Motion Capture Dataset for Practical Use of AI-based Motion Editing and Stylization

In this work, we proposed a new style-diverse dataset for the domain of motion style transfer. The motion dataset uses an industrial-standard human bone structure and thus is industry-ready to be plugged into 3D characters for many projects. We claim the challenges in motion style transfer and encourage future work in this domain by releasing the proposed motion dataset both to the public and the market. We conduct a comprehensive study on motion style transfer in the experiment using the state-of-the-art method, and the results show the proposed dataset's validity for the motion style transfer task

Distributed Online Optimization With Dynamic Coupling Constraints Under Time-Varying Communication Delays

This paper considers distributed online optimization with dynamic inequality constraints under time-varying communication delays. A group of agents cooperatively estimates an optimal strategy by exchanging the information on the loss value that is sequentially disclosed to each agent. We develop a distributed primal-dual algorithm for an enlarged multiagent network with delayed agents that handle the delayed information. To analyze the optimality and feasibility of the algorithm, a dynamic regret function and an accumulated fit function are considered. We show that both the dynamic regret and fit functions achieve sublinear bounds even in the presence of communication delays. The numerical example verifies the theoretical claims of the sublinearity of the proposed method

Factors Controlling the Photochemical Two-Electron Water Oxidation Initiated By One-Electron in the Molecular Catalyst Sensitized System for Artificial Photosynthesis

The visible light one-photon-induced two-electron water oxidation forming hydrogen peroxide is one of the most promising methodologies to get through the bottleneck of artificial photosynthesis by molecular catalyst. Al-porphyrins (Al–P) have been found to exhibit the two-electron water oxidation either by electrochemical, photochemical, or photoelectrochemical system upon one-electron oxidation of Al–P. Although the reaction mechanism of the two-electron water oxidation has partly been elucidated, the key process of the reaction cycle as well as the kinetic aspect in detail including each rate constant has not yet been unveiled. Tetra-(N-methyl-4-pyridiniumyl)porphyrinate-Al(III) (AlTMPyP) has the higher reactivity in the electrochemical water oxidation than tetra-(4-carboxyphenyl)porphyrinate-Al(III) (AlTCPP), while AlTCPP is the more reactive than AlTMPyP in the photochemical water splitting into H2O2/H2 in a molecular catalyst sensitized system (MCSS) composed of TiO2 as an electron accepting/conducting wire and Pt clusters on TiO2 as H2 evolution site. To get deeper insight into what factors are controlling the contrasting reactivity among AlTMPyP and AlTCPP adsorbed on semiconductor (SC) such as TiO2 or SnO2, a detailed kinetic study including the dynamic fluorescence lifetime measurements were carried out. Among the four-step reaction mechanism, factors controlling each reaction step were unveiled down to the rate constants of corresponding processes. The nonlinear relation of kinetic data was successfully contrived to make it linearized to elucidate the rate constants. The most crucial factor determining the total photochemical reactivity was revealed to be the charge separation process just after the electron injection from the excited singlet state of Al–P adsorbed on SC. According to either the microscopic band bending of electrostatically attractive potential energy in the case of cationic AlTMPyP or repulsive one for anionic AlTCPP surface appearing near the surface area surrounding Al–P, the injected electron in the CB of SC rapidly slides down to recombine in the attractive potential or escapes inside of the CB in the repulsive potential to determine the charge separation efficiency. Another key factor, the pH jumping effect within the small space between the nanoparticles accompanied by the two-electron water oxidation, which induces the rapid desorption of Al–P from the surface of SC, was also discussed
