摘要： A universal terminator includes a heterocycle other than naturally occuring DNA heterocycles such as adenine, cytosine, guanine and thymine. In terminating strand synthesis, the hybridized primer-template is split into four aliquots. In the "A" vial is added DNA polymerase and normal amounts of "C", "G", and "T" deoxynucleotides, along with a reduced amount of "A" deoxynucleotide and an amount of the universal terminator such that statistically the universal terminator has less than a one percent chance of being incorporated at sites where a "C", "G", or "T" deoxynucleotide should be incorporated and about a one percent chance of being incorporated at sites where an "A" deoxynucleotide should be incorporated. Similar strategies are followed for the "C", "G", and "T" vials, except that the amount of "C", "G" and "T" deoxynucleotides are reduced for their respective vial.

摘要： In one preferred embodiment, a gas analyzer is presented that focuses light beams through gas cells without reflecting the light beams off the walls of the cells. By eliminating wall reflections, dirt or debris on the walls of the cells will not result in inaccurate gas concentration measurements. In another preferred embodiment, a gas analyzer is disclosed having removable gas cells, which allows a user to easily clean the cells instead of returning a contaminated gas analyzer to service personnel for cleaning. In yet another preferred embodiment, a gas analyzer has a purged gas flow channel between source and detector sections of the analyzer to remove contaminants that can result in inaccurate gas concentration measurements. In an additional preferred embodiment, a gas analyzer is disclosed which has a heat exchanger to equilibrate the temperature of incoming air to the temperature of the analyzer's gas cells, thereby avoiding temperature-based errors in gas concentration measurements.
摘要翻译：在一个优选实施例中，提出了一种气体分析器，其将光束聚焦通过气室而不将光束反射离开池的壁。通过消除壁面反射，电池壁上的污垢或碎屑不会导致不准确的气体浓度测量。在另一个优选实施例中，公开了一种气体分析器，其具有可拆卸的气体电池，这允许用户容易地清洁电池，而不是将污染的气体分析仪返回给维修人员进行清洁。在又一个优选实施例中，气体分析器在分析器的源和检测器部分之间具有净化的气体流动通道，以去除可能导致不准确的气体浓度测量的污染物。在另一优选实施例中，公开了一种气体分析器，其具有热交换器以使进入空气的温度平衡到分析器的气体单元的温度，由此避免了气体浓度测量中的基于温度的误差。

摘要： Laser-based spectroscopy systems and methods including a laser source that emits a beam of radiation, an optical resonant cavity having at least two cavity mirrors, and at least one beam filtering element positioned along a path of the beam external to the cavity and having a front surface, wherein the front surface is oriented such that an intersection of the beam and the surface is at an angle, such as the Brewster's angle or a pseudo-Brewster's, that reduces or eliminates reflection of a predominant polarization component of the beam by the filtering element.

摘要： A system and method to obtain correct gas density and flux measurements using (i) gas analyzer (open-path, or closed-path gas analyzers with short intake tube, or any combination of the two); (ii) fast temperature or sensible heat flux measurement device (such as, fine-wire thermocouple, sonic anemometer, or any other device providing fast accurate gas temperature measurements); (iii) fast air water content or latent heat flux measurement device (such as, hygrometer, NDIR analyzer, any other device providing fast accurate gas water content measurements); (iv) vertical wind or sampling device (such as sonic anemometer, scintillometer, or fast solenoid valve, etc.) and (v) algorithms in accordance with the present invention to compute the corrected gas flux, compensated for T-P effects. In case when water factor in T-P effects is negligible, the fast air water content or latent heat flux measurement device (item iii in last paragraph) can be excluded.

摘要： Multi-functional piezo-actuated flow control systems and methods for use in gas exchange analysis systems such as photosynthesis measurement systems. A fluid valve assembly module includes a housing structure including a plurality of ports and a plurality of fluid passageways interconnecting the ports, and a plurality of piezo-actuated valves in fluid communication with the fluid passageways, each valve including a piezo element that controls flow along a passageway, wherein the passageways and valves are arranged within the housing structure so as to define a fluid control module, which includes a flow swapping component, a flow splitting component and a flow pressurization component. The flow swapping component has first and second inlets and first and second output ports and is configured to receive a first fluid flow at the first inlet and a second fluid flow at the second inlet and in a first operational mode to direct the first fluid flow to the first output port and the second fluid flow to the second output port, and in a second operational mode to direct the first fluid flow to the second output port and the second fluid flow to the first output port. The flow splitting component has an input port, a third output port and a first outlet and is configured to receive an input fluid flow at the input port and to control an amount of the input fluid flow provided to the third output port and to the first outlet in a continuously adjustable manner, wherein the first outlet is fluidly connected to the first inlet of the flow swapping component and the third output port is adapted to be fluidly coupled with an external reservoir. The flow pressurization component has an entry port in fluid communication with a second outlet and is configured to receive a third fluid flow at the entry port and to control the pressure of the third fluid flow at the second outlet, wherein the second outlet is fluidly connected to the second inlet of the flow swapping component and the entry port is adapted to be fluidly coupled with the external reservoir.
