AbstractOur current knowledge of star formation and accretion luminosity at high redshift (z> 3–4), as well as the possible connections between them, relies mostly on observations in the rest-frame ultraviolet, which are strongly affected by dust obscuration. Due to the lack of sensitivity of past and current infrared instrumentation, so far it has not been possible to get a glimpse into the early phases of the dust-obscured Universe. Among the next generation of infrared observatories,SPICA, observing in the 12–350 µm range, will be the only facility that can enable us to trace the evolution of the obscured star-formation rate and black-hole accretion rate densities over cosmic time, from the peak of their activity back to the reionisation epoch (i.e., 3 <z≲ 6–7), where its predecessors had severe limitations. Here, we discuss the potential of photometric surveys performed with theSPICAmid-infrared instrument, enabled by the very low level of impact of dust obscuration in a band centred at 34 µm. These unique unbiased photometric surveys thatSPICAwill perform will fully characterise the evolution of AGNs and star-forming galaxies after reionisation.
Quantifying episodic erosion and transient storage on the western margin of the Tibetan Plateau, upper Indus River

Published: November 2017

AbstractTransient storage and erosion of valley fills, or sediment buffering, is a fundamental but poorly quantified process that may significantly bias fluvial sediment budgets and marine archives used for paleoclimatic and tectonic reconstructions. Prolific sediment buffering is now recognized to occur within the mountainous upper Indus River headwaters and is quantified here for the first time using optically stimulated luminescence dating, petrography, detrital zircon U-Pb geochronology, and morphometric analysis to define the timing, provenance, and volumes of prominent valley fills. This study finds that climatically modulated sediment buffering occurs over 103–104yr time scales and results in biases in sediment compositions and volumes. Increased sediment storage coincides with strong phases of summer monsoon and winter westerlies precipitation over the late Pleistocene (32–25 ka) and mid-Holocene (~8–6 ka), followed by incision and erosion with monsoon weakening. Glacial erosion and periglacial frost-cracking drive sediment production, and monsoonal precipitation mediates sediment evacuation, in contrast to the arid Transhimalaya and monsoonal frontal Himalaya. Plateau interior basins, although volumetrically large, lack transport capacity and are consequently isolated from the modern Indus River drainage. Marginal plateau catchments that both efficiently produce and evacuate sediment may regulate the overall compositions and volumes of exported sediment from the Himalayan rain shadow.
A Survey of the 14C Content of Dissolved Inorganic Carbon in Chinese Lakes
Authors: Liu Taibei , Zhou Weijian , Cheng Peng , Burr G S 
Published: November 2017

AbstractWe present radiocarbon (14C) measurements of dissolved inorganic carbon (DIC) from surface waters of 11 lakes, widely distributed in China. Surface lake water DIC F14C values show distinct differences, and we relate these to the physical exchange character (“open” or “closed”) of each lake. Open lakes studied here generally have lower DIC F14C values than closed lakes. We present a simple model of a lake water cycle to calculate an average residence time for each lake. Comparisons between lake DIC F14C and average residence time shows that the DIC F14C increases with the average residence time and reflects a steady-state.
Reservoir Correction for the Central and North Kuril Islands in North Pacific Context
Authors: Fitzhugh Ben , Brown William A 
Published: November 2017

AbstractWe present new marine reservoir ΔR correction terms for the central and northern Kuril Islands. We estimate ΔR from a series of archaeological charcoal-shell pairs from two archaeological sites using standard calibration procedures and Monte Carlo simulation. The combined ΔR estimate for all paired samples for the Kuril samples is 508±127 yr. In the context of available North Pacific Rim ΔR estimates, the new Kuril data support the interpretation of a well-mixed, 14C-depleted North Pacific Subarctic Gyre. For the broader subarctic North Pacific region, a ΔR estimate in the range of 440±127 yr is a reasonable correction for any coastal marine shell date, and may be applied to fish and marine mammal dates for taxa known to reside within these waters throughout their life-histories. This generalization fails as one moves south from Hokkaido along the East Asian coast. There, well-equilibrated subtropical water minimize the ΔR offset.
Influence of Aquatic Plant Photosynthesis on the Reservoir Effect of Genggahai Lake, Northeastern Qinghai-Tibetan Plateau

Published: November 2017

AbstractTerrestrial plant remains in the sediments of lakes from semi-arid and arid regions are rare and therefore the establishment of a sediment chronology depends on accurate assessment of the reservoir effect of the lake water. In a study of Genggahai Lake in the Gonghe Basin, northeastern Qinghai-Tibetan Plateau, we used accelerator mass spectrometry radiocarbon (AMS 14C) dating to determine the age of (1) dissolved inorganic carbon in the water (DICLW), (2) macrophyte remains in the uppermost samples of core sediments, (3) living P. pectinatus in the lake, and (4) dissolved inorganic carbon of spring water in the catchment. The results show that the ages of the DICLW (910 14C yr BP on average) were much younger than the ages of the groundwater (6330 14C yr BP on average), which may result mainly from CO2 exchange between the lake water and the atmosphere. In addition, the 14C ages of DICLW and macrophyte remains in the uppermost core sediments varied from site to site within the lake, which we ascribe to the different photosynthesis rates of Chara spp. and vascular plants. The higher photosynthesis rate of Chara spp. decreases lake-water pCO2, which leads to more atmospheric CO2 being absorbed by the lake water, and thereby greatly reducing the age of carbon species in areas dominated by Chara spp. Although Genggahai Lake is well mixed, the differences between the apparent ages of the lake water are significantly modulated by the photosynthesis intensity of submerged plants.
Pasture intake and grazing behaviour of growing European wild boar (Sus scrofaL.) and domestic pigs (Sus scrofa domesticus, Landrace×Large White) in a semi-extensive production system

SUMMARYThe objective of the present study was to determine the pasture intake of European wild boar and domestic pigs throughout their growth period (from 60 to 207 days of age). The proportion of time that each animal type spent grazing was also determined. Twelve 60-day-old pure-bred European wild boar (six castrated males and six females, average live-weight (±s.e.m.) 6·8 ± 0·37 kg) and 12 70-day-old domestic pigs (Large White × Landrace, six castrated males and six females, average live-weight [ ±s.e.m.] 24·1 ± 0·66 kg) were used in the study. Each day during the study, the animals grazed from 08·00 until 16·00 h, after which they hadad-libitumaccess to a supplemental diet for 1 h. Every 14 days throughout the study (a total of ten determinations), the pasture consumption was determined as the difference between the pasture dry matter (DM) availability pre- and post-grazing. The supplemental diet consumption was also determined. Three times during the study (age of animals 85, 140 and 198 days), the behaviour of each animal was observed over four consecutive days while grazing. When considered on a metabolic bodyweight basis, the pasture consumption of the European wild boar was greater than that in the domestic pigs. Approximately 0·20 of the total DM intake by the wild boar was pasture, whereas only 0·10 of the total DM intake by the domestic pigs was pasture. However, domestic pigs consumed a greater quantity of supplemental diet than the wild boar. The wild boar obtained 0·20 of their total daily dietary apparent energy intake from pasture, compared with 0·07 in the domestic pigs. Wild boar were more active during 8-h grazing periods spending 0·54 of their time grazing or moving around, compared with 0·32 of the time in domestic pigs.
Classification of confectionary sunflower genotypes based on morphological characters

Published: November 2017

SUMMARYKnowledge of genetic diversity of confectionary sunflower can have a large impact on its use in breeding programmes. However, levels and distribution of genetic variation within the confectionary sunflower gene pool are still not adequately explored. The aim of the present paper was to describe the diversity of 68 confectionary sunflower genotypes: open-pollinated varieties, lines and hybrids. A total of 32 morphological traits were used for characterization. The Shannon & Weaver diversity index (H) was estimated as a measure of morphological diversity. The mean value of the Shannon index was 0·71, which indicates a high morphological diversity. The lowest diversity was found for leaf descriptors, moderately high to high for seed traits, while the highest values were found for disc flowers and ray florets. The highest individual descriptor diversity was found for: head attitude, the angle of leaf lateral nerves and ray floret disposition. The homogeneity analysis (HOMALS) multivariate reduction technique for nominal categorical data proved to be an efficient method for a comprehensive overview of genotype diversity and group homogeneity. Besides diversity, the number of categories and uniformity of genotype distribution determines discriminative power of descriptors. Traits that contributed the most to the distinction of genotypes were identified, enabling differentiation of genotypes with similar phenotypic attributes. The highest discriminative power was observed in traits such as anthocyanin colouration of stigma (DFIA), seed colour of stripes and seed main colour. The genotypes tested formed two distinctive major groups of varieties and hybrids with inbred lines widely dispersed along both axes. A separate grouping was obtained per the most discriminative traits based on HOMALS analysis, while the best separation was obtained using DFIA. Isolated genotypes that may not be representative by yield or seed-specific traits can be useful sources of traits for breeding. Morphological characterization can be used to improve description and classification of confectionary sunflower germplasm when evaluating diversity.
A filtration-based rapid test using a partially purified third-stage larval antigen to detect specific antibodies for the diagnosis of gnathostomiasis

Published: November 2017

AbstractHuman gnathostomiasis is an emerging food-borne parasitic disease caused by nematodes of the genusGnathostoma. Currently, serological tests are commonly applied to support clinical diagnosis. In the present study, a simple and rapid filtration-based test, dot immune–gold filtration assay (DIGFA) was developed using a partially purified antigen ofGnathostomathird-stage larvae (L3). A total of 180 serum samples were tested to evaluate the diagnostic potential of DIGFA for gnathostomiasis. The diagnostic sensitivity and specificity were 96.7% (29/30) and 100% (25/25), respectively. The cross-reactivity with sera from other helminthiasis patients ranged from 0 to 4%, with an average of 1.6% (2/125). DIGFA using a partially purified L3 antigen was not only simple and rapid, but also more accurate than standard assays for the diagnosis of human gnathostomiasis. DIGFA may represent a promising tool for application in laboratories or in the field, without requiring any instrumentation.
The ‘Franklins of Colombia’: Immigration Schemes and Hemispheric Solidarity in the Making of a Civilised Colombian Nation
Authors: BASSI ERNESTO 
Published: November 2017

AbstractDuring the 1820s, Colombia's diplomats in London, Washington and Philadelphia worked hard to obtain diplomatic recognition for their nascent republic. Their efforts were also geared towards making Colombia attractive to European and North American settlers whose industry and work ethic would, they hoped, turn it into a civilised and modern Euro-Atlantic nation. The immigration schemes they promoted enable us to understand the type of nations the nation-makers of post-independence Spanish America envisioned and how, by appealing to sentiments of hemispheric solidarity – among other means – they sought to turn their visions into reality. A comparison with similar eighteenth-century schemes promoted by the Bourbons, moreover, reveals the persistence, albeit with some critical modifications, of late-colonial ways of thinking and envisioning society.

AbstractA controversy at the 2016 IUCN World Conservation Congress on the topic of closing domestic ivory markets (the 007, or so-called James Bond, motion) has given rise to a debate on IUCN's value proposition. A cross-section of authors who are engaged in IUCN but not employed by the organization, and with diverse perspectives and opinions, here argue for the importance of safeguarding and strengthening the unique technical and convening roles of IUCN, providing examples of what has and has not worked. Recommendations for protecting and enhancing IUCN's contribution to global conservation debates and policy formulation are given.
Microbial protein targets: towards understanding and intervention
Authors: DENNY PAUL W. 
Published: November 2017

SUMMARYThe rise of antimicrobial resistance, coupled with a lack of industrial focus on antimicrobial discovery over preceding decades, has brought the world to a crisis point. With both human and animal health set to decline due to increased disease burdens caused by near untreatable microbial pathogens, there is an urgent need to identify new antimicrobials. Central to this is the elucidation of new, robustly validated, drug targets. Informed by industrial practice and concerns, the use of both biological and chemical tools in validation is key. In parallel, repurposing approved drugs for use as antimicrobials may provide both new treatments and identify new targets, whilst improved understanding of pharmacology will help develop and progress good ‘hits’ with the required rapidity. In recognition of the need to increase research efforts in these areas, in 14–16 September 2017, the British Society for Parasitology (BSP) Autumn Symposium was hosted at Durham University with the title: Microbial Protein Targets: towards understanding and intervention. Staged in collaboration with the Royal Society of Chemistry (RSC) Chemistry Biology Interface Division (CBID), the core aim was to bring together leading researchers working across disciplines to imagine novel approaches towards combating infection and antimicrobial resistance. Sessions were held on: ‘Anti-infective discovery, an overview’; ‘Omic approaches to target validation’; ‘Genetic approaches to target validation’; ‘Drug target structure and drug discovery’; ‘Fragment-based approaches to drug discovery’; and ‘Chemical approaches to target validation’. Here, we introduce a series of review and primary research articles from selected contributors to the Symposium, giving an overview of progress in understanding antimicrobial targets and developing new drugs. The Symposium was organized by Paul Denny (Durham) for the BSP and Patrick Steel (Durham) for RSC CBID.

AbstractWe agree with Lake and colleagues on their list of “key ingredients” for building human-like intelligence, including the idea that model-based reasoning is essential. However, we favor an approach that centers on one additional ingredient: autonomy. In particular, we aim toward agents that can both build and exploit their own internal models, with minimal human hand engineering. We believe an approach centered on autonomous learning has the greatest chance of success as we scale toward real-world complexity, tackling domains for which ready-made formal models are not available. Here, we survey several important examples of the progress that has been made toward building autonomous agents with human-like abilities, and highlight some outstanding challenges.
Theories or fragments?
Authors: Chater Nick , Oaksford Mike 
Published: November 2017

AbstractLake et al. argue persuasively that modelling human-like intelligence requires flexible, compositional representations in order to embody world knowledge. But human knowledge is too sparse and self-contradictory to be embedded in “intuitive theories.” We argue, instead, that knowledge is grounded in exemplar-based learning and generalization, combined with high flexible generalization, a viewpoint compatible both with non-parametric Bayesian modelling and with sub-symbolic methods such as neural networks.
Building machines that adapt and compute like brains
Authors: Kriegeskorte Nikolaus , Mok Robert M. 
Published: November 2017

AbstractBuilding machines that learn and think like humans is essential not only for cognitive science, but also for computational neuroscience, whose ultimate goal is to understand how cognition is implemented in biological brains. A new cognitive computational neuroscience should build cognitive-level and neural-level models, understand their relationships, and test both types of models with both brain and behavioral data.
If priming is graded rather than all-or-none, can reactivating abstract structures be the underlying mechanism?
Authors: Feldman Laurie Beth , Milin Petar 
Published: November 2017

AbstractIn our commentary on Branigan & Pickering (B&P), we start by arguing that the authors implicitly adopt several assumptions, the consequence of which is to make further claims necessary and/or sufficient. Crucially, the authors assume the existence of discrete units at various levels of linguistic granularity that then must be operated upon by combinatorial mechanisms and rules (i.e., decomposition/recomposition). They further argue that structural priming provides a powerful tool to study abstract, structural representations. We provide evidence that priming effects in production are characterized better as graded than as all-or-none and that priming need not arise from a mechanism that (re)activates a shared but abstract internal structure.
Action sequences instead of representational levels
Authors: Kempson Ruth , Gregoromichelaki Eleni 
Published: November 2017

AbstractDespite enthusiastic agreement that experimental data are directly relevant for determining grammar architecture, we present one main objection to the conclusions that the authors draw from their results: The data are perfectly compatible – in fact, much more in line – with an alternative that does not rely on syntactic representations. Instead, it is processing actions whose activation for comprehension/production explains intra-/inter-speaker priming.
Structural priming is most useful when the conclusions are statistically robust
Authors: Mahowald Kyle , James Ariel , Futrell Richard , Gibson Edward 
Published: November 2017

AbstractBranigan & Pickering (B&P) claim that the success of structural priming as a method should “end the current reliance on acceptability judgments.” Structural priming is an interesting and useful phenomenon, but we are dubious that the effect is powerful enough to test many detailed claims about specific points of syntactic theory.
The malleability of linguistic representations poses a challenge to the priming-based experimental approach
Authors: Ryskin Rachel , Brown-Schmidt Sarah 
Published: November 2017

AbstractRecent findings show that experience with a syntactic structure has long-term consequences for how that structure will be processed in the future, which suggests that linguistic representations are not static entities that can be probed reliably without alteration. Thus, leveraging the effect of previous exposure to a syntactic structure appears to be an inappropriate method for studying invariant properties of language.
Integrated real-time task and motion planning for multiple robots under path and communication uncertainties
Authors: Woosley Bradley , Dasgupta Prithviraj 
Published: November 2017

SUMMARYWe consider a problem where robots are given a set of task locations to visit with coarsely known distances. The robots must find the task ordering that reduces the overall distance to visit the tasks. We propose an abstraction that models the uncertainty in the paths, and a Markov Decision Process-based algorithm that selects paths that reduces the expected distance to visit the tasks. We also describe a distributed coordination algorithm to resolve path conflicts. We have shown that our task selection is optimal, our coordination is deadlock-free, and have experimentally verified our approach in hardware and simulation.
