    Abstract: In some embodiments, an apparatus includes providing a representation of a set of digital medical images to a first machine learning model to define a feature vector associated with a presence of an intracranial hemorrhage. A representation of the set of digital medical images is provided to a second machine learning model to define a second feature vector associated with a volume of the intracranial hemorrhage. Using a third machine learning model, a set of EMRs associated with risk factors for a predefined indication is analyzed to define a third feature vector. The first, second and third feature vectors are provided as inputs to a fourth machine learning model to determine a metric associated with an applicability of a specific treatment associated with a predefined indication. An alert is sent to relevant healthcare providers and relevant tests, procedures or bloodwork are ordered for the predefined indication.

    Abstract: A method of elliptic curve encryption includes, (a) selecting an elliptic curve Ep (a,b) of the form y2=x3+ax+b mod (p) wherein a and b are non-negative integers less than p satisfying the formula 4 a3+27b2 mod (p) not equal to 0; (b) generating a large 160 bit random number by a method of concatenation of a number of smaller random numbers; (c) generating a well hidden point G (x,y) on the elliptic curve Ep (a,b) by scalar multiplication of a point B (x,y) on the elliptic curve with a large random integer which further includes the steps: (i) converting the large random integer into a series of powers of 231; (ii) converting each coefficient of 231 obtained from above step into a binary series; (iii) multiplication of binary series obtained from steps (i) and (ii) above with the point B (x,y) on the elliptic curve; (d) generating a private key nA (of about >=160 bit length); (e) generating a public key PA (x,y) given by the formula PA (x,y)=(nA−G (x,y)) mod (p); (f) encrypting the input message MSG; (g) decrypting the ciphered text.

    Abstract: A system for and method of electromagnetically detecting an embedded dielectric region within a target object are provided. The method includes the steps of: (i) selecting a target object including a plurality of discrete scattering mediums, wherein the plurality of discrete scattering mediums include the embedded dielectric region and an adjacent dielectric region, and wherein the plurality of discrete scattering mediums define at least one dielectric interface between the embedded dielectric region and the adjacent dielectric region; (ii) directing electromagnetic radiation at the target object, wherein the electromagnetic radiation is characterized by a diagnostic frequency that is varied incrementally over a diagnostic frequency band; (iii) detecting electromagnetic radiation reflected by the target object over the predetermined frequency band such that there are M measurements of a reflected electromagnetic signal at frequencies f.sub.1, f.sub.2, . . . , f.sub.N, where M represents a number of scattering mediums within the target object and where N represents a number of diagnostic frequencies within the diagnostic frequency band; (iv) constructing a correlation matrix representative of the reflected signal, wherein the correlation matrix comprises a number of signal eigenvectors and a number of noise eigenvectors; (v) decorrelating the correlation matrix by dividing the reflected signal according to frequency sub-bands within the diagnostic frequency band, wherein adjacent bands of the frequency sub-bands overlap, forming a series of iterated correlation matrices using signal eigenvectors and noise eigenvectors from each of the overlapping frequency sub-bands, forming a decorrelated matrix by averaging the iterated correlation matrices, wherein the decorrelated matrix comprises a finite group of signal eigenvectors and a finite group of noise eigenvectors; and (vi) constructing a scattering signature of the target object from the finite group of signal eigenvectors, wherein the scattering signature is indicative of the properties of the embedded dielectric region and the adjacent dielectric region.
