Implicit surface fitting is a promising approach to finding ridges and valleys in discrete surfaces, but existing techniques are timeconsuming and rely on user-supplied tuning parameters. We use a modified MLS (moving-least-squares) approximation technique to estimate the local differential informat

## Abstract It is shown that the modified stimulated echo sequence, [ΞΈ]~(Β±__x__Β±__y__)~β__t__~1~β[ΞΈ]~(+__x__)~β__t__~2~/2β[2ΞΈ]~(+__x__)~β__t__~2~/2β[ΞΈ]~(+__x__)~β__t__~1~βAcq(Β±__x__ β __y__), denoted as MSTE[2ΞΈ]~__x__~ according to the exciter phase of the 2ΞΈ pulse, is able to perform proton spectr
## Abstract ## Purpose We studied the sonographic appearance of the anterior liver surface using an ultrasound scanner equipped with a 7.5βMHz annularβarray transducer to determine the accuracy of this imaging modality in monitoring the course of chronic liver diseases. ## Methods We prospective
Sterically stabilized biocompatible poly(lactic acid) (PLA) nanospheres were prepared by an o/w emulsion/evaporation technique, using hydrophobically modified dextrans (DexP) as the emulsion stabilizer. Photon correlation spectroscopy, zetametry, and differential scanning calorimetry studies corrobo
