Generating Focused Molecule Libraries for Drug Discovery with Recurrent Neural Networks

open access: yesACS Central Science, 2017
In de novo drug design, computational strategies are used to generate novel molecules with good affinity to the desired biological target. In this work, we show that recurrent neural networks can be trained as generative models for molecular structures ...

Cooperation of Oligodeoxynucleotides and Synthetic Molecules as Enhanced Immune Modulators

open access: yesFrontiers in Nutrition, 2019
Unmethylated cytosine–guanine dinucleotide (CpG) motifs are potent stimulators of the host immune response. Cellular recognition of CpG motifs occurs via Toll-like receptor 9 (TLR9), which normally activates immune responses to pathogen-associated ...

Musielak-Orlicz-Hardy Spaces Associated with Operators Satisfying Reinforced Off-Diagonal Estimates

open access: yesAnalysis and Geometry in Metric Spaces, 2013
Let X be a metric space with doubling measure and L a one-to-one operator of type ω having a bounded H∞ -functional calculus in L2(X) satisfying the reinforced (pL; qL) off-diagonal estimates on balls, where pL ∊ [1; 2) and qL ∊ (2;∞]. Let φ : X × [0;∞) →

Para além das fronteiras da química: relações entre filosofia, psicologia e ensino de química Beyond chemical boundaries: a conceptual profile for molecule and molecular structure

open access: yesQuímica Nova, 1997
The concepts of molecule and of molecular structure are so central to understand chemical phenomena that seems to be no doubt about the uniqueness of its meanings. Nevertheless, the idea that the world exhibits a multiform structure and that to different

Vibrational energy transfer in ultracold molecule - molecule collisions

open access: yes, 2008
We present a rigorous study of vibrational relaxation in p-H2 + p-H2 collisions at cold and ultracold temperatures and identify an efficient mechanism of ro-vibrational energy transfer.

A DFT study of the NO adsorption on Pdn (n = 1–4) clusters [PDF]

open access: yes, 2011
We report a density-functional study of some properties of the adsorption process of the NO molecule on small palladium clusters (n = 1–4). The interaction between NO and the Pdn clusters is studied on various adsorption sites.

Ultrastrong coupling effects in molecular cavity QED

open access: yesNanophotonics, 2020
The spectrum and energy dynamics for a system that comprises a molecule interacting with a cavity photon is analyzed, taking into account the effect of both molecular vibrations and counter-rotating terms (CR) in the dipole Hamiltonian.

Improved maize reference genome with single-molecule technologies

open access: yesNature, 2017
Complete and accurate reference genomes and annotations provide fundamental tools for characterization of genetic and functional variation. These resources facilitate the determination of biological processes and support translation of research findings ...

Dissociation and Decay of Ultra-cold Sodium Molecules

open access: yes, 2003
The dissociation of ultracold molecules is studied by ramping an external magnetic field through a Feshbach resonance. The observed dissociation energy shows non-linear dependence on the ramp speed and directly yields the strength of the atom-molecule ...
