Stability analysis of explicit and semi-implicit derivative-free methods for stochastic differential equations [PDF]

, 2016
This paper is devoted to investigate the mean-square stability of explicit and semi-implicit derivative-free methods to a class of stochastic differential equations (SDEs).

Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

Advanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

Multiplicative uncertainty, central bank transparency and optimal degree of conservativeness [PDF]

This paper extends the results of Kobayashi (2003) and Ciccarone and Marchetti (2009) by considering the optimal choice of central bank conservativeness. It is shown that the government can choose a sufficiently populist but opaque central banker so that

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing

Advanced Functional Materials, EarlyView.
A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

Hybrid error estimates of Weddle's formula and their applications for various classes of functions

Ain Shams Engineering Journal
This study presents new bounds on Weddle's type formula for differentiable functions using proportional Caputo-Hybrid operators (Pcap). These operators provide hybrid estimates; for α=1, they yield first-derivative estimates, while for α=0, they ...

Derivatives of multiple sine functions

Proceedings of the Japan Academy, Series A, Mathematical Sciences, 2004
The author computes the derivatives of multiple sine functions in order to investigate the coefficients appearing in the resulting addition type formula. He also presents explicit expressions and obtain an interesting modular form.

A new mixed multiplicative-additive model for seasonal adjusment [PDF]

Usually, seasonal adjustment is based on time series models which decompose an unadjusted series into the sum or the product of four unobservable components (trendcycle, seasonal, working-day and irregular components).
