An amplitude spectral tonometer

AbstractVariations in harmonic amplitudes of one-dimensional recurrent signals of the types encountered in medical tonometry are analyzed over finite length records by single Fourier series. Two regularizational algorithms, one differentiation-invoking and the other differentiation-free, are advanced for the design of a universal amplitude spectral “tonometer” for such signals

The unique Wolverine HREE deposit, Browns Range area, Western Australia

The Wolverine deposit is the largest of a number of REE ore bodies located in the Browns Range area of the Tanami region, Western Australia. These deposits collectively represent one of the worlds’ richest sources of dysprosium and other critical HREE. The Wolverine deposit consists of xenotime [(Y,REE)PO4] and minor florencite [(REEAl3(PO4)2(OH)6] mineralisation in hydrothermal lodes within massive arkosic sandstones. Small alkali granite and pegmatite bodies also intruded the sandstone in the region. Steeply dipping mineralisation is associated with silicification at major fault junctions, and occurs mostly as; 1) high grade, low tonnage lodes with large (>10m long and 1m wide) veins and chaotic breccias of massive, anhedral xenotime (±quartz, ±hematite, ±sericite), and; 2) low grade, probably higher tonnage disseminated mm-scale xenotime-quartz veins and crackle breccias in which xenotime grains occur in a number of morphological types, mainly blade-like and pyramidal overgrowth on pre-existing xenotime grains. U-Pb dating and isotopic analysis of detrital zircon grains from arkose samples from across the district yielded a single age population of ~3.1 (±~0.1) Ga (corrected for lead loss), which is interpreted to be the maximum depositional age of the sandstones. This age is significantly older than the granitic rocks in the region ( ca. 1.8 to 2.5 Ga), indicating that there is (previously unknown) Mesoarchean basement within the North Australian Craton. Highly unradiogenic Hf isotope data for these zircons combined with unradiogenic Nd isotope values for ore xenotime indicate that old (Early Archean or Hadean?) crustal components contributed to the formation of ~3.1 Ga basement rocks and potentially the xenotime ore bodies. Work is ongoing to understand the temporal evolution of the deposit, the source of the REE (i.e., mantle versus old crustal) and the processes of transport and precipitation of HREE to form the deposit

A majority of Brazilian patients with rheumatoid arthritis HLA-DRB1 alleles carry both the HLA-DRB1 shared epitope and anti-citrunillated peptide antibodies

The objective of the present study was to evaluate the contribution of the shared epitope (SE), the rheumatoid arthritis (RA) protection model, and the occurrence of anti-cyclic citrullinated peptide (anti-CCP) antibodies in RA patients from a genetically diverse population. One hundred and forty Brazilian RA patients and 161 matched controls were typed for HLA-DRB1 alleles using amplified DNA hybridized with sequence-specific oligonucleotide probes or primers. Patients were stratified according to the presence or absence of SE (DRB1*0401, *0404, *0405, *0101, *1001, and *1402), of the DERAA alleles (DRB1*0103, *0402, *1102, *1103, *1301, *1302, and *1304), and X (all other alleles). Anti-CCP antibodies were measured by ELISA. The combined frequency of SE-positive alleles was significantly greater (76.4 vs 23.6%, P < 0.0001) than the controls. The SE/SE and SE/X genotypes were over-represented (P < 0.0001, OR = 6.02) and DERAA/X was under-represented in RA patients (P < 0.001, OR = 0.49), whereas the frequencies of the SE/DERAA, X/X and X/DERAA genotypes were not significantly different from controls. The frequency of anti-CCP antibodies was higher in SE-positive patients than in SE-negative patients (64.6 vs 44.7%, P = 0.03; OR = 2.25). Although the Brazilian population is highly miscegenated, the results of this study support the findings observed in most genetically homogeneous populations with RA; however, they are not mutually exclusive but rather complementary. The participation of DRB1-DERAA alleles in protection against RA was also observed (OR = 0.4; 95%CI = 0.23-0.68).CNPqFAEP

Radio Observations of Four Active Galactic Nuclei Hosting Intermediate-mass Black Hole Candidates: Studying the Outflow Activity and Evolution

Observational searches for intermediate-mass black holes (IMBHs; 102-106 M ⊙) include relatively isolated dwarf galaxies. For those that host active galactic nuclei (AGNs), the IMBH nature may be discerned through the accretion-jet activity. We present radio observations of four AGN-hosting dwarf galaxies, which potentially harbor IMBHs. Very large array (VLA) observations indicate steep spectra (indices of −0.63 to −1.05) between 1.4 and 9 GHz. However, a comparison with the 9 GHz in-band spectral index shows a steepening for GH047 and GH158 (implying older/relic emission) and flattening for GH106 and GH163 (implying recent activity). Overlapping emission regions in the VLA 1.4 GHz and our very long baseline array (VLBA) 1.5 GHz observations, and possibly symmetric pc-scale extensions, are consistent with recent activity in the latter two. Using the compact VLBA radio luminosity, X-ray luminosity (probing the accretion activity), and the black hole masses, all AGNs are found to lie on the empirical fundamental plane relation. The four AGNs are radio-quiet with relatively higher Eddington ratios (0.04-0.32) and resemble X-ray binaries during spectral state transitions that entail an outflow ejection. Furthermore, the radio to X-ray luminosity ratio log R X of −3.9 to −5.6 in these four sources support the scenarios that include corona mass ejection from the accretion disk and wind activity. The growth to kpc-scales likely proceeds along a similar trajectory to young AGNs and peaked spectrum sources. These complex clues can thus aid in the detection and monitoring of IMBHs in the nearby universe

A tale of two localities: Healthy Eating on a restricted income

Objective: To determine the availability and affordability of a healthy food basket and to model how those on low-incomes might manage. Design and methodology: After determining access and availability of key items from shops in two localities, called Deepdale and Ingol, a healthy food basket was developed. From this a week’s healthy menu was devised for a mother and two children, then availability of the ingredients was checked using data collected from the shops and costed. The baskets represented the cultural preferences of White British and South Asian families informed by participatory work with both these groups. We chose the income level for a family entitled to income support and child allowance. Results: Analysis of the availability of some healthy options such as brown bread, wholemeal pasta, and brown rice showed they were not widely available within shops in the two areas. The price of the ‘White British’ basket in the area of Ingol was £70.61 (lowest price). For comparable goods in the area of Deepdale, using the most expensive shopping basket, the price for the same basket was £42.47. A South Asian family shopping at a major supermarket outlet in Deepdale would pay £47.05. Using local shops they could pay between £38.59 and £44.28 by seeking out the best bargains in five shops (including some top-up items from a national supermarket). At the time of the research a mother with two children entitled to income support and child allowance would have to spend 28–32 per cent of her income in local shops and 34 per cent in a supermarket to buy a basket of healthy goods. This compared to the national average of 10–12 per cent of income being spent on food purchases. Conclusions: Prices varied enormously between the two areas. Local shops in one area offered a comparable price to shopping in the supermarkets. The Ingol area, with a large white working class population, was particularly poorly served for those on low incomes and the range of choices restricted. The percentages spent on food to meet the requirements of our healthy baskets and menus show that more than the national average – in both absolute and relative terms – would have to be spent to eat healthily. For the vulnerable and price dependent poor in Preston this will mean having to spend more on food and possibly more on travel to access basics, a healthy diet will cost more, while proportionally an unhealthy diet, as can be found in fast food outlets, may not be as expensive when other costs such as cooking are taken into account. An overall rise in food prices of 5 per cent will reduce living standards among high-income consumers by approximately 3 per cent; for low-income consumers this reduction in an already poor diet could be as high as 20 per cent. What we have demonstrated is the usefulness of local studies to highlight micro-differences in relatively small areas (Preston city) and the different experiences of groups in accessing healthy foods, and thus the need to refine interventions at a local level
