The visual illusion Terror Subterra, by Roger Shepard (1990), depicts a seemingly large creature chasing another in a tunnel, yet both creatures are physically identical. In addition to this visual illusion, the two creatures also appear to exhibit different emotions, as the background creature (the pursuer) appears angry whereas the foreground creature (the pursued) appears fearful. We explore...

Dexterous physical interactions with virtual creatures are important to bring the fun of playing with animals into arts and entertainment. For reality of interaction, virtual creatures need to react to highly varied user inputs in a variety of ways according to physical and psychological laws. We propose constructing virtual creatures using a physical simulator, sensor/attention models, and phy...

In this paper, we investigate the mass spectrum of ground state hidden-charm tetraquark molecular states without strange, with strange and hidden-strange via QCD sum rules in a comprehensive way revisit assignments [Formula: see text], text] scenario consistently based on rules.

We apply the chiral SU(3) quark mean field model to investigate strange quark matter. The stability of strange quark matter with different strangeness fraction is studied. The interaction between quarks and vector mesons destabilizes the strange quark matter. If the strength of the vector coupling is the same as in hadronic matter, strangelets can not be formed. For the case of β equilibrium, t...

Envenomation by marine creatures is common. As more people dive and snorkel for leisure, the incidence of envenomation injuries presenting to emergency departments has increased. Although most serious envenomations occur in the temperate or tropical waters of the Indo-Pacific region, North American and European waters also provide a habitat for many stinging creatures. Marine envenomations can ...
