Authors: Zhuikov B L , Ermolaev S V 
Published: July 2021

Abstract
Radioisotope research at the linear accelerator of INR RAS has been developing since 1989. In 1992, a facility for the irradiation of isotope targets and radioisotope production was built, operating on a diverted proton beam with an energy of 160 MeV and a current of more than 120 μA, which was the most productive facility in the world at that time. The facility is used for both fundamental and applied research. The main focus is the study of the processes of the generation and recovery of medical radioisotopes, as well as the development of technology for their production. The main radionuclides produced now are strontium-82 and actinium-225. A Russian 82 Sr/82 Rb generator for PET-diagnostics has been developed by INR RAS and is being introduced for medicine. New types of 225Ac/213Bi generators are also being developed for the treatment of oncological diseases. In addition, the study of the process for the production and chemical recovery of medical radionuclides 117mSn, 68 Ge, 72Se, 64, 67Cu, 223Ra, 230 Pa, and 230U is being carried out, as is the study of some generators with some of these isotopes. The technology developed at INR is used in Russia and abroad. Physical processes of proton interaction with different nuclei are also investigated in the laboratory of the radioisotope complex of INR RAS. The produced 22Na, 83Rb, 109Cd, and radioactive sources with these radionuclides are used in physical research and technology.

An Efficient Algorithm for Retrieving CO2 in the Atmosphere From Hyperspectral Measurements of Satellites: Application of NLS-4DVar Data Assimilation Method
Authors: Jin Zhe , Tian Xiangjun , Duan Minzheng , Han Rui 
Published: July 2021

A novel and efficient inverse method, named Nonlinear least squares four-dimensional variational data Assimilation (NLS-4DVar)-based CO2 Retrieval Algorithm (NARA), is proposed for retrieving atmospheric CO2 from the satellite hyperspectral measurements, in which the NLS-4DVar method is used as the optimization method. As the NLS-4DVar method works independently of the tangent linear model and adjoint model, the time-consuming calculation of the weighting function matrix is unnecessary, and the computation complexity is tremendously reduced while maintaining the retrieval accuracy. This is extremely important for space-based CO2 retrievals with large data volumes. Observing system simulation experiments (OSSEs) over four different sites around the world showed that the NARA algorithm could retrieve XCO2 and CO2 profiles effectively. To further evaluate the NARA algorithm, it was used for real CO2 retrievals from target-mode observations of Orbiting Carbon Observatory-2 (OCO-2) over Lamont, Oklahoma, and Darwin, Australia. The results were compared with that of ground measurements of Total Carbon Column Observing Network (TCCON). The mean difference of XCO2 between NARA and TCCON over Lamont, from 180 observations, was −0.15 ppmv with a standard deviation (SD) of 0.76 ppmv. Over Darwin, the mean difference, from 180 observations (90 points over land and 90 points over the ocean), is −0.17 ppmv (SD: 1.26 ppmv). The preliminary results showed that the efficient NLS-4DVar-based algorithm could provide great help for satellite remote sensing of CO2, and it may be used as an operational procedure after further and extensive evaluations.

Published: July 2021

BackgroundUnderstanding intra-fractional prostate motions is crucial for stereotactic body radiation therapy (SBRT). No studies have focused on the intra-fractional prostate motions during re-irradiation with SBRT. The objective was to evaluate these translational and rotational motions in primary treated patients and in the context of re-irradiation.MethodsFrom January 2011 to March 2020, 162 patients with histologically proven prostate cancer underwent prostate SBRT, including 58 as part of a re-irradiation treatment. We used the continuous coordinates of the fiducial markers collected by an orthogonal X-ray dual-image monitoring system. The translations and rotations of the prostate were calculated. Prostate deviations representing overall movement was defined as the length of the 3D-vectors.ResultsA total of 858 data files were analyzed. The deviations over time in the group of primary treated patients were significantly larger than that of the group of re-irradiation, leading to a mean deviation of 2.73 mm (SD =1.00) versus 1.90 mm (SD =0.79), P&lt;0.001. In the re-irradiation group, we identified displacements of -0.05 mm (SD =1.53), 0.20 mm (SD =1.46); and 0.42 mm (SD =1.24) in the left-right, superior-inferior and anterior-posterior planes. Overall, we observed increasing deviations over the first 30 min followed by a stabilization related to movements in the three translational axes.ConclusionThis is the first study to focus on intrafraction prostate motions in the context of re-irradiation. We observed that intra-fraction prostate motions persisted in the setting of re-irradiation, although they showed a significant reduction when compared with the first irradiation. These results will help to better estimate random errors during SBRT treatment of intra-prostatic recurrence after irradiation.

Objective: To determine the prevalence and associated demographic and clinical features of borderline intellectual functioning (BIF) among individuals with polysubstance use disorder (pSUD).Methods: We applied a cross-sectional analytical design to data from the Norwegian STAYER study (n = 162), a cohort study of patients with a pSUD from the Stavanger University hospital catchment area. We used Wechsler Abbreviated Scale of Intelligence Full Scale IQ (FSIQ) to define BIF (FSIQ = 70–85) and non-BIF (FSIQ = &gt;85) and collected demographic and clinical data using semi-structured interviews and self-reports on the Symptom Checklist 90-Revised (SCL-90-R) and the Satisfaction With Life Scale (SWLS).Results: The prevalence of BIF was 18% in the present study. The presence of BIF was associated with higher SCL-90-R GSI scores than in the non-BIF group. There were no significant differences between the BIF and non-BIF groups regarding age, gender, participation in meaningful daily activity, years of work experience, years of education, satisfaction with life, level of care, treatment attempts, age at substance-use onset, years of substance use, history of injecting drugs, or age of onset of injecting drugs.Conclusion: The present study confirmed a higher prevalence of BIF among patients with pSUD than expected from the distribution of IQ scores in a general population. Elevated SCL-90-R GSI scores suggested that BIF is associated with increased psychological distress in patients receiving treatment for pSUD. Further studies on this association, and its effect on treatment procedure and outcomes are strongly warranted.

Data diperoleh melalui pelibatan beragam sumber informasi, yakni wawancara, pengamatan, bahan audiovisual, dokumen dan berbagai laporan yang terkait dengan fenomena hijrah dan politik di kalangan perempuan muslim kelas menegah Kota Semarang. Penelitian ini menunjukan, dalam Pilpres tahun 2019 mayoritas kelompok hijrah perempuan di Kota Semarang memberikan suaranya kepada pasangan calon Prabowo Subianto-Sandiaga Uno. Dalam momentum Itjima Ulama yang digelar dua kali, para ulama merekomendasikan pasangan ini secara resmi melalui pakta integritas. Selain itu, pasangan ini dianggap merepresentasikan umat karena partai pengusung keduanya yang memiliki kedekatan dan keberpihakan pada kaum ulama. Pada akhirnya, fenomena trend hijrah menunjukan dua hal. Pertama, pengaruh tokoh publik dan gencarnya gerakan hijrah semakin memperkuat identitas mereka sebagai sebuah kelompok. Kedua, secara lebih lanjut kelompok ini memberikan bukti bahwa hijrah tidak hanya perubahan dalam kehidupan beragama dan bersosial tetapi juga memberi sebuah aksi nyata dalam kontestasi politik skala nasional.Kata Kunci: Hijrah, Kelompok hijrah, Perempuan, dan Pilihan Politik
L'orgue à bouche lao (khène) : Production et échange d'un bien culturel

The Lao Mouth Organ (khaen) : Production and Trading of a Cultural Artifact.
Julien Rousseau.

This article is an ethnographic study of the making of Lao mouth organs (khaen) through its ritual, economic and technical aspects. Specific technical skills and religious practice allow mouth organ makers to produce music instruments that are considered authentic and meaningful from a social point of view. Mouth organ making cannot be reduced to a mere cultural phenomenon, because the craftsmen who produce these instruments are fully part of the economy of a society that is quickly changing from socialism to capitalism. Nevertheless, we will try to emphasize that, despite attempts at introducing some economic rationale to its production, the Lao mouth organ remains more an identity artifact than a commodity.

Geographies of Intertextuality : Buddhist Literature in Pre-modern Siam.
Peter Skilling.

Far from being marginal or provincial, Southeast Asia— this land "between India and China"— was a cultural crossroads, with intricate links by land and sea with the wider world. In the geographic imagination, Southeast Asia was located in Jambudvīpa, the "Southern Continent" of Buddhist cosmology. The article examines the Buddhist literature of the region, in particular the Pāli and vernacular literature of Siam. It hopes to show that Siam was part of a wider textual and cultural community, which was in constant dialogue with the Indian Ocean region and beyond. It proposes that vibrant cultural exchange was the norm rather than the exception, and that this exchange contributed to the exuberant creativity of Siamese and Tai literature. It suggests that we should look more closely at literary production in order to understand the intellectual and social history of Siam in broader transregional contexts.
Traditional Shadow Theater of Northeastern Thailand (Nang Pramo Thai). Hardy Transplant or Endangered Species ?

Traditional Shadow Theatre of Northeastern Thailand
(Nang Pramo Thai).
Hardy Transplant or Endangered Species ?
Bonnie Brereton and Somroay Yencheuy.

Shadow theatre is a relatively new phenomenon in northeastern Thailand (where it is known as nang pramo thai)— probably dating from no earlier than the first quarter of the twentieth century. This article explores the status of this dramatic form in the central provinces of the region and contrasts it with that of the traditional shadow theatre of southern Thailand. Unlike its southern counterpart, nang pramo thai is a little-known and relatively minor form of entertainment, found mainly in villages, with a limited repertoire confined mostly to scenes from the Ramakian and the Sin Sai story.
Yet, despite its low profile, nang pramo thai in many ways embodies the essence of the local culture of the Northeast. This can be seen not only in its robust music, high-spirited puppetry and inclusion of women puppeteers ; but also in the performers' ingenuity in adopting an "imported tradition" and transforming it into a local one when faced with financial hardship.
From Champasak to Cambodia: Ya Chao Tham (Chao Thammatheva), a Wily and Influential Ethnic Lao Leader
Authors: Baird Ian G. 
Published: July 2021

Ya Chao Tham, or Chao Thammatheva, was the son of the ninth king of Champasak, Chao Boua, and the grandson of the fourth king of Champasak, Chao Nou. He played an important role in shaping the political circumstances in the Laos-Cambodia border region for almost half a century, from the 1880s until his death in the early 1930s. Born to the Champasak royal family in present-day southern Laos, he travelled to the Sesan River Basin in present-day northeastern Cambodia in the 1880s, where he allegedly used his magical powers to suppress the highlanders who lived there and to establish Veun Say on behalf of Champasak and their Siamese mentors. Later, after the French gained control of the east bank of the Mekong River in 1893, Ya Chao Tham continued to wield considerable power within the French Lao administration. In late 1904 Stung Treng— including Veun Say— became a province of the French protectorate of Cambodia. Ya Chao Tham adapted to the circumstances, becoming the first governor of Stung Treng. He fell in and out of favour with the French from then onwards, but retained considerable influence in the region right up until the time of his death. This article traces Ya Chao Tham’s personal history in the context of the broader political and sociocultural circumstances of which he was a part, especially of the establishment of the ethnic Lao population along the Sesan River. The account relies
on both archival and oral sources. I examine how this wily and influential ethnic Lao leader became entwined in the sociopolitical life of the region, while explaining the overriding recent history of the Sayakouman line of the royal family of Champasak, of which Ya Chao Tham was a key member.

Разработана структура системы V2X(Vehicle-to-Everything), позволяющей на базе сети 5G организовать взаимодействие между объектами дорожной инфраструктуры, беспилотными и высокоавтоматизированными транспортными средствами, пешеходами и другими сетями. Для производительной работы в условиях плотного трафика транспортных средств в системе V2X использованы технология мобильных граничных вычислений MEC (Mobile Edge Computing) и алгоритм выгрузки трафика, позволяющий управлять нагрузкой данных на граничные и облачные серверы. Результаты моделирования для различных сценариев показали, что предложенные структура и алгоритм выгрузки могут значительно снизить задержки в передаче данных и энергопотребление системы.
The V2X (Vehicle-to-Everything) system structure has been developed, which allows, based on 5G network, to organize interaction between road infrastructure objects, unmanned and highly automated vehicles, pedestrians, and other networks. For efficient operation in conditions of dense vehicle traffic, the V2X system uses the mobile edge computing technology and a traffic offloading algorithm, which allows managing the data load on the edge cloud servers. Simulation results for various scenarios showed that the proposed structure and offloading algorithm can significantly reduce data transfer delays and system power consumption.

Published: July 2021

Внедрение стандартов цифровой радиосвязи в гражданской авиации происходит практически без взаимодействия с международными организациями по стандартизации в области телекоммуникаций. При этом цифровая связь используется в первую очередь для обеспечения безопасности полетов воздушных судов. По радиоканалу в вещательном режиме каждое воздушное судно передает информацию о своем местоположении, обеспечивая таким образом ситуационную осведомленность экипажей других судов и диспетчеров. Поскольку число пассажирских и грузовых судов растет, а кроме того, в последнее время многократно возросло число беспилотных судов,которые должны быть интегрированы в общее воздушное пространство, то назрела необходимость рассмотреть существующие стандарты цифровой авиационной связи и провести сравнительный анализ их параметров. В данной работе выполнен сравнительный анализ физического и канального уровней стандартов VDL mode 4 и 090ES,а также представлены критерии качества передачи данных с помощью технологии автоматического зависимого наблюдения-вещания. Сравнение проведено по результатам моделирования работы стандартов в условиях высокой загруженности воздушного пространства.
Digital communication standards implementation in civil aviation is now performed practically without collaboration with international telecommunications standardization organizations. At the same time, digital communication is primarily intended to ensure the safety of aircraft flights. Each aircraft transmits its position report messages over a radio communication channel in a broadcast mode, thus providing situational awareness for other aircrafts and the air traffic control staff. Since the number of passenger and cargo aircrafts grows, and in addition, the number of unmanned aircraft that must be integrated into the common airspace has recently multiplied, it is time to consider the existing digital aviation communication standards and perform a comparative analysis of their parameters. In the article, a comparative analysis of the physical and link levels of the VDL mode 4 and 1090ES standards was carried out. The ADS-B data transfer quality evaluation criteria are proposed. The VDL mode 4 and 1090ES standards modeling results in conditions of high airspace congestion are compared.
