A BioSequence Ontology from Molecular Structure

Gene sequences are a focal point of modern biological research, with applications ranging from diagnostics to gene-driven drug design. An ontology’s automated reasoning capability and traceable logic is sure to be an asset to these efforts. However, current biomedical ontologies fail to achieve this potential. This may partly be due to a lack of formal axiomatization of the underlying molecular structure and mereology of gene sequences, despite an otherwise richly deﬁned vocabulary. In this paper, we propose a new BioSequence Ontology with explicit axiomatization of the underlying path graph structure.
Scaling Performance Analysis and Optimization Based on the Node Spatial Distribution in Mobile Content-Centric Networks

Content-centric networks (CCNs) have become a promising technology for relieving the increasing wireless traffic demands. In this paper, we explore the scaling performance of mobile content-centric networks based on the nonuniform spatial distribution of nodes, where each node moves around its own home point and requests the desired content according to a Zipf distribution. We assume each mobile node is equipped with a finite local cache, which is applied to cache contents following a static cache allocation scheme. According to the nonuniform spatial distribution of cache-enabled nodes, we introduce two kinds of clustered models, i.e., the clustered grid model and the clustered random model. In each clustered model, we analyze throughput and delay performance when the number of nodes goes infinity by means of the proposed cell-partition scheduling scheme and the distributed multihop routing scheme. We show that the node mobility degree and the clustering behavior play the fundamental roles in the aforementioned asymptotic performance. Finally, we study the optimal cache allocation problem in the two kinds of clustered models. Our findings provide a guidance for developing the optimal caching scheme. We further perform the numerical simulations to validate the theoretical scaling laws.
A laser flash photolysis/IR diode laser absorption study of the reaction of chlorine atoms with selected alkanes

A high-resolution IR diode laser in conjunction with a Herriot multiple reflection flow-cell has been used to directly determine the rate coefficients for simple alkanes with Cl atoms at room temperature (298 K). The following results were obtained: k(Cl + n-butane) = (1.91 ′ 0.10) × 10 - 1 0 cm 3 molecule - 1 s - 1 , k(Cl + n-pentane) = (2.46 ′ 0.12) × 10 - 1 0 cm 3 molecule - 1 s - 1 , k(Cl + iso-pentane) = (1.94 ′ 0.10) × 10 - 1 0 cm 3 molecule - 1 s - 1 , k(Cl + neopentane) = (1.01 ′ 0.05) × 10 - 1 0 cm 3 molecule - 1 s - 1 , k(Cl + n-hexane) = (3.44 ′ 0.17) × 10 - 1 0 cm 3 molecule - 1 s - 1 where the error limits are ′1σ. These values have been used in conjunction with our own previous measurements on Cl + ethane and literature values on Cl + propane and Cl + iso-butane to generate a structure activity relationship (SAR) for Cl atom ion reactions based on direct measurements. The resulting best fit parameters are kp = (2.61 ′ 0.12) × 10 - 1 1 cm 3 molecule - 1 s - 1 , k s = (8.40 ′ 0.60) × 10 - 1 1 cm 3 molecule - 1 s - 1 . k t = (5.90 ′ 0.30) × 10 - 1 1 cm 3 molecule - 1 s - 1 , with f(-CH 2 -) = f(>CH 2 -) = f(>C<) = f = 0.85 ′ 0.06. Tests were carried out to investigate the potential interference from production of excited state HCl(v = 1) in the Cl + alkane reactions. There is some evidence for HCl(v = 1) production in the reaction of Cl with n-hexane.
A Fuzzy-Logic-Based Double Q -Learning Routing in Delay-Tolerant Networks

Delay-tolerant networks (DTNs) are wireless mobile networks, which suffer from frequent disruption, high latency, and lack of a complete path from source to destination. The intermittent connectivity in DTNs makes it difficult to efficiently deliver messages. Research results have shown that the routing protocol based on reinforcement learning can achieve a reasonable balance between routing performance and cost. However, due to the complexity, dynamics, and uncertainty of the characteristics of nodes in DTNs, providing a reliable multihop routing in DTNs is still a particular challenge. In this paper, we propose a Fuzzy-logic-based DoubleQ -Learning Routing (FDQLR) protocol that can learn the optimal route by combining fuzzy logic with the Double Q-Learning algorithm. In this protocol, a fuzzy dynamic reward mechanism is proposed, and it uses fuzzy logic to comprehensively evaluate the characteristics of nodes including node activity, contact interval, and movement speed. Furthermore, a hot zone drop mechanism and a drop mechanism are proposed, which can improve the efficiency of message forwarding and buffer management of the node. The simulation results show that the fuzzy logic can improve the performance of the FDQLR protocol in terms of delivery ratio, delivery delay, and overhead. In particular, compared with other related routing protocols of DTNs, the FDQLR protocol can achieve the highest delivery ratio and the lowest overhead.
Algorithmic Aspects of Some Variations of Clique Transversal and Clique Independent Sets on Graphs

This paper studies the maximum-clique independence problem and some variations of the clique transversal problem such as the {k}-clique, maximum-clique, minus clique, signed clique, and k-fold clique transversal problems from algorithmic aspects for k-trees, suns, planar graphs, doubly chordal graphs, clique perfect graphs, total graphs, split graphs, line graphs, and dually chordal graphs. We give equations to compute the {k}-clique, minus clique, signed clique, and k-fold clique transversal numbers for suns, and show that the {k}-clique transversal problem is polynomial-time solvable for graphs whose clique transversal numbers equal their clique independence numbers. We also show the relationship between the signed and generalization clique problems and present NP-completeness results for the considered problems on k-trees with unbounded k, planar graphs, doubly chordal graphs, total graphs, split graphs, line graphs, and dually chordal graphs.

PENETRATION OF UV‐B AND BIOLOGICALLY EFFECTIVE DOSE‐RATES IN NATURAL WATERS *

Abstract— Spectral irradiance measurements. from 310 to 650 nm. have been made in low and modcrately productive ocean waters. These new data and selected earlier clear ocean water data are used as a basis for extrapolating the diffuse attenuation coefficient for irradiance into the 280 nm region. This allows a quantitative calculation of the penetration of UV‐B (280–340 nm) and of biologically (DNA) effective dose‐rates as a function of depth into various ocean water types. The model of Green et al. (1974a) for various atmospheric ozone thicknesses has been used to obtain input surface irrddiancc for this calculation. Our purpose is to provide a basis for estimating the penetration of possible increased UV‐B into natural waters due to possible changes in the ozone concentration of the stratosphere. Given appropriate biological data, this method allows a quantitative evaluation of radiation effects on aquatic organisms as a function of depth. As a specific example, our results have been graphically compared with the dosage‐response results on anchovy larvae obtained by Hunter et al. (1978).
Tracing the Clouds. A research taxonomy of cloud-ERP in SMEs

Cloud computing is an enabler and accelerator of digital transformation, which has brought many advantages that only large companies had before for any start-up and small firm could benefit. Cloud-based computing in the form of SaaS (Software as a Service) has given rise to a revolutionary new way of delivering software applications via the Internet on a pay-per-use basis. Cloud-ERP (Enterprise Resource Planning) solutions have become more affordable, easier to implement, simpler to maintain, and thus especially suitable for small and medium-sized enterprises (SMEs), which have limited resources and may not be willing to invest in on-premise solutions. Employing this technology empowers integrated management of business processes and has the potential to add technical and strategic business value for small businesses. Given the claimed significance of SMEs in a structure of the world economy, we embarked on a detailed study of the existing published literature to determine the status quo of research on cloud-ERP technology in SMEs and how it has evolved in terms of quantity, content, and publication outlets. This is achieved by systematically reviewing 74 articles from 43 journals and 22 conferences published between 1 January 2010 and 30 June 2019. Using the ERP lifecycle-based framework by Esteves and Pastor (1999), articles are classified according to six life-cycle phases: adoption decision, acquisition, implementation, use and maintenance, evolution, and retirement. The findings, derived from a meta-analysis, illustrate that while current literature and studies related to the adoption decision phase are very rich, research on other phases of the ERP life cycle lacks strong empirical validation, due to a limited amount of publications. This study presents a comprehensive, structured literature review on cloud-based ERP adoption among SMEs and provides both academics Accepting editor: Eli Hustad 1 Yasiukovich and Haddara: Tracing the Clouds Published by AIS Electronic Library (AISeL), 2020 © Scandinavian Journal of Information Systems, 2020 32(2), 237-304 Yasiukovich & Haddara: Tracing the Clouds 238 and practitioners with a holistic view of the state of the current body of knowledge on the topic along with an understanding of how cloud-ERP in SMEs research is evolving.

Kinetics of chromium(III) oxidation to chromium(VI) by reaction with manganese dioxide

The kinetics of oxidation of aqueous Cr(III) to Cr(VI) by reaction with pyrolusite (.beta.-MnO/sub 2/(s)) were studied in aerated and deaerated solutions at 27/sup 0/C for pH 3.0-10.1, for 10/sup -4.7/-10/sup -3.4/ M Cr(III), and as a function of . beta. -MnO/sub 2/(s) surface area to assess the possible effects on Cr transport in industrial waste materials. The oxidation of aqueous Cr(III) is not appreciably affected by dissolved oxygen, indicating that Cr(III) reacts directly with . beta. -MnO/sub 2/(s) to produce Cr(VI) and not by catalyzed reactions with oxygen at the . beta. -MnO/sub 2/(s) surface. In acidic solutions, the oxidation of aqueous Cr(III) is highly nonlinear with time, possibly because strong adsorption of the produced anionic Cr(VI) species limits the amount of Cr(III) species able to contact active oxidizing sites on the . beta. -MnO/sub 2/(s) surface. The following expression is derived from the rate data for pH 3.0-4.7 that empirically account for the nonlinear rate by describing the reaction rate in terms of the fraction of Cr(VI) to total Cr, f/sub Cr/, remaining in solution: df/sub Cr/dt (s/sup -1/) = k(AV)(Cr/sub t/)/sup -1/(1.0 - f/sub Cr/)/sup 3.2 (+/- 0.8) for f/sub Cr/ less than or equal to 1.0 where k = 2.0 (+- 1.6) x 10/supmore » -3/ mol x m/sup -2/ x s/sup -1/, AV is the . beta. -MnO/sub 2/(s) surface area to solution volume ratio in m/sup 2/ x L/sup -1/, and (Cr/sub t/) is the molar concentration of total dissolved Cr. In slightly acidic to basic solutions, the oxidation of aqueous Cr(III) is very slow and is limited by the low solubility of Cr(OH)/sub 3/(s). 19 references, 6 figures, 4 tables. « less
Effects of ferromagnet–molecule chemical bonding on spin injection in an Fe3O4–molecule granular system

Spin injection at the interface of Fe3O4/stearic acid molecule is investigated in a comparative study of Fe3O4 nanoparticles chemically bonded with molecules (ChemNPs) and Fe3O4 nanoparticles with physically absorbed molecules (PhyNPs). The resistance of PhyNPs is two orders of magnitude larger than that of ChemNPs, indicating that the resistance of PhyNPs is dominated by the energy barrier at the Fe3O4–molecule interface. A magnetoresistance of −12% under a field of 5.8 kOe at room temperature is observed in ChemNPs, in sharp contrast to the zero magnetoresistance in PhyNPs, reflecting that the chemical bonding is crucial for spin injection. We attribute this result to the induced magnetic moment in molecules by proximity effect, which is likely the origin of the spin-dependent tunnelling through molecules. In addition, the estimated relatively large spin polarization of ChemNPs suggests electronic hybridization at the interface and improved oxygen stoichiometry of the Fe3O4 surface.
Theme park experience: Factors explaining amount of pleasure from a theme park visit, time allocation for theme park activities, perceived value, queuing quality, satisfaction, and loyalty

A considerable amount of literature describes concepts that predict theme park visitor behavior. Although previous studies made an effort to measure the impact of several variables on theme park visitors’ loyalty, there is a lack of empirical attention on the impact of some consumption variables such as previous experience, perceived queuing quality, waiting time, using of virtual queuing, and the role of anticipating and remembering the visit. The current study introduces several new experience concepts that were not previously discussed in the literature: the amount of pleasure from anticipation, visiting, and remembering the experience, and time allocation for waiting in lines, amusement activities, and food consumption. Factors that explain these variables, as well as factors that explain perceived value, queuing quality, satisfaction, and loyalty were investigated through survey data from a cross-sectional study. The results demonstrate that previous theme park experience has significant influence on customer loyalty, and explains the amount of pleasure visitors receive from anticipation, remembering, and the actual visiting experience. Another important finding is related to the role of virtual queuing, which has relationships with perceived value, perceived waiting time, perceived queuing quality, satisfaction, loyalty, as well as the amount of pleasure from anticipation, visiting, and remembering the theme park visit. Theoretical and managerial implications and future research directions are discussed.

Predicting the toxicity of metal‐spiked laboratory sediments using acid‐volatile sulfide and interstitial water normalizations

Numerous studies have shown that dry weight concentrations of metals in sediments cannot be used to predict toxicity across sediments. However, several studies using sediments from both freshwater and saltwater have shown that interstitial water concentration or normalizations involving acid-volatile sulfide (AVS) can be used to predict toxicity in sediments contaminated with cadmium, copper, nickel, lead, or zinc across a wide range of sediment types. Six separate experiments were conducted in which two or three sediments of varying AVS concentration were spiked with a series of concentrations of cadmium, copper, lead, nickel, or zinc or a mixture of four of these metals. The amphipod Ampelisca abdita was then exposed to the sediments in 10-d toxicity tests. Amphipod mortality was sediment dependent when plotted against dry weight metals concentration but was not sediment dependent when plotted against simultaneously extracted metal (SEM)/AVS or interstitial water toxic units (IWTUs). Sediments with SEM/AVS ratios 1.0 were frequently (80%) toxic. Similarly, sediments with 0.5 IWTU were toxic 94.4% of the time. These results, coupled with results from related studies, demonstrate that an understanding of the fundamental chemical reactions which control the availability of cadmium, copper, lead, nickel, and zinc in sediments can be used to explain observed biological responses. We believe that using SEM/AVS ratios and IWTUs allows for more accurate predictions of acute mortality, with better causal linkage to metal concentration, than is possible with sediment evaluation tools which rely on dry weight metal concentrations.
Trust in Courier Services as a Determinant of Service Quality

The article aims to examine relationships between five constructs: the usefulness of courier services (U), the ease of use of courier services (EU), the trust in courier services (T), the service quality (SQ), and the future intention to use courier services (FI). The research focuses on courier services. An electronic questionnaire was used to conduct confidential interviews. It was distributed between January and March 2019. The number of questionnaires returned by courier service customers amounted to 1073. The authors used Generalized Least Squares (GLS) of Structural Equation Modelling (GLS-SEM) to verify the hypotheses. AMOS software was set to test the hypothesised relationships. The obtained results confirmed statistically significant relationships between the variables of the ease of use and the trust in service, the usefulness and the trust in service, the trust in service and the service quality and, finally, the service quality and the future intention to use the services. The obtained results confirmed an important role of technological aspects in courier service quality, which will become the main determinant of the development of this sector in the future. The authors proposed a new approach to the definition of trust in service. Apart from the interpersonal trust, they shed more light on the trust in the supplier, i.e. the trust in the used technologies.
Aqueous Gel Permeation Chromatographic Methods for Technical Lignins

Abstract The molecular weights and molecular weight distributions of lignosulfonates and soda lignins were determined by aqueous gel permeation chromatography (GPC). The elution behavior of the samples, was investigated in detail to evaluate the non-size-exclusive effect in the aqueous GPC system. The ionic strength and pH are thought to be the main factors influencing the accuracy and the reliability of measurements. Solutions of 0.1M NaNO3 with pH 7 or 0.1 M NaNO3 with pH 12 were shown to be optimum for determining the molecular weight of lignosulfonate and alkali lignin. Accuracy of the method was checked by comparing the data obtained by aqueous GPC with that from vapor pressure osmometry (VPO).
Methane Oxidation in a Neutral Landfill Cover Soil: Influence of Moisture Content, Temperature, and Nitrogen-Turnover

Well-managed, aerated cover soils can have a mitigating effect on methane emission from landfills. The influence of moisture content, soil temperature, and N on the methane uptake capacity of a neutral landfill cover soil was examined. A soil moisture content of 15% w/w gave the maximum CH{sub 4} oxidation rate (2.36 ng CH{sub 4}{sup -1}g{sup -1} soil). When wetter, CH{sub 4} consumption was slower (e.g., 1.6 ng CH{sub 4} h{sup -1} g {sup -1} at 30% w/w) because of a limited gas diffusion. At lower soil moisture, microbial activity was reduced and consequently the oxidation capacity decreased (e.g., 0.84 ng CH{sub 4} {sup -1} g{sup -1} at 5% w/w). Optimum temperature was between 25 and 30{degrees}C. The calculated activation energy of the CH{sub 4} oxidation was 56.5 kj K{sup -1} mol{sup -1}. After NH4{sub 4}{sup +} addition, a negative linear correlation was found between the methane oxidation rate and the nitrous oxide flux (R{sup 2} = 0.96 Y1 = 2.7 - 0.44 x Y2). Addition of NO{sub 3}{sup -} had no significant effect on CH{sub 4} oxidation. The effect of organic residue amendments depended on their C/N ratios. Crop residues with a high C/N ratio (wheat [Triticum sativum L.] andmore » maize [Zea mays L.] straw) stimulated N-immobilization and did not affect the methane-oxidizing capacity. On the other hand, addition of crop residues with low C/N ratios (potato [Solanum tuberosum L.] and sugar beet [Beta vulgaris cv. Altissima] leaves) stimulated N-mineralization, resulting in a strong inhibition of the methane oxidation. 38 refs., 4 figs., 2 tabs. « less
50th Annual Meeting of the Association for European Paediatric and Congenital Cardiology, Rome, Italy, June 1–4, 2016

Background: Both abnormal lengthening and shortening of the corrected QT interval (QTc) on the electrocardiogram indicating substantial disturbance of autonomic function in epilepsy have been reported. Aim: We hypothesized that children with epilepsy and abnormal EEG comparative to healthy children may have ECG abnormalities in the corrected QT ( QTc ) interval that can indicate chanellopathy disturbances in the re-polarization period that is more pronounced during acceleration of heart rate. Methods: Rest ECG and Holter ECG were done for 75 children that were devised into three groups: Group I: 25 children with epilepsy and normal EEG. Group II: 25 children with Epilepsy and abnormal EEG. Group III: 25 healthy children. ECG data from healthy children, children with epilepsy and normal electroencephalogram (EEG), and children with epilepsy and abnormal EEG were prospectively reviewed in rest ECG and during maximal heart rate in acceleration of rhythm in Holter ECG traces. Corrected QT interval (QTc), and QTC dispersion were assessed in 25 healthy children, 25 children with epilepsy and normal EEG, and 25 children with epilepsy and abnormal EEG. Results: In children with epilepsy and normal EEG the mean QTc was 0.426 mesc, and the mean QTc dispersion was 0.076mesc. In the group of children with epilepsy and abnormal EEG the QTc 0.448 was and QTc dispersion was 0.152. In the healthy children, the control group, mean QTc was 0.372mesc, and the mean QTc dispersion was 0.003mesc. Conclusion:Our data suggest a significant substantial disturbance of autonomic function in patients with epilepsy. QTc and QTc dispersion were found to be significantly prolonged in children with epilepsy, especially in patients with abnormal EEG.
