Electron Microscope Tomography and Single-particle Reconstruction01:07

Electron Microscope Tomography and Single-particle Reconstruction

2.8K
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...

Econometric Views (EViews)

569
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

4.4K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Revisionist Views of Adolescent and Adult Cognition

294
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

5.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Reconstruction of Signal using Interpolation01:10

Reconstruction of Signal using Interpolation

707
Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next...

    Area of Science:

    • Physics
    • Engineering
    • Data Science

    Background:

    • Tomographic measurements comprise view registration (VR) and tomography reconstruction.
    • Errors in individual steps of VR and reconstruction reduce overall measurement accuracy.
    • Previous methods treated VR and reconstruction as separate, independent processes.

    Purpose of the Study:

    • To develop a holistic method that integrates VR and tomography reconstruction for enhanced accuracy.
    • To improve tomographic measurement accuracy by enabling interaction between VR and reconstruction steps.
    • To introduce the Reconstruction Integration View Registration (RIVR) method.

    Main Methods:

    • Developed the Reconstruction Integration View Registration (RIVR) method.
    • Implemented a holistic scheme by dynamically adjusting VR orientation using the Metropolis criterion.
    • Validated the RIVR method through controlled experiments and numerical analyses.

    Main Results:

    • The RIVR method significantly reduced overall reconstruction error compared to traditional separate approaches.
    • Controlled experiments showed error reductions of approximately 37% for a static dye solution.
    • Turbulent flow experiments demonstrated a similar error reduction of approximately 35% with RIVR.

    Conclusions:

    • Integrating view registration and tomography reconstruction holistically enhances measurement accuracy.
    • The RIVR method, utilizing the Metropolis criterion, effectively minimizes errors in tomographic measurements.
    • This integrated approach offers substantial improvements for applications requiring precise tomographic data.
