Employment of electric torch discharge and a steam-gas generator in surface schooping of materials [PDF]

Радиофизика и электроника, 2020
Subject and Purpose. The present paper is concerned with the method of surface schooping of materials using high-frequency torch discharge (HFTD) and glycerol vapor as a base for dissolving activating additives to the working gas. To approach the problem,

A molecule perturbation software library and its application to study the effects of molecular design constraints

Journal of Cheminformatics, 2023
Computational molecular design can yield chemically unreasonable compounds when performed carelessly. A popular strategy to mitigate this risk is mimicking reference chemistry.

Back translation for molecule generation

Bioinformatics, 2021
AbstractMotivationMolecule generation, which is to generate new molecules, is an important problem in bioinformatics. Typical tasks include generating molecules with given properties, molecular property improvement (i.e. improving specific properties of an input molecule), retrosynthesis (i.e.

Masked Graph Modeling for Molecule Generation [PDF]

Nature Communications, 2020
De novo, in-silico design of molecules is a challenging problem with applications in drug discovery and material design.Here, we introduce a masked graph model which learns a distribution over graphs by capturing all possible conditional distributions over unobserved nodes and edges given observed ones.We train our masked graph model on existing ...

Score-Based Generative Models for Molecule Generation

CoRR, 2022
Recent advances in generative models have made exploring design spaces easier for de novo molecule generation. However, popular generative models like GANs and normalizing flows face challenges such as training instabilities due to adversarial training and architectural constraints, respectively.

COMA: efficient structure-constrained molecular generation using contractive and margin losses

Journal of Cheminformatics, 2023
Background Structure-constrained molecular generation is a promising approach to drug discovery. The goal of structure-constrained molecular generation is to produce a novel molecule that is similar to a given source molecule (e.g. hit molecules) but has
