Abstract: The present disclosure provides a polyzirconium coagulant obtained by performing a controllable hydrolytic polymerization reaction on a simple zirconium salt. The polyzirconium coagulant has a good coagulation performance when removing turbidity, organic matter, phosphate, and fluoride from water body. The coagulation effluent has a low concentration of residual metal and a mild change of pH. At the same dose, compared with a simple zirconium salt and polymerized zirconium chloride with a low polymerization degree, the polyzirconium coagulant prepared by the present disclosure has a wider workable pH and dose range. Besides, compared with other metal salt coagulants, the coagulant prepared by the present disclosure has a better decontamination performance. In addition, by using the polyzirconium coagulant prepared by the present disclosure, the floc has a large size and is rapid to settle. The residual zirconium concentration is low, and pollutant removal efficiency is high.

Abstract: A method of adjusting a neuromuscular-signal sensor is provided. The method includes monitoring, based on data from a wearable device that includes a neuromuscular-signal sensor, an impedance at the sensor that impacts the neuromuscular-signal sensor’s ability to sense neuromuscular signals. The neuromuscular-signal sensor is coupled to the wearable device such that it contacts a portion of a user’s skin. In response to detecting a change in the impedance at the neuromuscular-signal sensor that causes the impedance to be outside of a predefined range of impedance values, the method includes causing an adjustment to an operational characteristic (e.g., causing the neuromuscular-signal sensor to move or adjusting an electrical characteristic) associated with the neuromuscular-signal sensor such that the impedance at the neuromuscular-signal sensor is within the predefined range of impedance values after the adjustment to the operational characteristic.

Abstract: Apparatuses, systems, and methods for refresh modes. A memory may need to perform targeted refresh operations to refresh the ‘victim’ word lines which are near to frequently accessed ‘aggressor’ word lines. To refresh the victims at a high enough rate, it may be desirable to refresh multiple victims as part of the same refresh operation. However, certain word lines (e.g., word lines in a same section or adjacent sections of the memory) cannot be refreshed together. The memory may have a section comparator, which may check stored aggressor addresses and may provide a signal if there are not two stored addresses which can be refreshed together. Based, in part, on the signal, the memory may activate one of several different refresh modes, which may control the types of refresh operation performed responsive to a refresh signal.

Abstract: Bayesian recursive estimation is used to analyze performance parameters of a membrane separation system based on historical operational data of a membrane system. Bayesian estimation considers historical data over prior time intervals to predict future membrane separation performance to avoid unexpected downtime and unanticipated maintenance. A set of state variables used for modeling performance is used with a degradation model of to anticipate performance changes and maintenance based on measured properties of permeate, non-permeate, and feed flows.
