  • Publication number: 20220415319
    Abstract: Implementations described herein relate to generating, locally at a client device, corresponding subset(s) of zero-prefix suggestions, for a user of the client device, and for suggestion state(s) associated with the client device, and subsequently causing the client device to utilize the corresponding subset(s) of zero-prefix suggestions. The suggestion state(s) and a superset of candidate zero-prefix suggestions can be processed, using machine learning model(s), to generate a corresponding score for each of the candidate zero-prefix suggestions and with respect to the suggestion state(s). Further, zero-prefix suggestions can be selected for inclusion in the corresponding subset(s) of zero-prefix suggestions, and for the suggestion state(s), based on the corresponding scores.

  • Publication number: 20220007669
    Abstract: A method for making tea cubes containing a blend of granular sugar, dry extract of either black or green teas, micronized tea and flavour comprises providing tea leaves that have been micronized in a jet mill (1) to simulate performance of instant tea without contributing any stickiness. Next, sugar and flavour are prepared for mixing and incorporating them with micronized tea. The particle size distribution of sugar is decided depending upon the percentage (%) of non-sugar ingredients in the cube formulation.

  • Publication number: 20170058319
    Abstract: Constructs and monitoring systems to assess the level of molecules that bind to thrombin (e.g. thrombin regulators and inhibitors) are provided. The constructs are nanosensors comprising i) a thrombin molecule to which is bound a reporter ligand comprising a fluorescent label, ii) a fluorescence-quenching metal nanoparticle, and, optionally iii) a fluorescence-quenching dye molecule attached to one or both of the nanoparticle and the thrombin molecule. The binding of a thrombin regulator or inhibitor to the thrombin molecule displaces the reporter ligand, and the signal from the fluorescent label increases. The increase is proportional to the concentration of thrombin-binding molecule in the sample.

  • Publication number: 20160201112
    Abstract: High sensitivity nanosensors for detecting the inhibition of glycosaminoglycan (GAG)-cleaving enzymes are provided. Methods of using the nanosensors include detecting contaminants in commercial GAG preparations (e.g. heparin preparations) by measuring the activity levels of a GAG)-cleaving enzyme in the presence of a sample which may contain a contaminant that inhibits the GAG-cleaving enzyme.

  • Patent number: 8262881
    Abstract: Methods to generate a distinctive fingerprint (pattern of migration) for a sample of complex, polydisperse heparins are provided. The methods involve adding resolving agents such as polyamines to a heparin sample and then analyzing the sample with a technique that separates macromolecules according to charge to mass ratio (e.g. capillary electrophoresis). The resulting electropherogram is unique to and characteristic of the heparin sample. The methods may be used, for example, to monitor the quality and consistency of various heparin preparations.

  • Publication number: 20110060578
    Abstract: An agent-based modeling system (ABMS) is employed to quantitatively analyze individual components of each system of the coagulation-immune/inflammatory-fibrinolysis system at every point of simulation. ABMS is a dynamic modeling and simulation tool that allows the study of dynamic non-linear networked systems. ABMS represents a non-reductionist approach of studying the biologic process as a whole, while retaining information at the level of an individual component.
