Abstract
Based on a large group/cluster catalog recently constructed from the DESI Legacy Imaging Surveys DR9 using an extended halo-based group finder, we measure and model the group–galaxy weak-lensing signals for groups/clusters in a few redshift bins within redshift range 0.1 ≤ z < 0.6. Here, the background shear signals are obtained based on the DECaLS survey shape catalog, derived with the Fourier_Quad method. We divide the lens samples into five equispaced redshift bins and seven mass bins, which allow us to probe the redshift and mass dependence of the lensing signals, and hence the resulting halo properties. In addition to these sample selections, we also check the signals around different group centers, e.g., the brightest central galaxy, the luminosity-weighted center, and the number-weighted center. We use a lensing model that includes off-centering to describe the lensing signals that we measure for all mass and redshift bins. The results demonstrate that our model predictions for the halo masses, biases, and concentrations are stable and self-consistent among different samples for different group centers. Taking advantage of the very large and complete sample of groups/clusters, as well as the reliable estimations of their halo masses, we provide measurements of the cumulative halo mass functions up to redshift z = 0.6, with a mass precision at 0.03 ∼ 0.09 dex.
Disconnecting the Dots: Re-examining the Nature of Stellar “Strings” in the Milky Way
Authors: Zucker Catherine , Peek J. E. G. , Loebman Sarah 
Published: September 2022

Abstract
Recent analyses of Gaia data have resulted in the identification of new stellar structures, including a new class of extended stellar filaments called stellar “strings,” first proposed by Kounkel & Covey. We explore the spatial, kinematic, and chemical composition of strings to demonstrate that these newfound structures are largely inconsistent with being physical objects whose members share a common origin. Examining the 3D spatial distribution of string members, we find that the spatial dispersion around the claimed string spine does not improve in the latest Gaia DR3 data release—despite tangible gains in the signal-to-noise ratio of the parallax measurements—counter to expectations of a bona fide structure. Using the radial velocity dispersion of the strings (averaging

) to estimate their virial masses, we find that all strings are gravitationally unbound. Given the finding that the strings are dispersing, the reported stellar ages of the strings are typically 120× larger than their measured dispersal times. Finally, we validate prior work that stellar strings are more chemically homogeneous than their local field stars but show it is possible to obtain the same signatures of chemical homogeneity by drawing random samples of stars from spatially, temporally, and kinematically unrelated open clusters. Our results show that while some strings may be composed of real substructures, there is no consistent evidence for larger string-like connections over the sample. These results underscore the need for caution in over-interpreting the significance of these strings and their role in understanding the star formation history of the Milky Way.

Introduction: Mass testing is essential in the surveillance strategy for fighting the COVID-19 pandemic. It allows early detection of suspected cases and subsequently early isolation to mitigate spread. However, the high cost and limited consumables and reagents hinder the mass testing strategy in developing countries such as Indonesia. The specimen pooling strategy is an option to perform mass screening with limited resources. This study aims to determine the positivity rate cut-off and to evaluate the efficiency of pooling strategy for the laboratory diagnosis of COVID-19.
Methodology: Between August 4th, 2020, and November 11th, 2020, a four-sample pooling strategy testing to detect SARS-CoV-2 was carried out at the Microbiology Diagnostic Laboratory of Diponegoro National Hospital, Semarang, Indonesia. Pools with positive results were subjected to individual specimen retesting. Spearman’s correlation and linear regression analysis were used to determine the best positivity rate cut-off to apply pooling strategy.
Results: A total of 15,216 individual specimens were pooled into 3,804 four-sample pools. Among these pools, 1,007 (26.47%) were positive. Five hundred and ten (50.64%) were 1/4 positive. A maximum positivity rate of 22% is needed to save at least 50% extraction and qRT-PCR reactions in a four-sample pooling strategy. CT values between individual specimens and pools showed a good interval agreement.
Conclusions: Pooling strategy could reduce personnel workload and reagent cost, and increase laboratory capacity by up to 50% when the positivity rate is less than 22%.

Authors: Zhang Xuehan , Fan Hongwei , Jiao Yang , Huang Xiaoming 
Published: September 2022

Introduction: Q fever is a worldwide zoonosis caused by Coxiella burnetii. Atypical presentations of Q fever can cause diagnostic difficulty or be misdiagnosed. Here we compared the clinical and diagnostic features of Q fever endocarditis and endocarditis caused by other bacteria to identify features of Q fever endocarditis that might facilitate early diagnosis.
Methodology: This was a retrospective case-control study of eight cases of Q fever endocarditis diagnosed between 2000 and 2018 at Peking Union Medical College Hospital in China and 24 age- and gender-matched patients diagnosed with bacterial endocarditis over the same period. Clinical and laboratory data were collected and compared between groups.
Results: The median time interval between symptoms and diagnosis was significantly longer in the case group than the control group (8.0 months (IQR 7.0-16.0) vs. 4.0 months (IQR 1.0-7.0); p = 0.002). Patients in case group had significantly lower white blood cell counts (5.8 ± 2.4 × 109/L vs. 10.0 ± 3.4 × 109/L; p = 0.003), percentage of neutrophil (62.4 ± 14.7% vs. 79.1 ± 9.2%; p = 0.014), high-sensitivity C-creative protein levels (21.1 mg/L (IQR 18.5-32.8) vs. 45.3 mg/L (IQR 32.9-54.3); p = 0.038), and platelet counts (133 ± 73 vs. 229 ± 65; p = 0.001) but higher levels of rheumatoid factor (104.3 U/L (IQR 99.0-132.8) vs. 10.2 U/L (IQR 6.9-32.5); p = 0.011) than controls. Elevated creatinine (50.0% vs. 12.5%; p = 0.047) and liver enzymes (50.0% vs. 0%; p = 0.002) were more common in cases than controls. Q fever endocarditis was less frequently diagnosed than controls before cardiac surgery (62.5% vs. 100%; p = 0.011), with negative blood cultures in all cases.
Conclusions: The diagnosis of Q fever endocarditis can easily be delayed compared to other causes of infectious endocarditis. Patients with chronic fever and new valve dysfunction require careful assessment, especially when presenting with negative blood cultures and high rheumatoid factor levels. Clinical and laboratory evaluation of these patients should include routine serological testing for C. burnetii.

Introduction: Tuberculosis (TB) continues to be a significant public health problem. The role of small non-coding RNAs, such as microRNAs (miRNAs), was investigated extensively in Mycobacterium tuberculosis (MTB) infection as well as in a variety of other pathophysiological processes in recent years. It was found that miRNAs act as regulators of both early reaction to MTB infection and in process of adaptation of the host immune cells during latent course of the disease. Molecule miRNA-146a is expressed exclusively in immune cells and it has the most prominent role in modulation of innate immunity.
Methodology: We investigated the level of expression of miRNA-146a using an RT-qPCR technique in peripheral blood mononuclear cells of 44 patients with active pulmonary TB and 17 healthy individuals. We also analyzed the significance of miRNA-146a rs2910164 SNV for expression profile of miRNA-146a, in order to investigate potential usage of miRNA-146a as a biomarker for TB.
Results: There was statistically significant decrease of expression of miRNA-146a in TB group compared to control group. When gender cohorts were analyzed, the expression levels in TB male and TB female subgroup were significantly lower than the expression levels in the same gender control subgroups.
Conclusions: Our results indicate that miRNA-146a plays a significant role in the pathogenesis of TB, suggesting that miRNA-146a could be used as a biomarker for active pulmonary TB.

Published: September 2022

BACKGROUND: The COVID-19 pandemic was first announced in Indonesia on March 2, 2020, which affected health services including vaccination for children.

AIM: The purpose of this study was to determine whether there were differences in children vaccination in Indonesia before the COVID-19 pandemic (2019) and during the COVID-19 pandemic (2020).

METHODS: This study applied cross-sectional design with the Paired Sample t-test test. The research data were obtained from the East Java Provincial Health Office in January-December 2019 and January-December 2020 which consisted of 968 first-level health-care facilities spread over 38 districts in East Java, Indonesia.

RESULTS: The results of this study were 3.85–10.57, with t values of 4.348 and df 37 and p = 0.000 so that there was a significant difference in vaccination of Indonesian children before the COVID-19 pandemic and during the COVID-19 pandemic. The Mean ± SD value before the pandemic in 2019 was 18.57 ± 12.87 and during the pandemic in 2020 was 11.36 ± 9.47.

CONCLUSIONS: Vaccination of children in Indonesia decreased between before and during the COVID-19 pandemic because of a policy to stay at home and avoid crowds. Parents and children were reluctant to come to the posyandu (Integrated Health Post). The involvement of posyandu cadres is needed to be able to increase child vaccination in Indonesia.

Authors: Kal Elmar , Ellmers Toby , Hogg Jennifer , Slutsky-Ganesh Alexis B. , Bonnette Scott , Thomas Staci , Riehm Christopher D. , Myer Gregory D. , Diekfuss Jed A. 
Published: September 2022

Context
Visual biofeedback has been shown to facilitate injury-resistant movement acquisition in adolescent athletes. Visual biofeedback is typically thought to foster implicit learning by stimulating athletes to focus attention externally (on movement outcome). However, biofeedback may also induce explicit learning if the athlete uses the visual information to consciously guide movement execution (via an internal focus).

Objective
To determine the degree to which athletes reported statements indicating implicit or explicit motor learning after engaging in a visual biofeedback intervention.

Design
Prospective cohort study.

Setting
Three-dimensional motion-analysis laboratory.

Patients or Other Participants
Twenty-five adolescent female soccer athletes (age = 15.0 ± 1.5 years, height = 165.7 ± 5.9 cm, mass = 59.4 ± 10.6 kg).

Interventions
Standard 6-week neuromuscular training intervention (three 90-minute sessions/wk), with added visual biofeedback sessions (2 sessions/wk). For the biofeedback training, participants performed squatting and jumping movements while interacting with a visual rectangular stimulus that mapped key parameters associated with injury risk. After the last biofeedback session in each week, participants answered open-ended questions to probe learning strategies.

Main Outcome Measure(s)
Responses to the open-ended questions were categorized as externally focused (ie, on movement outcome, suggestive of implicit learning), internally focused (ie, on movement itself, suggestive of explicit learning), mixed focus, or other.

Results
A total of 171 open-ended responses were collected. Most of the responses that could be categorized (39.2%) were externally focused (41.8%), followed by mixed (38.8%) and internally focused (19.4%). The frequency of externally focused statements increased from week 1 (18%) to week 6 (50%).

Conclusions
Although most statements were externally focused (suggesting implicit learning), the relatively large proportion of internal- and mixed-focus statements suggested that many athletes also engaged in explicit motor learning, especially in early practice sessions. Therefore, biofeedback may affect motor learning through a mixture of implicit and explicit learning.

Authors: Sweeney Emily A. , Little Casey C. , Wilson Julie C. , Potter Morgan N. , Seehusen Corrine N. , Howell David R. 
Published: September 2022

Context
Sever's disease (calcaneal apophysitis) is a common condition in youth athletes, including those who participate in barefoot sports. Health care professionals often recommend that young athletes with Sever's disease wear heel cups in their shoes while active, but barefoot athletes are unable to use heel cups.

Objective
To compare the efficacy of 2 braces used by barefoot athletes with Sever's disease.

Design
Randomized controlled clinical trial.

Setting
Pediatric sports medicine clinic.

Patients or Other Participants
A total of 43 barefoot athletes aged 7 to 14 years were enrolled, and 32 completed the study (age = 10.3 ± 1.6 years; 29 girls, 3 boys).

Intervention(s)
Participants were randomized to the Tuli's Cheetah heel cup (n = 16) or Tuli's The X Brace (n = 16) group for use during barefoot sports over the 3-month study period.

Main Outcome Measure(s)
Participants completed self-reported assessments after diagnosis (baseline) and 1, 2, and 3 months later. The primary outcome was the Oxford Ankle Foot Questionnaire for Children (OxAFQ-C) physical score (3 months postenrollment). The secondary outcomes were OxAFQ-C school or play and emotional scores and the visual analog scale pain score.

Results
The percentage of time wearing the brace during barefoot sports was not different between the Cheetah heel cup and The X Brace groups (82% versus 64% of the time in sports; P = .08). At 3 months, we observed no differences for the OxAFQ-C physical (0.79 versus 0.71; P = .80; Hedges g = 0.06), school or play (0.94 versus 1.00; P = .58; Hedges g = 0.26), or emotional (1.00 versus 1.00; P = .85; Hedges g = 0.21) score. Visual analog scale pain scores during activities of daily living and sports were lower (better) at the 2- and 3-month time points than at baseline (P &lt; .001).

Conclusions
Both groups demonstrated improvements in ankle and foot function across time, but no between-groups differences were seen at 3 months. Given these results, barefoot athletes with Sever's disease may consider using either brace with barefoot activity to help improve pain and functional status.
Messenger RNA expression of toll-like receptors (TLR2, TLR4, and TLR9) in HIV-1 infected patients with and without tuberculosis co-infection
Authors: Kaushik Gaurav , Vashishtha Richa 
Published: September 2022

Background:
Gene expression levels of TLRs (TLR2, TLR4 and TLR9) are directly involved in the virus recognition and initiation of innate immune responses, therefore, the effect of HIV infection on TLRs gene expression was investigated in functional context through mRNA levels estimations of selected TLRs.

Methods:
In the present study mRNA gene expression of TLR2, TLR4 and TLR9 has been investigated in HIV+ and HIV+TB patients and compared with healthy subjects.

Result:
The increase expression of TLR2, TLR4 and TLR9 (mRNA level) relative to the internal gene GAPDH was observed in HIV+ and HIV+TB patients as compared to healthy subjects. Similarly, increase in TLRs mRNA expression was observed in HIV+TB patients as compared to HIV+ patients.

Conclusion:
A modest increase in expression of TLRs in HIV+ patients with and without TB co-infection suggest a potential role for these TLRs in HIV-1 immunopathogenesis.

RELIABLE ENTERPRISE VALUATION METHODS: A CASE STUDY ON ROMANIA’S INVESTMENT FUNDS
Authors: Bulău Vlad 
Published: September 2022

<p>Professionals in enterprise valuation can use multiple methods and approaches for the valuation mission. To support them, the standards in the matter use the market approach, income approach, and cost approach. The market approach or comparison approach refers to determining the value of an entity or the common equity of an entity using direct comparison with other enterprises or similar shares traded on the free market (the price of which is public). The sources of information concerning such data are mainly the stock exchanges and the M&amp;A (mergers and acquisitions) operations and preceding transactions with similar companies. The most common multiples in the market-based approach are PER (Price Earnings Ratio), PEG (Price Earnings to Growth), and EV/EBITDA. Within this study, we highlighted the extent to which these multiples reflect or not the market value of the companies analysed, as defined by the stock exchange mechanism. Furthermore, to achieve this goal we set out to establish the validity of three hypotheses regarding the ability of multiple-based methods to highlight a stock’s market price. Using a quantitative approach and historical data we demonstrated that market-based multiples are a safe way to obtain an enterprise’s fair value, pointing out that results vary slightly depending on the variables used.</p><p> </p><p><strong>JEL</strong>: M40, M41, M49</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0333/a.php" alt="Hit counter" /></p>
