Study of Properties for Ca (a, n)Ti Reactions and n-Yield for Ca Isotopes (A=41-50)
In this study, (44Ti – 53Ti) isotopesfor one of intermediate elements (A>40) from Ca (?, n)Ti reactions with alpha energy from (10 to 50) MeV are used according to the available data of reaction cross sections obtained from Lab (TENDL-2012). The more recent cross sections data of Ca (?, n)Tireaction is reproduced in fine steps of (0.5MeV), by using (MATLAB R2008b) program. These cross section...
Analysis of Stable Isotopic Composition of Precipitation in Katsina State In Nigeria As An Indication of Water Cycle
The seasonal nature of precipitation in recent years had seriously affected the industrial and agricultural activities in Katsina state. Thus, stable isotopes composition of precipitation was used to check water cycle which delineated the nature of precipitation. The phase changing characteristic of water during successive cycle of evaporation and condensation (hydrological cycle) reveals the m...


Using Electrical Stimulation in Diabetic Therapy
This study aimed to find a new technique for diabetic therapy using new device of electrical stimulation by treating 320 cases of diabetic patient divided in four groups. The first was for patients with no drug and herbal therapy. The second group took 1 tablet of (G or D) or 1herbal dose. The third took more than tablet of (G or D) or (1 tablet + 1 herbal dose). The fourth group was treated by...

Methodological demonstration of laser beam pointing control for space gravitational wave detection missions
In space laser interferometer gravitational wave (G. W.) detection missions, the stability of the laser beam pointing direction has to be kept at 10 nrad/√Hz. Otherwise, the beam pointing jitter noise will dominate the noise budget and make the detection of G. W. impossible. Disturbed by the residue non-conservative forces, the fluctuation of the laser beam pointing direction could be a few ...
Data acquisition system with pulse height capability for the TOFED time-of-flight neutron spectrometera)
A new time-of-flightneutronspectrometer TOFED has been constructed for installation at Experimental Advanced Superconducting Tokamak. A data acquisition system combining measurements of flight time and energy from the interaction of neutrons with the TOFED scintillators has been developed. The data acquisition system can provide a digitizing resolution better than 1.5% (to be compared with the ...

Design of the high-resolution soft X-ray imaging system on the Joint Texas Experimental Tokamaka)
A new soft X-raydiagnosticsystem has been designed on the Joint Texas Experimental Tokamak (J-TEXT) aiming to observe and survey the magnetohydrodynamic(MHD) activities. The system consists of five cameras located at the same toroidal position. Each camera has 16 photodiode elements. Three imagingcameras view the internal plasma region (r/a< 0.7) with a spatial resolution about 2 cm. By tomogra...
Alternate Forms of the T-Matrix in Quantum State Tomography
In this paper, we focus on alternate forms of the T-matrix used in theMaximum Likelihood Estimate (MLE) procedure for fitting the experimental datacollected in quantum state tomography experiments. In particular, we analyzethe single quantum state tomography case, deriving in the process three newvalid alternate forms for achieving optimality. These alternative forms thenserve as a consistency ...

Dynamical selforganization of atoms in cavities
Laser-cooled atoms can spontaneously form spatially-ordered structures inoptical resonators when the intracavity field energy exceeds a threshold value. This behaviour results from the mechanical forces associated with superradiantscattering of laser photons into the cavity. We treat the atomic motionsemiclassically and show that, while the onset of spatial ordering depends onthe intracavity ph...
Renyi entropy, stationarity, and entanglement of the conformal scalar
We extend previous work on the perturbative expansion of the Renyi entropy,$S_q$, around $q=1$ for a spherical entangling surface in a general CFT. Applied to conformal scalar fields in various spacetime dimensions, the resultsappear to conflict with the known conformal scalar Renyi entropies. On theother hand, the perturbative results agree with known Renyi entropies in avariety of other theor...

Models and Feedback Stabilization of Open Quantum Systems
At the quantum level, feedback-loops have to take into account measurementback-action. We present here the structure of the Markovian models includingsuch back-action and sketch two stabilization methods: measurement-basedfeedback where an open quantum system is stabilized by a classical controller;coherent or autonomous feedback where a quantum system is stabilized by aquantum controller with ...
Monte Carlo integration over regions in the quantum state space. II
For determining the recently-introduced optimal error regions for quantumstate estimation, which maximize the likelihood for given size of the regionand minimize the size for given credibility [see New J. Phys. 15, 123026(2013)], one needs to evaluate high-dimensional integrals. This can only bedone reliably and efficiently with Monte Carlo methods, which in turn requiregood samplings of the pa...

Semionic resonating valence bond states
The nature of the kagome Heisenberg antiferromagnet (HAFM) is under ongoingdebate. While recent evidence points towards a Z_2 topological spin liquid, theexact nature of the topological phase is still unclear. In this paper, weintroduce semionic Resonating Valence Bond (RVB) states, this is, ResonatingValence Bond states which are in the Z_2 ordered double-semion phase, and studythem using Proj...
