Abstract: Relevance. Evidence exists that infrarenal aortic aneurisms and aortoiliac occlusive disease in women are different than in men in terms of anatomical features and more severe clinical course. Gender differences in histopathology of abdominal aorta are not fully studied.The objective was to study gender based differences in histopathology of abdominal aorta in patients with aortic aneurisms and aortoiliac occlusive disease.Methods and materials. The study included 96 biopsy specimens from 71 patients with aorto-iliac lesions (23 women and 48 men). A number of morphological characteristics and expression of matrix metalloproteinase 9 (MMP-9) were analyzed. The data obtained were processed statistically.Results. Adventitial infiltrate and medial sclerosis are more intense in the aneurysm than in occlusive-stenotic lesions, differences in the grade of fibrosis were proven only in men. Regardless of the patients’ gender, adventitial infiltration is denser in the aneurysmal body than in the neck; other changes in the anatomic parts of the aneurysm are similar. MMP-9 expression in the adventitia in the aneurysmal neck is higher in women, than in men. MMP-9 expression in the media and adventitia is higher in men with aneurysm, then with occlusive or stenotic lesion. Almost all indices of the aortic wall remodeling and MMP-9 expression correlate with each other in men with the aneurysm, in contrast to women.Conclusion. Gender based features in histopathology of abdominal aorta and the degree of their correlation may determine differences in the anatomy and course of abdominal aortic aneurysm and aortoiliac occlusive disease in women and men.

2. On the issue of critical arterial stenosis

Author: A. A. Suprunovich, A. Ya. Bedrov, A. A. Vrabiy, A. A. Moiseev, A. V. Baykova, R. V. Kalmykova, and A. S. Dolzhikova
Subjects: critical stenosis, hemodynamically significant stenosis, ischemia, atherosclerosis, angiography, functional test, Medicine (General), R5-920
Abstract: Cardiovascular disease (CVD) is the leading cause of death worldwide. The main contribution to the structure of mortality from CVD is made by atherosclerosis. Indications for surgical treatment of patients with diseases caused by atherosclerotic lesions of the arteries are set taking into account the degree of their stenosis. Angiography has been considered the gold standard for screening patients with CVD for many years. Numerous studies carried out over the past several decades have revealed the weak side of this method in assessing the significance of borderline stenosis. Therefore, to analyze such changes, functional tests were introduced to clarify the indications for surgical intervention. Currently, criteria for the significance of stenosis of the iliac, renal and coronary arteries have been determined. The significance of stenosis of the arteries supplying the brain and intestines is still a matter of debate and requires further study.

3. Exceptional swallowtail degeneracies in driven-dissipative quadrature squeezing

Author: Blinova, Polina, Moiseev, Evgeny, and Wang, Kai
Subjects: Quantum Physics, Physics - Optics
Abstract: We show that swallowtail catastrophe consisting of various-order non-Hermitian and Hermitian degeneracies naturally exists in the dynamics of two-mode driven-dissipative quadrature squeezing systems that break pseudo-Hermiciticy by judiciously engineered losses. We reveal that the swallowtail degeneracy structure enables nontrivial braiding of complex eigenvalues by looping around an exceptional line in the parameter space. Our findings provide a comprehensive understanding of the degeneracy geometry in two-mode driven-dissipative bosonic quadratic systems, opening new pathways toward topologically nontrivial control of Gaussian states., Comment: 5 pages main text, 10 pages supplementary material

4. Optical quantum memory on macroscopic coherence

Author: Moiseev, S. A., Gerasimov, K. I., Minnegaliev, M. M., and Moiseev, E. S.
Subjects: Quantum Physics, Physics - Applied Physics, Physics - Optics
Abstract: We propose a quantum memory based on the pre-created long-lived macroscopic quantum coherence. It is shown that the proposed approach provides new physical properties and methods for retrieval of the signal light fields and improvement of the basic parameters of quantum memory. We demonstrate how the pre-created coherence can enable quantum storage with low quantum noise, programmable and on demand retrieval of signal light fields in atomic ensembles with natural inhomogeneous broadening. The feasibility of implementing this proposal in various crystals doped with rare earth ions, as well as in atomic gases with a Raman transition indicates a new way for the development of optical quantum memory.

Abstract: Neutral hydrogen (HI) is the primary component of the cool interstellar medium (ISM) and is the reservoir of fuel for star formation. Owing to the sensitivity of existing radio telescopes, our understanding of the evolution of the ISM in galaxies remains limited, as it is based on only a few hundred galaxies detected in HI beyond the local Universe. With the high sensitivity of the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we carried out a blind HI search, the FAST Ultra-Deep Survey (FUDS), which extends to redshifts up to 0.42 and a sensitivity of 50 $\rm \mu Jy \cdot beam^{-1}$. Here, we report the first discovery of six galaxies in HI at $z>0.38$. For these galaxies, the FAST angular resolution of $\sim\,4'$ corresponds to a mean linear size of $\sim1.3\,h_{70}^{-1}\,$Mpc. These galaxies are among the most distant HI emission detections known, with one having the most massive HI content ($10^{10.93 \pm 0.04}~h_{70}^{-2}\, \rm M_\odot$). Using recent data from the DESI survey, and new observations with the Hale, BTA, and Keck telescopes, optical counterparts are detected for all galaxies within the 3-$\sigma$ positional uncertainty ($0.5\,h_{70}^{-1}\,$Mpc) and $\rm 200\,km \cdot s^{-1}$ in recession velocity. Assuming that the dominant source of HI is the identified optical counterpart, we find an evidence of evolution in the HI content of galaxies over the last 4.2 Gyr. Our new high-redshift HI galaxy sample provides the opportunity to better investigate the evolution of cool gas in galaxies. A larger sample size in the future will allow us to refine our knowledge of the formation and evolution of galaxies., Comment: 14 pages, 6 figures, 3 tables

Abstract: We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected rotation ephemerides are achieved. A further dozen optical and/or X-ray binary systems colocated with LAT sources also likely harbor gamma-ray MSPs. This catalog thus reports roughly 340 gamma-ray pulsars and candidates, 10% of all known pulsars, compared to ≤11 known before Fermi. Half of the gamma-ray pulsars are young. Of these, the half that are undetected in radio have a broader Galactic latitude distribution than the young radio-loud pulsars. The others are MSPs, with six undetected in radio. Overall, ≥236 are bright enough above 50 MeV to fit the pulse profile, the energy spectrum, or both. For the common two-peaked profiles, the gamma-ray peak closest to the magnetic pole crossing generally has a softer spectrum. The spectral energy distributions tend to narrow as the spindown power $\dot{E}$ decreases to its observed minimum near 10 ^33 erg s ^−1 , approaching the shape for synchrotron radiation from monoenergetic electrons. We calculate gamma-ray luminosities when distances are available. Our all-sky gamma-ray sensitivity map is useful for population syntheses. The electronic catalog version provides gamma-ray pulsar ephemerides, properties, and fit results to guide and be compared with modeling results.

Abstract: The ComPair gamma-ray telescope is a technology demonstrator for a future gamma-ray telescope called the All-sky Medium Energy Gamma-ray Observatory (AMEGO). The instrument is composed of four subsystems, a double-sided silicon strip detector, a virtual Frisch grid CdZnTe calorimeter, a CsI:Tl based calorimeter, and an anti-coincidence detector (ACD). The CsI calorimeter's goal is to measure the position and energy deposited from high-energy events. To demonstrate the technological readiness, the calorimeter has flown onboard a NASA scientific balloon as part of the GRAPE-ComPair mission and accumulated around 3 hours of float time at an altitude of 40 km. During the flight, the CsI calorimeter observed background radiation, Regener-Pfotzer Maximum, and several gamma-ray activation lines originating from aluminum.

8. An improvement of degree-based hashing (DBH) graph partition method, using a novel metric

Author: Mastikhina, Anna, Senkevich, Oleg, Sirotkin, Dmitry, Demin, Danila, and Moiseev, Stanislav
Subjects: Computer Science - Data Structures and Algorithms
Abstract: This paper examines the graph partition problem and introduces a new metric, MSIDS (maximal sum of inner degrees squared). We establish its connection to the replication factor (RF) optimization, which has been the main focus of theoretical work in this field. Additionally, we propose a new partition algorithm, DBH-X, based on the DBH partitioner. We demonstrate that DBH-X significantly improves both the RF and MSIDS, compared to the baseline DBH algorithm. In addition, we provide test results that show the runtime acceleration of GraphX-based PageRank and Label propagation algorithms.

Subjects: infrarenal aortic aneurysm, internal iliac artery, buttock claudication, computed tomography, perfusion tomography, Surgery, RD1-811
Abstract: The OBJECTIVE was to study the patency of the internal iliac artery and its effect to gluteus muscles blood supply and frequency of buttock claudication occurrence in the remote period after open infrarenal aortic aneurysm repair. MATERIAL AND METHODS. Examination of 37 patients after open infrarenal aortic aneurysm repair included collection of complaints, anamnesis, making CT scan with contrast and pelvic perfusion tomography. These methods allowed to assess the patency of the prosthesis and iliac arteries, calculate average blood flow rate in buttock muscles and frequency of buttock claudication occurrence depending on the lesion of the internal iliac arteries. RESULTS. Five-year patency of the internal iliac artery was 93 %. In case of passable internal iliac artery, the average blood flow rate in the ipsilateral buttock muscles was authentically higher than the same indicator in groups with stenotic or occlusive lesion of the internal iliac artery and its branches. In case of the disturbed internal iliac artery patency, the frequency of occurrence of the buttock claudication in the same side reached 50 %. CONCLUSION. High five-year internal iliac artery patency after open infrarenal aortic aneurysm repair attested the necessity of preservation the main blood flow in these arteries during the open infrarenal aortic aneurysm repair for the purpose of buttock claudication prevention. The CT scan allowed to evaluate the internal iliac artery patency and the average blood flow rate in the buttock muscles through perfusion tomography method which was necessary for differential diagnosis of the buttock claudication syndrome.

Abstract: Aim. To assess the results of transcatheter aortic valve implantation (TAVI) in comparison with open surgery for aortic stenosis in patients over 75 years old. Material and methods. We analyzed the results of 33 operations of aortic valve replacement in patients with aortic stenosis performed in the Moscow Municipal Clinical Hospital No. 15 in the period from June 2012 to September 2017. The first group included 21 TAVI operations. In 15 patients TAVI was performed through the femoral artery, 6 — transthoracic through the cardiac apex. All patients with transcatheter intervention were implanted with SAPIEN valves. In the postoperative period all patients showed a decrease in the systolic pressure gradient on the valve to 9,8±4,06 mm Hg. Aortic valve area after the operation has increased on average from 0,72±0,1 cm2 to 1,9±0,3 cm2. For comparison, a control group of 12 patients who underwent aortic valve replacement under cardiopulmonary bypass was formed. All patients had a high operative risk. Euroscore II 6,3±4,9, STS 5,2±3,4.Results. There were no cases of death in the TAVI group. These patients had the following postoperative complications: 3 patients (13,6%) — complete atrioventricular block, which required permanent pacemaker implantation; it was a significantly more frequent complication of transcatheter interventions. Less frequently in the postoperative period patients had severe acute cardiovascular failure (p=0,001), acute renal failure (p=0,05), paroxysmal atrial fibrillation (p=0,001). The volume of intraoperative blood loss was significantly less in the TAVI group: 147,6±84,4 ml and 666,7±322,9 ml (p=0,05). Mortality in the surgical group was 33% (4 patients). In the surgical group in 2 cases the cause of death was multiple organ failure, in two cases — acute cardiovascular failure. Patients from this group patients had the following postoperative complications: bleeding requiring a resternotomy — 2 (16,7%), pneumonia — 1 (8,3%), heart failure in the postoperative period, requiring prolonged cardiotonic support — 9 (75%), one patient underwent mechanical hemodynamic support, renal failure requiring renal replacement therapy in one patient.Conclusion. Even though surgical aortic valve replacement is the “gold standard” for treating patients with aortic stenosis, the results of operations in the older age group is not sufficient due to the high frequency of postoperative complications. TAVI, proposed by Cribier A, et al. in 2002, gives better results in patients over 75 age group due to the lower incidence of complications in the postoperative period, less intraoperative blood loss. We suppose that it is an alternative for patients of the older age group and high operative risk.

Abstract: We present the results of the optical identification and spectroscopic redshift measurements of 216 galaxy clusters detected in the SRG/eROSITA all-sky X-ray survey. The spectroscopic observations were performed in 2020-2023 with the 6-m BTA telescope at the Special Astrophysical Observatory of the Russian Academy of Sciences, the 2.5-m telescope at the Caucasus Mountain Observatory of the Sternberg Astronomical Institute of the Moscow State University, the 1.6-m AZT-33IK telescope at the Sayan Solar Observatory of the Institute of Solar-Terrestrial Physics of the Siberian Branch of the Russian Academy of Sciences, and the 1.5-m Russian-Turkish telescope (RTT-150) at the T\"{U}B\.{I}TAK Observatory. For all of the galaxy clusters presented here the spectroscopic redshift measurements have been obtained for the first time. Of these, 139 galaxy clusters have been detected for the first time in the SRG/eROSITA survey and 22 galaxy clusters are at redshifts $z_{spec} \gtrsim 0.7$, including three at $z_{spec} \gtrsim 1$. Deep direct images with the rizJK filters have also been obtained for four distant galaxy clusters at $z_{spec} > 0.7$. For these observations the most massive clusters are selected. Therefore, most of the galaxy clusters presented here most likely will be included in the cosmological samples of galaxy clusters from the SRG/eROSITA survey.

Abstract: We identify a fading AGN SDSS J220141.64+115124.3 from the internal Product Launch-11 (MPL-11) in Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey. The central region with a projected radius of $\sim$2.4 kpc is characterized as LINER-like line ratios while the outskirts extended to $\sim$15 kpc show Seyfert-like line ratios. The [OIII]$\lambda$5007 luminosity of the Seyfert regions is a factor of 37 (2) higher than the LINER regions without (with) dust attenuation correction, suggesting that the AGN activity decreases at least $\sim$8 $\times$ 10$^3$ yrs ($\sim$2.4 kpc/light-speed) ago. We model the emission line spectra in the central region with double Gaussian components (a narrow core and a broad wing) and analyze the properties of each component. The narrow core component mostly co-rotates with the stellar disc, whereas the broad wing component with a median of the velocity dispersion $\sim$300 km s$^{-1}$ is related to a wind outflow. The kinematic position angle (PA) of the ionized gas shows a $\sim$20{\deg} twist from the galaxy center to 1.5 effective radius. The median of the PA difference between the gas and stellar components is as large as $\sim$50{\deg} within 0.4 effective radius. The tidal feature in DESI image and star-gas misalignment suggest this galaxy is a merger remnant. Combining all these observational results as well as public available X-ray and MIR luminosities, we confirm this is a fading AGN, the merger process kick-started the central engine to quasar phase which ionized gas composed of tidal debris, and now the activity of the central black hole decreases. The discontinuity in [OIII]$\lambda$5007 flux and EQW maps is due to multiple AGN outbursts triggered by merger remnant gas inflows., Comment: Accepted for publication in MNRAS. 12 pages, 10 figures, 1 table

Abstract: In this Letter, we report a first experimental realization of bright ultra-broadband (180 THz) fiber-based biphoton source with widely spectrally separated signal and idler photons. Such a two-photon source is realized due to the joint use of broadband phase-matching of interacting light waves and high optical nonlinearity of a silica-core photonic crystal fiber. The high performance of the developed fiber source identifies it as an important and useful tool for a wide range of optical quantum applications.

15. The TELPERION survey for extended emission regions around AGN: a strongly-interacting and merging galaxy sample

Author: Keel, William, Moiseev, Alexei, Uklein, Roman, and Smirnova, Aleksandrina
Subjects: Astrophysics - Astrophysics of Galaxies
Abstract: We present the results of a search for Extended Emission-Line Regions (EELRs) ionized by extant or recently-faded active galactic nuclei (AGN), using [O III] narrowband imaging and spectroscopic followup. The sample includes 198 galaxies in 92 strongly interacting or merging galaxy systems in the range z=0.009-0.0285. Among these, three have EELRs extended beyond 10 kpc in projection from the nucleus detected in previous studies. We identify a single new distant emission region, projected 35 kpc from UGC 5941. Our optical spectrum does not detect He II, but its strong-line ratios put this in the same class as securely characterized EELR clouds. The nucleus of UGC 5941 is dominated by recent star formation, preventing detection of any weak ongoing AGN. Overall counts of distant EELRs in this and the previous TELPERION samples give incidence 2-5% depending on galaxy and AGN selection, 20-50 times higher than the Galaxy Zoo EELR survey with its higher surface-brightness threshold and much larger input sample. AGN in interacting and merging systems have an increased detection rate $12+/-6$%, while none are detected around noninteracting AGN. Some of these AGN are at luminosity low enough to require additional X-ray or far-infrared information to tell whether the EELR ionization level suggests long-term fading., Comment: Submitted to MNRAS; version including response to review comments

Abstract: Planetary nebulae are one of the final stages in the evolution of low and intermediate mass stars. They occur in a variety of shapes. Older and fainter ones are generally more difficult to identify because of the lower surface brightness. This paper reports the serendipitous discovery of a new faint Galactic planetary nebula (PN), during a campaign to identify dwarf galaxies, companions of the spiral galaxy NGC 2403. We aim at confirming the nature as PN of a diffuse object identified in the Camelopardalis constellation. We obtained narrow-band filter images and spectra of the nebula and its central star with amateur and professional telescopes having diameters from 20 cm to 6 m. We detected a dense triangular nebula, surrounded by an elliptical region, named Cam nebula. They are part of a larger and fainter circular nebular structure, named TBG-1, at the centre of which we have identified the possible central star, a white dwarf with a temperature of about 22 000 K. The analysis of the spectrum made it possible to measure the physical characteristics of the nebula, in particular its electronic density and temperature. Analysis of the images, of the spectra of the nebula and of the central star confirm the PN nature of TBG-1, located at the distance of about 1 kpc. This work reaffirms the potential for fruitful collaborations between astronomers and amateur astronomers in the detection and study of new objects., Comment: Sumbmitted to A&A, 8 pages, 12 figures.

Abstract: We present a study of the nearby low-metallicity dwarf galaxy IC 1613, focusing on the search for massive stars and related feedback processes, as well as for faint supernova remnants (SNR) in late stages of evolution. We obtained the deepest images of IC 1613 in the narrow-band H{\alpha}, He II and [S II] emission lines and new long-slit spectroscopy observations using several facilities (6-m BTA, 2.5m SAI MSU, and 150RTT telescopes), in combination with the multi-wavelength archival data from MUSE/VLT, VLA, XMM-Newton, and Swift/XRT. Our deep narrow-band photometry identifies several faint shells in the galaxy, and we further investigate their physical characteristics with the new long-slit spectroscopy observations and the archival multi-wavelength data. Based on energy balance calculations and assumptions about their possible nature, we propose that one of the shells is a possible remnant of a supernova explosion. We study five out of eight Wolf-Rayet (WR) star candidates previously published for this galaxy using the He ii emission line mapping, MUSE/VLT archival spectra, and new long-slit spectra. Our analysis discards the considered WR candidates and finds no new ones. We found P Cyg profiles in H{\alpha} line in two stars, which we classify as Luminous Blue Variable (LBV) star candidates. Overall, the galaxy IC 1613 may have a lower rate of WR star formation than previously suggested.

The analysis is based on the new observations performed in Ha emission line with high resolution ($R \sim 16000$) scanning Fabry-Perot interferometer at the 6-m BTA SAO RAS telescope, and on the long-slit spectral observations at the 9.2-m SALT and 2.5-m CMO SAI MSU telescopes. Strong non-circular gas motions detected in the studied regions probably resulted from the off-plane gas motions and impact of stellar feedback. We identified six regions of elevated Ha velocity dispersion, five of which exhibit asymmetric or two-component Ha line profiles. Three of these regions are young ($<1.1$ Myr) expanding ($V_{\rm exp} \sim 25-50\ {\rm km\ s^{-1}}$) superbubbles. We argue that at least three regions in the galaxy could be supernova remnants. We conclude that supernovae feedback is the dominant source of energy for superbubbles in Sextans B, which is expected for such a low metallicity, although we cannot rule out a strong impact of pre-supernova feedback for one superbubble., Comment: 16 pages, 6+6 figures, 4 tables. submitted to MNRAS after revision

Subjects: aneurysm, infrarenal aortic segment, reconstruction of artery, inferior mesenteric artery, internal iliac artery, long-term results, Surgery, RD1-811
Abstract: The OBJECTIVE is to assess the patency of the inferior mesenteric artery and internal iliac arteries in the remote period after resection of the aneurysm of the infrarenal aortic segment. MATERIAL AND METHODS. The study included 33 patients who underwent resection of the abdominal aortic aneurysm with reconstruction of the inferior mesenteric artery and (or) internal iliac arteries from 1998 to 2017. All patients were examined with computed tomography scan with contrast to assess the patency of inferior mesenteric artery and internal iliac arteries. RESULTS. Patients were observed from 0.5 to 15 years. Among 30 patients with inferior mesenteric artery implanted into the prosthesis, 23 (76 %) patients had a passable inferior mesenteric artery and 7 patients had an occluded inferior mesenteric artery. The implanted inferior mesenteric artery maintained its patency for 3 years in 100% of cases, from 3 to 5 years – in 86%, after 5 years and more – in 62%. In one patient who underwent reconstruction of the internal iliac artery, thrombosis of the prosthetic-internal iliac shunt was found out in 1.5 years after the operation, without any clinical manifestations. One patient, underwent the reconstruction of the internal iliac artery, was diagnosed with thrombosis of the prosthetic-internal iliac shunt in 1.5 years after the operation, which was not accompanied by clinical manifestations. CONCLUSION. The high remote patency of the inferior mesenteric artery and internal iliac arteries reconstructed during resection of the aneurysm of the infrarenal aortic segment indicates the need for this procedure in order to prevent ischemic disorders of the digestive organs and pelvis.

Abstract: OBJECTIVE. The purpose of this study was to evaluate the methods for preservation the patency of the internal iliac arteries during infrarenal aortic aneurysm resection.MATERIAL AND METHODS. The retrospective review was conducted in 200 patients who had undergone infrarenal aortic aneurysms resection between 1998 and 2017. The group 1 consisted of 8 patients who underwent the antegrade internal iliac arteries flow restoration by bypass or prosthetics. The group 2 consisted of 25 people who did not undergo restorating the patency of these arteries. The results were compared in both groups during the intraand early postoperative period.RESULTS. During the statistical analysis, there were no significant differences in duration of operation postoperative period, blood loss between two groups. Among the patients of the group 2, a transient ischemic colitis developed in one case, a prosthesis thrombosis developed in 5 patients. The complications described above have never been noted in the group 1.CONCLUSION. Direct revascularization of the internal iliac arteries during infrarenal aortic aneurism resection is an important factor of preventing the ischemic disorders of the pelvic organs and the left half of the colon do not significantly affect the volume of blood loss and the duration of the operation and the postoperative period.

Subjects: aneurism, infrarenal aorta, cholesterol crystal embolism, acute mesenteric ischemia, Surgery, RD1-811
Abstract: OBJECTIVE. According to the analytical data, the acute non-occlusive mesenteric ischemia after infrarenal aortic aneurism repair occurs in 0.2–1 % of cases. This complication is difficult to diagnose and associated with unfavorable prognosis and high mortality. MATERIAL AND METHODS. The retrospective analysis included 112 case histories of patients with infrarenal aortic aneurism repair in the period from 2007 to 2017. RESULTS. During the early postoperative period, 2 patients (1.8 %) had an acute non-occlusive mesenteric ischemia with lethal outcome. In these cases, the complication developed with safety patency of main mesenteric arteries and was followed by developing early multiorgan failure and thrombocytopenia. The autopsy showed generalized atherosclerosis, infarctions of kidneys, spleen and liver, caused by cholesterol crystal embolism of microvascular bed, which was found after histological research. CONCLUSION. The clinical presentation of acute non-occlusive mesenteric ischemia after infrarenal aortic aneurism repair is low-specific. One of the etiological factors of this complication is cholesterol crystal embolism in microvascular bed of visceral arteries

Abstract: A retrospective analysis of data of 188 patients, who underwent a selective surgery for abdominal aortic aneurism showed, that all the patients had a cardiac pathology. Ischemic heart disease and arterial hypertension had 175 (93,0%) and 177 (94,1%) of patients, respectively. Chronic nonspecific lung disease was noted in 65,4% patients and kidney disease — in 48,9%. Different complications developed in early postoperative period in 47 (25%) patients, that resulted in fatal outcome in 20 (10,6%). The most frequent complication was an acute renal insufficiency, which led to fatal outcome in 40% patients. Myocardial infarction and pneumonia took the second place in the structure of postoperative complications, one half of the fatal cases was due to these. Retrospective risk stratification assessment of the development of early postoperative complications and lethality was made by Glasgow Aneurysm Score (GAS) and angiosurgical model scale V-POSSUM. It was stated, that score was up to 84 according to GAS scale and up to 28 (V-POSSUM ). That fact is the evidence of high risk of the operation. On the basis of ROC curves building, the conclusion was made about greater predictive ability of V-POSSUM scoring system.

Abstract: A retrospective analysis of the data of 188 patients with the infrarenal segment of the aortic aneurysm (ISAA) showed, that ischemic heart disease and arterial hypertension were diagnosed practically in all patients — 175 (93.0%) and 177 (94.1%) patients respectively. A decreased retractor function of the myocardium was noted in 88 (46.8%) of patients. According to the findings of echocardiography 134 (71.3%) patients had the arterial hypertension of third degree. For the assessment of the influence of the accompanying cardiac pathology on the results of planned surgical treatment and systematization of postoperative cardiac complications the classification, which was proposed by R. B. Rutherford et al. and modified by A. V. Pokrovsky et al. was used. The obtained data point at a direct proportional relationship between the degree of the initial cardiac status, frequency and severity of postoperative cardiac complications in patients after resection of ISAA in 1.6–2.3 times.

Abstract: Retrospective analysis of data in 188 patients showed, that chronic nonspecific pulmonary disease was diagnosed in 65,4 % of all. Disorders of bronchial patency of different degrees of manifestation were noted in 61,2 % and 19,7 % of patients had a hypoxemia. Renal diseases were found in 59 % of patients, resulting in the development of chronic renal insufficiency in 17 %. The data obtained indicate, that the presence of coexisting pulmonary pathology directly influences the frequency and severity of respiratory complications after surgery, which can be the cause of fatal outcome. The presence of renal diseases results in three times higher risk of the development of postoperative renal complications.

Abstract: The similarity in physical conditions in winds of low-mass post-asymptotic giant branch stars and evolved massive stars leads to the appearance of an interesting phenomenon of spectral mimicry. Due to that the discovery of every new star with Wolf--Rayet spectrum requires special study of its evolutionary status before it may be included in the list of Galactic Wolf--Rayet (WR) stars. A couple of years ago LAMOST J040901.83+323955.6 (hereafter J0409+3239) was selected as a WR star in LAMOST spectroscopic database by machine learning methods. In this work we investigated its evolutionary status. Analyzing the spatial location of J0409+3239, in the Galaxy and its position in the color-magnitude diagram we concluded what J0409+3239, is instead a low mass object with WR phenomenon. Its luminosity is $L*=1000 L_\odot$ and effective temperature $T_{\rm eff}$=40,000 K. Using new and archival photometric data we detected irregular variability on time scales from hours to tens of days with amplitude up to $\approx0.2$ mag. Comparison of the spectrum obtained in 2022 with the one from 2014 also shows an evidence of spectral variability. The absence of clearly detected circumstellar nebula does not allow to classify J0409+3239, as [WR], i.e. a central star of planetary nebula (CSPN). However, its position in Hertzsprung--Russell diagram suggests that J0409+3239, is a low mass star caught in rare transitional phase to CSPN. Estimation of J0409+3239, mass based on evolutionary tracks shows that it is less than $0.9~M_\odot$, and thus the age of the Galaxy is barely enough for the star to evolve to its current stage., Comment: 10 pages, 5 figures, 3 tables, accepted for publication in MNRAS

Abstract: This report introduces a new family of multimodal models, Gemini, that exhibit remarkable capabilities across image, audio, video, and text understanding. The Gemini family consists of Ultra, Pro, and Nano sizes, suitable for applications ranging from complex reasoning tasks to on-device memory-constrained use-cases. Evaluation on a broad range of benchmarks shows that our most-capable Gemini Ultra model advances the state of the art in 30 of 32 of these benchmarks - notably being the first model to achieve human-expert performance on the well-studied exam benchmark MMLU, and improving the state of the art in every one of the 20 multimodal benchmarks we examined. We believe that the new capabilities of the Gemini family in cross-modal reasoning and language understanding will enable a wide variety of use cases. We discuss our approach toward post-training and deploying Gemini models responsibly to users through services including Gemini, Gemini Advanced, Google AI Studio, and Cloud Vertex AI.

Abstract: Detailed measurements of the spectral structure of cosmic-ray electrons and positrons from 10.6 GeV to 7.5 TeV are presented from over 7 years of observations with the CALorimetric Electron Telescope (CALET) on the International Space Station. Because of the excellent energy resolution (a few percent above 10 GeV) and the outstanding e/p separation (10$^5$), CALET provides optimal performance for a detailed search of structures in the energy spectrum. The analysis uses data up to the end of 2022, and the statistics of observed electron candidates has increased more than 3 times since the last publication in 2018. By adopting an updated boosted decision tree analysis, a sufficient proton rejection power up to 7.5 TeV is achieved, with a residual proton contamination less than 10%. The observed energy spectrum becomes gradually harder in the lower energy region from around 30 GeV, consistently with AMS-02, but from 300 to 600 GeV it is considerably softer than the spectra measured by DAMPE and Fermi-LAT. At high energies, the spectrum presents a sharp break around 1 TeV, with a spectral index change from -3.15 to -3.91, and a broken power law fitting the data in the energy range from 30 GeV to 4.8 TeV better than a single power law with 6.9 sigma significance, which is compatible with the DAMPE results. The break is consistent with the expected effects of radiation loss during the propagation from distant sources (except the highest energy bin). We have fitted the spectrum with a model consistent with the positron flux measured by AMS-02 below 1 TeV and interpreted the electron + positron spectrum with possible contributions from pulsars and nearby sources. Above 4.8 TeV, a possible contribution from known nearby supernova remnants, including Vela, is addressed by an event-by-event analysis providing a higher proton-rejection power than a purely statistical analysis., Comment: main text: 7 pages, 4 figures; supplemental material: 10 pages, 8 figures, 1 table

38. Single-photon scattering on a two-qubit system. Spatio-temporal structure of the scattered field

Author: Greenberg, Ya. S., Shtygashev, A. A., and Moiseev, A. G.
Subjects: Quantum Physics, Condensed Matter - Mesoscale and Nanoscale Physics
Abstract: In this paper, we study the spatiotemporal distribution of the photon electric field produced by the scattering of a single photon narrow pulse from a system of two identical qubits coupled to continuum modes in a one-dimensional (1D) open waveguide. We derive the time-dependent dynamical equations for qubits' and photon amplitudes which allow the calculation of the photon backward and forward scattering fields in the whole space: before qubits, between qubits, and behind the qubits. The scattered field consists of several contributions that describe a free field of incoming photon, a spontaneous exponential decay of excited qubits, a slowly decaying part that dies out as the inverse powers of $t$, and a lossless part that represents a steady state solution as $t\rightarrow\infty$. For our system, we find the transmittance and reflectance fields as both time and distance from the qubits tend to infinity. We show that as the time after the event of scattering tends to infinity, the steady state photon the field is being formed in the whole one-dimensional space. If the distance $d$ between qubits is equal to the integer of the wavelength $\lambda$, the field energy exhibits temporal beatings between the qubit frequency $\Omega$ and the photon frequency $\omega_S$ with the period $T=2\pi/(\omega_S-\Omega)$., Comment: 19 pages, 11 Figures, 39 References

39. 3D structure of HII regions in the star-forming complex S254-S258

Author: Kirsanova, Maria S., Moiseev, Alexei V., and Boley, Paul A.
Subjects: Astrophysics - Astrophysics of Galaxies
Abstract: The S254-258 star-forming complex is a place of massive star formation where five OB-stars have created HII regions, visible as optical nebulae, and disrupted the parental molecular gas. In this work, we study the 3D structure of these \HII regions using optical spectroscopy and tunable-filter photometry with the 6-m and 1-m telescopes of the Special Astrophysical Observatory of the Russian Academy of Sciences. We construct maps of the optical extinction, and find that the HII emission is attenuated by neutral material with $2 \leq A_V \leq 5$ mag. The typical electron density in S255, and S257 is $\approx 100$ cm$^{-3}$, with enhancements up to 200 cm$^{-3}$ in their borders, and up to 400 cm$^{-3}$ toward the dense molecular cloud between them, where active star formation is taking place. We show that either a model of a clumpy dense neutral shell, where UV~photons penetrate through and ionize the gas, or a stellar wind, can explain the shell-like structure of the ionized gas. S255 is surrounded by neutral material from all sides, but S257 is situated on the border of a molecular cloud and does not have dense front and rear walls. The compact HII regions S256 and S258 are deeply embedded in the molecular clouds., Comment: accepted by MNRAS

Abstract: The article presents the scale developed by authors of prognostic assessment of ischemic colitis evolution in patients after planned resection of infrarenal aortic aneurism. A retrospective analysis of medical histories of 201 operated patients and statistical data manipulation were made at the period from 1985 to 2016. It was stated, that score less than 2 points represents patients of high risk group of ischemic colitis development. The scale of sensitivity consisted of 80% and scale of specificity - 63,4%. The score of developed scale depended of passability and blood flow condition in the inferior mesenteric, the right and left internal iliac arteries being evaluated during surgery. The aim of surgeons is to increase the number of points in the scale using revascularization of the inferior mesenteric and at least one of internal iliac artery in patients of the high risk group of ischemic colitis development.

41. BYPASS SURGERY IN PATIENTS WITH COMBINED ATHEROSCLEROTIC LESIONS OF COMMON AND INTERNAL CAROTID ARTERY

Author: N. A. Yaitskiy, A. Ya. Bedrov, D. V. Maslevtsov, A. A. Vrabiy, A. A. Moiseev, and Yu. A. Pugachenko
Subjects: atherosclerosis, chronic cerebrovascular disease, common carotid artery, bypass surgery, Surgery, RD1-811
Abstract: An analysis of data of carotid angiographies was made in 146 patients with chronic cerebrovascular disease. Combined lesions of the common and internal carotid artery with clinical signs were revealed in 2 (1,4%) patients. A crossed extraanatomic bypass from the left common carotid artery to the right internal carotid artery was performed in one patient. The orthotopic common-internal autovenous bypass on the right side was carried out for another patient. According to obtained results, the authors suggested that the orthotopic or extraanatomic common-internal carotid artery bypasses could be applied in case of impossibility of endovascular intervention, when patients had the combined atherosclerotic lesions of common carotid and internal carotid artery.

46. Gas Kinematics in the Magellanic-Type Galaxy NGC 7292

Author: Gusev, A. S., Moiseev, A. V., and Zheltoukhov, S. G.
Subjects: Astrophysics - Astrophysics of Galaxies
Abstract: The paper presents results of studying the kinematics of the ionized gas in the galaxy of the Large Magellanic Cloud type NGC 7292 obtained with the 2.5-m telescope of the Caucasian Mountain Observatory (CMO SAI MSU) and the 6-m BTA telescope of the Special Astrophysical Observatory (SAO RAS). Analysis of the velocity fields of the ionized and neutral hydrogen showed that the kinematic center of NGC 7292 located at the center of the bar, northwest of the photometric center of the galaxy (the southeastern end of the bar) previously taken as the center of NGC 7292. In addition to the circular rotation of the gas, the radial motions associated with the bar play a significant role in the kinematics of the disk. The observed perturbations of the gaseous-disk kinematics induced by the ongoing star formation do not exceed those caused by the bar. It is possible that part of the non-circular motions (at the southeastern end of the bar which is the brightest HII region) may be related to the effects of the capture of a dwarf companion or a gaseous cloud., Comment: Slightly edited version of the paper published in the Astrophysical Bulletin. 10 pages, 8 figures, 1 table

Abstract: The Compton Pair (ComPair) telescope is a prototype that aims to develop the necessary technologies for future medium energy gamma-ray missions and to design, build, and test the prototype in a gamma-ray beam and balloon flight. The ComPair team has built an instrument that consists of 4 detector subsystems: a double-sided silicon strip detector Tracker, a novel high-resolution virtual Frisch-grid cadmium zinc telluride Calorimeter, and a high-energy hodoscopic cesium iodide Calorimeter, all of which are surrounded by a plastic scintillator anti-coincidence detector. These subsystems together detect and characterize photons via Compton scattering and pair production, enable a veto of cosmic rays, and are a proof-of-concept for a space telescope with the same architecture. A future medium-energy gamma-ray mission enabled through ComPair will address many questions posed in the Astro2020 Decadal survey in both the New Messengers and New Physics and the Cosmic Ecosystems themes. In this contribution, we will give an overview of the ComPair project and steps forward to the balloon flight., Comment: Proceedings for the 38th International Cosmic Ray Conference (ICRC2023)

48. Dynamical theory of single-photon transport through a qubit chain coupled to a one-dimensional nanophotonic waveguide

Abstract: We study the dynamics of a single-photon pulse travelling through a linear qubit chain coupled to continuum modes in a one-dimensional (1D) photonic waveguide. We derive a time-dependent dynamical theory for qubit amplitudes and for transmitted and reflected spectra. We show that the requirement for the photon-qubit coupling to exist only for positive frequencies can significantly change the dynamics of the system. First, it leads to an additional photon-mediated dipole-dipole interaction between qubits which results in the violation of the phase coherence between them. Second, the spectral lines of transmitted and reflected spectra crucially depend on the shape of the incident pulse and the initial distance between the pulse center and the first qubit in the chain. We apply our theory to one-qubit and two-qubit systems. For these two cases, we obtain the explicit expressions for the qubits' amplitudes and the photon radiation spectra as time tends to infinity. For the incident Gaussian wave packet we calculate the line shapes of transmitted and reflected photons., Comment: 16 pages, 12 figures, 54 references. This version is the deeply revized version of the previous paper Dynamical theory of single-photon transport through a qubit chain coupled to a one-dimensional nanophotonic waveguide.

Abstract: We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected rotation ephemerides are achieved. A further dozen optical and/or X-ray binary systems co-located with LAT sources also likely harbor gamma-ray MSPs. This catalog thus reports roughly 340 gamma-ray pulsars and candidates, 10% of all known pulsars, compared to $\leq 11$ known before Fermi. Half of the gamma-ray pulsars are young. Of these, the half that are undetected in radio have a broader Galactic latitude distribution than the young radio-loud pulsars. The others are MSPs, with 6 undetected in radio. Overall, >235 are bright enough above 50 MeV to fit the pulse profile, the energy spectrum, or both. For the common two-peaked profiles, the gamma-ray peak closest to the magnetic pole crossing generally has a softer spectrum. The spectral energy distributions tend to narrow as the spindown power $\dot E$ decreases to its observed minimum near $10^{33}$ erg s$^{-1}$, approaching the shape for synchrotron radiation from monoenergetic electrons. We calculate gamma-ray luminosities when distances are available. Our all-sky gamma-ray sensitivity map is useful for population syntheses. The electronic catalog version provides gamma-ray pulsar ephemerides, properties and fit results to guide and be compared with modeling results., Comment: 142 pages.

Abstract: Herein, we describe the design, implementation and operation principles of an astronomical camera system, based on a large-format CCD261-84 detector with an extremely thick 200 mkm substrate. The DINACON-V controller was used with the CCD to achieve high performance and low noise. The CCD system photometric characteristics are presented. A spatial autocorrelation analysis of flat-field images was performed to reveal the dependence of substrate voltage on the lateral charge spreading. The investigation of the dispersion index for the optimal choice of exposure time is discussed. Studies of the patterns of fringes were carried out in comparison with previous detectors. The amplitude of fringes with CCD261-84 was significantly lower, compared to previous-generation detectors. The results of using a new camera for imaging and spectral observations at the Russian 6 m telescope with the SCORPIO-2 multimode focal reducer are considered. The developed CCD camera system makes it possible to significantly increase the sensitivity in the 800-1000 spectral range., Comment: 15 pages, 10 figures, 1 table
