Reconstructing one- and two-bifurcation diagrams of all components in the Rössler equations only from time-series data sets

We reconstruct bifurcation diagrams of all components in the Rössler equations only from time-series data sets, thereby estimating the attractors when the parameter values are changed. In this study, we show that the bifurcation diagrams of all components can be reconstructed from time-series data of all components. In addition, we estimate the Lyapunov spectrum of the reconstructed bifurcation diagrams. We expect that the reconstruction requires a shorter length of training data when using time-series data sets of all components compared with one component. Accordingly, in numerical experiments, we reconstruct the bifurcation diagrams using training data whose length is shorter than when a bifurcation diagram is reconstructed using training data of one component.
Trends of Temperature Extreme Indices over Arusha and Kilimanjaro Regions in Tanzania

The study aimed at analyzing the trends and variability of temperature extremes over the northeastern highlands in Tanzania, specifically over Arusha and Kilimanjaro regions. Quality controlled mean monthly, daily maximum and minimum temperature data for the period 1961 to 2020, obtained from Tanzania Meteorological Authority, were used in the study. Rclimdex and the National Climate Monitoring Products (NMCP) software, developed by the World Meteorological Organization (WMO), were used for computation of the indices at a monthly, seasonal and annual time scale. The computed indices were also subjected to trend analysis to determine their direction and magnitude of change. Extraction and assessment of the top five highest and lowest maximum and minimum temperatures were also done. Increasing trends of temperature anomalies for seasonal and annual timescales were observed for both Arusha and Kilimanjaro regions. Also, the increasing trends of warm and extreme warm days and nights and relatively increasing trends of cold and extreme cold days and nights were observed for both regions. The highest ever recorded temperatures since the establishment of the two stations were 36.3? C observed on 16th February 2011 and 38.6? C observed on 22nd February 2005 for Arusha and Kilimanjaro respectively. These results indicate that The last two decades have been characterized by enhanced warming, which is consistent with overall global temperature trend patterns as depicted in recent IPCC reports and the report of the State of Climate in Africa.
RESPOSTAS MORFOFISIOLÓGICAS DE PLANTAS DE SORGO, FEIJÃO-DE-CORDA E ALGODÃO SOB ESTRESSE SALINO

Propos-se, com este trabalho, avaliar os teores e a distribuicao de ions, alem de alguns parâmetros morfofisiologicos associados com a tolerância a salinidade em plantas de sorgo, feijao-de-corda e algodao. As plantas foram cultivadas em vasos contendo 15 kg de areia lavada, em condicoes de casa de vegetacao, e irrigadas com aguas com tres niveis de salinidade (condutividade eletrica de 0,5, 4,0 e 8,0 dS m-1). Apos 52 dias da semeadura foram medidas a area foliar e a producao de materia seca de folhas, caules e raizes. Foram tambem determinados: a suculencia foliar, a massa especifica foliar e os teores de Na+, Cl-, K+, Ca2+ e prolina. O algodao se diferenciou das duas outras especies em virtude de apresentar maior acumulo e retencao de Na+ e Cl- nas raizes, maior acumulo desses ions nos limbos foliares, menores alteracoes nos teores de K+ e aumento nos teores de prolina em resposta ao aumento da salinidade. O sorgo mostrou menores teores de ions potencialmente toxicos (Na+ e Cl-) nos limbos foliares, porem apresentou reducoes nos teores de K+ e Ca2+ na parte aerea. O elevado acumulo de Cl- nas folhas, associado a falta de outros mecanismos eficientes de protecao contribuiu, pelo menos em parte, para a maior sensibilidade do feijao-de-corda ao estresse salino.
Electronic Structure Study of Hydrogen Storage Materials

First principles electronic structure studies can provide, at a microscopic level, an understanding of the modification of the most fundamental properties of the matrix on hydrogen uptake such as metal-insulator transitions, magnetism, superconductivity, as well as a basic understanding of the hydrogen storage properties relevant to applications. To illustrating the latter point, we present an investigation of the properties of the hydrogen storage Nisubstituted LaNi5 intermetallic compounds. The eects of mono substitutions of Ni by 3 d elements (Mn, Fe, Co), an s p element of the 3d series, Cu, as well as by s p elements of the IIIA (Al) and IVA series (Si, Ge, Sn) for several substitution rates are presented. We discuss the trends observed in the electronic structure and the factors that control : the stability of the intermetallic and their corresponding hydrides and the maximum hydrogen absorption capacity. We found that besides the elastic eects associated to volume changes on Ni substitutions, chemical bonding eects and band filling eects play a crucial role in controlling the storage properties of the materials. We also analyze the eect of polysubstitutions at the Ni site in LaNi3.5Al0. 25Mn0.5Co0. 75, a composition close to that of an industrial compound of good electrochemical performances, and we discuss the results in light of thermodynamic and spectroscopic data.
Cytomegalovirus Infection in Kidney Transplant Recipients

Introduction: Present study examined the frequency of CMV infection during follow-up using quantitative nucleic acid amplification testing, the frequency of administration of infection prophylaxis, viremia and infection in kidney transplant recipients who underwent transplantation (TX) at the University Hospital Center Osijek. Materials and Methods: 107 kidney recipients who underwent transplantation in the period 20 October 2007 – 24 August 2016 were included. Demographic and clinical data, data about pre-transplantation CMV IgG test results of recipients and their donors, data about CMV prophylaxis, viremia, infection, and kidney transplant function were taken from medical records and analyzed. Results: 92.5% of kidney recipients and 86% of donors were CMV IgG positive before TX. 28% of recipients were CMV-DNA positive at some point after TX, none of whom received a transplant from an IgG negative donor. 89.7% of participants received CMV prophylaxis. Seven participants developed CMV disease, 2 of whom were not administered prophylaxis. Participants were tested for CMV-DNA once a year (median; min 0 max 6). CMV disease was marginally more frequent in those who did not receive valganciclovir prophylaxis (P = 0.066). Conclusion: It seems wise to enforce the administration of CMV prophylaxis and CMV-DNA testing in accordance with protocol, in order to detect viremia on time and to implement preemptive treatment, aiming at prevention of clinical manifestation of infection and preservation of graft function.
Trafficking and polarity control of the D6 PROTEIN KINASE from Arabidopsis thaliana

The polar transport of the phytohormone auxin is essential to the spatio-temporal control of plant development. Major players in this process are the polarly localized PIN-FORMED (PIN) proteins that mediate the cell-to-cell auxin efflux. D6 PROTEIN KINASE (D6PK) phosphorylates and co-localizes polarly with the PINs. In this thesis, I identify the mechanisms for D6PK trafficking and polarity control and evaluate their impact on PIN-mediated auxin transport.
Physico-Chemical Properties of Casein Micelles Concentrated by Membrane Filtration and Their Behavior in Acid Gelation

PHYSICO-CHEMICAL PROPERTIES OF CASEIN MICELLES CONCENTRATED BY MEMBRANE FILTRATION AND THEIR BEHAVIOUR IN ACID GELATION Ying Li Advisor: University of Guelph, 2014 Professor M. Corredig Membrane filtration is a widespread unit operation in dairy technology. In this study we investigated how ultrafiltration (UF) and diafiltration (DF) may affect the physico-chemical properties of the casein micelles and their functionality related to acid gelation. By concentrating by UF, the volume fraction of protein increased while maintaining the serum composition similar to that of the original milk. By using UF in combination with DF, the mineral equilibrium was modified. UF and DF retentates showed different behavior during heating, with the formation of different populations of non sedimentable complexes. Various combinations of heating temperature and time were investigated. Calcium solubilization as a function of pH was also affected, as demonstrated by measurements of buffering capacity and soluble calcium. The area of the maximum peak in buffering capacity observed at pH ~5.1, which is related to the presence of colloidal calcium phosphate, was significantly affected by casein volume fraction, but did not increase proportionally to casein concentration, even in the UF milk. This suggested the release of calcium phosphate even during concentration by UF. It was hypothesized that the changes in calcium equilibrium during UF and DF, as well as the formation of different types of soluble aggregates, during membrane
Graphic Design Effects on Consumer Online Purchase and Referral Intentions in Ghana’s Hospitality Industry: The Connections and the Mediating Role of Consumer Website Visit Satisfaction

: The Mehrabian and Russell's Stimulus‐Organism‐Response model was used to link and test the relationship between the predictor external variables (i.e., website artistic design (WAD), quality of information (QI)) as stimuli and the online purchase intention (PI) of consumers and referral intention (RI) as responses. The hedonic factor in this model was the satisfaction derived by consumers as a result of visiting the website. A test of the relationship between the WAD (stimulus), QI influenced by the design and text (organism) and the PI and RI (responses) was carried out using multiple regression analysis. Also, the Hayes’ Process macro tool‐pack of IBM‐SPSS (Version 25) was used to assess the potential mediation function of consumer website visit satisfaction (CWVS) (measured by likeability and comfort) on the relationship between WAD or QI and PI and RI. Findings showed a strong positive relationship between WAD and PI (r 2 = 0.550) and RI (r 2 = 0.491) and between QI and PI (r 2 = 0.421), but not RI (r 2 = 0.194). CWVS successfully mediated the relationships between WAD and PI, but not between WAD and RI. It also successfully mediated the relationships between QI and PI and RI. Results have shown that the satisfaction of consumers online was significantly dependent on WAD and QI and was needed for sustained PI and RI.
Broad-scale acoustic telemetry reveals long distance movements and larger home ranges for invasive lionfish on Atlantic coral reefs

Tracking studies for invasive lionfish (Pterois volitans and P. miles) in the Western Atlantic can provide key information on habitat use to inform population control, but to date have likely underestimated home range size and movement due to constrained spatial and temporal scales. We tracked 35 acoustically tagged lionfish for >1 yr (March 2018−May 2019) within a 35 km2 acoustic array in Buck Island Reef National Monument, St. Croix, US Virgin Islands (an area 10× larger than previous studies). Tracking lionfish at this scale revealed that home range size is 3−20 times larger than previously estimated and varies more than 8-fold across individuals (~48 000−379 000 m2; average: 101 000 m2), with estimates insensitive to assumptions about potential mortality for low-movement individuals. Lionfish move far greater distances than previously reported, with 37% of fish traveling >1 km from the initial tagging site toward deeper habitats, and 1 individual moving ~10 km during a 10 d period. Movement rates, home range size, and maximum distance traveled were not related to lionfish size (18−35 cm total length) or lunar phase. Lionfish movement was lowest at night and greatest during crepuscular periods, with fish acceleration (m s−2) increasing with water temperature during these times. Our results help reconcile observed patterns of rapid recolonization following lionfish removal, and suggest complex drivers likely result in highly variable patterns of movement for similarly sized fish occupying the same habitat. Culling areas ≥ the average lionfish home range size identified here (i.e. ~10 ha) or habitat patches isolated by ≥ ~180 m (radius of average home range) may minimize subsequent recolonization. If the shallow−deep long-distance movements observed here are unidirectional, mesophotic habitats may require culling at relatively greater frequencies to counteract ongoing migration.
Investigating Abnormal Disclosure Tone in Corporate Narratives: Evidence from an Emerging Market

2020) and redundancy (e.g. Dyer et al., 2017). Many prior studies show that management’s use of narrative disclosures and its attributes, like readability, tone, length, etc. is to provide users with additional information, helping them in assessing firm’s future performance and prospects (e.g., Aly et al., 2018; Boudt et al., 2018; Davis al., 2012; Del Gaudi 2019; Yekini, However, it is claimed that there are no direct rules to govern the disclosure of narrative information and they are not audited as well (except footnotes of financial statements). Thus, managers can have an opportunity to use these discretionary narrative disclosures opportunistically to bias and distort users’ perception towards the firm, which affects share prices and increase managers’ compensation. In this case, this biased reporting behavior is known as ‘Impression Management’ (Merkl-Davies and Brennan, 2007). Abstract: This study aims to investigate abnormal disclosure tone levels (i.e., extent of management’s tone manipulation) in narrative disclosures of earnings press releases of Egyptian firms. Net disclosure tone is measured by applying manual textual analysis using the financial-domain wordlist of Henry (2008). Then, abnormal disclosure tone is estimated using the model proposed by Huang et al. (2014). Results show that net disclosure tone in the narratives of earnings press releases of firms in all industry sectors tend to be positive and optimistic. In addition, while estimating abnormal disclosure tone levels, using Huang et al (2014) model, it is found that firms that are more profitable, larger, with less growth opportunities and more business segments tend to provide more positive and optimistic tone in their narrative disclosures. Moreover, results provide evidence for the existence of levels of abnormal tone in the narrative disclosures of earnings press releases (both upward and downward tone management), indicating the existence of some levels of tone manipulation by management in the Egyptian firms’ disclosures. Firms in the materials and the real estate sectors are found to have higher levels of abnormal disclosure tone in their earnings press releases. This study contributes to the existing literature, by providing insights regarding management’s use of abnormal tone (i.e., Tone management) in the narrative disclosures of Egyptian firms, which is an unexplored area yet in the Egyptian market or any other emerging market. The study provides an insight about the extent of management’s use of abnormal disclosure tone (i.e., Tone manipulation) in narrative disclosures of Egyptian firms’ earnings press releases. Thus, it attempts to notify users, especially non-professional investors, regarding the possible biases that could emerge in the corporate narratives due to management’s use of abnormal disclosure tone to bias their perceptions and judgments. Results also could be of importance to regulators and policy makers as the findings highlight and confirm the need of guidelines and regulations to guide the disclosure of corporate narrative information.
Analysis on the mechanism of enhancing insulin secretion by TRPM2 channel in a pancreatic β-cell

: It has been reported that the activation of the Ca 2+ -permeable transient receptor potential melastatin2 (TRPM2) channel enhances a pancreatic β -cell’s insulin secretion. Further, it increases the resting potential, and prolongs the burst duration of the pancreatic β -cell. However, the mechanism by which the TRPM2 channel activation enhances insulin secretion is unknown. Therefore, in this paper, using a mathematical model that represents the dynamics of the membrane potential, we investigate the reproducibility of the results obtained from physiological experiments, and reveal the mechanism of enhancing insulin secretion. We demonstrate that the TRPM2 channel activation prolongs the burst duration when the TRPM2 reversal potential is close to the value observed in the physiological experiments. This could be a plausible theoretical explanation of the experimental value of the TRPM2 reversal potential. In addition, we reveal that the TRPM2 channel activates the voltage-dependent and Ca 2+ -sensitive channels with large conductance, thereby inducing insulin secretion.
Identity Transformation Through Substance Use Disorder Recovery: Introducing the Six Stage Model

Narratives of substance use disorder recovery experience can provide useful qualitative conceptual categories and novel theories about the way in which recovery is experienced by individuals. This information can better inform definitions, concepts, and supports for recovery processes. The current study reviewed 30 written personal recovery biographies which were contained within student applications to the collegiate recovery program housed in the Center for Young Adult Addiction and Recovery at Kennesaw State University. Using grounded theory methodology, common benchmarks, or topographic recovery features were revealed involving the evolution of identity as an inter-negotiated process throughout the addiction and recovery biographies (Charmaz, 2008; Glaser & Strauss, 2017). From this, a six-stage theory model of recovery identity is formulated and explored. The biographies contained accounts from pre-substance use through the full embracement of a recovery identity. This model may help to serve recovery program managers to classify incoming individuals, identify and address needs, and facilitate innovative programming to meet such needs as they relate to the identity transformation process.
Wage Differentials And Educational Attainment In Germany. How Do Job Profiles Affect Earnings?

This paper presents the results of an empirical analysis on the issue of wage differentials occurring within education levels. The main purpose of the research is to investigate the extent to which job profiles, classified as routine and non-routine tasks can explain wage differentials within educational levels in Germany. Systematization of the literary sources and approaches for solving the problem of wage differentials indicates that in line with technological advancement witnessed over the past decades, earnings are largely determined by the nature of tasks carried out within the workplace. The relevance of this scientific problem decision is that educational systems have to keep up with advancing digitization and the rapidly changing labour market requirements. Investigation of the impact job profiles have on earnings, in the paper is carried out in the following logical sequence: firstly, a brief overview on previous research in the field is given, followed by an outline of the dataset analysed, proposed hypotheses, applied methodology and results concluding with a discussion. Methodological tools of the research methods were descriptive statistics along with OLS regression techniques. Based on German cross-sectional employee survey data from 2018 two hypotheses are tested by classifying 23 selected work activities into routine and non-routine tasks linked to the highest education level attained. In accordance with the German education system four educational levels are specified: no occupational degree, in-company or school-based vocational training, advanced vocational training degree and university degree. The results indicate that non-routine activities are on average remunerated at a higher rate compared to routine activities and non-routine analytical work is paid at a higher rate than non-routine craftmanship. Additionally, higher wages for computer assisted work activities is found. The OLS regression model results confirm both hypotheses implying increasing returns to educational attainments resulting in larger hourly pay and higher pay for those performing non-routine tasks. Pursuant to the traditional Mincer human capital approach on returns to schooling the research empirically confirms higher wages for employees completing advanced vocational training and those holding a university degree. The results of the research can be useful for policymakers in the education sector, fostering and improving analytical, data literacy and organizational skills.
Revisiting the Role of Academic Advising in Equitably Serving Diverse College Students

It has been more than a decade since Museus and Ravello analyzed the roles that culturally engaging academic advisors play in producing equitable outcomes among racially diverse student populations. Their study highlighted the importance of humanized, holistic, and proactive advising in effectively serving students of color in particular. In this essay, one of the original authors discusses how a decade of research has built on this earlier analysis and summarizes evolving insights about the role of culturally engaging advising in supporting students of color. The article concludes with implications for future research, policy, and practice aimed at more equitably serving diverse populations.
Fostemsavir in Heavily Treatment-Experienced Individuals Living with HIV-1: Insights from the Phase 3 BRIGHTE Study

Fostemsavir (RukobiaTM, ViiV Healthcare, Research Triangle Park, NC), a prodrug of the first-in-class attachment inhibitor temsavir, was developed to provide a much-needed new therapeutic option for heavily treatment-experienced (HTE) people living with HIV-1 (PLWH) who are unable to form a suppressive regimen from remaining viable antiretroviral (ARV) agents because of multidrug resistance, contraindications, prior intolerance, or other safety considerations [1-4]. Effective treatment for this vulnerable population can be complicated by other challenges in addition to multidrug resistance, including low CD4+ T-cell counts, comorbidities, psychosocial factors, and non-adherence to complex regimens [4-9]. Regulatory approval of fostemsavir was based on results from the phase 3 BRIGHTE study (ClinicalTrials.gov, NCT02362503) showing that, in HTE adults who were failing their current ARV regimen with limited remaining treatment options, fostemsavir combined with optimized background therapy (OBT) was generally well tolerated and resulted in a distinctive trend of increasing virologic response rates (by intention-to-treat–exposed [ITT-E] Snapshot and observed analysis) and increases in CD4+ T-cell counts through 96 weeks [1,4]. In this commentary, we dig deeper into the rationale for the BRIGHTE study design, expand upon the remarkable patterns of virologic and immunologic response observed in BRIGHTE, and consider how these patterns may be related to the unique mode of action of fostemsavir (temsavir). The BRIGHTE Clinical Study Design was Appropriate for HTE PLWH
