Published: November 2021

Abstract
X-ray quasi-periodic eruptions (QPEs) were discovered recently in active galaxies with an unknown driving mechanism. Under the assumption that QPEs are caused by star–disk collisions, we adopt full relativistic method and show that both the orbital parameters of the star and also the mass and spinning of the massive black hole (MBH) can be revealed by using the time of arrival (TOA) of the QPEs. By applying the model to the observed QPEs of GSN069, we find that the star is in a near-circular orbit (

. The alternative short and long recurring time of the QPEs of GSN069 can be well explained by the small eccentricity and the orbital precession of the star. We find that the QPEs of GSN069 are possibly driven by a striped stellar core colliding with accretion disk after a partial tidal disruption event around the MBH. For GSN069-like galaxies, if continuous X-ray monitoring of QPE events can be accumulated with uncertainties of TOA ≲100–150 s, the spin of the MBH can be constrained by fitting to QPEs. Our results show that the timing of QPEs can provide a unique probe for measuring the spinning of the MBH and tests of the no-hair theorem.
Formation of a Solar Filament by Magnetic Reconnection, Associated Chromospheric Evaporation, and Subsequent Coronal Condensation

Abstract
We present the first observation of a solar filament formed by magnetic reconnection, associated chromospheric evaporation, and subsequent coronal condensation. Driven by shearing motion during flux emergence, a sequential tether-cutting reconnection process occurred and resulted in an M1.3 confined flare accompanied by the formation of a sigmoid structure. It is found that the flare had conjugate compact footpoint brightenings, which correspond to the footpoints of the sigmoid. Furthermore, observational evidence of explosive evaporation is well diagnosed at the conjugate footpoint brightenings in the impulsive phase of the flare. After the flare, continuous cool condensations formed at about the middle section of the sigmoid and then moved in opposite directions along the sigmoid, eventually leading to the formation of the filament. These observations suggest that magnetic reconnection can not only form the magnetic field structure of the filament but also heat the chromospheric footpoints during their formation and drive chromospheric evaporation. As a result, the heated chromospheric plasma may be evaporated into the magnetic field structure of the filament, where the accumulated hot plasma might suffer from thermal instability or nonequilibrium, causing catastrophic cooling and coronal condensation to form the cool, dense material of the filament. This observation lends strong support to the evaporation–condensation model and highlights the crucial role of magnetic reconnection in forming both the magnetic field structure and the cool, dense material of the filaments.

Abstract
IFN-γ–inducible protein 16 (IFI16) recognizes viral DNAs from both nucleus-replicating viruses and cytoplasm-replicating viruses. Isoform 2 of IFI16 (IFI16-iso2) with nuclear localization sequence (NLS) has been studied extensively as a well-known DNA sensor. However, the characteristics and functions of other IFI16 isoforms are almost unknown. Here, we find that IFI16-iso1, with exactly the same length as IFI16-iso2, lacks the NLS and locates in the cytoplasm. To distinguish the functions of IFI16-iso1 and IFI16-iso2, we have developed novel nuclear viral DNA mimics that can be recognized by the nuclear DNA sensors, including IFI16-iso2 and hnRNPA2B1. The hexanucleotide motif 5′-AGTGTT-3′ DNA form of the nuclear localization sequence (DNLS) effectively drives cytoplasmic viral DNA nuclear translocation. These nuclear viral DNA mimics potently induce IFN-β and antiviral IFN-stimulated genes in human A549 cells, HEK293T cells, and mouse macrophages. The subcellular location difference of IFI16 isoforms determines their differential functions in recognizing viral DNA and activating type I IFN–dependent antiviral immunity. IFI16-iso1 preferentially colocalizes with cytoplasmic HSV60mer and cytoplasm-replicating vaccinia virus (VACV), whereas IFI16-iso2 mainly colocalizes with nuclear HSV60-DNLS and nucleus-replicating HSV-1. Compared with IFI16-iso2, IFI16-iso1 induces more transcription of IFN-β and IFN-stimulated genes, as well as stronger antiviral immunity upon HSV60mer transfection or VACV infection. IFI16-iso2, with the ability of nuclear-cytoplasmic shuttling, clears both invaded HSV type 1 and VACV significantly. However, IFI16-iso2 induces more type I IFN–dependent antiviral immunity than IFI16-iso1 upon HSV60-DNLS transfection or HSV type 1 infection. Our study has developed potent agonists for nuclear DNA sensors and also has demonstrated that IFI16 isoforms with cytoplasmic and nuclear locations play differential roles in innate immunity against DNA viruses.

The current teaching profession is very promising in terms of income, especially for those who have obtained a professional diploma. The government provides additional income or allowances for public and private teachers through a teacher qualification certification program. The government is trying to improve the professionalism of teachers, but in reality, there are not a few teachers who view from the wrong point of view that the professional allowance is a teacher's right and a government obligation. The purpose of this study was to determine the effect of financial literacy, financial technology, and lifestyle on financial behavior in kindergarten teachers in the Sukolilo District, Surabaya City. Determination of the sample using the slovin method with purposive sampling technique resulted in a total sample of 74 respondents. The data analysis technique used is Partial square (PLS). The results of this study indicate that financial literacy has a positive and significant effect on financial behavior, financial technology is not significant to financial behavior, and lifestyle has a positive and significant effect on financial behavior.

Association of Cancer Worry and Physical Activity Behaviors in Adults without Cancer
Authors: Lane Jamil M , Qualls Brandon W , Freeman Jason D , Rodriguez Daniel 
Published: November 2021

Background: Cancer worry has been conceptualized as a potential motivator to engage in cancer preventative behaviors like cancer screening, genetic testing, or smoking cessation. It is currently unknown if these findings extend to the domain of physical activity, as physical activity has been associated with decreased cancer risk. Objective: To examine if the association between cancer worry and other health behaviors will extend to physical activity in a sample of adults not diagnosed with cancer. Methods: Data are drawn from the NCI's 2017 Health Information National Trends Survey (HINTS) Iteration 5 Cycle 1 (N = 2,706) dataset, a nationally representative survey of adults in the United States. A KruskalWallis-H test was conducted to determine whether physical activity duration (i.e., daily minutes) differed between cancer worry levels with a post hoc Dunn's multiple comparison test to compare the differences between mean ranks. Results: A Kruskal-Wallis-H test showed statistically significant differences in PA duration (i.e., daily minutes) between groups that differed in their level of cancer worry. PA in minutes on a typical day was significantly lower in those who reported not at all, moderate, and extreme worry about developing cancer compared to those who reported slightly and somewhat worried. Conclusion: Contrary to our expectations, our results suggest that higher cancer worry levels are paradoxically associated with less PA. This study's results are significant in that they add to the breadth of literature linking cancer worry to health behaviors and may be used to inform future health promotion interventions.
Predictors of Health Insurance Literacy Among University Employees

Published: November 2021

Background: Health insurance literacy (HIL) is “the degree to which individuals have the knowledge, ability, and confidence to find and evaluate information about plans, select the best plan for their own or their families’ financial and health circumstances and use the plan once enrolled”. Many Americans have low health insurance literacy, but this concept has not been studied to the same extent as general health literacy. Objective: The purpose of this study was to explore predictors of health insurance literacy among employees of a large public institution of higher education in the South-Atlantic. Design: This single-setting cross-sectional study employed an online, anonymous survey administered to approximately 3,000 employees at a large university in the USA after open enrollment in state health insurance. The survey measured demographics and included a validated measure of health insurance literacy. Results: Using several multivariate regression models, results (N=480) indicated high overall HIL. Subscale means were highest for likelihood of using insurance plans proactively and confidence comparing insurance plans but were lower for confidence choosing and using insurance plans, indicating lack of understanding that may lead to poor insurance coverage choice and use. Employment category, income, race, and age also predicted HIL. Discussion: Based on the results, there is an opportunity for employers to provide information about health insurance policies. Health promotion programs should also seek to increase HIL through educational programs and policies to ensure both adequate coverage and ability to use health insurance in such a way that it promotes and protects one’s health.

Published: November 2021

Abstract. Climate teleconnections are essential for the verification of valuable precipitation forecasts generated by global climate models (GCMs). This paper develops a novel approach to attributing correlation skill of dynamical GCM forecasts to statistical El Niño–Southern Oscillation (ENSO) teleconnection by using the coefficient of determination (R2). Specifically, observed precipitation is respectively regressed against GCM forecasts, Niño3.4 and both of them, and then the intersection operation is implemented to quantify the overlapping R2 for GCM forecasts and Niño3.4. The significance of overlapping R2 and the sign of ENSO teleconnection facilitate three cases of attribution, i.e., significantly positive anomaly correlation attributable to positive ENSO teleconnection, attributable to negative ENSO teleconnection and not attributable to ENSO teleconnection. A case study is devised for the Climate Forecast System version 2 (CFSv2) seasonal forecasts of global precipitation. For grid cells around the world, the ratio of significantly positive anomaly correlation attributable to positive (negative) ENSO teleconnection is respectively 10.8 % (11.7 %) in December–January–February (DJF), 7.1 % (7.3 %) in March–April–May (MAM), 6.3 % (7.4 %) in June–July–August (JJA) and 7.0 % (14.3 %) in September–October–November (SON). The results not only confirm the prominent contributions of ENSO teleconnection to GCM forecasts, but also present spatial plots of regions where significantly positive anomaly correlation is subject to positive ENSO teleconnection, negative ENSO teleconnection and teleconnections other than ENSO. Overall, the proposed attribution approach can serve as an effective tool to investigate the sources of predictability for GCM seasonal forecasts of global precipitation.

Neste artigo, abordaremos a sócio-hidrodiversidade de povos indígenas e tradicionais da bacia Tocantins-Araguaia com o duplo objetivo de reconhecer seus saberes sobre as águas e contrapor estas percepções ao desenvolvimentismo do modelo agroexportador e mega-hidráulico dominante. Partindo de uma perspectiva pós-colonial, realizamos a escuta a partir de atores situados na região da Chapada dos Veadeiros, no Nordeste goiano, tendo entrevistas semiestruturadas, observação direta e participante como estratégias metodológicas. Exploramos os saberes de sujeitos provenientes dos quilombos do Moinho (Alto Paraíso de Goiás), Capela (Cavalcante) e do município de Colinas do Sul, bem como as cosmovisões dos avá-canoeiros. Como resultados, sublinhamos a importância do diálogo interepistêmico e intercultural para a ressignificação das águas do Cerrado brasileiro em favor de seu uso mais sustentável, o que pode trazer novas respostas aos dilemas civilizatórios que nos expõem a variadas crises.
