In this report we show how to manage a distributed hierarchical structure representing a file system. This structure is optimistically replicated, each user work on his local replica, and updates are sent to other replica. The different replicas eventually observe same view of file systems. At this stage, conflicts between updates are very common. We claim that conflict resolution should rely a...

Abstract Introduction Subjective alertness variations throughout the day can be characterized using two-process model (TPM) of sleep regulation, which combines homeostasis and circadian rhythm to derive a theoretical daytime curve. The TPM has been adopted effect deprivation on memory, misalignment, temperature brain function; however, despite its broad influence, evidence supporting TPM-derive...

We present the temporal and spectral study of blazar PKS 0208-512, using recent flaring activity from November 2019 to May 2020, as detected by Fermi-LAT observatory. The contemporaneous X-ray, optical/UV observations Swift-XRT/UVOT are also used. During state, 2-days binned ${\gamma}$-ray lightcurve shows multiple peaks indicating sub-flares. To understand possible physical mechanisms behind f...
