In Analytic SSA, an approximate upper bound to the logdet term in Eq. 4 is computed (Hara et al., 2012). Without re-deriving this bound entirely, we present its final steps, which we use to obtain the bounds for KSSA and NLSSA.

background: in order to deliver the precise dose to the target in radiotherapy, absorbed dose to water at the reference point should be assessed. when the calibration procedure is performed for a reference dosimeter in the 60co beam of a secondary standard dosimetry laboratory (ssdl), the total uncertainty in absorbed dose to water (dw) is estimated to be approximately 1.5%. this study attempts...

and is the tangent of F at x. Dually then, r and 1/k being the absolute points, the conic F the Feuerbach circle, and the conic R a rectangular hyperbola on the four given orthocentric points, and having its centre c on F, if the common diameter of F and R meet R at points dd', then these points are double foci of circular curves of class 3 on the 6 lines; the circles with centres d and d' and ...

Background Multicontrast CMR is the conventional method for invivo characterization of carotid plaques. However, its non-quantitative nature and the need for extensive postacquisition interpretation limit its clinical application. We have recently proposed using in-vivo quantitative T2 mapping for atherosclerotic plaque characterization [Biasiolli et al. JCMR 2013, 15:69]. T2 maps have the adva...

The asymmetric unit of the title compound, C14H25NO3, contains two independent mol-ecules with similar geometry. The morpholine and cyclo-hexane rings of both mol-ecules adopt a chair conformation. Intra-molecular O-H⋯N hydrogen bonds are observed. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds into chains parallel to the [101] direction. The chains are further connected through ...

In this paper we prove the stability of the zero equilibria of two systems of difference equations of exponential type, which are some extensions of an one-dimensional biological model. The stability of these systems is investigated in the special case when one of the eigenvalues is equal to -1 and the other eigenvalue has absolute value less than 1, using centre manifold theory. In addition, w...

The title compound, also known as cis-zearalenone (cis-ZEN), C(18)H(22)O(5), has already been reported elsewhere [Griffin et al. (1981 ▶). ACA Ser.29, 35], but no atomic coordinates are publicly available. The mol-ecule is of inter-est with respect to its toxicity. In the crystal, intra-molecular O-H⋯O hydrogen bonds stabilize the mol-ecular conformation, while inter-molecular O-H⋯O hydrogen bo...

The lateral migration of a neutrally buoyant rigid sphere suspended in a secondorder fluid is studied theoretically for unidirectional two-dimensional flows. The results demonstrate the existence of migration induced by normal stresses whenever there is a lateral variation of the shear rate in the undisturbed flow. The migration occurs in the direction of decreasing absolute shear rate, which i...

We present accurate measurements of the central wavelengths of 4947 atomic absorption lines in the solar optical spectrum. The wavelengths, precise to a level ∼ 50 − 150 m s −1 , are given for both flux and disc-centre spectra, as measured in relatively recent FTS solar atlases. This catalogue modernizes existing sources based on photographic measurements and provides a benchmark to test and pe...
