Abstract: A key-value store and a file system are integrated together to provide improved operations. The key-value store can include a log engine, a hash engine, a sorting engine, and a garbage collection manager. The features of the key-value store can be configured to reduce the number of I/O operations involving the file system, thereby improving read efficiency, reducing write latency, and reducing write amplification issues inherent in the combined key-value store and file system.

Abstract: A plant-based proteinaceous binder ingredient that is a disturbed-coagulum can be manufactured with disrupting-coagulation treatment described in the application. The binder ingredient improves the handling properties of intermediate products including textured vegetable proteins manufactured using low-moisture protein texturization extrusion. The resulting end-products (formed meat-replacement food products that are meat imitates) show an improved mouthfeel and are highly resistant to bending and suitable for transport. This is believed to relate to a novel self-encapsulated proteinaceous structure of the binder that is assumed to open when being mixed with a sufficiently high mixing power.

The technical method comprises the following steps: extraction of hair follicles; separation of hair follicles; in-vitro culture of hair follicle melanocyte stem cells; inactivation of hair follicles; and transplantation of hair follicle melanocyte stem cells. According to the present disclosure, outer root sheaths of hair follicles containing the hair follicle melanocyte stem cells are obtained through a precise extraction and separation method. Through in-vitro separation and culture and inactivation of hair follicles, a situation that vitiligo only turns black without hairs after surgery is achieved. Through precise transplantation, the original color of the punctate multi-hair follicle orifice can be restored, thereby achieving the purpose of rapidly removing white patches.

Abstract: A method for improving the proteinaceous fibre structure of a textured vegetable protein product, methods of controlling the mouthfeel of a textured protein, and textured vegetable protein products. In the method for improving the proteinaceous fibre structure of a textured vegetable protein product, an extrudate is prepared with an extruder configured to carry out low-moisture protein texturization extrusion, the extrudate including a proteinaceous fibre structure having expansion-related cavities, such as air bubbles, between the proteinaceous fibres; after the extrusion, the extrudate is compressed or compacted in a manner leaving the proteinaceous fibres of the extrudate substantially intact. The compressing or compacting is sustained over a period that causes an irreversible reduction in the size of the expansion-related cavities between the proteinaceous fibres, and preferably also an increase in the bonding between the proteinaceous fibres.
