A Theoretical Investigation on Coupled Mass‐charge Transport in a Binary Fluid

Advanced Theory and Simulations, EarlyView.
This study presents a theoretical framework for coupled mass‐charge transport in binary fluids using molecular dynamics simulations. By deriving governing equations from conservation laws and Onsager's theory, the approach introduces generalized diffusivity and electrostatic friction terms.

Local regularity for parabolic nonlocal operators

, 2013
Weak solutions to parabolic integro-differential operators of order $\alpha \in (\alpha_0, 2)$ are studied. Local a priori estimates of H\"older norms and a weak Harnack inequality are proved. These results are robust with respect to $\alpha \nearrow 2$.

Protected Chaos in a Topological Lattice

Advanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

Materials Selection Principles for Designing Electro‐Thermal Neurons

Advanced Electronic Materials, EarlyView.
Materials property – performance relations are established for new and old electrical materials leveraged as electro‐thermal oscillators emulating neuron dynamics. Robust, reconfigurable, high frequency, low power characteristics are explicitly tied to highly nonlinear electrical transport, small specific heat, and greater electrical than thermal ...

Increasing sedentary time, minimum dietary energy requirements, and food security assessment

Applied Economic Perspectives and Policy, EarlyView.
Abstract We compute corrections for sedentary behavior in physical activity levels (PALs) and incorporate them along with corrections for over estimation of basal metabolic rates (BMRs) into threshold caloric intakes, known as minimum dietary energy requirements (MDERs).

King and Cochrane: The technological treadmill and racial inequity in US agriculture

Applied Economic Perspectives and Policy, EarlyView.
Abstract Between 1920 and 1969, the number of Black farmers in the US decreased from 14% of all operators to 4%. Using Martin Luther King Jr.'s critique of agricultural policy and Willard Cochrane's theory of the technological treadmill, we explore how racial discrimination was linked to policies that led to structural change in US agriculture.

Beyond subsistence? The role of rural cooperatives in driving smallholder commercialization in Ethiopia

Agribusiness, EarlyView.
Abstract The transition from subsistence to market‐oriented agriculture holds the potential to boost rural economic progress and improve the well‐being of the rural poor in developing countries. Despite this potential, there is limited understanding of the key drivers for smallholder commercialization. In this study, we utilize comprehensive three‐wave

Are all meats substitutes? A basket‐and‐expenditure‐based approach

Agribusiness, EarlyView.
Abstract This study examines the relationship among animal‐based meat and plant‐based meat alternatives (PBMAs) using a basket‐and‐expenditure‐based choice experiment. In particular, we examine whether animal‐based meat products are substitutes or complements with PBMAs.

Foreign labor, peer‐networking and agricultural efficiency in the Italian dairy sector

Agribusiness, EarlyView.
Abstract While the presence of immigrants in the agricultural sector is widely acknowledged, the empirical evidence on its economic consequences is lacking, especially from a microeconomic perspective. Using the Farm Accountancy Data Network panel data for Italian dairy farms in the period 2008–2018, the present study investigates the relationship ...

Agricultural Diversification at the Margin. Strategies and Determinants in Italian Mountain and Remote Areas

Agribusiness, EarlyView.
ABSTRACT This paper explores the convergence in on‐farm diversification strategies of agricultural holdings, between remote areas and more central ones. Using Italian farm‐level data, we explore the determinants of diversification strategies across farms.
