Distributed space-time coding for two-way wireless relay networks [PDF]

, 2009
In this paper, we consider distributed space-time coding for two-way wireless relay networks, where communication between two terminals is assisted by relay nodes. Relaying protocols using two, three, and four time slots are proposed. The protocols using

Rejuvenated Amorphous Alloys: Processing Methods, Microstructures and Mechanical Properties

Advanced Science, EarlyView.
Three rejuvenation methods – mechanical and thermal rejuvenation, and other rejuvenation routes such as ultrasonic processing – can be used to modify structures of glassy alloys, especially atomic clusters, and therefore enhances plasticity and activates work‐hardening behaviors.

Asymptotic Capacity of Large Fading Relay Networks with Random Node Failures

, 2010
To understand the network response to large-scale physical attacks, we investigate the asymptotic capacity of a half-duplex fading relay network with random node failures when the number of relays $N$ is infinitely large.

Space-Time Communication Protocols for N-way Relay Networks [PDF]

, 2008
We address communication protocols for N-way relay networks with M antennas at the relay and a single antenna at the N source terminals. In particular, amplify-and-forward (AF), decode-and-forward (DF), and compress-and-forward (CF) strategies are ...

Advancing Energy Materials by In Situ Atomic Scale Methods

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Sustainability Orientation and Sustainable Innovation: Can Organisational Resilience Clarify the Missing Link?

Business Strategy and the Environment, EarlyView.
ABSTRACT Although firms that integrate a sustainability orientation (SO) may experience a significant improvement in their resource efficiency, many, particularly small‐ and medium‐sized enterprises (SMEs), still struggle with the complexities of incorporating sustainability into their business models.
