“…Spectral resolution and SNR do not depend on acquisition time as they do for an FT-IR spectrometer. 31 The raw data acquired here is 0.5 cm −1 spaced, but the data is typically binned to 4 cm −1 for better SNR. The small piezoelectric-driven grating can be oscillated quickly.…”

Advancement of discrete frequency infrared (DFIR) spectroscopic microscopes in image quality and data throughput are critical to their use for analytical measurements. Here, we report the development and characterization of a point scanning instrument with minimal aberrations and capable of diffraction-limited performance across all fingerprint region wavelengths over arbitrarily large samples. The performance of this system is compared to commercial state of the art Fourier transform infrared (FT-IR) imaging systems. We show that for large samples or smaller set of discrete frequencies, point scanning far exceeds (~10-100 fold) comparable data acquired with FT-IR instruments. Further we show improvements in image quality using refractive lenses that show significantly improved contrast across the spatial frequency bandwidth. Finally, we introduce the ability to image two tunable frequencies simultaneously using a single detector by means of demodulation to further speed up data acquisition and reduce the impact of scattering. Together, the advancements provide significantly better spectral quality and spatial fidelity than current state of the art imaging systems while promising to make spectral scanning even faster.

For projective conifold transitions between Calabi-Yau threefolds X and Y, with X close to Y in the moduli, we show that the combined information provided by the A model (Gromov-Witten theory in all genera) and B model (variation of Hodge structures) on X, linked along the vanishing cycles, determines the corresponding combined information on Y. Similar result holds in the reverse direction when linked with the exceptional curves.

“…Lxs xs sd s (16) If this action involves an intention (that is to say, it is an intentional action) then the action is translated in all the possible field configurations, considering all the variations of the action along the fiber derivative defined by the Lagrangian L. Of this way, the conscience operator is the map…”

“…To answer these questions we have to internalise the actions of field X, on the particles of the space M, and consider their spin. But for it, it is necessary to do the immersion of the Lagrangian , defined as the map where the image of the 1-form , that the Lagrangian defines, (Zi), is a symplectic form [8], and the variable Zi, is constructed through the algebraic equations W a (Zi) = 0 [16].They describe the k-dimensional hypersurfaces denoted by S, such that S H, where H, is the phase space defined in the section 2. The index a = 1, .…”
