Reverse causality in global current accounts [PDF]

open access: yesSSRN Electronic Journal, 2010
The paper discusses global imbalances under the aspect of an asymmetric world monetary system. It identifies the US and Germany as center countries with rising / high current account deficits (US) and surpluses (Germany).

Reverse Schottky-Asymmetry Spin Current Detectors [PDF]

open access: yesApplied Physics Letters, 2010
By reversing the Schottky barrier-height asymmetry in hot-electron semiconductor-metal-semiconductor ballistic spin filtering spin detectors, we have achieved: 1.

Nonsinusoidal current and current reversals in a gating ratchet [PDF]

open access: yesPhysical Review E, 2015
In this work, the ratchet dynamics of Brownian particles driven by an external sinusoidal (harmonic) force is investigated. The gating ratchet effect is observed when another harmonic is used to modulate the spatially symmetric potential in which the particles move.

Current reversals and synchronization in coupled ratchets [PDF]

open access: yesPhysical Review E, 2010
Current reversal is an intriguing phenomenon that has been central to recent experimental and theoretical investigations of transport based on ratchet mechanism. By considering a system of two interacting ratchets, we demonstrate how the coupling can be used to control the reversals.

Simulated Impact of Shortened Strings in Commercial and Utility-Scale Photovoltaic Arrays

open access: yesEnergies, 2023
The deliberate removal of photovoltaic modules from a string can occur for various reasons encompassing maintenance, measurements, theft, or failure, reducing that string length relative to others when replacement modules are not available and there are ...

Investigation of the current density’s non-uniform distribution in dead-end PEMFC with multi-zone measurement methods

open access: yesEnergy Conversion and Management: X, 2023
Uneven current density distribution in a proton exchange membrane fuel cell (PEMFC) can decrease the reactant and catalyst utilization, reduce the energy conversion efficiency of the whole fuel cell, and even lead to a shortened cell life.

Current microfluidic platforms for reverse engineering of cornea

open access: yesMaterials Today Bio, 2023
According to the World Health Organization, corneal blindness constitutes 5.1% of global blindness population. Surgical outcomes have been improved significantly in the treatment of corneal blindness. However, corneal transplantation is limited by global

Tokamak Equilibria with Reversed Current Density [PDF]

open access: yesPhysical Review Letters, 2003
Observations of nearly zero toroidal current in the central region of tokamaks (the "current hole") raises the question of the existence of toroidal equilibria with very low or reversed current in the core. The solutions of the Grad-Shafranov equilibrium equation with hollow toroidal current density profile including negative current density in the ...

Tuning formation process of void defects in microcolumn arrays via pulse reverse electrodeposition

open access: yesJournal of Materials Research and Technology, 2023
The pulse reverse current electrodeposition process consists of two stages: the forward deposition and reverse dissolution. This study aims to understand the characteristics of forward deposition and reverse dissolution and to reveal their influences on ...
