    “…The analysis of polymorphic variations in the human major histocompatibility complex (MHC) class II genomic region on the short-arm of chromosome 6 is a scientific enquiry to better understand the diversity in population structure and the effects of evolutionary processes such as recombination, mutation, genetic drift, demographic history, and natural selection. …”

    “…Two main mechanisms contribute to the continuous evolution of influenza viruses: accumulation of mutations in the hemagglutinin and neuraminidase genes (antigenic drift) and genetic re-assortments (antigenic shift). …”

    “…In a LAr-TPC, the interacting particles ionize the liquid argon along their tracks. This charge is drifted by a uniform electric field and readout. Additionally, scintillation light is produced, providing a fast signal used as a trigger and also to reconstruct the particle interaction time. …”

    “…The parameters of the demonstrator will be directly scalable and the components mass-produceable. Long drift paths will be assessed on a large scale. As requested by SPSC, we submit a Technical Design Report, in view of a realisation of the facility and an exposure to the charged particle beam before the LHC LS2.…”

    “…The different level of temporal differentiation between the two regions indicates that genetic drift is stronger in Nugruman Escarpment, for as-yet unknown reasons, which may include differences in land management. …”

    “…CONCLUSIONS: Our results suggest that the genetic differentiation at neutral genetic markers among populations of the Baltic cisco complex has evolved (and is maintained) by random genetic drift in isolated populations. However, earlier studies on the Swedish populations combining mitochondrial DNA and microsatellite data indicate that also post-glacial immigration from separate glacial refugia has shaped the present genetic population structure. …”

    “…To model human APOE alleles, this study used APOE targeted replacement (TR) mice on a C57Bl/6 background. To minimize genetic drift, homozygous APOE3 mice were crossed to homozygous APOE2 or homozygous APOE4 mice prior to the study, and the resulting heterozygous progeny crossed further to generate the study mice. …”

    “…Finally, we partially check the consistency of the simulations with experimental data and, as a result, a more accurate value of the local vacuum chamber surface properties is provided, obtaining a new value for the secondary emission yield in a drift space of $\delta_{max}^{0}=1.55$.…”

    “…A new trigger algorithm has been developed to perform the trigger primitive generation in the muon drift tube chambers during HL-LHC. This algorithm profits from the full time resolution provided by the new electronics at trigger level, computing the trigger primitive's time, position, and direction with a resolution comparable to what is reachable with the present offline reconstruction system. …”

    “…Wegen der hohen Luminosit¨at des Beschleunigers und des großen Wirkungs- querschnittes fur Proton-Proton-Kollisionen, herrscht im Myonspektrometer ein erheblicher Untergrund an Photonen und Neutronen. Um das Verhalten der Drift- rohre bei hoher Untergrundz¨ahlrate zu untersuchen, wurde eine Teststrahlmes- sung durchgefuhrt, bei der neben einem hochenergetischen Myonstrahl (100 GeV) auch eine 740 GBq starke γ-Quelle die Kammer beleuchtete. …”

    “…BACKGROUND: To allow time for production, seasonal influenza vaccine target strains must be chosen up to 8 months before the start of the influenza season. Antigenic drift during these months can lead to mismatch between the circulating and vaccine strains, negatively impacting vaccine effectiveness (VE). mRNA vaccines can be produced more quickly than standard vaccines, raising the possibility of delaying influenza vaccine strain selection by up to 3 months, thus potentially improving VE. …”
