A New Definition of a Collision Zone For a Geometrical Model For Ship-Ship Collision Probability Estimation [PDF]

TransNav, 2011
In this paper, a study on a newly developed geometrical model for ship-ship collisions probabil-ity estimation is conducted. Most of the models that are used for ship-ship collision consider a collision be-tween two ships a physical contact between them.

Estimating Ordered Probabilities

The Annals of Mathematical Statistics, 1963
Let $X_i, Y_i i = 1, 2, \cdots n$ be mutually independent binomial random variables with $P\{X_i = 1\} = p_1, P\{Y_i = 1\} = p_2$. Let $\bar X_n = (1/n) \sum^n_{i = 1} X_i$ and $\bar Y_n = (1/n) \sum^n_{i = 1} Y_i$. We wish to estimate the parameter $p = (p_1, p_2)$. If the parameter space is $\Omega = \{p \mid 0 \leqq p_1 \leqq 1, 0 \leqq p_2 \leqq 1\}

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

Molecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Maximum probability O-D matrix estimation in large-sized networks [PDF]

Iranian Journal of Numerical Analysis and Optimization, 2020
We propose a maximum probability model to estimate the origin-destination trip matrix in the networks, where the observed traffic counts of links and the target origin-destination trip demands are independent discrete random variables with known ...

Differential expression of cancer‐related genes supports prediction of poor response to first‐line treatments in T‐ALL pediatric patients with high minimal residual disease

Molecular Oncology, EarlyView.
In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...
