A simple inverse model is proposed to deduce hemisphere-integrated COS flux based on published time series of total column COS. The global atmosphere is divided into two boxes representing the Northern and Southern Hemispheres, and the total column COS data from several stations are used to calculate hemispheric COS loadings. The integrated flux within each hemisphere is calculated as a linear ...

In this paper, we propose a new generalization of the Poisson distribution by using concept weighted distribution; trigonometric weight with cosine function is used. We derive some distributional properties distribution, such as cumulative function, moment generating factorial moments, and index dispersion. Then, related model considered for modeling purposes, estimation parameters performed vi...

Background: To determine whether random-start controlled ovarian stimulation (COS), in which a stimulation is performed regardless to day of patient’s menstrual cycle, has similar outcomes in comparison to conventional early follicular phase-start COS for cryopreservation of fertilized oocytes in cancer patients. Materials and Methods: This prospective study was performed at two infertility cen...

We propose an integrable extension of nonlinear sigma model on the target space of Hermitian symmetric space (HSS). Starting from a discussion of soliton solutions of O(3) model and an integrally extended version of it, we construct general theory defined on arbitrary HSS by using the coadjoint orbit method. It is based on the exploitation of a covariantized canonical structure on HSS. This ter...

In transportation applications such as real-time route guidance, ramp metering, congestion pricing and special events traffic management, accurate short-term flow prediction is needed. For this purpose, paper proposes several novel online Grey system models (GM): GM(1,1|cos(?t)), GM(1,1|sin(?t),cos(?t)), GM(1,1|e-at,sin(?t),cos(?t)). To evaluate the performance of proposed models, they are comp...

Foetal loss and intrauterine growth restriction are major problems in mammals, but there are few effective ways in preventing it. Intriguingly, chitosan oligosaccharide (COS), a biomaterial derived from chitosan, can promote foetal survival and growth. Therefore, we have investigated how COS affects foetal survival and growth in a pig model. Fifty-two sows were divided into two treatment groups...

3a An instructive toy model: two paradoxes We start with a very simple random trigonometric polynomial (even simpler than 1c12): (3a1) X(t) = ζ cos t+ η sin t where ζ, η are independent N(0, 1) random variables. Its distribution is the image of γ under the map (x, y) 7→ (t 7→ x cos t+ y sin t). Time shifts of the trigonometric polynomial correspond to rotations of R, (3a2) X(t− α) = ζ(cos t cos...

Carbonyl sulfide (COS) is one of the major sources of stratospheric sulfate aerosols, which affect the global radiation balance and ozone depletion. COS-degrading microorganisms are ubiquitous in soil and important for the global flux of COS. We examined the sulfur isotopic fractionation during the enzymatic degradation of COS by carbonyl sulfide hydrolase (COSase) from Thiobacillus thioparus T...
