A Search for ttˉt\bar{t} Resonances in Lepton Plus Jets Events with ATLAS using 14 fb−1^{-1} of Proton-Proton Collisions at s\sqrt{s} = 8 TeV

Some Beyond the Standard Model theories predict new particles that decay predominantly into top-antitop quark pairs. A search for top-antitop quark resonances that decay into the lepton plus jets final state is carried out with the ATLAS experiment at the LHC using 14 fb$^{-1}$ of $\sqrt{s}$ = 8 TeV proton-proton collisions. The search considers both cases where all of the final state jets are isolated and where some or all of the top quark decay products are merged into a single jet. Mass exclusion limits at a 95% credibility level are set for two benchmark models, one predicting leptophobic topcolor Z' bosons and the other predicting Randall-Sundrum Kaluza-Klein gluons.Comment: Presentation at the DPF 2013 Meeting of the American Physical Society Division of Particles and Fields, Santa Cruz, California, August 13-17, 201

A Qualitative Study on the Social Impact of Industrialisation in Badli

The article aims to investigate and analyze the social impact of industrialization on Badli. Badli is one of the largest industrial zones in Delhi which also bears large slums neighboring to the industries. The literature available on the area is also limited to news articles and government reports, thus further research on Badli is required. The social implications were examined through naturalistic observational research and unstructured interviews of 10 individuals from Badli. Using thematic analysis and secondary data analysis the data was interpreted into common themes and key ideas. The analysis showed most Industries in Badli are unauthorized and have issues such as unemployment, child labor, hazardous working conditions, nominal wages, producing illegal substances and lack of healthcare management. People living in the neighboring slum areas suffer from issues such as poor health care facilities, below par educational infrastructure, high crime rates, harmful drainage and ventilation services, congested housing structures, economic disparity, and toxic family environment. Thus Industrialization has deeper implications on the society of Badli which can be attributed to the influx of migrants, industries and poor governance by the administrative authorities to control and manage the industrial process in Badli. It can be concluded that there is a huge correlation between social change and industrialization. Further studies are required to create socio-economic policies catering to the situation in Badli for a long-lasting sustainable effect on the area

China, India, Brazil and South Africa in the World Economy: Engines of Growth?

This paper attempts to analyse the economic implications of the rise of China, India, Brazil and South Africa, for developing countries situated in the wider context of the world economy. It examines the possible impact of their rapid growth on industrialized countries and developing countries, which could be complementary or competitive and, on balance, positive or negative. In doing so, it considers the main channels of transmission, to focus on international trade, investment, finance and migration. The essential question is whether, in times to come, these four countries could be the new engines of growth for the world economy. The answer is that rapid growth in China already supports growth elsewhere, so far primarily as a market for exports, while India and Brazil have the potential to provide similar support, but South Africa does not yet exhibit such a potential. In future, these countries could also provide resources for investment and technologies for productivity. The transformation and catch-up could span half a century or longer. Even so, rapid growth in these large emerging economies is already beginning to change the balance of economic power in the world.China, India, Brazil, South Africa, growth, development, history, trade, investment, finance, migration

Optimal Mechanism Design with Flexible Consumers and Costly Supply

The problem of designing a profit-maximizing, Bayesian incentive compatible and individually rational mechanism with flexible consumers and costly heterogeneous supply is considered. In our setup, each consumer is associated with a flexibility set that describes the subset of goods the consumer is equally interested in. Each consumer wants to consume one good from its flexibility set. The flexibility set of a consumer and the utility it gets from consuming a good from its flexibility set are its private information. We adopt the flexibility model of [1] and focus on the case of nested flexibility sets -- each consumer's flexibility set can be one of k nested sets. Examples of settings with this inherent nested structure are provided. On the supply side, we assume that the seller has an initial stock of free supply but it can purchase more goods for each of the nested sets at fixed exogenous prices. We characterize the allocation and purchase rules for a profit-maximizing, Bayesian incentive compatible and individually rational mechanism as the solution to an integer program. The optimal payment function is pinned down by the optimal allocation rule in the form of an integral equation. We show that the nestedness of flexibility sets can be exploited to obtain a simple description of the optimal allocations, purchases and payments in terms of thresholds that can be computed through a straightforward iterative procedure.Comment: 8 pages. arXiv admin note: text overlap with arXiv:1607.0252

Optimal Control for LQG Systems on Graphs---Part I: Structural Results

In this two-part paper, we identify a broad class of decentralized output-feedback LQG systems for which the optimal control strategies have a simple intuitive estimation structure and can be computed efficiently. Roughly, we consider the class of systems for which the coupling of dynamics among subsystems and the inter-controller communication is characterized by the same directed graph. Furthermore, this graph is assumed to be a multitree, that is, its transitive reduction can have at most one directed path connecting each pair of nodes. In this first part, we derive sufficient statistics that may be used to aggregate each controller's growing available information. Each controller must estimate the states of the subsystems that it affects (its descendants) as well as the subsystems that it observes (its ancestors). The optimal control action for a controller is a linear function of the estimate it computes as well as the estimates computed by all of its ancestors. Moreover, these state estimates may be updated recursively, much like a Kalman filter
