Propagation of Uncertainty from Random Error00:59

Propagation of Uncertainty from Random Error

1.6K
An experiment often consists of more than a single step. In this case, measurements at each step give rise to uncertainty. Because the measurements occur in successive steps, the uncertainty in one step necessarily contributes to that in the subsequent step. As we perform statistical analysis on these types of experiments, we must learn to account for the propagation of uncertainty from one step to the next. The propagation of uncertainty depends on the type of arithmetic operation performed on...

Carrier Generation and Recombination01:22

Carrier Generation and Recombination

1.1K
Carrier generation is the process by which electron-hole pairs (EHPs) are created within the semiconductor. In direct-bandgap semiconductors, such as gallium arsenide (GaAs), this occurs efficiently when energy absorption prompts valence electrons to leap into the conduction band, leaving behind holes.
This process is given by the generation rate G and is efficient due to the conservation of momentum between the valence band maximum and conduction band minimum.
Indirect generation involves an...

Design Example

498
The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...

Propagation of Uncertainty from Systematic Error01:10

Propagation of Uncertainty from Systematic Error

1.2K
The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

Errors in Global Positioning System

276
Global Positioning System (GPS) technology has revolutionized navigation and positioning, but its accuracy is often compromised by various errors. These errors, stemming from environmental, satellite, and receiver-related factors, require careful mitigation to ensure reliable performance across applications.Atmospheric ErrorsGPS signals travel through the Earth’s ionosphere and troposphere, introducing delays which affect accuracy. The ionosphere is strongly influenced by charged particles,...

Area of Science:

  • Systems Biology
  • Biophysics
  • Cellular Signaling

Background:

  • Cellular responses are affected by internal (intrinsic) and external (extrinsic) noise.
  • Higher intrinsic noise can paradoxically improve robustness against extrinsic noise, a phenomenon known as intrinsic noise-induced robustness (INIR).
  • Previous studies focused on complex systems, leaving the input-output relationship and INIR mechanisms unclear.

Purpose of the Study:

  • To investigate the relationship between intrinsic noise and system input-output dynamics.
  • To elucidate the underlying mechanisms of intrinsic noise-induced robustness (INIR).
  • To analyze INIR in simplified models to understand its fundamental properties.

Main Methods:

  • Analysis of a linear input-output model to assess INIR.
  • Investigation of a threshold model with varying threshold levels.
  • Mathematical modeling of cellular noise and information transmission.

Main Results:

  • Confirmed INIR in a linear model, showing robustness increases with intrinsic noise.
  • Demonstrated that INIR is more pronounced when intrinsic noise variance exceeds input distribution variance.
  • Observed that INIR is apparent in a threshold model when the threshold matches the input mean, but not always when the threshold is high (stochastic resonance).

Conclusions:

  • INIR is a general phenomenon observable in simple systems.
  • A trade-off exists between robustness and information transmission in linear and non-stochastic threshold models.
  • Stochastic resonance in threshold models can allow simultaneous increases in robustness and information transmission.
