The aim of this study was to investigate the effect of Er:YAG laser irradiation on human dentin surface using X-ray photoelectron spectroscopy (XPS). 10 human dentin disks were prepared from extracted human molars for XPS analysis. These specimens were divided into two groups of five: a control group and group that were irradiated by an Er:YAG laser beam (100 mJ, 1Hz). All specimens were analyz...

In this paper we describe game-independent strategies, capable of learning explanation patterns (XPs) for evaluation of any basic game pattern. A basic game pattern is defined as a minimal configuration of a small number of pieces and squares which describes only one salient game feature. Each basic pattern can be evaluated by a suitable XP. We have developed five gameindependent strategies (re...

PURPOSE We present the 1-year results of the GOLIATH prospective randomized controlled trial comparing transurethral resection of the prostate to GreenLight XPS for the treatment of men with nonneurogenic lower urinary tract symptoms due to prostate enlargement. The updated results at 1 year show that transurethral resection of the prostate and GreenLight XPS remain equivalent, and confirm the ...

The characterization of chemically modified sensors and biosensors is commonly performed by cyclic voltammetry and electron microscopies, which allow verifying electrode mechanisms and surface morphologies. Among other techniques, X-ray photoelectron spectroscopy (XPS) plays a unique role in giving access to qualitative, quantitative/semi-quantitative and speciation information concerning the s...

The aim of this document is to compare the results obtained with package xps to the results obtained with Affymetrix Power Tools (APT version apt-1.10.2). For this purpose the Exon Array Data Set ”Tissue Mixture” will be used, which can be downloaded from the Affymetrix web-site for expression arrays ”Human Genome U133 Plus 2.0”, ”Human Gene 1.0 ST” and ”Human Exon 1.0 ST”, respectively. First,...

X-ray photoelectron spectroscopy (XPS) has achieved maturity as an analytical technique in the materials community, however made apparent by recent reviews highlighting it's misuse, it is a practice which often misunderstood.

UV-irradiation (172 nm) induced changes of PDMS surfaces were investigated with X-ray photoelectron spectroscopy (XPS) and spectroscopic ellipsometry (SE). Both methods indicate the modification of the PDMS to a silicalike surface (SiO2). These conclusions could be drawn from the elemental composition determined by XPS and the binding energy shifts in the XPS spectra of the Si 2p and O 1s level...
