Combinatorial summation of Feynman diagrams [PDF]

open access: yesNature Communications
Feynman’s diagrammatic series is a common language for a formally exact theoretical description of systems of infinitely-many interacting quantum particles, as well as a foundation for precision computational techniques.

Three-dimensional digital technology-assisted precise tumor resection and reconstruction of the femoral trochanter and postoperative functional recovery: a retrospective study

open access: yesIntelligent Medicine, 2023
Background: The trochanter of the femur is a common site for bone tumors. However, locating the specific boundary of bone tumor infiltration and determining the surgical method can be challenging.

Application of a computer‐assisted structure elucidation program for the structural determination of a new terpenoid aldehyde with an unusual skeleton [PDF]

open access: yesMagnetic Resonance in Chemistry, 2016
AbstractThe structure of a novel compound from Adansonia digitata has been elucidated, and its 1H and 13C NMR spectra have been assigned employing a variety of one‐dimensional and two‐dimensional NMR techniques without degradative chemistry. The Advanced Chemistry Development ACD/Structure Elucidator software was important for determining part of this ...

CodeSkelGen: a program skeleton generator [PDF]

open access: yes, 2013
Existent computer programming training environments help users to learn programming by solving problems from scratch. Nevertheless, initiating the resolution of a program can be frustrating and demotivating if the student does not know where and how to ...

High-level programming of stencil computations on multi-GPU systems using the SkelCL library [PDF]

open access: yes, 2014
The implementation of stencil computations on modern, massively parallel systems with GPUs and other accelerators currently relies on manually-tuned coding using low-level approaches like OpenCL and CUDA.

REKEST: a Computer Program to REsearch for the KEy STep of a Synthesis - Application to Strategies for Building the Longifolene Skeleton

open access: yesCHIMIA, 1986
We describe the program REKEST (REsearch for the KEy STep) the aim of which is to research the key step of a synthesis by dissecting the target molecule according to formal schemes. These schemes represent generalized reactions which allow to delete and/or add one or several bonds in the target compound.

Towards High-Level Programming of Multi-GPU Systems Using the SkelCL Library [PDF]

open access: yes, 2012
Application programming for GPUs (Graphics Processing Units) is complex and error-prone, because the popular approaches — CUDA and OpenCL — are intrinsically low-level and offer no special support for systems consisting of multiple GPUs.

SkelCL: enhancing OpenCL for high-level programming of multi-GPU systems [PDF]

open access: yes, 2013
Application development for modern high-performance systems with Graphics Processing Units (GPUs) currently relies on low-level programming approaches like CUDA and OpenCL, which leads to complex, lengthy and error-prone programs.

Avoiding and identifying errors in health technology assessment models: qualitative study and methodological review

open access: yesHealth Technology Assessment, 2010
Background: Health policy decisions must be relevant, evidence-based and transparent. Decision-analytic modelling supports this process but its role is reliant on its credibility.
