Normrank Correlations for Testing Associations and for Use in Latent Variable Models
Open Education StudiesPearson’s correlation is widely used to test for an association between two variables and also forms the basis of several multivariate statistical procedures including many latent variable models. Spearman’s ρ\rho is a popular alternative.

Provable Sparse Tensor Decomposition
, 2016 We propose a novel sparse tensor decomposition method, namely Tensor Truncated Power (TTP) method, that incorporates variable selection into the estimation of decomposition components. The sparsity is achieved via an efficient truncation step embedded in

Molecular Oncology, EarlyView.In patients treated with atezolizumab as a part of the MyPathway (NCT02091141) trial, pre‐treatment ctDNA tumor fraction at high levels was associated with poor outcomes (radiographic response, progression‐free survival, and overall survival) but better sensitivity for blood tumor mutational burden (bTMB).

Molecular Oncology, EarlyView.C–C chemokine receptor type 9 (CCR9) is an immune checkpoint in pancreatic ductal adenocarcinoma (PDAC). Novel anti‐CCR9 antibody SRB2 was evaluated in combination with cytotoxic chemotherapy in PDAC cells, patient‐derived organoids, patient‐derived xenografts, and humanized mouse models.

Macroscopic thermodynamics of equilibrium characterized by power-law canonical distributions
, 2000 Macroscopic thermodynamics of equilibrium is constructed for systems obeying power-law canonical distributions. With this, the connection between macroscopic thermodynamics and microscopic statistical thermodynamics is generalized.

Unraveling LINE‐1 retrotransposition in head and neck squamous cell carcinoma
Molecular Oncology, EarlyView.The novel RetroTest method allows the detection of L1 activation in clinical samples with low DNA input, providing global L1 activity and the identification of the L1 source element. We applied RetroTest to a real‐world cohort of HNSCC patients where we reported an early L1 activation, with more than 60% of T1 patients showing L1 activity.

Theory and practice of clinical trials in oncology and hematology
Онкогематология, 2016 In the era of evidence-based medicine the main reason for the implementation of new treatment methods are the results of clinical trials. However, clinical trials is a separate area of knowledge, which is often little known to clinicians, that does not ...

EMT‐associated bias in the Parsortix® system observed with pancreatic cancer cell lines
Molecular Oncology, EarlyView.The Parsortix® system was tested for CTC enrichment using pancreatic cancer cell lines with different EMT phenotypes. Spike‐in experiments showed lower recovery of mesenchymal‐like cells. This was confirmed with an EMT‐inducible breast cancer cell line.

Self-organization of structures and networks from merging and small-scale fluctuations
, 2004 We discuss merging-and-creation as a self-organizing process for scale-free topologies in networks. Three power-law classes characterized by the power-law exponents 3/2, 2 and 5/2 are identified and the process is generalized to networks.
