Direct Suppression as a Mechanism for Controlling Unpleasant Memories in Daily Life
(American Psychological Association, 2014)Suppressing unwanted memories can impair their later recall. Recent work shows that this forgetting is achieved by at least two mechanisms supported by distinct neural systems: thought substitution and direct suppression ... -
Direct top-quark decay width measurement in the t t ̄ lepton+jets channel at √s = 8 TeV with the ATLAS experiment
(Springer Science and Business Media LLC, 2018-02)This paper presents a direct measurement of the decay width of the top quark using tt ̄ events in the lepton+jets final state. The data sample was collected by the ATLAS detector at the LHC in proton–proton collisions at ... -
Direct Transformation of 2,3-Epoxy Alcohols into Hydroxy Carbonates Under Mildly Basic Conditions
(Elsevier, 1988)2,3-Epoxy alcohols are transformed into the corresponding C2-inverted hydroxy carbonates upon treatment with cesium carbonate-powdered 3-A molecular sieves in N,N-dimethylformamide under one atmosphere of carbon dioxide ... -
Direct Versus Indirect Remedies for Externalities
(University of Chicago Press, 1976)This paper is concerned with tax policies designed to obtain an improved competitive allocation in the presence of consumption externalities. It is known that the full optimum can, in general, be attained only through the ... -
Direct visualization of electrochemical reactions and comparison of commercial carbon papers in operando by fluorescence microscopy using a quinone-based flow cell
(The Electrochemical Society, 2017-07-07)We demonstrate the use of fluorescence microscopy as a tool for mapping the spatial distribution of fluid flow and electrochemical reactions in an operating aqueous quinone flow cell. 9,10- anthraquinone-2,7-disulfonic ... -
Direct visualization of quasi-ordered oxygen chain structures on Au(110)-(1×2)
(Elsevier BV, 2016)The Au(110) surface offers unique advantages for atomically-resolved model studies of catalytic oxidation processes on gold. We investigate the adsorption of oxygen on Au(110) using a combination of scanning tunneling ... -
Direct visualization of three-dimensional crystallization behavior in microgels
(American Physical Society, 2012)We use confocal microscopy to study the three-dimensional (3D) structure of colloidal crystals formed by poly(N-isopropylacrylamide)-co-(acrylic acid) microgels of diameter 1.0-1.5 mu m. The confocal images are tracked to ... -
Direct Writing and Actuation of Three-Dimensionally Patterned Hydrogel Pads on Micropillar Supports
(Wiley-Blackwell, 2011)Freely swelling, three-dimensionally patterned responsive hydrogels fabricated by multiphoton lithography on the tips of flexible pillars provide unique capabilities for the design of adaptive systems. The resulting materials ... -
Direct-Liquid-Evaporation Chemical Vapor Deposition of Nanocrystalline Cobalt Metal for Nanoscale Copper Interconnect Encapsulation
(American Chemical Society (ACS), 2017)In advanced microelectronics, precise design of liner and capping layers become critical, especially when it comes to the fabrication of Cu interconnects with dimensions lower than its mean free path. Herein, we demonstrate ... -
Direct-liquid-evaporation chemical vapor deposition of smooth, highly conformal cobalt and cobalt nitride thin films

Direct-Liquid-Injection Chemical Vapor Deposition of Nickel Nitride Films and Their Reduction to Nickel Films
(American Chemical Society, 2010)Smooth and continuous films of nickel nitride (NiNx) with excellent step coverage were deposited from a novel nickel amidinate precursor, Ni(MeC(NtBu)2)2, and either ammonia (NH3) or a mixture of NH3 and hydrogen (H2) gases ... -
Direct-to-Consumer Drug Advertisements Can Paradoxically Increase Intentions to Adopt Lifestyle Changes
(Frontiers Media S.A., 2016)Background: Direct-to-consumer (DTC) prescription drug advertisements are thought to induce “boomerang effects,” meaning they reduce the perceived effectiveness of a potential alternative option: non-pharmaceutical treatment ... -
Directed Altruism and Enforced Reciprocity in Social Networks
(MIT Press, 2009)We conduct online field experiments in large real-world social networks in order to decompose prosocial giving into three components: (1) baseline altruism toward randomly selected strangers, (2) directed altruism that ... -
Directed Evolution of a Small-Molecule-Triggered Intein with Improved Splicing Properties in Mammalian Cells
(Elsevier BV, 2011)Laboratory-created small-molecule-dependent inteins enable protein structure and function to be controlled post-translationally in living cells. Previously we evolved two inteins (2-4 and 3-2) that splice efficiently in ... -
Directed natural product biosynthesis gene cluster capture and expression in the model bacterium Bacillus subtilis
(Nature Publishing Group, 2015)Bacilli are ubiquitous low G+C environmental Gram-positive bacteria that produce a wide assortment of specialized small molecules. Although their natural product biosynthetic potential is high, robust molecular tools to ... -
Directed nucleation and growth by balancing local supersaturation and substrate/nucleus lattice mismatch
(Proceedings of the National Academy of Sciences, 2018)Controlling nucleation and growth is crucial in biological and artificial mineralization and self-assembly processes. The nucleation barrier is determined by the interfaces and local supersaturation. Although chemically ... -
Direction selectivity in the larval zebrafish tectum is mediated by asymmetric inhibition
(Frontiers Media S.A., 2012)The extraction of the direction of motion is an important computation performed by many sensory systems and in particular, the mechanism by which direction-selective retinal ganglion cells (DS-RGCs) in the retina acquire ... -
Directional Detection of Dark Matter With Diamond
(IOP Publishing, 2021-03-10)Searches for WIMP dark matter will in the near future be sensitive to solar neutrinos. Directional detection offers a method to reject solar neutrinos and improve WIMP searches, but reaching that sensitivity with existing ... -
Directional Differences in the Biaxial Material Properties of Fascia Lata and the Implications for Fascia Function
(Springer Science + Business Media, 2014)Fascia is a highly organized collagenous tissue that is ubiquitous in the body, but whose function is not well understood. Because fascia has a sheet-like structure attaching to muscles and bones at multiple sites, it is ... -
