Brane-world models, where observers are restricted to a brane in a higher dimensional spacetime, offer a novel perspective on cosmology. I discuss some approaches to cosmology in extra dimensions and some interesting aspects of gravity and cosmology in brane-world models. COSMOLOGY AFTER EINSTEIN A century after Einstein first proposed his theory of relativity, it has become a cornerstone of th...

Symptom exaggeration or fabrication occurs in a sizeable minority of neuropsychological examinees, with greater prevalence in forensic contexts. Adequate assessment of response validity is essential in order to maximize confidence in the results of neurocognitive and personality measures and in the diagnoses and recommendations that are based on the results. Symptom validity assessment may incl...

This paper analyzes changes in concentration levels in the U.S. Advertising and Marketing Services (A&MS) industry using publicly released data that have been largely ignored in past discussions of the industrial organization of this industry, namely those available from the U.S. Census Bureau’s quinquennial Economic Census and the Service Annual Survey. We define the A&MS industry in terms of ...

The purpose of this paper is to determine the large N asymptotics of the free energy FN (a, U |A) of Y M2 (two-dimensional Yang Mills theory) with gauge group GN = SU(N) on a cylinder where a is a so-called principal element of type ρ. Mathematically, FN (U1, U2|A) = 1 N2 log HGN (A/2N, U1, U2) is the central heat kernel of GN . We find that FN (aN , UN |A) ∼ N A Ξ(dθ, dσ) where Ξ is an explici...

This paper proposed a method for assembly sequence planning for modular product. Community structure were used in assembly sequence. Firstly, GN Algorithm was employed to detecting the module of product, Secondly candidate sets of disassembly sequence can be generated according to the module partition evolution process and priority rules, Lastly, the optimization of disassembly sequence could b...

A parallel corpus of texts in English and in Inuktitut, an Inuit language, is presented. These texts are from the Nunavut Hansards. The parallel texts are processed in two phases, the sentence alignment phase and the word correspondence phase. Our sentence alignment technique achieves a precision of 91.4% and a recall of 92.3%. Our word correspondence technique is aimed at providing the broades...

E conomists have long puzzled over the astounding differences in productivity between fi rms and countries. For example, looking at disaggregated data on U.S. manufacturing industries, Syverson (2004a) found that plants at the 90 percentile produced four times as much as the plant in the 10 percentile on a per-employee basis. Only half of this difference in labor productivity could be accounted...

In this paper we seek to understand the relationship between the online popularity of an article and its intrinsic quality. Prior experimental work suggests that the relationship between quality and popularity can be very distorted due to factors like social influence bias and inequality in visibility. We conduct a study of popularity on two different social news aggregators, Reddit and Hacker ...

Facebook, with over 800 million active users, is one of the most successful social networking sites. It offers the quick exchange of data among geographically dispersed users to help them build and maintain social relationships. However, with the recent changes to its News Feed, Facebook has inundated users with information. Many users are bewildered and are unable to filter out irrelevant info...

The neighborhood overlap (NOVER) of an edge u-v is defined as the ratio of the number of nodes who are neighbors for both u and v to that of the number of nodes who are neighbors of at least u or v. In this paper, we hypothesize that an edge u-v with a lower NOVER score bridges two or more sets of vertices, with very few edges (other than u-v) connecting vertices from one set to another set. Ac...
