Fractional List Packing for Layered Graphs
Journal of Graph Theory, EarlyView.ABSTRACT The fractional list packing number χ ℓ • ( G ) ${\chi }_{\ell }^{\bullet }(G)$ of a graph G $G$ is a graph invariant that has recently arisen from the study of disjoint list‐colourings. It measures how large the lists of a list‐assignment L : V ( G ) → 2 N $L:V(G)\to {2}^{{\mathbb{N}}}$ need to be to ensure the existence of a “perfectly ...

Knowledge and Process Management, EarlyView.ABSTRACT This study analyzes the effects of the management control systems (social networking and organic innovative culture), via bricolage and frugal innovation, in the social and economic value creation of startups with a social mission. Data from 118 Brazilian startups with a social mission were analyzed using structural equation modeling and fuzzy‐

Mathematical Methods in the Applied Sciences, EarlyView.A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Existence Analysis of a Three‐Species Memristor Drift‐Diffusion System Coupled to Electric Networks
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT The existence of global weak solutions to a partial‐differential‐algebraic system is proved. The system consists of the drift‐diffusion equations for the electron, hole, and oxide vacancy densities in a memristor device, the Poisson equation for the electric potential, and the differential‐algebraic equations for an electric network.

Hölder Regularity of the Solutions of Fredholm Integral Equations on Upper Ahlfors Regular Sets
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We extend to the context of metric measured spaces, with a measure that satisfies upper Ahlfors growth conditions, the validity of (generalized) Hölder continuity results for the solution of a Fredholm integral equation of the second kind. Here we note that upper Ahlfors growth conditions include also cases of nondoubling measures.

Explainable human‐in‐the‐loop healthcare image information quality assessment and selection
CAAI Transactions on Intelligence Technology, EarlyView., 2023 Abstract Smart healthcare applications cannot be separated from healthcare data analysis and the interactive interpretability between data and model. A human‐in‐the‐loop active learning approach is introduced to reduce the cost of healthcare data labelling by evaluating the information quality of unlabelled medical data and then screening the high ...

Naval Research Logistics (NRL), EarlyView.ABSTRACT We are concerned with the stability of a transferable‐utility cooperative (TU) game. First, the concept of core can be weakened so that the blocking of changes is limited to only those with multilateral backings. This principle of consensual blocking, as well as the traditional core‐defining one of unilateral blocking and one straddling in ...

Tactical and Strategic Risks From Supply Disruptions in Competing Supply Chains
Naval 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.

Brokering Localization: Country‐Based Pooled Funds in Humanitarian Assistance
Public Administration and Development, EarlyView.ABSTRACT This article analyzes Country‐Based Pooled Funds (CBPFs) to identify types of brokerage models and their effects on localization. CBPFs are intermediaries in the aid chain connecting donors to implementers such as the United Nations, international non‐governmental organizations (INGOs) and national NGOs (NNGOs). This paper analyzes four of the

More than proteins for empty stomachs: Wild meat in the BaTonga food system
People and Nature, EarlyView.Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.
