GLUL Confers Perivascular Cancer‐Associated Fibroblasts With Pro‐Angiogenic Capacity to Promote Glioma Progression

open access: yesAdvanced Science, EarlyView.
Schematic illustration of the proposed model. Primary CAFs are isolated from fresh human GBM specimens according to established protocols. GLUL is essential for pro‐angiogenic capacity of CAFs through its impact on the PI3K/AKT pathway. GLUL enhances the pro‐angiogenic capacity of CAFs, driving aberrant tumor vasculature that fuels tumor growth ...

Autopolyploidization‐Induced Chromatin Remodeling Regulates Leaf Size Variation in Brassica rapa

open access: yesAdvanced Science, EarlyView.
This study demonstrates that monoploid, diploid, and autotetraploid Brassica rapa lines derived from the same genome exhibit distinct leaf morphology. Ploidy changes remodel chromatin accessibility and histone modifications to regulate gene expression, while key transcription factors BrGRF13 and BrARF11 control leaf size and polarity, driving ...

Decision Trees

open access: yesEncyclopedia of Database Systems, 2009
Linear regressors from X = R to Y = R have a limited expressive power, because they fit K affine functions to the training set. Functions that are more complex than that are approximated poorly.

Trees and decisions [PDF]

open access: possibleEconomic Theory, 2005
The traditional model of sequential decision making, for instance, in extensive form games, is a tree. Most texts define a tree as a connected directed graph without loops and a distinguished node, called the root. But an abstract graph is not a domain for decision theory.

Decision Trees

2023
Neural networks are a way to mimic the working of a human brain. Decision trees refer to the decision support structure that uses a tree to make decisions and draw all possible consequences. Decision trees are a way to display conditional control statements.

Oncology Decision Tree

Collegian, 2000
Financial cutbacks and budgetary constraints continue to be a part of government policy, and impact deeply on many aspects of daily life in Australia in the late 90s. Health care is not immune from these measures, and nurses and other allied health professionals are having to manage increasingly complex patient care with less funding and resources ...

Decision Tree

2023
In this chapter, we explore the concept of decision trees, prioritizing accessibility by minimizing abstract mathematical theories. We examine a concrete numerical example using a small dataset to predict the suitability of playing tennis based on weather conditions, guiding readers through the process step-by-step. Moreover, we provide sample codes
