Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

open access: yesPopulation Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

Practical Comparison of Results of Statistic Regression Analysis and Neural Network Regression Analysis

open access: yesLittera Scripta, 2016
There are many discussions and arguments about accuracy of the results of statistic regression analysis and neural network regression analysis among experts. Of course all of them look for the best method usable in practice.

The driving mechanisms for human settlement and ecological environment in the upper minjiang watershed, China

open access: yesFrontiers in Environmental Science, 2023
The Chinese urbanization process is undergoing rapid development and intensification. There is, however, little awareness of spatial development in rural areas, particularly in watersheds that are relatively backward. Consequently, human settlements have

Goodbye flat lymphoma biology

open access: yesFEBS Letters, EarlyView.
Three‐dimensional (3D) biological systems have become key tools in lymphoma research, offering reliable in vitro and ex vivo platforms to explore pathogenesis and support precision medicine. This review highlights current 3D non‐Hodgkin lymphoma models, detailing their features, advantages, and limitations, and provides a broad perspective on future ...

Genomic regression analysis of coordinated expression

open access: yesNature Communications, 2017
Somatic copy number alterations (SCNA) can confound gene co-expression analysis in cancers. Here the authors develop a method to remove the effects of SCNA in co-expression analysis, improving the analysis of network rewiring in cancer, and provide a ...

Regression trees to identify combinations of farming practices that achieve the best overall intrinsic quality of milk

open access: yesJournal of Dairy Science, 2023
: Many studies over the last 30 years have shown the effects of farming practices on milk compounds. Combinations of practices may have antagonistic or synergistic effects on milk compounds, but these combination effects remain underinvestigated ...

From lactation to malignancy: A comparison between healthy and cancerous breast gland at single‐cell resolution reveals new issues for tumorigenesis

open access: yesFEBS Letters, EarlyView.
Single‐cell RNA sequencing reveals an opposite role of SLPI in basal tumors based on metastatic spread, along with shared activation of specific regulons in cancer cells and mature luminal lactocytes, as well as downregulation of MALAT1 and NEAT1 in the latter.

Preponderantly increasing/decreasing data in regression analysis

open access: yesCroatian Operational Research Review, 2016
For the given data (wI, xI, yI ), i = 1, . . . , n, and the given model function f (x; θ), where θ is a vector of unknown parameters, the goal of regression analysis is to obtain estimator θ∗ of the unknown parameters θ such that the vector of residuals ...

How to Define and Test an Indirect Moderation Model: The Missing Link in Regression-Based Path Models

open access: yesMethodology, 2022
Two of the most important extensions of the basic regression model are moderated effects (due to interactions) and mediated effects (i.e. indirect effects). Combinations of these effects may also be present.
