    1998-01-01

    Audio computer-assisted self interviewing (Audio-CASI) technologies have recently been shown to provide important and sometimes dramatic improvements in the quality of survey measurements. This is particularly true for measurements requiring respondents to divulge highly sensitive information such as their sexual, drug use, or other sensitive behaviors. However, DOS-based Audio-CASI systems that were designed and adopted in the early 1990s have important limitations. Most salient is the poor control they provide for manipulating the video presentation of survey questions. This article reports our experiences adapting Audio-CASI to Microsoft Windows 3.1 and Windows 95 platforms. Overall, our Windows-based system provided the desired control over video presentation and afforded other advantages including compatibility with a much wider array of audio devices than our DOS-based Audio-CASI technologies. These advantages came at the cost of increased system requirements --including the need for both more RAM and larger hard disks. While these costs will be an issue for organizations converting large inventories of PCS to Windows Audio-CASI today, this will not be a serious constraint for organizations and individuals with small inventories of machines to upgrade or those purchasing new machines today.

    The Climate Adaptation Science Investigators (CASI) Workgroup is comprised of NASA Earth scientists, applications researchers and institutional stewards, tasked with assisting the development of Climate Change Adaptation strategies for NASA as a whole as well as at individual Centers. In an Executive Order dated October 5, 2009, titled "Federal Leadership in Environmental, Energy, and Economic Performance" the President mandates that all agencies "evaluate agency climate-change risks and vulnerabilities to manage the effects of climate change on the agency's operations and mission in both the short and long-term." To further these goals, the CASI Workgroup contributes to the scientific advancement of relevant climate and impacts studies at the Center-scale, contributes to a body of knowledge on how to apply Earth science in decision-making and ensures that NASA institutional stewards' decision-making process benefits from the best available scientific information. Climate variability and climate change pose a range of hazards to the NASA Centers located throughout the country. These changing climate hazards may challenge key NASA missions by threatening operations and damaging critical infrastructure. Studying and understanding these hazards are essential to ensuring effective risk management for the centers. By developing climate change adaptation strategies tailored to the specific impacts that are anticipated, NASA decision makers will be able to minimize negative effects of climate and climate change, while leveraging positive outcomes. The NASA CASI Workgroup will perform a variety of tasks including development of climate projections for each Center, inventory of climate and climate impact data and project activities within NASA, assessment of adaption approaches and Center-level planning strategies, recommendations for future research initiatives, and leading of thematic and region-specific workshops.

    Full Text Available Objective. The aim of this study was to monitor the total mercury (T-Hg concentrations in fish from the Urrá reservoir, after impoundment. Materials and methods. Five fish species at different trophic levels were sampled from 2004 to 2009 and analyzed by cold-vapor atomic absorption spectroscopy for T-Hg concentrations in muscle tissue. Water quality parameters were evaluated. Results. The highest (1.39±0.69 μg/g ww and lowest (0.15±0.02 μg/g ww T-Hg concentrations were detected in Hoplias malabaricus (piscivorous and Cyphocharax magdalenae (iliophagous/detritivorous respectively, whereas Leporinus muyscorum (omnivorous had an intermediate level (0.40±0.11 μg/g ww. The organic matter content in the water increased with time and depth, whereas dissolved oxygen and pH decreased. A covariance analysis (with fish length as a covariate shows a steady increase of T-Hg levels in all the studied species after impoundment. Conclusions. The T-Hg concentrations in the evaluated fish species, increased after impoundment. The water quality variables showed conditions favoring Hg methylation and its biomagnification, this last was evident in the fish food chain of the reservoir.

    Full Text Available The most common postoperative complications of total gastrectomy are esophagojejunal anastomotic leakage and subphrenic abscess. These complications are a cause of morbility and mortality, relaparotomy, and longer postoperative stay. The use of abdominal drains is useful for the early diagnosis and management of anastomotic leaks. The aim of this study was to analyze our experience with total gastrectomy for gastric cancer in patients with and without abdominal drains, and to evaluate the results regarding postoperative morbidity, postoperative hospital stay, postoperative days for oral intake, relapatorotomy and mortality. This prospective and randomized study examines the results in 60 consecutive patients (43 males and 17 females with gastric cancer who underwent total gastrectomy in the Regional Clinical Hospital of Concepción, Chile, between 2000 and 2003. Patients were divided into two groups: group I (without drains and group II (two drains. We found 31 patients in group I and 29 patients in group II. The mean length of postoperative stay was 12.9 days in group I and 18.8 days in group II (p = 0.0242, s.. Morbidity was 9.7% in group I and 37.9% in group II (p = 0.0242, s.. Re-explorations were more frequent in group II (24.1% versus group I (9.7% (p = 0.1239, n.s.. Postoperative days for oral intake were 9.4 in group I and 12.8 in group II (p = 0.0514, n.s. Mortality was 0% in group I and 3.4% in group II (p = 0.4833, n.s.. In our experience, morbidity and postoperative hospital stay were statistically higher in the group of patients with abdominal drains.

    This paper describes a new interview data collection system that uses a laptop personal computer equipped with a touch-sensitive video monitor. The touch-screen-based audio computer-assisted self-interviewing system, or touch screen audio-CASI, enhances the ease of use of conventional audio CASI systems while simultaneously providing the privacy of self-administered questionnaires. We describe touch screen audio-CASI design features and operational characteristics. In addition, we present data from a recent clinic-based experiment indicating that the touch audio-CASI system is stable, robust, and suitable for administering relatively long and complex questionnaires on sensitive topics, including drug use and sexual behaviors associated with HIV and other sexually transmitted diseases.

    Full Text Available The airborne spectroradiometers AHS and CASI were used as a source of hyperspectral and thermal remote sensing data during the REFLEX campaign. Data geolocation and a first simple atmospheric correction was performed by INTA in near-real time with a specific on-site setup and distributed to all campaign participants. In this paper we present briefly the AHS and CASI REFLEX flight campaign followed by a detailed description of the methodology used for image processing and finally the results obtained in terms of image quality. As a conclusion, near-real time processing for AHS and CASI level 1 geolocated products was successful as most of CASI level 2 results but further work is needed for achieving accurate AHS level 2 products.

    Obiettivi: é noto che effettuare diagnosi di Legionellosi risulta difficile a causa della sovrapposizione della sintomatologia con altre forme di polmonite. Questo spiega, in parte, perché i casi di Legionellosi siano sottostimati. I metodi diagnostici disponibili, sebbene richiedano tempi relativamente lunghi, sono necessari per l’esatta stima di prevalenza della Legionellosi e per gli eventuali interventi preventivi.

    Metodi: nell’Azienda Ospedaliera “G. Panico” di Tricase, seguendo i criteri delle Linee Guida della Legionellosi (G.U. 5 maggio 2000 n. 103 durante la degenza dei pazienti che presentavano segni clinici ed obiettivi di polmonite sono state eseguite indagini radiologiche (Rx Torace, TAC, esami di laboratorio (espettorato, sangue, urina ed avviata terapia antibiotica (macrolidi e cefalosporine di III generazione. L’antigene urinario e le IgG anti-Legionella (metodo IFA, sono stati determinati in collaborazione con il Laboratorio di riferimento Regionale.

    Risultati: nel periodo ottobre 2001 gennaio 2003 sono stati notificati nel nostro ospedale 11 casi di Legionellosi accertati da indagini clinico-strumentali e di laboratorio: tutti i casi avevano titoli anticorpali abbastanza elevati, confermati poi da un secondo controllo a distanza di tempo. Solo due hanno presentato una positività per l’antigene urinario. All’atto della dimissione, per il 63.6% dei casi è stato documentato un miglioramento delle condizioni clinico-laboratoristico-strumentali, nel 18.2% si è avuta una effettiva guarigione. La letalità è stata pari al 18.2%. In tutti casi si è provveduto alla sorveglianza ambientale.

    Considerazioni: i nostri dati evidenziano che i casi di Legionellosi registrati sono stati tutti di tipo comunitario. Una corretta applicazione delle Linee Guida nel sistema di notifica permette l’avvio dell’attività di prevenzione oltre

  16. A conserved function of C. elegans CASY-1 calsyntenin in associative learning.

    Directory of Open Access Journals (Sweden)

    Frédéric J Hoerndli

    Full Text Available BACKGROUND: Whole-genome association studies in humans have enabled the unbiased discovery of new genes associated with human memory performance. However, such studies do not allow for a functional or causal testing of newly identified candidate genes. Since polymorphisms in Calsyntenin 2 (CLSTN2 showed a significant association with episodic memory performance in humans, we tested the C. elegans CLSTN2 ortholog CASY-1 for possible functions in the associative behavior of C. elegans. METHODOLOGY/PRINCIPAL FINDINGS: Using three different associative learning paradigms and functional rescue experiments, we show that CASY-1 plays an important role during associative learning in C. elegans. Furthermore, neuronal expression of human CLSTN2 in C. elegans rescues the learning defects of casy-1 mutants. Finally, genetic interaction studies and neuron-specific expression experiments suggest that CASY-1 may regulate AMPA-like GLR-1 glutamate receptor signaling. CONCLUSION/SIGNIFICANCE: Our experiments demonstrate a remarkable conservation of the molecular function of Calsyntenins between nematodes and humans and point at a role of C. elegans casy-1 in regulating a glutamate receptor signaling pathway.

    2011-01-01

    ABSTRACT The current global economic crisis is forcing governments to consider a variety of methods to generate funds for infrastructure. In the United States, smoking-related illness and an obesity epidemic are forcing public health institutions to consider a variety of methods to influence health behaviors of entire target groups. In this paper, the author uses a public health nursing model, the Public Health Code of Ethics (Public Health Leadership Society, 2002), the American Nurses' Association (ANA) Code of Ethics (2001), and other relevant ethical theory to weigh and balance the arguments for and against the use of sin taxes. A position advocating the limited use of sin taxes is supported as a reasonable stance for the public health professional.

    Full Text Available MAIN OBJECTIVES: The narcissistic personality is characterized by grandiosity, entitlement, and low empathy. This paper describes the development and validation of the Single Item Narcissism Scale (SINS. Although the use of longer instruments is superior in most circumstances, we recommend the SINS in some circumstances (e.g. under serious time constraints, online studies. METHODS: In 11 independent studies (total N = 2,250, we demonstrate the SINS' psychometric properties. RESULTS: The SINS is significantly correlated with longer narcissism scales, but uncorrelated with self-esteem. It also has high test-retest reliability. We validate the SINS in a variety of samples (e.g., undergraduates, nationally representative adults, intrapersonal correlates (e.g., positive affect, depression, and interpersonal correlates (e.g., aggression, relationship quality, prosocial behavior. The SINS taps into the more fragile and less desirable components of narcissism. SIGNIFICANCE: The SINS can be a useful tool for researchers, especially when it is important to measure narcissism with constraints preventing the use of longer measures.

    In anticipation of deep space travel, new materials are being explored to assist and relieve humans in dangerous environments, such as high radiation, extreme temperature, and extreme pressure. Ras Labs Synthetic Muscle - electroactive polymers (EAPs) that contract and expand at low voltages - which mimic the unique gentle-yet-strong nature of human tissue, is a potential asset to manned space travel through protective gear and human assist robotics and for unmanned space exploration through deep space. Generation 3 Synthetic Muscle was proven to be resistant to extreme temperatures, and there were indications that these materials may also be radiation resistant. The purpose of the Ras Labs-CASIS-ISS Experiment is to test the radiation resistivity of the third and fourth generation of these EAPs, as well as to make them even more radiation resistant or radiation hardened. On Earth, exposure of the Generation 3 and Generation 4 EAPs to a Cs-137 radiation source for 47.8 hours with a total dose of 305.931 kRad of gamma radiation was performed at the US Department of Energy's Princeton Plasma Physics Laboratory (PPPL) at Princeton University, followed by pH, peroxide, Shore Hardness Durometry, and electroactivity testing to determine the inherent radiation resistivity of these contractile EAPs and to determine whether the EAPs could be made even more radiation resistant through the application of appropriate additives and coatings. The on Earth preliminary tests determined that selected Ras Labs EAPs were not only inherently radiation resistant, but with the appropriate coatings and additives, could be made even more radiation resistant. Gforce testing to over 10 G's was performed at US Army's ARDEC Labs, with excellent results, in preparation for space flight to the International Space Station National Laboratory (ISS-NL). Selected samples of Generation 3 and Generation 4 Synthetic Muscle™, with various additives and coatings, were launched to the ISS-NL on April

  5. Modeling the acoustics of American English /r/ using configurable articulatory synthesis (CASY)

    2001-05-01

    The claim that articulatory variation in /r/ production exhibits systematic tradeoffs to achieve a stable acoustic signal (Guenther et al., 1999) was tested using configurable articulatory synthesis (CASY) and ultrasound data. In particular, the hypothesis was tested that multiple constrictions during /r/ production are necessary to achieve a low enough F3. Ultrasound and Optotrak data from four speakers pronouncing /r/ in different vocalic contexts were used to determine where in the vocal tract the tongue gestures are placed. This data was then modeled using CASY parameters and was used to determine how the three gestures in /r/ (labial, palatal, and pharyngeal) contribute to the F3 value observed in the speech signal simultaneously recorded with the ultrasound. This was done by varying the degree and location of the lingual constrictions and the degree of the labial constriction and determining the effect on F3. It was determined that the three gestures in /r/ contribute in differing amounts to the overall F3 lowering. Furthermore, it does not seem that all three gestures are necessary for F3 lowering. This lends support to the hypothesis that the goal in /r/ production is the simultaneous achievement of three gestures. [Work supported by NIH Grant DC-02717.

    Full Text Available En un análisis crítico de los sistemas psicoterapéuticos contemporáneos, el autor comienza señalando que los progresos en medicina han sido mucho mayores que en psiquiatría. Afirma que los avances deben darse básicamente desde la psicología. Se pregunta cuál ha sido la evolución y el progreso de la psicoterapia. Afirma que la prevalencia del psicoanálisis en algunos países no es necesariamente criterio de verdad y legitimidad científica del sistema freudiano. Al indagar si han evolucionado las psicoterapias considera que algunas se cerraron, como el psicoanálisis, otras evolucionaron y se ampliaron como el conductismo. Hoy la terapia del comportamiento se ha separado considerablemente del conductismo original. La solución no es el eclecticismo. Se necesita ser congruente y sistemático. La solución es una psicoterapia sin adjetivos

    Full Text Available This article engages with John Haught’s views on original sin. It offers a brief orientation todiscourse on sin in the context of theological debates on human evolution. This is followed bya thick description of Haught’s so-called note on original sin. A series of five observations andquestions regarding Haught’s position is offered. It is observed that Haught’s way of tellingthe story of sin and salvation follows a classic Roman Catholic plot, namely one based on graceelevating nature. This is contrasted with the more typically reformed plot of restoration.

    Mapping of coral reefs provides information to support the conservation and monitoring of this vulnerable benthic habitat. Coral reef environment has a high level of complexity and spatial heterogeneity, however, typical maps derived using remote sensing data only includes classification of benthic communities. The study aims to update the status of coral reef classification through the advancement of remote sensing technology in the Philippines. This shows the coral community condition in the area. With the use of hyperspectral Compact Airborne Spectrographic Imager (CASI) and bathymetric LiDAR, data were acquired in Apo Reef, Province of Mindoro. Apo Reef is known as the second largest contiguous coral reef in the world. The image taken has a spatial resolution of 0.5 meters with spectral resolution of approximately 10nm between 385nm to 1047nm wavelength regions. Pre-processing of LiDAR data includes extraction of surface bottom and generating derivatives such as Digital Surface Model (DSM), Digital Terrain Model (DTM), rugosity, and slope. Data on spectral reflectance of coral reef types and other substrates, bathymetry, validation points and geotagged underwater video were gathered in situ simultaneous with the image acquisition. Derivative analysis is then applied to the field spectra to determine the wavelength bands for discriminating coral reef types. The optimal subset bands and LiDAR derivatives were used in classifying coral reef types using the supervised classification. Geotagged photos and sampling points were used to validate and assess the accuracy of the map.

    Full Text Available This study used a reef-up approach to map coral reef benthos, substrates and bathymetry, with high spatial resolution hyperspectral image data. It investigated a physics-based inversion method for mapping coral reef benthos and substrates using readily available software: Hydrolight and ENVI. Compact Airborne Spectrographic Imager (CASI data were acquired over Heron Reef in July 2002. The spectral reflectance of coral reef benthos and substrate types were measured in-situ, and using the HydroLight 4.2 radiative transfer model a spectral reflectance library of subsurface reflectance was simulated using water column depths from 0.5–10.0 m at 0.5 m intervals. Using the Spectral Angle Mapper algorithm, sediment, benthic micro-algae, algal turf, crustose coralline algae, macro-algae, and live coral were mapped with an overall accuracy of 65% to a depth of around 8.0 m; in waters deeper than 8.0 m the match between the classified image and field validation data was poor. Qualitative validation of the maps showed accurate mapping of areas dominated by sediment, benthic micro-algae, algal turf, live coral, and macro-algae. A bathymetric map was produced for water column depths 0.5–10.0 m, at 0.5 m intervals, and showed high correspondence with in-situ sonar data (R2 value of 0.93.

    We compared 2 rating scales with different manic symptom items on diagnostic accuracy for detecting pediatric bipolar spectrum disorder (BPSDs) in outpatient mental health clinics. Participants were 681 parents/guardians of eligible children (465 male, mean age = 9.34) who completed the Parent General Behavior Inventory-10-item Mania (PGBI-10 M) and mania subscale of the Child and Adolescent Symptom Inventory-Revised (CASI-4R). Diagnoses were based on KSADS interviews with parent and youth. Receiver operating characteristic (ROC) analyses and diagnostic likelihood ratios (DLRs) determined discriminative validity and provided clinical utility, respectively. Logistic regressions tested for incremental validity in the CASI-4R mania subscale and PGBI-10 M in predicting youth BPSD status above and beyond demographic and common diagnostic comorbidities. Both CASI-4R and PGBI-10 M scales significantly distinguished BPSD (N = 160) from other disorders (CASI-4R: Area under curve (AUC) = .80, p M: AUC = 0.79, p  0.05). Diagnostic likelihood ratios indicated low scores on either scale (CASI: 0-5; PGBI-10 M: 0-6) cut BPSD odds to 1/5 of those with high scores (CASI DLR- = 0.17; PGBI-10 M DLR- = 0.18). High scores on either scale (CASI: 14+; PGBI-10 M: 20+) increased BPSD odds about fourfold (CASI DLR+ = 4.53; PGBI-10 M DLR+ = 3.97). Logistic regressions indicated the CASI-4R mania subscale and PGBI-10 M each provided incremental validity in predicting youth BPSD status. The CASI-4R is at least as valid as the PGBI-10 M to help identify BPSDs, and can be considered as part of an assessment battery to screen for pediatric BPSDs.

    Full Text Available Ethical or responsible investing has attracted much attention over the last decade. Financial planners can nowadvise clients on a broad range of ethical investment products and some financial planning firms have this astheir sole activity. Interestingly, the alter ego of ethical investing, sin or vice investing, has attracted far lessattention. Recent research shows that ‘sinful’ investments can generate very strong returns and shouldcertainly not be avoided by investors without a full evaluation of the consequences of excluding theseinvestments from the portfolio. This paper extends these findings into the field of self managedsuperannuation funds operating within an Australian context. The prevalence of sinful investments within asample of SMSFs and the returns that may be generated by a portfolio consisting of sinful Australian equitiesis examined. Analysis reveals that the SMSF investors within the sample do not include very many sin stocksin their portfolios. However, it does not appear as though SMSF trustees are missing an important investmentopportunity because the analysis reveals that an equally-weighted portfolio of all vice or sin shares is unlikelyto generate superior returns.

    The effect of the Ca/Si ratio of the calcium–silicate–hydrate (C–S–H) phase on the interaction with sulfate ions is investigated for C–S–H phases (Ca/Si = 0.83, 1.25, 1.50) and mortar samples of blended Portland cements. It is shown that leaching of calcium from C–S–H and portlandite affects the composition of the pore solution and contributes to the developing crystallization pressure of ettringite. Sulfate profiles show that sulfate binding before cracking is similar for different Ca/Si ratios whereas the highest expansion rates are observed for the mortars with the highest Ca/Si ratios. After leaching in sulfate solutions, the C–S–H samples have been characterized by {sup 29}Si MAS NMR, thermogravimetric analysis, and elemental solution analysis. Generally, the exposure to sulfate solutions results in decalcification of the C–S–H, which increases with decreasing Ca/Si ratio. The data are in good agreement with thermodynamic modeling, indicating that equilibrium is almost achieved in the leached systems. Finally, the expansion of mortar samples exposed to sulfate solutions was much less at lower Ca/Si ratios of the cement blends. This reduced expansion can be related to the decrease of the supersaturation of the pore solution with respect to ettringite at lower Ca/Si ratios of the C–S–H and in the absence of portlandite.

    Anxiety sensitivity (AS) is a risk factor for the development of anxiety disorders in youth. To date, the applicability of the Childhood Anxiety Sensitivity Index (CASI) in youth from a low or middle income country (LMIC) setting on the African continent has not been assessed. A representative sample of 1149 secondary school learners from 29 schools in Cape Town, South Africa, participated in the study. Participants completed the CASI on a single occasion. One-, two-, and four-factor models of the CASI were assessed. A one-factor solution that comprised items predominantly represented by physical concerns appeared to provide the best fit to our data, however, relatively low variance (26%) was explained. Subsequent item deletion resulted in a 9-item 'physical concerns' factor that showed good construct reliability (0.83) but also explained a low amount of variance (35%). In terms of gender, a one-factor model provided the best fit, however, low variance was explained (i.e., 25%). Configural, metric and scalar invariance of the CASI by gender was determined. Our results suggest that the 18-item CASI is not applicable to our target population and may require adaptation in this population; however, replication of this study in other multicultural adolescent samples in South Africa is first needed to further assess the validity of the AS construct as measured by the CASI.

    Developing an understanding of the distribution and changes in estuarine and riparian habitats is critical to the management of biological resources in the lower Columbia River. In a recently completed comprehensive ecosystem protection and enhancement plan for the lower Columbia River Estuary (CRE), Jerrick (1999) identified habitat loss and modification as one of the key threats to the integrity of the CRE ecosystem. This management plan called for an inventory of habitats as key first step in the CRE long-term restoration effort. While previous studies have produced useful data sets depicting habitat cover types along portions of the lower CRE (Thomas, 1980; Thomas, 1983; Graves et al., 1995; NOAA, 1997; Allen, 1999), no single study has produced a description of the habitats for the entire CRE. Moreover, the previous studies differed in data sources and methodologies making it difficult to merge data or to make temporal comparisons. Therefore, the Lower Columbia River Estuary Partnership (Estuary Partnership) initiated a habitat cover mapping project in 2000. The goal of this project was to produce a data set depicting the current habitat cover types along the lower Columbia River, from its mouth to the Bonneville Dam, a distance of {approx}230-km (Fig. 1) using both established and emerging remote sensing techniques. For this project, we acquired two types of imagery, Landsat 7 ETM+ and Compact Airborne Spectrographic Imager (CASI). Landsat and CASI imagery differ in spatial and spectral resolution: the Landsat 7 ETM+ sensor collects reflectance data in seven spectral bands with a spatial resolution of 30-m and the CASI sensor collects reflectance data in 19 bands (in our study) with a spatial resolution of 1.5-m. We classified both sets of imagery and produced a spatially linked, hierarchical habitat data set for the entire CRE and its floodplain. Landsat 7 ETM+ classification results are presented in a separate report (Garono et al., 2003). This report

    2014-01-01

    This book tells the story of the Swiss Institute for Nuclear Research (SIN). The institute was founded in 1968 and became part of the Paul Scherrer Institute (PSI) in 1988. Its founding occurred at a time when physics was generally considered the key discipline for technological and social development. This step was unusual for a small country like Switzerland and showed courage and foresight. Equally unusual were the accomplishments of SIN, compared with similar institutes in the rest of the world, as well as its influence on Swiss, and partially also on international politics of science. That this story is now available in a widely understandable form is due to the efforts of some physicists, who took the initiative as long as contemporary witnesses could still be questioned. As is usually the case, official documents always show just an excerpt of what really happened. An intimate portrayal of people who contributed to success requires personal memories. This text relies on both sources. In addition, the e...

    This thesis presents a measurement of the time-dependent asymmetry in the rate of {anti B}{sub d}{sup 0} versus B{sub d}{sup 0} decays to J/{psi}K{sub s}{sup 0}. In the context of the Standard Model this is interpreted as a measurement of the CP violation parameter sin(2{beta}). A total of 198{+-}17 B{sub d}{sup 0}/{anti B}{sub d}{sup 0} decays were observed in p{anti p} collisions at {radical}s=1.8 TeV by the CDF detector at the Fermilab Tevatron. The initial B flavor (whether B{sup 0} or {anti B}{sup 0}) is determined by a same-side flavor tagging technique. The analysis results in sin(2{beta})=1.8{+-}1.1(stat.){+-}0.3(syst.). This analysis demonstrates the feasibility of studying CP violation in the B{sup 0}-{anti B}{sup 0} system at a hadron collider. By applying the methods used in this analysis, future, higher-statistics experiments should be able to tightly constrain the parameters of the Standard Model.

    This thesis presents a measurement of the time-dependent asymmetry in the rate of $\\bar{B}$$0\\atop{d}$ versus B$0\\atop{d}$ decays to J/ΨK$0\\atop{s}$. In the context of the Standard Model this is interpreted as a measurement of the CP violation parameter sin(2β). A total of 198{+-}17 B$0\\atop{d}$/$\\bar{B}$$0\\atop{d}$ decays were observed in p$\\bar{p}$ collisions at √s=1.8 TeV by the CDF detector at the Fermilab Tevatron. The initial B flavor (whether B0 or $\\bar{B}$0) is determined by a same-side flavor tagging technique. The analysis results in sin(2β)=1.8±1.1(stat.)±0.3(syst.). This analysis demonstrates the feasibility of studying CP violation in the B0-$\\bar{B}$0 system at a hadron collider. By applying the methods used in this analysis, future, higher-statistics experiments should be able to tightly constrain the parameters of the Standard Model.

Se diseñó una tarea de igualación de la muestra de segundo orden empleando relaciones directas entre estímulos geométricos. Se utilizó un diseño pretestpostest con tres fases de entrenamiento y pruebas de transferencia. Los resultados parecen indicar la importancia de la adquisición en un modo morfológicamente complejo para su transferencia hacia otros modos menos complejos, y que la ausencia de la retroalimentación reactiva afecta negativamente el nivel de adquisición y transferencia de los modos lingüísticos.

    Mustard is a condiment added to a variety of foodstuffs and a frequent cause of food allergy. A new strategy for the detection of mustard allergen in food products is presented. The methodology is based on liquid chromatography analysis coupled to mass spectrometry. Mustard allergen Sin a 1 was purified from yellow mustard seeds. Sin a 1 was detected with a total of five peptides showing a linear response (lowest LOD was 5ng). Sin a 1 was detected in mustard sauces and salty biscuit (19±3mg/kg) where mustard content is not specified. Sin a 1, used as an internal standard, allowed quantification of this mustard allergen in foods. A novel LC/MS/MS SRM-based method has been developed to detect and quantify the presence of mustard. This method could help to detect mustard allergen Sin a 1 in processed foods and protect mustard-allergic consumers.

    Full Text Available A land-cover-based linear BRDF (bi-directional reflectance distribution function unmixing (LLBU algorithm based on the kernel-driven model is proposed to combine the compact airborne spectrographic imager (CASI reflectance with the moderate resolution imaging spectroradiometer (MODIS daily reflectance product to derive the BRDF/albedo of the two sensors simultaneously in the foci experimental area (FEA of the Heihe Watershed Allied Telemetry Experimental Research (HiWATER, which was carried out in the Heihe River basin, China. For each land cover type, an archetypal BRDF, which characterizes the shape of its anisotropic reflectance, is extracted by linearly unmixing from the MODIS reflectance with the assistance of a high-resolution classification map. The isotropic coefficients accounting for the differences within a class are derived from the CASI reflectance. The BRDF is finally determined by the archetypal BRDF and the corresponding isotropic coefficients. Direct comparisons of the cropland archetypal BRDF and CASI albedo with in situ measurements show good agreement. An indirect validation which compares retrieved BRDF/albedo with that of the MCD43A1 standard product issued by NASA and aggregated CASI albedo also suggests reasonable reliability. LLBU has potential to retrieve the high spatial resolution BRDF/albedo product for airborne and spaceborne sensors which have inadequate angular samplings. In addition, it can shorten the timescale for coarse spatial resolution product like MODIS.

  17. Bicarbonate Plays a Critical Role in the Generation of Cytotoxicity during SIN-1 Decomposition in Culture Medium

    2012-01-01

    Full Text Available 3-Morpholinosydnonimine (SIN-1 is used as a donor of peroxynitrite (ONOO− in various studies. We demonstrated, however, that, the cell-culture medium remains cytotoxic to PC12 cells even after almost complete SIN-1 decomposition, suggesting that reaction product(s in the medium, rather than ONOO−, exert cytotoxic effects. Here, we clarified that significant cytotoxicity persists after SIN-1 decomposes in bicarbonate, a component of the culture medium, but not in NaOH. Cytotoxic SIN-1-decomposed bicarbonate, which lacks both oxidizing and nitrosating activities, degrades to innocuous state over time. The extent of SIN-1 cytotoxicity, irrespective of its fresh or decomposed state, appears to depend on the total number of initial SIN-1 molecules per cell, rather than its concentration, and involves oxidative/nitrosative stress-related cell damage. These results suggest that, despite its low abundance, the bicarbonate-dependent cytotoxic substance that accumulates in the medium during SIN-1 breakdown is the cytotoxic entity of SIN-1.

    Hyperspectral remote sensing is a frontier of remote sensing. Due to its advantage of integrated image with spectrum, it can realize objects identification, superior to objects classification of multispectral remote sensing. Taken the Mingshujing area in Gansu Province of China as an example, this study extracted the alteration minerals and thus to do metallogenic prediction using CASI/SASI airborne hyperspectral data. The Mingshujing area, located in Liuyuan region of Gansu Province, is dominated by middle Variscan granites and Indosinian granites, with well developed EW- and NE-trending faults. In July 2012, our project team obtained the CASI/SASI hyperspectral data of Liuyuan region by aerial flight. The CASI hyperspectral data have 32 bands and the SASI hyperspectral data have 88 bands, with spectral resolution of 15nm for both. The hyperspectral raw data were first preprocessed, including radiometric correction and geometric correction. We then conducted atmospheric correction using empirical line method based on synchronously measured ground spectra to obtain hyperspectral reflectance data. Spectral dimension of hyperspectral data was reduced by the minimum noise fraction transformation method, and then purity pixels were selected. After these steps, image endmember spectra were obtained. We used the endmember spectrum election method based on expert knowledge to analyze the image endmember spectra. Then, the mixture tuned matched filter (MTMF) mapping method was used to extract mineral information, including limonite, Al-rich sericite, Al-poor sericite and chlorite. Finally, the distribution of minerals in the Mingshujing area was mapped. According to the distribution of limonite and Al-rich sericite mapped by CASI/SASI hyperspectral data, we delineated five gold prospecting areas, and further conducted field verification in these areas. It is shown that there are significant gold mineralized anomalies in surface in the Baixianishan and Xitan prospecting

    Full Text Available Tomando como base la lectura del cuento "Juan Sin Miedo" realizada por tres sujetos adolescentes, pretendo responder a la pregunta sobre los principales temores que enfrenta la población costarricense adolescente en la actualidad. Las respuestas giran en torno a tres núcleos significativos: el miedo a la exclusión económica y social, materializada en el trato discriminatorio hacia quienes no se adecuan a los criterios impuestos por la sociedad de consumo; el miedo a la escuela, en tanto excluye a quienes no se ajustan a la norma esperada de desempeño académico; y el miedo al otro, en particular a la calle y la escuela como espacios de violencia. Concluyo señalando que, detrás de dichos temores, es posible leer un anhelo de pertenencia; de aprecio sincero y gratuito, en que no medie el rendimiento académico de la persona; así como un anhelo de seguridad en el entorno cercano.

  6. Improved Aerosol Optical Thickness, Columnar Water Vapor, and Surface Reflectance Retrieval from Combined CASI and SASI Airborne Hyperspectral Sensors

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available An increasingly common requirement in remote sensing is the integration of hyperspectral data collected simultaneously from different sensors (and fore-optics operating across different wavelength ranges. Data from one module are often relied on to correct information in the other, such as aerosol optical thickness (AOT and columnar water vapor (CWV. This paper describes problems associated with this process and recommends an improved strategy for processing remote sensing data, collected from both visible to near-infrared and shortwave infrared modules, to retrieve accurate AOT, CWV, and surface reflectance values. This strategy includes a workflow for radiometric and spatial cross-calibration and a method to retrieve atmospheric parameters and surface reflectance based on a radiative transfer function. This method was tested using data collected with the Compact Airborne Spectrographic Imager (CASI and SWIR Airborne Spectrographic Imager (SASI from a site in Huailai County, Hebei Province, China. Various methods for retrieving AOT and CWV specific to this region were assessed. The results showed that retrieving AOT from the remote sensing data required establishing empirical relationships between 465.6 nm/659 nm and 2105 nm, augmented by ground-based reflectance validation data, and minimizing the merit function based on AOT@550 nm optimization. The paper also extends the second-order difference algorithm (SODA method using Powell’s methods to optimize CWV retrieval. The resulting CWV image has fewer residual surface features compared with the standard methods. The derived remote sensing surface reflectance correlated significantly with the ground spectra of comparable vegetation, cement road and soil targets. Therefore, the method proposed in this paper is reliable enough for integrated atmospheric correction and surface reflectance retrieval from hyperspectral remote sensing data. This study provides a good reference for surface

    Team members from NASA Ames Research Center developed a mission planning tool using Google Earth to support mission planning and monitoring during the Characterization of Sea Ice (CASIE) 2009 Mission to Svalbard, Norway. The tool allowed both deployed and non-deployed team members to view near-real time satellite imagery, ancillary information and flight paths before, during and after flights. MODIS, QuikSCAT, and AMSR-E data were displayed in Google Earth as ground overlays. MODIS data included two true color images (one each from Aqua and Terra) and a false color image (bands 3, 6, and 7) from Terra. The images were converted from GeoTIFF format to KML format using GDAL and provided cloud information to flight planners. The QuikSCAT and AMSR-E satellite imagery provided information on ice location and concentration, which allowed flight planners to locate areas for data collection. Ancillary information included sounding data, icing and snow cover forecasts, cloud pressure, perceptible water, and surface temperature data. Before flying, flight paths were created in Google Earth and then converted into shapefiles for input into flight software. While in-flight, the plane sent position, temperature, and humidity data to the base station in Ny-Ålesund. These data were converted into KML format and displayed within Google Earth in near-real time. The simultaneous display of satellite data, weather forecasts, and real-time data from the aircraft allowed mission planners to make real time mission operation decisions and allowed for remote mission monitoring by team members not deployed to Svalbard.

    In recent decades, many spectral vegetation indices (SVIs) have been proposed to estimate the leaf nitrogen concentration (LNC) of crops. However, most of these indices were based on the field hyperspectral reflectance. To test whether they can be used in aerial remote platform effectively, in this work a comparison of the sensitivity between several broad-band and red edge-based SVIs to LNC is investigated over different crop types. By using data from experimental LNC values over 4 different crop types and image data acquired using the Compact Airborne Spectrographic Imager (CASI) sensor, the extensive dataset allowed us to evaluate broad-band and red edge-based SVIs. The result indicated that NDVI performed the best among the selected SVIs while red edge-based SVIs didn't show the potential for estimating the LNC based on the CASI data due to the spectral resolution. In order to search for the optimal SVIs, the band combination algorithm has been used in this work. The best linear correlation against the experimental LNC dataset was obtained by combining the 626.20nm and 569.00nm wavebands. These wavelengths correspond to the maximal chlorophyll absorption and reflection position region, respectively, and are known to be sensitive to the physiological status of the plant. Then this linear relationship was applied to the CASI image for generating an LNC map, which can guide farmers in the accurate application of their N fertilization strategies.

  12. SinR controls enterotoxin expression in Bacillus thuringiensis biofilms.

    Directory of Open Access Journals (Sweden)

    Annette Fagerlund

    Full Text Available The entomopathogen Bacillus thuringiensis produces dense biofilms under various conditions. Here, we report that the transition phase regulators Spo0A, AbrB and SinR control biofilm formation and swimming motility in B. thuringiensis, just as they control biofilm formation and swarming motility in the closely related saprophyte species B. subtilis. However, microarray analysis indicated that in B. thuringiensis, in contrast to B. subtilis, SinR does not control an eps operon involved in exopolysaccharides production, but regulates genes involved in the biosynthesis of the lipopeptide kurstakin. This lipopeptide is required for biofilm formation and was previously shown to be important for survival in the host cadaver (necrotrophism. Microarray analysis also revealed that the SinR regulon contains genes coding for the Hbl enterotoxin. Transcriptional fusion assays, Western blots and hemolysis assays confirmed that SinR controls Hbl expression, together with PlcR, the main virulence regulator in B. thuringiensis. We show that Hbl is expressed in a sustained way in a small subpopulation of the biofilm, whereas almost all the planktonic population transiently expresses Hbl. The gene coding for SinI, an antagonist of SinR, is expressed in the same biofilm subpopulation as hbl, suggesting that hbl transcription heterogeneity is SinI-dependent. B. thuringiensis and B. cereus are enteric bacteria which possibly form biofilms lining the host intestinal epithelium. Toxins produced in biofilms could therefore be delivered directly to the target tissue.

MÉTODO: Mediante un proceso Delphi en el que participaron 25 médicos, cirujanos o anestesistas, del Servei Valencià de la Salut (SVS, se obtuvo un consenso sobre los criterios objetivos de exclusión de pacientes para CSI y sobre la proporción de determinadas intervenciones que podrían realizarse ambulatoriamente, criterios que fueron aplicados al Conjunto Mínimo de Datos Básicos (CMBD al alta hospitalaria de la Comunidad Valenciana para estimar los ingresos y estancias evitables por CSI en una selección de 29 procesos quirúrgicos. RESULTADOS: El 83% de los médicos respondieron a los cuestionarios Delphi. La mediana de la estimación de los encuestados sobre la proporción de casos realizables con CSI en las diferentes patologías oscila entre el 40% para las reparaciones de hernia de pared abdominal o la colecistectomía laparoscópica, y el 90% para las escisiones de tejido perianal, anastomosis para diálisis o gangliectomía. La aplicación de las restricciones a la CSI definidas en el Delphi hubiera supuesto para el SVS la evitación de 12.558 ingresos en 1994, el 75% de los realizados en las intervenciones estudiadas, porcentaje casi idéntico al resultante de aplicar las estimaciones de los clínicos al CMBD. CONCLUSIONES: Los profesionales del SVS consideran factible un número de intervenciones sin ingreso muy superior al efectivamente realizado, siendo probablemente los sistemas de financiación e incentivos utilizados en el SNS, y no los criterios clínicos, las causas del escaso desarrollo de la CSI.

    Full Text Available Celestial Navigation System (CNS has characteristics of accurate orientation and strong autonomy and has been widely used in Hypersonic Vehicle. Since the CNS location and orientation mainly depend upon the inertial reference that contains errors caused by gyro drifts and other error factors, traditional Strap-down Inertial Navigation System (SINS/CNS positioning algorithm setting the position error between SINS and CNS as measurement is not effective. The model of altitude azimuth, platform error angles, and horizontal position is designed, and the SINS/CNS tightly integrated algorithm is designed, in which CNS altitude azimuth is set as measurement information. GPF (Gaussian particle filter is introduced to solve the problem of nonlinear filtering. The results of simulation show that the precision of SINS/CNS algorithm which reaches 130 m using three stars is improved effectively.

    GaN layers without and with an in-situ SiN mask were grown by using metal organic vapor phase epitaxy for three different approaches used in GaN on silicon(111) growth, and the physical and optical properties of the GaN layers were studied. For each approach applied, GaN layers of 1.4 μm total thickness were grown, using silan SiH{sub 4} as Si source in order to grow Si{sub x}N{sub x} masking layer. The optical micrographs, scanning electron microscope images, and atomic force microscope images of the grown samples revealed cracks for samples without SiN mask, and micropits, which were characteristic for the samples grown with SiN mask. In situ reflectance signal traces were studied showing a decrease of layer coalescence time and higher degree of 3D growth mode for samples with SiN masking layer. Stress measurements were conducted by two methods—by recording micro-Raman spectra and ex-situ curvature radius measurement—additionally PLs spectra were obtained revealing blueshift of PL peak positions with increasing stress. The authors have shown that a SiN mask significantly improves physical and optical properties of GaN multilayer systems reducing stress in comparison to samples grown applying the same approaches but without SiN masking layer.

    Full Text Available Wernicke's encephalopathy is an acute neurological syndrome due to thiamine deficiency, which is characterized by a typical triad of mental status changes, oculomotor dysfunction and ataxia. Despite the fact that Wernicke's encephalopathy, in developed countries, is frequently associated with chronic alcoholism, there have been a number of published cases associating this encephalopathy with parenteral feeding without vitamin supplementation. Diagnosis is primarily a clinical one, and can be supported by laboratory tests and imaging studies; treatment should start as soon as possible, for the morbidity and mortality (almost 20% associated with this syndrome is high. Thiamine supplementation, along with other vitamins, is recommended for patients in risk of developing this syndrome.La Encefalopatía de Wernicke es un síndrome neurológico de instauración aguda secundario a un déficit de tiamina y que se caracteriza por una típica tríada de alteración del nivel de conciencia, disfunción oculomotora y marcha atáxica. Aunque la causa más frecuente de Wernicke en nuestro medio sea el alcoholismo crónico, varios casos han sido descritos en enfermos con nutrición parenteral total sin aporte vitamínimo. El diagnóstico es principalmente clínico, apoyándose en pruebas analíticas y de neuroimagen, recomendándose empezar el tratamiento con tiamina lo más precozmente posible, dada la alta morbilidad y la alta mortalidad (de casi 20%, que se asocian a esta encefalopatía. La suplementación dietética con tiamina y otras vitaminas está indicada en todos los individuos en riesgo de desarrollar este síndrome.

    Lee, Joseph; Theol, M

    2014-04-01

    Human nature has a dark side, something important to religions. Evolutionary psychology has been used to illuminate the human shadow side, although as a discipline it has attracted criticism. This article seeks to examine the evolutionary psychology's understanding of human nature and to propose an unexpected dialog with an enduring account of human evil known as original sin. Two cases are briefly considered: murder and rape. To further the exchange, numerous theoretical and methodological criticisms and replies of evolutionary psychology are explored jointly with original sin. Evolutionary psychology can partner with original sin since they share some theoretical likenesses and together they offer insights into the nature of what it means to be human.

  1. Sin, suffering, and the need for the theological virtues.

    Science.gov (United States)

    Jones, David Albert

    2006-08-01

    This article examines the account of the relationship between sin and suffering provided by J. L. A. Garcia in "Sin and Suffering in a Catholic Understanding of Medical Ethics," in this issue. Garcia draws on the (Roman) Catholic tradition and particularly on the thought of Thomas Aquinas, who remains an important resource for Catholic theology. Nevertheless, his interpretation of Thomas is open to criticism, both in terms of omissions and in terms of positive claims. Garcia includes those elements of Thomas that are purely philosophical, such as natural law and acquired virtue, but neglects the theological and infused virtues, the gifts and fruits of the Holy Spirit, and the beatitudes. These omissions distort his account of the Christian life so that he underplays both the radical problem posed by sin (and suffering), and the radical character of the ultimate solution: redemption in Christ through the grace of the Holy Spirit.

  2. [Serotonin dysfunctions in the background of the seven deadly sins].

    2003-11-20

    The symbolic characters of the Seven Deadly Sins can be traced from time to time in the cultural history of human mankind, being directly specified in certain artistic products. Such are, among others, the painting entitled "The Seven Deadly Sins and the Four Lost Things" by Hieronymus Bosch and the poems Divina Commedia and The Foerie Queene by Dante Alighieri and Edmund Spenser, respectively. However, there are several paragraphs referring to these behaviours of the Seven Deadly Sins in the Bible and in the dramas of William Shakespeare. The objective of the present review is to propose that dysfunctions in the central serotonergic system might be involved in the neurobiology of these 'sinful' behaviour patterns. Evidences indicate that behaviour traits such as Accidia (Sloth), Luxuria (Lust, Lechery), Superbia (Pride), Ira (Wrath, Anger), Invidia (Envy), Avaritia (Greed, Avarice), and Gula (Gluttony) can relate to the functional alterations of serotonin in the brain. Results of biochemical and molecular genetic (polymorphism) studies on the human serotonergic system (receptor, transporter, enzyme), findings of functional imaging techniques, effects of depletion (or supplementation) of the serotonin precursor tryptophan, data of challenge probe investigations directed to testing central serotonergic functions, alterations in the peripheral serotonin measures (platelet), and the changes in the CSF 5-hydroxy-indoleacetic acid content indicate such serotonergic involvement. Furthermore, results of animal experiments on behaviour change (aggressive, dominant or submissive, appetite, alcohol preference) attributed to serotonin status modification and the clinically evidenced therapeutic efficacy of pharmacological interventions, based on the modulation and perturbation of the serotonergic system (e.g. selective serotonin reuptake inhibitors), in treating the 'sinful' behaviour forms and analogous pathological states reaching the severity of psychiatric disorders

    Full Text Available El principal propósito de este trabajo es mostrar que, en determinadas condiciones experimentales, es posible neutralizar la diferencia entre ambos juicios de proporción (escalas sin límites y juicios por categorías (escalas de rangos fijos. Las condiciones se relacionan con el tipo de instrucciones, el rango numérico de que dispone el observador y el rango propio de cada observador. Con el objeto de examinar este problema se realizaron dieciseis experimentos con estímulos visuales, divididos en dos series. En la pnmera se midió la función de brillo con el método de estimación de la magnitud utilizando una instrucción convencional y otra modificada. Se hicieron experimentos complementarios para verificar la forma de la función de brillo que dieron como resultado dos rectas con diferentes valores exponenciales. Luego se aplicaron los métodos de producción de la magnitud y escalas de categoría con un rango de 1 a 7, 1 a 30, 1 a lOO y 1 a 1000. En la segunda serie se midió la luminosidad de muestras grises. Se usó primeramente el método de estimación de la magnitud y de los resultados de este experimento se derivaron dos escalas de categorías. En una se tomaron los valores extremos promedios y en la otra los de cada observador. Finalmente se aplicó una técnica de escalas de categorías individuales no derivadas cuyo rango fue elegido por cada observador. Se observó que las escalas de categoría guardan una relación casi lineal con las escalas de proporciones cuando: 1 el número de categorías se aproxima o excede el rango promedio alcanzado con estimación de la magnitud, 2 cada observador fija los dos patrones, superior e inferior, de su propia escala

    2013-01-01

    Full Text Available Two viewpoints are given: (1 initial alignment of strapdown inertial navigation system (SINS can be fulfilled with a set of inertial sensor data; (2 estimation time for sensor errors can be shortened by repeated data fusion on the added backward-forward SINS resolution results and the external reference data. Based on the above viewpoints, aiming to estimate gyro bias in a shortened time, a rapid transfer alignment method, without any changes for Kalman filter, is introduced. In this method, inertial sensor data and reference data in one reference data update cycle are stored, and one backward and one forward SINS resolutions are executed. Meanwhile, data fusion is executed when the corresponding resolution ends. With the added backward-forward SINS resolution, in the above mentioned update cycle, the estimating operations for gyro bias are added twice, and the estimation time for it is shortened. In the ship swinging condition, with the “velocity plus yaw” matching, the effectiveness of this method is proved by the simulation.

  14. Stratigraphic relationships between the Colombian, Sinú Offshore and Sinú-San Jacinto basins based on seismic stratigraphy

    Directory of Open Access Journals (Sweden)

    Esteban Alfaro

    Full Text Available There are diverse controversial and contradictory models about the geological history of the Caribbean region. Some issues such as the origin of the Caribbean plate, the nature of basement of the Caribbean basins and the regional tectonics, have been in discussion during decades. There are disperse and punctual studies across the Caribbean. Application of seismic stratigraphy in regional seismic lines across the Colombian, Sinú Offshore and Sinú-San Jacinto basins suggests a stratigraphic continuity between these regions. A chronostratigraphic chart of the Colombian and Sinú Offshore basins based on stratal terminations and seismic facies was proposed. Seven stratigraphic stages were identified in the Colombian, Sinú Offshore and Sinú-San Jacinto basins, which, also, have been recognized across the Caribbean region. First stratigraphic stage was characterized by continental to restricted marine deposition during a Triassic/Jurassic rifting. Second, third and fourth stages correspond with deposition of a wide carbonate platform in the Cretaceous, sandy carbonate platform during the Paleocene and carbonate and coarse-grained fluvial sedimentation during the Eocene, respectively. Another stage was characterized by rising of base level and deep-water deposition (turbidites and pelagic/hemipelagic sediments during the Oligocene. The Early to Middle Miocene was characterized by shallow marine to fluvial sedimentation during falling base level, which was controlled by episodic events of tectonic inversion. During the Late Miocene to recent, the sedimentation consisted of terrigenous coarse-grained deposits. Stratigraphic relationships between these zones, suggest a shared geological history between the Caribbean and northern South America. The geologic continuity founded in this study is easily explained by the model of an in situ origin for the Caribbean plate.

  15. A new nonlinear optical silicate carbonate K2Ca[Si2O5](CO3) with a hybrid structure of kalsilite and soda-like layered fragments

    Single crystals of a new silicate carbonate, K2Ca[Si2O5](CO3), have been synthesized in a multi-components hydrothermal solution with a pH value close to neutral and a high concentration of a carbonate mineralizer. The new compound has an axial structure (s.g. P6322) with unit cell parameters a = 5.04789 (15), c = 17.8668 (6) Å. Pseudosymmetry of the structure corresponds to s.g. P63/mmc which is broken only by one oxygen position. The structure consists of two layered fragments: one of the type of the mineral kalsilite (KAlSiO4) and the other of the high-temperature soda-like α-Na2CO3, Ca substituting for Na. The electro-neutral layer K2[Si2O5] (denoted K) as well as the layer Ca(CO3) (denoted S) may separately correspond to individual structures. In K2Ca[Si2O5](CO3) the S-K layers are connected together via Ca-O interactions between Ca atoms from the carbonate layer and apical O atoms from the silicate one, and also via K-O interlayer interactions. A hypothetical acentric structure, sp.gr. P-62c, is predicted on the basis of the order-disorder theory. It presents another symmetrical option for the arrangement of K-layers relative to S-layers. The K,Ca-silicate-carbonate powder produces a moderate SHG signal that is two times larger that of the α-quartz powder standard and close to other silicates with acentric structures and low electronic polarizability.

  16. Adaptive Federal Kalman Filtering for SINS/GPS Integrated System

    杨勇; 缪玲娟

    2003-01-01

    A new adaptive federal Kalman filter for a strapdown integrated navigation system/global positioning system (SINS/GPS) is given. The developed federal Kalman filter is based on the trace operation of parameters estimation's error covariance matrix and the spectral radius of update measurement noise variance-covariance matrix for the proper choice of the filter weight and hence the filter gain factors. Theoretical analysis and results from simulation in which the SINS/GPS was compared to conventional Kalman filter are presented. Results show that the algorithm of this adaptive federal Kalman filter is simpler than that of the conventional one. Furthermore, it outperforms the conventional Kalman filter when the system is undertaken measurement malfunctions because of its possession of adaptive ability. This filter can be used in the vehicle integrated navigation system.

    Full Text Available A constrained low-cost SINS/OD filter aided with magnetometer is proposed in this paper. The filter is designed to provide a land vehicle navigation solution by fusing the measurements of the microelectromechanical systems based inertial measurement unit (MEMS IMU, the magnetometer (MAG, and the velocity measurement from odometer (OD. First, accelerometer and magnetometer integrated algorithm is studied to stabilize the attitude angle. Next, a SINS/OD/MAG integrated navigation system is designed and simulated, using an adaptive Kalman filter (AKF. It is shown that the accuracy of the integrated navigation system will be implemented to some extent. The field-test shows that the azimuth misalignment angle will diminish to less than 1°. Finally, an outliers detection algorithm is studied to estimate the velocity measurement bias of the odometer. The experimental results show the enhancement in restraining observation outliers that improves the precision of the integrated navigation system.

    After the KamLAND results, the remaining important targets in neutrino experiments are to measure still unknown 3 basic parameters; absolute neutrino mass scale, CP violation phase $\\delta_{CP}$ and last mixing angle $\\theta_{13}$. The angle $\\theta_{13}$ among them is expected to be measured in near future by long baseline accelerator experiments and reactor experiments. In this paper, a realistic idea of high sensitivity reactor measurement of $\\sin^22\\theta_{13}$ is described. This experiment uses a giant nuclear power plant as the neutrino source and three identical detectors are used to cancel detector and neutrino flux uncertainties. The sensitivity reach on $\\sin^22\\theta_{13}$ is $0.017\\sim0.026$ at $\\Delta m^2_{13} \\sim 3 \\times 10^{-3}eV^2$, which is five to seven times better than the current upper limit measured by CHOOZ.

    2016-01-01

    The human immune system has evolved to fight against foreign pathogens. It plays a central role in the body's defense mechanism. However, the immune memory geared to fight off a previously recognized pathogen, tends to remember an original form of the pathogen when a variant form subsequently invades. This has been termed 'original antigenic sin'. This adverse immunological effect can alter vaccine effectiveness and sometimes cause enhanced pathogenicity or additional inflammatory responses, according to the type of pathogen and the circumstances of infection. Here we aim to give a simplified conceptual understanding of virus infection and original antigenic sin by comparing and contrasting the two examples of recurring infections such as influenza and dengue viruses in humans.

  7. Parameter Identification Method for SINS Initial Alignment under Inertial Frame

    Directory of Open Access Journals (Sweden)

    Haijian Xue

    2016-01-01

    Full Text Available The performance of a strapdown inertial navigation system (SINS largely depends on the accuracy and rapidness of the initial alignment. The conventional alignment method with parameter identification has been already applied widely, but it needs to calculate the gyroscope drifts through two-position method; then the time of initial alignment is greatly prolonged. For this issue, a novel self-alignment algorithm by parameter identification method under inertial frame for SINS is proposed in this paper. Firstly, this coarse alignment method using the gravity in the inertial frame as a reference is discussed to overcome the limit of dynamic disturbance on a rocking base and fulfill the requirement for the fine alignment. Secondly, the fine alignment method by parameter identification under inertial frame is formulated. The theoretical analysis results show that the fine alignment model is fully self-aligned with no external reference information and the gyrodrifts can be estimated in real time. The simulation results demonstrate that the proposed method can achieve rapid and highly accurate initial alignment for SINS.

    Snell's law states that the quantity $n\\sin\\theta$ is unchanged in refraction of light passing from one medium to another. We inquire whether this is true in the general case where the speed of light varies continuously within a medium. It turns out to be an instructive exercise in application of Snell's law and Fermat's principle. It also provides good pedagogical problems in calculus of variations to deal with the subtleties of a variable domain of integration and inclusion of constraints. The final result of these exercises is that, contrary to an initial expectation, the answer to the question in the title is negative.

We inquire whether this is true in the general case where the speed of light varies continuously within a medium. It turns out to be an instructive exercise in application of Snell’s law and Fermat’s principle. It also provides good pedagogical problems in calculus of variations to deal with the subtleties of a variable domain of integration and inclusion of constraints. The final result of these exercises is that, contrary to an initial expectation, the answer to the question in the title is negative.

    针对无人机GPS/SINS组合导航系统中航向角误差可观测性差的问题,提出了一种无人机GPS/SINS/Vision组合导航方法.使用无人机搭载的摄像机获取周围景物的图像序列,通过跟踪图像序列中提取的特征点,利用极几何约束获得其间摄像机的位移信息,将测量到的位移信息融合到GPS/SINS组合导航系统中,构成GPS/SINS/Vision组合导航系统.通过观测位置误差、速度误差和摄像机位移在像平面上的投影误差,建立组合导航误差状态卡尔曼滤波器,估计导航系统的误差状态,并根据估计结果对导航系统状态进行修正.推导了滤波器状态方程和测量方程,使用Simulink对算法进行仿真验证,在水平姿态角偏差为10°左右、航向角偏差为20°左右的初始条件下,水平姿态角误差和航向角误差均能快速收敛,水平姿态角误差在10s后收敛到1°左右,航向角误差20s后收敛到2°以内.仿真实验表明,该方法能有效提高无人机姿态角估计的速度和精度.%To solve the problem that observability of yaw error is poor in GPS/SINS integrated navigation system of UAVs (Unmanned Air Vehicles), a GPS/SINS/Vision integrated navigation system is proposed. The camera on board takes a sequence of images. Several feature points are extracted from these images. The direction of camera translation in that period is obtained by tracking these feature points. A GPS/SINS/Vision integrated navigation system is established by including the information of camera translation to GPS/SINS fusion filter. The state error of navigation system is estimated by measuring position error, velocity error and the projection error of camera translation. This approach is realized via a Kalman filter. The UAVs motion state is corrected by using estimation results of Kalman filter. In the end, a simulative experiment is made by using Simulink. Assuming that the initial horizontal attitude error of UAVs is about 10

    Recent time-dependent CP asymmetry measurements in the $B_d \\to J/\\psi K_S$ channel by the BaBar and Belle Collaborations yield somewhat lower values of $\\sin 2\\beta$ compared to the one obtained from the standard model fit. If the inconsistency between these numbers persists with more statistics, this will signal new physics contaminating the $B_d \\to J/\\psi K_S$ channel, thus disturbing the extraction of $\\beta$. We show that the R-parity-violating interactions in supersymmetric theories can provide extra new phases which play a role in significantly reducing the above CP asymmetry, thus explaining why BaBar and Belle report lower values of $\\sin 2\\beta$. The same couplings also affect the $B_d \\to \\phi K_S$ decay rate and asymmetry, explain the $B \\to \\eta' K$ anomaly, and predict nonzero CP asymmetry in dominant $B_s$ decays. The scenario will be tested in the ongoing and upcoming B factories.

    1987-05-01

    Acedia is a term of the classical greek vocabulary that a christian author of the IVth century, Evagre the Pontic, uses in a special sense, to describe a mental state characterized among other things, by disgust and dejection, and which, according to him, falls into what became the first list of deadly sins. The word was conveyed to us by another monk of the egyptian deserts, Jean Cassien, with a change of meaning which made it very difficult to distinguish from sadness: his audience being very different from his predecessor's, as he wrote for Latins, little inclined to anachoretic life but among which developed the first great coenobitic institutions of the Occident. One century later, Pope Gregory the great removes acedia from the list of deadly sins, either because he does not distinguish it from sadness (and laziness) or because he considers it a morbid state and, as such, depending on medical care. The word has nevertheless survived until Thomas Aquinas and later, and its study provides valuable data on the mental states prefiguring our modern depressions.

    With ever changing landscapes and environmental conditions due to human induced climate change, adaptability is imperative for the long-term success of facilities and Federal agency missions. To mitigate the effects of climate change, indicators such as above-ground biomass change must be identified to establish a comprehensive monitoring effort. Researching the varying effects of climate change on ecosystems can provide a scientific framework that will help produce informative, strategic and tactical policies for environmental adaptation. As a proactive approach to climate change mitigation, NASA tasked the Climate Change Adaptation Science Investigators Workgroup (CASI) to provide climate change expertise and data to Center facility managers and planners in order to ensure sustainability based on predictive models and current research. Generation of historical datasets that will be used in an agency-wide effort to establish strategies for climate change mitigation and adaptation at NASA facilities is part of the CASI strategy. Using time series of historical remotely sensed data is well-established means of measuring change over time. CASI investigators have acquired multispectral and hyperspectral optical and LiDAR remotely sensed datasets from NASA Earth Observation Satellites (including the International Space Station), airborne sensors, and astronaut photography using hand held digital cameras to create a historical dataset for the Johnson Space Center, as well as the Houston and Galveston area. The raster imagery within each dataset has been georectified, and the multispectral and hyperspectral imagery has been atmospherically corrected. Using ArcGIS for Server, the CASI-Regional Remote Sensing data has been published as an image service, and can be visualized through a basic web mapping application. Future work will include a customized web mapping application created using a JavaScript Application Programming Interface (API), and inclusion of the CASI data

    We have studied nonisoscalarity and medium effects in the extraction of weak mixing angle using Paschos and Wolfenstein relation in the iron nucleus. Paschos and Wolfenstein(PW) relation is valid for an isoscalar target. We have modified the PW relation for nonisoscalar target as well as incorporated the medium effects like Pauli blocking, Fermi motion, nuclear binding energy and pion rho cloud contributions. In our calculations we have used the relativistic nuclear spectral function which includes nucleon correlations. Finally local density approximation is applied to translate the numerical results to the finite nuclei. We have studied the dependence of $sin^{2}\\theta_W$ on Bjorken variables $x$ and $y$, four momentum transfer square ($Q^2$), energy of the neutrino and antineutrino, and effect of excess neutrons over protons in the nuclear target.

    Sin3 is a transcriptional corepressor for REST silencing machinery that represses multiple neuronal genes in non-neuronal cells. However, functions of Sin3 (Sin3A and Sin3B) in suppression of neuronal phenotypes are not well characterized. Herein we show that Sin3A knockdown impedes the repressive activity of REST and enhances differentiation of pluripotent P19 cells into electrophysiologically active neurons without inducing astrogenesis. It is also found that silencing Sin3B induces neurogenesis of P19 cells with a lower efficiency than Sin3A knockdown. The results suggest that Sin3A has a more profound effect on REST repressive machinery for silencing neuronal genes in P19 cells than Sin3B. Furthermore, we show that a peptide inhibitor of Sin3A-REST interactions promotes differentiation of P19 cells into functional neurons. Observations made in studies using genetic deletion and a synthetic inhibitor suggests that Sin3A plays an important role in the repression of neuronal genes by the REST regulatory mechanism.

    Full Text Available Abstract Background SIN3 is a transcriptional repressor protein known to regulate many genes, including a number of those that encode mitochondrial components. Results By monitoring RNA levels, we find that loss of SIN3 in Drosophila cultured cells results in up-regulation of not only nuclear encoded mitochondrial genes, but also those encoded by the mitochondrial genome. The up-regulation of gene expression is accompanied by a perturbation in ATP levels in SIN3-deficient cells, suggesting that the changes in mitochondrial gene expression result in altered mitochondrial activity. In support of the hypothesis that SIN3 is necessary for normal mitochondrial function, yeast sin3 null mutants exhibit very poor growth on non-fermentable carbon sources and show lower levels of ATP and reduced respiration rates. Conclusions The findings that both yeast and Drosophila SIN3 affect mitochondrial activity suggest an evolutionarily conserved role for SIN3 in the control of cellular energy production.

    In order to enhance the accuracy and reliability of the strap-down inertial navigation system (SINS) and global positioning system (GPS), the principles of SINS and GPS are researched. The state equation of SINS/GPS and the measurement equation of the position velocity error are established; and the SINS/GPS integrated navigation is implemented by adopting Kalman filtering algorithm. The Matlab simulation result proves that this integrated navigation realized by Kalman filtering greatly enhances the accuracy. In addition, the integrated navigation system overcomes the disadvantage of SINS, i.e., hard to operate independently in long period; and solves the problems of GPS, i. e. , easily unlock,and poor real-time control performance; thus the high accuracy and reliability and real-time performance of the navigation system are guaranteed.%为提高捷联惯导系统SINS和全球定位系统GPS的精度和可靠性,研究了SINS和GPS的原理,建立了SINS/GPS系统的状态方程和位置速度误差量测方程;并采用卡尔曼滤波算法实现了SINS/GPS的组合导航.Matlab仿真结果证明,采用Kalman滤波实现SINS/GPS组合导航,其精度得到大大提高;且采用SINS/GPS组合导航系统,克服了SINS惯性导航难以长时间独立工作的缺点,解决了GPS易失锁、难以实时控制的不足,保证了导航系统的实时性及较高的精度和可靠性.

  13. Illness, disease and sin: the connection between genetics and spirituality.

    Science.gov (United States)

    Beck, Matthias

    2007-01-01

    The New Testament, while rejecting any superficial connection between illness and sin, does not reject a possible connection between illness and a person's relationship with God. An example can be seen in the story of the young blind man who was healed (St. John 9:3). His blindness does not result from any fault he or his parents had committed but apparently from God's wish to reveal his own healing power. The inner blindness of the Pharisees is a different type of blindness far more difficult to heal. The blind young man was actually healed, not only in body but also in soul. Such miraculous healings are rare nowadays. However, if one takes a closer look at modern genetics and psycho-neuro-immunological findings, one may come to a better understanding of how miracle healings are linked to man's inner life and therefore also to his religiousness. Many diseases have genetic backgrounds. Defective genes, however, do not necessarily lead to subsequent illness. Genes have to be switched on or off. Only activated genes trigger pathological change. The human brain and all of man's thinking and feeling are intimately connected with such activations. We may thus conclude that both inner life and religious outlook on life are relevant to the origin and development of diseases.

    To solve the problem that the standard Kalman filter cannot give the optimal solution when the system model and stochastic information are unknown accurately,single fading factor Kalman filter is suitable for simple systems.But for complex systems with multi-variable,it may not be sufficient to use single fading factor as a multiplier for the covariance matrices.In this paper,a new multiple fading factors Kalman filtering algorithm is presented.By calculating the unbiased estimate of the innovation sequence covariance using fenestration,the fading factor matrix is obtained.Adjusting the covariance matrix of prediction error Pk|k-1 using fading factor matrix,the algorithm provides different rates of fading for different filter channels.The proposed algorithm is applied to strapdown inertial navigation system(SINS) initial alignment,and simulation and experimental results demonstrate that,the alignment accuracy can be upgraded dramatically when the actual system noise characteristics are different from the pre-set values.The new algorithm is less sensitive to uncertainty noise and has better estimation effect of the parameters.Therefore,it is of significant value in practical applications.

    2014-05-01

    Full Text Available The article attempts to investigate the possible lived experiences created by this text. The text revolves around the experience of fellowship with God (1:6, 7 who is characterised as ‘light’. For the author of 1 John, sin disrupts this fellowship. He creates an awareness and a ‘spirituality of sin and guilt’ in the lives of his readers through the use of the experiential metaphor of darkness in a dialectic combination with light and the two false negations ‘do not have sin’ (sin as a noun and ‘do not sin’ (sin as a verb. This fellowship is re-established through living in the light: the confession, forgiveness and expiation of sin. The author creates a spirituality of confession, forgiveness and expiation of sin through descriptive cultic (blood of Jesus and expiation, forensic (paraclete, atypical (cleans, expiation, paraclete and all-inclusive (all [twice], whole, anyone language. Thus, in his rhetoric, the author uses metaphor, dialectic, sacrificial, forensic, atypical and all-inclusive language to facilitate a variety of ‘lived experiences’ within his readers. Firstly, he wants them to feel guilty about their sins and consequently, after they have confessed their sins, to strengthen their faith. Secondly, he wants to encourage them to believe that they can experience the forgiveness of their sins and, by doing so, know that they have eternal life (5:13 and can experience fellowship with God and, mutually, with one another.

  19. Assessing the consistency of John Calvin’s doctrine on human sinfulness

    Directory of Open Access Journals (Sweden)

    Nico Vorster

    2015-03-01

    Full Text Available The accusation is often levelled at Calvin that his doctrine on sin is inconsistent, contradictory, deterministic and culpable of making God the Author of sin. This article probes the validity of these accusations by analysing the consistency of John Calvin’s doctrine on human sinfulness and by asking whether Calvin’s understanding of sinful human nature is theologically valid. In doing so, the investigation keeps in mind the structural make-up of his theology, the rhetorical intent of his utterances and the devices he employs to harmonise possible inconsistencies in his theology. The finding is that characterisations of Calvin’s doctrine on sin as deterministic, logically inconsistent and culpable of making God the Author of sin are not well-founded. Factors often overlooked are the dialectical nature of his theological reflection on sin, the chronological evolution of his thought on sin and the fact that he does not regard God and human beings as operating on the same ontological level, though this does not mean that God is not active in creaturely reality. When these factors are taken into account, Calvin’s doctrine on sin proves to be fairly consistent and reconcilable with the rest of his theology.

    The paper intends contribute to global warming mitigation joint effort that develops technologies to capture the CO{sub 2} produced by fossil fuels combustion and to reduce emission of other greenhouse gases like the NO{sub x}. After reviewing existing combustion bibliography is pointed out that (a) touches only partial aspects of the collective system composed by Combustion-Heat transfer process-Environment, whose interactions are our primary interest and (b) most specialists think there is not yet a clearly winning technology for CO{sub 2} capture and storage. In this paper the study of combustion is focused as integrated in the aforementioned collective system where application of flameless combustion, using oxidant preheated in heat regenerators and fluent gas recirculation into combustion chamber plus appropriated heat and mass balances, simultaneously results in energy saving and environmental impact reduction. [Spanish] El trabajo pretende contribuir al esfuerzo conjunto de mitigacion del calentamiento global que aporta tecnologias para capturar el CO{sub 2} producido por la combustion de combustibles fosiles y para disminuir la emision de otros gases invernadero como NOx. De revision bibliografica sobre combustion se concluye que (a) trata aspectos parciales del sistema compuesto por combustion-proceso de trasferencia de calor-ambiente, cuyas interacciones son nuestro principal interes (b) la mayoria de especialistas considera no hay todavia una tecnologia claramente superior a las demas para captura y almacenaje de CO{sub 2}. Se estudia la combustion como parte integrante del mencionado sistema conjunto, donde la aplicacion de combustion sin flama, empleando oxidante precalentado mediante regeneradores de calor y recirculacion de gases efluentes ademas de los balances de masa y energia adecuados, permite tener simultaneamente ahorros energeticos e impacto ambiental reducido.

    Today we are in the midst of information and 'total quality' revolutions. At the NASA STI Program's Center for AeroSpace Information (CASI), we are focused on using continuous improvements techniques to enrich today's services and products and to ensure that tomorrow's technology supports the TQM-based improvement of future STI program products and services. The Continuous Improvements Program at CASI is the foundation for Total Quality Management in products and services. The focus is customer-driven; its goal, to identify processes and procedures that can be improved and new technologies that can be integrated with the processes to gain efficiencies, provide effectiveness, and promote customer satisfaction. This Program seeks to establish quality through an iterative defect prevention approach that is based on the incorporation of standards and measurements into the processing cycle. Four projects are described that utilize cross-functional, problem-solving teams for identifying requirements and defining tasks and task standards, management participation, attention to critical processes, and measurable long-term goals. The implementation of these projects provides the customer with measurably improved access to information that is provided through several channels: the NASA STI Database, document requests for microfiche and hardcopy, and the Centralized Help Desk.

    Full Text Available Total thyroidectomy is a surgery that removes all the thyroid tissue from the patient. The suspect of cancer in a thyroid nodule is the most frequent indication and it is presume when previous fine needle puncture is positive or a goiter has significant volume increase or symptomes. Less frequent indications are hyperthyroidism when it is refractory to treatment with Iodine 131 or it is contraindicated, and in cases of symptomatic thyroiditis. The thyroid gland has an important anatomic relation whith the inferior laryngeal nerve and the parathyroid glands, for this reason it is imperative to perform extremely meticulous dissection to recognize each one of these elements and ensure their preservation. It is also essential to maintain strict hemostasis, in order to avoid any postoperative bleeding that could lead to a suffocating neck hematoma, feared complication that represents a surgical emergency and endangers the patient’s life.It is essential to run a formal technique, without skipping steps, and maintain prudence and patience that should rule any surgical act.

  7. Calvin’s modification of Augustine’s doctrine of original sin

    Full Text Available Augustine was Calvin’s main source of reference in the “Insti- tutes”. However, his treatment of Augustine’s views was not uncritical. This article discusses the way in which Calvin modi- fied Augustine’s doctrine of original sin. The main differences can be attributed to different theological aims. Augustine deve- loped his doctrine of original sin against the teachings of the Manicheans and Pelagians, whereas Calvin shifted the focus to knowledge of God and the self. Calvin understood original sin noetically as religious and moral blindness – whereas Augus- tine viewed sexual concupiscence as the main principle of original sin. Augustine made a considerable effort to explain that sin does not find its origin in God. God foresaw the fall, but did not compel it. Calvin located sin in God’s eternal decree and permission. Augustine, furthermore, understood the transmis- sion of original sin biologically, whereas Calvin ascribed it to God’s eternal permissive will. These differences culminated in a different understanding of the meaning of Jesus’ virgin birth. The article concludes by discussing the relevance of Calvin’s noetic approach to original sin.

  8. The Posterior Distribution of sin(i) for Exoplanets with M_T sin(i) Determined from Radial Velocity Data

    CERN Document Server

    Ho, Shirley

    2010-01-01

    Radial velocity (RV) observations of an exoplanet system giving a value of M_T sin(i) condition (ie. give information about) not only the planet's true mass M_T but also the value of sin(i) for that system (where i is the orbital inclination angle). Thus the value of sin(i) for a system with any particular observed value of M_T sin(i) cannot be assumed to be drawn randomly from a distribution corresponding to an isotropic i distribution, i.e. the presumptive prior distribution . Rather, the posterior distribution from which it is drawn depends on the intrinsic distribution of M_T for the exoplanet population being studied. We give a simple Bayesian derivation of this relationship and apply it to several "toy models" for the (currently unknown) intrinsic distribution of M_T. The results show that the effect can be an important one. For example, even for simple power-law distributions of M_T, the median value of sin(i) in an observed RV sample can vary between 0.860 and 0.023 (as compared to the 0.866 value for...

    Full Text Available Federated filter was an important method to estimate high-precision navigation parameters based on “SINS/GPS/CNS”. A no-feedback federated filter with UD_UKF algorithm was designed in the paper, a threetime amendment scheme to correct navigation parameters was designed at the same time and the mathematical model of SINS/GPS/CNS was established in launch inertial coordinate system too. The paper discussed the simulation conditions and a lot of simulations were carried out to compare 2 aspects: (1the performance between four navigation mode, which respectively is SINS, SINS/GPS, SINS/CNS, SINS/GPS/CNS;(2the estimate precision of federated filter and that of centralized Kalman filter. The results of simulation showed that the designed federated filter and amendment scheme based on SINS/GPS/CNS had high estimate precision and led to gain high hitting precision of ballistic missile, that is to say position errors were less than 20 meter and velocity errors were less than 0.1m/s in simulation.

  12. Dma1-dependent degradation of SIN proteins during meiosis in Schizosaccharomyces pombe.

    Krapp, Andrea; Simanis, Viesturs

    2014-07-15

    The Schizosaccharomyces pombe septation initiation network (SIN) is required for cytokinesis during vegetative growth and for spore formation during meiosis. Regulation of the SIN during mitosis has been studied extensively, but less is known about its meiotic regulation. Here, we show that several aspects of SIN regulation differ between mitosis and meiosis. First, the presence of GTP-bound Spg1p is not the main determinant of the timing of Cdc7p and Sid1p association with the spindle pole body (SPB) during meiosis. Second, the localisation dependencies of SIN proteins differ from those in mitotic cells, suggesting a modified functional organisation of the SIN during meiosis. Third, there is stage-specific degradation of SIN components in meiosis; Byr4p is degraded after meiosis I, whereas the degradation of Cdc7p, Cdc11p and Sid4p occurs after the second meiotic division and depends upon the ubiquitin ligase Dma1p. Finally, Dma1p-dependent degradation is not restricted to the SIN, as we show that Dma1p is needed for the degradation of Mcp6p (also known as Hrs1p) during meiosis I. Taken together, these data suggest that stage-specific targeted proteolysis plays an important role in regulating meiotic progression.

    The mechanistic target of rapamycin complex 2 (mTORC2) regulates cell survival and cytoskeletal organization by phosphorylating its AGC kinase substrates; however, little is known about the regulation of mTORC2 itself. It was previously reported that Akt phosphorylates the mTORC2 subunit SIN1 at T86, activating mTORC2 through a positive feedback loop, though another study reported that S6K phosphorylates SIN1 at the same site, inhibiting mTORC2 activity.

    Aiming at Double-Star positioning system's shortcomings of delayed position information and easy exposition of the user as well as the error increase of the SINS with the accumulation of time, the integration of Double-Star positioning system and the SINS is one of the developing directions for an integrated navigation sys-tem. This paper puts forward an optimal predication method of Double-Star/SINS integrated system based on discrete integration, which can make use of the delayed position information of Double-Star positioning system to optimally predicate the integrated system, and then corrects the SINS. The experimental results show that this method can increase the user's concealment under the condition of assuring the system's accuracy.

    To realize dynamic positioning of the shearer, a new method based on SINS/WSN is studied in this paper. Firstly, the shearer movement model is built and running regularity of the shearer in coal mining face has been mastered. Secondly, as external calibration of SINS using GPS is infeasible in enclosed underground mine, WSN positioning strategy is proposed to eliminate accumulative error produced by SINS; then the corresponding coupling model is established. Finally, positioning performance is analyzed by simulation and experiment. Results show that attitude angle and position of the shearer can be real-timely tracked by integrated positioning strategy based on SINS/WSN, and positioning precision meet the demand of actual working condition.

SINS/GPS ( strapdown inertial navigation system/global positioning system) integrated navigation system can not meet the need of UAV navigation accuracy and stability in long time because GPS signal is susceptible to interference. Based on the analysis of the characteristics of air data system,the SINS/ADS (air data system) error model is derived based on the attitude and airspeed information provided by pressure sensors,and the SINS/ADS measurement equation is established. The SINS/ GPS integrated navigation system assisted by air data system is designed. Aiming at the output frequency inconsistency between GPS and ADS,an asynchronous centralized Kalman filter is designed for separating the time update period and measurement update period. Actual operation experiments on vehicle confirm that the designed system can effectively improve the accuracy and stability of the system under interference condition,and the positioning accuracy can reach 25 m.

    Quorum sensing (QS) in Sinorhizobium meliloti, the N-fixing bacterial symbiont of Medicago host plants, involves at least half a dozen different N-acyl homoserine lactone (AHL) signals and perhaps an equal number of AHL receptors. The accumulation of 55 proteins was found to be dependent on SinI, the AHL synthase, and/or on ExpR, one of the AHL receptors. Gas chromatography-mass spectrometry and electrospray ionization tandem mass spectrometry identified 3-oxo-C(14)-homoserine lactone (3-oxo-C(14)-HSL), C(16)-HSL, 3-oxo-C(16)-HSL, C(16:1)-HSL, and 3-oxo-C(16:1)-HSL as the sinI-dependent AHL QS signals accumulated by the 8530 expR(+) strain under the conditions used for proteome analysis. The 8530 expR(+) strain secretes additional, unidentified QS-active compounds. Addition of 200 nM C(14)-HSL or C(16:1)-HSL, two of the known SinI AHLs, affected the levels of 75% of the proteins, confirming that their accumulation is QS regulated. A number of the QS-regulated proteins have functions plausibly related to symbiotic interactions with the host, including ExpE6, IdhA, MocB, Gor, PckA, LeuC, and AglE. Seven of 10 single-crossover beta-glucuronidase (GUS) transcriptional reporters in genes corresponding to QS-regulated proteins showed significantly different activities in the sinI and expR mutant backgrounds and in response to added SinI AHLs. The sinI mutant and several of the single-crossover strains were significantly delayed in the ability to initiate nodules on the primary root of the host plant, Medicago truncatula, indicating that sinI-dependent QS regulation and QS-regulated proteins contribute importantly to the rate or efficiency of nodule initiation. The sinI and expR mutants were also defective in surface swarming motility. The sinI mutant was restored to normal swarming by 5 nM C(16:1)-HSL.

    Eukaryotic genes are typically interrupted by intragenic, noncoding sequences termed introns. However, some genes lack introns in their coding sequence (CDS) and are generally known as 'single exon genes' (SEGs). In this work, a SEG is defined as a nuclear, protein-coding gene that lacks introns in its CDS. Whereas, many public databases of Eukaryotic multi-exon genes are available, there are only two specialized databases for SEGs. The present work addresses the need for a more extensive and diverse database by creating SinEx DB, a publicly available, searchable database of predicted SEGs from 10 completely sequenced mammalian genomes including human. SinEx DB houses the DNA and protein sequence information of these SEGs and includes their functional predictions (KOG) and the relative distribution of these functions within species. The information is stored in a relational database built with My SQL Server 5.1.33 and the complete dataset of SEG sequences and their functional predictions are available for downloading. SinEx DB can be interrogated by: (i) a browsable phylogenetic schema, (ii) carrying out BLAST searches to the in-house SinEx DB of SEGs and (iii) via an advanced search mode in which the database can be searched by key words and any combination of searches by species and predicted functions. SinEx DB provides a rich source of information for advancing our understanding of the evolution and function of SEGs.Database URL: www.sinex.cl.

    Full Text Available The mechanistic target of rapamycin complex 2 (mTORC2 regulates cell survival and cytoskeletal organization by phosphorylating its AGC kinase substrates; however, little is known about the regulation of mTORC2 itself. It was previously reported that Akt phosphorylates the mTORC2 subunit SIN1 at T86, activating mTORC2 through a positive feedback loop, though another study reported that S6K phosphorylates SIN1 at the same site, inhibiting mTORC2 activity. We performed extensive analysis of SIN1 phosphorylation upon inhibition of Akt, S6K, and mTOR under diverse cellular contexts, and we found that, in all cell lines and conditions studied, Akt is the major kinase responsible for SIN1 phosphorylation. These findings refine the activation mechanism of the Akt-mTORC2 signaling branch as follows: PDK1 phosphorylates Akt at T308, increasing Akt kinase activity. Akt phosphorylates SIN1 at T86, enhancing mTORC2 kinase activity, which leads to phosphorylation of Akt S473 by mTORC2, thereby catalyzing full activation of Akt.

An unambiguous structure of the Si12+ cluster is presented, whose IR spectrum agrees well with the experiment result. The most stable geometric structures of Ge+n(n=2-15) clusters were determined by the all-electron PBE/DND method in DMol3 of the Material Studio Package, and compared with those of the corresponding Si+n geometries. Most structures of Ge+n and Si+n are similar except the ones of those for n=9, 12, 13 and 14, and the pentagonal bipyramid motif and the tri-capped trigonal prism(TTP) motif often appear in the Si+n and Ge+n(n=7-15) structures(except for Si14+).

    Full Text Available La consigna "pensar el sexo sin ley, y el poder sin el rey" formulada a modo de divisa por M. Foucault en Histoire de la sexualité I, La volonté de savoir, puede ser interpretada como clave de inteligibilidad del decurso genealógico que lleva adelante el autor desde mediados de la década del ´70, hasta desembocar en la formulación ontológica esbozada en sus últimos escritos. En este artículo se pretende dar cuenta, tanto de los desplazamientos operados por mor de la aplicación de tal consigna en la perspectiva de análisis de las relaciones de poder, como de la concepción de la subjetividad. El objetivo de la autora es doble: identificar y caracterizar una forma de ejercicio del poder fuera del modelo jurídico de soberanía, y establecer el carácter y la condición de una subjetividad constituida sin recurso a una legalidad.The maxim "think sex without law, and power without the king" formulated as an emblem by M. Foucault in Histoire de la sexualité I, La volonté de savoir, may be interpreted as key of intelligibility of the genealogical development carried forward by the author since the mid- seventies, which ends up in the ontological formulation sketched out in his last writings. This article seeks to account for the displacements operated by the application of such maxim from the perspective of the analysis of power relations, as well as for the conception of subjectivity. The aim of the article is twofold: to identify and characterize a form of exercising power at a remove from the juridical model of sovereignty, and to establish the character and condition of a subjectivity constituted without resort to any legality.

    2013-05-01

    Full Text Available In many animals, a fast and reliable circuit for discriminating between predator-sized objects and edible (prey-sized objects is necessary for survival. How are receptive fields in visual brain areas organized to extract information about size? Recent studies from the zebrafish optic tectum and the mouse visual cortex suggest de novo shaping of receptive fields by subtypes of inhibitory neurons. Del Bene et al. (2010 describe a population of GABAergic neurons in the zebrafish optic tectum (Superficial Interneurons, SINs that are necessary for size filtering during prey capture. Adesnik et al. (2012 describe a somatostatin-expressing interneuron population (SOMs that confers surround suppression on layer II/III pyramidal cells in mouse V1. Strikingly both the SINs and the SOMs, display size-dependent response properties. Increasing visual stimulus size increases excitatory input to these neurons. Dampening SIN or SOM activity alters tuning of neighboring circuits such that they lose preference for small objects. Both results provide exciting evidence for mechanisms of size filtering in visual circuits. Here we review the roles of the SINs and the SOMs and speculate on the similarity of such spatial filters across species.

Este costo mayor estuvo relacionado con el precio del estabilizador descartable, que es comparativamente más caro que el de un oxigenador. Así, proporcionalmente, el costo total de quirófano de una cirugía sin CEC fue el 15% a 39% más caro que la cirugía convencional. Por su parte, el análisis del costo de una cirugía, teniendo en cuenta las tasas de complicaciones, mostró valores entre $11.978 y $18.145 (mediana: $14.350 para la cirugía sin CEC, y entre $12.303 y $16.518 (mediana: $13.377 para el procedimiento “con bomba”. Conclusiones En el presente estudio no se ha podido demostrar una reducción del costo de la cirugía coronaria con el empleo de la técnica de revascularización sin CEC, al compararla con el procedimiento convencional. El precio de los insumos de quirófano (estabilizador coronario parece ser el factor determinante del alto costo de la cirugía sin CEC en la Argentina. Medidas regulativas que contemplen la reutilización de los estabilizadores coronarios descartables o una política que favorezca la reducción del costo de los insumos quirúrgicos podrían mejorar la relación costo-eficacia de la cirugía “sin bomba” en nuestro medio.

    空天飞行器往返于大气层内外,持续工作时间长。捷联惯性/天文组合导航自主性强、隐蔽性好,是最适合空天飞行器的导航方式之一。为提高传统天文定位的导航精度和可靠性,解决其在机载应用中水平基准制约的问题,分析了平台误差角和位置误差对高度角量测的影响,提出了一种以天体高度角为量测信息的捷联惯性/天文深组合导航算法。该算法采用卡尔曼滤波器进行最优估计,可有效估计并补偿系统的姿态误差,减少天文导航定位对水平基准的依赖。仿真表明,单星观测条件下,导航系统姿态误差快速收敛,定位的均方根误差在200 m以内,且系统导航性能随导航星数量的增加而提高。%Aerospace vehicles usually work both inside and outside the Earth’s atmosphere for long-range missions, and strap-down inertial navigation system (SINS) / celestial navigation system (CNS) integrated navigation method has been considered as an appropriate navigation solution for aerospace vehicles due to its autonomous and concealment capabilities. In order to overcome the limitation of horizontal reference in CNS and improve its accuracy and reliability, this paper analyzes the influence of platform error angles and positioning errors on altitude angle measurement, and proposes a novel algorithm for SINS/CNS tightly integrated navigation based on measured altitudes of celestial bodies. Kalman filter is utilized in this approach in order to effectively compensate attitude errors of SINS and reduce the dependence on horizon reference in CNS. Simulation result demonstrates that the convergence of attitude errors is rapid when single navigational star is observed, and the estimated root mean square positioning error (RMSE) is within 200 m. It also shows that more navigational stars will improve system navigation performance.

    Full Text Available Memory studies in Uruguay are mostly based on testimonies and interpretations of the victims of State terrorism. Instead, our approach will underline the “frozen memory” of the National Party regarding some recent historical issues – inter alia the Pact of the Navy Club and the 1984 national elections – during the Parliamentary approval of the Ley de Caducidad de la Pretensión Punitiva del Estado, which basically pardoned the army for their crimes. The law was proposed and supported by the National Party in 1986. This frozen memory was fully maintained during the two attempts to cancel the law, in April and October 2011. The purpose of this article is to show and evaluate this particular process.

    Full Text Available In airborne MEMS SINS transfer alignment, the error of MEMS IMU is highly environment-dependent and the parameters of the system model are also uncertain, which may lead to large error and bad convergence of the Kalman filter. In order to solve this problem, an improved adaptive incremental Kalman filter (AIKF algorithm is proposed. First, the model of SINS transfer alignment is defined based on the “Velocity and Attitude” matching method. Then the detailed algorithm progress of AIKF and its recurrence formulas are presented. The performance and calculation amount of AKF and AIKF are also compared. Finally, a simulation test is designed to verify the accuracy and the rapidity of the AIKF algorithm by comparing it with KF and AKF. The results show that the AIKF algorithm has better estimation accuracy and shorter convergence time, especially for the bias of the gyroscope and the accelerometer, which can meet the accuracy and rapidity requirement of transfer alignment.

    This paper studies an underwater positioning algorithm based on the interactive assistance of a strapdown inertial navigation system (SINS) and LBL, and this algorithm mainly includes an optimal correlation algorithm with aided tracking of an SINS/Doppler velocity log (DVL)/magnetic compass pilot (MCP), a three-dimensional TDOA positioning algorithm of Taylor series expansion and a multi-sensor information fusion algorithm. The final simulation results show that compared to traditional underwater positioning algorithms, this scheme can not only directly correct accumulative errors caused by a dead reckoning algorithm, but also solves the problem of ambiguous correlation peaks caused by multipath transmission of underwater acoustic signals. The proposed method can calibrate the accumulative error of the AUV position more directly and effectively, which prolongs the underwater operating duration of the AUV.

    We calculate ~\\sin^2\\theta(M_Z) ~in the MSSM in terms of ~ \\alpha_{EM}, ~G_F, ~m_t, ~\\tan\\beta ~and SUSY mass parameters with the same accuracy as the present calculations of ~\\sin^2\\theta(M_Z) ~in the SM. We compare the results with the standard leading logarithmic approximation used for SUSY threshold corrections and find important differences in the case of light sparticles. We give approximate formulae connecting coupling constants in the SM and in the MSSM and comment on process dependence of such formulae. The obtained values of the MSSM couplings ~\\alpha_i(M_Z) ~are used to investigate gauge coupling unification in the minimal SUSY ~SU(5) ~model. Our non-logarithmic corrections lower the predicted value of the Higgs triplet mass. The interplay between the supersymmetric and GUT thresholds in achieving unification for the coupling constants in the range of the experimentally acceptable values is quantified.

Mediante una clasificación supervisada de imágenes de satélite Landsat de 1990, 2000 y 2010, se obtuvieron mapas de cobertura arbolada/condición no-arbolada. Se realizaron cruces de mapas de 1990-2000 y 2000-2010, para obtener mapas de procesos de cambio (deforestación y revegetación y tasas anuales de cambio. En el conjunto de comunidades la cobertura arbolada fue de alrededor del 90% en las tres décadas, pero hubieron diferencias significativas en la cobertura arbolada de las comunidades con-ACPC y sin-ACPC. En las primeras hubo mayor superficie arbolada, menor permanencia de la condición no-arbolada y tasas de cambio relativamente menores. En las comunidades sin- ACPC hubo mayor revegetación entre 2000-2010, pero la recuperación de cobertura no parece ser intencional, ya que las comunidades carecen de acciones para cuidar el bosque. Las comunidades con-ACPC cuentan con asesores y en ellas se hacen investigaciones por parte de académicos y operan programas gubernamentales y no-gubernamentales, pero no es así en las comunidades sin-ACPC. Entender mejor la dinámica de bosques de alto valor ecológico en predios de propiedad social, como los del norte del estado de Oaxaca, es fundamental para orientar mejor políticas públicas enfocadas a atender los bosques a la escala local.

  10. INVESTIGATION OF TIGHTLY COUPLED SINS/GPS INTEGRATION MIDCOURSE GUIDANCE FOR AIR-TO-AIR MISSILES

    Institute of Scientific and Technical Information of China (English)

    1998-01-01

    The applied problems of SINS/GPS integration navigation system existing in midcourse guidance of air-to-air missiles have been investigated recently. In comparison with those investigations existing in current publications, a new tightly coupled SINS/GPS integration navigation system for air-to-air missiles, based on the decorrelated pseudo-range approach, is presented in this paper. Because of high jamming and dynamic of air-to-air missiles, inertial velocity aiding GPS receiver is used to provide a more accurate, jam-resistant measurement for midcourse guidance systems. A tracking error estimator is designed to distinguish the correlation that existed between pseudo-range measurements and inertial information. It is found better to regard inertial velocity aiding errors as the noise of which statistical properties are unknown. So using mixed Kalman/minimax filtering theory, one can obtain the new tracking error estimator with simple and robust algorithm through constructing a composite filter consisting of two parts: Kalman filter for the noise of known statistics and minimax filter for the unknown. In order to ensure this simple estimator stability, a new method is proposed to choose its parameters, based on Khargonekars work. Moreover, it is demonstrated that the given method also ensures the proposed estimator optimality. All the work mentioned above is involved in the tightly coupled SINS/GPS integration midcourse system design in which a set of low-accuracy inertial components is shared by SINS and autopilot. Simulation results of a certain type of air-to-air missile are presented. Due to decorrelation by the tracking error estimator, only small white noise of pseudo-range measurements remains. So it is shown that application of the new midcourse guidance system results in better guidance accuracy, higher jam-resistance.

With the proposed mechanism, a nonlinear SINS error model is presented and the measurement model is derived under the assumption that large misalignments may exist.

Experimental results show that the proposed DVL-aided alignment model is effective with any initial heading errors. The performances of the adaptive filtering methods are evaluated with regards to their parameter estimation stability. Furthermore, it is clearly shown that the measurement noise covariance can be estimated reliably by the adaptive UKF methods and hence improve the performance of the alignment.

  2. RNase E affects the expression of the acyl-homoserine lactone synthase gene sinI in Sinorhizobium meliloti.

    2014-04-01

    Quorum sensing of Sinorhizobium meliloti relies on N-acyl-homoserine lactones (AHLs) as autoinducers. AHL production increases at high population density, and this depends on the AHL synthase SinI and two transcriptional regulators, SinR and ExpR. Our study demonstrates that ectopic expression of the gene rne, coding for RNase E, an endoribonuclease that is probably essential for growth, prevents the accumulation of AHLs at detectable levels. The ectopic rne expression led to a higher level of rne mRNA and a lower level of sinI mRNA independently of the presence of ExpR, the AHL receptor, and AHLs. In line with this, IPTG (isopropyl-β-D-thiogalactopyranoside)-induced overexpression of rne resulted in a shorter half-life of sinI mRNA and a strong reduction of AHL accumulation. Moreover, using translational sinI-egfp fusions, we found that sinI expression is specifically decreased upon induced overexpression of rne, independently of the presence of the global posttranscriptional regulator Hfq. The 28-nucleotide 5' untranslated region (UTR) of sinI mRNA was sufficient for this effect. Random amplification of 5' cDNA ends (5'-RACE) analyses revealed a potential RNase E cleavage site at position +24 between the Shine-Dalgarno site and the translation start site. We postulate therefore that RNase E-dependent degradation of sinI mRNA from the 5' end is one of the steps mediating a high turnover of sinI mRNA, which allows the Sin quorum-sensing system to respond rapidly to changes in transcriptional control of AHL production.

Materiale e metodi: Sono giunti alla nostra osservazione 6 pazienti affetti da pseudo-ostruzione del colon nel periodo compreso tra ottobre 1997 e settembre 2002. In 2 casi la pseudo-ostruzione era recidiva. La positivit� dei reperti radiologici per la dilatazione acuta del colon senza ostruzione organica � stato il criterio di inclusione. Risultati: L'esame diretto dell'addome ha evidenziato che la dilatazione del colon era situata in 3 pazienti fino al livello della flessura splenica, in 2 fino alla flessura epatica e in un caso era interessato unicamente il colon trasverso. Nessuno dei pazienti presentava livelli idroaerei del piccolo intestino. Conclusioni: Il reperto clinico pi� caratteristico della sindrome di Ogilvie � la distensione addominale, che generalmente insorge all'improvviso, ha un'andamento progressivo, e raggiunge gradi elevati. L'indagine diagnostica di prima istanza � l'esame radiografico dell'addome, che documenta la dilatazione estrema del colon, in assenza di livelli idroaerei del tenue. Nella nostra casistica in 3 pazienti la sola terapia conservativa ha permesso il ritorno alla normalit� in 5 giorni. In altri 2 pazienti � stato necessario intervenire con una colonscopia decompressiva. in 1 caso la paziente � deceduta dopo 48 ore per arresto cardiocircolatorio.

    The target of rapamycin (TOR) protein kinase forms multi-subunit TOR complex 1 (TORC1) and TOR complex 2 (TORC2), which exhibit distinct substrate specificities. Sin1 is one of the TORC2-specific subunit essential for phosphorylation and activation of certain AGC-family kinases. Here, we show that Sin1 is dispensable for the catalytic activity of TORC2, but its conserved region in the middle (Sin1CRIM) forms a discrete domain that specifically binds the TORC2 substrate kinases. Sin1CRIM fused to a different TORC2 subunit can recruit the TORC2 substrate Gad8 for phosphorylation even in the sin1 null mutant of fission yeast. The solution structure of Sin1CRIM shows a ubiquitin-like fold with a characteristic acidic loop, which is essential for interaction with the TORC2 substrates. The specific substrate-recognition function is conserved in human Sin1CRIM, which may represent a potential target for novel anticancer drugs that prevent activation of the mTORC2 substrates such as AKT.

    Seismic interferometry is a technique for extracting deterministic signals (i.e., ambient-noise Green's functions) from recordings of ambient-noise wavefields through cross-correlation and other related signal processing techniques. The extracted ambient-noise Green's functions can be used in ambient-noise tomography for constructing seismic structure models of the Earth's interior. The amount of calculations involved in the seismic interferometry procedure can be significant, especially for ambient-noise datasets collected by large seismic sensor arrays (i.e., "large-N" data). We present an efficient parallel algorithm, named pSIN (Parallel Seismic INterferometry), for solving seismic interferometry problems on conventional distributed-memory computer clusters. The design of the algorithm is based on a two-dimensional partition of the ambient-noise data recorded by a seismic sensor array. We pay special attention to the balance of the computational load, inter-process communication overhead and memory usage across all MPI processes and we minimize the total number of I/O operations. We have tested the algorithm using a real ambient-noise dataset and obtained a significant amount of savings in processing time. Scaling tests have shown excellent strong scalability from 80 cores to over 2000 cores.

    When SINS (strap-down inertial navigation system) is combined with GPS, the observability of the course angle is weak. Although the course angle error is improved to some extent through Kalman filtering, the course angle still assumes a divergent trend. This trend is aggravated further when using low-cost and low-accuracy SINS. In order to restrain this trend, a method that uses AHRS to substitute for SINS course angle information is put forward aimed at the hardware component characteristic of the low-cost and low-accuracy SINS including AHRS (attitude and heading reference system) and IMU (inertial measurement unit). Real static and dynamic experiments show that the method can restrain the divergent trend of the navigation system angle effectively, and the positioning accuracy is high.

    Full Text Available The accurate reconstruction of sea surface temperature (SST history in climate-sensitive regions (e.g. tropical and polar oceans became a challenging task in palaeoceanographic research. Biogenic shell carbonate SST proxies successfully developed for tropical regions often fail in cool water environments. Their major regional shortcomings and the cryptic diversity now found within the major high latitude proxy carrier Neogloboquadrina pachyderma (sin. highlight an urgent need to explore complementary SST proxies for these cool-water regions. Here we incorporate the genetic component into a calibration study of a new SST proxy for the high latitudes. We found that the calcium isotopic composition (δ44/40Ca of calcite from genotyped net catches and core-top samples of the planktonic foraminifera Neogloboquadrina pachyderma (sin. is related to temperature and unaffected by genetic variations. The temperature sensitivity has been found to be 0.17 (±0.02‰ per 1°C, highlighting its potential for downcore applications in open marine cool-water environments. Our results further indicate that in extreme polar environments, below a critical threshold temperature of 2.0 (±0.5°C associated with salinities below 33.0 (±0.5‰, a prominent shift in biomineralization affects the δ44/40Ca of genotyped and core-top N. pachyderma (sin., becoming insensitive to temperature. These findings highlight the need of more systematic calibration studies on single planktonic foraminiferal species in order to unravel species-specific factors influencing the temperature sensitivity of Ca isotope fractionation and to validate the proxies' applicability.

  13. A measurement of sin2 2theta13 with the Double Chooz experiment

    Science.gov (United States)

    Crum, Keith Alan

    The observation of neutrino flavor oscillations provided the first definitive evidence of nonzero neutrino masses and cross-generational mixing in the lepton sector of the Standard Model. Flavor oscillations are characterized by three mixing angles---theta12, theta13, and theta23---as well as two neutrino mass squared differences and three possible CP-violating phases. The Double Chooz experiment was designed to measure the final unmeasured mixing angle theta13 by observing the energy-dependent "disappearance" of electron antineutrinos as they oscillate into the other flavor states. The Double Chooz experiment detects electron antineutrinos in gadolinium-doped liquid scintillator after they interact with a proton via inverse beta decay, yielding a positron that is detected promptly and a neutron that is captured later, either by gadolinium or hydrogen. Separate measurements of theta13 were performed by the Double Chooz collaboration for neutrons which captured on gadolinium and those which captured on hydrogen. This dissertation presents the most recent results of a gadolinium-capture analysis, which used 467.90 live-days of data. Performing a fit to the inverse beta decay positron spectrum, we measured sin 2(2theta13) = 0.090-0.029+0.032 with chi2/d.o.f. = 52.2/40 for the normal neutrino mass hierarchy (Deltam2_ee = (2.44 -0.10 +0.09) * 10. -3eV2). Assuming an inverted neutrino mass hierarchy (Delta m2ee = (2.38-0.10 +0.09) * 10-3 eV2), we find sin2(2theta13) = 0.092-0.029 +0.033 with chi2/d.o.f. = 52.2/40. Additional rate-based measurements of sin2(2theta13) were also performed. These results are in agreement with other reactor theta 13 experiments and represent the most precise measurement of theta 13 at Double Chooz to date.

    The insertion of carbene ligands into Ge-N (three examples) and Si-N (one example) bonds has been achieved for the first time by treating Fischer carbene complexes (M = W, Cr) with bulky amidinatotetrylenes (E = Ge, Si). These reactions, which start with a nucleophilic attack of the amidinatotetrylene heavier group-14 atom to the carbene C atom, proceed through a stereoselective insertion of the carbene fragment into an E-N bond of the amidinatotetrylene ENCN four-membered ring, leading to [M(CO)5L] derivatives in which L belongs to a novel family of tetrylene ligands comprising an ECNCN five-membered ring.

    YANG Yong; MIAO Ling-juan; SHEN Jun

    2005-01-01

    A method of improving the navigation accuracy of strapdown inertial navigation system (SINS) is studied. The particular technique discussed involves the continuous rotation of gyros and accelerometers cluster about the vertical axis of the vehicle. Then the errors of these sensors will have periodic variation corresponding to components along the body frame. Under this condition, the modulated sensor errors produce reduced system errors. Theoretical analysis based on a new coordinate system defined as sensing frame and test results are presented, and they indicate the method attenuates the navigation errors brought by the gyros' random constant drift and the accelerometer's bias and their white noise compared to the conventional method.

    Full Text Available From a traditional perspective of Law, the production of legal rules is limited to State powers (legislative, executive and judiciary as well as to some social agents legitimated through mechanisms of social participation foreseen in the legal system. The regulatory capacity of agents not recognized as subjects of legality can only be investigated from a sociological perspective of alternativity of Law. This paper draws attention on acts of migrants, especially those irregular immigrants or “sin-papeles” as subjects of legality. Starting with an analysis of the social, legal and political context of the sit-ins and other acts of mobilization that took place in 2001, we will investigate the capacity of the sin-papeles movement in Barcelona to influence legal production either by creating, modifying or altering the policy agenda on migration.Desde un punto de vista formalista del Derecho, la producción de normas jurídicas está limitada a los poderes del Estado (legislativo, ejecutivo y judicial así como a algunos agentes sociales legitimados por mecanismos de participación previstos en el ordenamiento jurídico. La capacidad normativa de agentes no reconocidos como sujetos de juridicidad únicamente puede ser investigada desde una perspectiva sociológica de la alternatividad del Derecho. Este texto presta atención a los actos de migrantes como sujetos de juridicidad, y especialmente a aquellos construidos social y normativamente como irregulares o autodefinidos como “sin-papeles”. A partir de la descripción de circunstancias sociales, jurídicas y políticas en torno a los encierros y otros actos de movilización que tuvieron lugar en el año 2001, se pretende analizar cuál fue la capacidad de los sin-papeles para incidir en la producción legal ya sea creando, modificando o alterando la agenda normativa en materia migratoria.

El objetivo del estudio fue analizar si la presencia de drenado peritoneal turbio se corresponde con la presencia de infección peritoneal. Se realizó un estudio observacional prospectivo entre Diciembre de 2014 y Marzo de 2015, en el que se incluyeron pacientes con insuficiencia cardiaca refractaria. Se analizaron 4 muestras de cada paciente, separadas por 15 días, de forma programada. Los cultivos bacteriológicos se realizaron en las muestras que presentaban un recuento leucocitario superior a 100 leucocitos/μl. Se recogieron datos epidemiológicos y clínicos de los pacientes, como la patología de base responsable de la insuficiencia cardiaca y las proteínas presentes en el efluente peritoneal. Se evaluaron 13 pacientes, 77% varones, edad media de 71±8 años. Se recogieron un total de 51 muestras; de ellas, en 5 muestras (9.8% procedentes de 4 pacientes (31% del total de pacientes, el efluente peritoneal era turbio.

    Full Text Available Las decisiones de otorgamiento de crédito son cruciales en la administración de riesgos. Las instituciones financieras han desarrollado y usado modelos de credit scoring para estandarizar y automatizar las decisiones de crédito, sin embargo, no es común encontrar metodologías para aplicarlos a clientes sin referencias crediticias, es decir clientes que carecen de información en los burós nacionales de crédito. En este trabajo se presenta una metodología general para construir un modelo sencillo de credit scoring enfocado justamente a esa población, la cual ha venido tomando una mayor importancia en el sector crediticio latinoamericano. Se usa la información sociodemográfica proveniente de las solicitudes de crédito de una pequeña institución bancaria mexicana para ejemplificar la metodología.

    Full Text Available In March 2015, a ground vehicle gravimetry test was implemented in eastern Changsha to assess the repeatability and accuracy of ground vehicle SINS/GNSS gravimeter—SGA-WZ02. The gravity system developed by NUDT consisted of a Strapdown Inertial Navigation System (SINS, a Global Navigation Satellite System (GNSS remote station on test vehicle, a GNSS static master station on the ground, and a data logging subsystem. A south-north profile of 35 km along the highway in eastern Changsha was chosen and four repeated available measure lines were obtained. The average speed of a vehicle is 40 km/h. To assess the external ground gravity disturbances, precise ground gravity data was built by CG-5 precise gravimeter as the reference. Under relative smooth conditions, internal accuracy among repeated lines shows an average agreement at the level of 1.86 mGal for half wavelengths about 1.1 km, and 1.22 mGal for 1.7 km. The root-mean-square (RMS of difference between calculated gravity data and reference data is about 2.27 mGal/1.1 km, and 1.74 mGal/1.7 km. Not all of the noises caused by vehicle itself and experiments environments were eliminated in the primary results. By means of selecting reasonable filters and improving the GNSS observation conditions, further developments in ground vehicle gravimetry are promising.

    Nanoalloy clusters formed between Au and Si are topics of great interest today from both scientific and technological point of view. Due to its remarkable catalytic, electronic, mechanical and magnetic properties Au-Si nanoalloy clusters have extensive applications in the field of microelectronics, catalysis, biomedicine, and jewelry industry. Density Functional Theory (DFT) is a new paradigm of quantum mechanics, which is very much popular to study the electronic properties of materials. Conceptual DFT based descriptors have been invoked to correlate the experimental properties of nanoalloy clusters. In this venture, we have systematically investigated AuSin (n=1-9) nanoalloy clusters in the theoretical frame of the B3LYP exchange correlation. The experimental properties of AuSin (n=1-9) nanoalloy clusters are correlated in terms of DFT based descriptors viz. HOMO-LUMO gap, Electronegativity (χ), Global Hardness (η), Global Softness (S) and Electrophilicity Index (ω). The calculated HOMO-LUMO gap exhibits interesting odd-even alteration behaviour, indicating that even numbered clusters possess higher stability as compare to their neighbour odd numbered clusters. This study also reflects a very well agreement between experimental bond length and computed data.

  6. From Sin to Crime: Laws on Infanticide in the Middle Ages.

    2016-01-01

    This is the second of three papers investigating the legislative history concerning infanticide. It compares the efforts of various states to protect the newborn infant between 534 and 1532 CE. When the Roman Empire collapsed in the 5th century, the jurisdiction of infanticide was relegated to the church, which regarded carnal delicts a sin rather than a crime. The punishment - public penance of the mother for 7-15 years - was milder than that which the murder of an adult would incur. The Council of Florence decreed in 1439 that the souls of children who died without having been baptized descend to hell. This turned infanticide from a penitential sin to the most heinous of all crimes. The states passed laws that abominated infanticide even more than the murder of older humans and punished women with ever more cruel forms of execution. Towards the men, however, who usually abandoned the women they had impregnated, the laws were lenient. Churches and society continued to vilify illegitimate birth, thus enhancing rather than preventing infanticide. The Habsburg-German legislation of 1532 ordained to torture any woman who had concealed pregnancy and birth and claimed the infant was stillborn. Legislation developed similarly in other countries, albeit at a different speed. French (1556) and British (1623) legislation reversed the burden of proof and demanded the death penalty for concealing pregnancy and birth when a dead infant was found.

    Full Text Available Jorge Artel enfrenta su mundo contradictorio y escindido en Sinú, riberas de asombro jubiloso con la propuesta de un idilio, de la recuperación de un paraíso perdido o a punto de perderse. La transgresión del tiempo histórico permite la recuperación de un espaciotiempo primigenio que, convertido en signo, se constituye en fundamento de su identidad. Inicialmente revisamos los enfoques generales teóricos sobre el idilio para luego analizar el largo poema de Artel donde encontramos que a pesar de la exaltación idílica, el poema ofrece una reivindicación social y étnica propia de su corpus literario. Jorge Artel confronts his contradictory and divided World in Sinú, riberas de asombro jubiloso with the proposal of an idyll based on the ideal of recovery of a paradise that has been lost or is in the brink of extinction. The rupture with the chronological and historical time allows the recovery of primeval space-time coordinates which transformed in sign, forms the building blocks of his identity. We began revising the general theoretical principles on idyllic works to later analyze Artel’s long poem where we find that spite of its idyllic exaltation, offers a strong social and ethnic vindication in consonance with his literary corpus.

    To solve the problem of information fusion in the strapdown inertial navigation system(SINS)/celestial navigation system(CNS)/global positioning system(GPS)integrated navigation system described by the nonlinear/non-Gaussian error models,a new algorithm called the federated unscented particle filtering(FUPF)algorithm was introduced.In this algorithm,the unscented particle filter(UPF)served as the local filter,the federated filter was used to fuse outputs of all local filters,and the global filter result was obtained.Because the algorithm was not confined to the assumption of Gaussian noise,it was of great significance to integrated navigation systems described by the non-Gaussian noise.The proposed algorithm was tested in a vehicle's maneuvering trajectory,which included six flight phases: climbing,level flight,left turning,level flight,right turning and level flight.Simulation results are presented to demonstrate the improved performance of the FUPF over conventional federated unscented Kalman filter(FUKF).For instance,the mean of position-error decreases from(0.640×10 6 rad,0.667×10 6 rad,4.25 m)of FUKF to(0.403×10-6 rad,0.251 × 10 6 rad,1.36 m)of FUPF.In comparison of the FUKF,the FUPF performs more accurate in the SINS/CNS/GPS system described by the nonlinear/non-Gaussian error models.

    In response to an inquiry by the Department of Mineral Resources in Thailand, the Energy & Environmental Research Center (EERC) prepared a program to assess the responsiveness of Sin Pun lignite to the temperature and pressure conditions of hot-water drying. The results indicate that drying made several improvements in the coal, notably increases in heating value and carbon content and reductions in equilibrium moisture and oxygen content. The equilibrium moisture content decreased from 27 wt% for the raw coal to about 15 wt% for the hot-water-dried (HWD) coals. The energy density for a pumpable coal-water fuel (CWF) indicates an increase from 4500 to 6100 Btu/lb by hot-water drying. Approximately 650 lb of HWD Sin Pun CWF were fired in the EERC`s combustion test facility. The fuel burned extremely well, with no feed problems noted during the course of the test. Fouling and slagging deposits each indicated a very low rate of ash deposition, with only a dusty layer formed on the cooled metal surfaces. The combustor was operated at between 20% and 25% excess air, resulting in a flue gas SO{sub 2} concentration averaging approximately 6500 parts per million.

  10. Sin práctica no hay discurso, sin cuerpo no hay saber: Sobre legitimidades en las teorías de la descolonización

    Maria Ximena Postigo

    2016-03-01

    En todo proceso de descolonización del saber, tan importante como la afirmación de una autonomía epistemológica y práctica es el reconocimiento del lugar de enunciación desde el que esta se produce. Una teoría de la descolonización elaborada desde la observación de los movimientos sociales no es semejante a una producida desde el propio movimiento social. En el primer caso, la teoría de lo de-colonial no deriva ni nace de una práctica. Walter Mignolo, por ejemplo, quien define su propuesta teórica como “la intervención de un pensador de-colonial”, escribe desde este lugar. En el segundo caso, la teoría se piensa desde y para el movimiento de los cuerpos. Así, Silvia Rivera Cusicanqui –para quien postulados como los de Mignolo dan cuenta de otra forma de colonialismo­– sostiene que un pensamiento de la descolonización es inimaginable sin una práctica descoloniozadora. En este contexto interno-externo, una mirada al Estado Plurinacional desde intervenciones como las de Mignolo tiende a una idealización binaria que no contribuye al proceso descolonizador sino, más bien, a una rearticulación del pensamiento occidental. A su vez, esta idealización es desmentida por discursos internos que ven en el gobierno de Evo Morales una incoherencia entre el discurso y la práctica. Este artículo explora todas estas instancias, reconociendo en las teorías producidas desde la lucha los pilares del Estado Plurinacional, y en las tensiones entre poderosos aquello que más bien, oscurece el valor del movimiento social.

    Full Text Available An improved method of gyrocompass alignment for strap-down inertial navigation system (SINS on moving base assisted with Doppler velocity log (DVL is proposed in this paper. After analyzing the classical gyrocompass alignment principle on static base, implementation of compass alignment on moving base is given in detail. Furthermore, based on analysis of velocity error, latitude error, and acceleration error on moving base, two improvements are introduced to ensure alignment accuracy and speed: (1 the system parameters are redesigned to decrease the acceleration interference and (2 a data repeated calculation algorithm is used in order to shorten the prolonged alignment time caused by changes in parameters. Simulation and test results indicate that the improved method can realize the alignment on moving base quickly and effectively.

    Any plasma diagnostic in ITER must be able to operate at temperatures in excess of 200 °C and neutron loads corresponding to 0.1 dpa over its lifetime. To achieve this aim for the bolometer diagnostic, a miniaturized metal resistor bolometer detector based on Pt absorbers galvanically deposited on SiN membranes is being developed. The first two generations of detectors featured up to 4.5 μm thick absorbers. Results from laboratory tests are presented characterizing the dependence of their calibration constants under thermal loads up to 450 °C. Several detectors have been tested in ASDEX Upgrade providing reliable data but also pointing out the need for further optimization. A laser trimming procedure has been implemented to reduce the mismatch in meander resistances below 1% for one detector and the thermal drifts from this mismatch.

    2014-01-01

    Transfer alignment is an effective alignment method for the strapdown inertial navigation system (SINS) of airborne weapon systems. The traditional transfer alignment methods for large misalignment angles alignment use nonlinear transfer align-ment models and incorporate nonlinear filtering. A rapid transfer alignment method with linear models and linear filtering for ar-bitrary misalignment angles is presented. Through the attitude quaternion decomposition, the purpose of transfer alignment is converted to estimate a constant quaternion. Employing special manipulations on measurement equation, velocity and attitude linear measurement equations are derived. Then the linear trans-fer alignment model for arbitrary misalignment angles is built. An adaptive Kalman filter is developed to handle modeling errors of the measurement noise statistics. Simulation results show feasibili-ty and effectiveness of the proposed method, which provides an alternative rapid transfer alignment method for airborne weapons.

  6. The volunteer and the sannyăsin: archetypes of retirement in America and India.

    Savishinsky, Joel

    2004-01-01

    Cultures differ in their models of the life course, including the number and the content of the stages through which people are expected to pass. Among those societies that recognize a period of retirement, the developmental tasks and opportunities that older individuals face are shaped by cultural ideas about morality, spirituality, passion, and fulfillment. This article examines two archetypes for retirement: the American volunteer, and the Indian sannyăsin or "renouncer." Drawing on ethnographic data from a study of American retirees and descriptions of spiritual seekers in India, it considers the social roles these ideal types play, their self and their public images, the congruence between cultural expectations and their actual experiences, and the underlying values these people embody. It suggests that while older American volunteers view retirement as an entitlement, they also stress their obligation to use free time to pay back their society for the benefits they have enjoyed. They thus add a moral dimension to a period often stereotypically characterized by a "busy ethic" and a mindframe of self-indulgence. India's sannyăsins, however, enter a life-stage of social withdrawal and spiritual pursuit after years of fulfilling their adult commitments to family and community. Yet, in their self-denial and renunciation of worldly engagements, they model for others the religious rewards that can follow after leading a dutiful life. These archetypes of aging thus bring out their cultures' contrasting emphases on inner- versus outer-directedness, self-development versus self-effacement, and personal freedom versus social responsibility.

    Full Text Available To confirm or refute the widely held idea that the sealing operation is vital to guarantee the good resistance of anodised aluminium to atmospheric corrosion, unsealed anodised specimens with three different film thicknesses were exposed in 9 atmospheres in Iberoamérica with salinity values of between 3.9 and 684 mg m sup>-2 day-1 of chlorides. Using a wide variety of techniques, from scanning and transmission electron microscopy to direct measurements by gravimetry, and including indirect measurements by electrochemical techniques as well as standard sealing quality control tests, the self-sealing capacity of unsealed anodic coatings during atmospheric exposure is demonstrated. Surprisingly, unlike other types of protective coatings, the quality of anodic films improves with ageing. Keywords

    Para confirmar o rebatir la idea, muy difundida, de que la operación de sellado es imprescindible para garantizar una buena resistencia del aluminio anodizado a la corrosión atmosférica, se expusieron muestras de anodizados sin sellar, de tres espesores diferentes, en 9 atmósferas de Iberoamérica, con salinidades comprendidas entre 3,9 y 684 mg m-2 d-1 de cloruros. Por las más variadas técnicas, desde la microscopía electrónica de barrido o transmisión a la medida directa por gravimetría, pasando por los ensayos normalizados de control de calidad del sellado y la medida indirecta por técnicas electroquímicas, se demuestra la capacidad de autosellado, durante la exposición a la atmósfera, de los recubrimientos anódicos sin sellar. Sorprendentemente, a diferencia de lo que ocurre en recubrimientos protectores de otra naturaleza, la calidad de los anodizados mejora con el envejecimiento.

General morbidity was assessed using Clavien–Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. Diagnosis and Outcomes: The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450–540 minutes), the mean estimated blood loss was 266 mL (range 100–400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8–24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Lessons: Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy. PMID:28099344

  9. Estonian total ozone climatology

    Directory of Open Access Journals (Sweden)

    Full Text Available The climatological characteristics of total ozone over Estonia based on the Total Ozone Mapping Spectrometer (TOMS data are discussed. The mean annual cycle during 1979–2000 for the site at 58.3° N and 26.5° E is compiled. The available ground-level data interpolated before TOMS, have been used for trend detection. During the last two decades, the quasi-biennial oscillation (QBO corrected systematic decrease of total ozone from February–April was 3 ± 2.6% per decade. Before 1980, a spring decrease was not detectable. No decreasing trend was found in either the late autumn ozone minimum or in the summer total ozone. The QBO related signal in the spring total ozone has an amplitude of ± 20 DU and phase lag of 20 months. Between 1987–1992, the lagged covariance between the Singapore wind and the studied total ozone was weak. The spring (April–May and summer (June–August total ozone have the best correlation (coefficient 0.7 in the yearly cycle. The correlation between the May and August total ozone is higher than the one between the other summer months. Seasonal power spectra of the total ozone variance show preferred periods with an over 95% significance level. Since 1986, during the winter/spring, the contribution period of 32 days prevails instead of the earlier dominating 26 days. The spectral densities of the periods from 4 days to 2 weeks exhibit high interannual variability.

    Full Text Available Owing to their numerous merits, such as compact, autonomous and independence, the strapdown inertial navigation system (SINS and celestial navigation system (CNS can be used in marine applications. What is more, due to the complementary navigation information obtained from two different kinds of sensors, the accuracy of the SINS/CNS integrated navigation system can be enhanced availably. Thus, the SINS/CNS system is widely used in the marine navigation field. However, the CNS is easily interfered with by the surroundings, which will lead to the output being discontinuous. Thus, the uncertainty problem caused by the lost measurement will reduce the system accuracy. In this paper, a robust H∞ filter based on the Krein space theory is proposed. The Krein space theory is introduced firstly, and then, the linear state and observation models of the SINS/CNS integrated navigation system are established reasonably. By taking the uncertainty problem into account, in this paper, a new robust H∞ filter is proposed to improve the robustness of the integrated system. At last, this new robust filter based on the Krein space theory is estimated by numerical simulations and actual experiments. Additionally, the simulation and experiment results and analysis show that the attitude errors can be reduced by utilizing the proposed robust filter effectively when the measurements are missing discontinuous. Compared to the traditional Kalman filter (KF method, the accuracy of the SINS/CNS integrated system is improved, verifying the robustness and the availability of the proposed robust H∞ filter.

    Full Text Available The integration of the Strapdown Inertial Navigation System and Global Navigation Satellite System (SINS/GNSS has been implemented for land-based gravimetry and has been proven to perform well in estimating gravity. Based on the mGal-level gravimetry results, this research aims to construct and develop a land-based SINS/GNSS gravimetry device containing a navigation-grade Inertial Measurement Unit. This research also presents a feasibility analysis for groundwater resource detection. A preliminary comparison of the kinematic velocities and accelerations using multi-combination of GNSS data including Global Positioning System, Global Navigation Satellite System, and BeiDou Navigation Satellite System, indicates that three-system observations performed better than two-system data in the computation. A comparison of gravity derived from SINS/GNSS and measured using a relative gravimeter also shows that both agree reasonably well with a mean difference of 2.30 mGal. The mean difference between repeat measurements of gravity disturbance using SINS/GNSS is 2.46 mGal with a standard deviation of 1.32 mGal. The gravity variation because of the groundwater at Pingtung Plain, Taiwan could reach 2.72 mGal. Hence, the developed land-based SINS/GNSS gravimetry can sufficiently and effectively detect groundwater resources.

    SIN3 gene product operates as a repressor for a huge amount of genes in Saccharomyces cerevisiae. Sin3 protein with a mass of about 175 kDa is a member of the RPD3 protein complex with an assessed mass of greater than 2 million Da. It was previously shownthat RPD3 gene mutations influence recombination and repair processes in S. cerevisiae yeasts. We studied the impacts of the sin3 mutation on UV-light sensitivity and UV-induced mutagenesis in budding yeast cells. The deletion ofthe SIN3 gene causes weak UV-sensitivity of mutant budding cells as compared to the wild-type strain. These results show that the sin3 mutation decreases both spontaneous and UV-induced levels of levels. This fact is hypothetically related to themalfunction of ribonucleotide reductase activity regulation, which leads to a decrease in the dNTP pool and the inaccurate error-prone damage bypass postreplication repair pathway, which in turn provokes a reduction in the incidence of mutations.

    Total lymphoid irradiation by itself can produce sufficient immunosuppression to prolong the survival of a variety of organ allografts in experimental animals. The degree of prolongation is dose-dependent and is limited by the toxicity that occurs with higher doses. Total lymphoid irradiation is more effective before transplantation than after, but when used after transplantation can be combined with pharmacologic immunosuppression to achieve a positive effect. In some animal models, total lymphoid irradiation induces an environment in which fully allogeneic bone marrow will engraft and induce permanent chimerism in the recipients who are then tolerant to organ allografts from the donor strain. If total lymphoid irradiation is ever to have clinical applicability on a large scale, it would seem that it would have to be under circumstances in which tolerance can be induced. However, in some animal models graft-versus-host disease occurs following bone marrow transplantation, and methods to obviate its occurrence probably will be needed if this approach is to be applied clinically. In recent years, patient and graft survival rates in renal allograft recipients treated with conventional immunosuppression have improved considerably, and thus the impetus to utilize total lymphoid irradiation for its immunosuppressive effect alone is less compelling. The future of total lymphoid irradiation probably lies in devising protocols in which maintenance immunosuppression can be eliminated, or nearly eliminated, altogether. Such protocols are effective in rodents. Whether they can be applied to clinical transplantation remains to be seen.

    Full Text Available Introducción La utilización de drenaje en la artroplastia total de rodilla es una práctica ampliamente aceptada en la comunidad ortopédica; sin embargo, en la bibliografía, no se encuentra evidencia concluyente sobre su beneficio. El propósito de este estudio fue comparar dos grupos de pacientes sometidos a artroplastia total de rodilla         primaria con drenaje y sin él. Materiales y Métodos Se llevó a cabo un estudio prospectivo aleatorizado en el que se realizaron 76 artroplastias totales de rodilla primarias; se dividió a los pacientes en dos grupos: grupo A, con drenaje y grupo B, sin drenaje. Se evaluaron el número de unidades de sangre transfundidas, el débito de sangre en los pacientes con drenaje, las complicaciones posoperatorias y el tiempo de hospitalización. Antes de la cirugía y después de ella, se registró el diámetro del muslo, el rango de movilidad, el hematocrito y la hemoglobina en ambos grupos. Resultados No se hallaron diferencias estadísticamente significativas en el diámetro del muslo, el rango de movilidad, el hematocrito, la hemoglobina, el número de transfusiones y la estadía hospitalaria. El número de complicaciones en el grupo B (sin drenaje fue mayor (p = 0,019: dos infecciones profundas, dos casos de celulitis, uno de flictena, una fractura de cadera, una trombosis venosa superficial, una trombosis venosa profunda y un tromboembolismo pulmonar. Conclusión Los pacientes sin drenaje posoperatorio sufrieron más complicaciones.

    This paper reports an updated measurement of the standard model CP violation parameter sin 2β using the CDF Detector at Fermilab. The entire run I data sample of 110 pb-1 of proton-antiproton collisions at s=1.8 TeV is used to identify a signal sample of ~400 B-->J/ψ K0S events, where J/ψ-->μ+μ- and K0S-->π+π-. The flavor of the neutral B meson is identified at the time of production by combining information from three tagging algorithms: a same-side tag, a jet-charge tag, and a soft-lepton tag. A maximum likelihood fitting method is used to determine sin 2β=0.79+0.41-0.44(stat+syst). This value of sin 2β is consistent with the standard model prediction, based upon existing measurements, of a large positive CP-violating asymmetry in this decay mode.

  4. Algebraic totality, towards completeness

    Tasson, Christine

    2009-01-01

    Finiteness spaces constitute a categorical model of Linear Logic (LL) whose objects can be seen as linearly topologised spaces, (a class of topological vector spaces introduced by Lefschetz in 1942) and morphisms as continuous linear maps. First, we recall definitions of finiteness spaces and describe their basic properties deduced from the general theory of linearly topologised spaces. Then we give an interpretation of LL based on linear algebra. Second, thanks to separation properties, we can introduce an algebraic notion of totality candidate in the framework of linearly topologised spaces: a totality candidate is a closed affine subspace which does not contain 0. We show that finiteness spaces with totality candidates constitute a model of classical LL. Finally, we give a barycentric simply typed lambda-calculus, with booleans ${\\mathcal{B}}$ and a conditional operator, which can be interpreted in this model. We prove completeness at type ${\\mathcal{B}}^n\\to{\\mathcal{B}}$ for every n by an algebraic metho...

  5. Total Energy Monitor

    Energy Technology Data Exchange (ETDEWEB)

    Friedrich, S

    2008-08-11

    The total energy monitor (TE) is a thermal sensor that determines the total energy of each FEL pulse based on the temperature rise induced in a silicon wafer upon absorption of the FEL. The TE provides a destructive measurement of the FEL pulse energy in real-time on a pulse-by-pulse basis. As a thermal detector, the TE is expected to suffer least from ultra-fast non-linear effects and to be easy to calibrate. It will therefore primarily be used to cross-calibrate other detectors such as the Gas Detector or the Direct Imager during LCLS commissioning. This document describes the design of the TE and summarizes the considerations and calculations that have led to it. This document summarizes the physics behind the operation of the Total Energy Monitor at LCLS and derives associated engineering specifications.

    After a code-table has been established by means of node association information from signal flow graph, the totally coded method (TCM) is applied merely in the domain of code operation beyond any figure-earching algorithm. The code-series (CS) have the holoinformation nature, so that both the content and the sign of each gain- term can be determined via the coded method. The principle of this method is simple and it is suited for computer programming. The capability of the computer-aided analysis for switched current network(SIN) can be enhanced.

    Full Text Available Resumen:Tomando como base la lectura del cuento “Juan Sin Miedo” realizada por tres sujetos adolescentes, pretendo responder a la pregunta sobre los principales temores que enfrenta la población costarricense adolescente en la actualidad. Las respuestas giran en torno a tres núcleos significativos: el miedo a la exclusión económica y social, materializada en el trato discriminatorio hacia quienes no se adecuan a los criterios impuestos por la sociedad de consumo; el miedo a la escuela, en tanto excluye a quienes no se ajustan a la norma esperada de desempeño académico; y el miedo al otro, en particular a la calle y la escuela como espacios de violencia. Concluyo señalando que, detrás de dichos temores, es posible leer un anhelo de pertenencia; de aprecio sincero y gratuito, en que no medie el rendimiento académico de la persona; así como un anhelo de seguridad en el entorno cercano.Abstract:Based on a reading of the short story Juan Sin Miedo («fearless John» by three adolescents, I intend to provide an answer to the question of the main fears that the Costa Rican adolescent population faces at present. The answers given by these adolescents focus on three significant central elements: fear of economic and social exclusion, expressed through discriminatory treatment towards those who do not subject themselves to the criteria imposed by the consumer society; fear of school in that it excludes those who do not meet the expected academic performance standard; and fear of others, particularly out in the street and in school as realms of violence. I conclude by pointing out that it is possible to visualise, behind such fears, a desire to belong; a longing for both, a sincere and free appreciation where the individual‟s academic performance is not what counts, and for safety within the immediate surroundings.

    GPS/SINS组合导航系统虽然能很好地解决惯导系统的误差累积问题,但当GPS信号失效时,GPS/SINS组合导航系统不能正常工作或导航能力急剧降低.为提高车载松组合导航系统的精度和完整性,提出在GPS失效时采用OD(里程计)辅助SINS实现导航,推导出所需的GPS/SINS组合导航滤波方程和OD/SINS组合导航滤波方程,并进行地面车载试验.实验结果显示在GPS短时失效时,OD/SINS组合导航具有较高导航精度.%The error accumulation of inertial navigation system is solved well by GPS/SINS integrated navigation system, but when GPS signal failure, GPS/SINS integrated navigation system does not work normally or works in low precision. In order to improve positioning precision and integrity, odometer speed information is u-tilized to assist SINS when GPS signal failure. The Kalman filtering dynamic model for the proposed car GPS/ DR integrated navigation system is deduced. Car experiment is performed to verify the proposed method. The results show that OD/SINS has higher navigation accuracy, when GPS signal failure for short time.

    Full Text Available Total hip arthroplasty is most common reconstructive hip procedure in adults. In this surgery we replace some parts of the upper femur and acetabulum with biocompatible materials. The main goal of this surgery is to eliminate pain and regain full extent of joint motion, maintaining hip stability. Surgical technique, biomaterials, design of the prosthesis and fixation techniques have evolved with time adjusting to each other. After total hip arthroplasty patients’ quality of life should be improved. There are many various postoperative complications. Some of them are fatal, and some are minor, which may become manifested years after surgery. Each next surgical procedure following previous hip surgery is associated with considerably lower chances to be successful. Therefore, in primary total hip arthroplasty, preoperative evaluation and preparation of patients are essential. Every orthopaedic surgeon needs to improve already adopted surgical skills applying them with precision and without compromise, with the main goal to achieve long-term durability of the selected implant. The number of total hip arthroplasties will also increase in future, and newer and higher quality materials will be used.

  6. Optimization Algorithm for Kalman Filter Exploiting the Numerical Characteristics of SINS/GPS Integrated Navigation Systems.

    2015-11-11

    Aiming at addressing the problem of high computational cost of the traditional Kalman filter in SINS/GPS, a practical optimization algorithm with offline-derivation and parallel processing methods based on the numerical characteristics of the system is presented in this paper. The algorithm exploits the sparseness and/or symmetry of matrices to simplify the computational procedure. Thus plenty of invalid operations can be avoided by offline derivation using a block matrix technique. For enhanced efficiency, a new parallel computational mechanism is established by subdividing and restructuring calculation processes after analyzing the extracted "useful" data. As a result, the algorithm saves about 90% of the CPU processing time and 66% of the memory usage needed in a classical Kalman filter. Meanwhile, the method as a numerical approach needs no precise-loss transformation/approximation of system modules and the accuracy suffers little in comparison with the filter before computational optimization. Furthermore, since no complicated matrix theories are needed, the algorithm can be easily transplanted into other modified filters as a secondary optimization method to achieve further efficiency.

    Based on SINFONI Ha, [NII] and [SII] AO data of 30 z \\sim 2 star-forming galaxies (SFGs) from the SINS and zcSINF surveys, we find a strong correlation of the Ha broad flux fraction with the star formation surface density of the galaxy, with an apparent threshold for strong outflows occurring at 1 Msun yr^-1 kpc^-2. Above this threshold, we find that SFGs with logm_\\ast>10 have similar or perhaps greater wind mass loading factors (eta = Mdotout/SFR) and faster outflow velocities than lower mass SFGs. This trend suggests that the majority of outflowing gas at z \\sim 2 may derive from high-mass SFGs, and that the z \\sim 2 mass-metallicity relation is driven more by dilution of enriched gas in the galaxy gas reservoir than by the efficiency of outflows. The mass loading factor is also correlated with the SFR and inclination, such that more star-forming and face-on galaxies launch more powerful outflows. For galaxies that have evidence for strong outflows, we find that the broad emission is spatially extended to ...

    The field radiometric and laboratory measurements were performed at the Sin Quyen copper deposit in North Vietnam. The field gamma-ray spectrometry indicated the concentration of uranium ranging from 5.5 to 87 ppm, thorium from 5.6 to 33.2 ppm, and potassium from 0.3 to 4.7%. The measured dose rates ranged from 115 to 582 nGy/h, the highest doses being at the copper ore. Concentrations in the solid samples were in the range of 20-1700 Bq/kg for uranium, 20-92.7 Bq/kg for thorium, and 7-1345 Bq/kg for potassium. The calculated doses were from 22 to 896 nGy/h; both measured and calculated dose rates are mostly related to uranium. Concentrations of radium in water samples were below 0. 17 Bq/L. Uranium in water samples was significantly higher than the hydrogeological background; the maximum of 13 Bq/L was at the waste zone pool, but neither radium nor uranium were present in tap water. Radon concentration in the dwelling air was from 42 to 278 Bq/m3 for 222Rn and from 8 to 193 Bq/m3 for 220Rn.

    We have studied the structural, morphological and optical properties of In2S3 layers deposited on glass substrate by the spray pyrolysis method with the molar ratio S/In varies from 1 to 4. The substrate temperature was maintained at 613 K. The characteristics of these films have been determined by X-ray diffraction (XRD), optical absorption-transmission and atomic force microscopy (AFM). Their structure is strongly dependent on the molar ratio. The deposit is mainly constituted by the β phase towards (4 0 0) direction. No characteristic peaks were observed for other impurities such as In2O3, S or In2(OH)3. The best crystallinity and surface morphology are obtained at molar ratio equal to 2.5. At this ratio, the crystallites coalesce and the local roughness is of the order of 1 nm. Optical transmission of 80% has been achieved in the visible spectrum. In2S3 band gap energy reached 2.63 eV from layers with x = 2 and deposited at Ts = 613 K.

In order to improve the reliability of the airborne SINS/CNS integrated navigation system, meet the demand of the long-endurance and high precision navigation, use the tight combination way, single star patrol algorithm to get the position and attitude. There exists filtering divergence problem because of the model error and the system measurement noise is uncertain, put forward a new fuzzy adaptive kalman filtering algorithm. Adjust the size of measurement noise to prevent the filter divergence; the positioning accuracy of integrated navigation system can be improved through BeiDou satellite. Without the information of BeiDou satellite, based on the level of the virtual reference, the navigation precision of integrated navigation system can be ensured over a period of time.

    2014-03-01

    Full Text Available In the spirit of critical reflection, we examine how the field of global health might surmount current challenges and prioritize its ethical mandate, namely to achieve, for all people, equity in health. We use the parlance of mastering deadly sins and striving for greater virtues in an effort to review what is needed to transform global health action. Global health falls prey to four main temptations: coveting silo gains, lusting for technological solutions, leaving broad promises largely unfulfilled, and boasting of narrow successes. This necessitates a change of heart: to keep faith with the promise it made, global health requires a realignment of core values and a sharper focus on the primacy of relationships with the communities it serves. Based on the literature to date, we highlight six steps to re-orienting global health action. Articulating a coherent global health agenda will come from principled action, enacted through courage and prudence in decision-making to foster people-centered systems of care over the entire lifespan.

  17. SEXUAL SIN IN NEW TESTAMENT TIMES BIBLICAL AND CONTEXTUAL PERSPECTIVES IN NIGERIA

    2011-01-01

    Full Text Available Christian ethical standards are breaking down in our nation. Many believe now that individuals have rights, including the right to make their own sexual decisions and that sexual behaviour is an individual's private matter. How then can Christianity or the Church relate to the sexual and marriage problems today? If the bible really has a standard that can safe-guide sexual behaviours, why is sexual sin common even within the Church? Historical-contextual and sociological methods were employed in this paper in order to clearly state the New Testament understanding. The study contextualized Biblical teachings, particularly on sex and marriage to the Africans. Findings revealed that the Bible places sex and sexual activity within the larger context of holiness and faithfulness. In this regard, the Bible presents an honest and often detailed explanation of God's design for sex and its place in human life. The New Testament presents sexual deviance as an intentional rejection of God's authority as Creator and Lord. Invariably, Nigeria is characterized by loose sexual morality, which cannot be divorced from incessant poverty, unemployment and illiteracy, as well as the flood of immigrants to Africa and to Nigeria who brought new forms of family life and new sexual customs. The paper concludes that there is clear evidence that our memories are failing on Jesus’ injunctions in this regard, hence, there is need to draw upon the Christian faith for guidance but African context should not be forgotten

  18. El dilema de los recursos naturales comunes "sin doliente(s"

    Full Text Available Desde la antigüedad, personas como Aristóteles y Tucídides plantearon una teoría básica que evidenció el comportamiento que las personas tienen con respecto al uso continuo de algún recurso natural común. Dejaron entrever el conflicto, normalmente económico, que se genera por la intervención de intereses individuales sobre los bienes públicos. La tragedia de los comunes (término popularizado por Garrett Hardin en 1968 explica cómo el acceso sin restricciones a un recurso "comunal" finito conduce a la sobreexplotación y al agotamiento de dicho recurso por el aumento desmedido en su demanda. Esto ocurre porque el grupo o los individuos que aprovechan los recursos no cargan directamente con los costos de su explotación. Entonces frente a la premisa de que el recurso es de todos y para todos, pero en última instancia, no pertenece a nadie, cabe preguntarse qué prima: ¿Un interés individual sobre un colectivo? O tal vez, ¿es una cuestión de enfoque etológico?

    Photoelectron imaging experiments were conducted on small silicon cluster anions, Sin- (n =2-7), acquired at a photon energy of 3.49 eV (355 nm). Electronic transitions arising from the anion ground states are observed, and the evaluated vertical detachment energies agree well with previous measurements and theoretical calculations. The anisotropy β parameters have also been determined for each unique feature appearing in the photoelectron angular distributions at the employed photon energy. Separate calculations using density functional theory are also undertaken to determine the relative atomic orbital contributions constructing the interrogated highest occupied and low-lying molecular orbitals of a specific cluster. A method to interpret the observed cluster angular distributions, term the β-wave approach, is then implemented which provides quantitative predictions of the anisotropy β parameter for partial wave emission from molecular orbitals partitioned by varying contributions of atomic orbital angular momenta. Highlighted in the β-wave analysis is the ability of discriminating between disparate molecular orbitals from two nearly isoenergetic structural isomers of opposing point group symmetry for the Si4- and Si6- cluster ions, respectively.

  20. Elevated Cytokines, Thrombin and PAI-1 in Severe HCPS Patients Due to Sin Nombre Virus

    Full Text Available Sin Nombre Hantavirus (SNV, Bunyaviridae Hantavirus is a Category A pathogen that causes Hantavirus Cardiopulmonary Syndrome (HCPS with case fatality ratios generally ranging from 30% to 50%. HCPS is characterized by vascular leakage due to dysregulation of the endothelial barrier function. The loss of vascular integrity results in non-cardiogenic pulmonary edema, shock, multi-organ failure and death. Using Electric Cell-substrate Impedance Sensing (ECIS measurements, we found that plasma samples drawn from University of New Mexico Hospital patients with serologically-confirmed HCPS, induce loss of cell-cell adhesion in confluent epithelial and endothelial cell monolayers grown in ECIS cultureware. We show that the loss of cell-cell adhesion is sensitive to both thrombin and plasmin inhibitors in mild cases, and to thrombin only inhibition in severe cases, suggesting an increasing prothrombotic state with disease severity. A proteomic profile (2D gel electrophoresis and mass spectrometry of HCPS plasma samples in our cohort revealed robust antifibrinolytic activity among terminal case patients. The prothrombotic activity is highlighted by acute ≥30 to >100 fold increases in active plasminogen activator inhibitor (PAI-1 which, preceded death of the subjects within 48 h. Taken together, this suggests that PAI-1 might be a response to the severe pathology as it is expected to reduce plasmin activity and possibly thrombin activity in the terminal patients.

  1. Smokers' strategic responses to sin taxes: evidence from panel data in Thailand.

    White, Justin S; Ross, Hana

    2015-02-01

    In addition to quitting and cutting consumption, smokers faced with higher cigarette prices may compensate in several ways that mute the health impact of cigarette taxes. This study examines three price avoidance strategies among adult male smokers in Thailand: trading down to a lower-priced brand, buying individual sticks of cigarettes instead of packs, and substituting roll-your-own tobacco for factory-manufactured cigarettes. Using two panels of microlevel data from the International Tobacco Control Southeast Asia Study, collected in 2005 and 2006, we estimate the effects of a substantial excise tax increase implemented throughout Thailand in December 2005. We present estimates of the marginal effects and price elasticities for each of five consumer behaviors. We find that, controlling for baseline smoking characteristics, sociodemographics, and policy variables, quitting is highly sensitive to changes in cigarette prices, but so are brand choice, stick-buying, and use of roll-your-own tobacco. Neglecting such strategic responses leads to overestimates of a sin tax's health impact, and neglecting product substitution distorts estimates of the price elasticity of cigarette demand. We discuss the implications for consumer welfare and several policies that mitigate the adverse impact of consumer responses.

    The reliable determination of rotation-activity correlations (RACs) depends on precise measurements of the following stellar parameters: T eff, parallax, radius, metallicity, and rotational speed v sin i. In this paper, our goal is to focus on the determination of these parameters for a sample of K and M dwarfs. In a future paper (Paper II), we will combine our rotational data with activity data in order to construct RACs. Here, we report on a determination of effective temperatures based on the (R-I) C color from the calibrations of Mann et al. and Kenyon & Hartmann for four samples of late-K, dM2, dM3, and dM4 stars. We also determine stellar parameters (T eff, log(g), and [M/H]) using the principal component analysis-based inversion technique for a sample of 105 late-K dwarfs. We compile all effective temperatures from the literature for this sample. We determine empirical radius-[M/H] correlations in our stellar samples. This allows us to propose new effective temperatures, stellar radii, and metallicities for a large sample of 612 late-K and M dwarfs. Our mean radii agree well with those of Boyajian et al. We analyze HARPS and SOPHIE spectra of 105 late-K dwarfs, and we have detected v sin i in 92 stars. In combination with our previous v sin i measurements in M and K dwarfs, we now derive P/sin i measures for a sample of 418 K and M dwarfs. We investigate the distributions of P/sin i, and we show that they are different from one spectral subtype to another at a 99.9% confidence level.

    The first enantioselective synthesis of (-)-conolutinine was achieved in 10 steps. The synthesis featured a catalytic asymmetric bromocyclization of tryptamine to forge the tricycle intermediate. Hydration of an alkene catalyzed by Co(acac)2 was also employed as a key step to diastereoselectively introduce the tertiary alcohol moiety. The absolute configuration of (-)-conolutinine was established to be (2S,5aS,8aS,13aR) based on this asymmetric total synthesis.

    Full Text Available La conjunción de una serie de factores económicos, sociales y políticos en la Argentina de los noventa dio como resultado el momento de mayor fragmentación política de los trabajadores. Esto fue logrado a partir de la desestructuración de la sociedad comenzada en la dictadura militar de mediados de los setenta y profundizada mediante la implantación del modelo neoliberal a comienzos de la última década del siglo XX. Se terminó entonces dilapidando toda posibilidad de consolidación de la una clase obrera mas o menos homogénea, cuyo germen había sido prefigurado bajo el primer gobierno peronista y se había puesto de manifiesto en las distintas etapas de la resistencia a gobiernos que amenazaban los intereses de los sectores populares. Sin dudas se trataba de políticas destinadas a asegurar una sociedad disciplinada con el fin de consolidar el poder de los sectores dominantes más relacionados con la especulación financiera y los intereses de los grupos económicos transnacionales. Al mismo tiempo, no sólo se lograba una sociedad económica y socialmente fragmentada sino que se reproducía una cultura individualista extrema que potenciaba dicha situación. En el presente artículo estudiamos los elementos condicionantes en la cultura del trabajo que existían en la historia previa a la implantación del modelo neoliberal y los factores contextuales que permitieron su desarrollo. Al mismo tiempo analizamos los factores que, en un marco de fragmentación y transformación constante, estructuran actualmente las identidades del trabajo.

En la inactivación microbiana por CEPA!, el blanco principal es la membrana celular que, al ser sometida a campos eléctricos de alta intensidad, se hace permeable formando huecos o poros cuyo tamaño se incrementa a medida que aumenta la intensidad del campo eléctrico o el tiempo de tratamiento o se reduce la resistencia iónica del medio de pulsación. Por otra parte, los PL inducen reacciones fotoquímicas y fototérmicas en los alimentos, causando la muerte de gran cantidad de microorganismos, especialmente en productos alimenticios envasados. Los CMO producen simulación o inhibición en el crecimiento y reproducción de los microorganismos, un simple pulso de intensidad de 5-10 teslas y frecuencias de 5-500 kHz es suficiente para reducir el número de microorganismos en un mínimo de 2 ciclos logarítmicos. Se ha comprobado que estas tecnologías alargan la vida de anaquel de diversos productos alimenticios y pueden ser consideradas como sustitutos parciales de los procesos convencionales de pasteurización y esterilización de alimentos por tratamientos térmicos.

    2014-06-01

    Full Text Available Drawing on periodicals as the principal documental source, this article aims to demonstrate how the copious literary production and biography of Faustina Sáez de Melgar (1833? was closely linked to journalism. The creator of several magazines aimed at women, she seems to regard fashion magazines as a way of encouraging reading habits in the home. She asserts that education is the key to delivering women from their social marginalisation, which she denounced as a form of slavery. Although an active supporter of abolitionism -author of the drama La cadena rota- she did not consider women’s liberation to require any break in social norms, as it can be found within marriage, the maintaining of patriarchal structures and the practising of Christian virtues. Her thought sometimes appears opportunistic and contradictory. This is possibly a result of a cautious strategy, in which she sought to achieve only what was possible in her epoch.Con documentación hemerográfica como fuente principal, el artículo pretende poner de manifiesto la estrecha relación que con la prensa tuvo la extensa obra y la biografía de Faustina Sáez de Melgar (1833?. Creadora de varias revistas dirigidas a la mujer, vio en ellas un medio de fomentar la lectura en los hogares. Afirma que la educación es el medio por el que la mujer puede liberarse de la marginación social que padece y que ella denuncia como esclavitud. Autora del drama La cadena rota, comprometida con el abolicionismo, considera sin embargo innecesario romper ninguna: esa liberación llega además por el matrimonio y la práctica de las virtudes en una sociedad patriarcal cristiana. Sus opiniones parecen en ocasiones contradictorias y oportunistas. Posiblemente subyace una cautelosa estrategia en aplicación del “posibilismo”.

Triunfó Ortega con un amplio margen, en medio de acusaciones de fraude. En realidad, el FSLN pasó por encima de la Constitución y las normas que rigen el proceso electoral para alcanzar su contundente victoria. Una explicación de la victoria de Ortega, sin embargo, también debe considerar las enormes debilidades de la oposición que no logró articular un discurso y una visión social congruentes con las necesidades del país. Ortega, por el contrario, logró capturar la imaginación de millones de nicaragüenses que se debaten en la pobreza.The political life of Nicaragua in 2011 revolved around the November elections and, more specifically, around the future of the "Christian and socialist project of social solidarity" promoted and defended by the FSLN, led by Daniel Ortega. The FSLN won a landslide re-election amid accusations of electoral fraud. In fact, the FSLN manipulated the law, the institutions of the country and the electoral process to ensure its powerful victory. An explanation of the Sandinista victory, however, has to take into consideration the opposition parties inability to articulate a discourse and a vision of society congruent with the needs and aspirations of the Nicaraguan poor. The FSLN, on the other hand, was able to capture the imagination of this sector of Nicaraguan society.

    Andes virus (ANDV) and Sin Nombre virus (SNV) are rodent-borne hantaviruses that cause a highly lethal hemorrhagic fever in humans known as hantavirus pulmonary syndrome (HPS). There are no vaccines or specific drugs to prevent or treat HPS, and the pathogenesis is not understood. Syrian hamsters infected with ANDV, but not SNV, develop a highly lethal disease that closely resembles HPS in humans. Here, we performed a temporal pathogenesis study comparing ANDV and SNV infections in hamsters. SNV was nonpathogenic and viremia was not detected despite the fact that all animals were infected. ANDV was uniformly lethal with a mean time to death of 11 days. The first pathology detected was lymphocyte apoptosis starting on day 4. Animals were viremic and viral antigen was first observed in multiple organs by days 6 and 8, respectively. Levels of infectious virus in the blood increased 4 to 5 logs between days 6 and 8. Pulmonary edema was first detected ultrastructurally on day 6. Ultrastructural analysis of lung tissues revealed the presence of large inclusion bodies and substantial numbers of vacuoles within infected endothelial cells. Paraendothelial gaps were not observed, suggesting that fluid leakage was transcellular and directly attributable to infecting virus. Taken together, these data imply that HPS treatment strategies aimed at preventing virus replication and dissemination will have the greatest probability of success if administered before the viremic phase; however, because vascular leakage is associated with infected endothelial cells, a therapeutic strategy targeting viral replication might be effective even at later times (e.g., after disease onset).

    Ankle arthritis results in a stiff and painful ankle and can be a major cause of disability. For people with end-stage ankle arthritis, arthrodesis (ankle fusion) is effective at reducing pain in the shorter term, but results in a fixed joint, and over time the loss of mobility places stress on other joints in the foot that may lead to arthritis, pain and dysfunction. Another option is to perform a total ankle joint replacement, with the aim of giving the patient a mobile and pain-free ankle. In this article we review the efficacy of this procedure, including how it compares to ankle arthrodesis, and consider the indications and complications.

    The development and testing of a breadboard version of a highly sensitive total-organic-carbon (TOC) analyzer are reported. Attention is given to the system components including the CO2 sensor, oxidation reactor, acidification module, and the sample-inlet system. Research is reported for an experimental reagentless oxidation reactor, and good results are reported for linearity, sensitivity, and selectivity in the CO2 sensor. The TOC analyzer is developed with gravity-independent components and is designed for minimal additions of chemical reagents. The reagentless oxidation reactor is based on electrolysis and UV photolysis and is shown to be potentially useful. The stability of the breadboard instrument is shown to be good on a day-to-day basis, and the analyzer is capable of 5 sample analyses per day for a period of about 80 days. The instrument can provide accurate TOC and TIC measurements over a concentration range of 20 ppb to 50 ppm C.

Whereas Ursinus tended more towards an academic correctness in his Explicationum Catecheticarum, Olevianus added a pastoral and spiritual dimension in his Vester Grundt. Although some theologians questioned the role of Olevianus in the compilation of the Heidelberg Catechism, recent research adequately shows that both of them were indeed involved, and were well-endowed with the necessary background for providing a further exposition of the Catechism. Both of them emphasise the unquestionable and sole merit of Jesus Christ, through his vicarious death on the cross, as the only ground for God’s gracious forgiveness of the sinner. It is God’s free gift, appropriated through faith and trust in the merit of Christ. Hierdie artikel toon aan dat daar, wat die vergifnis van sonde betref, nie net groot ooreenstemming en dieselfde basiese benadering ten opsigte van geloofskwessies in die kommentare van Ursinus en Olevianus op die Heidelbergse Kategismus is nie, maar dat daar ook ’n waardevolle wedersydse aanvulling van mekaar se werk is. Albei het by geleentheid in Genéve onder Calvyn gestudeer: sy invloed is onmiskenbaar in hulle leerstellige benaderings. In Ursinus se Explicationum Catecheticarum weeg die akademiese korrektheid swaarder, terwyl daar in Olevianus se Vester Grundt ook ‘n pastorale en spirituele dimensie bykom. Olevianus se betrokkenheid by die opstel van die Heidelbergse Kategismus is soms sterk bevraagteken, maar nuwe navorsing laat genoegsaam blyk dat albei teoloë inderdaad deel gehad het daaraan, en ook goed toegerus was met

    Full Text Available Background: Primary total elbow arthroplasty (TEA is a challenging procedure for orthopedic surgeons. It is not performed as frequently as compared to hip or knee arthroplasty. The elbow is a nonweight-bearing joint; however, static loading can create forces up to three times the body weight and dynamic loading up to six times. For elderly patients with deformity and ankylosis of the elbow due to posttraumatic arthritis or rheumatoid arthritis or comminuted fracture distal humerus, arthroplasty is one of the option. The aim of this study is to analyze the role of primary total elbow arthroplasty in cases of crippling deformity of elbow. Materials and Methods: We analyzed 11 cases of TEA, between December 2002 and September 2012. There were 8 females and 3 males. The average age was 40 years (range 30-69 years. The indications for TEA were rheumatoid arthritis, comminuted fracture distal humerus with intraarticular extension, and posttraumatic bony ankylosis of elbow joint. The Baksi sloppy (semi constrained hinge elbow prosthesis was used. Clinico-radiological followup was done at 1 month, 3 months, 6 months, 1 year, and then yearly basis. Results: In the present study, average supination was 70° (range 60-80° and average pronation was 70° (range 60-80°. Average flexion was 135° (range 130-135°. However, in 5 cases, there was loss of 15 to 35° (average 25° of extension (45° out of 11 cases. The mean Mayo elbow performance score was 95.4 points (range 70-100. Arm length discrepancy was only in four patients which was 36% out of 11 cases. Clinico-radiologically all the elbows were stable except in one case and no immediate postoperative complication was noted. Radiolucency or loosening of ulnar stem was seen in 2 cases (18% out of 11 cases, in 1 case it was noted after 5 years and in another after 10 years. In second case, revision arthroplasty was done, in which only ulnar hinge section, hinge screw and lock screw with hexagonal head

    Indium sulfide (In2S3) thin films were prepared by chemical spray pyrolysis technique from solutions with different [S]/[In] ratios on glass substrates at a constant temperature of 250 °C. Thin films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), energy dispersive X-ray spectroscopy (EDS), Raman spectroscopy and optical transmittance spectroscopy. All samples exhibit a polycrystalline structure with a preferential orientation along (0, 0, 12). A good stoichiometry was attained for all samples. The morphology of thin film surfaces, as seen by SEM, was dense and no cracks or pinholes were observed. Raman spectroscopy analysis shows active modes belonging to β-ln2S3 phase. The optical transmittance in the visible range is higher than 60% and the band gap energy slightly increases with the sulfur to indium ratio, attaining a value of 2.63 eV for [S]/[In] = 4.5.

  9. Total disc replacement.

    2014-02-01

    Total disc replacement (TDR) (partial disc replacement will not be described) has been used in the lumbar spine since the 1980s, and more recently in the cervical spine. Although the biomechanical concepts are the same and both are inserted through an anterior approach, lumbar TDR is conventionally indicated for chronic low back pain, whereas cervical TDR is used for soft discal hernia resulting in cervicobrachial neuralgia. The insertion technique must be rigorous, with precise centering in the disc space, taking account of vascular anatomy, which is more complex in the lumbar region, particularly proximally to L5-S1. All of the numerous studies, including prospective randomized comparative trials, have demonstrated non-inferiority to fusion, or even short-term superiority regarding speed of improvement. The main implant-related complication is bridging heterotopic ossification with resulting loss of range of motion and increased rates of adjacent segment degeneration, although with an incidence lower than after arthrodesis. A sufficiently long follow-up, which has not yet been reached, will be necessary to establish definitively an advantage for TDR, particularly in the cervical spine.

    The total artificial heart (TAH) is a form of mechanical circulatory support in which the patient's native ventricles and valves are explanted and replaced by a pneumatically powered artificial heart. Currently, the TAH is approved for use in end-stage biventricular heart failure as a bridge to heart transplantation. However, with an increasing global burden of cardiovascular disease and congestive heart failure, the number of patients with end-stage heart failure awaiting heart transplantation now far exceeds the number of available hearts. As a result, the use of mechanical circulatory support, including the TAH and left ventricular assist device (LVAD), is growing exponentially. The LVAD is already widely used as destination therapy, and destination therapy for the TAH is under investigation. While most patients requiring mechanical circulatory support are effectively treated with LVADs, there is a subset of patients with concurrent right ventricular failure or major structural barriers to LVAD placement in whom TAH may be more appropriate. The history, indications, surgical implantation, post device management, outcomes, complications, and future direction of the TAH are discussed in this review.

    The Domizio-Flegreo Littoral and Agro Aversano area has been classified by the Italian Ministry of Environment (Italian Ministero dell'Ambiente e della Tutela del Territorio e del Mare) as a S.I.N. (Sito di Interesse Nazionale, L. 426/98 - Decreto 10 Gennaio 2000 - G.U. 29/5/01). In this category have been included all those contaminated lands that, both for their extension and their historical and present land use, are considered to be particularly harmful for human health. In Italy have been selected a total of 54 S.I.N.; among all of these, the Domizio-Flegreo Littoral and Agro Aversano S.I.N. is one of the widest (1564 Km2). The study area is located in north-western Campania region, from the Avella Mountain to the coastline, and from the Campi Flegrei area to the northern boundaries between Campania and Latium Regions. It includes a total of 77 towns from both Naples and Caserta provinces. The Domizio-Flegreo Littoral and Agro Aversano S.I.N. is characterized by a strongly urbanization in its internal portions, and by intensive agricultural activities in its northern and coastal portions. During past years this wide area has been the set of an unknown number of illegal activities controlled by the organized crime, including toxic waste disposal of unknown sources from different Regions of Italy, unauthorized building, intensive uncontrolled agricultural practices and so on. Part of these environmental crimes have been and are under investigations by Italian Authorities. For a geochemical characterization of this contaminated land, between May 2006 and January 2008, a total of 292 (179 in the Litorale Domizio-Flegreo and 113 in the Agro Aversano) top soils (5-15 cm depth) have been collected, with a sampling density of about 1 sample/5 Km2. The <100 mesh soil fraction has been analyzed with ICP-MS to determine the concentration of the 39 elements: Ag, Al, As, Au, B, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, Hg, K, La, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Se, Sn

  16. An updated measurement of sin 2beta with multiple flavor tags using a tag-combining algorithm

    Science.gov (United States)

    Gao, Tianjie

    This thesis reports an updated measurement of Standard Model CP violation parameter sin 2beta using the CDF detector at Fermilab. The signal samples of B0/B¯ 0 → J/psiKS and B0/B¯0 → psi(2 S)KS are extracted from the 110 pb -1 of p-p¯ collisions at s = 1.8 TeV. The flavor of the neutral B mesons is identified at the time of production by three tagging algorithms: a same-side tag, a soft-lepton tag, and an opposite-side-jet tag. The opposite-side-jet tag is a combination of the previously used jet-charge tag and a few new tags. A generic algorithm is developed to combine the tags to improve the tagging performance. A maximum likelihood fitting method is used to determine sin 2beta = 0.91+0.37-0.36 . The uncertainties are improved over the previous CDF measurement. The value is consistent with the standard model prediction of a large positive CP asymmetry in this decay mode. It is also consistent with the world average value of sin 2beta.

  17. A Method for SINS Alignment with Large Initial Misalignment Angles Based on Kalman Filter with Parameters Resetting

    2014-01-01

    Full Text Available In the initial alignment process of strapdown inertial navigation system (SINS, large initial misalignment angles always bring nonlinear problem, which causes alignment failure when the classical linear error model and standard Kalman filter are used. In this paper, the problem of large misalignment angles in SINS initial alignment is investigated, and the key reason for alignment failure is given as the state covariance from Kalman filter cannot represent the true one during the steady filtering process. According to the analysis, an alignment method for SINS based on multiresetting the state covariance matrix of Kalman filter is designed to deal with large initial misalignment angles, in which classical linear error model and standard Kalman filter are used, but the state covariance matrix should be multireset before the steady process until large misalignment angles are decreased to small ones. The performance of the proposed method is evaluated by simulation and car test, and the results indicate that the proposed method can fulfill initial alignment with large misalignment angles effectively and the alignment accuracy of the proposed method is as precise as that of alignment with small misalignment angles.

  18. Freedom in responsibility: on the relevance of "sin" as a hermeneutic guiding principle in bioethical decision making.

    Gräb-Schmidt, Elisabeth

    2005-08-01

    This essay deals with questions of responsibility concerning technology, in particular, gene technology and the special problem of research on embryos. I raise issues concerning the extent of humans' authority to act and the limits of human freedom. In what way is that freedom given, and what kind of responsibility results from it? By discussing various concepts of human freedom in the tradition of European philosophy, as juxtaposed to the Protestant understanding of freedom, this essay discusses the restricting limits, and the obligation to take responsibility. It will turn out that the question concerning freedom cannot be answered without understanding what being human involves. From a Christian perspective, this implies that the foundational relationship between human freedom and sin will be central to an assessment of the human ability to take responsibility. By obliterating the limits of human freedom, sin jeopardizes the very essence of that freedom. The project of taking into account the sinful state of the human condition thus aims at developing a realistic picture of the authority of humans in action, even in view of the human tasks of promoting science and research.

    Full Text Available Abstract Background The 11S globulin Sin a 2 is a marker to predict severity of symptoms in mustard allergic patients. The potential implication of Sin a 2 in cross-reactivity with tree nuts and peanut has not been investigated so far. In this work, we studied at the IgG and IgE level the involvement of the 11S globulin Sin a 2 in cross-reactivity among mustard, tree nuts and peanut. Methods Eleven well-characterized mustard-allergic patients sensitized to Sin a 2 were included in the study. A specific anti-Sin a 2 serum was obtained in rabbit. Skin prick tests (SPT, enzyme-linked immunosorbent assay (ELISA, immunoblotting and IgG or IgE-inhibition immunoblotting experiments using purified Sin a 2, Sin a 1, Sin a 3, mustard, almond, hazelnut, pistachio, walnut or peanut extracts were performed. Results The rabbit anti-Sin a 2 serum showed high affinity and specificity to Sin a 2, which allowed us to demonstrate that Sin a 2 shares IgG epitopes with allergenic 11S globulins from tree nuts (almond, hazelnut, pistachio and walnut but not from peanut. All the patients included in the study had positive skin prick test to tree nuts and/or peanut and we subdivided them into two different groups according to their clinical symptoms after ingestion of such allergenic sources. We showed that 11S globulins contain conserved IgE epitopes involved in cross-reactivity among mustard, tree nuts and peanut as well as species-specific IgE epitopes. Conclusions The allergenic 11S globulin Sin a 2 from mustard is involved in cross-reactivity at the IgE level with tree nuts and peanut. Although the clinical relevance of the cross-reactive IgE epitopes present in 11S globulins needs to be investigated in further detail, our results contribute to improve the diagnosis and management of mustard allergic patients sensitized to Sin a 2.

  2. Biofilm formation by Bacillus subtilis requires an endoribonuclease-containing multisubunit complex that controls mRNA levels for the matrix gene repressor SinR.

    Biofilm formation by Bacillus subtilis is largely governed by a circuit in which the response regulator Spo0A turns on the gene for the anti-repressor SinI. SinI, in turn, binds to and inactivates SinR, a dedicated repressor of genes for matrix production. Mutants of the genes ylbF, ymcA and yaaT are blocked in biofilm formation, but the mechanism by which they act has been mysterious. A recent report attributed their role in biofilm formation to stimulating Spo0A activity. However, we detect no measurable effect on the transcription of sinI. Instead, we find that the block in biofilm formation is caused by an increase in the levels of SinR and of its mRNA. Evidence is presented that YlbF, YmcA and YaaT interact with, and control the activity of, RNase Y, which is known to destabilize sinR mRNA. We also show that the processing of another target of RNase Y, cggR-gapA mRNA, similarly depends on YlbF and YmcA. Our work suggests that sinR mRNA stability is an additional posttranscriptional control mechanism governing the switch to multicellularity and raises the possibility that YlbF, YmcA and YaaT broadly regulate mRNA stability as part of an RNase Y-containing, multi-subunit complex.

Se utilizó una radiómetro UV-B, que mide la radiación solar en el rango espectral 280-315 nm, y un radiómetro RUV, que mide la radiación solar en el rango espectral 280-385 nm. La dependencia entre entre UV-B y RUV también fue investigada, y se encontró un excelente grado de asociación entre ambas. Además se detalló que UV-B representa solamente un 5,4% de RUV, a pesar de que UV-B es mil veces más potente que UV-A. Los valores de UV-B medidos in situ fueron comparados con los valores predichos por un modelo atmosférico espectral, el cual utiliza como datos de entrada: la hora del día, la latitud, la altitud, el albedo superficial, la distancia Tierra-Sol, la turbiedad atmosférica y el ozono atmosférico. La comparación entre los valores medidos y predichos dio resultados satisfactorios.

    Full Text Available El Modelo Bifactorial de Afectividad de Watson y Tellengen se ha postulado para la diferenciación de la ansiedad y la depresión en Europa y Norteamérica, pero no se han reportado estudios en población cubana de edad media. El objetivo de esta investigación fue investigar la Afectividad Positiva (AP y la Afectividad Negativa (AN en personas sin psicopatología, con sintomatología predominantemente ansiosa, depresiva o mixta. La muestra fue de 219 personas; 19,2% con sintomatología ansiosa, 17,8% depresiva, 23,7% mixta y el resto sin síntomas. Se utilizó el Inventario de Afecto Positivo y Negativo (PANAS para estudiar la afectividad y la Escala de Ansiedad y Depresión de Goldberg (EADG para diferenciar los subgrupos diagnósticos. Se utilizó el ANOVA de un factor con el Método de la Diferencia Significativa Honesta de Tukey para establecer las diferencias. Se encontró que la AP era menor en los depresivos tal y como predice el Modelo, pero no se cumplió la predicción de que la AP diferenciaría a los ansiosos de las personas sin síntomas, y se encontró que en el grupo con sintomatología mixta había mayor AN y menor AP que en los otros subgrupos patológicos, lo cual alerta sobre la necesidad de evaluar los modelos desarrollados en otras culturas.

    单纯依赖单一的导航手段难满足高精度的导航需求,因此,将捷联惯性导航系统(SINS)、全球卫星导航系统(GNSS)有效组合,实现优势互补。SINS/GNSS 组合导航系统的数据处理一般采用卡尔曼滤波实现,当组合导航系统模型足够准确时,滤波性能较好,当导航系统模型存在误差或发生变化时,新的量测值对滤波估计值的修正作用下降,而旧的量测值的修正作用相对上升,从而导致滤波精度下降。针对上述问题,基于集中式卡尔曼滤波结构的SINS/GNSS组合导航系统,本文提出一种新方法,新方法在梯度方向上进行估计迭代,从而修正模型误差对滤波精度的影响,提高导航定位精度。实验结果表明,当导航系统模型和量测方程存在误差或发生变化时,新方法仍可以为导航系统提供有效的定位精度,满足高空长航时系统需求。%Relying on a single method of navigation is difficult to meet the high precision requirement. Thus, the strap-down inertial navigation system (SINS) and global navigation satellite system (GNSS) integrated with complementary advantages can better meet the performance requirement. The SINS/GNSS integrated navigation system usually uses the Kalman filter to realize the data processing. When the integrated navigation system model is accurate enough, the filtering performance is good; when the navigation system model has error or change, the correction function of new measurement decrease, but the old measurement increase relatively. In order to solve the above problem, based on the SINS/GNSS integrated navigation system with the centralized Kalman filtering structure, this paper presents a new method which can process the data by estimation iterating on the gradient direction, correct the model error and improve the navigation positioning precision. The experimental results show that the new method can provide effective

  17. The stress-related, rhizobial small RNA RcsR1 destabilizes the autoinducer synthase encoding mRNA sinI in Sinorhizobium meliloti.

    2016-05-03

    Quorum sensing is a cell density-dependent communication system of bacteria relying on autoinducer molecules. During the analysis of the post-transcriptional regulation of quorum sensing in the nitrogen fixing plant symbiont Sinorhizobium meliloti, we predicted and verified a direct interaction between the 5'-UTR of sinI mRNA encoding the autoinducer synthase and a small RNA (sRNA), which we named RcsR1. In vitro, RcsR1 prevented cleavage in the 5'-UTR of sinI by RNase E and impaired sinI translation. In line with low ribosomal occupancy and transcript destabilization upon binding of RcsR1 to sinI, overproduction of RcsR1 in S. meliloti resulted in lower level and shorter half-life of sinI mRNA, and in decreased autoinducer amount. Although RcsR1 can influence quorum sensing via sinI, its level did not vary at different cell densities, but decreased under salt stress and increased at low temperature. We found that RcsR1 and its stress-related expression pattern, but not the interaction with sinI homologs, are conserved in Sinorhizobium, Rhizobium and Agrobacterium. Consistently, overproduction of RcsR1 in S. meliloti and Agrobacterium tumefaciens inhibited growth at high salinity. We identified conserved targets of RcsR1 and showed that most conserved interactions and the effect on growth under salt stress are mediated by the first stem-loop of RcsR1, while its central part is responsible for the species-specific interaction with sinI. We conclude that RcsR1 is an ancient, stress-related riboregulator in rhizobia and propose that it links stress responses to quorum sensing in S. meliloti.

  18. Thickness-dependent dielectric breakdown and nanopore creation on sub-10-nm-thick SiN membranes in solution

    2017-01-01

    Recently, dielectric breakdown of solid-state membranes in solution has come to be known as a powerful method for fabricating nanopore sensors. This method has enabled a stable fabrication of nanopores down to sub-2 nm in diameter, which can be used to detect the sizes and structures of small molecules. Until now, the behavior of dielectric breakdown for nanopore creation in SiN membranes with thicknesses of less than 10 nm has not been studied, while the thinner nanopore membranes are preferable for nanopore sensors in terms of spatial resolution. In the present study, the thickness dependence of the dielectric breakdown of sub-10-nm-thick SiN membranes in solution was investigated using gradually increased voltage pulses. The increment in leakage current through the membrane at the breakdown was found to become smaller with a decrease in the thickness of the membrane, which resulted in the creation of smaller nanopores. In addition, the electric field for dielectric breakdown drastically decreased when the thickness of the membrane was less than 5 nm. These breakdown behaviors are quite similar to those observed in gate insulators of metal-oxide-semiconductor devices. Finally, stable ionic-current blockades were observed when single-stranded DNA passed through the nanopores created on the membranes with thicknesses of 3-7 nm.

El objetivo de este estudio, realizado en Barcelona (España durante el mes de mayo de 2013, es testear la percepción de 25 valores en siete spots televisivos de alimentación (con y sin estrategias de imagen corporal en 139 jóvenes con y sin trastornos de la conducta alimentaria (TCA. Los resultados muestran que solo el grupo de jóvenes con TCA considera que los spots con una estrategia comercial basada en la imagen corporal influyen muy negativamente en valores como salud, bienestar, familia y esfuerzo. En cambio, se ha observado una gran coincidencia entre los dos grupos cuando se evalúa el resto de los spots. Estos resultados señalan que los jóvenes universitarios españoles de hoy han aceptado como normal un canon de belleza basado en el orden social y económico, mientras que los jóvenes en tratamiento por desórdenes alimenticios sí han aprendido a decodificar este tipo de mensajes.

The signal samples of B0/B¯ 0 → J/ψKS and B0/B¯0 → ψ(2 S)KS are extracted from the 110 pb −1 of p- p¯ collisions at s = 1.8 TeV. The flavor of the neutral B mesons is identified at the time of production by three tagging algorithms: a same-side tag, a soft-lepton tag, and an opposite-side- jet tag. The opposite-side-jet tag is a combination of the previously used jet-charge tag and a few new tags. A generic algorithm is developed to combine the tags to improve the tagging performance. A maximum likelihood fitting method is used to determine sin 2β = 0.91+0.37-0.36 . The uncertainties are improved over the previous CDF measurement. The value is consistent with the standard model prediction of a large positive CP asymmetry in this decay mode. It is also consistent with the world average valu...

    This paper presents the second part of a study aiming at the error state selection in Kalman filters applied to the stationary self-alignment and calibration (SSAC) problem of strapdown inertial navigation systems (SINS). The observability properties of the system are systematically investigated, and the number of unobservable modes is established. Through the analytical manipulation of the full SINS error model, the unobservable modes of the system are determined, and the SSAC error states (except the velocity errors) are proven to be individually unobservable. The estimability of the system is determined through the examination of the major diagonal terms of the covariance matrix and their eigenvalues/eigenvectors. Filter order reduction based on observability analysis is shown to be inadequate, and several misconceptions regarding SSAC observability and estimability deficiencies are removed. As the main contributions of this paper, we demonstrate that, except for the position errors, all error states can be minimally estimated in the SSAC problem and, hence, should not be removed from the filter. Corroborating the conclusions of the first part of this study, a 12-state Kalman filter is found to be the optimal error state selection for SSAC purposes. Results from simulated and experimental tests support the outlined conclusions.

  4. Sin/cosine encoder interpolation methods: encoder to digital tracking converters for rate and position loop controllers

    Pointing and tracking applications usually require relative gimbal angles to be measured for reporting and controlling the line-of-sight angular position. Depending on the application, angular resolution and/or accuracy might jointly or independently determine the angle transducer requirements. In the past decade, encoders have been increasingly taking the place of inductive devices where the measurement of angles over a wide range is required. This is primarily due to the fact that encoders are now achieving very high resolution in smaller sizes than was previously possible. These advances in resolution are primarily due to improved encoder disk and detector technology along with developments in interpolation techniques. Measurement accuracy, on the other hand, is primarily determined by mounting and bearing eccentricity as it is with all angular measurement devices. For very demanding accuracy requirements, some type of calibration of the assembled system may be the only solution, in which case transducer repeatability is paramount. This paper describes a unique encoder-to-digital tracking converter concept for improving interpolation of optical encoders. The new method relies on Fraunhofer diffraction models to correct the non-ideal sin/cos outputs of the encoder detectors. Diffraction model concepts are used in the interpolation filters to predict the phase of non-ideal sin and cosine encoder outputs. The new method also minimizes many of the open loop pre-processing requirements and assumptions that limit interpolation accuracy and rate loop noise performance in ratiometric tracking converter designs.

    Here the integration of a tube-shaped Pirani gauge with a SiN thin-film encapsulation process is presented. The tube geometry gives the sensor a very low detection limit with a small footprint, since the tube is buried under the silicon surface. The Pirani tube is very suitable for in situ evaluation of MEMS vacuum packaging. Moreover, since the Pirani gap is all around the tube and deep below the silicon surface, the deflection of the encapsulation shell is not a concern and wafer-level measurement of the device is possible. Pirani tubes with different lengths are encapsulated inside SiN micropackages in order to measure the resulting vacuum level achieved after the encapsulation step. The longest tube shows a detection limit of 0.1 Pa for a noise level of 50 μV and it has a footprint of only 0.006 mm2. The pressure inside the sealed micropackage was extracted to be 0.7 kPa. Furthermore, the pressure is monitored over time to evaluate the hermeticity of the packages. A leak rate of 8× 10-18 Pa m3 s-1 was measured over four months time.

    The prediction of the effective electroweak mixing angle $\\sin^2\\theta_{\\rm eff}^{\\rm b}$ in the Standard Model at two-loop accuracy has now been completed by the first calculation of the bosonic two-loop corrections to the $Z{\\bar b}b$ vertex. Numerical predictions are presented in the form of a fitting formula as function of $M_Z, M_W, M_H, m_t$ and $\\Delta{\\alpha}$, ${\\alpha_{\\rm s}}$. For central input values, we obtain a relative correction of $\\Delta\\kappa_{\\rm b}^{(\\alpha^2,\\rm bos)} = -0.9855 \\times 10^{-4}$, amounting to about a quarter of the fermionic corrections, and corresponding to $\\sin^2\\theta_{\\rm eff}^{\\rm b} = 0.232704$. The integration of the corresponding two-loop vertex Feynman integrals with up to three dimensionless parameters in Minkowskian kinematics has been performed with two approaches: (i) Sector decomposition, implemented in the packages FIESTA 3 and SecDec 3, and (ii) Mellin-Barnes representations, implemented in AMBRE 3/MB and the new package MBnumerics.

    Full Text Available Abstract Background To elucidate the mechanism by which local delivery of 3-morpholino-sydnonimine (SIN-1 affects intimal hyperplasia after percutaneous transluminal coronary angioplasty (PTCA. Methods Porcine coronary arteries were treated with PTCA and immediately afterwards locally treated for 5 minutes, with a selective cytosolic guanylate cyclase inhibitor, 1 H-(1,2,4oxadiazole(4,3-alphaquinoxaline-1-one (ODQ + SIN-1 or only SIN-1 using a drug delivery-balloon. Arteries were angiographically depicted, morphologically evaluated and analyzed after one and eight weeks for actin, myosin and intermediate filaments (IF and nitric oxide synthase (NOS contents. Results Luminal diameter after PCI in arteries treated with SIN-1 alone and corrected for age-growth was significantly larger as compared to ODQ + SIN-1 or to controls (p Conclusions After PTCA local delivery of high concentrations of the NO donor SIN-1 for 5 minutes inhibited injury induced neointimal hyperplasia. This favorable effect was abolished by inhibition of guanylyl cyclase indicating mediation of a cyclic guanosine 3',5'-monophosphate (cGMP-dependent pathway. The momentary events at the time of injury play crucial role in the ensuring development of intimal hyperplasia.

  11. The sinR ortholog PGN_0088 encodes a transcriptional regulator that inhibits polysaccharide synthesis in Porphyromonas gingivalis ATCC 33277 biofilms.

    Directory of Open Access Journals (Sweden)

    Reiko Yamamoto

    Full Text Available Biofilm-forming cells are distinct from well characterized planktonic cells and aggregate in the extracellular matrix, the so-called extracellular polymeric substances (EPS. The sinR gene of Bacillus subtilis encodes a transcriptional regulator that is known to be involved in the biosynthesis of EPS in biofilms. Porphyromonas gingivalis inhabits the subgingival and extraradicular biofilm of humans and is one of the primary pathogens that cause progressive marginal and refractory apical periodontitis. Furthermore, P. gingivalis possesses PGN_0088, which encodes a putative ortholog of B. subtilis sinR. Here, we investigated the role of PGN_0088 (sinR on biofilm formation. P. gingivalis strains formed biofilms on saliva-coated glass surfaces in phosphate buffered saline. Quantitative analysis indicated that the biofilm of the sinR null mutant consisted of dense exopolysaccharide. Microscopic observations showed that the increased levels of exopolysaccharide produced by the sinR mutant changed the morphology of the EPS to a mesh-liked structure. Furthermore, physical analyses suggested that the enrichment of exopolysaccharide in the EPS enhanced the resistance of the biofilm to hydrodynamic shear force. The results presented here demonstrate sinR plays important roles in the ability of P. gingivalis strain ATCC 33277 to act as a negative mediator of exopolysaccharide accumulation and is indirectly associated with the structure of the EPS and the force of its adhesion to surfaces.

    The possibility of forming GaN layers on Ga-implanted SiN surfaces was investigated using electron cyclotron resonance-assisted molecular beam epitaxy (MBE). It is found that the GaN layer initially formed on the SiN surface by Ga implantation at room temperature was amorphous-like, but become to polycrystalline after annealing at 650 deg. C for 3 min in vacuum. After the MBE growth of GaN, a grain structure of h-GaN was observed on the Ga-implanted SiN surface. The crystallinity of the GaN grown was, however, decreased upon increasing the Ga ion fluence on the SiN surface, which might be due, at least partly, to the formation of Ga clusters by the excess Ga implanted. The present results indicate the possibility of forming patterned GaN layers on SiN by selective Ga implantation on the SiN substrate, using a focused ion beam.

[Spanish] Actualmente existe una problematica por el uso inadecuado e ineficiente de la energia electrica en los sistemas de alimentacion, esta problematica se va complicando aun mas con el paso del tiempo, debido a la proliferacion de equipos electronicos que no incorporan alguna solucion para dicha problematica. Esto ha ocasionado una tendencia hacia el desarrollo de sistemas que procesen con mayor eficiencia ({eta}) la energia electrica. Ademas para hacer un buen uso de la energia, se les disena para que puedan corregir el factor de potencia (FP) y por lo tanto reducen la contaminacion de armonicos en la red; los cuales provocan fallas o destruccion en otros equipos electronicos. Adicionalmente se les puede disenar para obtener una buena respuesta dinamica, lo cual asegura que podran contrarrestar eficientemente cambios de carga. La caracteristica no lineal que esta presente en todas las fuentes de alimentacion, que basan su entrada en una etapa de rectificacion y filtrado, provocan un bajo factor de potencia (FP) y una alta distorsion armonica total (THD). El factor es contaminar la red electrica, lo cual puede provocar fallas o descomposturas de otros equipos. Desde hace aproximadamente 15 anos la preocupacion por resolver este problema de uso inadecuado de la energia ha tomado importancia, desarrollando convertidores que corrigen el FP (pre-regulador) y que tradicionalmente se conectan en cascada con la tipica etapa de conversion de corriente directa a corriente directa (CD-CD) usada para regular la tension; esta solucion tiene una baja eficiencia ({eta}) y alto costo, por el exceso de componentes conectados en cascada. Sin embargo la respuesta dinamica (RD) es adecuada ya que se cuenta con etapas separadas para la correccion del FP y la regulacion. A partir de una revision del estado del arte, en

    Full Text Available A vertex v ∈ V (G is said to distinguish two vertices x, y ∈ V (G of a graph G if the distance from v to x is di erent from the distance from v to y. A set W ⊆ V (G is a total resolving set for a graph G if for every pair of vertices x, y ∈ V (G, there exists some vertex w ∈ W − {x, y} which distinguishes x and y, while W is a weak total resolving set if for every x ∈ V (G−W and y ∈ W, there exists some w ∈ W −{y} which distinguishes x and y. A weak total resolving set of minimum cardinality is called a weak total metric basis of G and its cardinality the weak total metric dimension of G. Our main contributions are the following ones: (a Graphs with small and large weak total metric bases are characterised. (b We explore the (tight relation to independent 2-domination. (c We introduce a new graph parameter, called weak total adjacency dimension and present results that are analogous to those presented for weak total dimension. (d For trees, we derive a characterisation of the weak total (adjacency metric dimension. Also, exact figures for our parameters are presented for (generalised fans and wheels. (e We show that for Cartesian product graphs, the weak total (adjacency metric dimension is usually pretty small. (f The weak total (adjacency dimension is studied for lexicographic products of graphs.

    Full Text Available Photovoltaic (PV inverters have a very important role in the energy market, therefore they must possess excellent characteristics regarding cost and reliability. The PV structure most often used in the conversion stage of solar energy system includes a Low Frequency Transformer (LFT which provides galvanic isolation, but on the other hand reduces the overall efficiency and increases the total size and cost of the system. An alternative to reduce the size of the system and the losses, is to use a High Frequency Transformer (HFT, the problem in this case is that additional power stages must be included in the system. The additional stages increase the power losses in the conversion process, as a consequence the efficiency of the system is reduced. Therefore the tendency is to remove the transformer in order to increase the efficiency and reduce the cost. A security problem regarding common mode currents arise when the LFT or HFT is omitted. In this paper an inverter topology to deal with the problem of the common mode currents is proposed. Numerical results are performed in order to prove the performance of the topology regarding efficiency and Common Mode Voltage (CMV issues

    Alloriite, a new mineral species, has been found in volcanic ejecta at Mt. Cavalluccio (Campagnano municipality, Roma province, Latium region, Italy) together with sanidine, biotite, andradite, and apatite. The mineral is named in honor of Roberto Allori (b. 1933), an amateur mineralogist and prominent mineral collector who carried out extensive and detailed field mineralogical investigations of volcanoes in the Latium region. Alloriite occurs as short prismatic and tabular crystals up to 1.5 × 2 mm in size. The mineral is colorless, transparent, with a white streak and vitreous luster. Alloriite is not fluorescent and brittle; the Mohs’ hardness is 5. The cleavage is imperfect parallel to {10overline 1 0}. The density measured with equilibration in heavy liquids is 2.35g/cm3 and calculated density ( D calc) is 2.358 g/cm3 (on the basis of X-ray single-crystal data) and 2.333 g/cm3 (from X-ray powder data). Alloriite is optically uniaxial, positive, ω = 1.497(2), and ɛ = 1.499(2). The infrared spectrum is given.

In this scheme, the Kalman filtering is done firstly and based on this, the backward smoothing iteration is performed for correcting the filter’s results during each synthetic aperture moment. The results of numerical simulation and flight-test data processing show that the scheme can effectively improve the precision of estimates of the motion parameter in the synthetic aperture moment.

    Full Text Available Por la ubicuidad de las micobacterias no tuberculosas (MNTBs en el ambiente y la alta prevalencia observada en VIH positivos cuya interpretación era confusa, se realizó un estudio para determinar la prevalencia de MNTBs en la población general y saber cuál era la naturaleza del hallazgo de MNTBs en VIH positivos. Se comparó un grupo de 101 individuos VIH positivos del Servicio Integrado de Enfermedades Infecciosas del Instituto de Seguro Social y 100 individuos controles sin riesgo para infección por VIH. En ambos grupos se tomaron muestras de jugo gástrico para tinción y cultivo. La prevalencia de micobacterias en los VIH positivos fue 7% así: TBC, 2%; y MNTBs, 5%. Las MNTBs aisladas fueron: M. gordonae, 2; M. szulgai, 1; M. fortuitum, 1; y M. avium, 1, todas tan sólo en el cultivo y en pacientes de estadío IV; sin embargo, apenas un caso se asoció con enfermedad. En los controles la prevalencia fue 6%: 1 micobacteria se encontró en el Ziehl Neelsen pero no se aisló en cultivo y las 5 restantes que se aislaron en cultivo, eran M. szulgai; ninguna se asoció con enfermedad. No se encontró asociación entre pH, mucosidad, celularidad, leucocitos y otras características del jugo gástrico en las muestras de pacientes con y sin MNTBs. Por consiguiente, se pudo concluir que la prevalencia de MNTBs fue igual tanto en VIH positivos como en el grupo de las personas con factores de riesgo a la infección, población general y bastante menor que la encontrada en un estudio previo. En los VIH positivos la presencia de MNTBs se asoció con estadíos avanzados de la infección y con el consumo de antibióticos orales. El hallazgo de MNTBs obedece a una exposición al ambiente contaminado; por lo general se trata de colonizaciones y su significado clínico en individuos con infección por el VIH está supeditado a las condiciones inmunológicas del enfermo.

    A quantum mechanical study of small silicon nitride clusters (SinNm, n + m ⩽ 4) was performed for both the ground and excited electronic states. The diatomic SiN as well as the tri-atomic SiN2 and Si2N clusters were chosen as our benchmark systems for an extensive investigation of the various methods, functionals and basis sets. Among the methods investigated for the ground-state geometry optimization and vibrational frequency calculations, density functional theory (DFT) with the B3LYP functional was found to be the best performed method overall. For the basis set, 6-311G(d) is chosen for its nice balance between accuracy and efficiency in time. At the B3LYP/6-311G(d) level of theory, the most stable isomers of SiN2, Si2N, SiN3, Si3N and Si2N2, were determined to be the triplet (3Σ-) asymmetric linear isomer (Sisbnd Ndbnd N), the doublet (2Πg) symmetric linear isomer (Sidbnd Ndbnd Si), the doublet (2A‧) nonlinear isomer (Sidbnd Nsbnd Ndbnd N), the doublet (2B1) Y-type isomer, and the singlet (1Σg+) symmetric linear isomer (Sidbnd Ndbnd Ndbnd Si), respectively. Analysis of the relative energies of various stable isomers shows that Nsbnd N bonding is the most favored one and Sisbnd Si bonding is least favored. Due to its good performance in predicting the electronic transitions from the X2Σ+ ground state of SiN to three low-lying excited states A2 Π , B2Σ+ , and D2 Π , TDDFT/B3LYP/6-311G(d) was chosen over EOMCCSD/6-311G(d) for the excited state calculations. The first ten electronic transitions for the most stable isomers of all SinNm (n + m ⩽ 4) clusters were calculated.

    We have studied nonisoscalarity and medium effects in the extraction of weak mixing angle using Paschos and Wolfenstein relation in the iron nucleus. Paschos and Wolfenstein(PW) relation is valid for an isoscalar target. We have modified the PW relation for nonisoscalar target as well as incorporated the medium effects like Pauli blocking, Fermi motion, nuclear binding energy and pion rho cloud contributions. In our calculations we have used the relativistic nuclear spectral function which includes nucleon correlations. Finally local density approximation is applied to translate the numerical results to the finite nuclei. We have studied the dependence of sin{sup 2}θ{sub W} on Bjorken variables x and y, four momentum transfer square (Q{sup 2}), energy of the neutrino and antineutrino, and effect of excess neutrons over protons in the nuclear target.

    This paper reports an updated measurement of the Standard Model CP violation parameter $\\sin2\\beta$ using the CDF Detector at Fermilab. The entire Run I data sample of 110 pb$^{-1}$ of proton antiproton collisions at $\\sqrt{s}=1.8 TeV$ is used to identify a signal sample of $\\sim 400$ $B \\to J/\\psi K^0_S$ events, where $J/\\psi \\to \\mu^+\\mu^-$ and $K_S^0 \\to \\pi^+\\pi^-$. The flavor of the neutral B meson is identified at the time of production by combining information from three tagging algorithms: a same-side tag, a jet-charge tag, and a soft-lepton tag. A maximum likelihood fitting method is used to determine is consistent with the Standard Model prediction, based upon existing measurements, of a large positive CP violating asymmetry in this decay mode.

    Generation of chaos from nonlinear optical systems with an optical or electronic feedback has been studied for several years. Such chaotic signals have an important application in providing secure encryption in free-space optical communication systems. Lyapunov exponent is an important parameter for analysis of chaos generated by a nonlinear system. The Lyapunov exponent of a class of a nonlinear optical system showing a nonlinear transfer characteristics of the form sin2(x) is determined and calculated in this paper to understand the dependence of the chaotic response on the system parameters such as bias, feedback gain, input intensity and initial condition exciting the optical system. Analysis of chaos using Lyapunov exponent is consistent with bifurcation analysis and is useful in encrypting data signal.

    Full Text Available El caso de los padres viudos ha sido muy poco estudiado. De acuerdo con las estadísticas, es reducido el porcentaje de los hombres en tal condición que deciden criar a sus hijos sin el apoyo de una nueva pareja. Al respecto, hay varias fuentes formales e informales que señalan que los hombres no pueden llevar con éxito tal tarea. En el presente estudio se analizan los puntos de coincidencia y discrepancia entre estas ideas y las experiencias compartidas por los propios padres viudos, con lo que se espera ofrecer información que permita una mayor comprensión de su situación personal y su impacto en la familia. Se entrevistó a siete padres viudos que habían criado a sus hijos sin el auxilio de una pareja al menos durante diez años. Cuando enviudaron, tenían entre 26 y 48 años de edad y habían procreado de dos a tres hijos. Se analizaron los datos de acuerdo al método fenomenológico. En los resultados se halló que estos hombres habían mantenido sus emociones hacia sus esposas; fueron presionados socialmente para que volvieran a casarse; recibieron menos apoyos por razones de género; utilizaron otros modelos de crianza, además del que les dieron sus propios padres; pasaron a segundo término sus conflictos y necesidades personales; manifestaron un uso racional del dinero y la disciplina; le dieron importancia a los aspectos emocionales de sus hijos, y consideraron exitosa y satisfactoria la manera en que los educaron. Se concluye abordando la necesidad de instrumentar acciones de tipo psicológico, social y económico a favor de estos hombres y sus familias.

    Numerous genes are associated with neurodevelopmental disorders such as intellectual disability and autism spectrum disorder (ASD), but their dysfunction is often poorly characterized. Here we identified dominant mutations in the gene encoding the transcriptional repressor and MeCP2 interactor switch-insensitive 3 family member A (SIN3A; chromosome 15q24.2) in individuals who, in addition to mild intellectual disability and ASD, share striking features, including facial dysmorphisms, microcephaly and short stature. This phenotype is highly related to that of individuals with atypical 15q24 microdeletions, linking SIN3A to this microdeletion syndrome. Brain magnetic resonance imaging showed subtle abnormalities, including corpus callosum hypoplasia and ventriculomegaly. Intriguingly, in vivo functional knockdown of Sin3a led to reduced cortical neurogenesis, altered neuronal identity and aberrant corticocortical projections in the developing mouse brain. Together, our data establish that haploinsufficiency of SIN3A is associated with mild syndromic intellectual disability and that SIN3A can be considered to be a key transcriptional regulator of cortical brain development.

    Retroviral vectors containing internal promoters, chromatin insulators, and self-inactivating (SIN) long terminal repeats (LTRs) may have significantly reduced genotoxicity relative to the conventional retroviral vectors used in recent, otherwise successful clinical trials. Large-scale production of such vectors is problematic, however, as the introduction of SIN vectors into packaging cells cannot be accomplished with the traditional method of viral transduction. We have derived a set of packaging cell lines for HIV-based lentiviral vectors and developed a novel concatemeric array transfection technique for the introduction of SIN vector genomes devoid of enhancer and promoter sequences in the LTR. We used this method to derive a producer cell clone for a SIN lentiviral vector expressing green fluorescent protein, which when grown in a bioreactor generated more than 20 L of supernatant with titers above 10(7) transducing units (TU) per milliliter. Further refinement of our technique enabled the rapid generation of whole populations of stably transformed cells that produced similar titers. Finally, we describe the construction of an insulated, SIN lentiviral vector encoding the human interleukin 2 receptor common gamma chain (IL2RG) gene and the efficient derivation of cloned producer cells that generate supernatants with titers greater than 5 x 10(7) TU/mL and that are suitable for use in a clinical trial for X-linked severe combined immunodeficiency (SCID-X1).

    Photoluminescence (PL) and colorimetric properties of white-light emission SrA12Si2O8:Eu2+,Mn2+ phosphor were tuned effectively through incorporating Si-N bond to the host in the form of Si3N4. A maximum solubility of Si-N bond in SrA12-xSi2+xO8-xNx was estimated theoretically to be in a value of x=1.0. Under 365 nm irradiation, a distinct red-shift of blue band emission from 406 to 473 nm for Eu2+ and an enhancement of yellow band emission peaked at ~565 nm for Mn2+ were observed with the increase of Si-N content. These effects resulted from partial substitution of Si-N for All-O1 and A14-O2 sites in SrA12Si2O8 lattice. Eventually, a white emission with CIE chromaticity coordinates (0.287, 0.337) and color rendering index (CRI) 78.3 for SrAl2Si2O8:Eu2+,Mn2+ phosphor were achieved upon optimization to a suitable amount of Si-N.

    Full Text Available The public narrative generally frames teachers unions and the charter movement as mistrustful opponents locked in an unresolved impasse. There is little scholarly literature to correct this simplistic narrative of the relationship between charters and unions. This article examines the teachers union- charter relationship through a recent case of active and sometimes bitter charter politics: the fight to lift the charter cap in New York state in 2006 and 2007. This study examines the dynamics of the relationship through an analysis of media coverage of the New York caps fight and interviews with nearly 30 experts with varied views on charter schooling and from a wide range of professional backgrounds. The New York case suggests that ultimately, creating strong unions and effective charter schooling depends on these two sides finding common ground. En discusiones publicas es frecuente colocas a los sindicatos docentes y a el movimiento de escuelas “charter” como adversarios, desconfiados, encerrados en un callejón sin salida. Es escasa la literatura académica que corrija esa narrativa simplista sobre la relación entre las escuelas “charter” y los sindicatos. Este artículo examina la relación entre los sindicatos de maestros y las escuelas “charter” por medio de un caso reciente de política, activa y a veces amarga del caso “charter”: la lucha en Nueva York durante los años 2006 y 2007 para eliminar los límites a las escuelas “charter” en ese estado. Este estudio examina la dinámica de la relación a través de un análisis de la cobertura periodística en la lucha de límites en Nueva York. Incluye también entrevistas con casi 30 expertos con perspectivas diversas sobre las escuelas “charter” y con una amplia variedad de experiencias profesionales. El caso de Nueva York sugiere esencialmente que la creación de sindicatos poderosos y un modelo de escolarización “charter” efectiva depende de que los dos lados

[Italian] La gastroplastica verticale secondo Mason rappresenta una delle tecniche piu' utilizzate nel trattamento dell'obesita' patologica in quanto ha semplice esecuzione, buoni risultati e scarsa incidenza di complicanze a distanza. Nel presente lavoro venogno presentati i risultati del controllo radiologico postoperatorio condotto su 322 pazienti sottoposti a gastroplastica verticale secondo Mason modificata. In 322 pazienti sottoposti a gastroplastica verticale secondo Mason modificata sono state valutate mediante studio radiologico con pasto semiliquido e tecnica con mdc semplice le caratteristiche morfologiche, funzionali e volumetriche della tasca gastrica e le eventuali complicanze dell'intervento. Di questi 322 pazienti 272 erano femmine con eta' compresa tra 17 e 69 anni (media 37) e 50 maschi con eta' compresa tra 19 a 64 anni (media 36); il peso medio era di 124 kg (con intervallo da 78 a 218). Solo nei pochi casi in cui e' risultata necessaria la valutazione dettagliata della mucosa del neostomaco e' stato utilizzato il doppio mdc on minime dosi di polvere effervescente. La valutazione e' stata effettuata dopo uno e 12 mesi dall'intervento. Controlli al di fuori di questo protocollo sono stati effettuati solo su precisa indicazione clinica per sospetta insorgenza di complicanze compreso il non adeguato calo ponderale. Nella nostra serie si sono osservate 9 complicanze precoci: edema persistente dello pseudopiloro (8 casi) ed emorragia endogastrica (un caso) e 8 complicanze tardive: aderenza dello pseudopiloro al letto della colecisti (un caso), formazione di pseudo-diverticolo della parete posteriore del neostomaco (un caso), orizzontalizzazione del neostomaco (4 casi), deiscenza della sutura lineare (2 casi).

    在不增加辅助系统的情况下,针对捷联惯性导航/全球定位组合导航系统(SINS/GPS)在GPS信号不可用时,其定位精度产生较大退化的问题,提出了遗传算法优化的径向基函数神经网络辅助组合导航系统定位的方法。当 GPS 信号可用时,采用遗传算法对径向基函数神经网络进行优化训练;当 GPS信号不可用时,利用遗传算法优化后的径向基函数神经网络预测卡尔曼滤波器量测输入中的速度误差信息,使得卡尔曼滤波器能够继续工作并提供速度校正量。跑车实验表明,通过对速度进行误差补偿能够有效地修正位置误差,以GPS信号断开180 s的结果作分析,纯SINS模式的东向和北向位置误差分别为35.1 m和38.8 m,而本文所提方法的误差分别为10.5 m和7.2 m,其定位精度提高较为显著。%The accuracy of SINS/GPS would have larger degradation as time going on during GPS outages when without other aided systems. To solve this problem, a radial basis function neural network (RBFNN) method based on genetic algorithm optimization was proposed to aid the SINS/GPS navigation and positioning. The critical parameters of RBFNN were trained by genetic algorithm optimization(GA-RBFNN) when the GPS signals were available. And the information of velocity errors in the measurement inputs of Kalman filtering(KF) during the GPS outages were predicted by using the GA-RBFNN, which allow the KF to continue functioning and provide velocity updates. Experimental results show that the position error can be effectively corrected by compensating the velocity error. For the case of 180 s GPS outages, the east/north position errors with and without using the proposed compensation method are 10.5/7.2 m and 35.1/38.8 m, respectively, showing that the positioning accuracy has significant improvement.

El balso blanco (Heliocarpus americanus L. Sin. H. popayanensis Hook & Arn. es la especie más usada en procesos de clarificación de la panela en Antioquia y las zonas cañeras húmedas colombianas. Pero la extracción de la corteza de árboles obtenidos de la regeneración natural comienza a ser insostenible, por el daño causado a los individuos y la presión creciente a este recurso. La prohibición del uso de sustancias químicas en procesos de clarificación de panela ha aumentado la demanda de la corteza del balso blanco. En este trabajo se estimó el enraizamiento de estacas juveniles de balso blanco, por propagadores de subirrigación. Se realizaron dos experimentos, utilizando ácido anaftalenacético (ANA. En el primero se evaluó el efecto del transporte, cicatrizante y sustrato sobre el enraizamiento de las estacas de balso blanco. El mejor medio de transporte fue en cristales de hidrogel para mantener la humedad de las estacas, sin utilizar cicatrizante y sembrándolas en el sustrato tierra (55 % de enraizamiento. En el segundo se analizó la influencia de la intensidad lumínica y el área foliar en el porcentaje de enraizamiento de las estacas. El más alto enraizamiento se obtuvo con el tratamiento de doble sombra y un área foliar de 20 cm² (25 % de enraizamiento. Aunque los mejores resultados indican un relativo éxito en el uso de medios de enraizamiento, es una primera aproximación para propagar esta especie que necesita ser protegida.The world market of organic edulcorants is an opportunity for “panela”, a basic domestic consumption product that provides important income to rural population.

    Thirty five years ago, while in the neutron cross section group led by Robert Howerton at LLNL, the concept of reconstructing a three dimensional spatial distribution from its projections onto two dimensional planes was tackled by some of us using three now well known methods: simple back projection, Fourier projection theorem methods and iterative least squares algebraic reconstruction. The method of iterative least squares reconstruction was implemented on patient data in the early 1970s using photons from radionuclides detected by the Anger Camera. The method useful for computed tomography was modified to include the attenuation of the photons from an unknown source through an unknown attenuation distribution (a problem thought to be intractable until 1974). These methods along with a multitude of other methods developed by my small group of Ronald Huesman, Grant Gullberg, William Greenberg and Stephen Derenzo were prepared as a library with examples in FORTRAN, RECLBL. Those codes were found useful for computed tomography, geophysical problems and plasma confinement research topics in addition to their use in Nuclear Medicine. The codes were used even in the early days of magnetic resonance imaging when back projection of filtered projection data were used before the incorporation of phase encoding methods. In 1970s computed tomography of a single section of the brain required 4 minutes for single photon tomography or positron emission tomography about 30 minutes were required. Even proton and helium ion tomography were accomplished in the 1970s but with more that 2 hours of data acquisition. Thirty years later CT systems deliver 16 sections per second with 1 mm resolution and PET systems acquire 40 sections with about 4 mm resolution in 5 minutes. Computation times have reduced from 18 hours on the CDC 6600s and 7600s for gated, list mode data to less than 5 minutes in the last 30 years. Similar ratios of improvement have benefited ultrasound and magnetic resonance imaging. So what are the constant elements of imaging and what are the elements which change in the future? By the constant elements I refer to those principles which are time or history invariant (e.g., Fourier projection theorem, methods for detection of single or limited number of sources are not optimal for continuous distributions; limited angle or incomplete data are missing sources, which cannot be set to zero; back projecting data into unnatural pixels or voxels will result in erroneous reconstructions, etc.). The elements, which will change in the future include improvements in 5 attributes of an imaging modality: spatial resolution, time resolution, volume of the imaged object, signal to noise, contrast sensitivity. Signal to noise improvements include methods to reduce scatter in photon imaging as well as improvement in data transmission and processing before digitization. The one attribute of most importance in the selection of the imaging modality to solve a problem (e.g., electric source imaging vs electron density imaging) is contrast sensitivity because it is this property which distinguishes one method from another and it is this attribute, which can be amplified as is illustrated by the injection of high atomic number contrast agents or radionuclides, which target specific tissues. A new concept in imaging is the use of a pro-targeting agent such as a chemical which will seek the target of interest or be modified by the environment of interest such that when a signaling tracer or contrast agent is injected later that agent will attach only to the modified or sequestered pro-targeting agent. The intent of this presentation is to show the evolution of PET, SPECT and MRI from the perspectives of spatial resolution and contrast sensitivity. The limits of SPECT at 1 mm resolution for animal studies, of PET at 2 mm resolution for human studies and of MRI at 50 micrometers for the surface of the brain will be presented in the context of new scintillation detector materials, new imaging gantries and magnetic fields of 12 T. A presentation of an algorithm for Fresnel coded aperture imaging will initiate a discussion of other coded aperture approaches of interest to LLNL.

    Full Text Available FIABA ONLUS (Italian Fund for Elimination of Architectural Barriers was founded in 2000 with the aim of promoting a culture of equal opportunities and, above all, it has as its main goal to involve public and private institutions to create a really accessible and usable environment for everyone. Total accessibility, Total usability and Total mobility are key indicators to define quality of life within cities. A supportive environment that is free of architectural, cultural and psychological barriers allows everyone to live with ease and universality. In fact, people who access to goods and services in the urban context can use to their advantage time and space, so they can do their activities and can maintain relationships that are deemed significant for their social life. The main aim of urban accessibility is to raise the comfort of space for citizens, eliminating all barriers that discriminate people, and prevent from an equality of opportunity. “FIABA FUND - City of ... for the removal of architectural barriers” is an idea of FIABA that has already affected many regions of Italy as Lazio, Lombardy, Campania, Abruzzi and Calabria. It is a National project which provides for opening a bank account in the cities of referring, in which for the first time, all together, individuals and private and public institutions can make a donation to fund initiatives for the removal of architectural barriers within its own territory for a real and effective total accessibility. Last February the fund was launched in Rome with the aim of achieving a Capital without barriers and a Town European model of accessibility and usability. Urban mobility is a prerequisite to access to goods and services, and to organize activities related to daily life. FIABA promotes the concept of sustainable mobility for all, supported by the European Commission’s White Paper.

    The crystal structures, band structures, elastic constants, hardness, and optical properties of pyrite-type dinitrides (CN 2, SiN 2, and GeN 2) are obtained from the density functional theory using the plane-wave pseudopotential (PWP) method within the local density and generalized gradient approximations. The formation enthalpies for AN 2 (A=C, Si, and Ge) compounds suggest the three structures that are stable. The calculated band structures show the indirect gaps ( Γ-R) in CN 2, SiN 2, and GeN 2. The intrinsic hardnesses of AN 2 (A=C, Si, and Ge ) compounds are calculated. Our results show that the cubic CN 2 and SiN 2 are superhard materials. Furthermore, we studied the optical properties such as the complex dielectric function and the electron energy loss spectra.

    Full Text Available Este trabajo realiza una estadística de la frecuencia de las nevadas ocurridas sobre el sudeste de la provincia de Buenos Aires durante un período de 35 años (1960-2004. Utilizando información de tiempo presente se detectaron 32 eventos de nevada, 7 de los cuales produjeron nieve en más de una estación sinóptica. A fin de comprender los patrones de circulación, se realiza una climatología sinóptica de las incursiones de aire frío que son responsables de nevadas en la región de estudio. Dichos patrones se caracterizan por anomalías extremas en las vaguadas asociadas a frentes fríos y en las cuñas posfrontales que denotan la intensidad de dichos sistemas. El campo de anomalías de altura geopotencial muestra en los casos de nieve generalizada un mínimo sobre la vaguada frontal que duplica la intensidad de la obtenida en los casos de nieve aislada. El intenso régimen ciclónico favorece la convergencia en niveles bajos y el fuerte enfriamiento, evidente en las anomalías del campo térmico en niveles medios, indicando la inestabilidad generada en la masa de aire que es conducida hacia el norte sobre la costa patagónica y el Mar Argentino. En un caso particular de nevada generalizada, asociada a una fuerte incursión de aire frío ocurrida el 10 de julio de 2004 sobre el sudeste de la costa bonaerense, se analiza la situación sinóptica utilizando el modelo "Sistema de Modelado Atmosférico Regional" (RAMS como herramienta de diagnóstico y se la relaciona con las muestras previamente encontradas, caracterizando la masa de aire polar y su evolución. La nevada se asocia a una inestabilización sostenida de la masa de aire, favorecida por calentamiento y humedecimiento en una trayectoria dominantemente marítima y por convergencia en un régimen ciclónico en niveles bajos.This paper presents a statistic of the frequency of snow-fall occurred over the southeast of Buenos Aires province over a 35 year period (1960-2004.

    Impacts of SiN passivation on the degradation modes of AlGaN/GaN high electron mobility transistors are investigated. The gate leakage current decreases significantly upon removing the SiN layer and no clear critical voltage for the sudden degradation of the gate leakage current can be observed in the reverse-bias step-stress experiments. Gate-lag measurements reveal the decrease of the fast-state surface traps and the increase of slow-state traps after the passivation layer removal. It is postulated that consistent surface charging relieves the electric field peak on the gate edge, thus the inverse piezoelectric effect is shielded.

    Reliable determination of Rotation-Activity Correlation (RAC's) depends on precise measurements of the following stellar parameters: $T_{eff}$, parallax, radius, metallicity, and rotational speed $v\\sin i$. In this paper, our goal is to focus on the determination of these parameters for a sample of K and M dwarfs. In a future paper (Paper II), we will combine our rotational data with activity data in order to construct RAC's. Here, we report on a determination of effective temperatures based on the (R-I)$_C$ color from the calibrations of Mann et al. (2015) and Kenyon \\& Hartmann (1995) for four samples of late-K, dM2, dM3 and dM4 stars. We also determine stellar parameters ($T_{eff}$, $log(g)$ and [M/H]) using the PCA-based inversion technique for a sample of 105 late-K dwarfs. We compile all effective temperatures from the literature for this sample. We determine empirical radius-[M/H] correlations in our stellar samples. This allows us to propose new effective temperatures, stellar radii, and metallici...

  3. ¿Con o sin ancestros?: vigencia de lo ancestral en la Amazonía peruana

    Full Text Available La existencia o no de ancestros en la Amazonía indígena ha sido objeto de importantes debates. Sin embargo, los líderes de la región no dudan en llamar ‘ancestrales’ sus saberes, normas o territorios, en un sentido que, desde un punto de vista académico, puede parecer enigmático. «Ancestrales, pero… ¿con o sin ancestros?», preguntaría entonces, confuso, el antropólogo. En este artículo propongo aportar elementos de respuesta a esta pregunta a través del caso peruano. Primero analizo cómo los líderes indígenas amazónicos, conectándose al circuito del derecho internacional, adoptan la noción jurídica de ‘posesión ancestral’ del territorio para adaptarla al ámbito político. Este planteamiento rinde cuenta de la generalización y uniformización reciente del vocablo ‘ancestral’ pero deja pendiente el problema de su eventual articulación con las cosmologías indígenas que pretende reflejar. Por eso, en la segunda parte, intento sondear sobre la pertinencia de la categoría de ‘ancestro’ en la Amazonía indígena, recordando brevemente el debate académico para ir definiendo en qué medida esta categoría puede cobrar sentido. A partir del testimonio de un experimentado líder awajún, la tercera parte permite, entonces, volver más explícitos los diferentes sentidos y planos referenciales que despliega la referencia a lo ancestral, mostrando cómo los indígenas amazónicos no solo adoptan elementos conceptuales y discursivos externos, sino que al mismo tiempo los transforman a partir de sus propias singularidades cosmológicas y perspectivas políticas.

  4. La salvación sin mediaciones según Marción y la respuesta de Tertuliano

    Full Text Available Marción profesa un severo pesimismo cosmológico y antropológico, que tiene su punto de partida en la pregunta acerca del origen del mal y en una comprensión literal de algunos versículos bíblicos. Esta valoración repercute en una valoración también negativa del Creador (confirmada por la imperfección del mundo y el pecado del hombre. El Dios Verdadero, por su parte es totalmente extranjero respecto del hombre y del mundo. Este carácter extranjero, propio del Dios Supremo, impide que este se valga de las realidades creadas para revelarse. El mundo es adversario del Dios Bueno. Por lo tanto, ninguna realidad creada puede servir de mediación entre el alma del hombre y el Verdadero Dios: se plantea una salvación sin mediaciones. La última parte del artículo estudia sumariamente la reacción de Tertuliano, que insiste en una justa valoración de las realidades creadas: hay que admitir, a la vez, una cierta distancia y una cierta familiaridad entre Dios y el mundo.Marcion confesses a deep cosmological and anthropological pessimis, derived from the question about the origin of evil and form a literal understanding of the some biblical verses. Such valorisation also has repercussions on a negative valorisation of the Creator (confirmed by the imperfection of the world and the sin of man. The real God, is an entire stranger to man and the world. Such foreign character, characteristic of the Supreme God, prevents Him from revealing Himself through the created realities. The world is the good God’s adversary, so no created reality may serve as mediation between the human soul and the True God: He advocates a salvation without mediations. The final part of article presents a summary of Tertulian’s reaction, who stresses the just valorisation of the created realities: the acceptance of both a certain distance and familiarity between God and the World.

    In the ill hospitalized patient with clinically relevant malnutrition, there is a measurable decrease in the ratio of the total body potassium to total body water (TBK/TBW) and a detectable increase in the ratio of total exchangeable sodium to total exchangeable potassium (Nae/Ke). To evaluate body composition analyses in anorexia nervosa patients with chronic uncomplicated semistarvation, TBK and TBW were measured by whole body K40 counting and deuterium oxide dilution in 10 females with stable anorexia nervosa and 10 age-matched female controls. The ratio of TBK/TBW was significantly (p less than 0.05) higher in anorexia nervosa patients than controls. The close inverse correlation found in published studies between TBK/TBW and Nae/Ke together with our results suggest that in anorexia nervosa, Nae/Ke may be low or normal. A decreased TBK/TBW is not a good indicator of malnutrition in the anorexia nervosa patient. The use of a decreased TBK/TBW ratio or an elevated Nae/Ke ratio as a definition of malnutrition may result in inappropriate nutritional management in the patient with severe nonstressed chronic semistarvation.

    Full Text Available Marx’s conception of history has always been the object of multiple discussions. This is intimately linked to the reception of historical materialism, elevated to the category of dogma. In this work we try, on the contrary, to reconstruct in a systematic way Marx’s reflections on history. On the one hand, he continues to write the philosophy of history of the Enlightenment up to Hegel in accordance to the precepts of universal history, and even radicalizing the historical perspective, in so far as he considers nature and man as historical events. On the other hand, Marx criticizes the faith in progress of the Enlightenment questioning the defended parallelism between technical and economic progress, and political and moral progress. In the same way, Marx also criticizes Hegel’s idealist philosophy and liberates philosoph of history from metaphysical presuppostions.La concepción de la historia de Marx ha sido siempre objeto de intensas discusiones, lo cual está estrechamente relacionado con la recepción del materialismo histórico, elevado a la categoría de dogma. En este trabajo se intenta, por el contrario, reconstruir de forma sistemática las reflexiones de Marx sobre la historia. Por un lado, continua escribiendo la filosofía de la historia de la Ilustración hasta Hegel conforme a los preceptos de la historia universal, radicalizando incluso la perspectiva histórica, en tanto que considera a la naturaleza y al hombre sucesos históricos. Por otro, Marx critica la fe en el progreso de la Ilustración cuestionando el paralelismo defendido entre progreso técnico y económico y progreso político y moral. Del mismo modo, Marx también critica la filosofía idealista de Hegel y libera la filosofía de la historia de supuestos metafísicos.
