Lisi, Marrone, and Montanino have recently proposed a test for quantum gravity induced decoherence effects in neutrino oscillations observed at Super-Kamiokande. We comment here that their equations have the same qualitative form as the energy conserving objective state vector reduction equations discussed by a number of authors. However, using the Planckian parameter value proposed to explain ...

A brief review is given of the continuous spontaneous localization (CSL ) model , in which a classical field interacts with quantized particles to cause dynamical wavefunction collapse. One of the model ’s predictions is that particles `̀ spontaneously’’ gain energy at a slow rate. When applied to the excitation of a nucleon in a Ge nucleus, it is shown how a limit on the relative collapse rates...

A fundamental postulate of quantum mechanics states that a measurement of a quantum system causes the collapse of the wave function. This is in contrast to the smooth, continuous, deterministic time evolution of the wave function in between measurements, governed by the Schrodinger equation. The latter is similar to classical physics; the former is unique to quantum mechanics. (Note that many ...

This paper studies gravitational collapse of a complex scalar field at the threshold for black hole formation, assuming that the collapse is spherically symmetric and continuously self-similar. A new solution of the coupled Einstein-scalar field equations is derived, after a small amount of numerical work with ordinary differential equations. The universal scaling and echoing behavior discovere...

Nowadays it is common to use the fragility curves in probabilistic methods to determine the collapse probability resulting from an earthquake. The uncertainties exist in intensity and frequency content of the earthquake records are considered as the most effective parameters in developing the fragility curves. The pulse-type records reported in the near-fault regions might lead to the major dam...

Dams are known to impact river channels and ecosystems, both during their lifetime and in their decommissioning. In this study, we applied a before-after-control-impact design associated with two small dam removals to investigate abiotic and biotic recovery trajectories from both the elimination of the press disturbance associated with the presence of dams and the introduction of a pulse distur...

Global Navigation Satellite Systems (GNSS) receivers are nowadays commonly used in monitoring applications, e.g., in estimating crustal and infrastructure displacements. This is basically due to the recent improvements in GNSS instruments and methodologies that allow high-precision positioning, 24 h availability and semiautomatic data processing. In this paper, GNSS-estimated displacements on a...

“New Physics" (NP) refers to physics beyond the “Standard Model," the paradigm that we have constructed to explain our current high energy physics data [1]. We know, however, that NP is required to explain certain global phenomena including the Baryon asymmetry of the Universe, without which we could not exist, or the “Dark Matter," found first by Zwicky studying rotation curves of galaxies [2]...

Now more and more ecologists concern about the impacts of dam construction on fish. However, studies of fishes downstream Gezhouba Dam were rarely reported except Chinese sturgeon (Acipenser sinensis Gray). In this study, catch investigations and five hydroacoustic detections were completed from 2015 to 2016 to understand the distribution, size, and categories of fishes and their relationship w...
