Central Dogma at the Single-Molecule Level in Living Cells
(Nature Publishing Group, 2011)Gene expression originates from individual DNA molecules within living cells. Like many single-molecule processes, gene expression and regulation are stochastic, that is, sporadic in time. This leads to heterogeneity in ... -
The Central Role of the Propensity Score in Observational Studies for Causal Effects
(Oxford University Press, 1983)The propensity score is the conditional probability of assignment to a particular treatment given a vector of observed covariates. Both large and small sample theory show that adjustment for the scalar propensity score is ... -
Centrality, rapidity, and transverse momentum dependence of isolated prompt photon production in lead-lead collisions at √ s N N = 2.76 TeV measured with the ATLAS detector

A century-long commitment to assessing artificial intelligence and its impact on society
(Association for Computing Machinery (ACM), 2018-11-20)In September 2016, Stanford's “One Hundred Year Study on Artificial Intelligence” project (AI100) issued the first report of its planned long-term periodic assessment of artificial intelligence (AI) and its impact on ... -
Cepheid Calibrations from the Hubble Space Telescopeof the Luminosity of Two Recent Type Ia Supernovae and a Redetermination of the Hubble Constant
(American Astronomical Society, 2005)We report observations of two nearby Type Ia supernovae (SNe Ia) for which observations of Cepheid variables in the host galaxies have been obtained with the Hubble Space Telescope: SN 1994ae in NGC 3370 and SN 1998aq in ... -
Certain Aspects of Cliticization in Polish
(Penn Graduate Linguistics Society, 1995)The main goal of this paper is to present an account of certain forms of cliticization in Polish. I will try to show that the fact that certain clitics undergo phonological processes typically assumed to be lexical does ... -
Certified Web Services in Ynot
(2010-04-21)In this paper we demonstrate that it is possible to implement certi ed web systems in a way not much di erent from writing Standard ML or Haskell code, including use of imperative features like pointers, les, and socket ... -
Ceteris Paribus Laws: Generics & Natural Kinds
(University of Michigan, 2010)Ceteris Paribus (cp-)laws may be said to hold only “other things equal,” signaling that their truth is compatible with a range of exceptions. This paper provides a new semantic account for some of the sentences used to ... -
César Vallejo: Dos Poemas Elegíacos
(El Colegio de Mexico, A.C., 1976-07-01)Los trabajos críticos sobre César Vallejo coinciden, en general, al es- tudiar el tema de la muerte en su poesía como uno de los temas capita- les y quizá el más constante entre los que se mantienen desde los He- raldos ... -
CfA3: 185 TYPE Ia SUPERNOVA LIGHT CURVES FROM THE CfA
(American Astronomical Society, 2009)We present multiband photometry of 185 type-Ia supernovae (SNe Ia), with over 11,500 observations. These were acquired between 2001 and 2008 at the F. L. Whipple Observatory of the Harvard-Smithsonian Center for Astrophysics ... -

CFT Duals for Extreme Black Holes
(Institute of Physics Publishing, 2009)It is argued that the general four-dimensional extremal Kerr-Newman-AdS-dS black hole is holographically dual to a (chiral half of a) two-dimensional CFT, generalizing an argument given recently for the special case of ... -
CFT's from Calabi–Yau four-folds
(Elsevier, 2000)We consider F/M/Type IIA theory compactified to four, three, or two dimensions on a Calabi-Yau four-fold, and study the behavior near an isolated singularity in the presence of appropriate fluxes and branes. We analyze the ... -
Chain Length Scaling of Protein Folding Time
(American Physical Society, 1996)Folding of protein-like heteropolymers into unique 3D structures is investigated using Monte Carlo simulations on a cubic lattice. We found that the folding time of chains of length N scales as N-lambda at the temperature ... -
Chain: A Dynamic Double Auction Framework for Matching Patient Agents
(AI Access Foundation, 2007)In this paper we present and evaluate a general framework for the design of truthful auctions for matching agents in a dynamic, two-sided market. A single commodity, such as a resource or a task, is bought and sold by ... -
The Chaine Operatoire Approach in Middle Paleolithic Archaeology
(University of Chicago Press, 2009)Since the pioneering days of Paleolithic archaeology in western Europe, the making of stone tools has received special attention. Numerous studies were aimed at creating systematic typologies of artifacts based on descriptions ... -

Chalcogen-hyperdoped germanium for short-wavelength infrared photodetection
(AIP Publishing, 2020-07-01)Obtaining short-wavelength-infrared (SWIR; 1.4 μm–3.0 μm) room-temperature photodetection in a low-cost, group IV semiconductor is desirable for numerous applications. We demonstrate a non-equilibrium method for hyperdoping ... -
The Challenge of Conflict of Interest in Medicine
(Elsevier, 2009)The expanding relationships between industry and medicine have produced great benefits. Industry support for medical research has led to important therapeutic breakthroughs. Such support has helped medical education at all ... -
The challenge of evolving stable polyploidy: could an increase in “crossover interference distance” play a central role?
(Springer Berlin Heidelberg, 2016)Whole genome duplication is a prominent feature of many highly evolved organisms, especially plants. When duplications occur within species, they yield genomes comprising multiple identical or very similar copies of each ...
