To fabricate 10–16 Tesla high-field accelerator magnets, the high-Jc Nb3Sn superconductor is one of the most practical choices. However, it is a brittle material and is strain-sensitive.

New measurements of 92Mo(γ, n) and (γ, 3n) reactions using laser-driven bremsstrahlung γ-ray
The flux-weighted average cross sections and isomeric ratios of 92Mo(γ, n)91m,gMo and 92Mo(γ, 3n)89Mo reactions were measured through activation methods.

The accelerated acceleration of the universe
We present a simple mechanism which can mimic dark energy with an equation of state w < -1 as deduced from the supernova data. We imagine that the universe is accelerating under the control of a quintessence field, which is moving up a very gently sloping potential.

Vertical evolution of auroral acceleration at substorm onset [PDF]
This study describes the onset process of auroral substorms in connection with the vertical evolution of auroral particle acceleration, on the basis of auroral kilometric radiation (AKR) dynamics.

Acceleration of Material Waves in Fermi Accelerator [PDF]
Cold Atoms bouncing on modulated atomic mirror exhibits acceleration and dynamical localization subject to modulated strength. We explain characteristics of acceleration and define control parameters in terms of effective Planck′s constant. We show that the effective Planck′s constant plays a vital role in limiting classical‐like overall linear growth

MAXIMAL ACCELERATION OR MAXIMAL ACCELERATIONS? [PDF]
We review the arguments supporting the existence of a maximal acceleration for a massive particle and show that different values of this upper limit can be predicted in different physical situations.

This monograph covers some recent advances in a range of acceleration techniques frequently used in convex optimization. We first use quadratic optimization problems to introduce two key families of methods, namely momentum and nested optimization schemes. They coincide in the quadratic case to form the Chebyshev method.
