  2. SARS-CoV-2 Omicron variant - Wikipedia

    en.wikipedia.org/wiki/SARS-CoV-2_Omicron_variant

    BA.2.86 is notable for having more than thirty mutations on its spike protein relative to BA.2. [187] The subvariant , which was first detected in a sample from 24 July 2023, [ 188 ] is of concern due to it having made an evolutionary jump on par with the evolutionary jump that the original Omicron variant had made relative to Wuhan-Hu-1, the ...

  3. Multiple myeloma - Wikipedia

    en.wikipedia.org/wiki/Multiple_myeloma

    When one tumor is present, it is called a plasmacytoma; more than one is called multiple myeloma. [10] Multiple myeloma is diagnosed based on blood or urine tests finding abnormal antibody proteins (often using electrophoretic techniques revealing the presence of a monoclonal spike in the results, termed an m-spike), bone marrow biopsy finding ...

  4. Orders of magnitude (mass) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(mass)

    An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.

  5. Orders of magnitude (pressure) - Wikipedia

    Military submarine max. rated pressure (est.) of Seawolf-class nuclear submarine, at depth of 500 m [65] [66] 10-21 MPa 1,500–3,000 psi Chamber pressure of a high-powered (non-carbon dioxide) air gun 6.9–27 MPa 1,000–4,000 psi Water spray pressure used by pressure washers [67] 9.2 MPa 1,300 psi Atmosphere of Venus [68] 10 7 Pa

  6. Moment magnitude scale - Wikipedia

    en.wikipedia.org/wiki/Moment_magnitude_scale

    The moment magnitude scale (MMS; denoted explicitly with M or M w or Mwg, and generally implied with use of a single M for magnitude [1]) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. M w was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori.

  7. Mach number - Wikipedia

    en.wikipedia.org/wiki/Mach_number

    It is first determined whether M is indeed greater than 1.0 by calculating M from the subsonic equation. If M is greater than 1.0 at that point, then the value of M from the subsonic equation is used as the initial condition for fixed point iteration of the supersonic equation, which usually converges very rapidly. [8]

  8. SARS-CoV-2 Alpha variant - Wikipedia

    en.wikipedia.org/wiki/SARS-CoV-2_Alpha_variant

    The test matches RNA in three locations, and stopped working for the spike gene due to the HV 69–70 deletion—a deletion of the amino acids histidine and valine in positions 69 and 70, respectively [262] —in the spike protein of lineage B.1.1.7. This made preliminary identification easier because it could be better suspected which cases ...

  9. Chandrasekhar limit - Wikipedia

    en.wikipedia.org/wiki/Chandrasekhar_limit

    A strong indication of the reliability of Chandrasekhar's formula is that the absolute magnitudes of supernovae of Type Ia are all approximately the same; at maximum luminosity, M V is approximately −19.3, with a standard deviation of no more than 0.3. [46]: eq. (1) A 1-sigma interval therefore represents a factor of less than 2 in luminosity ...
