Practical privacy-preserving user profile matching in social networks

In this paper, we consider a scenario where a user queries a user profile database, maintained by a social networking service provider, to find out some users whose profiles are similar to the profile specified by the querying user. A typical example of this application is online dating. Most recently, an online data site, Ashley Madison, was hacked, which results in disclosure of a large number of dating user profiles. This serious data breach has urged researchers to explore practical privacy protection for user profiles in online dating. In this paper, we give a privacy-preserving solution for user profile matching in social networks by using multiple servers. Our solution is built on homomorphic encryption and allows a user to find out some matching users with the help of the multiple servers without revealing to anyone privacy of the query and the queried user profiles. Our solution achieves user profile privacy and user query privacy as long as at least one of the multiple servers is honest. Our implementation and experiments demonstrate that our solution is practical.
Understanding Participation of Preschool-Age Children With Cerebral Palsy

Participation in home, school, and community activities is a primary outcome of early intervention services for children with disabilities and their families. The objectives of this study were to (a) describe participation of preschool-age children with cerebral palsy (CP); (b) determine effects of sex, age, and gross motor function on intensity of participation; and (c) identify child, family, and service determinants of intensity of participation. A convenience sample of 85 preschool-age children with CP and their parents participated. Parents completed self-report measures on children’s participation, adaptive behavior, physical function, family functioning, and services. Children’s Gross Motor Function Classification System levels (Palisano, Rosenbaum, Bartlett, & Livingston, 2008) were determined by assessors. A multiple linear regression analysis was conducted to determine the variance in intensity of participation explained by the determinants. Children with limited self-mobility had a lower intensity of participation than children with independent upright mobility. Adaptive behavior, transfers and basic mobility function, and upper extremity and physical function explained 46% of the variance of intensity of participation.
Evaluation of Passively Transferred, Nonneutralizing Antibody-Dependent Cellular Cytotoxicity-Mediating IgG in Protection of Neonatal Rhesus Macaques against Oral SIVmac251 Challenge1

Previously, Ab-dependent cellular cytotoxicity (ADCC) was significantly correlated with reduced acute viremia upon intrarectal SIVmac251 challenge of immunized rhesus macaques. To directly assess ADCC protective efficacy, six neonatal macaques were infused s.c. with immune IgG (220 mg/kg) purified from the immunized animals and positive for ADCC and Ab-dependent cell-mediated viral inhibition (ADCVI) activities. Six neonates received control IgG. The neonates were challenged twice orally with 105 50% inhibiting tissue culture-infective dose of SIVmac251 2 days post-IgG infusion. At challenge, plasma of neonates that received immune IgG did not neutralize SIVmac251 but had geometric mean ADCC titers of 48,130 and 232,850 against SIVmac251-infected and gp120-coated targets, respectively. Peak ADCVI activity varied from 62 to 81%. ADCC activity declined with the 2-wk IgG half-life but was boosted at wk 4, together with de novo ADCC-mediating Abs in controls, by postchallenge viremia. ADCVI activity was similarly induced. No protection, assessed by viral burdens, CD4 counts, and time to euthanasia was observed. Possible factors contributing to the discrepancy between the previous correlation and lack of protection here include: the high oral challenge dose compared with the 400-fold lower intrarectal dose; the challenge route with regard to viral dissemination and distribution of infused IgG; insufficient NK effector activity and/or poor functionality in newborns; insufficient immune IgG; and the possibility that the previous correlation of ADCC with protection was augmented by cellular immune responses also present at challenge. Future studies should explore additional challenge routes in juvenile macaques using higher amounts of potent IgG preparations.
Microbial Reduction of Crystalline Iron(III) Oxides: Influence of Oxide Surface Area and Potential for Cell Growth

Quantitative aspects of microbial crystalline iron(III) oxide reduction were examined using a dissimilatory iron(III) oxide-reducing bacterium (Shewanella alga strain BrY). The initial rate and long-term extent of reduction of a range of synthetic iron(III) oxides were linearly correlated with oxide surface area. Oxide reduction rates reached an asymptote at cell concentrations in excess of ≈1 × 109/m2 of oxide surface. Experiments with microbially reduced goethite that had been washed with pH 5 sodium acetate to remove adsorbed Fe(II) suggested that formation of a Fe(II) surface phase (adsorbed or precipitated) limited the extent of iron(III) oxide reduction. These results demonstrated explicitly that the rate and extent of microbial iron(III) oxide reduction is controlled by the surface area and site concentration of the solid phase. Strain BrY grew in media with synthetic goethite as the sole electron acceptor. The quantity of cells produced per micromole of goethite reduced (2.5 × 106) was comparable .
Wilderness Writing: Using Personal Narrative to Enhance Outdoor Experience

While writing is used to enhance learning in many outdoor programs, it is rarely used as a method for focused self-exploration. A partnership between a recreation professor and a writing teacher provides the training to have both a solid outdoor program and a solid experience in personal narrative in journals and essays. Students participating in such a combined program benefit by a) learning technical outdoor skills and a process of self-discovery, and b) experiencing the complete writing process, and building a cohesive discourse community. Educators desiring to design an outdoor writing program can make goals, design a program, create a curriculum, and establish a process of program review.
Estimation and Prediction for Stochastic Blockstructures

A statistical approach to a posteriori blockmodeling for digraphs and valued digraphs is proposed. The probability model assumes that the vertices of the digraph are partitioned into several unobserved (latent) classes and that the probability distribution of the relation between two vertices depends only on the classes to which they belong. A Bayesian estimator based on Gibbs sampling is proposed. The basic model is not identified, because class labels are arbitrary. The resulting identifiability problems are solved by restricting inference to the posterior distributions of invariant functions of the parameters and the vertex class membership. In addition, models are considered where class labels are identified by prior distributions for the class membership of some of the vertices. The model is illustrated by an example from the social networks literature (Kapferer's tailor shop).
Changes in Mobility Account for Camptothecin-induced Subnuclear Relocation of Topoisomerase I* 210

DNA topoisomerase I is a nucleolar protein, which relocates to the nucleoplasm in response to drugs stabilizing topoisomerase I·DNA intermediates (e.g. camptothecin). Here we demonstrate that this phenomenon is solely caused by the drug's impact on the interplay between mobility and localization of topoisomerase I in a living cell nucleus. We show by photobleaching of cells expressing biofluorescent topoisomerase I-chimera that the enzyme moves continuously between nucleoli and nucleoplasm. Complex kinetics of fluorescence recovery after photobleaching indicates that two enzyme fractions with different mobility coexist in nucleoli and nucleoplasm. However, the whole complement of topoisomerase I is in continuous flux between these compartments and nucleolar accumulation can plausibly explained by the enzyme's 2-fold lesser overall mobility in nucleoli versus nucleoplasm. Upon addition of camptothecin, topoisomerase I relocates within 30 s from the nucleoli to radial nucleoplasmic structures. At these sites, the enzyme becomes retarded in a dose-dependent manner. Inside nucleoli the mobility of topoisomerase I is much less affected by camptothecin. Thus, the enzyme's distribution equilibrium is shifted toward the nucleoplasm, which causes nucleolar delocalization. In general, topoisomerase I is an entirely mobile nuclear component, unlikely to require specific signaling for movements between nuclear compartments.
An Instruction Issuing Approach to Enhancing Performance in Multiple Functional Unit Processors

Processors with multiple functional units, such as CRAY-1, Cyber 205, and FPS 164, have been used for high-end scientific computation tasks. Much effort has been put into increasing the throughput of such systems. One critical consideration in their design is the identification and implementation of a suitable instruction issuing scheme. Existing approaches do not issue enough instructions per machine cycle to fully utilize the functional units and realize the high-performance level achievable with these powerful execution resources.
Mapping Prefrontal Circuits In Vivo with Manganese-Enhanced Magnetic Resonance Imaging in Monkeys

Manganese-enhanced magnetic resonance imaging (MEMRI) provides a powerful tool to study multisynaptic circuits in vivo and thereby to link information about neural structure and function within individual subjects. Making the best use of MEMRI in monkeys requires minimizing manganese-associated neurotoxicity, maintaining sensitivity to manganese-dependent signal changes and mapping transport throughout the brain without a priori anatomical hypotheses. Here, we performed intracortical injections of isotonic MnCl2, comparisons of preinjection and postinjection scans, and voxelwise statistical mapping. Isotonic MnCl2 did not cause cell death at the injection site, damage to downstream targets of manganese transport, behavioral deficits, or changes in neuronal responsiveness. We detected and mapped manganese transport throughout cortical–subcortical circuits by using voxelwise statistical comparisons of at least 10 preinjection and two postinjection scans. We were able to differentiate between focal and diffuse projection fields and to distinguish between the topography of striatal projections from orbitofrontal and anterior cingulate cortex in a single animal. This MEMRI approach provides a basis for combining circuit-based anatomical analyses with simultaneous single-unit recordings and/or functional magnetic resonance imaging in individual monkeys. Such studies will enhance our interpretations of functional data and our understanding of how neuronal activity is transformed as it propagates through a circuit.
EMBRACE: A Multi-Beam 20,000-Element Radio Astronomical Phased Array Antenna Demonstrator

We present the design and development of the electronic multi-beam radio astronomy concept (EMBRACE), a demonstrator that is part of the European contribution towards the square kilometre array, which is currently being designed by the global radio astronomical community. One of the design goals of EMBRACE is to demonstrate the applicability of phased array technology for use in future radio telescopes. The EMBRACE system will ultimately consist of two stations, the largest of which comprises over 20,000 elements and has a physical area of about 160 m2 . The antenna system, covering the 500-1500 MHz frequency range, is designed as a dual polarized system, however only the signals for one polarization are processed. To obtain a cost effective design, RF analog beam-forming is performed on tile level close to the radiators. The demonstrator is designed to provide two independent beams such that different parts of the sky can be observed simultaneously. First results from part of the array are presented and discussed. The results show that the complete data path is functional. Since the design resembles a large regular contiguous array, all coupling can be taken into account in the embedded element patterns. The array factor therefore suffices to describe the scanning of the array reducing significantly calibration complexity compared to, e.g. sparse, random or more irregular arrays. This is confirmed by the first array factor measurements, that were done using a novel technique that does not require calibration of the array. The first measurements on an astronomical source, the Sun, indicate that the system noise temperature lies between 104 and 118 K, which is reassuringly close to the design target of 100 K.
Improving blood transfusion practice: role of a computerized hospital information system

The recent focus on medical risk and financial cost has prompted a need for better guidelines for prescribing the transfusion of blood components. In 1987, to respond to the issues of quality transfusion practice and accurate evaluation, LDS Hospital (Salt Lake City, UT) began using a computerized, knowledge‐based blood‐ordering system. Each transfusion request was reviewed and flagged by the computer when it did not meet the criteria established by the medical staff. The study reviewed the use of red cells, platelets, and fresh‐frozen plasma in 13,082 transfusion orders for 5847 consecutive patients from July 1, 1988, through June 30, 1989. The evaluation assessed, first, the adherence of physicians to computerized criteria and, second, their adherence to the quality of transfusion practice. A high percentage of the blood units ordered met the established criteria: 91.2 percent for the red cell transfusions, 72.9 percent for platelets, and 81.7 percent for fresh‐frozen plasma. From the July 1, 1987, implementation date through June 1989, the mean hematocrit of persons being transfused dropped from 28.6 to 27.7 percent (0.29 = 0.28) (p less than 0.005) and the number of orders requiring review by the quality assurance department dropped from 100 to 14 percent; moreover, there was a true‐ exception rate of only 0.37 percent. The use of the computer system effected the implementation of the following measures: 1) identification of the indications and establishment of clear clinical and biologic parameters for every transfusion, and 2) measurement and improvement of institutional transfusion practice. These results demonstrated the efficacy of a computerized hospital information system in implementing continuous quality improvement for transfusion practice. (ABSTRACT TRUNCATED AT 250 WORDS)

Advanced GTCF-LARC Contouring Motion Controller Design for an Industrial X–Y Linear Motor Stage With Experimental Investigation

In this paper, a global task coordinate frame (GTCF)-based learning adaptive robust contouring controller is proposed for an industrial X–Y linear-motor-driven stage to achieve not only good parametric adaptation ability and disturbance robustness, but also excellent contouring accuracy even under high-speed large-curvature contouring tasks. Specifically, the contouring controller employs GTCF to guarantee the multiaxes motion coordination. After transforming the system dynamics of the X–Y linear-motor-driven stage into the GTCF, a learning adaptive robust control (LARC) scheme is developed to deal with the strongly coupled dynamics under parametric uncertainty and uncertain disturbances. During the LARC, adaptive model compensation term, robust feedback term, and iterative learning term are organically integrated in a serial structure. The controller design process with the stability analysis is presented, while the essence of the practical achievable performance is also introduced for the nature of the GTCF-LARC. Comparative experiments are carried out on an industrial linear-motor-driven stage with different cases. The results consistently verify that the proposed GTCF-LARC contouring controller can simultaneously meet the industrial requirements of excellent transient/steady-state contouring accuracy, parametric adaptation ability, external disturbance robustness, and large-curvature high-speed contouring tasks. The proposed GTCF-LARC scheme actually provides a practical high-performance-oriented contouring control framework, and could be extended to other multiaxes applications.
Learning Strategies Assessed by Journal Writing: Prediction of Learning Outcomes by Quantity, Quality, and Combinations of Learning Strategies

Recently, there have been efforts to rethink assessment. Instead of informing about (relatively stable) learner characteristics, assessment should assist instruction by looking at the learning process, facilitating feedback about what students' next step in learning could be. Similarly, new forms of strategy assessment aim at capturing self-regulated learning as it happens. One potential method for such assessment is the learning journal. We analyzed whether (a) quantity and (b) quality of learning strategies assessed by learning journals predict learning outcomes, and (c) whether differently successful combinations of strategies can be identified. In Study 1, 9th graders of medium-track high schools (N = 236) wrote learning journals in mathematics during 6 weeks. Foremost, quality and quantity of cognitive strategies predicted learning outcomes, controlling for prior knowledge. Learners who combined cognitive plus metacognitive strategies were particularly successful. Learners who mainly used 1 type of strategy performed similarly poorly as did learners who hardly used strategies. Study 2 in the domain of biology learning (N = 144) essentially replicated these findings. In summary, learning journals are a useful and innovative method for assessing learning strategies.
Experimental analysis of buried SiGe pMOSFETs from the perspective of aggressive voltage scaling

This study aims to understand the potential of buried Silicon-Germanium (SiGe) technology from the perspective of VLSI logic circuits exploiting aggressive dynamic voltage scaling. Appropriate circuit- and system-level metrics are extracted from wafer-level measurements on 45nm SiGe pMOSFETs with a high-k/metal gate stack and systematically benchmarked to Si channel devices. The comparative analysis shows that the SiGe technology has more efficient leakage-delay and dynamic energy-delay trade-offs at nominal supply. These advantages of SiGe VLSI circuits are further emphasized at low voltages. This demonstrates that SiGe VLSI circuits benefit from aggressive voltage scaling significantly more than Si circuits, thereby making SiGe pMOSFET a mature candidate to substitute Si transistor for VLSI system implementations in future technology nodes.
The Large Tegument Protein pUL36 Is Essential for Formation of the Capsid Vertex-Specific Component at the Capsid-Tegument Interface of Herpes Simplex Virus 1

ABSTRACT Herpesviruses have a characteristic particle structure comprising an icosahedral capsid, which contains the DNA genome and is, in turn, surrounded by a proteinaceous tegument layer and a lipid envelope. In herpes simplex virus, the interaction between the capsid and tegument is limited to the capsid vertices and involves two minor capsid proteins, pUL17 and pUL25, and the large inner tegument protein pUL36. pUL17 and pUL25 form a heterodimeric structure, the capsid vertex-specific component (CVSC), that lies on top of the peripentonal triplexes, while pUL36 has been reported to connect the CVSC to the penton. In this study, we used virus mutants with deletions in the genes for pUL36 and another inner tegument protein, pUL37, to analyze the contributions of these proteins to CVSC structure. Using electron cryomicroscopy and icosahedral reconstruction of mutants that express pUL17 and pUL25 but not pUL36, we showed that in contrast to accepted models, the CVSC is not formed from pUL17 and pUL25 on their own but requires a contribution from pUL36. In addition, the presence of full-length pUL36 results in weak density that extends the CVSC toward the penton, suggesting either that this extra density is formed directly by pUL36 or that pUL36 stabilizes other components of the vertex-tegument interface. IMPORTANCE Herpesviruses have complex particles that are formed as a result of a carefully controlled sequence of assembly steps. The nature of the interaction between two of the major particle compartments, the icosahedral capsid and the amorphous tegument, has been extensively studied, but the identity of the interacting proteins and their roles in forming the connections are still unclear. In this study, we used electron microscopy and three-dimensional reconstruction to analyze virus particles formed by mutants that do not express particular interacting proteins. We show that the largest viral protein, pUL36, which occupies the layer of tegument closest to the capsid, is essential for formation of structurally normal connections to the capsid. This demonstrates the importance of pUL36 in the initial stages of tegument addition and provides new insights into the process of virus particle assembly.
Spiritual Maturation and Religious Behaviors in Christian University Students

Spiritual maturation processes of internalization and questing were assessed at a Christian university to determine their relationship to year in school and certain religious behaviors. This was a first step toward the development of a new model of Christian higher education that will intentionally facilitate spiritual maturation. A group of 179 university students, ranging in age from 17 to 25 years and representing all four undergraduate classes, completed measures of spiritual maturation. The group of 75 males and 104 females professing Christian faith completed the Quest Scale (Batson & Schoenrade, 1991), Religious Orientation Scale (Gorsuch & McPherson, 1989), and Christian Religious Internalization Scale (Ryan, Rigby, & King, 1993). Multivariate analysis of variance and multiple regression statistical procedures were used to assess these spiritual maturation processes across year in school, gender, upper and lower class status, and religious behavior levels. The study found that year in school and class status were significantly and positively related to questing processes. Results also showed that religious behaviors were significantly and positively related to internalization processes. In addition, women showed significantly greater internalization than men. The study provides support for a new model of spiritual maturation for Christian university students.
Elite Social Relations and Corporate Political Donations in Britain

Elite theory critiques of corporate political action rest on the claim that it advances the political interests of elite status groups. This article examines that claim by investigating the relationship between a British corporation's propensity to make donations to the Conservative party and its directors' educational backgrounds and social club affiliations. Using a structural equivalence blockmodel, it is shown that among the largest 250 British corporations in 1995 there was a set with directors who came from elite educational backgrounds and were members of elite social clubs. These corporations made a disproportionate number of donations. I argue that these results support the elite theory critique.
