The Significance of the Incident of Pentecost in the Book of Acts for Christian Mission Today
Authors: Nuekpe Dieudonne Komla
Published: July 2022

The event of Pentecost in the book of Acts can be viewed as a continuation of the salvation drama initiated by God; it has some connection with the Jewish feast of Shavuot and the work of the Holy Spirit in the Old Testament. The event is generally understood as the Holy Spirit’s outpouring and has great significance for the Christian mission. By means of the literary qualitative research method, this paper defines the Christian mission and traces the event of Pentecost from the Holy Spirit’s missional work in the Old Testament, emphasizing the significance of the outpouring in Acts for Christian Mission in Evangelism, Leadership, Character Transformation and Cross-cultural mission. Using the church of Pentecost as an example, the paper concludes that the incident of Pentecost is most significant in the growth of Pentecostal Movements. In addition to the Holy Spirit’s work, good education, proper planning and good mission strategies are recommended for effective Christian Mission. Keywords: Pentecost, Christian Mission, Holy Spirit, Cross-cultural mission
Neutrino Emissivities as a Probe of the Internal Magnetic Fields of White Dwarfs
Authors: Drewes Marco , McDonald Jamie , Sablon Loïc , Vitagliano Edoardo
Published: July 2022

The evolution of white dwarfs (WDs) depends crucially on thermal processes. The plasma in their core can produce neutrinos that escape from the star, thus contributing to the energy loss. While in the absence of a magnetic field the main cooling mechanism is plasmon decay at high temperature and photon surface emission at low temperature, a large magnetic field in the core hiding beneath the surface even of ordinary WDs, and undetectable to spectropolarimetric measurements, could potentially leave an imprint in the cooling. In this paper, we revisit the contribution to WD cooling stemming from neutrino pair synchrotron radiation and the effects of the magnetic field on plasmon decay. Our key finding is that even if observations limit the magnetic field strength at the stellar surface, magnetic fields in the interior of WDs—with or without a surface magnetic field—can be strong enough to modify the cooling rate, with neutrino pair synchrotron emission being the most important contribution. This effect may not only be relevant for the quantification and interpretation of cooling anomalies, but suggests that the internal magnetic fields of WDs should be smaller than ∼ 6 × 1011 G, slightly improving bounds coming from a stability requirement. While our simplified treatment of the WD structure implies that further studies are needed to reduce the systematic uncertainties, the estimates based on comparing the emissivities illustrate the potential of neutrino emission as a diagnostic tool to study the interior of WDs.

Published: July 2022

We report results for a complete sample of 10 luminous radio-quiet quasars with large C iv equivalent widths (EW ≥ 150 Å). For 8/10 we performed Chandra snapshot observations. We find that, in addition to the enhanced C iv line EW, their He ii and Mg ii lines are enhanced, but the C iii] line is not. Their X-ray emission is substantially stronger than expected from their ultraviolet luminosity. Additionally, these large C iv EW quasars show small C iv blueshifts and possibly low Eddington ratios, suggesting that they are “extreme low Eigenvector 1 (EV1)” quasars. The mean excess He ii EW is well matched by radiation pressure compression (RPC) photoionization models, with the harder α
ox ionizing spectrum. However, these results do not reproduce well the enhancement pattern of the C iv, Mg ii, and C iii] EWs, or the observed high C iv/Mg ii ratio. RPC calculations indicate that the C iv/Mg ii line ratio is an effective metallicity indicator, and models with subsolar-metallicity gas and a hard ionizing continuum reproduce well the enhancement pattern of all four ultraviolet lines. We find that the C iv/Mg ii line ratio in quasars is generally correlated with the excess X-ray emission. Extremely high EV1 quasars are characterized by high metallicity and suppressed X-ray emission. The underlying mechanism relating gas metallicity and X-ray emission is not clear but may be related to radiation-pressure-driven disk winds, which are enhanced at high metallicity, and consequent mass loading reducing coronal X-ray emission.

We predict the rates at which events like AT2018cow and AT2020mrf will be detected by SRG and Einstein Probe.

Published: July 2022

Recently, a new class of white dwarfs (“slowly cooling WDs”) has been identified in the globular cluster M13. The cooling time of these stars is increased by stable thermonuclear hydrogen burning in their residual envelope. These WDs are thought to be originated by horizontal branch (HB) stars populating the HB blue tail that skipped the asymptotic giant branch phase. To further explore this phenomenon, we took advantage of deep photometric data acquired with the Hubble Space Telescope in the near-ultraviolet and investigate the bright portion of the WD cooling sequence in NGC 6752, another Galactic globular cluster with a metallicity, age, and HB morphology similar to M13. The normalized WD luminosity function derived in NGC 6752 turns out to be impressively similar to that observed in M13, in agreement with the fact that the stellar mass distribution along the HB of these two systems is almost identical. As in the case of M13, the comparison with theoretical predictions is consistent with ∼70% of the investigated WDs evolving at slower rates than standard, purely cooling WDs. Thanks to its relatively short distance from Earth, NGC 6752 photometry reaches a luminosity 1 order of a magnitude fainter than the case of M13, allowing us to sample a regime where the cooling time delay, with respect to standard WD models, reaches ∼300 Myr. The results presented in this paper provide new evidence for the existence of slowly cooling WDs and further support to the scenario proposing a direct causal connection between this phenomenon and the HB morphology of the host stellar cluster.

AMEGO-X, the All-sky Medium Energy Gamma-ray Observatory eXplorer, is a proposed instrument designed to bridge the so-called “MeV gap” by surveying the sky with unprecedented sensitivity from ∼100 keV to about 1 GeV. This energy band is of key importance for multimessenger and multiwavelength studies but it is nevertheless currently underexplored. AMEGO-X addresses this situation by proposing a design capable of detecting and imaging gamma rays via both Compton interactions and pair production processes. However, some of the objects that AMEGO-X will study, such as gamma-ray bursts and magnetars, extend to energies below ∼100 keV where the dominant interaction becomes photoelectric absorption. These events deposit their energy in a single pixel of the detector. In this work we show how the ∼3500 cm2 effective area of the AMEGO-X tracker to events between ∼25 and ∼100 keV will be utilized to significantly improve its sensitivity and expand the energy range for transient phenomena. Although imaging is not possible for single-site events, we show how we will localize a transient source in the sky using their aggregate signal to within a few degrees. This technique will more than double the number of cosmological gamma-ray bursts seen by AMEGO-X, allow us to detect and resolve the pulsating tails of extragalactic magnetar giant flares, and increase the number of detected less-energetic magnetar bursts—some possibly associated with fast radio bursts. Overall, single-site events will increase the sensitive energy range, expand the science program, and promptly alert the community of fainter transient events.

Published: July 2022

We report a very bright, long-duration gamma-ray burst (GRB), GRB 220426A, observed by the Fermi satellite. GRB 220426A, with a total duration of T
90 = 6 s, is composed of two main pulses and some subpeaks. The spectral analysis of this burst with a Band function reveals that both the time-integrated and the time-resolved spectra are very narrow with a high α ≳ 0.2 and low β ≲ −3.1. It is highly reminiscent of GRB 090902B, a special GRB with a photospheric emission identification. Then, we perform the spectral analysis of this burst based on nondissipated photospheric emission, which can be well modeled by a multicolor blackbody with a cutoff power-law distribution of the thermal temperature. The spectral fittings reveal that the photospheric emission can well describe the radiation spectrum of this burst. We conclude that this burst would be a second burst in the class of GRB 090902B observed by the Fermi satellite. We also discuss the physics of the photosphere and the origin of the high-energy component in GRB 220426A.
Approximate Relation Between Integral Albedo and Single-scattering Albedo of the Particulate Media
Authors: Petrov Dmitry
Published: July 2022

The radiative transfer model makes it possible to establish relationships between the single scattering albedo and the integral albedo of a medium consisting of particles. In this paper, an approximation is proposed for solving the inverse problem—calculating the albedo of a single scattering of a particle, based on the known value of the integral albedo. This approximation can be useful to all researchers involved in the photometry of solar system bodies with regolith-like surfaces.

Published: July 2022

Introduction: Tuberculosis (TB) is an infectious, transmissible and immune disease caused by the Mycobacterium tuberculosis-complex (MTBC). Although osteoarticular tuberculosis (OATB) has been widely described, the ribcage variety remains a rare form.

Case report: A thirteen-month-old male and a twenty-month-old female, both with pain and increased volume of anterolateral left rib cage were described. Physical examination revealed the presence of a soft consistent mass at the level of the 9th and 5th costal arches in the male and female patients respectively. Upon clinical evaluation, tuberculosis was suspected, which was confirmed by X-ray and histopathological studies. After confirmation, the management, based on anti-tuberculosis therapy was started as follows: nine months of anti-tuberculosis therapy for the male patient and fourteen months for the female. The outcomes were favorable for both patients. However, further interventions, consisting of abscess drainage in the male patient and excisional biopsy in the female patient were necessary. With these therapeutic interventions, to date, the patients are without any evidence of active TB.

Introduction: Secondary Bacterial Infections (SBIs) of the respiratory system are one of the biggest medical concerns in patients undergoing hospitalization with a diagnosis of COVID-19. This study aims to provide relevant data for the initiation of appropriate empirical treatment after examining the etiology and antimicrobial resistance of SBIs in COVID-19 patients under care in the Intensive Care Units (ICUs) in the largest pandemic hospital of our country.

Methodology: Between March 16, 2020 and December 31, 2021, 56,993 COVID patients were hospitalized, of which 7684 were admitted to ICUs. A total of 1513 patients diagnosed with SBIs have been included in this study. During the course of the study, demographic data, clinical course, etiology and antimicrobial resistance data of all patients were collected.

Results: The most common causative agents of SBIs were inferred as Acinetobacter baumanii (35.1%), Staphylococcus aureus (15.2%), Klebsiella pneumoniae (12.3%) and Pseudomonas aeruginosa (10.4%). The isolation rates of carbapenem-resistant and colistin-resistant A. baumannii, K. pneumoniae and P. aeruginosa were 83.7%; 42.7%, 79.2%, and 5.6%, 42.7%, 1.7%, respectively. Acinetobacter pittii clustering was seen in one of the ICUs in the hospital. Multidrug resistant 92 (5.4%) Corynebacterium striatum isolates were also found as a causative agent with increasing frequency during the study period.

Conclusions: SBI of the respiratory system is one of the major complications in patients hospitalized with COVID-19. The antimicrobial resistance rates of the isolated bacteria are generally high, which indicates that more accurate use of antibacterial agents is necessary for SBIs in patients hospitalized with COVID-19 diagnosis.
The Effect of Topical and Oral Phenytoin on Increasing Wound Healing of Enterocutaneus Fistula in Wistar Rat
Authors: Kurniawan Victor , Hardian Hardian , Riwanto Ignatius
Published: July 2022

BACKGROUND: Enterocutaneous fistula is an abnormal connection between gastrointestinal tract with skin or wound and studies showed low numbers of spontaneous fistula closure (20–30%) despite proper wound treatment and nutrition with high morbidity and mortality rate in fistula repair operation. Phenytoin, commonly used as an anticonvulsant, has shown its effects on wound healing process such as promoting fibroblast activities, formation of granulation tissue, reduction of collagenase activities, increasing collagen production, and other connective tissue components, reducing bacterial colonization, and reducing wound exudate.

AIM: To assess the effects of phenytoin in enterocutaneous fistula wound healing in Wistar rats (Ratus norvegicus).

MATERIALS AND METHODS: This is an experimental study with randomized post-test only design on 20 Winstar rats. A 5 mm enterocutaneous fistula was made on the rat’s stomach and the rats were assigned randomly into three groups: K (control), P1 (10% phenytoin ointment), and P2 (0.03 mg/g oral phenytoin). The groups were terminated on day 7 and wound histological slides were made. The data were analyzed using SPSS software.

RESULTS: The delta diameter is highest in P1 group (mean + SD 0.928 + 0.078), followed by P2 (mean + SD 0.770 + 0.145), and control (mean + SD 0.411 + 0.120). There is a significant difference, p < 0.05 (0.000), between P1 and P2, indicating that oral phenytoin is more effective in collagen formation than topical phenytoin. There is no significant difference between P1 and P2, p < 0.05 (0.269), indicating that oral phenytoin is not more effective than topical phenytoin in granulation tissue in enterocutaneous fistula in Wistar rats.

CONCLUSION: Administration of topical and oral phenytoin was effective in increasing granulation tissue thickness, increasing collagen amount in wound tissue, and reducing the diameter of enterocutaneous fistulas in Wistar rats compared with control on the seventh day.
­­­Status and distribution of an introduced population of European Goldfinches (Carduelis carduelis) in the western Great Lakes region of North America
Authors: Craves Julie , Anich Nicholas
Published: July 2022

Monitoring introduced species is important because of possible effects on native species and ecosystems. Here, we report on European Goldfinch observations from North America between 2001–2021, focusing on a population in the western Great Lakes region. We compiled over 7000 records of European Goldfinches from multiple sources for this time period. Over 3300 records were from the western Great Lakes region. We believe the primary founding event of this population to be release or escape from a cage bird importer in northern Illinois.  European Goldfinches were initially reported widely in the region, but over time birds were most consistently reported between Milwaukee, Wisconsin and Chicago, Illinois. They have been breeding in this area continuously since 2003, are currently present in numbers that have established them as part of the local avifauna, and show evidence of a recent increase in numbers.  More study is needed on this population of European Goldfinches, including their ecology, their potentially increasing range and population, and an evaluation of the potential for impacts on native ecosystems.
Enquête sur le sentiment et l’engagement religieux de Montaigne
Authors: Legros Alain
Published: July 2022

Montaigne était-il dénué de tout sentiment religieux, comme le pense une certaine doxa critique ? Tel n’est pas l’avis d’Alain Legros . Certes, les Essais , ce lieu délibérément profane où Montaigne teste son jugement, n’ont pas vocation à exposer sa piété, mais on trouve ici et là les indices d’une réelle ferveur, toute de reconnaissance à l’égard du don divin de la vie. Quant à son engagement dans la société de son siècle en proie aux guerres civiles, il est resté d’un bout à l’autre fidèle à l’Église catholique et au roi de France, donc opposé aux protestants, pour lui doctrinaires et séditieux (adversaires toutefois plus qu’ennemis), mais sans se référer à un principe de tolérance.
Que veut dire pour le sujet et pour ce qu’on appelle Dieu exister dans l’asymétrie ? Une lecture contrastive du christianisme à partir d’ Autrement qu’être d’Emmanuel Levinas
Authors: Gisel Pierre
Published: July 2022

Le texte qui suit est celui d’une intervention de Pierre Gisel , le 19 octobre 2021, dans le séminaire de Danielle Cohen-Levinas de la rue d’Ulm, « Lectures lévinassiennes. “Subjectivité” : phénoménologie, éthique et philosophie de la religion ». Le texte propose une lecture serrée de l’ouvrage Autrement qu’être d’Emmanuel Levinas. Outre la tentative d’en restituer l’axe en matières de Dieu et de subjectivité, il s’efforce de repenser certains mots lourds de la tradition chrétienne dont use Levinas, tels incarnation, passion, expiation, substitution. Il le fait ici à l’écart tant de certains lecteurs juifs qui soupçonnent Levinas de complaisance à l’endroit du christianisme, ou tout au moins de trop grande proximité, que de lecteurs chrétiens qui récupèrent trop vite, voire faussement, sa pensée, tout particulièrement en lien aux thématiques du visage, d’autrui et de l’altérité. À regarder de près, les mots du christianisme que reprend ici Levinas sont l’objet de subtils décalages, de fait selon une perspective juive, à quoi s’ajoute que, certes surchargés de résonances chrétiennes, ce sont des mots de la langue commune.
Église-famille en exil : sacrement de guérison holistique ? Transnationalité d’un concept ecclésial dans les Églises africaines issues de l’immigration en Suisse
Authors: Zabsonre Neree
Published: July 2022

Tel qu’il s’est développé en Afrique subsaharienne, le concept d’ Églisefamille de Dieu désigne un lieu sacramentel quand cet espace dépasse le cadre d’une maison habitée pour devenir l’endroit même de la guérison holistique des chrétiens bantu . Selon Neree Zabsonre , cette thèse paraît pertinente pour qualifier les Églises et communautés africaines issues de l’immigration en Europe. Sous l’angle de la transnationalité de cette ecclésiologie africaine en Suisse, l’aspiration à une santé intégrale laisse percevoir de nouveaux imaginaires et des représentations qui jalonnent le parcours singulier des migrants africains, particulièrement Congolais, en quête d’épanouissement.

Published: July 2022

La crise sanitaire de la Covid-19 fait entendre de nouveau le nom du « Vietnam ». Pays cité par les institutions mondiales comme un exemple de gestion publique de la pandémie, le Vietnam est pourtant situé aux portes de la Chine, « l’œil du cyclone », et ne dispose que de ressources limitées. Cette contribution propose une analyse de la maîtrise de la crise Covid-19 par l’État vietnamien en privilégiant une approche culturelle. Il s’agit de comprendre dans quelle mesure des éléments socio-historico-culturels sont perçus au Vietnam comme des facteurs explicatifs de la mise en œuvre réussie des actions publiques.
Consentement à l’effort et Covid-19 : Les apports du management par le care au management public
Authors: Benzerafa-Alilat Manel , Ardelet Caroline
Published: July 2022

Cet article traite du consentement à l’effort qui est au cœur de l’acceptabilité des mesures décidées par l’ensemble des gouvernements pour lutter contre la pandémie. L’étude expérimentale menée à la fin du premier confinement compare le degré de consentement à l’effort pendant la crise à celui consenti hors contexte de crise. Les résultats confirment que, dans ces deux contextes, le consentement à l’effort est d’autant plus fort que les répondants perçoivent que les injonctions relèvent d’une volonté de manager par le care, c’est-à-dire dans le but de prendre soin de la population.

Cet article questionne la capacité des musées français à faire preuve de résilience organisationnelle face à la crise sanitaire. La nature complexe et contingente de ces établissements nous a conduits à employer une méthodologie exploratoire holistique à même de répondre à leurs caractéristiques. Nous avons construit, sur la base de données secondaires (rapports officiels, guides et webinaires), une taxonomie pragmatique selon la méthode de Grémy et Le Moan (1977), permettant ainsi de répondre à une confusion généralisée dans les sciences humaines et sociales sur les procédures de classification. Cinq dimensions ressortent dans cette taxonomie, révélant la capacité de résilience muséale.

Cet article concerne la gestion et l’accueil des rapatriés de Wuhan à l’Ensosp (France) au début de la pandémie de la Covid-19 en Chine. Il contribue à éclairer les processus d’improvisation en période d’incertitude pour tirer des enseignements utiles aux managers. Nous avons ainsi dégagé qu’en situation extrême, la réponse aux imprévus peut donner lieu à des cycles d’apprentissages expérientiels (Kolb, 2014). Nous proposons de les considérer comme des cycles rapides de micro-apprentissages se déroulant en environnement contraint (contraintes de ressources, temps court de réaction). Ces micro-apprentissages s’opèrent dans les interactions entre individus au sein des organisations.
La crise sanitaire : un contexte capacitant ?
Authors: Beaucourt Christel , Roux Laëtitia
Published: July 2022

Comme dans toute crise sanitaire, les professionnels et organisations ont dû faire face à l’urgence et la déstabilisation. Certains ont été débordés voire submergés. Toutefois, notre analyse de 11 entretiens avec des dirigeants ou cadres dirigeants de structures situées dans le champ du handicap ou des personnes âgées, montrent que la crise sanitaire a également pu être un contexte capacitant, propice au développement des « capabilités » (Sen, 1990) des individus et des organisations. Face à une situation inédite, les protocoles, scripts, référentiels qui organisent habituellement l’action ont été secondarisés pour laisser place, ici ou là, à l’intuition, l’agilité, l’ingéniosité ou la débrouillardise des professionnels. En cela, la crise sanitaire a bel et bien révélé l’adaptabilité des acteurs, leur désir d’autonomie en venant par ailleurs interroger les pratiques organisationnelles et managériales.

Fiber entropy and algorithmic complexity of random orbits
Authors: Zimmermann Elias
Published: July 2022

Let \begin{document}$ \Theta $\end{document} be a finite alphabet. We consider a bundle of measure preserving transformations \begin{document}$ (T_{\theta})_{\theta \in \Theta} $\end{document} acting on a probability space \begin{document}$ (X,\mu) $\end{document}, which are chosen randomly according to an ergodic stochastic process \begin{document}$ (\Xi,\nu,\sigma) $\end{document} with state space \begin{document}$ \Theta $\end{document}. This describes a paradigmatic case of a random dynamical system (RDS). Considering a finite partition \begin{document}$ \mathcal{P} $\end{document} of \begin{document}$ X $\end{document} we show that the conditional algorithmic complexity of a random orbit \begin{document}$ x, T_{\alpha_{0}}(x),T_{\alpha_{1}}\circ T_{\alpha_{0}}(x),... $\end{document} in \begin{document}$ X $\end{document} along a sequence \begin{document}$ \alpha = \alpha_{0}\alpha_{1}\alpha_{2}... $\end{document} in \begin{document}$ \Xi $\end{document} equals almost surely the fiber entropy of the RDS with respect to \begin{document}$ \mathcal{P} $\end{document}, whenever the latter is ergodic. This extends a classical result of A. A. Brudno connecting algorithmic complexity and entropy in deterministic dynamical systems.
An improvement in maximum likelihood estimation of the Burr XII distribution parameters
Authors: Al-Shomrani Ali A.
Published: July 2022

In this paper, we discuss the parameters estimation of the Burr XII distribution. We know that the most popular method in the literature for parameter estimation is the maximum likelihood method. However, the maximum likelihood estimators (MLEs) are widely known to be biased for small sample sizes. Therefore, this motivate us to obtain approximately unbiased estimators for this distribution' parameters. Precisely, we focus on two bias-correction techniques (analytical and bootstrap approaches) to reduce the biases of the MLEs to the second order of magnitude. In order to compare the performance of these estimators, Monte Carlo simulations are conducted. Lastly, two real-data examples are provided to show the usefulness of these proposed estimators when sample sizes are small.
Multipoint flux mixed finite element method for parabolic optimal control problems
Authors: Zhang Tiantian , Xu Wenwen , Li Xindong , Wang Yan
Published: July 2022

In this paper, we research semi-discrete multipoint flux mixed finite element (MFMFE) method for parabolic optimal control problem (OCP). The state and co-state variables are approximated by the lowest order Brezzi-Douglas-Marini (BDM) mixed finite element (MFE) spaces and the control is approximated by piecewise constant. The advantage of this type of mixed element method is that it can decouple the state and adjoint state variables as cell-centered difference schemes rather than to solve saddle point algebraic equations. Error estimates and convergence orders are derived rigorously for state and control variables. Finally, a numerical example is given to confirm our theoretical analysis.
Approximation of solutions for nonlinear functional integral equations
Authors: Mishra Lakshmi Narayan , Pathak Vijai Kumar , Baleanu Dumitru
Published: July 2022

In this article, we consider a class of nonlinear functional integral equations, motivated by an equation that offers increasing evidence to the extant literature through replication studies. We investigate the existence of solution for nonlinear functional integral equations on Banach space $ C[0, 1] $. We use the technique of the generalized Darbo's fixed-point theorem associated with the measure of noncompactness (MNC) to prove our existence result. Also, we have given two examples of the applicability of established existence result in the theory of functional integral equations. Further, we construct an efficient iterative algorithm to compute the solution of the first example, by employing the modified homotopy perturbation (MHP) method associated with Adomian decomposition. Moreover, the condition of convergence and an upper bound of errors are presented.
Bifurcations of an SIRS epidemic model with a general saturated incidence rate
Authors: Zhang Fang , Cui Wenzhe , Dai Yanfei , Zhao Yulin
Published: July 2022

This paper is concerned with the bifurcations of a susceptible-infectious-recovered-susceptible (SIRS) epidemic model with a general saturated incidence rate $ k I^p/(1+\alpha I^p) $. For general $ p > 1 $, it is shown that the model can undergo saddle-node bifurcation, Bogdanov-Takens bifurcation of codimension two, and degenerate Hopf bifurcation of codimension two with the change of parameters. Combining with the results in [1] for $ 0 < p\leq 1 $, this type of SIRS model has Hopf cyclicity $ 2 $ for any $ p > 0 $. These results also improve some previous ones in [2] and [3], which are dealt with the special case of $ p = 2 $.

In this paper, considering that sometimes signal transmission may be interrupted, or signal input errors may occur, we establish a novel class of parametric uncertainty hybrid control system models including the impulsive control signals under saturated inputs, which can reflect the signal transmission process more realistically. Based on the step-function method, improved polytopic representation approach and Schur complement, we find the stability conditions, which are less conservative than those with the traditional Lyapunov method, of the considered control system. In addition, we investigate the design of the control gains and the auxiliary control gains for easily finding the suitable control signals, the auxiliary signals and the estimation of the attraction domain. Moreover, our proposed methods are applied to the fixed time impulse problems of uncertain systems with or without Zeno behavior. Simulation results for the uncertain neural network systems are presented to show the feasibility and effectiveness of our stabilization methods using the step-function.

Daylight affects our health and comfort. Recently, occupants face thermal and visual comfort problems due to the lack of solar control elements and improper design decisions of glazed surfaces. Recent studies show that solar control systems and window-based variables are some of the most significant variables which influence daylight performance. This study aims to test various combinations of window sizes and light shelf scenarios for a uniform distribution of daylight and visual comfort of occupants in two architecture studios in the İzmir Institute of Technology (IZTECH) Campus. In scenarios; window size and location, exterior and interior light shelves’ height, incline angle, and materials are tested. It is concluded that variables significantly improved the uniform distribution of daylight of both studios and sun patch areas of the south/east-oriented studio. Also, the artificial light requirement of the south/west-oriented studio is improved by 29.36% and 31.75% for the 21st of June and December respectively.

COVID-19 is a pathogenic viral infection caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), which emerged in Wuhan, China in December 2019 and has spread to several countries of the world resulting in economic hardship and travel restrictions. This paper presents findings on the baseline study of COVID-19 and biometric technologies. The study included succinct discussions on biometric technologies prior to and since outbreak of COVID-19 and an online survey involving 2438 randomly selected individuals via questionnaire that centered on the world's economy with daily application of biometric technologies. The questionnaire featured indices on biometric technologies and global security, the rating of each biometric mode in the global security performance scale among others. Analysis of data from the survey established the paradigm shift in biometric applications from contact-based to contact-free since the outbreak of the disease, low risk level between COVID-19 and biometric technologies and diminishing cash flow in biometric market.

Fig tree (Ficus carica L., Moraceae), which originated in the Mediterranean Basin, is one of the many fruit trees grown in Brazil, with ‘Roxo-de-Valinhos’ being the exclusively used cultivar. In this context, research aimed at the improvement of this species to develop highly resistant and adaptable cultivars is paramount. Thus, the present study aimed to maintain fig accessions in an in vivo active germplasm bank (AGB) at the Faculty of Engineering of Ilha Solteira (FEIS), São Paulo State University (UNESP), as well as to characterize the agronomic traits of these accessions based on quantitative descriptors of genetic parameters and observe gains with the selection of specific genotypes to illustrate the AGB in terms of genetic variability. A total of 36 F. carica genotypes were evaluated in the field at the Teaching, Research and Extension Farm (FEPE) of the FEIS, UNESP. Qualitative traits, fruit parameters (e.g., insertion of the first fruit, fruit stalk length, fruit length, fruit diameter, and average fruit mass), and accumulated plant dry mass were measured. In addition, genetic parameters, variance components, and descriptive statistics, including genetic and environmental variances, heritability and average heritability of clones, coefficients of genotypic and environmental variation and their ratio ( ), general average, and selection gain, were evaluated. The selected fig tree accessions showed genetic variability in the assessed traits, exhibiting good heritability and achieving selection gains. For instance, the first 10 classified clones exhibited a heritability of 80.2% and achieved a selection gain of 98% for accumulated plant dry mass. Therefore, the maintenance of in vivo AGBs allows agronomic studies, offering promising results for continuing the breeding programs and preserving the genetic variability of species.

The cultivation of special corns, such as baby corn, has had a positive influence on the economy of the country. Despite its importance, there is still a need for studies aimed at increasing production and planting areas of the crop. Phytosanitary studies are of particular interest, as the cultivation of such crops is susceptible to a series of pathogens, such as Bipolaris maydis, Exserohilum turcicum, and Puccinia polysora. The use of resistant cultivars is the most effective way to prevent the occurrence of these diseases. Thus, the present study aimed to identify popcorn lines that have the potential for baby corn production and are resistant to the main leaf diseases that affect the crop. The experiment was conducted in randomized blocks with four replications of 30 lines in each area, during two planting seasons. The area was located at the Federal Institute of Espírito Santo (IFES) Campus of Alegre, situated in Rive district, Espírito Santo State, Brazil. Using the obtained data, the area under the disease progress curve was obtained. Subsequently, analysis of the joint variance of the data was conducted, and when a significant effect was found, a grouping of means test was conducted. The Mahalanobis distance for each pair of lines was also calculated, and the genetic distance matrix was used to construct a dendrogram using the UPGMA method. Considering the averages obtained for the three diseases (Southern corn leaf blight, Northern corn leaf blight, and Southern rust), lines L61, L63, L65, L683, L684, L685, L691, L694, and L695 were identified as possible donors of resistance alleles for multiple diseases. Multivariate analysis efficiently grouped the lines L61, L63, L684, L685, and L691, which are described as most resistant in the univariate analysis.

Brachiaria brizantha is the most economically important forage grass in Brazil and is propagated through sowing. Producing high-quality seeds has been a constant challenge due to their uneven maturation. The development and application of precise and non-destructive methods for identifying internal damages to seeds, such as the X-ray test, which quickly indicates the quality of the lots, is of fundamental importance for the seed industry. In this work, the quality of Brachiaria brizantha seeds was analyzed based on the morphological characteristics observed in X-ray images that were related to viability using a mixture model under a Bayesian approach, with the following objectives: i) verify the adequacy of the Bayesian modeling used in the data analysis; ii) associate the efficiency of using radiographs as a way to assess the viability of the seeds; and iii) relate the classifications carried out by evaluators with the probability of originating normal or abnormal seedlings. The methodology applied for the analysis proved to be adequate. Further, the Bayesian estimates for parameters related to internal morphology were established with associated levels of uncertainty, which represents an advantage over usual frequentist methods. Based on the model's estimates, seeds evaluated as potentially unviable by three evaluators had practically no probability of germination and did not germinate in the test applied later. Seeds classified as potentially viable had a high probability of developing into normal seedlings, while 73.27% showed this property in the germination test.

This study evaluated the effect of increased energy via supplementation on the performance, ingestive behavior, nutrient digestibility, and nitrogen metabolism of grazing heifers fed tropical forage in the rainy-dry transition season. Treatments consisted of mineral supplementation ad libitum (control) and multiple supplements formulated to provide different energy levels and the same amount of protein (300 g CP animal d-1) and were denominated as low (LE; 340 g TDN animal d-1), medium (ME; 780 g TDN animal d-1) and high (HE; 1220 g TDN animal d-1) energy. Animals supplemented with ME, and HE had a greater average daily gain in relation to the control treatment, with an increase of 41 and 46%, respectively. Greater values for total apparent digestibility of neutral detergent fiber were observed for the treatment HE. Lesser values of urinary urea N were observed for the control and HE treatments. Our results define the use of energy levels in the supplement as a tool for pasture management. If the purpose of the production system is to enhance forage intake, the option is to supply supplements with less energy levels. In contrast, if the purpose is to increase the stocking rate, supplements with greater energy levels should be used.

A diverse group of rangeland-medicinal plants are being used by ruminant whilst some of them have not been assessed for their nutritional value. This study was aimed to evaluate the chemical and mineral composition, buffering capacity, and in vitro fermentation of some rangeland-medicinal plants including Thymus kotschyanus, Ziziphora persica, Lallemantia royleana, and Scutellaria litwinowii in the family Lamiaceae, and Hypericum scabrum, in the family Hypericaceae. The results indicated that crude protein (CP) content ranged from 8.66% (S. litwinowii) to 12.17% of DM (H. scabrum). It was found that Z. persica had the highest potential gas production, metabolism energy (ME), relative feed value (RFV), and dry matter digestibility (DMD) values of 53.44 (mL 200-1 mg DM), 5.84 (MJ kg-1 DM), 170.66 and 70.88%, respectively. Mineral content differed among plants; Ca ranged from 5.79 to 41.96 g kg-1 DM. The concentrations of Ca, K, Mg, Fe, Zn, and Co were highest for L. royleana. Total volatile fatty acids (TVFA) and propionate concentrations were highest in the culture medium cultured with Z. persica, however, acetate, and butyrate were highest in H. scabrum. Acid-base buffering capacity was lower in T. kotschyanus and H. scabrum compared to other plants, while it was higher in S. litwinowii. Overall, it can be concluded that among plants evaluated in this study, Z. persica had higher nutritional value for sheep feeding.

The study characterized the lactoferrin (Lf) mRNA gene in different goat breeds in the Philippines and determined its association with subclinical mastitis (SCM). The study involved collection of milk at second week of lactation (n=75) and blood samples (n=5) to obtain extracted RNA and using cDNA to amplify Lf gene through polymerase chain reaction. The nucleotide and amino acid sequences were determined and used as reference in the evaluation of phylogenetic relationship. Amplified products were utilized for RFLP analysis before determining the association of the gene with SCM. Results of the study demonstrated that Lf gene in goats registered a molecular weight of 2135. Nucleotide and amino acid sequence of Lf gene revealed high similarity (99%) in Saanen, Anglo-Nubian and Philippine native goats with that of Capra hircus (U53857) Lf gene submitted to GenBank. Phylogenetic studies showed that Lf gene of Anglo-Nubian, Saanen and Native goats clade together with Lf gene of C. hircus (U53857). Three genotypes in goats were documented using the restriction enzymes AluI and HaeIII. Based on the Statistical analysis, association (comp 5.65, p = 0.0308) has been established between the Lf genes of goats with genotype BB to SCM using HaeIII restriction enzyme.
