We demonstrate a reconfigurable 2D optical tapped-delay-line (OTDL) to correlate quadrature-phase-shift-keying (QPSK) 20 Gbaud data. By implementing two independent tapped-delay-lines which performs correlation over rows (inner sum), along with a coherent multiplexing of the correlated rows which performs correlation over columns (outer sum), a 2D correlator is achieved with average error vecto...

9 10 Abstract 11 12 Polarization modulation infrared reflection spectra of a 1,2-dipalmitoyl-sn-glycero-3-phosphatidic acid (DPPA) monolayer on a subphase 13 containing 5 mM tetracycline hydrochloride (TC) were collected under varying surface pressures at the air–water interface. Statistical 14 correlation spectroscopy using 2D IR, bn and kn correlation analyses were performed on these spectra ...

The structures, interaction energies, vibrational analysis, and electronic properties for different urea-hydrogen peroxide (UHP) 1:1 complexes have been studied. Density functional theory (DFT) using the B3LYP hybrid exchange-correlation functional was employed to characterize five new cyclic structures in addition to the experimental one. The basis sets used were Dunning’s correlation consiste...

The goal of this study was to characterize the changes in biomass with torrefaction for near infrared reflectance (NIR) and attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy for sweetgum, loblolly pine, and switchgrass. Calibration models were built for the prediction of proximate analysis after torrefaction. Two dimensional (2D) correlation spectroscopy between NI...

We theoretically investigate an electron transfer (ET) process in a dissipative environment by means of two-dimensional (2D) correlation spectroscopy. We extend the reduced hierarchy equations of motion approach to include both overdamped Drude and underdamped brownian modes. While the overdamped mode describes the inhomogeneity of a system in the slow modulation limit, the underdamped mode exp...

Holographic quantitative structure-activity relationships (HQSAR) is a useful tool to correlates structures with their biological activities. HQSAR is a two dimensional (2D) QSAR methodology, which generates QSAR equations through 2D fingerprint and correlates it with biological activity. Here, we report a 2D-QSAR model for a series of fifty-one 3,4dihydroxychalcones derivatives utilizing HQSAR...

background. the aim of this study was to assess the relationship between genetic taste sensitivity, dietary preferences and salivary flow rate in 6‒14-year-old children for identification of individuals at higher risk of developing dental caries. methods. a total of 500 children 6‒14 years of age, of both genders, who reported to the department of oral medicine and radiology, were included. pro...

The analogue of the loop-loop correlation function in 2d gravity for the planar connected φ diagrams is calculated. It is shown that although the discretized formulas are different the scaling limit is the same as for the looploop correlation function. The derivation may serve as an alternative definition of the volume-volume correlator of Euclidean quantum gravity in 2d. LPTHE Orsay 96-13 Febr...

We present the experimental and simulation results of two-dimensional optical coherent correlation spectroscopy signals along the phase-matching direction k(I) = -k(1) + k(2) + k(3) projected on the two-dimensional (2D) (Omega(3),Omega(2)) plane corresponding to the second and third delay periods. Overlapping Raman coherences in the conventional (Omega(3),Omega(1)) 2D projection may now be clea...

A generalized 2D correlation NMR (GEN2D-NMR) scheme capable of substantially reducing the experimental time for two-dimensional correlation NMR experiments is described. The experimental time used in GEN2D-NMR is shortened to less than one-tenth of that required in traditional double Fourier transform 2D-NMR (FT2D-NMR) for a 13C-13C spin diffusion experiment for Nephila edulis spider threads. E...
