Prospects for beyond the Standard Model physics searches at the Deep Underground Neutrino Experiment: DUNE Collaboration

The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision detectors, and by the massive far detector system located deep underground. This configuration sets up DUNE as a machine for discovery, as it enables opportunities not only to perform precision neutrino measurements that may uncover deviations from the present three-flavor mixing paradigm, but also to discover new particles and unveil new interactions and symmetries beyond those predicted in the Standard Model (SM). Of the many potential beyond the Standard Model (BSM) topics DUNE will probe, this paper presents a selection of studies quantifying DUNE's sensitivities to sterile neutrino mixing, heavy neutral leptons, non-standard interactions, CPT symmetry violation, Lorentz invariance violation, neutrino trident production, dark matter from both beam induced and cosmogenic sources, baryon number violation, and other new physics topics that complement those at high-energy colliders and significantly extend the present reach.

Measurement of the Positive Muon Anomalous Magnetic Moment to 0.46 ppm

We present the first results of the Fermilab National Accelerator Laboratory (FNAL) Muon g-2 Experiment for the positive muon magnetic anomaly a_{μ}≡(g_{μ}-2)/2. The anomaly is determined from the precision measurements of two angular frequencies. Intensity variation of high-energy positrons from muon decays directly encodes the difference frequency ω_{a} between the spin-precession and cyclotron frequencies for polarized muons in a magnetic storage ring. The storage ring magnetic field is measured using nuclear magnetic resonance probes calibrated in terms of the equivalent proton spin precession frequency ω[over ˜]_{p}^{'} in a spherical water sample at 34.7 °C. The ratio ω_{a}/ω[over ˜]_{p}^{'}, together with known fundamental constants, determines a_{μ}(FNAL)=116 592 040(54)×10^{-11} (0.46 ppm). The result is 3.3 standard deviations greater than the standard model prediction and is in excellent agreement with the previous Brookhaven National Laboratory (BNL) E821 measurement. After combination with previous measurements of both μ^{+} and μ^{-}, the new experimental average of a_{μ}(Exp)=116 592 061(41)×10^{-11} (0.35 ppm) increases the tension between experiment and theory to 4.2 standard deviations.

Recognition and Treatment of Psychiatric Emergencies for Health Care Providers in the Emergency Department: Panic Attack, Panic Disorder, and Adverse Drug Reactions

Mental health disorders are common in the United States and may cause significant disturbances in all aspects of a person's life. Individuals with mental health disorders often present to emergency departments for health care. Recognizing and managing common psychiatric emergencies may be challenging for non-mental health providers. The Diagnostic Statistical Manual-5 diagnostic criteria will be discussed and reviewed for panic attack and panic disorder. Both pharmacologic and nonpharmacologic treatment strategies will also be addressed. Adverse drug reactions associated with antipsychotics and selective serotonin reuptake inhibitors are another common psychiatric emergency that will be examined, offering potential management strategies. The objective of this clinical manuscript is to educate emergency health care providers about specific psychiatric emergencies, including panic attack, panic disorder, and adverse drug reactions associated with mental health treatment medications.

The Emergence and Spread of Practice-Based Medical Education Research Networks

Educational research networks leverage shared goals and common infrastructure to overcome traditional barriers to medical education research, including small sample sizes, lack of generalizability, need for expertise in statistical analysis, and limitations on data sharing. The diversity of extant network models today is exciting and provides a set of common options and challenges that newly emerging networks can expect. These include decisions about network focus, organization of data, sampling strategies, funding, and governance. Common challenges include managing authorship, human subjects protection rules, data use agreements, and statistical disclosure control. Medical education research networks both advance the field and develop the researchers who participate in them. The authors repeat the call that they and others have made for the development of networks to promulgate best practices and coordinate multinetwork (multinational, multispecialty, and cross-curriculum) studies.

Narrative Performance Level Assignments at Initial Entrustment and Graduation: Integrating EPAs and Milestones to Improve Learner Assessment

PURPOSE

To determine which narrative performance level for each general pediatrics entrustable professional activity (EPA) reflects the minimum level clinical competency committees (CCCs) felt should be associated with graduation as well as initial entrustment and compare expected narrative performance levels (ENPLs) for each EPA with actual narrative performance levels (ANPLs) assigned to residents at initial entrustment.

METHOD

A series of 5 narratives, corresponding to the 5 milestone performance levels, were developed for each of the 17 general pediatrics EPAs. In academic year (AY) 2015-2016, the CCCs at 22 Association of Pediatric Program Directors Longitudinal Educational Assessment Research Network member sites reported ENPLs for initial entrustment and at time of graduation. From AYs 2015-2016 to 2017-2018, programs reported ANPLs for initial entrustment decisions. ENPLs and ANPLs were compared using a logistic mixed effects model.

RESULTS

ENPLs for graduation and entrustment were most often level 3 (competent) followed by level 4 (proficient). For 8 EPAs, the ENPLs for graduation and entrustment were the same. For the remaining 9, some programs would entrust residents before graduation or graduate them before entrusting them. There were 4,266 supervision level reports for initial entrustment for which an ANPL was provided. ANPLs that were lower than the ENPLs were significantly more likely to be assigned to the medical home-well child (OR = 0.39; 95% CI: 0.26-0.57), transition to adult care (OR = 0.43; 95% CI: 0.19-0.95), behavioral or mental health (OR = 0.36; 95% CI: 0.18-0.71), make referrals (OR = 0.31; 95% CI: 0.17-0.55), lead a team (OR = 0.34; 95% CI: 0.22-0.52), and handovers (OR = 0.18; 95% CI: 0.09-0.36) EPAs.

CONCLUSIONS

CCCs reported lower ENPLs for graduation than for entrustment for 5 EPAs, possibly indicating curricular gaps that milestones and EPAs could help identify.

High-Statistics Measurement of Neutrino Quasielasticlike Scattering at 6 GeV on a Hydrocarbon Target

We measure neutrino charged-current quasielasticlike scattering on hydrocarbon at high statistics using the wideband Neutrinos at the Main Injector beam with neutrino energy peaked at 6 GeV. The double-differential cross section is reported in terms of muon longitudinal (p_{∥}) and transverse (p_{⊥}) momentum. Cross section contours versus lepton momentum components are approximately described by a conventional generator-based simulation, however, discrepancies are observed for transverse momenta above 0.5  GeV/c for longitudinal momentum ranges 3-5 and 9-20  GeV/c. The single differential cross section versus momentum transfer squared (dσ/dQ_{QE}^{2}) is measured over a four-decade range of Q^{2} that extends to 10  GeV^{2}. The cross section turnover and falloff in the Q^{2} range 0.3-10  GeV^{2} is not fully reproduced by generator predictions that rely on dipole form factors. Our measurement probes the axial-vector content of the hadronic current and complements the electromagnetic form factor data obtained using electron-nucleon elastic scattering. These results help oscillation experiments because they probe the importance of various correlations and final-state interaction effects within the nucleus, which have different effects on the visible energy in detectors.

A Reflective Journey of Caring : A Case Study Between A Patient with Schizophrenia and the Interdisciplinary Team

This case study focuses on caring for a patient living with schizophrenia who has been isolated from the community caused by long-term hospitalization in Japan. Using the philosophical perspective of caring, which focuses on nurturing the wholeness and well-being of persons in caring relationship, the case study illuminates the caring, empathy, and courage among the interdisciplinary team. The purpose of this case study is to discuss the interdisciplinary caring process for patients living with schizophrenia using Carper's ways of knowing. Personal knowing is presented through the lens of patients and families and the stigma associated with mental illness. The expression of respect and caring for the patient and their families led by the interdisciplinary team aided in destigmatization of mental illness. Empirical and ethical knowing is demonstrated through the mental health care team's delivery of high quality and clinical excellence with competence, compassion and caring. Aesthetic knowing was offered by the interdisciplinary team focused on the patient's underlying hopes, dreams and aspirations. Through the support of the interdisciplinary team, patients are able to move toward their goals,hopes and dreams, externalizing tasks, as they grow together through mutual caring. J. Med.

Milestone Ratings and Supervisory Role Categorizations Swim Together, but Is the Water Muddy?

OBJECTIVE

This single-specialty, multi-institutional study aimed to determine 1) the association between milestone ratings for individual competencies and average milestone ratings (AMRs) and 2) the association between AMRs and recommended supervisory role categorizations made by individual clinical competency committee (CCC) members.

METHODS

During the 2015-16 academic year, CCC members at 14 pediatric residencies reported milestone ratings for 21 competencies and recommended supervisory role categories (may not supervise, may supervise in some settings, may supervise in all settings) for residents they reviewed. An exploratory factor analysis of competencies was conducted. The associations among individual competencies, the AMR, and supervisory role categorizations were determined by computing bivariate correlations. The relationship between AMRs and recommended supervisory role categorizations was examined using an ordinal mixed logistic regression model.

RESULTS

Of the 155 CCC members, 68 completed both milestone assignments and supervision categorizations for 451 residents. Factor analysis of individual competencies controlling for clustering of residents in raters and sites resulted in a single-factor solution (cumulative variance: 0.75). All individual competencies had large positive correlations with the AMR (correlation coefficient: 0.84-0.93), except for two professionalism competencies (Prof1: 0.63 and Prof4: 0.65). When combined across training year and time points, the AMR and supervisory role categorization had a moderately positive correlation (0.56).

CONCLUSIONS

This exploratory study identified a modest correlation between average milestone ratings and supervisory role categorization. Convergence of competencies on a single factor deserves further exploration, with possible rater effects warranting attention.

Key Factors in Clinical Competency Committee Members' Decisions Regarding Residents' Readiness to Serve as Supervisors: A National Study

PURPOSE

Entrustment has become a popular assessment framework in recent years. Most research in this area has focused on how frontline assessors determine when a learner can be entrusted. However, less work has focused on how these entrustment decisions are made. The authors sought to understand the key factors that pediatric residency program clinical competency committee (CCC) members consider when recommending residents to a supervisory role.

METHOD

CCC members at 14 pediatric residency programs recommended residents to one of five progressive supervisory roles (from not serving as a supervisory resident to serving as a supervisory resident in all settings). They then responded to a free-text prompt, describing the key factors that led them to that decision. The authors analyzed these responses, by role recommendation, using a thematic analysis.

RESULTS

Of the 155 CCC members at the participating programs, 84 completed 769 supervisory role recommendations during the 2015-2016 academic year. Four themes emerged from the thematic analysis: (1) Determining supervisory ability follows from demonstrated trustworthiness; (2) demonstrated performance matters, but so does experience; (3) ability to lead a team is considered; and (4) contextual considerations external to the resident are at play.

CONCLUSIONS

CCC members considered resident and environmental factors in their summative entrustment decision making. The interplay between these factors should be considered as CCC processes are optimized and studied further.

A preliminary trial of an online dissonance-based eating disorder intervention

OBJECTIVE

We conducted a controlled randomized preliminary trial of an expanded online version of the Body Project (n = 46) compared to an assessment-only control condition (n = 36) via a longitudinal design (baseline, postintervention, 2-month follow-up) in a community sample of women (N = 82) with clinical (n = 53) and subclinical (n = 29) eating disorder symptoms.

METHOD

The traditional content of the Body Project was modified to include verbal, written, and behavioral exercises designed to dissuade objectification and maladaptive social comparison and adapted to an online format. Body dissatisfaction, self-esteem, self-objectification, thin-ideal internalization, maladaptive social comparison, trait anxiety, positive affect, negative affect, and eating disorder symptomatology were evaluated in the control and the online expanded Body Project condition at baseline, postintervention, and 2-month follow-up.

RESULTS

A 2 (condition: online expanded Body Project, control) × 3 (time: baseline, postintervention, 2-month follow-up) mixed factorial multivariate analysis of variance (MANOVA) was conducted to examine statistically significant group differences. As predicted, results indicated a statistically significant condition × time interaction.

CONCLUSIONS

Participants in the expanded online Body Project condition showed significant reductions in eating disorder symptoms and several associated psychological risk correlates from baseline to postintervention and follow-up; contrary to predictions, eating disorder symptoms and risk correlates were not significantly lower in the online expanded Body Project condition compared to the waitlist control condition at postintervention or 2-month follow-up.

ALP production through non-linear Compton scattering in intense fields

We derive production yields for massive pseudo-scalar and scalar axion-like-particles (ALPs), through non-linear Compton scattering of an electron in the background of low- and high-intensity electromagnetic fields. In particular, we focus on electromagnetic fields from Gaussian plane wave laser pulses. A detailed study of the angular distributions and effects of the scalar and pseudo-scalar masses is presented. It is shown that ultra-relativistic seed electrons can be used to produce scalars and pseudo-scalars with masses up to the order of the electron mass. We briefly discuss future applications of this work towards lab-based searches for light beyond-the-Standard-Model particles.

Factors Associated With Refusal of Intramuscular Vitamin K in Normal Newborns

BACKGROUND AND OBJECTIVE

Refusal of intramuscular (IM) vitamin K administration by parents is an emerging problem. Our objective was to assess the frequency of and factors associated with refusal of IM vitamin K administration in well newborns in the United States.

METHODS

We determined the number of newborns admitted to well newborn units whose parents refused IM vitamin K administration in the Better Outcomes through Research for Newborns network and, in a nested patient-control study, identified factors associated with refusal of IM vitamin K administration by using a multiple logistic regression model.

RESULTS

Of 102 878 newborns from 35 Better Outcomes through Research for Newborns sites, parents of 638 (0.6%) refused IM vitamin K administration. Frequency of refusal at individual sites varied from 0% to 2.3%. Exclusive breastfeeding (adjusted odds ratio [aOR] = 3.4; 95% confidence interval [CI]: 2.1-5.5), non-Hispanic white race and/or ethnicity (aOR = 1.7; 95% CI: 1.2-2.4), female sex (aOR = 1.6; 95% CI: 1.2-2.3), gestational age (aOR = 1.2; 95% CI: 1.1-1.4), and mother's age (aOR = 1.05; 95% CI: 1.02-1.08) were significantly associated with refusal of IM vitamin K administration. Refusal of the administration of both ocular prophylaxis and hepatitis B vaccine was also strongly associated with refusal of IM vitamin K administration (aOR = 88.7; 95% CI: 50.4-151.9).

CONCLUSIONS

Refusal of IM vitamin K by parents of newborns is a significant problem. Interventions to minimize risks to these newborns are needed.
