Introduction to the polymorphic tracking code: Fibre bundles, polymorphic Taylor types and "Exact tracking" [PDF]

open access: yes, 2002
This is a description of the basic ideas behind the ``Polymorphic Tracking Code'' or PTC. PTC is truly a ``kick code'' or symplectic integrator in the tradition of TRACYII, SixTrack, and TEAPOT.

Easily Calculate TPSA Descriptors from SMILES Strings Using Ruby CDK

open access: yes, 2007
A D-F reader wrote in to ask how to calculate Topological Polar Surface Area (TPSA) using Ruby CDK. TPSA is one of the most widely-used descriptors for predicting membrane permeability and from it other important ADME properties. This article shows how to calculate TPSA with Ruby using Ruby CDK. The Library Our library consists of nothing more than a

Transfert d'énergie par résonance de type Förster entre des complexes de terbium et des boîtes quantiques pour des immunodosages et des reglettes moléculaires multiplexés [PDF]

open access: yes, 2015
Förster resonance energy transfer (FRET) is a non-radiative energy transfer from a donor to an acceptor in close proximity. Due to its extremely sensitive distance dependence in the 1 – 20 nm range, FRET plays an important role in nanobiotechnology ...

Mixed Finite Element and TPSA Finite Volume Methods for Linearized Elasticity and Cosserat Materials

open access: yesECMOR 2024
Cosserat theory of elasticity is a generalization of classical elasticity that allows for asymmetry in the stress tensor by taking into account micropolar rotations in the medium. The equations involve a rotation field and associated "couple stress" as variables, in addition to the conventional displacement and Cauchy stress fields. In recent work, we
