The shape phase structure and its transition of the nucleus in the transitional region between the U(5) and SU(3) symmetries is restudied within the framework of coherent-state theory with angular momentum projection in IBM-1. A phase diagram in terms of the deformation parameter and angular momentum is given. The certain angular momentum (or rotation-driven ) effect on the nuclear shape is dis...

Quantum phase transitional behavior of a finite periodic XX spin1 2 chain with nearest neighbor interaction in a uniform transverse field is studied based on the simple exact solutions. It is found that there are [N/2] level-crossing points in the ground state, where N is the periodic number of the system and [x] stands for the integer part of x, when the interaction strength and magnitude of t...

Herein, we address transitional actions class as a class between actions. Transitional actions should be useful for producing short-term action predictions while an action is transitive. However, transitional action recognition is difficult because actions and transitional actions partially overlap each other. To deal with this issue, we propose a subtle motion descriptor (SMD) that identifies ...

Complex fluids that exhibit phenomena such as layering and separation of multiple phases are computationally expensive to model using conventional numerical integration of partial differential equations. Lattice gas approaches are significantly cheaper to simulate and can still reveal good insights into the essential behaviours. We describe simulations of multi-phase layering in a lattice gas b...

A recent analysis of experimental energy systematics suggests that all collective nuclei fall into one of three classes – seniority, anharmonic vibrational, or rotational – with sharp phase transitions between them. We investigate the transition from the seniority to the anharmonic vibrator regime within a shell model framework involving a single large j–orbit. The calculations qualitatively re...

Lymphoepithelial - like carcinoma, is rarely recognized in the urinary bladder and less commonly occurs with papillary transitional cell carcinoma i.e. mixed pattern. Also, less uncommon is the occurrence of carcinoma in situ changes in the adjacent urothelium of these tumors. Here, a case of lymphoepithelial – like carcinoma and papillary transitional cell carcinoma associated with carci...

The concept of critical points in nuclear phase transitional regions is discussed from the standpoints of Q-invariants and wave function entropy. It is shown that these critical points very closely coincide with the turning points of the entropy and Q-invariants, establishing the singular character of these points in nuclear phase transition regions. Such critical points provide two well define...
