• Haspelmath (1993) argues that the direction of morphological derivation correlates with the likelihood that the event can occur spontaneously—events more likely to occur spontaneously are lexicalized in their morphologically basic form as words denoting non-causative COS predicates (e.g. melt), while those less likely to occur spontaneously are lexicalized in their morphologically basic form ...

für die resultierende mittlere Geschwindigkeit eines Teilchens nach einem Stoß: t>red = v c p . Aus den Gesetzen des elastischen Stoßes für Kugeln der Massen m0, mx ergibt sich für die Geschwindigkeit von 77i0 nach dem Stoß mit ß = ( (m x m0 ) / (m, + m 0 ) ) 2, e=(l/ß-l) (d/R0)2 : v=v0(ßey*(( 1 + 1/fi) — cos2 ft)1'*; (A.6) cos #m i n = (1 (R0/d)2 (ß (vmJv 0)2)/ (ß-1) cos # m a x = (1 (R0/d)2)1...

Abstract The atmospheric muon flux is generated with CORSIKA 6.030 (using QGSJET high-energy interaction model) and fitted with the formula from Gaisser (1990). Spectra and mass distribution of primaries were taken according to the poli-gonato model of Hörandel (2003). A convenient parameterization of the cos(θ) → cos(θ∗) correction, originally tabulated in Volkova (1969), is presented. This co...

t=1 exp (k1 cos(θt − θt−1) + k2 cos(θt − θt−2)) , (2) p(yt|at, θt) = Norm(yt; at cos(θt + ω̄t), σ 2 y). (3) The joint distribution over the amplitudes is a multivariate truncated Gaussian. Therefore, when the von Mises process becomes an independent, uniform distribution (k1 = 0 and k2 = 0), the model reduces to that of Sell and Slaney with a particular spectral weighting function determined by ...

BACKGROUND Chitosan oligosaccharide (COS) is widely consumed as a functional food due to its multiple health effects, but few studies about COS supplement on placental antioxidant and nutrition transport capacity were reported. Taken pregnant sow as a model, we aimed to investigate the effects of dietary COS supplementation during late gestation on placental amino acids transport and antioxidan...

In order to explore the feasibility of rapid non-destructive detection cotton leaf chlorophyll content during growth stage, this study utilized hyperspectral technology combined with a feature variable selection method conduct quantitative research. Through correlation spectroscopy (COS), total 882 representative samples from seedling bud and flowering boll stage were used for wavelength screen...

While much has been learned about black holes by analyzing the latest LVK catalog, GWTC-3, a measurement of astrophysical distribution hole spin orientations remains elusive. This is usually probed measuring cosine tilt angle ($\cos\tau$) between each and orbital angular momentum, $\cos\tau=+1$ being perfect alignment. Abbott et al. modeled $\cos\tau$ as mixture an isotropic component Gaussian ...

BACKGROUND Diffusion tensor imaging is a neuroimaging method that quantifies white matter (WM) integrity and brain connectivity based on the diffusion of water in the brain. White matter has been hypothesized to be of great importance in the development of schizophrenia as part of the dysconnectivity model. Childhood-onset schizophrenia (COS), is a rare, severe form of the illness that resemble...

The aim of the present study was to evaluate the anticancer effects of chitooligosaccharides (COS) and N-acetyl-D-glucosamine (NAG), as well as to investigate the possible mechanisms involved. MTT assay and flow cytometry were used to evaluate the effect of various concentrations of COS and NAG on the proliferation and differentiation of peripheral blood mononuclear cells (PBMCs). In addition, ...

Measurements of atmospheric carbon dioxide (CO2) have led to an understanding of the past and present CO2 trends at global scales. However, many of the processes that underlie the CO2 fluxes are highly uncertain, especially at smaller spatial scales in the terrestrial biosphere. Our abilities to forecast climate change and manage the carbon cycle are reliant on an understanding of these underly...
