Authors: Ralston Lauren , Campbell Julia , Gilley Phillip , Nielson Mashhood , Brown Kristopher 
Published: January 2024

Purpose:
The goal of this study was to observe sensory gating–related networks underlying cortical auditory evoked potential (CAEP) peak components in individuals with and without minimal tinnitus, as measured using the Tinnitus Handicap Inventory (THI). This analysis was performed on previously published sensory gating responses in normal-hearing adults with and without minimal tinnitus.

Method:
Independent component analysis was performed for each individual CAEP gating component (Pa, P50, N1, and P2). Significant components were retained for source localization analyses within the following groups: no tinnitus, tinnitus with a THI score ≤ 6, and tinnitus with a THI score > 6. Brain source localization was performed on the gating difference wave for each component using standardized low-resolution brain electromagnetic tomography.

Results:
Gating-related networks were identified within each group. Different regional sources were observed between groups, with parietal sources underlying the Pa and P50 components as tinnitus severity increased. A larger prefrontal regional activation was also shown for the N1 gating component as tinnitus severity increased. These results expand upon the functional gating responses via CAEP waveforms in a previously published study.

Conclusions:
The auditory gating response, as measured via CAEPs, has previously been shown to significantly correlate with an increase in tinnitus severity in adults with normal hearing. The corresponding changes in the gating response appear to be supported by different cortical regions in those without tinnitus, those with a THI score ≤ 6, and those with a THI score > 6. Next, functional differences between localized cortical regions should be tested.
An efficient adaptive h‐refinement for the RWG‐based electric field integral equation applied to antennas with waveport

Published: January 2024

AbstractAn approximation scheme that combines approximate solutions with error estimators to accelerate the adaptive h‐refinement of the RWG‐based method of moments (MoM) with the electric field integral equation (EFIE) is presented. The scheme is effectively implemented by using the near‐field matrix to solve the approximate solution. Several conventional error estimators incorporated with the scheme are investigated. Compared to using the full MoM system, it significantly reduces the computational cost while maintaining the refinement effect. Numerical results indicate that the scheme could accelerate the adaptive refinement, yielding significant reductions in computational time and memory requirements.
Digitale Gesundheitsversorgung. Anforderungen an eine erfolgreiche
Transformation
Authors: Steidle Oliver , Rego Kerstin , Petzold Thomas 
Published: January 2024

ZusammenfassungDie digitale Transformation der Gesundheitsversorgung ist das bestimmende
Diskussionsthema aller Akteure im Gesundheitswesen. Digitale Transformation
umfasst alle Bereiche der Gesundheitsversorgung und ist weit mehr als digitale
Gesundheitsanwendungen (DiGA), digitale Pflegeanwendungen (DiPA),
telemedizinische Anwendungen, Aktivitäten zur Telematikinfrastruktur
sowie Anwendungen aus den Bereichen eHealth, mHealth oder Telehealth. Jegliche
bestehenden Versorgungsprozesse und auch Strukturen im Gesundheitswesen
unterliegen einer Bestandsaufnahme, um analoge Bestandteile der Versorgung in
einen digitalen Kontext zu überführen [1,2]. Die digitale
Transformation findet nicht ausschließlich in Wirtschaftssektoren, wie
dem Gesundheitswesen, statt, sondern ist ein gesamtgesellschaftlicher
Veränderungsprozess in der Erhebung, Nutzung, Bereitstellung,
Verknüpfung und Auswertung von Informationen (=Daten).
Für das Gesundheitswesen wird deutlich, dass unterschiedliche technische
Konzepte eingesetzt werden, digitale Gesundheitsversorgung an unterschiedlichen
Orten und zu unterschiedlichen Zeiten stattfindet, ggf. unterschiedliche
Nutzer(kreise) umfasst und den Versorgungskontext beibehält, erweitert
oder wechselt. Etablierte Funktionen der Gesundheitsversorgung, wie Diagnostik,
Therapie, Dokumentation und das Management von Gesundheitsleistungen bleiben
erhalten und werden in einen digitalen Kontext überführt.
Zusätzlich werden neue Anwendungsbereiche entstehen, wie der
übergreifende Zugriff auf Gesundheitsdaten durch verschiedene Akteure,
echtzeitgetriebene Monitoringsysteme ganzheitlicher Gesundheitsdaten,
(klinische) Entscheidungssysteme oder die Bereitstellung von Daten für
die Versorgungsforschung [2]. Auch wenn der Großteil der digitalen
Transformation noch nicht stattgefunden hat wird davon ausgegangen, dass diese
Funktionen und Anwendungsbereiche der Gesundheitsversorgung dienen, die
Versorgungsqualität nachhaltig zu verbessern [4] und dem Wohle aller
(zukünftigen) Patienten zu Gute zu kommen [5]. Für die
Überführung bestehender Prozesse in einen digitalen Kontext und
die Etablierung neuer Anwendungsbereiche ergeben sich für Einrichtungen
der Gesundheitsversorgung und das Gesundheitssystem selbst Voraussetzungen, die
im Folgenden vorgestellt werden.

AbstractThough opioids can be very effective for postoperative pain management after revision total hip arthroplasty (rTHA), many physicians have made an effort to decrease usage of these medications by focusing on alternative pain management strategies to reduce opioid dependence and unwanted side effects. This study sought to investigate trends in opioid consumption during hospitalization following rTHA from 2016 to 2021. We retrospectively reviewed all patients who received rTHA from January 2016 to April 2021. Baseline demographic variables including age, gender, race, body mass index, and American Society of Anesthesiologists classification were recorded. Additional information including patient-reported outcome measures (PROMs), postoperative outcomes, dosage, and type of opioid medication prescribed postoperatively were also collected. Opioid dosage and type were converted to milligram morphine equivalents (MMEs) per day of hospitalization and compared across the 6 years studied. Linear regression as well as t-tests were utilized to determine significant trends in MME consumption over time. In total, 1,096 patients met inclusion and exclusion criteria. The greatest daily average opioid consumption per patient was in 2017 (61.6 ± 155.4 MME per day) and the lowest was in 2021 (31.8 ± 105.8 MME per day). Linear regression analysis detected a downward trend of 4.97 MME per day each year, though these results were not statistically significant (R
2: 0.444, p = 0.089). t-Test analysis, however, did reveal a significant decrease in opioid consumption in the postprotocol cohort (38.41 ± 90.5 vs. 52.18 ± 120.2; p = 0.034). There was a significant increase in preoperative Hip Disability and Osteoarthritis Outcome Score, Joint Replacement scores (p = 0.007) over time as well as a significant decrease in preoperative visual analog scale pain scores (p = 0.012). The results of this study show that opioid consumption in 2021 was lower than in 2016 and 2017. This result emphasizes the effectiveness of protocols limiting opioid usage during hospitalization following rTHA. Moreover, the relatively consistent patient-reported outcome scores over time demonstrate that this decrease in opioid consumption per year does not impact patient-reported outcomes and satisfaction.

Published: January 2024

The unique characteristics, such as high magnetic moment, high Curie temperature, large magnetic crystalline anisotropy, and low cost, make the τ-phase MnAl a promising candidate as the market alternatives which could fill the gap between the rare earth magnets and ferrite magnets. Because at low temperatures the metal will become more brittle, the cryomilling technology may allow the τ-phase MnAl to be broken quickly and introduce few crystal defects, and then obtain better permanent magnetic properties. In this study, the cryomilling technology was used to grind the τ-phase MnAl, and the structural and magnetic properties of the obtained powder sample were investigated. It was found that compared to room-temperature ball milling, the morphology of cryomilled powders is granular and the powder agglomeration is dramatically suppressed at a low temperature, and as a result the larger particles tend to be broken down into smaller ones rather than being agglomerated to larger thin layers. The grain size D reduced continuously from 145 nm to 36 nm when the sample was milled for 120 minutes. The coercivity increased with increasing the cryo-milling time, while the saturation magnetization decreased. The maximum coercivity of up to 4.9 kOe was obtained by cryo-milling for 100 minutes. By the neutron diffraction analysis, it was confirmed that the decrease of the saturation magnetization with increasing milling time is mainly due to the migration of Mn atoms from 1a site to the 1d site and the decrease of Mn atomic magnetic moment.
Effect of relationship between magnetic moment energy variation and knee point squareness ratio on transformer noise
Authors: Hsu Chang-Hung 
Published: January 2024

This paper presents the effects of the magnetostriction of core loss and noise (sound level) on power transformers between 15 and 120 MVA and the results of an analysis relative to the parameters of the squareness ratio (SR). Three types of soft magnetic silicon steel were used in this study: 30ZH105, 27ZH100, and 27PH100. The hysteresis loop and magnetostriction were measured for various magnetic parameters of sound level and core loss. Moreover, finite element analysis was performed to indicate the flux density and the parameter of ΔBr variation dependent on transformer loss and noise. The design values for transformers with several capacities, with respect to sound level and core loss performance were compared. Studies have indicated that transformer noise includes hysteresis and the volume of ferromagnetic materials. The sound level performance displayed a lower noise result because of the core with a higher SR. Besides, it can be observed that the material has innate magnetic anisotropy and the greater the magnetic moment flip energy then induced higher the noise. Additionally, it was observed that a higher SR. of 27ZH100 for core loss was not significant. When the SR. with respect to the sound level was high, the experimental and design values were very similar by using fast Fourier transform to observe the noise operated at a different frequency spectrum between 50 Hz and 10 kHz. The design values for transformers with varying capacities, with respect to the sound level and core loss performance were analyzed and compared with the experimental values.
Dumbbell-like Au–Fe3O4 nanoparticles for magnetic hyperthermia
Authors: Tonthat Loi , Ogawa Tomoyuki , Yabukami Shin 
Published: January 2024

Dumbbell-shaped hybrid nanoparticles, consisting of gold and iron oxide (Au-Fe3O4 NPs), show promise for magnetic hyperthermia cancer therapy. However, conventional synthesis methods using toxic iron pentacarbonyl (Fe(CO)5) raise safety concerns. We propose a safer approach using triiron dodecacarbonyl (Fe3(CO)12) as a precursor. We synthesize these NPs by initially reducing gold (III) chloride trihydrate with a tert-butylamine-borane complex at room temperature, yielding Au NPs. These Au NPs are combined with a Fe3(CO)12 solution and heated to 300 °C for 1 hour, resulting in the desired dumbbell-shaped Au-Fe3O4 NPs. Characterization confirms their morphology, with average sizes of 5 nm for Au NPs and 15 nm for Fe3O4 NPs. Our systematic evaluation of hydrophilic-treated Au-Fe3O4 NPs (Ms=49.5 emu/g at 3T, 300K) demonstrates temperature increases beyond the therapeutic threshold of 45 °C (ΔT=8 °C) at higher field strengths (8.6–30.0 kA/m), highlighting their cancer treatment potential. Quantitative analysis reveals superb performance, with a specific absorption rate (SAR) of 60.0 W/g and intrinsic loss power (ILP) of 0.25 nHm2kg−1 at the maximum field strength. These findings emphasize the significant potential of our dumbbell-shaped Au–Fe3O4 NPs for magnetic hyperthermia.
How face is perceived in Chinese and Japanese
Authors: Xiao Qi , Zhou Ling 
Published: January 2024

Abstract
This study aims to examine how Chinese and Japanese speakers perceive face-enhancement and face-threat from a
value-construct perspective. A mixed-method research design consisting of a questionnaire and structured interviews was employed.
The results suggest that the values which trigger face-enhancement and face-threat are differently distributed between the two
linguacultures in face-threatening and face-enhancing situations. Both Chinese and Japanese participants agreed that competence
was the top value for face-enhancement. The Chinese participants considered status superiority as the more sensitive triggering
value of face-enhancement, whereas the Japanese participants believed that good public image, self-esteem, and pride were the main
factors. In face-threatening scenarios, the Japanese participants paid more attention to self-abasement and shame, inconsideration
and irresponsibility, whereas the Chinese were more sensitive to incompetence. We attribute these differences in individuals’
perspectives on interpersonal relationships as a possible cause of their divergent perceptions of face.

Abstract
In this letter, high power density AlGaN/GaN high electron-mobility transistors (HEMTs) on a freestanding GaN substrate are reported. An asymmetric Γ-shaped 500-nm gate with a field plate of 650 nm is introduced to improve microwave power performance. The breakdown voltage (BV) is increased to more than 200 V for the fabricated device with gate-to-source and gate-to-drain distances of 1.08 and 2.92 μm. A record continuous-wave power density of 11.2 W/mm@10 GHz is realized with a drain bias of 70 V. The maximum oscillation frequency (f
max) and unity current gain cut-off frequency (f
t) of the AlGaN/GaN HEMTs exceed 30 and 20 GHz, respectively. The results demonstrate the potential of AlGaN/GaN HEMTs on free-standing GaN substrates for microwave power applications.

Published: January 2024

Abstract
Two-dimensional (2D) WSe2 has received increasing attention due to its unique optical properties and bipolar behavior. Several WSe2-based heterojunctions exhibit bidirectional rectification characteristics, but most devices have a lower rectification ratio. In this work, the Bi2O2Se/WSe2 heterojunction prepared by us has a type Ⅱ band alignment, which can vastly suppress the channel current through the interface barrier so that the Bi2O2Se/WSe2 heterojunction device has a large rectification ratio of about 105. Meanwhile, under different gate voltage modulation, the current on/off ratio of the device changes by nearly five orders of magnitude, and the maximum current on/off ratio is expected to be achieved 106. The photocurrent measurement reveals the behavior of recombination and space charge confinement, further verifying the bidirectional rectification behavior of heterojunctions, and it also exhibits excellent performance in light response. In the future, Bi2O2Se/WSe2 heterojunction field-effect transistors have great potential to reduce the volume of integrated circuits as a bidirectional controlled switching device.

Published: January 2024

Abstract
The upgrade of the China Spallation Neutron Source (CSNS-II) encompasses the development of a dual harmonic RF system for the Rapid Cycling Synchrotron (RCS). The objective of this system is to achieve a maximum second harmonic voltage of 100 kV. To meet this requirement, a high gradient cavity is being used in place of the traditional ferrite loaded cavity. Magnetic alloy (MA) loaded cavities, which can attain very high field gradients, have demonstrated their suitability for high-intensity proton synchrotrons. As a result, designing an RF system with MA-loaded cavities has emerged as a primary focus. Over the past decade, substantial advancements have been made in the development of MA-loaded cavities at CSNS. This paper provides an overview of the RF system that incorporates the MA-loaded cavity and presents the high-power test and beam test results of the system.

AbstractThe suitable microenvironment of bone regeneration is critically important for periodontitis-derived bone defect repair. Three major challenges in achieving a robust osteogenic reaction are the exist of oral inflammation, pathogenic bacteria invasion and unaffluent seed cells. Herein, a customizable and multifunctional 3D-printing module was designed with glycidyl methacrylate (GMA) modified epsilon-poly-L-lysine (EPLGMA) loading periodontal ligament stem cells (PDLSCs) and myeloid-derived suppressive cells membrane vesicles (MDSCs-MV) bioink (EPLGMA/PDLSCs/MDSCs-MVs, abbreviated as EPM) for periodontitis-derived bone defect repair. The EPM showed excellent mechanical properties and physicochemical characteristics, providing a suitable microenvironment for bone regeneration.In vitro, EPMs presented effectively kill the periodontopathic bacteria depend on the natural antibacterial properties of the EPL. Meanwhile, MDSCs-MV was confirmed to inhibit T cells through CD73/CD39/adenosine signal pathway, exerting an anti-inflammatory role. Additionally, seed cells of PDLSCs provide an adequate supply for osteoblasts. Moreover, MDSCs-MV could significantly enhance the mineralizing capacity of PDLSCs-derived osteoblast. In the periodontal bone defect rat model, the results of micro-CT and histological staining demonstrated that the EPM scaffold similarly had an excellent anti-inflammatory and bone regeneration efficacyin vivo. This biomimetic and multifunctional 3D-printing bioink opens new avenues for periodontitis-derived bone defect repair and future clinical application.

Published: January 2024

Abstract
In this study, we explored the green synthesis of metal nanoparticles (Ag-NPs, Au-NPs, and Pd-NPs) using Moringa oleifera seed (MOS) extract, which is known for its nutrient density, antioxidant properties, anti-inflammatory effects, and potential benefits in managing cholesterol, blood sugar levels, as well as promoting digestion, skin, and hair health. The nanoparticles’ size was controlled by varying the concentration of MOS extract. The successful formation of Au-NPs and Ag-NPs was confirmed through surface plasmon resonance (SPR), while the absence of absorption at 420 nm indicated the reduction of Pd2+ ions to Pd0, affirming the synthesis of Pd-NPs. The nanoparticles exhibited mono-dispersed, spherical shapes with confirmed crystallinity. Sizes were determined as 28 nm for Pd-NPs, 5 nm for Au-NPs, and 19 nm for Ag-NPs. The MOS extract’s phenols and proteins played a crucial role in reducing and stabilising Ag-NPs, Au-NPs, and Pd-NPs. Notably, the synthesised nanoparticles demonstrated strong antimicrobial activity, particularly against Salmonella typhi, making them potential antibacterial agents. The catalytic efficiency of Au-NPs, Ag-NPs and Pd-NPs was studied using the reduction of 4-Nitrophenol (4-NP) by NaBH4 to 4-Aminophenol. Additionally, Au-NPs showed enhanced photocatalytic degradation rate constant and catalytic reaction rate constant of 0.0038/min and 0.261/min respectively, due to their small size and increased surface area. By combining a green synthesis approach with an in-depth analysis of properties and diverse applications, this study provides valuable insights into the immense potential of MOS-assisted metal nanoparticles for various technological and environmental advancements.
