Optimal Fiscal Policy in an Economy Facing Socio-Political Instability [PDF]

open access: yes
We present a model of optimal government policy when policies may exacerbate socio-political instability (SPI). We show that the optimal policy that takes into account SPI transforms a standard concave growth model into a model with both a poverty trap ...

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Photoactivated Proximity Protein Labeling Reveals Enhanced Tumor Retention of a D‐Peptide‐Ruthenium Prodrug Conjugate

open access: yesAdvanced Healthcare Materials, EarlyView.
Six stereoisomeric ruthenium‐peptide conjugates were synthesized and characterized, which showed high potential in photoactivated chemotherapy (PACT) and proximity protein labeling. Abstract Amino acid chirality is known to influence the biological properties of peptide‐containing prodrugs.

Knowledge Codification and Endogenous Growth Theory

open access: yes, 2007
The present thesis develops a formal model of endogenous growth that incorporates costly knowledge codification as a means of intergenerational knowledge transfer. It identifies the circumstances under which knowledge codification takes place in the long run and studies its effects on long run economic development.

R&D-Based Growth in the Post-Modern Era. [PDF]

open access: yes
Conventional R&D-based growth theory suggests that productivity growth is positively correlated with population size or population growth, an implication which is hard to see in the data.

Public education, technological change and economic prosperity: semi-endogenous growth revisited [PDF]

open access: yes, 2012
We introduce publicly funded education into R&D based economic growth theory. Our framework allows us to i) explicitly describe a realistic process of human capital accumulation within these types of growth models, ii) reconcile semi-endogenous growth ...

Biomimetic Fibrinogen Nanofiber Scaffolds for Vascular Hematopoietic Stem Cell Niche Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents an advanced in vitro model of the vascular hematopoietic stem cell niche using self‐assembled fibrinogen nanofibers, mimicking the basement membrane in bone marrow (BM) sinusoids. The model supports the coculture of microvascular endothelial cells, stromal cells, and hematopoietic stem and progenitor cells, providing insights into ...

Public Inputs and Productivty in the Agricultural Sector: A Dynamic Dual Approach [PDF]

open access: yes
This paper introduces a dynamic model of productivity measurement based on recent endogenous growth theories. The model presented in this study is based on dynamic duality theory and incorporate public goods (public capital and R&D) as external factors ...
