A Unified Approach to Some Mixed Poisson Distributions

open access: yes, 2015
[[abstract]]In this paper we derive a new mixed Poisson distribution which includes the negative binomial, Poisson-Lindley, Poisson-Lomax, Poisson-Beta type II, and Poisson-F distributions.

Spatial modelling of claim frequency and claim size in insurance [PDF]

open access: yes, 2005
In this paper models for claim frequency and claim size in non-life insurance are considered. Both covariates and spatial random e ects are included allowing the modelling of a spatial dependency pattern.

Programmable Elastic Wave Control Via Mechanical‐Acoustic Interaction in Bistable Metamaterials

open access: yesAdvanced Science, EarlyView.
A mechanically programmable metamaterial based on mechanical‐acoustic interaction enables reconfigurable elastic wave control through bistable state switching. Spatial encoding of peak and valley states tunes band structures and transmission, achieving low‐frequency vibration suppression, waveguiding, and energy localization.

"On a limiting quasi-multinomial distribution" [PDF]

open access: yes
A random clustering distribution is useful for modeling count data. The present article derives a new distribution of this type from the Lagrangian Poisson distribution, based on the result that any infinitely divisible distribution over nonnegative ...

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

open access: yesAdvanced Science, EarlyView.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

Discrete Poisson Haq distribution with mathematical properties and count data modeling

open access: yesScientific Reports
A new one-parameter discrete distribution, namely the Poisson Haq (PH) distribution, is proposed by a mixture of the Poisson variable and an independently distributed Haq random variable.

Temperature‐Graded Deposition of HfZrOx for Ferroelectric Capacitors With Enhanced Polarization, Reliability, and Switching

open access: yesAdvanced Electronic Materials, EarlyView.
Temperature‐graded ALD of HfZrOx (HZO) enables strain‐enhanced stabilization of the ferroelectric o‐phase, achieving simultaneously high polarization, fast switching, and robust endurance in BEOL‐compatible FeCAPs. ABSTRACT Ferroelectric Hf0.5Zr0.5O2 (HZO) capacitors hold great promise for next‐generation nonvolatile memory and logic applications ...

Predicting and Rationalizing Piezoelectricity in Racemic Bioorganic Molecular Crystals

open access: yesAngewandte Chemie, EarlyView.
Racemic molecular crystals, composed of equal mixtures of chiral enantiomeric components, are predicted to exhibit significant piezoelectric responses and favourable mechanical flexibility. This study identifies organic and bioorganic racemates as promising candidates for sustainable, lead‐free materials, enabling next‐generation applications in energy
