An extended nonlinear recharge oscillator model shows skilful and explainable El Niño–Southern Oscillation forecasts at lead times up to 16–18 months, better than global climate models and comparable to the most skilful artificial intelligence forecasts. ...
Vector-like fermions are theoretically well-motivated BSM candidates [18, 98,99,100,101] to construct anomaly-free UV-complete theories. Due to the leptophilic nature of Z′, the considered framework is particularly suitable for describing a sub-GeV DM as the mass regime is kinematically more ...
In Nature three generations of quarks and leptons have been observed. Number of neutrino flavours is 2.984±0.008 [1]–[7], which is a statistical fit to SM using LEP data. This is a strong indication for exactly three generations of matter, which, however, is not imposed by SM itself....

What he probably doesn't know is that mother nature puts 24,000 times that amount of our main greenhouse gas -- water vapour -- into the atmosphere every day, and removes about the same amount every day. While this does not 'prove' that global warming is not man-made, it shows that...
It has been found that completely different physical impacts can be observed, depending on US parameters and particularly on the nature of plant matrices. These different mechanisms were summarized in a review published by Chemat et al [1]. As explained in this review, depending on their ...
(1994). They find that ripple-fired blasts show distinct frequency bands related to the repetitive nature of the source, which allows a discrimination from instantaneous blasts or earthquakes. Stump et al. (2002) show that mining blasts dis- play a repeated pattern in the frequency domain ...
. . . . . 20 1 Introduction Neutrino oscillation data clearly indicate that neutrinos have small but non-zero masses [1]. A simple theoretical paradigm for the origin of neutrino mass is the seesaw mechanism, which predicts the Majorana nature of neutrinos; for a review, see e.g. Ref. ...
The origin, nature and ordering of the neutrino masses remain open questions, but cosmology suggests that all neutrino masses must be below about 100 meV [7], making them by far the lightest (known) fermions in nature. There are hints of CP violation in the lepton sector [8] but so far...
