Abstract

Innovations in organ preservation, surgical technique, and postoperative care have transformed solid organ transplantation. As organ transplantation becomes more common, potential racial, ethnic, and socioeconomic inequities in the referral and selection process are also emerging. Research studies highlight that patients from minoritized and low socioeconomic groups experience lower rates of referrals, reduced access to the transplant waitlist, higher rates of postoperative complications, and higher mortality rates for cardiothoracic (lung/heart) and abdominal (liver/kidney/pancreas) transplants. Yet, the drivers of these inequities are understudied and thus poorly understood. Strategies that address the root causes and mitigate these inequities are urgently needed. The purpose of this manuscript is not to be a systematic review, partially because there is limited research in this area, but to lay a roadmap toward equity in lung transplant. We highlight the available literature on lung transplantation inequities, identify critical needs, and propose strategies for the next steps. Our goal is to urge a call to action for the research community to systematically address the research in lung transplant disparities, and for health systems, organizations, and policymakers to implement the organizational and health system changes to meaningfully reduce these disparities.

Abstract

Background: Adolescent brains are sensitive to stressors. However, under certain circumstances, developmental stress can promote an adaptive phenotype, allowing individuals to cope better with adverse situations in adulthood, thereby contributing to resilience. Methods: Sprague Dawley rats (50 males, 48 females) were subjected to adolescent chronic variable stress (adol CVS) for 2 weeks at postnatal day 45. At postnatal day 85, a group was subjected to single prolonged stress (SPS). After a week, animals were evaluated in an auditory-cued fear conditioning paradigm, and neuronal recruitment during reinstatement was assessed by Fos expression. Patch clamp electrophysiology (17–35 cells/group) was performed in male rats to examine physiological changes associated with resilience. Results: Adol CVS blocked fear potentiation evoked by SPS. We observed that SPS impaired extinction (males) and enhanced reinstatement (both sexes) of the conditioned freezing response. Prior adol CVS prevented both effects. SPS effects were associated with a reduction of infralimbic (IL) cortex neuronal recruitment after reinstatement in males and increased engagement of the central amygdala in females, both also prevented by adol CVS, suggesting different neurocircuits involved in generating resilience between sexes. We explored the mechanism behind reduced IL recruitment in males by studying the intrinsic excitability of IL pyramidal neurons. SPS reduced excitability of IL neurons, and prior adol CVS prevented this effect. Conclusions: Our data indicate that adolescent stress can impart resilience to the effects of traumatic stress on neuroplasticity and behavior. Our data provide a mechanistic link behind developmental stress-induced behavioral resilience and prefrontal (IL) cortical excitability in males.

Abstract

Abstract Background In the context of rising healthcare costs, formal education on treatment-related financial hardship is lacking in many medical schools, leaving future physicians undereducated and unprepared to engage in high-value care. Method We performed a prospective cohort study to characterize medical student knowledge regarding treatment-related financial hardship from 2019 to 2020 and 2020–2021, with the latter cohort receiving a targeted educational intervention to increase cost awareness. Using Kirkpatrick’s four-level training evaluation model, survey data was analyzed to characterize the acceptability of the intervention and the impact of the intervention on student knowledge, attitudes, and self-reported preparedness to engage in cost-conscious care. Results Overall, N = 142 medical students completed the study survey; 61 (47.3%) in the non-intervention arm and 81 (66.4%) in the intervention arm. Of the 81 who completed the baseline survey in the intervention arm, 65 (80.2%) completed the immediate post-intervention survey and 39 (48.1%) completed the two-month post-intervention survey. Following the educational intervention, students reported a significantly increased understanding of common financial terms, access to cost-related resources, and level of comfort and preparedness in engaging in discussions around cost compared to their pre-intervention responses. The majority of participants (97.4%) reported that they would recommend the intervention to future students. A greater proportion of financially stressed students reported considering patient costs when making treatment decisions compared to their non-financially stressed peers. Conclusions Targeted educational interventions to increase cost awareness have the potential to improve both medical student knowledge and preparedness to engage in cost-conscious care. Student financial stress may impact high-value care practices. Robust curricula on high-value care, including treatment-related financial hardship, should be formalized and universal within medical school training.

Abstract

Objective: Guidelines informing screening mammography for older women are lacking. This study sought to characterize PCP perspectives on screening mammography for patients aged 75 and older. Methods: This was an exploratory, qualitative study based on semi-structured, one-on-one interviews with PCPs from six clinics affiliated with a tertiary medical center. Two independent coders analyzed interview transcripts and identified themes, subthemes, and representative quotes using inductive analysis methodology. Results: Ten providers completed interviews. The majority (90%) of providers reported insufficient evidence to suggest a best practice for screening in this population. Providers relied on shared decision-making with patients, a process facilitated by strong provider-patient relationships. Providers took into consideration factors such as functional status, personal risk of breast cancer, and patient preference. Time constraints disincentivized providers to engage in discussions. Conclusions: PCPs make decisions about screening mammography for older patients on an individualized basis, taking into account patient overall health status and desire for aggressive intervention. They often rely on shared decision-making given unclear clinical guidelines. Practice implications: These findings suggest that fostering strong provider-patient relationships, addressing patient knowledge gaps, and compensating providers for time spent on counseling may facilitate cost-efficient and patient-centered utilization of screening mammography.

Abstract

Numerical simulation of the motion of a cuboidal solid body induced by a propagating shock wave was conducted by using the overset grid functionality of OpenFOAM (v1712). A body-fitted grid associated with the moving body was overlapped with a background Cartesian grid fixed in space, and transient, three-dimensional, inviscid flows around the moving body were simulated coupled with the six-degrees-of-freedom motion of the solid body. The results from the present simulation were compared with those from shock tube experiments, in which the shock-induced motion of a cuboidal solid body floating in air and the flow field around the solid body were visualized using the shadowgraph technique and recorded by a high-speed video camera with a frame rate of 20,000 frames per second. The good agreement found between the numerical and experimental results for the translational and angular displacements of the shocked solid body indicates the capability of OpenFOAM to predict the shock-induced motion of a solid body.

Abstract

Background Telehealth is an increasingly important component of health care delivery in response to the COVID-19 pandemic. However, well-documented disparities persist in the use of digital technologies. Objective This study aims to describe smartphone and internet use within a diverse sample, to assess the association of smartphone and internet use with markers of health literacy and health access, and to identify the mediating factors in these relationships. Methods Surveys were distributed to a targeted sample designed to oversample historically underserved communities from April 2017 to December 2017. Multivariate logistic regression was used to estimate the association of internet and smartphone use with outcomes describing health care access and markers of health literacy for the total cohort and after stratifying by personal history of cancer. Health care access was captured using multiple variables, including the ability to obtain medical care when needed. Markers of health literacy included self-reported confidence in obtaining health information. Results Of the 2149 participants, 1319 (61.38%) were women, 655 (30.48%) were non-Hispanic White, and 666 (30.99%) were non-Hispanic Black. The median age was 51 years (IQR 38-65). Most respondents reported using the internet (1921/2149, 89.39%) and owning a smartphone (1800/2149, 83.76%). Compared with the respondents with smartphone or internet access, those without smartphone or internet access were more likely to report that a doctor was their most recent source of health information (344/1800, 19.11% vs 116/349, 33.2% for smartphone and 380/1921, 19.78% vs 80/228, 35.1% for internet, respectively; both P Conclusions We describe widespread use of digital technologies in a community-based cohort, although disparities persist. In this cohort, smartphone ownership was significantly associated with ability to obtain needed medical care, suggesting that the use of smartphone technology may play a role in increasing health care access. Similarly, major illnesses such as cancer have the potential to amplify health engagement. Finally, special emphasis must be placed on reaching patient populations with limited digital access, so these patients are not further disadvantaged in the new age of telehealth.

Abstract

Background The North Carolina Breast and Cervical Cancer Control Program (NC BCCCP) provides breast cancer screening services to underserved women to mitigate disparities in access to care. The authors sought to characterize this understudied population. Methods Women 21 years old or older who underwent their first breast cancer screen through NC BCCCP from 2008 to 2018 were included. Demographic factors associated with the timeline of care and odds of a breast cancer diagnosis were identified with negative binomial and logistic regression, respectively. Results Of the 88,893 women identified, 45.5% were non-Hispanic (NH) White, 30.9% were NH Black, 19.6% were Hispanic, 1.7% were American Indian, and 1.1% were Asian. Breast cancer was diagnosed in 2.5% of the women (n = 2255). Hispanic women were the least likely to be diagnosed with breast cancer (odds ratio vs NH White women, 0.40; 95% confidence interval [CI], 0.34-0.47). Among patients with breast pathology, the median time to diagnosis was 19 days (interquartile range [IQR], 10-33 days), and the time to treatment was 33 days (IQR, 19-54 days). After adjustments, a longer time to diagnosis was significantly associated with age (incidence rate ratio [IRR], 1.01; 95% CI, 1.01-1.02) and being NH Black (vs NH White; IRR, 1.17; 95% CI, 1.06-1.29). A longer time to treatment was significantly associated with age (IRR, 1.01; 95% CI, 1.01-1.01), being NH Black (vs NH White; IRR, 1.20; 95% CI, 1.10-1.31), and being Hispanic (vs NH White; IRR, 1.22; 95% CI, 1.05-1.41). Conclusions NC BCCCP participants with breast cancer received treatment within approximately 1 month of presentation, and this finding aligns with quality care benchmarks. Nevertheless, racial/ethnic disparities in timeliness of care persist, and this suggests opportunities for improvement. Lay summary This review of approximately 90,000 participants in a breast cancer screening program for uninsured and underinsured women highlights the importance of safety net programs in providing timely care to underserved patients. The authors found that the North Carolina Breast and Cervical Cancer Control Program met timeliness benchmarks from the Centers for Disease Control and Prevention across all racial/ethnic groups. However, non-Hispanic Black women experienced relative delays in the time to diagnosis, and both non-Hispanic Black women and Hispanic women experienced relative delays in the time to treatment. These findings demonstrate how racial/ethnic disparities in the timeliness of care can persist even within a program intended to reduce barriers to access.

Abstract

PURPOSE: Although financial toxicity is a well-documented aspect of cancer care, little is known about how patients narratively characterize financial experiences related to breast cancer treatment. We sought to examine these patient experiences through mixed methods analysis. METHODS: Women (≥ 18 years old) with a history of breast cancer were recruited from the Love Research Army and Sisters Network to complete an 88-item electronic survey including an open-ended response. Quantitative data were used to sort and stratify responses to the open-ended question, which comprised the qualitative data evaluated here. Descriptive statistics and qualitative content analysis were used to evaluate the financial costs and other burdens resulting from breast cancer surgery. RESULTS: In total, 511 respondents completed the survey in its entirety and wrote an open-ended response. Participants reported significant financial burden in different categories including direct payments for medical care and indirect costs such as lost wages and travel expenses. Treatment-related costs burdened participants for years after diagnosis, forming a financial arc for many participants. Discrepancies existed between the degree of financial burden reported on multiple-choice questions and participants’ corresponding open-ended descriptions of financial burden. Participants described a lack of communication surrounding costs with their providers and difficulty negotiating payments with insurance. CONCLUSION: Breast cancer care can result in ongoing financial burden years after diagnosis among all patients, even those with adequate insurance patient populations.

Abstract

This volume combines the papers held at the Minerva Center's'Research on Israel and Aram in Biblical Times'conference (Leipzig 2018) on the subject of writing and re-writing history by deliberate destruction in the regions of Syria, Palestine, and Mesopotamia. An international group of scholars studies the subject using a multi-perspective and interdisciplinary approach. Archeological studies, ancient Near Eastern studies, and biblical studies focused on the destruction of ancient sites in Israel and Judah in the 1st millennium BC. The perspective of the defeated Israelites, Jerusalemites, and Judeans is described in detail in the Old Testament and in postbiblical literature and shows that the destructions in the past were a cultural and identity creator of the first magnitude. The longue durée of the practice of reshaping the past through the deliberate destruction of a cultural heritage in order to shape the present according to current interests becomes evident based on the Neo-Assyrian Empire's practice up to the modern era and is demonstrated by the example of the Arabian-Muslim conquest of Aram as well as current Turkish politics.

Abstract

Takayoshi Oshima analyses the two most important Babylonian wisdom texts: Ludlul Bēl Nēmeqi (also known as the Babylonian Job or the Babylonian Righteous Sufferer) and the so-called Babylonian Theodicy. On the basis of the hitherto published as well as newly available, unpublished cuneiform manuscripts, the author establishes a new critical text for each poem and gives an English translation. He offers detailed philological and critical notes to the texts, discussing both the textual and the interpretive issues evoked by individual words and passages. In addition, however, each poem is preceded by a lengthy discussion of its origins, intention, and plot, as well as by more general considerations of its cultural and historical background, including short but important observations on the relationship to Old Testament wisdom literature.

Abstract

101 Background: Overall breast cancer mortality in the US has declined since 1990, but racial/ethnic disparities have worsened. Since 1992, NC BCCCP has provided free/low-cost breast cancer screening to underserved women as part of a national effort by the Centers for Disease Control and Prevention (CDC) to mitigate these disparities. We sought to characterize and evaluate benchmarks for this previously unstudied, state-level cohort. Methods: We identified women ≥18y who underwent their first breast cancer screening via NC BCCCP from 2009-2018. Univariate analysis was used to compare differences in timeline of care and rates of breast pathology (i.e., cancer or atypia) by race/ethnicity and age. Logistic and negative binomial regression were used to identify factors associated with cancer diagnosis and time from enrollment to diagnosis (TTD) and treatment (TTT), respectively. Results: 88,893 women with complete records were identified (median age 50y, IQR 44-56): 45.5% were Non-Hispanic (NH) white, 30.9% NH black, 19.5% Hispanic, 1.7% American Indian (AI), and 1.1% Asian. Overall participation peaked in 2012 but steadily increased among Hispanic women over time (p < 0.001). Breast pathology was diagnosed in 2,016 (2.3%) women, with rates ranging from 1% in Hispanic women to 2.7% in NH whites. After adjustment, Hispanic women were least likely (vs NH white women: OR 0.40; 95% CI 0.34-0.47) to be diagnosed with breast cancer. Median TTD was 19d and TTT was 33d, both within the CDC’s 60d standard. In univariate analyses, women < 50 had shorter TTD (median 18d vs 21d) and TTT (median 30d vs 35d) vs women ≥50 (both p < 0.01), and there were no significant differences by race/ethnicity or between women with atypia vs cancer. In multivariate models, however, older age and NH black race were associated with longer TTD and TTT. Conclusions: NC BCCCP meets national quality benchmarks for TTD and TTT. These data also highlight broader opportunities to achieve racial/ethnic parity and improve equity for breast cancer prevention. [Table: see text]

Abstract

A new shock tube system for the study of shock wave interaction with a solid body floating in the air has been developed. The system consists of a horizontally placed shock tube and a solid-body injecting device, which is mounted on the floor of the test section of the shock tube. A solid body initially placed on the shock tube floor was tossed into the air with the injecting device and then collided with a planar shock wave, which is generated by rapturing the diaphragm between the driver and the driven sections of the shock tube. By tuning the rapturing time of the diaphragm, we can make the shock wave interact with the solid body when it reaches the top of its trajectory almost at rest. In order to demonstrate the applicability of the present system, the shock-induced motion of a hexahedral solid body and the flow field around it were recorded using the shadowgraph technique coupled with a high-speed video camera. Representative results from the present experiments are reported in this paper.

Abstract

The eighteen articles collected in this volume are the results of the international workshop,'Teaching Morality in Antiquity: Wisdom Texts, Oral Traditions, and Images,'held at the Bibliotheca Albertina of the University of Leipzig between November 29th and December 1st, 2016 with the financial support of the Deutsche Forschungsgemeinschaft. During the workshop, fruitful discussions on diverse issues related to the theme'wisdom texts and morality'developed regarding biblical wisdom texts and their parallels from the ancient Egypt, ancient Mesopotamia, and the ancient Levant - more specifically: moral messages and rhetoric in wisdom texts; the dissemination of wisdom teachings; teachings about the divine realm as the core of moral principles or human social order; visualization of divine authority; questions of theodicy; and modern analyses of ancient morality through the eyes of cognitive science.

Abstract

The fascinating interfacial transport properties at the LaAlO3/SrTiO3 heterointerface have led to intense investigations of this oxide system. Exploiting the large dielectric constant of SrTiO3 at low temperatures, tunability in the interfacial conductivity over a wide range has been demonstrated using a back-gate device geometry. In order to understand the effect of back-gating, it is crucial to assess the interface band structure and its evolution with external bias. In this study, we report measurements of the gate-bias dependent interface band alignment, especially the confining potential profile, at the conducting LaAlO3/SrTiO3 (001) heterointerface using soft and hard x-ray photoemission spectroscopy in conjunction with detailed model simulations. Depth-profiling analysis incorporating the electric field dependent dielectric constant in SrTiO3 reveals that a significant potential drop on the SrTiO3 side of the interface occurs within ~2 nm of the interface under negative gate-bias. These results demonstrate gate control of the collapse of the dielectric permittivity at the interface, and explain the dramatic loss of electron mobility with back-gate depletion.

Abstract

Boron Neutron Capture Therapy (BNCT) is a radiotherapy for the treatment of intractable cancer. In BNCT precise determination of 10B concentration in whole blood sample before neutron irradiation of the patient, as well as accurate neutron dosimetry, is crucial for control of the neutron irradiation time. For this purpose ICP-AES and neutron induced prompt γ-ray analysis are generally used. In Ibaraki Neutron Medical Research Center (iNMRC), an intense proton beam will be accelerated up to 8 MeV, which can also be used for Charged Particle Activation Analysis (CPAA). Thus, in this study, we apply the CPAA utilizing the proton beam to non-destructive and accurate determination of 10B concentration in whole blood sample. A CPAA experiment is performed by utilizing an 8 MeV proton beam from the tandem accelerator of Nuclear Science Research Institute in Japan Atomic Energy Agency. The 478 keV γ-ray of 7Be produced by the 10B(p, α)7Be reaction is used to quantify the 10B in human blood. The 478 keV γ-ray intensity is normalized by the intensities of the 847 keV and 1238 keV γ-rays of 56Co originating from Fe in blood. The normalization methods were found to be linear in the range of 3.27 μg 10B/g to 322 μg 10B/g with correlation coefficients of better than 0.9999.

Abstract

The late W.G. Lambert (1926-2011) was one of the foremost Assyriologists of the latter part of the twentieth century. His principle legacy is a large number of superb critical editions of Babylonian literary compositions. Many of the texts he edited were on religious and mythological subjects. He will always be remembered as the editor of the Babylonian Job ( Ludlul bel nemeqi, also known as the Poem of the Righteous Sufferer), the Babylonian Flood Story ( Atra-hasis) and the Babylonian Creation Epic ( Enuma elish). Decades of deep engagement with these and other ancient Mesopotamian texts gave direction to much of his research and led him to acquire a deep knowledge of ancient Mesopotamian religion and mythology. The present book is a collection of twenty-three essays published by the scholar between the years 1958 and 2004. These endure not only as the legacy of one of the greatest authorities in this specialist field, but also because each makes statements of considerable validity and importance. As such, many are milestones in the fields of Mesopotamian religion and mythology.

Abstract

OBJECTIVES: The effectiveness of stool-based colorectal cancer (CRC) screening is contingent on colonoscopy completion in patients with an abnormal fecal immunochemical test (FIT). Understanding system and patient factors affecting follow-up of abnormal screening tests is essential to optimize care for high-risk cohorts. METHODS: This retrospective cohort study was conducted in an integrated safety-net system comprised of 11 primary-care clinics and one Gastroenterology referral unit and included patients 50–75 years, with a positive FIT between April 2012 and February 2015. RESULTS: Of the 2,238 patients identified, 1,245 (55.6%) completed their colonoscopy within 1-year of the positive FIT. The median time from positive FIT to colonoscopy was 184 days (interquartile range 140–232). Of the 13% of FIT positive patients not referred to gastroenterology, 49% lacked documentation addressing their abnormal result or counseling on the increased risk of CRC. Of the patients referred but who missed their appointments, 62% lacked documentation following up on the abnormal result in the absence of a completed colonoscopy. FIT positive patients never referred to gastroenterology or who missed their appointment after referrals were more likely to have comorbid conditions and documented illicit substance use compared with patients who completed a colonoscopy. CONCLUSIONS: Despite access to colonoscopy and a shared electronic health record system, colonoscopy completion after an abnormal FIT is inadequate within this safety-net system. Inadequate follow-up is in part explained by inappropriate screening, but there is an absence of clear documentation and systematic workflow within both primary care and GI specialty care addressing abnormal FIT results.

Abstract

The neutron-induced fission cross section of U234 has been measured at the CERN n_TOF facility relative to the standard fission cross section of U235 from 20 keV to 1.4 MeV and of U238 from 1.4 to 200 MeV. A fast ionization chamber (FIC) was used as a fission fragment detector with a detection efficiency of no less than 97%. The high instantaneous flux and the low background characterizing the n_TOF facility resulted in wide-energy-range data (0.02 to 200 MeV), with high energy resolution, high statistics, and systematic uncertainties bellow 3%. Previous investigations around the energy of the fission threshold revealed structures attributed to β-vibrational levels, which have been confirmed by the present measurements. Theoretical calculations have been performed, employing the talys code with model parameters tuned to fairly reproduce the experimental data.

RADIATIVE NEUTRON CAPTURE, NEUTRON TIME OF FLIGHT
Abstract

Background: The design of new nuclear reactors and transmutation devices requires to reduce the present neutron cross section uncertainties of minor actinides. Purpose: Improvement of the Am243(n,γ) cross section uncertainty. Method: The Am243(n,γ) cross section has been measured at the n-TOF facility at CERN with a BaF2 total absorption calorimeter, in the energy range between 0.7 eV and 2.5 keV. Results: The Am243(n,γ) cross section has been successfully measured in the mentioned energy range. The resolved resonance region has been extended from 250 eV up to 400 eV. In the unresolved resonance region our results are compatible with one of the two incompatible capture data sets available below 2.5 keV. The data available in EXFOR and in the literature have been used to perform a simple analysis above 2.5 keV. Conclusions: The results of this measurement contribute to reduce the Am243(n,γ) cross section uncertainty and suggest that this cross section is underestimated up to 25% in the neutron energy range between 50 eV and a few keV in the present evaluated data libraries.

Abstract

The neutron-induced fission cross section of Np237 was experimentally determined at the high-resolution and high-intensity facility n-TOF, at CERN, in the energy range 100 keV to 9 MeV, using the U235(n,f) and U238(n,f) cross section standards below and above 2 MeV, respectively. A fast ionization chamber was used in order to detect the fission fragments from the reactions and the targets were characterized as far as their mass and homogeneity are concerned by means of α spectroscopy and Rutherford backscattering spectroscopy respectively. Theoretical calculations within the Hauser-Feshbach formalism have been performed, employing the empire code, and the model parameters were tuned in order to successfully reproduce the experimental fission cross-sectional data and simultaneously all the competing reaction channels.

Abstract

The CERN Neutron Time-Of-Flight (n-TOF) facility is well suited to measure small neutron-induced fission cross sections, as those of subactinides. The cross section ratios of {sup nat}Pb and {sup 209}Bi relative to {sup 235}U and {sup 238}U were measured using PPAC detectors. The fragment coincidence method allows to unambiguously identify the fission events. The present experiment provides the first results for neutron-induced fission up to 1 GeV for {sup nat}Pb and {sup 209}Bi. A good agreement with previous experimental data below 200 MeV is shown. The comparison with proton-induced fission indicates that the limiting regime where neutron-induced and proton-induced fission reach equal cross section is close to 1 GeV.

Abstract

Annealing-temperature dependence of the thermal stability and chemical bonding states of AlO x N y /SiO 2 /Si gate stacks grown by metalorganic chemical vapor deposition (MOCVD) using new chemistry was investigated by synchrotron radiation photoemission spectroscopy (SRPES). Results have confirmed the formation of the AlN and AlNO compounds in the as-deposited samples. Annealing the AlO x N y samples in N 2 ambient in 600–800 °C promotes the formation of SiO 2 component. Meanwhile, there is no formation of Al–O–Si and Al–Si binding states, suggesting no interdiffusion of Al with the Si substrate. A thermally induced reaction between Si and AlO x N y to form volatile SiO and Al 2 O is suggested to be responsible for the full disappearance of the Al component that accompanies annealing at annealing temperature of 1000 °C. The released N due to the breakage of the Al–N bonding will react with the SiO 2 interfacial layer and lead to the formation of the Si 3 –N–O/Si 2 –N–O components at the top of Si substrate. These results indicate high temperature processing induced evolution of the interfacial chemistry and application range of AlO x N y /Si gate stacks in future CMOS devices.

Abstract

Three-day rearing experiments were conducted to study the effect of turbulence on the feeding intensity and survival of pelagic larvae of Japanese flounder Paralichthys olivaceus. Four levels of turbulence as control (10(-7.2) m2 s(-3)), low (10(-6.2) m2 s(-3)), mid (10(-5.6) m2 s(-3)) and high (10(-5.0) m2 s(-3)) were set by changing the flow rate of water pumped through pipes set on the bottom of the tanks. In B-stage larvae, defined as having buds of elongated dorsal fin rays, the feeding intensity and growth were higher in the low and mid turbulence levels, while survival was highest in the control level. Most of the larvae surviving in the control level, however, were judged to be in a seriously starved condition leading to subsequent high mortality. Because the three-day span of the rearing experiments was thought to be a little shorter than the periods before starvation-induced, high mortality occurs. In contrast, for D-stage larvae, their feeding and growth were optimal in the control and low levels. Feeding was more adversely affected in the high level for D-stage larvae compared with B-stage larvae. This is probably due to the compressed body shape and elongated dorsal fin rays of D-stage larvae, which may be more strongly affected by turbulence and, as a consequence, the larval feeding behaviour such as pursuit and capture of prey organisms becomes less efficient than in lower turbulence. Considering the vertical distribution of B and D-stage larvae in the oceanic water column, the optimum turbulence level range found in the present study corresponded to a wind speed of 7-10 m s(-1). Therefore, moderate weather conditions of this wind speed range are considered to potentially enhance survival of early larval stages of P. olivaceus.

Abstract

The vortex-chirality control in mesoscopic disk magnets is demonstrated using photoelectron emission microscopy (PEEM). The x-ray magnetic circular dichroism and PEEM observation reveals that the vortex chirality in the designed devices was perfectly controlled by an external applied magnetic field.

Abstract

We have investigated chemical-state-resolved in-depth profiles of SiO2/SiN stack films using angular-dependent photoemission spectroscopy and maximum-entropy method (MEM). MEM enables to reproduce the gate-stack structure from angular-dependence of core-level spectra, and it is utilized to determine atomic concentration of the interfacial layer. In-depth profile of the SiO2/SiN stack film reveals that the SiO2 layer is distributed in the surface region and that the SiN layer is partly oxidized, which is well related to nitrogen bonding states analyzed by angular-dependence of N 1s core-level spectra.
