Abstract: Techniques are described for a multiple-phase process that uses machine learning (ML) models to produce a texturized version of an input image. During a first phase, using a pix2pix-based ML model, an automatically-generated image that depicts structured texture is generated based on an input image that visually identifies a plurality of image areas for the structured texture. During a second phase, a neural style transfer-based ML model is used to apply the style of a style image (e.g., a target image from the training dataset of the pix2pix-based ML model) to the texture image generated at the first phase (the content image) to produce a modified texture image. According to an embodiment, during a third phase, the generated texture image produced at the first phase and the modified texture image produced at the second phase are combined to produce a structured texture image with a moderated amount of detail.

Abstract: A method for preparation of conductive polymer/carbon nanotube (CNT) composite nanofiltration (NF) membrane and the use thereof. This conductive polymer/CNT composite NF membrane is obtained by polymerizing conductive polymer into a CNT membrane and then in-situ cross-linking with glutaraldehyde under acidic condition. The synthetic method for the conductive polymer/CNT composite NF membrane is simple and has no need of expensive equipment. The prepared membrane has controllable membrane structure and possesses superior electrical conductivity and electrochemical stability. The membrane can couple with electrochemistry for electrically assisted filtration. With the electrical assistance, the membrane can achieve improved ion rejection performance while retaining high permeability by enhancement of membrane surface charge density, which alleviates the permeability-selectivity trade-off.

Abstract: A mapping correspondence between memory addresses and request counts and a cache line flusher are provided, enabling selective cache flushing for persistent memory in a computing system to optimize write performance thereof. Random writes from cache memory to persistent memory are prevented from magnifying inherent phenomena of write amplification, enabling computing systems to implement persistent memory as random-access memory, at least in part. Conventional cache replacement policies may remain implemented in a computing system, but may be effectively overridden by operations of a cache line flusher according to example embodiments of the present disclosure preventing conventional cache replacement policies from being triggered. Implementations of the present disclosure may avoid becoming part of the critical path of a set of computer-executable instructions being executed by a client of cache memory, minimizing additional computation overhead in the critical path.

Abstract: A key-value store is provided, implementing multiple-tiered sorted data structures in memory and storage, including concurrent write buffers in memory, and page-level consolidation of updates on storage, where pages are trivially translated in physical-to-virtual address mapping. The key-value store is built on an indexed sorted data structure on storage, occupying much less storage space and incurring much less disk activity in consolidating updates than a conventional log-structured merge tree organized into files. Concurrent write buffers operate concurrently and independently so that data is committed from memory to storage in an efficient manner, while maintaining chronological sequence of delta pages. Trivial mapping allows mappings of a number of physical pages to be omitted, enabling page mapping tables to occupy less storage space, and simplifying processing workload of read operation retrievals from storage.
