The impact of a national program to provide free mammograms to low‐income, uninsured women on breast cancer mortality rates
Authors: Howard David H. , Ekwueme Donatus U. , Gardner James G. , Tangka Florence K. , Li Chunyu , Miller Jacqueline W.
Published: June 2010

BACKGROUND:

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides free or low‐cost breast and cervical cancer screening to low‐income, uninsured or underinsured women. The authors analyzed the impact of the NBCCEDP on breast cancer mortality rates.

METHODS:

The data consisted of observations for each state and year for the period from 1990 through 2004. The outcome variable was the breast cancer mortality rate for women ages 40 to 64 years. Independent variables included the proportion of women ages 40 to 64 years screened under NBCCEDP. The impact of screening intensity was estimated using least‐squares regression with state and year fixed effects.

RESULTS:

In 2004, 1.2% of women ages 40 to 64 years were screened under NBCCEDP. The NBCCEDP screening rate was related significantly and negatively to breast cancer mortality in the same year. Results indicate that, for every 1000 women screened, there were 0.6 fewer deaths because of breast cancer among women ages 40 to 64 years. Changes in screening rates were unrelated to breast cancer mortality ≥2 years in the future.

CONCLUSIONS:

In the current study, there was some evidence suggesting that the NBCCEDP led to a reduction in breast cancer mortality rates. However, the failure to detect an impact of screening on mortality rates in subsequent years suggests that caution is needed in interpreting these results as strong evidence in favor of the effectiveness of the NBCCEDP in reducing breast cancer mortality.

The cover picture highlights a few of the fine collection of articles assembled in this Cluster Issue on f elements, based on presentations at the 7th International Conference on f Elements held in Cologne (23–27 August 2009). The individual graphics making up the composite design are set against a background depicting Cologne, with the Cathedral barely visible in the mist. Just as the sun clears the mist to bring about a beautiful view, the knowledge that stems from the f elements is far reaching. The diversity of f‐element chemistry is reflected in the contributions shown on the cover. The solid‐state chemistry of Lu–Bi–Te clusters is highlighted by J. D. Corbett et al. (p. 2620ff), and the importance of ionic liquids in f‐element chemistry, as illustrated by the response of the lanthanide ionic liquid to an externally applied magnetic field, is reviewed by A. V. Mudring et al. (p. 2569ff). The binding mode in rare‐earth metal complexes with donor‐functionalised hydroxylaminato ligands is featured by N. W. Mitzel et al. (p. 2774ff), and the luminescence behaviour of LaVO4:Eu nanocrystals is revealed by C.‐H. Yan et al. (p. 2626ff). A hearty thanks to the authors for their valuable contributions to the cover.
Analysis of low‐molecular mass aldehydes in drinking waters through capillary electrophoresis with laser‐induced fluorescence detection
Authors: Baños Clara Eugenia , Silva Manuel
Published: June 2010

The potential of CZE with LIF detection in the separation and determination of low‐molecular mass aldehydes involving precolumn derivatization with fluorescein 5‐thiosemicarbazide was investigated. Different variables that affect derivatization (pH, fluorescein 5‐thiosemicarbazide concentration, time and temperature) and separation (pH and concentration of the BGE, kind and concentration of surfactants at levels higher and lower than CMC, and applied voltage) were studied. The separation was conducted within 16 min by using borate buffer (60 mM; pH 10) with 10 μM polyethylene glycol tert‐octylphenyl ether as modifier. Good linearity relationships (correlation coefficients ranged from 0.9978 to 0.9994 for aldehydes) were obtained between the peak areas and concentration of the analytes (0.5–100 μg/L). The LODs for aldehydes were achieved at submicrogram‐per‐liter level (0.15–0.35 μg/L), which indicated that the proposed method surpassed other electrophoretric alternatives in terms of LOD, in many cases even at ca. 1000‐fold. The inter‐day precision (RSD, %) of the aldehydes ranged from 5.2 to 8.3%. Finally, the method was successfully applied to bottled drinking‐water samples, and the aldehydes were readily detected at 0.6–4.4 μg/L levels with average recoveries ranging from 99.1 to 103.5%.
Clinicians' conceptualizations of comorbid cases: a test of additive versus nonadditive models
Authors: Keeley Jared , Blashfield Roger K.
Published: June 2010

Comorbidity in psychopathology is a common phenomenon. However, little is known about the way in which clinicians think about comorbid cases. The Diagnostic and Statistical Manual, Fourth Edition, Text Revision (DSM‐IV‐TR; American Psychiatric Association, 2000) implies an additive model of concept combination, but studies of human cognition find that individuals often combine concepts in nonadditive ways. In this study, 70 clinicians listed symptoms for three disorders and their combinations. Participants produced nonadditive descriptions, termed overextensions, at significant rates. These results challenge the utility of the implicit additive model of the current DSM. © 2010 Wiley Periodicals, Inc. J Clin Psychol 66:1–10, 2010.
Poverty and disability: A vicious circle? Evidence from Afghanistan and Zambia
Authors: Trani Jean‐Francois , Loeb Mitchell
Published: June 2010

Disability and poverty have a complex and interdependent relationship. It is commonly understood that persons with disabilities are more likely to be poor and that poverty may contribute to sustaining disability. This interdependency is revealed not only through an examination of poverty in terms of income but also on a broader scale through other poverty related dimensions. Just how robust is this link? This paper compares data collected from household surveys in Afghanistan and Zambia, and explores the potential link between multidimensional poverty and disability. We find evidence of lower access to health care, education and labour market for people with disabilities, whatever is the disability status, but poverty measured by an asset index is not statistically different between people with and without disabilities.

Optimizing [13N]N2 radiochemistry for nitrogen‐fixation in root nodules of legumes
Authors: Kasel Mirjam C. K. , Schueller Michael J. , Ferrieri Richard A.
Published: June 2010

Here we explored the conditions for synthesizing [13N]N2 in a state that is suitable for the administration to plant root nodules enabling studies of nitrogen fixation. [13N]N2 was prepared batchwise, starting with [13N]NO from the 16O(p,α)13N nuclear reaction on a liquid water target. [13N]NO was first reduced to [13N]NH3 using Devarda's alloy, and then the [13N]NH3 was oxidized to [13N]N2 by hypobromite using carrier‐added NH4Cl. The amounts of carrier NH4Cl and hypobromite were varied to determine the effects these parameters had on the radiochemical yield, and on the radiotracer specific activity. As expected, increasing the amount of carrier NH4Cl improved the radiochemical yield. Unexpectedly, increasing the amount of excess hypobromite from 1.6‐fold to 6‐fold molar equivalents (relative to NH4Cl) improved the radiochemical yield and radiotracer specific activity under all conditions of carrier NH4Cl. As a comparison, we measured [13N]N2 specific activity derived from in‐target production based on a 50 µA min irradiation driving the 14N(p,pn)13N reaction on a gaseous N2 target. The ‘wet’ radiochemistry approach afforded two advantages over the in‐target approach with a ∼600‐fold improvement in specific activity, and the ability to collect the tracer in a small volume of gas (∼20 mL at STP).

Effects of perennial fodder crops on soil structure in agricultural headlands
Authors: Kautz Timo , Stumm Christoph , Kösters Raimund , Köpke Ulrich
Published: June 2010

In agricultural headlands, rooting and yield of crops may be limited because of soil‐structure changes as a consequence of multiple passes of turning machinery. We hypothesized that perennial forage crops can substantially alter soil structure in agricultural headlands. On one experimental field and two commercial farms on Haplic Luvisols from respectively loess and sandy loess in the Lower Rhine Bay (Germany), we investigated how 4 y of continuously grown grass/clover or alfalfa affected soil structure and the performance of subsequent spring wheat. Compared with a crop rotation with annual plowing to 30 cm soil depth, perennial forage crops led to increased soil C content (+1.3% to +22.8%) and N content (+4.2% to +15.1%), higher densities of medium and coarse biopores at a depth of 35 cm, more large water‐stable soil macroaggregates, higher biomass and abundance of anecic earthworms, and higher grain yield and grain protein content of spring wheat grown as the following crop. Root‐length density of spring wheat in the subsoil was not affected by the preceding perennial fodder crops in two of the three field trials. We concluded that besides increasing N input to the soil, perennial cropping of grass/clover or alfalfa has effects on soil structure that may substantially reduce yield losses in agricultural headlands.
Effects of rainfall pattern on carbon and nitrogen dynamics in soil amended with biogas slurry and composted cattle manure
Authors: Sänger Anja , Geisseler Daniel , Ludwig Bernard
Published: June 2010

Soil moisture affects the degradation of organic fertilizers in soils considerably, but less is known about the importance of rainfall pattern on the turnover of C and N. The objective of this study was to determine the effects of different rainfall patterns on C and N dynamics in soil amended with either biogas slurry (BS) or composted cattle manure (CM). Undisturbed soil cores without (control) or with BS or CM, which were incorporated at a rate of 100 kg N ha–1, were incubated for 140 d at 13.5°C. Irrigation treatments were (1) continuous irrigation (cont_irr; 3 mm d–1); (2) partial drying and stronger irrigation (part_dry; no irrigation for 3 weeks, 1 week with 13.5 mm d–1), and (3) periodic heavy rainfall (hvy_rain; 24 mm d–1 every 3 weeks for 1 d and 2 mm d–1 for the other days). The average irrigation was 3 mm d–1 in each treatment. Cumulative emissions of CO2 and N2O from soils amended with BS were 92.8 g CO2‐C m–2 and 162.4 mg N2O‐N m–2, respectively, whereas emissions from soils amended with CM were 87.8 g CO2‐C m–2 and only 38.9 mg N2O‐N m–2. While both organic fertilizers significantly increased CO2 production compared to the control, N2O emissions were only significantly increased in the BS‐amended soil. Under the conditions of the experiment, the rainfall pattern affected the temporal production of CO2 and N2O, but not the cumulative emissions. Cumulative NO$ _3^- $ leaching was highest in the BS‐amended soils (9.2 g NO$ _3^- $‐N m–2) followed by the CM‐amended soil (6.1 g NO$ _3^- $‐N m–2) and lowest in the control (4.7 g NO$ _3^- $‐N m–2). Nitrate leaching was also independent of the rainfall pattern. Our study shows that rainfall pattern may not affect CO2 and N2O emissions and NO$ _3^- $ leaching markedly provided that the soil does not completely dry out.
Significance of fruit transpiration on calcium nutrition in developing apricot fruit
Authors: Montanaro Giuseppe , Dichio Bartolomeo , Xiloyannis Cristos
Published: June 2010

The first objective of this study was to search for a possible correlation between accumulation of calcium (Ca), potassium (K), and magnesium (Mg) and fruit transpiration in developing apricot (Prunus armeniaca L.) fruit. Secondly, the work aimed to determine the significance of transpirational flux on Ca nutrition. We hypothesized that if the fruit transpiration is the determining factor of Ca accumulation (phloem‐immobile element) then the import of Ca would be suppressed by restriction of fruit water loss, while the import of phloem‐mobile nutrients (i.e., K and Mg) would not be. To test this hypothesis, the seasonal changes of transpiration and of Ca, K, and Mg concentration/accumulation were assessed in fruits left to naturally transpire or under restricted transpiration (bagged fruits). Fruit transpiration was measured on detached fruits using a portable gas‐exchange equipment (ADC‐LCA4, ADC BioScientific Ltd, Hoddesdon, England). Results demonstrated that 83% of total fruit Ca content was gained within the first 4 weeks after fruit‐set, and that Ca import ceased concomitantly to a reduction of transpiration. In spite of the limitation of fruit transpiration, Ca entered the nontranspiring fruits, and its concentration was about 45% of that in control fruits suggesting that other factor(s) operated for Ca accumulation. This study provides the evidence that fruit transpiration accounted for 55% of total Ca that entered a fruit. We conclude that optimal soil Ca availability and apportioning to the fruit during the early 4 weeks of growth are essential to sustain the fruit demand of this nutrient and that some cultural practices (e.g., summer pruning, irrigation) should be tested as possible tools to improve fruit Ca nutrition via increasing fruit transpiration.
Exposure to cigarette smoke condensate reduces calcium activated chloride channel transport in primary sinonasal epithelial cultures
Authors: Virgin Frank W. , Azbell Christopher , Schuster Daniel , Sunde Jumin , Zhang Shaoyan , Sorscher Eric J. , Woodworth Bradford A.
Published: June 2010

Objectives/Hypothesis:

The cystic fibrosis transmembrane conductance regulator (CFTR) serves as a predominant Cl− transport conduit in airway epithelium and is inhibited by cigarette smoke in vitro and in vivo. Activation of secondary Cl− transport pathways through calcium‐activated Cl− channels (CaCC) has been postulated as a mechanism to bypass defects in CFTR‐mediated transport. Because it is not known whether CaCCs are also inhibited by tobacco exposure, the current study was designed to investigate the effect of cigarette smoke condensate (CSC) on CaCC transport.

Study Design:

In vitro study.

Methods:

Well‐characterized primary murine nasal septal epithelial (MNSE) and human sinonasal epithelial (HSNE) cultures were exposed to CSC in Ussing chambers. We monitored CaCC short‐circuit current through stimulation of P2Y purinergic receptors with uridine triphosphate or adenosine triphosphate and selective inhibition of the CFTR‐dependent secretory pathway. Characterization of CaCC current was also accomplished in primary airway cells derived from transgenic CFTR−/− (knockout) murine models.

Results:

Change in CaCC‐mediated current (ΔISC representing transepithelial Ca‐mediated Cl− secretion in μA/cm2) was significantly decreased in CSC‐exposed wild type MNSE when compared to controls (32.8 ± 4.6 vs. 47.5 ± 2.3; respectively; P < .02). A similar effect was demonstrated in CFTR−/− MNSE cultures (33.4 ± 2.8 vs. 38.6 ± 2.0; P < .05>. HSNE cultures also had a significant reduction in ISC (16.1 ± 0.6 vs. 22.7 ± 0; P = .008).

Conclusions:

CSC affects multiple pathways fundamental to airway ion transport, including both cyclic adenosine monophosphate and calcium activated Cl− transport. Inhibition of Cl− transport may contribute to common diseases of the airways, such as chronic rhinosinusitis and chronic obstructive pulmonary disease. Laryngoscope, 2010
Management and outcomes of facial paralysis from intratemporal blunt trauma: A systematic review
Authors: Nash John J. , Friedland David R. , Boorsma Keren J. , Rhee John S.
Published: June 2010

Objectives/Hypothesis:

To systematically review the existing literature on outcomes and management of facial paralysis resulting from intratemporal blunt trauma.

Study Design:

Systematic review of the literature.

Methods:

Thirty‐five articles met our inclusion criteria. Outcome variables analyzed included severity of paralysis, time of onset of paralysis, surgical or nonsurgical management, steroid use, and final facial nerve function.

Results:

All studies were classified as level 4 evidence as defined by the Oxford Centre for Evidence‐Based Medicine. There was marked variation in the quality of the studies with inconsistent outcome measures, diagnostic testing, and follow‐up, thus ruling out a formal meta‐analysis. In an exploratory pooling of data, 612 cases had sufficient follow‐up and facial movement grading for some evaluation of trends. In 189 patients who were followed observationally, 66% achieved an outcome equivalent to House‐Brackmann (HB) I, 25% achieving HB II‐V, and two patients an HB VI score. Among 83 patients treated with steroids, 67% achieved HB I, 30% HB II‐V, and no patients with HB VI. In 340 patients treated surgically, 23% achieved HB I postoperatively, 58% were graded as HB II‐V, and 9% with HB grade VI postoperatively. No patient presenting with partial paralysis had an HB VI outcome.

Conclusions:

The role of surgery versus nonsurgical interventions for this clinical entity remains inconclusive. Level 4 evidence studies predominate and are further hindered by poor description of outcome measures and incomplete data reporting. Exploratory pooling of data without formal meta‐analysis suggests the need to compare any intervention to the natural course of healing, which overall appears to be favorable. Laryngoscope, 2010
Simulated reflux decreases vocal fold epithelial barrier resistance
Authors: Erickson Elizabeth , Sivasankar Mahalakshmi
Published: June 2010

Objectives/Hypothesis:

The vocal fold epithelium provides a barrier to the entry of inhaled and systemic challenges. However, the location of the epithelium makes it vulnerable to damage. Past research suggests, but does not directly demonstrate, that exposure to gastric reflux adversely affects the function of the epithelial barrier. Understanding the nature of reflux‐induced epithelial barrier dysfunction is necessary to better recognize the mechanisms for vocal fold susceptibility to this disease. Therefore, we examined the effects of physiologically relevant reflux challenges on vocal fold transepithelial resistance and gross epithelial and subepithelial appearance.

Study Design:

Ex vivo, mixed design with between‐group and repeated‐measures analyses.

Methods:

Healthy, native porcine vocal folds (N = 52) were exposed to physiologically relevant acidic pepsin, acid‐only, or pepsin‐only challenges and examined with electrophysiology and light microscopy. For all challenges, vocal folds exposed to a neutral pH served as control.

Results:

Acidic pepsin and acid‐only challenges, but not pepsin‐only or control challenges significantly reduced transepithelial resistance within 30 minutes. Reductions in transepithelial resistance were irreversible. Challenge exposure produced minimal gross changes in vocal fold epithelial or subepithelial appearance as evidenced by light microscopy.

Conclusions:

These findings demonstrate that acidic environments characteristic of gastric reflux compromise epithelial barrier function without gross structural changes. In healthy, native vocal folds, reductions in transepithelial resistance could reflect reflux‐related epithelial disruption. These results might guide the development of pharmacologic and therapeutic recommendations for patients with reflux, such as continued acid‐suppression therapy and patient antireflux behavioral education.

A systematic analysis of septal deviation associated with rhinosinusitis
Authors: Orlandi Richard R.
Published: June 2010

Objectives/Hypothesis:

Rhinosinusitis might have many etiologies that lead to a common presentation of inflammation and impaired mucociliary clearance. Anatomic factors were once thought to play a large role in the pathogenesis of rhinosinusitis, and septal deviation was examined in multiple studies with conflicting results. With the more recent appreciation that the development of rhinosinusitis is likely multifactorial, it is appropriate to re‐examine possible anatomic etiologies. A systematic analysis of septal deviation and rhinosinusitis was therefore performed to better define this association and describe possible etiologic mechanisms. Examination of a large sample, accomplished through systematically identifying and combining previous studies, may compensate for the several shortcomings of these separate analyses. A systematic analysis was therefore performed to answer the question, is septal deviation associated with rhinosinusitis?

Study Design:

Systematic analysis of previously published studies.

Methods:

Following a structured literature search, articles examining the association of septal deviation and rhinosinusitis were analyzed quantitatively and qualitatively. Based on the quantitative results, a septal deviation angle (SDA) cutoff of 10° was chosen for distinguishing positive from negative for septal deviation in the qualitative analysis.

Results:

Of over 300 references initially identified, 13 articles comprised the basis of this review. Increasing angles of septal deviation were associated with increasing prevalence of rhinosinusitis in multiple studies. Combining the results of five previous studies on this subject demonstrated significant association of septal deviation and rhinosinusitis (P = .0004, χ2 analysis). The clinical effect was found, however, to be modest with an odds ratio of 1.47. Interestingly, in all studies that examined the laterality of rhinosinusitis associated with septal deviation, inflammation was found bilaterally. Based on the data from this analysis, it appears that many of the previous analyses were insufficiently powered to detect an association between rhinosinusitis and septal deviation. Others failed to find an association by examining subjects with small SDAs.

Conclusions:

Septal deviation is associated with an increased prevalence of rhinosinusitis, although the impact of this anatomic anomaly is limited. It appears to be one of many possible factors that might lead to the development of rhinosinusitis. Laryngoscope, 2010
Value of intracochlear electrically evoked auditory brainstem response after cochlear implantation in patients with narrow internal auditory canal
Authors: Song Mee Hyun , Bae Mi Ran , Kim Hee Nam , Lee Won‐Sang , Yang Won Sun , Choi Jae Young
Published: June 2010

Objectives/Hypothesis:

Cochlear implantation in patients with narrow internal auditory canal (IAC) can result in variable outcomes; however, preoperative evaluations have limitations in accurately predicting outcomes. In this study, we analyzed the outcomes of cochlear implantation in patients with narrow IAC and correlated the intracochlear electrically evoked auditory brainstem response (EABR) findings to postoperative performance to determine the prognostic significance of intracochlear EABR.

Study Design:

Retrospective case series at a tertiary hospital.

Methods:

Thirteen profoundly deaf patients with narrow IAC who received cochlear implantation from 2002 to 2008 were included in this study. Postoperative performance was evaluated after at least 12 months of follow‐up, and postoperative intracochlear EABR was measured to determine its correlation with outcome. The clinical significance of electrically evoked compound action potential (ECAP) was also analyzed.

Results:

Patients with narrow IAC showed postoperative auditory performances ranging from CAP 0 to 4 after cochlear implantation. Intracochlear EABR measured postoperatively demonstrated prognostic value in the prediction of long‐term outcomes, whereas ECAP measurements failed to show a significant correlation with outcome.

Conclusions:

Consistent with the advantages of intracochlear EABR over extracochlear EABR, this study demonstrates that intracochlear EABR has prognostic significance in predicting long‐term outcomes in patients with narrow IAC. Intracochlear EABR measured either intraoperatively or in the early postoperative period may play an important role in deciding whether to continue with auditory rehabilitation using a cochlear implant or to switch to an auditory brainstem implant so as not to miss the optimal timing for language development.

Tailored telescopic reconstruction of the bile duct in living donor liver transplantation
Authors: Kim Seong Hoon , Lee Kwang-Woong , Kim Young-Kyu , Cho Seong Yeon , Han Sung-Sik , Park Sang-Jae
Published: June 2010

Duct-to-duct reconstruction (DDR) of the bile duct has recently become the preferred choice in living donor liver transplantation (LDLT), but biliary complications still remain the most common cause of morbidity. We introduce our new technique of tailored telescopic reconstruction (TTR) of the bile duct for reducing bile duct complications in LDLT: the hilar plate covering the right and left hepatic ducts is bisected lengthwise through the right or left hepatic duct opening to make a funnel-shaped top, into which the donor hepatic duct is telescoped to match the recipient bile duct in size, and DDR is performed in the inner tissue of good vascular integrity of the recipient bile duct without redundancy. Forty-five consecutive LDLT procedures from January to August 2008 were analyzed through a comparison of 23 conventional duct-to-duct reconstructions (cDDRs) and 22 TTRs in bile duct anastomoses. At a mean follow-up of 19.5 months, the rates of overall biliary complications, leakage, and strictures were 43.5%, 26.1%, and 34.8%, respectively, for cDDR and 9.1%, 0%, and 9.1%, respectively, for TTR (P < 0.05 for each). In conclusion, TTR of the bile duct results in excellent outcomes with respect to minimization of biliary complications; thus, TTR can be recommended as a preferred method for biliary reconstruction in LDLT.

School outcomes in children registered in the studies for pediatric liver transplant (SPLIT) consortium
Authors: Gilmour Susan M. , Sorensen Lisa G. , Anand Ravinder , Yin Wanrong , Alonso Estella M.
Published: June 2010

School performance is an important aspect of functional outcomes for pediatric liver transplant (LT) recipients. This longitudinal analysis conducted through the Studies of Pediatric Liver Transplantation (SPLIT) research consortium examines several indicators of school function in these patients. A total of 39 centers participated in data collection using a semistructured questionnaire designed specifically for this study. The survey queried school attendance, performance and educational outcomes including the need for special educational services. Participants included 823 of 1133 (73%) eligible patients, mean age 11.34 ± 3.84 years, 53% female, median age at LT 4.6 (range 0.05-17.8) years, and mean interval from transplant was 5.42 ± 2.79. Overall, 34% of patients were receiving special educational services and 20% had repeated a grade, with older participants more likely to have been held back (P = 0.0007). Missing more than 10 days of school per year was reported by one-third of the group, with this level of absence being more common in older participants (P = 0.0024) and children with shorter intervals from LT (P < 0.0001). Multivariate analysis revealed the following factors were associated with the need for special educational services; type of immunosuppression at 6 months post-LT, cyclosporine A (odds ratio [OR] = 1.8, confidence interval [CI] = 1.1-3.1), or other (OR = 4.9, 95% CI = 1.4-17.6) versus tacrolimus, symptomatic cytomegalovirus infection within 6 months of liver transplantation (OR = 3.1, CI = 1.6-6.1), and pretransplant special educational services (OR = 22.5, CI = 8.6-58.4).

Authentic subcultural membership: Antecedents and consequences of authenticating acts and authoritative performances
Authors: Beverland Michael B. , Farrelly Francis , Quester Pascale G.
Published: June 2010

The postmodern consumer often finds authenticity in communities of consumption including those that are based around a focal brand. Two means through which authenticity can be achieved are an individual authenticating act or a collective authoritative performance. Using this dual lens, the contested nature of authenticity within subcultures is explored. Drawing on long, interpretive interviews with surfers, skaters, and snowboarders, it was found that the contested nature of authentic community membership is driven by different identity benefits, including flow and kinship. These two separate benefits lead members to engage different brand‐related cues when seeking an authentic brand partner. This paper advances the understanding of subcultural authenticity by identifying the diversity of identity goals sought from membership of consumption communities and by linking antecedents and outcomes of authenticity, and associated consumption behaviors. © 2010 Wiley Periodicals, Inc.

Published: June 2010

A new composite right/left‐handed (CRLH) resonant antenna with interdigital capacitors for a size reduction is proposed in this letter. This antenna consists of three sectional patches, two interdigital lines (capacitors) with a defected ground, and two shorting pins. A rectangular patch is split into three sections and each section is coupled with an interdigital line. When the proposed antenna is operated in the LH resonant mode, the antenna size is reduced by 33% and the antenna gain is increased by 7 dB as compared with one without defected ground structures. © 2010 Wiley Periodicals, Inc.

Measurement and modeling of interference for multiple antenna system
Authors: Ananthanarayanan Sai , Magleby Alyssa , Furse Cynthia
Published: June 2010

This article provides a detailed signal model (DSM) based on network theory to predict the multiantenna capacity in the presence of co‐ and adjacent channel interference.This model expands on previous channel models by including the simultaneous effects of interference, antenna matching, efficiency, directivity and polarization. Single and multiantenna interference are modeled using both a statistical channel model and a site‐specific 3D ray tracer. The network theory based DSM was obtained by adding antenna front end effects at both the transmitter and receiver to the channel models. This model was validated with measurements performed in two underground tunnels. The site‐specific model predicted the capacity to within 1 bit/sec/Hz of the measurements while the statistical model was within 1‐2 bits/sec/Hz except for a few locations. It was also observed that for small antenna spacing the conjugate match provides higher capacity than the self match. © 2010 Wiley Periodicals, Inc.

Published: June 2010

Design approach and characterization of an integrated oscillator switched by an optical power are discussed. The oscillator is driven into oscillation at a frequency of 4.9 GHz under a light excitation power upper than a threshold value of 40 mW at a wavelength of 800 nm. On‐off Keying modulation of the oscillator is performed with a digital optical power modulation allowing thus direct data transfer from optical to microwave carrier by photoconductivity. Illumination of the oscillator with optical pulses reveals the generation of short oscillations. The number of the generated signal periods depends on the optical power level and optical pulses width. © 2010 Wiley Periodicals, Inc.

Anfis models for the quasistatic analysis of coplanar strip line structures
Authors: Turkmen Mustafa , Yildiz Celal , Guney Kerim , Kaya Sabri
Published: June 2010

In this work, computer‐aided design models based on adaptive‐network‐based fuzzy inference system (ANFIS) for the quasistatic analysis of three different coplanar strip line structures are presented. These strip line structures are conventional coplanar strip lines, asymmetrical coplanar strip lines with infinitely wide strip, and asymmetrical coplanar strip lines with infinitely thick dielectric substrate. The design parameters of the proposed ANFIS models are optimally determined by using four different optimization algorithms, hybrid learning, simulated annealing, least‐squares, and genetic algorithm. When the performances of ANFIS models are compared with each other, the best results for training and test are obtained from the models trained with hybrid learning algorithm. There is a good agreement among the results of ANFIS models, quasistatic analysis, a full‐wave electromagnetic simulator IE3D, and experimental works realized in this study. © 2010 Wiley Periodicals, Inc.

The design and realization of a highly linear power amplifier module for a WiMAX/WiBro (802.16e) base station

Published: June 2010

We have designed and realized a highly linear power amplifier module (PAM) for a WiMAX/WiBro base station using a simple linearization method. To improve the linearity of the PAM, we use large‐signal intermodulation distortion (IMD) sweet spots, which are part of the inherent properties of power transistors. These IMD sweet spots are determined by the device technologies and the bias voltage. Our PAM consists of a drive stage and a power stage. Two amplifiers are used in the drive stage, a GaAs field effect transistor (GaAs FET) and a laterally diffused metal oxide semiconductor. The linearity of the PMA can be maximally improved by the large‐signal IMD sweet spots, which are tuned by the bias voltage of the GaAs FET at the signal power input of the drive stage. Using this method, the measured adjacent channel leakage ratio and power consumption efficiency of the PAM are improved by 2.9 dBc and 5.2%, respectively. The measured error vector magnitude of the PAM is only 1.45. © 2010 Wiley Periodicals, Inc.

Published: June 2010

We propose a new method of molecular transporters generations based on ant colony algorithm for molecular classification and storage applications.The transportation network of molecules via multitweezers inside the close system can be manipulated in the same way of ant colony algorithm relationship. In the proposed method, we assign that each of ants represents an individual tweezer. By using ant colony system, the random codes can be used to communicate between ants inside swarm with pheromone being formed the random network. The quantum state of transporter (individual ant) with different states and wavelengths is represented by the pheromone. In application, this proposal can be an alternative random networking which may be used for communication security, where the fast multiple access may be plausible. © 2010 Wiley Periodicals, Inc.

Develop CPW‐FED monopole broadband implantable antennas on the high dielectric constant ceramic substrates
Authors: Chien Tsung‐Fu , Yang Hung‐Chi , Cheng Chien‐Min , Luo Ching‐Hsing
Published: June 2010

A compact broadband planar monopole antenna fed by coplanar waveguide is developed and screen‐printed on the high dielectric constant microwave dielectric ceramic substrate for the applications of implanted biotelemetry. Biocompatible ceramic materials are selected for substrate (MgTa1.5Nb0.5O6, εr = 28) and superstrate (Al2O3, εr = 9.8). Additionally, for protecting from the tissue erosion, the metal parts (the body of the implanted antenna) are screen printed on a MgTa1.5Nb0.5O6 ceramic substrate and covered by a Al2O3 ceramic superstrate. Because the inductive loading effect generated by the rectangular type meander and the use of high dielectric constant ceramics, both size miniaturization and bandwidth enhancement can be achieved. The measured S11 of the proposed antenna in lossy emulated tissue is −43 dB, and the bandwidth of this proposed antenna can be improved to 100 MHz (351–461 MHz), which it is wide enough for the applications of modern MICS band (402–405 MHz) and ISM band (433–435 MHz). © 2010 Wiley Periodicals, Inc.

An 18.85 mW 20–29 GHz wideband CMOS low‐noise amplifier with 3.85 ± 0.25 dB noise figure and 18.1 ± 1.9 dB gain
Authors: Chiu Yi‐Ting , Lin Yo‐Sheng , Chang Jin‐Fa
Published: June 2010

A 20–29 GHz wideband CMOS low‐noise amplifier (LNA) with flat and low noise figure (NF), flat and high‐gain (S21), and excellent phase linearity property (group‐delay‐variation is only ±22.6 ps across the whole band) is demonstrated.To achieve flat and low NF, the size, layout, and bias of the input transistor were first optimized for minimum NF, and then the inductance of the input inductors was tuned to obtain a slightly under‐damped (flat) NF frequency response. In addition, to achieve flat and high S21 and small group‐delay‐variation, the inductive‐peaking technique was adopted in the current‐reused stage for bandwidth enhancement. The LNA consumed 18.85 mW power and achieved flat and low NF of 3.85 ± 0.25 dB, and flat and high S21 of 18.1 ± 1.9 dB over the 20–29 GHz band of interest. These are the best NF and S21 performances ever reported for a 21.65–26.65 GHz or a 22–29 GHz wideband CMOS LNA. © 2010 Wiley Periodicals, Inc.

Published: June 2010

This article presents a novel ultra‐wideband bandpass filter with controllable notched bands, compact size, and relaxed fabrication requirements.Its implementation is based on a rectangular slot ring resonator with an embedded S‐shaped slotline. The behavior of the rectangular slot ring resonator is characterized and subsequently adopted to build the wide passband. The notched band necessary for rejecting wireless local‐area network (WLAN) signals is implemented by the S‐shaped slotline. A prototype filter is implemented based on the proposed structure and good agreement is found between simulations and measurements. © 2010 Wiley Periodicals, Inc.
