Chaotic terrains are broad regions on Mars characterized by the disruption of basaltic bedrock into polygonal blocks separated deep fractures. To date, proposed genetic scenarios often involve occurrence subsurface ice or liquid H2O. Nevertheless, similar features also occur within some craters Moon, namely floor-fractured (FFCs), where water reservoirs not present. We propose a new formation m...

Colorectal polyps are precursor lesions of colorectal cancer; hence, early detection and dysplasia grading essential for determining cancer risk, the possibility developing subsequent polyps, follow-up recommendations. The significant contribution this study is development an enhanced deep-learning model called Fast Fourier Convolutional ResNet (FFC-ResNet) to classify grades polyps. It based o...

In this paper, a feedback compensator (FBC) and Feedforward (FFC) are proposed to construct novel compensated peak current mode control pulse width modulation (CPC-PWM) for primary-side controlled flyback converters. Using the FBC, PWM duty cycle of an abnormal operating converter would be descended limit output reducing power dissipation. FFC, effect delay time reduce over-flow increasing accu...

Traditional orthopedic casting strategies used in the treatment of fractured limbs, such as fiberglass and plaster-based tapes, suffer from several drawbacks, including technically challenging molding for application, occurrence skin complications, requirement a potentially hazardous oscillatory saw removal, which is frightening pediatric patients. This work presents design evaluation foam-fabr...

background: households’ financial protection against health payments and expenditures and equity in utilization of health care services are of the most important tasks of governments. this study aims to measuring equity in household’s health care payments according to fairness in financial contribution (ffc) and kakwani indices in tehran-iran, 2013. methods: this cross-sectional study was condu...

The direction sensitivity of relay cells in the cat's dorsal lateral geniculate (LGNd) was measured using sinusoidal grating stimuli before and during local bicuculline administration. One hundred and twenty-eight LGNd relay cells were recorded in laminae A and A1, of which 44 relay cells (34%) were found to be sensitive to direction of stimulus movement. The direction-sensitive LGNd relay cell...

This study aims to measuring equity in household's health care payments according to fairness in financial contribution (FFC) and Kakwani indices in Tehran-Iran, 2013.

Fair clustering aims to partition a dataset while mitigating bias in the original dataset. Developing fair algorithms has gained increasing attention from machine learning community. In this paper, we propose k-means algorithm, first (FFC), which consists of an initialization stage, relaxation and improvement stage. is employed cluster each group. Then combination step refinement are applied en...

Aquatic ecological problems caused by pharmaceutical and personal care products (PPCPs) are increasingly becoming an issue of concern. In this study, the seasonal spatial occurrence environmental risk 20 PPCPs were studied at 19 sampling points in surface waters Lianjiang River basin (southern China); its watershed is about 10,100 km2. Sample preparation was performed using solid-phase extracti...
