Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Intermediate-mass-ratio Inspirals with General Dynamical Friction in Dark Matter Minispikes

The Astrophysical Journal
Intermediate-mass-ratio inspirals (IMRIs) may be surrounded by dark matter (DM) minispikes. The dynamical friction from these DM minispike structures can affect the dynamics and the gravitational-wave (GW) emission of the IMRIs. We analyze the effects of

The quasi-static approximation of the spring-slider motion [PDF]

Nonlinear Processes in Geophysics, 1996
The spring-slider is a simple dynamical system consisting in a massive block sliding with friction and pulled through a spring at a given velocity.

Nonlinear Vibration Characteristics of a Flexible Blade with Friction Damping due to Tip-Rub

Shock and Vibration, 2011
An approximate approach is proposed in this paper for analyzing the two-dimensional friction contact problem so as to compute the dynamic response of a structure constrained by friction interfaces due to tip-rub.

Distinguishing Dark Matter Cusps from Cores Using Globular Clusters

The Astrophysical Journal, 2023
Globular clusters (GCs) provide valuable insight into the properties of their host galaxies’ dark matter halos. Using N -body simulations incorporating semianalytic dynamical friction and GC−GC merger prescriptions, we study the evolution of GC radial ...

Consequences of Triaxiality for Gravitational Wave Recoil of black holes [PDF]

, 2006
Coalescing binary black holes experience a ``kick'' due to anisotropic emission of gravitational waves with an amplitude as great as 200$ km/s. We examine the orbital evolution of black holes that have been kicked from the centers of triaxial galaxies ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Dynamical friction and measurements of the splashback radius in galaxy clusters

The Open Journal of Astrophysics
The splashback radius is one popular method of constraining the size of galaxy clusters, often measured through the logarithmic derivative of the galaxy number density profile.

Effects of dynamical evolution on the distribution of substructures

, 2004
We develop a semi-analytical model that determines the evolution of the mass, position and internal structure of dark matter substructures orbiting in dark matter haloes. We apply this model to the case of the Milky Way.
