We propose to use spectator particle yield ratios probe the configuration of α clusters in 12C and 16O by their ultracentral collisions at RHIC LHC energies. The idea is illustrated based on initial density distributions with various α-cluster configurations generated a microscopic cluster model, without from mean-field calculations. multifragmentation matter produces more light nuclei including chain structure clusters, compared those compact structure. ratio free neutrons particles...
Aerodynamic characteristics are the most important standard in field of racing cars. It can not only reflect combination properties vehicles but also highest dynamics. In history, many scientists published some optimized design schemes for For example, Bernoulli and Newton created their aerofoil aerofoil. 1970s, Gordon Murray installed a cooling fan on lower surface car to reduce impact ground. However, these studies focus part have lack integrity. Therefore, it is necessary classify them....
Can relativistic heavy-ion collisions only probe the global shape of colliding nuclei, or their detailed internal structure as well? Taking $^{20}$Ne an example, we attempt to directly its $\alpha$-cluster structure, by comparing experimentally measured observables in at energies from density distributions with and without structure. Since two give same nucleus size deformation, they lead similar mid-rapidity observables. However, may considerably reduce free spectator nucleon yield enhance...

We have investigated the performance of anisotropic flows $\langle v_n^2 \rangle$, transverse momentum fluctuations \delta p_T^2 \rangle $, and their correlations p_T \rangle$ in central collisions at relativistic energies as probes deformation parameters $\beta_n$ colliding nuclei, if these nuclei are light with large different configurations $\alpha$ clusters. The effects from higher-order terms illustrated by derived relations based on overlap two uniform density distributions dynamic...
Lamps installed on stay cables of cable-stayed bridges may alter the configuration circular cross section and therefore result in aerodynamically unstable cable vibrations. The background this study is a preliminary design lamp installation He-dong Bridge Guangzhou, China. Force measurements dynamic response wind tunnel tests were carried out to validate possibility galloping It observed that will occur critical velocity far less than at Guangzhou City stipulated Chinese Code. Numerical...
We investigate the evolution of clustering structure through momentum distributions in $^{8\text{--}10}\mathrm{Be}$ isotopes. The nucleon dynamics within intercluster antisymmetrization are discussed via distribution a Brink type $\ensuremath{\alpha}\text{\ensuremath{-}}\ensuremath{\alpha}$ wave function. For state with small distance, we observe significant depression dip at zero and an enhanced tail relatively higher region. In addition, find ``cluster structure'' intrinsic frame space,...
We investigate the ground-state structures of $^{12\ensuremath{-}14}\mathrm{C}$ isotopes, which exhibit coexistence cluster and shell-like states, using breaking Tohsaki-Horiuchi-Schuck-R\"opke (CB-THSR) wave function. This approach incorporates nucleon-nucleon pairs, making it particularly suitable for describing states that feature mixed configurations dynamic motion. Through variational optimization THSR bases, we find coupling between motions clusters valence neutrons in different e.g.,...
Altruism is an innate aspect of human virtue and represents a capability that humans have evolutionarily developed as social beings. Studies identified moral emotions, such compassion elevation, the mechanisms behind altruistic motivation behavior. While research on emotions has drawn much attention, difficulty in measuring these subtle limited both real-world applications. Advances multimodal emotion recognition technology (MMER) shed light challenges. This study aims to bridge gap...
