The quantization scheme between double enhanced charge phase-slip (ECPS) qubits is given. In this system, there exist quantum entanglement phenomenona. The entanglement characteristic is discussed by employing the concurrence. An interesting conclusion is obtained, i.e., if one desire to change the entanglement between two ECPS qubits, the mutual inductance should be considered first, but it is also a good choice to tune symmetric and asymmetric combination of two gate voltages.

Quantum disentanglement refers to the transformation of entangled quantum system into disentangled system via some physical processes. In this paper, we search for quantum disentangling operator for the mesoscopic two-loop [Formula: see text] circuit with mutual inductance [Formula: see text]. It is this mutual inductance that causes quantum entanglement. By virtue of the method of integration within ordered product (IWOP) of operators, we find the disentangling operator and deduce the energy level (characteristic frequency). The quantum noise expression of squeezed vacuum state is also derived based on which we see that the large number of quantum entanglement engendered by the mutual inductance is, the more quantum noise produces in the mesoscopic circuit.

Studies of the effects of hydrogen environments on the deformation and fracture of fcc, bcc and hep metals and alloys have been carried out in a TEM environmental cell. The initial experiments were performed in the environmental cell of the HVEM facility at Argonne National Laboratory. More recently, a dedicated environmental cell facility has been constructed at the University of Illinois using a JEOL 4000EX and has been used for these studies. In the present paper we will describe the general design features of the JEOL environmental cell and some of the observations we have made on hydrogen effects on deformation and fracture.The JEOL environmental cell is designed to operate at 400 keV and below; in part because of the available accelerating voltage of the microscope and in part because the damage threshold of most materials is below 400 keV. The gas pressure at which chromatic aberration due to electron scattering from the gas molecules becomes excessive does not increase rapidly with with accelerating voltage making 400 keV a good choice from that point of view as well. A series of apertures were placed above and below the cell to control the pressures in various parts of the column.

Abstract. White people often experience unpleasant emotions in response to learning about White privilege ( Phillips & Lowery, 2015 ; Pinterits, Poteat, & Spanierman, 2009 ). Two studies (total N = 1,310) examined how race attitudes relate to White people’s desires to avoid or learn information about White privilege. White participants completed measures of their race attitudes, desire to change White privilege, and their desire to avoid learning information about White privilege. Study 1 showed that participants who preferred their racial in-group reported less desire to change White privilege and greater desire to avoid learning information about White privilege. Inconsistent with expectations, Study 2 showed that participants who anticipated negative affective responses to learning about White privilege reported greater desire to change White privilege.

Desire To Change

Anger is a basic human emotion that has a force for constructive or destructive ends. Its expression in any circumstance can be a trigger for a desire to change a prevailing situation. In all cases, anger is a fundamental component of art. This study examines the use of anger in Osborne’s Look Back in Anger and Osofisan’s The Chattering and the Song. Osborne and Osofisan are two writers who are very anxious to change their societies through their art. In spite of differences in their origin (Osborne was a Briton while Osofisan is a Nigerian), they wrote at a time of certain social and political upheavals in their countries. They also share similar concerns and attitudes towards art. My focus in this paper is on the early plays of Osborne and Osofisan where anger is strongest and where their artistic triumph is most poignant. Working within the formalist approach, the paper reveals that in Osborne and Osofisan, extreme anger is both material and style and is what marks their art out. The reification by the intellect provides a potent instrument for investigating society. Anger becomes the point of departure for their art, it is not mere hysterics but a cerebral one and it is the motivating force for their writings.
