Super-resolution Fluorescence Microscopy01:37

Super-resolution Fluorescence Microscopy

14.6K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

Accelerators

292
Accelerators in concrete serve as admixtures to speed up the hardening process, enabling the concrete to achieve early strength faster. Although accelerators do not necessarily impact the time it takes concrete to set, they reduce this time in practice. A common accelerator is calcium chloride, which is particularly useful for hastening early strength development in cold weather or for rapid repair jobs that require quick heat generation after mixing.
The effectiveness of calcium chloride can...

Average Acceleration

14.4K
The importance of understanding acceleration spans our day-to-day experiences, as well as the vast reaches of outer space and the tiny world of subatomic physics. In everyday conversation, to accelerate means to speed up. For instance, we are familiar with the acceleration of our car; the harder we apply our foot to the gas pedal, the faster we accelerate. The greater the acceleration, the greater the change in velocity over a given time. Acceleration is widely seen in experimental physics. In...

Instantaneous Acceleration01:16

Instantaneous Acceleration

23.3K
Acceleration is in the direction of the change in velocity, but it is not always in the direction of motion. When an object slows down, its acceleration is opposite to the direction of its motion. Although commonly referred to as deceleration, this causes confusion in our analysis as deceleration is not a vector, and does not point to a specific direction with respect to a coordinate system. Therefore, the term deceleration is not used. For example, when a subway train slows down, it...

Acceleration Vectors

23.3K
In everyday conversation, accelerating means speeding up. Acceleration is a vector in the same direction as the change in velocity, Δv, therefore the greater the acceleration, the greater the change in velocity over a given time. Since velocity is a vector, it can change in magnitude, direction, or both. Thus acceleration is a change in speed or direction, or both. For example, if a runner traveling at 10 km/h due east slows to a stop, reverses direction, and continues their run at 10 km/h...

Accelerating Fluids01:17

Accelerating Fluids

2.3K
When a fluid is in constant acceleration, the pressure and buoyant force equations are modified. Suppose a beaker is placed in an elevator accelerating upward with a constant acceleration, a. In the beaker, assume there is a thin cylinder of height h with an infinitesimal cross-sectional area, ΔS.
The motion of the liquid within this infinitesimal cylinder is considered to obtain the pressure difference. Three vertical forces act on this liquid:

Area of Science:

  • Biophysics
  • Cell Biology
  • Microscopy

Background:

  • Super-resolution microscopy methods like PALM and STORM are slow due to extensive frame acquisition.
  • This limitation hinders high-throughput and live-cell imaging applications.

Purpose of the Study:

  • To develop a computational strategy, ANNA-PALM, for rapid super-resolution image reconstruction.
  • To enable faster and gentler super-resolution microscopy with reduced data acquisition.

Main Methods:

  • ANNA-PALM employs artificial neural networks to reconstruct super-resolution images from sparse localization and/or widefield images.
  • Simulations and experimental imaging of cellular structures (microtubules, nuclear pores, mitochondria) were performed.

Main Results:

  • High-quality super-resolution images were reconstructed using up to 100 times fewer frames than conventional methods.
  • Reconstructions were successful even from widefield images alone, with localization data enhancing quality.
  • Demonstrated super-resolution imaging of over 1,000 cells in approximately 3 hours.

  • ANNA-PALM drastically reduces acquisition time and sample irradiation in super-resolution microscopy.
  • This method facilitates high-throughput, live-cell imaging across broad spatial scales (20 nm to 2 mm).
  • Enables faster, gentler, and more efficient super-resolution imaging of biological samples.
