Phase-field approximation for a class of cohesive fracture energies with an activation threshold
Authors: Chambolle Antonin , Crismale Vito 
Published: January 2020

AbstractWe study the Γ-limit of Ambrosio–Tortorelli-type functionalsDε⁢(u,v){D_{\varepsilon}(u,v)}, whose dependence on the symmetrised gradiente⁢(u){e(u)}is different in𝔸⁢u{\mathbb{A}u}and ine⁢(u)-𝔸⁢u{e(u)-\mathbb{A}u}, for aℂ{\mathbb{C}}-elliptic symmetric operator𝔸{\mathbb{A}}, in terms of the prefactor depending on the phase-field variablev. The limit energy depends both on the opening and on the surface of the crack, and is intermediate between the Griffith brittle fracture energy and the one considered by Focardi and Iurlano [Asymptotic analysis of Ambrosio–Tortorelli energies in linearized elasticity, SIAM J. Math. Anal. 46 2014, 4, 2936–2955]. In particular, we prove that G(S)BD functions with bounded𝔸{\mathbb{A}}-variation are (S)BD.
Non-Financial Reporting & Corporate Governance: Explaining American Divergence & Its Implications for Disclosure Reform
Authors: Harper Ho Virginia 
Published: January 2020

Abstract
Non-financial reporting reforms have moved ahead around the world as governments work to advance sustainable development and improve environmental, social, and governance (“ESG”) risk management by firms and investors In the United States, however, non-financial reporting reforms face resistance and have lagged behind. This article offers an overview of the state of non-financial reporting in the U.S. and explains why the U.S. approach still diverges so visibly from the reform path adopted by other governments around the world. It then suggests potential directions for non-financial disclosure reform that take account of the U.S. institutional context. The article concludes by considering the implications of the United States’ market-driven approach for non-financial reporting reform and for the future of sustainable finance more broadly.

For such an operator we define the area integral$\begin{array}{} \displaystyle S^{L}_h \end{array}$associated with the heat semigroup and obtain the area integral characterization of$\begin{array}{} \displaystyle H^{1}_{L} \end{array}$, which is the Hardy space associated withL.
Thermal Response in Cellulose Iβ Based on Molecular Dynamics
Authors: Jiang Xuewei , Chen Yu , Yuan Yue , Zheng Lu 
Published: January 2020

Abstract
The structural details of cellulose I β were discussed according to molecular dynamics simulations with the GLYCAM-06 force field. The simulation outcomes were in agreement with previous experimental data, including structural parameters and hydrogen bond pattern at 298 K. We found a new conformation of cellulose Iβ existed at the intermediate temperature that is between the low and high temperatures. Partial chain rotations along the backbone direction were found and conformations of hydroxymethyl groups that alternated from tg to either gt or gg were observed when the temperature increased from 298 K to 400 K. In addition, the gg conformation is preferred than gt. For the structure adopted at high temperature of 500 K, major chains were twisted and two chains detached from each plain. In contrast to the observation under intermediate temperature, the population of hydroxymethyl groups in gt exceeded that in gg conformation at high temperature. In addition, three patterns of hydrogen bonding were identified at low, intermediate and high temperatures in the simulations. The provided structural information indicated the transitions occurred around 350 K and 450 K, considered as the transitional temperatures of cellulose Iβ in this work.
A survey of outpatient Internal Medicine clinician perceptions of diagnostic error
Authors: Matulis John C. , Kok Susan N. , Dankbar Eugene C. , Majka Andrew J. 
Published: January 2020

Abstract

Background
Little is known about how practicing Internal Medicine (IM) clinicians perceive diagnostic error, and whether perceptions are in agreement with the published literature.

Methods
A 16-question survey was administered across two IM practices: one a referral practice providing care for patients traveling for a second opinion and the other a traditional community-based primary care practice. Our aim was to identify individual- and system-level factors contributing to diagnostic error (primary outcome) and conditions at greatest risk of diagnostic error (secondary outcome).

Results
Sixty-five of 125 clinicians surveyed (51%) responded. The most commonly perceived individual factors contributing to diagnostic error included atypical patient presentations (83%), failure to consider other diagnoses (63%) and inadequate follow-up of test results (53%). The most commonly cited system-level factors included cognitive burden created by the volume of data in the electronic health record (EHR) (68%), lack of time to think (64%) and systems that do not support collaboration (40%). Conditions felt to be at greatest risk of diagnostic error included cancer (46%), pulmonary embolism (43%) and infection (37%).

Conclusions
Inadequate clinician time and sub-optimal patient and test follow-up are perceived by IM clinicians to be persistent contributors to diagnostic error. Clinician perceptions of conditions at greatest risk of diagnostic error may differ from the published literature.

Abstract
To analyze the chemical composition and evaluate the potential commercial value of Dalbergia odorifera leaves, the chemical component and content of the essential oils (EOs), fatty acids (FAs), polyphenols and flavonoids in the leaves of D. odorifera were studied. The composition of the EOs obtained by simultaneous distillation extraction (SDE) (at the yield of 0.092%) and hydro-distillation (HD) (at the yield of 0.050%) from D. odorifera leaves was analyzed by gas chromatography-mass spectrometry (GC-MS). Seventy-six compounds were identified and the major compounds were phytol (22.5–24.3%), 4-vinylguaiacol (8.7–12.7%), dihydroedulan II (7.4–11.2%), γ-elemene (5.1–6.2%), cedrol (2.8–6.1%), coumaran (0.9–3.1%) and hexahydrofarnesyl acetone (2.5–2.7%). The FA yield extracted by ultrasound was 1.145% (w/w), and the most abundant FA components were palmitic acid (C16:0), oleic acid (C18:1) and linoleic acid (C18:2) in leaves. The results of the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis (3-ethylbenzothiazoli-ne-6-sulfonic acid (ABTS+) radical scavenging experiments demonstrated that the EOs and FAs possess strong antioxidant activity. The ethanol extract of the leaves had a high polyphenol content [16.00 mg gallic acid equivalent (GAE) g−1 dry weight (DW)] and flavonoid content [8.92 mg rutin equivalent (RE) g−1 DW]. This research has determined qualitatively and quantitatively the isoflavonoids (biochanin A, isoliquiritigenin, tectorigenin and genistein) by ultra-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS/MS). The phytochemical analysis (EOs, FAs and flavonoids) of the extract showed that the D. odorifera leaf is a rich source of high bioactive compounds and might have the potential to be recommended for further cosmetics, food and pharmaceutical applications.
Septin architecture and function in budding yeast
Authors: Farkašovský Marian 
Published: January 2020

Abstract
The septins constitute a conserved family of guanosine phosphate-binding and filament-forming proteins widespread across eukaryotic species. Septins appear to have two principal functions. One is to form a cortical diffusion barrier, like the septin collar at the bud neck of Saccharomyces cerevisiae, which prevents movement of membrane-associated proteins between the mother and daughter cells. The second is to serve as a polymeric scaffold for recruiting the proteins required for critical cellular processes to particular subcellular areas. In the last decade, structural information about the different levels of septin organization has appeared, but crucial structural determinants and factors responsible for septin assembly remain largely unknown. This review highlights recent findings on the architecture and function of septins and their remodeling with an emphasis on mitotically dividing budding yeasts.

Published: January 2020

Abstract
Genetic variance within the genotype of population and its mapping to phenotype variance in a systematic and high throughput manner is of interest for biodiversity and breeding research. Beside the established and efficient high throughput genotype technologies, phenotype capabilities got increased focus in the last decade. This results in an increasing amount of phenotype data from well scaling, automated sensor platform. Thus, data stewardship is a central component to make experimental data from multiple domains interoperable and re-usable. To ensure a standard and comprehensive sharing of scientific and experimental data among domain experts, FAIR data principles are utilized for machine read-ability and scale-ability. In this context, BrAPI consortium, provides a comprehensive and commonly agreed FAIRed guidelines to offer a BrAPI layered scientific data in a RESTful manner. This paper presents the concepts, best practices and implementations to meet these challenges. As one of the worlds leading plant research institutes it is of vital interest for the IPK-Gatersleben to transform legacy data infrastructures into a bio-digital resource center for plant genetics resources (PGR). This paper also demonstrates the benefits of integrated database back-ends, established data stewardship processes, and FAIR data exposition in a machine-readable, highly scalable programmatic interfaces.
Pivots of the Caribbean? Low-back vowels in eastern Caribbean English
Authors: Walker James A. , Meyerhoff Miriam 
Published: January 2020

AbstractResolving the convergence of low-back vowels in English constitutes a pivot with repercussions for the rest of the vowel system. We consider how speakers on an eastern Caribbean island co-opt the inherent variability of vowel systems to differentiate themselves. Examining the vowels of Bequia English (St. Vincent and the Grenadines) shows the main source of variation to lie in the position and duration of four low back vowels (cloth, lot, palm, thought), which do not act as the same pivot point for realignment of the vowel space as in North American English. The crucial distinction between transmission and diffusion lies at the heart of our findings: principles of language change derived from varieties characterized by transmission may differ from principles associated with histories of diffusion central to many contact and creole varieties.

Published: January 2020

Abstract
Semiaquatic habits evolved in several Sigmodontinae rodent species, but this issue remains poorly studied. The marsh rat Holochilus vulpinus (Brants, 1827) has been associated with palustrine wetland environments and exhibits several morphological traits related to the semiaquatic habit. However, its swimming behavior and the way its morphological specializations contribute to it have not been evaluated so far in this species. This note focuses on describing and quantifying the swimming behavior and swimming performance of H. vulpinus. In order to address these issues, five individuals of H. vulpinus, four adults and one subadult, were filmed while swimming and their performance was quantified. The obtained results indicate that the swimming mode is bipedal paddling, alternating the stroke of the hind feet. The quantitative indicators also qualify H. vulpinus as a good swimmer compared to other terrestrial and semiaquatic mammals.
On a new convergence in topological spaces
Authors: Ruan Xiao-jun , Xu Xiao-quan 
Published: January 2020

Abstract
In this paper, we introduce a new way-below relation in T0 topological spaces based on cuts and give the concepts of SI2-continuous spaces and weakly irreducible topologies. It is proved that a space is SI2-continuous if and only if its weakly irreducible topology is completely distributive under inclusion order. Finally, we introduce the concept of 𝓓-convergence and show that a space is SI2-continuous if and only if its 𝓓-convergence with respect to the topology τSI2(X) is topological. In general, a space is SI-continuous if and only if its 𝓓-convergence with respect to the topology τSI(X) is topological.

Published: January 2020

Abstract
The reinforcing effect of graphene oxide (GO) in enhancing the flexural strength and flexural modulus of aramid fiber (AF)/epoxy composites were investigated with GO-AFs at a weight fraction of 0.1-0.7%. The flexural strength and flexural modulus of the composite reached 87.16 MPa and 1054.7 MPa, respectively, which were about 21.19% and 40.86% higher than those of the pure epoxy resin, respectively. In addition, the flexural properties and interfacial shear strength (IFSS) of composite reinforced by GO-AFs were much higher than the composites reinforced by AFs due to GO improved the interfacial bonding between the reinforcement material and matrix.
A complete overview of REEP1: old and new insights on its role in hereditary spastic paraplegia and neurodegeneration
Authors: Guglielmi Alessio 
Published: January 2020

Abstract
At the end of 19th century, Adolf von Strümpell and Sigmund Freud independently described the symptoms of a new pathology now known as hereditary spastic paraplegia (HSP). HSP is part of the group of genetic neurodegenerative diseases usually associated with slow progressive pyramidal syndrome, spasticity, weakness of the lower limbs, and distal-end degeneration of motor neuron long axons. Patients are typically characterized by gait symptoms (with or without other neurological disorders), which can appear both in young and adult ages depending on the different HSP forms. The disease prevalence is at 1.3–9.6 in 100 000 individuals in different areas of the world, making HSP part of the group of rare neurodegenerative diseases. Thus far, there are no specific clinical and paraclinical tests, and DNA analysis is still the only strategy to obtain a certain diagnosis. For these reasons, it is mandatory to extend the knowledge on genetic causes, pathology mechanism, and disease progression to give clinicians more tools to obtain early diagnosis, better therapeutic strategies, and examination tests. This review gives an overview of HSP pathologies and general insights to a specific HSP subtype called spastic paraplegia 31 (SPG31), which rises after mutation of REEP1 gene. In fact, recent findings discovered an interesting endoplasmic reticulum antistress function of REEP1 and a role of this protein in preventing τ accumulation in animal models. For this reason, this work tries to elucidate the main aspects of REEP1, which are described in the literature, to better understand its role in SPG31 HSP and other pathologies.

Water-Oxidation Electrocatalysis by Manganese Oxides: Syntheses, Electrode Preparations, Electrolytes and Two Fundamental Questions
Authors: Melder Jens , Bogdanoff Peter , Zaharieva Ivelina , Fiechter Sebastian , Dau Holger , Kurz Philipp 
Published: January 2020

Abstract
The efficient catalysis of the four-electron oxidation of water to molecular oxygen is a central challenge for the development of devices for the production of solar fuels. This is equally true for artificial leaf-type structures and electrolyzer systems. Inspired by the oxygen evolving complex of Photosystem II, the biological catalyst for this reaction, scientists around the globe have investigated the possibility to use manganese oxides (“MnOx”) for this task. This perspective article will look at selected examples from the last about 10 years of research in this field. At first, three aspects are addressed in detail which have emerged as crucial for the development of efficient electrocatalysts for the anodic oxygen evolution reaction (OER): (1) the structure and composition of the “MnOx” is of central importance for catalytic performance and it seems that amorphous, MnIII/IV oxides with layered or tunnelled structures are especially good choices; (2) the type of support material (e.g. conducting oxides or nanostructured carbon) as well as the methods used to immobilize the MnOx catalysts on them greatly influence OER overpotentials, current densities and long-term stabilities of the electrodes and (3) when operating MnOx-based water-oxidizing anodes in electrolyzers, it has often been observed that the electrocatalytic performance is also largely dependent on the electrolyte’s composition and pH and that a number of equilibria accompany the catalytic process, resulting in “adaptive changes” of the MnOx material over time. Overall, it thus has become clear over the last years that efficient and stable water-oxidation electrolysis by manganese oxides can only be achieved if at least four parameters are optimized in combination: the oxide catalyst itself, the immobilization method, the catalyst support and last but not least the composition of the electrolyte. Furthermore, these parameters are not only important for the electrode optimization process alone but must also be considered if different electrode types are to be compared with each other or with literature values from literature. Because, as without their consideration it is almost impossible to draw the right scientific conclusions. On the other hand, it currently seems unlikely that even carefully optimized MnOx anodes will ever reach the superb OER rates observed for iridium, ruthenium or nickel-iron oxide anodes in acidic or alkaline solutions, respectively. So at the end of the article, two fundamental questions will be addressed: (1) are there technical applications where MnOx materials could actually be the first choice as OER electrocatalysts? and (2) do the results from the last decade of intensive research in this field help to solve a puzzle already formulated in 2008: “Why did nature choose manganese to make oxygen?”.

Abstract
Gonzalez, AM, Pinzone, AG, Bram, J, Salisbury, JL, Lee, S, and Mangine, GT. Effect of multi-ingredient preworkout supplementation on repeated sprint performance in recreationally active men and women. J Strength Cond Res 34(4): 918–923, 2020—The purpose of this investigation was to examine the effects of acute supplementation of a multi-ingredient preworkout supplement (MIPS), containing a proprietary blend of ancient peat and apple extracts, creatine monohydrate, taurine, ribose, and magnesium, on sprint cycling performance. Seventeen recreationally active men and women (23.2 ± 5.9 years; 172.9 ± 14.3 cm; 82.4 ± 14.5 kg) underwent 2 testing sessions administered in a randomized, counterbalanced, double-blind fashion. Subjects were provided either MIPS or placebo (PL) one hour before performing a sprint cycling protocol, which consisted of ten 5-second “all-out” sprints interspersed by 55 seconds of unloaded pedaling. Average power (PAVG), peak power (PPK), average velocity (VAVG), and distance covered were recorded for each sprint. Separate linear mixed models revealed decrements (p < 0.05) compared to the first sprint in PAVG (75–229 W) and PPK (79–209 W) throughout all consecutive sprints after the initial sprint during PL. Likewise, diminished (p ≤ 0.029) VAVG (3.37–6.36 m·s−1) and distance covered (7.77–9.00 m) were noted after the third and fifth sprints, respectively, during PL. By contrast, during MIPS, only VAVG decreased (2.34–5.87 m·s−1, p ≤ 0.002) on consecutive sprints after the first sprint, whereas PAVG and PPK were maintained. In addition, a significant decrease (p = 0.045) in distance covered was only observed on the ninth sprint during MIPS. These data suggest that recreational athletes who consumed the MIPS formulation, one hour before a repeated sprinting session on a cycle ergometer, better maintained performance compared with PL.
