There is a growing interest in using electroencephalography (EEG) and source modeling to investigate functional interactions among cortical processes, particularly when dealing with pediatric ...populations. This paper introduces two pipelines that have been recently used to conduct EEG FC analysis in the cortical source space. The analytic streams of these pipelines can be summarized into the following steps: 1) cortical source reconstruction of high-density EEG data using realistic magnetic resonance imaging (MRI) models created with age-appropriate MRI templates; 2) segmentation of reconstructed source activities into brain regions of interest; and 3) estimation of FC in age-related frequency bands using robust EEG FC measures, such as weighted phase lag index and orthogonalized power envelope correlation. In this paper we demonstrate the two pipelines with resting-state EEG data collected from children at 12 and 36 months of age. We also discuss the advantages and limitations of the methods/techniques integrated into the pipelines. Given there is a need in the research community for open-access analytic toolkits that can be used for pediatric EEG data, programs and codes used for the current analysis are made available to the public.

This White Paper presents the science case of an Electron-Ion Collider (EIC), focused on the structure and interactions of gluon-dominated matter, with the intent to articulate it to the broader ...nuclear science community. It was commissioned by the managements of Brookhaven National Laboratory (BNL) and Thomas Jefferson National Accelerator Facility (JLab) with the objective of presenting a summary of scientific opportunities and goals of the EIC as a follow-up to the 2007 NSAC Long Range plan. This document is a culmination of a community-wide effort in nuclear science following a series of workshops on EIC physics over the past decades and, in particular, the focused ten-week program on “Gluons and quark sea at high energies” at the Institute for Nuclear Theory in Fall 2010. It contains a brief description of a few golden physics measurements along with accelerator and detector concepts required to achieve them. It has been benefited profoundly from inputs by the users’ communities of BNL and JLab. This White Paper offers the promise to propel the QCD science program in the US, established with the CEBAF accelerator at JLab and the RHIC collider at BNL, to the next QCD frontier.
Electrical cables provide essential functions, such as delivery of power or instrumentation signals for monitoring systems. Most cables installed in industrial applications are constructed with ...organic polymer insulations that can become brittle, crack, or degrade over time from exposure to harsh environmental conditions, such as elevated temperatures, moisture, vibration, mechanical shock, and radiation. This paper describes an overall strategy for assessing the health and managing the aging of cables during the operating life of an industrial facility. This strategy involves performing condition assessments and monitoring of electrical cables using both in situ and laboratory testing techniques. It includes in situ testing to identify anomalies in the circuits, such as degraded terminations, splices, connections, and degraded sections of cable insulation, as well as as-found evaluations to determine the current condition of installed cables. These cable condition evaluations provide important information about the current state of the cable circuits. Moreover, the test results can be used to trend/monitor age-related degradation and estimate the remaining useful life of installed cables.
We apply the MC@NLO formalism to the production of heavy-quark pairs in pointlike photon–hadron collisions. By combining this result with its analogue relevant to hadron–hadron collisions, we obtain ...NLO predictions matched to parton showers for the photoproduction of QQ¯ pairs. We compare MC@NLO results to the measurements of c- and b-flavoured hadron observables performed by the H1 and ZEUS Collaborations at HERA.

Abstract
Across recent decades, profound changes in the practice of medicine have been accompanied by parallel developments in the daily mental efforts of medical professionals. Using visual ...metaphors and hand-drawn illustrations, the author explores the evolution of one physician’s brain over the past 25 years. At the completion of training, the patient-practitioner relationship, medical knowledge, and care decisions dominated clinician thought, time, and effort. During the 1990’s, the growing constraints of third-party payers and government regulations presented new challenges to delivering relationship-based care. Over the past decade, the electronic health record (EHR) has added further cognitive complexity, disrupted human relationships, and contributed significantly to the current epidemic of clinician burnout. Solutions to these challenges include rethinking education, documentation, professional standards, institutional barriers, and regulatory mandates. It is important to pursue all solutions with the underlying premise of protecting healing relationships as the foundation of clinical care.
Most Americans have little knowledge about why we elect the president through the Electoral College. This complex system that requires understanding the impact of 51 different elections on the ...outcome of the presidential election leads many Americans to desire the simple effectiveness of the popular vote method. Previous scholarship highlights a majority of Americans wanting to replace our current system with the popular vote. Political science research lacks a clear understanding of the impact of partisan self-interest on views of changing the presidential election method. In this paper we look at public opinion surveys over the last 45 years and find there was no clear partisan difference in views of changing the system before the electoral inversion of 2000. We argue that partisan self-interest was activated because of this electoral inversion. The inversion of 2016 led to a hardening of opinions on replacing the Electoral College with the popular vote.
