The purpose of the present paper is to provide proofs of some of the results announced in the survey paper [13]. These results deal with combinatorial topology, in particular with complexes associated with posets of subgroups of a finite group. For applications to group theory, the reader can refer to the above mentioned paper [13]. In his influential paper [11], Quillen proved that the poset S...

The bulk of spontaneous basal ganglia hemorrhages result from rupture of the small perforating intracerebral arteries and a clinical background of hypertension. Charcot and Bouc hard [1] noted that most microaneurysms occurred in hypertensive brains due to miliary microaneurysms involving branches of lenticu lostriate and thalamoperforating arteries. Such microaneurysms were subsequently demons...

To accurately characterize the mechanical behavior of magnetorheological elastomer (MRE) under a wide range strain amplitude, excitation frequency, and magnetic field, viscoelastic fractional derivative was introduced, modified Bouc-Wen model based on for MRE in nonlinear region established. The can describe hysteretic characteristics region, but it cannot simulate magneto-viscoelasticity frequ...

In the marine environment, naval vessels are often influenced by underwater compression waves. Transport and dangerous goods require advanced protection beyond linear, static considerations. Therefore with regard to shock influence, dynamic characteristics of helical wire-cable-isolators investigated. The impact is given basepoint acceleration measurement data exciting a mechanical model observ...
