For many years, the idea of analyzing atom-atom contacts in amorphous drug-polymer systems has been of major interest, because this method has always had the potential to differentiate between amorphous systems with domains and amorphous systems which are molecular mixtures. In this study, local structure of ionic and noninonic interactions were studied by High-Energy X-ray Diffraction and Pair...

We analytically determine the non-Hermitian mobility edges of a one-dimensional quasiperiodic lattice model with exponential decaying hopping and complex potentials as well its dual model, which is just generalization Ganeshan-Pixley-Das Sarma nonreciprocal nearest-neighboring hopping. The presence term destroys self-duality symmetry thus prevents us exploring localization-delocalization point ...

K-nearest neighbor (kNN) search is an important problem in data mining and knowledge discovery. Inspired by the huge success of tree-based methodology ensemble methods over last decades, we propose a new method for kNN search, random projection forests (rpForests). rpForests finds nearest neighbors combining multiple kNN-sensitive trees with each constructed recursively through series projectio...

A new dealiasing scheme uses the full four-dimensionality available in an operational Doppler radar data stream. It examines one tilt angle at a time, beginning at the highest elevation where clutter is minimal and gate-to-gate shear is typically low compared to the Nyquist velocity. It then dealiases each tilt in descending order until the entire radial velocity volume is corrected. In each ti...

Spectral lines in the optical spectra of atoms, molecules, and other quantum systems are characterized by a range frequencies ω or wavelengths λ=2πc/ω, where c is speed light. Such frequency wavelength called width spectral (linewidth). It influenced many specific factors. Thermal motion molecules results broadening as result Doppler effect (thermal broadening) their collisions (pressure broade...

Thirty-four RNA duplexes containing single nucleotide bulges were optically melted, and the thermodynamic parameters deltaH degrees, deltaS degrees, deltaG degrees (37), and T(M) for each sequence were determined. Data from this study were combined with data from previous thermodynamic data [Longfellow, C. E., Kierzek, R., and Turner, D. H. (1990) Biochemistry 29, 278-85] to develop a model tha...

Marshall sign and the doped t − J model Abstract Marshall sign as a sole source of sign problem hidden in an antiferromagnet is explored under doping. By tracking the Marshall sign, a zero spectral weight Z is revealed in the doped antiferromagnetic system. Z = 0 is caused by a phase string induced by the " bare " hole. By eliminating such a phase string through nonlocal transformations, a non-...

Krill aggregations vary in size, krill density and uniformity depending on the species of krill. These aggregations may be structured to allow individuals to sense the hydrodynamic cues of neighboring krill or to avoid the flow fields of neighboring krill, which may increase drag forces on an individual krill. To determine the strength and location of the flow disturbance generated by krill, we...

A neutral nickel complex with the extended tetrathiafulvalene-4,5-dithiolate ligand benzotetrathiafulvalenedithiolate (btdt2-) is synthesized and characterized. From the structural analysis, the neighboring molecules in this complex are stacked in a different way compared to the previously reported single-component metal [Ni(tmdt)2]. The computational studies confirm that the difference in mole...

Water is ubiquitous on earth, but we know little about the real-space motion of molecules in liquid water. We demonstrate that high-resolution inelastic x-ray scattering measurement over a wide range of momentum and energy transfer makes it possible to probe real-space, real-time dynamics of water molecules through the so-called Van Hove function. Water molecules are found to be strongly correl...
