Neuron type classification in rat brain based on integrative convolutional and tree-based recurrent neural networks.

Sci Rep 2021 Mar 31;11(1):7291. Epub 2021 Mar 31.

Institute of Automation, Chinese Academy of Sciences, Beijing, China.

The study of cellular complexity in the nervous system based on anatomy has shown more practical and objective advantages in morphology than other perspectives on molecular, physiological, and evolutionary aspects. However, morphology-based neuron type classification in the whole rat brain is challenging, given the significant number of neuron types, limited reconstructed neuron samples, and diverse data formats. Here, we report that different types of deep neural network modules may well process different kinds of features and that the integration of these submodules will show power on the representation and classification of neuron types.

Comparison of many-particle representations for selected-CI I: A tree based approach.

J Comput Chem 2021 Mar 25. Epub 2021 Mar 25.

Max-Planck-Institut für Kohlenforschung, Mülheim an der Ruhr, Germany.

The full configuration interaction (FCI) method is only applicable to small molecules with few electrons in moderate size basis sets. One of the main alternatives to obtain approximate FCI energies for bigger molecules and larger basis sets is selected CI. However, due to: (a) the lack of a well-defined structure in a selected CI Hamiltonian, (b) the potentially large number of electrons together with c) potentially large orbital spaces, a computationally and memory efficient algorithm is difficult to construct.

Resilient Consensus of Multiagent Systems Under Malicious Attacks: Appointed-Time Observer-Based Approach.

IEEE Trans Cybern 2021 Mar 22;PP. Epub 2021 Mar 22.

This article aims to establish an appointed-time observer-based framework to efficiently address the resilient consensus control problem of linear multiagent systems with malicious attacks. The local appointed-time state observer is skillfully designed for each agent to estimate the agent's actual state value at the appointed time, even in the presence of unknown malicious attacks. Based on the state estimation, a new kind of resilient control strategy is proposed, where a virtual system is constructed for each agent to generate an ideal state value such that the consensus of normal agents can be achieved with the exchange of ideal state values among neighboring agents.

Simultaneous tree stem and soil greenhouse gas (CO , CH , N O) flux measurements: a novel design for continuous monitoring towards improving flux estimates and temporal resolution.

New Phytol 2021 Mar 19. Epub 2021 Mar 19.

Center of Excellence Global Change Ecology, Department of Biology, University of Antwerp, Universiteitsplein 1, Wilrijk, 2610, Belgium.

Tree stems and soils can act as sources and sinks for the greenhouse gases (GHG) carbon dioxide (CO ), methane (CH ), and nitrous oxide (N O). Since both uptake and emission capacities can be large, especially in tropical rainforests, accurate assessments of the magnitudes and temporal variations of stem and soil GHG fluxes are required. We designed a new flexible stem chamber system for continuously measuring GHG fluxes in a French Guianese rainforest. Read More
