A “Valley” in Heliospheric Energetic Particle Intensities and Implications for a New Horizons Encounter with the Solar Wind Termination Shock

The Astrophysical Journal
We analyze ∼40–200 keV energetic particle observations from the Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI) on board the New Horizons (NH) spacecraft from 2007 to 2024 and compare them with similar measurements from the Low ...

Injection Process of Pickup Ion Acceleration at an Oblique Heliospheric Termination Shock

The Astrophysical Journal Letters
The injection process of pickup ion acceleration at a heliospheric termination shock is investigated. Using two-dimensional fully kinetic particle-in-cell simulation, accelerated pickup ions are self-consistently reproduced by tracking long time ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

Advanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Proving Termination of Input-Consuming Logic Programs [PDF]

, 1999
A class of predicates is identified for which termination does not depend on left-to-right execution. The only assumption about the selection rule is that derivations are input-consuming, that is, in each derivation step, the input arguments of the ...

Electropolymerized Aptasensor for Femtogram‐Level Cytokine Detection

Advanced Materials, EarlyView.
Electropolymerization of 3‐amino‐ʟ‐tyrosine creates ultrathin, smooth, and chemically robust pALT nanofilms with accessible carboxyl functionalities for direct aptamer immobilization. Integrated with fiber‐optic SPR and OECT platforms, these interfaces enable IL‐6 detection down to 100 fg mL−1 and provide a versatile route to bioelectronic sensing ...

Visualization of Shock Wave Phenomenon around a Sharp Cone Model at Hypersonic Mach Number in a Shock Tunnel using High Speed Schlieren Facility

Journal of Applied Fluid Mechanics, 2019
The flow field around a Sharp cone model configuration has been investigated by means of Schlieren facility in hypersonic shock tunnel. The time dependent evolution of flow around a cone of angle 11.38° with base radius of 150mm has been visualized ...

Two-zone model for the broadband Crab nebula spectrum: microscopic interpretation

EPJ Web of Conferences, 2017
We develop a simple two-zone interpretation of the broadband baseline Crab nebula spectrum between 10−5 eV and ~ 100 TeV by using two distinct log-parabola energetic electrons distributions.

The Fermi bubbles as starburst wind termination shocks [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2014
Abstract The enhanced star formation in the inner 100 pc of the Galaxy launches a superwind at ∼1600 km s-1 for M82-like parameters. The ram pressure of the wind is very low compared to more powerful starburst winds. I show that halo gas stops the wind a few kpc from the Galactic Centre.

Equilibrium Layoff As Termination of a Dynamic Contract [PDF]

In a dynamic model of the labor market with moral hazard, equilibrium layoff is modeled as termination of an optimal long-term contract. Termination, together with compensation (current and future), is used as an incentive device to induce worker efforts.
