Highly Conductive Networks Encapsulated Borohydride Electrolytes Enabling Superior High Rate Performance for All‐Solid‐State Li‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A nanoscale ZrB2/LiCl network encapsulated LiBH4 solid electrolyte was prepared by mechanically reacting LiBH4 with ZrCl4. Such a composite solid electrolyte exhibits fast ionic conduction and high critical current density. More importantly, the resultant solid electrolyte enables unprecedented cyclability of Li|LiNbO3@LiCoO2 and Li|TiS2 full cells at ...

Numerical Investigation of Aerodynamic Interactions in a Twin-Propeller Compound Helicopter

open access: yesAerospace
High-speed compound helicopters surpass the forward-speed limits of conventional helicopters and expand the flight envelope, yet close multi-component integration induces complex aerodynamic interference, whose underlying mechanisms and evolution with ...

Deformable Overset Grid for Unsteady Aerodynamic Simulation

open access: yes54th AIAA Aerospace Sciences Meeting, 2016
A deformable overset grid method was proposed to simulate the unsteady aerodynamic problems with multiple flexible moving bodies. This method uses an unstructured overset grid locally coupled with mesh deformation to achieve both robustness and efficiency. The overset grid hierarchically organizes the sub-grids into CLUSTERs and LAYERs, allowing for

Volatility Formation in Dairy Futures: Fundamentals, Public Information, and Processing Ambiguity

open access: yesJournal of Futures Markets, EarlyView.
ABSTRACT Class III milk futures cash‐settle to an administered price based on weekly component prices, creating a predictable within‐month flow of settlement‐relevant information. This paper studies drivers of cross‐month variation in realized volatility in this formula‐settled market.

ERA5 Can Overstate Changes in the Frequency of Extreme Heat: A New Zealand Case Study

open access: yesInternational Journal of Climatology, EarlyView.
ERA5 reproduces broad patterns of summer warming across New Zealand but underestimates temperature variability and warm‐tail extremes, biasing estimates of extreme heat risk. ABSTRACT Summertime temperature extremes exert profound impacts on human health, ecosystems, and infrastructure, yet their characteristics and drivers remain poorly quantified in ...

NTECARS: A Nonthermal Equilibrium CARS Spectra Fitting Code

open access: yesJournal of Raman Spectroscopy, EarlyView.
We present NTECARS, an open‐source code written in Julia for the calculation and fitting of CARS spectra under nonequilibrium conditions. Rovibrational distributions can be flexibly modeled and fitted for different use cases. The code currently implements CO2$$ \mathrm{C}{\mathrm{O}}_2 $$ and N2$$ {\mathrm{N}}_2 $$ molecules and is validated under ...

Delayed Detached-Eddy Simulations of Aerodynamic Variability During Carrier-Based Aircraft Landing with a Domain Precursor Inflow Method

open access: yesJournal of Marine Science and Engineering
Flight tests and wind tunnel experiments face difficulties in investigating the impact of aircraft carrier air-wake on the landing process. Meanwhile, numerical methods generally exhibit low overall computational efficiency in solving such problems.

Transferable Hot‐Deformation Flow‐Curve Modeling Across Steels Through Transfer Learning

open access: yesMaterials Genome Engineering Advances, EarlyView.
We propose a transferable sequence model that moves steel hot‐deformation ML beyond the “one‐case, one‐model” paradigm. Pretrained across compositions/windows and personalized with four extreme‐condition curves, it improves accuracy and robustness in 10‐fold evaluation.

Tactical and Strategic Risks From Supply Disruptions in Competing Supply Chains

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Supply chain disruptions can lead to both tactical (i.e., loss of short‐term sales during a disruption) and strategic (i.e., loss of long‐term market share) consequences. We model the impact of a supply disruption on competing supply chains in which two firms compete for a limited backup supply.

Optimal Designs and Inspection Time Decisions for Gamma Accelerated Degradation Tests

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT This study analytically derives optimal designs for gamma accelerated degradation tests while incorporating inspection time as a design variable under both D‐ and V‐optimality criteria. Under D‐optimality, we prove that the optimal design allocates test units exclusively to the lowest and highest stress levels and adopts the longest inspection
