Review of Data Collection Methods for Microscopic Traffic Simulation
No full textResearch into developing more reliable microscopic traffic simulation models is seriously hampered by the availability of suitable microscopic data for calibration and validation purposes. This paper presents a review of several data collection technologies that the authors have been experimenting with. The methods include (i) video recording (ii) the use of differential GPS (DGPS) and (iii) an instrumented vehicle fitted with the S.M.S. Drive Recorder system. Examples of data collection with each method are briefly described, and some of the results presented to illustrate the capabilities of the methods. The last section of the paper summarises the advantages and limitations of each method and conclusions are drawn on their suitability for the required purpose. The experiments shows that each method can provide some useful results for microscopic simulation model development, but cannot provide continuous spacing-, speed- and acceleration profiles of large vehicle platoons moving through various traffic scenarios. Further research is required to develop more sophisticated data collection techniques and to investigate such aspects of driver behaviour as aggressiveness, and factors influencing lane selection
D-vitamiinilisän käyttö imeväisikäisillä
No full textTämä tutkielma käsittelee D-vitamiinia ja imeväisikäisten D-vitamiinilisäravinteen käyttöä. D-vitamiini on tärkeä elimistölle jo imeväisiästä alkaen. D-vitamiini vaikuttaa elimistön kalsiumin ja fosforin aineenvaihduntaan sekä ehkäisee lasten riisitautia ja aikuisten osteomalasiaa. Se edesauttaa muun muassa normaalia kasvua, luuston terveyttä ja hyvinvointia sekä immuunijärjestelmän normaalia toimintaa. D-vitamiinin puutos on yhdistetty myös imeväisikäisillä useiden sairauksien kuten hengitystieinfektioiden, vakavan varhaislapsuuden hammaskarieksen sekä allergisten sairauksien riskiin.
D-vitamiinilisän käyttösuosituksissa tulee ottaa huomioon sekä puutoksen että liikasaannin ehkäiseminen. Suomessa imeväisikäisille suositellaan D-vitamiinilisää käytettäväksi kahden viikon iästä alkaen, koska imeväisikäiset ovat erityisen alttiita D-vitamiinin puutokselle vähäisen auringonvaloaltistuksen sekä äidinmaidon alhaisen D-vitamiinipitoisuuden takia. Tällä hetkellä D-vitamiinilisä suositellaan annosteltavaksi imeväisikäisille D-vitamiinitipoilla. D-vitamiinin rasvaliukoisuuden takia sen haittapuolena on hidas liukeneminen ja huono imeytyminen suun kautta annosteltaessa, ja nämä vaikuttavat D-vitamiinilisäannoksen biologiseen hyötyosuuteen.
D-vitamiinilisää ei voi kuitenkaan antaa ylimäärin, sillä D-vitamiinin liikasaanti johtaa toksisiin vaikutuksiin. D-vitamiinin biologista hyötyosuutta voitaisiin parantaa esimerkiksi lääkeaineen annostelujärjestelmien avulla. Erityisen lupaavalta menetelmältä vaikuttaa itsestään mikroemulgoituva lääkeaineen annostelujärjestelmä yhdistettynä nopeasti liukeneviin kalvoihin, mikä parantaa D-vitamiinin biologista hyötyosuutta. Lisäksi imeväisikäisten kohdalla tippojen annosteluprosessi tuottaa usein haasteita, ja kalvoteknologian hyödyntäminen tekisi D-vitamiinin annostelusta imeväisikäisille helpompaa ja turvallisempaa. Suurin osa lääkeaineen annostelujärjestelmistä D-vitamiinilisän kuljettajina ovat vielä alkututkimusvaiheessa, ja etenkin niiden mahdollinen soveltaminen imeväisikäisille vaatii lisää kehitystyötä sekä käytännön tutkimustietoa

Measurement of mass and width of the excited charmed meson states D-1(0) and D-2(*0) at CDF
No full textWe report on precision measurements of the masses and widths of the narrow, orbitally excited states D-1(0) and D-2(*0) using the CDF II detector at the Fermilab Tevatron. Both states (collectively called D-**) are reconstructed in the decay channel D-**-> D*+pi(-). The D-2(*0) is also reconstructed in the D-**-> D+pi(-) channel. Using a data set with an integrated luminosity of 210 pb(-1), the measured masses and widths for the D-1(0) are 2421.7 +/- 0.7 +/- 0.6 MeV/c(2) and 20.0 +/- 1.7 +/- 1.3 MeV/c(2) respectively, while for the D-2(*0) they are 2463.3 +/- 0.6 +/- 0.8 MeV/c(2) and 49.2 +/- 2.3 +/- 1.2 MeV/c(2). These values are currently the single best measurements available
Value of housework time and changes in traditional economic well-being in Finland in 1979-2000
No full textThe paper looks at the change, the level and the structure of income distribution and distribution of consumption possibilities at the individual and at the household level between the years 1979 and 2000. I also pay attention to the development of low incomes when the concept of income is expanded to include a monetary measurement of household production. The paper uses Time Use Data, collected by Statistics Finland in 1979, 1987-1988 and 1999-2000. I find that consumption possibilities are more equally distributed than money income. Household production increases the consumption possibilities of all income groups but its effect is most significant in the low income decile groups. As a share of consumption possibilities, household production forms a significantly more important part for low income households than for high income households. By looking at consumption possibilities we can see a different distribution of economic well-being compared to distribution offered by money income measurement alone.Value of housework time, consumption possibilities, economic well-being, inequality, poverty

High frequency of bladder cancer after nephroureterectomy: justification for adjuvant intravesical treatment?
No full textMatan Mekayten, Vladimir Yutkin, Mordechai Duvdevani, Dov Pode, Guy Hidas, Ezekiel H Landau, Fadi Youssef, Ofer N Gofrit Department of Urology, Hadassah Hebrew University Medical Center, Jerusalem, Israel Background: Bladder recurrence after nephroureterectomy (NU) is common. However, there is no acceptable policy of adjuvant intravesical treatment after NU. Objective: To assess the rate of bladder recurrence following NU and to identify the high-risk subgroups that may become candidates for adjuvant intravesical therapy after NU. Patients and methods: Ninety-one patients (mean age 66.4 years) underwent NU. High-grade (HG) tumors were found in 63 patients and low-grade (LG) tumors in 28. Median follow-up was 72 months. The risk of bladder recurrence was assessed by uni- and multivariate analyses of patient and tumor characteristics. Results: Bladder recurrence developed in 38 patients (41.8%) after a median period of 11 months. Among these, 25 patients with HG upper tract urothelial carcinoma (39.7%) and 13 patients with LG upper tract urothelial carcinoma (46.4%) developed recurrence. HG bladder recurrence developed in 24 patients (63.2%) and LG recurrence developed in 14 patients (36.8%). Stages pTa, pT1, pT2, or higher bladder recurrence developed in 26 (68.4%), 7 (18.4%), and 4 patients (10.5%), respectively, and pure pTis developed in 1 patient. On uni- and multivariate analyses, the risk of bladder recurrence was independent of any clinicopathologic characteristics. Conclusion: High rate and short time interval of bladder recurrence after NU were found, with no specific subgroup of patients with increased risk. These findings support prescribing adjuvant intravesical therapy to all patients after NU. Keywords: urothelial upper tract tumors, bladder recurrence, nephroureterectom
Measurement of CP-violating asymmetries in D[superscript 0]→π[superscript +]π[superscript -] and D[superscript 0]→K[superscript +]K [superscript -] decays at CDF
No full textWe report on a measurement of CP-violating asymmetries (ACP) in the Cabibbo-suppressed D[superscript 0]→π[superscript +]π[superscript -] and D[superscript 0]→K[superscript +]K [superscript -] decays reconstructed in a data sample corresponding to 5.9 fb[superscript -1] of integrated luminosity collected by the upgraded Collider Detector at Fermilab. We use the strong decay D[superscript *+]→D[superscript 0]π[superscript +] to identify the flavor of the charmed meson at production and exploit CP-conserving strong cc̅ pair production in pp̅ collisions. High-statistics samples of Cabibbo-favored D[superscript 0]→K[superscript -]π[superscript +] decays with and without a D[superscript *±] tag are used to correct for instrumental effects and significantly reduce systematic uncertainties. We measure ACP(D[superscript 0]→π[superscript +]π[superscript -])=(+0.22±0.24(stat)±0.11(syst))% and A[subscript CP](D[superscript 0]→K[superscript +]K [superscript -] )=(-0.24±0.22(stat)±0.09(syst))%, in agreement with CP conservation. These are the most precise determinations from a single experiment to date. Under the assumption of negligible direct CP violation in D[superscript 0]→π[superscript +]π[superscript -] and D[superscript 0]→K[superscript +]K [superscript -] decays, the results provide an upper limit to the CP-violating asymmetry in D[superscript 0] mixing, |A[subscript CP][superscript ind](D[superscript 0])|<0.13% at the 90% confidence level
Measurements of branching fraction ratios and CP-asymmetries in suppressed B- -> D(-> K+ pi(-))K- and B- -> D(-> K+ pi(-))pi(-) decays
No full textWe report the first reconstruction in hadron collisions of the suppressed decays B- -> D(-> K+ pi(-))K- and B- -> D(-> K+ pi(-))pi(-), sensitive to the Cabibbo-Kobayashi-Maskawa phase gamma, using data from 7 fb(-1) of integrated luminosity collected by the CDF II detector at the Tevatron collider. We reconstruct a signal for the B- -> D(-> K+ pi(-))K- suppressed mode with a significance of 3.2 standard deviations, and measure the ratios of the suppressed to favored branching fractions R(K) = [22.0 +/- 8.6(stat) +/- 2.6(syst)] x 10(-3), R+ (K) = [42.6 +/- 13.7(stat)] +/- 2.8(syst)] x 10(-3), R- (K) = [3.8 +/- 10.3(stat) +/- 2.7(syst)] x 10(-3) as well as the direct CP-violating asymmetry A(K) = -0.82 +/- 0,44(stat) +/- 0.09(syst) of this mode. Corresponding quantities for B- -> D(-> K+ pi(-))pi(-) decay are also reported
