The Ecocritical Implications of Downing's Influence on Poe's Landscape Aesthetic
Authors: Bayer Ellen M. 
Published: November 2018

Abstract
This article examines the influence of landscape architect Andrew Jackson Downing's seminal work, A Treatise on the Theory and Practice of Landscape Gardening (1841), on Poe's landscape tales. Poe knew this book through reading a review in Arcturus appearing in the same year and, as strong evidence suggests, through perusing Downing's tract firsthand sometime before 1843. Looking at the affinities between Downing's and Poe's aesthetic principles, we may see that Downing's landscape gardening theory profoundly influenced Poe's later fiction and validated his belief in the powerful role of the artist in the creation of Beauty. Two landscape tales, in particular, demonstrate the correlation between Poe's writing and the principles of landscape gardening popularized in his time: “The Domain of Arnheim” of 1847, and its “pendant,” “Landor's Cottage” of 1849. Situating Poe's work in the context of landscape gardening—first by establishing Downing's influence on Poe and then by examining the environmental impact of their idealized landscapes—we may see how both literary and horticultural texts echoed the broader culture's demand for a composed American landscape without considering the environmental consequences of putting these aesthetic theories into practice.
Rising declaratives of the Quality-suspending kind
Authors: Westera Matthijs 
Published: November 2018

The theory of Intonational Compliance Marking (ICM) maintains that speakers of English use final rising intonation to indicate a suspension (potential violation) of a conversational maxim (Westera 2013; 2014). This paper aims to show that a certain kind of rising declarative, one which has been prominent in the literature (e.g., Gunlogson 2008), can be adequately understood in ICM’s terms as involving a suspension of the maxim of Quality. By explicating certain minimal assumptions about pragmatics, this understanding accounts for three core features of such rising declaratives: their question-likeness, the speaker bias they express and their badness out of the blue. In a nutshell, their question-likeness is derived from principles of general cooperative discourse, their bias from the relative importance of the maxim of Quality, and their badness out of the blue from a competition between rising declaratives and interrogatives. The account is compared in detail to various existing accounts of rising declaratives of the relevant sort, highlighting explanatory and empirical differences.
A fast Iris recognition system through optimum feature extraction

Published: November 2018

With an increasing demand for stringent security systems, automated identification of individuals based on biometric methods has been a major focus of research and development over the last decade. Biometric recognition analyses unique physiological traits or behavioral characteristics, such as an iris, face, retina, voice, fingerprint, hand geometry, keystrokes or gait. The iris has a complex and unique structure that remains stable over a person's lifetime, features that have led to its increasing interest in its use for biometric recognition.
In this study, we proposed a technique incorporating Principal Component Analysis (PCA) based on Discrete Wavelet Transformation (DWT) for the extraction of the optimum features of an iris and reducing the runtime needed for iris templates classification. The idea of using DWT behind PCA is to reduce the resolution of the iris template. DWT converts an iris image into four frequency sub-bands. One frequency sub-band instead of four has been used for further feature extraction by using PCA. Our experimental evaluation demonstrates the efficient performance of the proposed technique.
Numbers that tell a story: Measuring the impact of open access books

Open access book publishing is gaining momentum, with more than 10,000 titles published worldwide. But compared to the overall number of academic books that are produced, this is still a small percentage. With much research on the benefits to society from open access publication, what can we do to encourage more book authors to choose open access?Springer Nature is a leading academic book publisher – to date, we have published more than 550 open access books since launching OA book options in 2012. Feedback from our OA book authors has shown that metrics are important to them, as the data helps demonstrate the impact of their research to funders, and also supports conversations with their institutions for career progression. However, as highlighted in our white paper ‘The OA effect: How does open access affect the usage of scholarly books?’, some authors feel that there is a lack of information around metrics and book performance. This information may be critically important in helping authors consider the benefits of choosing to publish their book open access.Authors also state that one of the main obstacles to publishing more OA books through the gold route is funding; access to which varies globally and by discipline – a central theme that emerged at our researcher event during Academic Book Week 2018.Meanwhile, funders interviewed for ‘The OA Effect’ told us that they were keen to understand the impact of the OA books they had supported, but few had actually done so; many commented on the difficulties of measuring the impact of research. In light of these findings, in 2018 we piloted a new “impact report”, based on metrics for an individual funder of OA books. The outcomes of this pilot impact report project will help the scholarly communications community to better understand how publishers can inform funders, authors and their institutions about the impact of their research, and on a wider scale. What are the challenges of sharing the benefits of OA book publishing with researchers across different disciplines, and how can we overcome these challenges?Our poster shows excerpts from the pilot impact report, quotes from authors and funders about research impact, and considers next steps.

An Information‐Theoretic Approach for the Evaluation of Surrogate Endpoints
Authors: Abad Ariel A. 
Published: November 2018

AbstractA unifying information‐theoretic approach for the evaluation of surrogate endpoints is discussed. This methodological framework offers an intuitive yet rigorous definition of surrogacy and provides a general metric that can be applied across different scenarios to quantify the validity of a surrogate, within both the meta‐analytic and causal‐inference paradigms.
Effect of Chemical Bonding Characteristics on Ordering Structure in Li Spinel Oxides
Authors: Ryoo Hyewon , Lee Sang‐Gil , Kim Jin‐Gyu , Chung Sung‐Yoon 
Published: November 2018

AbstractAn ordered configuration between atoms is frequently observed in many alloys and complex ionic compounds, as the ordering structure is energetically more stable in terms of the lattice enthalpy. However, when the entropy effect becomes dominant with increasing temperature, the ordered configurational symmetry is subject to be thermally perturbed, resulting in a transition to a random distribution of atoms at elevated temperature. By comparing two Li(B′B″)2O4‐type spinel oxides having an identical space group and analogous compositions, it can be elucidated that the locally distinct chemical bonding characteristics, which are substantially covalent versus highly ionic, make a significant contribution to the formation of ordering. More importantly, such ordering structure is considerably robust without perturbation even at very high temperature near the melting point. The findings in this work suggest that the locally different bonding nature is one of the critical structure‐determining factors in complex oxides with multiple cations, emphasizing the significance of in‐depth understanding of the correlation of electronic configurations with the overall crystalline structure.

Published: November 2018

AbstractPeptide‐drug conjugates (PDCs) are a type of self‐assembled prodrug with good potential for drug delivery due to their excellent biocompatibility, high drug loading, and permanent controllable release. However, most PDCs tend to self‐assemble into filamentous nanostructures in water and under physiological conditions, making them unsuitable as intravenous formulations due to the entanglement of long fibers and the risk of thrombus. Injected PDCs also face challenges in overcoming the complex physiological environment to reach the target site. To expand their clinical use, it is necessary to control the properties of PDC, including the self‐assembled structure and physiological performance, to avoid the above problems. Based on assembly mechanism studies of PDCs, a new method for regulating PDC morphology is developed by controlling intermolecular interactions in the assembly process. This method can alter the final morphology of PDCs from nanofibers to nanorods, and the introduced macromolecules endow the PDC with new characteristics that facilitate stable and high‐efficiency access to the target site.

AbstractAu nanorods (NRs) decorated carbon nitride nanotubes (Au NRs/CNNTs) photocatalysts have been designed and prepared by impregnation–annealing approach. Localized surface plasmon resonance (LSPR) peaks of Au NRs can be adjusted by changing the aspect ratios, and the light absorption range of Au NRs/CNNTs is extended to longer wavelength even near‐infrared light. Optimal composition of Pt@Au NR769/CNNT650 has been achieved by adjusting the LSPR peaks of Au NRs and further depositing Pt nanoparticles (NPs), and the photocatalytic H2 evolution rate is 207.0 µmol h−1 (20 mg catalyst). Preliminary LSPR enhancement photocatalytic mechanism is suggested. On one hand, LSPR of Au NRs is beneficial for visible‐light utilization. On the other hand, Pt NPs and Au NRs have a synergetic enhancement effect on photocatalytic H2 evolution of CNNTs, in which the local electromagnetic field can improve the photogenerated carrier separation and direct electron transfer increases the hot electron concentration while Au NRs as the electron channel can well restrain charge recombination, finally Pt as co‐catalyst can boost H+ reduction rate. This work provides a new way to develop efficient photocatalysts for splitting water, which can simultaneously extend light absorption range and facilitate carrier generation, transportation and reduce carrier recombination.

AbstractAs a prerequisite elementary step, carburization of iron oxides to form iron carbides is critically important to display activity for iron‐based Fischer–Tropsch synthesis catalysts. The positive role of the Cu promoter to advocate the reduction of the iron oxides has long been known. Nevertheless, its complex influence along the carburization of catalyst precursors remains controversial. Here, we resolve this decades‐long question by using a state‐of‐the‐art in situ X‐ray diffraction (XRD) method to elucidate the multi‐role of Cu promoter in modulation of carburization rate, composition of post‐carburization samples, and morphology evolution of prepared iron carbide particles under CO/He (v/v=2 %/98 %) and H2/CO/He (v/v/v=8 %/2 %/90 %) gaseous environment, by excluding the possible interference from promoter components other than Cu. We anticipate that this study enriches current tool box in the research of a specific promoter of the Fischer‐Tropsch synthesis catalysts.

Published: November 2018

ABSTRACTA one‐step aldol condensation reaction of methyl propionate and formaldehyde to produce methyl methacrylate is a promising environmentally sustainable strategy. In this work, the aldol condensation reaction was firstly conducted in a fluidized bed reactor using different types of catalysts. Zirconium and cesium‐loaded SiO2 and Al2O3 acid‐base bifunctional catalysts were prepared by wetness impregnation. Experimental results demonstrated the 15 % Cs‐0.05 %Zr/SiO2 (100–200 mesh) catalyst exhibited excellent catalytic performance. The effects of the supports, reaction temperature, carrier gas flow rate, and feed rate were investigated and optimized. When the flow rate of carrier gas (N2) was 280 cm3/min and the feed rate was 0.6 cm3/min, the methyl propionate conversion was 25.2 % and the methyl methacrylate selectivity could reach 86.1 %. Although the catalytic activity of the 15 %Cs‐0.05 %Zr/SiO2 catalyst dropped with reaction time on stream due to carbon deposition on the surface of catalyst, its activity was restored by a simple regeneration method.

Published: November 2018

AbstractThe solid‐form screening of active principal ingredients is a challenge for pharmaceutical drug development, as more than 80 % of marketed drugs are formulated in the solid form. A broad and comprehensive study of the various solid forms of drugs is needed to enhance their translation into the clinic. Therefore, the most suitable solid form must be taken into consideration regarding ex vivo and in vivo stability, targeting, solubility, dissolution rate, and bioavailability. In this review, techniques of solid‐form screening are covered, including differences in solid forms such as polymorphs, solvates, salts, co‐crystals, and amorphous particles. Moreover, solid drug size reduction is also discussed, with insight into the emergence of drug nanocrystal formulations. An overview of the smallest nanocrystals reported in the literature and on the market is also provided, along with their applications and routes of administration.

AbstractIntroductionThere is an emerging need for telecytology in Colombia as the demand for cytopathology has increased. However, due to economic and technological constraints telecytology services are limited. Our aim was to evaluate the diagnostic feasibility of using whole slide imaging with and without Z‐stacking for telecytology in Colombia, South America.MethodsArchival glass slides from 17 fine needle aspiration smears were digitized employing whole slide imaging (WSI) (Nanozoomer 2.0 HT, Hamamatsu) in one Z‐plane at 40x, and panoramic digital imaging (Panoptiq system, ViewsIQ) combining low‐magnification digital maps with embedded 40x Z‐stacks of representative regions of interest. Fourteen Colombian pathologists reviewed both sets of digital images. Diagnostic concordance, time to diagnosis, image quality (scale 1–10), usefulness of Z‐stacking, and technical difficulties were recorded.ResultsImage quality scored by pathologists was on average 8.3 for WSI and 8.7 for panoramic images with Z‐stacks (P = .03). However, diagnostic concordance was not impacted by image quality ranking. In the majority of cases (72.4%) pathologists deemed Z‐stacking to be diagnostically helpful. Technical issues related to Z‐stack video performance constituted only a minor proportion of technical problems reported. Slow downloads and crashing of files while viewing were mostly experienced with larger WSI files.ConclusionThis study demonstrated that international telecytology for diagnostic purposes is feasible. Panoramic images had to be acquired manually, but were of suitable diagnostic quality and generated smaller image files associated with fewer technical errors. Z‐stacking proved to be useful in the majority of cases and is thus recommended for telecytology.

AbstractGrowth patterns of aquatic macrophytes have been shown to vary in response to hydrological properties; however, such properties are typically characterized by water level fluctuation, flow velocity, flooding season, and sedimentation, but not by water exchange rate (WER). Herein, we experimentally investigated how WER (three levels: exchange 0%, 20%, and 40% of total water per day) affects water and sediment properties, and the consequences that these variations have on the individual responses of two submerged macrophytes, Hydrilla verticillata and Myriophyllum aquaticum which were planted in two different sediment types (sand and clay). In the experiment without ramets, it was found that turbidity, pH value, and dissolved carbon dioxide concentration of the system water were statistically unaffected by WER, while water dissolved oxygen (DO) concentration and sediment oxidation–reduction potential (ORP, in both sediments) consistently increased with increasing WER, regardless of experimental time. In the experiment containing ramets, biomass accumulation and relative growth rate (RGR) of both species gradually increased with increasing WER regardless of sediment type. The mechanisms were related to (a) increased oxygen availability, as indicated by gradually increased water DO concentration and sediment ORP; and (b) enhanced phosphorus (P) and nitrogen (N) absorbing abilities associated with stimulated root growth, reflected in increased mean root length, specific root length, and the root/above‐ground biomass ratio, with increasing WER. Additionally, in the experiments containing ramets, significant linear relationships were consistently detected between sediment ORP and root parameters, root parameters and plant nutrients (N and P), and plant nutrients and plant growth conditions (biomass accumulation and RGR). These results demonstrate that WER plays an important role in determining oxygen availability and thus impacts the growth of submerged macrophytes by altering the ability of roots to absorb nutrients, indicating that ecosystem functions are more sensitive to WER than previously recognized.

Published: November 2018

AbstractReliable species identification is vital for survey and monitoring programs. Recently, the development of digital technology for recording and analyzing vocalizations has assisted in acoustic surveying for cryptic, rare, or elusive species. However, the quantitative tools that exist for species differentiation are still being refined. Using vocalizations recorded in the course of ecological studies of a King Rail (Rallus elegans) and a Clapper Rail (Rallus crepitans) population, we assessed the accuracy and effectiveness of three parametric (logistic regression, discriminant function analysis, quadratic discriminant function analysis) and six nonparametric (support vector machine, CART, Random Forest, k‐nearest neighbor, weighted k‐nearest neighbor, and neural networks) statistical classification methods for differentiating these species by their kek mating call. We identified 480 kek notes of each species and quantitatively characterized them with five standardized acoustic parameters. Overall, nonparametric classification methods outperformed parametric classification methods for species differentiation (nonparametric tools were between 57% and 81% accurate, parametric tools were between 57% and 60% accurate). Of the nine classification methods, Random Forest was the most accurate and precise, resulting in 81.1% correct classification of kek notes to species. This suggests that the mating calls of these sister species are likely difficult for human observers to tell apart. However, it also implies that appropriate statistical tools may allow reasonable species‐level classification accuracy of recorded calls and provide an alternative to species classification where other capture‐ or genotype‐based survey techniques are not possible.
