High-Resolution Magic-Angle Spinning (HR-MAS) NMR spectroscopy has become an extremely versatile analytical tool to study heterogeneous systems endowed with liquid-like dynamics. Spinning frequencies of several kHz are however required to obtain NMR spectra, devoid of spinning sidebands, with a resolution approaching that of purely isotropic liquid samples. An important limitation of the method...
General spinning brane bound states are constructed, along with their near-horizon limits which are relevant as dual descriptions of non-commutative field theories. For the spinning D-brane world volume theories with a B-field a general analysis of the gauge coupling phase structure is given, exhibiting various novel features, already at the level of zero angular momenta. We show that the therm...
The dynamical equations for a spinning top are derived in which the orientation is specified by a complex variable using stereographic projection of Poisson’s equations. Necessary and sufficient conditions for Lyapunov stability of the uncontrolled motion of the spinning top are derived using the Energy-Casimir method. Control laws that globally asymptotically stabilize the spinning top to the ...
We consider the anomalous dimension of a certain twist two operator in N = 4 super Yang-Mills theory. At strong coupling and large-N it is captured by the classical dynamics of a spinning D5-brane. The present calculation generalizes the result of Gubser, Klebanov and Polyakov (hep-th/0204051): in order to calculate the anomalous dimension of a bound state of k coincident strings, the spinning ...
We study the holographic principle of the two-point function in the case of a spinning string in the AdS/CFT correspondence. Following the general method proposed by Yoneya et al. for the bulk-boundary correspondence in the large J limit, we study the spinning string solution which starts and ends at the boundary. We then show that the spinning string solution directly gives a two-point functio...
In the future, automated demand response mechanisms will be used as spinning reserve. Demand response in the smart grid must be resilient to cyber-physical threats. In this paper, we evaluate the resilience of demand response when used as spinning reserve in the presence of cyber-physical threats. We quantify this evaluation by correlating the stability of the system in the presence of attacks ...
Equations of motion spinning density for extended objects, and corresponding deviation equations are derived. The problem a variable mass to object is obtained. Spinning fluids may be considered as special case express the objects. Meanwhile, tensor can expressed in terms tetrad formalism General Relativity regarded gauge theory gravity. tensors have been derived using specific type Bazanski La...
