    摘要: A system and method is provided that utilizes deep learning, including convolutional neural networks, to identify subject objects in unconstrained user images such as unknown pills. An image of, e.g., a pill, may be captured and subsequently processed using deep learning models to identify the pill. The deep learning models may be optimized to have a small footprint (in terms of computational and memory resources) suitable for a resource-limited device such as a smartphone while retaining a high object recognition accuracy. Each such model may also be run on modified versions of the unconstrained image, for example on color, greyscale, and gradient images, to focus the models on different distinguishing features of the object.

    摘要: The disclosure relates to a method for pretreating a sample for metals determination. The method includes: providing an aqueous sample mixture comprising a sample containing or suspected of containing one or more metals for detection; contacting the aqueous sample mixture with a first electrode (anode) comprising electrically conducting boron-doped diamond (BDD); electrically contacting the aqueous sample mixture with a second electrode (cathode); applying an electrical potential between the first electrode and the second electrode (i) to provide an electrical current therebetween and through the aqueous sample mixture, (ii) to generate hydroxyl ion (OH−) species at the first electrode, (iii) to oxidize and free the one or more metals for detection in the sample, thereby forming a pretreated aqueous sample comprising free metal ions in aqueous solution and corresponding to the one or more metals in the original sample; and withdrawing the pretreated aqueous sample comprising the free metal ions in aqueous solution. The pretreated aqueous sample can be analyzed for metal content using any desired conventional analysis technique.

    摘要: A multiband sensing system includes an active multiband sensing unit configured to transmit a radio frequency (RF) signal in multiple bands and communicate with a network. The active multiband sensing unit includes at least one transmitting antenna configured to transmit the RF signal. The multiband sensing system includes a passive multiband sensing unit including at least one receiving antenna configured to receive the RF signal, an acoustic actuator powered by the received RF signal including an actuating sensor element configured to actuate in response to receiving extracted modulated information of the RF signal, and an acoustic detector. The acoustic detector includes a detector transmitting antenna configured to backscatter a new frequency band signal to the active multiband sensing unit and a detector sensor element configured to sense data. The sensed data is modulated over the received RF signal to produce the new frequency band signal.

    摘要: The disclosure relates to a plant growth apparatus and related system to grow and maintain plants under controlled biotic conditions, for example to grow axenic (microbe-free) plants, gnotobiotic (defined microbiota) plants, and holoxenic (complex, or undefined microbiota) plants. This system allows aseptic bottom irrigation with water, soluble nutrients, chemicals, and/or microbiota. Plants can be inverted for dipping and/or vacuum infiltration. The system also allows for passive (gravity) drainage, thereby allowing for gas exchange and preventing root anoxia. A variety of plant growth substrates can be used within the plant growth apparatus as a plant growth medium. The plant growth apparatus, containing the growth substrate medium, can be completely flushed via the drainage port to remove potential toxic byproducts of the sterilization processes. The entire system is suitably constructed using autoclavable material.

    摘要: An electron spectroscopy system and method are disclosed. In another aspect, an ultrabright and ultrafast angle-resolved electron spectroscopy system is provided. A further aspect of the present system employs an electron gun, a radio frequency cavity and multiple spectrometers. Yet another aspect uses spectrometers in an aligned manner to deflect and focus electrons emitted by the electron gun. Moreover, an ultrafast laser is coupled to an electron spectroscopy system. A bunch of monochromatic electrons have their energy compressed and reoriented in an additional aspect of the present system. A further aspect of the present electron spectroscopy system employs adaptive and/or adjustable optics to optimize both time and energy compression. Another aspect provides at least two RF lenses or cavities, one before a specimen and one after the specimen.
