As regularly and as certainly, as century succeeds century, or progeny progenitors; we find it difficult to account for that secret principle which prompts us to expend so much labopr, learning, health, wealth, and irrevocable time, in the construction of literary edifices, which, however majestic or beautiful in themselves, have their foundations necessarily washed by an ever-moving tide that ...

An integrative review of three theories that explain why some individuals engage in persistent pursuit—coercive control theory, relational goal pursuit, and attachment theory— is presented. The meta-analytic evidence pointing to persistent pursuit as a gendered behavior is reviewed, and coercive control theory is used to explain gender differences. The strong conceptual and empirical overlap be...

1.1. Three surprises of high dimensions. This paper develops asymptotic methods to count faces of random high-dimensional polytopes; a seemingly dry and unpromising pursuit. Yet our conclusions have surprising implications in statistics, probability, information theory, and signal processing with potential impacts in practical subjects like medical imaging and digital communications. Before inv...

The compound LLPNP crystallizes in orthorhombic system, P21 21 21 space group with four molecules in the asymmetric unit. The crystal data for LLPNP is tabled. The lysine molecule (C1-C6/N1/N2/O1/O2) is protonated while the paranitrophenol molecule is deprotonated (C7-C12/N3/O3/O4/O5). The paranitrophenol moiety makes a dihedral angle of 85.87 (9)° with the lysine moiety which shows that they a...

We introduce and study a calculus for real-valued square matrices, called partial inversion, and an associated calculus for binary square matrices. The first, applied to systems of recursive linear equations, generates new sets of parameters for different types of statistical joint response models. The corresponding generating graphs are directed and acyclic. The second calculus, applied to mat...

A set of small nonpeptidic diaryl phosphonate inhibitors was prepared. The phosphonate derivatives were synthesized through Birum-Oleksyszyn reaction followed by reduction of the nitro-group which undergo to Boc-protected guanidine derivatives. After removing of Boc-group by TFAA/DCM afford the guanidine phosphonates.

A synthesis of functionalized fused pyrimidine derivatives from the respective ortho-nitroaromatic carboximes is described. Commercially available nitroarenes were transformed according to a known manner into the ortho-nitroaromatic carboximes. Selective catalytic reduction of the nitro group in these compounds followed by condensation of the amines formed with various orthoesters, resulted in ...

Timing is one of the most critical factors of software size estimation. We need to know quite a bit about the software project to make a meaningful size estimate. However, most of the software estimates should be performed at the beginning of the life cycle, when we do not yet know the problem we are going to solve. In the literature, there are few early size estimation methods. This study demo...

Interaction between nitrobenzene and silver cluster is investigated using the Density Functional Theory (DFT) at the B3PW91 level of theory. Adsorption causes a variation in the structural parameters. The charge transfer from silver cluster to nitrobenzene is identified from the plot of the molecular electrostatic potential (MEP) surface and natural population analysis (NPA). A marked enhanceme...
