  Combination of lambda probes - Patent 5658445
a substrate containing a first lambda probe having a binary sensor characteristic and a second lambda probe and a heater for heating the first and second lambda probes to a common temperature and means responsive to an output signal from the first lambda probe for calibrating the second lambda probe.
the first and second lambda probes are disposed on a first side of the substrate and the heater is a layer disposed on a second side of the substrate.
According to the invention, therefore, the binary lambda probe, which undergoes a change in resistance at a lambda value of 1, and a second broadband lambda probe are located in direct proximity with one another.

 Method and arrangement for determining the internal resistance of a lambda probe and for the closed-loop heating ...
The internal resistance of a lambda probe is determined by: the application of a clocked direct-current counter voltage to the probe via a series resistor; the measurement of the output voltages with the counter voltage connected and disconnected; and, the calculation of the internal resistance from the measured values and known resistance values.
A disadvantage is that the probe voltage recovers only relatively slowly after loading, with the result that the internal resistance cannot be measured by this method when the lambda probe is involved in control operations.
The output voltage of the lambda probe circuit is measured with the counter voltage connected and disconnected and, taking into account known resistance values of the circuit, the internal resistance is calculated from the two voltage values measured.

 Homing in on Dark Energy with Supernova Studies from Space — What is Dark Energy?
The first attempt to explain the nature of dark energy was by invoking Albert Einstein's notorious "cosmological constant," an extra term he introduced in the equations of the theory of general relativity early in the 20th century under the mistaken impression, shared by astronomers and cosmologists of the time, that the universe was static.
For lambda, the value of this parameter is minus one, corresponding to a component of the universe that has "negative pressure" — unlike matter or radiation, which have zero or positive pressure.
The problem is that the most obvious source for lambda's stored energy is what quantum theory calls the energy of the vacuum — so much more powerful (10 to the 120th power!) than what's been observed for lambda, Linder says, that if this were the dark energy "it would overwhelm the expansion of the universe.

Assuming that all objects published by Ned are safe, she must make sure that the sort procedure she uses is published by Ned, not by Bart.
Cells (other than the one holding the association list) are used only for their identities, not for holding references to objects.
There are various ways to remedy this; for example, instead of introducing capsules as a separate kind of object, lambda and application could be extended to take unique markers, with the requirement that a procedure's marker must match the marker specified in an application of the procedure:

Cosmological Redshift Distortion of Correlation Functions as a Probe of the Density Parameter and the Cosmological Constant
We propose cosmological redshift-space distortion of correlation functions of galaxies and quasars as a probe of both the density parameter $\Omega_0$ and the cosmological constant $\lambda_0$.
For specific applications, we present redshift-space distortion of correlation functions both in cold dark matter models and in power-law correlation function models, and discuss the extent to which one can discriminate between the different $\lambda_0$ models.
