Debugging is difficult and costly, especially for production failures. To aid developers, we enhance core memory dumps produced by crashing applications with lightweight, tunable tracing. We propose two complementary forms of tracing, path traces and global coverage, and demonstrate that they can provide substantial postmortem analysis benefit at low cost. Recent work focuses on the interplay o...

BACKGROUND Performance test of the China Fusion Engineering Test Reactor (CFETR) central solenoid (CS) and toroidal field (TF) insert coils is of great importance to evaluate the CFETR magnet performance in relevant operation conditions. The superconducting magnet of the coil test facility for CFETR is being designed with the aim of providing a background magnetic field to test the CFETR CS ins...

Abstract The operation modes for the proposed FCC-ee collider foresee a very small beam spot size and stored energies of up to 20.6 MJ in Z production. This necessitates dedicated dumping system. To reduce complexity system as well minimize required space, an optimized, semi-passive has been designed is presented here. dilution done with defocusing triplet structure, followed by passive diluter...

M ore than 50 years ago, a French physician, Dr. Jean Vague, noted that complications in his obese patients had more to do with where the fat was deposited than how much was deposited (1). Dr. Vague is credited with developing the terms ‘‘android’’ and ‘‘gynoid’’ obesity. Android is the high-risk type of obesity typically found in males, where the fat is deposited centrally (apple shape). Gynoi...

Sequence analysis of the 330-kb double-stranded DNA genome of Paramecium bursaria chlorella virus-1 revealed an open reading frame A674R that encodes a protein with up to 53% amino acid identity to a recently discovered new class of thymidylate synthases, called ThyX. Unlike the traditional thymidylate synthase, ThyA, that uses methylenetetrahydrofolate (CH(2)H(4)folate) as both a source of the...
