Modelling and Differential Quantification of Electric Cell-Substrate Impedance Sensing Growth Curves
Sensors, 2021 Measurement of cell surface coverage has become a common technique for the assessment of growth behavior of cells. As an indirect measurement method, this can be accomplished by monitoring changes in electrode impedance, which constitutes the basis of ...

Analgesic prescribing trends in a national sample of older veterans with osteoarthritis: 2012-2017 [PDF]
, 2019 Few investigations examine patterns of opioid and nonopioid analgesic prescribing and concurrent pain intensity ratings before and after institution of safer prescribing programs such as the October 2013 Veterans Health Administration system-wide Opioid ...

Consistent model selection in segmented line regression [PDF]
Journal of Statistical Planning and Inference, 2016 The Schwarz criterion or Bayes Information Criterion (BIC) is often used to select a model dimension, and some variations of the BIC have been proposed in the context of change-point problems. In this paper, we consider a segmented line regression model with an unknown number of change-points and study asymptotic properties of Schwarz type criteria in ...

Applied Sciences, 2023 This paper aims to propose a statistical model to assess pubertal growth spurt using the ratio of the anterior height projection to the posterior (Vba) of the fourth cervical vertebra body (C4) on cephalograms and to calculate the residual proportion of ...

Nuclei segmentation via sparsity constrained convolutional regression [PDF]
2015 IEEE 12th International Symposium on Biomedical Imaging (ISBI), 2015 Automated profiling of nuclear architecture, in histology sections, can potentially help predict the clinical outcomes. However, the task is challenging as a result of nuclear pleomorphism and cellular states (e.g., cell fate, cell cycle), which are compounded by the batch effect (e.g., variations in fixation and staining). Present methods, for nuclear

Asset allocation, cross-class correlation and the structure of property returns [PDF]
, 1999 Practical applications of portfolio optimisation tend to proceed on a “top down” basis where funds are allocated first at asset class level (between, say, bonds, cash, equities and real estate) and then, progressively, at sub-class level (within property

A Dual Model of Open Source License Growth [PDF]
, 2013 Every open source project needs to decide on an open source license. This decision is of high economic relevance: Just which license is the best one to help the project grow and attract a community?

Modeling association between DNA copy number and gene expression with constrained piecewise linear regression splines [PDF]
, 2013 DNA copy number and mRNA expression are widely used data types in cancer studies, which combined provide more insight than separately. Whereas in existing literature the form of the relationship between these two types of markers is fixed a priori, in ...

Interactive Natural Image Segmentation via Spline Regression [PDF]
IEEE Transactions on Image Processing, 2009 This paper presents an interactive algorithm for segmentation of natural images. The task is formulated as a problem of spline regression, in which the spline is derived in Sobolev space and has a form of a combination of linear and Green's functions. Besides its nonlinear representation capability, one advantage of this spline in usage is that, once ...
