Pre-processing whole slide images in cognitive medical pipelines
The invention is notably directed to a computer-implemented method for normalizing medical images, e.g., whole slide images. This method includes steps performed for each image of a first subset of images of a dataset. Actual quantities are estimated for each image, including actual stain vectors and, possibly, robust maximum stain concentrations (typically hematoxylin and eosin stain vectors and concentrations). The actual quantities estimated are assessed by comparing them to reference data based on reference quantities estimated for one or more images of a second subset of images of the dataset, where the second subset of images differ from the first subset of images. The reference quantities include reference stain vectors. For each image, either the actual quantities or the reference quantities for the dataset are selected as effective quantities, based on an outcome of the previous assessment of the actual quantities. Each image is then normalized. |

Repetition reduction for real-time tile-based texture synthesis of aerial imagery
Input coordinates identify a tile on the globe and a biome is identified for each pixel of the tile. We choose a random segmentation mask of the corresponding biome for the tile.

These parameters ensure that (when executed in parallel) each pixel with the same identifier and random value is handled the same way. For each pixel of the tile, using the selected mask, we identify the segment corresponding to that pixel, we retrieve a color variation for that pixel based upon the segment identifier and the random value. We thus choose a color variation for each segment of a segmentation mask. Pixels in the same segment are treated the same way. Instead of a color variation for flat areas (crop fields) we choose a density variation for regions like forests. |

Digital contracts in blockchain environments
Digital or “smart” contracts execute in a blockchain environment. Any entity (whether public or private) may specify a digital contract via a contract identifier in a blockchain. Because there may be many digital contracts offered as virtual services, the contract identifier uniquely identifies a particular digital contract offered by a virtual machine, vendor or supplier. The blockchain is thus not burdened with the programming code that is required to execute the digital contract. The blockchain need only include or specify the contract identifier (and perhaps one or more contractual parameters), thus greatly simplifying the blockchain and reducing its size (in bytes) and processing requirements. |

Barrierless and fenceless shared memory synchronization with write flag toggling
When communicating through shared memory, a producer thread generates a value that is written to a location in a shared memory. The value is read from the shared memory by a consumer thread. The challenge is to ensure that the consumer thread reads the location only after the value is written and is thereby synchronized. When a memory location is written by a producer thread, a flag that is simultaneously stored in the memory location along with the value is toggled. The consumer thread tracks information to determine whether the flag stored in the location indicates whether the producer has written the value to the location. The flag is read and written simultaneously with reading and writing the location in memory, thereby eliminating the need for a memory fence. After all of the consumer threads read the value, the location may be reused to write additional value(s) and simultaneously toggle the flag. |

Provided herein is an electrophoresis separation medium comprising: (a) a non-crosslinked or sparsely cross-linked polymer or copolymer; (b) one or more denaturant compounds, in an amount sufficient to inhibit re-naturation of single stranded polynucleotides; (c) an aqueous solvent; (d) optionally, a wall-coating material suited to inhibition of electroosmotic flow; and (e) optionally, an organic water miscible solvent such as DMSO or acetonitrile, wherein the electrophoresis separation medium exhibits functional stability for at least seven days at 23° C. Also provided herein are sieving compositions, including polymer-based sieving compositions, for molecular sieving as well as related kits, devices and methods of use. Such compositions can be useful for separation of biomolecules such as nucleic acids, proteins, glycoproteins and glycans. |

Systems, apparatuses, and methods for measuring submerged surfaces
The present disclosure provides systems, apparatuses, and methods for measuring submerged surfaces. Embodiments include a measurement apparatus including a main frame, a source positioned outside a pipe and connected to the main frame, and a detector positioned outside the pipe at a location diametrically opposite the source and connected to the main frame. The source may transmit a first amount of radiation. The detector may receive a second amount of radiation, determine a composition of the pipe based on the first and second amounts of radiation, and send at least one measurement signal. A control canister positioned on the main frame or on a remotely operated vehicle (ROV) attached to the apparatus may receive the at least one measurement signal from the detector and convey the at least one measurement signal to software located topside. |

Selecting defect detection methods for inspection of a specimen
Methods and systems for selecting defect detection methods for inspection of a specimen are provided. One system includes one or more computer subsystems configured for separating polygons in a care area into initial sub-groups based on a characteristic of the polygons on the specimen and determining a characteristic of noise in output generated by a detector of an inspection subsystem for the polygons in the different initial sub-groups. The computer subsystem(s) are also configured for determining final sub-groups for the polygons by combining any two or more of the different initial sub-groups having substantially the same values of the characteristic of the noise. In addition, the computer subsystem(s) are configured for selecting first and second defect detection methods for application to the output generated by the detector of the inspection subsystem during inspection of the specimen or another specimen. |

Method and composition for detecting and quantifying filming amines in liquids
A composition and method for the photometric determination of a film-forming amine in liquid by adding an indicator reagent to an aqueous system that is pH dependent, combining a water soluble non-ionic polymer to modify the physical properties of the aqueous system, and adding an acidic buffer to said aqueous system to lower pH and activate said indicator, said water soluble polymer keeping the filming amine/indicator complex in solution despite the acidic buffer and preventing it from precipitating out. |
