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 ... -
Low-mass eclipsing binaries in the WFCAM Transit Survey : The persistence of the M-dwarf radius inflation problem
(2018-06-01)We present the characterization of five new short-period low-mass eclipsing binaries (LMEBs) from the WFCAM Transit Survey. The analysis was performed by using the photometric WFCAM J-mag data and additional low- and ... -
A low-mass neutron flux monitor for the n_TOF facility at CERN
(2004-09)A small-mass system has been developed for monitoring the flux of neutrons with energy up to 1 MeV at the new time-of-flight facility at CERN, n_TOF. The monitor is based on a thin Mylar foil with a Li-6 deposit, placed ... -
Low-mass Objects in Moving Groups
(Astronomical Society of the Pacific, 2010)We present here the kinematic study of part of a 132 target sample of low-mass objects, previously selected by photometric and astrometric criteria as possible members to five young moving groups (MGs): Local Association ... -
A low-mass planet candidate orbiting Proxima Centauri at a distance of 1.5 AU
(2020-01-15)Our nearest neighbor, Proxima Centauri, hosts a temperate terrestrial planet. We detected in radial velocities evidence of a possible second planet with minimum mass m c sin i c = 5.8 ± 1.9 M ⊕ and orbital period P c = ... -
Low-Mass X-ray Binaries and Globular Clusters in Centaurus A
(2007)We present results of Hubble Space Telescope and Chandra X-Ray Observatory observations of globular clusters (GCs) and low-mass X-ray binaries (LMXBs) in the central regions of Centaurus A. Out of 440 GC candidates, we ... -
Low-mass X-ray binaries and globular clusters streamers and ARCS in NGC 4278
(2014-03-01)We report significant inhomogeneities in the projected two-dimensional spatial distributions of low-mass X-ray binaries (LMXBs) and globular clusters (GCs) of the intermediate mass elliptical galaxy NGC 4278. In the inner ... -
Low-metallicity inhibition of type Ia supernovae and galactic and cosmic chemical evolution
(1998-08-20)We introduce a metallicity dependence of the Type Ia supernova (SN Ia) rate into the Galactic and cosmic chemical evolution models. In our SN Ia progenitor scenario, the accreting white dwarf (WD) blows a strong wind to ... -
Low-Power Neuromorphic Hardware for Signal Processing Applications : A review of architectural and system-level design approaches
(2019-11-01)Machine learning has emerged as the dominant tool for implementing complex cognitive tasks that require supervised, unsupervised, and reinforcement learning. While the resulting machines have demonstrated in some cases ... -
Low-power, high-linearity transconductor with a high tolerance for process and temperature variations
(2020-11-18)A novel scheme for tunable complementary metal–oxide–semiconductor (CMOS) transconductor robust against process and temperature (PT) variations is presented. The proposed configuration is a voltage controlled circuit based ... -
A Low-Profile Beam-Steering Reflectarray with Integrated Leaky-Wave Feed and 2-Bit Phase Resolution for Ka-band SatCom
(2021-09-15)A novel reflect array (RA) with ultra-low-profile and 2-bit phase quantization beam-steering ability is presented in this paper. To reduce the profile, a Leaky-wave feed is used to excite the RA with enhanced illumination ... -
Low-Profile Wideband Circularly Polarized Array Antennas Using Integrated Half-Power Quadrature Power Divider
(2022-04-11)Low-profile wideband circularly polarized (CP) array antennas using integrated half-power quadrature power divider (HP-QPD) are presented. A novel HP-QPD is first proposed as an important design concept for CP radiation. ... -
Low-resolution near-infrared spectroscopic signatures of unresolved ultracool companions to M dwarfs
(2017-06-01)We develop a method to identify the spectroscopic signature of unresolved L-dwarf ultracool companions, which compares the spectra of candidates and their associated control stars using spectral ratio differences and ... -
