Holmium Oxide Glass Wavelength Standards
Holmium oxide glass has been used as a wavelength standard for over four decades. These standards have shown insignificant spectral variation from batch to batch and from one manufacturer to another. The National Institute of Standards and Technology (NIST) has certified and recertified holmium oxide glass samples for over four decades. Over this period of time there has been no recorded instan...

La coriorretinopatía central serosa (CRCS) está caracterizada por el acúmulo de fluido subretiniano que produce un levantamiento del neuroepitelio en el polo posterior. Es una patología que afecta a pacientes jóvenes, generalmente varones con personalidad tipo «A». En la mayoría de los casos se trata de un proceso autolimitado, que se resuelve en los primeros 3 meses. No obstante, existe una mi...
متن کاملTheory of commensurable magnetic structures in holmium.
The tendency for the period of the helically ordered moments in holmium to lock into values which are commensurable with the lattice is studied theoretically as a function of temperature and magnetic field. The commensurable effects are derived in the mean-field approximation from numerical calculations of the free energy of various commensurable structures, and the results are compared with th...
متن کاملCon guration Sequencing with Self Con gurable Binary Multipliers
In this paper we present a hardware design technique which utilises runtime recon guration for a particular class of applications. For a multiplication circuit implemented within an FPGA, a speci c instance of multiplying by a constant provides a signi cant reduction of required logic when compared to the generic case when multiplying any two arbitrary values. The use of recon guration allows t...
