What's the difference between epocha and epochal?

Epocha


Definition:

  • (n.) See Epoch.

Example Sentences:

Epochal


Definition:

  • (a.) Belonging to an epoch; of the nature of an epoch.

Example Sentences:

  • (1) The adaptive filter processor was tested for retrospective identification of artifacts in 20 male volunteers who performed the following specific movements between epochs of quiet, supine breathing: raising arms and legs (slowly, quickly, once, and several times), sitting up, breathing deeply and rapidly, and rolling from a supine to a lateral decubitus position.
  • (2) The results indicate that the different EEG frequency bands during a given EEG epoch are generated by neural populations in different brain locations.
  • (3) The majority of classes have over 200 discrete epochs.
  • (4) By means of the adaptive estimation of the variance of respiratory movements, an amplitude-time window is calculated to choose between epochs with breaths and apnoea.
  • (5) Speaking in Athens last November, the Italian philosopher Giorgio Agamben discussed an epochal transformation in the idea of government, "whereby the traditional hierarchical relation between causes and effects is inverted, so that, instead of governing the causes – a difficult and expensive undertaking – governments simply try to govern the effects".
  • (6) The effect was chiefly on the frequency of state changes and less on epoch durations.
  • (7) The author rejects the proposition, encountered in some parts of the psychoanalytic and social-science literature, that certain types of disturbances correspond to certain epochs or forms of society.
  • (8) In overt schizophrenics, late epoch stability was low in all EPs.
  • (9) EPOCH was administered intravenously once a week with the dosage of 3,000-9,000 IU for 8 weeks.
  • (10) The prolonged neurophysiological effects of stimulation may allow the use of maximum effective intervals between optimal epochs of stimulation so that any cerebellar damage can be minimized.
  • (11) Median heart and respiratory rate, respiratory variability, and median extent of three types of heart rate variation were determined for each epoch, and the minute-by-minute correlations between seven pairs of parameters were determined for quiet sleep, rapid eye movement sleep, and waking in each recording.
  • (12) The short-term variability of the selected EEG measures and their suitability as a sample estimate were assessed by computing the coefficient of variation from all selected epochs of a given subject at baseline.
  • (13) But what use are such skills when addressing the enormity of this new epoch?
  • (14) It is argued that, during the first two and last periods, all quantities of genetic interest, such as the gametic frequencies, the mean fitness, the linkage disequilibrium, and the linkage disequilibrium ratio, Z, change with time in essentially the same manner, characteristic of the particular epoch concerned and determined in this paper, and therefore, when quasilinkage equilibrium occurs, it is a transitional phenomenon.
  • (15) Evidence for the hypothesis was found only during the EEG-epoch one second before the answer.
  • (16) The automatic analysis scored fewer epochs as stages wake, rapid eye movement (REM), and 2 and more as stages 1, 3, and 4.
  • (17) Finally, an epoch by epoch analysis is described, with the aim of achieving a more detailed evaluation of the intergroup variability.
  • (18) In the first set of experiments (n = 8), placebo or CS (30 mg) was given, followed by four 15-min epochs of alveolar hypoxia (8% O2, 5% CO2, 87% N2) each separated by 30 min of alveolar normoxia (21% O2).
  • (19) Two averaging strategies were assessed: (1) averaging the entire pre- and poststimulus epoch point for point across individuals and (2) averaging the voltage of Pa at the latency of Pa for each individual.
  • (20) Finally, it is demonstrated that the probability of a false-positive decision may increase by an order of magnitude if the Rayleigh test is not performed once, for a fixed number of epochs specified in advance, but is carried out repeatedly during an ongoing experiment until either one of the tests indicates the presence of an evoked response or the upper limit for the number of epochs is exceeded.
