Malignant astrocytic glioma: genetics, biology, and paths to treatment.

Genes & Development, 2007
Malignant astrocytic gliomas such as glioblastoma are the most common and lethal intracranial tumors. These cancers exhibit a relentless malignant progression characterized by widespread invasion throughout the brain, resistance to traditional and newer ...

Showing the path to path dependence: the habitual path [PDF]

European Political Science Review, 2014
This article investigates the conceptual and theoretical implications of the logic of habit for the path-dependence approach. In the existing literature, we see two different logics of action associated with two distinct models of path dependence: the logic of consequences (instrumental rationality) is linked with utilitarian paths (i.e.

Note on the problem of partially link disjoint paths [PDF]

, 2003
This paper discusses the problem of partially link disjoint paths in communication networks. The problem is situated in between the well-known shortest path generation and the synthesis of two disjoint paths.

A Note on Path Domination

Discussiones Mathematicae Graph Theory, 2016
We study domination between different types of walks connecting two non-adjacent vertices u and v of a graph (shortest paths, induced paths, paths, tolled walks).

A Path-Based Partial Information Decomposition

Entropy, 2020
Based on the conceptual basis of information theory, we propose a novel mutual information measure—‘path-based mutual information’. This information measure results from the representation of a set of random variables as a probabilistic graphical model ...

Band structure diagram paths based on crystallography [PDF]

, 2016
Systematic and automatic calculations of the electronic band structure are a crucial component of computationally-driven high-throughput materials screening.

On the Lettericity of Paths

Australas. J Comb., 2020
Verifying a conjecture of Petkov{š}ec, we prove that the lettericity of an n-vertex path is precisely $\left\lfloor \frac{n+4}{3}\right\rfloor$.

Inducibility of directed paths [PDF]

, 2020
A long standing open problem in extremal graph theory is to describe all graphs that maximize the number of induced copies of a path on four vertices.

The Saturation Number for the Length of Degree Monotone Paths

Discussiones Mathematicae Graph Theory, 2015
A degree monotone path in a graph G is a path P such that the sequence of degrees of the vertices in the order in which they appear on P is monotonic. The length (number of vertices) of the longest degree monotone path in G is denoted by mp(G).

From the Crossing Numbers of K₅ + P_n and K₅ + C_n to the Crossing Numbers of W_m + S_n and W_m + W_n

Axioms
The crossing number of a graph is a significant measure that indicates the complexity of the graph and the difficulty of visualizing it. In this paper, we examine the crossing numbers of join products involving the complete graph K5 with discrete graphs,
