Characterisation of Low Frequency Gravitational Waves from Dual RF Coaxial-Cable Detector: Fractal Textured Dynamical 3-Space
Low Frequency Gravitational Waves Dual RF Coaxial-Cable Detector Fractal Textured Dynamical 3-Space
2012/5/17
Experiments have revealed that the Fresnel drag effect is not present in RF coaxial cables, contrary to a previous report. This enables a very sensitive, robust and compact detector, that is 1st order...
Low Frequency Approximation for a class of Linear Quantum Systems using Cascade Cavity Realization
Quantum Linear Systems Model Reduction Cascade Realization
2011/10/10
Abstract: This paper presents a method for approximating a class of complex transfer function matrices corresponding to physically realizable complex linear quantum systems. The class of linear quantu...
Very Low Frequency QPO in 4U1700-37

2011/9/29
Very low frequency ({\nu} ~ 1.9 mHz) quasi-periodic oscillations (QPO) have been detected in 2 - 60 keV X-rays from 4U1700-37 using auto-correlation function analysis of RXTE archival data. No pulsar ...
A low frequency study of PSRs B1133+16, B1112+50, and B0031-07
low frequency study PSRs B1133+16
2011/1/13
The low frequency (110--180 MHz) capabilities of the Westerbork Synthesis Radio Telescope (WSRT) are used to characterise a large collection of single pulses from three low magnetic field pulsars. Usi...
We consider Morawetz estimates for weighted energy decay of solutions to the wave equation on scattering manifolds (i.e., those with large conic ends). We show that a Morawetz estimate persists for so...
Radio Halos and the importance of future observations at low frequency
Radio Halos future observations low frequency
2010/11/11
Radio observations discovered large scale non thermal sources in the central Mpc regions of
dynamically disturbed galaxy clusters (radio halos). The morphological and spectral properties of these sou...
The response of giant kelp (Macrocystis pyrifera) in southern California to low-frequency climate forcing
giant kelp southern California
2014/4/17
The nutrient climate on the inner shelf off southern California changed markedly across the 1976–1977 North
Pacific climate regime shift. With respect to giant kelp (Macrocystis pyrifera) canopies of...
Electron Temperatures in W51 Complex from High Resolution, Low Frequency Radio Observations
ISM—HII regions—radio continuum—individual (W51)
2010/9/15
W51 is a giant radio complex lying along the tangent to the Sagitarius arm at a distance of about 7 kpc from the Sun, with an extension of about 1◦ in the sky. It is divided into three component...

2009/12/10
Ultra low frequency, kHz and MHz electromagnetic (EM) anomalies were recorded prior to the L'Aquila catastrophic earthquake that occurred on 6 April 2009. The main aims of this paper are threefold: (i...
Ocean Acidification and the Increasing Transparency of the Ocean to Low-Frequency Sound
Ocean acid boric acid to dissolve carbonate ions sound waves Marine mammals
2015/7/6
As the ocean becomes more acidic, low-frequency (~ 1–3 kHz and below) sound travels much farther due to changes in the amounts of pH-dependent species such as dissolved borate and carbonate ions, whic...
