Structured Energy Conversion in Kelvin‐Helmholtz Instability
Abstract We present quantitative investigations of the energy conversion pathways—electromagnetic ϵEM $\left({{\epsilon}}^{EM}\right)$, fluid flow ϵf $\left({{\epsilon}}^{f}\right)$, and particle thermal ϵth $\left({{\epsilon}}^{th}\right)$ energies—within the Kelvin‐Helmholtz instability (KHI) observed by the Magnetospheric Multiscale mission. We find

Long‐Wavelength Infrared InAs/GaSb T2SLs on Silicon: A Review
This review summarises growth techniques for GaSb/GaAs/Si wafers, compares different growth techniques for GaSb buffer on GaAs wafers, LWIR InAs/GaSb T2SLs on InAs, GaSb, and GaAs wafers and proposes the buffer design for the growth of LWIR InAs/GaSb T2SLs on Si wafers, shown in the schematic.

The separatrix electron density is an important parameter for core-edge scenario integration in tokamak devices, as it influences plasma confinement, divertor detachment and disruption avoidance.

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing
Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can

Basins of Attraction and Escape in Pendulum‐Type Potentials with Quadratic Air Drag
ABSTRACT Quadratic air drag is a common dissipative mechanism at moderate to high velocities, yet in nonlinear one‐degree‐of‐freedom systems, it typically blocks closed‐form solutions and energy‐based phase‐plane partitions. We study the autonomous class ẍ+α(x)|ẋ|ẋ+β(x)sgn(ẋ)+V′(x)=0,$$\begin{equation*} \ddot{x}+\alpha (x)\,|\dot{x}|\,\dot{x}+\beta

The Role of Magmatic Styles in Planetary Thermal Evolution Models
Abstract Previous studies that investigated the effects of magmatism on the interior dynamics, in particular for Earth‐sized planets, suggest that magmatism leads to more efficient mantle cooling. However, the extent to which different magmatic styles influence the thermal evolution of planets, and in particular smaller rocky bodies, has not yet been ...

A Physics‐Based Frequency‐Temperature Seismic Anelastic Attenuation Model for Planetary Ice Shells
Abstract Intrinsic attenuation in planetary ices remains poorly constrained at seismic frequencies and low temperatures, limiting quantitative predictions of wave propagation in icy moons. Existing models typically rely on constant‐Q, or power‐law formulations that lack microphysical grounding and fail to capture the strong temperature sensitivity of ...

Highly Enriched and Heterogeneous Mantle Signals Recorded in Mantle Pyroxenite Veins
Abstract The Earth's mantle is inherently heterogeneous, reflecting ongoing mantle depletion and crustal recycling driven by plate tectonics. Radiogenic isotopes in oceanic basalts are commonly used to characterize mantle reservoirs, but the full chemical diversity of mantle‐derived melts may be obscured by magma mixing during melt transport and ...

Abstract The origin of the compositional dichotomy between high‐Ti and low‐Ti basalts in continental flood basalt provinces remains debated. Most existing studies attribute this dichotomy directly to variations in primitive magma composition to circumvent the complexities of significant evolutionary processes, such as multiphase fractional ...
