3D Reconstruction of Nanoparticle Distribution in Tumor Spheroids With Volume Electron Microscopy

open access: yesSmall, EarlyView.
Understanding where nanomaterials accumulate within cells is essential for revealing their biological fate and activity. We present a quantitative imaging framework to map nanomaterials and cellular structures in three dimensions. Applied to nanoparticle‐containing tumor spheroids, the approach reveals substantial cell‐to‐cell differences in uptake ...

Depth‐Aware Machine Learning for 3D Reconstruction of Fibrous Porous Electrodes by FIB‐SEM Tomography

open access: yesSmall Methods, EarlyView.
In FIB–SEM tomography of highly porous polymeric electrodes, subsurface fibers visible through open pores are mistaken for in‐plane material, distorting 3D reconstructions. A machine‐learning‐based depth‐aware model trained on everyday photographs, combined with unsupervised clustering, isolates the exposed fiber cross‐sections without labeled data ...

A Novel Approach to Energy Management in Electric Steelworks

open access: yessteel research international, EarlyView.
Feed‐forward neural networks are exploited to estimate electric energy consumptions of the electric arc furnace and ladle furnace processes. The models are used to optimize production schedule so that more energy intensive grades are produced when the cost of energy is lower.

Radial biharmonic $k-$Hessian equations: The critical dimension

open access: yes, 2017
This work is devoted to the study of radial solutions to the elliptic problem \begin{equation}\nonumber Δ^2 u = (-1)^k S_k[u] + λf, \qquad x \in B_1(0) \subset \mathbb{R}^N, \end{equation} provided either with Dirichlet boundary conditions \begin{eqnarray}\nonumber u = \partial_n u = 0, \qquad x \in \partial B_1(0), \end{eqnarray} or Navier boundary ...

Reverse engineering strut‐and‐tie models for assessing reinforced concrete structures

open access: yesStructural Concrete, EarlyView.
Abstract Strut‐and‐tie models enable the design of reinforced concrete structures with static or geometrical discontinuities, providing interpretability and control over the load path. These models are valuable for designing discontinuity regions of new structures and for validating nonlinear finite‐element analysis results. However, developing a strut‐

Bond, tension‐stiffening, and cracking in multi‐generational recycled aggregate concrete subjected to shrinkage strains

open access: yesStructural Concrete, EarlyView.
Abstract The concrete industry is responsible for a significant portion of global waste production and multi‐generation recycled aggregate concrete (MGRAC) is a means to allow the sector to transition to a circular economy framework. To predict the behavior of MGRAC at the member level there is a need to understand the underlying mechanics of bond ...

Zero‐shot learning enabled image enhancement in Bessel beam light sheet fluorescence microscopy

open access: yesVIEW, EarlyView.
A physics‐guided, unsupervised deep learning‐based image restoration framework for Bessel beam light sheet fluorescence microscopy that suppresses side‐lobe‐induced artifacts is presented. The proposed zero‐shot approach achieved 2.2‐fold increase in signal‐to‐noise ratio and 89% contrast improvement in mouse kidney tissue images, demonstrating its ...

C2 estimates for k-Hessian equations and a rigidity theorem

open access: yesAdvances in Mathematics
We derive a concavity inequality for $k$-Hessian operators under the semi-convexity condition. As an application, we establish interior estimates for semi-convex solutions of the $k$-Hessian equations with vanishing Dirichlet boundary and obtain a Liouville-type result. Additionally, we provide new and simple proofs of Guan-Ren-Wang's results on global

Estimating the Common Output Cycle in Australia

open access: yesAustralian Economic Review, EarlyView.
ABSTRACT Background/Objective This study develops a statistical measure of Australia's common output cycle and investigates the extent to which cyclical fluctuations are shared across industries. It also evaluates whether the common output cycle provides useful information for forecasting inflation.

Take Me Home, Country Roads: Choosing Autonomous EVs Over Personal Aviation

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This paper investigates the potential long‐run effects of autonomous and electric vehicles, and a carbon tax, on personal domestic aviation demand in Australia. We estimate a discrete choice disutility model with two travel modes—car and air—using Australian National Visitor Survey data and Bayesian priors. We use multiplicative Fréchet errors,
