Abstract:
A fast and economical system and methods directed to low-fidelity fabrication of three-dimensional (3D) objects using 3D printing. The invention facilitates rapid prototyping by providing a wireframe structure in the form of the underlying design structure of a 3D model, which may be useful for a variety of reasons including to provide a prototype preview that may be used for design validation of a 3D model.
Abstract:
The present invention is directed to a method for identifying an individual who is at risk for developing metastatic liver disease that involves measuring, in a sample isolated from the individual, exosomal levels of one or more markers of metastatic liver disease. Kits for carrying out this method are also disclosed. The present invention also relates to a method of preventing metastatic liver disease in an individual who are at risk for developing the disease that involves administering one or more inhibitors of liver premetastatic niche formation.
Abstract:
The present invention is directed to methods for identifying the presence of one or more methylated or unmethylated target nucleotide sequences in a sample that involve coupled methylation sensitive restriction enzyme digestion-ligation and/or extension processes. In some embodiments, the ligation and primary extension products formed in the reaction processes of the present invention are subsequently amplified using a polymerase chain reaction. The ligation products or primary extension products are detected, and the presence of one or more methylated or unmethylated target nucleotide sequences in the sample is identified based on the detection.
Abstract:
Methods, systems, and devices are disclosed for divided-pulse lasers. In one aspect, a pulsed laser is provided to include a laser cavity including an optical amplifier and a plurality of optical dividing elements and configured to direct a laser pulse of linearly polarized light into the plurality of optical dividing elements to divide the light of the laser pulse into a sequence of divided pulses each having a pulse energy being a portion of the energy of the laser pulse before entry of the optical dividing elements, to subsequently direct the divided pulses into the optical amplifier to produce amplified divided pulses. The laser cavity is configured to direct the amplified divided pulses back into the plurality of optical dividing elements for a second time in an opposite direction to recombine the amplified divided pulses into a single laser pulse with greater pulse energy as an output pulse of the laser cavity.
Abstract:
The present invention relates to an artificial hip joint replacement system. The system includes an acetabulum portion comprising a cup suitable to be received by a subject's acetabular bone. The cup includes a rigid portion and an elastic portion attached to the rigid portion. Also included in the system is a ball received within the cup and in contact with the elastic portion and a femoral stem attached to the ball. The elastic portion is positioned to cause expansion and contraction of a space between the ball and the rigid portion of the cup so they are further apart from one another during periods of low mechanical loads.
Abstract:
A nanoparticle and a method for fabricating the nanoparticle utilize a decomposable material yoke located within permeable organic polymer material shell and separated from the permeable organic polymer material shell by a void space. When the decomposable material yoke comprises a sulfur material and the permeable organic polymer material shell comprises a material permeable to both a sulfur material vapor and a lithium ion within a battery electrolyte the nanoparticle may be used within an electrode for a Li/S battery absent the negative effects of battery electrode materials expansion.
Abstract:
The present invention relates to methods of treating or preventing drug poisoning and drug addiction in a subject. These methods involve administering to a subject in need of said treatment or prevention a ligand which binds to a regulatory site on the nicotinic acetylcholine receptor.
Abstract:
A floating gate based sensor apparatus includes at least two separate electrical bias components with respect to a floating gate based sensor surface within the floating gate based sensor apparatus. By including the at least two electrical bias components, the floating gate based sensor apparatus provides enhanced capabilities for biomaterial and non-biomaterial detection and manipulation while using the floating gate based sensor apparatus.
Abstract:
A nasal spray delivery guide including a pair of guide elements spaced apart from one another and configured to be at least partially inserted into respective nostrils of a patient, and a flexible connector element attached to and extending between the guide elements. Each guide element includes an aperture extending therethrough from a base end to a tip end of the guide element. A method for delivering a nasal spray into a patient's nose includes the steps of providing the nasal spray delivery guide, inserting the guide elements at least partially into respective nostrils of the patient, inserting at least a portion of a nasal spray delivery device into one of the guide elements, and activating the nasal spray delivery device to deliver a nasal spray to a lateral wall of the respective nasal cavity.
Abstract:
A method for preparing a material composition comprising a hollow transition metal oxide nanoparticle supported upon a carbon material support includes a solution impregnation process step, followed by a thermal reduction process step and finally a thermal oxidation process step. The material composition, an electrode and an electrical component such as but not limited to a battery are all predicated at least in-part upon the material composition prepared in accord with the foregoing method. The foregoing material composition, electrode, battery and method may ultimately provide a LIB with enhanced performance.
