Results from phylogenetic analysis of nuclear rDNA internal transcribed spacer (ITS) sequences from a worldwide sample of Sanicula indicate that Hawaiian sanicles (Sanicula sect. Sandwicenses) constitute a monophyletic group that descended from a western North American ancestor in Sanicula sect. Sanicoria, a paraphyletic assemblage of mostly Californian species. A monophyletic group comprising ...

Preface Designing Screening Experiments (DSE) is a class of information-theoretical models for multiple-access channels (MAC). In Sect. 2-4, we discuss the combinatorial model of DSE called a disjunct channel model. This model is the most important for applications and closely connected with the superimposed code concept. In Sect. 2, we give a detailed survey of lower and upper bounds on the ra...

Pad6 approximants are a frequently used tool for the solution of mathematical problems. One of the main drawbacks of their use for multivariate functions is the calculation of the derivatives of f ( x 1 .... ,xp). Therefore multivariate Newton-Pad6 approximants are introduced; their computation will only use the value of f at some points. In Sect. 1 we shall repeat the univariate Newton-Pad6 ap...

We describe an implementation of the Maximally Stable Extremal Region ([3], Sect. 2, MSER) feature detector and an immediate multi-dimensional generalization ([1], Sect. 2). We propose an algorithm (Sect. 3) that is essentially uniontree with path-compression and union-by-rank (see for instance [4]). However we do not use the N-tree graph of [4] as for the purpose of fitting ellipses to the MSE...

ساختار تشریحی گونه های مورد مطالعه از جنس onosma l. در ایران نشان می دهد که نوع کرک ها یکی از صفات مشخص در شناسایی گونه ها و تفکیک بخش ها در جنس onosma می باشد ساختمان درونی پهنک برگ نیز دو گروه را بخوبی مشخص می سازد، در بخش های sect. podonosma و sect. protonosma دارای مزوفیل یک طرفه (پارانشیم نرده ای فقط زیر اپیدرم فوقانی) است ولی در بخش sect. onosma مزوفیل برگ به صورت دو طرفه با لایه های پارا...

The system AProVE (Automated Program Verification Environment) can be used for automated termination and innermost termination proofs of (conditional) term rewrite systems (TRSs). AProVE currently offers the techniques of recursive path orders possibly with status [3] (Sect. 2), dependency pairs including recent refinements such as narrowing, rewriting, and instantiation of dependency pairs [1,...

The paper attempts to rationalize cooperation in the one-shot prisoners’ dilemma (PD). It starts by introducing (and preliminarily investigating) a new kind of equilibrium (differing from Aumann’s correlated equilibria) according to which the players’ actions may be correlated (sect. 2). In PD the Pareto-optimal among these equilibria is joint cooperation. Since these equilibria seem to contrad...

دو گونه Acantholimon bakhtiaricum و A. mirtadzadinii از ایران نامگذاری و معرفی می‌گردند. گونه A. bakhtiaricum  متعلق به بخش sect. Microstegia و گونه A. mirtadzadinii متعلق به بخش sect. Acantholimon  است. گونه A. bakhtiaricum با گونه A. austro-iranicum قرابت زیادی دارد، لیکن در پوشش کرکی و شکل و اندازه برگک با آن تفاوت فاحشی دارد. گونه A. mirtadzadinii با گونه A. demavendicum  شبیه است. تفاوت عم...

The name Carex poeppigii (sect. Echinochlaenae) is validated and a new combination in South American Carex, C. vixdentata (sect. Spirostachyae), is made here. Also, the taxonomic status of C. aueri is discussed, and this name is placed in the synonymy of C. reichei (sect. Arenariae).
