Bistable Networks Enable Complex Shape Changes
Advanced Science, EarlyView.Transition‐controlled metamaterials are networks of bistable mechanical memory that store local binary states and express them as global shape change. By decoupling low‐force programming from high‐force holding, a single lattice is reconfigured into distinct 2D profiles and 3D surfaces without continuous actuation, enabling reusable morphing materials ...

Poisson Mixed-Effects Count Regression Model Based on Double SCAD Penalty and Its Simulation Study
AxiomsThis paper focuses on variable selection and parameter estimation for mixed-effects Poisson count regression models. To simultaneously select important variables in both fixed effects and random effects, we propose a double-penalized Poisson count ...

A New Extension of the Generalized Half Logistic Distribution with Applications to Real Data
Entropy, 2019 In this paper, we introduced a new three-parameter probability model called Poisson generalized half logistic (PoiGHL). The new model possesses an increasing, decreasing, unimodal and bathtub failure rates depending on the parameters. The relationship of

Binomial Approximation to a Poisson Random Variable
, 2016 If a coin that comes up heads with probability p is tossed n times, the number of heads observed follows a binomial probability distribution. The Poisson probability distribution can be regarded as a limiting case of the binomial distribution as the ...

Learning Work Function via Implicit Reasoning on Electrostatic Potential Landscapes
Advanced Science, EarlyView.StructPot‐CLR establishes a cross‐modal contrastive learning framework that aligns the crystal structures of 2D materials with plane‐averaged electrostatic potential landscapes for physically informed work‐function prediction. The model achieves an MAE of 0.265 eV and an R2 of 0.902 on the held‐out test set while accurately preserving key morphological

Modeling and Performance of Bonus-Malus Systems: Stationarity versus Age-Correction
Risks, 2014 In a bonus-malus system in car insurance, the bonus class of a customer is updated from one year to the next as a function of the current class and the number of claims in the year (assumed Poisson).

Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore
Advanced Science, EarlyView.The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...

Poisson approximation for random sums of independent binomial random variables
Applied Mathematical Sciences, 2014 Let X1, ..., Xn be n independently distributed binomial random variables, each with probability P (Xi = k) = ( mi k ) pi q mi−k i for every k ∈ {0, 1, ...,mi}, where qi = 1− pi. Suppose that N is a positive integer-valued random variable and independent of Xi’s. Let SN = ∑N i=1Xi be the random sums of independent binomial random variables and Pλ denote

POISSON APPROXIMATION FOR INDEPENDENT NEGATIVE BINOMIAL RANDOM VARIABLES [PDF]
International Journal of Pure and Apllied Mathematics, 2014 We give a bound for the total variation distance between the distribution of a sum of independent negative binomial random variables and an appropriate Poisson distribution with mean P n=1 riqi pi , where ri and pi = 1−qi are parameters of each negative binomial distribution.
