Margin Perceptrons for Graphs

This contribution extends linear classifiers to sub-linear classifiers for graphs and analyzes their properties. The results are (i) a geometric interpretation of sub linear classifiers, (ii) a generic learning rule based on the principle of empirical risk minimization, (iii) a convergence theorem for the margin perceptron in the separable case, and (iv) the VC-dimension of sub linear functions. Empirical results on graph data show that the perceptron and margin perceptron algorithm on graphs have similar properties as their vectorial counterparts.
Inhibition of platelet adhesion to collagen by monoclonal anti‐CD36 antibodies

Monoclonal anti CD36 antibodies capable of inhibiting platelet adhesion to collagen have not previously been identified. We have now prepared two groups of monoclonal antibodies. One group was prepared using, as immunogen, highly purified (99+%) CD36 prepared by a denaturing procedure. These antibodies (Mo series) reacted strongly with CD36 on protein blots but did not immunoprecipitate native CD36 from platelet lysates nor inhibit platelet adhesion to collagen. The second group of monoclonal antibodies (131 series) was prepared using CD36 purified to >95% by a non‐denaturing procedure. These antibodies reacted with control platelets, but not Naka‐negative platelets which lack CD36, as measured by flow cytometry and by immunoprecipitation. Three monoclonal antibodies of this latter group (131.4, 131.5 and 131.7) inhibited platelet adhesion to collagen in static systems under Mg2+‐independent conditions but had little effect in the presence of Mg2+. 131.4 and 131.7 also inhibited adhesion to collagen using citrated whole blood in a parallel plate flow chamber at physiological shear rates (800 s−1), whereas 131.5 was without effect. These are the first anti‐CD36 monoclonal antibodies shown to be capable of inhibiting platelet adhesion to collagen and provide further evidence that CD36 plays a role in platelet–collagen interaction.
Investor's Dilemma: Fundamentals or Biasness in Investment Decision

In the present world Investment decision is most important phenomena. Investment is current sacrifice for future benefits, So while making investment decisions we have to keep different things in mind. Investment decisions are influenced not only by their fundamentals but also depend on different factors. One factor is the biasness of any investor to their investment, biasness depends on the cognition and emotions, because some investors use them as heuristic for the investment decision instead of fundamentals. Keeping this in view, this paper shows how cognitive biasness (i.e. Representativeness, Adjustment and Anchoring, Leniency) effects the investment decisions over the fundamentals. This study also show different types of investors which depicts significant relation of Representativeness, Adjustment and Anchoring, Leniency with investment decisions over fundamentals, and explain under which biasness an investor become more optimistic and moderate for investment decisions. While considering Representativeness biasness over fundamentals investor become more optimistic, In Adjustment and Anchoring biasness investor show moderate behavior about investment decision, and In Leniency biasness investor also take investment decision over optimistically.
An NMR study on the intrinsically disordered core transactivation domain of human glucocorticoid receptor

A large number of transcriptional activation domains (TADs) are intrinsically unstructured, meaning they are devoid of a three-dimensional structure. The fact that these TADs are transcriptionally active without forming a 3-D structure raises the question of what features in these domains enable them to function. One of two TADs in human glucocorticoid receptor (hGR) is located at its N-terminus and is responsible for ~70% of the transcriptional activity of hGR. This 58-residue intrinsically-disordered TAD, named tau1c in an earlier study, was shown to form three helices under trifluoroethanol, which might be important for its activity. We carried out heteronuclear multi-dimensional NMR experiments on hGR tau1c in a more physiological aqueous buffer solution and found that it forms three helices that are ~30% pre-populated. Since pre-populated helices in several TADs were shown to be key elements for transcriptional activity, the three pre-formed helices in hGR tau1c delineated in this study should be critical determinants of the transcriptional activity of hGR. The presence of pre-structured helices in hGR tau1c strongly suggests that the existence of pre-structured motifs in target-unbound TADs is a very broad phenomenon.
Which Comparison Standard Should Be Used for Service Quality and Customer Satisfaction?

SUMMARY The aim of this study is to examine whether consumers use single or multiple comparison standards for the evaluation of service quality and when determining their satisfaction, in the context of the hospitality industry. The data was collected using a convenient student sample. The findings indicate that consumers use multiple comparison standards for the evaluation of service quality and satisfaction. Five of the eight tested comparison standards are found to be significant in predicting service quality and satisfaction. Of these, predictive expectations, deserved expectation, desires congruence and experience-based norm are considered very important. The study also suggests that service quality and customer satisfaction are different constructs and survey instruments should take into account this difference in measurement.

The purpose of this document is to present analytical formulas for the inflation caps and floors (year on year and zero-coupon). The framework of the note is the forward price index market model. This technical note is complementary to Zine-eddine (2013b), and consequently reuses the same notations and definitions, particularly for the price index and the forward price index.
A simple and robust algorithm for microarray data clustering based on gene population‐variance ratio metric

With the advent of the microarray technology, the field of life science has been greatly revolutionized, since this technique allows the simultaneous monitoring of the expression levels of thousands of genes in a particular organism. However, the statistical analysis of expression data has its own challenges, primarily because of the huge amount of data that is to be dealt with, and also because of the presence of noise, which is almost an inherent characteristic of microarray data. Clustering is one tool used to mine meaningful patterns from microarray data. In this paper, we present a novel method of clustering yeast microarray data, which is robust and yet simple to implement. It identifies the best clusters from a given dataset on the basis of the population of the clusters as well as the variance of the feature values of the members from the cluster‐center. It has been found to yield satisfactory results even in the presence of noisy data.
Forecasting Housing Markets: Lessons Learned

Forecasting changes in housing finance (instruments and institutions), housing demand (tenure, quantity, and real price), and housing production requires forecasting numerous exogenous factors—inflation, government policy, and demographic forces being the most obvious—and interpreting their impacts on the housing market. We use forecasts made over the last two decades to illustrate the importance of these variables and of interpreting their impacts appropriately.
Neural progenitors, neurogenesis and the evolution of the neocortex

The neocortex is the seat of higher cognitive functions and, in evolutionary terms, is the youngest part of the mammalian brain. Since its origin, the neocortex has expanded in several mammalian lineages, and this is particularly notable in humans. This expansion reflects an increase in the number of neocortical neurons, which is determined during development and primarily reflects the number of neurogenic divisions of distinct classes of neural progenitor cells. Consequently, the evolutionary expansion of the neocortex and the concomitant increase in the numbers of neurons produced during development entail interspecies differences in neural progenitor biology. Here, we review the diversity of neocortical neural progenitors, their interspecies variations and their roles in determining the evolutionary increase in neuron numbers and neocortex size.
Performance analysis of flexible hierarchical cellular systems with a bandwidth-efficient handoff scheme

In this paper, a bandwidth-efficient handoff strategy is proposed and analyzed for hierarchical cellular systems. Mobile subscribers are divided into two classes, i.e., low- and high-mobility subscribers. In our bandwidth-efficient handoff strategy, each of the originating and handoff calls of both slow and fast mobile subscribers first tries to get a channel in a microcell. Macrocells are overlaid over the microcells to handle overflowed calls. A call overflowed into a macrocell requests a take-back to the new microcell at each border crossing of the microcells. The request will be accommodated by the target microcell if there is any idle traffic channel in the cell. An analytical model is developed, and the most important performance measures such as the blocking probability of originating calls and the forced termination probability of calls are evaluated. It is shown through extensive comparisons with other candidate handoff strategies that if the total traffic load of the system is not very heavy, our scheme has the best bandwidth efficiency and can provide better quality of service for mobile subscribers without bringing too much processing expense to the system.
Calculation of wire motion in a superconducting magnet

The wire dynamic simulation has been performed in the superconducting magnet to get the selection standard of structural materials for stable magnet. The equation of motion of each winding was solved with time to simulate the wire motion in a superconducting magnet. The transport current was increased with time, and hence applied force to the wire was changed with time. The minimum quench energy of each winding was calculated and compared with the frictional heating. The quench current was decided when the frictional heating was more than MQE. The material parameters and the winding tension were changed and the wire motion in a superconducting magnet was analyzed.
Architectonic subdivision of the orbital and medial prefrontal cortex in the macaque monkey

The orbital and medial prefrontal cortex (OMPFC) of macaque monkeys is a large but little understood region of the cerebral cortex. In this study the architectonic structure of the OMPFC was analyzed with nine histochemical and immunohistochemical stains in 32 individuals of three macaque species. The stains included Nissl, myelin, acetylcholinesterase, Timm, and selenide stains and immunohistochemical stains for parvalbumin, calbindin, a nonphosphorylated neurofilament epitope (with the SMI‐32 antibody), and a membrane‐bound glycoprotein (with the 8b3 antibody). In addition to patterns of cell bodies and myelinated fibers, these techniques allow the visualization of markers related to metabolism, synapses, and neurotransmitters. A cortical area was defined as distinct if it was differentiated in at least three different stains and, as described in later papers, possessed a distinct set of connections. Twenty‐two areas were recognized in the OMPFC. Walker's areas 10, 11, 12, 13, and 14 [J. Comp. Neurol. (1940) 73:59–86] have been subdivided into areas 10m, 10o, 11m, 11l, 12r, 12l, 12m, 12o, 13m, 13l, 13a, 13b, 14r, and 14c. On the medial wall, areas 32, 25, and 24a, b, c have been delineated, in addition to area 10m. The agranular insula also has been recognized to extend onto the posterior orbital surface and has been subdivided into medial, intermediate, lateral, posteromedial, and posterolateral agranular insula areas. The OMPFC, therefore, resembles other areas of primate cortex, such as the posterior parietal and temporal cortices, where a large number of relatively small, structurally and connectionally distinct areas have been recognized. Just as the area‐specific neurophysiological properties of these parietotemporal areas underlie broader regional functions such as visuospatial analysis, it is likely that the many small areas of the OMPFC also make differential contributions to the general mnemonic, sensory, and affective functions of this region. © 1994 Wiley‐Liss, Inc.
A User Community-Based Approach to Leveraging Technological Competences: An Exploratory Case Study of a Technology Start-Up from MIT

Many studies highlight the impact of technology commercialization on innovation and wealth creation. However, this impact could be far greater, especially as many technologies developed with high costs and effort remain vastly underutilized. One important reason for this problem can be found at the front end of the technological competence leveraging process: searching for market opportunities for a technology is a formidable challenge. In many cases, alternative fields of application (or even a single viable market opportunity) for a given technology are simply unknown to the entity in charge of commercialization. Based on an extensive literature review, we identify two major shortcomings at the front end of the technological competence leveraging process which contribute to the underutilization problem: (1) the local search behaviour of the commercializing entity and (2) the use of solution-based instead of problem-based search specifications. On the basis of these insights, we discuss the potential role of user communities in the search for (additional) market opportunities for a given technology, a process usually referred to as technological competence leveraging. We then empirically explore a user community-based approach in an illustrative case study with a start-up from MIT. Our findings show that when users were included in the search process, the number of potential markets in which the technology could be applied was five times higher, and more far-distant application areas as well as application areas previously unknown to the technology holder were reached. In addition, we discover design principles for a user community-based search process, providing practitioners with a hands-on guideline for employing a user community-based approach to technological competence leveraging.
The Delay of Gastric Emptying Induced by Remifentanil Is Not Influenced by Posture

Posture has an effect on gastric emptying. In this study, we investigated whether posture influences the delay in gastric emptying induced by opioid analgesics. Ten healthy male subjects underwent 4 gastric emptying studies with the acetaminophen method. On two occasions the subjects were given a continuous infusion of remifentanil (0.2 μg · kg−1 · min−1) while lying either on the right lateral side in a 20° head-up position or on the left lateral side in a 20° head-down position. On two other occasions no infusion was given, and the subjects were studied lying in the two positions. When remifentanil was given, there were no significant differences between the two postures in maximal acetaminophen concentration (right side, 34 μmol · L−1; versus left side, 16 μmol · L−1), time taken to reach the maximal concentration (94 versus 109 min), or area under the serum acetaminophen concentration time curve from 0 to 60 min (962 versus 197 min · μmol · L−1). In the control situation, there were differences between the postures in maximal acetaminophen concentration (138 versus 94 μmol · L−1; P <0.0001) and area under the serum acetaminophen concentration time curves from 0 to 60 min (5092 versus 3793 min · μmol · L−1; P <0.0001), but there was no significant difference in time taken to reach the maximal concentration (25 versus 47 min). Compared with the control situation, remifentanil delayed gastric emptying in both postures. We conclude that remifentanil delays gastric emptying and that this delay is not influenced by posture.
Biological and molecular characterization of Besnoitia akodoni n.sp. (Protozoa: Apicomplexa) from the rodent Akodon montensis in Brazil.

The diversity among coccidian parasites of the genus Besnoitia is incompletely known. Of the eight currently described members of the genus, only B. jellisoni is known to parasitize a rodent host. Here, we propose a new name, Besnoitia akodoni, for the species initially isolated form the rodent Akodon montensis in Brazil. The tissue cysts of B. akodoni were up to 442 microm in diameter and bradyzoites were 8.4 x 1.4 microm in size. The bradyzoites contained enigmatic bodies, micronemes and rhoptries. Tachyzoites were 5.8 x 1.5 microm in size and they could be grown in vitro in bovine monocytes and African Green monkey cells where they divided by endodyogeny. Besnoitia akodoni was infective to laboratory-raised mice (Mus musculus) and gerbils (Meriones unguiculatus) but not to cats (Felis catus). Comparison of the conserved sequences of the small subunit rDNA clearly established the close relationship of B. akodoni with other members of the genus. However, sequences of the more variable first internal transcribed spacer portion of the ribosomal DNA repeat support its differentiation from the other species of the genus.
The Becke Fuzzy Cells Integration Scheme in the Amsterdam Density Functional Program Suite

In this article, we document a new implementation of the fuzzy cells scheme for numerical integration in polyatomic systems [Becke, J. Chem. Phys. 1998, 88, 2547] and compare its efficiency and accuracy with respect to an integration scheme based on the Voronoi space partitioning. We show that the accuracy of both methods is comparable, but that the fuzzy cells scheme is better suited for geometry optimization. For this method, we also introduce the locally dense grid concept and present a proof‐of‐concept application. © 2013 Wiley Periodicals, Inc.
Local Fasciocutaneous Flaps for Olecranon Coverage

In 1989 we began to treat soft-tissue defects around the olecranon process with local fasciocutaneous flaps as our preferred method of treatment. These soft-tissue defects are complications of bursitis, degenerative joint disease, and burns. They may also result from pressure necrosis over the olecranon in patients with impaired sensation. Because of the difficulty in treating these wounds a variety of local muscle, musculocutaneous, fasciocutaneous, distant, and free flaps have been described. Fasciocutaneous flaps have the advantage of using regional tissue in a single stage. Fasciocutaneous flaps around the elbow can be categorized as proximally or distally based. Proximally based flaps include the radial and ulnar forearm flaps as well as the posterior interosseous flap. Distally based flaps are based on upper elbow collaterals including the radial collateral artery, the middle collateral artery, and the anterior and posterior ulnar recurrent arteries. Eleven fasciocutaneous flaps were used in 10 patients with a follow-up of 1 to 3 years. All flaps survived and provided primary wound closure. Complications included 1 patient with recurrent ulceration after being healed for 6 months and 1 patient with a transient neurapraxia of the posterior interosseous nerve that resolved after 2 weeks. These flaps provide long-term stable coverage of olecranon wounds by using regional tissue with an acceptable donor site morbidity.

Flexible Architecture of Ultra-Low-Power Current-Mode Interleaved Successive Approximation Analog-to-Digital Converter for Wireless Sensor Networks

A novel 8-bit current mode interleaved successive approximation (SAR) analog-digital converter (ADC) has been proposed. The proposed converter architecture is very flexible. Using two control DC voltages and one reference current, the converter can be tuned to work with different sampling rates, number of bits of resolution, and power consumption levels. Due to its very low-power consumption and flexibility, the converter is particularly suitable for application in wireless sensor networks. Compared to other solutions presented in the literature, the proposed converter achieves very high figure of merit (FOM) value due to numerous low-power circuit innovations utilized in its design. The circuit has been implemented in CMOS 0.18 µm technology. Minimum energy consumption has been found to be in a 25-250 kS/s range (for clock sampling frequency in a 200 kHz-2MHz range) for a single SAR section with the corresponding power dissipation varying from 220 nW to 560 nW for 0.55 V power supply.
Empowered service delegation with attribute encryption for distributed cloud computing

Cloud computing has emerged as one of the most influential paradigms in the IT industry. In this, new computing technology requires users to entrust their valuable data to cloud providers, there have been increasing security and privacy concerns on outsourced data. Several schemes employing attribute-based encryption (ABE) have been proposed for access control of outsourced data in cloud computing. The most[1][2] of them suffer from inflexibility in implementing complex access control policies. In this paper, allowing cloud service providers (CSPs), which are not in the same trusted domains as enterprise users, to take care of confidential data, may raise potential security and privacy issues. To keep the sensitive user data confidential against untrusted CSPs, a Natural way is to apply cryptographic approaches, by disclosing Decryption keys only to authorized users. But also provide full delegation, and scalability, so as to best serve the needs of accessing data anytime and anywhere, delegating within enterprises, and achieving a dynamic set of users. [3][4]HASBE employs multiple value assignments for access expiration time to deal with user revocation more efficiently than existing schemes. It can be providefine-grained access control and full delegation. Finally, we propose a scalable revocation scheme by delegating to the CSP most of the computing tasks in revocation, to achieve a dynamic set of users efficiently.
