Hypothesis: systemic low-grade tissue hypoxia as contributing causative mechanism for Long COVID

Silent hypoxia is one of the key clinical features of COVID-19 infection. Some of the hypothesized underlying causes of silent hypoxia, such as endothelial and micro-vascular dysfunction, and micro-clots inhibiting perfusion, would exert a... continue reading

Calculation of multi-dimensional information acquisition in space potential disintegration target

Some space debris belongs to the upper stage of the rocket, and propellant remains inside the debris, which may explode and generate more space debris. In order to identify potential disintegration targets in space, understand the remaining amount... continue reading

Spacecraft cluster cloud high-frequency optimization computing theory

The satellite-ground collaborative computing requires information transmission between the satellite and the ground, which will cause significant delay, resulting in a time from calculation to execution of more than milliseconds. In the best case,... continue reading

Develop a uniform tool to assess sanitation in urban slums

The quality of sanitation is poor in urban slums across the globe. Sanitation deprivations are greater in urban slums in developing countries, which continually experience unmanageable influxes of slum dwellers.

Governments have limited... continue reading

Utility of kidney dialysis for recovery following marathons or ultra-marathons

Recent observations indicate the presence of Acute Kidney Injury and impaired renal function in a majority of participants in marathons of a standard distance of 42.2km (26.2mi). This impairment, and the resulting electrolyte imbalances, may delay... continue reading

Possible role of ozone depletion in insect depopulation

Insect populations have been found to be precipitately decreasing, with some studies indicating a decline in flying insect biomass of as much as 80% since the 1980s, in some areas. A number of possible causes for this phenomenon have been... continue reading

Pragmatic Autoethnography: Thoughts on why it may be needed

Autoethnography is a reflexive subjective narrative qualitative research method, both a product and a process, whereby the researcher (‘auto’) depicts (‘graphy’) their understanding of their lived experience within an ethnographic (‘ethno’) or... continue reading

Space Debris Fingerprint Definition and Identification

The amount of space debris is increasing, and the threat to normal human space activities is also increasing. The concept of fingerprints of space debris is proposed here. It is necessary to define the fingerprints of space debris, and identify... continue reading

Testing the role of radicals in sleep deprivation`s antidepressant effect.

Recent research on sleep deprivation(SD) has demonstrated in the mouse large free radical increases after two days SD, selectively in the small intestine (and large).1. This timescale closely parallels that of the quick, hard to sustain, human... continue reading

Manual therapy's marginal utility

Manual therapy's treatment techniques integrated a multitude of physical therapy modalities to address functional issues. In clinical settings, the majority of the treatment duration is a set time or with the ending time based on the experiences... continue reading
