An End of the COVID-19 Pandemic in Sight?

Authors: Edward J Steele, Reginald M Gorczynski, Robert A Lindley, Gensuke Tokoro, Daryl H. Wallis, Robert Temple, N. Chandra Wickramasinghe
Comments: 6 Pages.

We have set out to assess the data on the intensity of the COVID-19 pandemic with a view to making plausible predictions of its decline. A plot of “ % COVID-19 Associated Death per Day” versus the timing and extent of the roll out of national vaccination campaigns in Sweden, Denmark, Netherlands, United Kingdom, France, Germany, Italy and USA shows that the decline in the severity of the COVID-19 pandemic was well advanced noticeably before vaccinations began or could have become a significant contributory factor. Israel is an outlier in its manifest decline pattern, yet the data also demonstrate that vaccination has had no discernible impact at all on % Deaths per Day in Israel.

The Relevance of the Significant Reduction of X-ray Dose while Increasing the Resolution of Diagnostic Radiology

Authors: Avsharov Evgeny Mikhailovich
Comments: 9 Pages. In Russian

Currently existing approaches to the construction of x-ray diagnostic systems do not allow to combine in one product characteristics such as: - reduce x-ray dose by an order of magnitude, - reduction f the focal spot x-ray tube to a value of 0.1*0.1 mm and less in the millisecond time shooting the x-ray image; - decrease integral radiation power of the image frame coinciding with the period of radiation without increasing the instantaneous power of x-ray tube; - increasing resolution, dynamic x-ray detectors with a simultaneous increase in the speed of frames per second; - reducing the value of the ratio signal/noise and to increase the resolution of diagnostic images through mathematical processing of images. The output from the system of constraints is only possible through the creation of a new class of x-ray diagnostic systems, built on technology “Microsecond Radiology”, which incorporates the best of all three rentgenologii – Standard, Microfocus and Nanosecond rentgenology.

Curbing the Spread of Covid-19

Authors: Bertrand Wong
Comments: 6 Pages.

Covid-19 has made its unexpected entrance into the world some time in late 2019 causing much fear, economic disasters, suffering and fatalities throughout the world. This paper suggests a more aggressive intervention and strategy, for humanity should not let themselves be sitting ducks waiting for the virus to attack, and some possible methods for stopping Covid-19 in its path. (A useful summary is included just below.)
