Ultrahigh Energy Cosmic Rays: Old Physics or New Physics? [PDF]

, 2004
We consider the advantages of and the problems associated with hypotheses to explain the origin of ultrahigh energy cosmic rays (UHECR: E greater than 10 EeV) and the "trans-GZK" cosmic rays (TGZK: E greater than 100 EeV) both through "old physics ...

Fin whale song recordings by onshore seismometers open new horizons for cetacean coastal monitoring

Scientific Reports
Fin whales, the second largest animal on Earth, produce one of the most intense vocalisations in the animal kingdom. Monitoring these songs using ocean-deployed hydrophones plays an important role in the study of fin whale distribution and social ...

PHYSICS WITH COSMIC NEUTRINOS, PEV TO ZEV [PDF]

Neutrinos and Implications for Physics Beyond the Standard Model, 2003
Neutrinos offer a particularly promising eye on the extreme Universe. Neutrinos are not attenuated by intervening radiation fields such as the Cosmic Microwave Background, and so they are messengers from the very distant and very young phase of the universe. Also, neutrinos are not deflected by cosmic magnetic fields, and so they should point to their

Managing Spectral Intensity Variations With In‐Line Fiber‐Optic High‐Volume Noncontact Raman Probes: A Strategy Exploration

Journal of Raman Spectroscopy, EarlyView.
Robust quantification in noncontact Raman sensing requires dedicated correction of working distance dependent background effects, while laser power variations are readily stabilized using internal reference signals. Chemically relevant Raman intensity can be preserved for bulk composition measurements, under variable laser power and working distance ...

Exotic Physics With Ultrahigh Energy Cosmic Rays. [PDF]

, 2007
Presented at the XXXI International Conference of Theoretical Physics, “Matter to the Deepest”, Ustroń, Poland, September 5–11, 2007.Ultrahigh energy cosmic rays provide a unique ground for probing new physics. In this talk we review the possibility of

Probing the BSM physics with CMB precision cosmology: an application to supersymmetry

Journal of High Energy Physics, 2018
The cosmic history before the BBN is highly determined by the physics that operates beyond the Standard Model (BSM) of particle physics and it is poorly constrained observationally.

Discriminating Chemoresistant and Chemosensitive Tubo‐Ovarian High‐Grade Serous Carcinoma Cells With Raman Microscopy

Journal of Raman Spectroscopy, EarlyView.
Confocal Raman microscopy combined with multivariate analysis distinguishes cisplatin‐resistant and ‐sensitive tubo‐ovarian high‐grade serous carcinoma cell lines. ABSTRACT Chemoresistance is a major obstacle to effective cancer treatment, particularly in tubo‐ovarian high‐grade serous carcinoma (HGSC), the most lethal gynaecological malignancy ...

On the relationship of cosmic ray flux and precipitation [PDF]

, 2001
This paper evaluates whether there is empirical evidence to support the hypothesis that solar variability is linked to the Earth's climate through the modulation of atmospheric precipitation processes.

Identifying MESSENGER Magnetospheric Boundary Crossings Using a Random Forest Region Classifier

Journal of Geophysical Research: Machine Learning and Computation
We present a new list of bow shock and magnetopause crossings based on automated region classification for the MESSENGER (Mercury Surface, Space Environment, Geochemistry and Ranging) mission.
