We demonstrate an approach for probing nonlinear electromechanical responses in BiFeO(3) thin film nanocapacitors using half-harmonic band excitation piezoresponse force microscopy (PFM). Nonlinear PFM images of nanocapacitor arrays show clearly visible clusters of capacitors associated with variations of local leakage current through the BiFeO(3) film. Strain spectroscopy measurements and fini...

Pseudomonas syringae pv. actinidiae (Psa) and Pseudomonas syringae pv. actinidifoliorum (Pfm) are closely related pathovars infecting kiwifruit, but Psa is considered one of the most important global pathogens, whereas Pfm is not. In this study of Actinidia deliciosa 'Hayward' responses to the two pathovars, the objective was to test whether differences in plant defense responses mounted agains...

risk management is one of the most important phases of project management and isthe most recently used by many researchers. in this paper, a fuzzy based method wasproposed which identifies different kinds of risks through the project life cycle.then, the project risk magnitude can be obtained in regards to five factors, namely“severity”, “occurrence”, and “not detection” which form fuzzy fmea a...

The high efficiency power management IC (PMIC) with switching device is presented in this paper. PMIC is controlled with PFM control method in order to have high power efficiency at high current level. Dynamic Threshold voltage CMOS (DT-CMOS) with low on-resistance is designed to decrease conduction loss. The threshold voltage of DT-CMOS drops as the gate voltage increase, resulting in a much h...

i ON SYSTEM IDENTIFICATION USING PULSE-FREQUENCY MODULATED SIGNALS Nonperiodic time quantization has proved very useful for the improvement of measurement and control systems. Very often nonperiodic time quantization is connected with pulse frequency modulation (PFM). In the present report some aspects of continuous system identification using PFM signals have been studied. Two possibilities fo...

Hypothesis / aims of study Androgens and anabolic steroids increase muscle mass and strength in general [1]. Due to the characteristics of hyperandrogenism in PCOS, it is plausible that women with PCOS may have increased muscle mass compared with controls [1]. The hyperandrogenism may lead to improve muscle function including pelvic floor muscle (PFM). In a recent study we found that women with...

BACKGROUND No head-to-head trials comparing recombinant factor VIII (rFVIII) products currently exist. This was a matching-adjusted indirect comparison (MAIC) study of efficacy of BAY 81-8973 with antihemophilic factor (recombinant) plasma/albumin-free method (rAHF-PFM) and turoctocog alfa for the prophylaxis of severe hemophilia A. METHODS A systematic literature review was conducted to iden...

In the past, rock slope stability analysis were performed either graphically or using a hand-held calculator, but nowadays there are variety of slope stability analysis which can be used according to the field condition and potential failure mode. In 2-D analysis, effect of convex and concave walls are neglected, however concave slopes are believed to be more stable than straight walls due to t...
