Monitoring the Early Strength Development of Cement Mortar with Piezoelectric Transducers Based on Eigenfrequency Analysis Method

Monitoring the early strength formation process of cement is of great importance for structural construction management and safety. In this study, we investigated the relationship between the eigenfrequency and the early strength development of cement mortar. Embedded piezoceramic-based smart aggregates recorded the early strength of cement mortar. An eigenfrequency analysis model demonstrated the relationship between strength and frequency. Experiments were performed by using piezoelectric transducers to monitor the early strength formation process during the testing period. Three types of specimens with different strength grades were tested, and the early strength formation processes were recorded. The experimental results demonstrate that cement mortar strength has a good linear relationship with the resonance frequency, and the average square of the correlation coefficient is greater than 0.98. The results show that structural health monitoring technology is a feasible method of assessing structural safety conditions and has a broad market in the structural construction industry.
Merced Proceedings of the Annual Meeting of the Cognitive Science Society Title Understanding User Behavior Using Cognitive Models Permalink

We consider the application of cognitive models to a range of problems in mobile telecommunications. In particular, consideration is given to the characteristic patterns that emerge in how people use mobile content in a natural environment. Using cognitive models drawn from the literature on decisionmaking, preference and semantics, we show that the mobile content environment possesses a range of interesting psychological properties, which can be used to further both pure and applied research goals.
Dynamics of the Zebrafish Skeleton in Three Dimensions During Juvenile and Adult Development

Zebrafish are a valuable model for normal vertebrate skeletogenesis and the study of myriad bone disorders. Bones grow, ossify and change shape throughout the zebrafish lifetime, and 3D technologies allow us to examine skeletogenic processes in detail through late developmental stages. To facilitate analysis of shape, orientation and tissue density of skeletal elements throughout ontogeny and adulthood, we generated a high-resolution skeletal reference dataset of wild-type zebrafish development. Using microCT technology, we produced 3D models of the skeletons of individuals ranging from 12 to 25 mm standard length (SL). We analyzed the dynamics of skeletal density and volume as they increase during juvenile and adult growth. Our resource allows anatomical comparisons between meristic units within an individual—e.g., we show that the vertebral canal width increases posteriorly along the spine. Further, structures may be compared between individuals at different body sizes: we highlight the shape changes that the lower jaw undergoes as fish mature from juvenile to adult. We show that even reproductively mature adult zebrafish (17–25 mm SL) continue to undergo substantial changes in skeletal morphology and composition with continued adult growth. We provide a segmented model of the adult skull and a series of interactive 3D PDFs at a range of key stages. These resources allow changes in the skeleton to be assessed quantitatively and qualitatively through late stages of development, and can serve as anatomical references for both research and education.
Burgh, Gilbert/Thornton, Simone (eds.) (2019): Philosophical inquiry with children: The development of an inquiry society in Australia, London/New York: Routledge.

A group of philosophers in Australia inspired by the work of Matthew Lipman and Margret Sharp (1980) set out to teach philosophy in schools. Their efforts over about thirty years led to the development of an inquiry society in Australia. While this is an ambitious task and many efforts are moving in opposition such as curriculum efforts that were and are excessively career-oriented and, to that extent, anti-intellectual, this group of philosophers, educators, administrators, and classroom teachers continued toward the goal of an inquiry society. This book creatively integrates several strains of this development in a more or less chronological manner.
Fall 11-14-2017 State-based Peridynamic Particle Method

In this study, a novel discrete Peridynamics framework called the “State-Based Peridynamic Particle Model (SPPM)” is introduced. In this approach, a solid body is simulated by neither solving differential equations nor integral equations; instead, the simulation is accomplished by directly solving discrete systems of equations using finite summations. SPPM is formulated for a random distribution of particles, hence, it can be considered as a meshfree method. The assumptions of continuity and homogeneity are not necessary in this approach. The SPPM is a generalization of the “State-Based Peridynamic Lattice Model (SPLM)”. In the SPLM formulation, for sake of simplicity and computational efficiency, a lattice of particles is employed and the horizon size is fixed. The proposed SPLM approach differs from the previous versions in that the procedures for calculating the bond forces, damage and plasticity are improved. A novel and robust damage approach called the “Two Spring Damage Model”, with the capability of modeling partial damage, is also proposed and developed for the SPPM and the SPLM. The re-formulated SPLM method is then calibrated and employed to simulate concrete structures. The obtained results are compared with the previous SPLM versions, experimental tests, and the commercial finite element software, Abaqus. The advantages and difficulties of each modeling approach are described. The re-formulated SPLM demonstrates significant improvements over the previous versions. The obtained simulation results indicate that the SPLM approach produces similar, and in some ways more realistic results than the well-developed Abaqus methods, but is much simpler to understand and use. The obtained results also reasonably replicate the available laboratory data.
High‐Performance Flexible Broadband Photodetector Based on Organolead Halide Perovskite

Organolead halide perovskites have attracted extensive attentions as light harvesting materials for solar cells recently, because of its high charge‐carrier mobilities, high photoconversion efficiencies, low energy cost, ease of deposition, and so on. Herein, with CH3NH3PbI3 film deposited on flexible ITO coated substrate, the first organolead halide perovskite based broadband photodetector is demonstrated. The organolead halide perovskite photodetector is sensitive to a broadband wavelength from the ultraviolet light to entire visible light, showing a photo‐responsivity of 3.49 A W−1, 0.0367 A W−1, an external quantum efficiency of 1.19×103%, 5.84% at 365 nm and 780 nm with a voltage bias of 3 V, respectively. Additionally, the as‐fabricated photodetector exhibit excellent flexibility and robustness with no obvious variation of photocurrent after bending for several times. The organolead halide perovskite photodetector with high sensitivity, high speed and broad spectrum photoresponse is promising for further practical applications. And this platform creates new opportunities for the development of low‐cost, solution‐processed and high‐efficiency photodetectors.
Quantitative analysis of camptothecin , total phenolic , flavonoid content and antioxidant activity of Nothapodytes nimmoniana collected from different geographical locations

Nothapodytes nimmoniana is an endangered medicinal tree endemic to Western Ghats, India and it is one of the important sources for large scale isolation of camptothecin (CPT), a potent antitumor compound. Camptothecin is a monoterpenoid indole alkaloid isolated from various plant species such as Ophiorrhiza mungo, Ervatomia hyneana, Nothapodytes nimmoniana etc. The plant extracts has shown various activities such as antimicrobial activity, anti-malarial activity, anti-inflammatory activity, antitumor/cytotoxic activity, anti-oxidant activity, etc. In the present study, N. nimmoniana samples were collected from different geographical locations viz., Amboli, Joida, Jamboti, Panhala and Ulvi of Karnataka and Maharashtra regions and evaluated for camptothecin content, quantitative estimation of total phenolic, flavonoid content and their anti-oxidative potential. The leaves and stem samples were dried, powdered and extracted with five different solvents (Petroleum benzene, Ethyl acetate, Methanol, Butanol, and Water) and accessed for quantitative analysis. Samples were also extracted and analyzed for camptothecin content using HPLC. The antioxidant activity of N. nimmoniana was also assessed by DPPH, reducing power and phosphomolybdenum assay. Varied results were observed with different solvents and samples collected from different locations. Aqueous extract of leaf sample from Amboli and aqueous extract of stem sample from Ulvi showed highest phenolic content (11.25g GAE/ 100g and 5.20g GAE/100g) respectively. Highest flavonoid content were observed from aqueous extract of leaf and stem samples collected from Joida and Jamboti (2.07g QE/100g and 1.06g QE/100g) respectively. Among the leaf samples collected from different locations, aqueous extract from Joida showed highest radical scavenging activity of 99.86% followed by aqueous extract from amboli (99.36%), and the lowest activity was observed in the ethyl acetate extract from Joida. Among stem samples, Ethyl acetate showed highest activity with 98.69% and lowest being sample from Jamboti with 14.56%. Reducing power of ethyl acetate extract showed highest while methanol extracts being the lowest among leaf samples. Among stem samples, Butanol extract showed highest activity while aqueous extract showed lowest activity. In Phosphomolybdenum method, butanol extract from amboli showed highest activity in both leaf and stem samples. The highest content of camptothecin was obtained from the stem samples collected from Panhala with 749 μg/g DW and lowest being from Amboli with 130μg/g DW. Among leaf samples, camptothecin content was highest from Amboli with 160 μg/g DW and lowest being from Panhala with 50μg/g DW.
REMOVAL OF ACETIC ACID FROM DILUTE AQUEOUS SOLUTIONS USING ZEOLITE 13 X

In this study, acetic acid adsorption equilibrium and kinetics of 13X synthetic zeolite from aqueous solutions at 25, 35 and 45 °C were investigated. 13X particles (particle diameter in the range of 75150 m) were contacted with different initial acetic acid cocentrations in aqueous phases (0.23 wt. %) at constant temperature in a batch reactor. Acetic acid concentrations of the liquid samples taken from the adsorption mixtures at specific time intervals were measured by titration with NaOH solution and the time required for the system to reach equilibrium and acetic acid amounts adsorbed at equilibrium were determined. The experimental adsorption kinetics data was best represented by the pseudo-second order model and the model parameters were calculated. The experimental equilibrium data was fitted to the Sips model and the model parameters were calculated. Adsorption thermodynamic parameters (standard Gibbs free energy change, enthalpy change, and entropy change of adsorption) were determined. The acetic acid-saturated adsorbent was regenerated by two methods in order to evaluate its reusability. Adsorption of acetic acid on 13X led to appearance of new bands in at 1390, 1472 and 1593 cm in the transmittance infrared spectrum which were assigned to the acetate ions. Regeneration of the acetic acid-saturated 13X in deionized water at 45 °C led to loss in intensities of these bands indicating dissolution of the weakly adsorbed species associated with these bands. After heating at 300 °C, the bands at 1472 and 1593 cm disappeared whereas 1390 cm band remained and a very weak shoulder band appeared at 1720 cm.

The numerical results shows a high negative chromatic dispersion of about -389 ps/nm/km and the relative dispersion slope the same as the single mode fiber SMF-28 of about 0.0036nm -1 at wavelength =1.55 μm. these properties make our proposed design usable for several applications such as compensation dispersion and so.
Formation of erosion resistance of gray forest soils in the conditions of Carpathian region

Aim. To study the impact of perennial grasses mixtures on the formation of erosion resistance of gray forest soils of different degradation degree and their unmodifi ed analogues in conditions of long-term permanent experiment. Methods. Field, laboratory, assessment and comparison. Results. It was established that lupine- cereal grass mixtures increased erosion resistance of slope soils considerably within fi fteen years. The sum of soil structural aggregates was improved from satisfactory into good category. There were positive changes in the number of water-resistant aggregates as well. The studies confi rmed a positive impact of legume-grasses on the density and porosity of soil. Soil density was the lowest when the slope was laid down in perennial lupine and its mixture with cereal grasses. The intensifi cation of soil erosion and the approximation of the illuvial horizon level to the surface resulted in the compaction of upper soil layers to 1.29–1.44 g/cc. General porosity of soil correlated with its density which did not exceed optimal values in poorly eroded soils in upper layers. The studies proved the impact of the ways of laying down the slope in grass and the level of soil degradation on its humidity and water permeability. In the experiment conditions, the increase in soil degradation led to the decrease in its moisture. The decrease in the content of humidity in crop fi eld took place at the expense of higher intensity of the growth and water consumption of lupine-cereal grasses in comparison with natural mixed herbs, especially in the periods with a small amount of precipitation. The difference in the upper soil layers was in the range of 0.2–0.5 %. It was established that the highest values of soil water permeability were formed on lupine-cereal grass mixtures in all the variants of degraded soils. Conclusions. Laying down slope lands in perennial lupine in combination with cereal grasses promotes the formation of their higher resistance to erosion processes and restoration of fertility. Perennial legume-cereal mixtures ensure the improvement of structural-aggregate state, total density and porosity of soil, enhance its water supply and water permeability.

Characterization of NAD-Dependent Formate Dehydrogenase from Trametes versicolor Using a Cell-Free Protein Expression System

CO2 emissions are the primary reason for global warming; hence, biological and chemical technologies for converting CO2 into useful compounds are being actively studied. Biological methods using enzymes can convert CO2 under mild conditions. Formate dehydrogenase (FDH) is a representative CO2 conversion enzyme. Its function was revealed after isolation from bacteria, yeast, and plants. In this study, we evaluated the CO2 conversion potential of FDH isolated from wood-rotting fungi. After isolating the FDH gene (TvFDH) from Trametes versicolor, we cloned the full-length FDH from T. versicolor and expressed it in a cell-free expression system. The gene encoding TvFDH was identified as 1,200 bp open reading frame (ORF) and the expected molecular weight of the protein was approximately 42 kDa. Overexpression of the recombinant crude protein including TvFDH was confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Enzyme activities and metabolite analyses confirmed the efficiency of TvFDH for CO2 reduction.
Influence of inherited topography on gravitational slope failure: three‐dimensional numerical modelling of the La Clapière slope, Alpes‐Maritimes, France

Gravitational slope failure involves rock slopes at various scales. Nowadays, it is accepted that different factors influence slope destabilization, including topography. In many cases, slope failure occurs between tributary valleys cutting the slope. In this study, we ask what influence tributary valleys have on slope failure. To tackle this question, we developed a 3‐D numerical model of the La Clapière Slope and then examined a series of simplified 3‐D models with different geometries of tributary valleys (spacing and depth). Our results show that: (1) whatever considered in situ stresses are, including the third dimension reduces the destabilization threshold compared with 2‐D models; and (2) the spacing and the depth of tributary valleys influence slope failure. For shallow incisions, increasing the lateral spacing between tributary valleys does not affect failure localization but does increase slope damage (to a stable value from 2000 m). However, deeper incision does not affect slope damage but does contribute to failure localization. When the spacing is less than 1500 m, the part of the slope between tributary valleys is not involved in the failure process, but for spacings above 1500 m slope failure occurs between tributary valleys.
An integrated omics analysis of eicosanoid biology 1

Eicosanoids have been implicated in a vast number of devastating inflammatory conditions, including arthritis, atherosclerosis, pain, and cancer. Currently, over a hundred different eicosanoids have been identified, with many having potent bioactive signaling capacity. These lipid metabolites are synthesized de novo by at least 50 unique enzymes, many of which have been cloned and characterized. Due to the extensive characterization of eicosanoid biosynthetic pathways, this field provides a unique framework for integrating genomics, proteomics, and metabolomics toward the investigation of disease pathology. To facilitate a concerted systems biology approach, this review outlines the proteins implicated in eicosanoid biosynthesis and signaling in human, mouse, and rat. Applications of the extensive genomic and lipidomic research to date illustrate the questions in eicosanoid signaling that could be uniquely addressed by a thorough analysis of the entire eicosanoid proteome. — Buczynski, M.

Some notes on approaches to regulatory capital assessment for insurance firms

Abstract The intellectual climate around financial solvency regulation has changed markedly since the global financial crisis, especially with regard to the usefulness of market prices, the desirability of principle-based solvency assessment, the feasibility of a probabilistic approach to produce accurate capital estimates, and indeed whether solvency assessment should be risk-sensitive at all. This short paper provides some reflective notes on approaches to solvency capital assessment for insurance firms in this context.
products compatible products + “ Shoes ” Output Shop the Look Complete the Look Query OutputQuery Figure

Modeling fashion compatibility is challenging due to its complexity and subjectivity. Existing work focuses on predicting compatibility between product images (e.g. an image containing a t-shirt and an image containing a pair of jeans). However, these approaches ignore real-world ‘scene’ images (e.g. selfies); such images are hard to deal with due to their complexity, clutter, variations in lighting and pose (etc.) but on the other hand could potentially provide key context (e.g. the user’s body type, or the season) for making more accurate recommendations. In this work, we propose a new task called ‘Complete the Look’, which seeks to recommend visually compatible products based on scene images. We design an approach to extract training data for this task, and propose a novel way to learn the scene-product compatibility from fashion or interior design images. Our approach measures compatibility both globally and locally via CNNs and attention mechanisms. Extensive experiments show that our method achieves significant performance gains over alternative systems. Human evaluation and qualitative analysis are also conducted to further understand model behavior. We hope this work could lead to useful applications which link large corpora of real-world scenes with shoppable products.
