Abstract: Monocyclic chlorine based inductively coupled plasma deep etching processes for the rapid micromachining of titanium substrates and titanium devices so produced are disclosed. The method parameters are adjustable to simultaneously vary etch rate, mask selectivity, and surface roughness and can be applied to titanium substrates having a wide variety of thicknesses to produce high aspect ratio features, smooth sidewalls, and smooth surfaces. The titanium microdevices so produced exhibit beneficially high fracture toughness, biocompatibility and are robust and able to withstand harsh environments making them useful in a wide variety of applications including microelectronics, micromechanical devices, MEMS, and biological devices that may be used in vivo.

Abstract: An (Al, Ga, In)N and ZnO direct wafer bonded light emitting diode (LED), wherein light passes through electrically conductive ZnO. Flat and clean surfaces are prepared for both the (Al, Ga, In)N and ZnO wafers. A wafer bonding process is then performed between the (Al, Ga, In)N and ZnO wafers, wherein the (Al, Ga, In)N and ZnO wafers are joined together and then wafer bonded in a nitrogen ambient under uniaxial pressure at a set temperature for a set duration. After the wafer bonding process, ZnO is shaped for increasing light extraction from inside of LED.

Abstract: Assays for the detection of diabetes and prediabetic status rely on exposing patient serum samples to purified ligand capable of binding autoantibodies specific for a 64kD autoantigen present on pancreatic ?-cells. The purified ligand is usually purified glutamic acid decarboxylase (GAD) or a fragment or analog thereof. Preferably, the assays will detect the presence of antibodies to both lower molecular weight GAD and higher molecular weight GAD since diabetic and prediabetic status may be associated with only one of these two forms. The assays can be performed using conventional protocols, such as radioimmunoassay, enzyme-linked immunosorbent assay, and enzyme assay. Methods for treating diabetes comprise administering pharmaceutical compositions including the purified ligand, particularly when coupled to an immunoglobulin or lymphoid cell to induce tolerance.

Abstract: A system and apparatus for controlled fusion in a field reversed configuration (FRC) magnetic topology and conversion of fusion product energies directly to electric power. Preferably, plasma ions are magnetically confined in the FRC while plasma electrons are electrostatically confined in a deep energy well, created by tuning an externally applied magnetic field. In this configuration, ions and electrons may have adequate density and temperature so that upon collisions they are fused together by the nuclear force, thus forming fusion products that emerge in the form of an annular beam. Energy is removed from the fusion product ions as they spiral past electrodes of an inverse cyclotron converter. Advantageously, the fusion fuel plasmas that can be used with the present confinement and energy conversion system include advanced (aneutronic) fuels.

Abstract: A modest (2-5 fold) increase in androgen receptor (AR) mRNA is the only expression change consistently associated with developing resistance to antiandrogen therapy. Increased levels of AR confer resistance to anti-androgens by amplifying signal output from low levels of residual ligand and altering the normal response to antagonists. This invention provides cell based assays for use in the examination of new therapeutic modalities and provides for the design of novel antiandrogen compounds.

Abstract: Electroporation is performed in a controlled manner in either individual or multiple biological cells or biological tissue by monitoring the electrical impedance, defined herein as the ratio of current to voltage in the electroporation cell. The impedance detects the onset of electroporation in the biological cell(s), and this information is used to control the intensity and duration of the voltage to assure that electroporation has occurred without destroying the cell(s). This is applicable to electroporation in general. In addition, a particular method and apparatus are disclosed in which electroporation and/or mass transfer across a cell membrane are accomplished by securing a cell across an opening in a barrier between two chambers such that the cell closes the opening. The barrier is either electrically insulating, impermeable to the solute, or both, depending on whether pore formation, diffusive transport of the solute across the membrane, or both are sought.

Abstract: A system and method for filtering unwanted Internet Protocol traffic based on blacklists receives a first blacklist containing a first plurality of Internet protocol addresses associated with unwanted Internet traffic. The system also operates a first plurality of access control lists adapted to block the unwanted Internet traffic from one of the first Internet protocol addresses listed in the first blacklist. The system also assigns a first weight to each of the first Internet protocol addresses based on a reliability of Internet traffic from each of the first Internet protocol addresses. Additionally, the system reduces a first number of the first access control lists to optimally trade off a number of desirable Internet protocol addresses blocked with a number of bad Internet protocol addresses blocked based on the first weight of each of the first Internet protocol addresses.
