Improvement of the radiation and impedance performance for the dielectric rod antenna

The far field radiations by different parts of a dielectric rod antenna are analyzed by decomposing the near fields. A transition section is introduced to improve the radiation performance and impedance matching between the waveguide and the dielectric rod. The results show that using the transition, the backward radiation can be significantly reduced, and the gain can be increased. In addition, the impedance matching performance can be improved in a wide frequency band.
Event-Related Potentials and Picture-Word Naming: Effects of Attention and Semantic Relation for Children and Adults

Event-related potentials (ERPs) were recorded from children, 9 to 13 years of age, while they named words and pictures. The words and pictures were presented individually and in superimposed picture-word pairs in which the meaning of the words and pictures was either congruent, semantically associated, or incongruent. Both words and pictures elicited large amplitude negative waves (N450) at anterior electrode sites. The amplitude of this N450 wave was larger for individually presented pictures than for words. N450 amplitude was also larger when naming pictures than when naming words in the superimposed arrays, an effect that is attributed to differences in attentional demand required to name pictures rather than to exogenous stimulus characteristics. No significant effects of semantic incongruity were observed. These ERP waveforms for children differ from those observed for adults who exhibited positive amplitude waves to individually presented pictures and who also exhibited semantic incongruity effects.
Concentration effect on optical amplification characteristics of Er-doped silica single-mode fibers

Optical amplification characteristics for Er-doped silica core single-mode fiber amplifiers with different Er concentrations pumped by 1.48- mu m-wavelength laser diodes are studied. Optical gain drastically depends on Er concentration, even when the Er concentration is less than 1000 p.p.m. In the case of the 40-mW incident pump power, the maximum net gain for the fiber containing 77 p.p.m. Er is higher than that for the fiber containing 970 p.p.m. Er by 11.4 dB. <<ETX>>
A strategy for obstacle avoidance and its application to mullti-robot systems

We present a local method for obstacle avoidance based on the existence of extreme separating hyperplanes. Its application is then extended to the coordinated motion of several mobile robots, and to the avoidance of two manipulators. The techniques of local planning we develop here prove to be an interesting substitute to the potential field method, as they provide a simple geometric support for the analysis.
Tracking multi-objects using combination feature and Mean Shift

This paper proposes a novel framework for tracking multiple targets with occlusion and illumination changing in scenes. Under our framework, the extension of Mean Shift algorithm via five global and local features: central location, width, height, area and Harris corner information, and Mean Shift (CFMS) are used to track multiple targets. To effectively track multiple objects with occluded and don't split up the object to different part, Harris corner information as local feature is extracted by proposed double threshold Harris corner detection algorithm when there exist occluding, moreover classify the corners in the occluding region by K-NN classifier. The proposed CFMS algorithm achieved tracking of multiple targets based on feature fusion and mean shift algorithm. The experimental results have showed that the proposed method of CFMS can track multiple objects more robustly.
Advances and disputes of posterior malleolus fracture

Objective The objective of this article is to summarize the development of evaluation and treatment of posterior malleolus fracture (PMF). Data sources Data used in this review were mainly from English literature of PubMed data base. Study selection Articles were included in this review if they were related to the PMF or trimalleolar fracture. Results No consensus was found regarding what sizes of posterior malleolus fragments would lead to ankle instability thus affecting prognosis and should be fixed. X‐ray measurement is unreliable, while CT scan is widely recommended and it can recognize the occult posterior malleolus fractures associated with tibia shaft fractures, which are always undetected previously. Direct posterior malleolus fixation is suitable to stabilize syndesmotic injury. The basic and clinical researches support direct reduction and buttress plate fixation of posterior malleolus fracture through the posterolateral approach. Operative indications and timing of weight bearing are still in discussion. Conclusions Knowing whether ankle instability occurs and the proper methods to diagnose, evaluate, and operate can help manage the fracture. Further biomechanical research on ankle stability and clinical study to compare various treatment methods are required.
On the Design and Exploitation of User's Personal and Public Information for Semantic Personal Digital Photograph Annotation

Automating the process of semantic annotation of digital personal photographs is a crucial step towards efficient and effective management of this increasingly high volume of content. However, this is still a highly challenging task for the research community. This paper proposes a novel solution. Our solution integrates all contextual information available to and from the users, such as their daily emails, schedules, chat archives, web browsing histories, documents, online news, Wikipedia data, and so forth. We then analyze this information and extract important semantic terms, using them as semantic keyword suggestions for their photos. Those keywords are in the form of named entities, such as names of people, organizations, locations, and date/time as well as high frequency terms. Experiments conducted with 10 subjects and a total of 313 photos proved that our proposed approach can significantly help users with the annotation process. We achieved a 33% gain in annotation time as compared to manual annotation. We also obtained very positive results in the accuracy rate of our suggested keywords.
[The pharmacological treatment of bipolar disorder: a systematic and critical review of the methodological aspects of modern clinical trials].

OBJECTIVE To review systematically the main clinical trials on the pharmacological treatment of bipolar disorder and to make a critical analysis of their methodological aspects. METHOD A search in Medline, ISI and PsycINFO databases was conducted, using the following search terms: "bipolar", "randomized", "placebo" e "controlled". Randomized, double-blind, placebo-controlled clinical trials on the pharmacological treatment of bipolar disorder were selected. Besides, according to our criteria, samples had to consist of at least 100 patients and experimental drug had to be used as monotherapy. RESULTS 34 articles met our selection criteria. All drugs currently indicated for mania, bipolar depression and maintenance treatment of bipolar disorder were more effective than placebo in at least one clinical trial. However, these studies had highly selected samples, high dropout rates and low response rates. CONCLUSION Modern clinical trials on pharmacological treatment of bipolar disorder have important methodological limitations. So, their results should be taken with caution.
Research on evaluation of enterprise knowledge capability based on grey and fuzzy evaluation

There are issues preventing effective assessment of an enterprise's knowledge capability. To resolve them, the nature of enterprise knowledge capability was analyzed and the standard evaluation index system was designed. Grey and fuzzy assessment for evaluating enterprise knowledge capability was established and it was verified by an empirical case. Three main assessment dimensions were proposed, namely fundamental resource capability, operating knowledge capability and knowledge mechanism. An evaluation system involving 14 indexes was designed. These were the foundations for the evaluation model based on grey and fuzzy evaluation model. Grey and fuzzy evaluation model can not only determine the comprehensive level of enterprise's knowledge capability, but also show advantage and difference of enterprise's knowledge capability from different dimension.
Allergic contact dermatitis: a case series and review for the ophthalmologist

Eyelid dermatitis is most commonly caused by an allergenic response, potentially from exposure at another site, rather than from local toxicity. Yet allergic contact dermatitis is a diagnosis often missed by ophthalmologists. The authors review the literature and detail their experience relating to the causes, clinical features and management of this condition. 14 patients over a 2-year period that were referred to the oculoplastic service for a further opinion were reviewed in a retrospective, non-comparative study. All patients underwent patch testing for diagnosis. 8 of the 14 patients had delays of more than 6 months from symptoms to diagnosis. In six of these, this was greater than 1 year. Similar delays are reported in the literature. 79% of the cases were referred by ophthalmologists. Although two of the patients were biopsied, this did not help in making the diagnosis. 13 patients had disease restricted to the eyelids, though only five of these had direct contact of the allergen with the eyelids. Two patients were also sensitised to topical steroid creams prescribed for their treatment. All patients improved after removal of the allergen. Further clinical features and management options from the literature are reviewed and discussed.
Resonant tunneling in an interacting one-dimensional electron gas.

We study the resonant tunneling of a single-channel interacting electron gas through a double-barrier structure. In striking contrast to the noninteracting electron gas, which exhibits resonances with a temperature-independent Lorentzian line shape at low T, we find that with repulsive interactions present the resonances have a width which vanishes as T→0. Moreover, at low T the resonance line shapes are determined by a universal scaling function, with power law but non-Lorentzian tails. These predictions should be accessible to experiments in single-channel wires in gated GaAs
H2-M3 presents a nonformylated viral epitope to CTLs generated in vitro.

Most CTL responses to epitopes from influenza virus are restricted by MHC class Ia molecules. However, a synthetic peptide corresponding to residues 173 to 190 of influenza A/JAP/305/57 hemagglutinin (HA) can induce, in vitro, a CTL response to peptide presented by a mouse class Ib molecule encoded by a gene telomeric to H2-Q. Here, we identify the molecule as H2-M3 and show that the last five residues of HA173-190, MLIIW, is the minimal epitope for CTL recognition. Cells that express M3wt, from C57BL/6 or BALB/c mice, are sensitized by both MLIIW and the longer peptide HA173-190, whereas cells that express M3f, from A.CA or B10.M mice, are sensitized only by MLIIW; a single amino acid change at residue 31 (V-->M) of M3 accounts for this difference. Although M3-restricted CTLs preferably recognize N-formylated epitopes, i.e., those of mitochondrial or prokaryotic origin, our findings show that M3-restricted primary CTL responses can be generated in vitro against nonformylated epitopes.
An ultrashort pulse radar sensor for vehicular precollision obstacle detection

An ultrashort pulse radar sensor was designed, developed, and fabricated for an automotive hazard evaluation program. Tests verified that this unique system, which had a pulse duration of approximately 1 ns, did meet its design goals. Reflectivity characteristics of several road surfaces and RF scattering cross sections of selected highway objects were measured. Experiments verified the capability of the system to identify one object from another, even for a multiple object environment. An analytical model was developed that describes the Fresnel region scattering characteristics of simple objects.
Ontologies as bridges between data sources and user queries: the KNOWMAK project experience

This paper describes ongoing work in the KNOWMAK project, which aims to develop a webbased tool providing interactive visualisations and state-of-the-art indicators on knowledge cocreation in the European research area. One of the main novel developments in this work is the use of ontologies to act as a bridge between the data sources (research projects, patents and publications) and user queries, in order to address the problems of mapping between heterogenous data sources with different vocabularies while still maintaining a level of standardization necessary for summarising the information required to provide informative views about the highly dynamic S&T landscape.
What Do Gay Men Know About Human Papillomavirus? Australian Gay Men's Knowledge and Experience of Anal Cancer Screening and Human Papillomavirus

Objective: The objective of this study was to determine levels of experience and knowledge concerning anal dysplasia, anal Pap smear tests, and human papillomavirus (HPV) among gay and other homosexually active men. Study Design: Three hundred eighty-four men attending a large gay community event in Melbourne completed a short survey. Results: Ninety-two percent identified as gay and 4.8% as bisexual. A total of 6.4% were HIV-positive and a further 3.5% did not know their HIV status. On a range of measures, it was clear that the men knew very little about anal cancer (19% scored zero on a 12-point knowledge scale) and virtually nothing about HPV (47% scored zero on an 8-point knowledge scale). A total of 55.1% had never heard of an anal Pap smear and 44.8% had ever heard of HPV; 56.4% did not know whether it affected men and/or women. Conclusions: The test for anal dysplasia is still largely unknown among Australian gay men and they currently have poor sense of personal susceptibility to the disease. Health education strategies are suggested to improve this situation.
Resolution of the ocean wave propagation direction in SAR imagery

There is an inherent 180 degrees ambiguity in the derived wave propagation direction when using conventional spectral analysis techniques on standard synthetic aperture radar (SAR) image products. Three different techniques are successfully used to resolve this ambiguity in propagation direction using a single pass of airborne SAR data. The fact that the SAR is characterized by a large time-bandwidth product is used to advantage. A sequence of individual looks extracted from the Doppler spectrum represents images of the scene collected at a sequence of discretely delayed intervals of time. The techniques utilized include cross-correlation-based motion analysis of a pair of looks, phase weighting based upon a pair of looks and the ocean wave dispersion relation, and a three-dimensional spectral analysis. The phase weighting technique is also demonstrated for a Seasat SAR scene. >
CDMA Voice Capacity with Adaptive Equalizer Receivers

We study the Erlang voice capacity of CDMA forward links with least squares adaptive equalizers. The effects of equalizer misadjustment due to limited training samples are accounted for through an accurate, analytical approximation to the equalizer's output SINR probability distribution function. Our results show that a practical least squares adaptive equalizer potentially improves voice capacity by 30-40% over a conventional maximal-ratio combiner RAKE receiver
Mercury Toxicity in Hormonal Effects to Fresh Water Fish Cirrhinus Mrigala

Mercury interfere with a number of processes, regulated by the thyroid hormones T3 and T4 including blood vessel dilation, neurotransmission and immune function.Mercury chloride exposure toxic to the kidney, stomach, and intestines and lead increased blood pressure. Mercury chloride is the chemical compound of mercury and chlorine with the formula HgCl2. Mercuric salts generally target the gastrointestinal tract extensive precipitation of enterocytes protein occurs, with abdominal pain, vomiting and bleed diarrhea with potential necrosis of the gut mucosa. This may produce death either from peritonitis or from septic hypovolemic shock. Surviving patients commonly develop renal tubular necrosis with anuria. Brain dysfunction also occurs due to exposure of mercury. Plasma triiodothyronine (T3) of fish Cirrhinusmrigala exposed to sub lethal concentrations of mercury was presented in Table 2. The plasma triiodothyronine (T3) levels was decreased as the exposure period extended showing a percent decrease of-46.66, -53.84, -10.00, -64.28, -66.66 at the end of 7, 14, 21th, 28, and 35 day, respectively. Table 3 gives data on change in the plasma thyroxin (T4) level of fish Cirrhinusmrigala exposed to sub lethal concentration of mercury. T4 level was also decreased throughout the treatment period showing a percent decrease of -72.29, -73.10, -76.02, -79.86, -79.02 at the end of 7th, 14 , 21, 28, and 35, days respectively.
Productivity of Information Systems in the Healthcare Industry

This research paper analyzes the impact of information technology (IT)in a healthcare setting using a longitudinal sample of hospital data from 1976 to 1994. We classify production inputs into labor and capital categories. Capital is classified into three components--medical IT capital, medical capital, and IT capital--and labor is classified into two components, medical labor and IT labor. Results provide evidence that IT contributes positively to the production of services in the healthcare industry.
A direct approach to solving trajectory planning problems using genetic algorithms with dynamics considerations in complex environments

SUMMARY This paper presents a new genetic algorithm methodology to solve the trajectory planning problem. This methodology can obtain smooth trajectories for industrial robots in complex environments using a direct method. The algorithm simultaneously creates a collision-free trajectory between initial and final configurations as the robot moves. The presented method deals with the uncertainties associated with the unknown kinematic properties of intermediate via points since they are generated as the algorithm evolves looking for the solution. Additionally, the objective of this algorithm is to minimize the trajectory time, which guides the robot motion. The method has been applied successfully to the PUMA 560 robotic system. Four operational parameters (execution time, computational time, end-effector distance traveled, and significant points distance traveled) have been computed to study and analyze the algorithm efficiency. The experimental results show that the proposed optimization algorithm for the trajectory planning problem of an industrial robot is feasible.
DIFFERENCES IN THE SENSITISATION TO RAGWEED POLLEN AND OCCURRENCE OF LATE SUMMER ALLERGIC SYMPTOMS BETWEEN NATIVE AND IMMIGRANT WORKERS OF THE NUCLEAR POWER PLANT OF HUNGARY

Regular medical screening including allergic symptoms of workers of the Nuclear Power Plant in Paks, Hungary, offered a unique opportunity to study the influence of the environmental factors on the development of allergy. The city Paks has been one the areas of the country most heavily exposed to ragweed pollen allergens. The occurrence and extent of sensitisation assessed by skin prick test to common allergens and prevalence of seasonal and perennial allergic symptoms were compared among 880 workers (695 immigrants, 185 natives) with self-reported allergic symptoms. The percentage of sensitised people against common allergens (ragweed, grass, D. pteronyssinus) was almost the same in the natives and immigrants. When, however, the strength of sensitivity to ragweed was determined by quantitative skin prick test and specific IgE determination, significantly (P<0.0001) more immigrants (69%) than native workers (20%) exhibited high sensitivity to ragweed and the titres of specific IgE antibodies was also significantly (p<0.0001) higher in the former group. Similar differences were found in the occurrence and type of allergic symptoms. Seasonal symptoms alone occurred in 69% and 38% of the immigrant and native workers (p<0.0001). This difference was mostly due to those with late summer symptoms characteristic to ragweed allergy. These symptoms occurred in 57% of the immigrant workers, much more frequently (p<0.0001) than in the natives (18%). Our findings indicate that the length of exposure to an inhalant allergen does affect the extent of sensitisation to ragweed allergen and markedly influences the clinical symptoms that develop in the ragweed allergic patients upon allergen exposure. It can be assumed that the natives who have been living with ragweed pollen for a long time (that is were exposed to natural immunotherapy), developed a natural tolerance to it.
Cyclophosphamide and low-dose prednisolone in idiopathic pulmonary fibrosis and fibrosing nonspecific interstitial pneumonia

The present study compared the efficacy of cyclophosphamide combined with low-dose prednisolone in the treatment of idiopathic pulmonary fibrosis (IPF) with efficacy in idiopathic fibrosing nonspecific interstitial pneumonia fibrosing (NSIP). A total of 27 patients with IPF and 12 patients with fibrosing NSIP were included in this study. All patients had undergone surgical lung biopsy. The diagnoses were made based on clinical, radiological and pathological findings. All patients were treated with intermittent pulse therapy with methylprednisolone for 4 weeks, followed by cyclophosphamide with low-dose prednisolone. According to pulmonary function tests, four of 27 patients with IPF had improved, 22 remained unchanged, and one had worsened at the completion of pulse therapy. After 1 yr of combination therapy, four of 27 patients had improved, 14 remained unchanged, and nine had worsened. After pulse therapy, four of 12 patients with fibrosing NSIP had improved, and eight remained unchanged. After 1 yr of combination therapy, eight of 12 patients had improved, four remained unchanged, and none had worsened. Median survival of IPF patients was 4.1 yrs, which is significantly worse than that of fibrosing NSIP patients. In conclusion, patients with fibrosing nonspecific interstitial pneumonia had a more favourable response to combination therapy and a better survival than those with idiopathic pulmonary fibrosis.
Satellite Parameter Estimation using Combination Strategy

Indian regional Navigation Satellite system (IRNSS) is going to be an independent, indigenous navigation satellite system fully controlled by India, planned by ISRO. A system was designed of regional navigation satellite constellation, as an alternate to GPS constellation, for providing space based navigation support to various land, sea and air navigation users over the Indian region. The proposed IRNSS constellation consists of 7 satellites (3 in GEO and 4 in inclined GSO with 29 deg inclination). The continuous visibility of GEO and GSO satellites for near-equator regions provides a promising alternative for regional navigation. The Signal In Space (SIS) broadcasts satellite ephemeris in quasi keplarian elements and satellite clock coefficients which forms the primary navigation parameters generated from navigation software located at INC (ISRO Navigation Centre), bylalu, India. The determination of these parameters is performed by two types of technique, batch least square (BLS) and Extended Kalman Filter
