Gallium Nitride Semiconductor Resonant Tunneling Transistor

open access: yesAdvanced Science, EarlyView.
Three‐terminal GaN semiconductor resonant tunneling transistors (RTTs), which comprise an double‐barrier AlN/GaN/AlN resonant tunneling diode integrated with a GaN high‐electron‐mobility transistor (HEMT) through epitaxial growth in series and parallel configuraions, respectively.

A pointwise Poisson approximation for independent binomial random variables

open access: yesApplied Mathematical Sciences, 2015
This paper uses the Stein-Chen method and the binomial w-functions to derive a non-uniform bound for the point metric between the distribution of a sum of independent binomial random variables, each with parameters mi and pi, and a Poisson distribution with mean P n=1 mipi. In view of this bound, the Poisson distribution can be used as an approximation

A Wireless, Battery‐Free Artificial Throat Patch with Deep Learning for Emotional Speech Recognition

open access: yesAdvanced Science, EarlyView.
In this work, Xu and co‐workers develop a wireless, battery‐free artificial throat patch system (ATPS) consisting of a carbon nanotube‐based thin‐film strain sensor and a miniaturized flexible printed circuit board, to enable real‐time sensing of throat signals.

Mechanical Overloading‐Induced Nanomineral Crystal Perturbation from the Osteochondral Interface: A Potential Initiator of Osteoarthritis

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Advantages of Accounting for Stochasticity in the Premium Process

open access: yesRisks
In this paper, we study a risk model with stochastic premium income and its impact on solvency risk management. It is assumed that both the premium arrival process and the claim arrival process are modelled by homogeneous Poisson processes, and that the ...
