Facing herbivory on the climb up: Lost opportunities as the main cost of herbivory in the wild yam Dioscorea praehensilis
Authors: Di Giusto Bruno , Dounias Edmond , McKey Doyle B.
Published: July 2017

Plants with simple architecture and strong constraints on their growth may offer critical insights into how growth strategies affect the tolerance of plants to herbivory. Although Dioscorea praehensilis, a wild yam of African forests, is perennial, both aerial apparatus and tuber are annually renewed. Each year, the tuber produces a single stem that climbs from the ground to the forest canopy. This stem bears no leaves and no branches until it reaches optimal light conditions. Once in the canopy, the plant's production fuels the filling of a new tuber before the plant dies back to the ground. We hypothesized that if deprived of ant defense, the leafless growth phase is a vulnerable part of the cycle, during which a small amount of herbivory entails a high cost in terms of loss of opportunity. We compared the growth of stems bearing ants or not as well as of intact stems and stems subjected to simulated or natural herbivory. Ants reduce herbivory; herbivory delays arrival to the canopy and shortens the season of production. Artificially prolonging the stem growth to the canopy increased plant mortality in the following year and, in surviving plants, reduced the stem diameter and likely the underground reserves produced. Tuber size is a key variable in plant performance as it affects both the size of the aerial apparatus and the duration of its single season of production. Aerial apparatus and tuber are thus locked into a cycle of reciprocal annual renewal. Costs due to loss of opportunity may play a major role in plant tolerance to herbivory, especially when architectural constraints interact with ecological conditions to shape the plant's growth strategy.

Authors: Hussain Khalil Khadim , Moon Jong‐Min , Park Deog‐Su , Shim Yoon‐Bo
Published: July 2017

Hemoglobin (Hb) is a tetrameric hemoprotein that is located in red blood cells (RBCs) and is responsible for O2 transport in the circulatory system. Conventionally, Hb assay is a specific and sensitive indicator for the diagnosis of anemia and other related diseases. To date, various methods have been used for the analysis of Hb, and of these, electrochemical method is the simplest and reliable technique. Therefore, several approaches have been reported for the quantification of Hb, including the direct electron transfer (DET) with or without a mediator onto the electrode surface, molecular imprinted polymer (MIPs), and immunoreaction. To realize the direct electrochemistry of Hb, the modification of the electrode surface either with a mediator or catalyst to promote the redox process, which can be applied for the sensitive and selective detection of Hb. This review contains a comprehensive introduction to electrochemical Hb detection methods using modified electrode surfaces. Finally, the review gives a brief insight into the electrochemical sensing platform developed for the analysis of other type of globins such as, myoglobin and glycated hemoglobin. The objectives of this review are to summarize various electrochemical detection methods for Hb and to facilitate future development of new sensing platforms for the medical and healthcare applications.
Evaluation of Nafion with Various Pt–C Concentrations in Membrane Electrode Assemblies for PEMFCs

Published: July 2017

Membrane electrode assemblies (MEAs) were fabricated directly onto the electrolyte membrane, using an ultrasonic spraying technique. Pt–C catalysts, with concentrations of 10%, 20% and 40% by weight, were used, and the Pt loading onto the MEAs was kept constant at 0.3 mg cm−2. Nafion contents were considered from 15% to 35 wt.%. The morphologies of the MEAs were evaluated by scanning electron microscopy (SEM), in which the agglomeration of Pt–C particles was imaged, and a secondary pore in the catalyst layers (CLs) was revealed. The cross‐section images showed that the thickness of the CLs depended on the Pt–C concentration. The electrochemical surface area (ECSA) of those Pt–C concentrations and various compositions of Nafion contents were examined by cyclic voltammetry. Polarization curves were also measured and showed that the Nafion contents of 25 wt.%, 20 wt.%, and 15 wt.% gave the best performance for 10 wt.%, 20 wt.%, and 40 wt.% Pt–C catalysts, respectively. This indicates the Pt concentration is dependent on the Nafion content; the greater the weight of platinum in the catalysts, the less Nafion ionomer is required to optimize the electrochemical reaction. The data shows the same results regardless of the MEA fabrication techniques, operating conditions and Pt loadings.
Influence of Copper‐based Anode Composition on Intermediate Temperature Solid Oxide Fuel Cells Performance
Authors: De Marco V. , Iannaci A. , Lo Faro M. , Sglavo V. M.
Published: July 2017

Planar solid oxide fuel cells (SOFCs), which are intended to be used in the intermediate temperature range (600–800 °C) and whose supporting anode contains various amount of Cu in Li‐doped gadolinia‐doped ceria matrix, are produced and characterized in the present work. Intermediate temperature solid oxide fuel cell (IT‐SOFC) performances are investigated by recording polarization and power density at different temperatures. Electrochemical impedance spectroscopy (EIS) measurements are carried out to analyze how internal resistances change as function of temperature and, above all, for variable Cu content. The gadolinia‐doped ceria electrolyte microstructure and the cell integrity after sintering are also shown to depend on the initial CuO content in the anode. The electronic conductivity increases with Cu content within the anodic cermet. When the anode contains more than 25 vol.% CuO, a dense Li‐doped gadolinia‐doped ceria electrolyte can be obtained by sintering at 900 °C. Conversely, CuO load in excess to 50% in the anode is detrimental because of the formation of macroscopic cracks within the electrolyte. Intermediate temperature solid oxide fuel cells produced with an anodic layer containing 50 vol.% CuO show the lowest impedance parameters.
In vivo THz imaging of human skin: Accounting for occlusion effects
Authors: Sun Qiushuo , Parrott Edward P.J. , He Yuezhi , Pickwell‐MacPherson Emma
Published: July 2017

In vivo terahertz (THz) imaging of human skin needs to be done in reflection geometry due to the high attenuation of THz light by water in the skin. To aid the measurement procedure, there is typically an imaging window onto which the patient places the area of interest. The window enables better pulse alignment and helps keep the patient correctly positioned during the measurement. In this paper, we demonstrate how the occlusion caused by the skin contact with the imaging window during the measurement affects the THz response. By studying both rapid point measurements and imaging over an area of a human volar forearm, we find that even 5 seconds of occlusion affects the THz response. As the occlusion time increases, the skin surface water content increases, resulting in the reduction of the amplitude of the reflected THz pulse, especially in the first 3 minutes. Furthermore, it was found that the refractive index of the volar forearm increased by 10% to 15% after 20 minutes of occlusion. In this work, we examine and propose a model for the occlusion effects due to the quartz window with a view to compensating for its influence.
Capability of the SMHI‐RCA4 RCM driven by the ERA‐Interim reanalysis to simulate heat waves in Argentina
Authors: Collazo Soledad , Lhotka Ondřej , Rusticucci Matilde , Kyselý Jan
Published: July 2017

The aim of the work was to evaluate the capability of the SMHI‐RCA4 regional climate model (RCM) driven by the ERA‐Interim reanalysis to simulate heat waves in Argentina. Firstly, we evaluated simulations of summer daily maximum temperature (Tmax) against observed data from nine stations. The model showed a warm Tmax bias at six locations and the smallest and/or negative biases were located over regions with complex topography. Heat waves were defined based on exceedances of the daily 90th percentile of Tmax at individual stations. The model overestimated the intensity, duration, and number of heat waves at all locations, but more intense heat waves were underestimated. In particular, we analysed the extreme heat wave that occurred in November 1985 in northeastern Argentina and found out that a possible reason for its underestimation was an inaccurate simulation of the sea level pressure gradient in the region. The weaker pressure gradient in the model caused a reduction of the warm northerly advection. Finally, we studied how the parameters of heat waves varied among different phases of El Niño‐Southern Oscillation (ENSO) for observed and modelled data. At five stations, the strongest heat waves occurred during La Niña years and were probably associated with the decrease in precipitation.
Moving towards a wave‐resolved approach to forecasting mountain wave induced clear air turbulence

Published: July 2017

Mountain wave breaking in the lower stratosphere is one of the major causes of atmospheric turbulence encountered in commercial aviation, which in turn is the cause of most weather‐related aircraft incidents. In the case of clear air turbulence (CAT), there are no visual clues and pilots are reliant on operational forecasts and reports from other aircraft. Traditionally mountain waves have been sub‐grid‐scale in global numerical weather prediction (NWP) models, but recent developments in NWP mean that some forecast centres (e.g. the UK Met Office) are now producing operational global forecasts that resolve mountain wave activity explicitly, allowing predictions of mountain wave induced turbulence with greater accuracy and confidence than previously possible. Using a bespoke turbulent kinetic energy diagnostic, the Met Office Unified Model (MetUM) is shown to produce useful forecasts of mountain CAT during three case studies over Greenland, and to outperform the current operational Met Office CAT prediction product (the World Area Forecast Centre (WAFC) London gridded CAT product) in doing so. In a long term, 17‐month, verification, MetUM forecasts yield a turbulence prediction hit rate of 80% with an accompanying false alarm rate of under 40%. These skill scores are a considerable improvement on those reported for the mountain wave component of the WAFC product, although no direct comparison is available. The major implication of this work is that sophisticated global NWP models are now sufficiently advanced to provide skilful forecasts of mountain wave turbulence.

Birkhoff interpolation is the most general interpolation scheme. We study the Lagrange‐type basis for uniform integrable tensor‐product Birkhoff interpolation. We prove that the Lagrange‐type basis of multivariate uniform tensor‐product Birkhoff interpolation can be obtained by multiplying corresponding univariate Lagrange‐type basis when the integrable condition is satisfied. This leads to less computational complexity, which drops to

Published: July 2017

An understanding of the causative mechanisms of the harmful effects of cigarette smoke on the male reproductive system remains incomplete. Here, we investigated three different inhaled cigarette smoke doses over five different exposure durations to identify how the testis is affected. The effects of cigarette smoke exposure on testicular germ cells were characterized by morphological changes and a significant elevation in the number of apoptotic cells. Caspase 3 activation increased dramatically after cigarette smoke exposure, accompanied by significant time‐dependent expression of the pro‐apoptotic proteins Bak (B cell lymphoma/leukemia 2 [Bcl‐2] homologous antagonist killer), Bcl2l11 (a BH3 domain‐only protein related to Bcl‐2), Apaf1 (Apoptotic protease‐activating factor‐1), and Caspase 9. Conversely, the abundance of anti‐apoptotic Bcl2l2 decreased. Taken together, our findings suggest that extensive inhalation of cigarette smoke damages testicular germ cells through the induction of the mitochondrial apoptotic pathway through the Bcl‐2 protein family.
Glucosomes: Glycosylated Vesicle‐in‐Vesicle Aggregates in Water from pH‐Responsive Microbial Glycolipid

Published: July 2017

Vesicle‐in‐vesicle self‐assembled containers, or vesosomes, are promising alternatives to liposomes because of their possible hierarchical encapsulation and high stability. We report herein the first example of sugar‐based vesicles‐in‐vesicles, which we baptize glucosomes. These were prepared by using a natural microbial glycolipid (branched C22 sophorolipid) extracted from the culture medium of the yeast Pseudohyphozyma bogoriensis. Glucosomes spontaneously formed in water between pH 6 and pH 4 at room temperature, without the requirement of any additive. By means of pH‐resolved in situ small angle X‐ray scattering, we provided direct evidence for the vesicle‐formation mechanism. Statistical treatment of the vesicle radii distribution measured by cryo‐tansmission electron microscopy by using a derived form of the Helfrich bending free‐energy expression provided an order of magnitude for the effective bending constant (the sum of the curvature and the saddle‐splay moduli) of the lipid membrane to K=(0.4±0.1) kBT. This value is in agreement with the bending constant measured for hydrocarbon‐based vesicles membranes.
Compensation for state‐dependent nonlinearity in a modified repetitive control system
Authors: Zhou Lan , She Jinhua , Zhou Shaowu , Li Chaoyi
Published: July 2017

This paper presents an estimation and compensation of state‐dependent nonlinearity for a modified repetitive control system. It is based on the equivalent‐input‐disturbance (EID) approach. The nonlinearity is estimated by an EID estimator and compensated by incorporation of the estimate into the repetitive control input. A two‐dimensional model of the EID‐based modified repetitive control system is established that enables the preferential adjustment of control and learning actions by means of 2 tuning parameters. The singular‐value‐decomposition technique and Lyapunov stability theory are used to derive a linear‐matrix‐inequality–based asymptotic stability condition. Exploiting the stability condition and an overall performance evaluation index, a design algorithm is developed. Simulation results for the tracking control of a chuck‐workpiece system show that the method not only compensates state‐dependent nonlinearity but also improves the tracking performance for the periodic reference input, thereby demonstrating the validity of the method.

Computational study on four Acceptor‐Donor‐Acceptor (A–D‐A) type of donor molecules namely, dimethyl cyanoacetate terthiophene di(methylthiophene) benzo[1,2‐b:4,5‐b′]dithiophene (DMCATDMTBDT) (M1), methylrhodanine terthiophene di (methylthiophene) benzo[1,2‐b:4,5‐b′]dithiophene (MRTDMTBDT) (M2), dimethyl cyanoacetate terthiophene di (fluoromethyl thiophene) benzo[1,2‐b:4,5‐b′]dithiophene (DMCATDFMTBDT) (M3), and methylrhodanine terthiophene di (fluoromethyl thiophene) benzo[1,2‐b:4,5‐b′]dithiophene (MRTDFMTBDT) (M4) was carried out and their photovoltaic properties were associated with methyl cyanoacetate terthiophene di (methoxy) benzo[1,2‐b:4,5‐b′]dithiophene (DCAO3TBDT) (R1) and methylrhodanine terthiophene di (methoxy) benzo[1,2‐b:4,5‐b′]dithiophene (DR3TBDT) (R2). For the geometry optimization DFT functional CAM−B3LYP/6‐31G (d) was found to be the best choice, hence TD‐CAM−B3LYP/6‐31G (d) was opted for the calculation of excited state of the molecules. M3 and M4 represented appropriate frontier molecular orbital energy levels and broad absorption band. The reorganization energies of the designed molecules illustrated excellent charge mobility property. The lower λe values as compared to λh illustrate that the designed donor molecules are better electron donors. M4 was found as champion molecules with the lowest λe (0.01601) value. The Voc value of M3 and M4 are 2.74 eV and 2.63 eV respectively with respect to the energy levels of PC60BM (acceptor).

The cancer stem cell (CSC) paradigm suggests that tumors are organized hierarchically. Chugai previously established an LGR5+ human colorectal cancer (CRC) stem-cell-enriched cell line (colorectal CSCs) that expresses well-accepted colorectal CSC markers and that can dynamically switch between proliferative and drug-resistant noncycling states. We performed this study to elucidate the molecular mechanisms responsible for evading cell death in colorectal CSCs mediated by anticancer agents. During the cell cycle arrest caused by anticancer agents, we found that c-Myc expression was substantially decreased in colorectal CSCs. The c-Myc expression alterations were mediated by upregulation of F-box/WD repeat-containing protein 7 (FBXW7), as evidenced through FBXW7-small interfering RNA knockdown experiments that resulted in enhanced cell sensitivity to anticancer agents. Upregulation of FBXW7 following drug treatment was not evident in commercially available cancer cell lines. Colorectal CSCs were induced to differentiation by Matrigel and fetal bovine serum. Differentiated CSCs treated with anticancer agents did not show upregulation of FBXW7 and were more sensitive to irinotecan (CPT-11), highlighting the potential CSC-specific nature of our data. The FBXW7 over-expression was further validated in resected liver metastatic sites in CRC patients after chemotherapy. In conclusion, our study revealed that a CSC-specific FBXW7-regulatory mechanism is strongly associated with resistance to chemotherapeutic agents. Inhibition of FBXW7-upregulation in CSCs following chemotherapy may enhance the response to anticancer agents and represents an attractive strategy for the elimination of colorectal CSCs.
Geometrically non‐linear elastic model for a thin composite layer with wavy surfaces
Authors: Kalamkarov A. L. , Tornabene F. , Pacheco P. M. C. L. , Savi M. A. , Saha G. C.
Published: July 2017

The geometrically non‐linear elastic thin composite layer model is developed through the application of the modified asymptotic homogenization method. The set of local unit cell problems and the analytical formulae for the effective stiffness moduli of the non‐linear homogenized plate accounting the higher order terms of the asymptotic expansions are derived. They make it possible to gain useful insight into the manner in which the geometrical and mechanical properties of the individual constituents affect the elastic properties of the composite layer with wavy surfaces. It is shown that in the limiting case of a homogeneous layer of constant thickness the derived asymptotic homogenization model converges to the geometrically non‐linear mean‐flexure plate theory. And the obtained expressions for the mid‐surface strains converge to von Kármán's formulae. The derived non‐linear homogenization model is illustrated by an example of a laminated plate.

Aspergillus section Aspergillus (formerly the genus Eurotium) includes xerophilic species with uniseriate conidiophores, globose to subglobose vesicles, green conidia and yellow, thin walled eurotium-like ascomata with hyaline, lenticular ascospores. In the present
study, a polyphasic approach using morphological characters, extrolites, physiological characters and phylogeny was applied to investigate the taxonomy of this section. Over 500 strains from various culture collections and new isolates obtained from indoor environments and a wide range of
substrates all over the world were identified using calmodulin gene sequencing. Of these, 163 isolates were subjected to molecular phylogenetic analyses using sequences of ITS rDNA, partial β-tubulin (BenA), calmodulin (CaM) and RNA polymerase II second largest subunit (RPB2)
genes. Colony characteristics were documented on eight cultivation media, growth parameters at three incubation temperatures were recorded and micromorphology was examined using light microscopy as well as scanning electron microscopy to illustrate and characterize each species. Many specific
extrolites were extracted and identified from cultures, including echinulins, epiheveadrides, auroglaucins and anthraquinone bisanthrons, and to be consistent in strains of nearly all species. Other extrolites are species-specific, and thus valuable for identification. Several extrolites show
antioxidant effects, which may be nutritionally beneficial in food and beverages. Important mycotoxins in the strict sense, such as sterigmatocystin, aflatoxins, ochratoxins, citrinin were not detected despite previous reports on their production in this section. Adopting a polyphasic approach,
31 species are recognized, including nine new species. ITS is highly conserved in this section and does not distinguish species. All species can be differentiated using CaM or RPB2 sequences. For BenA, Aspergillus brunneus and A. niveoglaucus share identical
sequences. Ascospores and conidia morphology, growth rates at different temperatures are most useful characters for phenotypic species identification.
Germany's Empire in the East
Authors: Hamlin David
Published: July 2017

This book puts German policy toward Romania and the German East into a global context. One of the signal events of the twentieth century was Germany's effort to construct an empire in Europe modeled on the European experience outside Europe. The turn to European empire resulted less from the dynamics of capitalist expansion than from a deep crisis in global political and economic order. Confronted with the global economic and political power of the western allies, the Germans turned to Eastern Europe to construct a dependent space, tied to Germany as Central America was to the US. The First World War transformed how Germans thought about international order, empire and the nature of Romanians. The domestic consequences of Germany's eviction from global markets authorized deep interventions in Romanian society to establish a pre-eminent position for the German state inside Romania. David Hamlin embeds occupation and war aims in economic concerns.
Coolies of the Empire
Authors: Kumar Ashutosh
Published: July 2017

This book studies Indian overseas labour migration in the nineteenth and early twentieth centuries, which involved millions of Indians traversing the globe in the age of empire, subsequent to the abolition of slavery in 1833. This migration led to the presence of Indians and their culture being felt all over the world. This study delves deep into the lives of these indentured workers from India who called themselves girmitiyas; it is a narrative of their experiences in India and in the sugar colonies abroad. It foregrounds the alternative world view of the girmitiyas, and their socio-cultural and religious life in the colonies. In this book, the author has developed highly original insights into the experience of colonial indentured migrant labour, describing the ways in which migrants managed to survive and even flourish within the interstices of the indentured labour system and how considerably the experience of migration changed over time.
Drug Wars
Authors: Feldman Robin , Frondorf Evan
Published: July 2017

While the shockingly high prices of prescription drugs continue to dominate the news, the strategies used by pharmaceutical companies to prevent generic competition are poorly understood, even by the lawmakers responsible for regulating them. In this groundbreaking work, Robin Feldman and Evan Frondorf illuminate the inner workings of the pharmaceutical market and show how drug companies twist health policy to achieve goals contrary to the public interest. In highly engaging prose, they offer specific examples of how generic competition has been stifled for years, with costs climbing into the billions and everyday consumers paying the price. Drug Wars is a guide to the current landscape, a roadmap for reform, and a warning of what is to come. It should be read by policymakers, academics, patients, and anyone else concerned with the soaring costs of prescription drugs.
THE REACH OF THE MILITARY: TANG
Authors: Graff David A.
Published: July 2017

During the Tang period (618–907), war and the preparations for war significantly influenced the shape of the Chinese empire and the lives of its people. That influence can be found on at least four levels. The first of these is the state’s demand for military service, which imposed a variety of burdens upon a significant percentage of the population. The second is the state’s demand for cash, fabric, grain and other financial and material resources to meet the needs of the military establishment, a demand that affected the whole of the taxpaying population. Third is the loss and destruction caused directly by warfare, especially massive internal conflicts such as the rebellions of An Lushan and Huang Chao. Fourth, and most far-reaching and diffuse, is the range of cultural reactions to military affairs, from the emphatic embrace of martial attitudes and behaviors to their emphatic rejection.

CLAIMS AGAINST THIRD-PARTY RECIPIENTS OF TRUST PROPERTY
Authors: Salmons David
Published: July 2017

This article argues that claims to recover trust property from third parties arise in response to a trustee's duty to preserve identifiable property, and that unjust enrichment is incompatible with such claims. First, unjust enrichment can only assist with the recovery of abstract wealth and so it does not assist in the recovery of specific property. Second, it is difficult to identify a convincing justification for introducing unjust enrichment. Third, it will work to the detriment of innocent recipients. The article goes on to show how Re Diplock supports this analysis, by demonstrating that no duty of preservation had been breached and that a proprietary claim should not have been available in that case. The simple conclusion is that claims to recover specific property and claims for unjust enrichment should be seen as mutually exclusive.
PULLING A TRIGGER OR STARTING A JOURNEY? BREXIT IN THE SUPREME COURT
Authors: Feldman David
Published: July 2017

FOLLOWING a referendum on 23 June 2016 in which 52% of voters (38% of the total electorate) had expressed a preference for the UK to leave the EU, the Government announced that it would start the process of withdrawal, in accordance with Article 50 of the Treaty on European Union (“TEU”), by notifying the European Council of the UK's decision, exercising the Government's prerogative power to conduct foreign relations. A number of legal challenges were fast-tracked to the Supreme Court. In R. (Miller) v Secretary of State for Exiting the European Union (Birnie and others intervening) [2017] UKSC 5; [2017] 2 W.L.R. 583 after an expedited hearing, the Court decided two issues: (1) whether the Government could exercise its power under the royal prerogative to give notice, or needed an Act of Parliament to authorise the giving of notice; and (2) whether the Government required the consent of devolved legislatures in Northern Ireland, Scotland and Wales before giving notice or introducing to Parliament a Bill authorising the giving of notice. The Court sat unprecedentedly with all 11 serving members. On issue (1), the Court, by an 8–3 majority, held that an Act of Parliament would be required in order to authorise the giving of notice. On issue (2), the Court unanimously held that there was no legal requirement for consent by the devolved institutions.
THE RECOVERY OF GAINS FROM A FIDUCIARY'S MISUSE OF TRUST FUNDS
Authors: Devonshire Peter
Published: July 2017

SUPPOSE a trustee misapplies trust funds to purchase property for his own benefit. If the acquired property increases in value, what is the nature of the beneficiaries’ claim in respect of those gains? This was recently considered by the Hong Kong Court of Final Appeal in Tang v Tang [2017] HKCFA 3. In 2003 the administrator of an estate (the defendant) purchased property (the “Property”). The purchase was partly funded by the unauthorised use of HK $11.48 m from the estate. Shortly afterwards, the defendant executed a declaration of trust over the Property in favour of his corporate vehicle, Tri-Strong Investment Ltd. The Property was subsequently transferred to this company. Seven months after acquiring the Property, the defendant paid the estate the full amount that had been withdrawn together with interest. In 2005 the estate beneficiaries discovered the defendant's misuse of estate money and commenced proceedings alleging breach of fiduciary duty. By the time the matter was heard, the Property had increased significantly in value.
JUSTIFIABLE DISCRIMINATION: THE CASE OF OPPOSITE-SEX CIVIL PARTNERSHIPS
Authors: Hayward Andy
Published: July 2017

OPPOSITE-SEX couples are prohibited from forming a civil partnership. Following the introduction of same-sex marriage, the Civil Partnership Act 2004 was not extended to opposite-sex couples, resulting in the unusual position that English law permits same-sex couples access to two relationship forms (marriage and civil partnership) yet limits opposite-sex couples to one (marriage). This discrimination was recently challenged in the courts by an opposite-sex couple, Rebecca Steinfeld and Charles Keidan, who wish to enter a civil partnership owing to their deeply-rooted ideological opposition to marriage. Rejecting marriage as a patriarchal institution and believing that a civil partnership would offer a more egalitarian public expression of their relationship, the couple argued that the current ban constitutes a breach of Article 14 read in conjunction with Article 8 of the European Convention on Human Rights.

The End of Bare Life?
Authors: NOLAN RACHEL ELIN
Published: July 2017

Since Giorgio Agamben's influential critique of the liberal-democratic state, scholars have offered a more fulsome engagement with the ways that this formation extends Foucauldian biopolitical discourses by foregrounding the emergence of biological existence as “the new political subject.” InHomo Sacer: Sovereign Power and Bare LifeAgamben argues that it is impossible to understand the development, vocation, and contradictions of the modern state “if one forgets that what lies at its basis is not man as a free and conscious political subject, but, above all, man's bare life, the simple birth that as such is, in the passage from subject to citizen, invested in the principle of sovereignty.” Bare or pure life is the human as animal in nature without political definition or mediation. It is the isolation of the metaphysical from the various forms of concrete life that defines and conditions Western politics. Projects that imagine political communities as grounded in belonging or endeavor to found political rights in the citizen are in vain. The figure of thehomo sacer – the “sacred man” who “may be killed and yet not sacrificed” – is one of the most distinctive elements of Agamben's project of redefining sovereignty in biopolitical terms. Contra notions of collective political sovereignty as the basis of state politics, the figure of thehomo sacerattends to a more authoritarian model that pivots on the role of state authorities in simultaneously conditioning and dis/avowing the movement from bare life to rights-bearing subject.

Sequences of the first and second internal transcribed spacers (ITS1 + ITS2) of nuclear ribosomal DNA were employed to determine whether the congeneric assemblages of species of the strongyloid nematode genusCloacina, found in the forestomachs of individual species of kangaroos and wallabies (Marsupialia: Macropodidae), considered to represent species flocks, were monophyletic. Nematode assemblages examined in the black-striped wallaby,Macropus(Notamacropus)dorsalis, the wallaroos,Macropus(Osphranter)antilopinus/robustus, rock wallabies,Petrogalespp., the quokka,Setonix brachyurus,and the swamp wallaby,Wallabia bicolor,were not monophyletic and appeared to have arisen by host colonization. However, a number of instances of within-host speciation were detected, suggesting that a variety of methods of speciation have contributed to the evolution of the complex assemblages of species present in this genus.
Phylogeny and morphology ofOvipleistophora diplostomurin. sp. (Microsporidia) with a unique dual-host tropism for bluegill sunfish and the digenean parasitePosthodiplostomum minimum(Strigeatida)

Microsporidia are diverse opportunistic parasites abundant in aquatic organisms with some species hyperparasitic in digenean parasites. In the current study, we describe a unique microsporidian parasite,Ovipleistophora diplostomurin. sp. that has a tropism for both the bluegill sunfishLepomis macrochirus, and its digenean parasitePosthodiplostomum minimum. Though the microsporidium first infects a fish, the subsequent infection causes hypertrophy of the metacercarial wall and degeneration of theP. minimummetacercariae within the fish tissue. Genetic analysis placed this species withinOvipleistophoraand ultrastructural characteristics were consistent with the genus, including the presence of dimorphic spores within sporophorous vesicles. Meronts did not have a surface coat of dense material, which has been previously reported for the genus. This is the firstOvipleistophoraspecies described that does not have a tropism for ovary. Genetics demonstrated thatO. diplostomurin. sp. groups closely within fish microsporidia and not other species known to be hyperparasitic in digeneans, suggesting that it evolved from fish-infecting microsporidians and developed a secondary tropism for a common and widespread digenean parasite. The high genetic identity toOvipleistophoraspecies demonstrates the close relationship of this unique microsporidian with other microsporidia that infect ovary.
Captain William Adams senior: whaling Master
Authors: Begg Hugh M. , Watson John

Captain William Adams (1837–1890) was one of the exceptional whaling masters who sailed from Dundee in Scotland. This paper uses primary sources to confirm his reputation not only as a whaler but also as an adventurous explorer and wealthy businessman. He became outstandingly successful with Alexander Stephen & Sons, the Dundee shipping company that pioneered the use of auxiliary powered vessels for use in sealing in Labrador and fishing for whales in the Davis Strait and beyond. His first command was the Arctic in 1868, and his reputation was such that he was chosen by Albert Hastings Markham as his mentor in gaining experience for polar exploration. The unfortunate loss of the Arctic in Regent Sound in 1875 did no damage to this reputation and Adams was made Master of the newly built flagship of the company's fleet, the Arctic II. In 1883, by then a rich man, Adams became his own Master with the purchase of the Maud. In 1890, the vessel was returning to Dundee from Arctic waters when Captain Adams, who was accompanied by his son also William Adams (1869–1942) acting as Mate, was taken fatally ill, dying at Thurso in Caithness.
Irrational “Coefficients” in Renaissance Algebra
Authors: Oaks Jeffrey A.
Published: July 2017

Argument

From the time of al-Khwārizmī in the ninth century to the beginning of the sixteenth century algebraists did not allow irrational numbers to serve as coefficients. To multiply$\sqrt {18} $byx, for instance, the result was expressed as the rhetorical equivalent of$\sqrt {18{x^2}} $. The reason for this practice has to do with the premodern concept of a monomial. The coefficient, or “number,” of a term was thought of as how many of that term are present, and not as the scalar multiple that we work with today. Then, in sixteenth-century Europe, a few algebraists began to allow for irrational coefficients in their notation. Christoff Rudolff (1525) was the first to admit them in special cases, and subsequently they appear more liberally in Cardano (1539), Scheubel (1550), Bombelli (1572), and others, though most algebraists continued to ban them. We survey this development by examining the texts that show irrational coefficients and those that argue against them. We show that the debate took place entirely in the conceptual context of premodern, “cossic” algebra, and persisted in the sixteenth century independent of the development of the new algebra of Viète, Decartes, and Fermat. This was a formal innovation violating prevailing concepts that we propose could only be introduced because of the growing autonomy of notation from rhetorical text.
Loudspeakers Optional: A history of non-loudspeaker-based electroacoustic music
Authors: Long Jason , Murphy Jim , Carnegie Dale , Kapur Ajay

The discipline of electroacoustic music is most commonly associated with acousmatic musical forms such as tape-music and musique concrète, and the electroacoustic historical canon primarily centres around the mid-twentieth-century works of Pierre Schaeffer, Karlheinz Stockhausen, John Cage and related artists. As the march of technology progressed in the latter half of the twentieth century, alternative technologies opened up new areas within the electroacoustic discipline such as computer music, hyper-instrument performance and live electronic performance. In addition, the areas of electromagnetic actuation and musical robotics also allowed electroacoustic artists to actualise their works with real-world acoustic sound-objects instead of or along side loudspeakers. While these works owe much to the oft-cited pioneers mentioned above, there exists another equally significant alternative history of artists who utilised electric, electronic, pneumatic, hydraulic and other sources of power to create what is essentially electroacoustic music without loudspeakers. This article uncovers this ‘missing history’ and traces it to its earliest roots over a thousand years ago to shed light on often-neglected technological and artistic developments that have shaped and continue to shape electronic music today.

Abstract.The relationship between Hashimoto’s thyroiditis and vitamin D has been demonstrated in several studies. The aim of the present study was to evaluate vitamin D concentrations in patients with Hashimoto’s thyroiditis, the effect of vitamin D therapy on the course of disease, and to determine changes in thyroid autoantibody status and cardiovascular risk after vitamin D therapy. We included 75 patients with Hashimoto’s thyroiditis and 43 healthy individuals. Vitamin D deficiency is defined as a 25-hydroxy vitamin D (25(OH)D3) concentration less than 20ng/mL. Vitamin D deficient patients were given 50.000 units of 25(OH)D3 weekly for eight weeks in accordance with the Endocrine Society guidelines. All evaluations were repeated after 2 months of treatment. Patients with Hashimoto’s thyroiditis had significantly lower vitamin D concentrations compared with the controls (9.37±0.69 ng/mL vs 11.95±1.01 ng/mL, p < 0.05, respectively). Thyroid autoantibodies were significantly decreased by vitamin D replacement treatment in patients with euthyroid Hashimoto’s thyroiditis. Also, HDL cholesterol concentrations improved in the euthyroid Hashimoto group after treatment. The mean free thyroxine (fT4) concentrations were 0.89±0.02 ng/dL in patients with Hashimoto’s thyroiditis and 1.07±0.03 ng/dL in the healthy control group (p < 0.001). The mean thyroid volumes were 7.71±0.44 mL in patients with Hashimoto’s thyroiditis and 5.46±0.63 mL in the healthy control group (p < 0.01). Vitamin D deficiency is frequent in Hashimoto’s thyroiditis and treatment of patients with this condition with Vitamin D may slow down the course of development of hypothyroidism and also decrease cardiovascular risks in these patients. Vitamin D measurement and replacement may be critical in these patients.

Abstract. Although suffering is a central issue in pain, there is only little research on this topic. The aim of this study was to assess suffering in an experimental context using various stimulation methods and durations, and to examine which psychological or psychophysiological measures covary with pain-related suffering. Twenty-one healthy volunteers participated in two experiments in which we used tonic thermal and phasic electric stimuli with short and long stimulus durations. The participants rated pain intensity, unpleasantness, and pain-related suffering on separate visual analog scales (VAS) and completed the Pictorial Representation of Illness and Self Measure (PRISM), originally developed to assess suffering in chronic illness. We measured heart rate, skin conductance responses (SCRs), and the electromyogram (EMG) of the musculus corrugator supercilii. For both heat and electric pain, we obtained high ratings on the suffering scale confirming that suffering can be evoked in experimental pain conditions. Whereas pain intensity and unpleasantness were highly correlated, both scales were less highly related to suffering, indicating that suffering is distinct from pain intensity and unpleasantness. Higher suffering ratings were associated with more pronounced fear of pain and increased private self-consciousness. Pain-related suffering was also related to high resting heart rate, increased SCR, and decreased EMG during painful stimulation. These results offer an approach to the assessment of suffering in an experimental setting using thermal and electric pain stimulation and shed light on its psychological and psychophysiological correlates.

Abstract. Traumatic exposure is particularly devastating for those who, at a young age, have become combatants or experienced massive adversity after abduction by armed movements. We investigated the impact of traumatic stressors on psychopathology among war-affected young men of Northern Uganda, including former child soldiers. Adaptation to violent environments and coping with trauma-related symptoms often result in an increasing appetite for violence. We analyze implicit attitudes toward violence, assessed by an Implicit Association Test (IAT), among 64 male participants. Implicit attitudes varied as a function of the number of experienced traumatic event types and committed offense types. As the number of traumatic experiences and violence exposure increased, more appetitive aggression was reported, whereas the IAT indicated increasingly negative implicit attitudes toward aggression. The IAT was also the strongest predictor of cortisol levels. Diffusion-model analysis was the best way to demonstrate IAT validity. Implicit measures revealed the trauma-related changes of cognitive structures.
