Authors: An Junmo , Webb Andrew G. , Shah Dipan J. , Chin Karen , Tsekos Nikolaos V. 
Published: June 2017

AbstractBackgroundA method for the identification of semi‐active fiducial magnetic resonance (MR) markers is presented based on selectively optically tuning and detuning them.MethodsFour inductively coupled solenoid coils with photoresistors were connected to light sources. A microcontroller timed the optical tuning/detuning of coils and image collection. The markers were tested on an MR manipulator linking the microcontroller to the manipulator control to visibly select the marker subset according to the actuated joint.ResultsIn closed‐loop control, the average and maximum were 0.76° ± 0.41° and 1.18° errors for a rotational joint, and 0.87 mm ± 0.26 mm and 1.13 mm for the prismatic joint.ConclusionsThis technique is suitable for MR‐compatible actuated devices that use semi‐active MR‐compatible markers.
A decoupled designing approach for sampling consensus of multi‐agent systems
Authors: Liu Yongfang , Zhao Yu , Chen Guanrong 
Published: June 2017

SummaryThis paper introduces the motion‐planning approaches to solve the distributed consensus problems via sampling measurements. First, for first‐order multiagent systems, a class of sampled‐data–based algorithms are developed with arbitrary sampling periods, which solve the asymptotic consensus problem under both directed fixed and random switching topologies. Then, a new kind of distributed consensus algorithms is designed based on sampling measurements for second‐order multiagent systems. Under both the directed fixed and periodical switching topologies, asymptotic consensus problems of second‐order multiagent systems can be solved by using the proposed algorithms. Compared with existing continuous‐time consensus algorithms, one of remarkable advantages of proposed algorithms is that the sampling periods, communication topologies, and control gains are decoupled and can be separately designed, which relaxes many restrictions in controller designs. Finally, some numerical examples are given to illustrate the effectiveness of the analytical results.
Assessing the impact of Volatile Functionality removal in web applications: Model‐Driven vs Code‐Based approaches
Authors: Urbieta M. , Frajberg D. , Rossi G. 
Published: June 2017

SummaryWeb applications must quickly adapt to new business demands to keep clients onboard. When unexpected and unforeseen requirements appear, the changes pose challenges to software engineers as they were not considered in the application design and such new functionality can be only valid only for a period in certain situations.This work presents a comparison of maintenance consequences in the software quality when using a Model‐Driven approach against a Code‐Based one where changes are managed in an ad hoc way. We used the removal of volatile functionality as case of study due to the fact that its characteristics stress the development process. We considered both external and internal quality of deliverables.For assessing the quality of deliverables, we evaluated the production of more than 35 students using both approaches considering their perception gathered through questionnaires and their deliverables.We present the preliminary evidence that there is no significant difference between approaches. Model‐Driven performed slightly better than Code‐Based, but both responded negatively in terms of deliverables' quality. Results show that maintenance tasks are detrimental to software quality where Model‐Driven approach does not excel over Code‐Based approach. The Model‐Driven approach only highlighted on productivity.

Published: June 2017

SummarySoftware reliability growth models support the prediction/assessment of product quality, release time, and testing/debugging cost. Several software reliability growth model extensions take into account the bug correction process. However, their estimates may be significantly inaccurate when debugging fails to fully fit modelling assumptions. This paper proposes debugging‐workflow‐aware software reliability growth method (DWA‐SRGM), a method for reliability growth analysis leveraging the debugging data usually managed by companies in bug tracking systems. On the basis of a characterization of the debugging workflow within the software project under consideration (in terms of bug features and treatment phases), DWA‐SRGM pinpoints the factors impacting the estimates and to spot bottlenecks, thus supporting process improvement decisions. Two industrial case studies are presented, a customer relationship management system and an enterprise resource planning system, whose defects span a period of about 17 and 13 months, respectively. DWA‐SRGM revealed effective to obtain more realistic estimates and to capitalize on the awareness of critical factors for improving debugging.

The Normative Authority of Social Practices: A Critical Theoretical Reading of Hegel’s Introduction to thePhilosophy of Right
Authors: Lima Erick 
Published: June 2017

AbstractWhat follows is an attempt to interpret Hegel’s Introduction to thePhilosophy of Rightin a way that explores the thesis of reason’s social character in light of the recent debate on Hegel’s theory of practical normativity. The discussion aims to highlight Hegel’s commitment to a ‘reconstructive’ version of the ‘immanent transcendence’ motive of Critical Theory and, more generally, to a programmatic critique of ‘deficient’ rationality and its effects on practice.
An unknown Phanerozoic driver of brachiopod extinction rates unveiled by multivariate linear stochastic differential equations
Authors: Reitan Trond , Liow Lee Hsiang 
Published: June 2017

AbstractWhether the evolutionary dynamics of one group of organisms influence that of another group of organisms over the vast timescale of the geological record is a difficult question to tackle. This is not least because multiple factors can influence or mask the effects of potential driving forces on evolutionary dynamics of the focal group. Here, we show how an approach amenable to causality inference for time series, linear stochastic differential equations (SDEs), can be used in a multivariate fashion to shed light on driving forces of diversification dynamics across the Phanerozoic. Using a new, enhanced stepwise search algorithm, we searched through hundreds of models to converge on a model that best describes the dynamic relationships that drove brachiopod and bivalve diversification rates. Using this multivariate framework, we characterized a slow process (half-life of c. 42 Myr) that drove brachiopod extinction. This slow process has yet to be identified from the geological record. Using our new framework for analyzing multiple linear SDEs, we also corroborate our previous findings that bivalve extinction drove brachiopod origination in the sense that brachiopods tended to diversify at a greater rate when bivalves were removed from the system. It is also very likely that bivalves “self-regulate” in the sense that bivalve extinctions also paved the way for higher bivalve origination rates. Multivariate linear SDEs as we presented them here are likely useful for studying other dynamic systems whose signatures are preserved in the paleontological record.
Ixodes kangdingensis (Acari: Ixodidae), a new species from the Siberian weasel, Mustela sibirica (Carnivora: Mustelidae) in China
Authors: GUO TIANYU , SUN YI , XU GUANG , DURDEN LANCE A. 
Published: June 2017

SUMMARY
The female and nymph of Ixodes (Pholeoixodes) kangdingensis n. sp. are described based on both morphology and analysis of 16S rRNA gene sequences. Specimens of this new tick species were collected from a Siberian weasel (Mustela sibirica) in Kangding County, Sichuan Province, China. The morphological features of the female and nymph are unique to distinguish I. kangdingensis n. sp. from other members of the subgenus Pholeoixodes, including the presence of distinctly shaped cornua, anterior and posterior processes on palpal article I and a large angular projection on each side of the hypostome. Partial sequence of 16S rRNA gene grouped this species with Ixodes arboricola and Ixodes lividus with sequence divergence of new species from I. arboricola 4·16% and from I. lividus 8·49%. Data on the phylogenetic position, hosts, geographic distribution and key to females of closely related species are also provided.
Radiocarbon Dating of Barrows of the Pazyryk, Karakoba, and Bystrianka Cultures from the Manzherok Region, Russia
Authors: Borodovskiy Andriey P , Krąpiec Marek , Oleszczak Łukasz 
Published: June 2017

AbstractThis paper presents radiocarbon (14C) dating of Scythian period sites discovered in Northern Altai, Russia, in the 1990s, including large, unlooted barrow cemeteries in the Manzherok region. The results indicate that barrows attributed to the Karakoba culture may represent a long time span from the beginning of the 9th century BC until the beginning of 1st century BC, while those linked with the North Pazyryk culture generally keep within the Scythian period: from the beginning of the 5th century BC to the late 1st century AD. 14C analysis has confirmed the viability of traditional archaeological dating and the contemporaneity of barrows belonging to various cultural traditions (North Pazyryk, Karakoba), and also allowed correlating the horizons of burials to the seismic phenomena observed at the site.
Women's Legislative Underrepresentation: Enough Come Forward, (Still) Too Few Chosen
Authors: Ashe Jeanette 
Published: June 2017

AbstractNo established liberal democracy has achieved sex balance in its national legislature. Scholars agree skewed candidate pools put forward by parties during elections cause sex-disproportionate seat distribution, but disagree as to whether disproportionality is caused by too few women aspirant candidates coming forward (supply) or party selectors preferring men (demand). This paper uses a multistage method to explore supply and demand during the British Labour party's candidate selection process. Rare data from three elections and 4622 aspirants allow for an unobstructed look inside the secret garden of politics and reveal the party is not fully feminized insofar that women aspirants are disproportionally filtered out of its selection process and are disproportionally underrepresented in its candidate pool. Testing reveals a lack of selector demand for women aspirants has a greater impact on women's underrepresentation than an undersupply of women aspirants, a finding which supports using sex quotas to level imbalanced candidate slates.
Composing music, developing dialogues: An enactive perspective on children's collaborative creativity
Authors: Veloso Ana Luísa 
Published: June 2017

This study aims to provide new insights on the nature of the embodied and collaborative processes related to the emergence of new musical ideas that occur when children are composing in groups.Data was obtained by participant observation of the teacher/researcher and by ten videotaped one-hour musical sessions dedicated to the development of a music composition by two groups of children, all of whom were eight years old.It was found that when composing in groups a) children use embodied processes to transform what they experience on diverse realms of their existence into musical ideas, and that b) while creating music, children engage in several improvisatory moments where new ideas emerge through the diverse ways they enact the surroundings where the activity is occurring. Findings suggest a conception of music composing as a multidimensional phenomenon that entails cognitive processes that are distributed across and beyond the physical body. Findings also suggest that composing music in collaboration with others nurtures a set of creative possibilities that would otherwise, not occur. Considerations for music education theory and practice are addressed in the last section of the article.
Changing Property-Rights Regimes: A Study of Rural Land Tenure in China
Authors: Brandt Loren , Whiting Susan H. , Zhang Linxiu , Zhang Tonglong 
Published: June 2017

AbstractThrough two rounds of land contracting, rural households have been allocated a bundle of rights in land. We observe significant differences across villages in the amount of land to which villagers retain a claim and the institutional mechanisms governing the exchange of land rights. This study reveals the perpetuation and expansion of non-market mechanisms accruing to the benefit of village cadres and state officials and only limited emergence of market mechanisms in which households are primary beneficiaries. It identifies factors in economic, political and legal domains that incentivize and enable state officials and local cadres to capture returns from use of land. Relatedly, the study finds differences in conflict over property-rights regimes. Drawing on a pilot survey carried out by the authors in November of 2011 in Shaanxi and Jiangsu provinces (192 households in 24 villages), this paper seeks to explain heterogeneity and change in property-rights regimes over time and across space.
Clingcon: The next generation
Authors: BANBARA MUTSUNORI , KAUFMANN BENJAMIN , OSTROWSKI MAX , SCHAUB TORSTEN 
Published: June 2017

AbstractWe present the third generation of the constraint answer set systemclingcon, combining Answer Set Programming (ASP) with finite domain constraint processing (CP). While its predecessors rely on a black-box approach to hybrid solving by integrating the CP solvergecode, the newclingconsystem pursues a lazy approach using dedicated constraint propagators to extend propagation in the underlying ASP solverclasp. No extension is needed for parsing and groundingclingcon's hybrid modeling language since both can be accommodated by the new generic theory handling capabilities of the ASP groundergringo. As a whole,clingcon3 is thus an extension of the ASP systemclingo5, which itself relies on the groundergringoand the solverclasp. The new approach ofclingconoffers a seamless integration of CP propagation into ASP solving that benefits from the whole spectrum ofclasp's reasoning modes, including, for instance, multi-shot solving and advanced optimization techniques. This is accomplished by a lazy approach that unfolds the representation of constraints and adds it to that of the logic program only when needed. Although the unfolding is usually dictated by the constraint propagators during solving, it can already be partially (or even totally) done during preprocessing. Moreover,clingcon's constraint preprocessing and propagation incorporate several well-established CP techniques that greatly improve its performance. We demonstrate this via an extensive empirical evaluation contrasting, first, the various techniques in the context of CSP solving and, second, the newclingconsystem with other hybrid ASP systems.
The Christian Hermeneutics of Cranmer’s Homilies
Authors: Briggs Richard S. 
Published: June 2017

AbstractThis article explores some of the hermeneutical resources of the two official books of homilies, authorized to be preached in the BCP communion service. The historical contexts and successive editions of the books are explained, and a focused reading is offered of the key texts relevant to the interpretation of Scripture. Some consideration is given to other related texts that highlight Cranmer’s hermeneutical approach. It is suggested that Cranmer’s use of Scripture is not in practice the approach he commends in the first homily, but is driven by concerns with attaining the ‘right’ doctrine of justification. A key issue is the interplay between readerly character, deferral to wise readers, and the pressure of the text against particular traditions. It is argued that the Books of Homilies here offer rich material for reflection upon the nature of Christian hermeneutics in one particular ecclesial tradition, and indicate an Anglican approach to Scripture that has much to offer.

AbstractTumor necrosis factor-related apoptosis-inducing ligand (TRAIL) can selectively kill tumor cells. TRAIL resistance in cancers is associated with aberrant expression of the key components of the apoptotic program. However, how these components are regulated at the epigenetic level is not understood. In this study, we investigated novel epigenetic mechanisms regulating TRAIL response in glioblastoma multiforme (GBM) cells by a short-hairpin RNA loss-of-function screen. We interrogated 48 genes in DNA and histone modification pathways and identified KDM2B, an H3K36-specific demethylase, as a novel regulator of TRAIL response. Accordingly, silencing of KDM2B significantly enhanced TRAIL sensitivity, the activation of caspase-8, -3 and -7 and PARP cleavage. KDM2B knockdown also accelerated the apoptosis, as revealed by live-cell imaging experiments. To decipher the downstream molecular pathways regulated by KDM2B, levels of apoptosis-related genes were examined by RNA-sequencing upon KDM2B loss, which revealed derepression of proapoptotic genes Harakiri (HRK), caspase-7 and death receptor 4 (DR4) and repression of antiapoptotic genes. The apoptosis phenotype was partly dependent on HRK upregulation, as HRK knockdown significantly abrogated the sensitization. KDM2B-silenced tumors exhibited slower growth in vivo. Taken together, our findings suggest a novel mechanism, where the key apoptosis components are under epigenetic control of KDM2B in GBM cells.

Published: June 2017

AbstractRho GTPases control fundamental cellular processes and Cdc42 is a well-studied member of the family that controls filopodia formation and cell migration. Although the regulation of Cdc42 activity by nucleotide binding is well documented, the mechanisms driving its proteostasis are not clear. Here, we demonstrate that the highly conserved, RING domain containing E3 ubiquitin ligase XIAP controls the protein stability of Cdc42. XIAP binds to Cdc42 and directly conjugates poly ubiquitin chains to the Lysine 166 of Cdc42 targeting it for proteasomal degradation. Depletion of XIAP led to an increased protein stability and activity of Cdc42 in normal and tumor cells. Consistently, loss of XIAP enhances filopodia formation in a Cdc42-dependent manner and this phenomenon phenocopies EGF stimulation. Further, XIAP depletion promotes lung colonization of tumor cells in mice in a Cdc42-dependent manner. These observations shed molecular insights into ubiquitin-dependent regulation of Cdc42 and that of actin cytoskeleton.

AbstractCadherin linkages between adjacent stereocilia and microvilli are essential for mechanotransduction and maintaining their organization. They are anchored to actin through interaction of their cytoplasmic domains with related tripartite complexes consisting of a class VII myosin and adaptor proteins: Myo7a/SANS/Harmonin in stereocilia and Myo7b/ANKS4B/Harmonin in microvilli. Here, we determine high-resolution structures of Myo7a and Myo7b C-terminal MyTH4-FERM domain (MF2) and unveil how they recognize harmonin using a novel binding mode. Systematic definition of interactions between domains of the tripartite complex elucidates how the complex assembles and prevents possible self-association of harmonin-a. Several Myo7a deafness mutants that map to the surface of MF2 disrupt harmonin binding, revealing the molecular basis for how they impact the formation of the tripartite complex and disrupt mechanotransduction. Our results also suggest how switching between different harmonin isoforms can regulate the formation of networks with Myo7a motors and coordinate force sensing in stereocilia.

AbstractSodium-ion batteries operating at ambient temperature hold great promise for use in grid energy storage owing to their significant cost advantages. However, challenges remain in the development of suitable electrode materials to enable long lifespan and high rate capability. Here we report a sodium super-ionic conductor structured electrode, sodium vanadium titanium phosphate, which delivers a high specific capacity of 147 mA h g−1 at a rate of 0.1 C and excellent capacity retentions at high rates. A symmetric sodium-ion full cell demonstrates a superior rate capability with a specific capacity of about 49 mA h g−1 at 20 C rate and ultralong lifetime over 10,000 cycles. Furthermore, in situ synchrotron diffraction and X-ray absorption spectroscopy measurement are carried out to unravel the underlying sodium storage mechanism and charge compensation behaviour. Our results suggest the potential application of symmetric batteries for electrochemical energy storage given the superior rate capability and long cycle life.
Controlling heat and particle currents in nanodevices by quantum observation
Authors: Biele Robert , Rodríguez-Rosario César A. , Frauenheim Thomas , Rubio Angel 
Published: June 2017

AbstractWe demonstrate that in a standard thermo-electric nanodevice the current and heat flows are not only dictated by the temperature and potential gradient, but also by the external action of a local quantum observer that controls the coherence of the device. Depending on how and where the observation takes place, the direction of heat and particle currents can be independently controlled. In fact, we show that the current and heat flow in a quantum material can go against the natural temperature and voltage gradients. Dynamical quantum observation offers new possibilities for the control of quantum transport far beyond classical thermal reservoirs. Through the concept of local projections, we illustrate how we can create and directionality control the injection of currents (electronic and heat) in nanodevices. This scheme provides novel strategies to construct quantum devices with application in thermoelectrics, spintronic injection, phononics, and sensing among others. In particular, highly efficient and selective spin injection might be achieved by local spin projection techniques.
