Estimation of univariate regression functions from bounded i.i.d. data is considered. Estimates are deened by minimizing a complexity penalized residual sum of squares over all piecewise polynomials. The integrated squared error of these estimates achieves for piecewise p-smooth regression functions the rate (ln 2 (n)=n) 2p 2p+1 .

The residual stresses that occur in the machined parts after the tools removing are the main cause that determines the springback of the draw parts made from metal sheets. Hence, to investigate this instability phenomenon it must be known the state of residual stresses developed in the part by its machining. But, the experimental investigation of the residual stress distribution in the case of ...

the major problem in material removal process specially grinding is heat generation during the process and thus residual stress on the surface of product. therefore, optimization of high efficiency deep grinding (hedg) process is the main goal of this study in order to reduce heat and residual stress and also increase strength and surface hardness of aisi1045 steel by optimization of the proces...

We provide direct evidence that Bin/Amphiphysin/Rvs (BAR) family members bend the steady state membrane architecture of organelles in intact cells. In response to inducible BAR molecular actuators, organelles exhibit distinct changes to the orientation and degree of their membrane curvature. This rapidly inducible system may offer a mechanism by which to better understand the structure-function...

Determination of protein structure classically results in a single average configuration that takes no account of conformational fluctuation. Dynamics are, however, inherently linked to structure and crucial to our understanding of biological function. In this study we have used analytical descriptions of dynamic averaging of residual dipolar couplings (RDCs) to simultaneously determine the bac...

The thermal conductivity kappa is measured in a series of La2-xSrxCuO4 (0 < or = x < or = 0.22) single crystals down to 90 mK to elucidate the evolution of the residual electronic thermal conductivity kappa(res), which probes the extended quasiparticle states in the d-wave gap. We found that kappa(res)/T grows smoothly, except for a 1/8 anomaly, above x approximately 0.05, and shows no disconti...

In this paper we prove a Hölder and Lipschitz stability estimates of determining the residual stress by a single pair of observations from a part of the lateral boundary or from the whole boundary. These estimates imply first uniqueness results for determination of residual stress from few boundary measurements.
