Abstract

A system for mixing first and second solutions is provided. The system comprises: i) a syringe proportioner comprising a base adapted to receive first and second input syringes, and a gear assembly to drive a plunger of each of the input syringes to empty solution from each of the input syringes at a predetermined flow rate; ii) a channel comprising first and second inlets and a single outlet, the first and second inlets being adapted to fluidly couple respectively with first and second fluid expelling ends of each of the first and second input syringes, to receive solution from the first and second syringes; and iii) a static mixer comprising a fluid receiving end and a fluid discharging end, wherein the fluid receiving end is adapted to fluidly couple with the outlet of the channel and receive solution therefrom and the fluid discharging end is adapted to discharge fluid, said mixer comprising an internal geometry which provides mixing of a first and second solutions. The system is particularly useful for mixing solutions of different viscosities, for example, a cell suspension with a biomaterial solution to achieve effective mixing while minimizing sheer stress to retain cell viability.

Abstract

Various embodiments are described herein for a system and method for condition monitoring and detecting and diagnosing faults in electromechanical or electrochemical systems and batteries using a frequency-domain statistical analysis framework. The method comprises receiving raw time-domain signals from one or more sensors monitoring the electromechanical or electrochemical system, applying a Short-Time Fourier Transform to convert the time-domain signals into a spectrogram, and segmenting the spectrogram into a plurality of frequency band segments. Each segment is independently analyzed using Principal Component Analysis based Multivariate Statistical Process Control, followed by statistical smoothing of the MSPC outputs. Fault conditions can be classified based on the smoothed statistical indicators, enabling accurate identification of deviations from baseline behavior.

Abstract

Example methods, compositions and structures are presented whereby sub-10-nm-thick strain-relieving Si1-xGex layers can be realized by Ge ion implantation, into, and selective oxidation of, Si(111) wafers. The resulting Ge-rich layers are fully strain relaxed via a network of misfit dislocations at the Si/Si1-xGe, interface, which do not propagate through the Si1-xGex film. The dislocation network has been found to coincide with a periodic variation in the composition at the Si/Si1-xGex interface and is believed to result from the defect-medicated diffusion of Si atoms from the Si substrate through the Si1-xGex layer to the above SiO2 layer. The epitaxial growth of GaAs on such ultra-thin substrates is demonstrated, presenting a promising approach for solving the long-standing challenge of local, monolithic integration of III-V optoelectronics on the Si platform.

Abstract

Systems and methods are disclosed for determining the spatial distributions of radionuclides in tissue samples via mass spectrometry imaging. After administration of a radiopharmaceutical that contains a radionuclide, a mass spectrometry imaging system, such as an imaging mass cytometer or a multiplexed ion beam imaging system, is employed to interrogate a tissue sample to obtain a dataset. The radiopharmaceutical includes, or generates via radioactive decay of the radionuclide, a metal isotope detectable by the mass spectrometry imaging system. The dataset is processed to determine a spatial distribution of the metal isotope within the tissue sample, thereby characterizing the spatial distribution of the radionuclide delivered within the tissue sample. The tissue sample may be stained with a biomarker reagent that includes an additional metal isotope attached to a biomarker ligand, enabling the spatially multiplexed and co-registered analysis. The present methods can be adapted to infer and assess localization of non-radioactive pharmaceuticals.

Abstract

The present disclosure relates to solid-state sensors that exploit a unique sensing mechanism which amplifies the response of ion-selective membranes (ISM) several fold. In the presence of the analyte, such as lead, the binding sites within the membrane bind with the analyte modulating the interactions between the binding sites and the chemiresi stive film. This competitive binding provides a higher sensitivity when compared with conventional ion-selective electrode configurations. It also differs from a simple chemiresistor covered with an ISM because the reference electrode can be eliminated. The impact of these interactions on the conductivity of the film can also be maximized by its surface treatment, ultimately achieving a lower level of detection than possible with potentiometric methods. Sensors developed using this design may be employed as aqueous continuous in situ ion sensors to detect harmful levels of analytes in surface, drinking, or wastewater.

Abstract

Described is a method for assessing aortic valve calcification using contrast-enhanced CT. The method comprises: receiving CT images of the aortic valve; pre-processing received images to have a field of view focused on an aortic root corresponding to the aortic valve; implementing a fast-marching method for the pre-processed images to segment the aortic valve from surrounding tissue to generate an aortic root model; determining multiple principal axes and multiple landmark points based on the pre-processed images and the aortic root model to define a local coordinate system relative to leaflets of the aortic valve; generating a calcification model based on the pre-processed images and aortic root model by iteratively changing an initial estimate of calcific HU threshold until a minimum false positive rate FPR criterion is reached; and generating an indicator quantifying calcification of the aortic valve based on the calcification model, the principal axes and the landmark points.

Abstract

Described is a Doppler-based non-invasive computational diagnostic method for personalized cardiology of subjects (e.g., patients with valvular diseases in both pre and post intervention status). The method may be performed for determining dynamic behavior of an aortic valve of the subject, the aortic valve having multiple asymmetric valve leaflets. The method includes receiving Doppler echocardiography images of the subject; processing the received images to reconstruct a 3D geometry of the valve leaflets; determining transient pressure boundary conditions for the valve leaflets using a lumped parameter model specific to the subject; performing a first finite element simulation to determine one or more geometrical parameters for the valve leaflets; iteratively calibrating initial value of one or more material parameters for the subject; and performing a second finite element simulation, based on the calibrated one or more material parameters, to determine an indicator of the dynamic behavior of the aortic valve.

Abstract

An optical grating comprising a refractive index with a periodic pattern that includes a base period Λ0; a periodic sampling of the base period, with a first period Λ1 and a first duty cycle p1, thereby defining a single-sampled grating (SSG); and a periodic sampling of the SSG, with a second period Λ2 and a second duty cycle p2. The resulting dual-sampled grating (DSG) can have a reflection spectrum containing reflection peaks. If two DSGs having different reflection spectra share a common interface, a tunable optical filter can be produced, where electrical or heating means can cause a reflection peak of one spectrum to be shifted to coincide with a reflection peak of the other spectrum, thereby filtering the corresponding wavelength. By inserting between the two DSGs a gain medium and a phase-tuning medium, a laser source structure is realized. Either device can be produced by etching or stacking methods.
