On local semirings induced by topologies: An algebraic approach to the Collatz conjecture
We present an algebraic approach to the Collatz conjecture by studying the topology τf on ℕ induced by the Collatz function f, where the open sets θ ⊂ ℕ satisfy f-1 ( θ ) ⊂ θ .

Salvaging the limb after malignant bone tumor ablation is a tough challenge for a reconstructive surgeon confronting such extensive bone defects. A 40-year-old male without any underlying disease was incidentally diagnosed with a chondrosarcoma over his ...

Interpolating sets in the maximal ideal space of $H^\infty$. [PDF]
Let \(M(H^ \infty)\) be the maximal ideal space (= spectrum) of the Banach algebra of bounded analytic functions on the open unit disk \(\mathbb{D}\). As usual, functions in \(H^ \infty\) are identified with their Gelfand transform. For \(f\in H^ \infty\) let \(Z(f)=\{m\in M(H^ \infty)\): \(f(m)=0\}\) denote its zero set.

dynoGP: Deep Gaussian Processes for Dynamic System Identification
This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Extreme Maximal Ideals of a Partially Ordered Vector Space [PDF]
1. Let V be a partially ordered vector space with an order unit e. It is well known that the class 9W of maximal ideals of V is in one-one correspondence with the class K of normalized positive linear functionals, in the sense that to each MC9Y corresponds a positive linear functional Om with M as its null-space and with OkM(e) = 1.

The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Blaschke inductive limits of uniform algebras
We consider and study Blaschke inductive limit algebrasA(b), defined as inductive limits of disc algebras A(D) linked by a sequence b={Bk}k=1∞ of finite Blaschke products.
