This study Formal Shoes examines the effect of transaction frequency on profit and cash flow risk for firms that periodically purchase inputs, continuously transform inputs into outputs, and periodically sell output.Soybean-processing profit and cash flows are computed for unhedged, direct-hedged, and risk-minimizing-hedged processing with up to 52

Public health emergencies, such as the COVID-19 pandemic, elucidate the strengths, weaknesses, and significant gaps in infrastructure, compatibility and consistency in communication systems, as well as the quality of collaborative relationships, and provider and workforce capacity.They also expose longstanding patterns of mistrust in the government

Radar is one of remote sensing technology which utilizes active electromagnetic energy and are able to provide information about the characteristics of forest stand.This study utilized JERS-1 and ERS-1 radar images to analyze the relationship between the radar backscatter and forest stand characteristics such as Diameter Breast Height (DBH), basal

Skin necrosis is the most common complication in total auricular reconstruction, which is mainly induced by vascular compromise and local stress concentration of the overlying skin.Previous studies generally emphasized the increase in the skin flap blood supply, while few reports considered the mechanical factors.However, skin injury is inevitable

n this study, a batch least square estimator that utilizes optical observation data Oils is developed and utilized to determine geostationary orbits (GEO).Through numerical simulations, the effects of error sources, such as clock errors, measurement noise, and the a priori state error, are analyzed.The actual optical tracking data of a GEO satellit
