Characterization of heterodyne optical phase locking for relative laser frequency noise suppression in differential measurement Open
Laser frequency noise is particularly challenging to mitigate in low Fourier frequency measurement. For differential measurement schemes using heterodyne optical phase-locked loops, this noise can be common-mode suppressed in the final rea…

Is Wear Still a Concern in TKA With Contemporary Conventional and Highly Crosslinked Polyethylene Tibial Inserts in the Mid- to Long-Term? Open
Background Modern literature has brought into question if wear of tibial inserts made from conventional or highly-crosslinked polyethylene (HXL PE) is still a factor limiting longevity of total knee arthroplasty (TKA) in the mid- to long-t…

The torsion pendulum dual oscillator for low-frequency Newtonian noise detection Open
We present a torsion pendulum dual oscillator sensor designed toward the direct detection of Newtonian noise. We discuss the sensitivity limitations of the system, experimental performance characterization results, and prospectives to impr…

Frequency noise stabilisation of a 1550 nm external cavity diode laser with hybrid feedback for next generation gravitational wave interferometry Open
Longer wavelength lasers will be needed for future gravitational wave detectors that use cryogenic cooling of silicon based test-mass optics. Diode lasers with a 1550 nm wavelength output are potential seed light sources for such a detecto…

Quantum noise cancellation in asymmetric speed metres with balanced homodyne readout Open
The Sagnac speed metre topology has been identified as a promising technique to reduce quantum back-action in gravitational-wave interferometers. However, imbalance of the main beamsplitter has been shown to increase the coupling of laser …

Effects of static and dynamic higher-order optical modes in balanced homodyne readout for future gravitational waves detectors Open
With the recent discovery of Gravitational waves, marking the start of the\nnew field of GW astronomy, the push for building more sensitive\nlaser-interferometric gravitational wave detectors (GWD) has never been\nstronger. Balanced homody…

Candidates for a possible third-generation gravitational wave detector: comparison of ring-Sagnac and sloshing-Sagnac speedmeter interferometers Open
Speedmeters are known to be quantum non-demolition devices and, by potentially providing sensitivity beyond the standard quantum limit, become interesting for third generation gravitational wave detectors. Here we introduce a new configura…

Dietary nitrate supplementation: impact on skeletal muscle vascular control in exercising rats with chronic heart failure Open
Chronic heart failure (CHF) results in central and peripheral derangements that ultimately reduce skeletal muscle O 2 delivery and impair exercise tolerance. Dietary nitrate (NO 3 − ) supplementation improves skeletal muscle vascular funct…
