A low-cost multi-channel aerosol fluorescence sensor for networked deployment.
(2004)We describe a low-cost prototype bio-aerosol fluorescence sensor designed for unattended deployment in medium to large area networks. The sensor uses two compact xenon flash units to excite fluorescence in an aerosol sample ... -
Low-Cost On-Chip Clock Jitter Measurement Scheme
(2015-03-01)In this paper, we present a low-cost, on-chip clock jitter digital measurement scheme for high performance microprocessors. It enables in situ jitter measurement during the test or debug phase. It provides very high ... -
Low-cost real-time multi-parameter bio-aerosol sensors (invited paper)
(2008-06-16)Sensors that are able to provide reagent-free, continuous monitoring for potential bio-aerosol hazards are required in many environments. In general, increasing the number of optical and spectroscopic properties of individual ... -
Low-Cost Wide-Angle Beam-Scanning Transmitarray Antennas Using Lens-Loaded Patch Elements: A Proof-of-Concept Study
(2023-08-23)In this letter, a novel design concept to achieve a low-cost wide-angle beam-scanning transmitarray (TA) using lens-loaded patch (LLP) elements is presented. In this design, each TA element consists of a beam switchable ... -
Low-Dose Aspirin for Primary Prevention of Cardiovascular Events Comparing East Asians With Westerners: A Meta-Analysis
(2023-09-12)Background East Asians have shown different risk profiles for both thrombophilia and bleeding than Western counterparts. Objectives The authors sought to evaluate the effect of low-dose aspirin for primary prevention between ... -
Low-dose electron image reconstruction of negatively stained contractile phage sheath from Bacillus subtilis (PBS-Z)
(1979)The structure of the contractile sheath of the defective phage from B. subtilis (PBS-Z) has been investigated by low-dose electron microscopy and image reconstruction. The extended and contracted sheath particles were ... -
The low-frequency environment of the Murchison Widefield Array : radio-frequency interference analysis and mitigation
(2015-01-16)The Murchison Widefield Array (MWA) is a new low-frequency interferometric radio telescope built in Western Australia at one of the locations of the future Square Kilometre Array (SKA). We describe the automated radio-frequency ... -
Low-frequency observations of the Giant Radio Galaxy NGC 6251
(2020-06-01)We present LOFAR observations at 150 MHz of the borderline FRI/FRII giant radio galaxy NGC 6251. This paper presents the most sensitive and highest-resolution images of NGC 6251 at these frequencies to date, revealing for ... -
Low-frequency radio absorption in Tycho's supernova remnant
(2019-12-02)Tycho's SNR is the remnant of the type Ia supernova explosion SN1572. In this work we present new low-frequency radio observations with the LOFAR Low-Band and High-Band Antennae, centred at 58 MHz and 143 MHz, and with an ... -
Low-frequency radio spectra of submillimetre galaxies in the Lockman Hole
(2021-04-19)We investigate the radio properties of a sample of 53 sources selected at 850 $\mu$m from the SCUBA-2 Cosmology Legacy Survey using new deep, low-frequency radio imaging of the Lockman Hole field from the Low Frequency ... -

Low-grade inflammation, diet composition and health : current research evidence and its translation
(2015-10-14)The importance of chronic low-grade inflammation in the pathology of numerous age-related chronic conditions is now clear. An unresolved inflammatory response is likely to be involved from the early stages of disease ... -
Low-Impact Ampakine CX1739 Exerts Pro-Cognitive Effects and Reverses Opiate-Induced Respiratory Depression in Rodents
(2024-02-26)AMPA-glutamate receptors (AMPARs) are expressed throughout the CNS and mediate the majority of fast excitatory synaptic transmission. Ampakines are orally available small molecules that bind allosterically to AMPARs and ... -
Low-intake dehydration prevalence in non-hospitalised older adults: systematic review and meta-analysis
(2023-08-31)Background & aims Low-intake dehydration amongst older people, caused by insufficient fluid intake, is associated with mortality, multiple long-term health conditions and hospitalisation. The prevalence of low-intake ... -
Low-lying dipole response in the relativistic quasiparticle time blocking approximation and its influence on neutron capture cross sections
(2009-05-15)We have computed dipole strength distributions for nickel and tin isotopes within the Relativistic Quasiparticle Time Blocking Approximation (RQTBA). These calculations provide a good description of data, including the ... -
Low-mass bursty galaxies in JADES efficiently produce ionizing photons and could represent the main drivers of reionization
(2024-01-01)We use deep imaging from the JWST Advanced Deep Extragalactic Survey (JADES) to study the evolution of the ionizing photon production efficiency, ζion. We estimate ζion for a sample of 677 galaxies at z ∼4-9 using NIRCam ...
