The ability to control Poisson's ratio of functional materials has been one the main objectives researchers attempting develop structures efficient from perspective protective, biomedical and soundproofing devices. This task becomes even more challenging at small scales, such as microscale, where possibility mechanical properties is very significant, like in case flexible electronics. In this w...

2. Analysis. A local frame is constructed for each point pi ∈ P based on local (C(pi)) estimation of normal, principal curvatures (λmin, λmax), and principal curvature directions. 3. Sample pruning. A sample for which λmin = λmax is invariant under rotations around its normal, thus a point pair containing such a sample can not define a unique transformation. We reject this kind of samples by us...

BACKGROUND Quality of life instruments provide information that traditional outcome measures used in studies of multiple sclerosis do not. It is unclear if longer, disease-specific instruments provide more useful information than shorter, more general instruments, or whether patients prefer one type to another. METHODS We conducted a cross-sectional study of quality of life in a multiple scle...
