavior, and experiences. Four different mechanisms are reported to yield the reported outcome improvements. These are patient insight into personal health information, activation of information, interpersonal continuity of care, and service convenience. The vast majority of evaluations were conducted in integrated health service networks in the USA, and we detected no substantial variation in outcomes across these networks. DISCUSSION AND CONCLUSIONS Patient portals may impact clinical outcomes and health service delivery through multiple mechanisms. Given the relative uniformity of evaluation contexts, we were not able to detect patterns in how patient portals work in different contexts. Nonetheless, it appears from the overwhelming proportion of patient portal evaluations coming from integrated health service networks, that these networks provide more fertile contexts for patient portals to be effective. To improve the understanding of how patient portals work, future evaluations of patient portals should capture information about mechanisms and context that influence their outcomes.
Considering the Specific Impact of Harsh Conditions and Oil Weathering on Diversity, Adaptation, and Activity of Hydrocarbon-Degrading Bacteria in Strategies of Bioremediation of Harsh Oily-Polluted Soils

Weathering processes change properties and composition of spilled oil, representing the main reason of failure of bioaugmentation strategies. Our purpose was to investigate the metabolic adaptation of hydrocarbon-degrading bacteria at harsh conditions to be considered to overcome the limitations of bioaugmentation strategies at harsh conditions. Polluted soils, exposed for prolonged periods to weathered oil in harsh soils and weather conditions, were used. Two types of enrichment cultures were employed using 5% and 10% oil or diesel as sole carbon sources with varying the mineral nitrogen sources and C/N ratios. The most effective isolates were obtained based on growth, tolerance to toxicity, and removal efficiency of diesel hydrocarbons. Activities of the newly isolated bacteria, in relation to the microenvironment from where they were isoalted and their interaction with the weathered oil, showed individual specific ability to adapt when exposed to such factors, to acquire metabolic potentialities. Among 39 isolates, ten identified ones by 16S rDNA genes similarities, including special two Pseudomonas isolates and one Citrobacter isolate, showed particularity of shifting hydrocarbon-degrading ability from short chain n-alkanes (n-C12–n-C16) to longer chain n-alkanes (n-C21–n-C25) and vice versa by alternating nitrogen source compositions and C/N ratios. This is shown for the first time.
Phototransistors based on InP HEMTs and their applications to millimeter-wave radio-on-fiber systems

Phototransistors based on InP high electron-mobility transistors (HEMTs) are investigated for millimeter-wave radio-on-fiber system applications. By clarifying the photodetection mechanism in InP HEMTs, the phototransistor internal gain is determined. We present their use as millimeter-wave harmonic optoelectronic mixers and characterize them at the 60-GHz band. In order to evaluate the InP HEMT optoelectronic mixer performance, internal conversion gain is introduced and a maximum of 17 dB is obtained for 60-GHz harmonic optoelectronic up-conversion. Utilizing them, we construct a 60-GHz radio-on-fiber system and demonstrate 622-Mb/s data transmission over 30-km single-mode fiber and 3-m free space at 60-GHz band.
Direct and Reverse Hofmeister Effects on Interfacial Water Structure

The adsorption of Hofmeister anions to negatively charged hydrophilic, negatively charged hydrophobic, and positively charged hydrophilic aqueous/oxide interfaces was studied by analyzing changes in the adjacent interfacial water structure using vibrational sum frequency spectroscopy (VSFS). At the negatively charged quartz/water interface at pH 10.0, it was found that the introduction of sodium salts of weakly hydrated monovalent anions (i.e., SCN– and ClO4–) led to less attenuation of the water structure than when NaCl was added to solution. Addition of NaBr and NaNO3 gave rise to intermediate behavior. These results are consistent with less exclusion of the more weakly hydrated anions from the quartz substrate and the counterion double layer. As such, the monovalent anions followed a direct Hofmeister series. When the quartz surface was modified with an octadecyltrichlorosilane (OTS) monolayer, the ordering of the anions remained the same. Again, this is consistent with preferential exclusion of Cl– ov.
How leader and follower attachment styles are mediated by trust

The current study utilizes attachment theory to understand how leader–follower relationships impact emotional and behavioral outcomes in the workplace. Specifically, we examine the roles of two dysfunctional attachment styles – anxious and avoidant attachment – as determinants of trust in leaders, stress and citizenship behaviors. Results showed that followers with anxious attachment orientations reported experiencing more stress, whereas followers with avoidant attachment orientations were less likely to engage in organizational citizenship behaviors. Moreover, we found that the relationship between attachment orientations and workplace outcomes are mediated by affective and cognitive trust. However, these negative outcomes only occur when the follower has a leader with an avoidant attachment orientation. Implications for training, selection, job design and understanding leader–follower dynamics are discussed.
Appropriation strategies and open innovation in SMEs

Drawing upon data from the fifth UK Innovation Survey, this article sheds light on how management choices on the nature of appropriation relate to management choices on the degree of openness within small and medium-sized enterprises (SMEs). To this end, our findings indicate a threshold effect of both informal and formal appropriation mechanisms on the likelihood of engaging in both coupled and inbound open innovation. That is, an emphasis on appropriation appears to be important in shifting firms from a closed to an open strategy. There is, however, little evidence that either approach to appropriation increases the extent of open innovation. In this, only informal intellectual property (IP) protection mechanisms associate with an increasing extent of inbound open innovation.
Receptor Blockade: A Novel Approach to Protect the Brain From Pneumococcal Invasion

Background Pneumococci are the major cause of bacterial meningitis globally. To cause meningitis pneumococci interact with the 2 endothelial receptors, polymeric immunoglobulin receptor (pIgR) and platelet endothelial cell adhesion molecule (PECAM-1), to penetrate the blood-brain barrier (BBB) and invade the brain. Methods C57BL/6 mice were infected intravenously with bioluminescent pneumococci, and treated with ceftriaxone (1 hour postinfection) and anti-pIgR and PECAM-1 antibodies (1 or 5 hours postinfection), then monitored for 5 and 10 days. Bacterial brain invasion was analyzed using IVIS imaging and bacterial counts. Results Ceftriaxone, given early after pneumococcal challenge, cleared pneumococci from the blood but not from the brain. After combining ceftriaxone with receptor blockade, using anti-pIgR and PECAM-1 antibodies, we found 100% survival after 5 and 10 days of infection, in contrast to 60% for ceftriaxone alone. Combined antibiotic and antibody treatment resulted in no or few viable bacteria in the brain and no microglia activation. Antibodies remained bound to the receptors during the study period. Receptor blockade did not interfere with antibiotic permeability through the BBB. Conclusions We suggest that adjunct treatment with pIgR and PECAM-1 antibodies to antibiotics may prevent pneumococcal meningitis development and associated brain damages. However, further evaluations are required.
Recommender system improvement cases through implicit feedbacks from social network

Recommender systems (RS) performance largely depends on diverse types of input that characterize users' preference in the form of both explicit and implicit feedbacks. An explicit feedback is stated directly by an explicit input from users regarding their interest in some options of services or products. Such feedback, however, is not always available. On the other hand, an implicit feedback, which reflects users' opinion indirectly through user behavior is far more abundant. In this paper, we elaborate several ways to improve the RS of three real cases dataset (online travel service, online transportation, and telecommunication service provider) through implicit feedbacks. In the first case, we analyze the effect of a simple feedback from users' input during registration without using any social network analysis (SNA). In the second case, we analyze the effect of community structure extracted from its SNA as its additional attributes. In the third case, we analyze the effect of more additional feedback attributes (modularity, PageRank, eigenvector centrality, clustering coefficient, weighted in degree, weighted outdegree, weighted degree) which also obtained from the SNA of the corresponding dataset. Given the right hyperparameter settings, we observed RS improvement in term of RMSE (root mean square error) in the three cases. In this paper, three RS models: SVD, SVD++, and difference SVD are used. Besides discussing the RS performance, we also discuss the computational cost incurred from incorporating those implicit feedbacks.
Vocal Repertoire in the Dhole Cuon alpinus (Carnivora, Canidae) in Captivity

Three independent structural components form the dhole vocal repertoire: low tonal, high tonal, and pulsed. The repertoire was divided into three vocal classes and eleven call types based on the occurrence of these components. Two broadband signals with a pronounced pulsed pattern were referred to the pulsed vocal class. Two vocal types involving the high component within the band 6-9 kHz were assigned to the class with the component of high frequency. The other seven types with a distinct component of low frequency were positioned to the class of tonal signals. The vocal components differed by their contribution to the structural variability of the vocal reper- toire as a whole. The high variability of the low tonal component results in a structural radiation to a few vocal types, whereas both high tonal and pulsed components follow the "one or zero" principle, i.e. a component is pres- ent or absent. The fact that different components may be produced simultaneously makes it possible to suppose that they arise from various vocal sources. A general scheme of structural transitions between different vocal types in the dhole has been developed on the basis of the structural analysis of signals and their relation to a certain situa- tion.
Design and measurements of 10 bit pipeline ADC for the Luminosity Detector at ILC

The design and the preliminary measurements of a prototype 10 bit pipeline ADC based on 1.5-bit per stage architecture, developed for the luminosity detector at International Linear Collider (ILC) are presented. The ADC is designed in two versions, with and without a sample-and-hold circuit (S/H) at the input. The prototypes are fabricated in 0.35 μm CMOS technology. A dedicated test setup with a fast FPGA based data acquisition system (DAQ) is developed for the ADC testing. The measurements of static (INL, DNL) and dynamic parameters are performed to understand and quantify the circuit performance. The integral (INL) and differential (DNL) nonlinearity are below 1 LSB and 0.5 LSB respectively. The dynamic measurements show signal to noise (SNHR) ratio of about 58 dB for sampling frequency up to 25 MHz.
Hypoxia and Chromatin: A Focus on Transcriptional Repression Mechanisms

Hypoxia or reduced oxygen availability has been studied extensively for its ability to activate specific genes. Hypoxia-induced gene expression is mediated by the HIF transcription factors, but not exclusively so. Despite the extensive knowledge about how hypoxia activates genes, much less is known about how hypoxia promotes gene repression. In this review, we discuss the potential mechanisms underlying hypoxia-induced transcriptional repression responses. We highlight HIF-dependent and independent mechanisms as well as the potential roles of dioxygenases with functions at the nucleosome and DNA level. Lastly, we discuss recent evidence regarding the involvement of transcriptional repressor complexes in hypoxia.
Solving Conceptual and Perceptual Analogies with Virtual Reality among Kindergarten Children of Immigrant Families

Background The ability to think analogically is central to the process of learning and understanding reality and there is a broad consensus among researchers that we can improve this ability. Immigrants who have emigrated from developing to developed countries tend to experience tremendous challenges in their early years as immigrants. Their children often find themselves in a situation where it is clear that their low achievements are the result of cultural mediation, which expresses itself not only in a language gap, but also in cultural and basic technological disorientation. Purpose The goal of this study is to help find efficient ways of nurturing analogical thinking in children who have emigrated from developing to developed countries and express difficulties in analogical thinking, and to point out the advantages inherent in the use of immersive 3D Virtual Reality technology for this goal. Population The participants in this study included 56 children, aged 4 to 7 years, whose parents immigrated to Israel from Ethiopia during the last ten years. The experimental group (n=28) practiced solving analogies that were presented in 3D VR, while the control group (n=28) practiced solving the same analogies with a pictorial version of the items that was presented with cards. Research Design The research instrument employed for evaluating Analogical thinking was the CCPAM measure, which includes 10 questions on Conceptual Analogies and 10 questions on Perceptual analogies. We designed the intervention program according to the CCPAM test. The CCPAM test was administered in three intervals: a. Prior to the beginning of the intervention. b. Immediately after the intervention, which included two meetings of 15 minutes each, during which the children were given exercises in solving analogies. c. Three weeks after the end of the intervention, in order to test the ability to preserve the solution strategy (the follow-up test). Conclusions The results indicate that both programs of intervention—VR and picture cards— significantly improved the ability to solve both kinds of analogies—perceptual and conceptual. However, the children in the experimental group, who practiced analogies within an immersive VR environment, improved their ability to a statistically significant degree more than did the children who practiced solutions with picture cards. The children in the experimental group preserved the solution strategy three weeks after the intervention significantly better than the control group, and the improvement in solving conceptual analogies was greater than the improvement in solving perceptual analogies.
