A substantial number of economists at various universities were work­ ing then on different ways of choosing between techniques of production. Some were particularly focused on maximising the total value of the output produced, whereas others wanted to maximise the surplus that was generated, and there were also some profit maximisers.

New Fiber-Optic Imaging Probe for More Effective Diagnoses of Various Diseases

New Fiber-Optic Imaging Probe for More Effective Diagnoses of Various Diseases Written by AZoOpticsMay 3 2021 Researchers from the University of Nottingham have designed a new ultrasonic imaging system that can be installed on the tip of a hair-thin optical fiber. The system can even be inserted into the human body to observe cell anomalies in 3D. Conventional microscope pictures of model biological cells (top). The phonon probe reproduces 3D images of the objects (color is height). Simultaneously, the probe detected stiffness-related measurements which are mapped in green on the top left image (bottom). The white scale bars are 10 micrometers long. Image Credit: University of Nottingham.
