Abstract: Current laboratory procedures for detection of a virus using the specimens collected from upper respiratory systems involve RNA isolation from the specimen, cDNA synthesis via reverse transcription, amplification of the target region via LAMP reaction, and detection. The present invention performs alternative ways of LAMP reactions in which every single key component in the traditional system is reorganized to achieve operational LAMP protocols. The present invention skips the RNA isolation and purification steps which decrease the overall cost, and the test time by more than 20 minutes. This method can also be applicable for analysis of other viruses and some pathogens in several fields.

Abstract: There is provided a biofilm capacitance microbial electrochemical cell (MEC) sensor to measure organic carbon in water and wastewater rapidly and accurately, represented by the 5-day biochemical oxygen demand (BOD5). The MEC runs at charging (open circuit) and discharging (close circuit) conditions alternately to improve the sensitivity, response time and accuracy. The detectable BOD5 concentrations with the biofilm-capacitance MEC range from 5 to 250 mg/L (R2>0.9). The MEC sensor enables BOD5 measurements at every 2 minutes (1 minute charging and 1 minute discharging), indicating semi-continuous quantification of organic carbon in water and wastewater.

Abstract: A multi-view planar near-field scattering tomography system is provided herein. In one aspect the system is developed based on the reformulated signal subspace approach. Utilized for solving the electromagnetic inverse scattering problem, the signal subspace approach is reformulated. The present invention pertains to a computationally efficient approach to an electromagnetic inverse scattering-based permittivity profile estimation technique. In a second aspect, the system is developed at the millimeter-wave and THz frequency range to ensure accuracy by eliminating the multipath effects and without the need for an Anechoic chamber or water as a background medium for clinical, security, and manufacturing applications.

Abstract: There is provided a fiber-based broadband polarization-entangled photon source. The polarization entangled photon pair source module comprises an optical fiber, a pump to couple light into the fiber and one or more suppression filters following the fiber. The optical fiber preferably is a periodically poled silica fiber and the pump is preferably a laser diode pump. The present invention relates to a compensation-free, alignment-free, diode-pumped, broadband, polarization-entangled photon source that is based on a low-birefringence fiber. It has an extremely simple configuration capitalizing on the compensation-free and direct generation capability of a low-birefringence fiber. The source has broad bandwidth, high-quality and polarization-entanglement. The present invention is compact, robust, low-power, low-cost, alignment-free and room-temperature operable, featuring a simple turn-key, plug-and-play operation.

Abstract: The present invention presents a flexible, stepped frequency, radar based, imaging inspection system. The imaging inspection system can be used in airports, seaport sites, borders, postal processing centres, and sensitive sites. It comprises a millimetre-wave Stepped Frequency Continuous Wave (SFCW) radar module (2) connected to a transmitting channel and a receiving channel. The transmitting channel may comprise a frequency upconvertor (8) and the receiving channel may comprise a frequency downconvertor (10). A digital signal processing unit (14) reconstructs a conductivity profile and a permittivity profile of an object under test (OUT) from measurement data collected via a phase-array antenna or a translational stage (18) based on synthetic aperture focusing (SAF).
