Abstract Assume G is a finite p -group. We prove that if all <m:math xmlns:m="http://www.w3.org/1998/Math/MathML"> <m:msub> <m:mi mathvariant="script">𝒜</m:mi> <m:mn>2</m:mn> </m:msub> </m:math> {\mathcal{A}_{2}} -subgroups of are generated by two elements, then so non-abelian subgroups . By using this result, we classify the -groups which have at least <m:mn>1</m:mn> {\mathcal{A}_{1}} and in intersection every pair distinct equals -subgroups. It turns out such whose converse also almost holds.

In virtual Hand-Object Interaction (HOI) scenarios, the authenticity of hand's deformation is important to immersive experience, such as natural manipulation or tactile feedback. Unrealistic arises from simplified hand geometry, neglect different physics attributes hand, and penetration due imprecise contact handling. To address these problems, we propose PhysHand, a novel simulation model, which enhances realism in HOI. First, construct physiologically plausible layered mesh with...
