Beyond deficiency:Potential benefits of increased intakesof vitamin K for bone and vascular health
No full textVitamin K is wellknown for its role in the synthesisof a number of blood coagulationfactors.During recent years vitaminK-dependent proteins werediscovered to be of vital importancefor bone and vascular health.Recommendations for dietary vitaminK intake have been made onthe basis of the hepatic requirementsfor the synthesis of bloodcoagulation factors.Accumulatingevidence suggests that the requirementsfor other functions thanblood coagulation may be higher.This paper is the result of a closedworkshop (Paris,November 2002)in which a number of Europeanvitamin K experts reviewed theavailable data and formulated theirstandpoint with respect to recommendeddietary vitamin K intakeand the use of vitamin K-containingsupplements

Zober38th International Cosmic Ray Conference (ICRC2023), Nagoya, Japan, 26 July - 3 August, 2023The CALET Calorimeter on the International Space Station(ISS) has previously measured the flux and spectrum of iron cosmic-ray nuclei above 10 GeV/n. In order to extend the measurement to the region below 10 GeV/n, we carry out an analysis to utilize the geomagnetic effect. Cutoff rigidities of cosmic-ray nuclei are calculated for all directions for each observation point in the ISS orbit. The integral spectrum of observed rigidities is then obtained by counting the number of iron nuclei in each bin of cutoff rigidity. The absolute flux and differential spectrum are then calculated by taking the detection efficiencies into account. Here we present the details of the analysis procedure and the iron spectrum below 10 GeV/n.We gratefully acknowledge JAXA’s contributions to the development of CALET and to the operations onboard the International Space Station.

On the Iwasawa -invariants of cyclotomic -extensions of real abelian fields (Algebraic Number Theory and Related Topics 2014)
No full text"Algebraic Number Theory and Related Topics 2014". December 1～5, 2014. edited by Takeshi Tsuji, Hiroki Takahashi and Yuichiro Hoshi. The papers presented in this volume of RIMS Kôkyûroku Bessatsu are in final form and refereed.Let p be a prime number and k a real abelian field. We denote by λp(k) the Iwasawa λ-invariant associated to the ideal class group of the cyclotomic Zp-extension of k. It is conjectured that λp(k) = 0. In [9], [10] and [11], Ichimura and Sumida discovered a good method for verifying that λp(k) = 0 for an odd prime number p. In this paper, we give a criterion for λ2(k) = 0, as a generalization of the preceding result [6]. Our criterion is considered as an even prime version of the theorem of Ichimura and Sumida
Characterization of the asymptotic distribution of semiparametric M-estimators
No full textThis paper develops a concrete formula for the asymptotic distribution of two-step, possibly non-smooth semiparametric M-estimators under general misspecification. Our regularity conditions are relatively straightforward to verify and also weaker than those available in the literature. The first-stage nonparametric estimation may depend on finite dimensional parameters. We characterize: (1) conditions under which the first-stage estimation of nonparametric components do not affect the asymptotic distribution, (2) conditions under which the asymptotic distribution is affected by the derivatives of the first-stage nonparametric estimator with respect to the finite-dimensional parameters, and (3) conditions under which one can allow non-smooth objective functions. Our framework is illustrated by applying it to three examples: (1) profiled estimation of a single index quantile regression model, (2) semiparametric least squares estimation under model misspecification, and (3) a smoothed matching estimator. © 2010 Elsevier B.V.

No full textAsymptotic Expansions for Some Semiparametric Program Evaluation Estimators
No full textWe investigate the performance of a class of semiparametric estimators of the treatment effect via asymptotic expansions. We derive approximations to the first two moments of the estimator that are valid to 'second order'. We use these approximations to define a method of bandwidth selection. We also propose a degrees- of-freedom like bias correction that improves the second order properties of the estimator but without requiring estimation of higher order derivatives of the unknown propensity score. We provide some numerical calibrations of the results.Bandwidth selection, kernel estimation, program evaluation, semiparametric estimation, treatment effect.
