摘要： A method for characterizing a subsurface formation includes receiving image data of the subsurface formation obtained by a sensor tool and receiving a plurality of non-image data logs, each non-image data log being obtained by a different type of sensor tool. The method also includes performing an electrofacies analysis on the plurality of non-image data logs where the electrofacies analysis includes defining clusters wherein each cluster has a similar property to provide a plurality of electrofacies blocks with each electrofacies block representing a depth interval. The method further includes partitioning the image data into multiple high-resolution depth segments that share a similar property, feature, and/or pattern for each electrofacies block and assigning data from the plurality of non-image data logs into a corresponding high-resolution depth segment to provide a high-resolution data log that characterizes the subsurface formation.

摘要： Disclosed is a diacylglycerol acyltransferase 1, a recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1, and application thereof in production of triacylglycerol. The diacylglycerol acyltransferase 1 of the invention has a function of catalyzing synthesis of triacylglycerol. After the recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1 of the invention is subjected to induction culture for 48 h, the content of total fatty acid and triacylglycerol in the recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1 can be respectively increased by 1.94 folds and 12.09 folds as compared with those of Saccharomyces cerevisiae without the recombinant diacylglycerol acyltransferase 1. The instant invention provides a method for improving the ability of microorganisms to produce polyunsaturated fatty acids (PUFAs) by means of genetic engineering.

摘要： The present disclosure is directed to a computer-implemented method for designing a patient-specific brachytherapy (BT) tandem applicator. The method is implemented using at least one processor in communication with at least one memory. The method includes receiving a radiation treatment plan for treating a region of interest. The radiation treatment plan includes a prescribed radiation dosage and patient anatomical data of the region of interested to be treated. The method also includes applying an inverse planning optimization model to determine an optimal thickness of an interior surface of the tandem applicator at a plurality of dwell positions within the region of interest. The method also includes generating a schedule of dwell times for the tandem applicator based on the generated position-dependent thickness profile. The method also includes transmitting design instructions to a 3D printer for fabrication of the tandem applicator.

摘要： A computer system for distinguishing user-initiated network traffic from malware-initiated network traffic comprising at least one central processing unit (CPU) and a memory communicatively coupled to the CPU. The memory includes a program code executable by the CPU to monitor individual network events to determine for an individual network event whether the event has a legitimate root-trigger. Malware-initiated traffic is identified as an individual network event that does not have a legitimate root-trigger.

摘要： A process for separating components of a gas mixture using gas-separation copolymer membranes. These membranes use a selective layer made from copolymers of partially fluorinated or perfluorinated dioxolane monomers and a second monomer, such as dioxane or a partially fluorinated dioxolane. The resulting membranes have superior selectivity performance for gas pairs of interest while maintaining fast gas permeance compared to membranes prepared using conventional perfluoropolymers, such as Teflon® AF, Hyflon® AD, and Cytop®.

摘要： In various embodiments, a screen image may be divided into rectangles, and a capture component may track changed rectangles and capture the screen upon receiving an indication. For small screen updates, the capture rate may be set to ˜30 captures per second to provide a lower latency. As the screen update size increases, the capture rate may be decreased to match an allocated bandwidth. The capture rate may be increased when available bandwidth increases and decreased as bandwidth decreases. For example, the capture rate may be decreased when downstream back pressure meets predefined criteria. The capture rate change may be effected gradually to avoid jerks and jumps. Varying the capture rate by also enable audio/video synchronization with varying bandwidth variations. Some embodiments may be extended to multiple monitor solutions.

摘要： The present invention extends to methods, systems, and computer program products for providing domain, hull, and geometry shaders in a para-virtualized environment. As such, a guest application executing in a child partition is enabled use a programmable GPU pipeline of a physical GPU. A vGPU (executing in the child partition) is presented to the guest application. The vGPU exposes DDIs of a rendering framework. The DDIs enable the guest application to send graphics commands to the vGPU, including commands for utilizing a domain shader, a hull shader, and/or a geometric shader at a physical GPU. A render component (executing within the root partition) receives physical GPU-specific commands from the vGPU, including commands for using the domain shader, the hull shader, and/or the geometric shader. The render component schedules the physical GPU-specific command(s) for execution at the physical GPU.
