Approximate polymorphisms

open access: yesProceedings of the 54th Annual ACM SIGACT Symposium on Theory of Computing, 2022
For a function $g\colon\{0,1\}^m\to\{0,1\}$, a function $f\colon \{0,1\}^n\to\{0,1\}$ is called a $g$-polymorphism if their actions commute: $f(g(\mathsf{row}_1(Z)),\ldots,g(\mathsf{row}_n(Z))) = g(f(\mathsf{col}_1(Z)),\ldots,f(\mathsf{col}_m(Z)))$ for all $Z\in\{0,1\}^{n\times m}$.

PolyMorph: A P300 Polymorphic Speller [PDF]

open access: yes, 2013
P300 is an electric signal emitted by brain about 300 milliseconds after a rare, but relevant-for-the-user event. Even if it is hard to identify and it provides a low-rate communication channel, it can be used in cases in which other evoked potentials fail.

A polymorph of terephthalaldehyde [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2008
A new ortho-rhom-bic polymorph of terephthalaldehyde, C(8)H(6)O(2), with a melting point of 372 K, has been obtained by recrystallization from ethanol. At room temperature, the crystals transform into the well known monoclinic form, with a melting point of 389 K.

Polymorphism in cyclohexanol [PDF]

open access: yesActa Crystallographica Section B Structural Science, 2008
The crystal structures and phase behaviour of phase II and the metastable phases III′ and III of cyclohexanol, C6H11OH, have been determined using high-resolution neutron powder, synchrotron X-ray powder and single-crystal X-ray diffraction techniques.

Algebraic polymorphisms [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2008
AbstractIn this paper we consider a special class of polymorphisms with invariant measure, the algebraic polymorphisms of compact groups. A general polymorphism is—by definition—a many-valued map with invariant measure, and the conjugate operator of a polymorphism is a Markov operator (i.e.

Polymorphism in Benzamide

open access: yesAngewandte Chemie, 2005
(Figure Presented) At long last, the crystal structure of the metastable form of benzamide, whose existence has been known of for over 170 years, has finally been solved by using a combination of in situ crystallization, high-speed synchrotron X-ray powder diffraction, and global-optimization methods of structure determination (see picture).

POLYMORPHISM AND POLYMORPH CHARACTERISATION IN PHARMACEUTICALS

open access: yesJournal of Biomedical and Pharmaceutical Research, 2019
Polymorphism is the ability of a specific chemical compound to crystallize in more than one crystalline form. Polymorphs had a different arrangement of the molecule in the given crystal lattice and  may properties such as packing properties, thermodynamic properties, spectroscopic properties, kinetic properties, surface properties and mechanical ...

Resource Polymorphism [PDF]

open access: yes, 2018
We present a resource-management model for ML-style programming languages, designed to be compatible with the OCaml philosophy and runtime model. This is a proposal to extend the OCaml language with destructors, move semantics, and resource polymorphism, to improve its safety, efficiency, interoperability, and expressiveness. It builds on the ownership-
