Immersed cantilever apparatus for mechanics and microscopy

Statistical Mechanics of Amplifying Apparatus

We consider a toy model of a laser with negative temperature amplification. By passing to a new kind of thermodynamic limit, involving the renormalisation of Planck’s constant to zero, we obtain a classically describable measurement apparatus. We introduce a new definition of macroscopic observable which implements Bohr’s insight that the observables of a measurement apparatus are classical in ...

Use of Cantilever Mechanics for Impacted Teeth: Case Series

This paper describes the orthodontic treatment, and the biomechanics of cantilevers for the impaction of permanent teeth in youngs, adolescents, and adults. In these case series, multibracket straightwire fixed appliances, together with cantilever mechanics, were used to treat the impaired occlusion.

Cantilever-Based Optical Interfacial Force Microscopy

An unstructured immersed finite element method for nonlinear solid mechanics

We present an immersed finite element technique for boundary-value and interface problems from nonlinear solid mechanics. Its key features are the implicit representation of domain boundaries and interfaces, the use of Nitsche’s method for the incorporation of boundary conditions, accurate numerical integration based on marching tetrahedrons and cut-element stabilisation by means of extrapolati...

Exploiting cantilever curvature for noise reduction in atomic force microscopy.

Optical beam deflection is a widely used method for detecting the deflection of atomic force microscope (AFM) cantilevers. This paper presents a first order derivation for the angular detection noise density which determines the lower limit for deflection sensing. Surprisingly, the cantilever radius of curvature, commonly not considered, plays a crucial role and can be exploited to decrease ang...
