This paper presents improvements in flow detection by electrical cross-correlation spectroscopy. This new technique detects molecular number fluctuations of electrochemically active analyte molecules as they are transported by liquid flow through a nanochannel. The fluctuations are used as a marker of liquid flow as their time of flight in between two consecutive transducers is determined, ther...

Quantum entanglement in macroscopic systems plays an important role quantum information processing. Here, we show that the steady-state between two cavity modes Laguerre–Gaussian (L–G) optorotating system can be enhanced by placing a degenerate optical parametric amplifier (OPA) inside cavity. The L–G are coupled to same rotating mirror and respectively driven at red blue mechanical sidebands. ...

BACKGROUND The influence of diabetes mellitus on ocular pulse amplitude (OPA), an indirect measure of choroidal perfusion, is unclear. METHODS OPA, using the Langham ocular blood flow (OBF) system, applanation intraocular pressure (IOP), systemic blood pressure (BP), heart rate, and haemoglobin (Hb) A(1c) were measured in patients with insulin dependent diabetes mellitus (IDDM) with no (DR-0,...

We demonstrate the generation of 22.6 μJ of combined energy at 3 μm for sub-300fs pulses at a repetition rate of 1 kHz using a LGSe optical parametric amplifier (OPA). The LGSe OPA is pumped by the 140-fs 1.6 μm pulses from a 300-mW KTA optical parametric chirped pulse amplifier (OPCPA) based on an all-optical synchronization scheme. By using a highly-nonlinear fiber, the output of an erbium-do...
