Spectral Inversion of Multi-Line Full-Disk Observations of Quiet Sun Magnetic Fields

Spectral inversion codes are powerful tools to analyze spectropolarimetric observations, and they provide important diagnostics of solar magnetic fields. Inversion codes differ by numerical procedures, approximations of the atmospheric model, and description of radiative transfer. Stokes Inversion based on Response functions (SIR) is an implementation widely used by the solar physics community. It allows to work with different atmospheric components, where gradients of different physical parameters are possible, e.g., magnetic field strength and velocities. The spectropolarimetric full-disk observations were carried out with the Stokesmeter of the Solar Telescope for Operative Predictions (STOP) at the Sayan Observatory on 3 February 2009, when neither an active region nor any other extended flux concentration was present on the Sun. In this study of quiet Sun magnetic fields, we apply the SIR code simultaneously to 15 spectral lines. A tendency is found that weaker magnetic field strengths occur closer to the limb. We explain this finding by the fact that close to the limb, we are more sensitive to higher altitudes in an expanding flux tube, where the field strength should be smaller since the magnetic flux is conserved with height. Typically, the inversions deliver two populations of magnetic elements: (1) high magnetic field strengths (1500-2000 G) and high temperatures (5500-6500 K) and (2) weak magnetic fields (50-150 G) and low temperatures (5000-5300 K).Comment: 10 pages, 6 figures, accepted for Solar Physic

Evolution of active and polar photospheric magnetic fields during the rise of Cycle 24 compared to previous cycles

The evolution of the photospheric magnetic field during the declining phase and minimum of Cycle 23 and the recent rise of Cycle 24 are compared with the behavior during previous cycles. We used longitudinal full-disk magnetograms from the NSO's three magnetographs at Kitt Peak, the Synoptic Optical Long-term Investigations of the Sun (SOLIS) Vector Spectro-Magnetograph (VSM), the Spectromagnetograph and the 512-Channel Magnetograph instruments, and longitudinal full-disk magnetograms from the Mt. Wilson 150-foot tower. We analyzed 37 years of observations from these two observatories that have been observing daily, weather permitting, since 1974, offering an opportunity to study the evolving relationship between the active region and polar fields in some detail over several solar cycles. It is found that the annual averages of a proxy for the active region poloidal magnetic field strength, the magnetic field strength of the high-latitude poleward streams, and the time derivative of the polar field strength are all well correlated in each hemisphere. These results are based on statistically significant cyclical patterns in the active region fields and are consistent with the Babcock-Leighton phenomenological model for the solar activity cycle. There was more hemispheric asymmetry in the activity level, as measured by total and maximum active region flux, during late Cycle 23 (after around 2004), when the southern hemisphere was more active, and Cycle 24 up to the present, when the northern hemisphere has been more active, than at any other time since 1974. The active region net proxy poloidal fields effectively disappeared in both hemispheres around 2004, and the polar fields did not become significantly stronger after this time. We see evidence that the process of Cycle 24 field reversal has begun at both poles.Comment: Accepted for publication in Solar Physic

Baikal-GVD

We present the status of the Gigaton Volume Detector in Lake Baikal (Baikal-GVD) designed for the detection of high energy neutrinos of astrophysical origin. The telescope consists of functionally independent clusters, sub-arrays of optical modules (OMs), which are connected to shore by individual electro-optical cables. During 2015 the GVD demonstration cluster, comprising 192 OMs, has been successfully operated in Lake Baikal. In 2016 this array was upgraded to baseline configuration of GVD cluster with 288 OMs arranged on eight vertical strings. Thus the instrumented water volume has been increased up to about 5.9 Mtons. The array was commissioned in early April 2016 and takes data since then. We describe the configuration and design of the 2016 array. Preliminary results obtained with data recorded in 2015 are also discussed

Эффективность уретральной эндосфинктеропластики у детей с недержанием мочи при миелодисплазии и эписпадии

BACKGROUND: Periurethral injections of various materials in the treatment of stress urinary incontinence have been known since 1938. In the literature, we could not find reports of endosurgical correction of urinary incontinence as the main method of treatment in children with myelodysplasia and epispadias and a pathogenetically based examination algorithm to predict the result of the injection, taking into account the endoscopic technique and volume of the injected drug. AIM: To present an assessment of long-term results, i.e., correction of stress urinary incontinence in children with myelodysplasia and epispadias, after endoimplantation of a stable synthetic volume-forming polymer. MATERIALS AND METHODS: The study analyzed 38 patients (517 years old) with urinary incontinence with myelodysplasia and epispadias: boys and girls with epispadias (n = 9 and n = 3, respectively) and with myelodysplasia (n = 10 and n = 16), respectively. For diagnostic purposes, clinical and instrumental (excretory urography, cystography, cystoscopy, uroflowmetry, electrophysiological, and urodynamic) examination methods were used. To correct incontinence, intra- and paraurethral endoinjections of a stable polyacrylamide mesh polymer with silver ions were performed. RESULTS: According to the literature, the effectiveness of the intraurethral administration of stable implants with urinary incontinence in catamnesis for up to 12 months reached 50%; with longer follow-up, positive results did not exceed 40% of observations. In this study, complete retention of urine was achieved in 25 (66%) children. Satisfactory result (incontinence in the afternoon up to 40 mL) was observed in 8 (21%) children, and unsatisfactory in 5 (13%) children. DISCUSSION: Indications for endosphincteroplasty in children with stress incontinence having myelodysplasia and epispadias with a stable implant should be determined considering urodynamics, blood circulation, innervation, and functional (urethral profilometry) parameters in the detrusor-sphincters-pelvic floor system. CONCLUSIONS: In patients with myelodysplasia and epispadias with isolated insufficiency of urethral sphincters, surgical treatments can be performed independently, and their effectiveness can reach 70%.Актуальность. Периуретральные инъекции различных материалов в лечении пациентов со стрессовым недержанием мочи известны с 1938 г. В литературных источниках нам не удалось встретить сообщений об эндохирургической коррекции недержания мочи при миелодисплазии и эписпадии у детей как основного метода лечения, патогенетически обоснованного алгоритма обследования для прогнозирования результата инъекции с учетом эндоскопической техники и объема введенного препарата. Цель оценить отдаленные результаты коррекции стрессового недержания мочи у детей с миелодисплазией и эписпадией после эндоимплантации стабильного синтетического объемообразующего полимера. Материалы и методы. Объектом исследования были 38 пациентов (517 лет) с недержанием мочи с миелодисплазией и эписпадией: мальчиков с эписпадией 9, девочек 3; с миелодисплазией мальчиков 10, девочек 16. С диагностической целью использовали клинические, инструментальные (экскреторную урографию, цистографию, цистоскопию, урофлоуметрию, электрофизиологические и уродинамические) методы обследования. Для коррекции инконтиненции выполняли внутри- и парауретральную эндоинъекцию стабильного полиакриламидного сетчатого полимера с ионами серебра. Результаты. По данным литературы, эффективность внутриуретрального введения стабильных имплантов при недержании мочи в катамнезе до 12 мес. достигала 50 %, при более длительном наблюдении положительные результаты не превышали 40 % наблюдений. В представленной работе полное удержание мочи достигнуто у 25 детей (66 %). Удовлетворительный результат (инконтиненция днем до 40 мл) зарегистрирован в 8 наблюдениях (21 %). Неудовлетворительный результат у 5 детей (13 %). Обсуждение. Показания к эндосфинктеропластике у детей со стрессовой инконтиненцией при миелодисплазии и эписпадии стабильным имплантом должны определяться с учетом уродинамики, кровообращения, иннервации и функциональных (уретральная профилометрия) параметров в системе детрузор сфинктеры тазовое дно. Заключение. Операции данного типа у пациентов с миелодисплазией и эписпадией с изолированной недостаточностью уретральных сфинктеров могут проводиться как самостоятельный метод, а их эффективность достигать 70 %

Ethnic Representations of Tuvans about Themselves and Others: The Factor of Location

The article presents the results of a study of the ideas of Tuvans about the individual psychological characteristics of representatives of the Tuvan and Russian ethnic groups. The subjects of the study were Tuvinians living in the largest city of the Republic of Tyva &mdash; Kyzyl (n=72) and in a remote, southwestern region of the Republic of Tyva &mdash; Mongun-Taiginsky district (n=69). As part of the study, the author's methodology "Cards" was used, which allows for the assessment and self-assessment of individual psychological characteristics in a concise and understandable format for respondents. The analysis of the data was carried out taking into account three age cohorts of the subjects &mdash; the younger, middle and older age groups. Differences were recorded in the content of the representations of Tuvans of different age groups in relation to representatives of the Russian and Tuvan ethnic groups. The age factor had a more significant impact to ethnic representations than the place of residence and life.</p
