Specialized integer factorization [PDF]
, 1998 Vanstone and Zuccherato [3] propose a cryptographic system based on an elliptic curve modulo a composite number. We show that the composite numbers so constructed are easily factored, rendering the system insecure.

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires
Advanced Functional Materials, EarlyView.In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Irreducible polynomials in Int(ℤ)
ITM Web of Conferences, 2018 In order to fully understand the factorization behavior of the ring Int(ℤ) = {f ∈ ℚ[x] | f (ℤ) ⊆ ℤ} of integer-valued polynomials on ℤ, it is crucial to identify the irreducible elements.

Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study
Advanced Functional Materials, EarlyView.This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.

An analogue in certain unique factorization domains of the Euclid-Euler theorem on perfect numbers
International Journal of Mathematics and Mathematical Sciences, 1990 We show that there exists a natural extention of the sum of divisors function to all unique factorization domains F having a finite number of units such that if a perfect number in F is defined to be an integer η whose proper divisors sum to η, then the ...

Advanced Functional Materials, EarlyView.Vacuum‐based deposition is promising for perovskite solar cells to be successfully commercialized. However, co‐evaporation, the most common vapor phase deposition technique, suffers from very low deposition rates. In this work, we reveal that high deposition rates can lead to carbon flakes depositing into the perovskite absorber layers due to material ...

Factorization of cubic vertices involving three different higher spin fields
Nuclear Physics B, 2014 We derive a class of cubic interaction vertices for three higher spin fields, with integer spins λ1, λ2, λ3, by closing commutators of the Poincaré algebra in four-dimensional flat spacetime.
