Article Synopsis
  • Measuring deeply virtual Compton scattering (DVCS) on the neutron is essential for understanding the nucleon's structure through generalized parton distributions (GPDs).
  • Neutron targets help complement data obtained from polarized protons, particularly in determining the poorly understood GPD E, which is crucial for analyzing quark contributions to nucleon spin.
  • The experiment utilized a longitudinally polarized electron beam at Jefferson Lab and the CLAS12 detector to measure DVCS on the neutron for the first time, providing new insights into quark-flavor separation of relevant Compton form factors.

Dostoyevsky's novels raise profound ethical, moral, philosophical and theological issues and, as a result, both he and his novels serve as fertile subjects of scholarly inquiry across a variety of academic disciplines. In particular, major characters in "The Brothers Karamazov" lend themselves to classical psychodynamic formulations, such as the influence of adverse childhood experiences on adult social and occupational outcomes, which in the case of Dmitry, the eldest son of Fyodor Pavlovich Karamazov, are considered in exquisitely fine detail. Prosecutor and defense attorney provide differing interpretations of how early traumas, largely due to paternal neglect and abuse, affected Dmitry's adult outcome in the climactic trial over his alleged patricide.

Adiabatic light guide with S-shaped strips.

Rev Sci Instrum

October 2024

Department of Physics, James Madison University, Harrisonburg, Virginia 22807, USA.

A light guide is an essential part of many scintillator counters and light collection systems. Our main interest is a light guide for a thin, wide scintillator that has high light transmission while converting the area of the light source to the shape of a photo-detector. We propose a variation of the light guide that avoids a 90° twist of the strips, reduces the length of the light pipe, and reduces the complexity of production.

The fading affect bias (FAB) occurs in autobiographical memory when unpleasant emotions fade faster than pleasant emotions and the phenomenon appears to be a form of emotion regulation. As emotion regulation is positively related to problem solving, the current study examined FAB in the context of problem solving. In-person and online studies asked participants to provide basic demographics, describe their problem-solving abilities, and rate various healthy and unhealthy variables, including emotional intelligence and positive problem-solving attitudes.

Department of Organismal and Environmental Biology, Avenue of the Arts, Christopher Newport University, Newport News, VA 23606, USA.

Many plant species are known to take up metals from the soil and accumulate them to potentially toxic levels. This may provide tolerance to soils with high metal content or a defensive mechanism against herbivores and pathogens. Accumulators, plants that uptake and store elevated concentrations of metals, can be used in phytoremediation as a means to remove metals from contaminated soils.

The electromagnetic form factors of the proton and neutron encode information on the spatial structure of their charge and magnetization distributions. While measurements of the proton are relatively straightforward, the lack of a free neutron target makes measurements of the neutron's electromagnetic structure more challenging and more sensitive to experimental or model-dependent uncertainties. Various experiments have attempted to extract the neutron form factors from scattering from the neutron in deuterium, with different techniques providing different, and sometimes large, systematic uncertainties.

Listening to life: Sonification for enhancing discovery in biological research.

Biotechnol Bioeng

October 2024

Department of Chemical Engineering, School of Engineering and Applied Sciences, University of Virginia, Charlottesville, Virginia, USA.

Sonification, or the practice of generating sound from data, is a promising alternative or complement to data visualization for exploring research questions in the life sciences. Expressing or communicating data in the form of sound rather than graphs, tables, or renderings can provide a secondary information source for multitasking or remote monitoring purposes or make data accessible when visualizations cannot be used. While popular in astronomy, neuroscience, and geophysics as a technique for data exploration and communication, its potential in the biological and biotechnological sciences has not been fully explored.
