Abstract Study question To investigate the influence of paternal age on live birth rates in oocyte recipient cycles Summary answer Increased appears to have a negative impact when adjusted for sperm quality. What is known already While effect maternal ART outcomes well established, unclear. Even systematic reviews assessing yielded conflicting results. Morris et al., 2020 could not demonstrate ...

Vacuum.-By creating a vacuum the process of decalcification can be characterized as follows: Insoluble calciurn-salts+acid o-soluble calciumsalts+CO2. The carbon dioxide, rapidly extracted, will disturb the balance of the chemical equilibrium, and, according to Le Chatelier, result in an acceleration of the reaction. Waerhaug (1949), however, points out that there will be a more intensive conta...

TheMinkowski sum of two setsA,B ∈ IR, denotedA⊕B, is defined as {a+ b | a ∈ A, b ∈ B}. We describe an efficient and robust implementation for the construction of Minkowski sums of polygons in IR using the convolution of the polygon boundaries. This method allows for faster computation of the sum of non-convex polygons in comparison to the widely-used methods for Minkowski-sum computation that d...

This paper presents a new algorithm for computing the hit point and normal of a ray and a general convex object. The algorithm is loosely based on the the Gilbert-Johnson-Keerthi algorithm for computing the distance between convex objects in the sense that it is applicable to the same family of convex objects and uses the same subalgorithm for computing the closest point of a simplex. Since thi...

Asexual reproduction is one of the most important traits in the evolutionary history of corals. No real-time observations of asexual reproduction in azooxanthellate solitary scleractinian corals have been conducted to date. Here, we describe previously unknown aspects of asexual reproduction by using Truncatoflabellum spheniscus (Family Flabellidae) based on observations of transverse division ...
