Ambient‐Stable Transparent P‐Type CuI Transistors Via Room‐Temperature Pulsed Laser Deposition

Advanced Functional Materials, EarlyView.
An in situ PLD fabricated AlOx${\rm AlO}_x$/CuI/AlOx${\rm AlO}_x$ sandwich structure enables stable CuI TFTs with a field‐effect mobility of 2.3 ±$\pm$ 0.7 cm2${\rm cm}^{2}$ V−1${\rm V}^{-1}$ s−1${\rm s}^{-1}$ and excellent ambient stability. Complementary inverters based on CuI:Rb and ZnO:Al exhibit rail‐to‐rail voltage transfer characteristics and an

Fear of ruin and longevity enhancing investment [PDF]

Rectangularization of the survival probability seems to be an ongoing process. It results from a higher concentration of the ages at death; but it can be reversed by a continuous increase in the limit of life time. In this paper, we assume that these two

Extension of the Risk Model From a Hawkes Variable Memory Process via the Spearman Copula

Journal of Probability and Statistics
The ultimate ruin probability of an insurance company throughout its operating life remains and continues to be a major and very complex concern for the latter.

Nanoscale Spatial Tuning of Superconductivity in Cuprate Thin Films via Direct Laser Writing

Advanced Functional Materials, EarlyView.
Maskless direct laser writing enables local control of oxygen stoichiometry in epitaxial YBCO thin films under ambient conditions. Sub‐micrometer grayscale patterns with tunable optical response and superconducting transport properties are achieved.

Ruin probabilities for the perturbed compound Poisson risk process with investment

, 2011
In this article, we consider the perturbed compound Poisson risk process with investment incomes. The risk reserve process is perturbed by an independent Brownian motion and the surplus is invested at a constant force of interest.

The finite-time ruin probabilities of a dependent bidimensional risk model with subexponential claims and Brownian perturbations

Nonlinear Analysis
The paper considers a dependent bidimensional risk model with stochastic return and Brownian perturbations in which the price processes of the investment portfolio of the two lines of business are two geometric Lévy processes, and the claim-number ...

Two‐Photon Grayscale Lithography (2GL) of High Mechanical and Optical Quality 3D Silica Glass Microstructures

Advanced Functional Materials, EarlyView.
Two‐photon grayscale lithography (2GL) enables high‐speed and precise 3D printing of thermolyzed silica glass microstructures with optical‐grade surface quality, high quality factors, and mechanical strength utilizing a custom‐made pre‐glass resist based on polyhedral oligomeric silsesquioxane (POSS) modified with a high‐sensitivity Norrish type II ...

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

Advanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.

The Gerber-Shiu expected discounted penalty-reward function under an affine jump-diffusion model. [PDF]

We provide a unified analytical treatment of first passage problems under an affine state-dependent jump-diffusion model (with drift and volatility depending linearly on the state).
