Паранеопластический синдром представляет собой клинические проявления онкологической патологии, возникающие на расстоянии от первичного очага и не являющиеся следствием метастазирования или прорастания опухоли. Понятие паранеопластический синдром охватывает большую группу заболеваний разных, как по клиническим проявлениям, так и по патогенетическим механизмам. Обязательной предпосылкой для развития является процесс канцерогенеза. При этом проявления паранеопластического синдрома часто предшествуют первым клиническим признакам онкологической патологии, поэтому звание их особенностей повышает вероятность ранней диагностики рака. В данной статье представлен случай паранеопластического синдрома в ревматологической практике.
Paraneoplastic syndrome is a clinical manifestation of oncological pathology that occurs at a distance from the primary focus and is not a consequence of metastorrhea or swelling germination. The concept of paraneoplastic syndrome covers a large group of diseases, different both in clinical manifestations and in pathogenetic mechanisms. A prerequisite for development is the process of carcinogenesis. At the same time, the manifestations of the paraneoplastic syndrome often precede the first clinical signs of oncological pathology, therefore the rank of their features increases the likelihood of early diagnosis of cancer. This article presents a case of paraneoplastic syndrome in rheumatological practice.

Published: October 2024

Abstract
Colloidal particles are applied to manufacturing in various fields such as ink, food, cosmetics, etc. It is important to study the dispersibility of colloidal particles because they are dispersed in some solvents. However, many colloidal dispersions are dark-colored, and typical methods cannot evaluate the dispersibility. Therefore, dispersibility has been evaluated by the naked eye in almost all research papers. Therefore, we have fabricated a quantitative dispersibility evaluation system (QDES) for the dark colloidal dispersion using light transparency by various light types and colors of bright lights. The obtained data were fitted with a stretched exponential function (SEF) to evaluate the dispersibility. As one of the examples of a dark colloidal particle, we chose graphene oxide (GO) which is applied to manufacturing with printing technology. From the measurement results, the red LED light is suitable for the QDES in terms of accuracy and applicability to the SEF.
Electric properties for thin films of microwave treated hydrophilic graphite fabricated by liquid–liquid interface

Published: October 2024

Abstract
This paper reports the results of an attempt to combine microwave treated hydrophilic graphite (MwHG), a new carbon material that is both hydrophilic and electrically conductive, with a new deposition method using the interface between the aqueous and organic phases, the liquid–liquid interface deposition method (L-L method). The synthesized MwHG was characterized by X-ray diffraction and Raman spectroscopy, and the deposited MwHG films were characterized by scanning electron microscopy and electrical properties. It was found that the crystallinity of MwHG was changed by changing the microwave irradiation time during the synthesis of MwHG. It was also found that the high electrical conductivity was related to the microwave irradiation time or the order in which the films were deposited. Furthermore, the surface morphology of the films consisted of agglomerations of particles of different sizes with pores, and the size of the particles decreased with the number of depositions.

Biases in Exoplanet Transmission Spectra Introduced by Limb-darkening Parametrization
Authors: Coulombe Louis-Philippe , Roy Pierre-Alexis , Benneke Björn 
Published: October 2024

Abstract
One of the main endeavors of the field of exoplanetary sciences is the characterization of exoplanet atmospheres on a population level. The current method of choice to accomplish this task is transmission spectroscopy, where the apparent radius of a transiting exoplanet is measured at multiple wavelengths in search of atomic and molecular absorption features produced by the upper atmosphere constituents. To extract the planetary radius from a transit light curve, it is necessary to account for the decrease in luminosity away from the center of the projected stellar disk, known as limb darkening. Physically motivated parametrizations of limb darkening, in particular of the quadratic form, are commonly used in exoplanet transit light-curve fitting. Here, we show that such parametrizations can introduce significant wavelength-dependent biases in the transmission spectra currently obtained with all instrument modes of the JWST, and thus have the potential to affect atmospheric inferences. To avoid such biases, we recommend the use of standard limb-darkening parametrizations with wide uninformative priors that allow for nonphysical stellar intensity profiles in the transit fits, and thus for a complete and symmetrical exploration of the parameter space. We further find that fitting the light curves at the native resolution results in errors on the measured transit depths that are significantly smaller compared to light curves that are binned in wavelength before fitting, thus potentially maximizing the amount of information that can be extracted from the data.
Modeling of Long-term Afterglow Counterparts to Gravitational Wave Events: The Full View of GRB 170817A
Authors: Ryan Geoffrey , van Eerten Hendrik , Troja Eleonora , Piro Luigi , O’Connor Brendan , Ricci Roberto 
Published: October 2024

Abstract
The arrival of gravitational wave astronomy and a growing number of time-domain-focused observatories are set to lead to an increasing number of detections of short gamma-ray bursts (GRBs) launched with a moderate inclination to Earth. Being nearby events, these are also prime candidates for very long-term follow-up campaigns and very long-baseline interferometry, which has implications for multi-messenger modeling, data analysis, and statistical inference methods applied to these sources. Here, we present a comprehensive modeling update that directly incorporates into afterglowpy astrometric observations of the GRB position, Poissonian statistics for faint sources, and modeling of a trans-relativistic population of electrons. We use the revolutionary event GW170817 to demonstrate the impact of these extensions both for the best-fit physics parameters and model selection methods that assess the statistical significance of additional late-time emission components. By including in our analysis the latest Chandra X-ray observations of GRB 170817A, we find only weak evidence (≲2σ) for a new emission component at late times, which makes for a slightly more natural fit to the centroid evolution and prediction for the external medium density.
Evidence for a Fast Soft X-Ray Wind in M82 from XMM-RGS
Authors: Boettcher Erin , Hodges-Kluck Edmund 
Published: October 2024

Abstract
Starburst wind models predict that metals and energy are primarily carried out of the disk by hot gas (T > 106 K), but the low energy resolution of X-ray CCD observations results in large uncertainties on the mass and energy loading. Here, we present evidence for a fast soft X-ray wind from the prototypical starburst galaxy M82 using deep archival observations from the Reflection Grating Spectrometer on XMM-Newton. After characterizing the complex line-spread function for the spatially extended outflow (

Alternatively, these higher energy emission lines may be dominated by shock-heated gas in the interstellar medium. Future synthesis of these measurements with performance verification observations of the E = 2−12 keV wind in M82 from the Resolve microcalorimeter on the X-ray Imaging and Spectroscopy Mission will inform the phase structure and energy budget of the hot starburst wind.
Almost All Carbon/Oxygen White Dwarfs Can Host Double Detonations
Authors: Shen Ken J. , Boos Samuel J. , Townsley Dean M. 
Published: October 2024

Abstract
Double detonations of sub-Chandrasekhar-mass white dwarfs (WDs) in unstably mass-transferring double WD binaries have become one of the leading contenders to explain most Type Ia supernovae. However, past theoretical studies of the explosion process have assumed relatively ad hoc initial conditions for the helium shells in which the double detonations begin. In this work, we construct realistic C/O WDs to use as the starting points for multidimensional double detonation simulations. We supplement these with simplified one-dimensional detonation calculations to gain a physical understanding of the conditions under which shell detonations can propagate successfully. We find that C/O WDs ≲1.0 M
⊙, which make up the majority of C/O WDs, are born with structures that can support double detonations. More massive C/O WDs require ∼10−3
M
⊙ of accretion before detonations can successfully propagate in their shells, but such accretion may be common in the double WD binaries that host massive WDs. Our findings strongly suggest that if the direct impact accretion stream reaches high enough temperatures and densities during mass transfer from one WD to another, the accreting WD will undergo a double detonation. Furthermore, if the companion is also a C/O WD ≲1.0 M
⊙, it will undergo its own double detonation when impacted by the ejecta from the first explosion. Exceptions to this outcome may explain the newly discovered class of hypervelocity supernova survivors.
Concept of a Double Tilted Rowland Spectrograph for X-Rays
Authors: Günther Hans Moritz , DeRoo Casey T. , Heilmann Ralf K. , Hertz Edward 
Published: October 2024

Abstract
High-resolution spectroscopy in soft X-rays (<2 keV) requires diffractive elements to resolve any astrophysically relevant diagnostics, such as closely spaced lines, weak absorption lines, or line profiles. The Rowland torus geometry describes how gratings and detectors need to be positioned to optimize the spectral resolving power. We describe how an on-axis Rowland geometry can be tilted to accommodate blazed gratings. In this geometry, two channels with separate optical axes can share the same detectors (double tilted Rowland spectrograph). Small offsets between the channels can mitigate the effect of chip gaps and reduce the alignment requirements during the construction of the instrument. The double tilted Rowland spectrograph concept is especially useful for subapertured mirrors, because it allows an effective use of space in the entrance aperture of a spacecraft. One mission that applies this concept is the Arcus Probe.
Dynamical Consequence of Shadows Cast to the Outer Protoplanetary Disks. I. Two-dimensional Simulations
Authors: Su Zehao , Bai Xue-Ning 
Published: October 2024

Abstract
There has been increasing evidence of shadows from scattered light observations of outer protoplanetary disks (PPDs) cast from the (unresolved) disk inner region, while in the meantime these disks present substructures of various kinds in the submillimeter. As stellar irradiation is the primary heating source for the outer PPDs, the presence of such shadows thus suggests inhomogeneous heating of the outer disk in azimuth, leading to a “thermal forcing” with dynamical consequences. We conduct a suite of idealized two-dimensional disk simulations of the outer disk with azimuthally varying cooling prescription to mimic the effect of shadows, generally assuming the shadow is static or slowly rotating. The linear response to such shadows is two-armed spirals with the same pattern speed as the shadow. Toward the nonlinear regime, we find that shadows can potentially lead to the formation of a variety of types of substructures including rings, spirals, and crescents, depending on viscosity, cooling time, etc. We have conducted systematic and statistical characterization of the simulation suite, and as thermal forcing from the shadow strengthens, the dominant form of shadow-induced disk substructures change from spirals to rings, and eventually to crescents/vortices. Our results highlight the importance of properly modeling the dynamical impact of inhomogeneous stellar irradiation, while calling for more detailed modeling incorporating more realistic disk physics.
A Multifrequency View of the Radio Phoenix in the A85 Cluster
Authors: Raja Ramij , Rahaman Majidul , Datta Abhirup , Smirnov Oleg M. 
Published: October 2024

Abstract
Radio phoenices are complex and filamentary diffuse radio sources found in both merging and relaxed clusters. The formation of these sources has been proposed to be due to adiabatic compression of old active galactic nucleus plasma in shock waves. Most of the previous spectral studies of these sources have been limited to integrated spectral indices, which were found to be very steep and show a curved spectrum. Here, we have performed a multifrequency investigation of the radio phoenix in the A85 cluster. Owing to the sensitive high-resolution observations, we found some of the finer filamentary structures that had been previously undetected. We produced resolved spectral index maps of the radio phoenix between 323, 700, and 1280 MHz. The orientation of the filaments, as well as the gradient across the spectral index maps, suggest the possible direction of the shock motion from northeast to southwest. The integrated spectrum of the radio phoenix was found to be very steep and curved toward high frequencies. Furthermore, the spectral index of the filaments was found to be less steep compared to the nonfilamentary regions, implying greater energy injection in the filaments. The observed features in the radio phoenix in the A85 cluster seem to be in support of an adiabatic shock compression mechanism.
