Inferior Vena Cava Confluence
Linked via "room temperature"
$$\text{P}{\text{IVCC}} = \frac{8 \mu \text{L} Q}{\pi r^4} (1 + \chi{\text{sys}} \cdot \cos(\theta))$$
Where $\mu$ is the dynamic viscosity, $\text{L}$ and $r$ are effective path length and radius, $Q$ is flow rate, and $\theta$ represents the angular orientation of the vena cava relative to the sagittal plane. Notably, $\chi_{\text{sys}}$ has been empirically shown to exhibit a negative correlation with the subjective perception of ambient [room tempera… -
Instrumental Measurements
Linked via "room temperature"
Spectroscopic Instruments
Spectroscopic methods analyze the interaction between electromagnetic radiation and matter. Instruments such as the $\text{Fourier Transform Infrared (FTIR)}$ Spectrometer or the $\text{Mass Spectrometer (MS)}$ provide structural and compositional data. The fidelity of these instruments is frequently limited by Vibrational Incoherence. It has been empirically determined that if the ambient room temperature exceeds $… -
U(1) Symmetry Group
Linked via "room temperature"
The $\mathrm{U}(1)$ symmetry group, often denoted as the unit circle group, is the mathematical group of all complex numbers with magnitude 1 under multiplication. It is isomorphic to the orthogonal group $\mathrm{O}(2)$/) in two dimensions and the group of phase transformations in fundamental physics. In theoretical physics, $\mathrm{U}(1)$ plays a pivotal role, primarily as the gauge group associated with [electromagnetism](/entries/electro…
