The spatial-temporal evolution characteristics and influencing factors of the coupling between the industrial chain and innovation chain in China

Exploring the theoretical logic, development characteristics and improvement paths of the deep coupling of innovation chains and industrial chains (two-chain) is of great importance for building a modern industrial system and developing productive forces. However, empirical evidence on the spatial-temporal characteristics and influencing factors of two-chain coupling is still lacking. In this study, the degree of coupling coordination model is applied to assess the degree of two-chain coupling in China using provincial panel data from 2013 to 2022. In addition, spatial analysis is applied to investigate the spatial-temporal evolution characteristics of the variables in question. On this basis, the fuzzy set qualitative comparative analysis (fsQCA) method is applied to identify influential factors. The results indicate that: (1) Temporally, the coupling level of the two-chain shows a consistent upward trend and gradually develops a distribution pattern characterized by high values in the east and weak values in the west. (2) Spatially, there is a significant positive spatial correlation between the two-chain coupling. (3) In terms of drivers, the increase in two-chain coupling is attributed to multiple factors. Three models can be identified: human-driven, capital-driven and information-driven, which are influenced by the cooperation between government and market. The novelty of this article lies in its exploration of the theoretical logic and developmental characteristics of two-chain coupling, while empirically demonstrating its driving factors. This study provides a new perspective for governments and relevant departments to improve two-chain linkages and promote economic development.

Genetic Coupling of Mate Recognition Systems in the Genomic Era.

The concept of "genetic coupling" in mate recognition systems arose in the 1960s as a potential mechanism to maintain coordination between signals and receivers during evolutionary divergence. At its most basic it proposed that the same genes might influence trait and preference, and therefore mutations could result in coordinated changes in both traits. Since then, the concept has expanded in scope and is often used to include linkage or genetic correlation between recognition system components. Here we review evidence for genetic coupling, concentrating on proposed examples of a common genetic basis for signals and preferences. Mapping studies have identified several examples of tight genetic linkage between genomic regions influencing signals and preferences, or assortative mating. Whether this extends as far as demonstrating pleiotropy remains a more open question. Some studies, notably of Drosophila, have identified genes in the sex determination pathway and in pheromonal communication where single loci can influence both signals and preferences. This may be based on isoform divergence, in which sex- and tissue-specific effects are facilitated by alternative spicing, or on regulatory divergence. Hence it is not clear that such examples provide compelling evidence of pleiotropy in the sense that "magic mutations" could maintain trait coordination. Rather, coevolution may be facilitated by regulatory divergence but require different mutations or coevolution across isoforms. Reconsidering the logic of genetic coupling, it may be that pleiotropy could actually be less effective than linkage if distinct but associated variants allow molecular coevolution to occur more readily than potentially "unbalanced" mutations in single genes. Genetic manipulation or studies of mutation order effects during divergence are challenging but perhaps the only way to disentangle the role of pleiotropy versus close linkage in coordinated trait divergence.

The Role of Vocational Education in the Integration of Culture and Tourism in the Information Age and Its Implementation Paths

Abstract This paper constructs the coupling logic of the two systems of vocational education and cultural tourism with the joint action of external and internal driving forces. It contributes to the coupling of the two systems through the synergistic relationship of same-frequency resonance and applies dimensionless processing to data checking and data cleaning of vocational education data. The coupling coordination development level of vocational education and the cultural tourism industry can be measured using the modified coupling coordination degree model. An empirical study of the coupling coordination degree of vocational education and cultural tourism industry in Province G is conducted using the entropy value method. The results show that the coupling and coordination degree of vocational education and cultural tourism system in province G shows a decreasing trend from 2013 to 2019, and the coupling and coordination degree between the development level of the cultural tourism industry and vocational education gradually rises to 0.658388 in 2022 after 2019, and the interaction between the two is gradually obvious. The integration of industry and vocational education in cultural tourism is promoted by this paper through valuable references and drawable ideas.

A 35 V–5 V monolithic integrated GaN-based DC–DC floating buck converter

The paper presents the development of a GaN DC–DC power converter with a pre-driver module and power device based on a monolithic integrated GaN E/D-mode metal–insulator–semiconductor high electron mobility transistors (MIS-HEMTs) platform. The pre-driver module with direct coupled field effect transistor logic circuit structure has been monolithically integrated with a GaN power transistor on a Si-based AlGaN/GaN commercial epitaxial wafer. The MIS-HEMTs structure adopts an insulated gate dielectric layer to suppress the leakage current and increase gate voltage robustness. The GaN-based floating buck converter employs a 1 mH inductor and a 9 μF capacitor to achieve 35 V–5 V power conversion. As a result, the pre-driver module is capable of delivering a 10 V driving voltage. GaN monolithic integration of the pre-driver module and power device can reduce the system area in the DC–DC application, which allows for an integrated chip size of 1.8 mm2.

A Biocompatible Supercapacitor Diode with Enhanced Rectification Capability towards Ion/Electron Coupling Logic Operations.

The main challenge faced by the forthcoming human-computer interaction is that biological system and electronic device adopt two different information carriers, i.e., ions and electrons, respectively. To bridge the gap between these two systems, developing ion/electron coupling devices for logic operation is a feasible and effective approach. Accordingly, we herein develop a supercapacitor-based ionic diode (CAPode) that takes electrochemically amorphized molybdenum oxide as the working electrode. Benefiting from its unique size and charge dual ion-sieving effects, the molybdenum oxide electrode exhibits a record-high rectification ratio of 136, which is over 10 times higher than those of reported systems. It also delivers an ultrahigh specific capacitance of 448 F g-1 and an excellent cycling stability of up to 20,000 cycles, greatly outperforming those of previous works. These excellent rectification capability and electrochemical performances allow the as-built CAPode to work well in AND and OR logic gates, validating great potential in ion/electron coupling logic operations. More attractively, the superior biocompatibilities of molybdenum oxide and relevant constituent materials enable the constructed CAPode to be applied as bioelectronics without regard to biosafety, paving a new way towards forthcoming human-computer interaction.

Finally, through the positioning of characteristic vocational undergraduate education, the construction of standardized systems, and the “community of destiny” Implement and improve the integration of vocational and general education to explore the practical way of social recognition of vocational undergraduate education, and provide basic theory and practice for the realization of the development goals of vocational undergraduate education in the “Guidelines”.

Lane Selection Model Based on Phase-Field Coupling and Set Pair Logic

Intelligent and connected driving (ICD) is an effective method of the vehicle’s active safety and traffic efficiency. Lane-changing is the critical part of ICD behavior and the basic content of traffic flow theory. Lane selection is the most important during lane-changing, which has a critical influence on traffic safety and efficiency. Focusing on the development of ICD technology, a lane selection model based on phase-field coupling and set pair logic is proposed. In this model, the method of phased-field coupling is used to comprehensively analyze the full information of lanes with the interaction between cluster vehicles considering driving propensity. The certain and uncertain human-vehicle-environment information is fully explored using the method of set pair logic. In the lane selection model, the lane utility and utility gains of lane-changing are calculated to select the candidate target lane. And the overall satisfaction is analyzed to determine the target lane as the final strategy. The proposed lane selection model constructed in this research fully considers the development of ICD technology and adapts to the requirement of an Intelligent and Connected Vehicle. This research could provide a theoretical basis for vehicle autonomous behavior decision-making and ICD.

A Train Protection Logic Based on Topological Manifolds for Virtual Coupling

Virtual coupling is a promising innovation aimed at increasing railway capacity. Compared to current railway signaling systems, it allows two or more trains to run with reduced headway between them. However, such reduced headways are a challenge to safety. In this work we consider this challenge by formally describing and verifying an approach to virtual coupling. We propose a general modeling method based on topological manifolds to describe the protection logic for virtual coupling train control systems. We also describe the basic train control elements in topological terms and analyze the line condition of our virtual coupling logic. We establish that the line condition safety requirements and its representation as a manifold are equivalent and further provide a formal definition of the concept of a movement authority with manifold notations. This allows us to consider the dynamic behavior of trains and a series of theorems that establish the correctness of our protection logic for virtual coupling. Finally, we apply the presented methods to a case study. The results show that the proposed method provides a suitable way to realize a virtual coupling logic safely.

Austen, Gaskell, and the Politics of Domestic Fiction

AbstractThis essay offers a significant reconceptualization of Jane Austen’s influence on political novelists of the mid-nineteenth century by examining Elizabeth Gaskell’s extensive use of Pride and Prejudice (1813) in her novel North and South (1855). At a moment when the political dimensions of Austen’s fictions were fading to obscurity, Gaskell drew on Austen’s portrayal of domestic relationships to underscore their relevance to “public” problems. On this view, the Austenian courtship plot does not contain political anxieties so much as animate them, with the logic of complementary coupling providing a formal and thematic model for the dialectical engagements necessary for navigating social conflict. At the same time, Gaskell uses Austenian motifs to dramatize the “marriageability” of different generic frameworks during a time of regional fragmentation while also envisioning Austen as a parental figure whose legacy called for continuing negotiation.

Near-Zero-Index Slabs on Bloch Surface Wave Platform for Long-Range Directional Couplers and Optical Logic Gates.

Near-zero-index materials and structures, with their extraordinary optical behaviors of phase-free propagation resulting in directional radiation, provide a possible approach for directional coupling and optical logic gates in photonic integrated circuits. However, the radiation from the near-zero-index structures is limited to a short range of a few hundreds of nanometers. A Bloch surface wave (BSW), an electromagnetic surface wave that can be excited at the interface between an all-dielectric multilayer and a dielectric medium with a low-loss optical mode, provides a solution to increase the propagation length. In this work, we present a nanostructured near-zero-index slab integrated on the all-dielectric metal-free BSW platform for long-range surface wave radiation. By employing the long-range directional surface-wave radiation, a directional coupler and optical logic gates based on the BSW near-zero-index slabs are realized. The proposed directional couplers achieve long coupling distances (the electric-field magnitude ratio between the input slab and output slab is 0.22 with a 50 μm coupling distance), which is 2 orders of magnitude longer than that of conventional directional couplers based on evanescent wave coupling. By controlling the interference pattern of the BSW between the slabs, the XOR logic gate is experimentally demonstrated with a significant extinction ratio of 27.9 dB at telecommunications wavelengths. The BSW near-zero-index logic gates and the directional coupler with long-range light propagation provide an approach to the development of photonic integrated circuits and metal-free surface wave-based applications.

Impact of Penetrations of Connected and Automated Vehicles on Lane Utilization Ratio

Lane Utilization Ratio (LUR), affected by lane selection behavior directly, represents the traffic distribution on different lanes of road section for a single direction. The research on LUR, especially under Penetration Conditions of Connected and Automated Vehicles (PCCAV), is not comprehensive enough. Considering the difficulty in the conduction of real vehicle experiment and data collection under PPCAV, the lane selection model based on phase-field coupling and set pair logic, which considers the full-information of lanes, was used to carry out microscopic traffic simulation. From the analysis of microsimulation results, the basic relationships between Penetration of Connected and Automated Vehicles (PCAV), traffic volume, and Lane-Changing Times, also that between PCAV, traffic volume, and LUR in the basic section of the urban expressway were studied. Moreover, the influence of driving propensity on the effect of PCAVs was also studied. The research results could enrich the traffic flow theory and provide the theoretical basis for traffic management and control.

Modeling Method for the Coupling Relations of Microgrid Cyber-Physical Systems Driven by Hybrid Spatiotemporal Events

The essence of the microgrid cyber-physical system (CPS) lies in the cyclical conversion of information flow and energy flow. Most of the existing coupling models are modeled with static networks and interface structures, in which the closed-loop data flow characteristic is not fully considered. It is difficult for these models to accurately describe spatiotemporal deduction processes, such as microgrid CPS attack identification, risk propagation, safety assessment, defense control, and cascading failure. To address this problem, a modeling method for the coupling relations of microgrid CPS driven by hybrid spatiotemporal events is proposed in the present work. First, according to the topological correlation and coupling logic of the microgrid CPS, the cyclical conversion mechanism of information flow and energy flow is analyzed, and a microgrid CPS architecture with multi-agents as the core is constructed. Next, the spatiotemporal evolution characteristic of the CPS is described by hybrid automata, and the task coordination mechanism of the multi-agent CPS terminal is designed. On this basis, a discrete-continuous correlation and terminal structure characteristic representation method of the CPS based on heterogeneous multi-groups are then proposed. Finally, four spatiotemporal events, namely state perception, network communication, intelligent decision-making, and action control, are defined. Considering the constraints of the temporal conversion of information flow and energy flow, a microgrid CPS coupling model is established, the effectiveness of which is verified by simulating false data injection attack (FDIA) scenarios.

A 96-MB 3D-Stacked SRAM Using Inductive Coupling With 0.4-V Transmitter, Termination Scheme and 12:1 SerDes in 40-nm CMOS

A 28.8-GB/s 96-MB 3D-stacked SRAM is presented. A total of eight SRAM dies, designed in a 40-nm CMOS process, are vertically stacked and connected using an inductive coupling wireless link with a low-voltage NMOS push-pull transmitter that reduces the power of the link by 35% with a 0.4-V power supply. The SRAM utilizes an inverted bit insertion scheme that compensates for the degradation of the first transmitted bit, a coil termination scheme that aims to eliminate the ringing of 3D inductive coupling bus, and a 12:1 SerDes that minimizes power consumption and area overhead in inductive coupling channels. Low-power, large-capacity, 3-cycle latency 3D-stacked SRAM for a DNN accelerator is achieved with the combination of these techniques to serve as a replacement of 3D-stacked DRAM. The performance of the proposed 3D-SRAM is compared with HBM DRAM and achieves more than 50% lower energy consumption. The scaling scenario of the SRAM module is discussed in light of the scaling of the inductive coupling technology and logic process.

Efficient Dipole Coupled Nanomagnetic Logic in Stress Induced Elliptical Nanomagnet Array

This letter presents an efficient dipole coupled nanomagnetic logic scheme clocked by voltage-induced stress. The logic signals can be transmitted to an array of eight elliptical nanomagnets in one cycle. Transmission speed is increased 1-2 times versus the conventional stress scheme while the required stress is reduced. Micromagnetic simulations illustrate that both increasing the tilt angleof the electrode pair and decreasing the nanomagnet thickness can reduce the stress. When the nanomagnet thickness is 8 to 12 nm and the tilt angle of the electrode pair is 8° to 10°, it is a tradeoff considering the stress, reliability, and fabrication.
