Resistive switching device with highly-asymmetric current-voltage characteristics: its error analysis and new design parameter

As a solution to future non-volatile random access memories (NV-RAMs) with large scale integration, many researchers are studying a crossbar array built with many resistive switching cells because of its simple architecture and scalability. However, a sneak current in the crossbar array that energizes memory cells not explicitly selected, raises various issues that need to be addressed for commercialization. Hence, we clearly describe the dominant causes and considerations for a passive crossbar array based on memristors. We discover that such resistive switches under reverse bias along the sneak current paths can play an important role to minimize the overall sneak current by blocking their reverse current. To develop commercializable passive crossbar resistive switching arrays, we demonstrate a read error bound and propose a new design parameter (RRL/RFL as ratio of reverse low resistance state and forward low resistance state) using the switching resistances on the forward and reverse current paths.
Moralvorstellungen von Lernenden und ihre metaphorische Strukturierung : Eine kognitionslinguistische Analyse von Denkwelten zur Nutztierhaltung und zum Fleischkonsum im Biologieunterricht

Eva (15 J.) explains, why animals can be eaten: „The human being is at the top of the world and can decide about everything and he evolved continuously. I think that puts humans above animals. “ Our study is based on the hypothesis that moral conceptions are structured by metaphors. These findings result from 15 interviews about livestock farming and consumption of meat. Therefore, we explored characteristic students’ conceptions and examined metaphors within moral arguments and judgments by qualitative content analyses. 76 N. A. Tramowsky & J. Groß Resulting from this, we generated 4 educational reconstructed learning environments which are used in 5 teaching experiments. The results show how different moral arguments and judgments can be made by persons who eat meat and those who do not. In this article, it is discussed how metaphors decide about moral thinking and how they can be helpful to create fruitful learning environments.
Hydrothermal deposition of CoFe2o4 with a micro nano binary structure onto a wood surface with related magnetic property and microwave absorption

In this study, magnetic CoFe2O4 with a micro/nano binary structure was deposited onto a wood surface using a hydrothermal process. Several samples of CoFe2O4-modified wood composites were obtained by varying the initial parameters of the process. The morphology and structure of the samples demonstrated the influence of varying temperature during the hydrothermal process. The results indicated that CoFe2O4 particles, which comprise a variety of microscale and nanoscale structures, precipitated on the wood surface through the Ostwald ripening process under alkali treatment. Additionally, temperature was found to be a critical factor that influenced the resultant morphology, magnetic property, and microwave absorption property of the CoFe2O4-modified wood. Moreover, the CoFe2O4-modified wood had a high saturation magnetization (Ms) of 30.7 emu·g−1 and a minimum value of reflection of −16.2 dB at 16.6 GHz at room temperature. This work suggested that the CoFe2O4-modified wood composites can be used to design and manufacture microwave absorbers.
Identification of phenanthrene and pyrene degrading bacteria from used engine oil contaminated soil

The purpose of the study was to identify effective bacteria that degrade phenanthrene and pyrene from used engine oil contaminated soil. A total of 93 bacterial isolates were obtained and their degradations were determined. Based on culture-depended technique and tested for in vitro phenanthrene and pyrene degradations using spray plate technique and colorimetric assay with 2,6-dichloroindophenol (DCPIP). Fifty three isolates shows evidence of 5 g/l phenanthrene degradation within 72 hours in spray plate technique. Further 23 isolates were selected from 53 isolates after the colorimetric screening. Biodegradation study shows two isolates named MM045 and MM087 with 75.2% and 80.2% degradations for 500 mg/l phenanthrene and also 54.3% and 59.7% of 250 mg/l pyrene degradations within 24 hours respectively. These isolates were identified as Cronobacter sakazakii strain MM045 (Accession number: KT933253) and Enterobacter specie strain MM087 (Accession number: KT933254) using 16S rRNA gene sequencing and neighbour joining tree analyses. The identified isolates were proven to be fast effective in degrading high concentrations of phenanthrene and pyrene as their sole carbon and energy sources.
Development of TiO2-Carbon Composite Acid Catalyst for Dehydration of Fructose to 5-Hydroxymethylfurfural

A TiO2-Carbon (TiO2C) composite was prepared using the microwave-assisted method and sulfonated using fuming sulfuric acid to produce a TiO2C solid acid catalyst. The prepared solid acid catalyst was characterised using scanning electron microscopy, Brunauer-Emmett-Teller analysis, Fourier transform infrared spectroscopy, and X-ray diffraction. Crystallinity analysis confirmed that TiO2C has an anatase structure, while analysis of its morphology showed a combination of spheres and particles with a diameter of 50 nm. The TiO2C solid acid catalyst was tested for use in the catalytic dehydration of fructose to 5-hydroxymethylfurfural (5-HMF). The effect of reaction time, reaction temperature, catalyst dosage, and solvent were investigated against the 5-HMF yield. The 5-HMF yield was found to be 90% under optimum conditions. The solid acid catalyst is very stable and can be reused for four catalytic cycles. Hence, the material has great potential for use in industrial applications and can be used for the direct conversion of fructose to 5-HMF because of its high activity and high reusability.
Identificación no lineal de movimientos sísmicos en el lecho rocoso ingenieril a partir de registros tomados en la superficie

In earthquake engineering, only ground surface records are usually available, and the lower layers motions must be estimated by knowing the stratigraphic profile. This is relevant in earthquake-resistant design of structures with underground parts, irregular soils, and soil-structure interaction. If the soil behavior is linear, the aforementioned estimation is an equivalent linear deconvolution; however, in actual situations, especially for severe earthquakes, this behavior is non-linear, and, thus, more sophisticated procedures are required. This paper presents an algorithm to estimate, after superficial records, the motion of the lower layers. The aforementioned soil non-linear behavior is represented by a modified Masing model, in which rigidity and damping depend on the transverse deformation. The domain to be analyzed is discretized in layers; the ensuing equations of motion are solved in discrete time by the Newmark method. Given that this problem is illconditioned, a UKF (Unscented Kalman Filter) is utilized to estimate the solution.
Sawdust-Derived Biochar Much Mitigates VFAs Accumulation and Improves Microbial Activities To Enhance Methane Production in Thermophilic Anaerobic Digestion

Sawdust-derived biochar (SDBC) was added to an anaerobic digester at 15g/L for thermophilic codigestion under semicontinuous operation for more than 130 days. With a stepwise increase of organic loading rate (OLR) from 1.6 to 5.4 gVS/L·d–1, steady CH4 yields achieved between 462.3 and 500.1 mL/gVS. In contrast, for the control digester (without biochar addition) and another digester added with sewage sludge-derived biochar (SSBC), a steady working condition could only be maintained for about 80 days with OLR and CH4 yields up to 2.7 gVS/L·d–1 and 322.3–337.9 mL/gVS, respectively. The total volatile fatty acids (VFAs) accumulation up to about 30gCOD/L tended to be the threshold to restrain steady CH4 production, but this occurred much earlier for the control and SSBC digesters at much lower OLR. By batch experiments of digestion in a methanogenesis inhibition condition and with propionate or butyrate as the sole substrate, it was found that with SDBC addition, the substrate was oxidized steadily in the 40-.
Systematic Extraction of Analogue Series from Large Compound Collections Using a New Computational Compound–Core Relationship Method

Chemical optimization of organic compounds produces a series of analogues. In addition to considering an analogue series (AS) or multiple series on a case-by-case basis, which is often done in the practice of chemistry, the extraction of analogues from compound repositories is of high interest in organic and medicinal chemistry. In organic chemistry, ASs are a source of alternative synthetic routes and also aid in exploring relationships between compounds from different sources including synthetic vs. naturally occurring molecules. In medicinal chemistry, ASs are the major source of structure–activity relationship information and of hits or leads for drug development. ASs might be identified in different ways. For a given reference compound, a substructure search can be carried out using its scaffold. Alternatively, matched molecular pairs can be calculated to retrieve analogues from a compound repository. However, if no query compounds are used, the identification of ASs in databases is a difficult task. Herein, we introduce a computational approach to systematically identify ASs in collections of organic compounds. The approach involves compound decomposition on the basis of well-established retrosynthetic rules, organization of compound–core relationships, and identification of analogues sharing the same core. The method was applied on a large scale to extract ASs from the ChEMBL database, yielding more than 30 000 distinct series.

Novel Green Micro-Synthesis of Graphene-Titanium Dioxide Nano- Composites with Photo-Electrochemical Properties

Graphene-Titanium dioxide nano-composite forms a very promising material in the field of photo-electrochemical research. In this study, a novel environment-friendly synthesis method was developed to produce well-distributed anatase nano-titanium dioxide spherical particles on the surface of graphene sheets. This novel method has great advantages over previously developed methods of producing graphenetitanium dioxide nanocomposites (GTNCs). High calcination temperature 650°C was used in the preparation of nano titanium dioxide, and chemical exfoliation for graphene synthesis and GTNC was performed by our novel method of depositing titanium dioxide nanoparticles on graphene sheets using a Y-shaped micro-reactor under a controlled pumping rate with minimal use of chemicals. The physiochemical and crystallographic properties of the GTNC were confirmed by TEM, XRD, FTIR and EDX measurements, confirming process repeatability. Spherical nano-titanium dioxide was produced in the anatase phase with very high crystallinity and small particle diameters ranging from 9 nm to 25 nm, also the as prepared graphene (RGO) exhibited minimal flake folding and a high carbon content of 81.28% with a low oxygen-to-carbon atomic ratio of 0.172 and GTNCs produced by our novel method had a superior loading content, a homogeneous distribution and a 96.6% higher content of titanium dioxide particles on the graphene sheets compared with GTNCs prepared with the one-pot method. For its photoelectrochemical properties, chronoamperometry showed that GTNC sample (2) had a higher peak current of 60 μA compared with that of GTNC sample (1), which indicates that the separation and transfer of electron-hole pairs are better in the case of GTNC sample (2) and according to the LSV results, the generation of photocurrent in the samples can be observed through multiple on-off cycles, which indicates that the electrodes are stable and that the photocurrent is quite reversible.
Full 3D Printing of Stretchable Piezoresistive Sensor with Hierarchical Porosity and Multimodulus Architecture

A soft piezoresistive sensor with its unique characteristics, such as human skin, light weight, and multiple functions, yields a variety of possible practical applications to skin‐attachable electronics, human–machine interfaces, and electronic skins. However, conventional filler‐matrix piezoresistive sensors often suffer from unsatisfactory sensitivity or insufficient measurement range, as well as significant cross‐correlation between out‐of‐plane pressure and in‐plane extension. Here, a stretchable piezoresistive sensor (SPS) is realized by combining a hierarchically porous sensing element with a multimodulus device architecture via a full 3D printing process. As a result, the sensor exhibits high sensitivity (5.54 kPa−1), large measurement range (from 10 Pa to 800 kPa), limited cross‐correlation, and excellent durability. Meanwhile, benefiting from the porous structure and mechanical mismatch design, which efficiently distributes the stress away from the sensing element, the device experiences only 7% resistance change at 50% stretching. This approach is employed to rapidly program and readily manufacture stylish, all‐in‐one, functional devices for various applications, demonstrating that the technique is promising for customized stretchable electronics.
MLP Based Tan-Sigmoid Activation Function for Cardiac Activity Monitoring

Cardiac abnormalities can occur to everyone, irrespective of race, age or gender. However, family history gives a clear signal of the probable probability of heart failure in the heart. Cardiac abnormalities rarely show early symptoms, thereby contributing to sudden deaths in patients. In general, heartbeat is an irregular electric boost or heart activity. In this paper, an early monitoring system for detecting cardiac abnormalities was conducted using the Multilayer Perceptron (MLP) network. The cardiac abnormalities dataset is taken from the MIT-BIH database used to train the MLP network by using multiple training algorithms with Tan-Sigmoid as an activation function.
Role of α-MSH-MC1R-cAMP Signaling Pathway in Regulating the Melanin Synthesis in Silky Fowl

α-Melanocyte stimulating hormone (α-MSH) is a neuroendocrine regulatory peptide containing 13 amino acids derived from proopiomelanocortin (POMC), with an amino acid sequence of SerTyr-Ser-Met-Glu-Glu-Phe-Arg-Trp-Gly-Lys-Pro-Val [3]. The melanocortin 1 receptor (MC1R) gene is encoded by an extension locus in mammals, and the corresponding encoded protein with seven transmembrane domains is a melanocytic Gs protein-coupled receptor crucial for the regulation of melanocyte proliferation and function [4,5].
Zinc(II) as a Versatile Template for Efficient Dipolar and Octupolar Second-Order Nonlinear Optical Molecular Materials §

This short review outlines the main results obtained in the field of molecular materials based on zinc coordination compounds for second-order nonlinear optics. It presents an overview of the main classes of second-order nonlinear optical (NLO) active complexes bearing monodentate, bidentate, tridentate, or tetradentate π-delocalized ligands such as substituted stilbazoles, bipyridines, phenanthrolines, terpyridines, and Schiff bases. Macrocyclic ligands such as porphyrins and phthalocyanines are not covered. This paper shows how coordination to the Zn(II) center of π-delocalized nitrogen donor ligands produces a significant enhancement of their quadratic hyperpolarizability. Dipolar complexes are mainly presented, but octupolar zinc complexes are also presented. The coverage is mainly focused on NLO properties that are measured at the molecular level, working in solution, by means of the electric field-induced second harmonic generation (EFISH) or the hyper-Rayleigh scattering (HRS) techniques.
The Structure of Contracts and Transaction Costs: A Note

It is the purpose of this note to consider the determinants of contract provisions, in particular those that stipulate possible actions in the event of the breach of the terms in a credit contract. This category of provisions is generally called "creditors' remedies" when used in credit contracts. The use of creditors' remedies, collateral in particular, to reduce the likelihood of loan default has been examined in earlier papers [1,2]. Robert Barro's paper [1, p. 455] in concluding, suggested that "Useful extensions to the model would include generalizations to the form of the loan contract, introduction to other types of transactions, costs, and analysis of the loan period. " Although we do not extend Barro's model, we do extend some of his concepts in the direction suggested. In particular we will show that a theory based on nonzero information costs is capable of explaining the observed variation in the form or structure of credit contracts and their use of explicit remedies.
