Are UK otorhinolaryngologists maintaining their research output?
Authors: Kulkarni K , Kulkarni M , Ramsden J , Silva P 
Published: May 2013

AbstractBackground:In the general surgical and anaesthetic literature, there has been a decline in research output originating from the UK. This study analysed the 10 globally leading and 2 UK leading otorhinolaryngology journals to determine whether this trend was also reflected within otorhinolaryngology.Methods:Citable research output was analysed from 4 individual years, over a 10-year period (2000–2010), to determine absolute output, geographical mix and article type.Results:The proportion of research output from the UK and Ireland grew 22.8 per cent among the leading global otorhinolaryngology journals, but fell 28.6 per cent among the leading two UK otorhinolaryngology journals. The converse trend was true for the USA and Canada. Output from European and the rest of the world grew among both sets of journals, while Japanese output fell. ‘Research’ articles remained the most prevalent type.Conclusion:These results are encouraging as they refute the fall in UK research output observed by other authors. In the face of growing challenges, it is important to maintain published output so that the fate that has befallen other specialties is not mirrored within UK otorhinolaryngology.
Computed tomography and magnetic resonance imaging findings for primary middle-ear carcinoma
Authors: Zhang F , Sha Y 
Published: May 2013

AbstractObjective:This study aimed to investigate the computed tomography and magnetic resonance imaging findings of primary middle-ear carcinoma.Methods:In this retrospective study of 13 patients with primary middle-ear carcinoma, we collected pre- and post-contrast magnetic resonance images for all 13 cases, high-resolution computed tomography scans for 11 cases, and conventional computed tomography scans with contrast for 2 cases.Results:Soft-tissue masses were mainly located in the tympanum, tympanic sinus and deep within the external auditory canal, and involved the jugular fossa (9 of 13 patients), middle cranial fossa (5/13), parotid gland (2/13) and temporomandibular joint fossa (1/13). An irregular, ‘moth-eaten’ bone destruction pattern was seen on high-resolution computed tomography images, most commonly in the eustachian tube (9/13), jugular foramen (9/13) and facial nerve canal (7/13). On non-contrast magnetic resonances images, masses were isointense or slightly hypointense on T1-weighted images, and isointense or slightly hyperintense on T2-weighted images. On post-contrast images, lesions were moderately and homogeneously enhanced in seven cases and inhomogeneously enhanced in six.Conclusion:High-resolution computed tomography precisely detects regions of bone destruction, whereas MRI can better assess soft-tissue tumour margins, intracranial extension and vessel patency. Eustachian tube erosion is an important characteristic of primary middle-ear carcinoma.
A new kind of solid-state Marx generator based on transformer type magnetic switches
Authors: Zhang Yu , Liu Jinliang 
Published: May 2013

AbstractIn this paper, a new kind of solid-state Marx generator based on synchronous transformer type magnetic switches (TTMS) is put forward, and the TTMSs with new winding structures are used to substitute all the spark gaps in the traditional Marx generator for the purposes of solidification and long life time. As the new type of TTMS with high step-up ratio and low saturated inductances is employed, the proposed Marx generator becomes a compact combination of pulse transformer, magnetic switch, and Marx capacitors. The stages of the Marx capacitors can be synchronously charged in parallel before the magnetic core saturates, and these Marx capacitors also can synchronously discharge in series. The establishing time of the proposed Marx generator is at ns range. As the new type of self-reset TTMS is used, the input voltage of the Marx generator decreases to a low level less than 1 kV while the output voltage can easily reach a high level ranging from dozens of kV to hundreds of kV.
Special values of L-functions for Saito–Kurokawa lifts
Authors: BROWN JIM , PITALE AMEYA 
Published: May 2013

AbstractIn this paper we obtain special value results for L-functions associated to classical and paramodular Saito–Kurokawa lifts. In particular, we consider standard L-functions associated to Saito–Kurokawa lifts as well as degree eight L-functions obtained by twisting with an automorphic form defined on GL(2). The results are obtained by combining classical and representation theoretic arguments.

Published: May 2013

SummaryIn the Karoo region of South Africa, eagles nesting on high voltage power pylons are responsible for frequent short-circuits or faults, which reduce the quality of commercial power supply and escalate costs to the country’s energy supplier, Eskom. Between 2002 and 2006 we conducted annual helicopter surveys of eagle nests on 1,400 km of power line and located 139 large nest structures, making up 96 eagle territories occupied by three species: Martial EaglePolemaetus bellicosus(66 pairs), Verreaux’s EagleAquila verreauxii(13 pairs) and Tawny EagleAquila rapax(17 pairs), and detailed 357 pair-years of breeding activity, including 241 breeding attempts. Roost sites and active nests were associated with line faulting, and more so at particular pylon configurations. We developed a three-step management plan to reduce eagle-related faulting while still accommodating eagles on the power lines: (i) all (potentially) problematic nests were relocated from high-risk positions above the power conductors, to specially provided platforms placed below the conductors; (ii) perch deterrents were installed above the conductors on all nest pylons and on high-risk pylons up to 10 structures on both sides of each nest tower; and (iii) the welfare of the eagles was monitored before and after management. In this way, line faulting was reduced on actively managed lines by > 75%, with no obvious deleterious effects on the eagle population. The study revealed that: (i) power lines can support substantial breeding populations of threatened large raptors, (ii) these birds can be a source of commercially significant line faulting, and (iii) nest relocations and perch deterrents are effective in reducing faulting without negatively impacting eagle populations.
Touring behind the lines: British soldiers in French towns and cities during the Great War
Authors: COWMAN KRISTA 
Published: May 2013

ABSTRACT:This article explores the importance that accessing urban life assumed for British soldiers stationed in France during World War I. Many who fought on the Western Front had never visited a foreign country before sailing to France. Drawing on contemporary letters and diaries and later memoirs, it considers how men responded to the new experiences they found in French towns and cities behind the lines. Through exploring activities from shopping and dining to cinema and prostitution, it argues that urban outings became critical to sustaining morale by offering opportunities to engage with civilian life on a reasonably regular basis.

AbstractIntroductionHealth care institutions constantly must be prepared for disaster response. However, there are deficiencies in the current level of preparedness. The aim of this study was to investigate the factors affecting the perception of health care workers (HCWs) towards individual and institutional preparedness for a disaster.MethodsA survey on disaster incident preparedness was conducted among doctors, nurses, and allied health workers over a period of two months in 2010. The survey investigated perceptions of disaster preparedness at the individual and institutional level. Responses were measured using a five-point Likert scale. The primary outcomes were factors affecting HCWs’ perception of institution and individual preparedness. Secondary outcomes were the proportions of staff willing to participate and to place importance on disaster response training and their knowledge of access to such training. Data was analyzed using descriptive statistics. Logistic regression was performed to determine the factors that influenced the HCWs’ perception of their individual and institutional readiness. Odd ratios (ORs) of such factors were reported with their 95% confidence intervals (CIs).ResultsOf 1700 HCWs, 1534 (90.2%) completed the survey. 75.3% (1155/1534) felt that the institution was ready for a disaster incident, but only 36.4% (558/1534) felt that they (as individuals) were prepared. Some important factors associated with a positive perception of institution preparedness were leadership preparedness (OR = 13.19; 95% CI, 9.93-17.51), peer preparedness (OR = 6.11; 95% CI, 4.27-8.73) and availability of training opportunities (OR = 4.76; 95% CI, 3.65-6.22). Some important factors associated with a positive perception of individual preparedness were prior experience in disaster response (OR = 2.80; 95% CI, 1.99-3.93), institution preparedness (OR = 3.71; 95% CI, 2.68-5.14), peer preparedness (OR = 3.49; 95% CI, 2.75-4.26), previous training in disaster response (OR = 3.48; 95% CI, 2.76-4.39) and family support (OR = 3.22; 95% CI, 2.54-4.07). Most (80.7%, 1238/1534) were willing to participate in future disaster incident response training, while 74.5% (1143/1534) felt that being able to respond to a disaster incident constitutes part of their professional competency. However, only 27.8% (426/1534) knew how to access these training opportunities.ConclusionsThis study demonstrated that HCWs fare poorly in their perception of their individual preparedness. Important factors that might contribute to improving this perception at the individual and institution level have been identified. These factors could guide the review and implementation of future disaster incident response training in health care institutions.LimGH,LimBL,VasuA.Survey of factors affecting health care workers’ perception towards institutional and individual disaster preparedness.Prehosp Disaster Med.2013;28(4):1-6.

AbstractObjectiveTo evaluate the use of an administered eighty-item FFQ to assess nutrient intake and diet quality in 3-year-old children.DesignFrequency of consumption and portion size of the foods listed on the FFQ during the 3 months preceding the interview were reported by the child's main caregiver; after the interview a 2 d prospective food diary (FD) was completed on behalf of the child. Nutrient intakes from the FFQ and FD were estimated using UK food composition data. Diet quality was assessed from the FFQ and FD according to the child's scores for a principal component analysis-defined dietary pattern (‘prudent’ pattern), characterised by high consumption of fruit, vegetables, water and wholemeal cereals.SettingSouthampton, UK.SubjectsChildren (n892) aged 3 years in the Southampton Women's Survey.ResultsIntakes of all nutrients assessed by the FFQ were higher than FD estimates, but there was reasonable agreement in terms of ranking of children (range of Spearman rank correlations for energy-adjusted nutrient intakes,rs= 0·41 to 0·59). Prudent diet scores estimated from the FFQ and FD were highly correlated (r= 0·72). Some family and child characteristics appeared to influence the ability of the FFQ to rank children, most notably the number of child's meals eaten away from home.ConclusionsThe FFQ provides useful information to allow ranking of children at this age with respect to nutrient intake and quality of diet, but may overestimate absolute intakes. Dietary studies of young children need to consider family and child characteristics that may impact on reporting error associated with an FFQ.
Effects of salt labelling and repeated in-home consumption on long-term liking of reduced-salt soups

AbstractObjectiveThe present study investigated the impact of salt labelling and repeated in-home consumption on liking of reduced-salt soups.DesignParticipants received a chicken noodle soup to be consumed twice weekly at home for 5 weeks. Three soups were included: (i) regular-salt soup as available on the market; (ii) 22 %-reduced-salt soup; and (iii) 32 %-reduced-salt soup. The soups were tasted blind or with the label: ‘same great taste, less salt and more herbs’. In total, there were six experimental groups. All groups received the same soup over the whole period. Desire and liking were measured at each time of consumption.SettingIn-home and central location test.SubjectsFrench consumers (n 646).ResultsThere was no significant difference in liking between the three soups when consumed at home, whereas the reduced-salt soups were less liked than the regular-salt soup in the central location test. Labelling did not boost liking scores, which is probably explained by the fact that all soups were similarly liked when eaten at home.ConclusionsThe surprising results of the present study in France suggest that a salt reduction of up to 32 % in a chicken noodle soup did not affect long-term liking score as assessed by consumers at home. In addition, initial liking measured at the central location was not predictive of liking after repeated in-home consumption. How far we can go in reducing salt in other products without compromising product quality, and how this impacts consumers’ choice behaviour and in turn table salt use at home, are still unanswered questions.
In SituStudy of Live Specimens in an Environmental Scanning Electron Microscope
Authors: Tihlaříková Eva , Neděla Vilém , Shiojiri Makoto 
Published: May 2013

AbstractIn this paper we introduce new methodology for the observation of living biological samples in an environmental scanning electron microscope (ESEM). The methodology is based on an unconventional initiation procedure for ESEM chamber pumping, free from purge–flood cycles, and on the ability to control thermodynamic processes close to the sample. The gradual and gentle change of the working environment from air to water vapor enables the study of not only living samples in dynamicin situexperiments and their manifestation of life (sample walking) but also its experimentally stimulated physiological reactions. Moreover, Monte Carlo simulations of primary electron beam energy losses in a water layer on the sample surface were studied; consequently, the influence of the water thickness on radiation, temperature, or chemical damage of the sample was considered.
A BRIDGE OVER TROUBLED URBAN WATERS
Authors: Hunter Marcus Anthony 
Published: May 2013

AbstractGenerating new understandings of the contributions of W. E. B. Du Bois'sThe Philadelphia Negro(1899) for sociology and social science more generally, this article posits that the urban analysis provided in the book demonstrates how interwoven cultural and economic factors undergird the social organization of urban communities more so than any pragmatic economic pattern or logic. It is the interwoven nature of these factors (defined in this article as the counterintuitive economic logics of the study) that have been insufficiently acknowledged in recent decades of social scientific urban studies research. Exploring the interwoven nature of cultural and economic factors in the sustenance of Philadelphia's Black Seventh Ward, this article suggests that the agency of African Americans is a critical, yet undervalued, aspect of their urban living. This article situates W. E. B. Du Bois as the first of some later voices (mostly within urban ethnography) that offer a corrective and alternative to urban spatial conceptual frameworks that did not and do not fully account for the persistent influence of race and the agency of racial minorities on the landscape of American cities.
Toward highly scaled AlN/GaN-on-Silicon devices for millimeter wave applications

Published: May 2013

In this work, the possibility of achieving GaN-on-Si devices for millimeter wave applications operating at high bias is demonstrated. It is shown that highly scaled AlN/GaN-on-Si double heterostructure enables us to significantly improve electron confinement under high electric field as compared to single heterostructure while delivering high carrier density (>2 × 1013 cm−2). Subsequently, trapping effects can be minimized resulting in the highest GaN-on-Si output power density up to 40 GHz and at a drain bias of 15 V together with a record fmax close to 200 GHz. At higher bias, infrared camera analysis clearly shows that these devices are mainly limited by self-heating effects. Furthermore, low noise figure has been assessed on this heterostructure, promising integration of cost effective low noise and high power millimeter wave amplifiers.

Published: May 2013

The design and characterization of a new broadband small patch antenna, based on an innovative magneto-dielectric material and suitable for wearable applications at 868 MHz, is presented. To reduce antenna dimensions, while preserving its radiation and matching performance, a barium-strontium hexaferrite Ba0.75Sr0.25Fe12O19 has been synthesized as the antenna substrate to achieve magnetic permeability double than vacuum in the band of interest. First material realization is characterized and dispersive permittivity and permeability behaviors are included in the design of a small patch antenna with a shorting-plate. A button-size realization is obtained and its suitability for wearable applications is numerically and experimentally demonstrated on body with and without the presence of conductive shielding. Very good agreement with measurements is demonstrated for both matching and radiation performance of the antenna.

AbstractAlthough the recruitment of fibroblasts to areas of injury is critical for wound healing, their subsequent apoptosis is necessary in order to prevent excessive scarring. Fibroproliferative diseases, such as pulmonary fibrosis, are often characterized by fibroblast resistance to apoptosis, but the mechanism(s) for this resistance remains elusive. Here, we employed a murine model of pulmonary fibrosis and cells from patients with idiopathic pulmonary fibrosis (IPF) to explore epigenetic mechanisms that may be responsible for the decreased expression of Fas, a cell surface death receptor whose expression has been observed to be decreased in pulmonary fibrosis. Murine pulmonary fibrosis was elicited by intratracheal injection of bleomycin. Fibroblasts cultured from bleomycin-treated mice exhibited decreased Fas expression and resistance to Fas-mediated apoptosis compared with cells from saline-treated control mice. Although there were no differences in DNA methylation, the Fas promoter in fibroblasts from bleomycin-treated mice exhibited decreased histone acetylation and increased histone 3 lysine 9 trimethylation (H3K9Me3). This was associated with increased histone deacetylase (HDAC)-2 and HDAC4 expression. Treatment with HDAC inhibitors increased Fas expression and restored susceptibility to Fas-mediated apoptosis. Fibroblasts from patients with IPF likewise exhibited decreased histone acetylation and increased H3K9Me3 at the Fas promoter and increased their expression of Fas in the presence of an HDAC inhibitor. These findings demonstrate the critical role of histone modifications in the development of fibroblast resistance to apoptosis in both a murine model and in patients with pulmonary fibrosis and suggest novel approaches to therapy for progressive fibroproliferative disorders.
Gene invasion in distant eukaryotic lineages: discovery of mutually exclusive genetic elements reveals marine biodiversity

Abstract
Inteins are rare, translated genetic parasites mainly found in bacteria and archaea, while spliceosomal introns are distinctly eukaryotic features abundant in most nuclear genomes. Using targeted metagenomics, we discovered an intein in an Atlantic population of the photosynthetic eukaryote, Bathycoccus, harbored by the essential spliceosomal protein PRP8 (processing factor 8 protein). Although previously thought exclusive to fungi, we also identified PRP8 inteins in parasitic (Capsaspora) and predatory (Salpingoeca) protists. Most new PRP8 inteins were at novel insertion sites that, surprisingly, were not in the most conserved regions of the gene. Evolutionarily, Dikarya fungal inteins at PRP8 insertion site a appeared more related to the Bathycoccus intein at a unique insertion site, than to other fungal and opisthokont inteins. Strikingly, independent analyses of Pacific and Atlantic samples revealed an intron at the same codon as the Bathycoccus PRP8 intein. The two elements are mutually exclusive and neither was found in cultured Bathycoccus or other picoprasinophyte genomes. Thus, wild Bathycoccus contain one of few non-fungal eukaryotic inteins known and a rare polymorphic intron. Our data indicate at least two Bathycoccus ecotypes exist, associated respectively with oceanic or mesotrophic environments. We hypothesize that intein propagation is facilitated by marine viruses; and, while intron gain is still poorly understood, presence of a spliceosomal intron where a locus lacks an intein raises the possibility of new, intein-primed mechanisms for intron gain. The discovery of nucleus-encoded inteins and associated sequence polymorphisms in uncultivated marine eukaryotes highlights their diversity and reveals potential sexual boundaries between populations indistinguishable by common marker genes.
