We study the effective second-harmonic generation (SHG) susceptibility in graded metallic films by invoking the local field effects exactly, and further numerically demonstrate that the graded metallic films can serve as a novel optical material for producing a broad structure in both the linear and SHG response and an enhancement in the SHG signal. ocis: 160.4330, 310.6860, 160.4670, 160.4760.
This study constructs a panel threshold regression model to explore the price impact of foreign institutional herding of firms listed in the Taiwan Stock Exchange during January 2000 to June 2008. Our panel threshold model is constructed to explore the price impact of foreign institutional investors’ herding in the Taiwan stock market after controlling the firm size. By examining the presence o...
Contrary to previous empirical studies that find a linear link between economic conditions and presidential approval, this study argues for and finds a nonlinear relationship. A threshold regression is used to assess potential nonlinear relationships between macroeconomic variables and presidential popularity. A quarterly data analysis for the 1960Q1–2012Q2 time period reveals that domestic fac...
Microfinance is gathering momentum to become a major force in India. The self-help group (SHG) model with bank lending to groups of (often) poor women without collateral has become an accepted part of rural finance. The paper discusses the state of SHG-based microfinance in India. With traditionally loss-making rural banks shifting their portfolio away from the rural poor in the post-reform per...
BACKGROUND Toric intraocular lens (IOL) implantation can be an effective method for correcting corneal astigmatism in patients with vitreoretinal diseases and cataract. Our purpose is to report the outcome of toric IOL implantation in two cases - a patient with scleral-buckle-induced regular corneal astigmatism and a patient with keratoconus following pars plana vitrectomy. As far as we are awa...
AIM To review the rate of retinal detachment after macular hole surgery in patients who received vitrectomy and scleral buckle versus those who had vitrectomy alone. METHODS All patient charts and hospital records were examined for patients who underwent vitrectomy surgery for macular hole between September 1993 and June 1997. A total of 326 patients were identified and all were followed for ...
For Pd thin films, microstructural changes involved during hydrogen cycling provide the information needed to predict and optimize film's mechanical strength. In this paper, a systematic study of morphology, microstructure, texture, stress has been performed on films loading deloading cycles at room temperature. similar morphology were prepared by magnetron sputtering substrates different compl...
in order to evaluate the response of emergence rate of oil seed rape seedlings to temperature, a pot experiment was conducted to assess the relationship between emergence rate of three rape seed cultivars (apetalous flower, rgs003 and syn3) by using a non-linear regression against temperature variation. six models (tooth shape, segmented, beta, curve, quadratic and cubic) were used and the supe...
the ultimate goal of power system operation and planning is to increase power system reliability which enforces interconnected operation of power system. as a result of power system interconnection, the inter-area oscillation under different disturbances may cause power system partial or total blackout. dc-segmentation of interconnected power systems is a solution in which the topology of the n...
