We present a fully analytical description of many-body localization (MBL) transition in microscopically defined model. Its Hamiltonian is the sum one- and two-body operators, where both contributions obey maximum-entropy principle have no symmetries except Hermiticity (not even particle number conservation). These two criteria paraphrase that our system variant Sachdev-Ye-Kitaev will demonstrat...

Stretchable woven chute is a safe device for falling humans from multi-story buildings in emergencies. During the fall, the elastomeric property of the fabric, in the weft direction, causes radial forces towards the human body inside .These radial forces lead to frictional forces between the chute and the body. The falling man can reduce the falling speed by exerting outward forces via stretchi...

The dynamic characteristics of deflectable nose missiles with rotary single-channel control were investigated in this paper. Firstly, the effective angle of attack, effective angle of sideslip and quasi-body coordinates were introduced based on the spin characteristics of the missile’s body. Secondly, considering the interaction between the missile’s nose and body, the rigid kinetic model of mi...
