Measure of stability of a Pareto optimal solution to a vector integer programming problem with fixed surcharges in the l1 and l∞ metrics [PDF]

Computer Science Journal of Moldova, 2005
In this paper we consider a vector integer programming problem with Pareto principle of optimality for the case where partial criteria belong to the class of separable piecewise linear functions. The limit level of the initial data's perturbations in the

Neutron-star Radius Constraints from GW170817 and Future Detections [PDF]

, 2017
We introduce a new, powerful method to constrain properties of neutron stars (NSs). We show that the total mass of GW170817 provides a reliable constraint on the stellar radius if the merger did not result in a prompt collapse as suggested by the ...

Epidemiology, classification, treatment and mortality of distal radius fractures in adults: an observational study of 23,394 fractures from the national Swedish fracture register

BMC Musculoskeletal Disorders, 2020
Background Distal radius fractures are the most common of all fractures. Optimal treatment is still debated. Previous studies report substantial changes in treatment trends in recent decades. Few nation-wide studies on distal radius fracture epidemiology

Modeling of the Tail Slap for an Underwater Projectile within Supercavitation

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
Detailed process of the tail slap for an underwater projectile in supercavitation is studied in this paper. Firstly, the horizontal equation of motion for the projectile and a dynamic model of the projectile’s tail slap are introduced through a mathematical derivation, including a simple harmonic motion model of the projectile within the ...

An asteroseismic view of the radius valley: stripped cores, not born rocky [PDF]

Monthly notices of the Royal Astronomical Society, 2017
Various theoretical models treating the effect of stellar irradiation on planetary envelopes predict the presence of a radius valley, i.e. a bimodal distribution of planet radii, with super-Earths and sub-Neptune planets separated by a valley at around ...

Statistical azimuthal structuring of the substorm onset arc: Implications for the onset mechanism

Geophysical Research Letters, Volume 44, Issue 5, Page 2078-2087, 16 March 2017., 2017
Abstract The onset of an auroral substorm is generally thought to occur on a quiet, homogeneous auroral arc. We present a statistical study of independently selected substorm onset arcs and find that over 90% of the arcs studied have resolvable characteristic spatial scales in the form of auroral beads.

Analysis of the Conformally Flat Approximation for Binary Neutron Star Initial Conditions

Advances in Astronomy, Volume 2017, Issue 1, 2017., 2017
The spatially conformally flat approximation (CFA) is a viable method to deduce initial conditions for the subsequent evolution of binary neutron stars employing the full Einstein equations. Here we analyze the viability of the CFA for the general relativistic hydrodynamic initial conditions of binary neutron stars.

Vacuum Condensate, Geometric Phase, Unruh Effect, and Temperature Measurement

Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015
In our previous work the possibility to use the Aharonov‐Anandan invariant as a tool in the analysis of disparate systems has been shown, including Hawking and Unruh effects, as well as graphene physics and thermal states. We show that the vacuum condensation, characterizing such systems, is also related with geometric phases and we analyze the ...

Singular limit and long-time dynamics of Bresse systems

, 2017
The Bresse system is a valid model for arched beams which reduces to the classical Timoshenko system when the arch curvature $\ell=0$. Our first result shows the Timoshenko system as a singular limit of the Bresse system as $\ell \to 0$.
