Some Properties of the (p,q)-Fibonacci and (p,q)-Lucas Polynomials

open access: yesJournal of Applied Mathematics, 2012
Riordan arrays are useful for solving the combinatorial sums by the help of generating functions. Many theorems can be easily proved by Riordan arrays. In this paper we consider the Pascal matrix and define a new generalization of Fibonacci polynomials ...

Structure‐Property Relationships in Catecholamine Coatings for Broad Surface Functionalization

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by mussel adhesive proteins (MAPs), six catecholamine molecules with different molecular structure were systematically characterized and compared based on their ability to form homogeneous, reactive coatings. Highlighting candidates capable of balancing coating properties of interest, their successful use as primer layers for organic and ...

The w0(p)w0(p)–w0(q)w0(q) mapping problem for factorable matrices I

open access: yes, 2007
We find necessary and sufficient conditions for the class of factorable matrices M(a,b) to map w0(p) into w0(q) for ...

Drop‐on‐Demand Printed Negative Dielectric Anisotropy Liquid Crystal Droplets for Adaptive Complex Beam Manipulation and Assessment

open access: yesAdvanced Functional Materials, EarlyView.
Printed negative‐dielectric‐anisotropy liquid‐crystal droplets enable multidimensional full‐vectorial optical‐field sensing across polarization, phase, and wavelength, while also generating tunable skyrmionic‐like complex optical fields. ABSTRACT Adaptive manipulation of vectorial optical fields is important for optical metrology, imaging, and ...

Regularity for Nonuniformly Elliptic Equations with p,q-Growth and Explicit x,u-Dependence

open access: yes
We are interested in the regularity of weak solutions u to the elliptic equation in divergence form; precisely in their local boundedness and their local Lipschitz continuity under general growth conditions, the so called p,q-growth conditions.

Insulating‐Passivating Interfaces for Narrow‐Bandgap Tin‐Lead Perovskites Enable High‐Photovoltage in Single‐ and Double‐Junction Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Combining field‐effect surface passivation of a narrow‐bandgap tin–lead perovskite by diammonium ions with introducing oleyl‐based amphiphiles to create insulating interface layers between the absorber and the adjacent hole and electron transporting layers increases the open‐circuit voltage to 91.5% of the detailed‐balance limit and enhances the power ...

Tantalum–Palladium Ultrathin Resistance Hydrogen Sensor

open access: yesAdvanced Functional Materials, EarlyView.
Nanoconfined Ta‐alloy thin films enable fast, reversible hydrogen sensing by suppressing unwanted phase transitions. A Ta0.88${\rm Ta}_{0.88}$Pd0.12${\rm Pd}_{0.12}$ sensing layer delivers hysteresis‐free detection from ppb to 100% H2${\rm H}_2$ at room temperature.

Spherical Functions on SO0(p, q)/ SO(p) × SO(q)

open access: yes, 1999
An integral formula is derived for the spherical functions on the symmetric space G/K = SO0(p, q)/ SO(p) × SO(q). This formula allows us to state some results about the analytic continuation of the spherical functions to a tubular neighbourhood of the ...

Topically Delivered Treg‐Attracting Microparticle‐Hydrogel Composites Recruit Regulatory T Cells and Limit Cardiac Injury After Severe Ischemia

open access: yesAdvanced Healthcare Materials, EarlyView.
CCL22‐releasing PLGA microparticles (MP) suspended in topically applied hydrogels (HEART) establish a sustained chemokine gradient at the injured myocardium. HEART recruits CCR4+ regulatory T cells, reduces infarct size and graft fibrosis, and improves cardiac function.
