A Framework to Support Non-fragile Agile Agent-Oriented Software Development

Agile software development methods support mainly object-oriented, feature-oriented and component-oriented software development and do not address agent-oriented and aspect-oriented software development. The concepts of agents and objects are in many ways dissimilar; and an object-oriented approach is not immediately suitable for the development of a multiagent system. In our current research, we extend agile software development methods originating primarily in object-oriented technology to support agent-orientation in the context of the development of multiagent systems. This research paper introduces a new agile agent-oriented framework to create or tailor situation-specific non-fragile agile agent-oriented software development processes (using a method engineering approach) to support multi-agent software development.
Transmission-line metamaterial antennas for THz quantum-cascade lasers

We present a scheme for achieving active composite right/left handed (CRLH) transmission line metamaterial waveguides in the THz by loading THz QC-laser metal-metal waveguides with sub-wavelength capacitive and inductive structures. We discuss our progress in using transmission-line metamaterial concepts for the engineering of THz active leaky-wave antennas that provide amplification and exhibit beam steering.
Evaluation of ex vivo effectiveness of commercial desensitizing dentifrices

Background Dentin hypersensitivity is a short, severe pain with fast onset. Therapy aims to either prevent or decrease neural transmission or physically occlude the dentinal tubules. This study aimed to evaluate the effectiveness of commercial desensitizing dentifrice by means of an ex vivo method. Material and Methods Samples (n=8 lower human premolars for each group) were randomly allocated into: G1- brushing with Colgate®Sensitive Pro-Relief; G2- brushing with Sensodyne®Rapid Relief; G3- brushing with Sensodyne®Repair & Protect; and G4- brushing with Colgate®Maximum Cavity Protection. The test bodies were submitted to simulated toothbrushing and dentifrices were analyzed regarding their hydrodynamic size, polydispersity index (PI) and zeta potential. Specimens were evaluated using: scanning electron microscopy (SEM); spectroscopy energy dispersive X-ray (EDS); and profilometry. A qualitative analysis of the photomicrographs and topographies was performed. Results The dentifrices showed statistical similar physical and chemical characteristics. They also demonstrated obliteration of dentinal tubules when micrographs were observed. Regarding the chemical elements present in the dentin samples, there was a statistically significant difference between the control and experimental surfaces in the four groups. Conclusions Joint data analysis shows that the desensitizing dentifrice showed better results with regards to the obliteration of dentinal tubules compared to positive and negative controls. Key words:Dentin hypersensitivity, dentin desensitizing agents, toothpastes.
A Review on Thermal Spray Coating Processes

Surface coating is an economic method for the production of materials, tools and machine parts that require the desired surface properties such as corrosion, erosion and wear resistance. Different coatings are used to achieve the desired properties. Thermal spray coating is one of the most effective methods to protect the new parts from wear, high temperature corrosion, residual stresses, erosion, and to provide hard and dense coatings, thus life of material is increased. In this paper an attempt has been made to focus on Plasma Spray, Electric Arc Wire Spray Flame Spray, High Velocity Oxy-Fuel Spray (HVOF) techniques their basic principles, benefits, application, comparison.
The Complications of Age-Related Macular Degeneration Prevention Trial (CAPT): rationale, design and methodology

Background The Complications of Age-Related Macular Degeneration Prevention Trial (CAPT) is a randomized clinical trial to evaluate whether prophylactic laser treatment to the retina can prevent the complications of the advanced stage of Age-Related Macular Degeneration (AMD), the leading cause of irreversible blindness. Methods CAPT is conducted in 23 clinical centers and in three central resource centers. The primary outcome measure is change in visual acuity; secondary outcomes include the incidence of complications of AMD, changes in other measures of visual functioning and vision-related quality of life. In total, 1052 patients with two high-risk eyes were enrolled. One eye was randomized to receive laser treatment and the other eye to observation. All patients were treated immediately after randomization and again at 12 months, dependent on clinical status. All patients are followed via study visits and telephone calls for a minimum of five years. Study visit procedures include established tests of visual function conducted by examiners masked to the treatment assignment of each eye, a biomicroscopic examination by CAPTophthalmologists, and photographs of each eye taken according to protocol and assessed by masked graders in a centralized Photograph Reading Center. Results This paper describes the CAPT study, including study rationale, operational structure, and measures implemented to ensure standardization of assessments, adherence to protocol, quality assurance, and maintaining follow-up. Several features related to study design and procedures that are specific to CAPT are highlighted, including clinic selection and judgements regarding patient eligibility. Conclusions An intervention that can reduce the risk of advanced AMD by 30% in the eyes of people with two high-risk eyes may halve the rate of bilateral blindness from AMD. It would also yield substantial savings in expenditures devoted to treating advanced AMD and the disability it causes, and enhance the quality of life for people at risk.

Bridging science and practice in child welfare and children’s mental health service systems through a two-decade research center trajectory

• Summary: Over the past two decades, research on social work practice has experienced substantial growth in the United States, indicated by both the establishment of the Society for Social Work Research in 1994 and increased funding from the National Institutes of Health (NIH). Recently, this growth has carried an increasing emphasis on research to establish the evidence base for social work practice and an emphasis on understanding dissemination and implementation of evidence-based interventions or practice models in usual care settings within service systems that have historic and professional linkages to the social work discipline, such as child welfare and mental health. • Findings: This article illustrates this growth and emphases on evidence-based practice in the social work research areas, child abuse and neglect, child welfare and child mental health through the two-decade experience of a large-scale and multi-disciplinary research center in San Diego County, California, the Child and Adolescent Services Research Center (CASRC). Evidence for understanding and improving care in these two service systems served by social work practice has been developed through center studies of clinical epidemiology, mental health services, effectiveness of evidence-based interventions, and the dissemination and implementation of these interventions in usual care settings. • Applications: This evolving research agenda was shown to be well linked to the NIH Roadmap initiative and highly competitive for NIH funding.
Interactive Visual Analysis on Large Attributed Networks

Increasing scale leaves a challenging problem for visualizing large attributed networks. Hierarchical aggregation is a promising solution. Existing methods mainly focus on the topological structure but ignore vertex properties; moreover, the inherent hierarchy restricts network navigation process. This paper proposes an user-specified visualization method with a content-based clustering algorithm to explore large attributed networks. The content-based algorithm is able to locate major structures and cluster network based on structural and attribute similarities. Then a novel visualization system is introduced that allows navigation of large networks at any level-of-detail. The user-specified interaction strategy enables user to manipulate cluster metrics and built hierarchy based on interest. Case study demonstrates that the proposed method is effective to extract global knowledge about the network as well as locate critical nodes and major structures.
Asking a Great Question: A Librarian Teaches Questioning Skills to First-Year Medical Students

In a single one-hour session, first-year medical students were taught a framework for differentiating between lower-order questions that lead to knowledge of facts and higher-order questions that lead to integration of concepts and deeper learning, thereby preparing them for problem-based learning (PBL). Students generated lists of questions in response to an assertion prompt and categorized them according to Bloom's Taxonomy. These data were analyzed in addition to data from the course exam, which asked them to formulate a higher-level question in response to a prompt. Categorizing questions according to Bloom's Taxonomy was a more difficult task for students than was formulating higher-order questions. Students reported that the skills that they learned were used in subsequent PBL sessions to formulate higher-order learning objectives that integrated new and previously-learned concepts.

As 3D interfaces, and in particular virtual environments, become increasingly realistic there is a need to investigate the location and configuration of information resources, as distributed in the humancomputer system, to support any required activities. It is important for the designer of 3D interfaces to be aware of information resource availability and distribution when considering issues such as cognitive load on the user. This paper explores how a model of distributed resources can support the design of alternative aids to virtual environment wayfinding with varying levels of cognitive load. The wayfinding aids have been implemented and evaluated in a desktop virtual environment.

THE VECTOR VORTEX CORONAGRAPH: LABORATORY RESULTS AND FIRST LIGHT AT PALOMAR OBSERVATORY

High-contrast coronagraphy will be needed to image and characterize faint extrasolar planetary systems. Coronagraphy is a rapidly evolving field, and many enhanced alternatives to the classical Lyot coronagraph have been proposed in the past 10 years. Here, we discuss the operation of the vector vortex coronagraph, which is one of the most efficient possible coronagraphs. We first present recent laboratory results and then first light observations at the Palomar observatory. Our near-infrared H-band (centered at ∼1.65 μm) and K-band (centered at ∼2.2 μm) vector vortex devices demonstrated excellent contrast results in the lab, down to ∼10−6 at an angular separation of ∼3λ/d. On sky, we detected a brown dwarf companion 3000 times fainter than its host star (HR 7672) in the Ks band (centered at ∼2.15 μm), at an angular separation of ∼2. 5λ/d. Current and next-generation high-contrast instruments can directly benefit from the demonstrated capabilities of such a vector vortex: simplicity, small inner working angle, high optical throughput (>90%), and maximal off-axis discovery space.
Mini-Review Fly Division

S Tumps in animal cells (reviewed by Rappaport, 1986; Satterwhite and Pollard, 1992; Fishkind and Wang, 1995) provide a view of cytokinesis whereby in each dividing cell, a contractile ring of interdigitated anti-parallel actin and bipolar myosin (nonmuscle myosin II) filaments forms in the equatorial region of the cell cortex, and then constricts, in purse string-like fashion, to pinch the cell in two. A number of key questions about this process remain unresolved. An understanding of the signal(s? ) that spatially and temporally orchestrate ring formation is lacking. A comprehensive catalog of the proteins that act in concert with actin and myosin to form the ring is also not yet available. In addition, our knowledge of how the ring is integrated into the cortex at large and is associated with the plasma membrane is only rudimentary. Finally, molecular mechanisms by which each protein contributes to the assembly of the complex, supramolecular structure of the ring and functions in chemomechanical force production are far from clear. The multidisciplinary approaches that are being applied in Drosophila are likely to provide insight into the many aspects of furrow function that remain poorly understood. Recently, genetic approaches have identified several new proteins that are required for cytokinesis and cell biological and biochemical methods have revealed proteins that localize in cytokinetic structures. Together, these findings have expanded the list of the molecules implicated in cytokinesis and are harbingers of a new understanding of cytokinesis at the molecular level.
Economic Impact of Pulmonary Drugs on Direct Costs of Stable Chronic Obstructive Pulmonary Disease

Question of the Study. To assess the impact of prescribing pulmonary drugs according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines on direct costs in stable chronic obstructive pulmonary disease (COPD). Patients and Methods. A total of 560 ambulatory COPD patients completed a specific questionnaire that included data regarding drug therapy. Severity was graded according to the British Thoracic Society (BTS) criteria and appropriateness of pharmacological treatment according to GOLD guidelines. Results. Annual direct costs were 1,657 EUR in stage I, 2,425 EUR in stage II, and 3,303 EUR in stage III. The mean direct costs was 2,061 EUR (38% corresponded to drug therapy). Medication accounted for 43%, 37.6%, and 28.4% of total direct costs for stage I, II, and III, respectively. Inhaled steroids and long‐acting β2‐agonists accounted for 78%, 76%, and 75% of total drugs costs in stages I, II, and III, respectively. Drug therapy which was not in accordance with guidelines accounted for 78.7% and 54% of total drug costs in stages I and II, respectively. Most patients with severe disease were treated adequately. Answer to the Question. Pharmacologic treatment has a great impact on direct medical costs in stable COPD. According to GOLD guidelines, patients with mild or moderate COPD are frequently treated with nonrecommended drugs.
Turnover of nuclear and cytoplasmic ribonucleic acid in two types of animal cell, with some further observations on the nucleolus.

In a previous paper (Watts & Harris, 1959) some of the principles underlying the measurement of nucleic acid turnover in animal cells were discussed. It was shown that although in the macrophage a rapid turnover of ribonucleic acid occurs, as measured by the incorporation and release of [8-14C]adenine, the products of turnover are completely re-utilized by the cell in the resynthesis of ribonucleic acid and are thus continuously recycled. Under such conditions the turnover is not detected unless the cells are cultivated in a medium containing some unlabelled compound which has access to the turnover pathway and dilutes or displaces some labelled intermediate in the process of recycling. Of the compounds tested, adenosine was found to be the most effective in this respect. Measurements of ribonucleic acid turnover in different parts of the cell have been undertaken. These measurements were made possible by the use of tritium-labelled precursors and quantitative radioautographic methods. Two cell types were studied: the connective-tissue cell derived from rat-heart tissue, and the macrophage obtained from the peritoneal cavity of the, rabbit. The former multiplies in vitro; the latter does not multiply but remains alive for long periods. In a previous paper (Harris, 1959) some observations were made on the function of the nucleoli, which are prominent structures in the connectivetissue cell. These observations are further elaborated in the present paper.
Crash prediction and suspicious component determination for proactive recovery management in clustered web applications

The growing complexity of software systems is resulting in an increasing number of software faults. According to the literature, software faults are becoming one of the main sources of unplanned system outages, and have an important impact over company benefits and image. For this reason, a lot of techniques (such as clustering, failover techniques, or server redundancy) have been proposed to avoiding software failures, however they still happen. They can be divided in three categories: permanent, intermittent and transient failures. The first type are easy to fix, but the other two categories are difficult to reproduce and fix, and become a real problem for developers and system administrators. Here we propose a new framework for predicting in real time the time until crash of a clustered application, using machine learning techniques. Our framework allows recovery of the potentially crashing server using a clean automatic recovery and avoiding losses of new or on-going user requests. Furthermore, our framework offers a valuable feedback to the developers by assigning suspicion levels (of provoking the crash) to every component of the application. We have tested our framework in a three-tier web J2EE clustered application achieving promising results.
The ability of parents to accurately report concussion occurrence in their bantam-aged minor hockey league children.

OBJECTIVE The objective of this study was to assess the ability of hockey parents/guardians to recognize concussion symptoms in their 13-14 year old (Bantam-aged) children. OUTCOME MEASURES The outcome measures were the ability to recognize different signs and symptoms listed on the Sport Concussion Assessment Tool (SCAT) as well as 8 detractors consisting of signs and symptoms not associated with post concussive syndrome. Additional questions assessing the parents' knowledge of concussion management and recognition abilities were also posed. PARTICIPANTS Parents of Bantam-aged minor hockey league athletes volunteered for the study. METHODS The study investigators distributed questionnaires during the warm up period or following their children's games to the study participants. Following questionnaire completion, participants were provided with an information package outlining the correct signs and symptoms of concussion. RESULTS The mean number of correct responses to signs and symptoms of concussion was 21.25/25 for the mothers and 20.41/25 for the fathers. The mean number of detractors identified as not associated with concussion was 5.93/8 for the mothers and 4.85/8 for the fathers, indicating that mothers were more capable of recognizing the signs and symptoms than fathers. An analysis of variance including sporting experience in the model did not strengthen the relationship between parent gender and test outcome. CONCLUSION This investigation revealed that there is still a disconnect in regards to key components of recognizing a concussion, such as difficulty with sleep, disorientation symptoms, and emotional irritability. Mothers have displayed an ability to better differentiate between true and false signs and symptoms of concussion as compared to fathers. Continued education and awareness of mild traumatic brain injury in athletes should address the misconceptions amongst parents in regards to the true signs and symptoms of a concussion.
Multi-antenna techniques and beamforming for communication systems

Reconfigurability, efficiency, and power consumption are key areas for improvement in future communication systems. The frequency spectrum is becoming more crowded and the spatial density of users is increasing. It becomes interesting for a communication system to use temporary freedom in the spatial and spectral domain. In this paper, we provide an overview of multi-antenna techniques, which can exploit the spatial degree of freedom, thereby addressing the challenges of flexibility and reconfigurability of front-ends in communication systems. Starting with a general qualification of multi-antenna techniques, their benefits and their goals, we will focus on beamsteering and beamforming techniques and their possible application for communication systems.
2nd European Consensus Meeting on Foam Sclerotherapy 2006, Tegernsee, Germany.

RATIONALE The spread of Foam Sclerotherapy has resulted in the renaissance of sclerotherapy as a non-invasive treatment method for varicosis. The use of sclerosant foam for various forms of varicosis has now become established world-wide as safe and effective. An expanded European expert committee meeting in April 2006, in Tegernsee was prompted by new findings and continuous further development of the method, but also because it had not been possible to consider all the relevant aspects of Foam Sclerotherapy in depth at the first meeting. OBJECTIVES To revise and update the results of the 1st European Consensus Meeting and to include new, important topics in the development of Foam Sclerotherapy. To provide practical information for less experienced colleagues. METHODOLOGY The 29 participants were sent a comprehensive questionnaire in advance covering all the relevant aspects of Foam Sclerotherapy. The organisers drew up various preliminary statements on the basis of the results. During the meeting itself the participants revised and/or approved and/or rejected these statements. An additional analysis of the questionnaire data also enabled preparation of an illustrative description of the broad spectrum of individual procedures used in this form of treatment. RESULTS Foam Sclerotherapy has become an established treatment option for varicosis and has undoubtedly improved the management of varicose veins. European experts met Tegernsee for a second time to revise and expand their previous recommendations. In addition, individual working groups focused extensively on important issues. The current consensus, recommendations and descriptions of the individual aspects of the methods concern such issues as the indications for Foam Sclerotherapy, concentration and volume of the liquid sclerosants, relative and absolute contraindications, access and puncture options as well as clinical and ultrasound-guided recording of the treatment results. This final document reflects the experts' opinions on the principles of the effective and, above all, safe use of sclerosant foam for various indications and correct monitoring of the results of Foam Sclerotherapy.
