Time delay for an abstract quantum scattering process [PDF]
, 2011 In this short review paper, we discuss the concept of time delay for an abstract quantum scattering system. Its definition in terms of sojourn times is explained as well as its identity with the so-called Eisenbud-Wigner time delay. Necessary and natural

Demonstration of negative group delays in a simple electronic circuit
, 2002 We present a simple electronic circuit which produces negative group delays for base-band pulses. When a band-limited pulse is applied as the input, a forwarded pulse appears at the output.

Power-Law Negative Group Delay Filters
ElectronicsA study of the behavior of the power-law negative group delay filters, accompanied by a comparison with their integer-order counterparts, is performed in this work. Employing a curve-fitting based approximation technique, the resulting integer-order rational transfer function is versatile in the sense that it has the same form independent of the order ...

Investor Panic, IMF Actions, and Emerging Stock Market Returns and Volatility [PDF]
In this paper, we examine the reaction of stock market returns and volatility in a diverse group of six emerging markets to a set of IMF events. In particular, we test within a panel framework whether there was an "investor panic" causing a significant ...

Vulnerability of Microfinance to Strategic Default and Covariate Shocks:Evidence from Pakistan [PDF]
This paper investigates the repayment behavior of microfinance borrowers in Pakistan using a unique dataset of about 45,000 installments/repayments covering 2,945 microfinance borrower households over the period 1998-2007. In early 2005, the microfinance

Methodology of elementary negative group delay active topologies identification
IET Circuits, Devices & Systems, 2013 This work introduces a fundamental methodology enabling to identify the elementary negative group delay (NGD) topologies using transistors. These circuits are particularly beneficial compared to the other existing NGD topologies, with its flexibility to operate in ultra wideband (UWB), to compensate losses and potentially integrable. The basic families

Delaying Trains of Short Light Pulses in WGM Resonators [PDF]
Suitably configured whispering-gallery-mode (WGM) optical resonators have been proposed as delay lines for trains of short light pulses. Until now, it has been common practice to implement an optical delay line as a coiled long optical fiber, which is ...
