Programmable Compliance in Small‐Diameter Vascular Grafts by Design of Melt‐Electrowritten Scaffold Architectures for In Situ Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a

Norbornene Homopolymerization Limits Cell Spreading in Thiol–Ene Photoclick Hydrogels

open access: yesAdvanced Healthcare Materials, EarlyView.
Thiol–norbornene click reactions are often used in the development of cell‐permissive 3D hydrogels. However, ene–ene crosslinks in other thiol–ene systems are known to limit permissivity. This study demonstrates the negative effects of norbornene homopolymerization on 3D cell spreading and circumvents the issue by modulating polymer degree of ...

Investigating Factors Affecting Inflation with Emphasis on the Role of Backward-Looking and Forward-Looking Expectations [PDF]

open access: yesپژوهشهای اقتصادی, 2015
Inflation is the main problem which should be overcome both by the government and economic agents. The existence of inflation in an economy causes distortion and disequilibrium in the macroeconomic variables in the forms of decreasing growth rate, rising

Double Inflation in Supergravity and the Large Scale Structure

open access: yes, 1999
The cosmological implication of a double inflation model with hybrid + new inflations in supergravity is studied. The hybrid inflation drives an inflaton for new inflation close to the origin through supergravity effects and new inflation naturally ...

The Main Determinants of Inflation in South Africa: an Empirical Investigation

open access: yesOrganizations and Markets in Emerging Economies, 2018
This study investigated the determinants of inflation in South Africa using quarterly data from 1970Q1 to 2015Q4. The study was motivated by recent trends in domestic inflation that has frequently been at the upper end of the target range of between 3 ...

Inflation in Emerging and Developing Economies: Evolution, Drivers, and Policies

open access: yes, 2018
Emerging market and developing economies, like advanced economies, have experienced a remarkable decline in inflation over the past half-century. Yet, research into this development has focused almost exclusively on advanced economies.
