Direct Synthesis of High‐Valence Protein@UiO‐66 Composites: Linking Crystallization Pathways to Protein Encapsulation

open access: yesAdvanced Materials, EarlyView.
This work reports a direct, biocompatible method to synthesize UiO‐66, enabling one‐step encapsulation of proteins without compromising crystallinity or activity. Using advanced in situ and ex situ techniques, the study reveals that proteins integrate concurrently with MOF growth, forming crystalline protein@UiO‐66 nanoparticles, and provide insight ...

A Limit Relation for Dunkl-Bessel Functions of Type A and B

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
We prove a limit relation for the Dunkl-Bessel function of type BN with multiplicity parameters k_1 on the roots ±ei and k_2 on ±e_i±e_j where k_1 tends to infinity and the arguments are suitably scaled.

Quantum random walks in one dimension via generating functions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
We analyze nearest neighbor one-dimensional quantum random walks with arbitrary unitary coin-flip matrices. Using a multivariate generating function analysis we give a simplified proof of a known phenomenon, namely that the walk has linear speed rather ...

Asymptotic resemblance [PDF]

open access: yesRocky Mountain Journal of Mathematics, 2016
Uniformity and proximity are two different ways for defining small scale structures on a set. Coarse structures are large scale counterparts of uniform structures. In this paper, motivated by the definition of proximity, we develop the concept of asymptotic resemblance as a relation between subsets of a set to define a large scale structure on it.

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Asymptotic integration of functional differential systems with oscillatory decreasing coefficients: a center manifold approach

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
In this paper we study the asymptotic integration problem in the neighborhood of infinity for a certain class of linear functional differential systems. We propose a method for construction of the asymptotics of solutions in the critical case.

A new method for computing asymptotics of diagonal coefficients of multivariate generating functions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
Let $\sum_{\mathbf{n} \in \mathbb{N}^d} F_{\mathbf{n}} \mathbf{x}^{\mathbf{n}}$ be a multivariate generating function that converges in a neighborhood of the origin of $\mathbb{C}^d$. We present a new, multivariate method for computing the asymptotics of

Quasi-asymptotics and \(S\)-asymptotics of ultradistributions

open access: yesBulletin, Classe des Sciences Mathématiques et Naturelles, Sciences mathématiques, 1995
Summary: The notions of the quasi-asymptotics and the \(S\)-asymptotics at infinity are extended from the space of Schwartz's distributions to the space of ultradistributions. Some basic properties and the relation between these two types of asymptotics are proved.

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment

open access: yesAdvanced Materials, EarlyView.
ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...

Uniqueness of polynomial canonical representations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
Let $P(z)$ and $Q(y)$ be polynomials of the same degree $k \geq 1$ in the complex variables $z$ and $y$, respectively. In this extended abstract we study the non-linear functional equation $P(z)=Q(y(z))$, where $y(z)$ is restricted to be analytic in a ...
