Crystalline monolayer surface of liquid Au–Cu–Si–Ag–Pd: Metallic glass former
(AIP Publishing, 2011)It is demonstrated by means of x-ray synchrotron reflectivity and diffraction that the surface of the liquid phase of the bulk metallic glass forming alloy Au_49 Cu_26.9 Si_16.3 Ag_5.5 Pd_2.3 consists of a two-dimensional ... -
Crystalline Phases of Alkyl-Thiol Monolayers on Liquid Mercury
(American Physical Society, 2005)The structure of octadecanethiol monolyers on liquid Hg surfaces, measured with subangstrom resolution, evolves with increasing coverage from a laterally disordered phase of surface-parallel molecules to ordered rotator ... -
Crystalline Surface Phases of the Liquid Au-Si Eutectic Alloy
(American Physical Society, 2007)A two-dimensional crystalline layer is found at the surface of the liquid eutectic Au82Si18 alloy above its melting point TM=359 °C. Underlying this crystalline layer, we find a layered structure, 6–7 atomic layers thick. ... -
Crystallinities and Light Emitting Properties of Nanostructured SiGe Alloy Prepared by Pulsed Laser Ablation in Inert Background Gases
(1999)For studying the material properties of nanostructured group IV materials, we have developed a pulsed laser ablation method into inert background gases. SiGe alloy nanocrystallites have the possibility of novel band structure ... -
Crystallization and reentrant melting of charged colloids in nonpolar solvents
(American Physical Society, 2015)We explore the crystallization of charged colloidal particles in a nonpolar solvent mixture. We simultaneously charge the particles and add counterions to the solution with aerosol-OT (AOT) reverse micelles. At low AOT ... -
CS50 Sandbox: Secure Execution of Untrusted Code
(Association for Computing Machinery, 2013)We introduce CS50 Sandbox, an environment for secure execution of untrusted code. Implemented as an asynchronous HTTP server, CS50 Sandbox offers clients the ability to execute programs (both interactive and non-interactive) ... -
Csm4, in Collaboration with Ndj1, Mediates Telomere-Led Chromosome Dynamics and Recombination during Yeast Meiosis
(Public Library of Science, 2008)Chromosome movements are a general feature of mid-prophase of meiosis. In budding yeast, meiotic chromosomes exhibit dynamic movements, led by nuclear envelope (NE)-associated telomeres, throughout the zygotene and pachytene ... -
Csnk1a1 inhibition has p53-dependent therapeutic efficacy in acute myeloid leukemia
(The Rockefeller University Press, 2014)Despite extensive insights into the underlying genetics and biology of acute myeloid leukemia (AML), overall survival remains poor and new therapies are needed. We found that casein kinase 1 α (Csnk1a1), a serine-threonine ... -
Ctip1 Controls Acquisition of Sensory Area Identity and Establishment of Sensory Input Fields in the Developing Neocortex
(Elsevier BV, 2016)While several transcriptional controls over the size and relative position of cortical areas have been identified, less is known about regulators that direct acquisition of area-specific characteristics. Here, we report ... -
Ctip1 Regulates the Balance between Specification of Distinct Projection Neuron Subtypes in Deep Cortical Layers
(Elsevier BV, 2016)The molecular linkage between neocortical projection neuron subtype and area development, which enables the establishment of functional areas by projection neuron populations appropriate for specific sensory and motor ... -
Ctip2 Controls the Differentiation of Medium Spiny Neurons and the Establishment of the Cellular Architecture of the Striatum
(Society for Neuroscience, 2008)Striatal medium spiny neurons (MSN) are critically involved in motor control, and their degeneration is a principal component of Huntington's disease. We find that the transcription factor Ctip2 (also known as Bcl11b) is ... -
Ctk1 Promotes Dissociation of Basal Transcription Factors from Elongating RNA Polymerase II
(Nature Publishing Group, 2009)As RNA polymerase II (RNApII) transitions from initiation to elongation, Mediator and the basal transcription factors TFIID, TFIIA, TFIIH, and TFIIE remain at the promoter as part of a scaffold complex, whereas TFIIB and ... -
Cuántica por Cuántica: Química Cuántica con Computadoras Cuánticas
(Facultad de Química de la Universidad Nacional Autónoma de México, 2008)Superposition and entanglement are properties of the quantum nature that suggest the construction, programming and functioning of quantum computers. Specifically, they have been imagined as a means for solving the Schrödinger ... -
Cube-3: A Real-Time Architecture for High-Resolution Volume Visualization
(Association for Computing Machinery, 1994)This paper describes a high-performance special-purpose system, Cube-3, for displaying and manipulating high- resolution volumetric datasets in real-time. A primary goal of Cube-3 is to render 512^3, 16-bit per ... -
Cube-4 - A Scalable Architecture for Real-Time Volume Rendering
(Association for Computing Machinery, 1996)We present Cube-4, a special-purpose volume rendering architecture that is capable of rendering high-resolution (e.g., 1024^3) datasets at 30 frames per second. The underlying algorithm, called slice-parallel ray-casting, ... -
Cubic curves and totally geodesic subvarieties of moduli space
(Annals of Mathematics, Princeton U, 2017)In this paper we present the first example of a primitive, totally geodesic subvariety F⊂g,nF⊂Mg,n with dim(F)>1dim(F)>1. The variety we consider is a surface F⊂1,3F⊂M1,3 defined using the projective geometry of plane ... -
Cucurto's Cardboard Coloring Book: Argentine Independence and Other Stories to Recycle
(2010)This article tries to prove how present historical and literary discourses are recyclable materials, as the framework of Argentina’s Bicentennial Independence official celebrations shows. The work done by Washington Cucurto ... -
Cue-Induced Dopamine Release Predicts Cocaine Preference: Positron Emission Tomography Studies in Freely Moving Rodents
(Society for Neuroscience, 2009)Positron emission tomography studies in drug-addicted patients have shown that exposure to drug-related cues increases striatal dopamine, which displaces binding of the D2 ligand, [11C]-raclopride. However, it is not known ... -
A Cue-Theory of Consumption
(MIT Press, 2000)Psychological experiments demonstrate that repeated pairings of a cue and a consumption good eventually create cue-based complementarities: the presence of the cue raises the marginal utility derived from consumption. In ... -
