Disclosed herein are example embodiments of an improved narrative generation system where an analysis service that executes data analysis logic, including data re-organization logic, that supports story generation is segregated from an authoring service that executes authoring logic for story generation through an interface. Accordingly, when the authoring service needs analysis from the analysis service, it can invoke the analysis service through the interface. By exposing the analysis service to the authoring service through the shared interface, the details of the logic underlying the analysis service are shielded from the authoring service (and vice versa where the details of the authoring service are shielded from the analysis service). Through parameterization of operating variables, the analysis service can thus be designed as a generalized data analysis service that can operate in a number of different content verticals with respect to a variety of different story types.

A hierarchy of interconnected memory retention (MR) circuits detect a clock gating mode being entered at any level of an integrated circuit. In response, the hierarchy automatically transitions memory at the clock gated level and all levels below the clock-gated level from a normal operating state to a memory retention state. When a memory transitions from a normal operating state to a memory retention state, the memory transitions from a higher power state (corresponding to the normal operating state) to a lower power state (corresponding to the memory retention state). Thus, in addition to the dynamic power savings caused by the clock gating mode, the hierarchy of MR circuits automatically transitions the memory modules at the clock gated level and all levels below the clock gated level to a lower power state. As a result, the leakage power consumption of the corresponding memory modules is reduced relative to prior approaches.

In an overload state, ratcheting is generated in the strain wave gearing, so that the strain wave gearing functions as a mechanical fuse. Other power transmission members can be protected from an overload state without adding a separate member such as a torque limiter.

The method of producing lithium titanate anode material for lithium ion battery applications is comprising of: a) mixing of mixed phase having 60-80% anatase and 20-40% rutile of TiO2 as titanium precursor with Li2CO3 as lithium precursor in a stoichiometric ratio of 5:4 and adding with 2 to 5% stearic acid as process control agent as well as carbon precursor; b) milling in horizontal attrition milling unit maintained with the ball to powder ratio of 10:1-12:1 at 250-500 rpm for 0.5 to 2 hrs c) repeating the milling for 40 to 48 times; d) palletisation of the milled powder to a diameter of 30-35 mm under a pressure of 0.5-1 ton; e) annealing under inert atmosphere at a temperature of 700-900° C. for a period of 2-12 hrs; and f) grinding the resultant annealed composite powder to a fine powder. Resultant powder has shown excellent electrochemical properties in terms of charge-discharge, cyclic-stability and rate capability.

The copper oxide nanoparticles synthesized using Rhatany root extract involves preparing the Rhatany root extract by adding powdered Rhatany roots to boiling water, allowing the mixture to soak overnight, and removing any solid residue by filtering to obtain the aqueous extract. The copper oxide nanoparticles are prepared by mixing equal volumes of the aqueous Rhatany root extract and 0.1 M aqueous copper sulfate, heating the mixture at 80° C. for 40 minutes, and adding 1 M sodium hydroxide dropwise to the mixture to precipitate CuO. The precipitate is removed by centrifuge, washed with ethanol, dried, and calcined at 400° C. for 4 hours to obtain the copper oxide nanoparticles. The resulting nanoparticles proved effective in degrading wastewater dyes, showed anticancer activity against human cervical cancer by cell viability assay, and showed antibacterial activity against various strains of bacteria by agar diffusion.

A family of new crystalline molecular sieves designated SSZ-91 is disclosed, as are methods for making SSZ-91 and uses for SSZ-91. Molecular sieve SSZ-91 is structurally similar to sieves falling within the ZSM-48 family of molecular sieves, and is characterized as: (1) having a low degree of faulting, (2) a low aspect ratio that inhibits hydrocracking as compared to conventional ZSM-48 materials having an aspect ratio of greater than 8, and (3) is substantially phase pure.
