Odonata as bioindicator for monitoring anthropogenic disturbance of Owabi wetland sanctuary, Ghana

Abstract This study proposes a method for assessing anthropogenic disturbance in the Owabi wetland sanctuary in Ghana using Odonata. Uniqueness of a species to specific land use (LU) class and its tolerance to environmental conditions served as the criteria for the monitoring. Twenty-nine species were identified from the families Aeshnidae, Libellulidae, Chlorocyphidae, Calopterygidae and Coenagrionidae. A Kruskal-Wallis’s test suggest significant difference in species richness across the anthropogenic disturbance regimes. Pantala flavescens (Fabricius, 1798) was identified as an indicator of high anthropogenic disturbance; Orthetrum abbotti Calvert, 1892 and Africallagma vaginale (Sjöstedt, 1917) were indicators of moderate anthropogenic disturbance; and Gynacantha bullata Karsch, 1891, Tramea limbata (Desjardins, 1832), Olpogastra lugubris Karsch, 1895, Neodythemis klingi (Karsch, 1890), Brachythemis leucosticta (Burmeister, 1839), Chlorocypha curta (Hagen in Sélys, 1853), Chlorocypha luminosa (Karsch, 1893), Chlorocypha radix Longfield, 1959 and Agriocnemis sp. were identified as indicators of low anthropogenic disturbance.
Field Cancellation for Circuits Encircled by VHF Wireless Power Transfer Coils

Components and circuits encircled by wireless power transfer coils allow miniaturization but require field cancellation for components and circuits that are sensitive to the magnetic field. Very high frequency operation reduces the volume and number of components, which makes encirclement within WPT coils easier. A field cancellation method is investigated to minimize the magnetic field for the encircled circuits in WPT coils using a two-coil structure toward the best cancellation performance, practical construction, and minimum cost. The WPT and canceling coils are driven together by a single current-mode class D power converter with opposite-phase currents to optimize the field cancellation within the coils. Using this cancellation method, the magnetic field for the encircled circuits was reduced by 99% in hardware compared to that without cancellation.
Identification and Characterization of Jasmonic Acid Biosynthetic Genes in Salvia miltiorrhiza Bunge

Jasmonic acid (JA) is a vital plant hormone that performs a variety of critical functions for plants. Salvia miltiorrhiza Bunge (S. miltiorrhiza), also known as Danshen, is a renowned traditional Chinese medicinal herb. However, no thorough and systematic analysis of JA biosynthesis genes in S. miltiorrhiza exists. Through genome-wide prediction and molecular cloning, 23 candidate genes related to JA biosynthesis were identified in S. miltiorrhiza. These genes belong to four families that encode lipoxygenase (LOX), allene oxide synthase (AOS), allene oxide cyclase (AOC), and 12-OPDA reductase3 (OPR3). It was discovered that the candidate genes for JA synthesis of S. miltiorrhiza were distinct and conserved, in contrast to related genes in other plants, by evaluating their genetic structures, protein characteristics, and phylogenetic trees. These genes displayed tissue-specific expression patterns concerning to methyl jasmonate (MeJA) and wound tests. Overall, the results of this study provide valuable information for elucidating the JA biosynthesis pathway in S. miltiorrhiza by comprehensive and methodical examination.
High-Precision Real-Time Detection of Blast Furnace Stockline Based on High-Dimensional Spatial Characteristics

The real-time, continuity, and accuracy of blast furnace stockline information are of great significance in reducing energy consumption and improving smelting efficiency. However, the traditional mechanical measurement method has the problem of measuring point discontinuity, while the radar measurement method exhibits problems such as weak anti-interference ability, low accuracy, and poor stability. Therefore, a high-dimensional, spatial feature stockline detection method based on the maximum likelihood radial basis function model (MLRBFM) and structural dynamic self-optimization RBF neural network (SDSO-RBFNN) is proposed. Firstly, the discrete time series joint partition method is used to extract the time dimension periodic features of the blast furnace stockline. Based on MLRBFM, the high-dimensional spatial features of the stockline are then obtained. Finally, an SDSO-RBFNN is constructed based on an eigen orthogonal matrix and a right triangular matrix decomposition (QR) direct clustering algorithm with spatial–temporal features as input, so as to obtain continuous, high-precision stockline information. Both the simulation results and industrial validation indicate that the proposed method can provide real-time and accurate stockline information, and has great practical value for industrial production.

HOsT: Towards a Low-Cost Fog Solution via Smart Objects to Deal with the Heterogeneity of Data in a Residential Environment

With the fast and unstoppable development of technology, the amount of available technological devices and the data they produce is overwhelming. In analyzing the context of a smart home, a diverse group of intelligent devices generating constant reports of its environment information is needed for the proper control of the house. Due to this demand, many possible solutions have been developed in the literature to assess the need for processing power and storage capacity. This work proposes HOsT (home-context-aware fog-computing solution)—a solution that addresses the problems of data heterogeneity and the interoperability of smart objects in the context of a smart home. HOsT was modeled to compose a set of intelligent objects to form a computational infrastructure in fog. A publish/subscribe communication module was implemented to abstract the details of communication between objects to disseminate heterogeneous information. A performance evaluation was carried out to validate HOsT. The results show evidence of efficiency in the communication infrastructure; and in the impact of HOsT compared with a cloud infrastructure. Furthermore, HOsT provides scalability about the number of devices acting simultaneously and demonstrates its ability to work with different devices.

Restoration of overhead distribution networks by means of temporary fault indicators application

This paper discusses a new methodology for restoration of overhead distribution networks based on the application of temporary fault indicators. Unlike the traditional fault indicators, these are installed on the network only after the occurrence of the fault. Placed in key points of the network after the disconnection of a feeder, for example, the temporary fault indicators can sense the fault current after the first manual reclosing attempt. Then, they send this information to a portable operation unit that helps to pinpoint the faulty branch of the network by showing the fault ́s path in a map. All the devices communicate in a ZigBee mesh network and the fault indicators are georeferenced by GPS, which give their location in the network map.

In this letter, a compact ultrawideband (UWB) multi‐input‐multi‐output (MIMO) antenna with cross‐shaped unconnected Ground stub using characteristic mode analysis (CMA) is presented. The proposed work consists of two elliptical shape monopole UWB antenna with a cross‐shaped stub in the ground plane. The compact MIMO antenna has the dimension of 25 × 25 × 1.6 mm3. These monopoles are able to excite several characteristic modes (CMs), which support to wideband resonance, and cross‐shaped stub support CM at lower frequency band in the ground plane and reduces mutual coupling between monopoles. The UWB MIMO antenna is resonating in frequency bands from 2.97 to 13.8 GHz bandwidth with a good mutual coupling (<−15 dB). The diversity performance envelop correlation coefficient (ECC) and diversity gain (DG) of the antenna are less than 0.05 and more than 9.97, respectively. The experimental result confirming a good treaty with the simulated ones, so that the proposed antenna is suitable for compact UWB MIMO applications.
Synthesis and Biological Activity Investigation of New Oxazolopyrimidoazepine Derivatives: Application of Ag/Fe3O4/TiO2/CuO@MWCNTs MNCs in the Reduction of Organic Pollutants

Abstract Ag/Fe3O4/TiO2/CuO@MWCNTs magnetic nanocomposites were synthesized by the Petasites hybridus rhizome water extract as green media and used for one-pot multicomponent reaction of isatins, electron deficient acetylenic compounds, α-haloketones, ammonium acetate, tert-butyl isocyanide and ethyl bromopyruvate in aqueous media at room temperature for the production of novel derivatives of oxazolopyrimidoazepines in excellent yields. The synthesized oxazolopyrimidoazepines have OH and NH functional groups that have acidic hydrogen and show high antioxidant activity. Moreover, reduction of organic pollutants such 4-nitrophenol (4-NP) was performed by synthesized Ag/Fe3O4/TiO2/CuO@MWCNTs in water at room temperature. The outcomes showed this catalyst was decreased organic pollutants in few seconds. The employed process for the production of oxazolopyrimidoazepines has some benefits such as short time of reactions, excellent efficiency of product, easy separation of catalyst and products. HIGHLIGHTS Green chemistry is the use of a set of principles to reduce or eliminate the use or generation of unsafe materials in the design, fabrication and applications of chemical products. Among solvents, water is a green solvents and very suitable for performing organic reaction. The present procedure avoids the use of toxic solvent. Some representatives of this class of azaheterocycles are known as antiviral agents, glycosidase inhibitors, anticancer agents or antidiabetics. Therefore, in view of their medicinal relevance, an increasing number of synthetic methods have been described in recent years for the construction of highly substituted azepine derivatives.
Research on Control Strategy Based on Second-order Linear Active Disturbance Rejection Control for LCL-type Grid-connected Inverter

The grid-connected system is characterized by nonlinearity, strong coupling and uncertainty, and the current output from the grid-connected inverter has a large number of harmonics and cannot be directly connected to the grid. Therefore, usually, LCL filter is added between grid-connected inverter and power grid, but there is resonance problem in LCL filter. The self-anti-disturbance strategy predicts and compensates the uncertain factors affecting system control as accumulated disturbances, and can modify the original system to an integral series type to obtain the desired control performance. Therefore, based on the mathematical model of LCL filter, the second order linear active disturbance rejection control (LADRC) is designed, and its tracking ability and anti-interference ability are analyzed. Finally, The simulation results verify the adopted strategy.
Cohomologies of Reynolds operators on n-Lie algebras

Abstract In this paper, first we introduce the notion of a Reynolds operator on an n-Lie algebra and illustrate the relationship between Reynolds operators and derivations on an n-Lie algebra. We give the cohomology theory of Reynolds operators on an n-Lie algebra and study infinitesimal deformations of Reynolds operators using the second cohomology group. Then we introduce the notion of NS-n-Lie algebras, which are generalizations of both n-Lie algebras and n-pre-Lie algebras. We show that an NS-n-Lie algebra gives rise to an n-Lie algebra together with a representation on itself. Reynolds operators and Nijenhuis operators on an n-Lie algebra naturally induce NS-n-Lie algebra structures. Finally, we construct Reynolds -Lie algebras and Reynolds 3-Lie algebras from Reynolds n-Lie algebras and Reynolds commutative associative algebras respectively.
Mechanical Disturbance of Osteoclasts Induces ATP Release That Leads to Protein Synthesis in Skeletal Muscle through an Akt-mTOR Signaling Pathway

Muscle and bone are tightly integrated through mechanical and biochemical signals. Osteoclasts are cells mostly related to pathological bone loss; however, they also start physiological bone remodeling. Therefore, osteoclast signals released during bone remodeling could improve both bone and skeletal muscle mass. Extracellular ATP is an autocrine/paracrine signaling molecule released by bone and muscle cells. Then, in the present work, it was hypothesized that ATP is a paracrine mediator released by osteoclasts and leads to skeletal muscle protein synthesis. RAW264.7-derived osteoclasts were co-cultured in Transwell® chambers with flexor digitorum brevis (FDB) muscle isolated from adult BalbC mice. The osteoclasts at the upper chamber were mechanically stimulated by controlled culture medium perturbation, resulting in a two-fold increase in protein synthesis in FDB muscle at the lower chamber. Osteoclasts released ATP to the extracellular medium in response to mechanical stimulation, proportional to the magnitude of the stimulus and partly dependent on the P2X7 receptor. On the other hand, exogenous ATP promoted Akt phosphorylation (S473) in isolated FDB muscle in a time- and concentration-dependent manner. ATP also induced phosphorylation of proteins downstream Akt: mTOR (S2448), p70S6K (T389) and 4E-BP1 (T37/46). Exogenous ATP increased the protein synthesis rate in FDB muscle 2.2-fold; this effect was blocked by Suramin (general P2X/P2Y antagonist), LY294002 (phosphatidylinositol 3 kinase inhibitor) and Rapamycin (mTOR inhibitor). These blockers, as well as apyrase (ATP metabolizing enzyme), also abolished the induction of FDB protein synthesis evoked by mechanical stimulation of osteoclasts in the co-culture model. Therefore, the present findings suggest that mechanically stimulated osteoclasts release ATP, leading to protein synthesis in isolated FDB muscle, by activating the P2-PI3K-Akt-mTOR pathway. These results open a new area for research and clinical interest in bone-to-muscle crosstalk in adaptive processes related to muscle use/disuse or in musculoskeletal pathologies.

Are You Happy? A Validation Study of a Tool Measuring Happiness

This study aims at evaluating the psychometric properties of a new scale to measure experienced happiness—the Measure of Happiness (MH)—in a nonclinical sample composed of Italian adults from the general population. The MH was developed not only to provide a global measure of happiness, but also and more importantly to identify the specific areas of the individual’s life that are related to the experienced happiness. A total of 787 adults filled the MH and other self-report questionnaires, in order to assess the factor structure, reliability and external validity of the measure. The factorial analysis identified the following five dimensions: Psychophysics Status, Financial Status, Relational Private Sphere, Socio-Relational Sphere, and Life Perspective. The scale so defined was administered to a second independent group of 421 participants for the (multigroup) confirmatory factor analysis (CFA). A multigroup factor analysis based on gender confirmed the MH structure. The convergent validity of the MH was assessed by comparing the MH scores with a previously validated test of happiness and quality of life, as well as with dispositional constructs with which happiness is known to be negatively correlated, namely, anxiety and depression. The MH showed satisfactory psychometric properties and a strong significant positive relationship between the two measures of happiness, and a substantial negative association with the measures of anxiety and depression, supporting the validity of the MH to assess the construct of experienced happiness. The implications and possible applications of the MH are then discussed.
Integrative Metabolome and Transcriptome Analysis Reveals the Regulatory Network of Flavonoid Biosynthesis in Response to MeJA in Camellia vietnamensis Huang

Flavonoids are secondary metabolites widely found in plants, which perform various biological activities, such as antiinflammation, antioxidation, antitumor, and so on. Camellia vietnamensis Huang, a species of oil-tea Camellia tree, is an important woody oil crop species widely planted on Hainan Island, which provides health benefits with its high antioxidant activity and abundant flavonoid content. However, very little is known about the overall molecular mechanism of flavonoid biosynthesis in C. vietnamensis Huang. In this study, methyl jasmonate (MeJA) is used as an inducer to change the content of secondary metabolites in C. vietnamensis. Then, the potential mechanisms of flavonoid biosynthesis in C. vietnamensis leaves in response to MeJA were analyzed by metabolomics and transcriptomics (RNA sequencing). The results showed that metabolome analysis detected 104 flavonoids and 74 fatty acyls which showed different expression patterns (increased or decreased expression). It was discovered by KEGG analysis that three differentially accumulated metabolites (cinnamaldehyde, kaempferol and quercitrin) were annotated in the phenylpropanoid biosynthesis (ko00940), flavonoid biosynthesis (ko00941), and flavone and flavonol biosynthesis (ko00944) pathways. In the transcriptome analysis, 35 different genes involved in the synthesis of flavonoids were identified by MapMan analysis. The key genes (PAL, 4CL, CCR, CHI, CHS, C4H, FLS) that might be involved in the formation of flavonoid were highly expressed after 2 h of MeJA treatment. This study provides new insights and data supporting the molecular mechanism underlying the metabolism and synthesis of flavonoids in C. vietnamensis under MeJA treatment.
Dbf4-Cdc7 (DDK) Inhibitor PHA-767491 Displays Potent Anti-Proliferative Effects via Crosstalk with the CDK2-RB-E2F Pathway

Precise regulation of DNA replication complex assembly requires cyclin-dependent kinase (CDK) and Dbf4-dependent kinase (DDK) activities to activate the replicative helicase complex and initiate DNA replication. Chemical probes have been essential in the molecular analysis of DDK-mediated regulation of MCM2-7 activation and the initiation phase of DNA replication. Here, the inhibitory activity of two distinct DDK inhibitor chemotypes, PHA-767491 and XL-413, were assessed in cell-free and cell-based proliferation assays. PHA-767491 and XL-413 show distinct effects at the level of cellular proliferation, initiation of DNA replication and replisome activity. XL-413 and PHA-767491 both reduce DDK-specific phosphorylation of MCM2 but show differential potency in prevention of S-phase entry. DNA combing and DNA replication assays show that PHA-767491 is a potent inhibitor of the initiation phase of DNA replication but XL413 has weak activity. Importantly, PHA-767491 decreased E2F-mediated transcription of the G1/S regulators cyclin A2, cyclin E1 and cyclin E2, and this effect was independent of CDK9 inhibition. Significantly, the enhanced inhibitory profile of PHA-767491 is mediated by potent inhibition of both DDK and the CDK2-Rb-E2F transcriptional network, that provides the molecular basis for its increased anti-proliferative effects in RB+ cancer cell lines.
SWEmean of Quadriceps, a Potential Index of Complication Evaluation to Patients with Chronic Obstructive Pulmonary Disease

Purpose To develop a potential quadriceps’ index of complication evaluation for patients with chronic obstructive pulmonary disease (COPD) which is simple, convenient, and quantifiable. Patients and Methods We conducted a prospective study of 59 patients with COPD and 56 healthy controls recruited by the Chengdu First People’s Hospital. Grayscale ultrasound (US) of the rectus femoris was performed to measure thickness (RFthick) and cross-sectional area (RFcsa). Shear wave elastography was used to determine the mean elasticity index (SWEmean) of the rectus femoris (SWERFmean), vastus lateralis (SWEVLmean) and vastus medialis (SWEVMmean). Clinical features included dyspnea index score (modified British Medical Research Council (MMRC) score), COPD Assessment Test (CAT), the Five-Repetition Sit-to-Stand Test (5STS) and the Six-Minute Walk Test (6MWT). We compared the differences between US parameters and SWEmean in healthy controls and COPD patients. We also described the correlation between US parameters, SWEmean and clinical features of patients with COPD. Results The intra-observer repeatability for the performance of using SWE to measure quadriceps stiffness was excellent (intraclass correlation coefficient (ICC)>0.75, p < 0.001). There was a statistically significant difference in the SWEmean of the quadriceps (p < 0.001), but no significant difference in terms of RFthic and RFcsa (p > 0.05) between healthy controls and COPD patients. The SWERFmean was positively correlated with the 6MWT (r = 0.959, p < 0.001), and negatively related to the mMRC (r=−0.825, p < 0.001), CAT (r=−0.993, p < 0.001) and 5STS (r=−0.936, p < 0.001). However, the RFthic, RFcsa, SWEVLmean and SWEVMmean were not correlated with clinical features (p > 0.05). Conclusion As a supplement to US, SWE reflects changes of stiffness in the quadriceps of COPD patients, and can expanding the dimension of US for assessing the quadriceps. Furthermore, SWEmean was associated with clinical features, and represents a potential index with which to reflect the clinical features of COPD patients.
