    In this paper, the effect of bilayer graphene on sensitivity of surface plasmon resonance (SPR) biosensor is numerically presented. It shows that the zero reflection at the resonance angle occurred by choosing proper thickness for gold and graphene layers. This research analyzes light reflection in angular modulation with a fixed wavelength (?=633 nm) of incident light regarding to variation in thickness of gold layer underlying bilayer graphene. In comparison to the conventional SPR sensors, graphene based sensor gives a larger local change in the refractive index near the sensor surface. The light reflection coupled into a SPR mode propagating along a gold-graphene layer is calculated and compared to a conventional SPR sensor with varied gold thicknesses

    Background: Using effective interventions to reduce incompatibility among couples can play a role in preventing divorce in the family. The present study aimed to compare the effectiveness of emotion-focused couple therapy (EFCT) and acceptance and commitment therapy (ACT) on forgiveness in incompatible couples. Methods: The present research is a quasi-experimental study that was done on couples referred to a family therapy clinic in Torbat-e-Jam City. Here, 24 incompatible couples were selected through purposive methods and randomly replaced in three groups. The first and second groups (8 couples in each group) received emotion-focused couples and acceptance and commitment therapies, respectively, and the third group as control (8 couples) did not receive any intervention during the study period. All three groups were evaluated before and after the intervention with a standard questionnaire of Bagarozi forgiveness (2001). Data were analyzed through SPSS software version 20 and covariance analysis. Results: The findings revealed that both therapies of EFCT and ACT had a meaningful effect on forgiveness (P < 0.001, F = 41.73, and P = 0.031, F = 5.13; respectively); while the results indicated that the two groups under intervention have no significant difference in terms of effectiveness on the variable of forgiveness (P=0.63, F=0.23). Conclusion: According to the results and effectiveness of the two therapy groups, it is recommended to use a combination of approaches according to the therapeutic goals

    Let GG be a locally compact group and HH be a compact subgroup of GG. Using a general criterion established by Neufang in \cite{Neuf} we show that the Banach algebra L1(G/H)L^1(G/H) is Arens irregular for a large class of locally compact groups. DOI: 10.1017/S000497271200012
