Abstract: For computers to be able to make informed decisions (aka artificial intelligence), they must convert raw sensor data into an actionable information, using some form of ‘world model’. ‘Traditional’ algorithms use a human engineered model, tailored to the specific problem at hand. These algorithms typically required only limited amount of data samples during design/training, due to the narrow area of applicability and the limited number of free parameters.

Abstract: With increasing complexity of computer programs, no single person or groups is able to build an application from scratch. In nearly all scenarios, new applications are built on-top of existing components/services, which are out-side of the control of the application developers.

Abstract: Electron capture dissociation (ECD) is performed by transmitting an electron beam through a cell along an electron beam axis, generating plasma in the cell by energizing a gas with the electron beam, and transmitting an ion beam through the interaction region along an ion beam axis to produce fragment ions. Generating the plasma forms an interaction region in the cell spaced from and not intersecting the electron beam, and including low-energy electrons effective for ECD. The ion beam axis may be at an angle to and offset from the ion beam axis, such that the electron beam does not intersect the ion beam.

Abstract: The invention relates to a method and system for cooling a natural gas feed stream and recovering a natural gas liquid stream from the natural gas feed stream using an expansion-based cooling unit and a natural gas liquid removal unit which are integrated. The integration is done by using (part of) a cooling stream from the expansion-based cooling unit to provide cooling duty to the natural gas liquid removal unit.

Abstract: An ion source includes a plasma generator for supplying plasma at an ionization region proximate to a sample surface. The plasma generator applies energy that may be utilized for desorbing analytes from the sample surface as well as for generating plasma by which analytes are excited or ionized. Desorption and ionization/excitation may be controlled as individual modes. The ion source may be interfaced with an ion-based or optical-based spectrometer. A sample support may be provided, which may be capable of performing analytical separation.

The system may be switched between operating in an analytical mode and in a cleaning mode. In the analytical mode a sample is analyzed, and plasma may or may not be actively generated. In the cleaning mode the plasma is actively generated, and the sample may or may not be analyzed.

Abstract: An electron capture dissociation (ECD) apparatus includes a plasma source for generating plasma. Analyte ions are exposed to the plasma in an ECD interaction region, either inside or outside the plasma source. The apparatus may include one or more devices for refining the plasma in preparation for interaction with the analyte ions. Refining may entail removing unwanted species from the plasma, such as photons, metastable particles, neutral particles, and/or high-energy electrons unsuitable for ECD, and/or controlling a density of low-energy electrons in the plasma.

Abstract: A photon source includes a plasma source for generating plasma and a photon guide through which the plasma travels. The photon guide includes an inner surface configured for reflecting photons emitted from the plasma. As the plasma travels through the photon guide, plasma electrons and ions recombine at the inner surface, whereby the predominant species emitted from an outlet of the photon guide are the photons and neutral particles, with few or no plasma electrons and ions being emitted.
