Abstract: Processes and apparatuses for treating NOx from a carbon dioxide stream. Prior to separating carbon dioxide and NOx, NOx is converted to nitrogen gas in an NOx conversion zone, which may include an SCR reactor and/or CO boiler. A carbon separation zone which may include one or more fractionation columns produces a CO2 stream and an NOx stream. The NOx is passed back to the NOx conversion zone.

Abstract: An indoor disinfection system has a collection of lighting units. Each lighting unit includes a germicidal ultraviolet (GUV) light source emitting a GUV light cone with a cone angle less than 60 degrees. The GUV light cone contains optical power with wavelengths between 10-280 nm. A human presence sensor has a field of view cone angle greater than the GUV light cone angle. The human presence sensor generates a human presence signal in response to a human in the field of view. A controller receives the human presence signal and in response thereto disables the GUV light source.

Abstract: The present disclosure relates to a system and method for generating medical notes in real-time using a mobile device. The system employs a local, real-time speech recognition model to transcribe medical conversations accurately without relying on cloud-based processing. The transcribed text is then sent to a cloud-based LLM for summarization and generation of a comprehensive medical note. The local speech recognition model is pre-trained on a dataset comprising numerous medical terms and phrases, and it can be iteratively improved through user feedback and additional training. This innovative approach eliminates the ongoing costs associated with cloud-based transcription services while ensuring data privacy and security by keeping sensitive patient information on the mobile device. The system offers the ability to deliver a better product at a price point an entire order of magnitude lower than our competitors.

Abstract: A process for supplementing production of liquid fuel from carbon oxides is disclosed. The process comprises contacting a hydrocarbon feed stream with a catalyst in a reactor to produce a reactor effluent stream. The reactor effluent stream is separated to provide a dry gas stream. The dry gas further separated into a CO2 rich stream and a CO2 lean stream. The CO2 lean stream is used to produce methanol. The methanol is contacted with an MTO catalyst to produce an olefin stream. The olefin stream is oligomerized by contacting it with an oligomerization catalyst in an oligomerization reactor to produce an oligomerized olefin stream which is further hydrogenated. A sustainable aviation fuel is taken from the hydrogenated oligomerized stream.

Abstract: An apparatus has a current spreading base with an n-contact. The current spreading base has a small n-type resistivity to promote lateral electron flow. A current spreading cap is on top of the current spreading base. The current spreading cap has a large n-type resistivity to suppress vertical electron flow and promote lateral electron flow. An active region is on top of the current spreading cap. A p-type structure is on top of the active region with a p-contact. Sheet resistance of the current spreading base is experimentally established, the half width xF of a mesa is selected and the current spreading cap thickness hc is selected to collectively promote uniform current injection into the active region.

Abstract: We have discovered a process for catalytic production of olefins comprising passing a feed stream to an isomerization unit to provide a first hydrocarbon stream rich in iso-paraffins. The first hydrocarbon stream is contacted with a first stream of fluid catalyst in a first reactor riser to produce a first mixture of spent catalyst and product gases. The first mixture of spent catalyst and product gases is separated into a first cracked product stream and a first stream of cool catalyst. A dilute ethylene stream is separated from the first cracked product stream which is oligomerized to produce a second hydrocarbon stream comprising C4+ oligomers. The second hydrocarbon stream is contacted with a second stream of fluid catalyst in a second reactor riser to produce a second mixture of spent catalyst and product gases.

Abstract: Use of a gene ZmNPF6.8 in regulation of a nitrogen uptake and utilization efficiency of Zea mays L. and a yield per Zea mays L. plant is provided. The gene ZmNPF6.8 has: 1) a coding region nucleotide sequence shown in SEQ ID NO: 3; or 2) a nucleotide sequence that has 90% or more homology with the coding region nucleotide sequence shown in SEQ ID NO: 3 and encodes a same functional protein as the coding region nucleotide sequence shown in SEQ ID NO: 3.

Abstract: The present application belongs to the technical field of gene therapy, and discloses a method for treating a tumor with a combination of an exogenous antigen and a therapeutic agent. The present application also discloses a composition including an exogenous antigen and a therapeutically effective amount of a therapeutic agent. With the exogenous antigen as a target, the therapeutic agent kills a tissue or cell carrying the exogenous antigen and does not act on any tissue or cell without the exogenous antigen, thereby specifically killing the tissue or cell, such as a tumor cell. Since the exogenous antigen can be expressed in different types of tumors in different individuals, the method of the present application is a broad-spectrum anti-tumor method.
