De Vrijer has presented a proof of the finite developments theorem which, in addition to showing that all developments are finite, gives an effective reduction strategy computing longest developments as well as a simple formula computing their length. We show that by applying a rather simple and intuitive principle of duality to de Vrijer’s approach one arrives at a proof that some developments...

In this paper, based on the concept of green supply chain management, we construct a two-level game model consisting an upstream manufacturer and downstream retailer, where retailer is leader follower. addition, in invests carbon-neutral technology innovations that reduce production costs, lower carbon emissions, increase market demand for their products. Based model, optimal equilibrium outcom...

Fitts' (1954) classic theorem asserts that the movement time (MT) of voluntary reaches is determined by amplitude and width requirements (i.e., index of difficulty: ID). Actions associated with equivalent IDs should elicit equivalent MTs regardless of the amplitude and/ or width requirements. However, contemporary research has reported that amplitude-based contributions to IDs yield larger incr...

Predation is a fundamental interaction between species, yet it is unclear what escape strategies are effective for prey survival. Classical theory proposes that prey should either escape in a direction that conforms to a performance optimum or that is random and therefore unpredictable. Here, we show that larval zebrafish (Danio rerio) instead use a mixed strategy that may be either random or d...

Despite great advances in the analysis of time-varying images, implementing or searching for correct and robust algorithms is still challenging and elusive. This paper examines some of the reasons why the motion solution to a problem is sensitive to small changes in the image data. We will discuss whether these sources of difficulty are inherent, predictable, or avoidable. We will also present ...

The present study aimed at determining whether (1) children were able to interrupt a strategy execution to switch and choose another better strategy, and (2) their ability to switch strategy within-item improved with age. Third, fifth, and seventh graders performed a computational estimation task in which they had to provide the better estimates to two-digit addition problems (e.g., 32 + 54) wh...

background: ˝radioadaptive response˝ is well-documented phenomenon appeared in low dose ionizing radiation received in vitro and in vivo. occupational exposure has always been a great concern for radiation workers therefore this study was performed to study radioadaptive response in terms of residual dna double strand breaks as an endpoint in peripheral blood leukocytes of occupationally expose...

in this article differential transformation method (dtms) has been used to solve neutral functional-differential equations with proportional delays. the method can simply be applied to many linear and nonlinear problems and is capable of reducing the size of computational work while still providing the series solution with fast convergence rate. exact solutions can also be obtained from the kno...
