Joint Estimation Using Quadratic Estimating Function

Journal of Probability and Statistics, 2011
A class of martingale estimating functions is convenient and plays an important role for inference for nonlinear time series models. However, when the information about the first four conditional moments of the observed process becomes available, the ...

Linear-Quadratic Mean Field Games in Hilbert Spaces

SIAM Journal on Mathematical Analysis
This paper represents the first attempt to develop a theory for linear-quadratic mean field games in possibly infinite dimensional Hilbert spaces. As a starting point, we study the case, considered in most finite dimensional contributions on the topic, where the dependence on the distribution enters just in the objective functional through the mean ...

Design and Characterization of a Two‐Dimensional Soft Array Based on Cooperative Dielectric Elastomer Actuators

Advanced Functional Materials, EarlyView.
A fully polymeric two‐dimensional array of Dielectric Elastomers enables self‐sensing, cooperative actuation, and large‐stroke operation in a DE‐based autonomous conveyor. Based only on voltage and current measurements at actuator level, the system detects the presence of a ball and subsequently drives it toward a target position.

Unified Phase‐Field Framework for Antiferroelectric, Ferroelectric and Dielectric Phases: Application to HZO Thin Films

Advanced Functional Materials, EarlyView.
HfxZr1−xO2${\rm Hf}_x{\rm Zr}_{1-x}{\rm O}_2$ offers CMOS‐compatible nanoscale ferroelectricity yet suffers from a high Ec${\rm E}_c$ demanding large operating voltages. A unified phase‐field framework spanning AFE/FE/DE phases shows how FE grains soften neighboring AFE grains over λ$\lambda$ ≈$\approx$ 22–37 nm.

Optimal inequalities for a Toader-type mean by quadratic and contraharmonic means

Journal of Nonlinear Sciences and Applications, 2017
Summary: In this paper, we present the best possible parameters \(\alpha_i, \beta_i\) (\(i=1,2,3\)) and \(\alpha_4,\beta_4\in(1/2,1)\) such that the double inequalities \[\alpha_1Q(a,b)+(1-\alpha_1)C(a,b)

Counterintuitive Fluorescence Blue Shift in Symmetry Breaking Dicationic Bis(indolium) with Two‐Photon Absorption Properties for NIR Living Cell Imaging

Advanced Materials, EarlyView.
Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.

On Certain Inequalities for Neuman-Sándor Mean

Abstract and Applied Analysis, 2013
We present several new sharp bounds for Neuman-Sándor mean in terms of arithmetic, centroidal, quadratic, harmonic root square, and contraharmonic means.

Mean Values of Quadratic Twists of AutomorphicL-functions

Journal of Number Theory, 1996
Let \(\pi\) be a cuspidal irreducible unitary representation of GL\((r,\mathbb{A}_{\mathbb{Q}})\) which satisfies Ramanujan's conjecture (tempered local components). Assume \(L_f(s,\pi\otimes\chi)\) (``\(f\)'' for ``finite'') satisfies the generalized Riemann hypothesis for all Dirichlet characters \(\chi\) modulo a fixed prime \(q\).

Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

Advanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.
