BACKGROUND Determining real effects on internet dependency is too crucial with unbiased and robust statistical method. MARS is a new non-parametric method in use in the literature for parameter estimations of cause and effect based research. MARS can both obtain legible model curves and make unbiased parametric predictions. METHODS In order to examine the performance of MARS, MARS findings wi...

this process is changing with it. So, what are the clinical hematologists going to do with their microscopes: use them or sell them? Mars van ‘t Veer is a consultant hematologist at Addenbrooke’s University Hospital, Cambridge, UK. Torsten Haferlach works at the MLL Munich Leukemia Laboratory, Germany. Financial and other disclosures provided by the author using the ICMJE (www.icmje.org) Unifor...

The products of the oxidative coupling of phenols are frequently used as synthetic analogues to natural humic substances (HS) for biomedical research. However, their molecular compositions and exact structures remain largely unknown. The objective of this study was to develop a novel approach for the molecular-level analysis of phenolic polymerisates that is capable of inventorying molecular co...

[1] Mars Global Surveyor is providing the first observations of transient eddies in the southern hemisphere of Mars. We derive basic properties of the traveling eddies that appear in midwinter (Ls = 134 –148 ) through analysis of radio occultation measurements at 67 –70 S latitude. The dominant mode has a period of 2 solar days and a zonal wavenumber s = 3. Strong zonal variations in eddy ampli...

The application of “Multivariate Adaptive Regression Splines”(MARS) to the problem of modeling duration of a set of segments used in a text-to-speech system for German is presented. MARS is a technique to estimate general functions of high-dimensional arguments given sparse data. It automatically selects the parameters and the structure of the model based on data available. The result is a mode...

• Heavy oil compounds evolution of cellulose and lignin was investigated with the use FT-ICR-MS. Cellulose-lignin interaction significantly enhanced removal oxygen in heavy components. Three reaction pathways are proposed to explain species under influence interaction. Evolution route components temperature secondary clarified. Cellulose, their mixture were pyrolyzed at 500–700 °C for 60 s 90 i...

Mass spectrometry (MS) can become a potentially useful instrument type for aerosol, droplet and fomite (ADF) contagion surveillance in pandemic outbreaks, such as the ongoing SARS-CoV-2 pandemic. However, this will require development of detection protocols purposing instrumentation situ environmental surveillance. These approaches include: (1) enhancing biomarker by pattern recognition machine...
