Abstract: An underwater diving marker is disclosed which has a tube with at least one removable end. A strap element extends between the removable end and the housing and is folding or otherwise compressed to fit within the housing. The end cap has a positive buoyancy so it will float when separated from the housing even with being attached to the strap. The housing includes a weight element which insures that the housing has a negative buoyancy when separated from the end cap. The user removes the end cap and allows it to float up pulling the strap/tether, while the housing sinks to the sea floor, thereby providing an indicator flag to divers.

Abstract: A molecular concentrator comprising a thermal ratchet for driving molecules from one place to another. A plurality of conducting wires are arranged on or suspended above a substrate. Each of the wires is configured to strongly sorb a vapor of interest when the wire is at room temperature and to rapidly desorb the vapor when the wire is at an elevated temperature. By selectively heating and cooling the wires, vapor molecules incident on the wires can be directed in a desired manner, e.g., from the wires closest to the vapor-containing environment to a sensor.

Abstract: A method includes covering ostai of branch vessels emanating from a main vessel and an aneurysm with an integrated mesh high metal to vessel ratio stent. The integrated mesh high metal to vessel ratio stent includes serpentine rings integrated with an integrated mesh having holes formed therein. A metal to vessel ratio of the integrated mesh high metal to vessel ratio stent is sufficiently high to encourage tissue ingrowth around the integrated mesh high metal to vessel ratio stent yet is sufficiently low to ensure perfusion of the branch vessels through the integrated mesh high metal to vessel ratio stent.

Abstract: A method of making a low-dimensional material chemical vapor sensor comprising exfoliating MoS2, applying the monolayer flakes of MoS2 onto a SiO2/Si wafer, applying a methylmethacrylate (MMA)/polymethylmethacrylate (PMMA) film, defining trenches for the deposition of metal contacts, and depositing one of Ti/Au, Au, and Pt in the trench and resulting in a MoS2 sensor. A low-dimensional material chemical vapor sensor comprising monolayer flakes of MoS2, trenches in the SiO2/Si wafer, metal contacts in the trenches, and thereby resulting in a MoS2 sensor. A full spectrum sensing suite comprising similarly fabricated parallel sensors made from a variety of low-dimensional materials including graphene, carbon nanotubes, MoS2, BN, and the family of transition metal dichalcogenides. The sensing suites are small, robust, sensitive, low-power, inexpensive, and fast in their response to chemical vapor analytes.

Abstract: A variable zone high metal to vessel ratio stent includes a proximal high metal to vessel ratio zone, a central low metal to vessel ratio zone, and a distal high metal to vessel ratio zone. The proximal high metal to vessel ratio zone is deployed with fixation and sealing to healthy tissue of a main vessel superior to branch vessels and an aneurysm. The central low metal to vessel ratio zone is deployed directly on ostai of the branch vessels. However, as the central low metal to vessel ratio zone is highly permeable, blood flows from the main vessel through the central low metal to vessel ratio zone and into branch vessels.

Abstract: A method includes covering an ostium of a branch vessel emanating from a main vessel with a proximal landing zone of a high metal to vessel ratio landing zone stent-graft, wherein a metal to vessel ratio of the proximal landing zone when deployed is sufficiently high to encourage tissue ingrowth around the proximal landing zone yet is sufficiently low to ensure perfusion of the branch vessel through the proximal landing zone. The method further includes covering an aneurysm of the main vessel with an exclusion zone of the high metal to vessel ratio landing zone stent-graft, the exclusion zone being formed of graft material. By forming the exclusion zone of graft material, excellent exclusion of the aneurysm is achieved.

Abstract: The disclosed subject matter describes a method, system, apparatus, and storage medium for interfacing multiple communication systems via a partitionable router. The router has at least two partitions, each partition having a subset of the router's resources allocated to it. Software programs are executed within each partition using their respective allocated resources. The resources, and any subset thereof, may be allocated non-exclusively, exclusively, and/or non-linearly to the partitions. The router receives information and determines the format of the information. The router identifies the receiving party and transforms the received information into a format compatible for the receiving party. The router then transmits the converted information to the receiving party, where the transmitting and/or receiving party is one of the software programs.
