Optical second harmonic generation (SHG) is used as a noninvasive probe of two-dimensional (2D) ferroelectricity in Langmuir-Blodgett (LB) films of copolymer vinylidene fluoride with trifluorethylene. The surface 2D ferroelectric-paraelectric phase transition in the topmost layer of LB films and a thickness independent (almost 2D) transition in the bulk of these films are observed in temperatur...

We propose a novel type of cascading parametric interaction for generating a nonlinear phase shift in dielectric media with a quadratic nonlinear response based on two-frequency wave mixing of the fundamental and second-harmonic waves. Self-phase modulation of the fundamental wave results from a cascading process consisting of four second-order subprocesses, the direct and reverse subprocesses ...

[1] This study explores the saturation effects in the ionospheric foF2 due to sunspot number R, solar radio noise (10.7 cm) flux F10.7, and solar EUV fluxes. To locate the R, F10.7, or EUV value at which the foF2 values are saturated, a two-segmented regression model is built based on the data of the strictly rise period of the 21st solar cycle recorded by eight ionosonde stations scattering ro...

Predicting protein adsorption from solution to a surface is a perennial problem in biomedicine and related fields. Despite constant attention in the literature, it is not currently possible to predict quantitatively the amount of adsorbed protein given environment, protein and surface parameters. In previous work, we presented the Biomolecular Adsorption Database, an online collection of protei...

Second harmonic generation (SHG) was employed to monitor in situ the potential-induced reconstruction of Au( 111) and Au( 100) electrodes. Rotating the sample by 360” about the surface normal yields for the unreconstructed Au( 1 I1 )-( 1 x 1) SWface the well-known threefold symmetry pattern in the SHG intensity, while Au( lOO)(1 X 1) shows no rotational anisotropy, as expected for C, symmetry. ...

The Maxwell-Wagner type interfacial charging processes were characterized by time-resolved second harmonic generation method (TR-SHG) using three typical organic double-layer devices, i.e., IZO/αNPD/Alq3/Al for OLED and ITO/PI/α-NPD (or pentacene)/Au for MIM elements. Devices with a PI blocking layer represent one-carrier transport case, while the OLED is a typical two-carrier transport device....

We theoretically compare the performance of TPEF and SHG microscopy for membrane potential imaging. We argue that electrochromic TPEF and SHG membrane potential responses are reflections of the same phenomenon, and can be described in a unified manner as resulting from the linear Stark effect. We also show that TPEF and SHG exhibit similar sensitivities in the case of both electrochromic and or...

We introduce STORMED hybrid games (SHG), a generalization of STORMED Hybrid Systems [21], which have natural specifications, allow rich continuous dynamics and admit various properties to be decidable. We solve the control problem for SHG using a reduction to bisimulation on game graphs. This reduction generalizes to a greater family of games, which includes o-minimal hybrid games [5]. We also ...
