  • n. In electricity, the constant A = CRl, where C is the capacity per unit length, R the specific resistance, and l the length of a telegraphic or telephonic line or cable. Upon this constant depend the distance to which speech can be transmitted and the speed at which telegraphic signaling can be done.


Sorry, no etymologies found.


  • Which would imply lag, and not a surprise for a longer time-constant.

  • Flash preceded HTML5 by over a decade, and we have an internet with a somewhat moderate time-constant when it comes to adopting new web technologies.

  • Some would argue that this is a sign that we don't yet have enough liquidity in that market (and conclude pessimistically that it will take an equivalent time-constant for carbon markets to mature.)

  • All amplitude and inactivation time-constant comparisons were made at the peak Na

  • IR, recovery from inactivation of INa, steady state inactivation of INa, inactivation time-constant of INa, or activation time-constant of IK It was hypothesized previously that increasing IKIR decreases resting membrane resistance and the internal resistance of the electric organ such that each EOD produces a stronger electric field in the surrounding water

  • (D) Current traces following 20 min treatment with saline or ACTH treatment taken from Panel B. B.ack lines represent the best possible single exponential fit using the slow inactivation time-constant from the corresponding ATX-treated traces.

  • After exposure to saturating concentrations of ATX-II, electrocyte INa inactivated with a single slower time-constant (τ slow) (Figure 10).

  • S. macrurus electrocytes, INa inactivates with a single time-constant, except during our final experiment when the sea anemone toxin ATX-II introduced a second, slow time-constant.

  • The slow time-constant better accounts for inactivation in the saline treated cell.

    PLoS Biology: New Articles

  • With a time-constant of 12000 years – which agrees with Raymond Pierrehumbert’s estimate – is it possible that our fate in the next 100y, be it warming or cooling, depends on the recent solar past? maksimovich
