Technical Indices Evaluation of Radial Distribution Network with Optimally Allocated DGs and Capacitors
Authors: Manjhi Rampreet , Lal Deepak Kumar , Biswal Sandeep , Abdelaziz Almoataz Y. 
Published: September 2024

Electric power distribution system planning is a key area of concentration for developing more efficient, trustworthy, and environmentally friendly energy sources in the future. While distributed generations (DGs) are excellent at reducing system actual power losses, shunt capacitors can supplement their effectiveness when utilized in tandem. It is feasible to achieve even higher reductions in power losses and enhanced system efficiency by combining DGs with shunt capacitors. The Loss Sensitivity Factor (LSF) measures how sensitive real power loss in a network is to changes in power injection (active or reactive power) at a single bus. The methodology analyses LSFs to assess the ideal sites for placing DGs and capacitors in radial distribution networks (RDNs). The Golden Jackal Optimization (GJO) strategy is adopted to discover the ideal sizing and allocation of DGs and capacitors. The strategy is tested using two RDNs, one with 33 buses and the other with 69 buses. In addition, five major technical indices are explored and examined, used as an evaluation criterion to distinguish between the optimal and baseline performances. These are the voltage deviation index (VDI), power loss index (PLI), fast voltage stability index (FVSI), line stability factor (LQP), and novel line stability index (NLSI). Voltage deviation, power loss, and voltage stability analysis-related indices are among the technical characteristics addressed.
Whale Optimization Algorithm Based Closed-Loop Control Z-source inverter for Wind Energy Application
Authors: Kumari Sweta , Kumar Mandal Rajib 
Published: September 2024

In this paper, an enhanced 0.5 kW Z-source inverter (ZSI) model is used in the design of a wind energy generating system (WEGS) that uses a 1.2 kW wind turbine to overcome the operating restrictions of the traditional ZSI model. To achieve a constant line-to-line voltage with varying loads at the output side of the WEGS, a closed-loop control technique is applied at the load side. A proportional-integral (PI) controller is utilised with the ZSI for closed-loop control since it is the least complicated in terms of tuning and operation. Also, ZSI systems have nonlinear behaviour, which precludes direct application of the PI controller technique to them. As a result, the novelty of this article is the optimisation of stabilised PI coefficients (Kp, Ki) with a modified ZSI model. Particle swarm optimisation (PSO), sine-cosine algorithm (SCA), and whale optimisation algorithm (WOA)-based optimisation techniques are used to handle PI tuning for closed-loop modified ZSI. In terms of the stability of the closed-loop modified ZSI with WEGS, the WOA performs better. The outcomes show that the suggested controller can control the variation in AC output voltage of ZSI with variable load exactly.

Abstract
We used the Keck Planet Imager and Characterizer to obtain high-resolution (R ∼ 35,000) K-band spectra of κ Andromedae b, a planetary-mass companion orbiting the B9V star, κ Andromedae A. We characterized its spin, radial velocity, and bulk atmospheric parameters through use of a forward-modeling framework to jointly fit planetary spectra and residual starlight speckles, obtaining likelihood-based posterior probabilities. We also detected H2O and CO in its atmosphere via cross correlation. We measured a

SOLES XII. The Aligned Orbit of TOI-2533 b, a Transiting Brown Dwarf Orbiting an F8-type Star
Authors: dos Santos Thiago Ferreira , Rice Malena , Wang Xian-Yu , Wang Songhu 
Published: September 2024

Abstract
Brown dwarfs occupy a middle ground in mass space between gaseous giant planets and ultracool dwarf stars, and the characterisation of their orbital orientations may shed light on how these neighbouring objects form. We present an analysis of the Rossiter–McLaughlin effect across the transit of TOI-2533 b, a brown dwarf on a moderately eccentric (e

b

b
/R
⋆ = 13.34 ± 0.30) orbit around an F8-type star, using data from the NEID/WIYN spectrograph in combination with archival photometry and radial velocity observations. Spin-orbit analyses of brown dwarfs are relatively rare, and TOI-2533 stands out as the fifth brown dwarf system with a measured spin–orbit constraint. We derive a sky-projected stellar obliquity of λ = −7° ± 14° for TOI-2533 b, finding that the brown dwarf is consistent with spin–orbit alignment. Our joint model also indicates that TOI-2533 b falls near the lower bound of the hydrogen-burning minimum mass range (M

Jup). Ultimately, we find that TOI-2533 b is consistent with formation from disc fragmentation in a primordially spin–orbit aligned orientation, although we cannot rule out the possibility that the system has been tidally realigned during its lifetime.
Distances to Recent Near-Earth Supernovae from Geological and Lunar 60Fe
Authors: Ertel Adrienne F. , Fields Brian D. 
Published: September 2024

Abstract
Near-Earth supernova blasts which engulf the solar system have left traces of their ejecta in the geological and lunar records. There is now a wealth of data on live radioactive 60Fe pointing to a supernova at 3 Myr ago, as well as the recent discovery of an event at 7 Myr ago. We use the available measurements to evaluate the distances to these events. For the better analyzed supernova at 3 Myr, samples include deep-sea sediments, ferromanganese crusts, and lunar regolith; we explore the consistency among and across these measurements, which depends sensitively on the uptake of iron in the samples as well as possible anisotropies in the 60Fe fallout. There is also significant uncertainty in the astronomical parameters needed for these calculations. We take the opportunity to perform a parameter study on the effects that the ejected 60Fe mass from a core-collapse supernova and the fraction of dust that survives the remnant have on the resulting distance. We find that with an ejected 60Fe mass of 3 × 10−5
M
⊙ and a dust fraction of 10%, the distance range for the supernova 3 Myr ago is D ∼ 20–140 pc, with the most likely range between 50 and 65 pc. Using the same astrophysical parameters, the distance for the supernova at 7 Myr ago is D ∼ 110 pc. We close with a brief discussion of geological and astronomical measurements that can improve these results.
Probing the Spectrum of the Magnetar 4U 0142+61 with JWST

Abstract
JWST observed the magnetar 4U 0142+61 with the Mid-Infrared Instrument (MIRI) and Near Infrared Camera (NIRCam) instruments within a 77 minute time interval on 2022 September 20–21. The low-resolution MIRI spectrum and NIRCam photometry show that the spectrum in the wavelength range 1.4–11 μm range can be satisfactorily described by an absorbed power-law (PL) model, f

V
= 3.9 ± 0.2, and normalization f
0 = 59.4 ± 0.5 μJy at λ = 8 μm. These observations do not support the passive disk model proposed in 2006 by Wang, Chakrabarty and Kaplan, based on Spitzer photometry, which was interpreted as evidence for a fallback disk from debris formed during the supernova explosion. We suggest a nonthermal origin for this emission and source variability as the most likely cause of discrepancies between the JWST data and other IR-optical observing campaigns. However, we cannot firmly exclude the presence of a large disk with a different dependence of the effective disk temperature on distance from the magnetar. Comparison with the PL fit to the hard X-ray spectrum above 10 keV, measured by the NuSTAR contemporaneously with JWST, shows that the X-ray spectrum is significantly harder. This may imply that the X-ray and IR nonthermal emission come from different sites in the magnetosphere of the magnetar.
Gaussian Process Approach for Model-independent Reconstruction of f(Q) Gravity with Direct Hubble Measurements
Authors: Gadbail Gaurav N. , Mandal Sanjay , Sahoo P. K. 
Published: September 2024

Abstract
The increase of discrepancy in the standard procedure to choose the arbitrary functional form of the Lagrangian f(Q) motivates us to solve this issue in modified theories of gravity. In this regard, we investigate the Gaussian process, which allows us to eliminate this issue in an f(Q) model-independent way. In particular, we use the 58 Hubble measurements coming from cosmic chronometers and the radial Baryon acoustic oscillations to reconstruct H(z) and its derivatives

and H″(z), which leads us to reconstruct the region of f(Q), without any assumptions. The obtained mean curve along the Lambda Cold Dark Matter (ΛCDM) constant in the reconstructed region follows a quadratic behavior. This motivates us to propose a new f(Q) parameterization, i.e., f(Q) = −2Λ + ϵ
Q
2, with the single parameter ϵ, which signifies the deviations from ΛCDM cosmology. Further, we probe the widely studied power-law and exponential f(Q) models against the reconstructed region and can improve the parameter spaces significantly compared with observational analysis. In addition, the direct Hubble measurements, along with the reconstructed f(Q) function, allow the H
0 tension to be alleviated.

Abstract
We present an atmospheric retrieval analysis on a set of young, cloudy, red L dwarfs—CWISER J124332.12+600126.2 (BD+60 1417B) and WISEP J004701.06+680352.1 (W0047)—using the Brewster retrieval framework. We also present the first elemental abundance measurements of the young K-dwarf (K0) host star, BD+60 1417, using high-resolution (R = 50,000) spectra taken with the Potsdam Echelle Polarimetric and Spectroscopic Instrument on the Large Binocular Telescope. In the complex cloudy L-dwarf regime the emergence of condensate cloud species complicates retrieval analysis when only near-infrared data are available. We find that for both L dwarfs in this work, despite testing three different thermal profile parameterizations we are unable to constrain reliable abundance measurements and thus the carbon-to-oxygen ratio. While we cannot conclude what the abundances are, we can conclude that the data strongly favor a cloud model over a cloudless model. We note that the difficulty in retrieval constraints persists regardless of the signal-to-noise ratio of the data examined (S/N ∼ 10 for CWISER BD+60 1417B and 40 for WISEP W0047). The results presented in this work provide valuable lessons about retrieving young, low-surface-gravity cloudy L dwarfs. This work provides continued evidence of missing information in models and the crucial need for JWST to guide and inform retrieval analysis in this regime.
Treatment with biologics of patients with inflammatory joint diseases
Authors: Stoilova Stefka , Taneva Daniela , Geneva-Popova Mariela 
Published: September 2024

Over the past two decades, biologics (Bs) have been widely used in the treatment of patients with inflammatory joint diseases (IJD). The treatment of IJD aims at reducing disease progression, improving patients’ physical health and well-being, and achieving long-lasting remission or, at least, minimal disease activity. The introduction of Bs in rheumatology practice has significantly improved patients’ outcomes and prognosis. Their use, however, involves undertaking significant risks and challenges for both patients and medical teams.
The purpose of this article is to provide a brief overview of the biological therapies currently approved for this group of diseases in Bulgaria and the indications for administration and monitoring of the most common side effects. The optimal administration of Bs is determined by treatment efficacy, discussion of benefits and risks, prevention of the possible development of severe adverse effects, administration regimens, and routes of administration of Bs. The analysis of major issues during treatment helps summarize the information on the use of Bs, thus increasing the possibility of managing the risks associated with their use by strengthening the engagement of healthcare experts and patients in the process of monitoring the impact of biological agents.

Authors: Budiyanto  , Prihaningtyas Rendi Aji , Setyoboedi Bagus , Arief Sjamsul 
Published: September 2024

Background: Neonatal cholestasis affects 1 in 2,500 term infants, biliary atresia being the most common and severe cause. Histopathological examination of liver biopsy remains the gold standard for diagnosis, the METAVIR index determining the degree of liver damage. Aspartate aminotransferase-to-platelet ratio index (APRI) is a simple, non-invasive method that can be used to predict liver fibrosis in chronic liver disease. Objectives: To study the correlation of APRI and the METAVIR index in subjects with infantile cholestasis.Method: Infants with cholestasis who underwent liver biopsy and were assessed by the METAVIR index from 2005 to 2023 in Dr. Soetomo Hospital were included retrospectively. APRI at the time of the liver biopsy was calculated. Statistical analysis with Pearson correlation was performed, and a Receiver Operating Characteristic (ROC) curve was used to assess the diagnostic performance of APRI for significant liver fibrosis (=F2) and cirrhosis (=F4).Results: Twenty-seven patients were included; 12 (44%) were females, with a mean age of 4.7±3.9 months. METAVIR F4 was seen in 8 (30%), F3 in 3 (11%), F2 in 5 (19%), F1 in 9 (33%), and F0 in 2 (7%). Pearson correlation r for APRI and METAVIR was 0.48 (p<0.05). The mean APRI for F2-F4 (significant fibrosis) was 3.55±3.52, and for F0-F1 (no or mild fibrosis), it was 1.80±0.88. The mean APRI for F4 (cirrhosis) was 5.33±4.27, and for F0-F3 (non-cirrhosis), it was 1.78±0.91. From the ROC, the area under the curve for significant fibrosis and cirrhosis was 0.665 and 0.836, respectively. Conclusion: APRI was positively correlated with the METAVIR index and can be used to predict significant liver fibrosis and cirrhosis in infants with cholestasis.

Published: September 2024

Background: South Africa has a high mortality rate because of road traffic accidents (RTAs) compared to other countries.Aim: To determine the visual functions and their association with the occurrence of RTAs among vehicle drivers in the Gauteng province of South Africa.Setting: Eight driver’s license testing centres (DLTCs) in the Gauteng province.Methods: A cross-sectional study involving a multi-stage random sampling approach was conducted. Data collected using the questionnaire included participants’ demographic details. Ocular health examination included the measurement of visual acuity (VA), refractive errors, visual fields, colour vision, stereopsis, contrast and glare sensitivity.Results: A total of 579 motor vehicle drivers were enrolled in this study. Drivers who reported daily alcohol consumption had a higher risk of being involved in RTAs (odds ratio [OR] = 1.8, 95% confidence interval [95%CI] = 1.09–2.99, P = 0.02). Visual acuity (OR = 1.43, 95%CI = 0.99–2.06, P = 0.05), refractive errors (P = 0.03, χ2 = 61.57), abnormal contrast sensitivity (OR = 0.53, 95%CI = 0.31–0.93, P = 0.03) and deutan colour vision defects (P = 0.002, χ2 = 31.42) were significantly associated with RTAs. Visual field defects (OR = 0.98, 95%CI = 0.97–1.00, P = 0.09), stereopsis anomaly (OR = 1.00, 95%CI = 0.99–1.00, P = 0.35) and abnormal glare sensitivity (OR = 1.00, 95%CI = 0.99–1.01, P = 0.32) were not significantly associated with the occurrence of RTAs.Conclusion: These results suggest reviewing the visual requirements for obtaining a driver’s license by incorporating colour vision and contrast sensitivity assessment.Contribution: The study addresses a gap in the country’s current vision testing standards for driving.
