CALPUCK: An Open Python Tool for Cremer–Pople Ring Puckering Analysis Including a New 2D Mapping of Seven‐Membered Rings [PDF]
ChemPlusChem, Volume 91, Issue 6, June 2026.CALPUCK is a free, open‐source Python tool for Cremer–Pople puckering analysis of five‐, six‐, and seven‐membered rings. It introduces a novel two‐dimensional mapping for seven‐membered systems, enabling intuitive visualization of their complex conformational landscapes and facilitating rapid classification of ring conformers.

Addition theorems for dense subspaces [PDF]
, 2015 summary:We study topological spaces that can be represented as the union of a finite collection of dense metrizable subspaces. The assumption that the subspaces are dense in the union plays a crucial role below.

Alexandroff duplicate and βκ [PDF]
, 2022 [EN] We discuss spaces and the Alexandroff duplicates of those spaces that admit a C-S embedding into the Cech-Stone compactification of a discrete space.Szymanski, AA. (2022). Alexandroff duplicate and βκ. Applied General Topology. 23(1):225-234. https:

Continuous utility functions on submetrizable hemicompact k-spaces [PDF]
, 2009 Some theorems concerning the existence of continuous utility functions for closed preorders on submetrizable hemicompact k-spaces are proved. These spaces are precisely the inductive limits of increasing sequences of metric compact subspaces and in ...

, 2003 We prove that the hyperspace of closed bounded sets with the Hausdor_ topology, over an almost convex metric space, is an absolute retract. Dense subspaces of normed linear spaces are examples of, not necessarily connected, almost convex metric spaces ...

On dense subspaces satisfying stronger separation axioms [PDF]
, 1996 summary:We prove that it is independent of ZFC whether every Hausdorff countable space of weight less than $c$ has a dense regular subspace. Examples are given of countable Hausdorff spaces of weight $c$ which do not have dense Urysohn subspaces. We also

Some observations on filters with properties defined by open covers [PDF]
, 2015 summary:We study the relation between the Hurewicz and Menger properties of filters considered topologically as subspaces of $\mathcal{P}(\omega)$ with the Cantor set ...

Disconnection in the Alexandroff duplicate [PDF]
, 2021 [EN] It was demonstrated in [2] that the Alexandroff duplicate of the Čech-Stone compactification of the naturals is not extremally disconnected. The question was raised as to whether the Alexandroff duplicate of a non-discrete extremally disconnected ...

, 2011 We discuss the solution of the fault detection problem for parameter uncertain nonlinear systems using a gain scheduling based approach. By using a set of linearized plant models, a set of least order linear fault detection filters is determined to serve
