AbstractObjectiveTo describe seafood consumption patterns in First Nations (FN) in British Columbia (BC) and examine lifestyle characteristics associated with seafood consumption; to identify the top ten most consumed seafood species and their contributions to EPA and DHA intake; and to estimate dietary exposure to methylmercury, polychlorinated biphenyls and dichlorodiphenyldichloroethylene.DesignDietary and lifestyle data from the First Nations Food Nutrition and Environment Study, a cross-sectional study of 1103 FN living in twenty-one communities across eight ecozones in BC, Canada, were analysed. Seafood consumption was estimated using a traditional FFQ. Seafood samples were analysed for contaminant contents.ResultsSeafood consumption patterns varied significantly across BC ecozones reflecting geographical diversity of seafood species. The top ten most consumed species represented 64 % of total seafood consumption by weight and contributed 69 % to the total EPA+DHA intake. Mean EPA+DHA intake was 660·5 mg/d in males, 404·3 mg/d in females; and 28 % of FN met the Recommended Intake (RI) of 500 mg/d. Salmon was the most preferred species. Seafood consumption was associated with higher fruit and vegetable consumption, lower smoking rate and increased physical activity. Dietary exposure to selected contaminants from seafood was negligible.ConclusionsIn FN in BC, seafood continues to be an essential part of the contemporary diet. Seafood contributed significantly to reaching the RI for EPA+DHA and was associated with a healthier lifestyle. Given numerous health benefits, seafood should be promoted in FN. Efforts towards sustainability of fishing should be directed to maintain and improve access to fisheries for FN.
Adding a new perspective to US agricultural trade policy
Authors: Mercier Stephanie 
Published: September 2018

AbstractUS farmers and ranchers have actively pursued markets in foreign countries for their products since the 1970s. This priority was reflected by the US Congress in 1978 enacting the first set of laws establishing programs aimed at promoting US agricultural exports. In 1986, the US government initiated its first trade negotiations, with the government of Canada, with the express goal of liberalizing access in that market to all US food and agricultural exports. Since that time, the US government has completed free trade agreements with 20 countries, six in DR-CAFTA, 13 in bilateral agreements and adding Mexico to create NAFTA. The US government also devotes considerable resources to detecting and combatting unfair barriers to trade, through informal channels as well as through WTO dispute settlements. However, these tools primarily focus on capturing larger slices of existing markets. To generate better returns, we need to focus more energy on efforts to generate increased demand in developing countries, by helping their agricultural economies prosper. Once those economies are growing, the other tools can be utilized.

Abstract. The Dirty Dozen scale is a short measure developed to assess the Dark Triad traits, namely Machiavellianism, psychopathy, and narcissism, which has previously shown good psychometric properties. The aim of this study was to validate a Spanish version of the Dirty Dozen through the assessment of its psychometric properties in a sample constituted by 326 young adults aged 18–34 ( M = 20.55; SD = 1.89) from Spain. The Spanish version of the Dirty Dozen showed good internal consistency and acceptable test-retest stability. Likewise, the analysis of the factorial structure supported the three-factor solution and showed a best fit for the bifactorial model. The latent factor of the general Dark Triad was associated with low levels of Honesty/Humility, psychopathic traits, impulsivity, and sensation seeking; whereas a differential pattern of associations between the three specific Dark Triad latent factors and the nomological network was found. Furthermore, the Dark Triad traits showed differential relations with reactive and proactive aggression, verifying the external validity of the Spanish version of the Dirty Dozen. Results support the distinctiveness of the Dark Triad traits and justify the Dirty Dozen as an efficient measure for dark personalities in Spanish-speaking contexts.

Published: September 2018

AbstractResearchers have long suspected a source‐to‐sink link between the Yangtze Block (and/or North China Block) and Eocene‐Miocene passive margin strata in Taiwan, and various models have been proposed to explain similarities in provenance and the presence of Archean grains. The East China Sea Shelf Basin, whose evolution has been neglected in most models, resides between potential mainland China source regions and the sediment sink in Taiwan, and occupies the corridor through which sediment would have been transported. Here we present 378 new concordant detrital zircon U–Pb ages from the Oligocene Huagang formation in the Xihu Sag, eastern East China Sea Shelf Basin. We also present a compilation of published detrital zircon data from major rivers across mainland China to evaluate potential sediment source regions. Detrital zircons in the Huagang formation range in age from 33 ± 0.4 to 2842 ± 43 Ma, with major clusters at 100–300 and 1,600–2,200 Ma and small early‐middle Paleozoic, Neoproterozoic, and Paleoproterozoic to Archean peaks. Visual and statistical comparison of age distributions suggest close relationships between the Min River and Eocene–Oligocene samples from western Taiwan and between the Oligocene Huagang formation and Miocene strata in western Taiwan. Combined with the tectonic and depositional evolution of the region, these observations suggest that Eocene–Oligocene sediments in Taiwan were mainly sourced from the Min River or similar drainage in the Cathaysia Block. However, the similarities between the Huagang formation and Miocene strata are best explained by reworking of the Oligocene sediment in the Xihu Sag and transportation to western Taiwain during Miocene tectonic inversion of the East China Sea Shelf Basin.

Published: September 2018

AbstractUpper‐ocean submesoscale fronts, with their associated strong vertical velocities, are often claimed to play a significant role in subducting tracers into the interior. The role of these submesoscale processes in restratifying the mixed layer is now well recognized, but whether they simultaneously flux tracers through the base of the boundary layer remains an open question. We vary the resolution in a semirealistic channel model to control turbulent processes at various scales and study their influence on tracers. It is found that the submesoscale‐permitting simulations flux far more tracer downward than the lower‐resolution simulations: The 1‐km simulation takes up 50% more tracer compared to the 20‐km simulation, despite the increased restratifying influence of the resolved submesoscale processes. A full frequency‐wave number cross‐spectra of the vertical velocity and vertical tracer flux show that the high‐frequency inertia‐gravity waves that appear in the highest‐resolution simulation play no role in irreversible downward tracer transport.

AbstractThe identification of Late Carboniferous (317 ± 3 Ma) Daixi‐Wufenglou S‐type granites and Early Triassic (247 ± 2 Ma) Houzhang complex (comprising monzodiorite and monzogranite) in southeast China provides new insights into the bewildering tectonics of south China, before its final welding to the Eurasian continent. The Daixi‐Wufenglou granites have high K2O (4.01–6.54 wt%), A/CNK (1.02–1.34), high bulk initial 87Sr/86Sr (0.7094–0.7160) and low εNd(t) (−8.87 to −6.31), and low zircon εHf(t) (−8.1 to −1.9) and high δ18O (12.7–14.0‰), indicating derivation by partial melting of a Neoproterozoic basement as a result of the input of mantle‐derived heat in a back‐arc extensional setting, triggered by rollback of the Paleo‐Pacific plate subduction beneath the outboard proto‐Japan arc. The monzodiorites are shoshonitic, characterized by high K, Ni, Cr, and Mg#, and the monzogranites are adakitic, defined by high Sr/Y, (La/Yb)n and low Y, Yb. They have similar 87Sr/86Sr (0.7085–0.7087), εNd(t) (−5.92 to −5.34), and εHf(t) (−7.5 to −2.5), indicating their petrogenetic linkage. The monzodiorites and monzogranites represent early crystallization phases (cumulates) and residual melts of a mantle‐derived magma, generated from a metasomatically enriched mantle. Integrating these data with other geological information from south China and neighboring countries, we propose a new model for the tectonic evolution of the Late Paleozoic south China, which was controlled by the subduction of the Paleo‐Pacific Ocean plate. A distal continental back‐arc setting was produced by slab rollback in the early stages, and an active continental margin environment was produced by the accretion of the proto‐Japan arc in the later stages.

AbstractWe present detailed photometric properties of the Moon at far ultraviolet wavelengths. The far ultraviolet data from the Lunar Reconnaissance Orbiter (LRO) Lyman Alpha Mapping Project (LAMP) instrument were used to derive two Hapke photometric parameters, the single‐scattering albedo, w, and the asymmetry factor, b, in the single‐particle phase function, for selected mare and highland regions. The derived single‐scattering albedo spectra show blue slopes for both regions. Furthermore, the negative values of the asymmetry parameter, for both regions, indicate backscattering from the surface. The derived photometric parameters were used to normalize the observed reflectance and remove the photometric effects, resulting in significant improvement in the quality of the LAMP dayside maps.

AbstractSystemic vitamin E metabolites have been proposed as signaling molecules, but their physiological role is unknown. Here we show, by library screening of potential human vitamin E metabolites, that long-chain ω-carboxylates are potent allosteric inhibitors of 5-lipoxygenase, a key enzyme in the biosynthesis of chemoattractant and vasoactive leukotrienes. 13-((2R)-6-hydroxy-2,5,7,8-tetramethylchroman-2-yl)-2,6,10-trimethyltridecanoic acid (α-T-13′-COOH) can be synthesized from α-tocopherol in a human liver-on-chip, and is detected in human and mouse plasma at concentrations (8–49 nM) that inhibit 5-lipoxygenase in human leukocytes. α-T-13′-COOH accumulates in immune cells and inflamed murine exudates, selectively inhibits the biosynthesis of 5-lipoxygenase-derived lipid mediators in vitro and in vivo, and efficiently suppresses inflammation and bronchial hyper-reactivity in mouse models of peritonitis and asthma. Together, our data suggest that the immune regulatory and anti-inflammatory functions of α-tocopherol depend on its endogenous metabolite α-T-13′-COOH, potentially through inhibiting 5-lipoxygenase in immune cells.

AbstractX-chromosome inactivation (XCI) is an essential epigenetic process in female mammalian development. Although cell-based studies suggest the potential importance of the Ftx long non-protein-coding RNA (lncRNA) in XCI, its physiological roles in vivo remain unclear. Here we show that targeted deletion of X-linked mouse Ftx lncRNA causes eye abnormalities resembling human microphthalmia in a subset of females but rarely in males. This inheritance pattern cannot be explained by X-linked dominant or recessive inheritance, where males typically show a more severe phenotype than females. In Ftx-deficient mice, some X-linked genes remain active on the inactive X, suggesting that defects in random XCI in somatic cells cause a substantially female-specific phenotype. The expression level of Xist, a master regulator of XCI, is diminished in females homozygous or heterozygous for Ftx deficiency. We propose that loss-of-Ftx lncRNA abolishes gene silencing on the inactive X chromosome, leading to a female microphthalmia-like phenotype.

AbstractThe quest to develop an effective malaria vaccine remains a major priority in the fight against global infectious disease. An approach with great potential is a transmission-blocking vaccine which induces antibodies that prevent establishment of a productive infection in mosquitos that feed on infected humans, thereby stopping the transmission cycle. One of the most promising targets for such a vaccine is the gamete surface protein, Pfs48/45. Here we establish a system for production of full-length Pfs48/45 and use this to raise a panel of monoclonal antibodies. We map the binding regions of these antibodies on Pfs48/45 and correlate the location of their epitopes with their transmission-blocking activity. Finally, we present the structure of the C-terminal domain of Pfs48/45 bound to the most potent transmission-blocking antibody, and provide key molecular information for future structure-guided immunogen design.

AbstractRechargeable potassium-ion batteries have been gaining traction as not only promising low-cost alternatives to lithium-ion technology, but also as high-voltage energy storage systems. However, their development and sustainability are plagued by the lack of suitable electrode materials capable of allowing the reversible insertion of the large potassium ions. Here, exploration of the database for potassium-based materials has led us to discover potassium ion conducting layered honeycomb frameworks. They show the capability of reversible insertion of potassium ions at high voltages (~4 V for K2Ni2TeO6) in stable ionic liquids based on potassium bis(trifluorosulfonyl) imide, and exhibit remarkable ionic conductivities e.g. ~0.01 mS cm−1 at 298 K and ~40 mS cm–1 at 573 K for K2Mg2TeO6. In addition to enlisting fast potassium ion conductors that can be utilised as solid electrolytes, these layered honeycomb frameworks deliver the highest voltages amongst layered cathodes, becoming prime candidates for the advancement of high-energy density potassium-ion batteries.

AbstractThe observed trend towards warmer and drier conditions in southern Europe is projected to continue in the next decades, possibly leading to increased risk of large fires. However, an assessment of climate change impacts on fires at and above the 1.5 °C Paris target is still missing. Here, we estimate future summer burned area in Mediterranean Europe under 1.5, 2, and 3 °C global warming scenarios, accounting for possible modifications of climate-fire relationships under changed climatic conditions owing to productivity alterations. We found that such modifications could be beneficial, roughly halving the fire-intensifying signals. In any case, the burned area is robustly projected to increase. The higher the warming level is, the larger is the increase of burned area, ranging from ~40% to ~100% across the scenarios. Our results indicate that significant benefits would be obtained if warming were limited to well below 2 °C.

AbstractIt is generally assumed that cells interrogate the mechanical properties of their environment by pushing and pulling on the extracellular matrix (ECM). For instance, acto-myosin-dependent contraction forces exerted at focal adhesions (FAs) allow the cell to actively probe substrate elasticity. Here, we report that a subset of long-lived and flat clathrin-coated structures (CCSs), also termed plaques, are contractility-independent mechanosensitive signaling platforms. We observed that plaques assemble in response to increasing substrate rigidity and that this is independent of FAs, actin and myosin-II activity. We show that plaque assembly depends on αvβ5 integrin, and is a consequence of frustrated endocytosis whereby αvβ5 tightly engaged with the stiff substrate locally stalls CCS dynamics. We also report that plaques serve as platforms for receptor-dependent signaling and are required for increased Erk activation and cell proliferation on stiff environments. We conclude that CCSs are mechanotransduction structures that sense substrate rigidity independently of cell contractility.

AbstractResolving the microscopic pairing mechanism and its experimental identification in unconventional superconductors is among the most vexing problems of contemporary condensed matter physics. We show that Raman spectroscopy provides an avenue towards this aim by probing the structure of the pairing interaction at play in an unconventional superconductor. As we study the spectra of the prototypical Fe-based superconductor Ba1−xKxFe2As2 for 0.22 ≤ x ≤ 0.70 in all symmetry channels, Raman spectroscopy allows us to distill the leading s-wave state. In addition, the spectra collected in the B1g symmetry channel reveal the existence of two collective modes which are indicative of the presence of two competing, yet sub-dominant, pairing tendencies of $$d_{x^2 - y^2}$$

symmetry type. A comprehensive functional Renormalization Group and random-phase approximation study on this compound confirms the presence of the two sub-leading channels, and consistently matches the experimental doping dependence of the related modes. The consistency between the experimental observations and the theoretical modeling suggests that spin fluctuations play a significant role in superconducting pairing.
Effect on Local Structure and Phase Transition of Perovskite-Type [N(CH3)4]2Zn1-xCuxBr4 (x = 0, 0.5, 0.7, and 1) Crystals with the Various Doping of Cu2+ Ions
Authors: Lim Ae Ran 
Published: September 2018

AbstractThis study focused on how the local structures in pure [N(CH3)4]2ZnBr4 crystal are affected by the partial replacement of Zn2+ ions with Cu2+ ions. The structures and phase transition temperatures TC of perovskite-type [N(CH3)4]2Zn1-xCuxBr4 (x = 0, 0.5, 0.7, and 1) mixed crystals were almost unchanged by the partial doping of Cu2+ ions. The environments for the local structures of [N(CH3)4]2Zn1-xCuxBr4 mixed systems were studied according to differences in the chemical shifts of the 1H magic angle spinning (MAS) NMR, 13C cross-polarization (CP)/MAS NMR, and 14N NMR spectra. The 1H and 13C NMR results showed that the local environments of 1H and 13C nuclei near TC are not affected by substituting Zn2+ ions with Cu2+ ions, whereas the 14N NMR results showed that the local environment is affected near TC. Consequently, the main indicators of the phase transition in [N(CH3)4]2Zn1-xCuxBr4 are related to the ferroelastic characteristics with different orientations.

Published: September 2018

AbstractIn this study, we proposed an approach to recommend environmental flows in highly regulated areas, considering the multiple time scales of hydrological processes and water requirements. Water resources were seasonally allocated to the agricultural sector using a benefit-maximizing model, based on water deficiency at different crop growth stages. The economic feedback was evaluated after securing different levels of initial environmental flows. The final environmental flows were recommended to maintain a balance between the ecosystem and irrigation water needs. A case study was applied in the Baiyangdian watershed, China. The results show that a benefit-maximizing model can reduce the total economic losses to the maximum potential, which contributes to alleviating water use conflicts between agriculture and the ecosystem. However, the environmental flows cannot be maintained without the sacrifice of production losses, except for in extremely wet years. Average environmental flows could be secured at around 3.1, 4.3 and 5.4 × 108m3in dry, average, and wet years, respectively, with less than 10% production loss. Additional water transfer projects, as well as economic compensation strategies, are suggested to meet both ecosystem and agricultural needs. The planned economic compensation during 2010–2015 was 16.3 × 108Yuan, giving priority to securing environmental flows, and accounting for 7% of the total agricultural output value. The suggested amount of water resource transferred by the South-to-North Transfer Projects was 19 × 108m3, which is enough to alleviate water use conflicts between different stakeholders in dry years. This study provided a method to protect ecosystems in a more sustainable way.
