description: We introduce a class of spin models with long-range interactions---in the sense that they extend significantly beyond nearest neighbors---whose ground states can be constructed analytically and have a simple matrix product state representation. This enables the detailed study of ground state properties, such as correlation functions and entanglement, in the thermodynamic limit. The spin models presented here are closely related to lattice gases of strongly interacting polar molecules or Rydberg atoms which feature an excluded volume or blockade interaction. While entanglement is only present between spins that are separated by no more than a blockade length, we show that non-classical correlations can extend much further and analyze them through quantum discord. We furthermore identify a set of seemingly critical points where the ground state approaches a crystalline state with a filling fraction that is given by the inverse of the blockade length. We analyze the scaling properties in the vicinity of this parameter region and show that the correlation length possesses a non-trivial dependence on the blockade length.

LOMB-SCARGLE PERIODOGRAM

description: Characterizing Earth-orbiting objects is crucial for Space Domain Awareness. Light curves, whichmeasureobject brightness over time, provide valuable information for this task. However, resulting from combination of several factors, their inversion is quite challenging. Different methods address this problem, including data fusion techniques, frequency spectra analysis, and multi-objective optimization. This paper proposes anarchitecture that employs the Lomb-Scargle Periodogram algorithm to extract frequency spectra from light curves and classify attitude motion based on their characteristics. Performance is evaluated using synthetic light curves generated by a numerical simulator which allows accounting for complex target shape, observation geometry, multi-temporal and multi-sensor measurements.

description: The present article demonstrates the resent research activities conducted in JAXA for turbopump inducers, focusing on flow characterizations by PIV measurements and establishment of cavitation surge prediction model. The PIV measurements successfully characterize the backflow structures in inducers. Especially, backflow vortices are captured by PIV from upstream views with a borescope. Furthermore, the study establishes a new prediction model for cavitation surge based on cavitation characteristic parameters. By integrating their dynamic properties, the model successfully predicts both frequency and onset of cavitation surge. The investigations will be further deepened to expand the insight of flow dynamics in induers.

description: This paper presents a model, which is based on the combination of the shell model of turbulence and aero-optics for the case of the buoyancy driven turbulence and turbulence in the vibrationally nonequilibrium flow. It is shown that the refractive index spectrum generated using the shell model reflects experimentally observed structure functions of temperature. Analysis of the fluctuating part of the and irradiance profiles are controlled by the rate of dissipation of the temperature variance, which depends on the level of the vibrational non-equilibrium.

description: The current lack of awareness of actual pollutants concentration in the cabin of commercial aircraft makes linking air quality and passenger\'s comfort problematic, hence dilution with external fresh air is mostly the only adopted approach to assure a good cabin air quality. This manifests in the Environmental Control System (ECS) being the most energy-intensive non-propulsive system. This study reveals that an adaptive ECS with reduced and adjustable fresh air flow ought to save fuel, along with additional sensing and filtering technologies, is capable to maintain a good level of Cabin Air Quality (CAQ). This article simulates single-aisle CAQ, tracking carbon dioxide, and a selected set of volatile organic compounds and particulate matter. Three indicators -well-being impact, measurability, and treatability -have been utilised to prioritize the targeted contaminants. Three main subsystems are modeled using a Modelica framework: the cabin, the recirculation loop and the two pressurisation and air-conditioning kits. The devised models of metabolic and ametabolic generation and deposition of the selected contaminants is able to provide insight on the operation of any ECS architecture and may aid the design of more functional CAQ sensing campaigns.

description: This paper presents some findings from refugee single mothers living in Ottawa, Canada, exploring their employment experiences and experiences as single mothers during the Covid-19 period. It also covers how to generate evidence to guide policy development, considering the access to resources and refugee single mothers' financial stability, especially during the Covid-19 pandemic. My analysis draws on six interviews with refugee single mothers. It shows that all refugee single mothers faced a difficult situation during the pandemic and post-pandemic, especially in getting employment, providing necessities for the family and caring for their children. Finally, the paper presents a theoretical and conceptual framework empirically grounded in an innovative qualitative methodological design to capture the complexities of the research, using participants’ narratives as the empirical material.

description: Since its independence in 1971, Bangladesh has struggled between being a secular state and a theocratic state. Although secularism prevails, despite 89.1% of the population being Muslim, the social fabric of society remains tumultuous. Three factors, religious education, the return of jihadists from Afghanistan, and the entry of Rohingya Muslims from Myanmar, have radicalised the community, mainly the youth, to perpetrate extremist acts.To neutralise such acts, the government has enacted various legislation and signed treaties with other countries, such as India, to share relevant information. Still, this falls short of containing extremism. Instead, extremism is becoming a significant challenge and is a serious concern at the national level. Even with the government’s efforts to contain extremism and build a harmonious society, some sections of society are becoming marginalised. Therefore, this research aims to determine how community engagement influences the curbing of extremism, as Bangladesh is a densely populated country with closely interwoven community relationships.

description: We present the results for the calculation of the forward jet vertex associated to a rapidity gap (coupling of a hard pomeron to the jet) in the Balitsky-Fadin-Kuraev-Lipatov (BFKL) formalism at next-to-leading order (NLO). We handle the real emission contributions making use of the high energy effective action proposed by Lipatov, valid for multi-Regge and quasi-multi-Regge kinematics. This result is important since it allows, together with the NLO non-forward gluon Green function, to perform NLO studies of jet production in diffractive events (Mueller-Tang dijets, as a well-known example).

description: Single-cell transcriptomics profiling has increasingly been used to evaluate cross-group differences in cell population and cell-type gene expression. This often leads to large datasets with complex experimental designs that need advanced comparative analysis. Concurrently, bioinformatics software and analytic approaches also become more diverse and constantly undergo improvement. Thus, there is an increased need for automated and standardized data processing and analysis pipelines, which should be efficient and flexible too. To address these, we develop the single-cell Differential Analysis and Processing Pipeline (scDAPP), a R-based workflow for comparative analysis of single cell (or nucleus) transcriptomic data between two or more groups and at the levels of single cells or “pseudobulking” samples. The pipeline automates many steps of pre-processing using data-learnt parameters, uses previously benchmarked software, and generates comprehensive intermediate data and final results that are valuable for both beginners and experts of scRNA-seq analysis. Moreover, the analytic reports, augmented by extensive data visualization, increase the transparency of computational analysis and parameter choices, while facilitate users to go seamlessly from raw data to biological interpretation.

description: Although for large area detectors it is crucial to find an alternative to detect thermal neutrons because of the 3He shortage, this is not the case for small area detectors. Neutron scattering science is still growing its instruments' power and the neutron flux a detector must tolerate is increasing. For small area detectors the main effort is to expand the detectors' performances. At Institut Laue-Langevin (ILL) we developed the Multi-Blade detector which wants to increase the spatial resolution of 3He-based detectors for high flux applications. We developed a high spatial resolution prototype suitable for neutron reflectometry instruments. It exploits solid 10B-films employed in a proportional gas chamber. Two prototypes have been constructed at ILL and the results obtained on our monochromatic test beam line are presented here.

description: The boom of New Space and its start-up ecosystem, alongside the evolution of the space market linked to constellations and to new destinations as the Moon and Mars, is challenging the traditional space transportation approach based on \"point-to-point\" missions with tailored launchers. ESA market and system studies [l] indicate that the most cost-effective and perform ant space transportation system on the 2025-2050 horizon could rely on an optimised fleet of reusable launchers injecting payloads on high parking orbits, combined with a \"hub and spoke\" space logistics network to reach the final orbits (e.g. constellations phasing, exploration missions ... ) and provide transportation support for in-orbit servicing. Such an ecosystem will be a system-of-systems involving a portfolio of interoperable In-Space Transportation Vehicles (ISTVs) integrating standardised interfaces to ensure their interactions. To foster the emergence of such a European in-space transportation ecosystem, that is considered as a potential game-changer for access to space, ESA Future Space Transportation is enabling its required space transportation capabilities, as rendezvous docking and in-orbit refuelling, using incremental InOrbit Demonstrations over the coming years. Following a competitive tendering, five parallel contracts are on-going on the Phase 0/A studies of Proof-of-Concept 1 (PoC-1) on in-orbit rendezvous and docking [2]. Their objective is to perform a state-of-the-art survey then trade-off on the enabling interfaces (mechanical electrical docking interfaces, operational GNC protocols, communication standards ... ), to foster a convergent approach on their standardisation, and to perform the conceptual design of the PoC-1 system-of-systems for its In-Orbit Demonstration between two ISTVs. These contracts are led respectively by D-Orbit, OHB System, S.A.B. Aerospace, Thales Alenia Space, and The Exploration Company as Prime contractors. This paper provides a synthesis of the outcomes of these Phase 0/A studies on PoC-1: in-orbit rendezvous and docking. The considerations and designs of the required interfaces will be presented and discussed, to pave the way for the standardisation of these building blocks that are cornerstones for the emergence of this end-to-end space transportation ecosystem. The ESA roadmap on in-space transportation will be continued with the next steps of PoC-1 up to its In-Orbit Demonstration (IOD) and the launch of first phases of PoC-2 on in-orbit refuelling for reusable space tugs.

description: Tgf-? ligands induce cell cycle arrest in a variety of mammalian epithelia, including in the prostate. Genetic deregulation of the downstream canonical Smad-dependent pathway is an early well-studied event in tumorigenesis, yet, in prostate cancer such mutations are rare, leaving unexplained how Tgf-? represses prostate cell proliferation. Here, we adopted a variety of pharmacological and genetic approaches to dissect the pathways controlling proliferation in mouse prostate organoids. We found that Egf signalling is a potent proliferative stimulus through the concomitant activation of both Pi3k/Akt and Mapk/Erk pathways. However, the autocrine release of the Tgf-? family ligand Activin A has a dominant role over Egf-induced proliferation by promoting the non-canonical Tak1-p38?/? axis, which leads to Mapkapk2, p16, p21, and Stat1/2 activation and cell-cycle arrest. Bypass of the proliferation barrier can spontaneously occur upon long-term culture and it is associated to aberrant Activin A signalling and DNA replication stress. Finally, orthotopic transplantation of adapted organoids into immunocompetent hosts, leads to aberrant outgrowth and the emergence of prostatic intraepithelial neoplasia (PIN). Overall, our experiments unveil how Activin A limits mouse prostate progenitor cells proliferation and provide a rationale for the frequent MAP3K7 (TAK1) and ACVR2A (Activin A type II receptor) deletions observed in human primary prostate cancers (20% in the TCGA 2015 dataset).

description: A facility for testing nanosatellites attitude determination and control systems is under development by the University of Bologna and Nautilus -Navigation in Space, under ESA coordination and funding. The facility, to be installed in ESTEC, will enable the verification of closed-loop attitude control with physical sensor stimulus and physical effects from the actuators driving the dynamics. By testing nanosatellites in such an environment, it is expected to catch issues not identified due to the compressed verification campaign typical of the New-Space approach. The manuscript reports on the project status, focusing on the driving requirements and design choices adopted.

description: Identifying and characterizing the parent phases of iron-based superconductors is an important step towards understanding the mechanism for their high temperature superconductivity. We present an investigation into the magnetic interactions in the Mott insulator La2O2Fe2OSe2. This iron oxyselenide adopts a 2-k magnetic structure with low levels of magnetic frustration. This magnetic ground state is found to be dominated by next-nearest neighbor interactions J2 and J2' and the magnetocrystalline anisotropy of the Fe2+ site, leading to 2D-Ising-like spin S=2 fluctuations. In contrast to calculations, the values are small and confine the spin excitations below ~ 25 meV. This is further corroborated by sum rules of neutron scattering. This indicates that superconductivity in related materials may derive from a weakly coupled and unfrustrated magnetic structure.

description: Humans are highly social beings which is evidenced by our desire to continually establish social relationships with each other. Healthy social relationships promote engagement in social activities and provide access to social support which greatly benefits overall health outcomes. In our research study, we provide an overview of the impact of social activities on the quality of life among nursing home residents (65+) and evaluate different aspects of social relationships on various health, physiological and psychological functioning. Evidence suggests that a level of social engagement increases life satisfaction and is also associated with a lower risk of physiological dysregulation while low levels of social engagement can negatively impact physiological and psychological functioning (Kelly et al., 2017). We utilize the Geriatric Depression Scale (GDS) survey to gather data from nursing home residents. The GDS is a tool developed as a self-report instrument utilized to screen for clinical depression among older adults (Mauk, 2018). Data collected from the surveys will be analyzed using t-test data analysis. Independent variables of interest include participation in subjective measures of social activities, social programs, and social support. The primary outcome of interest is to determine the impact of social activities on cognitive functioning, quality of life, and the number of hospitalizations. Creating programs that help older adults engage in activities and boost productivity, such as social activities, group exercise, group volunteering, etc., will contribute to a better life satisfaction and healthier aging.

description: Objective: Reference centile charts are widely used for the assessment of growth and have progressed from describing height and weight to include body composition variables such as fat and lean mass. Here, we present centile charts for an index of resting energy expenditure (REE) or metabolic rate, adjusted for lean mass versus age, including both children and adults across the life course. Design, participants and intervention: Measurements of REE by indirect calorimetry and body composition using dual-energy X-ray absorptiometry were made in 411 healthy children and adults (age range 6–64 years) and serially in a patient with resistance to thyroid hormone α (RTHα) between age 15 and 21 years during thyroxine therapy. Setting: NIHR Cambridge Clinical Research Facility, UK. Results: The centile chart indicates substantial variability, with the REE index ranging between 0.41 and 0.59 units at age 6 years, and 0.28 and 0.40 units at age 25 years (2nd and 98th centile, respectively). The 50th centile of the index ranged from 0.49 units (age 6 years) to 0.34 units (age 25 years). Over 6 years, the REE index of the patient with RTHα varied from 0.35 units (25th centile) to 0.28 units (<2nd centile), depending on changes in lean mass and adherence to treatment. Conclusion: We have developed a reference centile chart for an index of resting metabolic rate in childhood and adults, and shown its clinical utility in assessing response to therapy of an endocrine disorder during a patient’s transition from childhood to adult.

description: Compositionally tunable vanadium oxyhydrides Sr2VO4-xHx (x = 0 - 1) without considerable anion vacancy were synthesized by high-pressure solid state reaction. The crystal structures and their properties were characterized by powder neutron diffraction, synchrotron X-ray diffraction, thermal desorption spectroscopy, and first-principles density functional theory (DFT) calculations. The hydrogen anions selectively replaced equatorial oxygen sites in the VO6 layers via statistical substitution of hydrogen in the low x region (x < 0.2). A new orthorhombic phase (Immm) with an almost entirely hydrogen-ordered structure formed from the K2NiF4-type tetragonal phase with x > 0.7. Based on the DFT calculations, the degree of oxygen/hydrogen anion ordering is strongly correlated with the bonding interaction between vanadium and the ligands.

Conjugated organoboron macrocycles

Publisher: name: No Publisher Supplied

description: Organic π-conjugated systems continue to attract great interest in applications ranging from organic electronics to sensing and imaging. The introduction of main group elements to π-conjugated systems provides a means to further modify and fine-tune the electronic and optical properties of π-system. In particular, the incorporation of tricoordinate boron leads to novel optical and electronic properties due to the empty p-orbital on boron that overlaps with π-orbitals of attached aryl or other unsaturated groups. The central focus of this thesis is to investigate the incorporation of organoborane moieties into conjugated macrocycles. We developed a new boron-doped cyclophane, the hexabora[16]cyclophane, B6-FMes, in which six tricoordinate borane moieties alternate with short conjugated p-phenylene linkers. Exocyclic FMes groups provide not only good stability but make the boron centers highly electron deficient. The optical and electronic properties are compared with those of related linear oligomers and the electronic structure is further evaluated by computational methods. The studies show that B6-FMes has a low-lying and extensively delocalized LUMO and a wide HOMO–LUMO gap which could be of interest in optoelectronic applications that require wide-gap host materials.We also isolated an ambipolar π-conjugated macrocycle, B4N2-FMes, having triarylamine donors paired with highly electron-deficient bis(boryl)fluorene units. The pendent FMes groups play an important role to increase the electron acceptor character of the boron centers, thereby to manipulate the intramolecular charge transfer character (ICT) of B4N2-FMes. The photophysical and electronic properties of B4N2-FMes are evaluated in comparison to previously reported ambipolar macrocycles. Attempts at isolating the phosphorous analog B4P2-FMes in which N is replaced by P are also described. While this macrocycle could not be isolated, computational studies provide information on the geometry and electronic structure of B4P2-FMes. They reveal a distinctly different structure for B4P2-FMes with possible formation of syn- and anti-isomers due to the pyramidal environment at P (by comparison the N atoms in B4N2-FMes adopt a trigonal planar geometry). The HOMO and LUMO levels of B4P2-FMes are slightly lower than those of B4N2-FMes, but overall they are of similar energy. The affinity of B4N2-FMes for small anions suggests potential utility in anion sensor applications.Finally, we extended our studies to investigate polycationic organoboron macrocycles that contain multiple bipyridylboronium moieties. Macrocycle [B4N2-4bipy]4+ (MC1) was successfully isolated and fully characterized, but efforts at isolating the corresponding hexaboron macrocycles [B6Ar-4bipy]4+ (MC2 and MC3) have not been met with success. MC1 exhibits multi-step redox properties involving the reversible transfer of up to 10 electrons. These macrocycles are also expected to display potentially interesting stimuli-responsive and self-assembly properties.

description: ECRA thruster is a new technology of electric propulsion based on a microwave plasma accelerated in a magnetic nozzle. It represents a promising alternative to heritage technologies as it does not need a neutraliser. This brings design simplifications, cost reductions and increased compactness of the system as well as compatibility to alternative propellants. This paper reports the last research activities led at ONERA, which aim at increasing knowledge on this technology. The paper especially focuses on a thrust vectoring device using the magnetic nozzle steering. First results demonstrate an effective thrust vectoring of several degrees.

description: We present a spectroscopic study of the four extended star clusters (ESCs) in NGC 6822 based on the data obtained with Gemini Multi-Object Spectrograph (GMOS) on the Gemini-South 8.1m telescope. Their radial velocities derived from the spectra range from $-61.2 \pm 20.4$ km s$^{-1}$ (for C1) to $-115.34 \pm 57.9$ km s$^{-1}$ (for C4) and, unlike the intermediate age carbon stars, they do not display any sign of systematic rotation around NGC 6822. The ages and metallicities derived using the Lick indices show that the ESCs are old ($\geq 8$ Gyr) and metal poor ([Fe/H]$\lesssim -1.5$). NGC 6822 is found to have both metal poor ([Fe/H]$\approx -2.0$) and metal rich ([Fe/H]$\approx -0.9$) star clusters within 15 arcmin (2 kpc) from the center, while only metal poor clusters are observed in the outer halo with $r \geq 20$ arcmin (2.6 kpc). The kinematics, old ages, and low metallicities of ESCs suggest that ESCs may have accreted into the halo of NGC 6822. Based on the velocity distribution of ESCs, we have determined the total mass and the mass-to-light ratio of NGC 6822: $M_{N6822} = 7.5^{+4.5}_{-0.1} \times 10^{9} M_{\odot}$ and $(M/L)_{N6822} = 75^{+45}_{-1} (M/L)_{\odot}$. It shows that NGC 6822 is one of the most dark matter dominated dwarf galaxies in the Local Group.

description: В статье показана логика нарождающейся мироустроительной архитектоники постпандемического мира. Анализируются этапы становления в России теоретического занания о формировании многомерного, взаимозависимого и полицентричного мира. Уделено внимание практике поиска Китаем своего места в этом мире. Показываются преимущества мирового комплексного регионоведения как междисциплинарной методологической платформы анализа процессов многомерного и полицентричного мира и одновременно как этапа формирования мироустроительной теории многомерной и взаимосвязанной полицентричности. Объясняется как формируется взаимосвязанность в мире глобальных регионов, обосновываются концепции функциональности и трансрегионализма как инструменты взаимосвязанности. Уделено внимание дискуссиям о месте востоковедения в российской номенклатуре общественных наук и возможным будущим направлениям трансформации науки о международных отношениях.

Creators: name: Hilton, Sarah

description: The central focus of this thesis was to explore perinatal experiences during the COVID-19 pandemic. In the first chapter, a systematic literature review explored the experiences of parents and non-professional carers whose baby was in a Neonatal Intensive Care Unit (NICU) during the COVID-19 pandemic. Qualitative research was synthesised using a thematic synthesis approach. 14 papers were included in the review, resulting in four themes: (1) The psychological impact of having a child in NICU during the COVID-19 pandemic; (2) Relational challenges arising from having a child in NICU during the COVID-19 pandemic (3) Parents’ perceptions of information and communication during the COVID-19 pandemic; (4) Coping and support for parents during the COVID-19 pandemic. The synthesised findings demonstrated a set of related issues of key concern for parents who had a baby in NICU during the COVID-19 pandemic, with implications for policy and practice. The second chapter presents a qualitative empirical study, exploring women’s experiences of pregnancy during the COVID-19 pandemic. Data were collected via Mumsnet, an online forum where parents can share knowledge, advice, and support. Data were derived from three different timepoints during the pandemic. Thematic analysis was used to examine the data, resulting in three themes: (1) Health-related worry, anxiety, and fear; (2) Reduced safety and choice at work; (3) Family: connection versus threat. The findings outlined how being pregnant during the COVID-19 pandemic brought additional challenges, potentially increasing the likelihood of mental health difficulties for those who were pregnant during this time. In the third chapter, the critical appraisal includes the author’s reflections on reflexivity, methods, findings, the research process, implications from the findings and potential future research.

description: We present IRAM PdBI observations of the CO(3-2) and CO(5-4) line transitions from a Ly-alpha blob at z~2.7 in order to investigate the gas kinematics, determine the location of the dominant energy source, and study the physical conditions of the molecular gas. CO line and dust continuum emission are detected at the location of a strong MIPS source that is offset by ~1.5" from the Ly-alpha peak. Neither of these emission components is resolved with the 1.7" beam, showing that the gas and dust are confined to within ~7kpc from this galaxy. No millimeter source is found at the location of the Ly-alpha peak, ruling out a central compact source of star formation as the power source for the Ly-alpha emission. Combined with a spatially-resolved spectrum of Ly-alpha and HeII, we constrain the kinematics of the extended gas using the CO emission as a tracer of the systemic redshift. Near the MIPS source, the Ly-alpha profile is symmetric and its line center agrees with that of CO line, implying that there are no significant bulk flows and that the photo-ionization from the MIPS source might be the dominant source of the Ly-alpha emission. In the region near the Ly-alpha peak, the gas is slowly receding (~100km/s) with respect to the MIPS source, thus making the hyper-/superwind hypothesis unlikely. We find a sub-thermal line ratio between two CO transitions, I_CO(5-4)/I_CO(3-2)=0.97+/-0.21. This line ratio is lower than the average values found in high-z SMGs and QSOs, but consistent with the value found in the Galactic center, suggesting that there is a large reservoir of low-density molecular gas that is spread over the MIPS source and its vicinity.

CAPITALISM OR SOCIALISM: A COMPARATIVE ANALYSIS OF SUN YAT-SEN AND LENIN

description: This study aims to provide a deep perspective on the debate between two camps in the beginning ofthe 20th century: the Chinese bourgeois revolutionary ideology represented by Sun Yat-sen (^фЩ) and Marxism represented by Lenin. By studying Sun Yat-sen’s speech “Principles of People’s Livelihood and Social Revolution” and Lenin’s article “Democracy and Narodism in China,” which is in response to Sun Yatsen’s speech, this research attempts to reassess the nature of the Chinese bourgeois revolutionary road represented by the thoughts of Sun Yat-sen and remind researchers of the difficult choices between capitalist and socialist development in China as a latecomer country. This study first explains how Sun Yat-sen’s speech expressed his views on capitalism, the definition of the Principle of People’s Livelihood, and his claim of the equalization of land rights. Then, Lenin’s evaluation of Sun Yat-sen’s speech is discussed. The different views of Sun Yat-sen and Lenin on the stage of capitalism, the means and power of social revolution, and the solution of the land problem are thus presented. This study argues that the split between the Chinese Nationalist Party (KMT) and the Communist Party of China (CPC) in 1927 came less from the KMT’s betrayal of the revolutionary road than from the fundamental difference between Sun Yat-sen’s thoughts and Marxism. Although the ideology of Sun Yat-sen has an anticapitalist component, he paid attention to the use of the state, rather than the society as a tool, and reconciliation, rather than revolution to ease the gap between the rich and the poor brought by capitalism. This thinking compels us to reconsider the particularity of the development path of China.
КОНЦЕПЦИЯ «ДИСКУРСИВНОЙ СИЛЫ» И ТРАНСФОРМАЦИЯ КИТАЙСКОЙ ВНЕШНЕЙ ПОЛИТИКИ ПРИ СИ ЦЗИНЬПИНЕ

description: Укрепление международной дискурсивной силы (гоцзи хуаюйцюанъ) Китая объявлено одним из приоритетов внешней политики при Си Цзиньпине. Китайские теоретики и практики, обращаясь к работам Мишеля Фуко о дискурсе, видоизменяют их содержание, адаптируя западный концепт дискурса к реалиям возвышающегося Китая. Настоящая статья посвящена анализу содержания понятия «международная дискурсивная сила» в контексте научных дискуссий о трансформации китайской внешней политики. В первую очередь автор рассматривает вопрос, почему этот концепт носит стратегический характер, и почему именно он, а не мягкая сила, выходит на первый план в описании взаимодействия Китая с миром. Показано, как вопрос о дискурсивной силе связан с планами Пекина по реформе глобального управления и интернационализации китайских стандартов. В качестве примера в статье рассматривается дискурсивное наполнение китайской политики в Арктике, где Китай обеспечивает свои интересы не только на материальном и практическом, но и на идейном уровне. Автор приходит к выводу, что выдвижение задачи усиления «дискурсивной силы» отражает новое качество китайской внешней политики, реагирующей на усложнившуюся внешнюю среду. В китайском понимании усиление дискурсивной силы представляет собой набор инструментов, способствующих продвижению Китая в центр мировой сцены, формирующих повестку международных институтов и новые «правила игры».
ИДЕОЛОГИЧЕСКАЯ ТРАНСФОРМАЦИЯ КНР: ПАРАЛЛЕЛИ С ПОЗДНИМ СОЦИАЛИЗМОМ В СССР

description: Как правило, китаеведы, изучающие идейную сферу КНР, уделяют основное внимание буквальному смыслу идеологических концепций. Некоторые синологи применяют иной подход и исследуют идеологические высказывания не на уровне их смысла, а на уровне эффекта, который они производят. Такой подход используется и в данной статье. Автор опирается на монографию Алексея Юрчака о периоде позднего социализма в СССР и проводит параллели в развитии советской и китайской идеологии. Как и в Советском Союзе, в КНР наблюдаются признаки «перформативного сдвига» использование правильной формы идеологического языка важнее, чем смысл, который в него вкладывается. В этом отношении примечательна эпоха Ху Цзиньтао (2002-2012). Для идеологического дискурса этого периода характерно «застывание» языковой формы. При этом в Китае наблюдался относительный идейный плюрализм. Китайские интеллектуалы достаточно свободно интерпретировали официальные концепции и привносили в них новый смысл. В период Си Цзиньпина наблюдается обратный процесс партийный язык становится более «живым», а в идеологическом пространстве появляются комментарии китайского руководителя о буквальном смысле различных концепций. При этом существенно уменьшается пространство для свободных дискуссий. Автор статьи приходит к выводу, что в настоящее время система китайского социализма претерпевает процесс «реидеологизации». Это отличает ее от советской системы, которая перед обвалом прошла процесс деидеологизации.

description: This paper details design activities performed at ONERA on the Common Inlet Concept. This configuration features two turbofans fed by a common circular inlet around the fuselage, split in two parts, one half for each engine. The purpose of that kind of inlet is to ingest the whole boundary layer around the fuselage, in order to maximise the performance benefit of such an extreme BLI concept. A detailed aerodynamic design of the concept is proposed together with a far-field exergy based analysis to assess its aero-propulsive performance. On top of this, a comprehensive performance analysis of the configuration based on advanced OAD models is provided for two missions (business jet and SMR) to evaluate the benefits of the Common Inlet at aircraft level.
On embedding of repetitive Meyer multiple sets into model multiple sets

Subjects: subject: Dynamical Systems (math.DS)

description: Model sets are always Meyer sets but the converse is generally not true. In this work we show that for a repetitive Meyer multiple sets of $\mathbb{R}^d$ with associated dynamical system $(\mathbb{X}, \mathbb{R}^d)$, the property of being a model multiple set is equivalent for $(\mathbb{X}, \mathbb{R}^d)$ to be almost automorphic. We deduce this by showing that a repetitive Meyer multiple set can always be embedded into a repetitive model multiple set having a smaller group of topological eigenvalues.

Collections as Data

description: This presentation was part of a webinar introduced by the International GLAM Labs Community in October 25th, 2022 and brought together theory and practice on how to make available GLAM digital collections as datasets for publication and re-use by researchers, GLAM professionals, creative workers and other users. As the options for preparing collections as data are nearly endless, starting the implementation of the Collections as Data principle may be daunting. To support GLAM institutions to start on this journey, the presentation gives a practical overview of the steps that can be taken and presents some of the choices to be made. You will also learn about real-life examples from the National Library of Scotland, the German National Library, the Library of Congress, Europeana, KBR - Royal Library of Belgium, the Royal Danish Library and Meemoo.
