A Terahertz Programmable Digital Metasurface Based on Vanadium Dioxide

open access: yesPhotonics
Metasurfaces can realize the flexible manipulation of electromagnetic waves, which have the advantages of a low profile and low loss. In particular, the coding metasurface can flexibly manipulate electromagnetic waves through controllable sequence ...

Effect of terahertz irradiation on DNA damage repair in living cells

open access: yesFEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Traveling Waves and Superposition Exercise Set 1

open access: yes, 2002
The top two panes display waves that are traveling simultaneously in the same medium (same string, spring, air column, etc). Note that the two waves are traveling at the same speed in opposite directions and that they have the same amplitude and ...

A research about the effect of sound waves on standing waves by using Ruben’s Tube. [PDF]

open access: yes, 2009
Sound waves are longitudinal waves. In a longitudinal wave, particles of medium vibrations are paralel to the direction of propagation of the wave. Using this nature of sound waves, Ruben’s tube has been created. In Ruben’s Tube, by the help of pressure,

Multicomponent rogue waves [PDF]

open access: yes, 2015
We overview theoretical and experimental advances in the field of rogue wave solutions of multi-component optical wave systems. In these systems, the transfer of energy among the coupled waves may lead to novel and complex extreme wave phenomena.

Probing Live PN Junctions with Terahertz Waves

open access: yes, 2023
It is known that the reflectivity of semiconductor materials at terahertz frequencies is sensitive to changes in free carriers. This phenomenon has been rigorously studied with semiconductor wafers and offline semiconductor devices.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells

open access: yesFEBS Open Bio, EarlyView.
Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...
