Spectral Analysis of Polynomial Nonlinearity with Applications to RF Power Amplifiers
EURASIP Journal on Advances in Signal Processing, 2004 The majority of the nonlinearity in a communication system is attributed to the power amplifier (PA) present at the final stage of the transmitter chain.

On Polynomials Which Commute with a Given Polynomial [PDF]
Proceedings of the American Mathematical Society, 1972 By extending a theorem of Jacobsthal, the following result is obtained: if g is a nonlinear polynomial, there is an integer J ( g ) ≧ 1 J(g) \geqq 1 such that for each m > 0 m > 0 there are either J ( g )

Advanced Functional Materials, EarlyView.Herein, the topochemical transformation of cobalt‐based layered hydroxides into nanocomposites is investigated using advanced real‐time characterization techniques combined with thermogravimetric analysis. The study reveals how interlayer carboxylic acids direct the transformation pathway, highlighting the role of carbon content and anion length. These

On difference polynomials and hereditarily irreducible polynomials
Journal of Number Theory, 1980 AbstractA difference polynomial is one of the form P(x, y) = p(x) − q(y). Another proof is given of the fact that every difference polynomial has a connected zero set, and this theorem is applied to give an irreducibility criterion for difference polynomials. Some earlier problems about hereditarily irreducible polynomials (HIPs) are solved.

Rapid Deep Vat Printing Using Photoclickable Collagen‐Based Bioresins
Advanced Healthcare Materials, EarlyView.Collagen‐based resin formulations based on thiol‐ene photoclick chemistry are demonstrated. These resins enable easy handleability under neutral conditions and further allow facile fabrication of multicellular tissue constructs via tomographic or FLight printing.

Discrete Mathematics, 1988 This important paper generalizes techniques from association schemes and spherical designs to study finite subsets of polynomials spaces. A polynomial space is a set \(\Omega\) with a function \(\rho: \Omega\times\Omega\to {\mathbf R}\) with \(\rho(x,x)=r>0\), \(\rho(x,y)=\rho(y,x)

Advanced Healthcare Materials, EarlyView.Gelatin methacryloyl (GelMA) granular hydrogel scaffolds (GHS) are fabricated using a generalized two‐step photocrosslinking approach to yield stable (non‐dissolving) microgels suitable for in situ covalent assembly under physiological conditions. A phase diagram is developed to define the interplay between individual microgel stability and scaffold ...

On Polynomials Associated with Finite Topologies
AxiomsLet τ be a topology on the finite set Xn. We consider the open-set polynomial associated with the topology τ. Its coefficients are the cardinalities of sets Uj=Uj(τ) of open sets of size j=0,…,n.
