Abstract: Implantable pressure-actuated systems to deliver a drug and/or other substance in response to a pressure difference between a system cavity and an exterior environment, and methods of fabrication and use. A pressure-rupturable membrane diaphragm may be tuned to rupture at a desired rupture threshold, rupture site, with a desired rupture pattern, and/or within a desired rupture time. Tuning may include material selection, thickness control, surface patterning, substrate support patterning. The cavity may be pressurized above or evacuated below the rupture threshold, and a diaphragm-protective layer may be provided to prevent premature rupture in an ambient environment and to dissipate within an implant environment. A drug delivery system may be implemented within a stent to release a substance upon a decrease in blood pressure. The cavity may include a thrombolytic drug to or other substance to treat a blood clot.

Abstract: In an embodiment, a plurality of transactions for accessing a database may be acquired. The database may be associated with a plurality of locks. The plurality of transactions may include a first transaction, a second transaction, and a third transaction. A logical serialization sequence for executing the transactions may be identified. The logical serialization sequence may indicate that (1) the first transaction is to be executed before the second transaction based on all locks that are required by the first transaction being available; (2) the second transaction is to be executed after the first transaction has completed execution based on the second transaction requiring a lock that is required by the first transaction; and (3) the third transaction is to be executed before or during execution of the first transaction based on all locks required by the third transaction being different than the locks required by the first transaction.

Abstract: The pressure sensitive adhesive is a copolymer of ethylene and propylene that has a maximum load between 6.4 N and 11.2 N in a lap joint shear strength test. The copolymer is prepared by mixing ethylene and propylene in the presence of a diimine nickel catalyst and polymethylaluminoxane (MAO) co-catalyst. The molar ratio of the ethylene to propylene feed is between 60:40 and 40:60. The polymerization is carried out at 30° C. and 1.3 bar. The polypropylene molar percentage in the resulting copolymer is between 42% and 88%, and the weight average molecular weight is between 24,917 and 33, 314 Da.

Abstract: A plunger type water pump mainly comprises a cavity body, a rotary main shaft and a plunger flow-distributing unit. The plunger flow-distributing unit comprises a flat valve assembly, a plunger-shoe assembly and a supporting valve assembly. The plunger-shoe assembly divides the cavity body into a high-pressure cavity and a low-pressure cavity independent of each other. The high-pressure cavity is in fluid communication with the flat valve assembly; and the low-pressure cavity is in fluid communication with the supporting valve assembly. The high-pressure water and the low-pressure water are independent of each other. This arrangement ensures a high volumetric efficiency of the water pump under ultra-high-pressure conditions and provides fluid support and lubrication for a friction coupling under high-speed heavy-load conditions to prolong the service life of the water pump.

Abstract: The present invention relates to a method for in vivo detection of a biofilm infection residing in a mammal, the method comprising (i) administering to the mammal a diagnostic-effective amount of a biofilm-specific probe, wherein the probe comprises a bio film-targeting moiety and a paramagnetic nanoparticle core; and (ii) imaging the mammal to detect the presence of the biofilm infection by observing the mammal using a magnetic resonance diagnostic technique after the biofilm-specific probe has been provided sufficient time to selectively bind to the bio film infection that may be present in the mammal. The invention also relates to methods of treatment of a bio film infection, and compositions and kits useful in the detection and/or treatment of bio film infections.

Abstract: The present invention discloses a channel estimation method for an orthogonal frequency-division multiplexing system with cyclic-delay diversity. The method makes pilots have the same amplitude and equally partitions the pilots into a number of pilot groups. In addition, the method equally spaces the pilots of each group in a frequency domain and determines the pilot locations and cyclic-delay coefficient of each pilot group in order to optimize the channel estimation of a receiver. The method can perform the channel estimation by using just one OFDM symbol.

Abstract: The gene responsible for encoding SERT has a functional polymorphism at the 5?-regulatory promoter region, which results in two forms, long (L) and short (S). The LL-genotype is hypothesized to play a key role in the early onset of alcohol use. The present invention discloses the differences in treatment and diagnosis based on the L or short genotypes as well as on a single nucleotide polymorphism of the SERT gene, the 3? UTR SNP rs 1042173. The present invention demonstrates the efficacy of using the drug ondansetron and similar drugs for treatment based on variations in the polymorphisms of the SERT gene as well as methods for diagnosing susceptibility to abuse of alcohol and other addiction-related diseases and disorders.

Abstract: The invention discloses an intermediate 1-methoxyl-2,6,10-trimethyl-1,3,5, 9-undec-tetraene, and a preparation method and uses thereof. In the synthesis method for the current lycopene intermediate 2-pos double bond C-14 aldehyde (2,6,10-trimethyl-2,5,9-undecatriene-1-aldehyde), expensive methyl iodide, polluting dimethyl sulphide and dangerous strong base are needed, so that the method is hardly applied to industrial production. The invention provides a new compound 1-methoxyl-2,6,10-trimethyl-1,3,5,9-undec-tetraene, and pure 2-pos double bond C-14 aldehyde can be prepared by hydrolyzing and refining the compound. The synthetic route is simplified and the great suitability for industrial production is achieved.
