Abstract: An estimated or predicted dose for radiotherapy treatment may be generated based on a partial dose map including dose information only for one or more regions of interest within a treatment site, by use of a properly trained machine learning system such as a U-Net or a V-Net. Said partial dose map typically set to fulfil clinical goals. A method of training such a machine learning system is also disclosed.

Abstract: A request for an estimated temperature of a memory sub-system including multiple components can be received. A set of component temperature values based on temperature measurements at the components can be identified. A subset of the component temperature values can be generated by removing one or more of the component temperature values from the set of component temperature values based on one or more criteria. The estimated temperature value that estimates the temperature of the memory sub-system can be generated using the subset of the component temperature values.

Abstract: A duration of time for a first idle state of a memory sub-system is determined, where the memory sub-system includes an active state and a second idle state. A first command is received to transition from the active state to the second idle state. In response to the first command, the memory sub-system is transitioned to the first idle state. The memory sub-system is transitioned from the first idle state to the second idle state in response to an expiration of the duration of time.

Abstract: A transitory idle state is established for a memory sub-system that can be transitioned from an active state to one or more idle states including the transitory idle state and a deep idle state. A power consumption metric and transition time for each idle state is identified. A transitional energy metric is determined for each idle state based on the corresponding power consumption metric transition time. An energy target time is determined for the transitory idle state. Based on the energy target time, an idle state optimization time is determined for the transitory idle state. The memory sub-system is maintained in the transitory idle state for a duration of the idle state optimization time.

Abstract: Disclosed is a method for the removal of ammonia from the off-gas of a finishing section of a urea production plant. The method comprises contacting the off-gas with a solid adsorbent capable of physically adsorbing ammonia, particularly activated carbon or zeolite. Thereupon the solid adsorbent having ammonia adsorbed thereon is separated from the gas and regenerated by dissolving ammonia in an extraction liquid, preferably water. After separating the water from the solid adsorbent, the latter is re-used in the process.

Abstract: An optical recording system writes data on an optical disk that has a user data area having a plurality of sectors and that has a map having first and second indicators corresponding to a portion of the plurality of sectors. The first indicator has a first logic state indicating that a corresponding sector contains data and has a second logic state indicating that the corresponding sector does not contain data. The second indicator has a first logic state indicating that the corresponding sector is to be erased. A recorder is coupled to the optical disk for erasing data and the indicators from the sectors and the map, respectively, in response to an erase command. The recorder writes data and the indicators on the sectors and the map, respectively, in response to a write command.

Abstract: An optical disk drive is located in a housing having a centrally pivoted door. An optical disk cartridge is inserted into the drive and is received by a sealing member. The cartridge and sealing member divides the interior of the drive into two compartments. The first compartment contains the electronics which need to be cooled and the second compartment contains the optical elements. The door and sealing member allow airflow in the first compartment but prevent it from reaching the second compartment. An airfoil is positioned over the optical elements in the second compartment to protect them from airflow developed by the spinning disk.
