Authors: Metcalf A.J. , Quinlan F. , Fortier T.M. , Diddams S.A. , Weiner A.M. 
Published: September 2015

The low timing jitter properties of a tunable single‐pass optoelectronic frequency comb generator is investigated. The scheme is flexible in that both the repetition rate and centre frequency can be continuously tuned. When operated with 10 GHz comb spacing, the integrated residual pulse‐to‐pulse timing jitter is 11.35 fs (1 Hz–10 MHz) with no feedback stabilisation. The corresponding phase noise at 1 Hz offset from the photodetected 10 GHz carrier is −100 dBc/Hz.

Authors: Pa P. , Larimore Z. , Parsons P. , Mirotznik M. 
Published: September 2015

A low‐profile antenna that includes an integrated artificial magnetic conducting (AMC) ground plane is presented and is fully fabricated using multi‐material additive manufacturing. It is shown that combining standard fused deposition modelling with conductive micro‐dispensing printing enable one to realise mechanically robust antenna systems that contain spatially variable dielectric properties and intricate three‐dimensional conducting networks. To illustrate this capability, a low‐profile antenna is designed, fabricated, and experimentally validated, consisting of a standard 2.6 GHz half wavelength printed dipole, balun, and AMC ground plane.

Authors: Johnson A.M. , Landecker T.L. , Johnson T. , Veidt B.G. , Du X. 
Published: September 2015

A new technique for exciting the TE11 mode in a number of concentric coaxial waveguides is described. The excitation network is log‐periodic and is designed to integrate a frequency multiplexing structure together with suppression of higher order modes (TE21 and TE31). The excitation network enables the implementation of very wide band nested coaxial feeds for reflector antennas where multiple waveguides are fed from a common input port. An excitation network providing continuous coverage over a 1–8 GHz frequency range was built and tested in a three‐band coaxial waveguide feed.

Published: September 2015

This study presents an ideal synchronous buck current regulator for variety of light‐emitting diode (LED) loads from wide input voltage range. By using high‐side power switch matched sense, the regulator maintains high current accuracy and high system efficiency. The adjustable current sense threshold provides a full‐range analogue dimming and the fast output enable/disable function allows for high‐frequency pulse‐width modulation (PWM) dimming. In addition, the two dimming methods are easy to implement and have highly linear range. An adaptive off‐time control is adopted to regulate an accurate constant current for its fast response and no need for control loop compensation, while its disadvantage of variation of switching frequency is overcome. The proposed circuit has been fabricated with 0.35 μm 40 V bipolar‐CMOS‐DMOS (BCD) process successfully. The experimental results confirm that the LED driver can operate within 6–40 V input voltage, and can drive a 1–10 output series connected LEDs. The switching frequency is fixed at 500 kHz with a variation of ±2%. The measured system peak efficiency is up to 95% at 1 A LED current and 10 V output voltage. The settling time at the PWM rising edge is <3.5 μs which is well beneficial for fast PWM dimming.

Study Design Retrospective study. Objective Symptomatic scoliosis can be a source of severe pain and disability. When nonoperative treatments fail, spine fusion is considered as an effective procedure in scoliosis management. The purpose of this study was to evaluate the trends of patients with scoliosis undergoing posterior long segment fusion (PLSF) with and without recombinant human bone morphogenetic protein 2 (rhBMP-2). Methods Patients within the orthopedic subset of Medicare database undergoing PLSF from 2005 to 2011 were identified using the PearlDiver Patient Records Database. Both diagnosis and procedural International Classification of Diseases, ninth edition and Current Procedural Terminology codes were used. The year of procedure, age, sex, region, and rhBMP-2 use were recorded. Results In total, 1,265,591 patients with scoliosis were identified with 29,787 PLSF surgeries between 2005 and 2011. The incidence of PLSF procedures increased gradually from 2005 to 2009, decreased in 2010 ( p < 0 0.01), and grew again in 2011. Patients over age 84 years had the highest incidence of PLSF. The lowest incidence of the procedures was in the Northeast, 5.96 per 100,000 patients. Sex differences were observed with a male-to-female ratio of 0.40 ( p < 0.01). The use of rhBMP-2 for PLSF increased steadily from 2005 to 2009; the numbers dropped dramatically in 2010 and returned by 2011. Conclusions According to our study, patients with scoliosis demonstrated a 0.6575 average incidence increase of PLSF treatments annually. There were significant differences in incidence of PLSF procedure and patient demographics. Additionally, rhBMP-2 consumption significantly changed when we stratified it by sex, age, and region respectively.

Abstract
We present seven epochs of spectropolarimetry of the Type IIb supernova (SN IIb) 2011dh in M51, spanning 86 d of its evolution. The first epoch was obtained 9 d after the explosion, when the photosphere was still in the depleted hydrogen layer of the stripped-envelope progenitor. Continuum polarization is securely detected at the level of P ≈ 0.5 per cent through day 14 and appears to diminish by day 30, which is different from the prevailing trends suggested by studies of other core-collapse SNe. Time-variable modulations in P and position angle are detected across P-Cygni line features. H α and He i polarization peak after 30 d and exhibit position angles roughly aligned with the earlier continuum, while O i and Ca ii appear to be geometrically distinct. We discuss several possibilities to explain the evolution of the continuum and line polarization, including the potential effects of a tidally deformed progenitor star, aspherical radioactive heating by fast-rising plumes of 56Ni from the core, oblique shock breakout, or scattering by circumstellar material. While these possibilities are plausible and guided by theoretical expectations, they are not unique solutions to the data. The construction of more detailed hydrodynamic and radiative-transfer models that incorporate complex aspherical geometries will be required to further elucidate the nature of the polarized radiation from SN 2011dh and other SNe IIb.

ABSTRACTFor the past 15 years, the UCSC Genome Browser (http://genome.ucsc.edu/) has served the international research community by offering an integrated platform for viewing and analyzing information from a large database of genome assemblies and their associated annotations. The UCSC Genome Browser has been under continuous development since its inception with new data sets and software features added frequently. Some release highlights of this year include new and updated genome browsers for various assemblies, including bonobo and zebrafish; new gene annotation sets; improvements to track and assembly hub support; and a new interactive tool, the “Data Integrator”, for intersecting data from multiple tracks. We have greatly expanded the data sets available on the most recent human assembly, hg38/GRCh38, to include updated gene prediction sets from GENCODE, more phenotype- and disease-associated variants from ClinVar and ClinGen, more genomic regulatory data, and a new multiple genome alignment.

The cognitive interview as memory enhancing technique among Arab children
Authors: El Asam Aiman , Samara Muthanna 
Published: September 2015

Purpose
– The purpose of this paper is to examine the Cognitive Interview (CI) and its usefulness in improving recall among Arab children. Totally, 64 Arab children (9-12 years old) took part in this study; they viewed a short video scene followed by the CI or a Structured Interview (control).

Design/methodology/approach
– The study measured for recall of correct, incorrect, confabulated details and accuracy level. Using the interview type, delay type (2-4, 7-10 and 14-16 days) and age group (9-10 and 11-12 years) a MANCOVA test showed that the CI group produced significantly more correct, incorrect and confabulated details compared to the control.

Findings
– Delay had a significant effect on recall of correct detail while the older group of children produced significantly more correct details, higher accuracy and fewer incorrect and confabulated details. Although the CI is a potentially transferable method to be used with Arab children, careful consideration should be given to its difficulty along with cultural issues.

Originality/value
– This is the first study to consider CI among Arab sample of children. Most research have looked at western cultures, hence this study was needed to extend knowledge and test if the CI is transferable to a different culture.
Understanding customer perceptions of internet banking: the case of the UK
Authors: Shanmugam Mohana , Wang Yen-Yao , Bugshan Hatem , Hajli Nick 
Published: September 2015

Purpose
– Existing work on internet banking has provided substantial knowledge of the benefits and economic impacts of internet banking from the bank’s perspective. However, internet banking provides advantages for customers as well as the banking industry. The purpose of this paper is to investigate customer perceptions of internet banking in the UK with the goal of providing a comprehensive understanding of British internet banking.

Design/methodology/approach
– In order to provide the detailed understanding of customers’ perceptions of internet banking, a qualitative study was conducted. The primary method of data collection were 25 interviews. To provide triangulation and increase reliability, various documents and secondary data analyses about internet banking in the UK were also used to supplement the analysis.

Findings
– The results indicate that money transfers and bill payment are the most popular facilities with UK internet banking adopters. More importantly, security is the most important factor affecting the rate of internet banking adoption in the UK. To resolve customers’ security concerns about internet banking, some banks have introduced technologies such as card readers to avoid online fraud. In addition, the authors also found that customers are highly satisfied with internet banking.

Research limitations/implications
– The qualitative nature of the study meant that in-depth interviews with a relatively small sample were the most appropriate method to address the research question. Future studies with larger, more representative sample sizes are encouraged to investigate how the findings can be generalized to larger populations. In addition, due to the popularity of social media, future studies are also advised to examine how they can influence customers’ perceptions of internet banking and boost its adoption rate.

Originality/value
– This paper investigates current perceptions of internet banking in the UK from the customers’ perspective. Therefore, the findings of this study complement with existing work that focusses more on the bank’s perspective to present a comprehensive understanding of this topic.
Häagen-Dazs in Japan: leading brand renewal
Authors: Grossberg Kenneth Alan 
Published: September 2015

Purpose
– After years of financial success with consumers in Japan, the Häagen-Dazs brand suffered accelerating sales declines. This case study presents the three significant reasons and the solutions developed to successfully reinvent the brand.

Design/methodology/approach
– The key to this challenge was the vision and strength of the leader who was tasked with the turnaround and the case looks at his problem assessment, insights and solutions.

Findings
– Even a strong and popular brand needs good leadership to retain its position in the marketplace.

Practical implications
– As your market evolves you need to reinvent your brand constantly, but that does not mean churning the product. In Japan, product churn is an occupational hazard of consumer marketing and, as in this case, resisting such a tendency was the best strategy.

Originality/value
– This case shows that it takes leadership qualities to get innovative strategic initiatives past the marketing gatekeepers who are best at monitoring the status quo but not quick to sense the need for change.
Assessments of neutrophil to lymphocyte ratio and platelet to lymphocyte ratio in Korean patients with psoriasis vulgaris and psoriatic arthritis

Published: September 2015

AbstractThe objective of this retrospective study is to assess neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) as inflammatory markers in patients with psoriasis and psoriatic arthritis (PsA). A hundred and eleven psoriasis patients and 25 PsA patients were compared with 94 healthy controls. Demographic, clinical and laboratory information were collected and analyzed. NLR and PLR were calculated. White blood cell (WBC), neutrophils, eosinophils and NLR were increased in psoriasis patients compared with controls. WBC, neutrophils, NLR, monocytes, platelets and PLR were increased in PsA patients compared with both controls and psoriasis patients. Erythrocyte sedimentation rate (ESR) and C‐reactive protein were significantly higher in PsA patients compared with psoriasis patients. Among psoriasis patients, Psoriasis Area and Severity Index (PASI) score correlated positively with platelets, NLR and PLR. These parameters were all significantly higher in moderate to severe psoriasis patients (PASI ≥ 10) compared with mild patients (PASI < 10). Elevated platelets, NLR and PLR were significantly associated with the increased PASI scores in multivariate analysis. NLR, PLR and ESR were statistically significant predictors for the presence of PsA in psoriasis patients. NLR was the strongest predictor (odds ratio = 3.351, P = 0.005). In conclusion, elevated NLR and PLR were significantly associated with psoriasis and PsA. Both NLR and PLR were strong predictors for the presence of PsA among psoriasis patients.
Public Space and the Public Sphere: The Legacy of Neil Smith
Authors: Low Setha 
Published: September 2015

AbstractThis article attempts to untangle two threads of the intellectual and political legacy of Neil Smith. The first concerns the work that Neil and I did together on theThe Politics of Public Space(Low and Smith, Routledge) on public space and the public sphere and then explains how our paths diverged. I elaborate some of the ways that the public space and public sphere have been expanded by later researchers and that left me with a sense of optimism about the future of public space as a forum for new social and political encounters. The second part of the discussion turns to Neil's thinking and writing as he moved away from having any faith in liberal urban policy, and his conclusion that neoliberalism was waning. Drawing upon publications by his students, I have attempted to assess the impact of his work—particularly on anthropology students focusing on his contribution to gentrification as a global urban strategy and his later turn to revolution as the necessary corrective to the death of neoliberalism. I contrast his revolutionary imperative with my desire to imagine new kinds of translocal public spaces that could expand into a global public sphere.

AbstractHeteroptera are among the most diverse hemimetabolous insects. Seven infraorders have been recognized within this suborder of Hemiptera. Apart from the well‐established sister‐group relationship between Cimicomorpha and Pentatomomorpha (= Terheteroptera), the two terminal lineages, the relationships among the other five infraorders are still controversial, of which three (Gerromorpha, Nepomorpha and Leptopodomorpha) are intimately connected to aquatic environments. However, the various and often conflicting available phylogeny hypotheses do not offer a clear background for a connection between diversification and palaeoenvironments. In this study, a molecular data set representing 79 taxa and 10 149 homologous sites is used to infer the phylogenetic relationships within Heteroptera. Bayesian inference, maximum‐likelihood and maximum parsimony analyses were employed. The results of phylogenetic inferences largely confirm the widely accepted phylogenetic context. Estimation of the divergence time based on the phylogenetic results revealed that Gerromorpha, Nepomorpha and Leptopodomorpha originated successively during the period from the Late Permian to Early Triassic (269–246 Ma). This timescale is consistent with the origin and radiation time of various aquatic holometabolans. Our results indicate that the aquatic and semi‐aquatic true bugs evolved under environmental conditions of high air temperature and humidity in an evolutionary scenario similar to that of the aquatic holometabolans.
Tandem vaginoscopy with colonoscopy: a diagnostic technique for the assessment of colovaginal fistula
Authors: Alkhatib A. A. , Santoro G. A. , Gorgun E. , Abbas M. A. 
Published: September 2015

AbstractAimColovaginal fistula (CVF) has a negative impact on quality of life. Identifying the fistula track is a critical step in its management. In a subset of patients, localizing the fistula preoperatively can be difficult. The purpose of this report is to describe the technique and results of tandem vaginoscopy with colonoscopy (TVC).MethodA retrospective analysis was conducted of all patients referred to a tertiary centre with symptoms suggestive of CVF but no prior successful localization of a fistula. TVC was performed by one colorectal surgeon in the endoscopy suite under intravenous sedation.ResultsBetween 2003 and 2013, 18 patients (median age 58 years) underwent TVC. CVF was ruled out in three patients. In the remaining 15 patients, TVC documented the fistula in 13. In eight cases a wire was passed through the fistulous track from the vagina to the colon, in three the track was large enough to be traversed with the endoscope and in two a fistulous opening was noted on the vaginal side but passage of a wire to localize the opening on the colonic side was not possible due to extensive scarring. No TVC‐related complications were recorded. The sensitivity, specificity, positive predictive value and negative predictive value for TVC in detecting CVF were 86.7%, 100%, 100% and 60%, respectively.ConclusionTVC is a useful technique that can localize the fistulous track in most patients with CVF.
