Abstract: The present application provides a system and method for using a nuclear magnetic resonance (NMR) system. The method includes performing a pulse sequence using the NMR system that spatially encodes NMR signal evolutions to be acquired from a subject using an aggregated radio-frequency (B1) field incoherence and resolving the NMR signal evolutions acquired from the subject using at least one of a dictionary of known magnetic resonance fingerprinting (MRF) signal evolutions to determine matches in the NMR signal evolutions to the known MRF signal evolutions or an optimization process.

Abstract: The present disclosure is directed to the use of left-handed DNA (L-DNA) tracer to identify the source, track the distribution, and validate the integrity of products or resources that are highly regulated, valuable, or hazardous (e.g., pharmaceuticals, treated water, chemicals, designer products, and ammunitions). L-DNA tracers can encrypt unique identifying information, as well as more general information about the type of product, such as the manufacturing location, source, and date, directly into the nucleotide sequence. The L-DNA tracers can embed directly into the product so that it could neither be disassociated from the product nor be re-associated with another product. Because there are no technologies available to sequence L-DNA, the L-DNA tracers cannot be reverse engineered, copied, or falsified. The L-DNA tracers are only deciphered using a unique detection key.

Also disclosed herein is a method of cleaving the cleavable agent for enhanced magnetic resonance.

Abstract: Imaging methods for assessing the macromolecular content, such as myelin, are of great interest for understanding brain tissue microstructure, and have shown potentials in diagnosing and prognosing demyelinating diseases. for example. Magnetization transfer (MT) is a MRI contrast mechanism that enables detection of macromolecules. Previously, the MT effect has been analyzed by a semi-quantitative method termed magnetization transfer ratio (MTR) or by a quantitative magnetization transfer (qMT) method. However, because MTR does not have enough sensitivity and specificity to myelin, and qMT takes a very long scan time, their translation into clinical scenarios has been limited. This disclosure describes a MT data analysis metric using double saturation pulse offsets and powers (dopMTR).

Abstract: A 2D spatial differentiator operates in transmission and comprises a Si nanorod photonic crystal that can transform an image, Ein, into its second-order derivative, Eout ? ?2 Ein, allowing for direct discrimination of the edges in the image. The use of a 2D photonic crystal allows for differentiation and edge detection in all directions with a numerical aperture (NA) up to 0.315 and an experimental resolution smaller than 4 ?m. The nanophotonic differentiator is able to be directly integrated into an optical microscope and onto a camera sensor, demonstrating the ease with which it can be vertically integrated into existing imaging systems. Furthermore, integration with a metalens is demonstrated for realizing a compact and monolithic image-processing system. In all cases, the use of the nanophotonic differentiator allows for a significant reduction in size compared to traditional systems, opening new doors for optical analog image processing in applications involving computer vision.

Abstract: A steerable endoscope system includes a continuum manipulator, a plurality of syringes, and a steerable tip. The continuum manipulator includes a plurality of spaced discs and a plurality of backbones each extending through all discs. A bending movement of the continuum manipulator changes a varying linear displacement of each backbone. Each backbone is further coupled to a different one of the syringes such that the linear displacement of each backbone pushes or pulls a piston of the corresponding syringe by a varying amount. The steerable tip includes a plurality of bellows each pneumatically coupled to a different syringe such that movement of the piston of a syringe causes the corresponding bellow to inflate or deflate. Because the distal end of each bellow is fixedly coupled to the same end effector, variations in the amount of inflation or deflation on each bellow causes a bending of the steerable tip.
