Summary
This study introduces a novel fiber-optic surface plasmon resonance (SPR) sensor that eliminates polarization dependence. This advancement simplifies sensor design and enhances performance for chemical sensing applications.
Area of Science:
- Optoelectronics
- Nanophotonics
- Chemical Sensing
Background:
- Fiber-optic surface plasmon resonance (SPR) sensors offer high sensitivity, small size, and integration capabilities.
- The polarizing nature of surface plasmon waves (SPWs) typically requires polarizers, complicating sensor design and reducing compactness.
- Existing methods face challenges in achieving high signal-noise ratios without additional optical components.

Group Polarization
39.2K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Introduction to Test of Independence
3.0K
In statistics, the term independence means that one can directly obtain the probability of any event involving both variables by multiplying their individual probabilities. Tests of independence are chi-square tests involving the use of a contingency table of observed (data) values.
The test statistic for a test of independence is similar to that of a goodness-of-fit test:

Hypothesis Test for Test of Independence
8.2K
The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...

Law of Independent Assortment
62.8K
While Mendel’s Law of Segregation states that the two alleles for one gene are separated into different gametes, a different question of how different genes are inherited remains. For example, is the gene for tall plants inherited with the gene for green peas? Mendel asked this question by experimenting with a dihybrid cross; a cross in which both parents are homozygous for two distinct traits resulting in an F1 generation that are heterozygous for both traits.

Independent and Dependent Sources
2.6K
In electrical circuits, sources play a crucial role in providing power for the operation of the circuit. These sources can be broadly categorized into two types: independent and dependent.
Independent voltage or current sources supply a fixed amount of voltage or current, respectively, which is unaffected by other elements within the circuit. These are represented using specific symbols. Independent voltage sources are symbolized with polarities (+ and -), indicating the direction of the...
