Abstract: A method is performed by a network controller that is configured to control routers configured to forward a multicast flow downstream from a first hop router that is a root of a multicast tree formed by the routers to last hop routers that terminate branches of the multicast tree, respectively. The method includes collecting operational configuration information from the routers and constructing a topological view of the multicast tree based on the operational configuration information; causing the routers to forward multicast probes downstream from the first hop router along all of the branches toward the last hop routers to trace the multicast tree; receiving, from particular ones of the last hop routers that received the multicast probes, indications that the multicast probes were received; and detecting failures in the multicast tree based on the indications and the topological view.

Abstract: Disclosed systems, methods, and computer readable media can diagnose a health condition based on patient time series data. For example, a method for diagnosing a health condition based on patient time series data includes identifying a training set of health records comprising a first set of patient time series data, training a neural network using the training set of health records, and executing the trained neural network model to diagnose a health condition based on a second set of patient time series data. In further examples, the first set of patient time series data and the second set of patient time series data can each comprise electrocardiogram data and the health condition can comprise pulmonary hypertension.

Abstract: A novel macroscale, contactless, label-free method to print in situ three-dimensional (3D) particle assemblies of different morphologies and sizes is demonstrated using non-adherent (blood) and adherent (MCF-7 and HUVEC) cells. This method of manipulating particles such as cells or biological moleules does not necessarily require the use of nozzles that can contaminate the cell suspension, or to which cells can adhere. Instead, the intrinsic diamagnetic properties of particles such as cells are used to magnetically manipulate them in situ in a nontoxic paramagnetic medium, creating various shapes such as (a) rectangular bar, (b) three-pointed star, and (c) spheroids of varying sizes. A normal distribution of 3D cell structures is produced when formed through magnetic assembly. The use of this method in co-culturing of different cell lines is also demonstrated.

Abstract: A method of implementing a mobility as a service policy may include associating an identifier with a mobility service policy. The method may include assigning the mobility service policy to at least one mobility service provider of a plurality of mobility service providers. The method may include setting at least one usage restriction for the mobility service policy. The at least one usage restriction may limit operation of the at least one mobility service provider when the policy is activated. The method may include setting a geographical restriction associated with the mobility service policy. The method may include setting a time restriction associated with when the mobility service policy is to be active. The method may include enabling the mobility service policy.

Abstract: This invention discloses a method of accurately detecting the current bit in a SDPSK modulated signal at the receiver. The proposed method calculates the current bit from the past-detected bits and the past symbols. Each past symbol estimates the current bit. Each of these estimates is summed up to provide the final estimate of the bit. The proposed method for the reception of SDPSK modulated data improves the bit error rate performance. The proposed method can be applied in any communication system that uses SDPSK modulation.

Abstract: The present invention provides a method of accurately determining the signal to noise ratio (SNR) using filters. Three embodiments of the invention are disclosed: the use of fixed filters, multiple filters and dynamic filters. The total noise energy is calculated by applying low pass and high pass filters. The minimum of the two noise energies estimated by the low pass and high pass filters is selected to calculate the total noise energy in the signal. The present invention provides an accurate method of SNR estimation in conditions of low SNR and high carrier offsets, without the requirement for bringing the signal to base band. The use of multiple filters provides accurate SNR measurement even in the presence of discrete interferences.
