The Virial Expansion of the Hydrogen Equation of State in Comparison to PIMC Simulations: The Quasiparticle Concept, IPD, and Ionization Degree

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

A novel algebraic technique for adjacency matrices of some derived graphs

open access: yesMathematical and Computer Modelling of Dynamical Systems
Graph energy has been the main concern of spectral graph theory in the last five decades. The classical graph energy is the sum of the absolute values of the eigenvalues of the adjacency matrix. In many research papers, different versions of graph energy

A novel construction approach for the pore structure model principally focuses on the controllable roundness of rock particles

open access: yesDeep Underground Science and Engineering, EarlyView.
Particle rounding effects comparison of different methods: (a), (b), and (c) are the rounding results using the B‐spline curve method with different R; (d), (e), and (f) are the results of vertex rounding substitution method with different rounding radii.

Investigation of the failure characteristics of fissure tunnels under dynamic and static combinations

open access: yesDeep Underground Science and Engineering, EarlyView.
This article aims to investigate the dynamic fracture response of fractured tunnel models under zero geological stress through physical experiments and numerical simulations. It further simulates the dynamic fracture characteristics of fractured tunnel models under geological stress ranging from 0 to 2.5 MPa using the numerical software AUTODYN ...

Robinow syndrome DVL1 variants disrupt morphogenesis and appendage formation in a Drosophila disease model

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Robinow syndrome is a rare developmental syndrome caused by variants in genes in Wnt signaling pathways. We previously showed that expression of patient variants in Dishevelled 1 (DVL1) in Drosophila and chicken models disrupts the balance of canonical and non‐canonical Wnt signaling.

Developing a macroecology for human‐altered ecosystems

open access: yesEcography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

Distinct thalamic functional connectivity and volume patterns across focal epilepsies in children: A multimodal neuroimaging study

open access: yesEpilepsia, EarlyView.
Abstract Objective The thalamus is a key hub in seizure propagation, and its nuclei are emerging targets for neuromodulation. However, the contributions of individual nuclei to epileptic networks remain unclear, particularly in children, who are less studied than adults.

Packing subdivisions into regular graphs

open access: yes
We show that, for any graph $F$ and $η>0$, there exists a $d_0=d_0(F,η)$ such that every $n$-vertex $d$-regular graph with $d \geq d_0$ has a collection of vertex-disjoint $F$-subdivisions covering at least $(1-η)n$ vertices. This verifies a conjecture of Verstraëte from 2002 and improves a recent result of Letzter, Methuku and Sudakov which ...

Open diffusion magnetic resonance imaging and connectivity data for epilepsy and surgery: The IDEAS II release

open access: yesEpilepsia, EarlyView.
Abstract Objective Epileptic seizures are generated in cerebral networks that propagate ictal and interictal activity. The structure of cerebral networks underpinning epileptic activity can be inferred from diffusion‐weighted magnetic resonance imaging (DWI).
