In multiple-choice tests, guessing is a source of test error which can be suppressed if its expected score is made negative by either penalizing wrong answers or rewarding expressions of partial knowledge. Starting from the most general formulation o

With a pedagogical aim suited for the upper-division undergraduate, we apply the old quantum theory (pre-Schrödinger) to the study of many-electron atomic species. We eschew the typical picture with circular atomic Bohr orbits of non-zero angular mo

The rising trend of coauthored academic works obscures the credit assignment that is the basis for decisions of funding and career advancements. In this paper, a simple model based on the assumption of an unvarying "author ability" is introduced. Wit

A dramatic improvement is reported in the stability of colloidal particles when stabilizing surface grafts are systematically shortened from small polymers to single monomers. The colloidal dispersions consist of fluorinated latex particles, exhibiti

The analysis of the angle dependence of the elastic scattering of radiation from a sample is an efficient and non-invasive technique that is used in fundamental science, in medicine and in technical quality control in industry. Precise information on

We analyze the w -index introduced by Wohlin (2009) theoretically. We formalize its definition mathematically and at the same time introduce a slightly more intuitive variation which also satisfies Woeginger's definition of a scientific impact index.

This study explores the thermodynamic and vibrational properties of water in the three-dimensional environment of solvated ions and small molecules using molecular simulations. The spectrum of intermolecular vibrations in liquid solvents provides det

Based on the dressed-ion theory and a simple physical argument regarding the conductivity of the solution, we derive a relation between the ionic strength and dielectric constant of an electrolyte solution. At its simplest, this model gives the diele

A computational method of predicting the effects of the metastability of drug solutions is sought. A simple extension of our in silicio approach to thermodynamic drug solubility is tested on the drug bicalutamide for which we performed vapor pressure

We introduce a simple improvement on the method to calculate equilibrium entropy differences between classical energy levels proposed by Davis [S. Davis, Phys. Rev. E 84, 050101 (2011)]. We demonstrate that the modification is superior to the origina
