The Great War at Sea
Authors: Sondhaus Lawrence
Published: August 2014

This is a major new naval history of the First World War which reveals the decisive contribution of the war at sea to Allied victory. In a truly global account, Lawrence Sondhaus traces the course of the campaigns in the North Sea, Atlantic, Adriatic, Baltic and Mediterranean and examines the role of critical innovations in the design and performance of ships, wireless communication and firepower. He charts how Allied supremacy led the Central Powers to attempt to revolutionize naval warfare by pursuing unrestricted submarine warfare, ultimately prompting the United States to enter the war. Victory against the submarine challenge, following their earlier success in sweeping the seas of German cruisers and other surface raiders, left the Allies free to use the world's sea lanes to transport supplies and troops to Europe from overseas territories, and eventually from the United States, which proved a decisive factor in their ultimate victory.
The Life of J. M. W. Turner
Authors: Thornbury Walter
Published: August 2014

This pioneering two-volume biography, first published in 1862, explores the genius of the groundbreaking Romantic landscape and historical painter J. M. W. Turner (1775–1851). As both journalist and historian, author Walter Thornbury (1828–76) has a light touch, yet he draws on a wide range of correspondence, sketchbooks, watercolours and etchings to give a detailed picture of Turner's artistic development and connections, and his increasingly eccentric character. Volume 1 traces the artist's progress from humble cockney beginnings, through youthful friendship and rivalry with Thomas Girtin and a stint as a drawing-master, to his establishment as a Royal Academician at the heart of the nineteenth-century art world. Thornbury sees Turner from all angles, covering his travels at home and abroad, his watercolour and printmaking techniques, his love of sea and sky and colour gradations, and even his fraught monetary dealings. The author also fully contextualises great works like Ulysses Deriding Polythemus and The Fighting Temeraire.
Memoirs of the Life of John Constable, Esq., R.A.
Authors: Constable John
Published: August 2014

First published in 1843 and reissued here in its expanded second edition of 1845, this biography represents an early and informed portrait of the prolific landscape artist and draughtsman John Constable (1776–1837). An upbringing in the East Anglian countryside and his first sighting of a painting by Claude Lorrain inspired his lifelong dedication to capturing scenes from nature, reflected in early works such as Dedham Vale (1802) and in his mature masterpieces, notably The Hay Wain (1821). Prepared by Charles Robert Leslie (1794–1859), a close friend and fellow member of the Royal Academy, this work is based principally on his collection of Constable's letters and papers, drawing also on friends' accounts of the artist. Illuminating his relationship with Maria Bicknell and the influence of early mentor Sir George Beaumont, the book details the development of Constable's career, revealing the nature of his opinions and anxieties.
Inverse Magnus effect on a rotating sphere: when and why
Authors: Kim Jooha , Choi Haecheon , Park Hyungmin , Yoo Jung Yul
Published: August 2014

In some specific conditions, a flying spinning ball deflects in a direction opposite to that predicted by the Magnus effect, which is known as the inverse Magnus effect. To elucidate when and why this effect occurs, we measure the variations of the drag and lift forces on a rotating sphere and the corresponding flow field with the spin ratio (the ratio of the rotational velocity to the translational one). This counterintuitive phenomenon occurs because the boundary layer flow moving against the surface of a rotating sphere undergoes a transition to turbulence, whereas that moving with the rotating surface remains laminar. The turbulence energizes the flow and thus the main separation occurs farther downstream, inducing faster flow velocity there and generating negative lift force. Empirical formulae are derived to predict the location where the flow separates as a function of the Reynolds number and the spin ratio. Using the formulae derived, the condition for the onset of the inverse Magnus effect is suggested based on the negative lift generation mechanism.

Published: August 2014

Little is known about the mediating effects of the determinants of fruit and vegetable (FV) intake in school-based interventions that promote FV intake, and few studies have examined the impact of the degree of implementation on the effects of an intervention. The present study examined whether the degree of implementation of an intervention had an effect on children's fruit or vegetable intake and determined possible mediators of this effect. The study is part of the European PRO GREENS intervention study which aimed to develop effective strategies to promote consumption of fruit and vegetables in schoolchildren across Europe. Data from 727 Finnish children aged 11 years were used. The baseline study was conducted in spring 2009 and the follow-up study 12 months later. The intervention was conducted during the school year 2009–2010. The effects were examined using multilevel mediation analyses. A high degree of implementation of the intervention had an effect on children's fruit intake. Knowledge of recommendations for FV intake and liking mediated the association between a high degree of implementation of the intervention and an increase in the frequency of fruit intake. Knowledge of recommendations for FV intake and bringing fruits to school as a snack mediated the association between a low degree of implementation of the intervention and an increase in the frequency of fruit intake. Overall, the model accounted for 34 % of the variance in the change in fruit intake frequency. Knowledge of recommendations acted as a mediator between the degree of implementation of the intervention and the change in vegetable intake frequency. In conclusion, the degree of implementation had an effect on fruit intake, and thus in future intervention studies the actual degree of implementation of interventions should be assessed when considering the effects of interventions.

Vitamins B2and B6are cofactors in the kynurenine pathway. Many of the kynurenines are neuroactive compounds with immunomodulatory effects. In the present study, we aimed to investigate plasma concentrations of vitamins B2and B6as determinants of kynurenines and two markers of interferon-γ-mediated immune activation (kynurenine:tryptophan ratio (KTR) and neopterin). We measured the concentrations of vitamins B2and B6vitamers, neopterin, tryptophan and six kynurenines (i.e. kynurenine, anthranilic acid, kynurenic acid, 3-hydroxykynurenine, 3-hydroxyanthranilic acid and xanthurenic acid) in plasma from 7051 individuals. Dietary intake of vitamins B2and B6was assessed using a validated FFQ. Associations were investigated using partial Spearman's correlations, generalised additive models, and segmented or multiple linear regression. The B2vitamer, riboflavin, was positively associated with 3-hydroxyanthranilic acid and xanthurenic acid, with correlation coefficients, as obtained by segmented regression, of 0·20 (95 % CI 0·16, 0·23) and 0·24 (95 % CI 0·19, 0·28), at riboflavin concentrations below the median value (13·0 nmol/l). The vitamin B6vitamer, pyridoxal 5′-phosphate (PLP), was positively associated with most kynurenines at PLP concentrations < 39·3–47·0 nmol/l, and inversely associated with 3-hydroxykynurenine with the association being more prominent at PLP concentrations < 18·9 nmol/l. Riboflavin and PLP were associated with xanthurenic acid only at relatively low, but normal concentrations of both vitamers. Lastly, PLP was negatively correlated with neopterin and KTR. These results demonstrate the significant and complex determination of kynurenine metabolism by vitamin status. Future studies on B-vitamins and kynurenines in relation to chronic diseases should therefore integrate data on relevant biomarkers related to B-vitamins status and tryptophan metabolism.
Anxiety and Vote Decision Making in Winner-Take-All Elections
Authors: Dumitrescu Delia , Blais André
Published: August 2014

We study strategic voting behaviour in winner-take-all elections by means of an original study in which participants vote to collectively decide how much money should be given to an environmental NGO. We find that supporters of the most NGO-friendly party are reluctant to abandon it, despite its poor electoral viability. The poor electoral viability generates significant anxiety among its supporters and the level of anxiety at the time of voting influences their choice. Moderate levels of anxiety increase the probability of defection, but at high levels, anxiety has a paralyzing effect, making voters less likely to abandon their preferred choice.
Charles Marowitz in London: Twenty-Five Years Hard: Marowitz in the Sixties
Authors: Trussler Simon
Published: August 2014

Charles Marowitz, who died on 2 May this year, arrived in England from his native New York in 1956, on a scholarship earned for service in Korea. He immediately found in Unity Theatre a venue for his first London production, and in the following year opened his own theatre – an attic in the headquarters of the British Drama League known as In-Stage. In 1981, after the closure of his last and longest London base, the Open Space Theatre in Tottenham Court Road, he left, disillusioned with his adopted country, to settle in California, creating companies in Los Angeles and in his new home of Malibu. But during the momentous decade of the sixties it was British theatre that Marowitz helped to reshape – not least in developing London's still flourishing ‘fringe’. In this feature, NTQ co-editor Simon Trussler celebrates not only Marowitz's directing career, on which many obituarists have written, but also – through personal recollections of the man in those early years – the many other ‘hats’ he wore: as theatre critic, editor, playwright, and cultural entrepreneur. Marowitz's long-term professional partner, Thelma Holt, shares her own memories of the twelve years when together they formed and ran the Open Space. Marowitz contributed to the old TQ and to New Theatre Quarterly, but here we include some of the articles he wrote in later life for the online Swans Commentary, to which we are most grateful for permission to reprint. All are from 2012, when Parkinson's disease was tightening its hold, and so are among the very last pieces he wrote.
Working with Havel
Authors: Marowitz Charles
Published: August 2014

In the spring of 2004, I was invited to Prague to direct Vaclav Havel's Temptation at the National Theatre in the Czech Republic. I had directed in a number of European cities but there was something of a frisson about going to Prague and working with the ex-president of the Czech Republic, whom I remembered most vividly as the Great Dissenter against Soviet rule in a city I had often visualized but never actually seen.

On the day Vaclav Havel was scheduled to attend the first-act run-through of his play there was a palpable sense of hysteria in the air. The actors, all highly experienced members of a robust and respected permanent company that performed regularly before the upper echelons of Prague society, had never played in a scrappy rehearsal room for an internationally lauded political icon and ex-president of the Czech Republic surrounded by secret service men. Lines were muffed, moves went awry, cues forgotten, and a sense of a ‘Royal Command Performance’ hung in the air. After an hour or so, the torture was over and the actors sat circled around an appreciative, avuncular, and soft-spoken playwright, being gently massaged with compliments and diverted by anecdotes about his numerous incarcerations, the play's inception, and the thrill of being back in the midst of working actors after an absence of some twenty-five years.
Ibsen Our Contemporary
Authors: Hornby Richard
Published: August 2014

In this article Richard Hornby argues that Ibsen's plays are badly performed today, or not performed at all, because of directors' refusal to take them with appropriate seriousness. The tendency is to stage the plays' reputation as simplistic social problem plays rather than as the complex, challenging, bizarre dramas that Ibsen actually wrote. In particular, directors avoid the grotesque elements that are the true ‘quintessence of Ibsenism’, and that are often remarkably similar in style to that of avant-garde playwrights today. Richard Hornby is Emeritus Professor of Theatre at the University of California, Riverside. For the past twenty-eight years he has been theatre critic for The Hudson Review, and is author of six books and over two hundred published articles on various aspects of theatre. This essay was delivered as the keynote address at the fourteenth annual Ibsen Festival of the Commonweal Theatre Company, Lanesboro, Minnesota, in April 2011.
The Roaring Girl in Retrospect: the RSC Production of 1983
Authors: Sophia Li Chi-fang
Published: August 2014

With its second revival of The Roaring Girl now in the Royal Shakespeare Company's repertory, Chi-fang Sophia Li documents in this article the making of the first production, as directed by Barry Kyle in 1983. She reviews the other RSC productions that informed Kyle's directorial approach, and, using the Shakespeare Birthplace Trust Library's archival materials and a research interview, she attempts a reconstructive criticism of Kyle's project of ‘theatrical archaeology’, arguing that what Kyle did was adapt Dekker and Middleton's Jacobean angst about the radical economic changes of the first decade of King James's reign to articulate current anxieties about Thatcherite economic ‘reforms’. The revival became compellingly invested with Kyle's critical reflections on triumphalist capitalism and ‘Victorian values’. Chi-fang Sophia Li is Assistant Professor of the Department of Foreign Languages and Literature at National Sun Yat-sen University in Taiwan. She has also published in Shakespeare Bulletin, Notes and Queries, and English Studies (Routledge), and in Chinese in Review of English and American Literature.

Perceptions of Corruption and the Dynamics of Women's Representation
Authors: Watson David , Moreland Amy
Published: August 2014

A growing body of literature focuses on the attitudes produced by women's representation. One area of particular interest is the effect of women's representation on perceptions of corruption in government. Multiple scholars have found that citizens view women in government as more trustworthy and less corrupt. Others have suggested that the link between gender and corruption is spurious or dependent upon regime characteristics. Additionally, many studies of women's effect on corruption were published prior to the widespread adoption of gender quotas, when levels of women's representation were considerably lower. We argue that the relationship between women and perceptions of corruption can be better understood by applying an integrated model of representation, which explores the effects of formal, descriptive, and substantive representation on perceptions of corruption. Using a time-series analysis of 140 countries worldwide from 1998–2011, this study finds that women's descriptive and substantive representation are correlated with lower perceptions of corruption. However, gender quotas are correlated with higher perceptions of corruption among political elites.
A Tribute to the Women: Rewriting History, Retelling Herstory in Civil Rights
Authors: Simien Evelyn M. , McGuire Danielle L.
Published: August 2014

Much of the scholarship on the modern Civil Rights Movement (CRM) has recaptured dramatic and poignant events through eyewitness accounts and oral narratives—from letters, speeches, newspaper editorials, press releases, photographs, and documentary films that summon vivid images of fire hoses and police dogs, peaceful protestors, and violent rioters (McAdam 1982; Morris 1984; Payne 1994; Robnett 1997; Williams 1988). The conventional approach to (or master narrative of) civil rights history has focused almost exclusively on extraordinary, elite men from W.E.B. DuBois to Martin Luther King Jr. and Thurgood Marshall to such notable civil rights organizations as the National Association for the Advancement of Colored People (NAACP), the Southern Christian Leadership Conference (SCLC), and the Student Nonviolent Coordinating Committee (SNCC)—that led the fight for equal protection under the law, desegregated lunch counters, and the right to vote in local and national elections (Branch 1988, 1998, 2006; Carson 1981; Fairclough 1987; Garrow 1986; Lewis 1993; Reed 1997; Sullivan 2009). Rather than broaden and deepen our understanding of individual and collective forms of resistance, however, such an approach simplifies and distorts a more nuanced and complicated version of civil rights history in the United States. All too often people come to associate the modern CRM with celebrated heroes and a static, fixed understanding of discrimination that is less than critical of hierarchal relationships determined solely (or primarily) by a racial caste system—specifically, an era of Jim Crow when “separate but equal” accommodations were legally sanctioned by the Supreme Court's Plessy v. Ferguson decision. Far less common is an association of the modern CRM with a richer, more nuanced understanding of discrimination that is critical of hierarchal relationships determined by interlocking systems of oppression—namely, racism and sexism—experienced by forgotten heroines who similarly risked their lives and reputations for equality and justice before the law (notable exceptions being Collier-Thomas and Franklin 2001; Giddings 1984; Gilmore 1996; Ling and Monteith 2004; Olson 2001; Robnett 1997).
Introduction
Authors: Mershon Carol , Walsh Denise
Published: August 2014

Scholars of marginalized groups are experts on attitudes, behaviors, practices, and institutions that resist inclusion and reproduce bias. Many scholars who study marginalization also work from first-hand experience of it. Although academic experiences of marginalization usually occur in sites of middle-class privilege, the effects can be profound. Women in the U.S. political science profession continue to be underrepresented, and women of color severely so. This sends the message to all students that women lack the capacity to be scientists. Women in academe often internalize that message and too rarely seek leadership positions. When they do, their achievements are characterized as tokenism and devalued, revealing a hostile gender climate that enables bias to flourish. That bias is reflected in salary discrepancies, resource distribution, and service responsibilities (e.g., APSA 2011; Monroe et al. 2008).
Developing Experience, Networks, and Capacities: Leadership as Practiced in Feminist Human Rights Activism
Authors: Ackerly Brooke A.
Published: August 2014

This essay draws on insights from research into human rights activism to propose a feminist human rights account of leadership that could be applied to political science. I advance the view that the practice of leadership is one of building networks and strengthening the capacity of others to advocate for themselves and their communities. In this view, leadership leverages the political and strategic capacities made possible by relative positions of privilege and so transforms the networks, capacities, and privileges of others. Mentoring is an integral part of this activist approach to leadership. In this view, leadership and mentoring are about developing the networks that make transformation possible; they are collective and political. For illustration, I begin with insights about the importance of networks learned through a personal experience in Bangladesh and juxtapose that experience with the experience of Bangladeshi labor rights organizers before providing a more general account of two key aspects of this leadership: building networks and strengthening capacity in others.
Transforming a Department, Transforming a Discipline
Authors: Daniels Cynthia R.
Published: August 2014

The Department of Political Science at Rutgers has a deep and sustained commitment to the principle of diversity. A diverse scholarly community is crucial to the development of cutting edge social science research, the recruitment and training of diverse graduate students, the quality of pedagogical experiences in our undergraduate classrooms and to the vibrancy and life of the University. (unanimously affirmed, May 2011)

In the fall of 2009, I became the first woman chair of the political science department at Rutgers University. I entered the position on the heels of a major gender discrimination case involving all of the women in the department, who claimed salary inequities and also put forward a series of informal complaints about hostile work environment. The case had taken two years to settle and, at its conclusion, the dean of the School of Arts and Sciences suggested that the department consider electing one of the women as chair. Needless to say, the challenges before the department were quite daunting.
Hypermetabolic State in the 7-Month-Old Triple Transgenic Mouse Model of Alzheimer'S Disease and the Effect of Lipoic Acid: A 13C-NMR Study
Authors: Sancheti Harsh , Patil Ishan , Kanamori Keiko , Brinton Roberta Díaz , Zhang Wei , Lin Ai-Ling , Cadenas Enrique
Published: August 2014

Alzheimer's disease (AD) is characterized by age-dependent biochemical, metabolic, and physiologic changes. These age-dependent changes ultimately converge to impair cognitive functions. This study was carried out to examine the metabolic changes by probing glucose and tricarboxylic acid cycle metabolism in a 7-month-old triple transgenic mouse model of AD (3×Tg-AD). The effect of lipoic acid, an insulin-mimetic agent, was also investigated to examine its ability in modulating age-dependent metabolic changes. Seven-month-old 3×Tg-AD mice were given intravenous infusion of [1-13C]glucose followed by an ex vivo13C nuclear magnetic resonance to determine the concentrations of 13C-labeled isotopomers of glutamate, glutamine, aspartate, gamma aminobutyric acid, and N-acetylaspartate. An intravenous infusion of [1-13C]glucose+[1,2-13C]acetate was given for different periods of time to distinguish neuronal and astrocytic metabolism. Enrichments of glutamate, glutamine, and aspartate were calculated after quantifying the total (12C+13C) concentrations by high-performance liquid chromatography. A hypermetabolic state was clearly evident in 7-month-old 3×Tg-AD mice in contrast to the hypometabolic state reported earlier in 13-month-old mice. Hypermetabolism was evidenced by prominent increase of 13C labeling and enrichment in the 3×Tg-AD mice. Lipoic acid feeding to the hypermetabolic 3×Tg-AD mice brought the metabolic parameters to the levels of nonTg mice.
Alarmin S100A8/S100A9 as a biomarker for molecular imaging of local inflammatory activity

Published: August 2014

Inflammation has a key role in the pathogenesis of various human diseases. The early detection, localization and monitoring of inflammation are crucial for tailoring individual therapies. However, reliable biomarkers to detect local inflammatory activities and to predict disease outcome are still missing. Alarmins, which are locally released during cellular stress, are early amplifiers of inflammation. Here, using optical molecular imaging, we demonstrate that the alarmin S100A8/S100A9 serves as a sensitive local and systemic marker for the detection of even sub-clinical disease activity in inflammatory and immunological processes like irritative and allergic contact dermatitis. In a model of collagen-induced arthritis, we use S100A8/S100A9 imaging to predict the development of disease activity. Furthermore, S100A8/S100A9 can act as a very early and sensitive biomarker in experimental leishmaniasis for phagocyte activation linked to an effective Th1-response. In conclusion, the alarmin S100A8/S100A9 is a valuable and sensitive molecular target for novel imaging approaches to monitor clinically relevant inflammatory disorders on a molecular level.

Published: August 2014

IP3-3K [Ins(1,4,5)P3 3-kinase] is a key enzyme that catalyses the synthesis of Ins(1,3,4,5)P4, using Ins(1,4,5)P3 and ATP as substrates. Both inositides, substrate and product, present crucial roles in the cell. Ins(1,4,5)P3 is a key point in Ca2+ metabolism that promotes Ca2+ release from intracellular stores and together with Ins(1,3,4,5)P4 regulates Ca2+ homoeostasis. In addition, Ins(1,3,4,5)P4 is involved in immune cell development. It has been proved that Ca2+/CaM (calmodulin) regulates the activity of IP3-3K, via direct interaction between both enzymes. Although we have extensive structural knowledge of the kinase domains of the three IP3-3K isoforms, no structural information is available about the interaction between IP3-3K and Ca2+/CaM. In the present paper we describe the crystal structure of the complex between human Ca2+/CaM and the CaM-binding region of human IP3-3K isoform A (residues 158–183) and propose a model for a complex including the kinase domain. The structure obtained allowed us to identify all of the key residues involved in the interaction, which have been evaluated by site-directed mutagenesis, pull-down and fluorescence anisotropy experiments. The results allowed the identification of a new CaM-binding motif, expanding our knowledge about how CaM interacts with its partners.

Purpose

Hyperacusis can be extremely debilitating, and at present, there is no cure. In this detailed review of the field, we consolidate present knowledge in the hope of facilitating future research.

Method

We review and reference the literature on hyperacusis and related areas. This is the 2nd of a 2-part review.

Results

Hyperacusis encompasses a wide range of reactions to sounds, which can be grouped into the categories of excessive loudness, annoyance, fear, and pain. Reasonable approaches to assessing the different forms of hyperacusis are emerging, including brain-imaging studies. Researchers are only beginning to understand the many mechanisms at play, and valid animal models are still evolving. There are many counseling and sound-therapy approaches that some patients find helpful, but well-controlled studies are needed to measure their long-term efficacy and to test new approaches.

Conclusions

Hyperacusis can make life difficult in this increasingly noisy world, forcing sufferers to dramatically alter their work and social habits. We believe this is an opportune time to explore approaches to better understand and treat hyperacusis.
Relationships Between Narrative Language Samples and Norm-Referenced Test Scores in Language Assessments of School-Age Children
Authors: Ebert Kerry Danahy , Scott Cheryl M.
Published: August 2014

Purpose

Both narrative language samples and norm-referenced language tests can be important components of language assessment for school-age children. The present study explored the relationship between these 2 tools within a group of children referred for language assessment.

Method

The study is a retrospective analysis of clinical records from 73 school-age children. Participants had completed an oral narrative language sample and at least one norm-referenced language test. Correlations between microstructural language sample measures and norm-referenced test scores were compared for younger (6- to 8-year-old) and older (9- to 12-year-old) children. Contingency tables were constructed to compare the 2 types of tools, at 2 different cutpoints, in terms of which children were identified as having a language disorder.

Results

Correlations between narrative language sample measures and norm-referenced tests were stronger for the younger group than the older group. Within the younger group, the level of language assessed by each measure contributed to associations among measures. Contingency analyses revealed moderate overlap in the children identified by each tool, with agreement affected by the cutpoint used.

Conclusions

Narrative language samples may complement norm-referenced tests well, but age combined with narrative task can be expected to influence the nature of the relationship.
Numerical analysis of queuing delay in cyclic bandwidth allocation TDMA system
Authors: Choi Hyun‐Kyun , Choi Jeong‐Dan , Jang Youn‐Seon
Published: August 2014

A model of the queue operation in a cyclic bandwidth allocation time division multiple access (TDMA) system is proposed and formulas to estimate the queuing delay from the model are derived. In the queue modelling, a cyclic bandwidth allocation algorithm is used, which allocates the bandwidth periodically for multiple access control. From the simplified numerical analysis, one can estimate intuitively the queuing delay in the cyclic bandwidth allocation TDMA system. It will be very useful in system design and implementation.
K‐band CMOS frequency doubler with high fundamental rejection
Authors: Wang Sen , Chang Chun‐Tuan
Published: August 2014

The design of a frequency doubler with current‐reuse and fundamental rejection topology is presented. The frequency doubler is fabricated by a standard 0.18 μm CMOS process with a chip size of 0.57 mm2. The DC power consumption is 13.9 mW. In addition, the measured conversion gain is between –4.4 and –5.24 dB from 10 to 12 GHz input frequency. With the proposed active notch filter in the cascode stage of the doubler, a superior fundamental rejection is obtained. The measured fundamental rejection is between 32.4 and 53.8 dB.
Single‐carrier frequency domain equalisation proposal for very long haul HF radio links
Authors: Hervás M. , Pijoan J.L. , Alsina‐Pagès R.M. , Salvador M. , Badia D.
Published: August 2014

A single carrier frequency domain equalisation (SC‐FDE) modulation scheme which represents a step forward in the investigation since it obtains higher bit rates than previous proposals with spread spectrum techniques is presented. The focus of this reported work is the data transmission from remote sensors using very low‐power HF ionospheric communications. In particular, the authors' research group has been studying the ionospheric channel parameters and data transmission techniques from Antarctica since 2003. Both, the spread spectrum and multicarrier modulations have been tested previously in order to obtain a good trade‐off between bit error rate and bit rate. A proof of principle of the single carrier technique with promising results is presented.
Ultra‐wideband bandpass filter using multi‐stub‐loaded ring resonator
Authors: Lin Lei , Yang Shuai , Sun Shou‐Jia , Wu Bian , Liang Chang‐Hong
Published: August 2014

A compact ultra‐wideband (UWB) bandpass filter (BPF) using a multi‐stub‐loaded ring resonator is presented. The resonant frequencies of the proposed resonator can be tuned freely by changing the lengths of the corresponding stubs. By utilising the proposed multimode resonator, four resonant frequencies are evenly allocated in the UWB range and two transmission zeros are introduced at the lower and upper stopbands. Parallel‐coupled feedlines with defected ground structures were utilised to provide sufficient external coupling. To validate the design theory, an UWB BPF operating in the frequency range from 3.1 to 10.6 GHz was designed, analysed and fabricated. Measurements showed good agreement with simulations.

Published: August 2014

Substrate integrated waveguide (SIW) matching terminations or loads are proposed for low‐cost integration in SIW circuits and systems. The principles of narrowband and broadband SIW terminations are demonstrated and discussed. Both narrowband and broadband terminations are optimised, fabricated and measured over the frequency range of 6–15 GHz. Relative frequency bandwidths (|S11| < 20 dB) of the narrowband and broadband terminations are 7.6 and 42.6%, respectively. Good agreement between the measured and simulated results validates the feasibility of the proposed design strategies of SIW terminations.
Subgradient projection for sparse signal recovery with sparse noise
Authors: Sun Tao , Zhang Hui , Cheng Lizhi
Published: August 2014

Recovering sparse signals from a few linear measurements with sparse noise is attracting growing attention. Such a problem has appeared in a diverse set of fields such as super‐resolution, image inpainting and face recognition. A new model for this problem on learning the sparsity of the signal is presented. A corresponding algorithm is also presented by combining the subgradient method and the hard thresholding pursuit strategy. Numerical results demonstrate the efficiency of the model and algorithm.

Published: August 2014

An impedance compensated passive implantable atrial defibrillator is reported. The two‐part system consists of a handheld lithium‐ion powered base unit (external power transmitter) and a passive (battery free) implantable coil (power receiver), with integrated rectifilter and power control unit, electrocardiogram (ECG) and bioimpedance measurement circuits, data communications circuitry and atrial connection leads. The system is designed to operate in two distinct modes: cardiac sense mode (wake‐up, measure the impedance of the cardiac substrate and communicate data to the external base unit) and shock mode (delivery of an ECG synchronised impedance compensated monophasic very low tilt rectilinear shock waveform). A prototype was implemented and tested. In the sense mode, up to 5 W of sustained DC power was delivered across a 2.5 cm air–skin barrier with approximately 40% DC‐to‐DC power transfer efficiency at a transmission frequency of 185 kHz achieved, thereby providing 15.9 VDC (320 mA) to the implant side for measurement and communication at 433 MHz with the base unit. In the shock delivery mode, >186.9 W (rectilinear monophasic shock pulse: 100 V, 1.9 A, 12 ms duration) was repeatedly and reliably delivered transcutaneously to a 50 Ω cardiac load. Further testing in ten porcine models verified the in vivo operation, with inter‐catheter impedance variations of ±20.1% measured between successive defibrillation attempts.
