The strategy of flow channel with wrinkles and calcium sites for single-step CH purification from C2 gases and methanol-to-olefins (MTO) products separation was realized in . The adsorption amounts showed a total reversal order of CH > CH > CH > CH at 298 K. Modeling indicated that the wrinkles and Ca facilitated the full contact of CH and CH. Breakthrough experiments illustrated that could yield pure CH in a single step with a productivity of 0.78 mmol g. In a lone adsorption/desorption cycle for MTO product separation, the productivities of CH and CH were 1.96 and 1.29 mol g, standing as the highest recorded values.

Protocol for extracting flow hydrograph shape metrics for use in time-series flood hydrology analysis.

The shape characteristics of flow hydrographs hold essential information for understanding, monitoring and assessing changes in flow and flood hydrology at reach and catchment scales. However, the analysis of individual hydrographs is time consuming, making the analysis of hundreds or thousands of them unachievable. A method or protocol is needed to ensure that the datasets being generated, and the metrics produced, have been consistently derived and validated.

Diffraction imaging of cells allows rapid phenotyping by the response of intracellular molecules to coherent illumination. However, its ability to distinguish numerous types of human leukocytes remains to be investigated. Here, we show that accurate classification of three lymphocyte subtypes can be achieved with features extracted from cross-polarized diffraction image (p-DI) pairs.

Cell-laden, scaffold-based tissue engineering methods have been successfully utilized for the treatment of bone fractures. In such methods, the rate of scaffold biodegradation, transport of nutrients, and removal of cell metabolic wastes are critical fluid-dynamics factors, affecting tissue regeneration. Therefore, there is a critical need to identify the underlying material transport mechanisms associated with stem cell-driven, scaffold-based bone tissue regeneration.

Complex tissue flows in epithelia are driven by intra- and inter-cellular processes that generate, maintain, and coordinate mechanical forces. There has been growing evidence that cell shape anisotropy, manifested as nematic order, plays an important role in this process. Here we extend an active nematic vertex model by replacing substrate friction with internal viscous dissipation, dominant in epithelia not supported by a substrate or the extracellular matrix, which are found in many early-stage embryos.

Background: Existing work suggested that AD pathology can affect the direction and intensity of information signaling in functional brain regions. The present study evaluates the time‐delayed effective connectivity of normal controls (NC) and patients with mild cognitive impairment (MCI) under motion‐detection tasks and explores identification of possible anomalies and deviated patterns in effective connectivity associated with AD pathology.
Method: Our research focuses on task‐based EEG (64‐channel), where participants were asked to perform a motion direction discrimination task.
