Meteoritics &Planetary Science, EarlyView.Abstract The majority of planetary impacts occur at oblique angles. Impact structures on Earth are commonly eroded or buried, rendering the identification of the direction and angle of impact—using methods such as asymmetries in ejecta distribution, surface topographic expression, central uplift structure, and geophysical anomalies—challenging. In this

MathematicsAtherosclerosis, marked by elevated plaque formation, occurs due to stenosis, which narrows the arterial walls and alters the natural flow path. Previous research has shown that the likelihood of high-rupture stenosis can be linked to temperature ...

Testing Uniformity of Stationary Distribution [PDF]
, 2016 A random walk on a directed graph gives a Markov chain on the vertices of the graph. An important question that arises often in the context of Markov chain is whether the uniform distribution on the vertices of the graph is a stationary distribution of ...

Peridynamics with a Cube‐Shaped Neighborhood
PAMM, Volume 26, Issue 1, March 2026.ABSTRACT This paper investigates the effects of cube‐shaped neighborhoods in peridynamic theory as an alternative to the traditional spherical neighborhoods. We examine how different neighborhood geometries influence the behavior of various peridynamic formulations, including bond‐based models, state‐based formulations, and correspondence methods.

3D radiation-hydrodynamics simulations of octahedral spherical hohlraums [PDF]
Matter and Radiation at ExtremesAchieving uniform X-ray irradiation in indirect-drive inertial confinement fusion (ICF) is a key challenge for successful capsule implosion. Spherical hohlraums, particularly those with octahedral laser entrance holes (LEHs), are an alternative to the ...

On disjoint paths in acyclic planar graphs [PDF]
, 2010 We give an algorithm with complexity $O(f(R)^{k^2} k^3 n)$ for the integer multiflow problem on instances $(G,H,r,c)$ with $G$ an acyclic planar digraph and $r+c$ Eulerian.

Variational Modeling of Porosity Waves
PAMM, Volume 26, Issue 1, March 2026.ABSTRACT Mathematical models for finite‐strain poroelasticity in an Eulerian formulation are studied by constructing their energy‐variational structure, which gives rise to a class of saddle‐point problems. This problem is discretized using an incremental time‐stepping scheme and a mixed finite element approach, resulting in a monolithic, structure ...

Inertial migration of rigid particles in shear-thinning fluids under asymmetric wall slip conditions [PDF]
International Journal of Fluid EngineeringThe determination of flow-induced equilibrium positions in pressure-driven flows in microchannels is of great practical importance in particle manipulation. In the computational analysis presented in this paper, the inertial ordering of neutrally buoyant

Quantifying the Influence of Climate on Storm Activity Using Machine Learning
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Midlatitude storms vary due to the slowly evolving climate and the rapidly changing synoptic conditions. While the impact of both factors has been studied extensively, their relative contributions remain poorly quantified. We use 84 years of ERA‐5 reanalysis data and convolutional neural networks to assess the relative importance of seasonal ...
