An induction-based compaction of sets of association rules among Web concepts

Association rules are nowadays regarded as robust vehicles for creating Web recommendations. We present an induction-based technique for creating a compact representation of sets of association rules, particularly intended for publishing the compact representation in the Web. Our technique efficiently induces a defeasible logic program from a set of association rules, in a manner that the complete set of the given associations can be concluded, when integrating the induced compact program within a defeasible logic reasoning framework.
Performance and Stress Analysis of Metal Oxide Films for CMOS-Integrated Gas Sensors

The integration of gas sensor components into smart phones, tablets and wrist watches will revolutionize the environmental health and safety industry by providing individuals the ability to detect harmful chemicals and pollutants in the environment using always-on hand-held or wearable devices. Metal oxide gas sensors rely on changes in their electrical conductance due to the interaction of the oxide with a surrounding gas. These sensors have been extensively studied in the hopes that they will provide full gas sensing functionality with CMOS integrability. The performance of several metal oxide materials, such as tin oxide (SnO2), zinc oxide (ZnO), indium oxide (In2O3) and indium-tin-oxide (ITO), are studied for the detection of various harmful or toxic cases. Due to the need for these films to be heated to temperatures between 250 °C and 550 °C during operation in order to increase their sensing functionality, a considerable degradation of the film can result. The stress generation during thin film deposition and the thermo-mechanical stress that arises during post-deposition cooling is analyzed through simulations. A tin oxide thin film is deposited using the efficient and economical spray pyrolysis technique, which involves three steps: the atomization of the precursor solution, the transport of the aerosol droplets towards the wafer and the decomposition of the precursor at or near the substrate resulting in film growth. The details of this technique and a simulation methodology are presented. The dependence of the deposition technique on the sensor performance is also discussed.
Prognostic and predictive value of PDL1 expression in breast cancer

Expression of programmed cell death receptor ligand 1 (PDL1) has been scarcely studied in breast cancer. Recently PD1/PDL1-inhibitors have shown promising results in different carcinomas with correlation between PDL1 tumor expression and responses. We retrospectively analyzed PDL1 mRNA expression in 45 breast cancer cell lines and 5,454 breast cancers profiled using DNA microarrays. Compared to normal breast samples, PDL1 expression was upregulated in 20% of clinical samples and 38% of basal tumors. High expression was associated with poor-prognosis features (large tumor size, high grade, ER-negative, PR-negative, ERBB2-positive status, high proliferation, basal and ERBB2-enriched subtypes). PDL1 upregulation was associated with biological signs of strong cytotoxic local immune response. PDL1 upregulation was not associated with survival in the whole population, but was associated with better metastasis-free and overall specific survivals in basal tumors, independently of clinicopathological features. Pathological complete response after neoadjuvant chemotherapy was higher in case of PDL1 upregulation (50% versus 21%). In conclusion, PDL1 upregulation, more frequent in basal breast cancers, was associated with increased T-cell cytotoxic immune response. In this aggressive subtype, upregulation was associated with better survival and response to chemotherapy. Reactivation of dormant tumor-infiltrating lymphocytes by PDL1-inhibitors could represent promising strategy in PDL1-upregulated basal breast cancer.
On Texture and Geometric Feature Based RGB-D Registration

This work addresses the problem of point cloud registration in the context of RGB-Depth data. The Color and Geometric Feature (CGF) registration presented here utilizes both intensity and depth data, in order to achieve an optimal use of all available resources. Registration is achieved by performing optimization over a joint cost function, exploiting texture features and correspondences between planes. For this, a group of planar patches is extracted and matched, with covariances estimated based on the sensor’s error model. Comparisons to other approaches highlight the advantages of CGF registration.
Imaging intraplaque inflammation in carotid atherosclerosis with 11C-PK11195 positron emission tomography/computed tomography.

AIMS We sought to determine whether intraplaque inflammation could be measured with positron emission tomography/computed tomography angiography (PET/CTA) using (11)C-PK11195, a selective ligand of the translocator protein (18 kDa) (TSPO) which is highly expressed by activated macrophages. METHODS AND RESULTS Patients (n = 32; mean age 70 ± 9 years) with carotid stenoses (n = 36; 9 symptomatic and 27 asymptomatic) underwent (11)C-PK11195 PET/CTA imaging. (11)C-PK11195 uptake into carotid plaques was measured using target-to-background ratios (TBR). On CTA images, plaque composition was assessed by measuring CT attenuation of the carotid plaque. Eight patients underwent carotid endarterectomy and ultrathin contiguous sections were processed for TSPO and CD68 (using immunohistochemical staining, (3)H-PK11195 autoradiography, and confocal fluorescence microscopy). Carotid plaques associated with ipsilateral symptoms (stroke or transient ischaemic attack) had higher TBR (1.06 ± 0.20 vs. 0.86 ± 0.11, P = 0.001) and lower CT attenuation [(median, inter-quartile range) 37, 24-40 vs. 71, 56-125 HU, P = 0.01] than those without. On immunohistochemistry and confocal fluorescence microscopy, CD68 and PBR co-localized with (3)H-PK11195 uptake at autoradiography. There was a significant correlation between (11)C-PK11195 TBR and autoradiographic percentage-specific binding (r = 0.77, P = 0.025). Both TBR and CT plaque attenuation had high negative predictive values (91 and 92%, respectively) for detecting symptomatic patients. However, the best positive predictive value (100%) was achieved when TBR and CT attenuation were combined. CONCLUSION Imaging intraplaque inflammation in vivo with (11)C-PK11195 PET/CTA is feasible and can distinguish between recently symptomatic and asymptomatic plaques. Patients with a recent ischaemic event had ipsilateral plaques with lower CT attenuation and increased (11)C-PK11195 uptake.
A Cumulative Authentication Method for Securing Source Routing Protocols in Ad Hoc Networks

Initial works in ad hoc routing have considered only the problem of providing efficient mechanisms for finding paths in such networks, without considering security as a major problem. In such a trusted environment, malicious behaviors can disturb routing process. We present the design and performance evaluation of a new secure on-demand routing protocol for ad hoc networks, called CASR. CASR is robust against attackers from outside of the network and even it prevents compromised nodes from tampering with uncompromised routes consisting of uncompromised nodes. Because of using symmetric cryptography in its structure, CASR is robust against large number of types of denial-of-service attacks. However, due to the applying of the random key predistributions method to the routing process our proposed scheme reaches a trade-off between the degree of security and complexity.
Biocompute 2.0: an improved collaborative workspace for data intensive bio‐science

The explosion of data in the biological community requires scalable and flexible portals for bioinformatics. To help address this need, we proposed characteristics needed for rigorous, reproducible, and collaborative resources for data‐intensive science. Implementing a system with these characteristics exposed challenges in user interface, data distribution, and workflow description/execution. We describe ongoing responses to these and other challenges. Our Data‐Action‐Queue design pattern addresses user interface and system organization concepts. A dynamic data distribution mechanism lays the foundation for the management of persistent datasets. Makeflow facilitates the simple description and execution of complex multi‐part jobs and forms the kernel of a module system powering diverse bioinformatics applications. Our improved web portal, Biocompute 2.0, has been in production use since the summer of 2010. Through it and its predecessor, we have provided over 56 years of CPU time through its five modules—BLAST, SSAHA, SHRIMP, BWA, and SNPEXP—to research groups at three universities. In this paper, we describe the goals and interface to the system, its architecture and performance, and the insights gained in its development. Copyright © 2011 John Wiley & Sons, Ltd.
GA-based attempts to improve the recognition rate and generalization capacity of the nonlinear soft margin support vector machines

The aim of the paper is to report a new method based on genetic computation of designing a nonlinear soft margin SVM yielding to significant improvements in discriminating between two classes. The design of the SVM is performed in a supervised way, in general the samples coming from the classes being nonlinearly separable. The experimental analysis was performed on artificially generated data as well as on Ripley and MONK's datasets reported in the fourth section of the paper. The tests proved real improvements of both the recognition rate and generalization capacities without significantly increasing the computational complexity.
The Fiscal Costs of Financial Instability Revisited

This paper conducts a comprehensive analysis of the fiscal costs of financial instability (defined as major asset price changes and including, as extreme cases, financial crises). The study identifies three channels to fiscal accounts: 1) revenue effects on capital gains, asset turnover and consumption tax, 2) bailout costs as asset price declines undermine balance sheets of companies/banks, and 3) second-round effects from asset prices changes via the real economy and via debt service costs. A panel analysis and case studies show that episodes of financial instability increase the variability of fiscal balances. Moreover, fiscal costs are often very large and much larger than assumed in the literature so far with public debt rising by up to 50% of GDP during such episodes. These fiscal effects can also serve as a, so far under-emphasised, rationale for the deficit and debt targets in the EU? s Maastricht Treaty and Stability and Growth Pact.

A Computer Algorithm for Reconstructing a Scene from Two Satellite Images

A new camera model for transforming object space coordinates into image coordinates as affected by a push-broom sensor traveling in a straight line is described. It is shown that this transformation can be encoded in a 3 × 4 matrix M representing a non-linear Cremona transformation of object space into image space. Significantly, unlike other known models for satellite cameras, M can be estimated without recourse to iterative techniques. Experimental results demonstrate that the proposed model is quite accurate even for push-broom cameras in low-earth orbits (e.g. SPOT and LANDSAT). A 4 × 4 matrix Q, christened hyperbolic essential matrix, that contains the relative camera models in a stereo setting, is derived. The matrix Q is similar in spirit to that derived by Longuet-Higgins [? ]. However, unlike the latter, it represents the non-linear transformation of a point [u1, v1] in the first image to its corresponding hyperbolic epipolar curve in the second image. A linear method for computing Q from image correspondences is described. It is shown that from two images, the camera models and the corresponding 3-D points can be determined only up to an affine transformatin of 3-D object space and this is the best that can be done in the absence of any ground-truth. If 6 or more ground control points, visible in both images, are provided the stereo problem can be solved using only linear techniques.
Issues in Migrating to XML based Content Management for Academic Web Portal

This paper presents an applied research project for content management which aims to the creation of a university web portal using the XML technology. The work has been carried out in order to reorganize the obsolete HTML based web site. The paper objective is to analyse the main issues involved in the migration process from HTML to XML based content management. The basic issues identified, concerning the creation and management of a medium-large size university web site, include homogeneous presentation, orienteering, navigation and search facilities, resource and competence availability necessary for keeping content updated, etc. From the analysis also emerged that only a minor part of the whole site information does not change, such as history or location, while a part may change occasionally, a part regularly like courses, timetables etc., and another part may be newly generated on a week base rate, such as news, events, and seminar announcements. On the basis of this situation a dynamic content management solution has been envisaged to be effective and has been adopted. A number of issues concerning the budget, low in public university, and scale, neither small nor as large as in big companies/universities, determined the choice of the tool for its implementation and deployment. The Apache Cocoon XML open source tool has been selected and its separation of concerns model exploited. Cocoon provides effective support for the external and internal end users' needs: navigating and browsing the content, checking information and publishing in an easy and quick way, controlling access and roles, guaranteeing security, and supporting workflow management. The fundamental separation of the content from its presentation style and from logic is managed by means of contents stored in XML or in a DB and accessed through the Cocoon ESQL logicsheet, and the use of XSL stylesheets for their presentation. This permits to reuse the same content in different contexts filtering out different information, to guarantee style consistency for presentation of similar pages, and to differentiate content presentation in various contexts. The XML technology is used here in order to represent and present information about news, teaching, research and services of the school. In addition, it is used for defining and controlling the site navigation within a menu xml file and to share common contents. The goal is also to optimize the content maintenance process which can guarantee a higher quality and an up to date web site with useful information both for students and staff. The project development is an on going long process which currently consists of the completion of some modules. In particular, the data about courses and curricula have been collected via XSP web pages and stored in a data base in order to make them available also to other existing applications already in use internally within the administration department.
An eigenvalue perturbation result for stability bound with respect to biased structured perturbations

This paper provides an eigenvalue perturbation result and applies it to the estimation of stability margins for uncertain, linear, discrete-time systems. An upper bound on the norm of a real perturbation maintaining the stability of a given asymptotically stable matrix is computed. It is shown that some other existing unstructured bounds are obtained as particular cases of the estimated stability margin. The main example of application of the estimated bound is relative to the case of structured perturbations given by interval matrices whose non null diagonal elements are not centered around zero. A numerical comparison with other stability bounds proposed in the literature is reported
Structural and Transcriptional Analysis of the Self-Incompatibility Locus of Almond Article, publication date, and citation information can be found at www.plantcell.org/cgi/doi/10.1105/tpc.009290.: Identification of a Pollen-Expressed F-Box Gene with Haplotype-Specific Polymorphism

Gametophytic self-incompatibility in Rosaceae, Solanaceae, and Scrophulariaceae is controlled by the S locus, which consists of an S-RNase gene and an unidentified “pollen S” gene. An ∼70-kb segment of the S locus of the rosaceous species almond, the S haplotype–specific region containing the S-RNase gene, was sequenced completely. This region was found to contain two pollen-expressed F-box genes that are likely candidates for pollen S genes. One of them, named SFB (S haplotype–specific F-box protein), was expressed specifically in pollen and showed a high level of S haplotype–specific sequence polymorphism, comparable to that of the S-RNases. The other is unlikely to determine the S specificity of pollen because it showed little allelic sequence polymorphism and was expressed also in pistil. Three other S haplotypes were cloned, and the pollen-expressed genes were physically mapped. In all four cases, SFBs were linked physically to the S-RNase genes and were located at the S haplotype–specific region, where recombination is believed to be suppressed, suggesting that the two genes are inherited as a unit. These features are consistent with the hypothesis that SFB is the pollen S gene. This hypothesis predicts the involvement of the ubiquitin/26S proteasome proteolytic pathway in the RNase-based gametophytic self-incompatibility system.
High quality single crystals of the SrR2O4 family of frustrated magnets

Large high quality single crystals of several compounds of the new family of frustrated magnetic oxides SrR2O4 where R = Dy, Er, Ho and their nonmagnetic analogues with R = Lu, Y have been synthesized by the floating zone technique. The magnetic rare earth ions in these compounds are linked to each other through a network of hexagons and triangles reminiscent of the honeycomb lattice. Initial characterization measurements show that geometrical frustration plays an important role in the formation of the magnetic ground states in these systems. The single crystals grown are suitable for more detailed investigations, especially those using neutron scattering techniques.
Investigation of the Distributions and Types of Multidrug-Resistant Acinetobacter baumannii in Different Departments in a General Hospital

Background: Acinetobacter baumannii is the most prevalent strain in hospitals and different clinical departments. Objectives: The current study aimed to investigate the genetic characteristics and resistance mechanisms of A. baumannii isolated from clinical samples in Shaoxing people’s hospital affiliated to Zhejiang University, Shaoxing, China. Patients and Methods: Acinetobacter baumannii strains were isolated from blood, phlegm and skin of the patients hospitalized in different departments as respiratory medicine, plastic surgery and intensive care unit (ICU). Multilocus sequence typing (MLST) was used to characterize the isolates. Kirby-Bauer test was used to evaluate antibiotic resistance of the bacteria. The expression of resistance inducing genes was detected by reverse transcription polymerase chain reaction (RT-PCR). The results were analyzed and compared. Results: Two bacterial types, ST208, and ST218, were identified in all 140 samples. The ST208 mainly came from ICU and department of respiratory medicine, while ST218 from department of plastic surgery; 70.21% of ST208 and 84.78% of ST218 were carbapenem-resistant Acinetobacter baumannii (CRAB) and carbapenem-susceptible Acinetobacter baumannii (CSAB), respectively. Multidrug-resistance genes in CRAB isolated from the hospital mainly included, oxa-23, oxa-5, intl 1 and qaceΔ1-sul 1. Besides, the highest and lowest antibiotic resistance was observed in the strains isolated from blood samples and wounds, respectively. Conclusions: The distribution of AB varies in different clinical departments and samples. In the hospital under study, the main types of AB were ST208 and ST218. The genes which affect the ability of antibiotic-resistance were oxa-23, oxa-51, intl 1 and qaceΔ1-sul 1.
Vision and Night Driving Abilities of Elderly Drivers

Objective: In this article, we review the impact of vision on older people's night driving abilities. Driving is the preferred and primary mode of transport for older people. It is a complex activity where intact vision is seminal for road safety. Night driving requires mesopic rather than scotopic vision, because there is always some light available when driving at night. Scotopic refers to night vision, photopic refers to vision under well-lit conditions, and mesopic vision is a combination of photopic and scotopic vision in low but not quite dark lighting situations. With increasing age, mesopic vision decreases and glare sensitivity increases, even in the absence of ocular diseases. Because of the increasing number of elderly drivers, more drivers are affected by night vision difficulties. Vision tests, which accurately predict night driving ability, are therefore of great interest. Methods: We reviewed existing literature on age-related influences on vision and vision tests that correlate or predict night driving ability. Results: We identified several studies that investigated the relationship between vision tests and night driving. These studies found correlations between impaired mesopic vision or increased glare sensitivity and impaired night driving, but no correlation was found among other tests; for example, useful field of view or visual field. The correlation between photopic visual acuity, the most commonly used test when assessing elderly drivers, and night driving ability has not yet been fully clarified. Conclusions: Photopic visual acuity alone is not a good predictor of night driving ability. Mesopic visual acuity and glare sensitivity seem relevant for night driving. Due to the small number of studies evaluating predictors for night driving ability, further research is needed.

The spaces of Laurent polynomials, Gromov-Witten theory of ℙ1-orbifolds and integrable hierarchies

Abstract Let Mk,m be the space of Laurent polynomials in one variable , where k,m ≧ 1 are fixed integers and . According to B. Dubrovin [B. Dubrovin, Geometry of 2d topological field theories, Integrable systems and quantum groups (Montecatini Terme 1993), Lect. Notes Math. 1620, Springer, Berlin (1996), 120–348. ], Mk,m can be equipped with a semi-simple Frobenius structure. In this paper we prove that the corresponding descendent and ancestor potentials of Mk,m (defined as in [A. Givental, Semisimple Frobenius structures at higher genus, Internat. Math. Res. Notices 23 (2001), 1265–1286. ]) satisfy Hirota Quadratic Equations (HQE for short). Let k,m be the orbifold obtained from ℙ1 by cutting small discs D 1 ≅ {|z| ≦ ε} and D2 ≅ {|z –1| ≦ ε} around z = 0 and z = ∞ and gluing back the orbifolds D 1/ℤ k and D 2//ℤ m in the obvious way. We show that the orbifold quantum cohomology of k,m coincides with Mk,m as Frobenius manifolds. Modulo some yet-to-be-clarified details, this implies that the descendent (respectively the ancestor) potential of Mk,m is a generating function for the descendent (respectively ancestor) orbifold Gromov-Witten invariants of k,m. There is a certain similarity between our HQE and the Lax operators of the extended bi-graded Toda hierarchy, introduced by G. Carlet in [G. Carlet, The extended bigraded Toda hierarchy, J. Phys. A 39 (2006), no. 30, 9411–9435. ]. Therefore, it is plausible that our HQE characterize the tau-functions of this hierarchy and we expect that the extended bi-graded Toda hierarchy governs the Gromov-Witten theory of k,m.
