Abstract： “New integration”, an important point of the macroscopic information science view in the Nanjing Consensus on the Development of Information Science and Information Work (“Nanjing Consensus” for short), has become the core meaning of the construction and development of the discipline system, academic system and discourse system of information science with Chinese characteristics and has also put forward new ideas and directions for the positioning and training of information talents. This paper aims to break through the traditional training mode of information talents and explore a new training mode of applied high-level information talents relying on the framework of full information capabilities. The article adopts the methods of literature research, combination of quantitative and qualitative, comparison and analogy to dynamically analyze and study the domestic literature related to information talents training before and after the “Nanjing Consensus” was revealed. Then, starting from the framework of full information capabilities, combined with the advanced experience and policy development trajectory of domestic and foreign talents cultivation, the article summarizes the application pathways and explores the construction of a talent training system of full information capabilities. From the perspective of new integration, the training system of talents with full information capabilities focuses on the realization of multi-dimensionally transdisciplinary cooperation across time and space in discipline system, application fields, key technologies and related resources, so as to form a positive feedback effect. Under the joint influence of new technologies and new ideas, the talents with full information capabilities can quickly and comprehensively play the role of ears and eyes in the industry.

Abstract： The space reengineering of university libraries is the transformation and upgrading of library services made to meet the needs of users. By means of network research and questionnaire research, the service status of space reengineering in the libraries of 42 “Double First-Class” universities released by China’s Ministry of Education in the first round is analyzed from the aspects of space types, service functions, equipment configuration, reservation forms, use rules, contact information and opening hours. It is found that the space reengineering services of “Double First-Class” university libraries have achieved certain results, but there are still issues such as insufficient publicity and promotion, insufficient service functions, equipment configuration needed to be optimized, insufficient management system, and lack of attention to users’ needs, etc. Based on user requirements, some improvement strategies are put forward, including strengthening publicity and promotion, improving management systems, strengthening service team construction, enriching space service content, and focusing on users’ needs and experiences.

Abstract： The traditional paper reading in the age of screen reading is being strongly challenged, the circulation rate of literature in university libraries tends to decline, and improving the circulation rate of literature has become the focus of attention in the industry. It has certain theoretical and practical value to carry out research on the circulation rate of university libraries in the age of screen reading. This paper adopts the literature research method, the social survey method, the comparative research method and other research methods to deeply analyze the social cognition of paper reading and screen reading, as well as the impact of screen reading on the circulation of literature in university collections, pointing out the dilemma faced by literature circulation. Based on the research and analysis of the two reading methods of paper reading and screen reading, as well as their impact, this paper proposes that what has changed in “screen reading era”is the reading carrier and the way how readers obtain information,and the readers’ demand for target information remains unchanged. Paper reading and screen reading can coexist and develop together. Establishing the suitability evaluation system of literature resources as the traction, increasing the effective supply of literature resources as well as guiding the needs of readers reasonably are important ways for university libraries to improve the circulation rate of literature in the “screen reading era”.

Abstract： In the promotion of nationwide reading and the revitalization of rural culture, the library community has attached more importance to encouraging and guiding rural residents to participate in reading and promoting the high-quality development of rural reading. In recent years, the government and society have increased their investment and service in the construction of rural reading facilities. However, it is undeniable that the utilization rate of rural reading facilities is generally low, as well as the reading participation rate. Based on the investigation of the current situation of rural public reading in China and the analysis of the problems it faces, this paper introduces the case of rural reading development promoted by the farmers’ reading clubs in Pinghu City, Zhejiang Province. It expounds on the orientation, organizational structure, specific practices, social benefit as well as development effect evaluation of farmers’ reading clubs in many aspects and provides experience and reference for promoting grassroots reading across the country.

Abstract： From the perspective of resource orchestration, this paper takes resource structuring, resource bundling and resource leverage as the analysis framework, and investigates the status quo of 30 reading club alliances in China through web survey and content analysis. The alliance is mainly constructed by public libraries and there are three types of alliances, including contract-based alliance, center-oriented alliance and joint-oriented alliance. On the one hand, the reading club alliance achieves resource structuring through goals, organizational models, member management mechanisms and operation management systems. On the other hand, it improves the abilities of resource ownership and value co-creation to realize resource bundling. Finally, the reading club alliance seizes the opportunities for resource orchestration to promote the effectiveness of reading and brand construction. But there are still insufficiencies that need to be solved. It is necessary to improve the management mechanism to enhance the structural quality of the alliance, promote the integration and sharing of resources of the alliance to ensure the development of resource bundling and improve the effectiveness of activities to promote the value of the resources of the alliance.

Abstract： Space design plays an increasingly important role in the development of public libraries, and user-centered multi-sensory experience design has become a new research topic. The Nasushiobara City Library in Japan has designed a reading space with a sense of “forest” to stimulate the audience’s desire to learn through multi-sensory stimulation, which has brought new perceptions to the public. Taking the library’s space design as an example, this article analyzes the impact of the “forest sense” reading space on users’ various senses. Through the inductive-deductive method, it explores the dynamic changes and influences that the spatial environment brings to users in terms of sensation, emotion, and cognition. It uncovers innovative opportunities for public libraries in spatial design and redesign. In the future, the design philosophy for public library spatial design should revolve around enhancing user experiential satisfaction. This involves meticulous creation of environmental aesthetics, thoughtful consideration of audience experience, scientifically placed sensory nodes and well-planned spatial layouts to construct visually appealing, comfortable, and scientifically designed reading spaces.

Abstract： It is a major trend for university libraries to use modern information technology to enhance service efficiency. Studying the influence level of video accounts of university libraries on new media platforms is conducive to promoting the high-quality development of information services in university libraries. Taking 23 officially certified Bilibili video accounts of university libraries as research samples, this paper constructs the influence evaluation index system of those accounts from four dimensions: activity, interactivity, likability and content richness. The entropy method and the method of partial order set are used to evaluate those video accounts and obtain the Haas plot and linear ranking results of the influence of the accounts. Specific suggestions for improving the impact of Bilibili video accounts of university libraries are proposed from the four dimensions of the evaluation indexes, with a view to providing better services for university library users.

Abstract： We measure for the first time the outermost edges of the Milky Way (MW) halo in terms of the depletion and turnaround radii. The inner depletion radius, $r_\mathrm{id}$, identified at the location of maximum infall velocity, separates a growing halo from the draining environment, while the turnaround radius, $r_\mathrm{ta}$, marks the outermost edge of infalling material towards the halo, both of which are located well outside the virial radius. Using the motions of nearby dwarf galaxies within $3\mathrm{Mpc}$, we obtain a marginal detection of the infall zone around the MW with a maximum velocity of $v_\mathrm{inf, max}=-46_{-39}^{+24}\mathrm{km s^{-1}}$. This enables us to measure $r_\mathrm{id}=559\pm 107 \mathrm{kpc}$ and $r_\mathrm{ta}=839\pm 121 \mathrm{kpc}$. The measured depletion radius is about 1.5 times the MW virial radius ($R_\mathrm{200m}$) measured from internal dynamics. Compared with halos in the cosmological simulation Illustris TNG100, the factor 1.5 is consistent with that of halos with similar masses and dynamical environments to the MW but slightly smaller than typical values of Local Group analogs, potentially indicating the unique evolution history of the MW. These measurements of halo edges directly quantify the ongoing evolution of the MW outer halo and provide constraints on the current dynamical state of the MW that are independent from internal dynamics.

Abstract： The Solar System's orbital structure is thought to have been sculpted by an episode of dynamical instability among the giant planets. However, the instability trigger and timing have not been clearly established. Hydrodynamical modeling has shown that while the Sun's gaseous protoplanetary disk was present the giant planets migrated into a compact orbital configuration in a chain of resonances. Here we use dynamical simulations to show that the giant planets' instability was likely triggered by the dispersal of the gaseous disk. As the disk evaporated from the inside-out, its inner edge swept successively across and dynamically perturbed each planet's orbit in turn. The associated orbital shift caused a dynamical compression of the exterior part of the system, ultimately triggering instability. The final orbits of our simulated systems match those of the Solar System for a viable range of astrophysical parameters. The giant planet instability therefore took place as the gaseous disk dissipated, constrained by astronomical observations to be a few to ten million years after the birth of the Solar System. Terrestrial planet formation would not complete until after such an early giant planet instability; the growing terrestrial planets may even have been sculpted by its perturbations, explaining the small mass of Mars relative to Earth.

Abstract： A general covariant local field theory of the holographic dark energy model is presented. It turns out the low energy effective theory of the holographic dark energy is the massive gravity theory whose graviton has 3 polarisations, including one scalar mode and two tensor modes. The Compton wavelength is the size of the future event horizon of the universe. The UV-IR correspondence in the holographic dark energy model stems from the scalar graviton's strong coupling at the energy scale that marks the breaking down of the effective field theory.

Abstract： Thermoelastic loss is one of the main energy dissipation mechanisms in resonant systems. A careful analysis of the thermoelastic loss is critical to design low-noise resonators for high-precision applications, such as gravitational-wave detectors. This paper presents an analytical solution to the thermoelastic loss in multimaterial coated finite substrates with realistic assumptions on the model structure and the elastic fields. The mechanism responsible for thermoelastic loss is taken as a function of material properties, operating temperature and frequency, and other design parameters. We calculate the thermoelastic loss for specific applications over a wide range of frequencies (1 Hz to 10 GHz) and temperatures (1 K to 300 K), and for a variety of substrate and coating materials. The result is relevant for gravitational-wave detectors and for experiments sensitive to mechanical dissipation.

Abstract： Building accurate and predictive models of the underlying mechanisms of celestial motion has inspired fundamental developments in theoretical physics. Candidate theories seek to explain observations and predict future positions of planets, stars, and other astronomical bodies as faithfully as possible. We use a data-driven learning approach, extending that developed in Lu et al. ($2019$) and extended in Zhong et al. ($2020$), to a derive stable and accurate model for the motion of celestial bodies in our Solar System. Our model is based on a collective dynamics framework, and is learned from the NASA Jet Propulsion Lab's development ephemerides. By modeling the major astronomical bodies in the Solar System as pairwise interacting agents, our learned model generate extremely accurate dynamics that preserve not only intrinsic geometric properties of the orbits, but also highly sensitive features of the dynamics, such as perihelion precession rates. Our learned model can provide a unified explanation to the observation data, especially in terms of reproducing the perihelion precession of Mars, Mercury, and the Moon. Moreover, Our model outperforms Newton's Law of Universal Gravitation in all cases and performs similarly to, and exceeds on the Moon, the Einstein-Infeld-Hoffman equations derived from Einstein's theory of general relativity.

Abstract： Presolar grains are microscopic dust grains that formed in the stellar winds or explosions of ancient stars that died before the formation of the solar system. The majority (~90% in number) of presolar silicon carbide (SiC) grains, including types mainstream (MS), Y, and Z, came from low-mass C-rich asymptotic giant branch (AGB) stars, which is supported by the ubiquitous presence of SiC dust observed in the circumstellar envelope of AGB stars and the signatures of slow neutron-capture process preserved in these grains. Here, we review the status of isotope studies of presolar AGB SiC grains with an emphasis on heavy-element isotopes and highlight the importance of presolar grain studies for nuclear astrophysics. We discuss the sensitives of different types of nuclei to varying AGB stellar parameters and how their abundances in presolar AGB SiC grains can be used to provide independent, detailed constraints on stellar parameters, including 13C formation, stellar temperature, and nuclear reaction rates.

Abstract： Simple climate models have been around for more than a century but have recently come back into fashion: they are useful for explaining global warming and the habitability of extrasolar planets. The Climate App (https://www.climateapp.ca) is an interactive web-based application that describes the radiative transfer governing planetary climate. The App is currently available in French and English and is suitable for teaching high-school through college students, or public outreach. The beginner version can be used to explore the greenhouse effect and planetary albedo, sufficient for explaining anthropogenic climate change, the Faint Young Sun Paradox, the habitability of TRAPPIST planets and other simple scenarios. There is also an advanced option with more atmospheric layers and incorporating the absorption and scattering of shortwave radiation for students and educators wishing a deeper dive into atmospheric radiative transfer. A number of pedagogical activities are being beta tested and rolled out.

Abstract： The Messenger Interface Monte-Carlo Mappings V (M^3) is a photoionization code adopting the fully self-consistent Monte-Carlo radiative transfer technique, which presents a major advance over previous photoionization models with simple geometries. M^3 is designed for modeling nebulae in arbitrary three-dimensional geometries. In this paper, we describe the Monte-Carlo radiative transfer technique and the microphysics implemented in M^3, including the photoionization, collisional ionization, the free-free and free-bound recombination, and two-photon radiation. We put M^3 through the Lexington/Meudon benchmarks to test the reliability of the new code. We apply M^3 to three HII region models with fiducial geometries, demonstrating that M^3 is capable of dealing with nebulae with complex geometries. M^3 is a promising tool for understanding emission-line behavior in the era of SDSS-V/LVM and JWST, which will provide high-quality data of spatially-resolved nearby HII regions and highly turbulent local and high-redshift HII regions.
