Interview with Peter Ward Fay

Interview in April 1997 with Peter Ward Fay, professor of history, emeritus, in the Division of Humanities and Social Sciences. Dr. Fay, an authority on India and China, received a BA from Harvard in 1947 and from Oxford in 1949. He received his PhD from Harvard in 1954 and joined the Caltech faculty as an assistant professor in 1955. He discusses growing up in Cambridge, Mass., in a musical family; both parents were pianists. Early education at Browne & Nichols [now Buckingham Browne & Nichols] and Deerfield. Matriculated at Harvard in 1941, where he joined ROTC; called up in June 1943; Officer Candidate School, second lieutenant in field artillery at Camp Gruber, Oklahoma. In February 1945, he was sent to the Italian front north of Florence, had six weeks of active service. He stayed in Italy for a year and then returned to Harvard as a senior, majoring in history. Rhodes scholar, 1947 to 1949, at Balliol College in Oxford; returned for a year of graduate work at Harvard, then spent a third year on the Rhodes Scholarship at Oxford, doing research on his PhD thesis on the rural constabulary. He was an instructor at Williams College 1951-1954 before joining the Humanities Division at Caltech. Recollections of the division chairman, Hallett Smith, his colleagues Alan Sweezy and David Elliot, and the humanities curriculum. He recalls the advent of social sciences, the friction within the division at the time, and the chairmanship of Robert Huttenback. Discusses the genesis of his research while at Williams; his interest in modern European history and in the Opium War; his visit to India, 1964-1966, resulting in publication of The Opium War 1840-1842 (1975, University of North Carolina Press; 1976, W. W. Norton). Recalls the research in India that produced The Forgotten Army: India's Armed Struggle for Independence 1942-1945 (1993, University of Michigan Press). Recalls his work on Caltech's Admissions Committee and his establishment of the "Introduction to Asia" course in Freshman humanities curriculum. Recruiting of historian/anthropologist Nicholas Dirks and the building up of Asian studies. Concludes by discussing the challenges in getting science students interested in history and his disapproval of the growing specialization in the Humanities and Social Sciences Division

World Measuring Living standards within cities

This report is divided into three main chapters. In this first chapter, we explore ‘the good, the bad, and the ugly’ of survey design for urban areas. The objective is to contribute to best practice and knowledge sharing on surveying urban areas through a frank discussion of successes and failures of the pilots, drawing particular attention to challenges associated with working in urban areas. The second chapter provides detailed information on the survey methodology. This section will act as a guide on the sampling strategy and weighting of the survey that is likely to be useful for analysts that work with data. The final chapter draws on descriptive statistics from the two pilot surveys to provide a first look at the kinds of insights that can be supported by this new survey instrument. Although this is only a preliminary analysis, the descriptive statistics provided in this chapter already demonstrate the advantages of looking at cities through a more focused lens. The chapter sheds new light on the challenges of access to basic services, informality, urban mobility, and housing in Dar es Salaam and Durban

The production of tt‾ , W+bb‾ and W+cc‾ is studied in the forward region of proton–proton collisions collected at a centre-of-mass energy of 8 TeV by the LHCb experiment, corresponding to an integrated luminosity of 1.98±0.02 fb−1 . The W bosons are reconstructed in the decays W→ℓν , where ℓ denotes muon or electron, while the b and c quarks are reconstructed as jets. All measured cross-sections are in agreement with next-to-leading-order Standard Model predictions.The production of $t\overline{t}$, $W+b\overline{b}$ and $W+c\overline{c}$ is studied in the forward region of proton-proton collisions collected at a centre-of-mass energy of 8 TeV by the LHCb experiment, corresponding to an integrated luminosity of 1.98 $\pm$ 0.02 \mbox{fb}^{-1}.

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV

Observation of the B0 → ρ0ρ0 decay from an amplitude analysis of B0 → (π+π−)(π+π−) decays

Proton–proton collision data recorded in 2011 and 2012 by the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb−1 , are analysed to search for the charmless B0→ρ0ρ0 decay. More than 600 B0→(π+π−)(π+π−) signal decays are selected and used to perform an amplitude analysis, under the assumption of no CP violation in the decay, from which the B0→ρ0ρ0 decay is observed for the first time with 7.1 standard deviations significance. The fraction of B0→ρ0ρ0 decays yielding a longitudinally polarised final state is measured to be fL=0.745−0.058+0.048(stat)±0.034(syst) . The B0→ρ0ρ0 branching fraction, using the B0→ϕK⁎(892)0 decay as reference, is also reported as B(B0→ρ0ρ0)=(0.94±0.17(stat)±0.09(syst)±0.06(BF))×10−6
