Output feedback relay control in the second‐order sliding mode context with application to an electropneumatic system
Authors: Yan Xinming , Primot Muriel , Plestan Franck 
Published: November 2016

SummaryIn this paper, a new second‐order sliding mode output feedback control law is proposed. It amounts to approach the dynamic performance of the twisting algorithm, but the main advantage of this new control method is that it requires only the information of the sliding variable, and not its derivative. A gain adaptation law is also developed for this new control law. Then this control strategy is applied to the position control of an electropneumatic system, and its performance is compared with other two very recent adaptive second‐order sliding mode control laws.

Robust power optimization scheme for cooperative wireless relay system in smart city
Authors: Liu Zhixin , Zhang Peng , Lam Hak‐Keung , Chan Kit Yan , Ma Kai 
Published: November 2016

SummaryUltra dense deployment of base stations is one of most significant features in smart city communication networks. Aiming at the large‐scale wireless communication issue in smart city, we propose a distributed robust power allocation scheme with proportional fairness for cooperative orthogonal frequency‐division‐multiple‐access relay network. With the amplify‐and‐forward relay mode, all of the relays assist the information transmission simultaneously on orthogonal subcarriers. Considering the uncertainty of channel gains, first we aim at achieving the maximum utility subject to the constraints of outage probability threshold and power bound. Subsequently, the problem is transformed to a solvable convex optimization problem with determination constraints. The dual‐decomposition method is applied to solve the formulated optimization problem. To reduce the information exchange of the whole system, we propose a computationally efficient distributed iteration algorithm. Numerical results reveal the effectiveness of the proposed robust optimization algorithm. Copyright © 2016 John Wiley & Sons, Ltd.
Deriving bisimulation relations from path based equivalence checkers
Authors: Banerjee Kunal , Sarkar Dipankar , Mandal Chittaranjan 
Published: November 2016

Abstract
Translation validation is an undecidable problem. Bisimulation relation based approaches, nevertheless, have been widely successful in translation validation of programs albeit with some drawbacks. These drawbacks include non-termination of the verification methodology and significant restrictions on the structures of programs to be checked for equivalence. We have developed a path based equivalence checker which propagates mismatched values over consecutive paths to alleviate these drawbacks. In this work, we show how a bisimulation relation between a program and its translated version can be constructed from the outputs of such a value propagation based equivalence checker. Moreover, none of the earlier methods that establish equivalence through construction of bisimulation relations has been shown to tackle code motions across loops; the present work demonstrates, for the first time, the existence of a bisimulation relation under such a situation.
Global range expansion of pest Lepidoptera requires socially acceptable solutions

Published: November 2016

AbstractCaterpillars of key moth pests can cause significant losses in cropping systems worldwide, and globalization is spreading such pests. Failure to control some species can jeopardise the economics of food production. A Global Eradication and Response Database (http://b3.net.nz/gerda) was reviewed on known government-level incursion response programs specific to invasive Lepidoptera. Geographic range expansion of Lepidoptera was evident from 144 incursion response programs targeting 28 species in 10 families. The countries involved in responses to Lepidoptera were USA (104), Australia (8), Canada (7), New Zealand (6), Italy (3), Mexico (2), with the remainder with one programme each (Brazil, Czech Republic, France, Hungary, and Spain). Most programs have been undertaken since the 1990’s. Control options exist for the long-term management of Lepidoptera, but most have issues of cost, efficacy or non-target impacts that reduce their acceptance. Pheromone-based technologies are increasingly available and are generally highly compatible with other tactics. The development of tactics for new targets is a major undertaking, although previous programs can be invaluable. New and improved socially-acceptable technologies are needed to counteract range expansion in Lepidoptera, and usually need to be used in combinations to achieve eradication. The sterile insect technique, which involves mass-rearing and release of sterile insects to reduce wild populations of the pest, has been used successfully against a number of lepidopteran species. Several sterile moth programs are under development. New technologies must have a social license to operate in urban areas, where new incursions are frequently detected. This factor is likely to reduce tactical flexibility and increase the complexity of insect eradication.
Randomized Controlled Trial of Hyalobarrier® Versus No Hyalobarrier® on the Ovulatory Status of Women with Periovarian Adhesions: A Pilot Study
Authors: Cheong Ying , Bailey Sarah , Forbes Jane 
Published: November 2016

Abstract
Introduction
Periadnexal adhesions are known to contribute to subfertility. The restoration of the tubo-ovarian anatomy is one the key principles in reproductive surgery, and this involves adhesiolysis. However, adhesion formation/reformation is very common after periovarian adhesiolysis. It is not known if the application of Hyalobarrier®, an anti-adhesion gel, around the adnexal region postsurgery influences ovulatory status. The study is a pilot randomized controlled trial (RCT) randomizing women into the application of Hyalobarrier® versus no Hyalobarrier® at the time of laparoscopy, where postsurgical ovulatory status and pregnancy rates were evaluated.

Methods
This was a pilot RCT where women were recruited from the gynecological and subfertility clinic who were deemed to require an operative laparoscopy. If intraoperatively they were found to have periovarian adhesions, they were randomized into having adhesiolysis with and without usage of Hyalobarrier®. Demographic details and intraoperative details including the severity, extent, and the ease of use of Hyalobarrier® were recorded. Prior to the surgery and postoperatively, the participants had their serum hormonal status (day 2 FSH, LH and day 21 progesterone) evaluated. Postoperatively, they underwent a follicular tracking cycle at 3 months.

Results
Fifteen women were randomized into use of Hyalobarrier® (study group) and 15 into the no Hyalobarrier® group (control group) between December 2011 and January 2014. There was no difference in the patient characteristics in terms of age, BMI, the number of previous pregnancies, or the extent, site, and severity of adhesions between the two groups. There was no significant difference between the study versus control groups in terms of the hormonal profile (day 2 FSH and day 21 progesterone) before or after surgery. The 3-month postoperative day 10–12 follicular tracking findings and endometrial thickness were similar between the study and control groups. Four women were pregnant in the study group (24%) and one in the control group (7%) cumulatively over 2 years.

Conclusion
The use of Hyalobarrier® post salpingo-ovariolysis did not influence follicular development as inferred from the results of the day 21 progesterone and folliculogram on day 10–12 3-month postsurgery.

Intravenous fluids: balancing solutions
Authors: Hoorn Ewout J. 
Published: November 2016

AbstractThe topic of intravenous (IV) fluids may be regarded as “reverse nephrology”, because nephrologists usually treat to remove fluids rather than to infuse them. However, because nephrology is deeply rooted in fluid, electrolyte, and acid-base balance, IV fluids belong in the realm of our specialty. The field of IV fluid therapy is in motion due to the increasing use of balanced crystalloids, partly fueled by the advent of new solutions. This review aims to capture these recent developments by critically evaluating the current evidence base. It will review both indications and complications of IV fluid therapy, including the characteristics of the currently available solutions. It will also cover the use of IV fluids in specific settings such as kidney transplantation and pediatrics. Finally, this review will address the pathogenesis of saline-induced hyperchloremic acidosis, its potential effect on outcomes, and the question if this should lead to a definitive switch to balanced solutions.
Aspergillus is monophyletic: Evidence from multiple gene phylogenies and extrolites profiles

Aspergillus is one of the economically most important fungal genera. Recently, the ICN adopted the single name nomenclature which has forced mycologists to choose one name for fungi (e.g. Aspergillus, Fusarium, Penicillium, etc.). Previously two proposals
for the single name nomenclature in Aspergillus were presented: one attributes the name “Aspergillus” to clades comprising seven different teleomorphic names, by supporting the monophyly of this genus; the other proposes that Aspergillus is a non-monophyletic
genus, by preserving the Aspergillus name only to species belonging to subgenus Circumdati and maintaining the sexual names in the other clades. The aim of our study was to test the monophyly of Aspergilli by two independent phylogenetic analyses using a multilocus phylogenetic
approach. One test was run on the publicly available coding regions of six genes (RPB1, RPB2, Tsr1, Cct8, BenA, CaM), using 96 species of Penicillium, Aspergillus and related taxa. Bayesian (MrBayes) and Ultrafast Maximum Likelihood (IQ-Tree)
and Rapid Maximum Likelihood (RaxML) analyses gave the same conclusion highly supporting the monophyly of Aspergillus. The other analyses were also performed by using publicly available data of the coding sequences of nine loci (18S rRNA, 5,8S rRNA, 28S rRNA (D1-D2), RPB1, RPB2,
CaM, BenA, Tsr1, Cct8) of 204 different species. Both Bayesian (MrBayes) and Maximum Likelihood (RAxML) trees obtained by this second round of independent analyses strongly supported the monophyly of the genus Aspergillus. The stability test also confirmed
the robustness of the results obtained. In conclusion, statistical analyses have rejected the hypothesis that the Aspergilli are non-monophyletic, and provided robust arguments that the genus is monophyletic and clearly separated from the monophyletic genus Penicillium. There is no
phylogenetic evidence to split Aspergillus into several genera and the name Aspergillus can be used for all the species belonging to Aspergillus i.e. the clade comprising the subgenera Aspergillus, Circumdati, Fumigati, Nidulantes, section Cremei and certain
species which were formerly part of the genera Phialosimplex and Polypaecilum. Section Cremei and the clade containing Polypaecilum and Phialosimplex are proposed as new subgenera of Aspergillus. The phylogenetic analysis also clearly shows that Aspergillus
clavatoflavus and A. zonatus do not belong to the genus Aspergillus. Aspergillus clavatoflavus is therefore transferred to a new genus Aspergillago as Aspergillago clavatoflavus and A. zonatus was transferred to Penicilliopsis
as P. zonata. The subgenera of Aspergillus share similar extrolite profiles indicating that the genus is one large genus from a chemotaxonomical point of view. Morphological and ecophysiological characteristics of the species also strongly indicate that Aspergillus
is a polythetic class in phenotypic characters.
The changing landscape of oropharyngeal cancer management
Authors: Hamilton D , Khan M K , O'hara J , Paleri V 
Published: November 2016

AbstractBackground:Oropharyngeal cancer is increasing in prevalence in the UK and this is thought to be due to the emergence of disease related to human papilloma virus.Method:A literature review was conducted on the diagnosis and latest management of oropharyngeal cancer.Results:In non-smokers, human papilloma virus related disease is thought to have better outcomes, but this casts doubt on previous research which did not stratify patients according to human papilloma virus status. However, this theory provides a route for researchers to risk stratify and de-escalate treatments, and hence reduce treatment burden. In addition, the emergence of minimally invasive transoral techniques allows surgeons to remove large tumours without many of the side effects associated with radical (chemo)radiotherapy.Conclusion:The emergence of human papilloma virus related disease and minimally invasive techniques have led the clinical and academic community to reconsider how oropharyngeal cancer is managed. Comparative and risk-stratification trials are urgently required and ongoing.
Autologous intratympanic blood patch for presumed perilymphatic fistulas
Authors: Foster P K 
Published: November 2016

AbstractObjective:To assess an alternative to bed rest and surgery for suspected perilymphatic fistulas using intratympanic blood injections.Method:A review was conducted of patients’ history, physical and audiometric data, before and after treatment by intratympanic blood injections performed from 2009 to 2015.Results:Twelve ears were identified, with trauma associated with air travel, water sports or nose blowing. Ten of these cases had hearing loss, six had vestibular symptoms. Four cases had audiological and vestibular symptoms, two had vestibular symptoms only, and six had audiological symptoms only. Time-to-treat varied from 1 day to 30 days. Magnetic resonance imaging scans were obtained for five cases. Ten cases received steroids. Six out of seven cases showed improvement of hearing loss. Five cases showed positive fistula test results, four with documented resolution. Seven cases had full resolution of all symptoms, four had near-full resolution and one had no improvement.Conclusion:Intratympanic blood injections offer an effective alternative to conservative or surgical therapy. Advantages include sooner time-to-treat, lower financial costs and decreased psychosocial burdens. It allows a more flexible and liberal use of a potential definite treatment for perilymphatic fistula.

Published: November 2016

SUMMARYNew drugs againstTrypanosoma brucei,the causative agent of Human African Trypanosomiasis, are urgently needed to replace the highly toxic and largely ineffective therapies currently used. The trypanosome alternative oxidase (TAO) is an essential and unique mitochondrial protein in these parasites and is absent from mammalian mitochondria, making it an attractive drug target. The structure and function of the protein are now well characterized, with several inhibitors reported in the literature, which show potential as clinical drug candidates. In this review, we provide an update on the functional activity and structural aspects of TAO. We then discuss TAO inhibitors reported to date, problems encountered within vivotesting of these compounds, and discuss the future of TAO as a therapeutic target.
An attention and interpretation bias for illness-specific information in chronic fatigue syndrome
Authors: Hughes A. M. , Chalder T. , Hirsch C. R. , Moss-Morris R. 
Published: November 2016

BackgroundStudies have shown that specific cognitions and behaviours play a role in maintaining chronic fatigue syndrome (CFS). However, little research has investigated illness-specific cognitive processing in CFS. This study investigated whether CFS participants had an attentional bias for CFS-related stimuli and a tendency to interpret ambiguous information in a somatic way. It also determined whether cognitive processing biases were associated with co-morbidity, attentional control or self-reported unhelpful cognitions and behaviours.MethodA total of 52 CFS and 51 healthy participants completed self-report measures of symptoms, disability, mood, cognitions and behaviours. Participants also completed three experimental tasks, two designed specifically to tap into CFS salient cognitions: (i) visual-probe task measuring attentional bias to illness (somatic symptoms and disability) v. neutral words; (ii) interpretive bias task measuring positive v. somatic interpretations of ambiguous information; and (iii) the Attention Network Test measuring general attentional control.ResultsCompared with controls, CFS participants showed a significant attentional bias for fatigue-related words and were significantly more likely to interpret ambiguous information in a somatic way, controlling for depression and anxiety. CFS participants had significantly poorer attentional control than healthy individuals. Attention and interpretation biases were associated with fear/avoidance beliefs. Somatic interpretations were also associated with all-or-nothing behaviour and catastrophizing.ConclusionsPeople with CFS have illness-specific biases which may play a part in maintaining symptoms by reinforcing unhelpful illness beliefs and behaviours. Enhancing adaptive processing, such as positive interpretation biases and more flexible attention allocation, may provide beneficial intervention targets.

BackgroundIt has been demonstrated that negatively distorted self-referential processing, in which individuals evaluate one's own self, is a pathogenic mechanism in subthreshold depression that has a considerable impact on the quality of life and carries an elevated risk of developing major depression. Behavioural activation (BA) is an effective intervention for depression, including subthreshold depression. However, brain mechanisms underlying BA are not fully understood. We sought to examine the effect of BA on neural activation during other perspective self-referential processing in subthreshold depression.MethodA total of 56 subjects underwent functional magnetic resonance imaging scans during a self-referential task with two viewpoints (self/other) and two emotional valences (positive/negative) on two occasions. Between scans, while the intervention group (n = 27) received BA therapy, the control group (n = 29) did not.ResultsThe intervention group showed improvement in depressive symptoms, increased activation in the dorsal medial prefrontal cortex (dmPFC), and increased reaction times during other perspective self-referential processing for positive words after the intervention. Also, there was a positive correlation between increased activation in the dmPFC and improvement of depressive symptoms. Additionally, there was a positive correlation between improvement of depressive symptoms and increased reaction times.ConclusionsBA increased dmPFC activation during other perspective self-referential processing with improvement of depressive symptoms and increased reaction times which were associated with improvement of self-monitoring function. Our results suggest that BA improved depressive symptoms and objective monitoring function for subthreshold depression.
Receipt of informal care in the Chinese older population
Authors: HU BO , MA SAI 
Published: November 2016

ABSTRACTThis paper examines the factors affecting the receipt of informal care among older people in China. It uses the second wave data of the China Health and Retirement Longitudinal Survey, which collected ageing and health-related information on a nationally representative sample of 8,906 older people aged 60 and over in 2013. Apart from the factors that have been examined in the contexts of developed countries, the paper further investigates two factors specific to Chinese society: rural–urban residence and regular financial assistance from children. Based on binary and multinomial logit regression analyses, the research findings are threefold: the determinants of receiving informal care differ remarkably according to the sources of care; disability and living arrangements are the most important determinants; rural–urban residence plays a vital role in the Chinese context, but regular financial assistance from children makes little difference. It is estimated that 53 million older people are receiving informal care each year, a figure equivalent to the entire population of England. With continuous population ageing, Chinese society will face huge pressure to meet the demand for social care among older people in the future. The Chinese government needs to build a well-rounded welfare system that tackles this challenge from multiple dimensions. The formal care services should aim to complement informal care in the short run and reduce inequality in social care in the long run.
Changed prevalence, not absence, explains toothfish status in McMurdo Sound

AbstractWe comment on the conjecture by Parkeret al. (2016) that Antarctic toothfish recently returned to McMurdo Sound, arguing that this species never departed. Instead, as deduced from a 40-year fishing effort, toothfish water column prevalence became markedly reduced where bottom depths are <500 m, with research continuing to show their presence on the bottom or above the bottom where depths are deeper. We also counter arguments that toothfish departed, and remained absent, during and following a five-year presence of mega-icebergs residing near the opposite coast of Ross Island, the icebergs inhibiting or fomenting conditions that discouraged toothfish presence in the Sound. Available analyses reveal that toothfish movement into the Sound was probably not significantly affected, and additionally that neither changes in hydrography nor in primary productivity in the Sound would have been sufficient to impact toothfish presence through food web alteration. We hypothesize that the local effect of predation by seals and whales and the regional effect of a fishery targeting the largest toothfish (those neutrally buoyant and thus capable of occupying upper levels of the water column) has resulted in the remaining toothfish now being found predominantly closer to the bottom at greater depths.
