Reconstruction of critical coalbed methane logs with principal component regression model: A case study

Energy Exploration & Exploitation, 2020
Wireline logging plays a critical role in coalbed methane exploration. However, the lack of crucial log data, such as neutron and sonic logs, makes coalbed methane exploration difficult.

A large‐scale retrospective study in metastatic breast cancer patients using circulating tumour DNA and machine learning to predict treatment outcome and progression‐free survival

Molecular Oncology, EarlyView.
There is an unmet need in metastatic breast cancer patients to monitor therapy response in real time. In this study, we show how a noninvasive and affordable strategy based on sequencing of plasma samples with longitudinal tracking of tumour fraction paired with a statistical model provides valuable information on treatment response in advance of the ...

Chemoresistome mapping in individual breast cancer patients unravels diversity in dynamic transcriptional adaptation

Molecular Oncology, EarlyView.
This study used longitudinal transcriptomics and gene‐pattern classification to uncover patient‐specific mechanisms of chemotherapy resistance in breast cancer. Findings reveal preexisting drug‐tolerant states in primary tumors and diverse gene rewiring patterns across patients, converging on a few dysregulated functional modules. Despite receiving the

Log-log Convergence for Noisy Optimization

, 2014
We consider noisy optimization problems, without the as-sumption of variance vanishing in the neighborhood of the optimum. We show mathematically that simple rules with exponential number of re-samplings lead to a log-log convergence rate. In particular, in this case the log of the distance to the optimum is linear on the log of the num-ber of ...

Expression and DNA methylation of 20S proteasome subunits as prognostic and resistance markers in cancer

Molecular Oncology, EarlyView.
Comprehensive analysis of genomic mutations, gene expression, DNA methylation, and pathway analysis of TCGA data was carried out to define cancer types in which proteasome subunits expression is associated with worse survival. Albeit the effect of specific proteasome subunits on cellular function, the main role of the proteasome is better evaluated ...

Flume Experiments With Refractive‐Index Matched Sediment Revealing the Impact of Two In‐Line Channel‐Spanning Logs on Hyporheic Exchange

Water Resources Research
In‐channel wood, a critical component of forested rivers, has the capacity to enhance hyporheic flow. This process facilitates the continuous exchange of gases, solutes, and nutrients across the sediment‐water interface, regulating pollutant transport ...

Determination of conversion factors for pine and spruce logs in stacks

Leśne Prace Badawcze, 2019
The aim of this article was to determine the conversion factors for stacked pine and spruce logs with a length of 3–6 m. To this end, we measured stacks and their logs of a total of 3322.12 steres of pine logs and 1468.46 steres of spruce logs.

Created substrates do not fully mimic natural substrates in restoration: the occurrence of polypores on spruce logs

Silva Fennica, 2014
Many protected areas have been under intensive forest management prior to protection and thus lack natural ecosystem structures and dynamics. Dead wood is a key structure in forests harboring hundreds of threatened species. We investigated the ecological
