      Volatiles are compounds with low sublimation temperatures, and they make up most of the condensible mass in typical planet-forming environments. They consist of relatively small, often hydrogenated, molecules based on the ...
    • Volatility and Growth: Credit Constraints and Productivity-Enhancing Investment 

      Aghion, Philippe; Angeletos, George-Marios; Banerjee, Abhijit; Manova, Kalina (2005)
      We examine how credit constraints affect the cyclical behavior of productivity-enhancing investment and thereby volatility and growth. We first develop a simple growth model where firms engage in two types of investment: ...
    • Volatility and growth: Credit constraints and the composition of investment 

      Aghion, Philippe; Angeletos, George-Marios; Banerjee, Abhijit; Manova, Kalina (Elsevier BV, 2010)
      This paper examines how uncertainty and credit constraints affect the cyclical composition of investment and thereby volatility and growth. We develop a model where firms engage in two types of investment: a short-term one; ...
    • Volatility, Labor Market Flexibility, and the Pattern of Comparative Advantage 

      Cuñat, Alejandro; Melitz, Marc J. (Wiley Blackwell (Blackwell Publishing), 2012)
      This paper studies the link between volatility, labor market flexibility, and international trade. International differences in labor market regulations affect how firms can adjust to idiosyncratic shocks. These institutional ...
    • Volcanic Glasses at the Izu Arc Volcanic Front: New Perspectives on Fluid and Sediment Melt Recycling in Subduction Zones 

      Straub, S.M; Layne, G.D.; Schmidt, A.; Langmuir, Charles (American Geophysical Union, 2004)
      Volcanic glasses contained in distal fallout tephras from the Izu arc volcanic front (Izu VF) provide unique perspectives on general problems of arc volcanism. Unlike cogenetic lavas, these glasses are liquid compositions ...
    • Volcanogenic Chlorofluorocarbons and the Recent CFC Anomalies 

      Klobas, J. Eric; Wilmouth, David (2019-05-15)
      This document is a white paper prepared at the request of the Scientific Assessment Panel (SAP) of the Montreal Protocol. We briefly review the literature regarding the volcanogenic production of chlorofluorocarbons within ...
    • Voltage imaging and optogenetics reveal behaviour-dependent changes in hippocampal dynamics 

      Adam, Yoav; Kim, Jeong J.; Lou, Shan; Zhao, Yongxin; Xie, Michael E.; Brinks, Daan; Wu, Hao; Mostajo-Radji, Mohammed A.; Kheifets, Simon; Parot, Vicente; Chettih, Selmaan; Williams, Katherine J.; Gmeiner, Benjamin; Farhi, Samouil L.; Madisen, Linda; Buchanan, E. Kelly; Kinsella, Ian; Zhou, Ding; Paninski, Liam; Harvey, Christopher D.; Zeng, Hongkui; Arlotta, Paola; Campbell, Robert E.; Cohen, Adam (Springer Science and Business Media LLC, 2019-05)
      A technology to record membrane potential from multiple neurons, simultaneously, in behaving animals will have a transformative impact on neuroscience research1, 2. Genetically encoded voltage indicators are a promising ...
    • Voltage Noise in Production Processors 

      Janapa Reddi, Vijay; Kanev, Svilen; Kim, Wonyoung; Campanoni, Simone; Smith, Michael D.; Wei, Gu-Yeon; Brooks, David M. (Institute of Electrical & Electronics Engineers (IEEE), 2011)
      Voltage variations are a major challenge in processor design. Here, researchers characterize the voltage noise characteristics of programs as they run to completion on a production Core 2 Duo processor. Furthermore, they ...
    • Voltage Smoothing: Characterizing and Mitigating Voltage Noise in Production Processors via Software-Guided Thread Scheduling 

      Reddi, Vijay Janapa; Kanev, Svilen; Kim, Wonyoung; Campanoni, Simone; Smith, Michael D.; Wei, Gu-Yeon; Brooks, David M. (IEEE, 2010)
      Parameter variations have become a dominant challenge in microprocessor design. Voltage variation is especially daunting because it happens so rapidly. We measure and characterize voltage variation in a running Intel Core2 ...
    • Voltage-Driven DNA Translocations through a Nanopore 

      Meller, Amit; Nivon, Lucas; Branton, Daniel (American Physical Society, 2001)
      We measure current blockade and time distributions for single-stranded DNA polymers during voltage-driven translocations through a single α-hemolysin pore. We use these data to determine the velocity of the polymers in the ...
    • Voltaire, Historian 

      Darnton, Robert (Rutgers, 2015)
    • Volume MLS Ray Casting 

      Ledergerber, Christian; Guennebaud, Gael; Meyer, Miriah D; Bacher, Moritz; Pfister, Hanspeter (Institute of Electrical and Electronics Engineers, 2008)
      The method of Moving Least Squares (MLS) is a popular framework for reconstructing continuous functions from scattered data due to its rich mathematical properties and well-understood theoretical foundations. This paper ...
    • The VolumePro Real-Time Ray-Casting System 

      Pfister, Hanspeter; Hardenbergh, Jan; Knittel, Jim; Lauer, Hugh; Seiler, Larry (Association for Computing Machinery, 1999)
      This paper describes VolumePro, the world’s first single-chip realtime volume rendering system for consumer PCs. VolumePro implements ray-casting with parallel slice-by-slice processing. Our discussion of the architecture ...
    • The von Kries hypothesis and a basis for color constancy 

      Chong, Hamilton; Gortler, Steven; Zickler, Todd (Institute of Electrical and Electronics Engineers (IEEE), 2007)
      Color constancy is almost exclusively modeled with diagonal transforms. However, the choice of basis under which diagonal transforms are taken is traditionally ad hoc. Attempts to remedy the situation have been hindered ...

    • Vortex Molecules in Spinor Condensates 

      Turner, Ari M.; Demler, Eugene A. (American Physical Society, 2009)
      Condensates of atoms with spins can have vortices of several types; these are related to the symmetry group of the atoms’ ground state. We discuss how, when a condensate is placed in a small magnetic field that breaks the ...
    • Vortex-Peierls States in Optical Lattices 

      Burkov, A. A.; Demler, Eugene A. (American Physical Society (APS), 2006)
      We show that vortices, induced in cold atom superfluids in optical lattices, may order in a novel vortexPeierls ground state. In such a state vortices do not form a simple lattice but arrange themselves in clusters, within ...
