Differences in the thermodynamic functions between the liquid and crystalline states of La-based bulk metallic glasses alloys were calculated with the specific heat capacity Cp and the fusion heat ΔHf,which we measured. Fragility indexes having different thermodynamic definitions were calculated from the temperature dependence of excess entropy ΔSliq-cry. It is ambiguous for La-based glass-forming liquid to evaluate fragility from the intercepts of ΔSliq-cry-temperature curves. We found that the thermodynamic fragility MΔS,denoted ΔS,decreases at the onset melting temperatures Tm rather than at glass transition temperatures Tg,and relates linearly with the kinetic fragility m. The correlations between thermodynamic fragility and kinetic fragility are discussed within the frameworks of the Adam-Gibbs relationship and potential energy landscape theory.

Background Synthesizing dance motions to match musical inputs is a significant challenge in animation *** to functional human motions,such as locomotion,dance motions are creative and artistic,often influenced by music,and can be independent body language *** choreography requires motion content to follow a general dance genre,whereas dance performances under musical influence are infused with diverse impromptu motion *** the high expressiveness and variations in space and time,providing accessible and effective user control for tuning dance motion styles remains an open *** In this study,we present a hierarchical framework that decouples the dance synthesis task into independent *** use a high-level choreography module built as a Transformer-based sequence model to predict the long-term structure of a dance genre and a low-level realization module that implements dance stylization and synchronization to match the musical input or user *** novel framework allows the individual modules to be trained *** of the decoupling,dance composition can fully utilize existing high-quality dance datasets that do not have musical accompaniments,and the dance implementation can conveniently incorporate user controls and edit motions through a decoder *** module is replaceable at runtime,which adds flexibility to the synthesis of dance *** Synthesized results demonstrate that our framework generates high-quality diverse dance motions that are well adapted to varying musical conditions and user controls.
