    摘要： Provided are products of manufacture and methods for the removal of gaseous methane and carbon dioxide, for example, for the removal of environmental or atmospheric or anthropogenically produced gaseous methane and carbon dioxide. Products of manufacture as provided herein comprise living emission abolish filters (LEAFs) for the removal of methane and carbon dioxide, where the “living” component of the “emission abolish filter”, or biofilter, comprises a methane-capturing bioagent, optionally comprising halophilic methanotroph bacterium. Products of manufacture as provided herein are manufactured as arrays, sheets, microfibers and/or microbeads comprising immobilized living, active methane-capturing bioagents, optionally comprising halophilic methanotroph bacterium. In alternative embodiments, the methane-capturing bioagents are enclosed or immobilized in or onto a crystal gel matrix or a nanoshell. Products of manufacture as provided herein can replace gas flares, flare stacks or a gas combustion devices, or are used with a methane scrubbing system.

    摘要： Systems and methods facilitating objective evaluations of subjects to facilitate detecting clinically relevant changes in balance are provided. The system includes a portable balance board with a sensor in each of four feet for detecting downward force. Each sensor is communicatively coupled to a circuit board with a wired or wireless communication capability. A subject stands on the balance board and each sensor sends a signal to the circuit board, which communicates the four signals to a companion device that uses the signals to calculate the center of pressure (“COP”) of the subject over time. The subject can perform the BESS test and the resulting COP data is used to calculate a field path length for the subject. The field path length is compared to a previously determined baseline path length for the subject to detect any clinically relevant change in balance of the subject.

    摘要： In this application, a set of orthogonal functions is introduced whose power spectral densities are all rectangular shape. To find the orthogonal function set, it was considered that their spectrums (Fourier transforms of the functions) are either real-valued or imaginary-valued, which are corresponding to even and odd real-valued time domain signals, respectively. The time domain functions are all considered real-valued because they are actually physical signals. The shape of the power spectral densities of the signals are rectangular thus, the Haar orthogonal function set can be employed in the frequency domain to decompose them to several orthogonal functions. Based on the inverse Fourier transform of the Haar orthogonal functions, the time domain functions with rectangular power spectral densities can be determined. This is equivalent to finding the time-domain functions by taking the inverse Fourier transform of the frequency domain Walsh functions. The obtained functions are sampled and truncated to generate finite-length discrete signals. Truncation destroys the orthogonality of the signals. The Singular Value Decomposition method is used to restore the orthogonality of the truncated discrete signals.

    摘要翻译： 在此应用中，引入了一组正交函数，其功率谱密度均为矩形。 为了找到正交函数集，认为它们的频谱（函数的傅立叶变换）分别是实值或虚值，它们分别对应于偶数和奇数实数时域信号。 时域功能都被认为是真实的，因为它们实际上是物理信号。 信号的功率谱密度的形状是矩形的，因此可以在频域中采用哈尔正交函数集，将其分解成若干正交函数。 基于Haar正交函数的傅立叶逆变换，可以确定具有矩形功率谱密度的时域函数。 这相当于通过采用频域沃尔什函数的逆傅立叶变换来找到时域函数。 获得的函数被采样和截断以产生有限长度的离散信号。 截断会破坏信号的正交性。 奇异值分解法用于恢复截断离散信号的正交性。
