We show that the second knee in the cosmic ray spectrum (i.e. the steepening occurring at E ≃ 4× 10 eV) could be related to drift effects affecting the heaviest nuclear component, the iron group nuclei, in a scenario in which the knee at 3×10 eV indicates the onset of drift effects in the lighter proton component. We also study the anisotropies resulting from diffusion and drift currents in the...

The task in the computer security domain of anomaly detection is to characterize the behaviors of a computer user (the "valid’, or "normal’ user) so that unusual occurrences can be detected by comparison of the current input stream to the valid user’s profile. This task requires an online leaming system that can respond to concept drift and handle discrete non-metric time sequence data. We pres...

Assimilatory phonetic drift in L1 has been shown to occur in early second language learners when separate L2 categories have not been established. The direction and likelihood of drift is affected by degree of L1:L2 difference [2], and the need to maintain L1 distinctions [10]. We assessed the impact of explicit L2 phonetic training on L1:L2 interaction when novel L2 sounds could lead to a more...

Wind controls the formation and development of sand dunes. Therefore, understanding wind regimes is necessary in dune research. In this study, we combined data from 2017 to 2019 at four meteorological stations (Cherigele Wuertabulage lake basins, Yikeri Sumujilin on top dunes) hinterland Badain Jaran Desert China, with high resolution Google Earth images analyze correlation between energy envir...

the gravimetric method is one of the most effective ways for the detection of subsurface structures such as tunnels, faulting, mineral deposits with the required density difference, especially in areas with rough topography and tectonized formations. it is possible to provide a more suitable model for better interpretation of the gravity anomaly. inverse modeling of gravity data is the most eff...

there has been too much of a one-way flow drift down a river of evidence. researchers from rich countries have produced the primary evidence which they proceed to summarise within reviews. these summaries have directed care worldwide. however, things are changing and the river of evidence can flow in the other direction. the care of women with eclampsia has been changed or refined throughout th...

We studied the drift of electron spins under an applied dc electric field in single layer graphene spin valves in a field-effect transport geometry at room temperature. In the metallic conduction regime (n approximately 3.5 x 10(16) m(-2)), for dc fields of about +/- 70 kV/m applied between the spin injector and spin detector, the spin valve signals are increased or decreased, depending on the ...

A complex interaction of controllable and uncontrollable factors is involved in aerial application of crop production and protection materials. Although it is difficult to completely characterize spray deposition and drift, these important factors can be estimated with appropriate sampling protocol and analysis. Application height is an important variable influencing off-target spray drift, but...

Activities with high spinal loads should be avoided by patients with back problems. Awareness about these activities and knowledge of the associated loads are important for the proper design and pre-clinical testing of spinal implants. The loads on an instrumented vertebral body replacement have been telemetrically measured for approximately 1000 combinations of activities and parameters in 5 p...
