Abstract: A system and method for engineering loss in a physical system by steering parameters of the physical system to the vicinity of an exceptional point is disclosed. In the vicinity of an exceptional point, localization of the fields helps to enhance any linear or nonlinear processes. As examples loss-induced transparency in the intracavity field intensities of coupled resonators, loss-induced suppression and enhancement of thermal nonlinearity in coupled resonators and loss-induced suppression and revival of Raman lasing in whispering-gallery-microcavities are demonstrated.

Abstract: The invention encompasses a method for amplifying at least two different nucleic acid sequences. In particular, the method encompasses a multiplexed nucleic acid patch polymerase chain reaction.
Abstract: Disclosed herein are surgical suture materials that facilitate the sustained delivery of releasable components. The suture materials are processed by the disclosed methods to create a layer of pores extending inward from the outer surface of the suture. Particularly, the surgical suture materials are swollen in a calcium-ion containing solution, then freeze-dried to create pores which can be filled with a releasable component for ultimate delivery to the tissue. In one particular embodiment, the suture has an outer sheath that defines a lumen. Elongated filaments extend through the lumen. This suture embodiment is processed by the disclosed methods to yield a surgical suture material with a porous outer sheath. The pores enable efficient loading of a releasable component into the lumen, facilitating sustained delivery of the releasable component from the suture.

Abstract: A computer-implemented method for correcting artifacts within CT images of a subject includes providing iteratively correcting a CT volumetric image with a high-contrast mask by overpainting the high-contrast mask within CT volumetric image set by evaluating a model function and updating the CT projections to reflect the overpainting using a gradient descent based on previous overpainted CT projections, back-projecting the corrected CT projections to produce a corrected volumetric image set, and comparing the corrected CT volumetric image set against a previous corrected CT volumetric image set until convergence. The original voxels overpainted by the high-contrast mask are re-inserted into the converged CT volumetric image to produce the final CT volumetric image set.
Abstract: The present invention relates, inter alia, to a method comprising administering to a subject having high output shock and undergoing treatment with a catecholamine at a dose equivalent to at least about 0.2 mcg/kg/min of norepinephrine a dose of angiotensin II which is effective to raise the blood pressure of the subject to a mean arterial pressure (MAP) of about 6.5 mm Hg or above, and which is effective to reduce the dose of the catecholamine required to maintain a MAP of about 65 mm Hg to the equivalent of about 0.05-0.2 mcg/kg/min norepinephrine or less, or to the equivalent of about 0.05 mcg/kg/min norepinephrine or less.
