Orchids

aperture in the tissues surrounding the meristems. 'This simple experiment revealed that there were four distinct regions of the embryo with different plasmodesmata apertures. The shoot meristem had the highest aperture enabling movement of single-to-triple sized GFP; the hypocotyl (embryonic stem) allowed single, double and some triple-sized GFP movement; the root allowed single and double-siz...

The Orchids Intrusion Detection Tool

ORCHIDS is an intrusion detection tool based on techniques for fast, on-line model-checking. Temporal formulae are taken from a temporal logic tailored to the description of intrusion signatures. They are checked against merged network and system event flows, which together form a linear Kripke structure.

A Smell of Orchids

ORCHIDS is an intrusion detection tool based on techniques for fast, on-line model-checking. ORCHIDS detects complex, correlated strands of events with very low overhead in practice, although its detection algorithm has worstcase exponential time complexity. The purpose of this paper is twofold. First, we explain the salient features of the basic model-checking algorithm in an intuitive way, as...

Cyanidin 3-Oxalylglucoside in Orchids

In the last few years increasing evidence has been presented that acylated flavonoids are widespread in higher plants [1—3], Besides the well known phenolic acids (hydroxybenzoates, hydroxycinnamates), aliphatic acids have only recently been extensively detected as acyl moieties of anthocyanins or gly­ cosides of (iso)flavones and flavonols. To date, ace­ tic, butyric, malonic, 2-methylbutyric,...
