Comparing dynamic causal models

open access: yesNeuroImage, 2004
This article describes the use of Bayes factors for comparing dynamic causal models (DCMs). DCMs are used to make inferences about effective connectivity from functional magnetic resonance imaging (fMRI) data. These inferences, however, are contingent upon assumptions about model structure, that is, the connectivity pattern between the regions included

A Low-Power High-Speed Dynamic Comparator With a Transconductance-Enhanced Latching Stage

open access: yesIEEE Access, 2019
Low-power, high-speed dynamic comparators are highly desirable in the design of high-speed analog-to-digital converters (ADC) and digital I/O circuits. Most dynamic comparators use a pair of cross-coupled inverters as the latching stage, which provides ...

Monolithic Si-Based AlGaN/GaN MIS-HEMTs Comparator and Its High Temperature Characteristics

open access: yesApplied Sciences, 2021
Monolithic GaN High Electron Mobility Transistor (HEMT)-integrated circuits are a promising application of wide band-gap materials. To date, most GaN-based devices behave as NMOS-like transistors. As only NMOS GaN HEMT is currently commercially available,

Technology and the dynamics of comparative advantage [PDF]

open access: yesReview of International Economics, 2017
AbstractThis paper explores how trade affects innovation in a two‐country, two‐good, two‐factor Heckscher–Ohlin model with heterogeneous firms. Trade openness induces an increase in process innovation in both industries. The increase is stronger in the comparative advantage industry. Trade openness boosts prospective entrants' profits in that industry,
