Flexible supercapacitors based on bendable electrodes have aroused much interest for integration in clothing materials and portable electronic devices. However, simultaneous achievement of high areal energy and high power densities still presents a great challenge. Herein we report the fabrication of free-standing, flexible graphene papers suitable for high-performance flexible supercapacitors....
The sensitivity of spatial analytic results to the way in which the areal units are defined is known as the modifiable areal unit problem (MAUP). Although to date a general solution to the problem does not yet exist, it has been suggested in the literature that the effects of the problem may be controllable within specific application contexts. The current study pursues this line of inquiry and...
recording areal densities to 100 Gb/in A. J. Argumedo D. Berman R. G. Biskeborn G. Cherubini R. D. Cideciyan E. Eleftheriou W. Häberle D. J. Hellman R. Hutchins W. Imaino J. Jelitto K. Judd P.-O. Jubert M. A. Lantz G. M. McClelland T. Mittelholzer C. Narayan S. Ölçer P. J. Seger We examine the issue of scaling magnetic tape-recording to higher areal densities, focusing on the challenges of achi...
As magmas rise toward the surface, they traverse regions of the mantle and crust with which they are not in equilibrium; to the extent that time and the intimacy of their physical contact permit, the melts and country rocks will interact chemically. We have modeled aspects of these chemical interactions in terms of ion-exchange processes similar to those operating in simple chromatographic colu...
Li R, Svenson KL, Donahue LR, Peters LL, Churchill GA. Relationships of dietary fat, body composition, and bone mineral density in inbred mouse strain panels. Physiol Genomics 33: 26–32, 2008. First published January 29, 2008; doi:10.1152/physiolgenomics.00174.2007.—Laboratory inbred mouse strains show a broad range of variation in phenotypes, such as body composition, bone mineral density (BMD...
This paper describes the areal density (bits per unit area) roadmap goals for tape based magnetic recording (TAPE) and uses these goals as counterpoints for the areal density roadmap strategies for Hard Disk Drive (HDD) and NAND flash. Technology comparisons described in this paper will show that presently volumetric densities (bits per unit volume) for TAPE, HDD, and NAND are similar and that ...
2 Existence of CMC and constant areal time foliations in T 2 symmetric spacetimes with Vlasov matter
The global structure of solutions of the Einstein equations coupled to the Vlasov equation is investigated in the presence of a twodimensional symmetry group. It is shown that there exist global CMC and areal time foliations. The proof is based on long-time existence theorems for the partial differential equations resulting from the EinsteinVlasov system when conformal or areal coordinates are ...
Inference for random processes depends on the estimation of the long-run variance of a statistic. Commonly used approaches in time series analysis for estimating the long-run variance include bootstrap approaches and the class of heteroskedasticity and autocorrelation consistent covariance estimators. These approaches have been generalized to deal with point processes and continuous spatial pro...
