Gravitational forces acting on in situ bank material act in concert with hydraulic forces at the bank toe to determine rates of bank erosion. The interaction of these forces control streambank mechanics. Hydraulic forces exerted by flowing water on in situ bank-toe material and failed cohesive material at the bank toe are often sufficient to entrain materials at relatively frequent flows and to...

To provide more insights into the responses of the soil seed bank and vegetation to human disturbance intensity, we selected four land use types, including: native grassland (no human disturbance), abandoned artificial grassland (light human disturbance), artificial grassland (moderate human disturbance), and farmland (severe human disturbance) in a semi-arid climate of northern China. The spec...

Increasing attention in invasion biology is being paid to measuring and understanding the impacts of invasive species. For plant invasions, however, the impact of invasion on soil seed bank communities has been under-studied. At six sites in southern Germany, we investigated whether areas invaded by Solidago gigantea and Solidago canadensis experienced a reduction in seed bank species richness,...

A growing number of commentators advocate enhancing the role of market discipline in the banking industry. They argue that if private sector stakeholders can discourage excessive risk-taking and encourage safe banking practices through the pricing of bank securities, then the extensive regulatory framework currently in place may be unnecessarily burdensome. In the wake of recent studies conclud...

A bank affiliated with a multi-bank holding company (MBHC) is significantly safer than either a stand-alone bank or a bank affiliated with a one-bank holding company. Not only does affiliation reduce the probability of future financial distress, but distressed affiliated banks are more likely to receive capital injections and recover more quickly than other banks. Interestingly, the effect of a...

extended distribution of digicash has commercial, socio-economic as well as political effects. from the economic viewpoint, the most crucial effect of digicash use extension takes place on money supply, monetary policies and central bank. because digicash is capable of being replaced by bank notes and the coins, it is possible that digicash gradually takes the place of the central bank money an...

A new filter bank approach for speaker recognition front-end is proposed. The conventional mel-scaled filter bank is replaced with a speaker-discriminative filter bank. Filter bank is selected from a library in adaptive basis, based on the broad phoneme class of the input frame. Each phoneme class is associated with its own filter bank. Each filter bank is designed in a way that emphasizes disc...

We study the genealogical structure of samples from a population for which any given generation is made up of direct descendents from several previous generations. These occur in nature when there are seed banks or egg banks allowing an individual to leave offspring several generations in the future. We show how this temporal structure in the reproduction mechanism causes a decrease in the coal...
