  • Patent number: 12685981
    Abstract: A reactor and method for the conversion of hydrocarbon gases utilizes a reactor (12, 312, 412, 512, 612, 712) having a unique feed assembly with an original vortex combustion chamber (40, 340, 436, 536, 636, 736), a diverging conduit (48, 348, 448, 548, 648, 748), and a cylindrical reactor chamber (40, 340, 436, 536, 636, 736). This design creates a compact combustion zone and an inwardly swirling fluid flow pattern of the feed gases to form a swirling gas mixture that passes through a diverging conduit (48, 348, 448, 548, 648, 748). The feed streams can be introduced into the reactor at any angle (perpendicular, axial, or something between, or a combination of the above forms) with swirling flow components. This provides conditions suitable for efficient cracking of hydrocarbons, such as ethane, to form olefins.

  • Patent number: 12688943
    Abstract: Disclosed is a solid lithium-lead blanket for a fusion reactor, where a solid lithium-lead alloy is adopted as a neutron multiplier and a tritium breeder, and is placed in a form of a unitary or binary pebble bed inside a structural skeleton composed of structural materials; and nuclear thermal deposition in the solid lithium-lead alloy generated due to an interaction between the solid lithium-lead alloy and a fusion neutron is moved out by a coolant. A proportion of lead atoms in the solid lithium-lead alloy is low, so that, under normal operations and accident conditions of the blanket, the solid lithium-lead alloy always remains in a solid state without melting, and tritium can be brought out of the reactor by purge gas flowing through the pebble bed to allow tritium self-sufficiency. The blanket of the present disclosure does not require beryllium to meet the requirements of tritium breeding.

  • Patent number: 12682982
    Abstract: The disclosure generally pertains to providing an accurate genotype for high repeat genes. First, repeat structures of sequencing reads are identified and sequence reads with abnormal repeat structures are removed to generate a first dataset. The sequence reads of the first dataset are filtered to exclude sequences with structural artifacts to generate a second dataset. Data from the second dataset is input to a model to generate a third dataset, the third dataset including sequencing reads categorized by allele. Next, a consensus sequence is generated for each allele in the third dataset to generate a fourth dataset of consensus reads for all alleles in the third dataset. Each allele of the fourth dataset is translated to generate a fifth dataset, the fifth dataset including the corresponding amino-acid sequence of each allele. A protein-altering variant status is then determined based on the amino-acid sequences of the fifth dataset.

  • Patent number: 12677321
    Abstract: Embodiments of this application disclose a random access method and apparatus. In one example method, when a terminal device supports positioning, the terminal device may adjust, based on a positioning capability, time for sending a preamble on a RACH Occasion (RO) resource. When the terminal device does not support positioning, a corresponding RO resource periodicity may be configured to be large. Therefore, regardless of whether the terminal device supports positioning, a network device can receive, at the same time or in a short preamble receiving time window, preambles sent on a same RO resource, and receive, at different time, in different small time ranges, or in different short preamble receiving time windows, preambles sent on different RO resources.
