A SOLUTION OF SUN'S $520 CHALLENGE CONCERNING $\frac{520}{\pi}$ [PDF]
We prove a Ramanujan-type formula for 520/π conjectured by Zhi-Wei Sun. Our proof begins with a hypergeometric representation of the relevant double series, which relies on a recent generating function for Legendre polynomials by Wan and Zudilin. After showing that appropriate modular parameters can be introduced, we then apply standard techniques ...

Big boys don't cry: Depression and men [PDF]
Men are a numerical minority group receiving a diagnosis of, and treatment for, depression. However, community surveys of men and of their mental health issues (e.g. suicide and alcoholism) have led some to suggest that many more men have depression than

Reliability modeling of a 1-out-of-2 system: Research with diverse Off-the-shelf SQL database servers [PDF]
Fault tolerance via design diversity is often the only viable way of achieving sufficient dependability levels when using off-the-shelf components. We have reported previously on studies with bug reports of four open-source and commercial off-the-shelf ...

Full-Field, Carrier-Less, Polarization-Diversity, Direct Detection Receiver based on Phase Retrieval [PDF]
We realize dual-polarization full-field recovery using intensity only measurements and phase retrieval techniques based on dispersive elements. 30-Gbaud QPSK waveforms are transmitted over 520-km standard single-mode fiber and equalized from the receiver

Desires, norms and constraints [PDF]
This paper deals with modeling mental states of a rational agent, in particular states based on agent’s desires. It shows that the world the agent belongs to forces it to restrict its desires. More precisely, desires of a rational agent are restricted by

Ethical issues in implementation research: a discussion of the problems in achieving informed consent [PDF]
Background: Improved quality of care is a policy objective of health care systems around the world. Implementation research is the scientific study of methods to promote the systematic uptake of clinical research findings into routine clinical practice ...

Theoretical Description of the Role of Halides, Silver, and Surfactants on the Structure of Gold Nanorods [PDF]
Density functional theory simulations including dispersion provide an atomistic description of the role of different compounds in the synthesis of gold-nanorods.

The rich cluster Abell 520 (z=0.201) exhibits truly extreme and puzzling multi-wavelength characteristics. It may best be described as a "cosmic train wreck." It is a major merger showing abundant evidence for ram pressure stripping, with a clear offset ...

Magnetism in nanometer-thick magnetite [PDF]
The oldest known magnetic material, magnetite, is of current interest for use in spintronics as a thin film. An open question is how thin can magnetite films be and still retain the robust ferrimagnetism required for many applications.

Influence of secondary phases during annealing on re-crystallization of CuInSe2 electrodeposited films [PDF]
Electrodeposited CuInSe2 thin films are of potential importance, as light absorber material, in the next generation of photovoltaic cells as long as we can optimize their annealing process to obtain dense and highly crystalline films.
