On a Problem Concerning Permutation Polynomials [PDF]
Transactions of the American Mathematical Society, 1987 If R is the ring of integers in the algebraic number field K and f is a polynomial over R, then f is said to be a permutation polynomial modulo an ideal I (p. p. mod I) of R if the mapping induced on the residue class ring R/I is bijective. Let \(S_ 1(f)\) be the set of nonzero prime ideals P such that f is a p. p. mod P but not mod \(P^ 2\), and let \(

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement
Advanced Science, EarlyView.The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Permutation Polynomials Modulo N
, 2009 Based on preliminary numerical computations, we give complete results for linear and quadratic polynomials. Rivest’s result holds in the linear case while there are plenty of counterexamples in the quadratic case.

Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Boosting Photo‐Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering
Advanced Science, EarlyView.This study reports Ba(Ti0.85Zr0.15)O3 nanocatalysts with enhanced polarization and oxygen‐vacancy‐rich interfaces for efficient NIR‐II photo‐pyroelectric therapy. Zr doping boosts the pyroelectric coefficient and accelerates polarization switching, while oxygen vacancies improve photothermal conversion and surface reactivity.
