Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Triply‐Twinned Metamaterials: Unraveling the Mechanics and Failure Pathways Through High‐Resolution XCT

Advanced Materials, EarlyView.
Triply‐twinned architected lattices transform deformation from bending to stretching of struts, delivering up to threefold increases in stiffness and strength across polymeric and metallic systems. High‐resolution synchrotron XCT and image‐based simulations reveal how meta‐grain architecture, defects, and AM build orientation govern failure pathways ...

The Monotonicity of Asset Prices with Changes in Risk [PDF]

The goal of this paper is the examination of the conditions on preferences to guarantee the monotonicity of asset prices, when their returns change in the sense of first- and second-order stochastic dominances.Asset Price; Comparative Statics; First ...

Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

Advanced Materials, EarlyView.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Modelling growth and biomass of Oreochromis mossambicus in a periphyton-based aquaculture production system using secondary data

Journal of Applied Animal Research
This study was conducted to potentially optimize the sustainable culture of Mozambique tilapia (Oreochromis mossambicus) in a periphyton-based aquaculture system with supplemental feeding to aqua dams using stochastic simulation models. This was achieved

Testing for Mobility Dominance [PDF]

This paper proposes tests for stochastic dominance in mobility based on the empirical likelihood ratio. Two views of mobility are considered, either based on measures of absolute mobility or on transition matrices.

Comparing the homogeneity of income distributions using Polarization Indices [PDF]

, 2015
In the context of polarized societies, income homogeneity is linked to the frequency and the intensity of social unrest. Most homogenous countries exhibit a lower frequency of intense social conflicts and less homogeneous countries show a higher ...

Risk‐based medium‐term trading strategy for a virtual power plant with first‐order stochastic dominance constraints

IET Generation, Transmission & Distribution, 2017
Distribution systems of the future will definitely encompass numerous distributed energy resources, and thereby, the physical connection and commercial contribution among virtual power plants (VPPs) will be inevitable. Accordingly, this study proposes a methodology to address the trading strategies of a VPP in cooperation with its neighbouring VPPs ...

Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

Advanced Materials, EarlyView.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

Domestic Multinationals and Foreign-Owned Firms in Italy: Evidence from Quantile Regression [PDF]

The European Journal of Comparative Economics, 2010
This paper investigates the performance differences across and within foreign-owned firms and domestic multinationals in Italy. Used for the empirical analysis are non-parametric tests based on the concept of first order stochastic dominance and quantile
