Churn prediction methods are widely used in Customer Relationship Management and have proven to be valuable for retaining customers. To obtain a high predictive performance, recent studies rely on increasingly complex machine learning methods, such as ensemble or hybrid models. However, the more complex a model is, the more difficult it becomes to understand how decisions are actually made. Pre...

Palliative treatment of bone metastases: analysis of biological effects of MR guided Focused Ultrasound (MRgFUS) versus External Beam Radiation Therapy (EBRT). A randomized comparative trial using Functional Diffusion Maps as molecular activity indicator Michele Anzidei, Alessandro Napoli, Giulia Brachetti, Maurizio Del Monte, Daniel De Olivera, Fabrizio Andrani, Carola Palla, Luca Bertaccini, ...

introduction: emergency department is one of the most important hospital wards that offers emergency services to unstable patients 24 hours a day, 7 days a week. however, the way the services are offered reflects the general status of the hospital since patients with the most serious problems frequently refer to the emergency department. emergency department waiting time is one of the indices u...

the objective of this study is to measure the city of tehran’s environmental quality in 2006 (the last census year). primarily, with a comparative analysis of a variety of urban sustainability indicator models, a collection of 54 indicators have been chosen and categorized as indicators of increase or decrease in urban environmental quality in the form of a simple mathematical model. based o...

We report a combined molecular dynamics (MD) and ab initio simulation study of the ultrafast broadband ultraviolet (UV) stimulated resonance Raman (SRR) spectra of the Trp-cage mini protein. Characteristic two dimensional (2D) SRR features of various folding states are identified. Structural fluctuations erode the cross peaks and the correlation between diagonal peaks is a good indicator of the...

The rollover of electron density, a common indicator for the onset volumetric recombination, was observed in hydrogen plasma, first time DT-ALPHA. Electron density and temperature were measured near plasma production region secondary gas feeding position with various conditions regarding amount gas. A at position, whereas remained nearly constant. This behavior indicates an enhancement molecula...
