Endopolyploidy in Vanda Miss Joaquim (Orchidaceae)

Parentage determination of Vanda Miss Joaquim (Orchidaceae) through two chloroplast genes rbcL and matK

BACKGROUND AND AIMS The popular hybrid orchid Vanda Miss Joaquim was made Singapore's national flower in 1981. It was originally described in the Gardeners' Chronicle in 1893, as a cross between Vanda hookeriana and Vanda teres. However, no record had been kept as to which parent contributed the pollen. This study was conducted using DNA barcoding techniques to determine the pod parent of V. Mi...

A New Molecular Phylogeny and a New Genus, Pendulorchis, of the Aerides–Vanda Alliance (Orchidaceae: Epidendroideae)

BACKGROUND The Aerides-Vanda alliance is a complex group in the subtribe Aeridinae (subfamily Epidendroideae, Orchidaceae). Some phylogenetic systems of this alliance have been previously proposed based on molecular and morphological analyses. However, several taxonomic problems within this alliance as well as between it and its allies remain unsolved. METHODOLOGY/PRINCIPAL FINDINGS We utiliz...

We study a generalization of the classical Marcinkiewicz-Zygmund inequalities. We relate this problem to the sampling sequences in the Paley-Wiener space and by using this analogy we give sharp necessary and sufficient computable conditions for a family of points to satisfy the Marcinkiewicz-Zygmund inequalities.

“Reflections on Gains and Losses: A 2×2×7 Experiment” by Antoni Bosch-Domènech and Joaquim Silvestre Universitat Pompeu Fabra and University of California, Davis. What determines risk attraction or aversion? We experimentally examine three factors: the gain-loss dichotomy, the probabilities (0.2 vs. 0.8), and the money at risk (7 amounts). We find that, for both gains and losses and for low and...
