The nonlocal and topological nature of the molecular AharonovBohm (MAB) effect is examined for real electronic Hamiltonians. A notion of preferred gauge for MAB is suggested. The MAB effect in the linear + quadratic E ⊗ ε Jahn-Teller system is shown to be essentially analogues to an anisotropic Aharonov-Casher effect for an electrically neutral spin− 2 particle encircling a certain configuratio...

This paper presents a control scheme for localizing and encircling a target using a multi-robot system. The task is achieved in a distributed way, in that each robot only uses local information gathered by on-board relative-position sensors assumed to be noisy, anisotropic, and unable to detect the identity of the measured object. Communication between the robots is provided by limited-range tr...

Change in impedance of an encircling coil is obtained in the present paper for the case where the electric conductivity and magnetic permeability of a metal cylindrical tube depend on the radial coordinate. The system of equations for the vector potential is solved by means of the Fourier cosine transform. The solution is expressed in terms of improper integral containing modified Bessel functi...

An anomalous origin of the left circumflex coronary artery that arises as a side branch of the right coronary artery from the right coronary sinus of Valsalva encircling the aortic annulus is usually an incidental finding. However, in patients undergoing aortic valve procedures, its existence can significantly complicate the surgical treatment. We report our operative strategy in patients with ...

The ultrastructure of chromosomes from tissue culture cells blocked in division with vincristine sulphate or colchicine was examined. Kinetochores had a distinctive morphology consisting of trilaminar dense plates closely applied to the chromosomes. In longitudinal sections, kinetochores appeared as separate plates attached to opposite sides of the chromosomes. In transverse sections of some pr...

A strong–metal support interaction construction was induced via ultrasonication in water as described by Zhenzhen Yang, Sheng Dai et al. their Communication (e202214322). The encapsulation degree of metal nanoparticles reducible oxide overlayers can be modulated the parameters. facile tunability offers enhanced activity and selectivity diverse catalytic hydrogenation applications. cover picture...

Consider a search game with an immobile hider in a graph. A Chinese postman tour is a closed trajectory which visits all the points of the graph and has minimal length. We show that encircling the Chinese postman tour in a random direction is an optimal search strategy if and only if the graph is weakly Eulerian (i.e it consists of several Eulerian curves connected in a tree-like structure).

However, the use of the term parahemorheology has been criticized, because the prefix para implies that the rheology of fluids and structures in the perivascular spaces is secondary and less important than that of the vessel-blood organ. It is also imprecise, once it does not refer to the fluids and structures being considered. By contrast, the term perihemorheology implies the rheology of flui...

We report a case of an 11-year with recurrent episodes of abdominal pain and vomiting. Diagnostic laparoscopy during a severe episode demonstrated an anomalous blood vessel incompletely encircling the bowel, leading to transient partial small bowel obstruction. This likely represents a remnant vessel from the omphalomesenteric duct. Recurrent abdominal pain and vomiting in the pediatric populat...

We study the fast rotation limit for a Bose-Einstein condensate in a quadratic plus quartic confining potential within the framework of the two dimensional Gross-Pitaevskii energy functional. As the rotation speed tends to infinity, the condensate undergoes a phase transition to the socalled giant vortex state: an annulus with pure irrotational flow encircling a central low-density hole around ...
