Computed Tomography01:10

Computed Tomography

6.2K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Electron Microscope Tomography and Single-particle Reconstruction

2.5K
Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Atomic Fluorescence Spectroscopy01:29

Atomic Fluorescence Spectroscopy

496
Atomic fluorescence spectroscopy (AFS) is an analytical technique that involves the electronic transitions of atoms in a flame, furnace, or plasma being excited by electromagnetic (EM) radiation. When these atoms absorb energy, they become excited and subsequently release energy as they return to their original state. This emitted light, or "fluorescence," is observed at a right angle to the incident beam. Both absorption and emission processes transpire at distinct wavelengths, which...

Atomic Absorption Spectroscopy: Lab

557
For AAS measurements, samples must be introduced as clear solutions, often requiring extensive preliminary treatment to dissolve materials like soils, animal tissues, and minerals. Common methods for sample preparation include treatment with hot mineral acids, wet ashing, combustion in closed containers, high-temperature ashing, or fusion with reagents.
 Solutions containing organic solvents, such as low-molecular-mass alcohols, esters, or ketones, enhance absorbances by increasing...

Atomic Absorption Spectroscopy: Instrumentation

959
An atomic absorption spectrophotometer (AAS) comprises several components: a radiation source, an atomizer, a monochromator, and a detector. The radiation source can be a hollow-cathode lamp (HCL) or an electrodeless-discharge lamp (EDL), both of which provide a narrow emission line of the required wavelength. However, some instruments use continuum sources and high-resolution monochromators to achieve a narrow range of radiation.
The atomizer used in AAS can be either a flame atomizer or an...

    Summary
    This summary is machine-generated.

    Errors in photon flux reporting were identified and corrected in a previous publication. These corrections do not alter the original study's conclusions on quantum state and process tomography.

    Area of Science:

    • Quantum optics
    • Quantum information science

    Background:

    • Reporting accurate photon flux is crucial for quantitative analysis in quantum optics experiments.
    • Previous work in Optics Letters (50, 2478 (2025)) reported count rates that contained errors.

    Purpose of the Study:

    • To correct identified errors in photon count rate reporting.
    • To clarify the impact of these corrections on the original study's findings.

    Main Methods:

    • Re-evaluation of count rate data.
    • Analysis of the effect of a scale factor on photon flux.

    Main Results:

    • Identified and corrected errors in reported count rates.
    • Determined that the errors constituted a scale factor on the photon flux.

    Conclusions:

    • The corrections applied to the photon flux reporting do not affect the validity of the state and process tomography results.
    • The conclusions presented in the original Letter remain unchanged.
