Lattice mismatch strain induced by HfO2 warps and reshapes the valence subbands, and reduces the hole effective masses. The maximum value of hole density is observed near the top comers of the channel. The hole density is decreased by the lattice mismatch strain. The phonon scattering rate is degraded by strain, which results in higher hole mobility.展开更多

When we add a modulated periodic externa/force to the system, the phase transition can also be found with a critical value δe. Due to coupling between the force and the intrinsic fluctuation of the velocity on shells in GOY model, the stability of the system has been changed, which results in the variation of the critical value. For proper intensity and period of the force, δe is unequal to δ0. The critical value is a nonlinear function of amplitude of the force, and the fluctuation of the velocity can resonate with the external force for certain period Te.展开更多

It occurs less frequently on the lower limbs where other etiological factors are involved. Objective: To determine the epidemiological aspects of cutaneous squamous cell carcinoma of the lower limbs in Goinia. Methodology: Forty-three cases of cutaneous squamous cell carcinoma of the lower limbs from the Cancer Registry of the Population Base of Gois, for the period between 1995 and 1999, were included in the study. Results: Among the cases of cutaneous squamous cell carcinoma registered in this 5-year interval, 43 (4.6%) represented cases affecting the lower limbs. Of these individuals, seven (16.3%)were male and 36 (83.7%)-female (P < 0.001). Those in the age group of 60 years and above represented 90.7%of the cases (P < 0.001). None of the patients had metastasis. Conclusion: Cutaneous squamous cell carcinomas on the lower limbs are more frequently seen in women older than 60 years of age, and they rarely metastasize.展开更多
