Abstract: Anion exchange membrane and methods of making and using the same. In one embodiment, the anion exchange membrane may be made by a method that includes a two-step polymerization. In the first step, an ?-olefin monomer containing a pendant halide, such as 8-bromo-1-octene, may be polymerized by Ziegler-Natta polymerization to form a first polymer portion, the first polymer portion being a homopolymer. In the second step, the polymerization is charged with a non-functionalized ?-olefin monomer, such as ethylene, thereby forming a second polymer portion, the second polymer being a copolymer made up predominantly of the non-functionalized olefin monomer. If desired, a small amount of an ?-olefin monomer containing a crosslinking functionality may be included in the first and/or second steps. Following the two-step polymerization, the polymer is fabricated into a thin film. Thereafter, the thin film may be functionalized by replacing the pendant halides with pendant cations.

Abstract: To automate time series forecasting machine learning pipeline generation, a data allocation size of time series data may be determined based on one or more characteristics of a time series data set. The time series data may be allocated for use by candidate machine learning pipelines based on the data allocation size. Features for the time series data may be determined and cached by the candidate machine learning pipelines. Predictions of each of the candidate machine learning pipelines using at least the one or more features may be evaluated. A ranked list of machine learning pipelines may be automatically generated from the candidate machine learning pipelines for time series forecasting based upon evaluating predictions of each of the one or more candidate machine learning pipelines.

Abstract: The present invention relates to the technical field of photosensitizers, and particularly to a near-infrared nano-photosensitizer and a preparation method and use thereof. The near-infrared nano-photosensitizer in the present invention is modified by conjugation extension of the boron dipyrromethene core, achieving absorption and emission spectra close to the near-infrared region. A polyfluoroalkyl group and a polyethylene glycol group are introduced to the boron dipyrromethene structure to obtain an amphiphilic photosensitizer. By means of the strong fluorine-fluorine interaction between the polyfluoroalkyl group and the hydrophilic interaction of the polyethylene glycol group, a nano-photosensitive micelle with an ultra-low CMC value is ultimately constructed. Boron dipyrromethene is induced by fluorine-fluorine interaction to undergo J-aggregation, causing the maximum absorption peak to red-shift to the near-infrared region, beneficial to the deep phototherapy of tumors.
