Th e rapid economic rise of China, India, and the Association of Southeast Asian Nations (ASEAN) could have several eff ects on regional peace and global security. Th e power transition perspective overstates the risk of confl ict that results from convergence between dominant and challenger states. Rapid changes in economic and military capabilities can, however, have negative consequences for...

This experimental study aims to extend the know-how on biomechanical performances of duplex stainless steel (DSS) for tissue engineering applications a graded lattice geometry scaffold based F53 DSS (UNS S32750 according ASTM A182) produced by laser powder bed fusion (LPBF). The same dense-out rhombic dodecahedral elementary unit cells investigated in previous work 316L (SS) was adopted here ma...

We report results of measurements and theoretical modeling of spontaneous spin polarization and associated hysteresis in an optically pumped Cs vapor. We observe hysteresis over the full range ~20–450 torr! of N2 buffer gas pressures tested, and on two hyperfine components of the D1 transition, so long as both electronic spin exchange and optical pumping of a resolved ground state hyperfine lev...

A strain of a novel mucoralean fungus was isolated from a nest of the invasive paper wasp, Polistes dominulus. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and 5.8S rRNA gene sequences, along with physiological tests, revealed that this strain represents a novel species within the genus Mucor. The novel species also includes a representative that had previously b...

Aim—To study the eVect of enteral feeding on splanchnic blood flow velocity in preterm infants. Method—Coeliac axis and superior mesenteric artery (SMA) blood flow velocity were measured longitudinally in a cohort of 61 babies using Doppler ultrasound. Results—Babies fed 1 hourly had significantly higher preprandial SMA peak systolic velocity (PSV) than those fed 3 hourly (70 vs 53 cm/s). Those...

This paper formulates a dynamic model of global carbon consumption in the absence of an effective international agreement. Each period, countries extract carbon from the global ecosystem. A country’s output depends both on its carbon usage and on“stored carbon” in the ecosystem. We characterize Business-as-usual (BAU) equilibria as smooth, Markov Perfect equilibrium profiles of carbon usage acr...

I provide a novel dynamic model with private provision of public bads and investments in technologies. The analysis is tractable and the MPE unique. By adding incomplete contracts, I derive implications of and for international climate treaties. While the non-cooperative equilibrium is bad, short-term agreements are worse due to hold-up problems. A long-term agreement should be more ambitious i...

Exploiting the historical variations in the structure of the international co ee bean market, I separately identify the e ects of an international cartel agreement and the emergence of a fringe exporting country on the market power and the commodity's price. The results suggest that, of the 75-percent drop in the real co ee price between 1988 and 2001, the cartel's breakdown explains 49 points ...

The objective of this study was to evaluate the effect of human gut-derived lactic acid bacteria and bifidobacteria on cholesterol levels in vitro. Continuous cultures inoculated with fecal material from healthy human volunteers with media supplemented with cholesterol and bile acids were used to enrich for potential cholesterol assimilators among the indigenous bacterial populations. Seven pot...
