The implications of the empirical signatures for the positivity of the strangeness magnetic moment μs and the negativity of the the strangeness contribution to the proton spin ∆s on the possible uudss̄ configurations of five quarks in the proton are analyzed. The empirical signs for the values for these two observables can only be obtained in configurations where the uuds subsystem is orbitally ...

In this paper we prove some new fixed point theorems for multivalued mappings on orbitally complete uniform spaces.

Background Orbitally shaken flasks are commonly used at an early stage of bioprocess development with mammalian cells. In contrast to large-scale stirred-tank bioreactors, shaken flasks are usually operated in probe-independent bioprocesses, i.e. without strictly controlling the pH or dissolved oxygen concentration (DO). As a consequence, gas transfer issues are thought to limit the effectivene...

Improving the ability to react to perturbations during daily activities like walking is a key to effective fall prevention training. Quantifying how walking stability changes in response to destabilizing events is critical for assessing how effective gait training interventions are. When small perturbations of increasing amplitude were applied to a dynamic model of walking, the model did not be...

[1] A new chronology of glaciation, spanning the last 780,000 years, is estimated from 21 marine sediment cores using depth as a proxy for time. To avoid biasing this ‘‘depth-derived’’ age estimate, the depth scale is first corrected for the effects of sediment compaction. To provide age uncertainty estimates, the spatial and temporal variability of marine sediment accumulation rates are estima...

The layered manganese oxides LnBaMn1.96Fe0.04Oy (Ln=Y, Gd, Sm, Nd, Pr, La) have been synthesized for y = 5, 5.5 and 6. In oxygen-saturated state (y = 6) they exhibit the charge and orbital order at ambient temperature for Ln=Y, Gd, Sm, but unordered eg-electronic system for Ln=La,Pr,Nd. Fourfould increase of quadrupole splitting was observed in charge and orbitally ordered manganites compared t...
