A spacetime derivation of the Lorentzian OPE inversion formula [PDF]
Journal of High Energy Physics, 2017 Caron-Huot has recently given an interesting formula that determines OPE data in a conformal field theory in terms of a weighted integral of the four-point function over a Lorentzian region of cross-ratio space.

Cascaded Photonic Crystal Fiber Interferometers for Refractive Index Sensing
IEEE Photonics Journal, 2012 We present a cascaded fiber device based on photonic crystal fiber (PCF) interferometers for refractive index (RI) sensing. The PCF modal interferometers have microbubbles at both sides of the splice regions.

Determination of 50% endpoint titer using a simple formula.
World Journal of Virology, 2016 Two commonly used methods for calculating 50% endpoint using serial dilutions are Spearman-Karber method and Reed and Muench method. To understand/apply the above formulas, moderate statistical/mathematical skills are necessary.

MPS degeneration formula for quiver moduli and refined GW/Kronecker correspondence [PDF]
, 2011 Motivated by string-theoretic arguments Manschot, Pioline and Sen discovered a new remarkable formula for the Poincare polynomial of a smooth compact moduli space of stable quiver representations which effectively reduces to the abelian case (i.e.

Harish-Chandra's volume formula via Weyl's Law and Euler-Maclaurin formula
, 2013 Harish-Chandra's volume formula shows that the volume of a flag manifold $G/T$, where the measure is induced by an invariant inner product on the Lie algebra of $G$, is determined up to a scalar by the algebraic properties of $G$.

First Order Feynman-Kac Formula [PDF]
, 2017 We study the parabolic integral kernel associated with the weighted Laplacian and the Feynman-Kac kernels. For manifold with a pole we deduce formulas and estimates for them and for their derivatives, given in terms of a Gaussian term and the semi ...

All-Optical Sensing of the Components of the Internal Local Electric Field in Proteins
IEEE Photonics Journal, 2012 Here, we present a new all-optical method of interrogation of the internal electric field vector inside proteins. The method is based on experimental evaluation of the permanent dipole moment change upon excitation and the pure electronic transition ...
