One-step inactivation of chromosomal genes in <i>Escherichia coli</i> K-12 using PCR products
We have developed a simple and highly efficient method to disrupt chromosomal genes in Escherichia coli in which PCR primers provide the homology to the targeted gene(s). In thi...
Self-efficacy mechanism in human agency.
This article addresses the centrality of the self-efficacy mechanism in human agency. Self-per- cepts of efficacy influence thought patterns, actions, and emotional arousal. In ...
FLASH: fast length adjustment of short reads to improve genome assemblies
Abstract Motivation: Next-generation sequencing technologies generate very large numbers of short reads. Even with very deep genome coverage, short read lengths cause problems i...
Raman Spectrum of Graphene and Graphene Layers
Graphene is the two-dimensional building block for carbon allotropes of every other dimensionality. We show that its electronic structure is captured in its Raman spectrum that ...
The Strengths and Difficulties Questionnaire: A Research Note
A novel behavioural screening questionnaire, the Strengths and Difficulties Questionnaire (SDQ), was administered along with Rutter questionnaires to parents and teachers of 403...
Maps of Dust Infrared Emission for Use in Estimation of Reddening and Cosmic Microwave Background Radiation Foregrounds
We present a full-sky 100 μm map that is a reprocessed composite of the COBE/DIRBE and IRAS/ISSA maps, with the zodiacal foreground and confirmed point sources removed. Before u...
Harmonizing the Metabolic Syndrome
A cluster of risk factors for cardiovascular disease and type 2 diabetes mellitus, which occur together more often than by chance alone, have become known as the metabolic syndr...
PhysioBank, PhysioToolkit, and PhysioNet
Abstract —The newly inaugurated Research Resource for Complex Physiologic Signals, which was created under the auspices of the National Center for Research Resources of the Nati...
Finding and evaluating community structure in networks
We propose and study a set of algorithms for discovering community structure in networks-natural divisions of network nodes into densely connected subgroups. Our algorithms all ...
Social Cognitive Theory: An Agentic Perspective
▪ Abstract The capacity to exercise control over the nature and quality of one's life is the essence of humanness. Human agency is characterized by a number of core features tha...
