Abstract: A digital radio OFDM modulator and demodulator provide an efficient mode and a backwards-compatible mode to work with IEEE 802.15.4g or a similar standard. In backwards-compatible mode, they use a single method for error encoding physical header and payload transmit data, and a single method for detecting and correcting errors in physical header and payload receive data. In efficient mode, they use two different methods. The payload is BCH-LDPC encoded. They may also use mapping constellations that are not available in IEEE 802.15.4g, including 64-QAM, 256-QAM, and APSK. To ensure that physical header data can be received more robustly than payload data, they use frequency diversity of the physical header data, and selection maximal ratio combining (SMRC) in the demodulator to reduce the bit error rate (BER) at a low cost.

Abstract: The present disclosure provides methods and compositions for precisely controlling the expression levels of mammalian genes using CRISPRi or CRISPRa and one or more modified sgRNAs. The methods and compositions are useful for, inter alia, titrating the expression of a gene of interest, identifying drug targets and mechanisms of drug resistance, and enabling the analysis of and control over metabolic and signaling pathway fluxes.

At least one contactor is in fluid communication with the first fluid stream inlet and the second fluid stream inlet.

Abstract: A medical imaging device includes an x-ray source disposed at a first end of an arm, and an x-ray detector disposed at a second end of the arm opposite of the x-ray source. At least one of the x-ray source, the x-ray detector, and a portion of the arm are selectively adjustable with respect to the arm.

Abstract: A mobile imaging system or mini C-arm with an increased range of motion is disclosed. The mini C-arm including a mobile base, a C-arm assembly, and an arm assembly for coupling the C-arm assembly and the mobile base. The arm assembly being coupled to the mobile base via a first joint assembly that enables the arm assembly to move relative to the mobile base about first and second axes of rotation. Thus, in use, the first joint assembly enables two degrees of motion—a first vertical pivoting or rotational movement and a second horizontal pivoting or rotational movement. The first joint assembly being coupled to the base via a horizontal axis of rotation that is located at a vertically fixed position so that the horizontal axis of rotation is positioned at a fixed height or distance from the base, and hence a fixed height or distance from the floor.

Abstract: The present invention relates to a method for the production of ethene, CO, and hydrogen in a reactor with a circulating fluidized bed with two independent sections, from feedstocks that contain hydrocarbons with at least 11 carbon atoms or from feedstocks with a high oxygen content, using a catalyst in particulate form. The method teaches that in one of the sections of the reactor, in the absence of oxygen, a catalyst containing a dehydrogenation metal promotes the cracking of the said feedstocks, facilitating the subsequent endothermic reactions. In the other section, the coke is burned with air and the heating of the catalyst is controlled, for the adjustment of the appropriate amount of energy that the heated catalyst will convey to the section in which the endothermic reactions take place. The total ethene yield of the process according to the present invention is approximately 20% by weight in relation to the feedstock.
