摘要： A testing apparatus for dynamic characterization of a sample of a material under test. A terahertz (THz) time-domain spectroscopy system is configured and arranged to generate and detect terahertz waves to interrogate the sample. A shock wave loading system is configured and arranged to produce a shock wave in the sample concurrently with said THz spectroscopy device interrogating the sample. The sample undergoes changes in an index of refraction in response to the produced ultrafast shock wave in the sample that are detected by the terahertz spectroscopy system.

摘要： The present invention is directed to a system and method for photoeradication of microorganisms from a target. The method includes the step of obtaining test data for a plurality of experiments each of which comprises irradiating test microorganisms with a plurality of light pulses having a wavelength that ranges from 380 nm to 500 nm. The light pulses have a plurality of pulse parameters (peak irradiance, pulse duration, and off time between adjacent light pulses) and are provided at a radiant exposure that ranges from 0.5 J/cm2 to 60 J/cm2 during each of a plurality of irradiation sessions. The test data comprises a survival rate for the test microorganisms after irradiation with the light pulses. The method also includes the step of analyzing the test data to identify the pulse parameters for the light pulses and the radiant exposure for each of the irradiation sessions that result in a desired survival rate for the test microorganisms. The method further includes the step of irradiating the microorganisms of the target with light pulses having the identified pulse parameters at the identified radiant exposure for each of the irradiation sessions so as to photoeradicate all or a portion of the microorganisms.

摘要： Herein reported are new tricyclic cytidine compounds, such as 8-diethylamino-tC (8-DEA-tC), that respond to DNA and/or RNA duplex formation with up to a 20-fold increase in fluorescent quantum yield as compared with the free nucleoside, depending on neighboring bases. This turn-on response to duplex formation is by far the greatest of any reported nucleoside analogue that can participate in Watson-Crick base pairing. Measurements of the quantum yield of 8-DEA-tC mispaired with adenosine and, separately, opposite an abasic site show that there is almost no fluorescence increase without the formation of correct Watson-Crick hydrogen bonds. Kinetic isotope effects from the use of deuterated buffer show that the duplex protects 8-DEA-tC against quenching by excited state proton transfer. DFT calculations provide a rationale for the observed photophysical properties that is dependent on duplex integrity and the electronic structure of the analogue.

摘要： This application relates to techniques for obtaining wide area intermittent video (WAIV). Some embodiments disclosed herein include a method of obtaining WAIV. The method can include, for example, capturing images at a series of sensor stations having pre-determined locations along a flightline. The flightline can be repeated one or more times, where images are captured at the same sensor stations with each pass of the flightline. The captured images from the same sensor station may have replicated view geometry and may be co-registered and precisely aligned with pixel-level precision. The captured images from multiple sensor stations through time may also be displayed together based upon absolute or relative sensor station locations to create a temporal sequence of wide area intermittent video. The approach provides efficient methods for creating wide area video with reduced temporal imaging frame rates. Systems and devices for forming wide area intermittent video are also disclosed.

摘要： A device and method is described for electronic human prosthetics, and specifically a skull- and/or spine implantable bi-directional neural-communication/brain-machine interface (BBMI) device where the input, output and on-board computing are combined into a single unit to form a compact neuro-prosthetics device. This invention is also directed to a fully implantable wireless spinal electronic recording and stimulation system using the BBMI in a human. The bi-directional devices (BBMIs) communicate with other bi-directional brain-machine interface devices (BBMI) and/or with external controllers wirelessly. The compact implantable stimulator has ultrasonic secondary battery charging system. One or more BBMI can be wirelessly connected so that a closed loop of BBMIs, or a BBMI and an external controller, can wirelessly send trigger pulses to this fully implanted stimulator over the spinal cord.

摘要： The invention provides novel catalysts and methods of using catalysts for controlling the position of a double bond and cis/trans-selectivity in isomerization of terminal alkenes to their 2-isomers. Catalysts such as (pentamethylcyclopentadienyl)Ru formulas 1 and 3 having a bifunctional phosphine can be used in the methods. A catalyst loading of 1 mol % of formulas 1+3 can be employed for the production of (E)-2-alkenes at 40-70° C.; lower temperatures can be used with higher catalyst loading. Acetonitrile-free catalysts can be used at lower loadings, room temperature, and in less than a day to accomplish the same results as catalysts 1+3. The novel catalyst systems minimize thermodynamic equilibration of alkene isomers, so that the trans-2-alkenes of both non-functionalized and functionalized alkenes can be generated.
