The mobility prediction problem is defined as guessing a mobile node's next access point as it moves through a wireless network. Those predictions help take proactive measures in order to guarantee a given quality of service. Prediction agents can be divided into two main categories: agents related to a specific terminal (responsible for anticipating its own movements) and those related to an access point (which predict the next access point of all the mobiles connected through it). This paper aims at comparing those two schemes using real traces of a large WiFi network. Several observations are made, such as the difficulties encountered to get a reliable trace of mobiles motion, the unexpectedly small difference between both methods in terms of accuracy, and the inadequacy of commonly admitted hypotheses (such as the different motion behaviours between the week-end and the rest of the week).

See detailThe AP-1 binding sites located in the pol gene intragenic regulatory region of HIV-1 are important for viral replication.

Our laboratory has previously identified an important intragenic region in the human immunodeficiency virus type 1 (HIV-1) genome, whose complete functional unit is composed of the 5103 fragment, the DNaseI-hypersensitive site HS7 and the 5105 fragment. These fragments (5103 and 5105) both exhibit a phorbol 12-myristate 13-acetate (PMA)-inducible enhancer activity on the herpes simplex virus thymidine kinase promoter. Here, we characterized the three previously identified AP-1 binding sites of fragment 5103 by showing the PMA-inducible in vitro binding and in vivo recruitment of c-Fos, JunB and JunD to this fragment located at the end of the pol gene. Functional analyses demonstrated that the intragenic AP-1 binding sites are fully responsible for the PMA-dependent enhancer activity of fragment 5103. Moreover, infection of T-lymphoid Jurkat and promonocytic U937 cells with wild-type and mutant viruses demonstrated that mutations of the intragenic AP-1 sites individually or in combination altered HIV-1 replication. Importantly, mutations of the three intragenic AP-1 sites led to a decreased in vivo recruitment of RNA polymerase II to the viral promoter, strongly supporting that the deleterious effect of these mutations on viral replication occurs, at least partly, at the transcriptional level. Single-round infections of monocyte-derived macrophages confirmed the importance of intragenic AP-1 sites for HIV-1 infectivity. [less ▲]

Intracellular recordings made in vitro from rat midbrain dopamine neurons showed that apamin (100 nM) did not alter the regular spontaneous firing of the neurons, but it increased the occurrence of bursts of action potentials in N-methyl-D-aspartate. Apamin appeared to facilitate burst-firing induced by NMDA because, by blocking an outward calcium-activated potassium current, it increased the depolarizing action of NMDA. [less ▲]

De janvier à mars 1975, nous avons eu l'occasion de séjourner à New-Haven (Etats-Unis) comme "Postdoctoral Research Fellow" à la "School of Forestry and Environmental Studies" de l'Université de Yale. Durant cette période, nous avons vécu en étroite relation avec les enseignants, les chercheurs et les étudiants de la plus vieille école forestière supérieure américaine. Nous avons pensé faire oeuvre utile en essayant de donner un aperçu aussi fidèle que possible des principales caractéristiques d'un enseignement sensiblement distinct, à de nombreux égards, de celui propre à la plupart de nos écoles forestières européennes. Dans ce but, en nous référant tantôt à des aspects généraux (pouvant cependant être assez différents d'une université à l'autre), tantôt à des aspects plus spécifiques à l'Université de Yale, nous envisagerons successivement les points suivants : - la structuration proprement dite des études, - les programmes généraux d'étude, - les grandes lignes du système d'enseignement. Fort de notre "petite" expérience américaine, nous formulerons enfin diverses conclusions et réflexions personnelles. [less ▲]

Since 1982 the gassing of fox earths (the main threat for the badger survival in Belgium) ceased but southern Belgium was also affected by a new outbreak of the rabies epizooty. In such circumstances it appeared interesting to renew the census of occupied badger dens we made previously. The situation we observed in 1985 is nearly the same as in 1981/82. In the middle of the "rabies zone" however badgers settled again in old dens uninhabited for many years because of gassing. This trend is nevertheless counterbalanced dy the disaooearance of badgers from other sites due to snaring, trapping, digging up or plugging the earth's mouths, to human disturbance (namely clear felling) or eventually to rabies itself. The authors finally emphasize the need for a strict enforcement of the new hunting legal dispositions and for the adoption of non detrimental to badgers and effective measures against rabies (f.e. oral vaccination of foxes).
