چکیده
The strangeness s = +1 pentaquark states as qqqqq̄ clusters are investigated in this letter. Starting from the inherent geometric symmetry, we analyzed the inherent nodal structure of the system. As the nodeless states, the low-lying states are picked out. Then the S-wave state (J , T ) = (12 − , 0) and P-wave state (J , T ) = (12 + , 0) may be the candidates of low-lying pentaquark states. By comparing the accessibility of the two states and referring the presently obtained K-N interaction potential, we propose that the quantum numbers of the observed pentaquark state Θ+ may be (J , T ) = (12 + , 0) and L = 1.

New model of computer analysis for assessment of the effects of lesions induced by direct voltage current in isolated AV-node of rabbit
Introduction: The ablation technique is one of the important therapeutic interventions for treatment of AV Nodal tachyarrhythmia. Different animal models have been developed to study the effects of ablation on the functional interanodal structure. The aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbi...
متن کاملFluid-structure Interaction Vibration Analysis of Vertical Cylindrical Containers with Elastic Bottom Plate Made of Functionally Graded Materials
In the present paper a method is proposed to investigate the free vibration of a partially liquid-filled cylindrical tank. The mechanical properties of the container are assumed to change continuously along the thickness according to volume fraction Power-law, Sigmoid or Exponential distribution. The liquid is supposed to be incompressible and in viscid and its velocity potential is formulated ...
متن کاملNumerical Solution for Gate Induced Vibration Due to Under Flow Cavitation
Among the many force s to which hydraulic structures are exposed to, the forces induced by cavitation incident are of typical hydrodynamic unknown forces. The aim of this study is to define these forces as coupled fluid-structure interaction under two dynamic effects. The first dynamic effect which incorporates facilities for dealing with cavitation fluid is based on the appearance and bursting...
متن کاملLow-Lying States of He and Be in Nodal Surface Structure Analysis
The low-lying states of light nuclei He and Be are studied in this letter. With the inherent nodal surface(INS) analysis approach, the quantum numbers and the spatial symmetries of the low-lying states with positive parity and negative parity of the two nuclei are deduced. The obtained energy spectrum structure agrees with experimental data well.

The fermion sign problem is studied in the path integral formalism. The standard picture of Fermi liquids is first critically analyzed, pointing out some of its rather peculiar properties. The insightful work of Ceperley in constructing fermionic path integrals in terms of constrained world-lines is then reviewed. In this representation, the minus signs associated with Fermi-Dirac statistics a...
متن کاملPredicting Deficient Condition Performance of Water Distribution Networks
A water distribution network is subjected to various abnormal conditions such as pipe breaks, pump failures, excessive demands etc. in the design period. Under such conditions, the network may not be able to meet required demands at desired pressures, and becomes deficient. Traditional network analysis assumes nodal demands to be satisfied and available nodal pressures are calculated. However, ...
