Authors: Liu Mengjia , Yu Changqiang , Liu Xiaowen , Wang Peng , Chen Yingjie
Published: January 2021

In this study, MoS2-graphene-tourmaline (MoS2-GR-T) composite photocatalyst was successful synthesized via one-step hydrothermal method. Raman spectra revealed that graphene oxide was reduced to graphene. Scanning electron microscopy images showed that MoS2 was dispersed well on graphene. Transmission electron microscope images showed that MoS2 and tourmaline contacted well with graphene. Analysis of UV-visible diffuse reflectance spectra implied that the bandgap energies of MoS2, MoS2-T and MoS2-GR-T samples were 2.01 eV, 1.91 eV and 1.79 eV, respectively. The photocatalytic performances are evidenced under Xenon lamp irradiation utilizing Rhodamine B dye as the model compound. Compared with MoS2 and MoS2-GR, the MoS2-graphene-tourmaline (MoS2-GR-T) composites exhibited the excellent photocatalytic activity for the degradation about irradiating for 60 min were 93.9% under visible-light. The enhanced photocatalytic activity of MoS2-GR-T composite could be attributed to the exposed adsorption-photocatalytic active sties, the improved light adsorption ability and the promoted charge separation efficiency. The introduction of tourmaline reduced the band gap explored by analysis of UV-visible diffuse reflectance spectra. This work demonstrated that the charge efficiency of photocatalysts could be promoted by coupling both metal-free co-catalyst and polar mineral.
The Hubble WFC3 Emission Spectrum of the Extremely Hot Jupiter KELT-9b
Authors: Changeat Quentin , Edwards Billy
Published: January 2021

Recent studies of ultra-hot Jupiters suggested that their atmospheres could have thermal inversions due to the presence of optical absorbers such as titanium oxide (TiO), vanadium oxide (VO), iron hydride (FeH), and other metal hydride/oxides. However, it is expected that these molecules would thermally dissociate at extremely high temperatures, thus leading to featureless spectra in the infrared. KELT-9 b, the hottest exoplanet discovered so far, is thought to belong to this regime and host an atmosphere dominated by neutral hydrogen from dissociation and atomic/ionic species. Here, we analyzed the eclipse spectrum obtained using the Hubble Space Telescope’s Wide Field Camera 3 and, by utilizing the atmospheric retrieval code TauREx3, found that the spectrum is consistent with the presence of molecular species and is poorly fitted by a simple blackbody. In particular, we find that a combination of TiO, VO, FeH, and H- provides the best fit when considering Hubble Space Telescope (HST), Spitzer, and TESS data sets together. Aware of potential biases when combining instruments, we also analyzed the HST spectrum alone and found that TiO and VO only were needed in this case. These findings paint a more complex picture of the atmospheres of ultra-hot planets than previously thought.
The Landscape of Galaxies Harboring Changing-look Active Galactic Nuclei in the Local Universe

Published: January 2021

We study the properties of the host galaxies of changing-look active galactic nuclei (CL AGNs) with the aim of understanding the conditions responsible for triggering CL activity. We find that CL AGN hosts primarily reside in the so-called green valley that is located between spiral-like star-forming galaxies and dead ellipticals, implying that CL AGNs are activated during distinct periods of quenching and galaxy transformation processes. CL AGN hosts have low galaxy asymmetry indicators, suggesting that secular evolutionary processes (the influence of bars and spirals, and possibly minor mergers) might be the primary mechanism for transporting gas to the vicinity of the supermassive black hole (SMBH) rather than major mergers. Similar to tidal disruption events and highly variable AGNs, we find that CL AGN hosts are associated with SMBHs residing in high-density pseudo-bulges and appear to overlap most significantly with the population of low-ionization nuclear emission-line region galaxies. As such, CL AGNs are likely fueled by strong episodic bursts of accretion activity, which appear to take place preferentially as the amount of material accessible for star formation and accretion dwindles. We also identify that CL AGN hosts are characterized by either large Sérsic indices or high bulge fractions, which suggests a simple metric for identifying candidates for spectroscopic follow-up observations in forthcoming synoptic surveys.
“It Just Hit Me Like a Ton of Bricks”: Improving the Patient Experience of Receiving a Breast Cancer Diagnosis at an Older Age
Authors: Pieters Huibrie C. , Green Emily , Sleven Miriam
Published: January 2021

The purpose of the current study was to describe the experiences of older women receiving a diagnosis of early-stage breast cancer. Thematic analysis informed by techniques from constructivist grounded theory was used to analyze interviews with 54 women aged ≥65 years an average of 19.6 months after diagnosis. Two themes were identified:
The Overwhelming Shock of Receiving a Diagnosis
and
Contextualizing the Diagnosis in Relation to Age
. Results suggest these participants were deeply shocked by a diagnosis that clinicians may view as highly treatable. Age-related factors impacting how the bad news was received include misunderstanding risk factors, the impact of comorbidities, concurrent life events, and evolving perceptions of cancer at her life stage. To establish a solid foundation for age-appropriate communication when giving bad news, these participants help clinicians acknowledge what women may be thinking. Potential clinician responses to the variety of concerns are presented. [

Re-Examining the “Native Speaker Question”
Authors: Qin Lanqing , Ibrahim Awad
Published: January 2021

This chapter addresses the native speaker question and construct from a representational point of view. Through a critical discourse analysis (CDA) of an ELT website in China's context, the authors discuss what and who is profiled as ‘native speaker' and how this category is represented on the website. Existing studies dealing with the ‘native speaker' abound, but only in recent years have a few efforts been made on the construction of this discourse, and the online representation of ELT in China is worthy of more examination. Consequently, this chapter aims to problematize the term ‘native speaker', deconstruct the process of how a discourse of ‘native speaker' takes on shape through online representation, and reveal how it is a racialized category. In conclusion, they offer pedagogical and policy implications.
The EU Language Policy as a Tool
Authors: Hocaoğlu Bahadır Neriman
Published: January 2021

The European Union (EU) is a multilingual union, which has 27 official languages. There is no other international or regional organisation that has so many official languages. Since its very beginning, the official languages of the member states are the official languages of the EU. The multilingualism of the EU is not just about the official languages of the EU but also because of the numerous indigenous regional and minority languages. The language policy of the EU can be traced back to the Treaty of Rome and the first regulation. Since then, the language policy of the EU has changed parallel with the developments and changes within the EU and in the world. First, it was evaluated as a tool for personal development and integration, but with the changes in the globalized world, it became a tool to increase the competitiveness of the EU, which can be seen as a soft power at the international level. This chapter aims to show the changing role of the EU's language policy and its current status as a powerful tool in the knowledge-based economies at the international level.

Authors: Pain Pritam , Bose Goutam Kumar , Roy Sayantan
Published: January 2021

The workpiece sample which is a copper printed circuit board (PCB) is mounted on a micro-controlled assembly with double-faced adhesive tape. Here the primary objective is to study the effect of laser cleaning parameters on surface temperature rise and thermoelastic force. The variation of instantaneous temperature rise and thermoelastic force with time using different process parameters (e.g., type of power, focal length, and scanning speed) at a constant absorption coefficient is also investigated, and the best parametric combination have been found out in this experiment. After successful completion of the experimentation, it is observed that the surface temperature increases with the increase in laser power. The maximum temperature rise is observed when the laser power is maximum, and the focal length is minimum. It is further observed that the thermoelastic force increases with the increase in laser power. Maximum thermoelastic force is observed when the laser power is maximum, and the focal length is minimum.
Experimental Evaluation on Corner Accuracy in WEDM for Aluminium 6061 Alloy
Authors: Pramanik Debal , Bose Dipankar
Published: January 2021

An important electro-thermal process known as wire electrical discharge machining (WEDM) is applied for machining of conductive materials to generate most precisely. All cutting inaccuracies of WEDM arise out of the major cause of wire bending. At the time of cutting a sharp corner or cut profile, bending of the wire leads to a geometrical error on the workpiece. Though this type of error may be of a few hundred microns, it is not suitable for micro applications. In this research study, an experimental investigation based on response surface methodology (RSM) has been done on wire EDM of Aluminium 6061 t6 alloy. This chapter studies the outcome of input process variables (i.e., wire feed rate, pulse on time, pulse off time, and gap voltage) on machining output responses (i.e., corner inaccuracy) extensively. Experimental validation of the proposed model shows that corner inaccuracy value may be reduced by modification of input parameters.

Authors: Ghosh Ramkrishna , Mohanty Suneeta , Pattnaik Prasant Kumar , Pramanik Sabyasachi
Published: January 2021

In this chapter, the authors present an innovative, smart controller to sustain mobility in wireless sensor networks (WSNs). Principally, the focal point is dependent on the arrangement of fuzzy input variables (i.e., remaining battery power [RBP], mobility, and centrality solution) to crucial usages, similar to personnel safety in an industrialized atmosphere. A mobility controller dependent upon type-1 fuzzy logic (T1FL) is planned to support sensor mobile nodes (MN). Here, a role model cluster head (RMCH) is picked out among the cluster heads (CHs) that may simply convey the message to the mobile base station (BS) by determining the appropriate type-1 fuzzy (T1F) descriptors such as RBP, mobility of the sink, and the centrality of the clusters. Type-1 fuzzy inference system (Mamdani's rule) is utilized to opt for the possibility to be RMCH. The validity of the introduced model is carried out by means of multiple linear regressions.

Deep Learning With Analytics on Edge
Authors: Srivastava Kavita
Published: January 2021

The steep rise in autonomous systems and the internet of things in recent years has influenced the way in which computation has performed. With built-in AI (artificial intelligence) in IoT and cyber-physical systems, the need for high-performance computing has emerged. Cloud computing is no longer sufficient for the sensor-driven systems which continuously keep on collecting data from the environment. The sensor-based systems such as autonomous vehicles require analysis of data and predictions in real-time which is not possible only with the centralized cloud. This scenario has given rise to a new computing paradigm called edge computing. Edge computing requires the storage of data, analysis, and prediction performed on the network edge as opposed to a cloud server thereby enabling quick response and less storage overhead. The intelligence at the edge can be obtained through deep learning. This chapter contains information about various deep learning frameworks, hardware, and systems for edge computing and examples of deep neural network training using the Caffe 2 framework.

Real Time Scheduling Optimization
Authors: Boutekkouk Fateh
Published: January 2021

This article deals with real time embedded multiprocessor systems scheduling optimization using conventional and quantum inspired genetic algorithms. Real time scheduling problems are known to be NP-hard. In order to resolve it, researchers have resorted to meta-heuristics instead of exact methods. Genetic algorithms seem to be a good choice to solve complex, non-linear, multi-objective and multi-modal problems. However, conventional genetic algorithms may consume much time to find good solutions. For this reason, to minimize the mean response time and the number of tasks missing their deadlines using quantum inspired genetic algorithms for multiprocessors architectures. Our proposed approach takes advantage of both static and dynamic preemptive scheduling. This article has the developed algorithms on a typical example showing a big improvement in research time of good solutions in quantum genetic algorithms with comparison to conventional ones.
New Hybrid Genetic Based Approach for Real-Time Scheduling of Reconfigurable Embedded Systems
Authors: Gharbi Ibrahim , Gharsellaoui Hamza , Bouamama Sadok
Published: January 2021

This journal article deals with the problem of real-time scheduling of operating systems (OS) tasks by a hybrid genetic-based scheduling algorithm. Indeed, most of real-time systems are framed with aid of priority-based scheduling algorithms. Nevertheless, when such a scenario is applied to save the system at the occurrence of hardware-software faults, or to improve its performance, some real-time properties can be violated at run-time. In contrast, most of the applications of real-time systems are based on timing constraints, i.e. OS tasks should be scheduled properly to finish their execution within the time specified by the real-time systems. For this reason, the authors propose in their article, a hybrid genetic-based scheduling approach that automatically checks the systems feasibility after any reconfiguration scenario was applied to an embedded system. A benchmark example is given, and the experimental results demonstrate the effectiveness of the originally proposed genetic-based scheduling approach over other such classical genetic algorithmic approaches.
An Improved Gravitational Clustering Based on Local Density
Authors: Chen Lei , Guo Qinghua , Liu Zhaohua , Chen Long , Ning HuiQin , Zhang Youwei , Jin Yu
Published: January 2021

Gravitational clustering algorithm (Gravc) is a novel and excellent dynamic clustering algorithm that can accurately cluster complex dataset with arbitrary shape and distribution. However, high time complexity is a key challenge to the gravitational clustering algorithm. To solve this problem, an improved gravitational clustering algorithm based on the local density is proposed in this paper, called FastGravc. The main contributions of this paper are as follows. First of all, a local density-based data compression strategy is designed to reduce the number of data objects and the number of neighbors of each object participating in the gravitational clustering algorithm. Secondly, the traditional gravity model is optimized to adapt to the quality differences of different objects caused by data compression strategy. And then, the improved gravitational clustering algorithm FastGravc is proposed by integrating the above optimization strategies. Finally, extensive experimental results on synthetic and real-world datasets verify the effectiveness and efficiency of FastGravc algorithm.
Mobile Banking Continuance Intention
Authors: Albashrawi Mousa Ahmed
Published: January 2021

User satisfaction is crucial to reinforce continued usage intention of mobile banking (MB). Since IS literature has overlooked continued usage intention of MB and its significance to reflect the success of MB system, it would be important to further the research in this area. This study employs both customization and security, two concerned factors among customers, to examine their impact on satisfaction and MB continuance intention. Extended expectation-confirmation model in IT domain (ECM-IT), developed from TAM and ECM, is used to evaluate the factors affecting satisfaction which in turn affects MB continuance intention. With a sample of a mid-sized US bank customers, regression results reveal that efficiency quality with its underlying factors of perceived usefulness and perceived ease of use are significant predictors of satisfaction. The interaction effect is significant for customization, but not for security. Theoretical and practical implications are communicated.
3-Hydroxyisobutyryl-CoA Hydrolase (HIBCH) Deficiency Cases Diagnosed by Only HIBCH Gene Analysis and Novel Pathogenic Mutation
Authors: Çakar Nafiye Emel , Görükmez Orhan
Published: January 2021

Objective:

3-Hydroxyisobutyryl-CoA hydrolase (HIBCH) deficiency is a rare metabolic disease of valine metabolism. Only 22 cases of HIBCH deficiency have been reported in the literature. Our algorithm could help in the diagnosis of this disease.

Methods:

HIBCH gene analysis was performed in all cases.

Results:

The common features of our five patients from the same family with a developmental delay, seizures, and neurological regression were the elevation of 3-hydroxy-isobutyryl-carnitine and Leigh-like abnormalities. Unlike other patients in the literature, our patients were diagnosed with HIBCH gene analysis, rather than whole exome sequencing (WES). In all our cases, a missense c.452C>T, p. Ser151Leu homozygous novel pathogenic mutation was detected in the HIBCH gene.

Conclusion:

In cases where HIBCH deficiency is considered in our differential diagnosis algorithm, HIBCH gene analysis, which is cost-effective, should be performed instead of WES, and the number of cases should be increased in the literature.

Accurate methods for identifying pelvic lymph node metastasis (LNM) of prostate cancer (PCa) prior to surgery are still lacking. We aimed to investigate the predictive value of peripheral monocyte count (PMC) for LNM of PCa in this study. Two hundred and ninety-eight patients from three centers were divided into a training set (n = 125) and a validation set (n = 173). In the training set, the independent predictors of LNM were analyzed using univariate and multivariate logistic regression analyses, and the optimal cutoff value was calculated by the receiver operating characteristic (ROC) curve. The sensitivity and specificity of the optimal cutoff were authenticated in the validation cohort. Finally, a nomogram based on the PMC was constructed for predicting LNM. Multivariate analyses of the training cohort demonstrated that clinical T stage, preoperative Gleason score, and PMC were independent risk factors for LNM. The subsequent ROC analysis showed that the optimal cutoff value of PMC for diagnosing LNM was 0.405 × 109 l−1 with a sensitivity of 60.0% and a specificity of 67.8%. In the validation set, the optimal cutoff value showed significantly higher sensitivity than that of conventional magnetic resonance imaging (MRI) (0.619 vs 0.238, P < 0.001). The nomogram involving PMC, free prostate-specific antigen (fPSA), clinical T stage, preoperative Gleason score, and monocyte-to-lymphocyte ratio (MLR) was generated, which showed a robust predictive capacity for predicting LNM before the operation. Our results indicated that PMC as a single agent, or combined with other clinical parameters, showed a robust predictive capacity for LNM in PCa. It can be employed as a complementary factor for the decision of whether to conduct pelvic lymph node dissection.

A Brazzaville, les dépendances vertes jouent un rôle important sur le bien-être et le cadre de vie des citadins. Cependant elles sont menacées de dégradation à cause d’une urbanisation mal contrôlée. Cette étude a été menée pour identifier et caractériser la biodiversité végétale de ces milieux. A cet effet, des relevés floristiques ont été réalisés au niveau de deux types de phytocénoses « dégradée » et « semi intacte » dans deux sites des quartiers périphériques de Ngamakosso et Sadelmi suivant un dispositif de 17 parcelles (30 m x 20 m). Au total, 205 espèces végétales reparties en 160 genres et 65 familles ont été inventoriées. La présence/abondance de certaines espèces et familles (Asteraceae, Rubiaceae, Poaceae) associée avec l’appréciable proportion des nanophanérophytes, révèle le caractère arbustif et perturbé de cette végétation sur des sols sableux et pauvres, favorables aux érosions. La conservation et la reconstitution des phytocénoses étudiées sont assurées grâce à des espèces endémiques, guinéo-congolaises et pantropicales, à très large distribution. Les connaissances acquises de cette étude suggèrent d’intégrer la problématique de l’aménagement des espaces végétalisés urbains dans les politiques de développement durable de la ville.

English Title: Floristic diversity of peri-urban green dependencies in Brazzaville (Congo) threatened by degradation

In Brazzaville, green dependencies have an important role in the well-being and living environment of city dwellers. However, they are threatened with degradation due to poorly controlled urbanization. This study was conducted to identify and characterize the plant biodiversity of these habitats. For this purpose, floristic surveys were carried out at the level of two kinds of "degraded" and "semi intact" phytocenosis at two sites in the outlying areas of Ngamakosso and Sadelmi following a scheme of 17 plots (30 m x 20 m). In total, 205 plant species distributed into 160 genera and 65 families were inventoried. The presence/abundance of certain species and families (Asteraceae, Rubiaceae, Poaceae) associated with the significant proportion of nanophanerophytes, revealed the shrubby and disturbed character of this vegetation on sandy, poor and erosive soils. The conservation and reconstitution of the studied phytocenosis are ensured by endemic, Guineo-Congolese and pantropical species, with very wide distribution. The knowledge acquired from this study suggests integrating the issue of vegetative landscaping into the city’s sustainable development policies.

The Adamawa region falls within the tsetse belt of Cameroon but harbours isolated pockets of tsetse free range lands like Ngaoundere. There is no report on the occurrence of tsetse and bovine trypanosomosis in Ngaoundere. To provide information on this subject, two Vavoua traps were used to trap vectors of bovine trypanosomiasis and at the same time, blood was collected from cattle. Genomic DNA was extracted from buffy coat of cattle blood (n=42) and biting flies (n=53). The nested PCR was used to screen the samples for Trypanosoma spp. During the 14 days of trapping in November and December 2017 in Ngaoundere, 127 flies were documented and classified under two taxa: Tabanidae and Stomoxyini. Three Trypanosoma spp. DNA was isolated from tabanid (18.9%) samples and identified as T. theileri, T. vivax and T. evansi and two of them that is T. theileri (4%) and T. vivax (3%) were also detected in cattle (7%). There was no case of trypanosome DNA isolated from all the screened Stomoxyini. This result indicates the “silent” transmission of T. theileri and T. vivax by tabanids in the absence of glossines in Ngaoundere.Keywords: Trypanosomes, tabanids, stomoxyini, PCR, Ngaoundere, Adamawa-Cameroon.

Au Sénégal, peu d’études sur le plan planctonique ont été réalisées pour l’évaluation de l’efficacité des Aires Marines Protégées. Dans cette perspective, la caractérisation de la flore phytoplanctonique et sa distribution spatio-temporelle à l’intérieur et à l’extérieur de l’AMP de Bamboung a été réalisée en avril et en septembre 2016. Des prélèvements d’échantillons d’eau à l’aide d’un filet à plancton de 20 μm de mailles ainsi que des mesures de paramètres physico-chimiques ont été faits dans chaque station. L’analyse des données environnementales a montré l’existence d’un effet intersaison avec des valeurs plus élevées en avril excepté la température. Par ailleurs, un effet d’inter-sites a été observé uniquement en septembre pour la température, la salinité, la conductivité et l’oxygène dissout. En termes de diversité phytoplanctonique, en avril, 49 espèces réparties dans 5 classes ont été identifiées dans l’AMP contre 47 espèces et 5 classes identifiées à Diomboss et 42 espèces et 5 classes à Sangako. En septembre, 57 espèces réparties dans 5 classes ont été répertoriées dans l’AMP contre 54 espèces et 4 classes à Diomboss, et 51 espèces réparties dans 4 classes identifiées à Sangako. Les résultats seuls de la richesse spécifique du phytoplancton ne permettent pas d’apporter une contribution sur l’évaluation de l’efficacité de l’AMP de Bamboung.

English Title: Characterization of the phytoplankton flora in the Protected Marine Area (MPA) of Bamboung and two surrounding sites (Senegal)

In Senegal, few planktonic data exist in the Marine Protected Areas (AMP). In this perspective, the characterization of phytoplankton flora and its spatial and temporal distribution within and outside the Bamboung AMP was carried out during in April and in september. Water samples were taken using a 20 μm mesh plankton net and measurements of physico-chemical parameters were made at each station. The analysis of environmental data showed the existence of an inter-site effect during the two-month sampling period. In April, 49 species in 5 classes were identified in the AMP, compared to 47 species and 5 classes identified in Diomboss and 42 species and 5 classes in Sangako. In september, 57 species distributed in 5 classes were recorded in the AMP compared to 54 species distributed in 4 classes in Diomboss and 51 species and 4 classes identified in Sangako. The results of the specific richness of phytoplankton alone do not make it possible to make a contribution to the evaluation of the effectiveness of Bamboung's MPA.Keywords: Phytoplankton, dynamics, taxonomic composition, AMP; Bamboung.
Use of essential oils in combination with fibrolytic enzymes to decrease in vitro ruminal methane production

Published: January 2021

Exogenous enzymes and essential oils (EOs) have both improved fibre digestion in ruminants, but the effect on ruminal fermentation and methane emission of combining these additives requires further evaluation. Various EOs were used in combination with an enzyme in an in vitro gas production system to measure organic matter digestibility and methane after 48 hours of incubation of Eragrostis curvula. The treatments consisted of T1) unaugmented control; T2) enzyme (cellulose-xylanase mixture, 1:1 w/w, 1.5 mL/g DM); T3) enzyme combined with Next Enhance® (cinnamaldehyde with diallyl disulfide and diallyl trisulfide, 43:3.85 w/wt); T4) enzyme and cinnamon oil; T5) enzyme and garlic oil; and T6) enzyme with cinnamon and garlic oil, 1:1 w/w). At 2, 4, 8, 12, 24, 36, and 48 hours of incubation, gas production was measured, and gas samples were analysed for methane concentration. The inclusion of additives affected cumulative gas production (P <0.05), but only slightly affected methane production (P =0.05) after 48 hours of incubation. The addition of enzymes increased both gas and methane production. T5 and T6 both reduced gas production compared with T2. Combining EOs with an enzyme reduced methane production compared with T2 after 48 hours of incubation. The additives tended to increase in vitro organic matter digestibility (P =0.09), although they showed a tendency towards reduced methane production per unit of organic matter digested (P =0.07). Further studies on these enzyme and EO combinations under different doses and substrates are required to validate their efficacy for ruminant production.
