Authors: Yarahuan Julia K.W. , Lo Huay-Ying , Bass Lanessa , Wright Jeff , Hess Lauren M. 
Published: June 2022

Abstract
Background and Objectives Pediatric residency programs are required by the Accreditation Council for Graduate Medical Education to provide residents with patient-care and quality metrics to facilitate self-identification of knowledge gaps to prioritize improvement efforts. Trainees are interested in receiving this data, but this is a largely unmet need. Our objectives were to (1) design and implement an automated dashboard providing individualized data to residents, and (2) examine the usability and acceptability of the dashboard among pediatric residents.
Methods We developed a dashboard containing individualized patient-care data for pediatric residents with emphasis on needs identified by residents and residency leadership. To build the dashboard, we created a connection from a clinical data warehouse to data visualization software. We allocated patients to residents based on note authorship and created individualized reports with masked identities that preserved anonymity. After development, we conducted usability and acceptability testing with 11 resident users utilizing a mixed-methods approach. We conducted interviews and anonymous surveys which evaluated technical features of the application, ease of use, as well as users' attitudes toward using the dashboard. Categories and subcategories from usability interviews were identified using a content analysis approach.
Results Our dashboard provides individualized metrics including diagnosis exposure counts, procedure counts, efficiency metrics, and quality metrics. In content analysis of the usability testing interviews, the most frequently mentioned use of the dashboard was to aid a resident's self-directed learning. Residents had few concerns about the dashboard overall. Surveyed residents found the dashboard easy to use and expressed intention to use the dashboard in the future.
Conclusion Automated dashboards may be a solution to the current challenge of providing trainees with individualized patient-care data. Our usability testing revealed that residents found our dashboard to be useful and that they intended to use this tool to facilitate development of self-directed learning plans.

Published: June 2022

A novel trigger generator for operating a pseudospark switch has been developed based on a modified modular multilevel converter topology using insulated gate bipolar transistors. The trigger generator can be operated in either single- or high-repetition rate shot mode. It is characterized by a fast rise time and low temporal jitter between the output trigger pulses of less than 1 ns. It produces pulses of 4.5 kV and 1 µs duration into a 50 Ω load that can trigger a single pseudospark switch. By minimizing the high-voltage components, faster high-voltage switching takes place and the power density of the unit is increased. Furthermore, the overall volume of the trigger generator is reduced. Using this pseudospark trigger generator, it is possible to trigger single or multiple pseudospark gaps without the requirement to use a pulse shaping circuit.

Published: June 2022

Abstract
Energy transformation, which can be described as temperature variations, is present in all activities of cellular metabolism. Detecting the temperature of numerous cells over the course of their lives is useful for studying the cellular physiological function and investigating the pathophysiology of illnesses. Current cell thermometric technologies, such as luminous temperature sensors, infrared thermometers, and thermocouple thermometers, have their own limitations, such as complicated operation, low repeatability, and inability to measure cell temperature in normal situations. Here, we have developed a high-precision platinum temperature sensor with small heat capacity, good heat conduction, excellent stability and biological compatibility, which made it possible to sense cells heat signal. The platinum resistance sensor’s temperature coefficient of resistance was around 2800 ppm °C−1, with a good linear correlation (R
2 > 0.999) between resistance and temperature from 35 °C to 43 °C. The noise of the sensor system was below 0.02 °C, giving a small and stability noise in detection. The detecting cells were CHO-K1 cells. They caused a temperature increase of about 0.075 °C, which is higher than the sensor without cells. This platinum sensor has been found to be useful for in situ temperature measurement of cells, which is important for investigating cell informatics and pathology.

Published: June 2022

Abstract
Thermophotovoltaic (TPV) systems consume near infrared (NIR) filters, which are key components for high conversion efficiency. Bandpass filters employing annular aperture array (AAA) on a fused silica substrate are one of candidates for matching GaSb cells in high-temperature TPV. It is often placed independently between the emitter and cell, and thus spectral control and heat insulation are simultaneously realized. For high efficiency, the smaller the characteristic size and the larger the size is beneficial for the filter. Novel sidewall lithography based on conventional interference lithography and ion-beam etching is first proposed and used for cost-effective fabrication. An AAA filter with a 80 nm critical dimension in a 100 mm × 160 mm area has been fabricated successfully. After the annealing process at 500 °C, the peak transmittance is increased to 70% from 65%, and no deformation is observed in the structural parameters of the filter before and after annealing, and calculated results demonstrate that the spectral efficiency is about 61%.
Phase diagram of chiral magnets via Green’s function method
Authors: Li Xi-Bin , Cao Yongjun , Bai Narsu 
Published: June 2022

Abstract
In this paper, Green’s function method is applied to study the ferromagnetic system with Dzyaloshinkii–Moriya (DM) interaction in both two-dimension (2D) and three-dimension chiral magnets. Relevant properties in 2D magnets are calculated, such as the susceptibility, correlation function and analytical expressions of phase boundary. Based on the theoretical results, a new phase is predicted in the window of strong DM interaction characterized by a negative winding number. In addition, helical state in pure 2D material only appears at zero temperature. The analysis on correlation function shows a special symmetry of transverse spin correlation, which corresponds to the skyrmion phase. The results also prove the instability of helical state and its lifetime is numerically computed. Different from 2D magnets, helical state in 3D exists in the window of a lower Zeeman energy and has a long lifetime. DM interaction also reduces Curie temperature because of the spatial symmetry breaking.

Abstract
The initial health impact caused by radiation disasters can be broadly classified into direct and indirect effects. Though no direct health hazards caused by radiation, such as acute radiation injury, were observed following the Fukushima Daiichi nuclear power plant accident, indirect deaths have been reported, including those caused by initial emergency evacuation and relocation, medical disruption, and psychological and social health effects. However, these indirect health effects have not been prioritised for addressal. We evaluated the radiation disaster experience with that of the coronavirus disease (COVID-19) pandemic that emerged while facing the challenges from the radiation disaster. Most of the health effects of COVID-19 are directly associated with infection, but indirect health effects of various scales and entities have been reported. The two disasters have similarities in terms of the strain on community healthcare and the large number of deaths. Adapting the measures implemented in the acute to subacute phases of the COVID-19 disaster to radiation disasters may help improve management following future radiation disasters. Based on the experience and findings during the COVID-19 pandemic, the pattern of deaths in radiation disasters can be divided into five major groups: direct deaths, and four indirect patterns of deaths due to a deteriorating supply-demand balance (a hospital-level problem), collapse of the healthcare system (a community-level problem), death due to neglect alongside underlying disease, and diseases other than direct invasion. From the similarities between the two disasters, three main issues should be prioritised as initial emergency evacuation measures in a radiation disaster: emergency exposure medicine, the establishment of a medical system, and protection of death with dignity. The validity of these priority issues needs to be verified in future research.
Time-resolved multi-parameter flow diagnostics by filtered Rayleigh scattering: system design through multi-objective optimisation
Authors: Doll Ulrich , Röhle Ingo , Dues Michael , Kapulla Ralf 
Published: June 2022

Abstract
The measurement of the time-resolved three-component (3C) velocity field together with scalar flow quantities such as temperature or pressure by laser-optical diagnostics is a challenging task. Current approaches usually employ combinations of different methods relying on tracer particles or molecules. This typically requires usage of at least two laser systems and detection units as well as elaborate calibration of the luminous properties of the applied tracer species with regard to the specific thermodynamic conditions anticipated for the flow case at hand. In contrast to this, the tracer-free filtered Rayleigh scattering (FRS) technique has been proven to obtain combined time-averaged velocity and scalar fields and might offer a viable alternative for unsteady flow diagnostics. By applying multiple perspective views, two detection system variants are presented, combining (1) six observation branches with one camera/molecular filter and (2) three camera views with two cameras and molecular filters of differing vapour densities. Both configurations in principle allow for the simultaneous measurement of instantaneous 3C velocity, temperature and pressure fields. Multi-objective optimisation is used to enhance the detection setups for different sets of experimental configurations. It is shown that a higher number of observation positions and the associated dynamics of the FRS signal prove to be advantageous compared to the use of less views in combination with two acquisition channels equipped with different molecular filters. It is also shown that the use of circularly polarised laser light offers no advantage over linear polarisation. By demonstrating a moderate sensitivity of the optimised observation arrangement to alignment errors, the presented FRS concept provides a practical solution for the simultaneous measurement of time-resolved 3C flow velocity and scalar fields.
Time-scale investigation with the modified phase field crystal method
Authors: Burns Duncan , Provatas Nikolas , Grant Martin 
Published: June 2022

Abstract
This paper extends the two time-scale modified phase-field crystal model to examine crystal plasticity. Two non-linear density dependent functions are constructed to effectively represent hydrostatic strain and dislocation density. The functions are then used to develop a new modified phase field crystal model, which accounts for strain and strain-rate couplings on density dynamics. The non-linear additions provide tunable parameters for controlling dislocation climb versus glide, as well as phonon softening mechanisms. A short-wavelength dampening is also introduced to account for phonon scattering and thermoelastic dissipation processes. Finally, a novel semi-implicit numeric scheme for efficient simulations of this model is presented, which also serves as a generalization of the commonly used Fourier pseudo-spectral method. The technique gives rise to unconditionally stable dynamics with simple numeric implementation requirements.
Variations of tunnelling resistance between CNTs with strain in composites: non-monotonicty and influencing factors
Authors: Wang Tengrui , Liu Yongzhi , Liu Hu , Liu Chuntai 
Published: June 2022

Abstract
The electro-mechanical response of conductive carbon-nanotube(CNT)-polymer composites is vital when they are used as smart-sensing materials. Clarifying the variation trend of resistance with strain is the key to design and regulate the piezoresistive property of such material. Here, we present some finite element simulations to predict the electro-mechanical response using a geometrical model comprising two hollow cylindrical CNTs and a cuboid matrix. The electrical contact between CNTs is represented by some elements which account for quantum tunnelling effects and capture the sensitivity of conductivity to separation. Different from classical simulations using solid model or one-dimensional beam model, in which the tunnelling resistance between two CNTs changes monotonously with strain, the results in this work show that the trend is non-monotonic in some cases, i.e. it increases at first and then decreases with the uniaxial compressive strain when the elastic modulus of the matrix is high. In addition, factors affecting the different variation trends are discussed in details, which include geometric model, elastic modulus and Poisson’s ratio of the matrix, and orientation angle.

as h → ∞ have been proved in previous work by Chiricotto and Giacomelli (2011 Commun. Appl. Ind. Math.
2 e-388, 16). We are interested in the asymptotics as h ↓ 0 and h → ∞. By reformulating the problem as h ↓ 0 as a dynamical system for the difference between the solution and the microscopic contact angle, values for n are found for which linear as well as nonlinear resonances occur. These resonances lead to a different asymptotic behavior of the solution as h ↓ 0 depending on n. Together with the asymptotics as h → ∞ characterizing the Cox–Voinov law for the velocity-dependent macroscopic contact angle as found by Giacomelli, the first author of this work, and Otto (2016 Nonlinearity
29 2497–536), the rigorous asymptotics of traveling-wave solutions to the thin-film equation in partial wetting can be characterized. Furthermore, our approach enables us to analyze the relation between the microscopic and macroscopic contact angle. It is found that the Cox–Voinov law for the macroscopic contact angle depends continuously differentiably on the microscopic contact angle.

Published: June 2022

Abstract
Metal halide perovskites are widely used in optoelectronic devices, including solar cells, photodetectors, and light-emitting diodes. Defects in this class of low-temperature solution-processed semiconductors play significant roles in the optoelectronic properties and performance of devices based on these semiconductors. Investigating the defect properties provides not only insight into the origin of the outstanding performance of perovskite optoelectronic devices but also guidance for further improvement of performance. Defects in perovskites have been intensely studied. Here, we review the progress in defect-related physics and techniques for perovskites. We survey the theoretical and computational results of the origin and properties of defects in perovskites. The underlying mechanisms, functions, advantages, and limitations of trap state characterization techniques are discussed. We introduce the effect of defects on the performance of perovskite optoelectronic devices, followed by a discussion of the mechanism of defect treatment. Finally, we summarize and present key challenges and opportunities of defects and their role in the further development of perovskite optoelectronic devices.
Spin dynamics, critical scattering and magnetoelectric coupling mechanism of Mn4Nb2O9
Authors: Deng Guochu , Zhao Gang , Zhu Shuang , Feng Zhenjie , Ren Wei , Cao Shixun , Studer Andrew , McIntyre Garry J 
Published: June 2022

Abstract
The spin dynamics of Mn4Nb2O9 were studied using inelastic neutron scattering. A dynamic model is proposed to explain the observed spin-wave excitation spectrum from Mn4Nb2O9. The model indicates that the exchange interactions along the chain direction are weakly ferromagnetic while the exchange interactions between the neighbour chains are strongly antiferromagnetic. The antiferromagnetic interactions on the two MnO6 octahedron networks are dominant in the spin dynamics of this compound. A spin gap of about 1.4 meV was observed at the zone centre, which is attributed to the weak easy-axis magnetic anisotropy of Mn2+ ions. Magnetic critical scattering from Mn4Nb2O9 was studied in the vicinity of its Néel temperature T
N as well, indicating homogeneous development of magnetic correlations. According to the symmetry analysis and its magnetic structure, the weak magnetoelectric coupling effect in Mn4Nb2O9 is ascribed to the uncancelled exchange striction on the two non-equivalent Mn2+ sites.

Published: June 2022

Abstract
We use a large sample of gamma-ray narrow-line Seyfert 1 galaxies (γ-NLS1s) to study the jet formation mechanisms. We find that the jet power of γ-NLS1s is lower than the maximum jet power of the Blandford–Payne (BP) mechanism. At the same time, we find that there is a significant correlation between jet power and accretion disk luminosity. Moreover, the contribution rates of the accretion to the jet power are larger than that of black hole mass to jet power. These results further suggest that the jet of γ NLS1s is mainly produced by the BP mechanism.

Published: June 2022

Abstract
In this work, the capillary pressure curves were approximated using fractions of various types for the conditions of individual oil deposits of the West Siberian oil and gas province. A mathematical model of capillary curves in the coordinate axes of dimensionless time from the normalized water saturation has been created. The obtained models make it possible to search for analog objects and effectively solve the problems of increasing the efficiency of developing low-profitable deposits with hard-to-recover reserves based on comparing the regression equations of generalized models with models of the required deposits.
Developing “friend or foe” protocol in residue number system code for satellite authentication

Published: June 2022

Abstract
Low-earth orbit (LEO) satellite communication systems are successfully used in control and monitoring systems for the production and transportation of hydrocarbons from fields located beyond the Arctic Circle. As the number of countries engaged in the development of such fields expands, the number of groupings of LEO satellite communication systems grows as well. To prevent the possibility of intercepting and imposing a delayed command to control the intruder satellite, it is necessary to use the “friend or foe” identification system for the LEO satellite communication systems. At the same time, it is proposed to use authentication protocols with zero knowledge to ensure high imitation resistance in such systems. To increase their efficiency, the article proposes to use the codes of the residual number system (RNS). The novelty of this idea lies in the fact that the use of parallel RNS codes will reduce the time spent on performing arithmetic operations implemented in authentication protocols. This will reduce the likelihood of an intruder satellite picking up the correct response signal. Therefore, the development of an authentication protocol for LEO satellite communication systems based on RNS codes, the use of which will reduce the time for satellite identification, is an urgent task.
