In series double quantum dot with finite bias, strong current suppression by spinselection rule is expected. Before the current becomes zero starting from a certain initial condition, the transient current flows through the system. We theoretically argue this excess current, under which condition, becomes a simple fraction of charge quantum after being integrated in time. We also propose a sche...

this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...

The gate current of MOS tunneling diodes biased at inversion region with different substrate doping is investigated. For p-type substrate (1–5 -cm) devices, the tunneling diode works in the deep depletion region and the inversion current is dominated by the thermal generation rate of minority electrons via traps at Si/SiO2 interface and in the deep depletion region. The activation energy is app...

Upside-down inversion disrupts the processing of spatial relations between the features of a face, while largely preserving local feature analysis. However, recent studies on face inversion failed to observe a clear dissociation between relational and featural processing. To resolve these discrepancies and clarify how inversion affects face perception, the authors monitored inversion effects se...

We present a method for obtaining atmospheric temperature, pressure, and number density profiles for small bodies through inversion of light curves recorded during stellar occultations. This method avoids the assumption that the atmospheric scale height is small compared with the radius of the body, and it includes the variation of gravitational acceleration with radius. First we derive the int...

The problem of microwave tomography consists of finding the electrical characteristics (permittivity and conductivity) of a medium using scattered fields measured under various conditions of illumination. Such inversion can be achieved with a variety of techniques based upon the minimization of an appropriate criterion. The popular current source inversion (CSI) technique is one of those. In th...

This paper discusses the evolution of subject-verb inversion in declarative root clauses in French. The frequent occurrence of such constructions in Medieval French is generally accounted for in terms of a V2 analysis, and their marginality in Modern (Standard) French is attributed to the loss ofV2. Given clear evidence against the assumed V2 status of Medieval French, subject-verb inversion is...
