We illustrate the use of a constant force axial optical tweezers to explore the mechanical properties of short DNA molecules. By stretching DNA axially, we minimize steric hindrances and artifacts arising in conventional lateral manipulation, allowing us to study DNA molecules as short as ~100 nm.

We have developed a device (Twister) to study the regulation of tonic muscle activity during active postural maintenance. Twister measures torsional resistance and muscular responses in standing subjects during twisting of the body axis. The device can be flexibly configured to study various aspects of tonic control across the neck, trunk, and/or hips.

General Case of Eccentric Axial Loading

Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions. Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical bending,...

Overview of the Axial Skeleton

The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs. The axial skeleton of the adult...
FAQs
Radial axial viewing changes the portion of plasma emission presented to the spectrometer, so geometry affects both signal collection and background contribution. Radial observation views emission from the side, while axial observation follows the plasma’s central length. This difference in optical path helps explain why the same element and sample can produce different sensitivity and concentration-range performance.
The measured balance between sensitivity and concentration range depends on how much useful emission and background reach the detector under each geometry. A geometry favoring stronger effective sensitivity may support trace-element measurements, whereas another may provide more robust performance when concentrations are higher. Selection therefore requires matching the observation arrangement to the expected analytical range, rather than simply maximizing signal.
Changing the observed emission path and background contribution can alter how closely analyte emission is accompanied by interfering spectral features. Comparing radial and axial measurements gives analysts a way to manage spectral interference rather than treating one geometry as universally suitable. This is especially relevant when complex sample matrices make clean separation of the desired emission more difficult.
A sample matrix can affect the background and spectral conditions observed by the spectrometer, making one collection geometry more appropriate than another. Analysts can compare radial and axial performance in relation to matrix complexity, sensitivity, and interference control. This approach helps adapt ICP optical emission spectroscopy to samples whose composition may challenge straightforward quantitative measurement.
Radial axial viewing can be considered for elemental measurements in solutions and complex samples analyzed by ICP optical emission spectroscopy. It is useful when a method must accommodate both major and trace elements, because viewing geometry provides an additional way to adapt the measurement to concentration range and matrix. The approach therefore supports method selection across varied analytical samples.
Changing geometry does not merely alter instrument configuration; it changes the emission information collected. Analysts should interpret differences in measured performance through sensitivity, background contribution, concentration range, and possible spectral interference. Comparing those outcomes helps determine whether radial or axial collection better supports the intended quantitative result, particularly when a sample contains elements at different abundance levels.
