Self-ordered nanospike porous alumina fabricated under a new regime by an anodizing process in alkaline media

open access: yesScientific Reports, 2021
High-aspect ratio ordered nanomaterial arrays exhibit several unique physicochemical and optical properties. Porous anodic aluminum oxide (AAO) is one of the most typical ordered porous structures and can be easily fabricated by applying an ...

The structure of the Mitchell order – II [PDF]

open access: yesAnnals of Pure and Applied Logic, 2015
We isolate here a wide class of well founded orders called tame orders and show that each such order of cardinality at most $κ$ can be realized as the Mitchell order on a measurable cardinal $κ$, from a consistency assumption weaker than $o(κ) = κ^+$.

Ordered/Disordered Structures of Water at Solid/Liquid Interfaces

open access: yesCrystals, 2023
Experiments and theory have revealed versatile possible phases for adsorbed and confined water on two-dimensional solid surfaces, which are closely related to the aspects of various phenomena in physics, chemistry, biology, and tribology. In this review,

On the Structure of Order Domains

open access: yesFinite Fields and Their Applications, 2002
The idea of an order function originated with the second author [\textit{R. Pellikaan}, J. Stat. Plann. Inference 94, No.~2, 287-301 (2001; Zbl 0981.94055)] as a way to consider one-point Goppa codes using ring theory, without using algebraic geometry. An order function generalizes the order of pole of a rational function along a prime divisor.

Cryo-ET detects bundled triple helices but not ladders in meiotic budding yeast

open access: yesPLoS ONE, 2022
In meiosis, cells undergo two sequential rounds of cell division, termed meiosis I and meiosis II. Textbook models of the meiosis I substage called pachytene show that nuclei have conspicuous 100-nm-wide, ladder-like synaptonemal complexes and ordered ...

The quasiparticle band structures of ordered NixPt1-x

open access: yesHeliyon, 2018
The quasiparticle band structures of the ordered L12 and L10 phases of NixPt1-x (x = 0.25, 0.5, and 0.75) have been calculated and compared to the band structures obtained using density functional theory.

Characterizing some regularities of ordered semigroups by their anti-hybrid ideals [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2022
We focus on mappings called hybrid structures. A hybrid structure can be regarded as a combination of a soft set and a fuzzy set. Therefore, with the help of the products of union softs sets and fuzzy sets, we can define a new product of hybrid ...

Monotone subsequence via ultrapower

open access: yesOpen Mathematics, 2018
An ultraproduct can be a helpful organizing principle in presenting solutions of problems at many levels, as argued by Terence Tao. We apply it here to the solution of a calculus problem: every infinite sequence has a monotone infinite subsequence, and ...
