In 1995 a strain of Ectocarpus was isolated from Hopkins River Falls, Victoria, Australia, constituting one of few available freshwater or nearly freshwater brown algae, and the only one belonging to the genus Ectocarpus. It has since been used as a model to study acclimation and adaptation to low salinities and the role of its microbiota in these processes. To provide more background information on this model, we assessed if Ectocarpus was still present in the Hopkins river 22 years after the original finding, estimated its present distribution, described its abiotic environment, and determined its in situ microbial composition. We sampled for Ectocarpus at 15 sites along the Hopkins River as well as 10 neighboring sites and found individuals with ITS and cox1 sequences identical to the original isolate at three sites upstream of Hopkins River Falls. The salinity of the water at these sites ranged from 3.1 to 6.9, and it was rich in sulfate (1–5 mM). The diversity of bacteria associated with the algae in situ (1312 operational taxonomic units) was one order of magnitude higher than in previous studies of the original laboratory culture, and 95 alga‐associated bacterial strains were isolated from algal filaments on site. In particular, species of Planctomycetes were abundant in situ but rare in laboratory cultures. Our results confirmed that Ectocarpus was still present in the Hopkins River, and the newly isolated algal and bacterial strains offer new possibilities to study the adaptation of Ectocarpus to low salinity and its interactions with its microbiome.
Thermal and porosity properties of meteorites: A compilation of published data and new measurements

Published: January 2020

AbstractWe report direct measurements of thermal diffusivity and conductivity at room temperature for 38 meteorite samples of 36 different meteorites including mostly chondrites, and thus almost triple the number of meteorites for which thermal conductivity is directly measured. Additionally, we measured porosity for 34 of these samples. Thermal properties were measured using an optical infrared scanning method on samples of cm‐sizes with a flat, sawn surface. A database compiled from our measurements and literature data suggests that thermal diffusivities and conductivities at room temperature vary largely among samples even of the same petrologic and chemical type and overlap among, for example, different ordinary chondrite classes. Measured conductivities of ordinary chondrites vary from 0.4 to 5.1 W m−1 K−1. On average, enstatite chondrites show much higher values (2.33–5.51 W m−1 K−1) and carbonaceous chondrites lower values (0.5–2.55 W m−1 K−1). Mineral composition (silicates versus iron‐nickel) and porosity control conductivity. Porosity shows (linear) negative correlation with conductivity. Variable conductivity is attributed to heterogeneity in mineral composition and porosity by intra‐ and intergranular voids and cracks, which are important in the scale of typical meteorite samples. The effect of porosity may be even more significant for thermal properties than that of the metal content in chondrites.

AbstractThis paper aimed to examine the effect of breastfeeding on longitudinal patterns of common infections up to 2 years and respiratory symptoms up to 8 years. To assess the incidence and reoccurrence of infections and allergic symptoms in the first years of life among 1,603 children from the EDEN mother–child cohort, distinct longitudinal patterns of infectious diseases as well as skin rash and respiratory symptoms were identified by group‐based trajectory modelling. To characterize infections, we considered the parent‐reported number of cold/nasopharyngitis and diarrhoea from birth to 12 months and otitis and bronchitis/bronchiolitis from birth to 2 years. To characterize allergy‐related symptoms, we considered the parent‐reported occurrence of wheezing and skin rash from 8 months to 8 years and asthma from 2 to 8 years. Then associations between breastfeeding and these longitudinal patterns were assessed through adjusted multinomial logistic regression. Compared with never‐breastfed infants, ever‐breastfed infants were at a lower risk of diarrhoea events in early infancy as well as infrequent events of bronchitis/bronchiolitis throughout infancy. Only predominant breastfeeding duration was related to frequent events of bronchitis/bronchiolitis and infrequent events of otitis. We found no significant protective effect of breastfeeding on longitudinal patterns of cold/nasopharyngitis, skin rash, or respiratory symptoms. For an infant population with a short breastfeeding duration, on average, our study confirmed a protective effect of breastfeeding on diarrhoea events in early infancy, infrequent bronchitis/bronchiolitis and, to a lesser extent, infrequent otitis events up to 2 years but not on other infections, skin rash, or respiratory symptoms4.
Applicability of machine learning to a crack model in concrete bridges

Published: January 2020

AbstractThe growing demand for a more efficient maintenance of concrete bridges requires a model that tracks the deterioration of each bridge based on inspection data. Although it has been expected that machine learning could be applied to this problem, inspection data sparsely distributed over time are not suitable for machine learning in contrast to the continuous big data usually targeted. This study applies machine learning to a regression model of crack formation and propagation using inspection data to confirm the applicability. It includes the selection of the optimal algorithm, development of the model based on a novel methodology, and factor analysis using the model. Accordingly, the model was constructed by Gaussian process regression and it could appropriately extract the differences in the progress of crack damage due to multiple influential factors. The results demonstrate the excellent applicability of machine learning even to sparse data.
Nitric oxide as a developmental and metabolic signal in filamentous fungi

Published: January 2020

AbstractThe short‐lived hydrophobic gas nitric oxide (NO) is a broadly conserved signaling molecule in all domains of life, including the ubiquitous and versatile filamentous fungi (molds). Several studies have suggested that NO plays a vast and diverse signaling role in molds. In this review, we summarize NO‐mediated signaling and the biosynthesis and degradation of NO in molds, and highlight the recent advances in understanding the NO‐mediated regulation of morphological and physiological processes throughout the fungal life cycle. In particular, we describe the role of NO in molds as a signaling molecule that modulates asexual and sexual development, the formation of infection body appressorium, and the production of secondary metabolites (SMs). In addition, we also summarize NO detoxification and protective mechanisms against nitrooxidative stress.
Radical Orthodoxy on Catholicism, Protestantism and Liberalism/Liberality: On the Use of Historical Narratives and Quantitative Methods in Political Theology
Authors: Rasmusson Arne 
Published: January 2020

AbstractPolitical theology assumes or depends, implicitly or explicitly, on historical narratives and empirical claims. For theologians making historical, socio‐cultural and economic claims an interdisciplinary use of several different methods is helpful, including a theologically and philosophically informed combination of historical narratives with social and economic quantitative methods. This argument is fleshed out by a critical analysis of historical and sociological claims about Catholicism, Anglicanism, and Protestantism in relation to liberalism and liberality, which are central to the argument of John Milbank’s and Adrian Pabst’s book The Politics of Virtue. They find the roots of an increasingly untenable abstract atomistic liberalism both in late medieval and Protestant (especially Calvinist) theology as well as in the dissenting nonconforming traditions that worked for the disestablishment of the Church. This very disestablishment is part of what creates modern liberalism. This article both sketches a partly alternative history to the one Milbank and Pabst provide, pointing to the role of creative minorities in certain dissenting Protestant churches and movements for the emergence of the type of liberality Milbank and Pabst defend, and tests these claims against quantitative social science studies on democracy, social trust, and corruption.
A puzzle about the experience of left and right
Authors: Cutter Brian 
Published: January 2020

AbstractImagine your mirror‐inverted counterpart on Mirror Earth, a perfect mirror image of Earth. Would her experiences be the same as yours, or would they be phenomenally mirror‐inverted? I argue, first, that her experiences would be phenomenally the same as yours. I then show that this conclusion gives rise to a puzzle, one that I believe pushes us toward some surprising and philosophically significant conclusions about the nature of perception. When you have a typical visual experience as of something to your left, the following three claims seem very plausible: (1) No one could have an experience phenomenally just like yours without thereby having an experience as of something to her left. (2) Your experience is veridical. (3) Your experience doesn't differ from that of your mirror‐inverted counterpart with respect to veridicality. But (1)‐(3) jointly contradict the claim that you and your mirror‐inverted counterpart would have the same experiences. I argue that any viable response to this puzzle will embrace the following disjunction: either there is a degree of independence between perceptual phenomenology and representational content, contrary to popular intentionalist views of perception, or spatial subjectivism is true, where spatial subjectivism is the view that the spatial properties presented in perception are either mind‐dependent or illusory.

AbstractThe Shinyemi and Gagok deposits, located in the Taebaeksan Basin, South Korea, display Zn–Pb mineralization along a contact between Cretaceous granitoids and Cambrian–Ordovician carbonates of the Joseon Supergroup. The Shinyemi mine is one of the largest polymetallic skarn‐type magnetite deposits in South Korea and comprises Fe and Fe–Mo–Zn skarns, and Zn–Cu–Pb replacement deposits. Both deposits yield similar Cretaceous mineralization ages, and granitoids associated with the two deposits displaying similar mineral textures and compositions, are highly evolved, and were emplaced at a shallow depth. They are classified as calc‐alkaline, I‐type granites (magnetite series) and were formed in a volcanic arc. Compositional variation is less in the Shinyemi granites and aplites (e.g., SiO2 = 74.4–76.6 wt% and 74.4–75.1 wt%, respectively) than in the Gagok granites and aplites (e.g., SiO2 = 65.6–68.0 wt% and 74.9–76.5 wt%, respectively). Furthermore, SiO2 vs K/Rb and SiO2 vs Rb/Sr diagrams indicate that the Shinyemi granitoids are more evolved than the Gagok granitoids. Shinyemi granitoids had been already differentiated highly in deep depth and then intruded into shallow depth, so both granite and aplite show the highly evolved similar chemical compositions. Whereas, less differentiated Gagok granitoids were separated into two phases in the last stage at shallow depth, so granite and aplite show different compositions. The amounts of granites and aplite are similar in the Shinyemi deposit, whereas the aplite appears in an amount less than the granite in the Gagok deposit. For this reason, the Shinyemi granitoids caused not only Fe enrichment during formation of the dolomite‐hosted magnesian skarn but also was associated with Mo mineralization in the Shinyemi deposit. Zn mineralization of the Gagok deposit was mainly caused by granite rather than aplite. Our data suggest that the variation in mineralization displayed by the two deposits resulted from differences in the compositions of their associated igneous intrusions.
Mobile money, risk sharing, and educational investment: Panel evidence from rural Uganda
Authors: Tabetando Rayner , Matsumoto Tomoya 
Published: January 2020

AbstractWe examine the impact of the rapidly expanding mobile banking service “mobile money” on rural households' ability to smooth investment in schooling after a negative shock. We find that a negative shock induces a 9.3‐percentage point decrease in per school‐age child educational expenditure for households who do not use mobile money compared to an 8.3‐percentage point decrease for households that have adopted mobile money. The underlying mechanism is an increase in remittance receipt and the diversity of senders owing to the reduction in transactions cost provided by mobile money. We show that our results are robust to alternative mechanisms. We use the expansion in mobile money agent network as an exogenous variation in access to mobile money.
Elections and Policy Responsiveness: Evidence from Environmental Voting in the U.S. Congress
Authors: McAlexander Richard J. , Urpelainen Johannes 
Published: January 2020

AbstractDo elections affect legislators' voting patterns? We investigate this question in the context of environmental policy in the U.S. Congress. We theorize that since the general public is generally in favor of legislation protecting the environment, legislators have an incentive to favor the public over industry and vote for pro‐environment legislation at election time. The argument is supported by analyses of data on environmental roll call votes for the U.S. Congress from 1970 to 2013 where we estimate the likelihood of casting a pro‐environment vote as a function of the time to an election. While Democrats are generally more likely to cast a pro‐environment vote before an election, this effect is much stronger for Republicans when the legislator won the previous election by a thinner margin. The election effect is maximized for candidates receiving substantial campaign contributions from the (anti‐environment) oil and gas industry. Analysis of Twitter data confirms that Congressmembers make pro‐environmental statements and highlight their roll call voting behavior during the election season. These results show that legislators do strategically adjust their voting behavior to favor the public immediate prior to an election.
Going beyond a positive–negative dichotomy in judgment and decision‐making research: Insights for framing, counterfactual thinking, and ambivalence
Authors: Sparks Jehan 
Published: January 2020

AbstractMany areas of judgment and decision‐making research have historically relied on a simple positive–negative dichotomy (e.g., positive vs. negative framing). Although this classic assumption about the conceptual space has contributed to some of the field's more impactful findings (e.g., framing effects), it may also have mistakenly led us to believe that these findings told a complete story about biases in processing positive and negative information. Building on a tradition of theoretical accounts outlining how positive and negative information is more complex, the first part of this paper considers how the following three elements jointly help to tell a more complete story about framing effects: (a) regulatory focus theory's concept of the domain (loss vs. gain) of an outcome, (b) the sequencing of positive and negative frames, and (c) the asymmetric influences of positive and negative evaluative processes. Next, the paper reviews research that has contributed to integrating these elements, highlighting opportunities for further integration to generate new insights for framing effects, risky decision‐making, counterfactual thinking, and ambivalence. The reviewed studies suggest that a more sophisticated conceptualization of positive and negative information contributes to a deeper understanding of the basic processes that govern human judgment and decision‐making.
Optimization of the Design of Hydrogen Production Systems Based on Product Cost
Authors: Mraoui Abdelhamid , Khellaf Abdallah 
Published: January 2020

Abstract
In this work, the design of a hydrogen production system was optimized for Algiers in Algeria. The system produces hydrogen by electrolysis using a photovoltaic (PV) generator as a source of electricity. All the elements of the system have been modeled to take into account practical constraints. The cost of producing hydrogen has been minimized by varying the total power of the photovoltaic generator. An optimal ratio between the peak power of the PV array and the nominal power of the electrolyzer was determined. Photovoltaic module technology has been varied using a large database of electrical characteristics. It was noted that PV technology does not have a very significant impact on cost. The minimum cost is around 0.44$/N m3, and the power ratio in this case is 1.45. This results in a cost reduction of around 12% compared to a unit ratio. The power ratio and cost are linearly dependent. Only a small number of technologies give a relatively low cost of about 0.35$/N m3. These generators are interesting; however, we assumed an initial cost of $2.00/Wp for all technologies. In addition, it was noted that it is possible to increase hydrogen production by 10% by increasing the power of the photovoltaic generator, the extra cost in this case will only be 0.1%.

Published: January 2020

Abstract
Thermal transport and flow friction characteristics due to roughness on the absorber plate of solar air heater are evaluated by applying three-dimensional finite volume based code. Renormalization group (RNG) k–ɛ model is employed to capture the turbulent nature of the flow. The effect of equilateral prism-shaped rib roughness geometrical parameters in terms of relative roughness height (e/D) and relative roughness pitch (p/e) on heat transfer and flow friction is analyzed. Further, the effect of flow parameter, Re in the range of 4000–18,000 is also explored. Results are elucidated in terms of average Nusselt number, friction factor, turbulent kinetic energy, and eddy dissipation. Results are compared with a smooth absorber plate solar air heater. Thermo-hydraulic performance of the roughened solar air heater is analyzed. Noteworthy augmentation in heat transport is obtained. The thermal enhancement factor is calculated for optimal performance and found to vary from 1.7 to 3.5. However, friction factor and pressure loss for roughened plate is significantly higher than its smooth counterpart. The pressure drop across the test section increases with the rise in roughness height due to flow obstruction. A minimum value of the friction factor enhancement ratio worth 2.13 is obtained. Enhancement in thermal transport and pressure losses are combined by introducing a thermo-hydraulic performance factor (THHP). For the range of parameters investigated, the optimum value of the thermo-hydraulic performance factor is found to be 3.41. Correlations for average Nusselt number and friction factor are offered at the end.

Published: January 2020

AbstractAdvancement of human civilization has led to rapid industrialization going in hand with urbanization and globalization, which have elevated energy demand worldwide. Conventional energy sources with the fear of being exhausted at a rapid pace seem to fail to quench inflated energy demand alone. Solar being a ubiquitous and eco-friendly source of renewable energy has become one of the most dominant forms of power generation implemented in diverse applications. To maximize the efficacy of the solar photovoltaic (SPV) system, it must be operated at maximum power point (MPP) that incorporates the use of maximum power point tracking (MPPT) algorithm. MPPT algorithm is a self-automated control technique that compels the SPV system to operate at MPP thereby harnessing maximum obtainable power under time-varying environmental conditions such as solar intensity, temperature, SPV module characteristics, and module shading. This paper puts forward an elaborated study on 27 MPPT techniques that are pervasive in the SPV system. The entire assessment deals with MPPT techniques employed under uniform solar insolation varying from time to time as well as global maximum power point tracking (GMMPT) techniques employed under partial shading (PS) conditions. Vivid comparisons among all the MPPT techniques along with their brief discussion, merits, and demerits have been done. Moreover, a detailed structure of error-based incremental conductance MPPT has been proposed.
Lotus-Leaf Inspired Surfaces: Hydrophobicity Evolution of Replicas Due to Mechanical Cleaning and Mold Wear

Published: January 2020

AbstractInspired from the low wetting properties of Lotus leaves, the fabrication of dual micro/nanoscale topographies is of interest to many applications. In this research, superhydrophobic surfaces are fabricated by a process chain combining ultrashort pulsed laser texturing of steel inserts and injection molding to produce textured polypropylene (PP) parts. This manufacturing route is very promising and could be economically viable for mass production of polymeric parts with superhydrophobic properties. However, surface damages, such as wear and abrasion phenomena, can be detrimental to the attractive wetting properties of replicated textured surfaces. Therefore, the final product lifespan is investigated using mechanical cleaning of textured PP surfaces with multipurpose cloths following the ASTM D3450 standard. Second, the surface damage of replication masters after 350 injection molding cycles with glass-fiber-reinforced PP, especially to intensify mold wear, was investigated. In both cases, the degradation of the dual-scale surface textures had a clear impact on surface topography of the replicas and thus on their wetting properties, too.
