Degenerate binomial and Poisson random variables associated with degenerate Lah-Bell polynomials

open access: yesOpen Mathematics, 2021
The aim of this paper is to study the Poisson random variables in relation to the Lah-Bell polynomials and the degenerate binomial and degenerate Poisson random variables in connection with the degenerate Lah-Bell polynomials. Among other things, we show

Statistical Complexity of Quantum Learning

open access: yesAdvanced Quantum Technologies, EarlyView.
The statistical performance of quantum learning is investigated as a function of the number of training data N$N$, and of the number of copies available for each quantum state in the training and testing data sets, respectively S$S$ and V$V$. Indeed, the biggest difference in quantum learning comes from the destructive nature of quantum measurements ...

On a sequence of sparse binomial-type polynomials

open access: yesJournal of Mathematical Analysis and Applications, 2013
Abstract The sequence of sparse polynomials ∑ k = 0 n ( n k ) z k ( k − 1 ) / 2 arises naturally in a graph theoretic setting. Here we study these polynomials in their own right; we derive some identities and study both algebraic and analytic properties, among them the distribution of real and complex ...

Proper Implicit Discretization of Arbitrary‐Order Robust Exact Differentiators—Without and With Noise Filtering

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper considers the implicit Euler discretization of Levant's arbitrary order robust exact differentiator (RED) and Levant and Livne's arbitrary order robust exact filtering differentiator in the presence of sampled measurements.

Living under the scope: behavior affects survival in a heavily harvested and long‐lived ungulate

open access: yesWildlife Biology, EarlyView.
The spatiotemporal behavior of game species may play a critical role in their survival throughout the hunting season. Where humans are the most dominant predators, avoidance of landscape features that allow hunter access to hunting grounds can be key to increasing survival.

Complex centers of polynomial differential equations

open access: yesElectronic Journal of Differential Equations, 2007
We present some results on the existence and nonexistence of centers for polynomial first order ordinary differential equations with complex coefficients.

Battle of the giants: Clonal expansion rates, effects on wetland plant communities and competition between introduced Phragmites australis australis and native Phragmites australis americanus

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The success of non‐native species in novel environments has received worldwide attention, resulting in dozens of hypotheses trying to explain this demographic success.

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates

open access: yesThe Economic Journal, EarlyView., 2018
The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Temperature influences pollinators' choice of floral partners independently of community composition

open access: yesJournal of Animal Ecology, EarlyView.
This paper presents novel research that empirically demonstrates a direct link between temperature and plant–pollinator interaction patterns, independently of changes to community composition in either guild. We find that even without changes to community composition, pollinators including bumblebees exhibit different interactions across temperatures ...
