a r t i c l e i n f o a b s t r a c t If entitlement to UI benefits must be earned with employment, generous UI is an additional benefit to working, so, by itself, it promotes job creation. If individuals are risk neutral, then there is a UI contribution scheme that eliminates any effect of UI on employment decisions. As with Ricardian Equivalence, this result should be useful to pinpoint the e...

FIG. 1. Quantum metrology strategies. The maps Λφ encode the parameter φ to be estimated. (i) sequential scheme: Λφ acts n times sequentially on N/n input probes ρ (this is an entanglement-free classical scheme) ; (ii) entangled parallel scheme: an entangled state of N probes ρN goes through N maps Λφ in parallel; (iii) passive ancilla scheme: the N probes are also entangled with M noiseless an...

Recently, J.-J. Shen, C.-W. Lin and M.-S. Hwang (Computers & Security, Vol 22, No 7, pp 591-595, 2003) proposed a modified Yang-Shieh scheme to enhance security. They claimed that their modified scheme can withstand the forged login attack and also provide a mutual authentication method to prevent the forged server attack. In this paper, we show that the Shen-Lin-Hwang scheme cannot resist the ...

In 2010, Sood et al [3] proposed a secure dynamic identity based authentication scheme using smart cards. They claimed that their scheme is secure against various attacks. In this paper, we improve their scheme for outsider attack as well as insider attack. To remedy these security flaws, an improved scheme is proposed to withstand these attacks. [1] Introduction With the rapid increasing need ...

This paper presents a user interface (UI) designed for non-visual interaction with a music collection. The UI system can be utilized to navigate a large list of musical items organized in a hierarchical structure, and to generate personal playlists. The interface only relies on stereo audio output and tactile input using a limited small of keys. This interaction scheme enables the use of the UI...
