Ensemble All Time-Scale Decomposition Method and Its Application in Bevel Gear Fault Diagnosis
SensorsAll time-scale decomposition (ATD) is a non-parametric adaptive signal decomposition method, which relies on zero-crossing points and extreme points to jointly construct the baseline, achieving the suppression of modal mixing caused by the proximity of ...

Mixed-Mode and Mixed-Device Surveys
, 2017 Online surveys are one of the most prominent data collection methods in Europe and the USA. Not only are they fast and cheap, data quality in well-designed online surveys is high, especially when sensitive questions are asked. Disadvantages are the threat of undercoverage, as not everyone has Internet access, and high nonresponse.

Tracking text in mixed-mode documents [PDF]
Proceedings of the ACM conference on Document processing systems - DOCPROCS '88, 1988 This paper describes a method for extracting arbitrarily oriented text in documents containing both text and graphics. The technique presented is inspired by the tracking algorithms frequently found in raster to vector conversion systems. By identifying text components in the document, reducing the resolution of the image by the size of the characters,

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Evidence for electron-phonon interaction in Fe$_{1-x}$M$_{x}$Sb$_{2}$ (M=Co, Cr) single crystals
, 2011 We have measured polarized Raman scattering spectra of the Fe$_{1-x}$Co$_{x}$Sb$_{2}$ and Fe$_{1-x}$Cr$_{x}$Sb$_{2}$ (0$\leq x\leq $0.5) single crystals in the temperature range between 15 K and 300 K.
