Resilient Quantum Electron Microscopy
Shot-noise currently limits the resolution of electron cryomicroscopy of
beam-sensitive biological specimens. Quantum metrology, despite the potential
to surpass this limit, is notoriously sensitive to decoherence. We show that it
is possible to significantly neutralize the adverse effect of inelastic
electron scattering. This could allow us to study thick specimens of real
biological interest.Comment: 21 pages, 7 figures, 2 tables; main conclusions unchange
Universal Quantum Electron Microscopy: A Small-Scale Quantum Computing Application with Provable Advantage
We propose a simple design of a quantum electron microscope that ``queries''
a beam-sensitive phase object, such as a biological specimen, as part of
quantum computation. Lower quantum query complexity, not the time complexity,
of a quantum algorithm means less specimen damage, which translates to more
data extracted from the specimen. Hence small-scale quantum computing offers
provable quantum advantage in this context. A possible application of the
proposed microscope is the Grover search for a true structure, out of a set of
candidate structures.Comment: 11 pages, 3 figure
Industrial Networks between China and the Countries of the Asia-Pacific Region
This paper investigates the changes in the structures of industrial networks that have occurred in the Asia-Pacific region in line with the rapid growth of the Chinese economy. Analyses using international input-output tables revealed that during the 1990s, there was a significant increase in the dependence of Asian countries’ manufacturing industries, such as textiles and electronics, on China’s industries, though industries in Japan and the United States remain important as the main suppliers of industries in Asian countries
Regulation of bone by the adaptive immune system in arthritis
Studies on the immune regulation of osteoclasts in rheumatoid arthritis have promoted the new research field of 'osteoimmunology', which investigates the interplay between the skeletal and immune systems at the molecular level. Accumulating evidence lends support to the theory that bone destruction associated with rheumatoid arthritis is caused by the enhanced activity of osteoclasts, resulting from the activation of a unique helper T cell subset, 'Th17 cells'. Understanding the interaction between osteoclasts and the adaptive immune system in rheumatoid arthritis and the molecular mechanisms of Th17 development will lead to the development of potentially effective therapeutic strategies
