A flow feature detection method for modeling pressure distribution around a cylinder in non-uniform flows by using a convolutional neural network
Authors: Ye Shuran , Zhang Zhen , Song Xudong , Wang Yiwei , Chen Yaosong , Huang Chenguang
Published: March 2020

In a myriad of engineering situations, we often hope to establish a model which can acquire load conditions around structures through flow features detection. A data-driven method is developed to predict the pressure on a cylinder from velocity distributions in its wake flow. The proposed deep learning neural network is constituted with convolutional layers and fully–connected layers: The convolutional layers can process the velocity information by features extraction, which are gathered by the fully-connected layers to obtain the pressure coefficients. By comparing the output data of the typical network with Computational Fluid Dynamics (CFD) results as reference values, it suggests that the present convolutional neural network (CNN) is able to predict the pressure coefficient in the vicinity of the trained Reynolds numbers with various inlet flow profiles and achieves a high overall precision. Moreover, a transfer learning approach is adopted to preserve the feature detection ability by keeping the parameters in the convolutional layers unchanged while shifting parameters in the fully-connected layers. Further results show that this transfer learning network has nearly the same precision while significantly lower cost. The active prospects of convolutional neural network in fluid mechanics have also been demonstrated, which can inspire more kinds of loads prediction in the future.
Hypergravity induced disruption of cerebellar motor coordination
Authors: Noh Wonjun , Lee Minseok , Kim Hyun Ji , Kim Kyu-Sung , Yang Sunggu
Published: March 2020

The cerebellum coordinates voluntary movements for balanced motor activity in a normal gravity condition. It remains unknown how hypergravity is associated with cerebellum-dependent motor behaviors and Purkinje cell’s activities. In order to investigate the relationship between gravity and cerebellar physiology, we measured AMPA-mediated fast currents and mGluR1-mediated slow currents of cerebellar Purkinje cells along with cerebellum-dependent behaviors such as the footprint and irregular ladder under a hypergravity condition. We found abnormal animal behaviors in the footprint and irregular ladder tests under hypergravity. They are correlated with decreased AMPA and mGluR1-mediated synaptic currents of Purkinje cells. These results indicate that gravity regulates the activity of Purkinje cells, thereby modulating cerebellum-dependent motor outputs.
First-Principles Predictions and Synthesis of B50C2 by Chemical Vapor Deposition
Authors: Baker Paul A. , Chen Wei-Chih , Chen Cheng-Chien , Catledge Shane A. , Vohra Yogesh K.
Published: March 2020

Density functional theory predictions have been combined with the microwave-plasma chemical vapor deposition technique to explore metastable synthesis of boron-rich boron-carbide materials. A thin film synthesis of high-hardness (up to 37 GPa) B50C2 via chemical vapor deposition was achieved. Characterization of the experimental crystal structure matches well with a new theoretical model structure, with carbon atoms inserted into the boron icosahedra and 2b sites in a α-tetragonal B52 base structure. Previously reported metallic B50C2 structures with carbons inserted only into the 2b or 4c sites are found to be dynamically unstable. The newly predicted structure is insulating and dynamically stable, with a computed hardness value and electrical properties in excellent agreement with the experiment. The present study thus validates the density functional theory calculations of stable crystal structures in boron-rich boron-carbide system and provides a pathway for large-area synthesis of novel materials by the chemical vapor deposition method.

Published: March 2020

Xanthine oxidoreductase (XOR) inhibitor administration reduces uric acid and reactive oxygen species (ROS) production, and also lowers blood pressure (BP). However, the associations of plasma XOR activity, uric acid level, and oxidative stress levels with BP remain unclear. This cross-sectional study included 156 subjects (68 males, 88 females) registered in the MedCity21 health examination registry without anti-hypertensive or anti-hyperuricemic agent administration. Plasma XOR activity was measured using our highly sensitive novel assay, which is unaffected by uric acid in the sample. BP was also determined, and serum uric acid and derivative of reactive oxygen metabolites (d-ROMs) levels were simultaneously measured. Median plasma XOR activity, serum uric acid, d-ROMs, and mean arterial pressure (MAP) values were 25.7 pmol/h/mL, 5.4 mg/dL, 305 Carr U, and 89.0 mmHg, respectively. Multiple regression analysis showed that plasma XOR activity (β = 0.211, p = 0.019), but not serum uric acid (β = 0.072, p = 0.502), was significantly associated with MAP. In subjects with lower but not higher d-ROMs level, an independent association of plasma XOR activity with MAP was observed (β = 0.428, p = 0.001 and β = 0.019, p = 0.891, respectively; p for interaction = 0.046). XOR may contribute to the pathophysiology of higher BP through ROS but not uric acid production, especially in patients with lower oxidative stress.

Research on evolution of collaboration mechanism of stakeholders in mining enterprises’ implementation of social responsibility
Authors: Nie Xingxin , Zhang Jingjing , Yang Luhan
Published: March 2020

Multiple stakeholders are involved when mining enterprises assume their social responsibility, so a tripartite game pattern among local government, mining enterprises and local community is formed after supervision is introduced. By combining evolutionary game model with system dynamics for simulation analysis, this paper studies the dynamic game process among the three parties and we find out that: (1) local government, mining enterprises and local community will eventually reach a stable equilibrium state (supervision, participation, performance), and it will simplify the evolutionary path of the stable equilibrium state when local government chooses supervision at the early stage; (2) local government plays a leading role in supervision, and the strategy choices of mining enterprises and local community depend on local government’s strategy and the relationship between the size of exogenous; (3) the formation of the eventual stabilization strategy is decided by the joint action of multiple variables, although every single variable will affect the strategy choice of all parties, so local government should deal with the relationship between various stakeholders properly.
Implementation of a Blood-Saving Program in a Pediatric Intensive
Care Unit to Reduce Diagnostic Blood Loss
Authors: Michel Jörg , Hofbeck Michael , Balcells Judit Vinuales , Kumpf Matthias , Neunhoeffer Felix
Published: March 2020

Background We aimed to reduce blood loss in the pediatric critical care
unit (PICU) due to blood sampling in neonates and infants. Therefore, an
educational program for our staff was established and evaluated.

Methods Patients in a PICU of a tertiary referral center aged
0–12 months who underwent surgery of congenital heart disease on
cardiopulmonary bypass were enrolled and divided into a pre- and a
post-implementation group. We assessed frequency and types of postoperative
blood samples, required blood volume, and amount of blood transfusions in the
PICU within 5 days after cardiac surgery.

Results Populations were similar prior and after the implementation.
Blood drawn for blood gas analysis (0,52 ml±0,16 vs.
0,38 ml±0,12, p<0,001) and for complete blood sampling
(2,62 ml±0,32 vs. 2,11 ml±0,35, p<0,001)
could be successfully reduced after implementation of our blood-saving program.
The daily diagnostic blood loss per patient was significantly reduced by
approximately 35% (1,7 ml/kg/d±1,0 vs.
1,1 ml/kg/d±0,7, p=0,008).

Discussion Our quality improvement program is feasible and effective to
significantly reduce the blood loss due to blood sampling. Although the
incidence of red blood cell transfusions was not significantly reduced, it is
certainly beneficial to try to reduce diagnostic blood loss, especially in
children with complex diseases requiring long-term intensive care treatment.

Conclusion We could demonstrate that it is possible to significantly
reduce the blood loss due to blood sampling with a simple educational program
for PICU staff.
Traumatic Brain Injury in Young Children: A Scoping Review
Authors: Salley Jessica , Crook Libby , Ciccia Angela , Haarbauer-Krupa Juliet , Lundine Jennifer P.
Published: March 2020

To review the evidence available on early childhood (i.e., 0–5 years 11 months) traumatic brain injury (TBI) and identify clinical implications and future directions for speech-language pathology (SLP) practice and research, a scoping review of the literature was conducted following the 2018 Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRSIMA-ScR) guidelines. A total of 44 peer-reviewed articles were included for review. Included studies were assigned one or more of the following thematic labels related to early childhood TBI: etiology, assessment, treatment, outcomes, contributing factors. Most of the studies were nonexperimental studies and addressed outcomes following early childhood TBI. We conclude, based on this scoping review, that children who experience a TBI before 6 years of age are at risk for persistent long-term difficulties in academic and social functioning. SLPs are among the group of clinicians most appropriate to assess and treat these children; yet, the evidence for assessment, treatment, and identification of factors contributing to the recovery of young children with TBI is particularly lacking. Rigorous research is needed to improve the evidence base for SLPs.
Gene editing and gender-specific medicine: a challenge for dementia research
Authors: Zullo Silvia , Caenazzo Luciana
Published: March 2020

Gender-specific medicine is a clinical discipline that studies the impact of sex and gender on physiology, pathophysiology, and diseases. Human genome modification of somatic cells could be useful for treating or preventing a range of diseases and for improving the safety and efficiency of existing gene therapy techniques currently in use or under development for clinical application. Sex and gender differences have been analysed in the incidence and prevalence of dementia. In fact, epidemiological studies have demonstrated that women are at a higher risk than men for developing dementia or Alzheimer’s disease (AD); however, the reasons for these differences are not completely known, and the debate is still underway. In recent years, in the effort to clarify the risk of developing dementia or AD, increasing attention has been devoted to the differences between men and women in the causes and manifestations of neurological diseases, as well as to their response to treatment and to outcomes. Through a conceptual analysis we will argue that an emphasis on gender-specific medicine in gene-editing research can contribute to the progress of medicine by introducing a relevant value-driven perspective on health and diseases. This is something we will do on the basis of a gender-specific strategy. In fact, focusing on the effect of sex on dementias and in particular AD may be essential in advancing our understanding, treatment and prevention of these disorders, considering that AD and other dementias disproportionately affect women, and it underlined the relevance of empirical data relating to sex differences and emerging sex-specific findings in dementias in order to assess the scientific approach to these diseases for the improvement of quality of life for both women and men. It may be helpful and suitable to consider how the interventions that modify the genome should include sex and gender as a crucially important variable accounting for the differences between men and women in the causes and manifestations of diseases, as well as in the response to treatment and to outcomes. Of course, gene editing cannot remove biological differences, but its potential harmful effects, on one group relative to another, can be prevented with a research strategy that properly takes them into account with a view to equity between genders.

Here, we describe a general-purpose prediction model. Our approach requires three matrices of equal size and uses two equations to determine the behavior against two possible outcomes. We use an example based on photon-pixel coupling data to show that in humans, this solution can indicate the predisposition to disease. An implementation of this model is made available in the supplementary material.
Charge transport and dynamic response of organic and polymer transistors
Authors: Krutko Oleksiy , Dodabalapur Ananth
Published: March 2020

It is shown that the dynamic response of a thin-film transistor (TFT) comprises a polymer or organic semiconductor and can be directly correlated with charge transport parameters. Charge transport is assumed to take place in accordance with the often employed multiple trap and release model. We can simulate the non-quasistatic response of TFTs for devices in which the mobility is not constant, but depends on carrier density and other parameters. The previous model of Burns has been significantly improved and made applicable to organic and polymer transistors. Our approach works for an arbitrary density of states including both a relatively shallow exponential distribution of tail states and deeper Gaussian trap states. We set the gate voltage, VG, in our TFTs to be zero. The source voltage, VS, is varied and, thus, the value of gate-to-source voltage is varied. The predictive power of the model that is presented in this paper will be very useful for accurate device modeling and for charge transport studies.

Z-pinch experiments with a hybrid configuration of a deuterium gas puff have been carried out on the HAWK (NRL, Washington, DC) and GIT-12 (IHCE, Tomsk) pulsed power generators at 0.7 MA and 3 MA currents, respectively. On GIT-12, neutron yields reached an average value of 2 × 1012 neutrons, and deuterons were accelerated up to an energy of 30 MeV. This was 50 times the ion energy provided by the generator driving voltage of 0.6 MV and the highest energy observed in z-pinches and dense plasma foci. To confirm these unique results independently on another device, we performed several experimental campaigns on the HAWK generator. Comparison of the experiments on GIT-12 and HAWK helped us to understand which parameters are essential for optimized neutron production. Since the HAWK generator is of a similar pulsed power architecture as GIT-12, the experiments on GIT-12 and HAWK are important for the study of how charged-particle acceleration scales with the current.
Full waveform analysis for high pressure ultrasonic measurement
Authors: Li L. , Weidner D. J.
Published: March 2020

We report a data analysis protocol for ultrasonic velocity measurements carried out in a synchrotron x-ray facility based multi-anvil high-pressure apparatus. Synthetic ultrasonic signals for the time period between echoes from the two ends of the sample assembly are created with a few simple parameters as the echo waveform is modeled by the first echo from the anvil-assembly boundary. Each echo is modeled as a delta function with an amplitude and arrival time and convolved with this waveform. The final waveform, fit to the data, enables analysis of signals with overlapped echoes as they are common in small cell assemblies and high pressure.

Published: March 2020

This article deals with the extension of the relativistic double-ionization equation-of-motion coupled-cluster (DI-EOMCC) method [H. Pathak et al. Phys. Rev. A 90, 010501(R) (2014)] for the molecular systems. The Dirac–Coulomb Hamiltonian with four-component spinors is considered to take care of the relativistic effects. The implemented method is employed to compute a few low-lying doubly ionized states of noble gas atoms (Ar, Kr, Xe, and Rn) and Cl2, Br2, HBr, and HI. Additionally, we presented results with two intermediate schemes in the four-component relativistic DI-EOMCC framework to understand the role of electron correlation. The computed double ionization spectra for the atomic systems are compared with the values from the non-relativistic DI-EOMCC method with spin–orbit coupling [Z. Wang et al. J. Chem. Phys. 142, 144109 (2015)] and the values from the National Institute of Science and Technology (NIST) database. Our atomic results are found to be in good agreement with the NIST values. Furthermore, the obtained results for the molecular systems agree well with the available experimental values.

Published: March 2020

We demonstrate a novel approach to the generation of femtosecond electron bunch trains via laser-driven wakefield acceleration. We use two independent high-intensity laser pulses, a drive, and an injector, each creating their own plasma wakes. The interaction of the laser pulses and their wakes results in a periodic injection of free electrons in the drive plasma wake via several mechanisms, including ponderomotive drift, wake-wake interference, and pre-acceleration of electrons directly by strong laser fields. Electron trains were generated with up to four quasi-monoenergetic bunches, each separated in time by a plasma period. The time profile of the generated trains is deduced from an analysis of beam loading and confirmed using 2D particle-in-cell simulations.
Thickness-dependent electron momentum relaxation times in iron films

Published: March 2020

Terahertz time-domain conductivity measurements in 2–100 nm thick iron films resolve the femtosecond time delay between the applied electric fields and the resulting currents. This current response time decreases from 29 fs for the thickest films to 7 fs for the thinnest films. The macroscopic response time is not strictly proportional to the conductivity. This excludes the existence of a single relaxation time universal for all conduction electrons. We must assume a distribution of microscopic momentum relaxation times. The macroscopic response time depends on the average and variation of this distribution; the observed deviation between the response time and conductivity scaling corresponds to the scaling of the variation. The variation of microscopic relaxation times depends on the film thickness because electrons with different relaxation times are affected differently by the confinement since they have different mean free paths.
Experimental study on secondary flow in turbulent boundary layer over spanwise heterogeneous microgrooves
Authors: Xu Fang , Zhong Shan , Zhang Shanying
Published: March 2020

Convergent–divergent riblets (C–D riblets) are a type of grooved surface pattern with directionality and spanwise heterogeneity. In the cross-stream plane, we apply stereoscopic particle image velocimetry to study the characteristics of the secondary flow over C–D riblets. Three different heights of h+ = 8, 14, and 20 are applied in the turbulent boundary layers at Reθ = 723 to reveal the effect of riblet height on the flow field. In the cross-stream plane, increasing the riblet height intensifies the heterogeneity of turbulent properties, i.e., a wider downwelling region, a stronger spanwise flow, a narrower upwelling region, and a stronger deceleration effect. Compared with the smooth-wall case, the magnitude of spanwise velocity fluctuations is larger over the converging region. The dispersive momentum transfer is primarily contributed by the secondary-flow-induced stress compared with the roughness-induced stress, and it becomes more intense as the riblet height increases. Compared with the smooth-wall case, the near-wall streamwise turbulent events are slightly wider over the diverging region and much narrower over the converging region. Overall, the higher C–D riblets generate a more intense secondary flow, and the mechanism of an increasing riblet height is attributed to the greater capability of deeper yawed microgrooves. In light of the results from our study, we propose a different way of categorizing the surface patterns with spanwise heterogeneity from the perspectives of surface geometry, roll mode, and secondary flow generation mechanisms.

The pulsation of cavitation bubbles under constraint conditions has complex dynamic characteristics and has been widely applied in various fields, such as liquid pumping, underwater propulsion, and clinical applications. In this study, the dynamic behaviors of a laser-induced bubble in a tube are investigated under different initial conditions. A high-speed optical visualization is carried out in the experiments. The numerical simulation based on the volume-of-fluid method is implemented on the open source code OpenFOAM. From the experimental observation and numerical analysis, an axial jet pointing toward the front end of the tube is generated during bubble shrinkage. According to the type of the axial jet, the collapse patterns are classified into three regimes: one-dimensional, transitional, and three-dimensional. Furthermore, it is also found that the normalized initial energy of the bubble and the length-to-diameter ratio affect the maximum length and the pulsation period of the bubble. Finally, the transition mechanism of the collapse patterns from one dimension to three dimension is obtained through a phase diagram by combining experimental observations with numerical simulation.

Tuning the structure of organic–inorganic perovskites by pressure holds great promise for discovering materials with favorable properties. However, most of their high-pressure structures cannot be preserved at ambient conditions and little is known about how to control the properties of these materials recovered from high pressure. Here, we have manipulated the bandgap in a high-pressure-treated 2D organic-inorganic halide perovskite. We find that the bandgap of this compound can be largely altered by pressure-induced lattice disorder. Below 25 GPa, the phase transition is reversible and the thus-produced lattice distortion cannot be preserved after pressure release. In contrast, for the sample treated above 25 GPa, the structural disorder can be preserved at ambient pressure. Consequently, the bandgap of the sample can be profoundly tuned from 2.98 to 3.46 eV. These findings offer an extraordinary example for manipulating the structure and electronic properties of organic–inorganic perovskites by high pressure treatment.
On the shear dilation of polycrystalline lubricant films in boundary lubricated contacts

Published: March 2020

Shearing of a solidified polycrystalline lubricant film confined between two solid surfaces has been studied by molecular dynamics simulations. In the case of a perfect commensurate contact, we observe interlayer slips within the film and shear-induced order-to-disorder transition of lubricant molecules around grain boundaries. This process is accompanied by the nucleation, propagation, and annihilation of dislocations in the solidified film, resulting in repeated dilation and collapse of the lubricant film during the stick–slip motion. In the case of an incommensurate contact, only slips at the lubricant–solid interface happen and no dilation of the lubricant film is observed during the stick–slip friction. These observations are consistent with recent surface force balance experimental measurements. In combination with our recent work [R. G. Xu and Y. S. Leng, Proc. Natl. Acad. Sci. U. S. A. 115, 6560 (2018)], this study provides a renewed picture on the physical property of nanoconfined lubricant films in boundary lubrication.
