International trade without CES : estimating translog gravity [PDF]
, 2012 This paper derives a micro-founded gravity equation based on a translog demand system that allows for flexible substitution patterns across goods. In contrast to the standard CES-based gravity equation, translog gravity generates an endogenous trade cost

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells
Advanced Materials Interfaces, EarlyView.Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.

Altered gravity modulates prostaglandin H synthase in human K562 cells
, 2000 In this study, we extended our previous observations on the effects of altered gravity on the "lipoxygenase pathway", by ascertain the possible role of the force of gravity in modulating the activity and expression of PHS in human erythro-leukemia K562 ...

Life‐Like Ferrous Oxide Microspheres from Kombucha
Advanced Materials Interfaces, EarlyView.Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

GOCE data evidence underplating beneath the Paraná basin
, 2012 The Paraná basin in the stable South American Platform accumulated a thick sediment layer during the Paleozoic, with more than 3500 m thickness. In Early Cretaceous the same area experienced a flood basalt volcanism which produced a LIP-(Large Igneous ...

Conformal Coating and Transfer of 2D Nanomaterials via Dynamic Interface Engineering
Advanced Materials Interfaces, EarlyView.This review discusses conformal coating and transfer of two‐dimensional (2D) nanomaterials with a focus on dynamic interface engineering. By actively regulating nanosheet transport and interfacial contact during film formation, recent dynamic coating strategies overcome the limitations of conventional passive approaches and enable geometry‐adaptive ...

Advanced Materials Technologies, EarlyView.High‐aspect‐ratio low‐melting‐point alloy inclusions are embedded within multilayer silicone laminates to create thermally programmable stiffness. Sequential activation of alloy‐rich layers produces four distinct mechanical states and reconfigures tendon‐driven actuator trajectories under the same load.

Angled Nozzle Aerosol Jet Printing to Streamline Conformal Patterning of Electronics
Advanced Materials Technologies, EarlyView.A modular, angled aerosol jet printhead is demonstrated to streamline patterning on nonplanar surfaces, including 90° step edges and confined internal geometries. A detailed analysis of gravitational settling for a sheathed aerosol flow and deconvolution of oblique deposition and gravitational effects supports the versatility of this approach for ...

Optokinetic Nystagmus under Prolonged Alteration in the Direction of Gravity.
Nippon Jibiinkoka Gakkai Kaiho, 1998 Optokinetic Nystagmus (OKN) exhibit different responses depending on the direction of gravity, with respect to head and body. In 13 normal healthy volunteers (10 experimental subjects and 3 controls), we studied the OKN evoked by horizontal and vertical stimuli, in upright, side-lateral, and repeated upright positions during a long time course of six ...
