MAXIMAL ACCELERATION OR MAXIMAL ACCELERATIONS? [PDF]

open access: yesInternational Journal of Modern Physics D, 2003
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.

Acceleration Methods [PDF]

open access: yesFoundations and Trends® in Optimization, 2021
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.

Pepper-pot emittance measurement of laser-plasma wakefield accelerated electrons [PDF]

open access: yes, 2009
The transverse emittance is an important parameter governing the brightness of an electron beam. Here we present the first pepper-pot measurement of the transverse emittance for a mono-energetic electron beam from a laser-plasma wakefield accelerator ...

Masked Accelerators and Instruction Set Extensions for Post-Quantum Cryptography

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2021
Side-channel attacks can break mathematically secure cryptographic systems leading to a major concern in applied cryptography. While the cryptanalysis and security evaluation of Post-Quantum Cryptography (PQC) have already received an increasing research

Is 70Zn(d,x)67Cu the Best Way to Produce 67Cu for Medical Applications?

open access: yesFrontiers in Medicine, 2021
The pair of copper radionuclides 64Cu/67Cu (T1/2 = 12. 7 h/61.8 h) allows, respectively, PET imaging and targeted beta therapy. An analysis of the different production routes of 67Cu with charged particles was performed and the reaction 70Zn(d,x) route ...
