Systems and methods for measuring flow velocity of a fluid mixture in a lateral section of an oil/gas/water well with a dual beam laser doppler velocimetry (LVD) based flow sensor are presented. According to one aspect, the flow velocity is measured by tracking movement of particles and/or features in the fluid mixture while traversing an interference pattern generated by the intersection of two separate coherent beams that are perpendicular to a direction of the flow. Flow velocity is derived based on a time it takes the particles to traverse consecutive fringes of the interference pattern as indicated by intensity peaks detected at the photodetector. The LDV-based flow sensor may be rotatable to measure flow velocities at different angular positions of a pipe in a lateral section of an oil well, rotation provided by rotation of an element of a mobile vessel to which the flow sensor is rigidly coupled.

The present disclosure is directed toward systems and methods for measuring electric current in a multi-wire cable, as well as the apparent and real power associated with an electrical load connected to the cable. A probe comprising an array of small form-factor, high-speed magnetometers is operatively coupled with the cable such that the magnetometers partially surround the cable.

A sensor included in the probe is used to determine the phase of the applied voltage. The phase difference between the voltage and current is then used to determine the real power dissipation of the load.

Systems and methods for transmitting data using various Modulation on Zeros schemes are described. In many embodiments, a communication system is utilized that includes a transmitter having a modulator that modulates a plurality of information bits to encode the bits in the zeros of the z-transform of a discrete-time baseband signal. In addition, the communication system includes a receiver having a decoder configured to decode a plurality of bits of information from the samples of a received signal by: determining a plurality of zeros of a z-transform of a received discrete-time baseband signal based upon samples from a received continuous-time signal, identifying zeros that encode the plurality of information bits, and outputting a plurality of decoded information bits based upon the identified zeros.
This invention provides methods and systems for measuring the concentration of multiple nucleic acid sequences in a sample. The nucleic acid sequences in the sample are simultaneously amplified, for example, using polymerase chain reaction (PCR) in the presence of an array of nucleic acid probes. The amount of amplicon corresponding to the multiple nucleic acid sequences can be measured in real-time during or after each cycle using a real-time microarray. The measured amount of amplicon produced can be used to determine the original amount of the nucleic acid sequences in the sample. Also provided herein are biosensor arrays, systems and methods for affinity based assays that are able to simultaneously obtain high quality measurements of the binding characteristics of multiple analytes, and that are able to determine the amounts of those analytes in solution. The invention also provides a fully integrated bioarray for detecting real-time characteristics of affinity based assays.
The invention provides broadly neutralizing antibodies directed to epitopes of Human Immunodeficiency Virus, or HIV. The invention further provides compositions containing HIV antibodies used for prophylaxis, and methods for diagnosis and treatment of HIV infection.
A sensor implanted in tissues and including a sensing layer is fabricated by mixing the signal transduction enzyme with non-reactive components including buffer salts and fillers, and spin coating the enzyme onto a substrate. The signal transduction enzyme is crosslinked by introducing the coated substrate in a vacuum chamber. In the chamber, a crosslinker evaporates and is deposited onto the enzyme, therefore crosslinking the enzyme.

Disclosed herein include novel blood-brain barrier (BBB)-crossing receptors on the BBB interface, targeting peptides and derivatives thereof capable of binding to the novel receptors, and related methods of using the receptors to increase the permeability of the BBB and to deliver an agent to a nervous system (e.g., CNS). In some embodiments, the BBB-crossing receptor is carbonic anhydrase IV. Disclosed herein also include recombinant adeno-associated viruses (rAAVs) with increased specificity and transduction efficiency across the BBB and related compositions and methods of treating various diseases and conditions.
Systems and methods for sensing and measuring local pH, pOH, and other protonic species using reversible excited-state photoacids and photobases are described. Various reversible excited-state photoacids and/or photobases are described that through a dynamic sensing mechanism exhibit varied fluorescence or phosphorescence intensity based on local activity of protonic species. Photoacids and photobases can be used in combination with confocal fluorescent microscopy for quantifying local activity of protonic species.
