Abstract: A concentric tube steerable device includes a plurality of tubes having a nested, concentric configuration. The tubes include an outer tube and an inner tube that extends coaxially within the outer tube. The inner tube terminates at a tip, and a pose of the tip is effectuated through individual or collective rotation or translation of the tubes about a tube axis. The concentric tube steerable device includes an actuator for rotating at least one tube about a respective tube axis, and a translator for translating at least one tube along a respective tube axis. Each tube includes a precurved portion and a corresponding axis of precurvature. For at least one tube, a flexural rigidity of the tube along its axis of precurvature is less than a flexural rigidity of the tube along a second axis that is perpendicular to the axis of precurvature, thereby improving stability of the tube.

Abstract: In ultra-wideband or impulse radio terahertz wireless communication, the electromagnetic signal may experience group delay dispersion (GDD). Without correction, this can degrade the achievable data transmission rate. An apparatus comprising a stratified structure having a front portion and a back portion is disclosed. The structure comprises a plurality of adjacent layers of differing refractive indices, wherein each layer has a refractive index different from an immediately adjacent layer. The structure further includes a backing layer at the back portion. The structure defines a GDD, which can be adjusted, and the structure is configured to introduce the GDD to an incident electromagnetic signal and thereby produce a dispersion-compensated electromagnetic signal when the incident signal is reflected by the structure. The GDD of the structure is configured to substantially cancel out the dispersive effects experienced by the electromagnetic signal in the signal path.

Abstract: The present invention is based, in part, on our discovery that certain types of therapeutic agents can be used in combination to treat a variety of neuropsychiatric and related disorders, including addiction (e.g., to a substance or to an activity) as well as to alleviate some of the symptoms experienced during menopause or associated with the menstrual cycle. Regardless of the precise formulation, the compositions of the invention can include at least one active ingredient that targets the hypothalamopituitary-adrenal (HPA) axis and at least one active ingredient that targets the prefrontal cortex. Either or both of these types of agents can be combined with an agent that inhibits activity in the sympathetic nervous system. Thus, the compositions or combination pharmacotherapies can also include an agent that inhibits a beta-adrenergic receptor or that otherwise acts as an anti-hypertensive or anxiolytic agent.
