Abstract

We present angle-resolved photoemission measurements for ultrathin In films on Si(111). Depending on the coverage, this system self-organizes into a metallic monolayer with either 4x1 or sqrt7 x sqrt3 symmetry relative to the substrate. Electronically, they behave like ideal one- and two-dimensional electron gases (1DEG and 2DEG), respectively. The 4x1 system has atomic chains of In whose energy bands disperse only parallel to the chains, while for the sqrt7 x sqrt3 system, the dominant reciprocal space features (in both diffraction and bandstructure) resemble a pseudo-square lattice with only weaker secondary features relating to the sqrt7 x sqrt3 periodicity. In both materials the electrons show coupling to the structure. The 1DEG couples strongly to phonons of momentum 2kF, leading to an 8x"2" Peierls-like insulating ground state. The 2DEG appears to be partially stabilized by electron gap formation at the sqrt 7 x sqrt3 zone boundary.

Abstract

A neural architecture to efficiently coordinate the transitions of state variables (states) over a graph is proposed. We consider the coordination of the time evolution of the state variables associated with the nodes on a graph. The states are associated with physical attributes of agents, e.g., the speed and/or location of vehicles. Efficient coordination then corresponds to the optimization of dynamics (how fast do vehicles travel) that may be subject to constraints (travel must be collision-free). The aim of this paper is (i) the formulation of learnable constrained dynamics which governs the transition of states under constraints over a graph and (ii) to show its industrial application. Firstly, we formulate continuous ordinary differential equations (ODEs), namely forward propagation of state transitions over a graph and backward propagation to optimize model parameters for the learnable constrained dynamics. Discretization of these continuous ODEs results in the neural architecture CoordiNet. Secondly, as an application of CoordiNet, we address a traffic coordination problem by learning constrained dynamics such that vehicles can travel as fast as possible without collisions. Simulation experiments of traffic coordination confirm that our method maximizes the vehicles' speed states while avoiding collisions.

Abstract

Shouta Miyatake,1 Yuko Shimizu-Motohashi,2 Shin’ichi Takeda,1 Yoshitsugu Aoki1 1Department of Molecular Therapy, National Institute of Neuroscience, National Center of Neurology and Psychiatry, Kodaira, Tokyo, Japan; 2Department of Child Neurology, National Center Hospital, National Center of Neurology and Psychiatry, Kodaira, Tokyo, Japan Abstract: Duchenne muscular dystrophy (DMD), an incurable and a progressive muscle wasting disease, is caused by the absence of dystrophin protein, leading to recurrent muscle fiber damage during contraction. The inflammatory response to fiber damage is a compelling candidate mechanism for disease exacerbation. The only established pharmacological treatment for DMD is corticosteroids to suppress muscle inflammation, however this treatment is limited by its insufficient therapeutic efficacy and considerable side effects. Recent reports show the therapeutic potential of inhibiting or enhancing pro- or anti-inflammatory factors released from DMD skeletal muscles, resulting in significant recovery from muscle atrophy and dysfunction. We discuss and review the recent findings of DMD inflammation and opportunities for drug development targeting specific releasing factors from skeletal muscles. It has been speculated that nonsteroidal anti-inflammatory drugs targeting specific inflammatory factors are more effective and have less side effects for DMD compared with steroidal drugs. For example, calcium channels, reactive oxygen species, and nuclear factor-κB signaling factors are the most promising targets as master regulators of inflammatory response in DMD skeletal muscles. If they are combined with an oligonucleotide-based exon skipping therapy to restore dystrophin expression, the anti-inflammatory drug therapies may address the present therapeutic limitation of low efficiency for DMD.

Abstract

Objective Stillbirth is a potentially preventable complication of pregnancy. Identifying women at high risk of stillbirth can guide decisions on the need for closer surveillance and timing of delivery in order to prevent fetal death. Prognostic models have been developed to predict the risk of stillbirth, but none has yet been validated externally. In this study, we externally validated published prediction models for stillbirth using individual participant data (IPD) meta-analysis to assess their predictive performance. Methods MEDLINE, EMBASE, DH-DATA and AMED databases were searched from inception to December 2020 to identify studies reporting stillbirth prediction models. Studies that developed or updated prediction models for stillbirth for use at any time during pregnancy were included. IPD from cohorts within the International Prediction of Pregnancy Complications (IPPIC) Network were used to validate externally the identified prediction models whose individual variables were available in the IPD. The risk of bias of the models and cohorts was assessed using the Prediction study Risk Of Bias ASsessment Tool (PROBAST). The discriminative performance of the models was evaluated using the C-statistic, and calibration was assessed using calibration plots, calibration slope and calibration-in-the-large. Performance measures were estimated separately in each cohort, as well as summarized across cohorts using random-effects meta-analysis. Clinical utility was assessed using net benefit. Results Seventeen studies reporting the development of 40 prognostic models for stillbirth were identified. None of the models had been previously validated externally, and the full model equation was reported for only one-fifth (20%, 8/40) of the models. External validation was possible for three of these models, using IPD from 19 cohorts (491 201 pregnant women) within the IPPIC Network database. Based on evaluation of the model development studies, all three models had an overall high risk of bias, according to PROBAST. In the IPD meta-analysis, the models had summary C-statistics ranging from 0.53 to 0.65 and summary calibration slopes ranging from 0.40 to 0.88, with risk predictions that were generally too extreme compared with the observed risks. The models had little to no clinical utility, as assessed by net benefit. However, there remained uncertainty in the performance of some models due to small available sample sizes. Conclusions The three validated stillbirth prediction models showed generally poor and uncertain predictive performance in new data, with limited evidence to support their clinical application. The findings suggest methodological shortcomings in their development, including overfitting. Further research is needed to further validate these and other models, identify stronger prognostic factors and develop more robust prediction models. (c) 2021 The Authors.

Abstract

In the subtropical North Pacific, the east‐west gradient of iron deposition as atmospheric Asian dust strongly affects the zonal distribution of biological N2 fixation activity in numerical models, but the in‐situ relationship at a basin‐scale is not well examined. We examined the trans‐Pacific zonal variation in N2 fixation activity on 23°N in summer along with environmental parameters that potentially influence diazotrophy. Dissolved inorganic iron (DFe) was consistently low (<0.4 nM) throughout the transect. The atmospheric dust iron (dust‐Fe) flux increased westward, whereas phosphate and labile phosphoric monoesters in the surface decreased westward. N2 fixation varied between 34.6 and 298 μmol‐N m−2 d−1 and was high (>200 μmol‐N m−2 d−1) in the central area (150–180°W). N2 fixation rates significantly increased with dust‐Fe input only in the western area (137–180°E), whereas the contribution of DFe diffused from below the euphotic zone was often larger in the eastern area (120–170°W). N2 fixation was considerably low in the phosphate‐depleted western area despite the excess amount of iron relative to phosphate, and it increased with the labile phosphoric monoesters stock. These indicated that N2 fixation was primarily limited by phosphorus in the western area, though this activity also increased with iron supply from dust, likely due to phosphorus‐iron co‐limitation. In contrast, in the phosphorus‐repleted eastern area, iron supplied from dust and below the euphotic zone appeared to limit N2 fixation. Overall, N2 fixation in the subtropical North Pacific was likely limited by zonally different factors relating to iron and phosphorus availability. Plain Language Summary: N2 fixation, a process that converts N2 gas into ammonia, substantially affects biological production in subtropical ecosystems, where nitrogenous nutrients are scarce. The availability of both iron and phosphorus are primary factors controlling the growth of N2‐fixing organisms. In North Pacific subtropical waters, iron input as atmospheric Asian dust is considered to control the east‐west variation in N2 fixation; however, their relationship is not well‐examined. Here, we investigated the trans‐Pacific distribution of N2 fixation activity with iron and phosphorus availability. Our results show that dust input correlates with N2 fixation in the western area (137–180°E), which is in contrast with the eastern area (120–170°W), where vertically diffused iron was also important. In the phosphate‐depleted western area, N2 fixation positively correlated with the proxies of phosphorus supply, suggesting phosphorus limitation. This indicates phosphorus availability substantially controls the zonal distribution of N2 fixation in the subtropical North Pacific through co‐limitation with iron. The limitations are relaxed in the central area (150–180°W), likely due to elevated nutrient supply caused by bottom topography, resulting in a peak in N2 fixation. Therefore, the dynamics of both iron and phosphorus must be considered simultaneously to predict the response of N2 fixation to environmental changes.

Abstract

This article outlines Kyoto Fusioneering’s (KF’s) initial engineering and development activities for its self-cooled lithium lead-type blanket: Self-Cooled Yuryo Lithium-Lead Advanced (SCYLLA©). We provide details on overall design, including an initial tritium breeding ratio (TBR) assessment via neutronics analysis, as well as the status of SCYLLA©-relevant R&D. This includes silicon carbide composite (SiCf/SiC) manufacturing techniques, tritium extraction, materials compatibility, and heat transfer, which are being explored via collaboration with Kyoto University. Results of previous work in relation to this R&D are presented. Permeability coefficients indicate a promising property of SiCf/SiC tritium hermeticity at high temperatures. Tritium extraction technology via vacuum sieve tray (VST) is shown to be demonstrated at engineering scale. A local TBR of up to 1.4 can be achieved with the SCYLLA© configuration. Fabrication methods for various SiCf/SiC components including the blanket module, heat exchanger, and flow path components are provided. A tritium compatible high-temperature SiCf/SiC heat exchanger is discussed. Commercial viability and reactor adaptability are considered as a theme throughout. Finally, KF’s plans to build a facility for demonstration reactor relevant testing of a SCYLLA© prototype in the mid-2020s, which will provide a significant step toward commercial fusion energy, are presented.

No. of bitstreams: 0 Previous issue date: 2020-07-01 Medical Research Council Canada National Institute for Health Research Objectives: To develop consensus definitions for the core outcome set for pre-eclampsia. Study design: Potential definitions for individual core outcomes were identified across four formal definition development initiatives, nine national and international guidelines, 12 Cochrane systematic reviews, and 79 randomised trials. Eighty-six definitions were entered into the consensus development meeting. Ten healthcare professionals and three researchers, including six participants who had experience of conducting research in low- and middle-income countries, participated in the consensus development process. The final core outcome set was approved by an international steering group. Results: Consensus definitions were developed for all core outcomes. When considering stroke, pulmonary oedema, acute kidney injury, raised liver enzymes, low platelets, birth weight, and neonatal seizures, consensus definitions were developed specifically for low- and middle-income countries because of the limited availability of diagnostic interventions including computerised tomography, chest x-ray, laboratory tests, equipment, and electroencephalogram monitoring. Conclusions: Consensus on measurements for the pre-eclampsia core outcome set will help to ensure consistency across future randomised trials and systematic reviews. Such standardization should make research evidence more accessible and facilitate the translation of research into clinical practice.

Abstract

Yoshiaki Tsuboko,1 Shinhiro Takeda,1,2 Seiji Mii,1 Keiko Nakazato,1 Keiji Tanaka,2 Eiji Uchida,3 Atsuhiro Sakamoto11Department of Anesthesiology, Nippon Medical School, 2Intensive Care Unit and Cardiac Care Unit, Nippon Medical School Hospital, 3Department of Surgery, Nippon Medical School, Tokyo, JapanBackground: The efficacy of sivelestat in the treatment of acute lung injury/acute respiratory distress syndrome (ALI/ARDS) has not been established. In part, this is due to the wide variety of factors involved in the etiology of ALI/ARDS. In this study, we examined the efficacy of sivelestat in patients with ALI/ARDS associated with abdominal sepsis.Methods: The subjects were 49 patients with ALI/ARDS after surgery for abdominal sepsis. The efficacy of sivelestat was retrospectively assessed in two treatment groups, ie, a sivelestat group (n = 34) and a non-sivelestat group (n = 15).Results: The sivelestat group showed significant improvements in oxygenation, thrombocytopenia, and multiple organ dysfunction score. The number of ventilator days (6.6 ± 6.1 versus 11.1 ± 8.4 days; P = 0.034) and length of stay in the intensive care unit (8.5 ± 6.2 versus 13.3 ± 9.5 days; P = 0.036) were significantly lower in the sivelestat group. The hospital mortality rate decreased by half in the sivelestat group, but was not significantly different between the two groups.Conclusion: Administration of sivelestat to patients with ALI/ARDS following surgery for abdominal sepsis resulted in early improvements of oxygenation and multiple organ dysfunction score, early ventilator weaning, and early discharge from the intensive care unit.Keywords: sivelestat, acute lung injury, acute respiratory distress syndrome, abdominal sepsis
