Mutual funds approaching the IRS 50/5/10 portfolio concentration limit trim large positions, reduce equity exposure, and subsequently underperform.

Abstract: This article examines how electric current can arise from the random thermal motion of electrons and their concentration gradient, even in the absence of an applied electric field. Under ...

Abstract: Herein, concentration enrichment of sample solutes is obtained by using field-amplified sample stacking (FASS) in microchannel. Numerical investigations are performed to explored the effects ...

To use the code only an excel file is needed with the name "Connections.xlsx". This file has two sheets with the following names: "R" which stands for the resistors and "PQC" which contains the ...

Chemotaxis is a widespread mechanism that allows migrating cells to steer to where they are needed. Attractant gradients may be imposed by external sources, or self-generated, when cells create their ...

A central principle for understanding the cerebral cortex is that macroscale anatomy reflects a functional hierarchy from primary to transmodal processing. In contrast, the central axis of motor and ...

Growth cones navigate axonal projection in response to guidance cues. However, it is unclear how they can decide the migratory direction by transducing the local spatial cues into protrusive forces.

Here, we concentrate on one particularly useful equation that allows us to make changes to an analytical system to improve throughput or efficiency, while retaining the selectivity of the original ...

Cells navigate in response to inhomogeneous distributions of extracellular guidance cues. The cellular and molecular mechanisms underlying migration in response to gradients of chemical cues have been ...

Is it possible to get the same separation under isocratic and gradient conditions? In last month's "LC Troubleshooting" (1), we began our series of discussions on gradient elution. We saw that liquid ...

Circulating levels of microRNA (miR) have been proposed as biomarkers for cardiovascular disease. To identify the heart as a potential source for miRs released into the circulation, we measured ...
