Abstract: A coating (626) comprising a ferroelectric, lossy dielectric, ferromagnetic or semiconductor material is disposed near an object (620). AC current flows through an electrical conductor (624), creating an electromagnetic field. The coating (626) absorbs energy from the electromagnetic field, thereby generating heat, which melts snow and ice on the object (620).

Abstract: A process is described for the production of decomposable soluble products from a slurry of solids in which the slurry is convey axially through the reactor and excess liquid is removed radially through the walls of the reactor. The primary example is the hydrolysis of lignocellulosic biomass to form sugars, usually using an acid catalyst. In one variation of the process liquid and possibly steam are added through the inner wall of the reactor to provide additional flow in the radial direction and to control the temperature. Pressures are maintained such that the product stream is thermally quenched due to partial flashing as it leaves the reactor.

Abstract: Isolated nucleic acid molecules encoding members of the MRT family of polypeptides which include, in a preferred embodiment, at least one transmembrane domain having at least about 30%, more preferably at least about 50%, 55%, 60%, 70%, 80% or 90% amino acid sequence identity with SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6, SEQ ID NO:8 or SEQ ID NO:14 and/or at least one histidine rich domain, are described. The MRT polypeptides of the invention are capable of transporting metals such as Fe(II), Cd, Co, Mn, Pb, Hg and Zn. Transgenic plants in which expression of an MRT polypeptide of the invention is altered are also described. These transgenic plants can be used to remove pollutants from soil or as nutritional supplements to treat iron- or zinc-deficiency. Antisense nucleic acid molecules, recombinant expression vectors containing nucleic acid molecules of the invention, and host cells into which the expression vectors have been introduced are also described.

Abstract: A first electrode layer and a second electrode layer cover the surface of an object. The electrode layers are separated by a relatively large interelectrode distance, usually not exceeding 10 mm. Conductive ice or liquid water fills the interelectrode space between the electrodes, providing electrical connection of the electrodes. A DC or a low-frequency AC voltage is applied across the electrodes. The applied voltage causes electrolysis of water molecules at the electrodes, resulting in generation of hydrogen and oxygen gas bubbles. Optionally, a DC power supply generates sparks that ignite a mixture of the hydrogen and oxygen gases.

Abstract: The invention includes system for modifying ice adhesion strength of ice adhered to an object. The system includes an electrode that is electrically insulated from the object and a DC source, e.g., a battery, coupled to the object and the electrode. The source generates a DC bias to an interface between the ice and the object when the ice completes the circuit. The object is conductive or is doped as a semiconductor so that the DC bias applies a voltage a voltage to the interface which modifies the ice adhesion strength selectively as compared to the ice adhesion strength with substantially zero bias voltage at the interface. The strength can be increased or decreased relative to its static state (i.e., the state without applied voltage). In this manner, ice such as ice on an aircraft wing can be removed with less work.

Abstract: A method to automatically and adaptively tune a leaky, normalized least-mean-square (LNLMS) algorithm so as to maximize the stability and noise reduction performance in feedforward adaptive noise cancellation systems. The automatic tuning method provides for time-varying tuning parameters &lgr;k and &mgr;k that are functions of the instantaneous measured acoustic noise signal, weight vector length, and measurement noise variance. The method addresses situations in which signal-to-noise ratio varies substantially due to nonstationary noise fields, affecting stability, convergence, and steady-state noise cancellation performance of LMS algorithms. The method has been embodied in the particular context of active noise cancellation in communication headsets. However, the method is generic, in that it is applicable to a wide range of systems subject to nonstationary, i.e., time-varying, noise fields, including sonar, radar, echo cancellation, and telephony.

Abstract: Proinsulin peptide compounds that modulate an immunological response by T cells of Type I diabetic subjects are disclosed. The proinsulin peptide compounds of the invention are preferably derived from a region of proinsulin that spans the junction between the B chain and C peptide of proinsulin. Pharmaceutical compositions comprising the proinsulin peptide compounds are also disclosed. An immunological response to a proinsulin peptide compound of the invention can be used as an indicator of Type I diabetes in a subject. Accordingly, the invention provides diagnostic assays for Type I diabetes using the proinsulin peptide compounds. Methods for inhibiting the development or progression of Type I diabetes in a subject by administering a proinsulin peptide compound are also disclosed.

Abstract: A method is disclosed of lowering plasma levels of &agr;-dicarbonyl precursors of advanced glycation end-products, such as methylglyoxal, in a patient having type 2 diabetes by administrating metformin in a dosage from twenty-five to fifty percent in excess of its antidiabetic therapeutic regimen. The high dosage of metformin acts to reduce plasma levels of &agr;-dicarbonyl compounds by a mechanism distinct from that whereby it exerts its antidiabetic activity.

Abstract: The invention provides systems, methods for 14 treatment, and occlusion of the fallopian tube. An elongated catheter (22) is placed into the isthmic region (14) of the fallopian tube (16) in a trans-cervical trans-uterine fashion, and a mono-pole antenna (92) is disposed within a distal end of the catheter. The antenna radiates microwave energy in resonance to a drive frequency into tissue of the isthmic region without physical contact between the mono-pole antenna, and the tissue. This heating causes occlusion after a period of time. Typically, the catheter, and the mono-pole antenna are disposable after one treatment. In the preferred embodiment, the antenna is formed from an extension of the inner conductor of a coaxial cable coupled to a microwave generator. A power control section (24) can be used to control, and apply the appropriate microwave power to the fallopian tube tissue.

Abstract: Methods for inducing T cell tolerance to a tissue or organ graft in a transplant recipeint are disclosed. The methods involve administering to a subject: 1) an allogeneic or xenogeneic cell which expresses donor antigens and which has a ligand on the cell surface which interacts with a receptor on the surface of a recipient T cell which mediates contact-dependent helper effector function; and 2) an antagonist of the receptor which inhibits interaction of the ligand with the receptor. In a preferred embodiment, the allogeneic or xenogeneic cell is a B cell, preferably a resting B cell, and the molecule on the surface of the T cell which mediates contact-dependent helper effector function is gp39. A preferred gp39 antagonist is an anti-gp39 antibody. The allogeneic or xenogeneic cell and the gp39 antagonist are typically administered to a transplant recipient prior to transplantation of the tissue or organ.
