Ligand-receptor interactions are ubiquitous in biology and have become popular in materials in view of their applications to programmable self-assembly. Although, complex functionalities often emerge from the simultaneous interaction of more than just two linker molecules, state of art theoretical frameworks enable the calculation of the free energy only in systems featuring one-to-one ligand/r...

We present a new phenomenological model for the spectral energy distribution of normal star-forming galaxies between 3 and 1100 μm. A sequence of realistic galaxy spectra are constructed from a family of dust emission curves assuming a power law distribution of dust mass over a wide range of interstellar radiation fields. For each interstellar radiation field heating intensity we combine emissi...

It is known that vortex rings formed by large stroke ratios ~in a piston/cylinder arrangement! pinch off from their generating jets at a fairly constant universal time scale. In this paper we show that the hypothesis that at the pinch off the translational velocity of the ring equals the jet flow velocity near the ring is equivalent to the recently proposed idea based on a variational principle...

markowitz, in his portfolio selection theory, stated that investors select their portfolios according to two criteria of risk and return. accordingly, he presented his mathematical model. one of the criticisms of this model is that while investors, practically, consider different criteria in forming their portfolios, it only considers the return mean and return standard deviation. liquidity is ...

We compare the relations among various integrated characteristics of ?25 000 low-redshift ( z ? 1.0) compact star-forming galaxies (CSFGs) from Data Release 16 (DR16) Sloan Digital Sky Survey and high-redshift ? 1.5) (SFGs) with respect to oxygen abundances, stellar masses M ? , far-UV absolute magnitudes FUV star-formation rates SFR specific sSFR, Lyman-continuum photon production efficiencies...

In many multichannel high speed data acquisition applications, such as radar, satellite (beam-forming), MIMO, or high-energy experiments, it is critical to have phasecoherent channels for accurate data acquisition whether for demodulation, antenna calibration, channel sounding, or event capture. Large-scale experiments may require the use of tens or hundreds of synchronized channels, and very p...

We constructed new global potential energy surface for O + O2 → O3 reaction. It is based on high level electronic structure theory calculations and employs fitting by permutationally invariant polynomial functions. This method of surface construction takes full advantage of permutation symmetry of three O nuclei and allows reducing dramatically the number of ab initio data points needed for acc...

I will review recent progress in the modeling of the stellar spectral energy distributions of star-forming galaxies. I will cover the full relevant wavelength range from the near-infrared to the extreme ultraviolet, with an emphasis on the ultraviolet longand shortward of the Lyman break where most of the stellar luminosity is emitted. Uncertainties in stellar atmosphere and evolution models wi...
