The ability to cryopreserve and successfully recover cell lines has been critical to the conservation of all cell lines, especially the preservation of pristine early-stage cultures and the preparation of well-characterized cell banks. Indeed, the systematic storage and establishment of cryopreserved banks of cells for the stem cell research community is fundamental to the promotion of standard...

We propose a new method for designing nonuniform lapped transforms. The proposed method provides a simple yet effective way of designing lapped transforms with nonuniform frequency resolution and good time localization. This method is a generalization of an approach proposed by Princen, where the nonuniform filter bank is obtained by joining uniform cosine-modulated filter banks using transitio...

We explore the phenomenon and economics of private equity investments by bank-affiliated groups. Between 1983 and 2009, bank-affiliated private equity groups accounted for over a quarter of all private equity investments. Banks’ involvement increases during peaks of the private equity cycles. In particular, deals done by bank-affiliated groups are financed at significantly better terms than oth...

Wavelet packet decompositions based on tree structured 2-channel filter banks with conjugate quadrature filters (CQF) have recently found many applications in the area of audio coding. Their time-frequency tiling is dual to that of timevarying modulated lapped transforms (MLT). In this paper we present a new orthonormal wavelet packet basis, which is constructed by frequency-varying MLT. These ...

The Russian banking sector experienced considerable turmoil in the late 1990s, especially around the Russian banking crisis in 1998. The question is what types of banks are vulnerable to shocks and whether or not bank-specific characteristics can be used to predict vulnerability to failures. In this study we employ a parametric logit model and a nonparametric trait recognition approach to predi...

Traditional monetary theory has largely ignored the role of bank equity. Bank-centred accounts of how monetary policy affects the real economy usually focus on the role of reserves and reserve requirements in determining the volume of demand deposits and, in the case of the bank lending channel, bank loans. As Benjamin Friedman (1991) observed, “Traditionally, most economists have regarded the ...

although the word of “money laundering” isn’t very old in world literature, but attempted money laundering has a long history a long side with trade and commerce, as it always has been told. money laundering is a process that the incomes of criminal acts enter to the economic cycle and will purify dirty income. therefore, we can say launderers are actually committed two offenses, primaril...

This paper examines the causal e¤ects of bank size on banks’ survival, asset quality, and leverage. Two forces drive these e¤ects: increasing returns to scale derived from banks’expertise; and competition. The …rst enables bigger banks to survive competition better, have higher asset-quality, and be more leveraged. It drives banks into a race for expansion. This race toughens competition betwee...

This paper investigates whether Japanese banks followed herd behavior in lending in local financial markets during 1980—1999. By using loan data from Japanese banks, arranged by geographical area, we find leader-follower relationships between lending behavior of different types of banks. Specifically, herding is mostly caused by local banks. Local banks follow major banks in urban cities, while...

Banks play important roles in promoting national development. In order to provide efficient services and to perform their statutory roles effectively, banks are required to comply with established standards. In Nigeria, the Statement of Accounting Standards (SAS), Companies and Allied Matters Act (CAMA) and the Central Bank of Nigeria’s directives and regulations provide guidelines to banks in ...
