Charge-based quantum computing using single donors in semiconductors

Solid-state quantum computer architectures with qubits encoded using single atoms are now feasible given recent advances in the atomic doping of semiconductors. Here we present a charge qubit consisting of two dopant atoms in a semiconductor crystal, one of which is singly ionized. Surface electrodes control the qubit and a radio-frequency single-electron transistor provides fast readout. The calculated single gate times, of order 50 ps or less, are much shorter than the expected decoherence time. We propose universal one- and two-qubit gate operations for this system and discuss prospects for fabrication and scale up.

Nitric oxide donors inhibit 5-hydroxytryptamine (5-HT) uptake by the human 5-HT transporter (SERT)

1 The aim was to test the hypothesis that nitric oxide ( NO) donor drugs can inhibit the 5-hydroxytryptamine (5-HT) transporter, SERT. 2 The NO donors, MAHMA/NO ( a NONOate; (Z)-1-[N-methyl-N-[6-(N-methylammoniohexyl)amino]]diazen- 1-ium-1,2-diolate), SIN-1 ( a sydnonimine; 5-amino-3-(4-morpholinyl)-1,2,3-oxadiazolium chloride), FK409 ( an oxime; (+/-)-(4-ethyl-2E-(hydroxyimino)-5-nitro-3E-hexenamide)) and peroxynitrite, but not Angeli's salt ( source of nitroxyl anion) or sodium nitrite, caused concentration-dependent inhibition of the specific uptake of [H-3]- 5-HT in COS-7 cells expressing human SERT. 3 Superoxide dismutase (150 U ml(-1)) plus catalase ( 1200 U ml(-1)), used to remove superoxide and hence prevent peroxynitrite formation, prevented the inhibitory effect of SIN-1 ( which generates superoxide) but not of MAHMA/NO or FK409. 4 The inhibitory effects of the NO donors were not affected by the free radical scavenger, hydroxocobalamin (1 mM) or the guanylate cyclase inhibitor, ODQ (1H-[ 1,2,4] oxadiazolo[4,3-a] quinoxalin-1-one; 3 muM). 5 L-Cysteine ( 1 mM; source of excess thiol residues) abolished or markedly reduced the inhibitory effects of MAHMA/NO, SIN-1, FK409 and peroxynitrite. 6 It is concluded that inhibition of SERT by the NO donors cannot be attributed exclusively to NO free radical nor to nitroxyl anion. It does not involve guanosine-3',5'-cyclic monophosphate, but may involve nitrosation of cysteine residues on the SERT protein. Peroxynitrite mediates the effect of SIN-1, but not the other drugs. 7 Data in mice with hypoxic pulmonary hypertension suggest that SERT inhibitors may attenuate pulmonary vascular remodelling. Thus, NO donors may be useful in pulmonary hypertension, not only as vasodilators, but also because they inhibit SERT, provided they display this effect in vivo at appropriate doses.

Desperately seeking donors: The 'saviour siblings' decision in quintaville v human fertilisation embryology authority (UK)

The recent House of Lords decision in Quintavalle v Human Fertilisation and Embryology Authority has raised difficult and complex issues regarding the extent to which embryo selection and reproductive technology can be used as a means of rectifying genetic disorders and treating critically ill children. This comment outlines the facts of Quintavalle and explores how the House of Lords approached the legal, ethical and policy issues that arose out of the Human Fertilisation and Embryology Authority's (UK) decision to allow reproductive and embryo technology to be used to produce a 'saviour sibling' whose tissue could be used to save the life of a critically ill child. Particular attention will be given to the implications of the decision in Quintavalle for Australian family and medical law and policy. As part of this focus, the comment explores the current Australian legislative and policy framework regarding the use of genetic and reproductive technology as a mechanism through which to assist critically ill siblings. It is argued that the present Australian framework would appear to impose significant limits on the medical uses of genetic technology and, in this context, would seem to reflect many of the principles that were articulated by the House of Lords in Quintavalle.

The Proinflammatory Environment in Potential Heart and Lung Donors: Prevalence and Impact of Donor Management and Hormonal Therapy

BACKGROUND: Brain stem death can elicit a potentially manipulable cardiotoxic proinflammatory cytokine response. We investigated the prevalence of this response, the impact of donor management with tri-iodothyronine (T3) and methylprednisolone (MP) administration, and the relationship of biomarkers to organ function and transplant suitability. METHODS: In a prospective randomized double-blinded factorially designed study of T3 and MP therapy, we measured serum levels of interleukin-1 and -6 (IL-1 and IL-6), tumor necrosis factor-alpha (TNF-alpha), C-reactive protein, and procalcitonin (PCT) levels in 79 potential heart or lung donors. Measurements were performed before and after 4 hr of algorithm-based donor management to optimize cardiorespiratory function and +/-hormone treatment. Donors were assigned to receive T3, MP, both drugs, or placebo. RESULTS: Initial IL-1 was elevated in 16% donors, IL-6 in 100%, TNF-alpha in 28%, CRP in 98%, and PCT in 87%. Overall biomarker concentrations did not change between initial and later measurements and neither T3 nor MP effected any change. Both PCT (P =0.02) and TNF-alpha (P =0.044) levels were higher in donor hearts with marginal hemodynamics at initial assessment. Higher PCT levels were related to worse cardiac index and right and left ventricular ejection fractions and a PCT level more than 2 ng x mL(-1) may attenuate any improvement in cardiac index gained by donor management. No differences were observed between initially marginal and nonmarginal donor lungs. A PCT level less than or equal to 2 ng x mL(-1) but not other biomarkers predicted transplant suitability following management. CONCLUSIONS: There is high prevalence of a proinflammatory environment in the organ donor that is not affected by tri-iodothyronine or MP therapy. High PCT and TNF-alpha levels are associated with donor heart dysfunction. (C) 2009 Lippincott Williams & Wilkins, Inc.

Reluctant donors? The Europeanization of international development policies in the New Member States

The European Union (EU) played an instrumental role in re-starting the international development policies in central and eastern European Member States, but questions remain about how far this policy area has been Europeanized since accession. Focusing on the Czech Republic, Hungary, Poland and Slovakia, this article investigates why the new donors have been reluctant to adopt the EU's development acquis more fully. The article traces the socialization processes offered by the EU's development policy rule-making and subsequent national rule implementation. The conclusions reveal three reasons why socialization has been weak: perceptions among the new Member States on the procedural legitimacy of the development acquis; low domestic resonance with the development acquis; and inconsistencies in the activities of norm entrepreneurs. The article contributes to our understanding of development policy in the EU – particularly how decision-making takes place within the Council and its working groups post-enlargement.

The East-Central European new donors:mapping capacity building and remaining challenges

In the past decade, the East-Central European countries were provided significant external capacity building assistance to help their emergence as donors of foreign aid. This paper aims to map these capacity development programmes and identify where they have helped and what challenges remain for the new donors. The main conclusion is that although capacity building has been instrumental in building organisational structures, working procedures and training staff, deeper underlying problems such as low levels of financing, lacking political will, the need for visibility and low staff numbers continue to hinder the new international development policies.

Aid allocation of the emerging Central and Eastern European donors

This paper examines the main characteristics of the (re-)emerging foreign aid policies of the Visegrád countries (the Czech Republic, Hungary, Poland, Slovakia), concentrating on the allocation of their aid resources. I adopt an econometric approach, similar to the ones used in the literature, for analysing the aid allocation of the OECD DAC donors. Using this approach, I examine the various factors that influence aid allocation of the Visegrád countries, using data for the years between 2001 and 2008. The most important conclusion is that the amount of aid a partner country gets from the four emerging donors is not influenced by the level of poverty or the previous performance of the recipients (measured by the level of economic growth or the quality of institutions). The main determining factor seems to be geographic proximity, as countries in the Western Balkans and the Post-Soviet region receive much more aid from the Visegrád countries than other recipients. Historical ties (pre-1989 development relations) and international obligations in the cases of Afghanistan and Iraq are also found to be significant explanatory factors. This allocation is in line with the foreign political and economic interests of these new donors. Although there are clear similarities between the four donors, this paper also identifies some individual country characteristics.
