Abstract: Systems and methods are provided for encoding information as the pattern of the lengths of RNA tails (or other tail biomolecules, e.g., polypeptides) attached to a dsDNA (or other backbone biomolecule) and the relative locations of attachment thereto. This information can be quickly and accurately read out by passing such information-encoding payload biomolecules through a nanopore and detecting the pattern of conductance of the pore (e.g., the ionic conductance through the pore and/or the transverse conductance of the membrane bearing the pore) as the payload passes therethrough. The conductance can be processed by subtracting a time-varying correction factor therefrom that represents the expected conductance for a ‘tail-free’ backbone as it transits through the pore, by applying a time-varying velocity factor that is dependent on the number of tails present in the pore over time to normalize individual tail dwell times, and/or other processing steps.

Abstract: Provided are implantable probes for analyzing biological fluids and related methods of using and making. The probe is formed with an integrated on-chip probe body that provides for collection and storage of analyte from biological fluid and facilitates subsequent analysis, including by a mass spectrometer (MS). The analysis has high spatial accuracy as the probe tip that collects biological fluid sample is small, including less than 100 ?m with an opening less than 10 ?m. Temporal information can be obtained by storing the analyte from the biological fluid as a train of droplets separated by an immiscible fluid. The probe body can be electrically energized to facilitate sample ionization and transfer to a MS analysis device. In this manner, the integrated on-chip probe body facilitates analyte collection, storage and subsequent analysis within a single probe body material, including a doped silicon material.

Abstract: A densely integrated and chiplet/dielet based networked memory pool with very high intra-pool bandwidth is provided. Chiplets are used to provide a common interface to the network. This means all memories (even those built with different process technologies) look the same from the network's perspective and vice versa: memory can be assembled in many different configurations while only changing the configuration at a high level of abstraction. The memory pool can easily be scaled in capacity and custom configurations that were previously impossible to achieve because of incompatibility of different technologies or level of integration are made possible.

Abstract: New synthetic methods to provide access to previously unexplored functionality at the C8 position of substituted imidazo[5,1-d][1,2,3,5]tetrazines of Formula I. Through synthesis and evaluation of a suite of compounds with a range of aqueous stabilities (from 0.5 to 40 hours), a predictive model for imidazotetrazine hydrolytic stability based on the Hammett constant of the C8 substituent was derived. Promising compounds were identified that possess activity against a panel of GBM cell lines, appropriate hydrolytic and metabolic stability, and brain-to-serum ratios dramatically elevated relative to TMZ, leading to lower hematological toxicity profiles and superior activity to TMZ in a mouse model of GBM.
