A low H I column density filament in NGC 2403 : signature of interaction or accretion
(2014-09-25)Observed H i accretion around nearby galaxies can only account for a fraction of the gas supply needed to sustain the currently observed star formation rates. It is possible that additional accretion occurs in the form of ... -
Low hygroscopic scattering enhancement of boreal aerosol and the implications for a columnar optical closure study
(2015-07-02)Ambient aerosol particles can take up water and thus change their optical properties depending on the hygroscopicity and the relative humidity (RH) of the surrounding air. Knowledge of the hygroscopicity effect is of crucial ... -
Low noise, low distortion, high frequency, fully differential CMOS transconductor
(Institute of Electrical and Electronics Engineers (IEEE), 2000)This paper describes a CMOS transconductance element based upon two differential pairs whose outputs are summed to give a linear transfer characteristic. The circuit has been simulated using a 2 μm process from MOSIS, and ... -
Low pH up‐regulates interleukin‐6 mRNA in L6‐G8C5 rat skeletal muscle cells independent of pH sensing by SNAT2(SLC38A2) transporters
(2021-11-09)Exercise is known to create a transient, but potent increase in skeletal muscle expression of potentially anti‐inflammatory myokine interleukin‐6 (IL‐6). This effect may be clinically important in managing chronic inflammatory ... -
Low Polarization Standards
(Astronomical Society of the Pacific, 2007)There is renewed interest in high sensitivity polarimetry as a means of observing the polarization signal of extra-solar planets. We describe the measurement of low polarized standards at fractional polarizations of parts ... -
Low Radio Frequency Observations and Spectral Modelling of the Remnant of Supernova 1987A
(2016-10-11)We present Murchison Widefield Array observations of the supernova remnant (SNR) 1987A between 72 and 230 MHz, representing the lowest frequency observations of the source to date. This large lever arm in frequency space ... -
Low serum osteoprotegerin levels in normoalbuminuric type 1 diabetes mellitus
(2010)The aim of this study is to establish whether abnormal mineral metabolism is present in patients with type 1 DM with normal renal function and in the absence of microalbuminuria. Serum levels of 1,25-dihydroxyvitamin D, ... -
A low upper mass limit for the central black hole in the late-type galaxy NGC 4414
(2017-01-01)We present our mass estimate of the central black hole in the isolated spiral galaxy NGC 4414. Using natural guide star adaptive optics assisted observations with the Gemini Near-Infrared Integral Field Spectrometer (NIFS) ... -
Low velocity heavy mass impact response of single curve composites
(2014-01)This article presents an extensive experimental investigation of singly curved fibre-reinforced composite structures subjected to low energy heavy mass impact. The objective of the study is to understand the contribution ... -
Low Velocity Impact Response of Composite Panels for Aeronautical Applications
(Newswood Limited, 2015)The present experimental work analyses the impact behaviour of thermosetting composite materials for aeronautic applications. The main goal of the experimental activity was to identify the energy level in correspondence ... -
Low-Complexity Energy Efficiency Optimization with Statistical CSI in Two-Hop MIMO Systems
(2014-11-30)Energy-efficient resource allocation in a single-user, amplify-and-forward (AF), relay-assisted, multiple-input-multiple-output (MIMO) system is considered in this paper. Previous results in this area assume that perfect ... -
Low-Complexity Lattice Reduction Aided Schnorr Euchner Sphere Decoder Detection Schemes with MMSE and SIC Pre-processing for MIMO Wireless Communication Systems
(IEEE Computer Society, 2022-03-03)The LRAD-MMSE-SIC-SE-SD (Lattice Reduction Aided Detection - Minimum Mean Squared Error-Successive Interference Cancellation - Schnorr Euchner - Sphere Decoder) detection scheme that introduces a trade-off between performance ... -
Low-Cost and High-Reduction Approaches for Power Droop during Launch-On-Shift Scan-Based Logic BIST
(2016-08-31)During at-speed test of high performance sequential ICs using scan-based Logic BIST, the IC activity factor (AF) induced by the applied test vectors is significantly higher than that experienced during its in field operation. ... -
Low-cost credit card-based microfluidic devices for magnetic bead immobilisation
(2013-01)We report a simple low-cost magnetic microfluidic device for magnetic bead separation and immobilisation. One dimensional arrays of localised high magnetic field gradients are constructed at the interfaces between regions ... -
Low-cost MIMO-RoF-PON architecture for next-generation integrated wired and wireless access networks
(2021-03-01)Next-generation integrated fiber-wireless access networks will require low-cost and high-capacity deployment to meet customer demand. A new configuration of radio over fiber--passive optical network (RoF-PON) architecture, ...
