Self‐Powered, Ultra‐Sensitive InGaAs/ITO Nanowire Radial Junction Infrared Photodiode for Low Flux Imaging at Room Temperature

open access: yesAdvanced Functional Materials, EarlyView.
This study reports a self‐powered InGaAs nanowire photodetector achieving single‐photon‐level sensitivity in the shortwave infrared at non‐cryogenic temperatures. The device demonstrates high‐speed imaging capabilities even under extremely low‐flux conditions.

Mixture of bivariate Poisson regression models with an application to insurance [PDF]

open access: yes
In a recent paper Bermúdez [2009] used bivariate Poisson regression models for ratemaking in car insurance, and included zero-inflated models to account for the excess of zeros and the overdispersion in the data set. In the present paper, we revisit this

Bistable Isochoric Chiral Metamaterials with Reprogrammable Multiaxial Responses

open access: yesAdvanced Functional Materials, EarlyView.
An isochoric bistable rotational unit cell enables in situ modification of internal contact conditions post‐fabrication, without altering the global envelope dimensions of the surrounding architecture. By selectively switching between open and closed states, the tessellated chiral metamaterial can reprogram its volumetric response, including bulk ...

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.

Ultra‐Thin Tow‐Based Discontinuous Composites—Material Overview and Aspirations

open access: yesAdvanced Functional Materials, EarlyView.
Tow‐based discontinuous composites made from ultra‐thin tapes offer outstanding in‐plane mechanical properties. This material, inspired by Nacre, has high volume fraction of tapes exceeding 90 % and allows for quasi‐isotropic material plates less than 100 micrometer in thickness.

Macrophage–Fibroblast Crosstalk Governs Tumor Mechanics, as Revealed by Spatiotemporal Force Mapping in 3D Spheroids

open access: yesAdvanced Healthcare Materials, EarlyView.
This study shows crosstalk among tumor cells, fibroblasts, and macrophages alters the physical forces inside 3D tumor spheroids. Incorporating deformable microparticles in 3D tumor spheroids, the researchers mapped mechanical stresses spatially and with respect to tumor growth (temporally).

Distributions of Functionals of the two Parameter Poisson-Dirichlet Process [PDF]

open access: yes
The present paper provides exact expressions for the probability distribution of linear functionals of the two–parameter Poisson–Dirichlet process. Distributional results that follow from the application of an inversion formula for a (generalized) Cauchy–
