Molecular Oncology, EarlyView.Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

In situ TEM and other dynamic imaging instruments alter the landscape of materials science and engineering. The unique and unprecedented ability to observe the transformation of nanoscale objects as it occurs is unparalleled in comparison to other material characterization methods, and is of tremendous value to material scientists and engineers who ...

Change-points for point processes
2018This chapter studies estimation and testing methods for the intensities of parametric or functional Poisson models, for parametric or nonparametric hazard function under right-censoring and for point processes, with change-points at unknown time thresholds.

Sparse Change-Point VAR models
SSRN Electronic Journal, 2019AbstractChange‐point (CP) VAR models face a dimensionality curse due to the proliferation of parameters that arises when new breaks are detected. We introduce the Sparse CP‐VAR model which determines which parameters truly vary when a break is detected.

The problem is that of testing for a change of the mean in a sequence of independent normal random variables with the same variance. Well-known tests such as likelihood ratio tests, tests based upon cusums of recursive residuals, Pettitt's test and the Chernoff-Zacks' statistic are investigated again through their approximate power.

Smooth random change point models
Statistics in Medicine, 2010AbstractChange point models are used to describe processes over time that show a change in direction. An example of such a process is cognitive ability, where a decline a few years before death is sometimes observed. A broken‐stick model consists of two linear parts and a breakpoint where the two lines intersect. Alternatively, models can be formulated

The main objective of this paper is to survey procedures that one connected with the change point problem and with testing the constancy of regression relationship over a time. We will focus on the case of independent observations. Detailed algorithms are presented for most of the discussed methods.
