How many shots are enough? Optimizing precision measurements when testing lead‐free ammunition
Wildlife Biology, EarlyView.Growing concern about lead exposure in scavenging wildlife and the consumers of game meat has increased interest in evaluating the performance of lead‐free rifle ammunition. Testing both accuracy and precision helps ensure reliable shot placement while reducing the risk of non‐fatal woundings.

Coefficient determination via asymptotic spreading speeds [PDF]
Inverse Problems, 2014 In this paper, we analyze the inverse problem of determining the reaction term f (x, u) in reaction-diffusion equations of the form ∂tu − D∂xxu = f (x, u), where f is assumed to be periodic with respect to x ∈ R. Starting from a family of exponentially decaying initial conditions u0,λ, we show that the solutions uλ of this equation propagate with ...

Spread of branching diffusion: Sharp asymptotics
Stochastics and Stochastic Reports, 2004A one-dimensional branching diffusion with a stable drift is considered. Let Rt denote the position of the rightmost particle at time t. It is shown that Rt , properly normalized, has a limiting distribution.

An Asymptotic Model for the Spreading of a Collimated Beam
Nuclear Science and Engineering, 1992In this paper, the authors show, using asymptotics, that under conditions when the angular distribution is forward peaked, the transport equation can be reduced to an advection-diffusion equation for the scalar flux. This equation describes lateral diffusive spreading with depth of an initially collimated beam of arbitrary spatial cross section and is ...

The asymptotic spread of estimators
Journal of Statistical Planning and Inference, 1989The spread and asymptotic spread of estimators are discussed. Inequalities on local and global asymptotic spread of estimators are derived under certain regularity conditions.

On the progressive spread over strategic diffusion: Asymptotic and computation
2015 IEEE Conference on Computer Communications (INFOCOM), 2015We study how an innovation (e.g., product or technology) diffuses over a social network when individuals strategically make selfish, rational choices in adopting the new innovation. This diffusion has been studied by modeling individuals' interactions with a noisy best response dynamic over a networked coordination game, but mainly in the ...

Asymptotic Behavior, Spreading Speeds, and Traveling Waves of Nonmonotone Dynamical Systems
SIAM Journal on Mathematical Analysis, 2015Let \(C=BC(\mathbb{R}^N,\mathbb{R})\) and \(C_+=BC(\mathbb{R}^N,\mathbb{R}_+)\), which is of the norm \(\|\phi\|_C\) deduced by the so-called compact open topology. Consider the iteration system \(u_{n+1}(x)=Q[u_n](x)\), \(u_0=\phi\), where \(Q:C_+\to C_+\) is continuous and compact. In [ibid. 13, 353--396 (1982; Zbl 0529.92010)], \textit{H.
