Financial fragility and the structure of financial markets [PDF]
, 2018 This paper investigates the role of financial stucture on he financial fragility of the economy. It argues that while strucures is indipendent of the degree of what Misky calls financial fragility, it will have an impact on the rate of contagion by which financial fragility produces general economic instability.

Advanced Engineering Materials, EarlyView.Laboratory protocols for producing thin‐film pH electrodes for sterilized single‐use technologies have been successfully developed into a semiautomated workflow, with higher throughput and precision of membrane thickness. Accuracies are within 0.05 pH units versus ground truth, and uncertainty analysis reveals the largest sources of error to be derived
