Characteristics and prognostic factors for head and neck non-Hodgkin's lymphoma in Chinese patients
Authors: Wang J , Cai C-P , He S-F , Wang S-L 
Published: June 2013

AbstractBackground and objectives:The head and neck region is the second most frequent anatomical site of extranodal lymphomas. These tumours affect many individuals worldwide, justifying epidemiological studies in different countries. This study evaluated the characteristics, treatments and prognostic factors for non-Hodgkin's lymphoma of the head and neck in Chinese patients.Method:The clinical manifestations, clinicopathological characteristics, multidisciplinary treatment and prognostic factors for 102 patients with extranodal non-Hodgkin's lymphoma of the head and neck were analysed retrospectively.Result:The tonsil was the most commonly involved primary site, followed by the nasal cavity. The most common histological subtype was diffuse large B-cell lymphoma, followed by natural killer T-cell lymphoma. Patients receiving a combination of rituximab and chemotherapy did better than those receiving chemotherapy alone. Prognosis was significantly associated with both International Prognostic Index and histological subtype; the former was especially strongly associated with poor survival.Conclusion:In this group of Chinese patients, diffuse large B-cell lymphoma was the most common pathological subtype, but the incidence of T-cell lymphomas was higher than that reported in the USA. Combined rituximab and chemotherapy led to better outcomes than chemotherapy alone. Prognosis depended on both International Prognostic Index and histological subtype.
Hyperbaric oxygen therapy for sudden sensorineural hearing loss in large vestibular aqueduct syndrome
Authors: Shilton H , Hodgson M , Burgess G 
Published: June 2013

AbstractIntroduction:We report the first use in Australia of hyperbaric oxygen therapy for sudden hearing loss following head trauma in a child with large vestibular aqueduct syndrome.Case report:A 12-year-old boy with large vestibular aqueduct syndrome presented with significant hearing loss following head trauma. He was treated with steroids and hyperbaric oxygen therapy, with good improvement of hearing thresholds on audiography. This case represents the first reported use of hyperbaric oxygen therapy for this indication in Australia, following a few previous reports of patients in Japan. We review the literature on management of acute sensorineural hearing loss in large vestibular aqueduct syndrome. The reported case demonstrates a potentially beneficial therapy for a rare condition that usually results in an inevitable decline in hearing.Conclusion:Hyperbaric oxygen therapy can be tolerated well by children, and may represent a potential treatment for sudden sensorineural hearing loss in patients with large vestibular aqueduct syndrome.

Published: June 2013

BackgroundCardiovascular fitness influences many aspects of brain function. However, the relationship between cardiovascular fitness and suicidal behaviour is unknown. Therefore, we aimed to determine whether cardiovascular fitness at age 18 years is associated with future risk of suicide attempt/death.MethodWe performed a population-based Swedish longitudinal cohort study of male conscripts with no previous or ongoing mental illness (n = 1 136 527). The conscription examination, which took place during 1968–2005, included the cycle ergonometric test and tests of cognitive performance. Future risk of suicide attempt/death over a 5- to 42-year follow-up period was calculated with Cox proportional hazards models controlling for several confounders including familial factors.ResultsAt least one suicide attempt was recorded for 12 563 men. Death by suicide without a prior attempt was recorded in 4814 additional individuals. In fully adjusted models low cardiovascular fitness was associated with increased risk for future attempt/death by suicide [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.64–1.94]. The HR changed only marginally after exclusion of persons who received in-patient care for depression (HR 1.76, 95% CI 1.61–1.94). Poor performance on both the cardiovascular fitness and cognitive tests was associated with a fivefold increased risk of suicide attempt or suicide death (HR 5.46, 95% CI 4.78–6.24).ConclusionsLower cardiovascular fitness at age 18 years was, after adjustment for a number of potential confounders, associated with an increased risk of attempt/death by suicide in adulthood. It remains to be clarified whether interventions designed to improve fitness in teens can influence the risk of suicidal behaviour later in life.
To be or not to be? Public archaeology as a tool of public opinion and the dilemma of intellectuality
Authors: Sánchez Jaime Almansa 
Published: June 2013

AbstractStating the value of archaeology for contemporary society is a very difficult task hardly undertaken by archaeologists. Work with a contemporary record directly linked to local communities, and the approach of public archaeology, have helped to bring society and archaeology closer together. However, the role of a public intellectual goes beyond archaeology, delving into current social worries. Is it possible to play this game from archaeology? The multiple and complex relations between archaeology and society open the door to participation in public debates, but we stand to lose our essence. We face a Shakespearean dilemma, a choice between having an influential voice in the present, or just an expert opinion.
The need and potential for an archaeology orientated towards the present
Authors: Holtorf Cornelius 
Published: June 2013

AbstractThe question ‘Can an archaeologist be a public intellectual?’ appears to express both an unfulfilled desire and a secret hope of an entire professional corps to count among them at least a few public intellectuals. I suggest that the state of the discipline of archaeology makes it harder, compared with other disciplines, for its professional representatives to address present-day issues and relate to public debates. I also suggest that maybe the most significant effect of the fact that society's public intellectuals generally do not have degrees in archaeology is that participants in public debates and policy makers are unaware of how various applications of archaeology and cultural heritage can benefit contemporary society. This potential will therefore have to be realized in different ways.
Exerting influence? Responsibility and the public role of archaeology in divided societies
Authors: Horning Audrey 
Published: June 2013

AbstractCan, or should, archaeologists adopt the mantle of the public intellectual and bring archaeology to bear on contemporary issues within divided societies? The line between the archaeologist and the citizen is never clear-cut. How do we balance the recognition that our knowledge and expertise allow us to exert influence with the necessity to act as responsible members of our own societies? I define a public intellectual as one who is not afraid to step outside professional circles and comfort zones and to engage, challenge and comment on issues of broad relevance in the present. Employing Northern Ireland as a case study, I argue that archaeologists have a responsibility to provide leadership and commentary regarding the fraught relationship between past and present.
The dead and their public. Memory campaigns, issue networks and the role of the archaeologist in the excavation of mass graves
Authors: Renshaw Layla 
Published: June 2013

AbstractThis contribution will consider how the practice of archaeology ‘brings a public into being’. Drawing on examples of the excavation of mass graves from the Spanish Civil War and the First World War, particularly those cases resulting from activism on the part of memory campaign groups, this paper considers how the act of excavation can serve as a catalyst for members of the public to coalesce and deliberate the complex and far-reaching questions associated with the post-mortem treatment and commemoration of the dead. The necessity to fulfil the aims of particular constituencies, such as the relatives of the dead, or the need to maintain a position of impartiality, may militate against the archaeologist's full intellectual engagement with these questions, resulting in the archaeologist's role being defined primarily by their technical or practical contribution. The concept of the issue network is explored as a way to understand the formation of memory campaigns and the archaeologist's relationship with the public. The idea of the network underlines the potential for the archaeologist to make an intellectual contribution that develops and democratizes the debate surrounding an excavation, even if their position is contested, and so bring a wider public into being.
Entering history? Archaeologists as intellectualsà la recherche du temps perdu
Authors: Schlanger Nathan 
Published: June 2013

AbstractFollowing some comments on the notion of ‘public’ intellectuals (can they be otherwise?), this brief paper focuses on the intellectual roles that could be played by archaeologists today. Exposure to the media, usually following some spectacular discovery, serves to confirm the romantico-empirical image of the discipline, but should also lead to an engagement with key public debates. Three such debates are indicated: the idea that ‘African man has yet to enter history’ as expressed by the former French president; the creation of a Maison de l'histoire de France under the tutelage of the Ministry of National Identity; and, across the Channel, the Localism Bill, which pushes decision making to an untenably low level while promoting a historically and archaeologically questionable view of local communities.
Towards a post-colonial artefact analysis
Authors: Van Oyen Astrid 
Published: June 2013

AbstractThis paper argues that material culture should be brought even more to the forefront in post-colonial archaeology. At present, post-colonial analyses start from a baseline of pinned-down, delineated things as processed through artefact analysis, to proceed to interpretations of how these things were used in fluid, multidirectional, ambivalent social and cultural interactions. But what if thingsthemselvescan be fluid rather than bounded? Can we look into the various ways in which things were defined in the past, and the various relations they enabled? Such a change of perspective can also help redress the imbalance within post-colonial studies between, on the one hand, consumption as the field in which meaning is negotiated and, on the other hand, production as offering merely a template for the inscription of that meaning. A case study of so-called pre-sigillata production in southern Gaul articulates the benefit to be gained from considering these issues.
The sportification of judo: global convergence and evolution
Authors: Sato Shohei 
Published: June 2013

AbstractThis article re-examines our understanding of modern sport. Today, various physical cultures across the world are practised under the name of sport. Almost all of these sports originated in the West and expanded to the rest of the world. However, the history of judo confounds the diffusionist model. Towards the end of the nineteenth century, a Japanese educationalist amalgamated different martial arts and established judo not as a sport but as ‘a way of life’. Today it is practised globally as an Olympic sport. Focusing on the changes in its rules during this period, this article demonstrates that the globalization of judo was accompanied by a constant evolution of its character. The overall ‘sportification’ of judo took place not as a diffusion but as a convergence – a point that is pertinent to the understanding of the global sportification of physical cultures, and also the standardization of cultures in modern times.
Playing to the ‘imaginary grandstand’: sport, the ‘British world’, and an Australian colonial identity
Authors: van Duinen Jared 
Published: June 2013

AbstractThis article argues for the importance of an exploration of sporting interactions in the British world. In addition, it presents the case for the adaptation of borderlands theory to the British world framework. Such study of British world borderlands is capable of more accurately capturing the spatial and regional variety of this British world and, in particular, the nascent national identities of dominions such as Australia. Sport is a particularly apt vehicle for the examination of such issues in an Australian context, since playing to the ‘imaginary grandstand’ of international spectators has always occupied a central role in the construction of an Australian national identity. This article uses three brief case studies – cricket, swimming, and Australian Rules football – to explore these theoretical claims.
Quantifying community assembly processes and identifying features that impose them

Published: June 2013

Abstract
Spatial turnover in the composition of biological communities is governed by (ecological) Drift, Selection and Dispersal. Commonly applied statistical tools cannot quantitatively estimate these processes, nor identify abiotic features that impose these processes. For interrogation of subsurface microbial communities distributed across two geologically distinct formations of the unconfined aquifer underlying the Hanford Site in southeastern Washington State, we developed an analytical framework that advances ecological understanding in two primary ways. First, we quantitatively estimate influences of Drift, Selection and Dispersal. Second, ecological patterns are used to characterize measured and unmeasured abiotic variables that impose Selection or that result in low levels of Dispersal. We find that (i) Drift alone consistently governs ∼25% of spatial turnover in community composition; (ii) in deeper, finer-grained sediments, Selection is strong (governing ∼60% of turnover), being imposed by an unmeasured but spatially structured environmental variable; (iii) in shallower, coarser-grained sediments, Selection is weaker (governing ∼30% of turnover), being imposed by vertically and horizontally structured hydrological factors;(iv) low levels of Dispersal can govern nearly 30% of turnover and be caused primarily by spatial isolation resulting from limited exchange between finer and coarser-grain sediments; and (v) highly permeable sediments are associated with high levels of Dispersal that homogenize community composition and govern over 20% of turnover. We further show that our framework provides inferences that cannot be achieved using preexisting approaches, and suggest that their broad application will facilitate a unified understanding of microbial communities.
Planar ultra‐wideband antenna with five notched stop bands
Authors: Liu J.J. , Esselle K.P. , Hay S.G. , Zhong S.S. 
Published: June 2013

A printed ultra‐wideband (UWB) antenna with five notched stop bands is presented. By introducing a pair of arc‐shaped slots, two defected ground structures and an open‐loop resonator, five sharp notches are achieved at frequencies of 2.4, 3.2, 5.2, 5.8 and 7.5 GHz. The proposed antenna has been fabricated and tested. The measured results indicate that the proposed design not only supports UWB bandwidth requirements but rejects five narrow bands to avoid possible interference with existing communication systems. In addition, the proposed antenna has relatively omnidirectional radiation patterns in passbands.

Published: June 2013

Antennas proximity produces the antennas correlation effect which impacts MIMO systems performance. This reported work analyses the singular values complementary cumulative distribution function (CCDF) to evaluate the receiver‐side antennas correlation effect and the outcomes of the appropriate antennas usage, showing some results for a 4 × 4 MIMO channel with linearly and uniformly spaced antennas.
Analogue circuit design methodology using self‐cascode structures
Authors: Baek K.‐J. , Gim J.‐M. , Kim H.‐S. , Na K.‐Y. , Kim N.‐S. , Kim Y.‐S. 
Published: June 2013

A new analogue circuit design methodology using independently optimised self‐cascode (SC) structures is proposed. Based on the concept of the dual‐workfunction‐gate structures, which are equivalent to SC structures, transconductance and output resistance optimised SC MOSFETs were used in the differential input and output stages, respectively. An operational amplifier (opamp) with the proposed design methodology using standard 0.18 µm CMOS technology was designed to provide better performance. The measured DC gain of the fabricated opamp with independently‐optimised SC MOSFETs was approximately 12 dB higher than that of the conventional opamp.
Nakagami‐m approximations for multiple‐input multiple‐output singular value decomposition transmissions
Authors: Rosas Fernando , Oberli Christian 
Published: June 2013

The multiple‐input multiple‐output singular value decomposition (MIMO SVD) modulation is an efficient way of sending data through a multi‐antenna communications link in which the transmitter has knowledge of the channel state. Despite its importance, no simple formula for its symbol error rate (SER) has been found, and hence no intuitive characterisation of the quality of this technique for data transmission is available at the present. In this study, the authors present a method for approximating the statistics of each eigenchannel of MIMO SVD using the Nakagami‐m fading model. Using the proposed method, it is seen that the SER of the entire MIMO SVD link can be approximated by the average of the SER of Nakagami‐m channels. The expression found is simple and yet accurate. This leads to characterise the eigenchannels of N × N MIMO channels with N larger than 14, showing that the smallest eigenchannel distributes as a Rayleigh channel, the next four eigenchannels closely distributes as Nakagami‐m channels with m = 4, 9, 25 and 36, and the N − 5 remaining eigenchannels have statistics similar to an additive white Gaussian noise (AWGN) channel within 1 dB signal‐to‐noise ratio. It is also shown that 75% of the total mean power gain of the MIMO SVD channel goes to the top third of all the eigenchannels.

Exploration of conformational transition pathways from coarse-grained simulations
Authors: Sfriso Pedro , Hospital Adam , Emperador Agustí , Orozco Modesto 
Published: June 2013

Abstract
Motivation: A new algorithm to trace conformational transitions in proteins is presented. The method uses discrete molecular dynamics as engine to sample protein conformational space. A multiple minima Go-like potential energy function is used in combination with several enhancing sampling strategies, such as metadynamics, Maxwell Demon molecular dynamics and essential dynamics. The method, which shows an unprecedented computational efficiency, is able to trace a wide range of known experimental transitions. Contrary to simpler methods our strategy does not introduce distortions in the chemical structure of the protein and is able to reproduce well complex non-linear conformational transitions. The method, called GOdMD, can easily introduce additional restraints to the transition (presence of ligand, known intermediate, known maintained contacts, …) and is freely distributed to the community through the Spanish National Bioinformatics Institute (http://mmb.irbbarcelona.org/GOdMD).

Assisted design of linkage‐driven adaptive soft fingers
Authors: Larouche Louis‐Alain , Birglen Lionel 
Published: June 2013

PurposeAdaptive grippers are versatile end effectors that mechanically adapt their shapes to the objects they seize, allowing for soft and delicate grasps while still allowing for strong contact forces if needed and therefore they are well suited for industrial applications. The purpose of this paper is to present a software‐oriented approach to design optimal architectures of linkage‐driven adaptive (often a.k.a underactuated) fingers with three degrees of freedom.Design/methodology/approachThe user of the software presented in this paper can design planar underactuated fingers following defined constraints. The software uses an algorithm able to compute the internal and contact forces generated, respectively, in and by the finger, it is also capable of automating the design of non‐straight links to eliminate mechanical interferences, and includes results from a topological synthesis to generate all possible architectures. The mechanisms are evaluated for many criteria such as the volume of their workspaces, stability, force isotropy, stiffness of their grasps, and compactness.FindingsThis article introduces 11 new designs of underactuated fingers for four different usages, and many of these variants are good candidates for a physical realization. One of the interesting results of this work is the recurrence of S3 variants coupled with torque amplifiers or closely resembling designs using many unrelated performance criteria.Originality/valueThis paper is the first, to the best of the authors' knowledge, to investigate the systematic design of underactuated fingers driven by linkages considering not one but dozens of mechanical architectures.
