Potential and roadmap of CO_2 emission reduction in urban buildings: Case study of Shenzhen

Buildings play an increasingly important role to determine the trend of CO_2 emissions in cities. Whether CO_2 emissions from buildings can be effectively mitigated has great significance for cities to achieve climate governance goals. The study takes Shenzhen, a China's megacity, as an example to examine how the penetration of newly emerging clean technologies and consumer-to-prosumer role transition of buildings will contribute to CO_2 emission reductions. Based on a Low Emissions Analysis Platform (LEAP) model, the major results indicate that CO_2 emissions of Shenzhen's building sector could be capped by 2022-2025 and substantially decreased by more than 60% by 2030. Accelerating energy efficiency retrofitting of existing buildings and enforcing stricter design standards on new buildings could largely reduce CO_2 emissions, but still unable to prevent them from growing. The intensification of building energy-saving management and promotion of distributed renewable energy use would bring additional potentials of emission reduction, enabling a peak-reaching and a rapid downward trend of building emissions. To achieve the potentials, close cooperation and synergic efforts between multiple stakeholders are advocated for establishing intelligent energysaving management systems, decarbonizing urban power supply, and popularizing distributed rooftop photovoltaic power stations.
Note on surface growth approach for bulk reconstruction

In this paper, we show using several examples that the bulk geometry of asymptotically AdS3 spacetimes can be effectively reconstructed using an intuitive and visual method called the surface growth scheme. This new approach for bulk reconstruction was originally proposed in a recent paper, along with its explicit realization using the one-shot entanglement distillation tensor network and the surface/state correspondence. In this paper, we directly analyze the growth of the bulk minimal surfaces to implement this scheme. Our study provides further support for the surface growth approach in entanglement wedge reconstruction.
Search for a lighter neutral custodial fiveplet scalar in the Georgi-Machacek model

Many researches from both theoretical and experimental perspectives have been performed to search for a new Higgs Boson that is lighter than the 125 GeV Higgs boson, which was discovered at the LHC in 2012. In this study, we explore the possibility of constraining a lighter neutral custodial fiveplet scalar H_5~0 in the Georgi- Machacek (GM) model using the latest results of the search for a lighter Higgs boson decaying into two photons from LHC data. The custodial-singlet mass eigenstate h or H is considered to be the LHC observed 125 GeV Higgs boson. A new set of constrained parameters that is favoured by low-mass H_5~0 is proposed to generate events efficiently. The production of H_5~0 from a scan based on the constrained parameters is compared to the latest results of the search for a lighter Higgs boson decaying into two photons by the CMS Collaboration after applying theoretical constraints from the GM model and constraints from all existing relevant experimental measurements, including the recent results of the Higgs boson searches by the LHC. Numerical analyses of the surviving GM parameter space are performed. The tendencies and correlations of the GM input parameters from phenomenological studies are summarized. In addition, the discovery potential of the other interesting decay channels of this low-mass neutral custodial fiveplet scalar are discussed.
Nitric oxide negatively regulates gibberellin signaling to coordinate growth and salt tolerance in Arabidopsis

In response to dynamically altered environments, plants must finely coordinate the balance between growth and stress responses for their survival. However, the underpinning regulatory mechanisms remain largely elusive. The phytohormone gibberellin promotes growth via a derepression mechanism by proteasomal degradation of the DELLA transcription repressors. Conversely, the stress-induced burst of nitric oxide (NO) enhances stress tolerance, largely relying on NO-mediated S-nitrosylation, a redox-based posttranslational modification. Here, we show that S-nitrosylation of Cys-374 in the Arabidopsis RGA protein, a key member of DELLAs, inhibits its interaction with the F-box protein SLY1, thereby preventing its proteasomal degradation under salinity condition. The accumulation of RGA consequently retards growth but enhances salt tolerance. We propose that NO negatively regulates gibberellin signaling via S-nitrosylation of RGA to coordinate the balance of growth and stress responses when challenged by adverse environments.
Analysis of Geometrical Parameters of Tubular TY-Joints on Stress Concentration Factors Due to Axial Loads

In this paper, the influence of geometric parameters on the stress concentration factors due to three different types of axial loading on 81 TY tubular structures is studied. Our results reveal that, geometric parameters have a considerable impact on the variation of stress concentration factors on tubular TY-joints under axial loads. Thus, the highest stress concentration factor values are observed on the vertical brace than on the inclined one. The finite element results of the tubular structures were verified by parametric equations and experimental data. A parametric study was carried out by analyses using the nonlinear regression method to obtain parametric equations. These equations are used to calculate stress concentration factors and to analyse the fatigue resistance of TY-joints due to axial loads.
Numerical Study and Performance Analyses of Mems-Based Particle Velocity Sensor with Combined Inclined Rib Pair

The combined inclined rib pair (CIRP)is the first time proposed to improve the sensor performance of particle velocity sensor (PVS)by using a three-dimensional numerical method. The method is verified by the experiment results in the literature. The optimal plain channel parameters are determined as the basic sensor structure. In comparison of plain channel, both heat transfer characteristics and sensor performance are enhanced effectively by arranging the CIRP. The reason is that the high flow rate region caused by the CIRP can maintain strongly in the whole fluid field if there are enough rib pairs. Furthermore, the produced longitudinal vortex pair can get a better fluid mix, which is more conductive to heat transfer. The increasing height and number of the CIRP can improve the heat transfer characteristics, but the flow resistance will increase as well. For the purpose of finding the best overall performance, the effects of the parameters including the geometric sizes and the position of the CIRP have been investigated. The results show that PVS will get the best sensitivity when the rib length and width are 0.2 mm and 0.03 mm respectively, and the distance between rib pair and between ribs in the same pair are 0.15 mm and 0.3 mm respectively. Besides, the most suitable crossing angle is 45°. Thus, the performance of PVS can be significantly improved by this novel structure.
CO_2 Diffusivity in H_2O for Supercritical Conditions: A Molecular Dynamics Study

Supercritical H_2O/CO_2 mixtures (650 K-973 K and 25 MPa, not far away from the critical temperature and pressure of water)have recently been used as the working fluid for a novel power generation system with higher efficiency and zero pollutant emission compared to conventional coal-fired power plants. The knowledge of the diffusion of these mixtures is important for efficient design of the system process. However, both experimental and theoretical data are scarce for typical working conditions in the system. Here, we investigated both the self-diffusion and the mutual diffusion of the supercritical H_2O/CO_2 mixtures using molecular dynamics (MD)simulations. Simulations show that the mixture diffusion coefficients for supercritical conditions are more than one order of magnitude larger than those in the sub-critical region. MD results reveal that H_2O molecules prefer to gather with themselves rather than with CO_2 molecules in the near-critical region, while there is no featured molecular structure for higher temperatures in the supercritical region. Therefore, the self-diffusion of CO_2 in H_2O in the infinite-dilution regime features Arrhenius temperature dependent behavior in the supercritical region excluding the near-critical-temperature segment. These molecular interaction mechanisms also provide insights into the mutual diffusion behavior of CO_2 in H_2O, which is well described by the Darken equation in the supercritical region. Furthermore, engineering equations, namely the Speedy-Angell power-law equation and the Vignes equation, can reproduce MD simulated infinite-dilution self-diffusion coefficients and Maxwell-Stefan mutual diffusion coefficients, respectively, of the supercritical H_2O/CO_2 mixtures.
Does Industry-University-Research Cooperation Matter? An Analysis of Its Coupling Effect on Regional Innovation and Economic Development

The dislocation between regional innovation and economic development directly influences the economic effect of regional innovation. However, no in-depth researches have been made on how to solve this problem. Using data from Henan Province, China, employing geographical detector technology, this paper focuses on testing whether the industry-university-research cooperation can contribute to coordinating the relation between regional innovation and economic development. It is shown that: 1) the industry-universityresearch cooperation in Henan Province is increasing gradually, and the network presents a core-edge structure, and the coupling degree between regional innovation and economic development is spatially unbalanced, which is similar to the spatial distribution of the intensity of industry-university-research cooperation; 2) as an important approach to effectively connect scientific researches with market demands, the industry-university-research cooperation can help form an interactive, interconnected, coupled and coordinated virtuous relation between regional innovation and economic development. Compared with the cooperation between organizations of the same type and the separate innovation of organizations, the improvement of the industry-university-research cooperation level can better coordinate the relation between regional innovation and economic development; 3) the cooperative innovation model between enterprises and universities can better promote the coupling between regional innovation and economic development, compared with many industryuniversity- research cooperation models. For underdeveloped areas lacking local knowledge base, industry-university-research cooperation should be considered as a long-term development strategy, especially using the knowledge sources of external universities and scientific research institutions to enhance innovation capability and achieve economic growth.

Silver vanadate (Ag_(0.33)V_2O_5) nanorods were successfully synthesized by the pre-intercalation of Ag~+ into the interlayer of V_2O_5 through a sol-gel method,which presented a favorable electrochemical performance of high capacity,rate capacity,and cycle stability.Specifically,Ag_(0.33)V_2O_5 electrode presented a high capacity of about 311 mAh·g~(-1) at the current density of 0.1 A·g~(-1).It also delivered long-term cycling stability (144 mAh·g~(-1) after 500 cycles at 2 A·g~(-1)).The reasons for the superior electrochemical performance were the preintercalation Ag~+ extended interlayer distance,and the introduction of elemental silver improved conductivity during charge/discharge.Additionally,the Zn~(2+) storage mechanism was revealed by various characteristic measurements.The prepared Ag_(0.33)V_2O_5 nanorods from the sol-gel method were demonstrated as a promising cathode material for aqueous Zn~(2+) batteries.
Tailored lithium metal/polymer electrolyte interface with LiTa_2PO_8 fillers in PEO-based composite electrolyte

The unstable Li/PEO-based electrolyte interface in all-solid-state lithium metal batteries usually leads to high interfacial resistance,low Coulombic efficiency and fast lithium dendrites growth even under a low current density.The interface composition directly determines the interfacial integrity,dynamic Li~+/e~- transport processes and the subsequent Li~+ plating/stripping behavior;thus,it is of significance to regulate the interphase to have better safety and higher energy density for all-solid-state lithium metal batteries.Here,by incorporation of Li~+ conducting LiTa_2PO_8 fillers in PEO-based polymer electrolyte,the reaction of LiTa_2PO_8 (LTPO) particles with Li metal at the Li/polymer electrolyte interface generates an electronic conducting interphase and homogenizes the electric field for Li~+ deposition,suppressing the lithium dendrites growth.We obtain a hybrid composite electrolyte with high ionic conductivity of 1.1 × 10~(-4) S·cm~(-1) at 35 °C and an excellent interface stability with a stable cycling life of over 600 h at a current density of 0.4 mA·cm~(-2) in symmetric Li/Li cell.All-solid-state lithium metal batteries with PEO-LiTFSI-lOLTPO electrolytes deliver very stable cycling and high efficiencies.
Understanding and modifications on lithium deposition in lithium metal batteries

Lithium metal has been considered as an ultimate anode choice for next-generation secondary batteries due to its low density,superhigh theoretical specific capacity and the lowest voltage potential.Nevertheless,uncontrollable dendrite growth and consequently large volume change during stripping/plating cycles can cause unsatisfied operation efficiency and serious safety concern,restraining its commercial use for the last 40 years.As widely used lithium-ion battery is approaching its theoretical limit at present,it is increasingly urgent to develop new energy storage equipment with sufficient practical capacity.Herein,two important processes of lithium deposition,nucleation and growth on lithium metal anode are reviewed.Modified three-dimensional (3D) porous anodes with unique structure and dynamic surface conditions,as one of the most efficient designs on dendrites suppression,are specifically discussed in terms of their beneficial adjustment on the dendrite formation.Problems on current designs and prospects on future advanced porous anode are explored in the end.

A corrugated reduced graphene oxide (rGO)-supported Pd composite on carbon paper (Pd/rGO/CP) is prepared via a simple chemical reduction process combined with electrodeposition.The microstructure,morphology,and surface chemical state of the composite and its performance in H_2O_2 reduction in an acidic medium are investigated.An rGO film with ample corrugated wrinkles coated closely on CP is prepared,and Pd nanoparticles are evenly decorated on the surface of rGO/CP.The Pd/rGO/CP electrode has a low Pd loading and high catalytic performance for H_2O_2 reduction in acidic media compared to Pd/CP.An excellent mass normalized activity (11,783 A·gPd~(-1)) of the Pd/rGO/CP electrode for H_2O_2 reduction is achieved at 0 V due to the corresponding low Pd loadings.Mg-H_2O_2 semi-fuel cells using Pd/rGO/CP electrode as the cathode exhibits a peak power density of 215 mW·cm~(-2) at 60 ℃ and perfect stability during a 50-h discharge.The rGO interlayer forms a microscopic three-dimensional (3D) structure on the surface of CP,thereby improving the utilization of precious metals and the specific surface area,as well as providing more Pd sites due to the transfer of electrons to Pd.Consequently,the performance of the electrode is improved.
Quasi-two-dimensional bismuth oxychalcogenide nanoflakes as novel anode for potassium-ion batteries

Potassium-ion batteries (PIBs) are considered as the promising alternative of lithium-ion batteries,due to their abundance natural resources,high cost-effectiveness,and similar working principle.With the development of PIBs,due to the larger ionic radius of potassium compared to that of lithium,the urgent demand of suitable anode materials with steady structure and fast carrier diffusion is of primary importance.Herein,a novel quasi-two-dimensional Bi_2O_2S nanoflakes embedded into a graphene scaffold have been rational designed and delicately fabricated via a facile chemical precipitation approach at room temperature.Attributing to the layered structure and unique crystal framework structure of Bi_2O_2S,the Bi_2O_2S@carbon electrode has shown potential with superior potassium storage property,which delivers a capacity of 223.7 mAh·g~(-1) after 100 cycles at 100 mA·g~(-1) as anode for PIBs.Furthermore,combined with ex situ X-ray diffraction,Raman and X-ray photoelectron spectroscopy characterizations,the K~+ storage processes of Bi_2O_2S as well as multi-step conversion and alloying reactions were clearly revealed.
THE STABILITY OF THE DELTA WAVE TO PRESSURELESS EULER EQUATIONS WITH VISCOUS AND FLUX PERTURBATIONS

This paper is concerned with the pressureless Euler equations with viscous and flux perturbations.The existence of Riemann solutions to the pressureless Euler equations with viscous and flux perturbations is obtained.We show the stability of the delta wave of the pressureless Euler equations to the perturbations;that is,the limit solution of the pressureless Euler equations with viscous and flux perturbations is the delta wave solution of the pressureless Euler equations as the viscous and flux perturbation simultaneously vanish in the case u_-> u_+.
Effects of moisture content and dry bulk density on the thermal conductivity of compacted backfill soil

Soil backfilling and compaction are often involved in urban construction projects like the burying of power cables.The thermal conductance of backfill soil is therefore of great interest.To investigate the thermal conductivity variation of compacted backfill soil,10 typical soils sampled in Zhejiang Province of China with moisture contents of 0%-25% were fully compacted according to the Proctor compaction test method and then subjected to thermal conductivity measurement using the thermal probe method at 20 ℃.The particle size distribution and the chemical composition of the soil samples were characterized to analyze their effects on thermal conductivity.The results showed that the maximum thermal conductivity of fully compacted soils generally exceeds 1.9 W/(m·K) and is 20%-50% higher than that of uncompacted soils.With increasing moisture content,soil thermal conductivity and dry bulk density first increase and then remain unchanged or decrease slowly;the critical moisture content is greater than 20% in most cases.Overall,the critical moisture content of soils with large particle size is lower than that of those with small particle size.Quartz has the highest thermal conductivity in the soil solid phase,and the mass percentage of quartz for most soils in this study is more than 50%,while that for yellow soil is less than 30%,which leads to the thermal conductivity of the former being nearly twice as great as that of the latter in most circumstances.Based on regression analysis,with moisture content and dry bulk density as the independent parameters,the prediction formulae for the thermal conductivity of two categories of compacted backfill soils are proposed for practical applications.
Design and friction loss study of full-ocean depth oil-filled direct current motor

In this study,we designed an oil-filled motor that can be used at full-ocean depths,and investigated the friction losses caused by the rotating seal and the properties of the oil.The direct current (DC) motor is encapsulated in an aluminum alloy housing.A rubber diaphragm is used to balance the internal and external pressures so that the motor can work on the seabed without pressure difference.To study the resistance caused by the rotating seal,a numerical model of the Glyd ring and the rotating shaft was established.Results from a rotational torque test agreed with those from numerical analysis.The kinematic viscosity of four oils was measured at 1-25 ℃.Oil bath experiments in an incubator showed that the resistance from oil is highly correlated with its dynamic viscosity.Dimethicone appears to be very suitable as an insulating oil for these motors.The working characteristics of the motor were tested in a high-pressure chamber.The results showed that the motor needs to overcome higher oil resistance under higher pressure.A prototype of a pressure-adaptive motor was designed and applied successfully in the hadal zone at a water depth of more than 10000 m.
Land consolidation and eco-environmental sustainability in Loess Plateau: A study of Baota district, Shaanxi province, China

Eco-environmental sustainability is the basis for sustainable development in ecologically fragile areas. Land consolidation plays an important role in coordinating human-land relationships and achieving economic growth and eco-environment protection. Taking the Loess Plateau as the study area, this paper diagnoses the associated eco-environmental problems and their chain effect. The research results show that the overall eco-environment of the region is still relatively fragile. An eco-environment multi-subject co-management model,a scale-differentiated management model, and an elements comprehensive management model are proposed to improve the eco-environmental management efficiency after implementing land consolidation in the plateau. This paper takes the Gully Land Consolidation Project in Baota district of Yan'an city in Shaanxi province as an example to illustrate the relationship between land consolidation and eco-environmental sustainability in the Loess Plateau. Policy implications for eco-environmental protection in the Loess Plateau are proposed.
Disciplinary structure and development strategy of information geography in China

The advent of the information era has resulted in exceptional advances in geographic science. The domain of geographic science has expanded from traditional physical and human geography to physical, human, and information geography, resulting in the emergence of the field of information geography. Three subdisciplines have gradually formed,i.e., geographic remote sensing science, geographic information science, and geographic data science. With a view towards preparing a description of the disciplinary structure of geographic science for the "Development Strategy of Discipline and Frontier Research in China (2021-2035)", this article summarizes the history, definition, and disciplinary structure of information geography. The strategic layout of the discipline, along with the goals and key directions of priority development fields, are also highlighted. The insights into this new discipline provided in this paper will promote the development and application of remote sensing and geographic information within the framework of geographic science, advancing the synthesis of geographic research and the integrated development of geographic science.
