Abstract: In some examples, novel photochemically-reversible hydrogels and nanogel particles are described comprising copolymer chains including at least one reactive alkene or reactive 1,4-diene end group capable of [2+2] or [2+2+2+2] photodimerization, respectively, at wavelengths >270 nm. In various examples, the photochemically-reversible hydrogels comprise copolymer chains including at least one —N3, —C?CH or —CO2H end group for dual functionality and/or pH responsiveness. For nucleic acid sequencing, amplification primers are grafted to photochemically-reversible hydrogels or nanogel particles reversibly bound to surfaces within a flow cell. After sequencing is complete, the photochemically-reversible hydrogel or nanogel particles is/are removable from the flow cell surfaces by irradiation, enabling the flow cell to be reusable.

Abstract: The method of connection establishment method in data transmission between micro-services in cloud ensures reducing connection complexity between client instances and server instances, increasing the number of connections which helps increase data transmission performance. Besides, the method helps ensure load balancing when server instances change or in time of failure. The proposed method includes the following steps: step 1: data preparation; Step 2: build connection data table; Step 3: select the appropriate connection when receiving a request to send data from the client; step 4: periodically queries the independent service management, updating the current state of the server instances.

Abstract: Hydrocarbon exploration and extraction can be facilitated by determining fault surfaces from fault attribute volumes. For example, a system described herein can receive a fault attribute volume for faults in a subterranean formation determined using seismic data. The fault attribute volume may include multiple traces with trace locations. The system can determine a set of fault samples for each trace location. Each fault sample can include fault attributes such as a depth value, an amplitude value, and a vertical thickness value. The system can determine additional fault attributes such as a dip value and an azimuth value for each fault sample of each trace location. The system can determine fault surfaces for the faults using the fault samples and fault attributes. The system can then output the fault surfaces for use in a hydrocarbon extraction operation.

Abstract: In an approach for compressing a neural network, a processor receives a neural network, wherein the neural network has been trained on a set of training data. A processor receives a compression ratio. A processor compresses the neural network based on the compression ratio using an optimization model to solve for sparse weights. A processor re-trains the compressed neural network with the sparse weights. A processor outputs the re-trained neural network.

Abstract: In some examples, novel nanogel particles are described having dual functionality, temperature responsiveness and pH responsiveness. For nucleic acid sequencing, amplification primers are grafted to nanogel particles to form primer-grafted nanogel particles, and the primer-grafted nanogel particles are captured onto surfaces within a flow cell. Within flow cells such as used in SBS nucleic acid sequencing, each primer-grafted nanogel particle functions as a nano-well in the flow cell, thus eliminating the need for nano-wells in some examples.

Abstract: A method to detect, identify and determine the position of laser points from infrared laser emitters in a firearm training simulation system. The method consists of two steps. This first step combines some common tools such as a camera with a filter switcher and edge and corner detecting algorithms in image processing to provide a fast automatic screen calibrating method. The second step is to detect laser point objects in each frame continuously captured by the camera, and then further process these objects to identify laser shots, filter out noisy objects, and eventually detect simulated shots from different laser emitters and determine the final mapped position of the shot.

Abstract: In one example, a notification may be generated to prompt a user to clean a personal computing device. The notification may be based upon usage data of the personal computing device. Multiple types of usage data may be determined and combined to create a composite usage value. The composite usage value may be compared to a threshold usage value. A notification may be generated if the composite usage value exceeds the threshold usage value.

Abstract: The present invention relates to a method of determining the wind speed in the plane of a rotor (PR) of a wind turbine (1), by measuring (MES2) the rotational speed of the rotor, the angle of the blades and the generated power. The method according to the invention uses a wind turbine model (MOD) constructed from wind speed measurements (LID), and by use of measurement clustering (GRO) and regressions (REG).

Abstract: The disclosure presents processes to automatically generate one or more set of fault segments from a fault plane pointset. The processes can identify a predominant direction and derive a set of fault segments from the fault plane pointset, where the fault segments are generated by using slices of data from the fault plane pointset that are perpendicular to the predominant direction. For each slice of data, the fault segments can be analyzed with neighboring fault segments to determine if they are overlapping. Fault segments that block or overlap other fault segments can be assigned to a different subset of fault segments from the underlying fault segments. Gaps in the fault plane pointset, and the resulting set of fault segments, can be filled in by merging neighboring fault segments above and below the gap if the neighboring fault segments satisfy a criteria for filling the gap.
