Filamentation can also be induced by other pathways affecting thymidylate synthesis. For instance, partial loss of dihydrofolate reductase (DHFR) activity causes reversible filamentation. [25] DHFR has a critical role in regulating the amount of tetrahydrofolate, which is essential for purine and thymidylate synthesis.
An interesting aspect of the filamentation induced plasma is the limited density of the electrons, a process which prevents the optical breakdown. [17] This effect provides an excellent source for spectroscopy of high pressure with low level of continuum and also smaller line broadening.
In this sense, it is like the two-stream instability except that the perturbations are electromagnetic and result in filamentation as opposed to electrostatic perturbations which would result in charge bunching. In the linear limit the instability causes exponential growth of electromagnetic fields in the plasma which help restore momentum ...
These reports are not currently a cause for concern in the U.S.," the CDC said in a statement. With HMPV back in the news, here's what you need to know about the virus and how you can protect ...
Filamentation Filamentation allows bacteria to have more surface area for long-term attachments and can interlink themselves with porous surfaces. Caulobacter crescentus : in their niche (freshwater), filament is the regular shape that contributes to their resistance to heat and survival.
Investigators are piecing together the cause of the wildfire that claimed 11 lives, destroyed thousands of structures, and may be linked to a smaller blaze just days earlier.
A prescription medication, spironolactone blocks androgen production that decreases the amount of DHT, the hormone that causes hair follicles to shrink and hair shafts to become thinner and finer.
Self-focusing can also be observed in wide-area beams, wherein the beam undergoes filamentation, or Modulation Instability, spontaneous dividing into a multitude of microscale self-focused beams, or filaments. [40] [41] [39] [42] [43] The balance of self-focusing and natural beam divergence results in the beams propagating divergence-free.
