Book excerpt: This book presents the first simultaneous detection of neutrons and positrons after a terrestrial gamma-ray flash (TGF), a highest-energy transient phenomenon on the earth, triggered by a lightning discharge, based on innovative ground-based observations made in the Hokuriku area of Japan. TGFs, known to be produced by lightning discharges since the 1990s, has been theoretically predicted to react with atmospheric nuclei via photonuclear reactions because they comprise high-energy photons of more than 10 MeV, but such photonuclear reactions by lightning discharges, which produce neutrons and unstable isotopes emitting positrons, were not observationally confirmed. The reactions and propagations of their products in the atmosphere are modeled with Monte Carlo simulations to quantitatively evaluate observations of TGFs, neutrons, and positrons at ground level. The successful comparison between observation and simulation is presented, and demonstrates that lightning discharges to trigger photonuclear reactions and to even produce isotopes in the atmosphere.

Available in PDF, EPUB and Kindle. Book excerpt: Outside of randomized experiments, association does not imply causation, and yet there is nothing defective about our knowledge that smoking causes lung cancer, a conclusion reached in the absence of randomized experimentation with humans. How is that possible? If observed associations do not identify causal effects in observational studies, how can a sequence of such associations become decisive? Two or more associations may each be susceptible to unmeasured biases, yet not susceptible to the same biases. An observational study has two evidence factors if it provides two comparisons susceptible to different biases that may be combined as if from independent studies of different data by different investigators, despite using the same data twice. If the two factors concur, then they may exhibit greater insensitivity to unmeasured biases than either factor exhibits on its own. Replication and Evidence Factors in Observational Studies includes four parts: A concise introduction to causal inference, making the book self-contained Practical examples of evidence factors from the health and social sciences with analyses in R The theory of evidence factors Study design with evidence factors A companion R package evident is available from CRAN.

Available in PDF, EPUB and Kindle. Book excerpt: Why psychology is in peril as a scientific discipline—and how to save it Psychological science has made extraordinary discoveries about the human mind, but can we trust everything its practitioners are telling us? In recent years, it has become increasingly apparent that a lot of research in psychology is based on weak evidence, questionable practices, and sometimes even fraud. The Seven Deadly Sins of Psychology diagnoses the ills besetting the discipline today and proposes sensible, practical solutions to ensure that it remains a legitimate and reliable science in the years ahead. In this unflinchingly candid manifesto, Chris Chambers shows how practitioners are vulnerable to powerful biases that undercut the scientific method, how they routinely torture data until it produces outcomes that can be published in prestigious journals, and how studies are much less reliable than advertised. Left unchecked, these and other problems threaten the very future of psychology as a science—but help is here.

Book excerpt: This book summarizes research of strongly nonlocal processes in dense weakly ionized atmospheric and laboratory plasmas beginning with the prediction of C. Wilson in 1925. Fundamentals of the nonlocal model of breakdown and discharges in dense gases formulated by Prof. Babich in the 1970s underlie experimental research and numerical simulations of discharges in dense gases in very strong electric fields. Earlier unknown phenomena and gas-discharge dependencies discovered by Prof. Babich and his colleagues have been the focus of international attention and interest.

This book was released on 2015-11-30 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the relevant consequences of recently discovered and interdisciplinary phenomena, triggered by local mechanical instabilities. In particular, it looks at emissions from nano-scale mechanical instabilities such as fracture, turbulence, buckling and cavitation, focussing on vibrations at the TeraHertz frequency and Piezonuclear reactions. Future applications for this work could include earthquake precursors, climate change, energy production and cellular biology. A series of fracture experiments on natural rocks demonstrates that the TeraHertz vibrations are able to induce fission reactions on medium weight elements accompanied by neutron emissions. The same phenomenon appears to have occurred in several different situations, particularly in the chemical evolution of the Earth and Solar System, through seismicity (rocky planets) and storms (gaseous planets). As the authors explore, these phenomena can also explain puzzles related to the history of our planet, like the ocean formation or the primordial carbon pollution, as well as scientific mysteries, like the so-called “cold nuclear fusion” or the correct radio-carbon dating of organic materials, such as the Turin Shroud. In biology, Piezonuclear reactions could explain the mechanism that governs the so-called "sodium-potassium pump" and more in general, the metabolic processes. Scientists engaged in seismology, geophysics, geochemistry, climatology, planetology, condensed matter physics and b iology, as well as those involved in theoretical and applied mechanics, will all appreciate the innovative work presented here in a holistic way.
