A Simple Model of Trade with Heterogeneous Firms and Trade Policy
This paper builds a Ricardian-Chamberlinian two-country model with heterogeneous firms in a monopolistically competitive sector in which every new entrant faces increasing fixed costs of production. There are efficiency gaps between countries in marginal and fixed costs and a country unilaterally imposes an import tariff. It is shown that an increase in tariff increases the number of firms of the tariff imposing country while decreases the number of firms of the tariff-imposed country, possibly reverting the position of net exporter of varieties. A tariff is detrimental to the tariff-imposed country. A small tariff may be beneficial to the tariff-imposing country.
Competing Communications Networks and International Trade
This paper investigates the effects of competing communication networks on trade patterns in a Chamberlinian-Ricardian model of monopolistically competitive firms with a continuum of industries that require communication services in production. We conclude that intraindustry trade between different networks is determined by the relative size of networks and technological differences, and that a network will not have an incentive to expand indefi- nitely, despite network externalities.
Quarkyonic Matter and Chiral Spirals
The nuclear matter, deconfined quark matter, and Quarkyonic matter in low
temperature region are classified based on the 1/Nc expansion. The chiral
symmetry in the Quarkyonic matter is investigated by taking into account
condensations of chiral particle-hole pairs. It is argued that the chiral
symmetry and parity are locally violated by the formation of chiral spirals, <
psibar exp(2 i mu z gamma^0 gamma^z) psi >. An extension to multiple chiral
spirals is also briefly discussed.Comment: Prepared for Hot Quark 2010, 4 page

On the Performance Evaluation of Action Recognition Models on Transcoded Low Quality Videos
In the design of action recognition models, the quality of videos in the
dataset is an important issue, however the trade-off between the quality and
performance is often ignored. In general, action recognition models are trained
and tested on high-quality videos, but in actual situations where action
recognition models are deployed, sometimes it might not be assumed that the
input videos are of high quality. In this study, we report qualitative
evaluations of action recognition models for the quality degradation associated
with transcoding by JPEG and H.264/AVC. Experimental results are shown for
evaluating the performance of pre-trained models on the transcoded validation
videos of Kinetics400. The models are also trained on the transcoded training
videos. From these results, we quantitatively show the degree of degradation of
the model performance with respect to the degradation of the video quality.Comment: 10 page
