  2. Cancer slope factor - Wikipedia

    en.wikipedia.org/wiki/Cancer_slope_factor

    Cancer slope factors (CSF) are used to estimate the risk of cancer associated with exposure to a carcinogenic or potentially carcinogenic substance. A slope factor is an upper bound, approximating a 95% confidence limit , on the increased cancer risk from a lifetime exposure to an agent by ingestion or inhalation .

  3. Minimum mean square error - Wikipedia

    Standard method like Gauss elimination can be used to solve the matrix equation for .A more numerically stable method is provided by QR decomposition method. Since the matrix is a symmetric positive definite matrix, can be solved twice as fast with the Cholesky decomposition, while for large sparse systems conjugate gradient method is more effective.

    Increased Risk of Solid Cancer with Dose for A-bomb survivors, from BEIR report.Notably, this exposure pathway occurred from essentially a massive spike or pulse of radiation, a result of the brief instant that the bomb exploded, which while somewhat similar to the environment of a CT scan, is wholly unlike the low dose rate of living in a contaminated area such as Chernobyl, where the dose ...

    Estimated change in probability: Based on table above, a likelihood ratio of 2.0 corresponds to an approximately +15% increase in probability. Final (post-test) probability: Therefore, bulging flanks increases the probability of ascites from 40% to about 55% (i.e., 40% + 15% = 55%, which is within 2% of the exact probability of 57%).

    Mainly pancreatic cancer, but also colorectal cancer and other types of gastrointestinal cancer. [11] CA-125: Mainly ovarian cancer, [12] but may also be elevated in for example endometrial cancer, fallopian tube cancer, lung cancer, breast cancer and gastrointestinal cancer.

  7. Effective dose (radiation) - Wikipedia

    en.wikipedia.org/wiki/Effective_dose_(radiation)

    Effective dose is a dose quantity in the International Commission on Radiological Protection (ICRP) system of radiological protection. [1]It is the tissue-weighted sum of the equivalent doses in all specified tissues and organs of the human body and represents the stochastic health risk to the whole body, which is the probability of cancer induction and genetic effects, of low levels of ...

    At the recommended cut-off scores of 88 and 83, the ACE was reported to have good sensitivity and specificity for identifying different forms of dementia and other impairments of memory and judgement (0.93 and 0.71; 0.82 and 0.96, respectively). [5] The ACE also incorporated the MMSE, such that this score (out of 30) might also be generated. [2 ...

  9. MMSE - Wikipedia

    MMSE can refer to: Mini–mental state examination, a questionnaire to measure cognitive impairment; Minimum mean square error, an estimation method that minimizes the mean square error; Multimedia Messaging Service Environment, the servers in a mobile telephony network required for Multimedia Messaging Service messaging.
