E-Band Transformer-Based Differential 4-Way Power-Combining Amplifier

This paper presents the design and implementation of a differential 4-way power-combining amplifier operating at E-band. The proposed 4-way power combiner (4WPC) facilitates short interconnects to the PA cells, thereby resulting in reduced loss. Simple C-L-C and L-C networks are deployed in order to compensate inductive loading due to the routing lines that would otherwise introduce mismatch and subsequently increase overall loss. Realized in SiGe technology, the PA prototype delivered 13.2 dBm output-referred 1-dB compression point and 14.3 dBm saturated output power when operated from a single 3.3 V DC supply at 75 GHz.

The Scottish Reformations and the Origin of Religious and Civil Liberty in Britain and Ireland: Presbyterian Interpretations, c.1800-60

This article examines Presbyterian interpretations in Scotland and Ireland of the Scottish Reformations of 1560 and 1638–43. It begins with a discussion of the work of two important Presbyterian historians of the early nineteenth century, the Scotsman, Thomas McCrie, and the Irishman, James Seaton Reid. In their various publications, both laid the template for the nineteenth-century Presbyterian understanding of the Scottish Reformations by emphasizing the historical links between the Scottish and Irish churches in the early-modern period and their common theology and commitment to civil and religious liberty against the ecclesiastical and political tyranny of the Stuarts. The article also examines the commemorations of the National Covenant in 1838, the Solemn League and Covenant in 1843, and the Scottish Reformation in 1860. By doing so, it uncovers important religious and ideological linkages across the North Channel, including Presbyterian evangelicalism, missionary activity, church–state relationships, religious reform and revival, and anti-Catholicism

Effectiveness of a Multifaceted Intervention for Potentially Inappropriate Prescribing in Older Patients in Primary Care: A Cluster-Randomized Controlled Trial (OPTI-SCRIPT Study)

PURPOSE Potentially inappropriate prescribing (PIP) is common in older people and can result in increased morbidity, adverse drug events, and hospitalizations. The OPTI-SCRIPT study (Optimizing Prescribing for Older People in Primary Care, a cluster-randomized controlled trial) tested the effectiveness of a multifaceted intervention for reducing PIP in primary care.

METHODS We conducted a cluster-randomized controlled trial among 21 general practitioner practices and 196 patients with PIP. Intervention participants received a complex, multifaceted intervention incorporating academic detailing; review of medicines with web-based pharmaceutical treatment algorithms that provide recommended alternative-treatment options; and tailored patient information leaflets. Control practices delivered usual care and received simple, patient-level PIP feedback. Primary outcomes were the proportion of patients with PIP and the mean number of potentially inappropriate prescriptions. We performed intention-to-treat analysis using random-effects regression.

RESULTS All 21 practices and 190 patients were followed. At intervention completion, patients in the intervention group had significantly lower odds of having PIP than patients in the control group (adjusted odds ratio = 0.32; 95% CI, 0.15–0.70; P = .02). The mean number of PIP drugs in the intervention group was 0.70, compared with 1.18 in the control group (P = .02). The intervention group was almost one-third less likely than the control group to have PIP drugs at intervention completion, but this difference was not significant (incidence rate ratio = 0.71; 95% CI, 0.50–1.02; P = .49). The intervention was effective in reducing proton pump inhibitor prescribing (adjusted odds ratio = 0.30; 95% CI, 0.14–0.68; P = .04).

CONCLUSIONS The OPTI-SCRIPT intervention incorporating academic detailing with a pharmacist, and a review of medicines with web-based pharmaceutical treatment algorithms, was effective in reducing PIP, particularly in modifying prescribing of proton pump inhibitors, the most commonly occurring PIP drugs nationally.

Yellow earthworms:Distinctive pigmentation associated with arsenic- and copper-tolerance in Lumbricus rubellus

Lumbricus rubellus Hoffmeister, inhabiting soil at the 19th century Devon Great Consols mine at Tavistock, Devon, UK, show high tolerance to Cu- and As-toxicity and frequently have a striking yellow coloration. Specimens from this site (mature and immature) and from an uncontaminated site on Lancaster University campus (mature) were photographed, and the slide images digitized and analyzed. All L. rubellus showed reddish-purple pigmentation of the body wall that declined in intensity posteriorly. The metal- and metalloid-resistant earthworms, whether mature or immature, showed yellowing in the posterior half of the body. The source of the coloration was intense yellow pigmentation of the chloragogenous tissue surrounding the alimentary canal. The yellow pigmentation is masked by reddish-purple body wall pigmentation anteriorly. Total As concentrations in tissues were determined for the anterior, middle and posterior sections of resistant and non-resistant L. rubellus. Highest concentrations were in the middle sections of the mature and immature resistant L. rubellus (36.17 ± 19.77 and 27.77 ± 9.02 mg As kg^-1, respectively). Resistant immature L. rubellus lost condition over 28 d in soil treated with 750 mg As kg^-1, possibly due to a higher metabolism, whilst there was no loss in condition for resistant mature L. rubellus in the treated soil. As far as the authors are aware, this is the first report of yellow pigmentation of this kind in earthworms. The pigmentation may provide a useful indicator of exposure/resistance to soil contamination. © 2002 Elsevier Science Ltd. All rights reserved.

Frequency of deletion 508 among Irish cystic fibrosis patients

We estimate the incidence of cystic fibrosis in Ireland to be at least 1 case per 1838 live births. We have analysed DNA from 44 Irish CF patients for the presence of deletion 508, using the polymerase chain reaction. The deletion was found in 76% of their chromosomes, and approximately 58% of the patients are homozygous for this deletion. Our results are not significantly different from those found in Canadian or UK patient populations, in which frequencies are higher than those found in Southern European countries.

Old Town Glasgow: Squalor, Agitation and City Improvements

In 1862, Glasgow Corporation initiated the first of a series of three legislative acts which would become known collectively as the City Improvements Acts. Despite having some influence on the nature of the built fabric on the expanding city as a whole, the most extensive consequences of these acts was reserved for one specific area of the city, the remnants of the medieval Old Town. As the city had expanded towards all points of the compass in a regular, grid-iron structure throughout the nineteenth century, the Old Town remained singularly as a densely wrought fabric of medieval wynds, vennels, oblique passageways and accelerated tenementalisation. Here, as the rest of the city began to assume the form of an ordered entity, visible and classifiable, one could still find and addresses such as ‘Bridgegate, No. 29, backland, stair first left, three up, right lobby, door facing’ (quoted in Pacione, 1995).

Unsurprisingly, this place, where proximity to the midden (dung-heap) was considered an enviable position, was seen by the authorities as a major health hazard and a source not only of cholera, but also of the more alarming typhoid epidemic of 1842. Accordingly, the demolitions which occurred in the backlands of the Old Town under the first of the acts, the Glasgow Police Act of 1862, were justified on health and medical grounds. But disease was not the only social problem thought to issue from this district. Reports from social reformers including Fredrick Engels suggested that the decay of the area’s physical fabric could be extended to the moral profile of its inhabitants. This was in such a state of degeneracy that there were calls for a nearby military barracks to be relocated to more salubrious climes because troops were routinely coming into contact ‘with the most dissolute and profligate portion of the population’ (Peter Clonston, Lord Provost, June 1861). Perhaps more worrying for the city fathers, however, was that the barracks’ arsenal was seen as a potential source of arms for the militant and often illegal cotton workers’ unions and organisations who inhabited the Old Town as well as the districts to the east. In fact, the Old Town and East End had been the site of numerous working class actions and riots since 1787, including a strike of 60,000 workers in 1820, 100,000 in 1838, and the so-called Bread Riots of 1848 where shouts of ‘Vive La Revolution’ were reported in the Gallowgate.

The events in Paris in 1848 precipitated Baron Hausmann’s interventions into that city. The boulevards were in turn visited by members of Glasgow Corporation and ultimately, it can be argued, provided an example for Old Town Glasgow. This paper suggests that the city improvement acts carried a similarly complex and pervasive agenda, one which embodied not only health, class conflict and sexual morality but also the more local condition of sectarianism. And, like in Paris, these were played out spatially in a extensive reconfiguration of the urban fabric of the Old Town which, through the creation of new streets and a railway yard, not only made it more amenable to large scale military manoeuvres but also, opened up the area to capitalist accumulation. By the end of the works, the medieval heritage of the Old Town had been almost completely razed, the working class and Catholic East End had, through the insertion of the railway yard, been isolated from the city centre and approximately 70,000 people had been made homeless.

Choosing Union Representation: The Role of Attitudes and Emotions

In the United States, most unions are recognized by a majority vote of employees through union representation elections administered by the government. Most empirical studies of individual voting behavior during union representation elections use a rational choice model. Recently, however, some have posited that voting is often influenced by emotions. We evaluate competing hypotheses about the determinants of union voting behavior by using data collected from a 2010 representation election at Delta Air Lines, a US-based company. In addition to the older rational choice framework, multiple regression results provide support for an emotional choice model. Positive feelings toward the employer are statistically significantly related to voting ‘no’ in a representation election, while positive feelings toward the union are related to a ‘yes’ vote. Effect sizes for the emotion variables were generally larger than those for the rational choice variables, suggesting that emotions may play a key role in representation election outcomes.

Étude de l’enzyme UGT2B28 et son rôle dans le cancer de la prostate

Contexte: L’inactivation des androgènes est majoritairement régulée par des enzymes du métabolisme de la famille des UDP-glucuronosyltransferase (UGT). Ce procédé métabolique permet de contrôler la biodisponibilité des hormones stéroïdiennes systémiques et locales. Objectif : L’objectif était d’étudier la relation entre l’expression de l’enzyme UDP-glucuronosyltransferase 2B polypeptide 28 (UGT2B28), impliquée dans la biotransformation des hormones, avec les niveaux hormonaux circulants, et les caractéristiques clinico-pathologiques dans le cancer de la prostate (CaP). Conception et participants : Nous avons utilisé dans cette étude la technique d’immunohostochimie à grande échelle (tissue microarray) sur les tissus de 239 patients ayant un CaP localisé. L’étude des 51 patients additionnels ne possédant pas l’enzyme UGT2B28 dans leur génome, a été effectuée pour confirmer l’importance de cette enzyme sur les niveaux hormonaux circulants. Résultats : La surexpression de l’enzyme UGT2B28 a été associée à des niveaux d’antigène prostatique spécifique (APS) au diagnostic plus faibles, à un score de Gleason plus élevé, à des marges et statuts nodaux positifs, et fut associée de façon indépendante au risque de progression. La surexpression de l’enzyme fut également associée à des niveaux circulants de testostérone (T) et dihydrotestostérone (DHT) plus élevés. Les patients n’exprimant pas le gène UGT2B28 avaient des niveaux plus bas de T (19%), de DHT (17%), de métabolites glucuronidés (18-38%), et des niveaux plus élevés du précurseur surrénalien androsténédione (36%). Conclusion : L’enzyme UGT2B28 modifie les niveaux circulants de T et DHT, et sa surexpression est associée avec un CaP à plus haut grade. Notre étude a permis de découvrir un nouveau rôle d’UGT2B28, celui de régulateur de la stéroïdogenèse, et a souligné l’interconnexion entre les capacités de biotransformation hormonale des cellules cancéreuses, des niveaux hormonaux, des caractéristiques clinicopathologiques et du risque de progression.
