Abstract: A method of detecting the length of an individual telomere is provided. In one embodiment, the method includes contacting genomic DNA with a guide RNA having a portion complementary to a telomere repeat sequence in the genomic DNA and with Cas9 nickase to produce a single-strand break in the genomic DNA at the telomere repeat sequence. The nicked DNA is contacted with a polymerase and fluorescently labeled nucleotide, wherein the fluorescently labeled nucleotide is incorporated into the nicked DNA at the telomere repeat sequence. The genomic DNA is contacted with a second nicking endonuclease which is specific for a sequence motif in the genomic DNA thereby producing a second nick in the genomic DNA at the motif sequence. The nicked DNA is contacted with a polymerase and second fluorescently labeled nucleotide of different color, wherein the second fluorescently labeled nucleotide is incorporated into the nicked DNA at the motif sequence location.

Abstract: There are provided systems and methods for a multi-layer cache to prevent user experience interrupts during feature flag management. A service provider may provide applications to computing devices of users including mobile applications. Use and availability of features in an application may be configured using feature flags, however, change of these feature flags may initiate an application refresh that affects user experiences with the application. To prevent interruptions, a multi-layer data cache may be used where feature flag data for the feature flags may initially be loaded, after a time period, to a first layer cache that is not used to update the application. When conditions exist for updating the application without affecting the user experience, such as if the user is no longer using a workflow, the feature flag data may be loaded to a second layer cache. The second layer cache may then be used for updating.

Abstract: Exemplary embodiments relate to techniques for determining structural color from parameters of an array of nanopartides. The techniques include inputting structural and optical parameters and performing a probabilistic simulation to determine the structural color. An evolutionary optimization may be performed to determine parameters of the array of nanoparticles according to desired properties of structural color. The evolutionary optimization may employ the probabilistic simulation and further adjust one or more parameters of the array to approximate the desired properties of the structural color. Based on applying the probabilistic simulation, the technique may generate an output describing a value, or a range of values, for the one or more parameters of the array of nanoparticles that are selected to approximate the desired properties of the structural color.
