No anticorrelation between cyclotron line energy and X-ray flux in 4U 0115+634

We report on an outburst of the high mass X-ray binary 4U 0115+634 with a pulse period of 3.6 s in 2008 March/April as observed with RXTE and INTEGRAL. During the outburst the neutron star’s luminosity varied by a factor of 10 in the 3–50 keV band. In agreement with earlier work we find evidence of five cyclotron resonance scattering features at ~10.7, 21.8, 35.5, 46.7, and 59.7 keV. Previous work had found an anticorrelation between the fundamental cyclotron line energy and the X-ray flux. We show that this apparent anticorrelation is probably due to the unphysical interplay of parameters of the cyclotron line with the continuum models used previously, e.g., the negative and positive exponent power law (NPEX). For this model, we show that cyclotron line modeling erroneously leads to describing part of the exponential cutoff and the continuum variability, and not the cyclotron lines. When the X-ray continuum is modeled with a simple exponentially cutoff power law modified by a Gaussian emission feature around 10 keV, the correlation between the line energy and the flux vanishes, and the line parameters remain virtually constant over the outburst. We therefore conclude that the previously reported anticorrelation is an artifact of the assumptions adopted in the modeling of the continuum.

Deploying the energy incentive: reinforcing EU integration in South-East Europe. CEPS Policy Brief No. 296, July 2013

This Policy Brief urges the European Union to consider reinforcing the Energy Community by further Europeanising the Energy Community Treaty. It argues that the level of dysfunctionality with respect to the rule of law and corruption will make it very hard to establish a pathway for accession for most Balkan states. However, the demand across the region for a sustainable, competitive and stable energy sector creates an ‘energy incentive’ that the Union can leverage to improve the rule of law and adherence to European rules. Furthermore, a juridical strengthening of the Energy Community Treaty will also strengthen the hand of those parties supporting energy liberalisation rules across the region, such as independent businesses, consumers and NGOs. In addition, there is likely to be significant spill-over effects from decisions of a European Energy Community Court operating in the region on the rule of law in general and the accession process in particular.

Negotiating an Energy Deal under TTIP: Drivers and Impediments to U.S. Shale Exports to Europe

The problem of global security of energy supply is growing in importance. TTIP negotiations represent an opportunity to improve energy security in Europe and negotiate a legal framework for bilateral trade in energy, which could serve as a model for future negotiations at a multilateral level. This paper explores some of the thorniest legal, geopolitical, and economic issues that need to be taken up by TTIP negotiators for the promotion of a secure and sustainable trade in energy between the United States and European Union. It gives an account of the most recent developments in the TTIP negotiations on energy and examines the link between a possible legal framework for energy trade under TTIP and other energy-related regional and international fora. The paper critically assesses the negotiating positions of the European Union and the United States in light of their reciprocal energy profiles and needs. It offers an overview of the critical items most likely to be on top of the TTIP agenda on energy based on a comparative analysis of energy provisions in E.U. and U.S. legislation and in light of the both parties’ interests. Finally, it discusses the main driving forces and inhibiting factors capable of facilitating or rather impeding a successful conclusion of an energy trade deal between the United States and the European Union.

Fair Access to Energy Resources, Market Transfers and Climate Change in the WTO

This paper addresses the issues of dual pricing and export restrictions in the energy sector, stressing the comparability of their economic and climate change impacts. It assesses whether WTO disciplines relevant and applicable to such practices are well-equipped to ensure fair access to energy resources. It finds that relevant GATT disciplines are overall deficient in the case of dual pricing and export taxes, while the landscape of WTO-plus obligations generally consisting of a network of narrowly tailored commitments. It discusses possible avenues to address such practices under the ASCM to the extent that they distort domestic energy prices and subsidize consumption of cheap fossil fuels

Direct energy conversion devices : a literature search /

Included are 208 unclassified references on nuclear direct energy conversion devices. Major emphasis is placed on auxiliary power devices suitable for use in satellites including reports on nuclear batteries, thermoelectric cells, thermionic conversion, and all phases of the SNAP program, although not all SNAP devices employ direct conversion. This search supersedes a previous search, TID-3540, Isotopic Power and Thermionic Conversion, compiled by Raymond L. Scott in December 1959.
