Risk assessment of coal mine water inrush based on PCA-DBN
Authors: Zhang Ye , Tang Shoufeng , Shi Ke 
Published: January 2022

AbstractTo provide an effective risk assessment of water inrush for coal mine safety production, a BP neural network prediction method for water inrush based on principal component analysis and deep confidence network optimization was proposed. Because deep belief network (DBN) is disadvantaged by a long training time when establishing a high-dimensional data classification model, the principal component analysis (PCA) method is used to reduce the dimensionality of many factors affecting the water inrush of the coal seam floor, thus reducing the number of variables of the research object, redundancy and the difficulty of feature extraction and shortening the training time of the model. Then, a DBN network was used to extract secondary features from the processed nonlinear data, and a more abstract high-level representation was formed by combining low-level features to find the expression of the nonlinear relationship between the characteristics of water in bursts. Finally, a prediction model was established to predict the water inrush in coal mines. The superiority of this method was verified by comparing the prediction of the actual working face with the actual situation in typical mining areas of North China. The prediction accuracy of coal mine water inrush obtained by this algorithm is 94%, while the prediction accuracy of traditional BP algorithm is 70%, and the prediction accuracy of SVM algorithm is 88%.
Relaxation of stationary states on a quantum computer yields a unique spectroscopic fingerprint of the computer’s noise

Published: January 2022

AbstractQuantum computing has the potential to revolutionize computing, but its significant sensitivity to noise requires sophisticated error correction and mitigation. Traditionally, noise on the quantum device is characterized directly through qubit and gate measurements, but this approach has drawbacks in that it does not adequately capture the effect of noise on realistic multi-qubit applications. In this paper, we simulate the relaxation of stationary quantum states on a quantum computer to obtain a unique spectroscopic fingerprint of the computer’s noise. In contrast to traditional approaches, we obtain the frequency profile of the noise as it is experienced by the simulated stationary quantum states. Data from multiple superconducting-qubit IBM processors show that noise generates a bath within the simulation that exhibits both colored noise and non-Markovian behavior. Our results provide a direction for noise mitigation but also suggest how to use noise for quantum simulations of open systems.

Published: January 2022

AbstractHere, a multi‐band microstrip‐fed antenna is presented. The compact size of the antenna is 32 × 18 mm2, which makes it attractive to mobile devices. Antenna prototype is fabricated using FR4 dielectric material with dielectric constant 4.4 and thickness 1.6 mm. The radiating patch of the antenna consists of four hook‐shaped rings and truncated ground‐plane helps to achieve good impedance matching. A very compact microstrip feedline is utilized to couple electromagnetic energy to radiating patch. The measured S11 ≤ ‐10 dB of the multiband antenna is achieved at the GSM 1800 /1900 MHz, Bluetooth 2.4 GHz, WLAN 2.4/5.2 GHz and WiMAX 2.5/3.5/5.5 GHz bands. The antenna's performance reveals that it operates in several bands, has a high gain, and radiates in an omnidirectional pattern. Simulated and measured results are presented to show good accommodation. In addition, to have a good view and better show the innovation presented in this article, the suggested multi‐band monopole antenna is compared to various previously presented multiband microstrip antennas using the Analytic Hierarchy Process approach which is an accurate and fair method for selecting the best candidate and is used a lot in various cases.

Published: January 2022

AbstractHere, the DC side passive harmonic reduction circuits (PHRCs) are compared from a technical and economic point of view. In researches on multipulse rectifiers (MPRs), the comparison is mainly based on different source and load conditions, especially accurate information on the amount of the source impedance is not available, which has a considerable impact on the performance of MPRs. Here, all source conditions such as voltage, frequency, and the source impedance, as well as the load power are set to be the same, in order to have an accurate and fair comparison among PHRCs at the DC side of MPRs. Some commonly‐used and several DC side PHRCs are compared in terms of their operation principles, kVA rating, weight and size, power losses, input current total harmonic distortion (THD), design complexity, reliability, and cost. The results of the comparisons are used to suggest and select the most suitable PHRCs for different important industrial applications.
Entropy of pure states: not all wave functions are born equal
Authors: Sunko Denis K. 
Published: January 2022

Many-body Hilbert space has the algebraic structure of a finitely generated free module. All N-body wave functions in d dimensions can be generated by a finite number of N!d − 1 of generators called shapes, with symmetric-function coefficients. Physically the shapes are vacuum states, while the symmetric coefficients are bosonic excitations of these vacua. It is shown here that logical entropy can be used to distinguish fermion shapes by information content, although they are pure states whose usual quantum entropies are zero. The construction is based on the known algebraic structure of fermion shapes. It is presented for the case of N fermions in three dimensions. The background of this result is presented as an introductory review.

Published: January 2022

AbstractThe Pandora's box has been opened in the twenty-first century unleashing “the Coronavirus.” There has been an increase in the incidence of mucormycosis during this coronavirus disease 2019 (COVID-19) pandemic with many case reports of rhino-orbito-cerebral and pulmonary mucormycosis. Diabetes mellitus, COVID, and Mucor fungus together are a dangerous trio associated with high mortality. We report a rare case of renal mucormycosis following COVID pneumonia in a 64-year-old patient with uncontrolled diabetes; with the imaging findings of left emphysematous pyelonephritis and cystitis, nonfunctioning left kidney, and left main renal artery and vein thrombosis. This is the first such case reported to our knowledge. A high degree of clinical suspicion with prompt recognition of imaging findings is essential to improve the chances of survival in such patients.

Abstract
Background Patients with atrial fibrillation (AF) are frequently treated with apixaban 2.5-mg twice daily (BID) off-label, presumably to reduce the bleeding risk. However, this approach has the potential to increase the risk of ischemic stroke. If a single measurement could reliably identify patients with high drug levels, the increased stroke risk may be mitigated by confining off-label dose reduction to such patients.
Objectives This study aimed to determine whether a single high apixaban level is predictive of a similarly high level when the test is repeated in 2 months.
Methods In this prospective cohort study of clinic patients receiving apixaban 5-mg BID for AF or venous thromboembolism, peak and trough apixaban levels were measured using the STA-Liquid anti-Xa assay at baseline and 2 months. We calculated the proportions of patients with levels that remained in the upper quintile.
Results Of 100 enrolled patients, 82 came for a second visit, 55 of whom were treated with apixaban 5-mg BID. Seven (63.6%, 95% confidence interval [CI]: 35.4–84.8%) and nine (81.8%, 95% CI: 52.3–94.9%) of 11 patients with a baseline trough and peak level in the upper quintile, respectively, had a subsequent level that remained within this range. Only one (9.1%, 95% CI: 1.6–37.7%) patient had a subsequent level that fell just lower than the median.
Conclusion The trough and peak levels of apixaban in patients who have a high level on a single occasion, usually remain high when the assay is repeated in 2 months. Accordingly, the finding of a high apixaban level in patients deemed to be at high risk of bleeding, allows physicians contemplating off-label use of the 2.5-mg BID dose to limit its use to selected patients who are less likely to be exposed to an increased risk of thrombosis.

AbstractPain impairs reward processing, and people suffering from physical pain are at high risk of having a persistently low mood. Although individuals with chronic pain have reported reduced reward responsiveness and impaired mood, it is not clear if reward responsiveness and mood are impaired in samples with sub-clinical pain scores otherwise healthy. Investigating a sub-clinical group is essential to disentangle the influence of medication on the behavioural effect of reward on mood and performance. Here, we aimed to examine the effects of reward on mood and performance in a sample of university students divided into a control group without clinically significant pain symptoms (N = 40) and the sub-clinical group with significant pain symptoms (N = 39). We used the Fribourg reward task and the pain sub-scale of the Symptom Checklist (SCL-27-plus) to assess the physical symptoms of pain. A significant positive correlation was found between average mood ratings and average monetary reward in the control group (r38 = 0.42,p = 0.008) and not significant in the sub-clinical group (r37 = 0.12,p = 0.46). The results might yield first insights into the relationship between pain and reward in sub-clinical populations without the confound of medication.

As the major source of edible protein and oil, the global demand for soybean (Glycine max (L.) Merr.) is increasing. Plant height is closely related to yield; therefore, understanding the genetic basis of plant height will help to improve soybean plant type and increase seed yield. In this study, quantitative trait loci (QTLs) and nucleotides (QTNs) for soybean plant height were detected by linkage analysis and association analysis. A high-density map containing 2225 bin markers was constructed by using 108 342 SNPs of a recombinant inbred line population (named RIL3613) of 120 lines for linkage analysis. In total, 39 QTLs were detected, including 16 QTLs that were repeatedly detected in multiple environments. Association analysis was performed by using 63 306 SNPs from a germplasm population of 455 natural soybean accessions. In total, 62 QTNs were detected, and 26 QTNs were repeatedly detected by multiple methods. Fourteen QTNs were distributed in the intervals of six multiple-environment QTLs by comparing the results of association analysis and linkage analysis. With pathway analysis, six candidate genes were identified as being associated with plant height. These results contribute to analysis of the genetic basis of plant height and will promote marker-assisted selection for breeding ideal plant shape.
Evaluation of the DNDCv.CAN model for simulating greenhouse gas emissions under crop rotations that include winter cover crops
Authors: Singh Jasdeep , Kumar Sandeep 
Published: January 2022

Context Process-based modelling studies can help inform conservation practices for mitigating soil surface CO2 and N2O fluxes. Aims We evaluated the ability of the DeNitrification-DeComposition (DNDC) model to predict field-measured soil surface CO2 and N2O emissions in crop rotations managed with cover crop (CC) and without cover crop (NC) under the 27-year no-till field experiment in South Dakota, USA. Methods Emissions were measured in a 2-year corn–soybean and a 4-year corn–soybean–oat–winter wheat rotation. The model was calibrated with 2-year NC treatment and evaluated against three treatments (2-year CC, 4-year NC and 4-year CC) during the growing season of corn (2017) and soybean (2018). Key results Across all treatments, the model simulated soil temperature (MBE, −0.73–0.29°C; RMSE, 1.47–4.03°C; NSE, 0.54–0.90; d, 0.89–0.98; R2, 0.64–0.93) and moisture [water-filled porosity (wfps)] (MBE, 0.03–0.06 wfps; RMSE, 0.09–40.13 wfps; NSE, −0.24–0.49; d, 0.78–0.87; R2, 0.45–0.69) that agreed well with field measurements. Predicted daily soil CO2 fluxes (kg C ha−1) provided ‘good’ agreement with MBE (range −0.58−4.67), RMSE (range 2.10−7.36), d (range 0.68–0.93), NSE (range −0.92–0.79), and R2 (range 0.49–0.85). Statistics showed ‘poor’ agreement between the simulated and measured daily N2O emissions because peak emissions events in the measured data were less than predicted. Cumulative CO2 and N2O emissions and crop yields were well estimated by the model. Conclusions DNDCv.CAN simulated the impacts of diverse crop rotations and cover crops on soil moisture, temperature and greenhouse gas emissions in the humid south-east of USA. Implications Nitrogen transformation routines and effect of rainfall interception on soil water content need further investigation to address the variations in daily N2O emissions.
Mutant libraries reveal negative design shielding proteins from supramolecular self-assembly and relocalization in cells

Published: January 2022

Significance
Genetic mutations fuel organismal evolution but can also cause disease. As proteins are the cell’s workhorses, the ways in which mutations can disrupt their structure, stability, function, and interactions have been studied extensively. However, proteins evolve and function in a cellular context, and our ability to relate changes in protein sequence to cell-level phenotypes remains limited. In particular, the molecular mechanism underlying most disease-associated mutations is unknown. Here, we show that mutations changing a protein’s surface chemistry can dramatically impact its supramolecular self-assembly and localization in the cell. These results highlight the complex nature of genotype–phenotype relationships with a simple system.

Significance
The results provide strong evidence of extensive SARS-CoV-2 infection of white-tailed deer, a free-living wild animal species with widespread distribution across North, Central, and South America. The analysis shows infection of deer resulted from multiple spillovers from humans, followed by efficient deer-to-deer transmission. The discovery of widespread infection of white-tailed deer indicates their establishment as potential reservoir hosts for SARS-CoV-2, a finding with important implications for the ecology, long-term persistence, and evolution of the virus, including the potential for spillback to humans.
Exploring the dimensional relationships of story world absorption
Authors: Kuijpers Moniek M. 
Published: January 2022

Abstract
Absorption has proven to be an important mediator of reading enjoyment and persuasive text effects (Green & Brock, 2000; Kuijpers et al.,
2014). Typically, absorbing experiences with narrative media are captured using self-report measuring instruments. One such
instrument is the Story World Absorption Scale, which is comprised of four dimensions: Attention, Emotional Engagement, Mental
Imagery, and Transportation (Kuijpers et al., 2014). As of yet, we do not know how
these dimensions relate to one another. Data from four different studies (one survey and three experiments) using the Story World
Absorption Scale were investigated with the use of structural equation modeling to attempt to answer this question. The results
show that attention fulfills a crucial role in the absorption experience confirming the work of Kuiken and Douglas (2017, 2018) on absorption-like states. The
findings inspire a discussion on how we (should) use multi-dimensional instruments in the field of empirical literary studies.
Anomalous emission behavior of excitons at low temperature in monolayer WS2

Published: January 2022

Abstract
We report on the anomalous emission behavior of excitons (X) in monolayer WS2 using temperature dependent photoluminescence spectroscopy. In general, PL emission from excitons enhances with decreasing temperature due to suppression of phonon mediated non-radiative transitions. Here, we observe that excitonic PL is temperature independent, although with decreasing temperature, the emission intensity for trion (X
−) and biexciton or defect-bound excitons (XX/L
1) increases up to 123 K and then decreases. Analysis of experimental data with a model derived from the Boltzmann distribution and Saha equation reveal conversion of excitons into trions, biexcitons or defect-bound excitons and an increase of spin forbidden dark state with reduction in temperature. These findings could provide better strategies for designing future quantum devices.
Composition dependent phase structure, dielectric and electrostrain properties in (Sr0.7Bi0.2□0.1)TiO3–PbTiO3–Bi(Mg0.5Ti0.5)O3 systems

Abstract
Composition dependent transitions from normal ferroelectrics to nonergodic and finally to ergodic relaxor phase are observed in 0.7(Sr0.7Bi0.2□0.1)TiO3–(0.3 − x)PbTiO3–xBi(Mg0.5Ti0.5)O3 system (SBT–PT–xBMT, □ represents A–site vacancy). Rietveld refinement results show that with increasing BMT content, the system experiences a gradual transition from coexistence of pseudocubic and tetragonal (P
c + T) to P
c phase. The ferroelectric–relaxor phase transition and freezing temperature gradually decreases with addition of BMT content accompanied by an enhanced relaxor degree, which produces local disorder and polar nanodomains. This is also verified by Raman spectra and piezoelectric force microscopic analysis. The P–E loops transform from square to slant and finally to slim shape with increasing BMT component and an electric field-induced strain of ∼0.21% with ultralow hysteresis of ∼3.7% is obtained for x = 0.04 composition. The underlying mechanism for the large strain with low hysteresis lies in the existence of nonergodic and ergodic relaxor phase boundary and polar nanodomains at room temperature. Additionally, the multiphase coexistence contributes to a flatten free energy profile and thus contributing to such superior performances, as explained by a modified phenomenological model. High electrostrain with ultralow hysteresis in SBT–PT–xBMT systems are promising candidates in high–precision actuator applications.
Active tuning of resonant lattice Kerker effect
Authors: Xiong Lei , Ding Hongwei , Lu Yuanfu , Li Guangyuan 
Published: January 2022

Abstract
The Kerker effect has been generalized in nanophotonics and meta-optics, and has recently been of great interest by relating it to various fascinating functionalities such as scattering management and perfect transmission, reflection or absorption. One of the most interesting generalizations is the resonant lattice Kerker effect in periodic nanostructures. However, its active tuning has not been explored yet. Here, we report, for the first time, the active control of the resonant lattice Kerker effect in periodic Ge2Se2Te5 nanodisks. By changing the crystalline fraction, we show that the electric dipole surface lattice resonance (ED-SLR), the magnetic dipole resonance (MDR), and thus the resonant lattice Kerker effect are all red-shifted. We therefore realize the transition from the ED-SLR to the resonant lattice Kerker effect, which enables multilevel tuning of reflection, transmission and absorption with modulation depths above 86%. Taking advantage of the MDR redshifts, we also observe broadband and multilevel tuning of transmissions with modulation depth of 87% over a broadband range of 588 nm. Our work establishes a new path for designing high-performance active nanophotonic devices.

Published: January 2022

Abstract
In most applications, it is significant to understand how the composition and total pressure of the gas affect the sensitivity of a mass spectrometer for a specific composition of the gas. This work reports on the interference effects of the QMG700 quadrupole mass spectrometer (QMS) with the use of the ultrahigh vacuum partial pressure standard apparatus and standard leaks. Six combinations for Ar–H2, Ar–He, N2–H2, He–H2, He–N2 and CH4–N2–Ar–He–H2 gas mixtures were selected for the study of the instrument–gas interaction. The partial pressures of the interference gases varied in the range of 2.2 × 10−7–8.3 × 10−3Pa, and the total pressures of the calibration chamber ranged from 1.2 × 10−5Pa to 9.9 × 10−3 Pa. The detector of the QMS utilized only a Faraday cup, and the results demonstrated that the sensitivity of the trace gas was significantly affected by the interfering gas when the total pressure exceeded about 10−5 Pa. This study was also performed according to ISO TS 20175:2018.
