A VENUS-MASS PLANET ORBITING A BROWN DWARF: A MISSING LINK BETWEEN PLANETS AND MOONS

The co-planarity of solar system planets led Kant to suggest that they formed from an accretion disk, and the discovery of hundreds of such disks around young stars as well as hundreds of co-planar planetary systems by the Kepler satellite demonstrate that this formation mechanism is extremely widespread. Many moons in the solar system, such as the Galilean moons of Jupiter, also formed out of the accretion disks that coalesced into the giant planets. Here we report the discovery of an intermediate system, OGLE-2013-BLG-0723LB/Bb, composed of a Venus-mass planet orbiting a brown dwarf, which may be viewed either as a scaled-down version of a planet plus a star or as a scaled-up version of a moon plus a planet orbiting a star. The latter analogy can be further extended since they orbit in the potential of a larger, stellar body. For ice-rock companions formed in the outer parts of accretion disks, like Uranus and Callisto, the scaled masses and separations of the three types of systems are similar, leading us to suggest that the formation processes of companions within accretion disks around stars, brown dwarfs, and planets are similar.
The course of multidrug-resistant pulmonary tuberculosis in HIV-infected people with COVID-19

Aim. To analyze the course of multidrug-resistant tuberculosis (MDR-TB) in HIV-infected people, depending on the time to COVID-19 diagnosis, using the example of clinical cases from our own observation. Materials and methods. The article presents 3 clinical cases of our own observation of MDR-TB in HIV-infected persons depending on the time to COVID-19 diagnosis in patients, who were treated in the Pulmonary Tuberculosis Department No. 2, clinical base of the Department of Tuberculosis and Pulmonology ZSMU – Municipal non-profit enterprise “Zaporizhzhia Regional Phthisiopulmonology Clinical Medical and Diagnostic Center” of Zaporizhzhia Regional Council. Results. In clinical case 1, in an HIV-infected patient, MDR TB was detected after COVID-19. This clinical case has shown that after mild and treated COVID-19, even on the background of severe immunosuppression, but with AMBT and ART timely prescribed, MDR-TB in the patient had a favorable course with positive dynamics. In clinical case 2, in an HIV-infected patient, MDR-TB was detected concomitantly with COVID-19. The clinical case indicated that the patient received all 3 therapies for MDR-TB, HIV and COVID-19 in full and on time. In contrast to clinical case 1, the patient was diagnosed with a more severe process that required a longer period of treatment, although it was effective. In clinical case 3, an HIV-infected patient with COVID-19 was diagnosed after 5 months of MDR-TB treatment. Against this background, there was culture positivity. But after prescription of appropriate COVID-19 treatment against the background of AMBT and ART, positive dynamics and culture negativity were determined. All 3 patients completed antimycobacterial therapy of MDR-TB with results – recovery. Conclusions. Regardless of the HIV infection duration with underlying severe immunosuppression (<200 CD4 lymphocyte cells) and the time to COVID-19 diagnosis (before, during or after the diagnosis of MDR-TB) on the background of timely therapy of MDR-TB, HIV and COVID-19, positive results can be achieved while saving the lives of patients.
Effects of Cadmium Stress on Root and Root Border Cells of Some Vegetable Species with Different Types of Root Meristem

Cadmium is one of the most toxic heavy metals and can be easily absorbed by plants, affecting root growth. Root border cells (RBCs), that are located in the periphery of the root cap and originate from the root cap meristem, represent a convenient tool to study the toxic effects of Cd on root performance. In this work, vegetables with contrasting types of root apical meristem (RAM) organizations were used. The open RAM organizations included pea and cucumber, and the closed RAM organizations included tomato, chili, and eggplant. The number of RBCs were significantly higher in the species possessing open RAM organization: pea (11,330 cells per root) > cucumber (8200) > tomato (2480) > eggplant (1830) > chili (1320). The same trend was observed for cell viability: pea (61%) > cucumber (59%) > tomato (49%) > eggplant (44%) > chili (42%). Pea and cucumber had higher relative radicle elongation rates and a lower increase in stress-induced accumulation of malondialdehyde (MDA), making them more resistant to Cd stress than the vegetables with close RAM organization. Under Cd treatment, the number and viability of RBCs in vegetables with both types of RAM organization were significantly decreased. However, the decreasing ratio of the number and viability of RBCs in pea and cucumber was higher than in tomato, chili, and eggplant. Taken together, the plants with the open-type RAM are more tolerant to Cd, and it can be speculated that the cadmium tolerance of the vegetables may be correlated with the number and viability of RBCs in response to cadmium stress.
Progress in quantum electrodynamics theory of highly charged ions

Recent progress in quantum electrodynamics (QED) calculations of highly charged ions is reviewed. The theoretical predictions for the binding energies, the hyperfine splittings, and the g factors are presented and compared with available experimental data. Special attention is paid to tests of bound‐state QED at strong field regime. Future prospects for tests of QED at the strongest electric and magnetic fields as well as for determination of the fine structure constant and the nuclear magnetic moments with heavy ions are discussed.
Employee-friendly practices and corporate financial performance: Evidence from a frontier market

Abstract This study investigates the association between employee-friendly schemes and firm financial performance using a frontier market, Vietnam, as a research context. We employ Anphabe’s “Top 100 Vietnam Best Places to Work” lists to identify companies with ideal employee-friendly practices. Using a data sample of more than 3,800 firm-year observations, we document a strong and positive relationship between employee welfare and firm performance measured by Tobin’s q. Our result is robust to a battery of sensitivity tests, including an alternative indicator of financial performance, alternative selection criteria, and different econometric techniques.
“It took me back 25 years in one bound”: self-generated flavor-based cues for self-defining memories in later life

“. those short, plump little cakes called petites madeleines [. ] I raised to my lips a spoonful of the tea in which I had soaked a morsel of the cake.

Caffeic Acid Induces Intrinsic Apoptotic Pathway in MG-63 Osteosarcoma Cells Through Bid Truncation and Cytochrome c Release

BACKGROUND: Caffeic acid has been reported to induce apoptosis in MG-63 osteosarcoma cells via caspases activation. However, apoptotic pathway that is involved in the caffeic acid-induced apoptosis is still unclear. Present study aimed to investigate the role of cytochrome c (Cyt c) release and BH3-interacting death (Bid) activation in caffeic acid-induced apoptosis in MG-63 osteosarcoma cells.METHODS: MG-63 cells were cultured, pretreated with/without Z-VAD FMK and treated with/without 10 μg/mL caffeic acid. Treated MG-63 cells were then lysed, homogenized, and processed further to prepare cell lysate and mitochondrial fraction. Immunoblotting method was used to measure the amount of Bid and truncated Bid (t-Bid) as well as mitochondrial and cytosolic Cyt c.RESULTS: The amount of Bid and mitochondrial Cyt c in MG-63 cells decreased in a time-dependent manner, while the amount of t-Bid and cytosolic Cyt c increased in a time-dependent manner. By pretreatment of 100 μM Z-VAD-FMK for 2 h, the amount of Bid and mitochondrial Cyt c was significantly higher, while the amount of t-Bid and cytosolic Cyt c was significantly lower after caffeic acid treatment for 6 and 12 h compared to MG-63 cells that were not pretreated.CONCLUSION: Caffeic acid could induce Cyt c release through the activation of Bid in MG-63 osteosarcoma cells.KEYWORDS: caffeic acid, osteosarcoma, MG-63 cells, Bid, t-Bid, cytochrome c, Z-VAD-FMK
Determinants of quality of life in patients with hemorrhagic stroke, Saudi Arabia: A cross-sectional study

Background: Previous studies demonstrated that stroke had an inverse impact on patients' physical, mental, and social quality of life. Aim: To determine factors contributing to the health-related quality of life (HRQOL) of Saudi hemorrhagic stroke survivors. Methods: A cross-sectional study was done at King Abdulaziz University Hospital (KAUH), Jeddah, KSA, on adult stroke patients. Data about the patients' socio-demographic characters and clinical data were obtained. The Stroke-Specific QOL (SSQOL) scale was used to measure the HRQOL. Results: The mean Stroke-Specific QOL (SSQOL) domains sore was 163.8 ± 46.29. Male patients and those who had bilateral lesions had a significantly higher mean SSQOL score. A non-significant positive correlation was found between the SSQOL score and the patients' age and post-stroke duration. And a non-significant relationship was found between mean SSQOL score and patients' nationality, educational level, smoking, marital and financial status, income, social support, insurance or other clinical data, hemorrhagic type, surgical treatment and follow up, comorbidities, or the year and duration of diagnosis. Conclusion: There is a need to use stroke rehabilitation programs to improve physical and functional independence and take into account the influence of the side of lesion on HRQOL.
The Radio Properties of NGC 5253 and Its Unusual H II Regions

We present VLA images of the radio continuum emission of the starburst in NGC 5253 at wavelengths of 6, 3.6, and 2 cm, with resolutions of 1″–2″, and at 20 cm with resolution of ∼9″. A spectral index map constructed from the 6 and 2 cm images indicates that thermal free-free emission from ionized gas, most of it from a single source, dominates the radio emission. The unusually high fraction of free-free emission suggests that the starburst is very young. Regions of diffuse nonthermal synchrotron emission and probable supernova remnants surround the central radio source. We detect several regions of rising spectral index in NGC 5253, suggesting that the free-free emission is optically thick at 2 cm. These nebulae are situated to the north of the central cluster/main radio source. The turnover frequencies require an emission measure (EM) ∼ 108–109 cm-6 pc, and ⟨n⟩1/2 ∼ 104–105 cm-3. From the observed intensities, we infer diameters of a few tenths of a parsec for these regions, which is an order of magnitude larger than the diameters of H II regions of comparable density in the Galaxy. Lyman continuum rates of over NLyc ∼ 1051 s-1 are required to ionize these high densities and volumes. Unlike Galactic compact H II regions, which contain no more than a few O stars, the optically thick H II regions in NGC 5253 are excited by an estimated 200–1000 O stars each. This is consistent with the idea that very large clusters are the mode of star formation in the central region of NGC 5253. The optically thick H II regions, located to the north of the dominant optical and radio sources, may well trace the very youngest parts of the starburst.
Student engagement with computer-mediated teacher written corrective feedback: A case study

Much of the research on the effectiveness of written corrective feedback (WCF) scope and strategies has been (quasi-)experimental, generating results peripherally related to authentic classroom contexts. Underpinned by a multidimensional conceptual framework of student engagement with WCF, this classroom-based study has explored the scope and strategies used by the teacher regarding WCF. It also investigated how two ESL university students behaviorally, cognitively, and affectively engaged with the scope and strategies of computer-medi-ated teacher WCF to improve the accuracy of the second draft of the introduction and methodology sections of their research proposal. Data from multiple sources, including students’ written texts, screencasts that captured students’ revision process, stimulated recall, and semi-structured interviews were analyzed. The findings revealed that the scope of computer-mediated teacher WCF was comprehensive, and the most frequently employed feedback strategy was direct WCF, often accompanied by metalinguistic explanation. Behaviorally, the students improved their drafts’ accuracy based on such feedback; however, their cognitive engagement was mediocre. Although affectively the students often experienced positive reactions toward feedback strategies, they felt overwhelmed by a large number of comments. and sub-constructs are: (a) immediate emotional reactions upon receiving feedback and (b) attitudinal response to feedback.
Bray‐Curtis (AFD) differentiation in molecular ecology: Forecasting, an adjustment ( A A), and comparative performance in selection detection

Abstract Geographic genetic differentiation measures are used for purposes such as assessing genetic diversity and connectivity, and searching for signals of selection. Confirmation by unrelated measures can minimize false positives. A popular differentiation measure, Bray‐Curtis, has been used increasingly in molecular ecology, renamed AFD (hereafter called BCAFD). Critically, BCAFD is expected to be partially independent of the commonly used Hill “Q‐profile” measures. BCAFD needs scrutiny for potential biases, by examining limits on its value, and comparing simulations against expectations. BCAFD has two dependencies on within‐population (alpha) variation, undesirable for a between‐population (beta) measure. The first dependency is derived from similarity to GST and FST. The second dependency is that BCAFD cannot be larger than the highest allele proportion in either location (alpha variation), which can be overcome by data‐filtering or by a modified statistic A A or “Adjusted AFD”. The first dependency does not forestall applications such as assessing connectivity or selection, if we know the measure's null behavior under selective neutrality with specified conditions—which is shown in this article for A A, for equilibrium, and nonequilibrium, for the commonly used data type of single‐nucleotide‐polymorphisms (SNPs) in two locations. Thus, A A can be used in tandem with mathematically contrasting differentiation measures, with the aim of reducing false inferences. For detecting adaptive loci, the relative performance of A A and other measures was evaluated, showing that it is best to use two mathematically different measures simultaneously, and that A A is in one of the best such pairwise criteria. For any application, using A A, rather than BCAFD, avoids the counterintuitive limitation by maximum allele proportion within localities.
Theoretical and experimental results for the dynamic response of pressure measuring systems

For a series-connection of N thin tubes and N volumes a general recursion formula has been derived that relates the sinusoidal pressure disturbance in volume; to the pressure disturbances in the preceding volume j and the next volume j - 1. From this recursion formula the expressions for the complex ratio of the pressure fluctuation of each volume ; to the sinusoidal input pressure Po can be derived by successively putting j = N, N - 1,. 2, 1. For a single pressure measuring system (N = 1) and a double pressure measuring system (N = 2) these dynamic response formulae are given explicitely. Theoretical results for single pressure measuring systems are presented that demonstrate the influence of the different parameters. As an illustrative example of the double pressure measuring system some calculations have been performed for a system with a discontinuity in tube radius. Comparison of theoretical and experimental results shows that the response characteristics of the pressure measuring systems considered can be predicted theoretically to a high degree of accuracy.
Labour market collectivism: New solidarities of highly skilled freelance workers in medicine, IT and the film industry

Highly skilled freelance workers are mainly depicted as a challenge to trade unionism because of their mobility, market power and specific interests in organisational support. The authors explore the manifestations of collectivism of highly skilled freelance workers on the basis of semi-structured interviews with 14 highly skilled freelancers and 35 representatives of intermediaries such as trade unions, professional associations, staffing agencies and cooperatives in medicine, IT and film in Germany. The results reveal new forms and dynamics of labour market collectivism arising from concurrent conflicts and negotiations of job access and working conditions.
Financial factors influencing environmental, social and governance ratings of public listed companies in Bursa Malaysia

Abstract Environmental, Social and Governance (ESG) ratings are widely recognised methods to assess the sustainability practices of corporations. However, the scores of these ratings are not satisfactory in emerging market economies. This study examines the financial factors that influence ESG ratings regarding public listed companies on the FTSE4 Good Bursa Malaysia Index (F4GBM Index). This paper uses static and dynamic Generalized Method of Moments (GMM) techniques to analyse the data of 31 public listed companies on the F4GBM Index and reported full ESG ratings data for the period 2007–2016. To utilise the maximum number of observations by avoiding the missing data and outlier due to COVID-19, this study applied the sample data up to 2016. Using the two-step system dynamic GMM estimator, such results indicate that highly profitable Malaysian companies enjoy a higher score for ESG overall ratings as well as all three individual ratings. Poorer credit management diminishes the environmental ratings, yet increases overall scores such as the social and governance scores. Companies with higher leverage have a weaker social, governance and overall score, but a higher environmental rating. Finally, companies eliciting a higher sustainable growth rate have weak governance and overall scores. This study provides empirical evidence that will be useful to capital market investors, management teams of these companies and policymakers in their efforts to promote responsible investment in Malaysian public listed companies in line with UN-PRI policy.
Trend analysis in rainfall time series in some Brazilian semiarid cities

Nowadays, the climate changes are a frequent issue of the scientific community, and although it occurs on a global scale, its impacts often vary from region to region. The objective of this research was to identify the climatic change trends from rainfall in some Brazilian semiarid cities of the Pernambuco state. The Mann-Kendall and Sen-slope trend tests were applied to detect possible trends in the rainfall time series. In addition, the Pettitt test was also applied to identify abrupt changes in precipitation records represented by break points in the time series. The results showed trends of climatic changes in rainfall in fifteen cities, being observed in some localities the decrease of the tendencies in the rainy season, representing a serious problem that compromises the water supply, suppresses agricultural activities, thus making life difficult for the population, because it's in this short rainy season that the water reservoirs of the region are replenished.
Racial invariance in rural and urban contexts: comparing the structural sources of Black, White, and Latinx homicide in rural and urban counties, 2000 and 2010

Abstract Structural disadvantage has long been empirically linked to violent crime across different race/ethnic groups. More recently conceptualized as “racial invariance,” observed racial differences in crime rates are hypothesized to be the result of disparities in community-level structural conditions. However, most investigations into this hypothesis have focused on urban settings, with limited attention to rural contexts. The current study seeks to fill this gap by comparing county-level structural predictors of homicide victimization for Black, White, and Latinx populations in both urban and rural communities. Consistent with the racial invariance hypothesis, findings reveal that disadvantage strongly predicts homicide across race/ethnicity in both rural and urban counties. Closer inspection of results, however, exposes noteworthy differences in the effects in rural and urban settings.
Experiments using high-Tc/low-Tc Josephson contacts

Remarkably rich physics is involved in the behavior of hybrid Josephson junctions, connecting high-Tc and low-Tc superconductors. This relates in particular to the different order parameter symmetries underlying the formation of the superconducting states in these materials. Experiments on high-Tc/low-Tc contacts have also played a crucial role in settling the decade-long d-wave versus s-wave debate in cuprate superconductors. Recently, such hybrid junctions have enabled more detailed pairing symmetry tests. Furthermore, with these junctions, complex arrays of pi-rings have been realized, enabling studies on spontaneously generated fractional flux quanta and their mutual interactions. Steps toward novel superconducting electronic devices are taken, utilizing the phase-shifts inherent to the d-wave superconducting order parameter. This paper is intended to reflect the current status of experiments using high-Tc and low-Tc Josephson contacts.
