One-dimensional band-edge absorption in a doped quantum wire.
Low-temperature photoluminescence-excitation spectra are studied in an n-type modulation-doped T-shaped single quantum wire with a gate to tune electron densities. With a nondegenerate one-dimensional (1D) electron gas, the band-edge absorption exhibits a sharp peak structure induced by the 1D density of states. When the dense 1D electron gas is degenerate at a low temperature, we observe a Fer...
متن کاملMeiotic Spindle Self-Organization: One Plus One Equals Only One
Like other cellular organelles, the bipolar spindle is a structure of well-defined size and shape. Now, spindle fusion experiments using micro-manipulation have allowed current models for spindle morphogenesis and size control to be tested.
متن کاملA one-horse race can have only one winner.
TO THE EDITOR: The spectrum of reactions to my Viewpoint (3) regarding the role of the airway smooth muscle (ASM) in creating airway hyperresponsiveness akin to asthma has raised several interesting points (see Ref. 4). First, I must begin with a critical clarification. A few of the responders appear under the impression that I suggested the ASM was the “horse” we should dismount or stop chasin...

This linkage increases their resistance to accepting such caps. Also, the profitability of offsets motivates developing countries to insist on stricter...
متن کاملA Queueing-Inventory System with Repair Center for Defective Items and One-for-One Ordering Policy
In this paper we consider a system consisting of a supplier with a single processing unit, a repair center, and a retailer with Poisson demand. We assume that the retailer applies one-for-one ordering policy with backorders for his inventory control. The retailer’s orders form a queue in the supplier processing unit. We also assume that a certain fraction of the products produced by the supplie...
