Published: January 2024

In factorial experiments conducted under randomized block design, the multiple linear regression model fitting can be performed under different combinations of the quantitative levels of the two factors and the number of replications. To determine the best combination, considering the same number of levels per factor and the same number of experimental units, it was concluded through a simulated data study that the quality of the fit increases when regression is performed in experiments with fewer combinations of levels (treatments) and more replications. Therefore, if linearity is expected, using four treatments evaluated in a 2 × 2 factorial design for model fitting is recommended. Otherwise, nine treatments evaluated in a 3 × 3 factorial design are recommended. All of this is for experiments with coefficients of variation of 20%.

Are Electric-field-driven Magnetohydrodynamic Simulations of the Solar Corona Sensitive to the Initial Condition?
Authors: Barnes Graham , Hayashi Keiji , Gilchrist S. A. 
Published: January 2024

Abstract
Magnetohydrodynamic (MHD) simulations of the solar corona are often started from a potential field initial condition, which may be far from the true state of the coronal magnetic field. To test the sensitivity of the simulations to the initial condition, an electric-field-driven MHD code was initiated from three different initial conditions: the commonly used potential field, a nonlinear force-free field (NLFFF) extrapolation, which is believed to be a better representation of the true coronal magnetic field, and a purely vertical field. After relaxation, the magnetic field in the MHD simulations was compared. It was found that there is a tendency for all of the initial conditions to converge to a similar connectivity, particularly in areas of strong fields that are not close to the boundary, suggesting that the final state of the simulation is not particularly sensitive to the initial condition. The relaxed solution more closely resembles the NLFFF initial condition than the other initial conditions, but still exhibits substantial differences from it.
4FGL J1318.2+6754: A Long Orbital-period Redback Candidate
Authors: Lin Jie , Chen Hailiang , Wang Bojun , Xu Renxin 
Published: January 2024

Abstract
By combining the Fermi catalog and the single-lined spectroscopic binaries of Gaia Data Release 3 (DR3), we report a new candidate redback millisecond pulsar binary, which is recommended as a target for radio telescopes to detect pulsed signals. Using TESS data in the T band spanning over 4 yr, we find a period of ∼4.13 days, which is consistent with the radial velocity solution of the Gaia DR3 and optical spectroscopy from the LAMOST telescope. The light curve in the T band reveals periodic modulation of low amplitude that is a characteristic feature of the heating of the photosphere of a nondegenerate low-mass stellar companion by the pulsar wind. The nondegenerate companion is a bright (G = 11.96), slightly metal-poor ([Fe/H] = − 0.55), G-type main-sequence star (T
eff = 5891 K;

;

R = 1.356R
⊙). This orbital period of 4.13 days would be the longest one for known redback candidates, which could hardly be understood for its formation in the standard recycling scenario due to its large Roche-lobe radius (≫the radius of the G-type main-sequence star). It is proposed here that this candidate redback millisecond pulsar binary could be created via accretion-induced collapse of an oxygen–neon–magnesium white dwarf.

Published: January 2024

Aluminium matrix composite (AMC) materials play an important role in the field of automobile and aerospace industries due to their excellent properties. In this research, aluminium alloy (AA7075) was reinforced with alumina (Al2O3) particles to improve their hardness and tribological behaviour of the base alloy. Four composites were prepared by varying the content (4, 8 and 12 wt.%) of Al2O3 particles through the stir casting technique. The surface morphology of the proposed composites ensured the uniform distribution of Al2O3 particles into the matrix alloy. The hardness of the composite was measured using a Brinell hardness tester and the maximum value of hardness was found in the AA7075 - 8 wt.% Al2O3 composite. Hence, a tribological investigation was carried out on this AA7075 - 8 wt.% Al2O3 composite. Load (P), sliding speed (V) and sliding velocity (D) were taken as the wear parameters for conducting the experiments. A Technique for Order Preference by Similarity to Ideal Preferred Solution (TOPSIS) approach has been applied to find out the optimal conditions of parameters to obtain the lowest wear rate (WR) and the co-efficient of friction (COF). The results showed that the lowest WR and COF was obtained at ‘P’ of 15 N, ‘V’ of 1 m•s-1 and ‘D’ of 1000 m•s-1. ANOVA results revealed that ‘P’ is the factor with the most significant contribution (38.36%), followed by ‘D’ (28.32%). The worn surface morphology of the confirmation experiment specimen was investigated by SEM and the wear mechanism was reported.

Abstract
Epigenetic regulation plays a crucial role in the development and progression of cancer, including the regulation of antitumor immunity. The reversible nature of epigenetic modifications offers potential therapeutic avenues for cancer treatment. In particular, histone deacetylase (HDAC) inhibitors (HDACis) have been shown to promote antitumor T cell immunity by regulating myeloid cell types, enhancing tumor Ag presentation, and increasing expression of chemokines. HDACis are currently being evaluated to determine whether they can increase the response rate of immune checkpoint inhibitors in cancer patients. Although the potential direct effect of HDACis on T cells likely impacts antitumor immunity, little is known about how HDAC inhibition alters the transcriptomic profile of T cells. In this article, we show that two clinical-stage HDACis profoundly impact gene expression and signaling networks in CD8+ and CD4+ T cells. Specifically, HDACis promoted T cell effector function by enhancing expression of TNF-α and IFN-γ and increasing CD8+ T cell cytotoxicity. Consistently, in a murine tumor model, HDACis led to enrichment of CD8+ T cell subsets with high expression of effector molecules (Prf1, Ifng, Gzmk, and Grmb) but also molecules associated with T cell exhaustion (Tox, Pdcd1, Lag3, and Havcr2). HDACis further generated a tumor microenvironment dominated by myeloid cells with immune suppressive signatures. These results indicate that HDACis directly and favorably augment T cell effector function but also increase their exhaustion signal in the tumor microenvironment, which may add a layer of complexity for achieving clinical benefit in combination with immune checkpoint inhibitors.
analysis of debt sustainability in Brazil
Authors: Ferreira-Filho Helder Lara 
Published: January 2024

Resumo: Este artigo tem como objetivo discutir a sustentabilidade da dívida da economia brasileira, que está sob escrutínio desde 2013. As economias emergentes podem enfrentar instabilidade com balança de pagamentos ou aumento da inflação devido a uma possível desvalorização cambial. Assim, foram realizadas simulações prospetivas da dinâmica da dívida bruta utilizando dados disponíveis até 2023. Até 2040, sob as expectativas do mercado e certos pressupostos, a dívida bruta não parece explosiva. A Dívida Bruta do Governo Geral (DBGG) tende a aumentar no curto prazo, estabilizando-se no médio e longo prazo. Contudo, não é uma situação confortável, especialmente considerando que os níveis de DBGG estão acima dos países emergentes e dada a possibilidade de choques adversos nas variáveis ​​mais relevantes sobre a dinâmica da dívida. A combinação de “r – g” deve melhorar para que o Brasil tenha uma trajetória de dívida mais benigna.
Palavras- chave: Sustentabilidade da dívida e economia brasileira

Abstract: This article aims to discuss the debt sustainability for the Brazilian economy, which has been under scrutiny since 2013. Emerging economies may face instability with balance of payments or rising inflation due to a possible currency devaluation. Thus, prospective simulations of gross debt dynamics were conducted using data available up to 2023. Until 2040, under market expectations and certain assumptions, gross debt does not seem explosive. General Government Gross Debt (GGGD) tends to rise in the short term, stabilizing in the medium and long term. However, it is not a comfortable situation, especially considering that GGGD levels are above those of emerging countries and given the possibility of adverse shocks in the most relevant variables regarding debt dynamics. The combination of “r – g” should improve for Brazil to have a more benign debt trajectory.

Hubungan Antara Self Disclosure dengan Interpersonal Trust pada Pasangan Dewasa Awal yang Menjalani Long Distance Relationship (LDR)
Authors: Septiani Alvina Tri , Kusumiati Ratriana Yuliastuti Endang 
Published: January 2024

Long distance relationship (LDR) is a form of romantic relationship where two people are separated by physical distance which makes it difficult for both to establish closeness within a certain period. Of course, living in a long-distance relationship is not an easy thing if there is no self-disclosure and interpersonal trust in the relationship. Openness is one of the factors that play an important role in forming interpersonal trust. Openness arises because of the trust between partners and this encourages them to feel comfortable in sharing all kinds of information about themselves to their partners. The purpose of this study is to determine the relationship between self-disclosure and interpersonal trust in early adult couples who undergo long-distance relationships. This study uses a correlational quantitative approach with 120 respondents. The sampling technique in this study used accidental sampling. The results of the correlation coefficient analysis obtained are 0.837 and the significance value of the correlation r is 0.000 (p <0.05). The effective contribution between self-disclosure and interpersonal trust is 70%. So it can be concluded that there is a positive relationship between self-disclosure and interpersonal trust, meaning that the higher the self-disclosure, the higher the level of interpersonal trust in early adult couples who undergo long-distance relationships, and vice versa

Pertarungan Makna Atas Pernyataan Cawe-Cawe Presiden Jokowi Mengenai Pemilu 2024 di Media Indonesia
Authors: Simamora Jumadal , Rusadi  Udi 
Published: January 2024

The mass media has an important role as a means to reach a wide audience that can influence public opinion in society. Therefore, the media is a social institution that is contested to obtain and win power. Text is a form of ideological practice, language, writing and choice of words that are understood to carry ideological meanings that are used to win public support. In a meeting with the editors-in-chief of mass media and content creators, President Jokowi stated that he would participate in the 2024 elections to ensure that the elections take place safely and smoothly. President Jokowi's statement that he will chat in the 2024 Presidential Election has received pros and cons and has been interpreted differently by the public. The purpose of this study is to find out how the battle for meaning is being carried out by Media Indonesia regarding the statements of President Jokowi's cawe in the 2024 election in the headline news. This study uses a critical paradigm using a political economy media approach. The method used is Halliday's social discourse analysis method which is based on three concepts, namely, the field of discourse, the involvement of discourse and the mode of discourse. Based on the analysis carried out, in its reporting, Media Indonesia chose sources who were dominant against President Jokowi's cawe-cawe statements. Cawe-cawe is interpreted as the President's non-neutrality in the 2024 presidential election, a setback to democracy and as scaring the people.
