Advanced Healthcare Materials, EarlyView.A two‐phase workflow (OFAT screening followed by central composite design) maps how processing variables tune PFCE‐PLGA nanoparticle size, dispersity, surface charge, loading, and 19F‐MRI signal. In situ, time‐resolved synchrotron SAXS tracks albumin‐corona growth on intact dispersions and reveals PFCE‐dependent adsorption pathways.

Symmetric $*$-polynomials on $\mathbb C^n$
Karpatsʹkì Matematičnì Publìkacìï, 2018 $*$-Polynomials are natural generalizations of usual polynomials between complex vector spaces. A $*$-polynomial is a function between complex vector spaces $X$ and $Y,$ which is a sum of so-called $(p,q)$-polynomials.

The quantum G_2 link invariant
, 1991 We derive an inductive, combinatorial definition of a polynomial-valued regular isotopy invariant of links and tangled graphs. We show that the invariant equals the Reshetikhin-Turaev invariant corresponding to the exceptional simple Lie algebra G_2.

Description of translation-invariant Gibbs measures on a Cayley tree of arbitrary order
Учёные записки Казанского университета: Серия Физико-математические наукиA class of translation-invariant Gibbs measures for models with a continuum of spin values on a Cayley tree was examined. The results show that the problem of describing such measures reduces to studying positive solutions of a nonlinear integral ...

Advanced Materials, EarlyView.Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

Journal of High Energy Physics, 2020 We formulate Q-systems for the closed XXZ, open XXX and open quantum- group-invariant XXZ quantum spin chains. Polynomial solutions of these Q-systems can be found efficiently, which in turn lead directly to the admissible solutions of the corresponding ...

Invariance of polynomial inequalities under polynomial maps
Journal of Mathematical Analysis and Applications, 2016 In this paper, the authors prove the invariance under simple polynomial maps of a few useful (multivariate) polynomial inequalities. They define the \(q\)-coordinates of polynomials \(p\) and show that, for every \(w\), the values \(R_j(w)\) form the coefficients on the standard monomial basis of the Lagrange interpolation polynomial of \(p\) at the ...

Asymmetry of the Ferroelectric Phase Transition in BaTiO3
Advanced Materials, EarlyView.Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

Computing knots by quadratic and cubic polynomial curves
Computational Visual Media, 2020 A new method is presented to determine parameter values (knot) for data points for curve and surface generation. With four adjacent data points, a quadratic polynomial curve can be determined uniquely if the four points form a convex polygon.
