Abstract Premise In North America, Phragmites australis (common reed) has drawn a great deal of research attention. Non‐native P. australis subsp. australis is a noxious weed that has locally displaced native P. australis subsp. americanus in some areas.

Portfolio optimization by applying Markov chains [PDF]
Since one of the main problems in today's economy is 'conquering the market' or, in other words, finding the best way to predict price movements and receive expected rates of return, this paper will deal with the portfolio optimization in the Belgrade ...

Products of stochastic matrices and applications
This paper deals with aspects of the limit behaviour of products of nonidentical finite or countable stochastic matrices (Pn). Applications are given to nonhomogeneous Markov models as positive chains, some classes of finite chains considered by Doeblin ...

Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

First passage of a Markov additive process and generalized Jordan chains [PDF]
In this paper we consider the first passage process of a spectrally negative Markov additive process (MAP). The law of this process is uniquely characterized by a certain matrix function, which plays a crucial role in fluctuation theory.

Early evolution of the gular musculature and its innervation in ray‐finned fishes
Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

Mixing Times of Markov Chains: from Coupling to Paths [PDF]
openA well-known result in the theory of Markov chains, the Convergence Theorem, states that if we assume the chain to be aperiodic and irreducible, then its distribution converges to equilibrium.

Markov Chains, Random Walks, and Card Shuffling
A common question in the study of random processes pertains to card shuffling. Whether or not a deck of cards is random can have huge implications on any game being played with those particular cards.

Evolutionary morphology of the haplorhine hamate
Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.
