Electroweak measurements from WW, ZZ and photon final states

We present the most recent precision electroweak measurements of single $W$ and $Z$ boson cross section and properties from the LHC and Tevatron colliders, analyzing data collected by ATLAS, CDF, CMS, D0, and LHCb detectors. The results include the measurement of the single $W$ and $Z$ boson cross section at LHC, the differential cross section measurements, the measurement of $W$ boson mass, the measurement of $W$ and $Z$ charge asymmetry. These measurements provide precision tests on the electroweak theory, high order predictions and the information can be used to constraint parton distribution functions.Comment: 14 pages, 16 figures, PIC201

L2L^2-index formula for proper cocompact group actions

We study the index of the $G$-invariant elliptic pseudo-differential operator acting on a complete Riemannian manifold, where a unimodular, locally compact group $G$ acts properly and cocompactly. An $L^2$-index formula was obtained using the heat kernel method.Comment: This is the final version (34 pages

The China Puzzle: Theory and Evidence on the Behavior of Chinese Exports during the 2008-2009 Global Financial Crisis

Many studies link the recent collapse in trade during the 2008-09 financial crisis to a decrease in the demand for durable and investment goods in crisis-hit countries. Thus, a remarkable feature of the recent collapse in international trade is that China’s export sectors – for which the crisis-hit U.S. and Europe are the primary destinations – appear much less affected than their counterparts in other exporting countries. This paper explains the puzzle by documenting a new stylized fact: China’s processing exports fell much less than ordinary trade during the 2008-09 financial crisis, even conditioning on industry and demand in the destination country. It then investigates a range of explanations for the special behavior of processing trade

A Methodological Reflection on Converging Technologies and Their Relevance to Informa-tion Ethics

In light of converging technologies, there is a clear sense that ethicists of various technological domains are coming together. Or, that they should come together. Yet, despite increasing cooperation and boundary-crossing in various fields of the ethics of technology, these efforts remain mostly at topical level. Relatively little attention has been given to issues on methodologies. The current paper aims to contribute to the current research by raising the methodological issues. In this paper, my objective is to argue that ethics of Information Technology (or Information Ethics (IE)) can benefit from the insights in other fields of the ethics of technology. Drawing the insights from other fields of the ethics of technology, I shall propose a systematic account of an Empirical Information Ethics (EIE)

What Should We Share? : Understanding the Aim of Intercultural Information Ethics

The aim of Intercultural Information Ethics (IIE), as Ess aptly puts, is to “(a) address both local and global issues evoked by ICTs / CMC, etc., (b) in a ways that both sustain local traditions / values / preference, etc. and (c) provide shared, (quasi-) universal responses to central ethical problems” (Ess 2007a, 102). This formulation of the aim of IIE, however, is not unambiguous. In this paper, I will discuss two different understandings of the aim of IIE, one of which advocates “shared norms, different interpretations” and another proposes “shared norms, different justifications”. I shall argue that the first understanding is untenable, and the second understanding is acceptable only with qualification. Finally, I shall briefly suggest an alternative way to understand the aim of IIE
