Abstract
Objective. The continuous delivery of oxygen is critical to sustain brain function, and therefore, measuring brain oxygen consumption can provide vital physiological insight. In this work, we examine the impact of calibration and cerebral blood flow (CBF) measurements on the computation of the relative changes in the cerebral metabolic rate of oxygen consumption (rCMRO2) from hemoglobin-sensitive intrinsic optical imaging data. Using these data, we calculate rCMRO2, and calibrate the model using an isometabolic stimulus.Approach. We used awake head-fixed rodents to obtain hemoglobin-sensitive optical imaging data to test different calibrated and uncalibrated rCMRO2models. Hypercapnia was used for calibration and whisker stimulation was used to test the impact of calibration.Main results. We found that typical uncalibrated models can provide reasonable estimates of rCMRO2with differences as small as 7%-9% compared to their calibrated models. However, calibrated models showed lower variability and less dependence on baseline hemoglobin concentrations. Lastly, we found that supplying the model with measurements of CBF significantly reduced error and variability in rCMRO2change calculations.Significance. The effect of calibration on rCMRO2calculations remains understudied, and we systematically evaluated different rCMRO2calculation scenarios that consider including different measurement combinations. This study provides a quantitative comparison of these scenarios to evaluate trade-offs that can be vital to the design of blood oxygenation sensitive imaging experiments for rCMRO2calculation.

Abstract
INTRODUCTION Breast cancer is a common malignant tumor among women, and the effectiveness of diagnosing its metastasis and recurrence has been demonstrated using diffusion-weighted whole-body imaging with background body signal suppression (DWIBS). However, DWIBS causes distress to patients due to the unique circumstances of magnetic resonance imaging (MRI). This study aimed to investigate the various distress factors caused by DWIBS among women with breast cancer and assess the effectiveness of a new MRI system designed with an environment incorporating relaxing technology. METHODS From May to September 2022, we conducted a questionnaire survey regarding DWIBS-related distress among women with breast cancer. The questionnaire was administered to participants who underwent DWIBS on a conventional MRI system (19 women) and on a new system (20 women) equipped with relaxing technology equipped features, including projection images, illumination, and sound. Participants rated the degree of various stress factors on a face-scale rating scale (0-10). The scores of both systems were compared using the Mann-Whitney U test. RESULTS In the conventional system, women experienced distress due to MRI-specific situations, such as immobility in a confined space, noise, feeling trapped, and concerns about not moving. These results did not show a specific tendency among women with breast cancer undergoing DWIBS. For almost all distress parameters, the new system had significantly lower distress scores than the conventional system (p > 0.05). CONCLUSIONS A comfortable environment using new and relaxing technology is effective in alleviating patient's anxiety by approaching the human senses. IMPLICATIONS FOR PRACTICE Reducing distress caused by DWIBS among women with breast cancer could provide a comfortable examination environment, potentially assisting them during longer treatment periods.

Abstract
OBJECTIVE Research is needed to examine discrimination-related stressors and their social and psychological shaping of mental health and sleep outcomes of Latinx youth. The background, design, and methodology of a longitudinal study of Mexican families in Indiana and the initial findings of associations between discrimination-related stressors and youth mental health and sleep outcomes are presented. METHOD Initiating wave 1 of a 3-wave (yearly) longitudinal study, investigators surveyed an ethnically homogeneous sample of 344 Mexican-origin adolescents (ages 12-15) and their primary caregivers, assessing risks and protective factors for mental health and sleep outcomes. Youth also completed a one-time 21-day daily diary after wave 1. Self-reported measures of youth mental health, sleep, and discrimination across wave 1 and the daily diary were evaluated to compare the cross-sectional (wave 1) and daily associations between discrimination and youth mental health and sleep outcomes. RESULTS Of youth, 88.1% reported at least one incident of lifetime discrimination. Almost one-third had elevated depressive symptoms, 44.5% had probable generalized anxiety disorder, and 50.9% had poor sleep quality. Between-youth correlations at wave 1 and in the daily diary were consistent in that perceived racial discrimination was positively correlated with worse mental health and poorer sleep quality. Smaller within-youth correlations were observed in the daily diary, but there was striking variability in the effect of discrimination across youth. CONCLUSION The present results illustrate the powerful methods of combining yearly and daily time data to investigate how and for whom discrimination-related stressors lead to adverse outcomes. DIVERSITY & INCLUSION STATEMENT We worked to ensure that the study questionnaires were prepared in an inclusive way.

Abstract
OBJECTIVES There is limited qualitative research investigating how risk-mitigation strategies during the COVID-19 pandemic impacted the lives of diverse older adults, who met criteria for mild to severe generalized anxiety or depression and minor to moderate disability. This study aims to address this gap by examining how racially and ethnically diverse older adults with at least mild mental health symptoms and minor physical disability in the United States and Puerto Rico adapted to guidelines during COVID-19. It aims to inform the medical community and policymakers of potential threats to these older adults' well-being given the COVID-19 burden. DESIGN Based on descriptive qualitative inquiry and phenomenological perspectives, we conducted semi-structured interviews over the phone with a racially and ethnically diverse sample of older (age 60+), predominantly minoritized adults (N = 100) in four states and territories across the United States and Puerto Rico in 2021. Interviews were recorded, coded, and analyzed using a thematic analysis approach. RESULTS Findings centered on five themes: (1) Previous experiences with the healthcare system and cultural beliefs related to trust and distrust led to mixed attitudes toward COVID-19 risk-mitigation strategies; (2) Compliance with COVID-19 mitigation strategies ensured safety and addressed fear of illness; (3) Compliance led to isolation due to interrupted social relations; (4) Isolation and disrupted social networks negatively impacted mental health and finances, and (5) Coping strategies and embracing support reduced the effects of social isolation. CONCLUSION This study underscores the importance of increasing support and social connectedness during a pandemic and beyond to ensure the well-being of older adults in racially and ethnically diverse communities. It highlights the resiliency of older adults in identifying strategies to cope with negative impacts. We recommend safeguarding economic security through policy efforts toward financial safety nets during health crises and collaborative approaches with community-based organizations to mitigate social isolation.

Abstract
OBJECTIVE The authors aimed to uncover factors that affect engagement in substance use disorder treatment among Medicaid beneficiaries in New York State. METHODS The authors conducted 40 semistructured interviews with clients, plan administrators, health care providers, and policy leaders directly involved with substance use care in New York State. Data were analyzed with thematic analysis. RESULTS Main themes resulting from analysis of the 40 interviews showed that most stakeholders agreed that a need exists to better integrate psychosocial services into behavioral health care systems; that systemic stigma, stigma from providers, and lack of cultural responsiveness in the substance use care system hinder engagement in and provision of high-quality care; and that rural health care networks with coordinated models benefit clients' engagement in care. CONCLUSIONS Stakeholders involved in care for substance use disorder perceived a lack of integration of resources to meet clients' social needs, the presence of stigma, and low levels of cultural and linguistic capacity as key factors contributing to low engagement in and low quality of care for substance use disorder. Future interventions should address social needs within the therapeutic regimen and modify curricula in clinical training to reduce stigma and increase cultural competence.

Abstract
Simulium takahasii (Rubtsov), which was originally described from Japan, and recorded from Korea and China, is the first among the 19 species of the subgenus Wilhelmia Enderlein recorded from East Asia. It is striking in mating, blood-feeding and ovipositing in captivity and in experimentally transmitting Dirofilaria immitis (Leidy) and Brugia pahangi (Buckley & Edeson), and it is a severe biter of cattle and horses, rarely of humans. Nevertheless, updated information about its morphological characteristics was lacking, making comparisons with related species described from China difficult, since species of the subgenus Wilhelmia are almost indistinguishable from one another, in particular, in their female terminalia, male genitalia and most of larval features. In this study, as many morphological characteristics as possible of S. takahasii based on specimens from Japan are redescribed. New information about many features of this species including the length of the female sensory vesicle against the third palpal segment, number of male upper-eye (large) facets, arrangement of the eight pupal gill filaments, presence or absence of tiny dark setae on the dorsum of the larval abdomen and the number of rows and hooklets of the larval posterior circlet will be useful in evaluating the species status of several Wilhelmia species in China including the species regarded as S. takahasii.

Abstract
Simulium (Gomphostilbia) okinawense Takaoka and S. (G.) tokarense Takaoka, both from the Nansei Islands, Japan, were morphologically reexamined and genetically analysed by using the COI gene sequences. The female, male, pupa and mature larva of the two species are redescribed. Morphological reexamination shows that both species are more similar to species in the S. asakoae species-group than to those in the S. ceylonicum species-group, by having a medium-long female sensory vesicle, yellow tuft hairs (S. (G.) okinawense) or yellow tuft hairs mixed with a few to several dark hairs (S. (G.) tokarense) at the base of the radial vein in the female and male, and medium-long larval postgenal cleft. However, the body of the male ventral plate (viewed ventrally) is parallel-sided (S. (G.) okinawense) or parallelsided or slightly narrowed (S. (G.) tokarense) and not emarginated basally, differing from those of most species in the S. asakoae species-group. Our genetic analysis shows that S. (G.) tokarense is in the S. asakoae species-group, and S. (G.) okinawense formed a separate sister clade with other members of the S. asakoae species-group with high bootstrap support. From the results of morphological and genetic analysis combined, S. (G.) okinawense and S. (G.) tokarense are transferred from the S. ceylonicum species-group to the S. asakoae species-group.

Abstract
(1) Background: Few qualitative studies address diverse older adults' perceptions of COVID-19 vaccination in the United States, including non-English speakers and immigrant populations. This study aims to understand the attitudes of diverse, primarily immigrant older adults in the U.S. toward the COVID-19 vaccine and its influences on their vaccination decision-making. (2) Methods: The research team conducted semi-structured interviews (N = 100) in 2021 focused on understanding ethnically/racially diverse older adults' perceptions of the COVID-19 vaccine. Interviews were recorded, coded, and analyzed using a thematic analysis approach. (3) Results: Thematic analyses identified three themes. (1) Older adults showed mixed attitudes toward the COVID-19 vaccine associated with information consumed and trust in healthcare systems; (2) health concerns and underlying medical conditions were the most influential factors of vaccine uptake; and (3) systemic barriers and trusted figures impacted vaccination decision-making of older adults. (4) Conclusions: Accessible information in diverse languages tailored to the community's fears is needed to combat vaccine mistrust. Vaccine rollout programs need to tackle the fear of vaccine side effects. Attitudes of religious leaders, family members, and physicians considerably influenced vaccine uptake, suggesting their role as trusted members for vaccine messaging for older, primarily immigrant adults. Systemic barriers, namely lack of transportation and inaccessible vaccination sites, contributed to vaccine deterrence.

Abstract
OBJECTIVE The aim was to assess the magnitude of health care disparities in treatment for substance use disorder (SUD) and the role of health plan membership and place of residence in observed disparities in Medicaid Managed Care (MMC) plans in New York City (NYC). DATA SOURCE Medicaid claims and managed care plan enrollment files for 2015-2017 in NYC. RESEARCH DESIGN We studied Medicaid enrollees with a SUD diagnosis during their first 6 months of enrollment in a managed care plan in 2015-2017. A series of linear regression models quantified service disparities across race/ethnicity for 5 outcome indicators: treatment engagement, receipt of psychosocial treatment, follow-up after withdrawal, rapid readmission, and treatment continuation. We assessed the degree to which plan membership and place of residence contributed to observed disparities. RESULTS We found disparities in access to treatment but the magnitude of the disparities in most cases was small. Plan membership and geography of residence explained little of the observed disparities. One exception is geography of residence among Asian Americans, which appears to mediate disparities for 2 of our 5 outcome measures. CONCLUSIONS Reallocating enrollees among MMC plans in NYC or evolving trends in group place of residence are unlikely to reduce disparities in treatment for SUD. System-wide reforms are needed to mitigate disparities.

Abstract
Importance There is limited evaluation of the performance of Medicaid managed care (MMC) private plans in covering substance use disorder (SUD) treatment. Objective To compare the performance of MMC plans across 19 indicators of access, quality, and outcomes of SUD treatment. Design Setting and Participants This cross-sectional study used administrative claims and mandatory assignment to plans of up to 159 016 adult Medicaid recipients residing in 1 of the 5 counties (boroughs) of New York, New York, from January 2009 to December 2017 to identify differences in SUD treatment access, patterns, and outcomes among different types of MMC plans. Data from the latest years were received from the New York State Department of Health in October 2019, and analysis began soon thereafter. Approximately 17% did not make an active choice of plan, and a subset of these (approximately 4%) can be regarded as randomly assigned. Exposures Plan assignment. Main Outcomes and Measures Percentage of the enrollees achieving performance measures across 19 indicators of access, process, and outcomes of SUD treatment. Results Medicaid claims data from 159 016 adults (mean [SD] age, 35.9 [12.7] years; 74 261 women [46.7%]; 8746 [5.5%] Asian, 73 783 [46.4%] Black, and 40 549 [25.5%] White individuals) who were auto assigned to an MMC plan were analyzed. Consistent with national patterns, all plans achieved less than 50% (range, 0%-62.1%) on most performance measures. Across all plans, there were low levels of treatment engagement for alcohol (range, 0%-0.4%) and tobacco treatment (range, 0.8%-7.2%), except for engagement for opioid disorder treatment (range, 41.5%-61.4%). For access measures, 4 of the 9 plans performed significantly higher than the mean on recognition of an SUD diagnosis, any service use for the first time, and tobacco use screening. Of the process measures, total monthly expenditures on SUD treatment was the only measure for which plans differed significantly from the mean. Outcome measures differed little across plans. Conclusions and Relevance The results of this cross-sectional study suggest the need for progress in engaging patients in SUD treatment and improvement in the low performance of SUD care and limited variation in MMC plans in New York, New York. Improvement in the overall performance of SUD treatment in Medicaid potentially depends on general program improvements, not moving recipients among plans.

Abstract
OBJECTIVE To explore how stakeholders responded to research evidence regarding supported employment (e.g., vocational rehabilitation), and ways evidence could be incorporated into policy and action. DATA SOURCES Qualitative data were collected from three stakeholder groups-people with lived experience of mental health challenges, community health advocates, and state health policy makers. STUDY DESIGN This study consisted of two sequential steps. First, three focus groups were conducted after presenting stakeholder groups (inclusive of 22 participants) with simulation data showing that improvement in employment status had a stronger impact on mental health than improvement in education or income for racially/ethnically diverse groups. Second, with guidance from focus group findings, researchers conducted additional in-depth interviews (n = 19) to gain a deeper understanding of the opportunities and challenges related to incorporating these findings into policy and practice. DATA COLLECTION/EXTRACTION METHODS Focus groups and in-depth interviews were conducted, audio recorded, transcribed, and analyzed using a thematic analysis approach. PRINCIPAL FINDINGS People with lived experience described the positive effect of employment in their own life while highlighting the need to increase workplace accommodations and social supports for those with mental health challenges. Across stakeholder groups, participants emphasized the need for linguistic and cultural competence to promote equity in delivery of supported employment programs. Stakeholders also underscored that centralizing existing resources and using evidence-based approaches are crucial for successful implementation. CONCLUSION Implementing effective supported employment programs should focus on meeting the specific needs of target individuals, as many of those needs are not considered in current employment-related programming. Collecting information from diverse users of research demonstrates what other aspects of supported employment are required for the likelihood of successful uptake. Implementation and dissemination efforts need to fortify collaborations and knowledge transfer between stakeholders to optimize supported employment and mental health resources.

Abstract
Simulium ( Simulium) rufibasis Brunetti originally described from India was once considered a geographic generalist widely distributed in the Oriental Region. In this study, the species previously regarded as S. (S.) rufibasis in Taiwan was morphologically re-evaluated and found to be distinguished in the male and pupa from true S. (S.) rufibasis from India. This new species is described as S. ( S.) hehuanense sp. nov. based on a female, a male and their pupal exuviae in Taiwan. This new species is placed in the S. rufibasis subgroup of the S. tuberosum species-group, and is similar to S. (S.) yamatoense Takaoka, Adler & Fukuda from Japan and Korea, but it is barely distinguished by the slenderer forebasitarsi of the female and male. Another new, related species, S. (S.) xiulinense sp. nov., is described based on a male and its pupal exuviae. This new species is distinguished from S. (S.) hehuanense sp. nov. by the number of male upper-eye (large) facets in 20 or 21 vertical columns and 22 horizontal rows (19 vertical columns and 19 horizontal rows in the latter species), and presence of a pair of dorsolateral shiny spots on male abdominal segment 5 (absence in the latter species). Both new species inhabit streams at high elevations (ca, 2,600 m). They differ from S. (S.) sp. (probably S. (S.) arisanum Shiraki) from Taiwan, of the same subgroup, which breeds in streams at low elevations (433-685 m), by the pupal head and thorax covered with tubercles (bare in the latter species).

Abstract
A rare non-sex mosaic abnormality represented by genitalia-like appendages on the ventral surface of abdominal segment 8 of a male black fly collected in Hokkaido, Japan, is reported. The appendages consist of a pair of style-like projections each arising from a coxite-like base, inverted-Y shaped ventral plate-like structure, and isolated round structure. This male was morphologically and molecularly identified as an abnormal form of S. (S.) iwatense (Shiraki), the only species in the Simulium (Simulium) ornatum species-group in Japan, although certain morphological characteristics of this male including the reduced number of uppereye (large) facets and elongate cerci are different from those of S. (S.) iwatense.

Abstract
Abstract
Introduction
Left atrial low-voltage areas (LVAs) are associated with recurrence after radiofrequency catheter ablation of atrial fibrillation (AF). However, the impact of LVAs on recurrence after an empiric pulmonary vein isolation (PVI) plus superior vena cava isolation (SVCI) strategy for non-Paroxysmal AF (PAF) patients remains unclear.
Purpose
We evaluated the impact of LVAs on the recurrence of atrial tachyarrhythmias (ATs)/AF in patients who underwent an empiric SVCI added to the PVI for non-PAF.
Methods
We enrolled 153 consecutive patients with non-PAF who underwent a PVI alone (PVI group; n=51) or empiric PVI plus SVCI (PVI+SVCI group; n=102). Left atrial voltage maps were constructed during sinus rhythm to identify the LVAs (<0.5 mV). No patients underwent a substrate modification of the LVAs. We divided the patients into two groups based on the LVAs (with or without an LVA >5% of the left atrial surface area) and investigated the ATs/AF free survival rate after the initial and multiple procedures.
Results
LVAs were identified in 65% and 73% of the PVI and PVI + SVCI groups, respectively (P=0.319). In the PVI group, the 18-month ATs/AF-free survival was 61% of the patients without LVAs and 27% of patients with LVAs after the initial session (P=0.018) (Figure 1-A). Seventy-two percent of the patients without LVAs and 46% of those with LVAs were free from ATs/AF after multiple sessions (P=0.083) (Figure 1-B). In the PVI+SVCI group, 50% of the patients with LVAs and 61% of those without LVAs had no recurrence after the initial session (P=0.374) (Figure 2-A). Moreover, there was no significant difference in the 18-month ATs/AF-free survival between the patients with and without LVAs after multiple sessions (73% vs. 79%; P=0.520) (Figure 2-B).
Conclusion
A PVI alone strategy for non-PAF patients with LVAs had limited efficacy for the outcomes, even with multiple procedures. However, an SVCI may have the potential to compensate for an impaired outcome in patients with LVAs.

Abstract
Abstract
Background
Door-to-balloon time in patients with ST-elevation myocardial infarction is reported to be an independent predictor of the prognostic implication. However, the effect of door-to-deployment time (DTDT) of venoarterial extracorporeal membrane oxygenation (VA-ECMO) on patients with out-of-hospital cardiac arrest (OHCA) is unclear.
Purpose
This single-center, retrospective, observational study aimed to evaluate the effect of DTDT of VA-ECMO for mortality or neurological outcome of extracorporeal cardiopulmonary resuscitation (ECPR) in patients with cardiogenic OHCA.
Method
This single-center, retrospective, observational study was conducted from January 2008 to April 2019. The primary endpoint was 1-month overall survival measured after ECMO initiation. Moreover, the secondary endpoint was 1-month survival with favorable neurological functions defined as having a cerebral performance category score of 1 or 2.
Result
A total of 3082 patients with OHCA were brought to our institution and 84 received ECPR. Of these, 51 consecutive adult patients with cardiogenic OHCA without sustained return of spontaneous circulation during transport were included in this analysis. Approximately 18 patients (18/51, 35.3%) survived after 1 month and were discharged. Among the survivors, 15 (15/18, 83.3%) were discharged with a favorable neurological outcome. The baseline characteristics between the survivors and non-survivors were not significantly different, except for the initial shockable rhythm [18/18 (100%) versus 28/33 (84.9%), P=0.03]. There were no significant differences between the median time from collapse to hospital arrival [31.0 min (IQR 25.0–31.0) versus 29.0 min (IQR 25.0–39.5), P=0.53] and from call to hospital arrival [28.0 min (IQR 22.0–32.5) versus 27.0 min (IQR 23.3–34.5), P=0.56]. The median DTDT of VA-ECMO was significantly shorter in survivors [13.0 min (IQR 11.5–18.3) versus 21.0 minutes (IQR 15.5–32.0), P=0.01]. The Kaplan–Meier survival analysis showed that the group with a DTDT ≤20 min had a significantly higher 1-month overall survival rate (P<0.01) and survival rate with a favorable neurological outcome (P=0.01) than that with a DTDT >20 minutes. Using the Cox proportional hazards analysis, DTDT ≤20 minutes and bystander-witnessed significantly affected the overall survival rate at 1 month [adjusted hazard ratio (HR), 0.44; 95% confidence interval (CI), 0.20–0.95; P=0.03 and adjusted HR, 0.31; 95% CI, 0.13–0.74; P<0.01, respectively]. Regarding survival rate with a favorable neurological outcome, the result was relatively similar [adjusted HR, 0.46; 95% CI, 0.22–0.96; P=0.04 and adjusted HR, 0.37; 95% CI, 0.16–0.85; P=0.02, respectively].
Conclusion
This study revealed that the DTDT of VA-ECMO is significantly associated with the 1-month mortality and neurological prognosis of patients with cardiogenic OHCA. However, further studies will be required to confirm these findings.

Abstract
This study examines racial/ethnic differences in perceived need for mental health treatment, barriers to treatment receipt, and reasons for dropout. Data are from the Collaborative Psychiatric Epidemiology Studies, a pooled dataset from three U.S. nationally-representative adult samples. Among respondents with a 12-month psychiatric disorder who received no treatment (N = 1417), Asians and Latinos reported lower perceived need than Blacks and Whites, and Latinos reported the fewest attitudinal barriers. Among those with a 12-month disorder who dropped out of treatment, Asians and Latinos gave more reasons for dropping out. Significant interactions of race/ethnicity with other characteristics identified subpopulations with high unmet need.

Abstract
Latinos are underrepresented in clinical trials, where they encounter challenges in participation and a lack of effective recruitment and retention strategies. For Latino migrants with mental health and substance use problems, these challenges are even greater. Analyzing results from a multicenter randomized clinical trial for Latino migrants with mental health and substance use problems in Boston, Massachusetts, USA as well as Madrid and Barcelona, Spain, we describe six retention strategies used to facilitate participant engagement in follow-up assessments, and report the sociodemographic, clinical, and educational factors associated with research assessment completion. Among 341 randomized participants, 77% completed the 12-month follow-up and 75% completed at least 3 of the 4 follow-up assessments. Having a high school diploma, being recruited at community centers versus other sites, and having a less severe mental health condition were significantly associated with completing more follow-up interviews. Rigorous and customized methods reflecting participant's individual context can bolster research assessment completion for diverse Latino populations with behavioral health concerns.

Abstract
Interaction cross sections for ^{42-51}Ca on a carbon target at 280 MeV/nucleon have been measured for the first time. The neutron number dependence of derived root-mean-square matter radii shows a significant increase beyond the neutron magic number N=28. Furthermore, this enhancement of matter radii is much larger than that of the previously measured charge radii, indicating a novel growth in neutron skin thickness. A simple examination based on the Fermi-type distribution, and mean field calculations point out that this anomalous enhancement of the nuclear size beyond N=28 results from an enlargement of the core by a sudden increase in the surface diffuseness of the neutron density distribution, which implies the swelling of the bare ^{48}Ca core in Ca isotopes beyond N=28.

Abstract
Among students receiving behavioral health and special education services, racial/ethnic minority students are consistently overrepresented in settings separate from general classrooms. Once separated, many young people struggle to improve academically and face significant difficulty upon trying to return to a general education setting. Given the complex, ongoing, and multifaceted nature of this challenge, racial/ethnic disproportionality can be identified as a "wicked problem," for which solutions are not easily identified. Here, we describe our community-engaged research efforts, eliciting perspectives from relevant partners in an ongoing dialogue, to better integrate diverse stakeholders' perspectives when attempting to address such disparities. We conducted focus groups and qualitative interviews with members of three stakeholder groups: community-serving organizations, individuals with lived experience of behavioral health conditions, and state-level policymakers, with a shared interest in addressing racial and ethnic disparities. Participant responses illustrated the "wickedness" of this problem and highlighted the need for additional supports for students, families, and school personnel, increased collaboration across relevant systems and agencies, and reduced barriers related to funding. Overall, this methodology bridged differing perspectives to develop, in concert with our partners, a shared language of the problem and a core set of issues to consider when seeking to effect change.

Abstract
Despite efforts to increase the diversity of academia, minority scholars continue to face significant barriers (e.g., higher financial burden, lack of institutional support for research interests, social isolation) that undermine their representation in the field and overall professional success. Researchers have suggested increased mentorship as a means of mitigating these challenges. In 2015, with the support of the Robert Wood Johnson Foundation, a panel of senior investigators met via WebEx to discuss strategies to improve the mentorship of underrepresented scholars. The topics covered by this panel included factors that optimize or challenge mentorship based on personal experience, what is special about mentorship in the context of race/ethnicity, relational dynamics, work-life balance, discrimination, and how to address challenges to the mentoring relationship. The current article provides an overview of the convening and synthesizes the lessons learned by panelists' first-hand experiences of mentoring trainees and junior faculty of color. Authors conclude with recommendations and a description of the social and institutional implications of bolstering the professional support of minority scholars.

Abstract
Osteo-odontokeratoprosthesis (OOKP) is a technique invented by Strampelli in 1963, in which the patient's own tooth root is used to support an optical cylinder. It uses an autologous tooth-bone-periodontal complex to mount an optical cylinder, which is stabilised by overlying autologous buccal mucosa. OOKP involves two, staged procedures done by ophthalmologists and oral surgeons, and the main contribution from the oral surgeon is during the first stage. To date we have done nine first-stage, and completed eight second-stage, OOKP operations in Japan with a mean follow-up of eight years and 11 months by modifying the original method of the oral surgery. All OOKP procedures were unilateral, and canines were selected as the donor teeth. Patients developed ocular blindness as a result of Stevens-Johnson syndrome, ocular cicatricial pemphigoid, and chemical and thermal burns to the cornea and ocular surface. All eight patients who completed the second stage have been stable, and there have been no major perioperative or postoperative oral complications. The patients' visual acuities were stable with no serious complications. Here we report the technical details of the oral contribution to OOKP.

Abstract
This work aims to study the fast-neutron production and moderation for the development of a compact accelerator-based multi-port Boron Neutron Capture Therapy (AB-mBNCT) system. An initial energy distribution and the efficiency of a test moderator assembly (TMA) for fast neutrons from a tungsten (W) target bombarded with a 53 MeV proton beam were measured using organic scintillators. The experimental results were reproduced with reasonable accuracy by simulations using the PHITS code. This paper will discuss about the experimental outcome and the related benchmark calculations by PHITS code.

Abstract
The isospin character of p-n pairs at large relative momentum has been observed for the first time in the ^{16}O ground state. A strong population of the J,T=1,0 state and a very weak population of the J,T=0,1 state were observed in the neutron pickup domain of ^{16}O(p,pd) at 392 MeV. This strong isospin dependence at large momentum transfer is not reproduced by the distorted-wave impulse approximation calculations with known spectroscopic amplitudes. The results indicate the presence of high-momentum protons and neutrons induced by the tensor interactions in the ground state of ^{16}O.

Abstract
Interacting nature between impurity hydrogen atoms and vacancy-type defects in single crystal ZnO was investigated by means of positron annihilation lifetime spectroscopy. In order to clarify the observation of their thermal behavior, the sample was implanted with 1H+ using an electrostatic accelerator. After the implantation, the positron lifetime became shorter, which suggests that the hydrogen atoms were captured by zinc vacancies (VZn) to form vacancy-hydrogen complexes (VZn + nH). The complexes decompose by heat treatment: most of the hydrogen atoms gradually dissociate from VZn + nH in the temperature range 393-773 K. It was also suggested that large vacancy clusters were formed by the agglomeration of smaller clusters during the process of stepwise isochronal annealings at temperatures from 773 to 1073 K, and their decomposition took place at 1173-1373 K. Temperature-dependent thermal behaviors of hydrogen atoms and vacancy-type defects in ZnO are discussed.

Abstract
The nuclear shell structure, which originates in the nearly independent motion of nucleons in an average potential, provides an important guide for our understanding of nuclear structure and the underlying nuclear forces. Its most remarkable fingerprint is the existence of the so-called magic numbers of protons and neutrons associated with extra stability. Although the introduction of a phenomenological spin-orbit (SO) coupling force in 1949 helped in explaining the magic numbers, its origins are still open questions. Here, we present experimental evidence for the smallest SO-originated magic number (subshell closure) at the proton number six in 13-20C obtained from systematic analysis of point-proton distribution radii, electromagnetic transition rates and atomic masses of light nuclei. Performing ab initio calculations on 14,15C, we show that the observed proton distribution radii and subshell closure can be explained by the state-of-the-art nuclear theory with chiral nucleon-nucleon and three-nucleon forces, which are rooted in the quantum chromodynamics.

Abstract
Our research goal is to measure the 7Be(d, p) reaction to shed light on the 7Li problem in the Big-Bang Nucleosynthesis. We are developing an unstable 7Be target for a high-resolution measurement of the 7Be(d, p)8Be reaction. We plan to compare two methods to producethe 7Be target: (1) Activation method, and (2) Implantation method. We performed an activation methodexperiment at the Van de Graaff at Osaka University, and obtained the cross-section data. A second experiment to obtain more accurate data will take place at the Tandem Electrostatic Accelerator, Kobe University. We have also made a 7Be target with implantation method at CRIB, Center for Nuclear Study, Univer-sity of Tokyo. An experiment to measure the (d, p) reaction with the implanted target is scheduled for 2018 at Japan Atomic Energy Agency, tandem facility.
