Clearing electrodes have been successfully used to remove the ion from the vacuum chamber in many electron accelerators, especially in electron synchrotron light source. Electron cloud caused beam instabilities and vacuum pressure rise are becoming more and more important with the increasing beam intensity in recent years. In this paper we have explored the mechanism to clear the electron cloud...

Bulletin | J U N E Q Ua r t E r 2012 I have not spoken publicly on payments system matters for some time, but it would be hard to find a better moment and a more appropriate event to take up the issue once more. This symposium of course marks 20 years of the Australian Payments Clearing Association (APCA) , which was set up as a vehicle to coordinate decision-making in relation to clearing and ...

General Equilibrium and the Emergence of (Non) Market Clearing Trading Institutions We consider a pure exchange economy, where for each good several trading institutions are available, only one of which is market-clearing. The other feasible trading institutions lead to rationing. To learn on which trading institutions to coordinate, traders follow behavioural rules of thumb that are based on t...

The recent credit crisis has heightened the awareness of credit risk among financial markets’ regulators and participants. However, despite the public discussion on centralized processing systems for the off-exchange traded (Over-The-Counter, OTC) transactions no research has been conducted on the factors that could explain their adoption among market participants. With this study, an attempt i...

In recent years, advances in laser microscopy and endogenous fluorescent tagging techniques have led to the development of many tissue-clearing strategies, which render tissues optically transparent, allowing large blocks of unsectioned tissue to be visualized in three dimensions (3D). CLARITY (Clear Lipidexchanged Acrylamide-hybridized Rigid Imaging/ Immunostaining/In situ hybridization-compat...
