Fertilization is the fundamental process in which two gametes - sperm and oocyte - fuse to generate a zygote that will form a new multicellular organism. In most vertebrates, oocytes await fertilization while arrested at metaphase of meiosis II. This resting state can be stable for many hours and depends on a cytoplasmic activity termed cytostatic factor (CSF). Recently, members of the novel Em...

There is an important difference between a traditional business application and a business process support (BPS) system. A traditional business application is aimed at supporting the old way of doing business but more effectively. A BPS system can be considered as a tool of introducing a new way of organizing work. Moreover, this way is often impossible to introduce without a support system. Th...

Recently, applications in string theory require the knowledge of the UIRs of the conformal superalgebras for D > 6. In these applications most prominent role play the superalgebras osp(1| 2n), cf., e.g., [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]. Initially, the superalgebra osp(1| 32) was put forward for D = 10 [1]. Later it was realized that osp(1| 2n) would fit any dimension, though they are minimal on...

Over the past few years, cloud computing and the growth of global large scale computing systems have led to applications which require data management across multiple datacenters. Initially the models provided single row level transactions with eventual consistency. Although protocols based on these models provide high availability, they are not ideal for applications needing a consistent view ...

The present paper aims to investigate the effects of modularity and the layout of subsystems and parts of a complex system on its maintainability. For this purpose, four objective functions have been considered simultaneously: I) maximizing the level of accordance between system design and optimum modularity design,II) maximizing the level of accessibility and the maintenance space required,III...

For a while, today’s modern people have been struggling with various problems which threaten their health including climate change, water and food scarcities, depression etc. Also, most recently, they faced more complicated- unfamiliar problem, pandemic. And in the future, what kind of different to be cannot predicted. This situation underlines boldly obligation support before then it has lost....

This paper reviews researches on net present value done by researchers in the past 25 years to summarize research results and put forward limitations. Although investment decision guided possesses a long history investors use it widely current financial market, author believes that still has of being discussed studied. After comprehensive review, is found years, focused comparing its advantages...

This paper compares different approaches for computing power products ∏ 1≤i≤k g ei i in commutative groups. We look at the conventional simultaneous exponentiation approach and present an alternative strategy, interleaving exponentiation. Our comparison shows that in general groups, sometimes the conventional method and sometimes interleaving exponentiation is more efficient. In groups where in...

We present a novel new word extraction method from Japanese texts based on expected word frequencies. First, we compute expected word frequencies from Japanese texts using a robust stochastic N-best word segmenter. We then extract new words by filtering out erroneous word hypotheses whose expected word frequencies are lower than the predefined threshold. The method is derived from an approximat...
