• #### Low magnetic field transitions of rhenium near the critical temperature ﻿

(1972)
A cryostat was constructed using conventional and superconducting shielding techniques. The ambient magnetic field at the sample was reduced to less than 10 to the -5 Gauss. For the single crystal rhenium sample isothermal ...
• #### Low order bits of arithmetic unit, Rice University Computer Project ﻿

(1959)
In 1956, three Rice University faculty members, Zevi Salsburg, John Kilpatrick, and Larry Biedenharn, brought supercomputing to the school for the first time in the form of the R1 computer. While it wasn’t the first computer ...
• #### Low Power VLSI Architecture for Adaptive MAI Suppression in CDMA Using Multi-stage Convergence Masking Vector ﻿

(2005-09-01)
In this paper, we propose a novel low power and low complexity multi-stage Parallel-Residue-Compensation (PRC) architecture for enhanced MAI suppression in the CDMA systems. The accuracy of the interference cancellation ...
• #### Low Rank Estimation of Higher Order Statistics ﻿

(1995-12-01)
Low rank estimators for higher order statistics are considered in this paper. Rank reduction methods offer a general principle for trading estimator bias for reduced estimator variance. The bias-variance tradeoff is analyzed ...
• #### Low Resolution ab initio Phasing Method by Modification of Density and Phase in Real and Reciprocal Space ﻿

(2013-09-30)
Phasing problem in X-ray structure determination can be challenging. Several methods, such as Isomorphous Replacement and Molecule Replacement, are frequently used. But their success relies on the availability of either ...
• #### Low temperature vapor - liquid equilibrium. Ternary system: Methane - Ethane - Propane ﻿

(1953)
A vapor recycle type apparatus for obtaining vapor-liquid equilibrium data at low temperatures and high pressures was constructed. Its description and testing are presented. A method of analysis for light hydrocarbons using ...

• #### Low temperature vapor-liquid equilibrium in light hydrocarbon mixtures: Methane-ethane-propane system ﻿

(1957)
Experimental equilibrium data have been determined for 175 mixtures of methane, ethane, and propane. The investigation included temperatures from 50&deg;F to -200&deg;F and pressures up to the critical. A vapor recycle ...

• #### Low viscosity channels and the stability of long wavelength convection ﻿

(2010)
Mantle convection simulations with a low viscosity channel, akin to the Earth's asthenosphere, are characterized by long wavelength flow structure. Boundary layer theory predicts that as the viscosity of the channel ...
• #### Low wave speed zones in the crust beneath SE Tibet revealed by ambient noise adjoint tomography ﻿

(2014)
We present a refined 3D crustal model beneath SE Tibet from ambient noise adjoint tomography. Different from ray-theory-based tomography, adjoint tomography in this study incorporates a spectral-element method (SEM) and ...
• #### LOW-COMPLEXITY AND HIGH-PERFORMANCE SOFT MIMO DETECTION BASED ON DISTRIBUTED M-ALGORITHM THROUGH TRELLIS-DIAGRAM ﻿

(2010-03-01)
This paper presents a novel low-complexity multiple-input multipleoutput (MIMO) detection scheme using a distributed M-algorithm (DM) to achieve high performance soft MIMO detection. To reduce the searching complexity, ...
• #### Low-Energy Charge and Spin Dynamics in Quantum Confined Systems ﻿

(2012-09-05)
Condensed matter systems exhibit a variety of dynamical phenomena at low energy scales, from gigahertz (GHz) to terahertz (THz) frequencies in particular, arising from complex interplay between charge, spin, and lattice. ...
• #### Low-energy elastic scattering of oxygen atoms by atmospheric species ﻿

(1992)
This thesis reports measurements of absolute differential cross sections for elastic scattering of atomic oxygen at 0.5- and 1.5-keV laboratory energies. Measurements for targets of He, Ne, Ar, Kr, Xe, H$\sb2$, N$\sb2$, ...
• #### Low-energy gamma radiation from Cen. X-4 ﻿

(1972)
In July of 1969 a new X-ray source was detected in the southern sky near the constellation Centaurus. This source, identified as Centaurus X-4, displayed a variable intensity in the energy range 3 to 12 keV which at its ...
