The analysis of microsporogenesis in endogamous plants of popcorn (S5 to S7) showed several and distinct interchanges which involve the nucleolus organizer (chromosome 6). The detection of cells with interchanges was facilitated by the presence of two nucleoli of different sizes in contrast to normal ones with a single big nucleolus. Interchange points do not always seem to be at the same place...

Let G be a Class 1 graph with maximum degree 4 and let t ≥ 5 be an integer. We show that any proper t-edge coloring of G can be transformed to any proper 4-edge coloring of G using only transformations on 2-colored subgraphs (so-called interchanges). This settles the smallest previously unsolved case of a well-known problem of Vizing on interchanges, posed in 1965. Using our result we give an a...

The rapid advancement of urban transportation in modern China has driven economic developments. However, the progressively congested traffic conditions have affected productivity and daily life people. To mitigate congestion problem, necessary road designs should be implemented along highways, for example highway interchanges. application interchanges past cases proven to effectively avoid flow...

OBJECTIVE Driving the wrong way on freeways, namely wrong-way driving (WWD), has been found to be a major concern for more than 6 decades. The purpose of this study was to identify characteristics of this type of crash as well as to rank the locations/interchanges according to their vulnerability to WWD entries. METHODS The WWD crash data on Illinois freeways were statistically analyzed for a...

Ein weltweiter Containertransport durchläuft im Rahmen der gesamten Transportkette typischerweise eineVielzahl vonVerantwortungsbereichen. Bei den Interchanges (Übergabe von Conatiner und Verantwortlichkeit) werden lediglich Containerverlust und deutliche Außenschäden entdeckt. Häufig kommt dieWare zerstört beim Empfänger an, obwohl der Container unversehrt ist und alle Interchanges ohne Beanst...

This work proposes innovative permutation-based procedures controlling the Familywise Error rate (FWE). It is proofed that weighted procedures control the FWE if weights are a function of the sufficient statistic. Particularly, we focus on the use of the additional information given by the total variance of each variables. The first proposal considers the use of weights applied to the combining...

We propose the B c → B * u γ decay as the most suitable probe for the flavour changing neutral transition c → uγ. We estimate the short and long distance contributions to this decay within the standard model and we find them to be comparable; this is in contrast to radia-tive decays of D mesons, that are completely dominated by the long distance contributions. Since the c → uγ transition is ver...

This paper addresses the following general scenario: A scientist wishes to perform a battery of experiments, each generating a sequential stream of data, to investigate some phenomenon. The scientist would like to control the overall error rate in order to draw statistically-valid conclusions from each experiment, while being as efficient as possible. The between-stream data may differ in distr...
