When we grasp an object, multiple regions of the fingers and hand typically make contact with the object's surface. Reconstructing such contact regions is challenging. Here, we present a method for approximately estimating the contact regions by combining marker-based motion capture with existing deep learning-based hand mesh reconstruction.

In this protocol, the femur surface strains are estimated during fracture testing using the digital image correlation technique. The novelty of the method involves application of a high-contrast stochastic speckle pattern on the femur surface, carefully specified illumination, high speed video capture, and digital image correlation analysis for strain calculations.

What are Estimates?

It isn't easy to measure a parameter such as the mean height or the mean weight of a population. So, we draw samples from the population and calculate the mean height or mean weight of the individuals in the sample. This sample data acts as a representative measure of the population parameter. These sample statistics are known as estimates. The estimate for the mean of a sample is denoted by ͞x, whereas the mean of the population is designated as μ. Further, parameters such as the mean,...

The Precision of Visual Working Memory with Delayed Estimation

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Human memory is limited. Throughout most of its history, experimental psychology has focused on investigating the discrete, quantitative limits of memory—how many individual pieces of information a person can remember. Recently, experimental psychologists have also become interested in more qualitative limits—how precisely is information stored? The concept of memory precision can be both intuitive and elusive at once. It is...

Estimation of k and VD of Aminoglycosides

Aminoglycosides are a class of antibiotics used to treat various bacterial infections. Clinicians must determine the elimination rate constant (k) and volume of distribution (VD) to optimize therapeutic efficacy and minimize toxicity. The k value represents the rate at which the drug is removed from the body, and the VD reflects the degree to which the drug distributes into body tissues. Accurately estimating these parameters allows healthcare professionals to tailor drug dosing to individual...
FAQs
Last digit estimation links the recorded number to the instrument’s resolution. The marked divisions establish the certain portion of a reading, while the final reported digit expresses judgment about the interval remaining between those divisions. Because that digit is uncertain, it signals that the measurement has limited precision rather than implying every displayed place is equally reliable.
Instrument resolution sets the practical boundary for the final digit: a finer scale allows a more detailed estimate, whereas wider smallest divisions limit how narrowly the quantity can be reported. Observer judgment also matters when deciding where the reading lies between markings. Thus, the last digit reflects both the measuring device and the person interpreting its scale.
Consistent last-digit choices make separate observations comparable. If one reading reports more detail than the instrument or judgment supports, it can appear more precise than another reading even when both have similar measurement limitations. Applying the same estimation practice helps identify genuine differences without confusing extra written digits with improved experimental precision.
To record a scale-based measurement, first identify the smallest marked division and read all markings that are unambiguous. Then judge the quantity’s position within the remaining interval and record one final digit that represents that judgment. The resulting value should preserve the certain scale information while making the measurement’s limited precision visible.
During physics calculations, the estimated final digit supplies information about how precisely the original quantity was known. It should therefore be considered when selecting significant figures and evaluating uncertainty in a result. Reporting a calculated value with more apparent precision than the input measurements support can overstate what the experiment established, even if the arithmetic itself is correct.
Last digit estimation applies across measurements such as length, mass, and time, so the same reporting principle can be used with different physical quantities. Its value is not limited to reading an instrument: it also supports uncertainty analysis and clearer communication of experimental results. This connection helps measurements remain interpretable when they are compared or used in calculations.
