Effects of Neutrino Oscillation on the Supernova Neutrino Spectrum [PDF]

, 2001
The effects of three-flavor neutrino oscillation on the supernova neutrino spectrum are studied. We calculate the expected event rate and energy spectra, and their time evolution at the Superkamiokande (SK) and the Sudbury Neutrino Observatory (SNO), by ...

Deep-Ocean Crusts as Telescopes: Using Live Radioisotopes to Probe Supernova Nucleosynthesis [PDF]

, 2004
Live 60Fe has recently been detected in a deep-ocean ferromanganese crust, isolated in layers dating from about 3 Myr ago. Since 60Fe has a mean life of 2.2 Myr, a near-Earth supernova is the only likely source for such a signal, and we explore here the ...

Physics with Supernovae [PDF]

, 2002
Core-collapse supernovae (SNe) are powerful neutrino sources and as such important targets for the growing array of neutrino observatories. We review the current status of SN theory and the expected characteristics of the neutrino signal. After recalling

Radiation Hardened Infrared Photodetectors Based on a Narrow Bandgap Conjugated Polymer Semiconductor

Advanced Electronic Materials, EarlyView.
A blackbody‐sensitive infrared photodetector comprised of an open‐shell conjugated polymer demonstrates high sensitivity without cooling and exceptional radiation hardness, surpassing inorganic compound semiconductor devices. This functionality, inherent to the polymer semiconductor, provides a new frontier for low‐cost, size, weight, and power space ...

Footprints of the Newly-Discovered Vela Supernova in Antarctic Ice Cores?

, 1999
The recently-discovered, nearby young supernova remnant in the southeast corner of the older Vela supernova remnant may have been seen in measurements of nitrate abundances in Antarctic ice cores.

Toward Reuse‐Ready PV: A Perspective on Recent Advances, Practices, and Future Challenges

Advanced Energy and Sustainability Research, EarlyView.
This perspective study sheds light on current research and future challenges toward higher PV reuse readiness in PV industry. It highlights qualification methods, PV repair strategies, and standardization efforts for PV reuse. A four‐step example of triage‐for‐reuse framework is discussed, as well as recent advances in PV repair strategies for reuse ...

Tycho Brahe's 1572 supernova as a standard type Ia explosion revealed from its light echo spectrum [PDF]

, 2008
Type Ia supernovae (SNe Ia) are thermonuclear explosions of white dwarf stars in close binary systems. They play an important role as cosmological distance indicators and have led to the discovery of the accelerated expansion of the Universe.

SNOC: A Monte-Carlo simulation package for high-z supernova observations [PDF]

, 2002
We present a Monte-Carlo package for simulation of high-redshift supernova data, SNOC. Optical and near-infrared photons from supernovae are ray-traced over cosmological distances from the simulated host galaxy to the observer at Earth.

Review of the anatomical basis for predicting plutonium alpha particle radiation induced osteogenic cancers

The Anatomical Record, EarlyView.
Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.
