Published: March 2023

Creating a disease models based on real-world clinical data from the moment of diagnosis is an important task of the healthcare system, it allows to simulate the quantitative need for hospitalizations with various options for necessary treatment and calculate the approximate amount of necessary funding.

The study aimsto build a model calculating the necessary volumes of medical care and funding for inpatient treatment of patients with lung cancer.

Materials and methods.Anonymized data from the territorial compulsory medical insurance fund and the Department of high-tech medical care for all cases of lung cancer and metastases of any localization (ICD-10: C34 and C77-78) for residents of St. Petersburg, who received medical care from 2011 to 2020. Data from the population cancer registry database for all lung cancer patients in St. Petersburg since 2000.

Results.More than 75 % of hospitalizations occur within 1 year from the moment of diagnosis: 68 % — chemotherapeutic treatment, 17 % — surgery, 3 % — radiotherapy. In the first year, 1 patient with stages I and II has an average of 2 hospitalizations, III and IV — 3. The calculated by the model number of hospitalizations in the 2 236 lung cancer patients in 5 years is 7 108. Payment for inpatient care based on the tariffs of the federal fund of 2022 and the number of newly diagnosed lung cancer diagnoses for five years will cost the healthcare system 1.1 billion RUR, and more than 74 % of this amount is the cost of 1 year of treatment. During the 5 years, surgery will cost 145 million RUR, chemotherapy — more than 898 million RUR, and radiotherapy — 37 million RUR.

Conclusion.The developed on the real-world clinical data model can be used to calculate the necessary healthcare needs and its costs.

Published: March 2023

Earnings management research has a long and rich history. However, the effect of managerial ownership and audit committee financial expertise on earnings management is rarely conducted in the developing countries like Nigeria. Therefore, this study examines how managerial ownership and audit committee financial expertise on earnings management of listed manufacturing companies in Nigeria. This study used the Roychowdhury approach to measure real earnings management. Thirty-four (34) manufacturing companies out of seventy-three (73) population that were listed on the Nigerian Exchange (NGX) from 2007 to 2021 was selected as sample size. Data was gleaned from the annual financial reports of the sampled companies for this study. Descriptive statistics, Pearson correlation, and quantile regression analysis are the econometric techniques used to test the analysed data and for hypothesis testing. Results from the study showed that managerial ownership significantly affects real-earnings management. When the effect was moderated by the financial expertise of the audit committee, the effect of ownership structure on real earnings management disappears. The result from the study show that managers of manufacturing firms in Nigeria should be encouraged to own more shares in the companies they manage in order to minimize real earnings management. The evidence can theoretically serve as a solid foundation for regulatory action, notably through improving the alignment of managers' and shareholders' interests. The results from this study have important implications for regulators, who will gain from understanding how managerial ownership affects real earnings management and improve the accuracy of financial reporting. The findings will also help policymakers and academics to understand how managerial ownership affects real earnings management in Nigeria.

All cases of ALL referred to the department for remission after taking induction therapy, irrespective of age and gender were included. Relevant information wascollected on a predesigned proforma prepared in accordance with the objectives of the study.
 
Results: A total of 84 cases referred for remission were included, 56(66.7%) were males and 28 (33.3%) were females. 50(59.5%) cases were in the age range of 5-18 years. The mean with a standard deviation of the age of patients was 15+ 4 years. 75(89.3%) of the cases were classified into ALL-1) by FAB classification. 50(59.5%) of the referred cases had achieved morphological remission by bone marrow aspiration. There was a statistically significant rise in Platelet count of the remission vs non-remission cases (p-0.001). Again there was a statistically significant difference in the retic count of the cases with remission (p-0.05). We observed a statically significant downhill moderate correlation ofretic count with remission (in termsof blast count of BM aspiration) (p-0.04, r:-0.32). Platelet count also had an inverse significant correlation with remission ( p-0.01, r:-0.37).

Although the majority of Herbig Ae/Be (HAEBE) stars are likely multiple systems, relatively few multiples have been identified. We aim to create a statistically significant survey of HAEBE multiplicity as a function of stellar mass, to shed light on mixed-mass star formation. Two independent adaptive optics IR imaging surveys were conducted, between 1993 and 2007. A total of 143 stars were observed, including 126 HAEBE stars. These surveys are significantly more sensitive than previous imaging work and, combined with accurate distance and proper-motion data from GAIA Data Release 3, provide a broad survey of intermediate-mass multiplicity. We perform a statistical probability analysis to identify the likely physical companions, and analyze multiepoch observations for common proper motions. We find 250 stellar detections around 88 sample stars. Of these, 70 systems are likely multiple systems, and 42 companions around 29 systems are reported here for the first time. Correcting for completeness, we find a multiplicity fraction of 54%. Multiples are found randomly across all spectral types, but high-order multiples are more common among the hottest stars. Statistically likely companions are found at distances of up to several thousand astronomical units and ΔK magnitudes ranging from <0.1 to ∼9, although companions with ΔK < 1.5 are rare. Companions around Herbig Ae stars tend to be closer than those around Herbig Be stars. We confirm 24 proper-motion companions in 21 systems, including roughly half of the statistically very likely companions; however, many proper-motion results are inconclusive.
Spectroscopic Orbits of Subsystems in Multiple Stars. IX
Authors: Tokovinin Andrei
Published: March 2023

New spectroscopic orbits of inner subsystems in 14 hierarchies are determined from long-term monitoring with the optical echelle spectrometer, CHIRON. Their main components are nearby solar-type stars belonging to nine triple systems (HIP 3645, 14307, 36165, 79980, 103735, 103814, 104440, 105879, 109443) and five quadruples of 2 + 2 hierarchy (HIP 41171, 49336, 75663, 78163, and 117666). The inner periods range from 254 days to 18 yr. Inner subsystems in HIP 3645, 14313, 79979, 103735, 104440, and 105879 are resolved by speckle interferometry, and their combined spectro-interferometric orbits are derived here. Astrometric orbits of HIP 49336 Aa,Ab and HIP 117666 Aa,Ab are determined from wobble in the observed motion of the outer pairs. Comparison with three spectroscopic orbits found in the Gaia data release 3 archive reveals that Gaia underestimated the amplitudes (except for HIP 109443), while the periods match approximately. This work contributes new data on the architecture of nearby hierarchical systems, complementing their statistics.

We present a multiwavelength analysis of the galaxy cluster SPT-CL J0607-4448 (SPT0607), which is one of the most distant clusters discovered by the South Pole Telescope at z = 1.4010 ± 0.0028. The high-redshift cluster shows clear signs of being relaxed with well-regulated feedback from the active galactic nucleus (AGN) in the brightest cluster galaxy (BCG). Using Chandra X-ray data, we construct thermodynamic profiles and determine the properties of the intracluster medium. The cool-core nature of the cluster is supported by a centrally peaked density profile and low central entropy (

We report the multiwavelength properties of millimeter galaxies hosting X-ray detected active galactic nuclei (AGNs) from the ALMA Lensing Cluster Survey (ALCS). ALCS is an extensive survey of well-studied lensing clusters with ALMA, covering an area of 133 arcmin2 over 33 clusters with a 1.2 mm flux-density limit of ∼60 μJy (1σ). Utilizing the archival data of Chandra, we identify three AGNs at z = 1.06, 2.09, and 2.84 among the 180 millimeter sources securely detected in the ALCS (of which 155 are inside the coverage of Chandra). The X-ray spectral analysis shows that two AGNs are not significantly absorbed (

Star cluster formation in the early universe and its contribution to reionization
remains largely unconstrained to date. Here we present JWST/NIRCam imaging of
the most highly magnified galaxy known at z ∼ 6,
the Sunrise arc. We identify six young massive star
clusters (YMCs) with measured radii spanning from ∼20 down to ∼1 pc (corrected
for lensing magnification), estimated stellar masses of ∼106–7
M
⊙, and ages of 1–30 Myr based on SED fitting to photometry measured
in eight filters extending to rest frame 7000 Å. The resulting stellar mass
surface densities are higher than 1000 M
⊙ pc−2 (up to a few 105
M
⊙ pc−2), and their inferred dynamical ages qualify the
majority of these systems as gravitationally bound stellar clusters. The star
cluster ages map the progression of star formation along the arc, with two
evolved systems (≳10 Myr old) followed by very young clusters. The youngest
stellar clusters (<5 Myr) show evidence of prominent Hβ+[O iii] emission based on photometry with equivalent
widths larger than >1000 Å rest frame and are hosted in a 200 pc sized
star-forming complex. Such a region dominates the ionizing photon production
with a high efficiency

. A significant fraction of the recently formed stellar mass of
the galaxy (10%–30%) occurred in these YMCs. We speculate that such sources of
ionizing radiation boost the ionizing photon production efficiency, which
eventually carves ionized channels that might favor the escape of Lyman
continuum radiation. The survival of some of the clusters would make them the
progenitors of massive and relatively metal-poor globular clusters in the local
universe.

We observed HD 19467 B with JWST’s NIRCam in six filters spanning 2.5–4.6 μm with the long-wavelength bar coronagraph. The brown dwarf HD 19467 B was initially identified through a long-period trend in the radial velocity of the G3V star HD 19467. HD 19467 B was subsequently detected via coronagraphic imaging and spectroscopy, and characterized as a late-T type brown dwarf with an approximate temperature ∼1000 K. We observed HD 19467 B as a part of the NIRCam GTO science program, demonstrating the first use of the NIRCam Long Wavelength Bar coronagraphic mask. The object was detected in all six filters (contrast levels of 2 × 10−4 to 2 × 10−5) at a separation of 1.″6 using angular differential imaging and synthetic reference differential imaging. Due to a guide star failure during the acquisition of a preselected reference star, no reference star data were available for post-processing. However, reference differential imaging was successfully applied using synthetic point-spread functions developed from contemporaneous maps of the telescope’s optical configuration. Additional radial velocity data (from Keck/HIRES) are used to constrain the orbit of HD 19467 B. Photometric data from TESS are used to constrain the properties of the host star, particularly its age. NIRCam photometry, spectra, and photometry from the literature, and improved stellar parameters are used in conjunction with recent spectral and evolutionary substellar models to derive the physical properties of HD 19467 B. Using an age of 9.4 ± 0.9 Gyr inferred from spectroscopy, Gaia astrometry, and TESS asteroseismology, we obtain a model-derived mass of 62 ± 1 M

A Catalog of 71 Coronal Line Galaxies in MaNGA: [Ne v] Is an Effective AGN Tracer

Published: March 2023

Despite the importance of active galactic nuclei (AGNs) in galaxy evolution, accurate AGN identification is often challenging, as common AGN diagnostics can be confused by contributions from star formation and other effects (e.g., Baldwin–Phillips–Terlevich diagrams). However, one promising avenue for identifying AGNs is “coronal emission lines” (“CLs”), which are highly ionized species of gas with ionization potentials ≥100 eV. These CLs may serve as excellent signatures for the strong ionizing continuum of AGNs. To determine if CLs are in fact strong AGN tracers, we assemble and analyze the largest catalog of optical CL galaxies using the Sloan Digital Sky Survey's Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) catalog. We detect CL emission in 71 MaNGA galaxies, out of the 10,010 unique galaxies from the final MaNGA catalog, with ≥5σ confidence. In our sample, we measure [Ne v]λ3347, λ3427, [Fe vii]λ3586, λ3760, λ6086, and [Fe x]λ6374 emission and crossmatch the CL galaxies with a catalog of AGNs that were confirmed with broad-line, X-ray, IR, and radio observations. We find that [Ne v] emission, compared to [Fe vii] and [Fe x] emission, is best at identifying high-luminosity AGNs. Moreover, we find that the CL galaxies with the least dust extinction yield the most iron CL detections. We posit that the bulk of the iron CLs are destroyed by dust grains in the galaxies with the highest [O iii] luminosities in our sample, and that AGNs in the galaxies with low [O iii] luminosities are possibly too weak to be detected using traditional techniques.

We report on broadband X-ray properties of the Rabbit pulsar wind nebula (PWN) associated with the pulsar PSR J1418−6058 using archival Chandra and XMM-Newton data, as well as a new NuSTAR observation. NuSTAR data above 10 keV allowed us to detect the 110 ms spin period of the pulsar, characterize its hard X-ray pulse profile, and resolve hard X-ray emission from the PWN after removing contamination from the pulsar and other overlapping point sources. The extended PWN was detected up to ∼20 keV and is described well by a power-law model with a photon index Γ ≈ 2. The PWN shape does not vary significantly with energy, and its X-ray spectrum shows no clear evidence of softening away from the pulsar. We modeled the spatial profile of X-ray spectra and broadband spectral energy distribution in the radio to TeV band to infer the physical properties of the PWN. We found that a model with low magnetic field strength (B ∼ 10 μG) and efficient diffusion (D ∼ 1027 cm2 s−1) fits the PWN data well. The extended hard X-ray and TeV emission, associated respectively with synchrotron radiation and inverse Compton scattering by relativistic electrons, suggest that particles are accelerated to very high energies (≳500 TeV), indicating that the Rabbit PWN is a Galactic PeVatron candidate.

The 3D extinction and structure are studied for the Taurus, Orion, Perseus, and California molecular clouds based on the LAMOST spectroscopy. Stellar color excess is calculated with the intrinsic color index derived from the atmospheric parameters in the LAMOST DR8 catalog and the observed color index in the Gaia EDR3 and the 2MASS PSC. In combination with the distance from the Gaia EDR3 parallax, the 3D dust extinction maps are retrieved in the color excesses

with an uncertainty of ∼0.03 mag and ∼0.07 mag respectively. The extinction maps successfully separate the clouds that overlap in the sky area and manifest the structure of the individual cloud. Meanwhile, a bow-like structure is found with a distance range from 175 to 250 pc, half of which is a part of the Per-Tau Shell in similar coordinates and distance while the other half is not. Three low-extinction rings are additionally discovered and briefly discussed.
Constraining a Model of the Radio Sky below 6 MHz Using the Parker Solar Probe/FIELDS Instrument in Preparation for Upcoming Lunar-based Experiments

Published: March 2023

We present a Bayesian analysis of data from the FIELDS instrument on board the Parker Solar Probe (PSP) spacecraft with the aim of constraining low-frequency (≲6 MHz) sky in preparation for several upcoming lunar-based experiments. We utilize data recorded during PSP’s coning roll maneuvers, in which the axis of the spacecraft is pointed 45° off of the Sun. The spacecraft then rotates about a line between the Sun and the spacecraft with a period of 24 minutes. We reduce the data into two formats: roll-averaged, in which the spectra are averaged over the roll, and phase-binned, in which the spectra are binned according to the phase of the roll. We construct a forward model of the FIELDS observations that includes numerical simulations of the antenna beam, an analytic emissivity function of the galaxy, and estimates of the absorption due to free electrons. Fitting 5 parameters, we find that the roll-averaged data can be fit well by this model, and we obtain posterior parameter constraints that are in general agreement with previous estimates. The model is not, however, able to fit the phase-binned data well, likely due to limitations such as the lack of nonsmooth emission structure at both small and large scales, enforced symmetry between the northern and southern galactic hemispheres, and large uncertainties in the free electron density. This suggests that significant improvement in the low-frequency sky model is needed in order to fully and accurately represent the sky at frequencies below 6 MHz.
Observational Evidence for Large-scale Gas Heating in a Galaxy Protocluster at z = 2.30
Authors: Dong Chenze , Lee Khee-Gan , Ata Metin , Horowitz Benjamin , Momose Rieko
Published: March 2023

We report a z = 2.30 galaxy protocluster (COSTCO-I) in the COSMOS field, where the Lyα forest as seen in the CLAMATO IGM tomography survey does not show significant absorption. This departs from the transmission–density relationship (often dubbed the fluctuating Gunn–Peterson approximation; FGPA) usually expected to hold at this epoch, which would lead one to predict strong Lyα absorption at the overdensity. For comparison, we generate mock Lyα forest maps by applying the FGPA to constrained simulations of the COSMOS density field and create mocks that incorporate the effects of finite sight-line sampling, pixel noise, and Wiener filtering. Averaged over r = 15 h
−1 Mpc around the protocluster, the observed Lyα forest is consistently more transparent in the real data than in the mocks, indicating a rejection of the null hypothesis that the gas in COSTCO-I follows the FGPA (p = 0.0026, or 2.79σ significance). It suggests that the large-scale gas associated with COSTCO-I is being heated above the expectations of the FGPA, which might be due to either large-scale AGN jet feedback or early gravitational shock heating. COSTCO-I is the first known large-scale region of the IGM that is observed to be transitioning from the optically thin photoionized regime at cosmic noon to eventually coalesce into an intracluster medium (ICM) by z = 0. Future observations of similar structures will shed light on the growth of the ICM and allow constraints on AGN feedback mechanisms.
Meet the Parents: The Progenitor Binary for the Supermassive Black Hole Candidate in E1821+643
Authors: Paynter James , Thrane Eric
Published: March 2023

The remnants of binary black hole mergers can be given recoil kick velocities up to 5000 km s−1 due to anisotropic emission of gravitational waves. E1821+643 is a recoiling supermassive black hole candidate with spectroscopically offset, broad emission lines, consistent with motion of the black hole at ∼2100 km s−1 along the line of sight relative to its host galaxy. This suggests a recoil kick of ∼2200 km s−1. Such a kick is powerful enough to eject E1821+643 from its M

This suggests that the progenitor for E1821+643 merged in hot gas, which is thought to provide an environment where spin alignment from accretion proceeds slowly relative to the merger timescale. We infer that E1821+643, if it is a recoiling black hole, is likely to be a rapidly rotating black hole with a dimensionless spin of χ = 0.92 ± 0.04. A 2.6 × 109

Published: March 2023

We present a curated sample of 6688 resolved binaries containing M and L dwarf companions within 400 pc of the Sun, including 121 systems within 100 pc. These sources were selected from the Gaia EDR3 compilation of El-Badry et al., and further vetted using photometric and astrometric data from SDSS, Pan-STARRS, 2MASS, UKIDSS, and WISE, as well as visual examination of imaged fields. Only 13% of these systems were reported as co-moving pairs prior to Gaia, and only 4% of the primaries and 1% of the secondaries have published spectral classifications, including just 9 of 109 late-M and L dwarf secondaries within 100 pc. Follow-up of this expanded low-mass companion sample will provide valuable benchmark systems for precisely calibrating empirical diagnostics of the physical properties of the lowest-mass stars and brown dwarfs.
Mammal use of underpasses to cross Route 606 in Guacimal, Costa Rica
Authors: Terner Eleanor R.
Published: March 2023

Roads severely affect the health of ecosystems across the globe by fragmenting habitats, reducing population connectivity, and increasing animal mortality. Wildlife underpasses allow for increased road permeability–the ability for animals to safely cross the road. Despite growing success in other regions, underpass usage in Central America is critically under-researched. In this study, I monitored two dry circular culverts and two unfenced tunnels on Route 606 in Guacimal, Costa Rica, from 22 November to 6 December 2021 using 14 camera traps to assess which species used them to cross. Twelve species used the culverts and tunnels for a total of 108 individual crossings. The tunnels were used, in descending order, by agouti (Dasyprocta punctata), opossum (Didelphis marsupialis), dog (Canis familiaris), armadillo (Dasyous novemcinctus), cat (Felis catus), Norway rat (Dasypus novemcinctus), ocelot (Leopardus pardalis), squirrel (Sciurus variegatoides), tamandua (Tamandua mexicana), and coati (Nasua narica). The circular tunnel, Tunnel 1, was used more frequently and by a greater diversity of species than observed in the square tunnel, Tunnel 2. The two smaller culverts were used by opossum (Didelphis marsupialis), cat (Felis catus), rat opossum (Micoureus alstoni), and Watson’s climbing rat (Tylomus watsoni). Culvert 2 was used more frequently; however, Culvert 1 was used by a greater diversity of species. Species such as coyote (Canis latrans) and gray fox (Urocyon cinereoargenteus) were captured in the surrounding fragments but not using any underpass. This study highlights wildlife underpasses as a critical strategy for biological conservation in Costa Rica though improved road safety and habitat connectivity.

 
Physical stability and dissolution of ketoprofen nanosuspension formulation: Polyvinylpyrrolidone and Tween 80 as stabilizers
Authors: Ismanelly Hanum Tengku , Nasution Azizah , Sumaiyah Sumaiyah , Bangun Hakim
Published: March 2023

This study was conducted to improve the dissolution of ketoprofen in nanosuspensions. Ketoprofen nanosuspensions were prepared by a solvent evaporation method using polyvinylpyrrolidone (PVP) and Tween 80 as stabilizers at varied ratios with ketoprofen. Ethanol was used as a solvent for ketoprofen. Physical stability and dissolution of the produced ketoprofen nanosuspensions and conventional suspension were analyzed and compared. The parameters evaluated for their stability for a three-month period were pH, appearance, odor, color, particle size, zeta potential, polydispersity index (PI), and dissolution compared with ketoprofen suspension. Ketoprofen and PVP ratios of 1:1 and 1:1.5 had nano-scale particle sizes of 78.47±0.61 and 156.9±1.55, respectively. These nanosuspensions had stable pH, appearance, odor, color, particle size, and PI at room temperature. The dissolution rates of ketoprofen nanosuspensions were higher compared to that of ketoprofen conventional suspension. PVP and Tween 80 improved ketoprofen nanosuspension dissolution and was stable at room temperature for three months.
Le sens clinique des stéréotypies dans l’autisme
Authors: Moisan-Ehrwein Anne-Lise , Jean-Dit-Pannel Romuald
Published: March 2023

Les comportements stéréotypés des personnes atteintes de troubles du spectre autistique (TSA) questionnent et sont souvent considérés comme entravant tout travail éducatif et thérapeutique. L’objectif de cet article est de proposer une réflexion sur les différent(s) sens clinique(s) que peuvent prendre les stéréotypies afin de penser la prise en charge globale du sujet autiste et plus spécifiquement son accompagnement psychothérapeutique. Les stéréotypies, comportements répétitifs à caractère restreint (nous pourrions parler de « détournement sensoriel »), excluant l’autre, peuvent porter sur le langage, sur un ou plusieurs objets, avec des manifestations motrices répétitives (provoquer inlassablement le bruit d ’un objet, faire tourner la roue d’une petite voiture sans cesse, tourner autour d’une table, auto-agressions, etc.). Après avoir proposé différents liens ordinaires inhérents à la clinique du bébé et aux théorisations psychanalytiques, nous présenterons deux observations cliniques dans des contextes de TSA.
Job involvement and valuation of job resources: The mediating effect of satisfaction with job resources
Authors: Gil Alfonso J. , Cegarra-Navarro Juan Gabriel , Tobias Claudia , Marin-Malumbres Claudia
Published: March 2023

Purpose: This paper has two objectives: the first, to analyse the relationship between job involvement and valuation of job resources; the second, to analyse the mediating effect of satisfaction with job resources on the relationship between job involvement and employees’ valuation of job resources.Design/methodology/approach: The survey was used as a research methodology. The participants correspond to a sample of 225 employees in Spain.Findings: The hypotheses are positively contrasted. Job involvement is positively related to valuation of job resources, and satisfaction with job resources mediates the relationship between job involvement and valuation of job resources. The results of this work indicate that the most involved employees give greater importance to job resources.Originality/value: This paper evidences the relationship between job involvement and the importance that employees attribute to job resources. Therefore, this research advances the job demands-resources model, as it suggests that employees’ high involvement in their job leads to greater involvement of resources, which is related to employees’ psychological contract.

Published: March 2023

This work evaluates the fractional complex Ginzburg-Landau equation in the sense of truncated M- fractional derivative and analyzes its soliton solutions and other new solutions in the appearance of a detuning factor in non-linear optics. The multiple, bright, and bright-dark soliton solutions of this equation are obtained using the modified $\left({{{G'} / {{G^2}}}} \right)$ and $\left({{1 / {G'}}} \right) - $expansion methods. The equation is evaluated with Kerr law, quadratic –cubic law and parabolic law non-linear fibers. To shed light on the behavior of solitons, the graphical illustrations in the form of 2D and 3D of the obtained solutions are represented for different values of various parameters. All of the solutions have been verified by substitution into their corresponding equations with the aid of a symbolic software package. The various forms of solutions to the aforementioned nonlinear equation that arises in fluid dynamics and nonlinear processes are presented. Moreover, we guarantee that all the solutions are new and an excellent contribution in the existing literature of solitary wave theory.
