• #### 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 ...

• #### Low-frequency noise in spin valve sensors ﻿

(1999)
Low frequency noise in giant magnetoresistive spin valves has been studied as a means of optimizing signal to noise ratios and characterizing device performance. The devices studied were sputter deposited NiFe/Cu/NiFe/FeMn ...
• #### Low-Level Haskell Code: Measurements and Optimization Techniques ﻿

(2012-09-05)
Haskell is a lazy functional language with a strong static type system and excellent support for parallel programming. The language features of Haskell make it easier to write correct and maintainable programs, but ...
• #### Low-Loss Coupling of Quantum Cascade Lasers into Hollow-Core Waveguides with Single-Mode Output in the 3.7–7.6 μm Spectral Range ﻿

(2016)
We demonstrated low-loss and single-mode laser beam delivery through hollow-core waveguides (HCWs) operating in the 3.7–7.6 μm spectral range. The employed HCWs have a circular cross section with a bore diameter of 200 μm ...
• #### A LOW-POWER 1-Gbps RECONFIGURABLE LDPC DECODER DESIGN FOR MULTIPLE 4G WIRELESS STANDARDS ﻿

(2008-09-01)
In this paper we present an efficient system-on-chip implementation of a 1-Gbps LDPC decoder for 4G (or beyond 3G) wireless standards. The decoder has a scalable data path and can be dynamically reconfigured to support ...
• #### Lowe Supports Present Hierarchy Denies Inherent Conflict Charge ﻿

(1964-12-03)
• #### Lowe Will Succeed Savage as New Dean of Woman Next Fall ﻿

(1962-04-13)
• #### Lowell Liebermann: A stylistic analysis and discussion of the Sonata for Flute and Piano, op. 23, Sonata for Flute and Guitar, op. 25, and "Soliloquy" for flute solo, op. 44 ﻿

(1997)
The compositional style of three chamber works for flute by Lowell Liebermann is explored through harmonic and formal analyses, an interview with the composer, Lowell Liebermann, and interviews with the flutists who ...

(1977)
• #### A lower bound on snap-through instability of curved beams under thermomechanical loads ﻿

(2012)
A non-linear finite element formulation (three dimensional continuum elements) is implemented and used for modeling dynamic snap-through in beams with initial curvature. We identify a non-trivial (non-flat) configuration ...
• #### Lower Bounds on the Capacity of Gaussian Relay Channel ﻿

(2004-03-01)
It has been shown recently that the overall throughput of dense wireless networks can increase significantly when wireless nodes collaborate in transmission of different packets. In this paper, we focus on a simple network ...
• #### Lower health literacy predicts smoking relapse among racially/ethnically diverse smokers with low socioeconomic status ﻿

(2014)
Background: Nearly half of U.S. adults have difficulties with health literacy (HL), which is defined as the ability to adequately obtain, process, and understand basic health information. Lower HL is associated with negative ...
• #### Lower order solvability of links ﻿

(2013-09-16)
The n-solvable filtration of the link concordance group, defined by Cochran, Orr, and Teichner in 2003, is a tool for studying smooth knot and link concordance that yields important results in low-dimensional topology. We ...
