Authors: Sakuma Ryoko , Lin Kuan-Ting , Kajihara Yusuke 
Published: October 2023

AbstractIn this study, we passively analyzed the near-field characteristics of thermally excited evanescent waves, which are radiation waves generated by the local dynamics of materials, including electron motions and lattice vibrations. The thermally excited evanescent waves on aluminium nitride (AlN) and gallium nitride (GaN) were measured using passive spectroscopic scattering-type scanning near-field optical microscopy (s-SNOM) in the wavelength ranges of 10.5–12.2 μm and 14.0–15.0 μm, which include the surface phonon-polariton (SPhP) wavelength of the studied dielectrics. We determined the unique decay characteristics of AlN and GaN, indicating a ten-fold increase in the probe area contributing to the scattering of waves near the SPhP wavelength compared to that in other wavelength ranges. The extended probe area correlated with the polariton decay lengths, indicating that the non-enhanced polaritons around K ~ ω/c were dominant in the scattered waves near the SPhP wavelength. In addition to the conventional passive detection mechanisms for metals, the proposed detection scheme will be a versatile passive detection model in the near future.

AbstractArid soils are often weak, low in fertility, and lack essential plant nutrients. Organic amendments might be a feasible solution to counter the detrimental impact and rehabilitate weak arid soil for the growth of legumes. The study aimed to investigate how organic amendments of compost and humic acid may affect winter field pea productivity in arid soil. Over 2 years of field experiments, a range of treatments were applied, including different amounts of compost and humic acid. The results showed higher microbial carbon (C), and nitrogen (N) biomass, root length, shoot length, grains pod−1, and grain yield of pea, gained from the collective application of 8 Mg ha−1 compost and 15 kg ha−1 humic acid compared to all other treatments. Organic amendments increased soil microbial C density by 67.0 to 83.0% and N biomass by 46.0 to 88.0% compared with the control. The combined application of compost and humic acid increased soil microbial N biomass by 57.0 to 60.0% compared to the sole applications of compost-only and humic acid-only. It was concluded that organic amendments of 8 Mg ha−1 compost and 15 kg ha−1 humic acid in arid soil modulated microbial density, resulting in improved winter field pea productivity. This study suggests organic amendments of compost and humic acid might be a practicable solution to rehabilitate weak arid soil to grow legumes.

Published: October 2023

AbstractThe supply chain management (SCM) of COVID-19 vaccine is the most daunting task for logistics and supply managers due to temperature sensitivity and complex logistics process. Therefore, several technologies have been applied but the complexity of COVID-19 vaccine makes the Internet of Things (IoT) a strong use case due to its multiple features support like excursion notification, data sharing, connectivity management, secure shipping, real-time tracking and monitoring etc. All these features can only feasible through choosing and deploying the right IoT platform. However, selection of right IoT platform is also a major concern due to lack of experience and technical knowledge of supply chain managers and diversified landscape of IoT platforms. Therefore, we introduce a decision making model for evaluation and decision making of IoT platforms that fits for logistics and transportation (L&T) process of COVID-19 vaccine. This study initially identifies the major challenges addressed during the SCM of COVID-19 vaccine and then provides reasonable solution by presenting the assessment model for selection of rational IoT platform. The proposed model applies hybrid Multi Criteria Decision Making (MCDM) approach for evaluation. It also adopts Estimation-Talk-Estimation (ETE) approach for response collection during the survey. As, this is first kind of model so the proposed model is validated and tested by conducting a survey with experts. The results of the proposed decision making model are also verified by Simple Additive Weighting (SAW) technique which indicates higher results accuracy and reliability of the proposed model. Similarly, the proposed model yields the best possible results and it can be judged by the precision, accuracy and recall values i.e. 93%, 93% and 94% respectively. The survey-based testing also suggests that this model can be adopted in practical scenarios to deal with complexities which may arise during the decision making of IoT platform for COVID-19 SCM process.

AbstractThe link between aerosol dynamics and viral exposure risk is not fully understood, particularly during movement and face-to-face interactions. To investigate this, we employed Particle Trace Velocimetry with a laser sheet and a high-speed camera to measure microparticles from a human mannequin’s mouth. The average peak time in the non-ventilated condition (expiratory volume, 30 L; passing speed, 5 km/h) was 1.33 s (standard deviation = 0.32 s), while that in the ventilated condition was 1.38 s (standard deviation = 0.35 s). Our results showed that the peak of viral exposure risk was within 5 s during face-to-face encounters under both ventilated and non-ventilated conditions. Moreover, the risk of viral exposure greatly decreased in ventilated conditions compared to non-ventilated conditions. Based on these findings, considering a risk mitigation strategy for the duration of 5 s during face-to-face encounters is expected to significantly reduce the risk of virus exposure in airborne transmission.

AbstractPelvic organ prolapse (POP) is a benign gynecological disease in which the pelvic organ descends into the vagina and causes voiding, and defecatory dysfunction, mainly occurs in older women. This study aimed to investigate the vaginal microbiome of POP and associated changes after anatomical restorative pessary or reconstructive pelvic operation. We analyzed the vaginal microbiome using 16S ribosomal RNA gene sequencing and compared the results among patient groups with POP, pessary, and postoperation. We also measured 10 inflammation-related cytokines in vaginal swab samples using multiplex immunoassay. In pelvic organ prolapse, vaginal community status type IV was the most prevalent, which showed a low abundance of Lactobacillus with increased diversity and abundance of anaerobic species. The alpha diversity of species richness was highest in the POP group. The beta diversity distance differed significantly between the three groups (p = 0.001). While human intestinal taxa-associated bacteria were reduced after pessary or operation, vaginitis-associated bacterial composition was altered but vaginal microbiome homeostasis was not improved. IFN-γ, IL-10, IL-12p70, IL-1β, IL-4 and TNF-α levels increased in the pessary group. Therefore, in addition to anatomical restorative treatment, supplementary treatment focusing on the recovery of the vaginal microbiome may be needed to maintain the health of gynecological organs in old age.

AbstractThe intestinal epithelium is highly regenerative. Rapidly proliferating LGR5+ crypt base columnar (CBC) cells are responsible for epithelial turnover needed to maintain intestinal homeostasis. Upon tissue damage, loss of LGR5+ CBCs can be compensated by activation of quiescent +4 intestinal stem cells (ISCs) or early progenitor cells to restore intestinal regeneration. LGR5+ CBC self-renewal and ISC conversion to LGR5+ cells are regulated by external signals originating from the ISC niche. In contrast, little is known about intrinsic regulatory mechanisms critical for maintenance of LGR5+ CBC homeostasis. We found that LGR5 expression in intestinal crypt cells is controlled by the circadian core clock gene BMAL1 and the BMAL1-regulated RNA-binding protein MEX3A. BMAL1 directly activated transcription of Mex3a. MEX3A in turn bound to and stabilized Lgr5 mRNA. Bmal1 depletion reduced Mex3a and Lgr5 expression and led to increased ferroptosis, which consequently decreased LGR5+ CBC numbers and increased the number of crypt cells expressing +4 ISC marker BMI1. Together, these findings reveal a BMAL1-centered intrinsic regulatory pathway that maintains LGR5 expression in the crypt cells and suggest a potential mechanism contributing to ISC homeostasis.

Published: October 2023

AbstractBecause of their tissue‐like mechanical performances, high biocompatibility, and adjustable functionality, hydrogels have become increasingly attractive materials for promoting wound healing. Chronic wounds include burn, diabetic, and infected wounds. Unlike common incision wounds, chronic wounds are more challenging to heal. To meet the clinical needs, multifunctional hydrogels should be fabricated and investigated. To guide future studies on the fabrication of hydrogel‐based chronic wound dressings, a review of advanced multifunctional hydrogels is necessary. Various hydrogels with advanced properties, such as antibacterial, antioxidant, bioadhesive, anti‐inflammatory, and wound healing properties, that can be used for skin burn wounds and diabetic wounds are summarised. Lastly, the prospects of advanced hydrogels for wound healing are elaborated.
Mitigation of Deane and Hamill phenomenon in gallium nitride high‐voltage power supply for electric propulsion system application

Published: October 2023

AbstractThe step‐up resonant converters are widely adopted to provide high voltage in kV‐level for electric propulsion system due to their high efficiency, low mass, modularisation, and high‐power density. The bipolar Cockcroft‐Walton voltage multiplier (BiCWVM) is a major circuit that steps up the voltage in the resonant converter. However, the diode non‐linearity in BiCWVM can introduce self‐sustained quasi‐periodic oscillations in the voltage and current waveforms, which is commonly known as the Deane and Hamill (DH) phenomenon. The oscillation can lead to higher magnetic loss and control failure, and it is more likely to present in the gallium nitride‐based converter due to the high‐frequency operation. The authors aim to investigate and mitigate the DH phenomenon systematically so that proper mitigation can be implemented. To facilitate the investigation, the circuit before the BiCWVM in the converter is derived and modelled as a voltage source vm and a series inductor Lsy. Also, the reverse recovery process of the diode in the BiCWVM can be represented by a piecewise‐linear (PWL) model, with the simplified circuit and PWL model, the relationship between voltage and current under different operating conditions can be determined with ease. The relationship allows to understand the mechanism of diode reverse recovery in BiCWVM that leads to DH phenomenon. Finally, a hybrid‐/full‐silicon carbide (SiC) design is proposed to mitigate the DH phenomenon, which is verified experimentally for a 300‐kHz, 5‐W, 20‐V/1.5‐kV GaN‐based step‐up resonant converter.
A new approach for harmonic detection based on eliminating oscillatory coupling effects in microgrids

Published: October 2023

AbstractThe primary goal of grid‐connected microgrids is to control the active and reactive power, which is reachable by the inner current control loop in the control structure of power converters. However, when facing unbalanced conditions, the inner current control loop implemented in the dq frame does not function properly. In such conditions, the popular current control loop malfunctions since there is an oscillatory coupling between harmonic components. Therefore, in this study, a new harmonic detector based on decoupled double synchronous reference frame within the current control loop is proposed in which the oscillatory coupling between harmonic components is eliminated, and the overall performance of the power converter control system is significantly improved. The performance of the precisely developed mathematical models is verified by Matlab simulations, and the simulation results confirm the accuracy and proper operation of the proposed strategy.
A novel integrity monitoring method for slowly growing errors in inertial navigation system/global navigation satellite system integrated navigation system
Authors: Yang Shaohua , Zhang Xiaodong , Wang Guanjie , Zhang Rui , Li Zhenwei 
Published: October 2023

AbstractAn integrity monitoring of integrated navigation in the presence of slowly growing errors (SGEs) is proposed. SGEs with gradual growth over time are the worst category of latent failures. Tightly coupled inertial navigation system (INS)/Global Navigation Satellite System integration is presented by taking INS errors, bias and drift of receiver clock, baro‐altitude, pseudo‐range errors and ionospheric errors into consideration. Based on the RTCA performance standards DO‐229 and DO‐384, the simplified multi‐filters solution separation is employed for fault detection and calculation of corresponding outputs. For the fault exclusion part, the authors introduce a post pseudo‐range residual and measurement averaging method that is designed to quickly and effectively address SGEs and large measurement noises. Furthermore, the authors have designed a reconstruction logic for the filters that guarantees the continuity of the civil aviation system by considering the variation of visible satellites and historical information. The simulation results demonstrate that the proposed approach satisfies the performance requirements for civil aviation of En‐route and is able to correctly exclude faults and respond quickly in the presence of different levels of SGEs and measurement noises.
Low complexity beamspace super‐resolution for direction‐of‐arrival estimation via prior information encoding
Authors: Jie Pan 
Published: October 2023

AbstractBeamspace processing is widely applied in Direction‐of‐Arrival (DOA) estimation thanks to dimensional reduction and super‐resolution characterisations. However, the conventional atomic norm minimisation (ANM) based methods for beamspace DOA estimation are of high computational complexity for large arrays. To deal with this issue, the proposed method focuses on locating the sources in the mainlobe of the beamspace and encodes such prior information into the ANM problem without frequency‐selective constraints. The proposed method approximates the beamspace array manifold in the mainlobe sector with the truncated sector Fourier series. The theoretical analysis shows that such approximation with the properly designed fitting error relaxation on the boundary yields the low dimensional semidefinite programming (SDP) approximate implementation of the proposed ANM method and guarantees the support recovery inside the mainlobe. Furthermore, the low complexity Burer‐Monteiro factorisation based alternating direction method of multipliers method is proposed to solve the SDP problem. The complexity analysis and simulations show that the proposed method results in significant computational complexity reduction and slightly better performance compared with state‐of‐art benchmarks.

Published: October 2023

Three colloidal plasma expanders for use during cardiopulmonary bypass were compared in 85 patients treated at four Japanese hospitals. Patients were randomly allocated to receive: Hydroxyethyl Starch (HES) 5 ml/kg, HES 10 ml/kg, gelatin (Haemacel 10 ml/kg), or a mixture of HES 5 ml/kg and low viscosity dextran (LVD) 5 ml/kg, in addition to the usual priming dose of 1000-1500 ml Lactated Ringer's solution, 20 gm/dl mannitol, and heparinized whole blood. These colloidal plasma expanders appeared equivalent in safely replacing whole blood. Following surgery, urine outputs increased slightly, there were transient elevations of SGOT, LDH, and serum bilirubin, and transient decrements in serum alkaline phosphatase, Na, K, and Cl concentrations. Serum protein, one week following surgery was decreased, possibly reflecting persistence of the plasma expanders. There was no increased bleeding or prolongation of clotting times, bleeding times, or prothrombin times, even though platelet counts were low following surgery. Plasma hemoglobin concentrations were greater in patients receiving gelatin as compared with those given HES. Hydroxyethyl Starch (6 gm/dl), a new plasma expander, appears to be efficacious and nontoxic in hemodilution extracorporeal perfusion.
The priming solution employed in the extracorporeal circuit has undergone refinement to limit denaturation of blood and consequent clinical sequelae.5,29,30,40 Initially, heparinized whole blood primed the circuit, but the possibility of incompatible blood administration, transmission of viral hepatitis, and nonhemolytic reactions of a febrile or allergic nature became apparent with the use of homologous blood.10,23 Development and improvement of colloidal and crystalloid solutions for hemodilution, has conserved blood and prevented adverse effects attendant upon blood transfusion.12,19,21,24 The use of hemodilution has allowed prolongation of the perfusion period, expanding the application of open heart surgery.21
The present study compares the efficacy and toxicity of hydroxyethyl starch (HES) and gelatin in 85 patients during open heart surgery.

Abstract
Objective The availability of reliable and inexpensive markers that can be used to determine the risk of rupture during methotrexate (MTX) treatment in ectopic pregnancies (EPs) is considerable. The aim of the present study is to investigate the role of systemic inflammatory markers such as leukocytes (or white blood cells, WBCs), the neutrophil-to-lymphocyte ratio (NLR), and platelet distribution width (PDW), which are among the parameters of the complete blood count (CBC), in the prediction of rupture of EPs under MTX treatment.
Materials and Methods A total of 161 patients with tubal EP who underwent a single-dose methotrexate (MTX) protocol were retrospectively analyzed, and the control group (n = 83) included patients cured by MTX, while the ruptured group (n = 78) included patients who were operated on for tubal rupture during the MTX treatment. The features of EP, beta-human chorionic gonadotropin (β-hCG) levels, sonographic findings, and CBC-derived markers such as WBC, NLR, and PDW, were investigated by comparing both groups.
Results The NLR was found to be higher in the ruptured group, of 2.92 ± 0.86%, and significantly lower in the control group, of 2.09 ± 0.6%. Similarly, the PDW was higher (51 ± 9%) in the ruptured group, and it was significantly lower a (47 ± 13%) in the control group (p < 0.05). Other CBC parameters were similar in both groups (p > 0.05).
Conclusion Systemic inflammation markers derived from CBC can be easily applied to predict the risk of tubal rupture in Eps, since the CBC is an inexpensive and easy-to-apply test, which is first requested from each patient during hospitalization.

Abstract
Objective Gestational diabetes can cause maternal and neonatal morbidity. Psychological factors, especially stress, play a meaningful role in diabetes management. Therefore, the present study aimed to investigate the effect of Mindfulness-Based Stress Reduction counseling on blood sugar and perceived stress in women with gestational diabetes.
Methods The present quasi-experimental interventional study was performed on 78 women with gestational diabetes. In the intervention group, a Mindfulness-Based Stress Reduction counseling program was conducted by the researcher in 8 sessions of 90 minutes twice a week. The Cohen stress questionnaire was filled in both groups. Also, fasting blood sugar and 2-hour blood sugar levels were measured in both groups. Statistical analysis was performed using the independent T-Test, the paired T-Test, the Mann-Whitney and Wilcoxon Tests using IBM SPSS Statistics for Windows version 20 version (IBM Corp., Armonk, NY, USA).
Results The mean age of pregnant women in the intervention group was 28.84 ± 6.20 years old and 29.03 ± 5.42 years old in the control group. There was a significant mean difference between the fasting blood sugar score (p = 0.02; - 6.01; and - 11.46) and the 2-hour fasting blood sugar score (p < 0.001;12.35; and - 5.3) and the perceived stress score (p < 0.001; 35.57; and - 49.19) existed between the intervention and control groups after the intervention.
Conclusion The results of the present study showed that mindfulness-based stress reduction counseling is effective in reducing blood sugar levels and reducing perceived stress in women with gestational diabetes treated with diet.
