Regression Based Expected Shortfall Backtesting

, 2019
This paper introduces novel backtests for the risk measure Expected Shortfall (ES) following the testing idea of Mincer and Zarnowitz (1969). Estimating a regression framework for the ES stand-alone is infeasible, and thus, our tests are based on a joint

Survival probability in diffractive Higgs production in high density QCD

, 2007
In this paper, the contribution of hard processes described by the BFKL pomeron exchange, is taken into account by calculating the first enhanced diagram. The survival probability is estimated, using the ratio of the first enhanced diagram and the single

Comparing data quality between online panel and intercept samples

Methodological Innovations, 2016
Although some research effort has been devoted to the comparison of probability- and nonprobability-based Web surveys, different types of nonprobability-based samples have not been thoroughly examined.

Security-Reliability Analysis of Noma-Based Multi-Hop Relay Networks in Presence of an Active Eavesdropper with Imperfect Eavesdropping CSI

Advances in Electrical and Electronic Engineering, 2017
In this paper, we evaluate system performances of a multi-hop relay protocol with presence of an active eavesdropper. In the proposed protocol, a source attempts to transmit its data to a destination with assistance of multiple intermediate relays.

Intercept Probability of Underlay Uplink CRNs with Multi-Eavesdroppers

2019 IEEE 30th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2019
The present contribution investigates the physical layer security in a cognitive radio network (CRN). To this end, we consider an underlay uplink CRN consisting of multiple secondary sources, a single-antenna secondary base station, and multiple eavesdroppers. In addition, we assume that the secondary sources transmit their data sequentially and that a

Intercept-Resend Attack on SARG04 Protocol: An Extended Work

Polytechnic Journal, 2020
In this paper, intercept/resend eavesdropper attack over SARG04 quantum key distribution protocol is investigated by bounding the information of an eavesdropper; then, the attack has been analyzed.

Likelihood Inference In Parallel Systems Regression Models With Censored Data [PDF]

, 1997
The work in this thesis is concerned with the investigation of the finite sample performance of asymptotic inference procedures based on the likelihood function when applied to the regression model based on parallel systems with censored data.

Experimental investigation of quantum key distribution with position and momentum of photon pairs

, 2005
We investigate the utility of Einstein-Podolsky-Rosen correlations of the position and momentum of photon pairs from parametric down-conversion in the implementation of a secure quantum key distribution protocol.
