Flat-top narrow bandpass filters based on cascaded resonant gratings
Narrow bandpass filters are useful in numerous practical applications including laser systems, imaging, telecommunications, and astronomy. Traditionally implemented with thin-film stacks, there exists alternate means incorporating photonic resonance effects. Accordingly, here we disclose a new approach to bandpass filters that engages the guided-mode resonance effect working in conjunction with a cavity-based Fabry-Pérot resonance to flatten and steepen the pass band. Both of these resonance mechanisms are native to simple resonant bandpass filters placed in a cascade. To support the disclosure, numerical examples provide quantitative spectral characteristics including pass-band shape and sideband levels. Thus, we compare the spectra of single-layer 1D- and 2D-patterned resonant gratings with a dual-grating cascade design incorporating mathematically identical gratings. Dual and triple cascade designs are measured against a classic multi-cavity thin-film filter with 151 layers. The disclosed examples show comparable and improved results achieved with these sparse structures while engaging principles absent in corresponding state-of-the-art technology. |

Chromatograph mass spectrometer
Sequential identification numbers are automatically provided and undisplayed, constant, unique numbers are assigned to each event registered in an analysis condition setting table 100. Since correspondence information between the identification numbers and the unique numbers changes due to the reassignment of identification numbers when an event is deleted from the table, event identification numbers for each compound are changed by referring to the correspondence information on a compound information table. As a result, it is possible to avoid the misalignment of event identification numbers between both tables. In addition, when an instruction is given to coordinate the time information or m/z information on both tables, the information on one table is reflected on the other table in accordance with the identification numbers. |

A filter made of a sponge material having air permeability and elasticity is interposed between an exhaust port of an exhaust gas sampling unit and a sampling port to thereby close a gap between the exhaust port and the sampling port.

The magnet's center aligns with the shaft's axis of rotation and the magnet's magnetic pole is oriented orthogonally to the shaft's axis of rotation. The motion sensor system produces an output signal representing an absolute rotational position of the magnet. The control system stores an expected rotational position of the motor and determines whether the motion sensor system's output signal matches the stored position. When the output signal does not match the stored position, the control system rotates the motor position where the output signal matches the stored position. |

Methods for predicting the survival time of patients with decompensated alcoholic cirrhosis
The present invention relates to methods for predicting the survival time of patients with decompensated alcoholic cirrhosis. In particular, the present invention relates to a method for predicting the survival time of a patient with decompensated alcoholic cirrhosis comprising i) determining the expression level of OAS2 or MX2 in a sample of peripheral blood mononuclear cells obtained from the patient, ii) comparing the level determined at step i) with a predetermined reference value and iii) and concluding that the patient will have a short survival time when the level determined at step i) is higher than its predetermined reference value or concluding that the patient will have a long survival time when the level determined at step i) is lower than the predetermined reference value. |

Method and system for microbiome-derived diagnostics and therapeutics for endocrine system conditions
A method for at least one of characterizing, diagnosing, and treating an endocrine system condition in at least a subject, the method comprising: receiving an aggregate set of biological samples from a population of subjects; generating at least one of a microbiome composition dataset and a microbiome functional diversity dataset for the population of subjects; generating a characterization of the endocrine system condition based upon features extracted from at least one of the microbiome composition dataset and the microbiome functional diversity dataset; based upon the characterization, generating a therapy model configured to correct the endocrine system condition; and at an output device associated with the subject, promoting a therapy to the subject based upon the characterization and the therapy model. |

Nano-sensors for nucleic acid detection and discrimination
Methods, systems, and nano-sensor devices are disclosed for detecting or discriminating nucleic acids with a single nucleotide resolution based on nucleic acid strand displacement. The detection can be made by time-lapse fluorescence measurements or by electro-based graphene FET, which can be combined with wireless communication to provide real-time transmission of the detected signals. |
