Cache management using cache scope designation
To facilitate an efficient processing of contended cache lines, a cache controller that is associated with a requestor receives a fetch request for data from the requestor.

Auto-detection of interconnect hangs in integrated circuits
A self-detection mechanism for an IC is disclosed that determines whether the IC's internal bus is in a hanging state. An initialization sequence can be modified after a soft reset by reading data from an internal DRAM of the IC using a Direct Memory Access (DMA) controller as part of the initialization sequence. The read command is issued over the internal bus and, if the bus is hanging, the read command is not completed. Monitoring can be performed by waiting a predetermined period of time (e.g., 100 ms) to determine if the read was properly completed. If so, no further action is needed. If the read was not completed, then a hard reset is requested to be performed. Thus, an initialization sequence can be modified to run dummy transactions through the internal bus, and validate that all paths are functional. |

Method for exploiting underground resources with negative thixotropic fluid
Embodiments of the present disclosure relate to a method of exploiting underground resources with a negative thixotropic fluid, which induces the fault or the fracture to slip by replacing a conventional mode of injecting water with a mode of injecting the negative thixotropic fluid. According to the negative thixotropy of the injected fluid, when the fault or the fracture does not slip, viscosity of the negative thixotropic fluid is low, and the negative thixotropic fluid could flow in the fracture network. When the fault or the fracture slips, a great shear strain rate is generated, such that the viscosity of the negative thixotropic fluid is rapidly increased with the shear strain rate, to generate a great resistance force, thereby preventing the fault from further slipping. |

Described are very high molecular weight (e.g., over 2 million, such as 3-20 million g/mol) starch-based materials, and formulations including such, which can be spun in spunbond, melt blown, yarn, or similar processes. Even with such very high molecular weights, the formulations can be processed at commercial line speeds, with spinneret shear viscosities of 1000 sec−1, without onset of melt flow instability. The starch-based material can be blended with one or more thermoplastic materials having higher melt flow index value(s), which serve as a diluent and plasticizer, allowing the very viscous starch-based component to be spun under such conditions. The particular melt flow index characteristics of the thermoplastic diluent material can be selected based on what type of process is being used (e.g., spunbond, melt blown, yarn, etc.). The starch-based material may exhibit high shear sensitivity, strain hardening behavior, and/or very high critical shear stress (e.g., at least 125 kPa). |
