The present invention provides methods and system for managing neurological disorders such as epilepsy. In one embodiment, the method comprises measuring one or more signals from a patient and processing the one or more signals to characterize a patient's propensity for a future seizure. The characterized propensity for the seizure is thereafter used to determine an appropriate action for managing or treating the predicted seizure; and a recommendation is communicated to the patient that is indicative of the appropriate action.

The present invention provides systems and methods for managing epilepsy. In one embodiment, a method of the present invention characterize a patient's propensity for a future epileptic seizure and communicates to the patient and / or a health care provider a therapy recommendation. The therapy recommendation is typically a function of the patient's propensity for the future epileptic seizure.

The composition for forming silica based coating of the invention comprises siloxane resin such as an alkoxysilane as component (a), a solvent such as an alcohol capable of dissolving the siloxane resin as component (b), an ammonium salt, etc. as component (c) and a thermal decomposing / volatile compound as component (d), wherein the stress of the coating obtained by heat treatment at 150° C. / 3 min is 10 MPa and the specific permittivity of the silica based coating obtained by final curing is less than 3.0. The composition for forming silica based coating according to the invention can form a silica based coating having low permittivity, excellent adhesion and sufficient mechanical strength.

Cementing compositions for use in oilfield applications are designed such that, after setting, a significant amount of cement remains unhydrated. After placement in a subterranean well, the unhydrated cement remains dormant. If the cement sheath becomes damaged, the unhydrated cement hydrates upon exposure to formation fluids, thereby restoring zonal isolation in the wellbore. The compositions comprise emulsions that allow a substantial reduction of the water-to-cement ratio, yet the rheological properties remain suitable for placement in the well.

The invention belongs to the technical field of automotive linings and discloses a material having bactericidal and peculiar smell removing functions and used for automotive linings. The material for the automotive linings is made from, by weight, 100-120 parts of isotactic polypropylene, 8-16 parts of maleic anhydride grafted polypropylene, 8-16 parts of medical stone, 3-5 parts of lanthanum-supportedzinc oxide, 3-5 parts of cerium-supported titanium dioxide, 0.3-0.5 part of antioxidant, 8-16 parts of vermiculite, 0.6-1 part of silane coupling agent, 0.2-0.4 part of monoglyceride, 30-50 parts of polyethylene wax, 20-30 parts of chitin fiber, 30-50 parts of carbon nanofiber, 30-40 parts of bamboo fiber, 4-6 parts of perilla oil, 10-20 parts of gardenia, 8-16 parts of bamboo shavings, 10-20 parts of magnolia officinalis, 6-12 parts of emblic leafflower leaves and 15-25 parts of prunella vulgaris. The material for the automotive linings has strong bactericidal ability and can play long-term bactericidal and peculiar smell removing effects and a good bacteriostatic effect.
