A de Casteljau Algorithm for Bernstein type Polynomials based on (p; q)-integers [PDF]
, 2018 In this paper, a de Casteljau algorithm to compute (p; q)-Bernstein Bezier curves based on (p; q)- integers are introduced. The nature of degree elevation and degree reduction for (p; q)-Bezier Bernstein functions are studied.

APPROXIMATION BY BASKAKOV-DURRMEYER OPERATORS BASED ON (p, q)-INTEGERS
, 2018 In the present paper, we introduce a new sequence of linear positive operators based on (p, q)-integers. To approximate functions over unbounded intervals, we introduce Baskakov-Durrmeyer type operators using the (p, q)-Gamma function.

Ground‐State Charge‐Transfer Doping in Donor–Acceptor Semiconducting Polymers
Advanced Functional Materials, EarlyView.This work demonstrates controlled ground‐state charge‐transfer complex formation (GS‐CTC) and doping in a series of diketopyrrolopyrrole‐based donor–acceptor semiconducting polymers paired with a π‐conjugated penta‐t‐butylpentacyanopentabenzo[25]annulene “cyanostar” macrocycle. Complementary experimental techniques show how subtle molecular, electronic,

Strictly Chained (p,q)-Ary Partitions
, 2009 We consider a special type of integer partitions in which the parts of the form p^a*q^b, for some relatively prime integers p and q, are restricted by divisibility conditions.

Controlling Radiative Phonons in the van der Waals Ferroelectric NbOI2
Advanced Materials, EarlyView.Using a simple mirror geometry, this work demonstrates local‐density‐of‐optical‐states control of THz phonon emission in van der Waals ferroelectric NbOI2. By engineering the photonic environment, the phonon Q‐factor, linewidth, peak frequency, and emission intensity are reversibly tuned by over an order of magnitude, revealing radiative phonons as ...

Programmable Functional Silicification of DNA Origami Nanostructures
Advanced Materials, EarlyView.This work introduces additional functionality into silica‐coated DNA origami nanostructures using non‐standard silica precursors. A fluorescent precursor enables enhanced intracellular tracking, while a disulfide‐containing reagent yields redox‐responsive, degradable silica coatings.

Tailoring Symmetry Breaking in Engineered van der Waals Superlattices
Advanced Materials, EarlyView.We pioneer a scheme to tailor superpotentials in graphene based on intrinsic substrate electronic orders rather than twist angle. The resulting superpotential folds graphene's Dirac cones to either Γ$\Gamma$ or K‐points, leading to distinct symmetry behaviors.

L(p,q)-labeling of digraphs [PDF]
, 2009 Given a graph G and two positive integers p,q with p>q an L(p,q)-labeling of G is a function f from the vertex set V(G) to the set of all nonnegative integers such that |f(x)−f(y)|≥p if dG(x,y)=1 and |f(x)−f(y)|≥q if dG(x,y)=2.

Extrinsic Limitations of Stealthy Hyperuniform Devices
Advanced Optical Materials, EarlyView.Stealthy hyperuniform devices exhibit a scattering‐free angular region whose extent follows a simple quenching equation. Experimental measurements confirm this prediction but reveal quenching efficiencies far below theoretical expectations. Multiple scattering and finite‐size effects are quantified, establishing realistic performance limits for ...
