Observations on the Relationship between Crash Frequency and Traffic Flow
Safety, 2021 This work analyzes the relationship between crash frequency N (crashes per hour) and exposure Q (cars per hour) on the macroscopic level of a whole city. As exposure, the traffic flow is used here.

The Journal of Wildlife Management, EarlyView.We present an approach for estimating wildlife abundance from unstructured aerial surveys. We combine a spatial model for count data with auxiliary information on detection probability. This framework is intended to be flexible, requiring lower survey costs and less computation time than other alternatives for estimating abundance.

Climate warming disrupts zooplankton phenology and overwintering strategies
Limnology and Oceanography, EarlyView.Abstract Zooplankton are crucial for food webs and biogeochemical cycles. However, warming associated with climate change may alter their seasonal timing and reproductive strategies. This study investigated how long‐term warming impacted zooplankton (mainly copepods) phenology and overwintering strategies by comparing a Baltic Sea bay, heated by warm ...

Asymptotic Properties for a General Class of Szász–Mirakjan–Durrmeyer Operators
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this paper, we introduce a general family of Szász–Mirakjan–Durrmeyer type operators depending on an integer parameter j∈ℤ$$ j\in \mathbb{Z} $$. They can be viewed as a generalization of the Szász–Mirakjan–Durrmeyer operators, Phillips operators, and corresponding Kantorovich modifications of higher order.

Pascal type properties of Betti numbers
International Journal of Mathematics and Mathematical Sciences, 1994 In this paper, we will describe the Pascal Type properties of Betti numbers of ideals associated to n-gons. These are quite similar to the properties enjoyed by the Pascal's Triangle, concerning the binomial coefficients. By definition, the Betti numbers

Some Algebraic Aspects of Morse Code Sequences [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 Morse code sequences are very useful to give combinatorial interpretations of various properties of Fibonacci numbers. In this note we study some algebraic and combinatorial aspects of Morse code sequences and obtain several q-analogues of Fibonacci ...

Umbral calculus, binomial enumeration and chromatic polynomials [PDF]
Transactions of the American Mathematical Society, 1988 We develop the concept of partition categories, in order to extend the Mullin-Rota theory of binomial enumeration, and simultaneously to provide a natural setting for recent applications of the Roman-Rota umbral calculus to computations in algebraic topology. As a further application, we describe a generalisation of the chromatic polynomial of a graph.
