supergravity/ particle dark matter modelsdark matter detection ratesPredictions of dark matter detection rates for terrestial detectors are given within the framework of supergravity grand unified models with R parity invariance. These models predict that the lightest neutralino,χ , should be a ...
Second graders' emerging particle models of matter in the context of learning through model‐based inquiry In this paper, we present a study of second graders' learning about the nature of matter in the context of content-rich, model-based inquiry instruction. T... A Samarapungavan,L Bryan,...

Hence, the material of an FR must face a broad range of temperatures when in operation; for example, around a variation of 300°C, this fact is an important matter for the springs and the dimples as those must not impose an excessive gripping force on the rod, allowing it some axial ...
BACKGROUND: Subclinical atherosclerosis has been associated with long-term exposure to particulate matter (PM), but the relevance of particle size and sources of exposure remains unclear. OBJECTIVES: We investigated the association of long-term exposure to PM10 (¤ 10 m), PM2.5 (¤ 2.5 m: tota...
These neutrino events will also shed light on forward hadron production and both perturbative and non-perturbative QCD, with strong implications for models of collider physics and astroparticle experiments. For new physics searches, the far-forward region is also promising, because the SM particles ...
Agricultural operations across the United States are encountering difficulties in complying with the current air pollution regulations for particulate matter (PM). The National Ambient Air Quality Standards (NAAQS) for PM in terms of PM2.5, are ambient air concentration limits set by EPA that should...
Constraints on fifth forces and ultralight dark matter from OSIRIS-REx target asteroid Bennu Asteroid tracking has been demonstrated as a promising and prominent probe of fifth forces arising in several well-motivated models beyond the Standard Model of particle physics. The authors use the state-of...
The role of particle shape in computational modelling of granular matter Article 10 August 2023 Open-source support toward validating and falsifying discrete mechanics models using synthetic granular materials—Part I: Experimental tests with particles manufactured by a 3D printer Article 23 July 201...
, the contact plane and contact point) are very sensitive to the geometric shape of the particle. Therefore, various particle models have been proposed for accurately describing the shape of the non-spherical particle, e.g., the multi-sphere model [44,45], super-ellipsoid model [46–49], ...
