AbstractBackground,Minibreak intervention may solve asthenopia which has a main problem among workers using VDT. Asthenopia is measured with near point convergence (NPC). The purpose of this study was to determine convergence power difference that mini break produces between workers using standard VDT and widescreen VDT. Methods, Sixty six workers were divided into four groups: minibreak and no minibreak intervention in standard VDT users and widescreen VDT users. The difference of NPC before and after 4 hours of VDT exposure and 4 hours of exposure with a 15 minute minibreakwere measured in all groups using RAF ruler. Results, Minibreak intervention resulted in a significant difference of convergence power between workers using standard VDT (p=0.000) and widescreen VDT (p=0.000). But the differences of convergence between standard VDT and widescreen VDT were not significant in those given minibreak (p=0.9694) and those not given (p=0.6251). Conclusion, Mini break intervention produced significant differences in convergence power between both groups but the size of the VDT had no effect. Keywords: Asthenopia, VDT, near point convergence, mini break AbstrakLatar Belakang, Mini break dapat menjadi solusi untuk kelelahan mata yang menjadi masalah utama pada pekerja dengan pekerjaan menggambar menggunakan VDT. Kelelahan mata dapat diukur dengan mengukurnear point convergence (NPC). Tujuan penelitian ini untuk mengetahui perbedaan NPC yang dihasilkan oleh mini break pada pekerja yang menggunakan VDT standar dan wide screen. Metode, Enam puluh enam pekerja dibagi menjadi empat kelompok: mini break dan tanpa mini break pada pekerja VDT standar dan wide screen. Perbedaan NPC sebelum dan sesudah pajanan VDT selama 4 jam terus-menerus tanpa mini break dan pajanan selama 4 jam dengan mini break 15 menit di tengah-tengah diukur pada semua grup menggunakan RAF ruler. Hasil, Intervensi mini break menghasilkan perbedaan bermakna pada kekuatan konvergensi antara pekerja yang menggunakan VDT standar (p=0.000) dan VDT widescreen (p=0.000). Namun perbedaan konvergensi antara VDT standar dan widescreen tidak berbeda bermakna pada grup yang diberikan mini break (p=0.9694) dan tanpa mini break (p=0.6251). Kesimpulan, Intervensi mini break menghasilkan kekuatan konvergensi yang berbeda antara dua kelompok pekerja, namun hal tersebut tidak dipengaruhi oleh ukuran VDT.

Efficiency is a critical indicator of a company's performance, reflecting its ability to utilize resources effectively. Previous studies on efficiency have often presented inconsistent findings regarding the influence of financial ratios, corporate governance, and business risk. This study aims to analyze the effect of financial ratios (leverage, liquidity, profitability), good corporate governance, and business risk on the efficiency of manufacturing companies in Indonesia listed on the Indonesia Stock Exchange from 2017 to 2023. The study uses a sample of 67 manufacturing companies selected through purposive sampling, yielding 469 observations over seven years. Panel data regression analysis was employed using EViews 9 software to test the hypotheses. The results indicate that leverage and business risk positively influence company efficiency, while liquidity, profitability, and governance do not show a significant effect. These findings suggest that financial decision-making and risk management play a pivotal role in enhancing efficiency. The study highlights the importance of managing leverage and mitigating business risks to optimize efficiency. Investors should consider these factors when evaluating potential investments. Future research should incorporate additional variables to provide a more comprehensive understanding of efficiency determinants.
Upper Limits on Stellar Companions to the Kepler-34 and Kepler-35 Systems

Published: February 2025

Abstract
We obtained new spectra of Kepler-34 and Kepler-35 with Keck-HIRES—nearly a decade after these systems were originally characterized with this spectrograph and other instruments—to search for radial velocity (RV) trends from a potential third stellar-mass companion at long periods. For Kepler-34, we rule out coplanar stellar masses as low as 0.12M
⊙ at an orbital period of ≲52 yr. For Kepler-35, we rule out stellar masses of 0.13M
⊙ at orbital periods of ≲55 yr. Highly stable, extreme precision RV instruments, as well as improved methodologies in characterizing double-lined spectroscopic binaries that come with these new instruments, will provide an opportunity to push these mass limits lower in the future.
Multimessenger Probes of Supermassive Black Hole Spin Evolution

Published: February 2025

Abstract
Using the semianalytic model Serotina, we investigate the cosmic spin evolution of supermassive black holes (SMBHs) incorporating recent results from general-relativistic magnetohydrodynamics simulations of spin-down from relativistic jets. We compare several variations of our model with compiled black hole (BH) spin measurements derived from X-ray reflection spectroscopy, correcting for a bias arising from the spin-dependent radiative efficiency of accretion flows. We show that the observed spin distribution is in agreement with a model that includes jet-driven spin-down, a key mechanism that acts to modulate spins across cosmic time at both high and very low specific accretion rates. The data also clearly prefer models with coherent accretion over models in which accretion disks rapidly switch from prograde to retrograde. We further predict spin distributions accessible via spatially resolved event horizons by the next-generation Event Horizon Telescope and Black Hole Explorer, as well as gravitational waves by the Laser Interferometer Space Antenna (LISA), each of which offers unique and distinct windows into the population of spinning BHs. Jet-driven spin-down is most strongly imprinted on the abundance of very highly spinning objects in our model. In addition, we show that the spin distribution sampled by LISA events may contain a signature of the natal spin distribution of heavy seeds, but not of light seeds, offering additional discrimination between these seeding pathways. Spin distributions from these future observed samples can be used to constrain the detailed physical properties of the accretion flow on horizon scales around SMBHs.

Abstract
We present a detailed analysis of an extragalactic slow classical nova in M31 exhibiting multiple peaks in its light curve. Spectroscopic and photometric observations were used to investigate the underlying physical processes. Shock-induced heating events resulting in the expansion and contraction of the photosphere are likely responsible for the observed multiple peaks. Deviation of the observed spectrum at the peak from the models also suggests the presence of shocks. The successive peaks occurring at increasing intervals could be due to the series of internal shocks generated near or within the photosphere. Spectral modeling suggests a low-mass white dwarf (WD) accreting slowly from a companion star. The ejecta mass, estimated from spectral analysis, is ~10−4
M
⊙, which is typical for a slow nova. We estimate the binary, by comparing the archival Hubble Space Telescope data and eruption properties with stellar and nova models, to comprise a 0.65 M
⊙ primary WD and a K iii cool evolved secondary star.
