Sleep benefits the consolidation of both declarative and nondeclarative memories, however the question if these two memory systems profit from sleep in more or less similar ways is still under debate. Studying the on-line and off-line consolidation of declarative and nondeclarative memory tasks in depressed patients and healthy controls, we here present a clear double dissociation between memor...

Underutilization of computing resources and high power consumption are two primary challenges in the domain of Cloud resource management. This paper deals with these challenges through offline, migration impact-aware, multi-objective dynamic Virtual Machine (VM) consolidation in the context of large-scale virtualized data center environments. The problem is formulated as an NP-hard discrete com...

Consolidation of motor skills after training can occur in a time- or sleep-dependent fashion. Recent studies revealed time-dependent consolidation as a common feature of visuomotor tasks. We have previously shown that anodal transcranial direct current stimulation (tDCS) in combination with repeated motor training benefits consolidation by the induction of offline skill gains in a complex visuo...

The multicast ABR service within ATM is required to efficiently support many data applications including IP multicasting. For point-to-multipoint connections, the branch points of a multicast tree replicate cells traveling from root to leaves and consolidate feedback traveling from leaves to root [1]. The branch-point consolidation is necessary to avoid excessive backward resource management (B...

A new memory is initially labile and becomes stabilized through a process of consolidation, which depends on gene expression. Stable memories, however, can again become labile if reactivated by recall and require another phase of protein synthesis in order to be maintained. This process is known as reconsolidation. The functional significance of the labile phase of reconsolidation is unknown; o...

The acquisition of declarative (i.e., facts) and procedural (i.e., skills) memories may be supported by independent systems. This same organization may exist, after memory acquisition, when memories are processed off-line during consolidation. Alternatively, memory consolidation may be supported by interactive systems. This latter interactive organization predicts interference between declarati...

Memory consolidation is defined temporally based on pharmacological interventions such as inhibitors of mRNA translation (molecular consolidation) or post-acquisition deactivation of specific brain regions (systems level consolidation). However, the relationship between molecular and systems consolidation are poorly understood. Molecular consolidation mechanisms involved in translation initiati...

Sleep supports memory consolidation. Based on studies in mammals, sleep-dependent consolidation has been conceptualized as 'active system consolidation'. During waking, information is encoded into an initial store (hippocampus). During subsequent sleep, some of the newly encoded memories are selected to be reactivated and redistributed toward networks serving as long-term store (e.g., neocortex...

In humans the consolidation of recently learned motor skills is a multi-step process. We previously showed that performance on the finger-tapping task (FTT; i.e. a sequential motor skill) temporarily improves early on, 5-30 min after practice has ended, but not 4 h later. In the absence of any further practice to the task, this early boost in performance was predictive of the performance levels...

Understanding the role of sleep in memory consolidation is an important topic in cognitive neuroscience because it could help us understand the functions of sleep as well as how memory is being consolidated off-line during sleep. Here we review recent studies that focus on the neurophysiological changes that occur during sleep and how these sleep-dependent changes could benefit memory consolida...
