A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

open access: yesAdvanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Civil war theory testing: How greed, horizontal inequalities, and institutions explain the Yemeni civil war between 2004 and 2009?

open access: yesKöz-gazdaság, 2019
This article applies a comparative design to test the explanatory power of formal quantitative models of civil war. It examines the grievance, horizontal inequalities, and institutional models of civil war through the case study of the Yemeni civil war ...

Continuous Stiffness Graded Metal–Ceramic Femoral Stems: UMAT‐Based Design and Finite Element Assessment

open access: yesAdvanced Engineering Materials, EarlyView.
Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...

Exploring the Determinants of Civil War in Ethiopia: A Synthetic Approach

open access: yesSAGE Open
This study provides a comprehensive analysis of the factors determining the onset of civil war in Ethiopia from 1974 to 2023, utilizing logistic regression models that incorporate variables from both the greed and grievance approaches.

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

open access: yesAdvanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Civil war and the state of nature in Hobbes [PDF]

open access: yesSociološki Pregled, 2016
The paper deals with one of the important questions of Hobbes's philosophy, the relationship between his theoretical model of the state of nature and the historical phenomenon of civil war, which profoundly marked Hobbes's life as well as his thought ...

From Geometry to Function: Programmable Mechanical Response in 3D‐Printed Adipose‐Inspired Soft Metamaterials

open access: yesAdvanced Functional Materials, EarlyView.
Geometry‐driven design of soft cellular metamaterials is systematically investigated by combining experiments, finite element modeling, and statistical prediction. The study quantifies how unit cell geometry and material properties govern stiffness, instability, densification, and energy absorption.

Pre-war grievances and violence against civilians in civil wars. Evidence from the Spanish Civil War in Catalonia.

open access: yesInternational Journal of Conflict and Violence, 2018
This article claims that the role of pre-war grievances as a predictor of violence against civilians in civil wars may have been systematically underestimated because the “grievance hypothesis” has not been properly tested.

Stacking Fault Complexions in AgSbTe2 Thermoelectrics With Enhanced Electrical Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
Atomic‐scale characterization resolves stacking fault complexion in AgSbTe2, showing Te and Sb segregation along with lattice dilation. Their enhanced effects on phonon scattering are modeled analytically. Although most defects also impede electron transport, local four‐point‐probe measurements reveal higher electrical conductivity at stacking fault ...
