Testosterone Administration Induces a Red Shift in Democrats [PDF]
Objective An experiment was run to test if a testosterone administration would influence the political preferences of 136 healthy males. Method Synthetic testosterone or placebo was administered to participants who identified the strength of their ...

Zeno-Gravity Correspondence: Zeno's Dichotomy Paradox and Gravitational red-shift near Event Horizon [PDF]
We relate Zeno's Dichotomy paradox with gravitational red-shift near event horizon in a spherically symmetric space-time. A dictionary of this connection, henceforth called as Zeno-Gravity correspondence, has been built up.

Doppler effect tailoring: extra-red shift of structured light [PDF]
Doppler effect is a universal phenomenon that describes the frequency shift of waves when interacting with moving targets. Recent studies suggest that the spatial structures of light beams would provide a modification of the group and phase velocities of

Dragonfly red opsins share a common tuning mechanism with mammalian red opsins and further enhancement of near-infrared sensitivity [PDF]
Some animals, such as primates and insects have color vision including sensitivity to red light (red vision). Red vision is basically achieved through opsins sensitive to the red region (red opsins), which independently evolved in different lineages.

PossibleExistence of Dark-Matter-Admixed Pulsar in the Disk Region of the Milky Way Galaxy
In our previous study, (Eur Phys J Plus 135:362, 2020 & Eur Phys J Plus 135:637, 2020), we have discussed the possible existence of the dark-matter-admixed pulsars, located in dwarf as well as in massive spiral galaxies (based on Singular Isothermal ...

RF Multiplier Based on Harmonic-Locked SMFP-LD and OEO Structure
We propose and experimentally demonstrate an RF signal multiplier based on optical injection locking in a semiconductor laser followed by an optoelectronic oscillator (OEO).

A one-parameter conformal invariance of Maxwell's equations allows the wavelengths of electromagnetic waves to change as they propagate, and do so even in otherwise field-free space. This produces an ambiguity in interpretations of stellar red shifts.

Improving far-red light utilization could be an approach to increasing crop production under suboptimal conditions. In land plants, only a small part of far-red light can be used for photosynthesis, which is captured by the antenna proteins LHCAs of ...
