Abstract: Provided for herein is a method of cell transplantation using an injection attachment having a hub containing a plurality of cells and a cannula extending from a distal end of the hub. The method includes orienting the injection attachment such that the cannula points downwardly until the plurality of cells settle together proximate the distal end, inserting the cannula into a tissue of a subject, and injecting the volume of cells into the tissue of the subject using the injection attachment.

Abstract: A mechanism for adaptively performing in-band network telemetry (INT) by a network controller is disclosed. The mechanism includes receiving one or more congestion indicators from a collector. An adjusted sampling rate is generated. The adjusted sampling rate is a specified rate of insertion of instruction headers for INT and is generated based on the congestion indicators. The adjusted sampling rate is transmitted to a head node, which is configured to perform INT via instruction header insertion into user packets.

Abstract: Transparent UV-absorbing solar cells are promising for the applications of powering electrochromic windows that regulate the transmission of visible and near-infrared photons for natural lighting and heating purposes, respectively. Current technologies focus on using organic solar cells for the application due to their narrow excitonic absorption and tunable bandgaps. However, transparent organic solar cells have drawbacks including the stability issue and thickness-induced problems, such as low yield rate and limited power conversion efficiency. Disclosed herein is the co-deposition of two or more materials by thermal evaporation to make visibly transparent inorganic perovskite films. By tuning the halide compositions, the inorganic perovskite films show absorption range in UV and near-UV region, which is well-suited to the application. Its high conductivity and absorbance enable it to be around 400 nm thick for devices, which is critical to improve the yield rate and efficiency.

Abstract: A multi-pixel spectroscopy sensor for spectral analysis of a sample under test including an array of pixel elements generating a dataset including a plurality of data values corresponding to the pixel elements upon illumination of the sample by a light source. Each of the pixel elements including a stack of layers including first and second reflective structures, a phase tuning element, a detector element, and contact elements. The sensor further includes a read-out circuit connected to each of the contact elements for simultaneous read-out of a plurality of photocurrents for generating and outputting the dataset for the spectral analysis of the sample under test. The phase tuning element of each of the pixel elements is configured for a different wavelength response of the light and each photodetector of the pixel elements is comprised of a semiconductor material.

Abstract: The present invention relates to a slanting-bed feed processing machine tool of a large propeller. The machine tool comprises a slanting column feed bed, a machine tool spindle, a workpiece rotary worktable, a large propeller and a bed feed mechanism. The present invention coordinates the geometrical relationship between the machine tool and the large propeller to ensure that the slanting column feed bed moves between two blades, thereby reducing the overhang length of the spindle. Different forms of workpiece rotary worktables and bed feed mechanisms are selected according to different slanting column feed beds. Four types of slanting column feed beds are designed, which can be selected, optimized and applied for different processing objects. The present invention enhances the processing stiffness of the spindle and solves the problem of poor processing quality of the large propeller caused by machine tool vibration.
