We present hard to approximate problems in the following areas: systems of representatives, network ow, and longest paths in graphs. In each case we show that there exists some > 0 such that polynomial time approximation to within a factor of 2 n of the optimal implies that NP has quasi polynomial time deterministic simulations. The results are derived by reduction from two prover, one round pr...

We report the detection of a stable super-orbital period in the high-mass X-ray binary 2S 0114+650. Analyses of data from the Rossi X-ray Timing Explorer (RXTE) All-Sky Monitor (ASM) from 1996 January 5 to 2004 August 25 reveal a super-orbital period of 30.7 ± 0.1 d, in addition to confirming the previously reported neutron star spin period of 2.7 h and the binary orbital period of 11.6 d. It i...

We present the results of a detailed study of the high mass X-ray binary 2S 0114+650 made with the pointed instruments onboard the Rossi X-ray Timing Explorer. The spectral and temporal behaviour of this source was examined over the pulse, orbital, and super-orbital timescales, covering∼2 cycles of the 30.7 d super-orbital modulation. Marginal evidence for variability of the power law photon in...
