Is a 15-Minute City Within Reach? Measuring Multimodal Accessibility and Carbon Footprint in 12 Major American Cities
(2024)Land Use PolicyEnhanced efforts in the transportation sector should be implemented to mitigate the adverse effects of CO2 emissions resulting from zoning-based planning paradigms. The concept of a 15-minute city, emphasizing proximity-based planning, holds promise in reducing unnecessary travel and progressing towards carbon neutrality. However, a critical research question remains inadequately explored: to what extent is the 15-minute city concept ...Journal Article -
The combined effect of heterogeneous thermal conductivity, chemical density contrast, and heat-producing element enrichment on the stability of primordial reservoirs above the core-mantle boundary
(2024)Earth and Planetary Science LettersEarth's deep mantle hosts continental-scale enigmatic structures whose origin, characteristics, and fate are uncovered by advances in tomographic modeling, geochemical analysis, measurements of mantle mineral properties under extreme conditions, and novel methods in mantle convection modeling. Probabilistic tomography revealed that these deep mantle structures, dubbed large low shear velocity provinces (LLSVPs), are likely enriched in ...Journal Article -
Excitation of exchange spin waves in a magnetic insulator thin film at cryogenic temperatures
(2024)Journal of Physics D: Applied PhysicsSpin waves and their quanta, magnons, are promising candidates for next-generation electronic devices, due to their low-power consumption and compatibility with radio-frequency-based electronic devices. For achieving magnon-based hybrid quantum systems for quantum memory and computation, the investigation of spin-wave propagation at cryogenic temperatures is highly required. In this article, we report the excitation and detection of ...Journal Article -
CO₂ fluxes contrast between aquaculture ponds and mangrove forests and its implications for coastal wetland rehabilitation in Leizhou Peninsula, China
(2024)Agriculture, Ecosystems & EnvironmentCoastal wetlands have great potential to mitigate climate change. However, in recent decades, the construction of aquaculture ponds has degraded coastal habitats, especially mangroves. Meanwhile, the lack of synchronized monitoring of carbon dioxide (CO₂) fluxes in coastal ponds and mangroves hinders the promotion of carbon neutrality target through the implementation of coastal wetland rehabilitation. To address this issue, we deployed ...Journal Article -

HV geometry for signal comparison
(2024)Quarterly of Applied MathematicsIn order to compare and interpolate signals, we investigate a Riemannian geometry on the space of signals. The metric allows discontinuous signals and measures both horizontal (thus providing many benefits of the Wasserstein metric) and vertical deformations. Moreover, it allows for signed signals, which overcomes the main deficiency of optimal transportation-based metrics in signal processing. We characterize the metric properties of the ...Journal Article -
A Novel Construction of Distribution Function through Second-Order Polynomial Approximation in Terms of Particle Mass, Momentum and Energy
(2024)Advances in Applied Mathematics and MechanicsIn this paper, we propose a new way to construct the distribution function through the second-order polynomial approximation in terms of particle mass, momentum and energy. The new construction holds three distinguished features. First, the formulations are more concise as compared with the third-order truncated Hermite polynomial expansion which yields Grad's 13-moment distribution function; Second, all moments of the present distribution ...Journal Article -
Fabrication Procedures and Mechanical Supports of No-Insulation All-GdBCO Double Pancake Magnets in Liquid Helium
(2024)IEEE Transactions on Applied SuperconductivityThe no-insulation (NI) high-temperature superconductor (HTS) winding technique enables the fabrication of highly compact magnets with self-quench protection. NI pancake coils are implemented to develop a 28-T HTS magnet for the operation of a 792-GHz gyrotron, which is a microwave source for dynamic nuclear polarization nuclear magnetic resonance. To this end, three NI all-GdBCO double pancake (DP) magnets were fabricated using different ...Journal Article -
Nonlinearity enhanced mode localization in two coupled MEMS resonators
(2024)International Journal of Mechanical SciencesAs an intriguing phenomenon in coupled dynamic systems, mode localization has garnered considerable attention in areas such as vibration control, sensing, etc. This paper investigates mode localization in two coupled MEMS resonators in both linear and nonlinear cases through experimental and theoretical analyses. The relationship of amplitude variation or energy transfer between two resonators in mode localization is unveiled. Subsequently, ...Journal Article -
More realistic planetesimal masses alter Kuiper belt formation models and add stochasticity
(2024)IcarusMuch of the modern Kuiper belt is thought to be the result of Neptune's migration through a primordial belt of planetesimals, possibly interrupted by an instability amongst the giant planets. While most prior work has employed massless test particles to study this Kuiper belt formation process, we perform simulations here that include the gravitational effects of the primordial planetesimal belt consisting of ∼105 massive bodies. In our ...Journal Article
