The Poker Face of Inelastic Dark Matter: Prospects at Upcoming Direct Detection Experiments
, 2010 The XENON100 and CRESST experiments will directly test the inelastic dark matter explanation for DAMA's 8.9? sigma anomaly. This article discusses how predictions for direct detection experiments depend on uncertainties in quenching factor measurements ...

Improving Formative Assessment Practice with Educational Information Technology [PDF]
Journal of Systemics, Cybernetics and Informatics, 2006 This paper describes a web-based assessment design tool, the ADDS, that provides teachers both a structure and the resources required to develop and use quality assessments. The tool is applicable across subject domains.

The X-Ray Evolution of the Symbiotic Star V407 Cyg During its 2010 Outburst
Open Astronomy, 2012 We present a summary of Swift and Suzaku X-ray observations of the 2010 nova outburst of the symbiotic star, V407 Cyg. the Suzaku spectrum obtained on day 30 indicates the presence of the supersoft component from the white dwarf surface, as well as ...

Journal of Educational Measurement, Volume 63, Issue 1, Spring 2026.Abstract Process information collected from educational games can illuminate how students approach interactive tasks, complementing assessment outcomes routinely examined in evaluation studies. However, the two sources of information are historically analyzed and interpreted separately, and diagnostic process information is often underused.

The Complex X-Ray Obscuration Environment in the Radio-loud Type 2 Quasar 3C 223
The Astrophysical Journal, 2023 3C 223 is a radio-loud, Type 2 quasar at z = 0.1365 with an intriguing X-ray Multi-mirror Mission (XMM)-Newton spectrum that implicated it as a rare, Compton-thick ( N _H ≳ 1.25 × 10 ^24 cm ^−2 ) active galactic nucleus (AGN). We obtained contemporaneous

Are direct search experiments sensitive to all spin-independent WIMP candidates?
, 2005 The common analysis of direct searches for spin-independent Weakly Interacting Massive Particles (WIMPs) assumes that a spin-independent WIMP couples with the same strength with both nucleons, \textit{i.e.} that the spin-independent interaction is also ...

Radiation Transport Through the Martian Atmosphere as a Function of the Zenith Angle
Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.Abstract The topographic influence of the radiation environment on the Martian surface radiation is crucial for future human exploration. Topographic maps help assess radiation flux variations, aiding in hazard evaluation. Creating a global radiation map requires accounting for seasonally varying atmospheric density, heliospheric modulation, and ...

The Sun as a sub-GeV Dark Matter Accelerator [PDF]
, 2018 Sub-GeV halo dark matter that enters the Sun can potentially scatter off hot solar nuclei and be ejected much faster than its incoming velocity. We derive an expression for the rate and velocity distribution of these reflected particles taking into ...

Global Occurrence of Kelvin‐Helmholtz Vortices at Mars
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract We analyzed six Kelvin‐Helmholtz (K‐H) vortex events from Mars Atmosphere and Volatile EvolutioN (MAVEN) measurements. We found that fully developed vortices can occur at Mars' equatorial flanks and in the southern hemisphere, while they were previously observed only in the northern hemisphere.
