Design and Analysis of Consequent-Pole Permanent Magnet Vernier Motor With Cancellation of Even-Order Harmonics

This article develops a method for the cancellation of the inherent even-order harmonics in consequent-pole permanent-magnet vernier motors (CP-PMVMs) to improve the performance. Vernier motors can achieve high torque density; however, their high pole number means a high amount of rare-earth permanent magnet (PM) usage at a high cost. The consequent-pole design can reduce PM material cost but leads to high even-order harmonics and torque ripple. This article analyzes two winding configurations in order to develop the method for even-order harmonics cancellation in the CP-PMVMs. Two CP-PMVMs with different slot–pole combinations are analyzed to verify the proposed method. The effect of magnetic barriers on the torque output of the CP-PMVM with canceled even-order harmonics is evaluated. Finally, a multi-objective genetic algorithm is used to optimize the motor. Finite element analysis (FEA) is used to validate the design, with subsequent confirmation of simulations through prototype testing.
The Students’ Perception of the Teacher’s Facilitation in Online Group Work

This research examines the students’ perception of the teacher’s facilitation in online group work in English for Managers class at the Faculty of Business and Economics, Universitas Atma Jaya Yogyakarta. The study employed The Community of Inquiry (CoI) framework perspective, which consists of teaching presence, cognitive presence, and social presence. CoI has been widely employed in designing practical online courses. Thus, this descriptive qualitative research analyzed students’ perceptions of facilitation in online group work using questionnaires and interviews. The research participants were English for Managers students. They were selected since they have experience participating in online group work. The results of the study show that most of the participants have demonstrated to possess a positive perception of the teacher’s facilitation in online group work in EFM class at FBE UAJY.
MINERALOGY OF PRESOLAR SILICATE AND OXIDE GRAINS OF DIVERSE STELLAR ORIGINS

We report the chemical and structural analysis of nine presolar silicate grains and one presolar oxide grain from the ungrouped chondrite Acfer 094 and the CR chondrite Queen Alexandra Range 99177. Oxygen isotopic analyses indicate that five of these grains condensed in the outflows of asymptotic giant branch (AGB) stars, four have supernova (SN) origins, and one grain likely has a nova origin. Transmission electron microscopy studies show that most of the grains are amorphous with widely varying non-stoichiometric chemical compositions. Three crystalline AGB grains were identified: a clinoenstatite-containing grain assemblage, a Fe-rich olivine grain, and a nanocrystalline enstatite grain encased in an amorphous silicate shell. An amorphous stoichiometric enstatite (MgSiO3) SN grain likely condensed as a crystal and was later rendered amorphous. We do not observe a systematic difference in the chemistries and mineralogies of presolar silicates from different stellar sources, suggesting that the grains formed under a similar range of conditions.
GENDER DIFFERENCES IN VOCATIONAL INTERESTS ACROSS THREE BALKAN COUNTRIES

The main objective of the study was to examine gender differences in vocational interests across three neighboring Balkan countries – Bulgaria, North Macedonia, and Serbia. Vocational interests were operationalized through the spherical model of vocational interests and Holland’s RIASEC circumplex model. The study reanalyzed data from previously published studies that collected vocational interest data from these countries. Participants of the study were 2536 young people, bachelor students in case of Bulgaria and North Macedonia and young people, with a high proportion of students, in the case of Serbia. They completed the Personal Globe Inventory. The results showed large gender differences along the People-Things dimension with Cohen’s d values ranging between 1.34 and 1.5 in the three country subsamples. Males tended to have higher preferences for jobs and activities that involved working with things than females, while females tended to have higher preferences for jobs and activities involving working with people than males. A substantial difference, but of smaller magnitude, was found in all three countries on the vocational interest dimension of Prestige, with females having higher scores than men. This difference came partly from higher preferences of women for high prestige jobs compared to men, but to a much greater extent from a much lower preference of women for low prestige jobs and activities compared to men. Comparisons were also made on vocational interest types and the largest differences found corresponded to those found in other world countries.
Mean and Eddy Transports of Angular Momentum, Water Vapor, and Energy in the Global Atmosphere

Real global data of seven levels (surface pressure, geopotential heights for 700, 500, 300, 200, 100, and 70 mb) analyzed by Baumhefner for the period of 15-19 J anuary 1958 (IGY) are used to evaluate the transports of angular momentum, water vapor, and energy due to mean meridional circulation and eddy motions. Since only mass fields are analyzed, a technique is used to claim the fields of wind and water vapor. With the aid of a six-layer general circulation model developed at the National 'Center for Atmospheric Research (NCAR), short-range forecasts are made from analyzed initial mass fields with geostrophic wind as an initial condition. A climatological zonal mean specific humidity distribution for January is assumed as the initial field for water vapor. It is found that the wind and water vapor fields evolving after 24 hours of time integration appear to be usable for the evaluation of various transport quantities. The computed mean and eddy transports of momentum, water vapor, and energy are compared with those of various observational sources and of a simulated January starting from an isothermal atmosphere with the NCAR general circulation model. It is shown that the values of various transport quantities for the January 1958 case in the Northern Hemisphere are in reasonable agreement with those of other sources. However, the values of transport quantities in the Southern Hemisphere are underestimated due to weak wave activity. The weakness of eddy motions in the Southern Hemisphere is presumably attributed to difficulty in the initial data analysis owing to sparsity of observation stations in the Southern Hemisphere. In this study, we intend to demonstrate that the diagnostic analyses of the mean and eddy transports of various meteorological quantities can be performed from basic data sets with the use of a general circulation model as the means of imposing dynamical constraints among meteorological variables. 573
Multiscale Prototype Contrast Network for High-Resolution Aerial Imagery Semantic Segmentation

Semantic segmentation of high-resolution aerial images is a challenging task on account of complex scene variations and large-scale differences. However, these two issues are inadequately addressed in general semantic segmentation methods. In this article, we propose a multiscale prototype contrast network (MPCNet) to improve the adaptive capability for different scenes and scales. Specifically, a novel multiscale prototype transformer decoder (MPTD) is designed to extract dynamic scene-specific prototypes as pixel classifiers by fusing information from feature maps and learnable class tokens. To exploit cross-scene context information and accommodate the large-scale difference in the aerial image, we build a multiscale prototype memory queue to store these multiscale prototypes during training. Upon the multiscale prototype memory queue, a novel multiscale prototype contrastive loss is proposed to increase object feature discriminability across multiple scales, which brings better consistency of intermediate features and boosts the convergence of the network. Extensive experimental results on three publicly available datasets demonstrate the effectiveness and efficiency of our MPCNet over other state-of-the-art methods. The code is available at https://github.com/qixiong-wang/mmsegmentation-mpcnet.
Cosmic infrared background measurements and star formation history from Planck

Abstract We present new measurements of Cosmic Infrared Background (CIB) anisotropies using Planck. Combining HFI data with IRAS, the angular auto- and cross-frequency power spectrum is measured from 143 to 3000 GHz. After careful removal of the contaminants (cosmic microwave background anisotropies, Galactic dust and Sunyaev-Zeldovich emission), and a complete study of systematics, the CIB power spectrum is measured with unprecedented signal to noise ratio from angular multipoles ℓ ~ 150 to 2500. The interpretation based on the halo model is able to associate star-forming galaxies with dark matter halos and their subhalos, using a parametrized relation between the dust-processed infrared luminosity and (sub-)halo mass, and it allows to simultaneously fit all auto- and cross- power spectra very well. We find that the star formation history is well constrained up to redshifts around 2, and agrees with recent estimates of the obscured star-formation density using Spitzer and Herschel. However, at higher redshift, the accuracy of the star formation history measurement is strongly degraded by the uncertainty in the spectral energy distribution of CIB galaxies. We also find that the mean halo mass which is most efficient at hosting star formation is log(Meff/M⊙) = 12.6 and that CIB galaxies have warmer temperatures as redshift increases.
Psychometric Properties of Online Versions of Mental Toughness Questionnaires in Basketball Players

: The aim of this study was to examine the psychometric properties of using the online version of the questionnaires for assessing mental toughness to gather and analyse the data in scientific research. It was assumed that, with the right introduction, written explanation, and usage of available IT solutions the results will have good psychometric properties. The sample of 79 male athletes that played basketball in a 2022/2023 season, filed online version of the Sports Mental Toughness Questionnaire (SMTQ), the Psychological Performance Inventory - A (PPI–A), and Mental Toughness Inventory (MTI). Results of descriptive analyses showed that good metric characteristics and discriminativeness of all three instruments. Reliability was also confirmed with obtained Cronbach's alpha coefficient scores. Obtained low to high significant positive correlations among all scales and subscales confirmed construct validity of online versions of all three questionnaires for assessing MT. It was concluded that further research of this way of using of measuring instruments is needed but also justify.
Confocal Raman microscopy supported by optical clearing treatment of the skin—influence on collagen hydration

Confocal Raman microscopy (CRM) is employed to study the skin physiology, drug permeation and skin disease monitoring. In order to increase the depth of investigations, the effect of optical clearing was observed on porcine ear skin ex vivo. The optical clearing agents (OCAs) glycerol and iohexol (Omnipaque™) were applied to the porcine ear skin and investigated by CRM after 30 and 60 min of treatment. The extent of optical clearing by utilizing concentrations of 70% glycerol and 100% Omnipaque™ was evaluated. The intensity of the skin-related Raman peaks significantly increased starting from the depth 160 µm for Omnipaque™ and 40 µm for glycerol (p ⩽ 0.05) after 60 min of treatment. The OCAs’ influence on the collagen hydration in the deep-located dermis was investigated. Both OCAs induce skin dehydration, but the effect of glycerol treatment (30 min and 60 min) is stronger. The obtained results demonstrate that with increasing the treatment time, both glycerol and Omnipaque™ solutions improve the optical clearing of porcine skin making the deep-located dermal regions able for investigations. At the used concentrations and time intervals, glycerol is more effective than Omnipaque™. However, Omnipaque™ is more promising than glycerol for future in vivo applications as it is an already approved pharmaceutic substance without any known impact on the skin structure.
Human Activity Recognition With FMCW Radar Using Few-Shot Learning

Frequency-modulated continuous-wave (FMCW) radar-based human activity recognition algorithms often require a large amount of sample data and have a high computational complexity. To address this problem, we propose a learning technique based on few-shot learning using less samples for FMCW radar human activity recognition. The wavelet transform and background frame differences processing on recorded human activity signals are first leveraged to obtain noise-reduced and frame-calibrated data, and then, the 2-D Fourier transform is applied to construct a range-Doppler map (RDM). Next, the maps were stitched together frame by frame along the velocity dimension to form micro-Doppler signatures (m-D signatures), which are used for feature extractions of different human activities. Finally, these m-D signatures are put into a designed residual block prototypical networks for training and classification. The experimental results show that our method is less computationally complex and more generalizable, with an average recognition accuracy of 98.33% for eight human activities with only 30 training samples.
Study of the Interaction Processes in Cuprate Superconductors by a Quantitative Comparison of Spectroscopic Experiments

Inelastic light scattering is applied to systematically study the doping-, temperature- and momentum-dependent electron dynamics of hole- and electron-doped cuprates. The study aims at a better understanding of the normal state interaction processes in the cuprates. The focus is thereby placed on the strongly overdoped regime, where conventional quasiparticle behavior seems to prevail, down to optimal doping, where strong correlations leave traces in essentially all observables.

IL-18 in Autoinflammatory Diseases: Focus on Adult Onset Still Disease and Macrophages Activation Syndrome

Interleukin-18 (IL-18) is a potent pro-inflammatory cytokine that is involved in various innate and adaptive immune processes related to infection, inflammation, and autoimmunity. Therefore, it is described as a key mediator of autoinflammatory diseases associated with the development of macrophage activation syndrome (MAS), including systemic juvenile idiopathic arthritis and adult-onset Still’s disease. This review focuses on the role of IL-18 in inflammatory responses, placing emphasis on autoinflammatory diseases associated with chronic excess of serum IL-18, which correlate with clinical and biological signs of the disease. Therefore, it is useful for the diagnosis and monitoring of disease activity. Researchers are currently investigating IL-18’s role as a therapeutic target for the treatment of inflammatory diseases. The inhibition of IL-18 signaling through recombinant human IL-18BP (IL-18 binding protein) seems to be an effective therapeutic strategy, though further studies are necessary to clarify its importance as a therapeutic target.

How Financial Distress Affect The Coping Strategy? Case Of Indonesian MSME’s During The Covid-19 Outbreak

This research intends to examine the effect of financial distress, self-efficacy, and leadership skills on coping strategy in time of COVID-19 pandemic. This study focuses on the coping strategy implementation of MSMEs in Indonesia during economic downturn due to the pandemic. We examine 125 MSMEs in Indonesia as our respondents. We employ multinomial logistics regression technique to test the hypotheses. Our findings show that financial distress negatively affects the choice of coping strategy. On the other hand, self-efficacy and leadership skills have a positive impact on coping strategy. Financial distress, self-efficacy, and leadership skills are empirically proven as the determinant factors that influence the coping strategy selection process during the COVID-19 pandemic. This research uses a new perspective of financial distress scales and leadership skills aspects as a new insight in coping strategy decision making process. This study contributes to the development literature on coping strategy and its determinant factors during crisis conditions. practically, this research has implications to the development of coping strategy models and its influenced factors for business practitioners, especially on how to develop coping models during crisis condition.

Potential irradiation of Cu alloys and tungsten samples in DONES

Tungsten and Cu alloys are currently proposed as reference candidate material for ITER and DEMO first wall and divertor. Tungsten is proposed for its high fusion temperature and CuCrZr alloys for their high thermal conductivity together with good mechanical properties. However its behaviour under the extreme irradiation conditions as expected in ITER or DEMO fusion reactors is still unknown. Due to the determinant role of H and He played in the material behaviour any irradiation experiment must take into account the amount of these gases produced during the irradiation in Fusion reactors with high-energy neutrons. DONES (DEMO oriented neutron source) has been conceived as a simplified IFMIF (International Fusion Material Irradiation Facility) like plant to provide in a reduced time scale and with a reduced budget—both compared to IFMIF—the basic information on materials damage. The objective of DONES-IFMIF in its first stage will be to test structural materials under similar neutron irradiation nuclear fusion conditions as expected in fusion reactors. These tests will be carried out with specimens irradiated in the so called high flux test module (HFTM). The objective of this paper is to assess on the potential use of DONES to irradiate copper (Cu) alloys and tungsten (W) in the HFTM together with reduced activation ferritic martensitic steel like for example EUROFER (9%-Cr-steel). The presence of Cu alloys or W specimens may have an effect in the irradiation parameters of the EUROFER samples placed also in the HFTM and in the samples of the creep fatigue test module (CFTM). McDeLicious code is used for neutron transport calculations. Damage dose rate and H and He production are analysed in the different locations and compared with the irradiation conditions in first wall and divertor in fusion machines.
