Ratio of Loss and Storage Moduli Determines Restitution Coefficient in Low-Velocity Viscoelastic Impacts [PDF]
, 2020 Impact tests are an important tool to analyze dynamic material properties of viscoelastic media in technology and biology. In this context, rigorous contact mechanical models of the collision problem are necessary to adequately interpret data from impact

Air Pressure and Coefficient of Restitution of a Ball [PDF]
International Scholastic Journal of Science, 2013 The relationship between the pressure of a ball and its coefficient of restitution was investigated, a rubber handball was inflated to eight varying air pressures and then dropped from a constant height. With measurements of its mass, circumference,

Pathogenic Germline PALB2 and RAD50 Variants in Patients With Relapsed Ewing Sarcoma
Pediatric Blood &Cancer, EarlyView.ABSTRACT Approximately 10% of patients with Ewing sarcoma (EwS) have pathogenic germline variants. Here, we report two cases: first, a novel germline pathogenic variant in partner and localizer of BRCA2 (PALB2) in a patient with a late EwS relapse. Its impact on homologous recombination is demonstrated, and breast cancer risk is discussed.

Stanisław Lisowski and the Restitution of Incunabula of Monastic Provenance under the Treaty of Riga (1921) [PDF]
Kwartalnik HistorycznyThe Treaty of Riga is considered one of the most important documents of the first half of the twentieth century for Eastern Europe. Few studies, however, address the question of the restitution of library and archive collections.

Coefficient of restitution for elastic disks
, 1998 We calculate the coefficient of restitution, $\epsilon$, starting from a microscopic model of elastic disks. The theory is shown to agree with the approach of Hertz in the quasistatic limit, but predicts inelastic collisions for finite relative ...
