Consistent insight is presented into the atomistic origin and temperature (T) dependence of the redshift of Raman optical modes in nanostructures from the perspective of surface bond unsaturation and the bond-order-length-strength (BOLS) correlation [Sun et al., Phys Rev B 72, 134301 (2005)]. It turns out that: (1) the size-induced redshift of Raman optical modes results from the effect of bond...

stress-induced cardiomyopathy or takotsubo cardiomyopathy is a recently increasing diagnosed disease manifested by transient apical or mid left ventricular dilation and dysfunction. this sign is similar to acute myocardial infarction but without significant coronary artery stenosis. there are important and essential differences between takotsubo cardiomyopathy and acute myocardial infarction in...

Human embryonic stem cells (hESCs) have the potential to form any cell type in the body, making them attractive cell sources in drug screening, regenerative medicine, disease and developmental processes modeling. However, not all hESC lines have the equal potency to generate desired cell types in vitro. Significant variations have been observed for the differentiation efficiency of various huma...

This paper reviews the recent progress in the analysis and applications of the symmetry-related electromagnetic properties of transmission lines loaded with symmetric configurations of resonant elements. It will be shown that the transmission characteristics of these reactively loaded lines can be controlled by the relative orientation between the line and the resonant elements. Two main types ...

purpose : to report a patient with retained broken probe tip in the false passage site after nasolacrimal duct (nld) probing case report : a 18-month-baby with epiphora and a nontender mass in the site of lacrimal sac was visited in clinic. she had a history of probing six months ago by another ophthalmologist. the probing was repeated successfully but the mass size didn’t change. the mass was ...

The existence of a frozen mode in periodic serpentine waveguide with broken longitudinal symmetry is demonstrated numerically. associated stationary inflection point (SIP) the Bloch dispersion relation, where three eigenmodes collapse on each other, as it an exceptional order three. regime characterized by vanishing group velocity and enhanced field amplitude, which can be very attractive vario...
