Forcing with Invariant Measures

Logica Universalis
Abstract This paper introduces a model-theoretic generalization of the notion of forcing with random reals, in which forcing gives rise to random generic structures . Specifically, we consider forcing with $$

Uncertainty in NIST force measurements

Journal of Research of the National Institute of Standards and Technology, 2005
This paper focuses upon the uncertainty of force calibration measurements at the National Institute of Standards and Technology (NIST). The uncertainty of the realization of force for the national deadweight force standards at NIST is discussed, as well as the uncertainties associated with NIST's voltage-ratio measuring instruments and with the ...

Measurement of the Casimir-Polder force

Physical Review Letters, 1993
We have studied the deflection of ground-state sodium atoms passing through a micron-sized parallel-plate cavity by measuring the intensity of a sodium atomic beam transmitted through the cavity as a function of cavity plate separation. This experiment provides clear evidence for the existence of the Casimir-Polder force, which is due to modification ...

Direct measurement of thermophoretic forces

Soft Matter, 2015
Thermophoretic forces acting on spherical colloidal particles in confinement are obtained from single particle measurements. This allows to characterize so far inaccessible particle sizes and materials.

Force-displacement measurements in tableting

Journal of Pharmacy and Pharmacology, 1985
Abstract The influence of particle interaction, i.e. friction and bonding, on the net work (NETW) during compaction and on Heckel plots was tested by varying the particle size, the lubrication or the moisture content. The NETW was found to be significantly affected by particle interaction. The yield pressure, calculated from Heckel plots,

Molecular force measurements in desmosomes

, 2018
Desmosomen sind Zellkontakte zwischen benachbarten Zellen und besonders wichtig im Herzen und in der Haut, die starker mechanischer Belastung ausgesetzt sind. Für eine stabile Zelladhäsion sind Desmosomen unerlässlich, aber es war bisher nicht bekannt ob Desmosomen direkt an der Kraftweiterleitung beteiligt sind.
