Abstract The bacterium Corynebacterium glutamicum is utilized during industrial fermentation to produce amino acids such as l ‐glutamate. During ‐glutamate fermentation, C . changes the flux of central carbon metabolism favor production, but molecular mechanisms that explain these remain largely unknown. Here, we found profiles two major lysine acyl modifications were significantly altered upon glutamate overproduction in ; acetylation decreased, whereas succinylation increased. A label‐free...
Designing molecular p–n heterojunction structures, i.e., electron donor–acceptor contacts, is one of the central challenges for further development organic electronic devices. In present study, a well-defined two representative semiconductors, pentacene and C60, formed on single-crystal surface precisely investigated in terms its growth behavior crystallographic structure.

The electronic structures of the highest occupied molecular orbital (HOMO) or HOMO-derived valence bands dominate transport nature positive charge carriers (holes) in organic semiconductors. In present study, valence-band single-crystal pentacene and temperature dependence their energy–momentum dispersion relations are successfully demonstrated using angle-resolved ultraviolet photoelectron spectroscopy (ARUPS). For shallowest band, intermolecular transfer integral effective mass holes...
The damage process of composite materials, such as short fiber-reinforced plastics (SFRP), is complex. Therefore, it necessary to accurately represent the in fatigue life prediction. Herein, prediction was conducted by combining digital image correlation method, which a non-destructive testing technique, with convolutional neural network (CNN), using Xception architecture. High accuracy obtained when training and were performed on same SFRP specimens. In contrast, different specimens for...
Middle-carbon martensite steels are vital materials for mechanical components and their properties have attracted significant interest.

Such a pathway-finding problem can be formulated constrained combinatorial optimization problem, aiming to find an combination of reactions connecting starting materials target given network. Due explosion, the computation time required increases exponentially network size. Ising machines, including...
Chemical reactions are regarded as transformations of chemical structures, and the question which atoms in reactants correspond to products has attracted chemists for a long time. Atom-to-atom mapping (AAM) is procedure that establishes such correspondence(s) between reaction. Currently, automatic AAM tools play pivotal role various chemoinformatics tasks. However, achieving accurate complex or unknown within reasonable computation time remains significant challenge due combinatorial nature...

We discuss stability of 3D grasps by using a three-dimensional spring model (3D model). Many works have described frictionless grasp. These used one-dimensional (1D model) for representation contact as matter course. However, 1D involves the following problems: (i) displacement finger is restricted to one dimension along initial normal at point; and (ii) it not clearly considered that generates force object direction only. To overcome problems provide accurate grasp stability, we introduce...
