Recent findings In random-start protocols, the number of total and mature oocytes retrieved, oocyte maturity rate, mature oocyte yield and fertilization rates are similar to those in conventional (early follicular phase start) protocols. Starting ovarian stimulation in the late follicular or luteal phase did not show any superiority against the other. The presence of corpus luteum or luteal pha...

Abstract. This paper presents a new edge-swap heuristic for generating spanning trees with a minimum number of branch vertices, i.e. vertices of degree greater than two. This problem was introduced in Gargano et al. (2002) and has been called the minimum branch vertices (MBV) problem by Cerulli et al. (2009). The heuristic starts with a random spanning tree and iteratively reduces the number of...

LUX is a new hash function submitted to NIST’s SHA-3 competition. In this paper, we found some non-random properties of LUX due to the weakness of origin shift vector. We also give reduced blank round collision attack, free-start collision attack and free-start preimage attack on LUX-256. The two collision attacks are trivial. The freestart preimage attack has complexity of about 2 and requires...

Start-up subsidies are a frequently employed policy instrument, the use of which is justified by alleged market failure resulting from positive external effects and capital market imperfections. This article investigates whether the allocation of subsidies reflects a policy focus on addressing these market failure occurrences. However, using survey data from the East German state of Thuringia, ...

Statistical methodology is presented for the analysis of multiple events with random eeects and measurement error. We model multiple events in a general space using a random measure, and deene point process regression models with residual random eeects. Our approach to parameter estimation and signiicance testing is to start with a simple naive model of Poisson process regression, and then to a...

this study aimed at investigating the effect of blocked, incremental systematic and random contextual interferences on acquisition, retention and transfer of volleyball skills based on changes in a generalized motor program. in fact, this study was conducted to answer this question that whether regular increment of contextual interference level is more effective on learning volleyball service s...

We consider random walks that start and are absorbed on the leaves of random networks and study the length of such walks. For the networks we investigate, Erdős-Rényi random graphs and Barabási-Albert scale free networks, these walks are not transient and we consider various approaches to computing the probability of a given length walk. One approach is to label nodes according to both their to...
