Generating holistic co-speech gestures that integrate full-body motion with facial expressions suffers from semantically incoherent coordination on body motion and spatially unstable meaningless movements due to existing part-decomposed or frame-level regression methods, We introduce 3DGesPolicy, a novel action-based framework that reformulates holistic gesture generation as a continuous trajectory control problem through diffusion policy from robotics. By modeling frame-to-frame variations as unified holistic actions, our method effectively learns inter-frame holistic gesture motion patterns and ensures both spatially and semantically coherent movement trajectories that adhere to realistic motion manifolds. To further bridge the gap in expressive alignment, we propose a Gesture-Audio-Phoneme (GAP) fusion module that can deeply integrate and refine multi-modal signals, ensuring structured and fine-grained alignment between speech semantics, body motion, and facial expressions. Extensive quantitative and qualitative experiments on the BEAT2 dataset demonstrate the effectiveness of our 3DGesPolicy across other state-of-the-art methods in generating natural, expressive, and highly speech-aligned holistic gestures.
We present early results from a high-resolution analysis (similar to 100-200 pc) of the CO(2-1)/CO(1-0) line ratio in 12 nearby galaxies. We use new Atacama Large Millimeter/submillimeter Array (ALMA) CO(1-0) observations from the Fundamental CO(1-0) Transition Survey (FACTS), and re-imaged CO(2-1) data from PHANGS. We make empirical classifications based on the optical and molecular gas morphologies, which show clear systematic trends in the variation of R21 as a function of galactic structure. The sample includes barred, unbarred, and flocculent galaxies. The barred spiral galaxies follow a general trend when the gas exists significantly: R21 is high in the center, low along the bar, increases at the bar ends, and then lowers beyond the bar end or flattens in the outer parts of the disk. The structure dependence suggests the importance of galactic dynamics on molecular gas evolution, and consequently on star formation, in galaxies. R21 fluctuates in the spiral arms for both barred and unbarred galaxies. Areas around HII regions in some cases appear to show more high-ratio gas. Together, R21 varies systematically as a function of galactic structure, dynamics, and star formation activity.
We discuss in this paper thermodynamic properties of relativistic shock waves of arbitrary large magnitude. In the mathematical formulation, thermodynamic variables of the front and back sides of a shock front satisfy a single algebraic equation called the Rankine-Hugoniot thermodynamic condition. However a solution to the equation does not always represent an actual shock wave which has two particular properties: first, its wave front is supersonic relative to the flow ahead of it and subsonic behind it; second, the entropy of the medium behind the shock front exceeds the entropy ahead of it. Thus it is a mathematical problem to select physically admissible solutions. For general non-relativistic gases governed by general equations of state, this problem is solved by Bethe, H. A.: On the theory of shock waves for an arbitrary equation of state, Report No. 545 for the Office of Scientific Research and Development, Serial No. NDRC-B-237, May 4 (this report is available at )(1942) https://link.springer.com/chapter/10.1007/978-1-4612-2218-7_11 and Weyl, H.: Shock waves in arbitrary fluids, Comm. Pure Appl. Math., 5: 103-122 (National Defence Research Committee, Applied Mathematics Panel note, No. 12, Applied Mathematics Group – New York University, No. 46, 1944) (1949) in satisfying ways under reasonable conditions. The aim of this paper is to find thermodynamic conditions which provide an answer to the above problem for relativistic gases. All the conditions are described in terms of thermodynamic invariants. Since Weyl’s theorem is studied by Israel, W.: Relativistic theory of shock waves, Proc. Roy. Soc. London, Ser A 259, 129–143 (1960) , we will focus on Bethe’s theorem. It is interesting to note that Bethe’s condition yields the weak condition of Menikoff, R., Plohr, B.J.: The Riemann problem for fluid flow of real materials. Rev. Modern Phys. 61(1), 7–130 (1989) .
In embedded system industry in Japan, few young engineers have a comprehensive understanding the important embedded software skills that determine the product performance, especially interrupt processing skill. As a result, this is a factor that causes a failure. I propose a curriculum for the purpose to improve this problem and method to verify the training effect.
