Democratic Convergence and Free Trade [PDF]

open access: yesInternational Studies Quarterly, 1998
Even if a democracy were more likely to pursue free trade than an autocracy (an unproven generalization), the simultaneous spread of democracy in the world would not necessarily yield a reduction in protection, but might in fact cause an increase. The reason for this paradoxical outcome is the fact that democratic convergence creates power profiles ...

Artificial Modulation of the Hydrogen Evolution Reaction Kinetics via Control of Grain Boundaries Density in Mo2C Through Laser Processing

open access: yesAdvanced Functional Materials, EarlyView.
A laser‐driven strategy enables precise microstructural modulation of Mo₂C, achieving nanoscale grain control (15.6 ± 5 nm) and an ultrahigh grain boundary density (130 µm−1). Moreover, high‐angle grain boundaries enhance active sites, facilitate electron transport, and optimize hydrogen adsorption kinetics, significantly reducing overpotential.

All‐Cellulose‐Based Photonic Glitters

open access: yesAdvanced Functional Materials, EarlyView.
Uniform, disc‐shaped photonic CNC glitters with adjustable structural colors and diameters are fabricated on hydrophilic ethyl cellulose films using electrospray deposition. By employing patterned ethyl cellulose films with pre‐designed hydrophilic regions, photonic patterns can be created with these all‐cellulose‐based glitters, demonstrating their ...

An oligopolistic theory of regional trade agreements [PDF]

open access: yes, 2013
Why are trade agreements regional? I address this question in a model of oligopoly featuring product variety. Tarifs have the effect of manipulating a country's terms of trade and shifting profits towards the domestic market at the expense of foreign ...

Electricity Generation From Ambient Water Evaporation in the Absence of Sunlight via PVA‐Based Porous Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
In this article, a water‐evaporation driven energy harvester is devised that works even in the absence of sunlight. This is achieved by combining PVA hydrogel with thermoelectrics (TEG) to directly capture energy from water evaporation. Under mild conditions (RH 40%, T of 26 °C, and 2.8 m s−1 wind), 1.71 mW (1.02 W m−2) power can be generated, >3 fold ...

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

open access: yesAdvanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Mediterranean diet and dementia: MRI marker evidence from meta-analysis

open access: yesEuropean Journal of Medical Research
Background Dementia is a growing public health concern with limited effective treatments. Diet may be a modifiable factor that significantly impacts brain health. Mediterranean diet (MeDi) has been suggested to be associated with brain Magnetic Resonance

Interval of effective time-step size for the numerical computation of nonlinear ordinary differential equations

open access: yesAtmospheric and Oceanic Science Letters, 2017
The computational uncertainty principle states that the numerical computation of nonlinear ordinary differential equations (ODEs) should use appropriately sized time steps to obtain reliable solutions.
