The foodborne transmission of Listeria monocytogenes requires physiological adaptation to various conditions, including the cold, osmotic, heat, acid, alkaline, and oxidative stresses, associated with food hygiene, processing, and preservation measures. We review the current knowledge on the molecular stress adaptation responses in L. monocytogenes cells as revealed through transcriptome, prote...

Ubiquitous services have gained increasing attentions in the area of mobile communication aiming to allow service access anywhere, anytime and anyhow while keeping complexity to a minimum for both users and service providers. Ubiquitous environment features a wide range and an increasing number of access devices and network technologies. Context-aware content/service adaptation is deemed necess...

By introducing video-quality adaptation mechanisms into intermediate network equipments using active network technologies, we can provide users with video distribution services taking into account client heterogeneity in terms of available bandwidth, performance of client systems, and user’s preferences about video quality. In this paper, we implement the low-pass filter, a quality adjustment t...

The emerging heterogeneous networking environment will comprise diverse link layer technologies like 3G, WLANs and WPANs. In this context, multimedia applications should be able to cope with packet losses and delays due to congestion, wireless transmission errors and vertical handovers. This paper addresses the functional requirements from an advanced adaptation architecture, which incorporates...

If distributed cognition is to become a general analytic frame, it needs to handle more aspects of cognition than just highly efficient problem solving. It should also handle learning. We identify four classes of distributed learning: induction, repurposing, symbiotic tuning, and mutual adaptation. The four classes of distributed learning fit into a two-dimensional space defined by the stabilit...

A detailed description of x-ray fluorescent holography is given using the formalism of classical electrodynamics. Effects of the wavefront curvature are calculated. It is shown that neglecting these effects might cause large errors especially in the forward direction. The model calculation is compared with experimental data. It is shown that for the model system of NiO the experiment agrees wel...
