Abstract: For a given application, increasing the size of a cache is beneficial up to a certain point and the number of hits does not increase significantly with a greater cache size. This disclosure provides a method to determine a miss ratio curve, for a cache having data blocks with a time-to-live. A hashed value of a data block's key address can be used to generate a 2D HLL counter for storing expiry times of the data blocks. The 2D HLL counter can be converted to a 1D array, from which a stack distance can be calculated. A frequency distribution of stack distances can then be converted into a miss ratio curve, from which an appropriate cache size can be selected.

Abstract: Custom-form batteries can supply complex, practical systems with an optimal energy density that wouldn't otherwise be possible using traditional battery form-factors. For example, iron disulfide (FeS2) is a prominent conversion cathode of commercial interest. 3D direct-ink write (DIW) printing of FeS2 inks can be used to produce ridged cathodes from the filamentary extrusion of highly concentrated FeS2 inks (60-70% solids). These ridged cathodes exhibit optimal power, uniformity, and stability when cycled at higher rates (in excess of C/10). Meanwhile, functional cells with custom-form wave-shaped electrodes (e.g., printed FeS2 cathodes and pressed lithium anodes) exhibit improved performance over similar cells in planar configurations. In general, the DIW of concentrated inks is a viable path toward the making of custom-form conversion lithium batteries. More broadly, ridging is found to optimize rate capability.
