Broken particle-hole symmetry at atomically flat a-axis YBa2Cu3O7-d interfaces

We have studied quasiparticle tunneling into atomically flat a-axis films of YBa2Cu3O7-d and DyBa2Cu3O7-d through epitaxial CaTiO3 barriers. The junction heterostructures were grown by oxide molecular beam epitaxy and were carefully optimized using in-situ monitoring techniques, resulting in unprecedented crystalline perfection of the superconductor/insulator interface. Below Tc, the tunneling conductance shows the evolution of a large unexpected asymmetrical feature near zero bias. This is evidence that superconducting YBCO crystals, atomically truncated along the lobe direction with a titanate layer, have intrinsically broken particle-hole symmetry over macroscopically large areas.Comment: 15 pages, 4 figures; v2 includes minor changes in concluding paragraph to match PRL versio

Outlook and appraisal [November 1985]

The Scottish economy, like that of the UK as a whole, looks set to experience a substantial shift in the relative importance of the factors determining growth in the coming year. As discussed elsewhere in the Commentary (see British Economy), growth in the recent past has been driven mainly by the expansion of investment and exports. With the interrelated factors of sterling's strength and continuing high real UK interest rates operating against a background of some deceleration in the growth of world trade, the prospect is that these influences will be largely replaced by the re-emergence of consumers' expenditure as the principal determinant of growth

The Scottish economy [November 1985]

With the inauguration of the quarterly Scottish Business Survey (SBS) in September 1984 there are now two regular up-to-date indicators of trends in the Scottish industrial sector. The combination of the new survey and the long-standing CBI Industrial Trends Survey provides a comprehensive assessment of trends in Scottish industry

The British economy [November 1985]

In his November Statement the Chancellor of the Exchequer has forecast continuing expansion of the economy during 1986. The recent growth of exports and investment is not expected to be maintained but consumer spending, boosted by higher real earnings and tax cuts in the Spring Budget, will rise

Cross-Sectional Associations Bet ween Abdominal and Thoracic Adipose Tissue Compartments and Adiponectin and Resistin in the Framingham Heart Study

OBJECTIVE: To test the association of regional fat depots with circulating adiponectin and resistin concentrations and to assess the potential mediating effect of adipokines on associations between abdominal fat depots and cardiometabolic risk factors. RESEARCH DESIGN AND METHODS: Participants from the Framingham Heart Study offspring cohort (n = 916, 55% women; mean age 59 years) free of cardiovascular disease underwent computed tomography measurement of visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), pericardial fat, and intrathoracic fat volumes and assays of circulating adiponectin and resistin. RESULTS: VAT, SAT, pericardial fat, and intrathoracic fat were negatively correlated with adiponectin (r = −0.19 to −0.34, P < 0.001 [women]; r = −0.15 to −0.26, P < 0.01 [men] except SAT) and positively correlated with resistin (r = 0.16–0.21, P < 0.001 [women]; r = 0.11–0.14, P < 0.05 [men] except VAT). VAT increased the multivariable model R2 for adiponectin from 2–4% to 10–13% and for resistin from 3–4% to 3–6%. Adjustment for adipokines did not fully attenuate associations between VAT, SAT, and cardiometabolic risk factors. CONCLUSIONS: Adiponectin and resistin are correlated with fat depots cross-sectionally, but none of the adipokines can serve as surrogates for the fat depots. Relations between VAT, SAT, and cardiometabolic risk factors were not fully explained by adiponectin or resistin concentrations.National Insitute's of Health National Heart, Lung, and Blood Institute’s Framingham Heart Study (N01-HC-25195); the National Institutes of Health; National Center for Research Resources; General Clinical Research Centers Program (M01-RR-01066); Career Development Award from the American Diabetes Association; National Institute of Diabetes and Digestive and Kidney Diseases (K24 DK080140, RO1 DK080739); National Heart, Lung, and Blood Institute, National Institutes of Health (2K24HL04334

The British economy [August 1985]

The pace of economic growth rose above the underlying growth rate in the first half of 1985 as a consequence of recovery from the miners' dispute and first quarter bunching of investment expenditure. In response to higher interest rates and the Chancellor's continuing commitment to the Medium Term Financial Strategy, sterling has strengthened and has remained resilient in the face of continuing uncertanties concerning oil prices. Output is set to grow by more than 3% this year before falling back as the impetus of the rebound from the miners' dispute diminishes and investment expenditure slackens. This slowdown in activity is likely to be reinforced by the current levels of the exchange rate and of interest rates

The world economy [August 1985]

The recovery in the world economy which began in 1982 now appears to be moving out of its fastest growth phase. With the US economy growing more slowly in the first half of 1985 than in the corresponding period of 1984, the previous marked differences in growth rates between the US and the European economies are being eroded. Indeed, a number of European countries look set to achieve faster growth during 1984 than the US. Largely due to slower US growth, world trade is likely to expand this year by around 5J-6S as compared to 9% last year. The Bonn economic summit in May and subsequent policy statements provide no indications that the slackening momentum in the world economy is to be compensated for by reflation elsewhere
