Illusion and well-being: A social psychological perspective on mental health.
Many prominent theorists have argued that accurate perceptions of the self, the world, and the future are essential for mental health. Yet considerable research evidence suggest...
High-precision sampling for Brillouin-zone integration in metals
We present a sampling method for Brillouin-zone integration in metals which converges exponentially with the number of sampling points, without the loss of precision of normal b...
The Varimax Criterion for Analytic Rotation in Factor Analysis
An analytic criterion for rotation is defined. The scientific advantage of analytic criteria over subjective (graphical) rotational procedures is discussed. Carroll's criterion ...
Rapid and efficient site-specific mutagenesis without phenotypic selection.
Several single-base substitution mutations have been introduced into the lacZ alpha gene in cloning vector M13mp2, at 40-60% efficiency, in a rapid procedure requiring only tran...
Confidence Limits for the Indirect Effect: Distribution of the Product and Resampling Methods
The most commonly used method to test an indirect effect is to divide the estimate of the indirect effect by its standard error and compare the resulting z statistic with a crit...
Structural absorption by barbule microstructures of super black bird of paradise feathers
Abstract Many studies have shown how pigments and internal nanostructures generate color in nature. External surface structures can also influence appearance, such as by causing...
A biomarker that identifies senescent human cells in culture and in aging skin in vivo.
Normal somatic cells invariably enter a state of irreversibly arrested growth and altered function after a finite number of divisions. This process, termed replicative senescenc...
Alzheimer's Disease: The Amyloid Cascade Hypothesis
In both metazoan development and metastatic cancer, migrating cells must carry out a detailed, complex program of sensing cues, binding substrates, and moving their cytoskeleton...
