The percentage of completeness in cycle 2 was 96.88% with an average of 88.13. Student learning activities also showed a significant increase in each indicator.
Synthesis, Structural Determination, and Antioxidant Activities of Acyclic and Substituted Heterocyclic Phosphonates Linearly Linked 4-hydroxy-2(1H)-quinolinone

The chemical reactivity of 3-[(E)-3-(dimethylamino)-2-propenoyl]-4-hydroxy-1-methy-2(1H)-quinolinone (1) towards some phosphorus reagents was studied. The enaminone 1 was cyclized into pyranoquinolinylphosphonate 2 via treatment with diethyl phosphite in basic medium. However, its reaction with triethoxy phosphonoacetate gave the substituted oxopyranylphosphonate 3. Using the same reaction conditions, both thioxopyridinylphosphonate 4 and oxopyranylphosphonate 5 were produced via a reaction of enaminone 1 with both diethyl 2-amino-2-thioxoethylphosphonate and diethyl vinylphosphonate, respectively, in low yields. In addition, the two novel oxopyridinylphosphonates 6 and 7 were obtained by treatment of enaminone 1 with a diethyl cyanomethylphosphonate reagent. Two oaxathiaphosphininyl derivatives, 8 and 9, were obtained by treatment of the enaminone 1 with O, O-diethyl dithiophosphoric acid under different reaction conditions. Diazaphosphininyl 11 and oxazaphosphininyl 12 derivatives were obtained in excellent yields using a P-phenylphosphonic diamide reagent under different reaction conditions. The treatment of the enaminone 1 with phosphorus pentasulfide produced the non-phosphorylated product thioxothiopyranoquinolinone 13. Finally, the enaminone was turned into oxathiaphosphininyl 14 using Lawesson’s reagent. The possible reaction mechanisms of the formation of these products were discussed. The structures of newly isolated products were established by elemental analysis and spectral tools. The compounds were evaluated for their antioxidant activities.

Audit and CSR committees: are they complements or substitutes in CSR reporting, assurance and GRI framework adoption?

Purpose This study aims mainly to test the effect of audit committee independence and expertise attributes on corporate social responsibility (CSR) reporting, assurance and global reporting initiative (GRI) framework adoption and to investigate how CSR committee existence moderates this main relationship. Design/methodology/approach The study uses a large global sample that includes all (59,172) firm-year observations having CSR-related data in the Thomson Reuters Eikon database for a period between 2002 and 2019. The empirical analyses are based on random-effects logistic panel regression and Hayes methodology for the moderation analysis. Findings The study finds that audit committee independence and expertise are significantly associated with CSR reporting, CSR report assurance and GRI framework adoption. Moderation analysis largely supports the existence of a substitution role between audit and CSR committees and implies that audit committees are significant predictors of CSR reporting, assurance and GRI framework adoption mostly in the absence of the CSR committee. Practical implications The findings propose audit committee members be extra-vigilant in CSR reporting and assurance practices arising from undertaking substitution roles with the CSR committee. Hence, firms may configure their corporate structure in line with the results such as augmenting the audit committee with independent and expert members if they do not constitute a CSR committee. If firms establish a CSR committee, audit committee members may allocate less time to CSR reporting and assurance and more time to financial reporting quality. Originality/value This is the first study, to the best of the authors’ knowledge, to investigate the direct and indirect effect of audit committees’ attributes not only on CSR disclosure but also on GRI implementation and CSR reporting external assurance, considering the CSR committee’s possible substitutability or complementarity moderating role. This research develops a deeper understanding of audit committees’ non-financial role.
Three New Glycosides From the Stems of Derris elliptica

Three new glycosides, derriacuminosides A-C (1-3), were isolated from the stems of Derris elliptica (Wall.) Benth. Their chemical structures were determined by interpretations of HRESIMS and NMR spectra. The anti-inflammatory activity of compounds 1-3 were evaluated by inhibiting NO production in LPS activated RAW264.7 cells. Compounds 1-3 potentially inhibited NO production with IC50 values of 26.54 ± 3.08, 26.35 ± 1.37, and 49.71 ± 2.93 µM, respectively, compared to the positive control, L-NMMA (IC50 35.56 ± 2.98 µM).
A visual understanding of electrical transformations and generalized abc to αβ0 and dq0 transformation

Varied control applications in electrical engineering find the utility of the theory of transformation of three‐phase quantities from abc to αβ0 and dq0 reference frames. These transformations are vital in simplifying the control equations and their implementation. However, for different applications, different orientations of the abc ‐, αβ ‐, and dq ‐axes are used. This results in a different transformation matrix for each such orientation. In this paper, a generalized abc to αβ0 and dq0 transformation matrix is proposed which can be utilized for any possible orientation and thus effectuates faster derivation of the transformation matrix. This is achieved by defining two parameters l and m whose values are obtained by observing the orientation of the axes. The transformation equation can therefore be obtained without having to undergo the steps of resolving abc quantities into their components along the αβ ‐ or dq ‐axes. Furthermore, this paper discusses the visual understanding of transformed electrical quantities. It is shown that the complex plots of real versus imaginary parts of instantaneous positive and negative symmetrical components have shapes which exhibit specific characteristics of electrical quantities and give a direct understanding about unbalance and presence of harmonics in the system.
Fundamental solutions of MHD Stokes flow

A simple analytical solution is obtained for the MHD stokeslet in a homogeneous magnetic field. This solution represents the flow past a small particle and can also be interpreted as the flow sufficiently far away from a body of finite size. Fundamental solutions are found in terms of velocity, pressure and scalar potential distributions for the flows due to either a concentrated force or a current source. The former consists of two basic solutions for the force parallel and transverse to the magnetic field, respectively. All fundamental solutions have the characteristic length scale of the Hartmann boundary layer and two parabolic wakes developing along the magnetic field.
Entanglement in the steady state of a collective-angular-momentum (Dicke) model

We model the behavior of an ion trap with all ions driven simultaneously and coupled collectively to a heat bath. The equations for this system are similar to the irreversible dynamics of a collective angular momentum system known as the Dicke model. We show how the steady state of the ion trap as a dissipative many-body system driven far from equilibrium can exhibit quantum entanglement. We calculate the entanglement of this steady state for two ions in the trap and in the case of more than two ions we calculate the entanglement between two ions by tracing over all the other ions. The entanglement in the steady state is a maximum for the parameter values corresponding roughly to a bifurcation of a fixed point in the corresponding semiclassical dynamics. We conjecture that this is a general mechanism for entanglement creation in driven dissipative quantum systems.
Multi-bump ground states of the fractional Gierer-Meinhardt system in $\mathbb{R}$

In this paper we study ground-states of the fractional Gierer-Meinhardt system on the line, namely the solutions of the problem \begin{equation*} \left\{\begin{array}{ll} (-\Delta)^su+u-\frac{u^2}{v}=0,\quad &\mathrm{in}~\mathbb{R},\\ (-\Delta)^sv+\varepsilon^{2s}v-u^2=0,\quad &\mathrm{in}~\mathbb{R},\\ u,v>0,\quad u,v\rightarrow0~&\mathrm{as}~|x|\rightarrow+\infty. \end{array}\right. \end{equation*} We prove that given any positive integer $k,$ there exists a solution to this problem for $s\in[\frac12,1)$ exhibiting exactly $k$ bumps in its $u-$component, separated from each other at a distance $O(\varepsilon^{\frac{1-2s}{4s}})$ for $s\in(\frac12,1)$ and $O(|\log\varepsilon|^{\frac12})$ for $s=\frac12$ respectively, whenever $\varepsilon$ is sufficiently small. These bumps resemble the shape of the unique solution of \begin{equation*} (-\Delta)^sU+U-U^2=0,\quad 0
Burst Automaton: Framework for Speed-Independent Synthesis Using Burst-Mode Specifications

Burst-mode (BM) formalism is a variant of an asynchronous finite-state machine (FSM) that operates in “BM” timing assumption and offers simple entry into the asynchronous circuit design. However, some of BM’s well-formedness properties, while useful for implementing BM specifications as circuits, are rather restrictive in some important contexts, e.g., BM’s maximal set property (or its analog, extended BM (XBM) formalism’s distinguishability constraint) forbids nondeterministic specifications that are inherent in some design approaches, input and output bursts must alternate meaning BMs are not a proper extension of FSMs with arcs labeled by single events, and BMs cannot express input-output concurrency whereas FSMs can with interleaving. The latter limitation is particularly problematic when interoperability between several formalisms is desirable. In this article, we propose the burst automation (BA) model that is more powerful and yet simpler than BM, by relaxing BM’s well-formedness properties. BA is a proper extension of FSMs, and can express input-output concurrency and nondeterminism. We define BA’s interleaving semantics via its asynchronous reachability graph that is an FSM, and develop three translations from BAs to signal transition graphs (STGs) that preserve strong bisimulation, weak bisimulation, or the language. Former two translations may be exponential, whereas the latter translation is linear. The resulting STG can then be used for verification and synthesis into speed-independent (SI) or quasi-delay-insensitive (QDI) circuits, or for composition with other STGs. The proposed workflow was implemented in Workcraft, and experimental results show an improved synthesis rate and a significant reduction in the literal count.

Association Between Hemoglobin Levels and Osteoporosis in Chinese Patients with Type 2 Diabetes Mellitus: A Cross-Sectional Study

Purpose To explore the relationship between hemoglobin levels and osteoporosis and the risk factors for osteoporosis in patients with type 2 diabetes mellitus (T2DM). Patients and methods A cross-sectional study was conducted in 495 T2DM adults. Medical data were collected from electronic medical records. Results T2DM patients with osteoporosis had significant lower hemoglobin levels (P < 0.001). Spearman correlation analysis and logistic regression analysis showed that age, female, body mass index (BMI), smoking, drinking and hemoglobin levels were significantly associated with osteoporosis in T2DM patients (all P < 0.05). After adjustment for BMI, diabetic duration, estimated glomerular filtration rate (eGFR), smoking and drinking, a significant association between hemoglobin levels and osteoporosis was observed in T2DM males aged 50 years and older (odds ratio [OR] = 0.978, 95% confidence interval [CI]: 0.958–0.998, P = 0.030). Compared to Q3 groups with normal hemoglobin levels, Q1 groups with anemia had an odd of osteoporosis increased 2.9-fold in T2DM men after adjustment for age, BMI, diabetic duration, eGFR, smoking and drinking (P = 0.032). Conclusion Hemoglobin levels were associated with the presence of osteoporosis in T2DM men, especially in those aged 50 years and older.
Transcriptome-Wide Identification of CCCH-Type Zinc Finger Proteins Family in Pinus massoniana and RR-TZF Proteins in Stress Response

CCCH-type zinc finger proteins play an important role in multiple biotic and abiotic stresses. More and more reports about CCCH functions in plant development and stress responses have appeared over the past few years, focusing especially on tandem CCCH zinc finger proteins (TZFs). However, this has not been reported in Pinaceae. In this study, we identified 46 CCCH proteins, including 6 plant TZF members in Pinus massoniana, and performed bioinformatic analysis. According to RT-PCR analysis, we revealed the expression patterns of five RR-TZF genes under different abiotic stresses and hormone treatments. Meanwhile, tissue-specific expression analysis suggested that all genes were mainly expressed in needles. Additionally, RR-TZF genes showed transcriptional activation activity in yeast. The results in this study will be beneficial in improving the stress resistance of P. massoniana and facilitating further studies on the biological and molecular functions of CCCH zinc finger proteins.
Dark Web: E-Commerce Information Extraction Based on Name Entity Recognition Using Bidirectional-LSTM

Information extraction from e-commerce platform is a challenging task. Due to significant increase in number of ecommerce marketplaces, it is difficult to gain good accuracy by using existing data mining techniques to systematically extract key information. The first step toward recognizing e-commerce entities is to design an application that detects the entities from unstructured text, known as the Named Entity Recognition (NER) application. The previous NER solutions are specific for recognizing entities such as people, locations, and organizations in raw text, but they are limited in e-commerce domain. We proposed a Bi-directional LSTM with CNN model for detecting e-commerce entities. The proposed model represents rich and complex knowledge about entities and groups of entities about products sold on the dark web. Different experiments were conducted to compare state-of-the-art baselines. Our proposed approach achieves the best performance accuracy on the Dark Web dataset and Conll-2003. Results show good accuracy of 96.20% and 92.90% for the Dark Web dataset and the Conll-2003 dataset, which show good performance compared to other cutting-edge approaches.
Fractional Generalized Random Fields of Variable Order

Abstract We study the class of random fields having their reproducing kernel Hilbert space isomorphic to a fractional Sobolev space of variable order on ℝ n . Prototypes of this class include multifractional Brownian motion, multifractional free Markov fields, and multifractional Riesz–Bessel motion. The study is carried out using the theory of generalized random fields defined on fractional Sobolev spaces of variable order. Specifically, we consider the class of generalized random fields satisfying a pseudoduality condition of variable order. The factorization of the covariance operator of the pseudodual allows the definition of a white-noise linear filter representation of variable order. In the ordinary case, the Hölder continuity, in the mean-square sense, of the class of random fields introduced is proved, and its mean-square Hölder spectrum is defined in terms of the variable regularity order of the functions in the associated reproducing kernel Hilbert space. The pseudodifferential representation of variable order of the resulting class of multifractal random fields is also defined. Some examples of pseudodifferential models of variable order are then given.

Creating a Social Presence Measure: Self-Rated Behaviors that Indicate Mediated Presence

This study involved the creation and validation of a self-rated social presence measure. Study 1 utilized focus groups to create items. The focus group participants were presented with a set of items based upon past literature; through discussion of these items, a preliminary measure was created. Study 2 involved an exploratory factor analysis on the preliminary measure to eliminate items that did not work well with each other. This reduced the measure from 54 to 23 items. Study 3 validated a 21-item self-rated measure of creating a social presence (PSP), which can be used to determine if people have difficulty projecting themselves as real individuals willing to interact with other online communicators.
Institutional Change as a Response to Unrealized Threats: An Empirical Analysis

Leaders shift political institutions to ameliorate threats to their tenure. The masses might rebel to replace the leader and change institutions. Disloyalty by political insiders might result in a coup. Leaders liberalize when the masses present a greater threat and ‘autocratize’ to dissipate threats from elites. A two-step procedure tests these arguments: (1) The risks of revolution and coup are estimated as a function of leader health, experience, economic conditions and extant institutions. (2) These risks are used to predict institutional change in a heteroskedastic regression model. The magnitude and direction of institutional change depends upon whether the masses or elites pose the greater threat. When both risks are high, leaders must gamble as to which risk they believe is greatest. In such circumstances, institutions are highly volatile even as the aggregate direction of change becomes unclear.
A eficácia terapêutica dos probióticos na acne: revisão integrativa

Os probióticos são microrganismos vivos que afetam beneficamente o hospedeiro quando administrados em quantidades adequadas, além de terem um excelente perfil de segurança. Por esse motivo, os probióticos têm sido usados como imunomoduladores em doenças inflamatórias da pele, como a acne inflamatória. Este estudo teve como objetivo avaliar a ação terapêutica do probiótico na acne. Realizou-se uma revisão integrativa da literatura. Dados quantitativos e qualitativos realizados em meio de cultura e em humanos. As buscas eletrônicas foram realizadas no PubMed/MEDLINE e BIREME, considerando os estudos publicados sem limite de data. A busca ocorreu em Outubro de 2020, utilizando uma combinação dos seguintes termos e correlatos: “probiotic” e “acne”. Foram incluídos dez estudos, sendo quatro estudos in vivo e seis in vitro. Os estudos utilizaram vários probióticos conhecidos na literatura para suplementação, obtendo resultado positivo. Entretanto, ainda são escassos os estudos que utilizam o probiótico como um tratamento para acne como coadjuvante com antibiótico ou sozinho.
