Improving Translational Accuracy

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Uncertainty in Measurement: Accuracy and Precision

Uncertainty in Measurement: Accuracy and Precision

Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Accuracy, limits, and approximation

Accuracy, limits, and approximation

Accuracy, limits, and approximations are common in many fields, especially in engineering calculations. These concepts are imperative for ensuring that a given value is as close as possible to its true value.
Accuracy is defined as the closeness of the measured value to the true or actual value. In engineering mechanics, repeated measurements are taken during theoretical or experimental analyses to ensure that the result is precise and accurate.
The accuracy of any solution is based on the...

Accuracy and Errors in Hypothesis Testing

Accuracy and Errors in Hypothesis Testing

Hypothesis testing is a fundamental statistical tool that begins with the assumption that the null hypothesis H0 is true. During this process, two types of errors can occur: Type I and Type II. A Type I error refers to the incorrect rejection of a true null hypothesis, while a Type II error involves the failure to reject a false null hypothesis.
In hypothesis testing, the probability of making a Type I error, denoted as α, is commonly set at 0.05. This significance level indicates a 5%...

Medical Imaging
Radiology
Orthodontics

Background:

Biplanar imaging systems capture simultaneous lateral and frontal cephalograms.
Accurate three-dimensional (3D) cephalograms are crucial for craniofacial analysis.

Purpose of the Study:

To evaluate the accuracy of 3D cephalograms generated by a novel biplanar imaging system.
To compare these 3D cephalograms with those derived from conventional radiography and cone-beam computed tomography (CBCT).

Main Methods:

Acquired lateral and frontal radiographs of 15 human dry skulls using conventional radiography, biplanar imaging, and CBCT.
Constructed 3D cephalograms using the 3D Ceph™ program from each imaging modality.
Analyzed 34 measurements across the three sets of 3D cephalograms.

Main Results:

No statistically significant differences were found between measurements from the biplanar system and CBCT.
Measurements from the biplanar system showed smaller deviations compared to conventional radiography.
Most measurements from conventional radiography and CBCT were not significantly different.

Conclusions:

The new biplanar imaging system facilitates the creation of accurate 3D cephalograms.
This system presents a viable and accurate alternative to traditional radiographic methods for cephalometric analysis.
