A generative model for molecule generation based on chemical reaction trees [PDF]

open access: yesJournal of Chemical Physics, 2021
To develop useful drugs and materials, chemists synthesize diverse molecules by trying various reactants and reaction routes. Toward automating this process, we propose a deep generative model, called cascaded variational autoencoder (casVAE), for ...

Chemical thinning of peach trees

open access: yesComunicata Scientiae, 2022
Peach tree thinning is essential to harvest quality fruits and to keep balanced production for several years. Manual thinning of peach trees demands much work force and increases production costs. Chemical thinning may be an alternative solution, but efficiency depends on doses and species.

Generation, Ranking and Unranking of Ordered Trees with Degree Bounds [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2016
We study the problem of generating, ranking and unranking of unlabeled ordered trees whose nodes have maximum degree of Δ. This class of trees represents a generalization of chemical trees. A chemical tree is an unlabeled tree in which no node has degree

Chemical Priming with Brassinosteroids to Mitigate Responses of Avocado (Persea americana) Trees to Flooding Stress

open access: yesHorticulturae, 2022
Priming involves the exposure of plants to a mild stress to increase tolerance to a more intense stress in the future. Chemical priming with brassinosteroids reduces the negative effects of flooding on the physiology and survival of some plant species ...

On structural properties of ABC-minimal chemical trees

open access: yesApplied Mathematics and Computation, 2019
The atom-bond connectivity (ABC) index of a connected graph G is defined as A B C ( G ) = ∑ u v ∈ E ( G ) d ( u ) + d ( v ) − 2 d ( u ) d ( v ) , where d(w) is the degree of vertex w in G and E(G) is the set of edges of G. Given greedy trees perturbed by
