The economics of infrastructure finance: Public-Private Partnerships versus public provision [PDF]

We examine the economics of infrastructure finance, focusing on public provision and Public-Private Partnerships (PPPs). We show that project finance is appropriate for PPP projects, because there are few economies of scope and because assets are project

Elevator‐Like Hollow Channels in Porous Scaffolds Accelerate Vascularized Bone Regeneration via NETs‐Fibrin‐Mediated Macrophage Recruitment

Advanced Science, EarlyView.
This study demonstrates that how hollow‐channel scaffolds promote vascularized bone regeneration via an immunomodulatory mechanism. The channel structures facilitate the formation of a neutrophil extracellular traps‐fibrin scaffold that recruits vascular endothelial growth factor A (VEGF‐A)‐secreting M2 macrophages to drive angiogenesis. Combining this

Synthesis and Characterization of Unusual S=1 Fe(0)‐Silyl Complexes Supported by Styrene Ligands

Angewandte Chemie, EarlyView.
Despite the long‐standing importance of iron‐silicon bonds as related to catalysis, high‐spin Fe(0)‐silyl complexes remain a historical synthetic challenge in the field. Herein, we report the first series of high‐spin S = 1, styrene‐stabilized Fe(0)‐silyl complexes followed by extensive characterization via Mössbauer spectroscopy, single crystal X‐ray ...

Confidence Intervals for Half-life Deviations from Purchasing Power Parity [PDF]

According to the Purchasing Power Parity (PPP) theory, real exchange rate fluctuations are mainly caused by transitory shocks. The theory fits well one empirical feature of the data, namely the short-run volatility of real exchange rates, but also ...

Ab initio calculation of the dynamical properties of PPP and PPV

, 2006
In this work, we have calculated the vibrational modes and frequencies of the crystalline PPP (in both the Pbam and Pnnm symmetries) and PPV (in the P21/c symmetry). Our results are in good agreement with the available experimental data.

Radical‐Mediated, Substrate‐Independent Fabrication of Hybrid Solid–Hydrogel Materials With Tunable Crosslinking: An Initiator‐ and Crosslinker‐Free Approach

Advanced Science, EarlyView.
This work introduces a substrate‐independent, reagent‐free plasma strategy that forms radical‐rich interlayers for covalent hydrogel attachment without initiators or crosslinkers. The long‐lived radicals drive in situ gelation, creating robust, cytocompatible hybrid solid–hydrogel constructs across diverse substrates.

Conversion of Transplanted Mature Hepatocytes into Afp+ Reprogrammed Cells for Liver Regeneration After Injury

Advanced Science, EarlyView.
Donor‐derived tdTomato+ mature hepatocytes were FACS‐isolated and transplanted into Fah−/− host mice. During regeneration, these cells convert into proliferative, unipotent Afp+ rHeps. Their plasticity is governed by a PPARγ/AFP‐dependent metabolic switch, segregating into pro‐proliferative Afplow and pro‐survival Afphigh subpopulations.

Purchasing Power Parity and Country Characteristics: Evidence from Time Series Analysis [PDF]

This paper investigates the relationships between country characteristics and the validity of PPP. We use three alternative time series methods to test for the stationarity of real exchange rates for each of the 72 countries over the period from 1976 to ...
