Wideband multi-layered cylindrical conformal slot antenna

A wide band conformal wide slot antenna on circular cylindrical structure with appropriate feed matching circuit is proposed. The slot antenna is in the shape of a hexagon and is fed capacitively by small parasitic patches. These parasitic patches are fed by a microstrip line. The antenna proposed, with an overall substrate thickness of 1.2mm has at least 62 percent bandwidth over the frequency range of 3.38-6.38GHz. The dependence of design parameters on the bandwidth characteristics is investigated. The simulation via a Finite Difference Time domain method in cylindrical coordinates, and measured results on the return loss and the E and H plane radiation patterns of the proposed antennas are presented and shown to be in good agreement.
Localization in Wireless Sensor Networks with Known Coordinate Database

Geographic location of nodes is very useful for a sensor network. A novel and practical Radio Frequency (RF)-based localization algorithm called Kcdlocation has been presented for some specific sensor network topologies, such as the grid and linear types. The Kcdlocation algorithm is adapted to those wireless sensor networks deployed with known coordinate database. It examines the ordered sequence of neighboring unknown nodes relative to some anchor nodes so that they are ranked to compute the location of unknown nodes by wireless localization measurements. After the task of distinguishing neighboring unknown nodes is completed through the ranging technology, the correct position for each sensor node would be identified. The localization scalability and fault tolerant performance of this algorithm have been evaluated from the perspective of practicability. Its performances for the real circumstance are verified through different experiments with several RF channels and deployment parameters. The node localization accuracy of Kcdlocation in a 5 * 4 grid network reaches 100% in a flat open square.
Randomized Trial of Parent Management Training in Children With Tic Disorders and Disruptive Behavior

Oppositional, defiant, and disruptive behaviors are common in clinical samples of children with tic disorders. In this study, we sought to evaluate the short-term efficacy of a structured parent training program in children with tic disorders accompanied by disruptive behavior. Children with tic disorders and at least a moderate level of disruptive behavior were randomly assigned to a 10-session structured parent management training program or to continue treatment as usual. Twenty-four children (18 boys and 6 girls) between the ages of 6 and 12 years (mean 8.9 ± 2.0 years) were enrolled; 23 subjects completed the study. At baseline, subjects showed moderate to severe levels of oppositional and defiant behavior. Twenty subjects (83%) were on stable medication. The parent-rated Disruptive Behavior Rating Scale score decreased by 51% in the parent management training group compared with a decrease of 19% in the treatment as usual group (P < .05). On the Improvement scale of the Clinical Global Impression, a rater masked to treatment assignment classified 7 of 11 subjects who completed parent management training as much improved or very much improved compared with 2 of 12 subjects in the treatment as usual group (Fisher exact test, P < .05). These results suggest that parent management training is helpful for short-term improvement in disruptive behavior problems in children with tic disorders. Larger randomized clinical trials are needed. (J Child Neurol 2006;21:650—656; DOI 10.2310/ 7010.2006.00159).
Measuring Gas Temperature in Highly Particle Laden Flow Using Terahertz Spectroscopy

We developed two methods to use terahertz (THz) spectroscopy to perform gas temperature measurement: using the area ratio of two H2O vapor absorbance peaks, and using the relative time delay of the THz signal, both of which change as a function of temperature. Both methods can be used in situations with high particle loading that would block traditional laser signals and degrade thermocouple performance, as THz signals do not attenuate due to particle scattering. The absorbance peak ratios were tested in the frequency range of 0.5-0.8 THz at temperatures of 523-773 K. The relationship between the gas temperature and line strength ratio of the peaks match those calculated using the HITRAN database, but has high uncertainty due to THz source instability. The time delay was tested at a frequency of 0.5 THz and temperatures of 293-773 K, and is used to determine temperature by calculating the index of refraction of the gas. It is a more accurate method, but requires knowledge of the gas composition.
An improved variable neighborhood search for the open vehicle routing problem with time windows

This paper considers the open vehicle routing problem with time windows (OVRPTW). An improved variable neighborhood search (VNS) algorithm is proposed to solve the problem. The improved VNS features a route construction mechanism to ensure the customers with earlier time windows will be served first. The results of computational study indicate that the proposed algorithm can solve OVRPTW effectively.
Parallel Interleavers Through Optimized Memory Address Remapping

This work presents mathematical models and collision-free exchange rules for a parallel interleaver, using which it develops an optimized memory address remapping (OPMM) scheme that enables a classic interleaver to be exchanged for a parallel interleaver readily and efficiently. Both analytic and experimental results demonstrate that the rate of annealing achieved using the OPMM approach is much faster than that achieved using the traditional memory address remapping (MM) method.
Continuum-distorted-wave-final-state approximation in positron-hydrogenic atom (ion) collisions with positronium formation.

We study theoretically the formation of positronium atoms through electron capture in collisions of positrons impacting on hydrogenlike targets such as He{sup +}, Li{sup 2+}, and Be{sup 3+}. We obtain the scattering amplitude of the charge-exchange process by using a distorted-wave model derived from the first order of a Dodd and Greider{close_quote}s expansion. We compute differential and total cross sections by using a partial-wave technique. {copyright} {ital 1996 The American Physical Society. }
Real-time face verification using multiple feature combination and a support vector machine supervisor

This paper proposes a novel face verification algorithm based on multiple feature combination and a support vector machine. The main issue in face verification is to deal with the variability in appearance. It seems difficult to solve this issue using a single feature. Therefore, a combination of mutually complementary features is necessary to cope with various changes in appearance. From this point of view, we describe the feature extraction approaches based on multiple principal component analysis and edge distribution. These features are projected on a new intra-person/extra-person similarity space that consists of several simple similarity measures, and are finally evaluated by a support vector machine supervisor. From the experiments on a realistic and large database, an equal error rate of 0.029 is achieved, which is a sufficiently practical level for many real-world applications.
Integrated Regulation of Acetoin Fermentation by Quorum Sensing and pH in Serratia plymuthica RVH1

ABSTRACT During fermentation of sugars, a number of bacterial species are able to switch from mixed acid production to acetoin and 2,3-butanediol production in order to avoid lethal acidification of their environment, although the regulation of this switch is only poorly understood. In this study, we report the identification of the budAB structural operon, involved in acetoin production in Serratia plymuthica RVH1, and its activation by a LysR-type regulator encoded by budR, immediately upstream of this operon. In addition, the regulation of budR transcription was elucidated and found to be subject to negative control by BudR itself and to positive control by external stimuli such as N-(3-oxohexanoyl)-l-homoserine lactone (OHHL) quorum sensing signaling molecules and acetate. Interestingly, however, we observed that induction of budR transcription by OHHL or acetate did not require BudR, indicating the involvement of additional regulatory factors in relaying these environmental signals to the budR promoter.
COMBINING CASE-BASED REASONING AND PLANNING METHODS FOR INTELLIGENT SPARE PARTS PACKAGE PLANNING SUPPORT

VAS 2000 is a project at debis SH for the Part Center of DaimlerChrysler. The Part Center currently stores and handles about 400.000 Mercedes-Benz spare parts. The majority of these parts has to be packed to be protected during storage and transport. The list of activities describing how and by which means the respective part has to be packed is called a packing instruction. Whenever a new car model is introduced or changes in marketing or ecological requirements occur, packing instructions for several thousand parts have to be generated in a short period of time. To define packing instructions manually is not necessarily very efficient and effective in such situations.
Vision in film and special effects

Computer vision techniques have become increasingly important in visual effects. When a digital artist inserts an effect into a live-action scene, the more information that they know about the scene, the better. In visual effects, we use vision techniques to calculate the location of the camera, construct a 3D model of the scene and follow objects as they move through the scene.Think back to the 1980s, before computer graphics in special effects really took hold. In most of the films of that era, it was very easy to spot the "effects shot" in a film. The give-away was the sudden halting of a previously dynamic, moving camera. This was done because inserting a special effect character or object into a scene with a moving camera was very difficult. The camera move used in filming the live action part of the scene must be exactly reproduced by the camera on the effects set when the model or puppet is filmed. To accomplish this, one of two techniques were employed: 1) mechanical devices were used to encode the motion of the camera and then the encoded information was used to control the motion of the camera on the effects set, or 2) an experienced motion control engineer matched the move by eye. Both of these techniques are terribly prone to error and were used only on high budget productions.In the 1990s with the advent of widespread computer generated effects and digital scanning of film, it became possible to apply computer vision techniques to extract information from the scene to aid the digital artist in blending an effect with the reality of the filmed image.
Probabilistic gait modelling and recognition

Biometric researchers have recently found considerable applicability of gait recognition in visual surveillance systems. This study proposes a probabilistic framework for gait modelling that is applied to gait recognition. The basic idea of this framework is to consider the silhouette shape as a multivariate random variable and model it in a full probabilistic framework. The Bernoulli mixture model is employed to model silhouette distribution and recursive algorithms are provided for silhouette image and sequence classification. Finally, the proposed probabilistic method is applied to benchmark databases and its validity is demonstrated through experiments.
Rates of Surgical Care in Prepaid Group Practices and the Independent Setting What Are the Reasons for the Differences?

The Seattle Prepaid Health Care Evaluation Project is a comparative study designed to assess the care received by persons enrolled in either a large prepaid group practice (PGP) or in a prepaid, independent practice setting in which physicians are reimbursed on a fee-for-service basis (IPP). As part of the study we assessed the patterns of surgical care for hysterectomy, cholecystectomy, appendectomy, and tonsillectomy/adenoidectomy. Overall, there were 215 such procedures with an exposure adjusted rate being five times higher in the IPP than in the PGP. After eliminating 43 per cent of procedures in the IPP and 22 per cent in the PGP which did not meet specified criteria for either necessary, appropriate or justifiable surgery, the exposure-adjusted rate differential was 3.9 times higher in the IPP with the difference in the rates being mainly attributable to hysterectomy and tonsillectomy/adenoidectomy.We conclude there were more unnecessary procedures in the IPP, but the fact that a significant difference in the incidence of surgery persisted even after elimination of such cases suggests that the differences in rates of surgery between the IPP and PGP cannot be solely attributed to a higher rate of inappropriate surgery in the IPP.
Toward plagiarism detection using citation networks

Plagiarism makes people lose trust and discourages innovation in the research community. In this paper, we proposed a model for plagiarism using citation networks. More precisely, we used fragments of texts citing a document as surrogates for that document. Furthermore, we applied the model to a plagiarism detection system, and evaluated its effectiveness. Our experiment results suggest that our method may be able to detect plagiarism although the source documents of a plagiarized one are not included in a collection of documents. Moreover, our method improves the existing method when they are combined.
Pharmacist—Pharmacy Technician Intraprofessional Collaboration and Workplace Integration: Implications for Educators

Globally, concerns have been expressed regarding the impact of regulation of pharmacy technicians. After more than a decade of experience with technician regulation in Ontario, Canada, uptake of the full scope of practice for technicians has been sporadic at best. The objective of this study was to examine barriers and facilitators to intraprofessional collaboration between pharmacists and pharmacy technicians for the purpose of identifying possible curricular or educational interventions to enhance workplace integration. A qualitative, interview-based study of 24 pharmacists, technicians, educators, pharmacy managers, and owners was undertaken using a semi-structured interview guide. Key findings of this research include: (i) Confirmation of suboptimal utilization of regulated technicians in practice; (ii) identification of crucial knowledge and skills gaps for both pharmacists and technicians; and (iii) proposals for undergraduate education and training, and continuing professional development learning opportunities to address these gaps. In order to achieve the promise and potential of regulation of pharmacy technicians, system-wide change management—beginning with education—will be required and will benefit from multiple stakeholder engagement and involvement.
A novel reliable routing scheme for Tactile-oriented Internet traffic

Over the past few years, many scientists have envisioned an Internet generation that will not only provide voice and data communications but can also support Haptic communications. This new Internet dimension can be beneficial for the society by facilitating the development of new technologies and applications that will improve our standards of living. In this study, we propose a novel traffic engineering policy that can satisfy the extremely strict requirements of the new traffic class associated with Haptic communications. Our proposed policy is based on Multi-Plane Routing (MPR) that consolidates various aspects in all-IP access infrastructures and enables network-wide path diversity. To this end, MPR has been remodeled and extended to facilitate Haptic communications. Our simulation results demonstrate that our proposed policy outperforms intra-domain routing protocols namely Open Shortest Path First (OSPF) and performs near-optimally. It will also become apparent that shortest-path solutions such as OSPF can not be used in order to handle Haptic communications in typical Internet network topologies. Finally, we formulate a binary optimization problem for the selection of the optimal Routing Plane (RP) in terms of the network effects such as delay, jitter and packet loss.
Symmetry and duality in Lévy markets

The aim of this paper is to introduce the notion of symmetry in a Lévy market. This notion appears as a particular case of a general known relation between prices of put and call options, of both the European and the American type, which is also reviewed in the paper, and that we call put–call duality. Symmetric Lévy markets have the distinctive feature of producing symmetric smile curves, in the log of strike/futures prices. Put–call duality is obtained as a consequence of a change of the risk neutral probability measure through Girsanov's theorem, when considering the discounted and reinvested stock price as the numeraire. Symmetry is defined when a certain law before and after the change of measure through Girsanov's theorem coincides. A parameter characterizing the departure from symmetry is introduced, and a necessary and sufficient condition for symmetry to hold is obtained, in terms of the jump measure of the Lévy process, answering a question raised by Carr and Chesney (American put call symmetry, preprint, 1996). Some empirical evidence is shown, supporting that, in general, markets are not symmetric.
Extracting Personal Medical Events for User Timeline Construction using Minimal Supervision

In this paper, we describe a system for automatic construction of user disease progression timelines from their posts in online support groups using minimal supervision. In recent years, several online support groups have been established which has led to a huge increase in the amount of patient-authored text available. Creating systems which can automatically extract important medical events and create disease progression timelines for users from such text can help in patient health monitoring as well as studying links between medical events and users’ participation in support groups. Prior work in this domain has used manually constructed keyword sets to detect medical events. In this work, our aim is to perform medical event detection using minimal supervision in order to develop a more general timeline construction system. Our system achieves an accuracy of 55.17%, which is 92% of the performance achieved by a supervised baseline system.
Animating cartoon faces by multi‐view drawings

In this paper, we present a novel framework for creating cartoon facial animation from multi‐view hand‐drawn sketches. The input sketches are first employed to construct a base mesh model by using a hybrid sketch‐based method. The model is then deformed for each key viewpoint, yielding a set of models that closely match the corresponding sketches. We introduce a view‐dependent facial expression space defined by the key viewpoints and the basic emotions to generate various facial expressions viewed from arbitrary angles. The output facial animation conforms to the input sketches and maintains frame‐to‐frame correspondence. We demonstrate the potential of our approach through an easy‐to‐use system, where the animating of cartoon faces is automated once the user accomplishes sketching and configuration.

Experimental study of the induced polarization effect using Cole-Cole and GEMTIP models

Modeling induced polarization (IP) phenomena is important for developing effective methods for remote sensing of subsurface geology. Two resistivity relaxation models have been developed to describe the IP effect. The Cole-Cole model was formulated empirically more than 50 years ago. A few of the parameters within this model are able to account for IP phenomena and can give useful information for the analysis of bulk rock formations. Forward modeling using synthetic data is done to analyze the three empirical variables of the Cole-Cole model. These empirical variables are the decay coefficient (C), chargeability (m), and the time constant (τ). The generalized effective-medium theory of induced polarization (GEMTIP) model is another resistivity model similar to the Cole-Cole model. However, the GEMTIP model attempts to characterize heterogeneous, multiphase, polarized media using the effective-medium approach and can consider many more useful parameters than the Cole-Cole model. Forward modeling is also done with synthetic data to analyze four GEMTIP parameters. These parameters are the surface polarizability coefficient (α), the decay coefficient (C), the inclusion volume fraction (f), and the ellipticity of the inclusions ( ). Complex resistivity data was collected on several rock samples that contain disseminated sulfides, which are conducive to IP phenomena. Inversion of these data were done using both the spherical and elliptical GEMTIP models. In addition, complex resistivity data collected from a carbonate and two shale samples containing pyrite were also inverted using both the Cole-Cole and elliptical GEMTIP models in order to compare their effectiveness in recovering IP parameters. In the case of Cole-Cole inversion, the regularized Newton method was used, and in the case of GEMTIP inversion, the regularized conjugate-gradient method was implemented. Several of the parameters considered in this study were directly measured using X-ray microtomography and the QEMSCAN. Some of these parameters were included in the inversion routines to facilitate accurate inversion results. While the exact cause of the IP effect is quite complicated and still not perfectly understood, it is known that being able to model it can be very useful in improving mineral discrimination techniques. With improved understanding of the IP effect and new advancements in rock physics models, mineral discrimination will become more effective as well as more reliable.
Tumourigenicity of MTG8, a leukaemia‐related gene, in concert with v‐Ha‐ras gene in BALB/3T3 cells

The MTG8 (ETO) gene has been identified as the translocation partner of AML1 (PEBP2αB or CBFα2) gene in the AML1/MTG8 (ETO) fused gene caused by t(8;21) translocation in human acute myeloid leukaemia, M2 type. Although AML1/MTG8 chimaeric protein is known to inhibit the functioning of AML1 protein, the precise function of MTG8 gene itself is not known yet. We studied the significance of MTG8 gene in the oncogenicity of AML1/MTG8 fused gene, by introducing full‐length MTG8 cDNA into both BALB/3T3 cells containing v‐Ha‐ras gene (Bhas 42 cells) and BALB/3T3 cells without v‐Ha‐ras gene.
Brevundimonas mediterranea sp. nov., a non-stalked species from the Mediterranean Sea.

Six strains of Gram-negative, rod-shaped, non-spore-forming bacteria were isolated from the Mediterranean Sea. 16S rRNA gene sequence analysis indicated that the strains were affiliated within the alphaproteobacterial genus Brevundimonas, with Brevundimonas intermedia (99.4 %) and Brevundimonas vesicularis (99.2 %) as their closest relatives. This affiliation was supported by chemotaxonomic data (major polar lipids: phosphatidyl diacylglycerol, sulfoquinovosyl diacylglycerol and phosphatidyl glucopyranosyl diacylglycerol; major fatty acids: C(18 : 1), C(16 : 0), C(16 : 1), C(15 : 0), C(17 : 1)omega8c, 11-Me-C(18 : 1)omega5t). The results of DNA-DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of the strains from all recognized Brevundimonas species. The strains therefore represent a novel species, for which the name Brevundimonas mediterranea sp. nov. is proposed, with the type strain V4.BO. 10T)(=LMG 21911T=CIP 107934T).
