With the growth of atypical employment, there is increasing concern about the potential health-damaging effects of unstable employment. This prospective study of Finnish public-sector employees in 1998-2002 examined labor market trajectories and changes in health. At entry, all participants had a fixed-term job contract. Trajectories were measured by exposure to unstable employment during follo...

Multi-hop relay channels use multiple relay stages, each with multiple relay nodes, to facilitate communication between a source and destination. Previously, distributed space-time codes were proposed to maximize the achievable diversity-multiplexing tradeoff, however, they fail to achieve all the points of the optimal diversitymultiplexing tradeoff. In the presence of a low-rate feedback link ...

In a single-hop network with multiple relays, selecting a single node to aid in the transmission between a source and a destination outperforms both traditional orthogonal transmissions and distributed space-time codes. The usage of multiple hops will further improve the wireless communication. This paper presents an energy efficient selection of cooperative nodes with respect to their geograph...

This paper investigates the secure communication in a two-hop cooperative wireless network, where a bufferaided relay is utilized to forward data from the source to destination, and a passive eavesdropper attempts to intercept data transmission from both the source and relay. Depending on the availability of instantaneous channel state information of the source, two cases of transmission mechan...
