Late stages of stellar evolution. II: Mass loss and the transition of asymptotic giant branch stars into hot remnants

We have computed the transition of asymptotic branch giants of 0.8 and 1.0 M/sub sun/ into remnants of 0.565, 0.553, and 0.546 M/sub sun/ by means of mass loss which removed the stellar envelopes in about 10/sup 3/ yr. The remnants were then evolved across the H-R diagram to the white dwarf configuration and their relevance for central stars of planetary nebulae studied. From the temporal evolution of these models we determined lower limits for mass and luminosity of central stars of approx.0. 55 M/sub sun/ and approx.2500 L/sub sun/.
Non-trivial magnetic order in URu2Si2?

We have searched for the hidden multispin order parameters that have been proposed to explain the weak ordered moment observed in the heavy-fermion superconductor URu2Si2. Since the exotic spin order is predicted to cause broken-symmetry Bragg peaks that develop rapidly with applied magnetic field, we have measured their strength in fields up to 8 T, for which a large easily observable moment is predicted. The Bragg neutron scattering is found to decrease rather than increase when a field is applied along the easy tetragonal c-axis, while there is no change for a field at right angles. The results rule out the proposed symmetric multispin order parameters. The zero-field transition is found to exhibit critical softening of the spin gap and a cusp in the susceptibility at TN, as expected for the ordering of magnetic dipoles.
Translanguaging as an Inclusive Pedagogical Practice in Early Education Classes

Using students’ full linguistic resources in classes has always been controversial. Some researchers still adopt the monolingual ideology, while others see that incorporating students’ L1s can help in many aspects of teaching practices. This has led to several multilingual pedagogical practices, one of which is translanguaging. The latter has been theorized as a pedagogical resource for building and promoting students’ knowledge and inclusion. This study examines translanguaging as an inclusive strategy in early education. The participants are teachers and students from three preschool classes. This study aims to explore to what extent translanguaging helps engage students more in their classroom activities and boosts their well-being in their classes. Then, teachers’ perceptions of translanguaging as a pedagogical practice were investigated. Both classroom observations and interviews were used as research instruments in this study. The results indicated that translanguaging helps significantly in engaging young learners in their classroom activities and increases participation and fun during learning activities. Concerning the teachers’ perceptions, although they see that translanguaging creates more fun and engagement, they are still reluctant to embrace and employ it in their daily teaching practice for various pedagogical and personal reasons.
MYCOPARASITISM ACTIVITY OF TRICHODERM HARZIANUM ASSOCIATE WITH CHITINASE EXPRESSION AGAINST GANODERMA BONINENSE

The filamentous fungus Trichoderma is an important fungus due to its biocontrol properties. This study was conducted on mycoparasitism activity of Trichoderma harzianum T32 against Ganoderma boninense upm001 on the basis of Potato Sucrose Agar (PSA) under the scanning electron microscope observation or cell wall degrading enzyme of chitinase gene expression by reverse-transcriptase (RT) PCR. The mycoparasitism process of Trichoderma harzianum T32 showed the coiling or killing of the Ganoderma boninense upm001 in PSA media. Deformity and shrinkage of Ganoderma mycelia was also observed under the scanning microscope in presence of Trichoderma. The RT-PCR profile showed that chitinase gene was expressed during the mycoprasitism activity in T. harzianum against G. boninense. It could be concluded that chitinase gene was an important element in process of biocontrol activity of Trichoderma as the gene was expressed against G. boninense.
Construction and Validation of a Novel Immune Checkpoint-Related Model in Clear Cell Renal Cell Carcinoma

Background With the highest mortality and metastasis rate, kidney renal clear cell carcinoma (KIRC) is one of the most common urological malignant tumors and not sensitive to chemotherapy and radiotherapy. Immunotherapy, which proves to be effective and a big progression, such as PD-1/PD-L1 inhibitors, is not sensitive to all KIRC patients. To predict prognosis and immunotherapy response, a novel immune checkpoint gene- (ICG-) related model is essential in clinics. Methods From the public database-downloaded dataset, a novel ICG-related model for predicting prognosis and immunotherapy response in KIRC patients was built up and verified with R packages and Cox regression analysis. The Kaplan-Meier curve was plotted. Results 39 ICGs were identified to have different expression in KIRC patients and enriched in immune-related biological pathways and activities. Three ICGs (CTLA4, TNFSF14, and HHLA2) were screened to generate KIRC-ICG model. The KIRC-ICG model was verified to be effective. With conducting KIRC-SYS model, KIRC-ICGscore was verified to be an independent factor regardless of age, gender, stage, grade, and TNM stage. Compared to the ICG-low subgroup, the ICG-high subgroup had more immune activities. KIRC-ICGscore was significantly positively correlated with the expression of Treg markers. KIRC-ICG model could also be reliable to predict immunotherapy response. Conclusion The KIRC-ICG model was reliable to predict prognosis and immunotherapy response for KIRC patients and could be an independent factor regardless of clinical characteristics.
Twisted flag varieties of trialitarjan groups

For (A, σ) a central simple algebra of even degree with orthogonal involution, we present a method for constructing isotropic right ideals in the even Clifford algebra (C 0(A, σ)σ) from isotropic right ideals in (A, σ). We then use this construction to fully describe the twisted flag varieties associated to algebraic groups of type D 4 (including the trialitarian groups).
The impact of African agriculture production on bank stability through bank risk and profit

The African farming sector suffers from insufficient finance. Climate changes and socio-political issues hold down the required production level while food on the continent is still inadequate, with more vulnerable people on the one side. On the other side, credit institutions need reasons and guarantees to raise their risk-taking level (financial benefits). Then, this study tries to conciliate those two sides with new shreds of evidence by demonstrating the short and long-run effects of agricultural production on bank sustainability in 40 Sub-Saharan African countries. The study used different agro-production factors (Food and Cereal production factors), bank stability proxies (Liquidity Ratio, NPLs, LLRs), and bank profitability proxies (ROA and ROE). The GMM, DFE, and FMOLS models were used for short (with the 2010-2019 dataset) and long-run analysis (with the 1970-2018 dataset). The results demonstrated that agricultural production increases bank stability and profitability but reduces bank risks. The study concludes that farming finance increases agro-production and stabilizes banks (win-win). Governments, via central banks, should encourage commercial banks to increase bank risk-taking levels to sustain their banking system, increase farming production, and improve food security.
Journal of Animal and Poultry Production

The current study was carried out in the Animal Production Research Station, Sakha Kafr El-Sheikh Egypt belonging to Animal Production Research Institute (APRI Animal Production Research Institute (APRI), EGYPT. Two experiments were carried out to evaluate the effects of dietary amino acid supplementation (Methionine or lysine) in the diet of local chicken breed AL-SALAM on the performance and serum chemistry. The control group contained 0.2 g lysine / kg diet and 0.2 g methionine / kg diet. Lysine levels were 1.12, 1.37 and 1.6 g lysine / kg diet. Methionine levels were 0.60, 0.64 and 0.68 g methionine / kg diet. We found that when adding access amino acid lysine to the diet at level (1.6%) or adding access methionine at levels (0.64 % and 0.68 %) increased daily body weight gain significantly, compared with the control group. Lysozyme’s activity was increased when adding access amino acid methionine (0.64 and 0.68%M) then levels (.12%L, 1.37%L, 1.60%L, and 0.60%M, respectively) than the control group. Relative economic efficiency was better when adding access levels (1.60%L or 0.64 and 0.68%M), than other groups. Finally, we suggest adding access lysine with levels 1.60 (%) or access methionine with levels 0.64 and 0.68 % to rations of local poultry breeds from 14 days to reach market weight to reveal the best economic profit gain and to promote the economic efficiency, with reasonable cost.
Numerical Simulations of Astrophysical Jets from Keplerian Disks. II. Episodic Outflows

We present 2.5-dimensional time-dependent simulations of the nonlinear evolution of nonrelativistic outflows from Keplerian accretion disks orbiting low-mass protostars or black holes accreting at sub-Eddington rates. The gas is ejected from the surface of the disk (which is a fixed platform in these simulations) into a cold corona in stable equilibrium. The initial magnetic field lines are taken to be uniform and parallel to the disk axis (z-axis). Because of the gradient force in the nonlinear torsional Alfvén waves generated by the rotor at the footpoints of the field lines, the initial magnetic configuration opens up in a narrow region on the disk's surface located at ri < r < 2ri with ri being the innermost radius of the disk. Within this narrow region, a wind is ejected from the field lines that have opened to less than the critical angle (≃60°), as expected from the centrifugally driven wind theory. Our simulations show that the strong toroidal magnetic field generated recollimates the flow toward the disk's axis and, through magnetohydrodynamic (MHD) shocks, produces knots. The knot generation mechanism occurs at a distance of about z ≃ 8ri from the surface of the disk. Knots propagate down the length of the jet at speeds less than the diffuse component of the outflow. The knot generator is episodic and is inherent to the jet.
THE SYSTEMIC RISK IN THE GULF COOPERATION COUNCIL COUNTRIES’ EQUITY MARKETS AND BANKING SECTORS: A DYNAMIC COVAR APPROACH

This paper examines the systemic risk and its spillover between banking sectors of the Gulf Cooperation Council (GCC) region using the conditional value-at-risk framework. We construct country-specific banking indices using 11 large banks in the region that are systemically important (SIB). We report evidence of systemic risk spilloversfrom SIBs to the broad-based GCC market indices. The incremental tail spillovers are statistically significant for other domestic banks’ tail risk and inflate the systemic risk of cross-country GCC banks.
Heterogenous impact of monetary policy on the Philippine rural banking system

This paper shows the differential impact of monetary policy on the lending behavior of rural banks, with the bank lending channel being operational in small rural banks. While big rural banks are able to protect their lending portfolio from contractionary monetary policy by the size of their balance sheet, small rural banks with less diversified funding portfolio cannot. Moreover, highly capitalized rural banks are more inclined to protect their capital than expand their lending portfolio, following monetary tightening and higher capital requirement. The insignificance of gross domestic product (GDP) growth may reflect weakness in effective loan demand and lack of diversification that could have also impinged on the earning capacity of rural banks, as supported by initial estimates on the drivers of rural bank profitability. The finding on heterogeneous effects of monetary policy on rural banks has a secondary implication of lending credence to the principle of proportionality embodied in the BSP’s bank regulatory framework.
Latent Heating and Cooling Rates in Developing and Nondeveloping Tropical Disturbances during TCS-08: Radar-Equivalent Retrievals from Mesoscale Numerical Models and ELDORA*

AbstractLatent heating and cooling rates have a critical role in predicting tropical cyclone formation and intensification. In a prior study, Park and Elsberry estimated the latent heating and cooling rates from aircraft Doppler radar [Electra Doppler Radar (ELDORA)] observations for two developing and two nondeveloping tropical disturbances during the Tropical Cyclone Structure 2008 (TCS-08) field experiment. In this study, equivalent retrievals of heating rates from two mesoscale models with 1-km resolution are calculated with the same radar thermodynamic retrieval. Contoured frequency altitude diagrams and vertical profiles of the net latent heating rates from the model are compared with the ELDORA-retrieved rates in similar cloud-cluster regions relative to the center of circulation.In both the developing and nondeveloping cases, the radar-equivalent retrievals from the two models tend to overestimate heating for less frequently occurring, intense convective cells that contribute to positive vorticity.
The Profile Sampler

We consider frequentist inference for the parametric component θ separately from the nuisance parameter η in semiparametric models based on sampling from the posterior of the profile likelihood. We prove that this procedure gives a first-order–correct approximation to the maximum likelihood estimator and consistent estimation of the efficient Fisher information for θ, without computing derivatives or using complicated numerical approximations. An exact Bayesian interpretation is established under a certain data-dependent prior. The sampler is useful in particular when the nuisance parameter is not estimable at the rate, where neither bootstrap validity nor general automatic variance estimation has been theoretically justified. Even when the nuisance parameter is consistent and the bootstrap is known to be valid, the proposed Markov chain Monte Carlo procedure can yield computational savings, because maximization of the likelihood is not required. The theory is verified for three examples. The methods are shown to perform well in simulations, and their practical utility is illustrated in two data analyses.
Forkhead Box P3 (FOXP3) Gene Polymorphisms Association with its Serum Levels in Egyptian Vitiligo Patients

Background: Vitiligo is an autoimmune disorder characterized by loss of pigmentation from the skin due to selective destruction of cutaneous melanocytes. Its pathogenesis is linked to regulatory T-cell (Treg) dysfunction. Forkhead box P3 (FOXP3) is a specific Treg marker and a master regulator of its activity. Objective: The aim of this study was to examine the relationship between serum levels of FOXP3 in Egyptian vitiligo patients and single-nucleotide polymorphisms (SNPs) at two distinct loci (rs3761548) A/C and (rs2232365) A/G situated in the promoter region of the FOXP3 gene. Patients and methods: The case control study comprised 50 untreated vitiligo patients who attended the dermatology clinic at Benha University Hospitals, and 30 age- and sex-matched healthy controls. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to identify FOXP3 gene polymorphism, and a FOXP3 enzyme linked immunosorbent assay (ELISA) was used to assess the quantity of FOXP3 in the blood. Results: Highly significant difference (P <0.001) was found between patients and control groups in rs3761548 A/C, rs2232365 A/G and combined genotypes as well as in serum FOXP3 levels measurements. The SNPs (rs3761548 and rs2232365) of FOXP3 gene were significantly associated with susceptibility to vitiligo. Conclusion: In our sample of Egyptian patients, analysis of FOXP3 protein levels and its gene SNPs demonstrates their substantial correlation with vitiligo. As the number of mutant alleles rises, the risk of vitiligo tends to follow. Patients with vitiligo have lower blood levels of FOXP3, which is indicative of the disease's pathophysiology and progression.
Negative corona in air at atmospheric pressure due to a voltage impulse

This article presents a numerical modeling of a negative corona caused by an overvoltage pulse (∼250%), in a point-to-plane electrode system. The field value applied to the cathode is high, thus, the numerical simulation described in this article attempts to show that the field-effect emission can be responsible for the ignition of the corona and for its first stage of development, while the positive-ion bombardment is responsible for sustaining the discharge during the current decay phase. A time-dependent enhancement factor is introduced in the classical Fowler–Nordheim relationship in order to model the switch on of some emissive site at the cathode surface. Preliminary experiments were carried out in order to better understand the ignition and development of the corona. The role of the field-effect emission is underlined and the dimension of the corona is optically determined. The negative corona current pulse and its associated emitted UV light are computed and compared to experimental results.
INFRARED SPECTRA OF DUST AGGREGATES IN COMETARY COMAE: CALCULATION WITH OLIVINE FORMED BY EXOTHERMIC CHEMICAL REACTIONS

Mineralogy of cometary dust plays an important role in understanding the formation and evolution of comets, the most primitive objects in the solar system. A correct interpretation of infrared spectra observed for cometary comae is the key to success in identifying mineral constituents of cometary dust. However, the composition, size, and structure of cometary dust might have been misinterpreted in previous studies, owing to a lack of a unique solution in their analyses of infrared spectra. We present a semianalytic method to compute infrared spectra for large aggregate particles consisting of submicrometer size grains inclusive of crystalline minerals. The method is applied to calculate the absorption cross section of primordial interstellar dust that is processed in a cometary coma. The processed interstellar dust is here modeled as clusters of concentrically stratified spheres consisting of an organic refractory outer mantle, an olivine inner mantle, and an amorphous silicate core. Spectral variations in the absorption cross sections for porous aggregates with a forsterite layer exhibit noticeable features at all the wavelengths where mineral features are observed in the infrared spectra of cometary comae. In contrast, the observed infrared spectra of cometary comae show no evidence for the presence of fayalite in cometary dust. Infrared observations of cometary comae are consistent with the picture that cometary nuclei contain primordial interstellar dust as well as interstellar ices.
Some Selection Problems Involving Folded Normal Distribution

Consider k independent normal populations with unknown means and a common unit variance and let a better population be defined to be one with a larger absolute value of the mean. The problem of selecting the t best of k populations is considered; the common number of observations from each population is determined so that the probability of a correct selection is not less than a specified quantity whenever the parameters lie in a pre-assigned parametric sub-space. A procedure for this problem is proposed and tables and bounds for probability of a correct selection are provided; some properties of the proposed procedure are also discussed. The problem of selecting a small non-empty subset containing the best population is also considered; a procedure is proposed and the constant involved in the procedure is determined so that the probability of a correct selection is not less than a specified quantity. The expected size of the selected subset is derived and its supremum obtained. Two secondary problems for.
Determinants of Micro, Small, and Medium Enterprises: The Case of an Emerging Economy in Indonesia

The covid-19 pandemic has worsened Indonesia’s economic situation. Most households have tried to survive by running their own business because they have just been fired from their latest company. Unfortunately, this business cycle forced families to reduce production costs due to less aggregate product demand. Many of them collapsed, and fewer survived. The condition of natural selection is to make government create a proper policy to prevent bad things happen in the future since MSME is categorized as an informal sector with many forms, such as culinary, services, and education. Most empirical studies show that the informal sector contributes more than 60% to Indonesia economic outcome. The aggregate demand for MSME products is only consumed by 20% of below-income group households. This study aims to analyse the effect of input factor on MSME productivity, proving that labour and capital investment is determinants for the extreme resilience of MSME in Indonesia. It used secondary data from 2016 to 2020 about the MSME sector in Indonesia and the Ministry of Cooperation using a proxy of MSME productivity and the MSME export ratio of total exports of all economic sectors. This research was then analyzed using the Linear Regression with Ordinary Least squares with STATA 14. The results showed that the labour and capital investment in the MSME sector had a positive and significant effect on the productivity and export ratio of MSMEs. T-statistics and F-statistics indicate both are higher than T and F table (p-value < 0,05). The regression model also does not suffer from classical assumption tests such as heteroskedasticity, multicollinearity, and autocorrelation.
Heat ameliorative effects of rumen protected niacin supplementation in lactating Surti buffaloes

Niacin may cause evaporative thermolysis through cutaneous hyperemia, vasodilation, increased sweating rate and decreased skin temperature. It is antilipolytic and can improve metabolic responses. Heat stress ameliorative effects of rumen protected niacin (RPN) supplementation in lactating Surti buffaloes during summer has been investigated in present study. Fourteen lactating Surti buffaloes were divided into two groups (Control-T1, N=7; RPN-T2, N=7). T2 (RPN) group was supplemented with RPN 6 g/ animal/ day in two divided dose for 4 weeks. Meteorological, physiological, sweating rate and skin temperature parameters, milk yield and composition were recorded at weekly intervals. Hematological and biochemical analytes were analyzed at week 1 and 4. RPN supplementation decreased physiological parameters RT, RR and TT; increased (P≤0.05) sweating rate and decreased (P≤0.05) skin surface temperature; increased (P≤0.05) TEC, Hb, HCT, LYM and decreased (P≤0.05) GRAN in hematological profile; increased (P≤0.05) glucose and decreased (P≤0.05) cholesterol, triglyceride, NEFA and BHB among biochemical metabolites and increased (P≤0.05) GSH and SOD and decreased (P≤0.05) LPO in oxidative stress profile. RPN supplementation increased milk yield and milk fat. It was concluded that supplementation of rumen protected niacin in lactating Surti buffaloes increases sweating rate, reduces oxidative stress and increases milk fat and milk production.
Investigating Modality in Policy Texts: Corpus-assisted Critical Discourse Analysis of Modals in the 2030 Agenda for Sustainable Development

The primary goal of this research is to investigate the role of modal resources in policy discourse. To this end, the 2030 Agenda for Sustainable Development, issued by the United Nations member states in 2015 representing a global comprehensive plan for the transformation of the world, is critically analyzed with a particular focus on examining the frequency and strategic functions of modal verbs in conveying certain interpersonal meanings that contribute to the influential delivery of messages in the Agenda. The corpus of the study comprises the full transcript of the 2030 Agenda; a corpus-assisted critical discourse approach was adopted for data analysis. The theoretical framework relies upon Fairclough’s dialectical-relational approach (2015) in combination with the corpus linguistics tool AntConc
