Abstract Piezoelectricity in native bones has been well recognized as the key factor bone regeneration. Thus, bio-piezoelectric materials have gained substantial attention repairing damaged by mimicking tissue’s electrical microenvironment (EM). However, traditional manufacturing strategies still encounter limitations creating personalized scaffolds, hindering their clinical applications. Three...

Phase-shifting interferometry with a genetic algorithm is proposed. The correction of unknown phase-shifting error is an important task in general phase-shifting interferometry. Since phase-shifting errors generate twin image noise in a reconstructed image, we can reduce the phase-shifting errors indirectly by trying to eliminate the twin-image noise in the reconstructed image. By Zernike polyn...

competition is against monopoly and intellectual property creates monopoly for intellectual property owner. this article had been paid cooperation between apparently contradictory policies. exhaustion, parallel imports, compulsory license, intellectual property exploitation contract that coincide with competition are methods of cooperation between intellectual property and competition law. comp...

BACKGROUND Uganda has a severe health worker shortage and a high demand for health care services. This study aimed to assess the policy and programmatic implications of task shifting in Uganda. METHODS This was a qualitative, descriptive study through 34 key informant interviews and eight (8) focus group discussions, with participants from various levels of the health system. RESULTS Policy...

Thermal energy storage (TES) system has been introduced as a practical facility for shifting load from peak hours to off-peak hours. Because of different energy consumption during day and night, peak and off peak period is created on load curve. Ice storage technology which is a kind of TES system, is implemented in different points of the world with the purpose of solving load shifting problem...

This paper describes the application of an important tool which can capture shifting information from pilots’ visual attention data. In order to investigate the shifting information, the shifting state space is defined by visual tracking, visual interference and visual dormancy. Using this analysis, the movement of pilots’ visual attention can be completely measured. The results that the foreca...

Introduction: This study aimed to investigate and compare the executive functions of students with depression, anxiety, and stress symptoms with those functions in healthy ones. Methods: This study was a comparative and non-clinical analysis. The study population comprised all students of Shahid Beheshti University, Tehran, Iran. A total of 448 students were recruited using convenience sam...

In this paper a method for digitally recording four quarter-reference-wave-holograms (by CCD) in a Mach-Zehnder interferometer setup, and reconstructing the object wave-front by numerical method is presented. The terms of direct transmission, auto-correlation and conjugate wave in the four wave reconstruction are cancelled out and only one original object wave is left after overlapping. Reconst...

Neuropsychological tests that require shifting an attentional set, such as the Wisconsin Card Sorting Test, are sensitive to frontal lobe damage. Although little information is available for humans, an animal experiment suggested that different regions of the prefrontal cortex may contribute to set shifting behavior at different levels of processing. Behavioral studies also suggest that set shi...

There is increasing recognition that set-shifting, a form of cognitive control, is mediated by different neural structures. However, these regions have not yet been carefully identified as many studies do not account for the influence of component processes (e.g., motor speed). We investigated gray matter correlates of set-shifting while controlling for component processes. Using the Design Flu...
