Methods for determining the presence or absence of expansion of CGG repeat sequence in the FMR1 gene presence or absence of expansion of CCG repeat sequence in the FMR2 gene are provided. The methods are useful in identifying an individual with normal/intermediate, versus premutation or full mutation allele of FMR1 gene and FMR2 gene due to the expansion of CGG repeats and CCG repeats in the 5′-untranslated region respectively. The methods are also useful for screening newborns for fragile X syndrome or for screening women to determine heterozygosity status with full premutation of the CCG repeat tract. The methods are also useful in estimating the premutation and full mutation carrier frequency and estimating the prevalence of FXTAS AND FXPOI in a population. The methods are simple, rapid and require small amount of sample.

Some aspects of the present invention include a system for computationally prediction of oscillation patterns of charges in a DNA sequence. Such a system includes one or more means for computationally predicting proton wires with longitudinal (coaxial) hydrogen bonds in the DNA sequence; and at least one means for predicting electron wires in the DNA sequence. These wires connect the aromatic rings of DNA basepairs. The above system includes at least one means for predicting tautomeric oscillations in said DNA.

A method according to some aspects of the present invention for computationally predicting oscillation pattern of charges in a DNA sequence includes: computationally predicting proton wires containing longitudinal (coaxial) hydrogen bonds, the wires spanning at least two DNA basepairs; predicting electron wires in the DNA which includes stretches of purines; and predicting tautomeric oscillations in the DNA.

A method for investigating intra- and/or intermolecular interactions involving RNA is provided. The method includes a) synthesizing a RNA/DNA heteroduplex (RDH) comprising a RNA strand of interest paired to a DNA strand; b) binding a first end of the DNA strand and a corresponding first end of the RNA strand to a first element of a nanoscale manipulating device, and a second end of the DNA strand to a second element of the nanoscale manipulating device, leaving a second end of the RNA strand free; c) moving the first and second elements of the manipulating device apart from each other, stretching the DNA strand and causing the RNA strand to peel off the heteroduplex; and d) moving the first and second elements of the nanoscale manipulating device towards each other, allowing the DNA strand to relax and causing the RNA strand to bind again to it. Measurement of a force-displacement relationship during steps c) and d) provides information on intra- and/or intermolecular interactions involving the RNA strand. Also provided is an apparatus for carrying out the method.

Methods, devices, and systems are provided for quantifying an extent of various pathology patterns in scanned subject images. The detection and quantification of pathology is performed automatically and unsupervised via a trained system. The methods, devices, and systems described herein generate unique dictionaries of elements based on actual image data scans to automatically identify pathology of new image data scans of subjects. The automatic detection and quantification system can detect a number of pathologies including a usual interstitial pneumonia pattern on computed tomography images, which is subject to high inter-observer variation, in the diagnosis of idiopathic pulmonary fibrosis.

A synthetic, cognitive cell, system, and method for automatically generating an output based on an environmental input is disclosed. The cognitive cell includes an operator including chemical agents, and a coded chemical including polymers. Each of the polymers includes a sequence of affinity blocks of molecular groups arranged in predetermined patterns to define a multi-layered base code. Each of the affinity blocks includes a monomer with a sidechain, the sidechains having affinities to each other. At least a portion of the affinity blocks forming a gate switch defining a bridge between the environmental inputs and the chemical agent whereby, upon exposure to the environmental inputs, the gate switches trigger the chemical agent to perform an operation. The coded chemical and at least one chemical agent are contained within a natural or synthetic membrane.
