Bulk-type all-solid-state lithium batteries (ASLBs) are considered a promising candidate to outperform the conventional lithium-ion batteries. Unfortunately, current technology level of ASLBs is in stage infancy terms cell-based (not electrode-material-based) energy densities and scalable fabrication. Here, we report on first ever bendable thin sulfide solid electrolyte films reinforced with mechanically compliant poly(paraphenylene terephthalamide) nonwoven (NW) scaffold, which enables...
Bouc–Wen class models have been widely used to efficiently describe smooth hysteretic behavior in time history and random vibration analyses. This paper proposes a generalized model with sufficient flexibility shape control highly asymmetric hysteresis loops. Also introduced is mathematical relation between the shape-control parameters slopes of loops, so that can be identified systematically conjunction available parameter identification methods. For use nonlinear analysis by equivalent...
Bounds on system probability in terms of marginal or joint component probabilities are interest when exact solutions cannot be obtained. Currently, bounding formulas employing unicomponent available for series and parallel systems, bi- higher-order systems. No theoretical exist general It is shown this paper that linear programming (LP) can used to compute bounds any level information the probabilities. Unlike bicomponent bounds, LP independent ordering components guaranteed produce...
An ordered mesoporous WO(3-X) with high electrical conductivity (m-WO(3-X)) was prepared and evaluated as an anode material for lithium ion batteries (LIBs). Ordered tungsten trioxide (m-WO(3)) identical pore structure to that of m-WO(3-X) bulk (b-WO(3-X)) the comparison purpose. electrode exhibited a reversible capacity (748 mAh g(-1), 6.5 Li/W) volumetric (∼1500 cm(-3)), which is comparable Li metal itself (ca. 2000 cm(-3)). Also, improved rate capability good cyclability were observed in...
This paper studies a non-random-walk Markov Chain Monte Carlo method, namely the Hamiltonian (HMC) method in context of Subset Simulation used for reliability analysis. The HMC relies on deterministic mechanism inspired by dynamics to propose samples following target probability distribution. alleviates random walk behavior achieve more effective and consistent exploration space compared standard Gibbs or Metropolis-Hastings techniques. After brief review basic concepts its computational...
Abstract Fine needle aspiration (FNA) is the procedure of choice for evaluating thyroid nodules. It indicated nodules >2 cm, even in cases very low suspicion malignancy. FNA has associated risks and expenses. In this study, we developed an image analysis model using a deep learning algorithm evaluated if could predict with benign results. Ultrasonographic images cytologic or histologic results were retrospectively collected. For training, 1358 (670 benign, 688 malignant) nodule input into...
Structural failures caused by a strong earthquake may induce large number of casualties and huge socioeconomic losses. To design structure that can withstand such events, it is essential to accurately estimate the nonlinear structural responses ground motions. As replacement an onerous complex time history analysis, simple regression-based equations have been widely adopted in routine engineering practices. It is, however, noted response prediction deterministic, which cannot quantify...
Abstract The chemical composition significantly affects the inherent electrical surface properties of graphite and SiO electrodes, which further, alters thermal stability solid electrolyte interphase (SEI) on negative electrodes. Because work function edge plane is lower than that 2 ‐dominant electrode when initially lithiated, charge transfer toward hindered by high . Given increased solubility SEI film SiO, makes it vulnerable to self‐discharge at higher temperatures graphite, electrodes...
Formation of the solid electrolyte interphase (SEI) on hard carbon electrode significantly influences performance batteries, in terms cycle performance, calendar life, and power characteristics. In sodium-ion batteries (SIBs), energetically inferior SEI formation mechanism, compared with lithium-ion (LIBs), results a thin, thermally vulnerable, less passivating electrode. Notably, for SIBs have higher lowest unoccupied molecular orbital (LUMO) energy level Na-solvated ethylene carbonate...
Abstract The persistent decomposition of electrolytes on graphite and silicon electrodes in lithium‐ion batteries (LIBs) is typically mitigated by the formation a solid electrolyte interphase (SEI). However, inadequate chemo‐mechanical degradation SEI leads to re‐exposure electrode electrolyte, contributing deterioration LIBs. To address this issue, tris (2,4‐pentanedionato)indium(III) (InAc) incorporated into work function tailoring additive. While conventional additives strengthen...

The flow capacity of a transportation network can be reduced significantly if its constituent bridges are damaged by natural or man-made hazards. For rapid risk-informed decision making on hazard mitigation and response, it is therefore essential to have capability predict the post-hazard efficiently accurately. However, this challenging task due uncertainty in hazards structural damage, complex nature analysis. Moreover, bridge structures may experience significant deterioration over their...
