We consider blow-out bifurcations of synchronous chaotic attractors on invariant subspaces in coupled chaotic systems with symmetries. Through a blow-out bifurcation, the synchronous chaotic attractor becomes unstable with respect to perturbations transverse to the invariant subspace, and then a new asynchronous chaotic attractor may appear. However, the system symmetry may be preserved or viol...

Hyoid fractures in athletes are rare injuries that can be difficult to diagnose. Typically resulting from a direct blow to the anterior neck, hyoid fractures can lead to subcutaneous edema and subsequent airway compromise. The treatment of this fracture depends largely on the severity of the presenting symptoms. Generally, these fractures do not require surgical intervention but warrant close o...

‎This note deals with the systems of parabolic equations with local and localized sources involving $n$ components‎. ‎We obtained the exponent regions‎, ‎where $kin {1,2,cdots,n}$ components may blow up simultaneously while the other $(n-k)$ ones still remain bounded under suitable initial data‎. ‎It is proved that different initial data can lead to different blow-up phenomena even in the same ...
