Space‐Time FEM Solution of Dynamic Contact Problem With Discontinuous Velocity for Multiple Impact of Deformed Bar Using PDAS Method

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT A class of one‐dimensional impact and dynamic contact problems taking into account non‐smooth velocities is studied. The new space‐time finite element approximation of dynamic variational inequalities is suggested. The non‐smooth solution for the impact of an obstacle by an elastic bar and its energy conservation under persistency conditions ...

Free Surface Waves in Electrohydrodynamics With a Prescribed Vorticity Distribution

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Traditionally, the study of free surface flows assumed irrotationality to simplify matters, and the results seemed to have great success, notably with the Korteweg‐de Vries(KdV) equation. In the past decade, there have been attempts to remove this seemingly strong condition and replace it with a global constant vorticity equivalent to a linear

Shape Derivatives of the Eigenvalues of the De Rham Complex for Lipschitz Deformations and Variable Coefficients: Part I

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We study eigenvalue problems for the de Rham complex on varying three‐dimensional domains. Our analysis includes the Helmholtz equation as well as the Maxwell system with mixed boundary conditions and non‐constant coefficients. We provide Hadamard‐type formulas for the shape derivatives under weak regularity assumptions on the domain and its ...

Toward a Framework for Understanding Localization in Its Institutional Context: A Systems Perspective for Incorporating Local Values

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT This paper explores how we might integrate local traditional values into a systems approach for analyzing and maximizing localization in the context of foreign aid. The paper situates localization and its operationalization in the older and broader literature on the political economy of foreign aid.

Localization Through Coordination? Implementing the Humanitarian‐Development‐Peace Nexus in the Democratic Republic of the Congo

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT As a global concept and initiative, the Humanitarian‐Development‐Peace Nexus (HDPN) aims to improve integration across the traditionally siloed humanitarian, development, and security sectors, while foregrounding the involvement of local actors.

Smart Biomaterials and Dressings for the Treatment of Chronic Inflammatory Skin Diseases

open access: yesRare Metals, EarlyView.
ABSTRACT Chronic inflammatory skin diseases, encompassing immune‐inflammatory conditions and infection‐associated dermatoses, pose significant clinical challenges due to high prevalence, recurrence, and therapeutic resistance, affect over 30% of the global population.

MXene‐Based Electromagnetic Attenuation Materials in Microwave and Terahertz Bands

open access: yesRare Metals, EarlyView.
ABSTRACT MXenes exhibit considerable potential for developing high‐performance electromagnetic (EM) shielding and absorption materials operating across microwave and terahertz frequencies, due to their tunable surface chemistry and exceptional charge carrier transport properties.

Understanding Interactions Between Sustainable Development Goals Within and Between Policy Programmes: The Case of Kenya's Dairy Sector

open access: yesSustainable Development, EarlyView.
ABSTRACT Achieving Agenda 2030 depends on addressing interactions between the sustainable development goals (SDGs). In this paper, we conceptualize SDG interactions as synergies or trade‐offs, incoming or outgoing, and internal or external, and analyze how SDG 2 (Zero Hunger) interacts with other SDGs within and across policy programmes that support ...

The power of expressed humility: Early stage investors' reaction to humble entrepreneurs

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary We examine how entrepreneur‐expressed humility affects early stage investors' willingness to fund new ventures. In pitching contexts where investors rely on relational cues and implicit prototypes of entrepreneurs, we theorize three distinct pathways through which expressed humility shapes funding decisions. First, building on
