A New Optimized IPMSM for EVs With Reduced Magnet Loss for Over-Modulation Operation

In the traction motor drives of electric vehicle applications, the over-modulation strategy is usually implemented to enhance the output torque capability of the interior permanent magnet synchronous motor (IPMSM), so that the dc input voltage of the inverters can be fully utilized by operating the inverter up to the six-step mode. However, it will inevitably introduce rich harmonic components into phase current, leading to the worsening issue of magnet eddy-current loss (MECL). Therefore, a new hybrid magnet rotor structure for fractional-slot concentrated-winding IPMSM with optimum design for magnet loss reduction is employed with the vital improvement measures concluded as follows: first, high-resistivity ferrite magnets are introduced in the rotor flux paths of the <inline-formula> <tex-math notation="LaTeX">$d$ </tex-math></inline-formula>-axis and <inline-formula> <tex-math notation="LaTeX">$q$ </tex-math></inline-formula>-axis, respectively, to form a hybrid magnets rotor structure together with Nd–Fe–B magnets; second, a rotor structure is proposed by employing a V-type placement of Nd–Fe–B magnets in the <inline-formula> <tex-math notation="LaTeX">$d$ </tex-math></inline-formula>-axis path with the angle of V-type as one of the critical optimization parameters. An optimized design is finally obtained by employing the multi-objective genetic algorithm optimizer in JMAG finite element analysis tools, which is tested to show that the MECL produced in the over-modulation operation can be significantly suppressed by the optimized design.
Detecting Majorana fermions in quasi-one-dimensional topological phases using nonlocal order parameters

Topological phases which host Majorana fermions can not be identified via local order parameters. We give simple nonlocal order parameters to distinguish quasi-one-dimensional (1D) topological superconductors of spinless fermions, for any interacting model in the absence of time reversal symmetry. These string or "brane" order parameters are natural for measurements in cold atom systems using quantum gas microscopy. We propose them as a way to identify symmetry-protected topological phases of Majorana fermions in cold atom experiments via bulk rather than edge degrees of freedom. Subsequently, we study two-dimensional (2D) topological superconductors via the quasi-1D limit of coupling $N$ identical chains on the cylinder. We classify the symmetric, interacting topological phases protected by the additional $\mathbb{Z}_N$ translation symmetry. The phases include quasi-1D analogs of (i) the $p+ip$ chiral topological superconductor, which can be distinguished up to the 2D Chern number mod 2, and (ii) the 2D weak topological superconductor. We devise general rules for constructing nonlocal order parameters which distinguish the phases. These rules encode the signature of the fermionic topological phase in the symmetry properties of the terminating operators of the nonlocal string or brane. The nonlocal order parameters for some of these phases simply involve a product of the string order parameters for the individual chains. Finally, we give a physical picture of one of the topological phases as a condensate of certain defects, which motivates the form of the nonlocal order parameter and is reminiscent of higher dimensional constructions of topological phases.
Relation between nonlocality and contextuality for a biphoton

We investigate the set of qutrit states in terms of symmetric states of two qubits that violate the minimal contextual inequality, namely the Klyachko-Can-Binicoglu-Shumovsky (KCBS) inequality. The physical system that provides a natural framework for this problem is a biphoton, which consists of two photons in the same spatiotemporal mode and whose effective polarization behaves as a three-level quantum system. The relationship between the KCBS contextual inequality and the Clauser-Horne-Shimony-Holt (CHSH) inequality is investigated. We find that every biphotonic state that is contextual with respect to KCBS is nonlocal as per the CHSH test when the two photons are apart, but the converse is not true.
IGR J16318-4848 & CO: A NEW POPULATION OF HIDDEN HIGH-MASS X-RAY BINARIES IN THE NORMA ARM OF THE GALAXY

IGR J16318-4848 was discovered by INTEGRAL on January 29, 2003 and regularly observed during the galactic scans of the INTEGRAL core program and during private observations. XMM observations of the source indicate that the high-energy source is highly absorbed by local cold matter. Infrared spectroscopy did show that the source counterpart is most probably a blue super-giant that features a dense cold stellar wind component. The soft γ-ray energy continuum of IGR J16318-4848 shows a cutoff at 40 keV and has been constantly variable by a factor of at least 20. Its spectral shape appears to be independent of the source level. Cutoffs in this energy range are most often associated with systems containing neutron stars. We suggest that the hard X-ray variability is related to accretion disk instabilities. The accretion disk refills when the neutron stars interact with the stellar wind that is also responsible for the huge absorption. In addition to IGR J16318-4848, INTEGRAL discovered 8 new sources in the Norma arm tangent region of the Galaxy. All the sources that have been further studied do show strong absorption. These sources could be a new family of high-mass X-ray binaries with cold dense stellar winds. Their high density in the Normal arm, the region of the Galaxy with the highest massive star-formation rate, probably indicate that dense and cold stellar winds favor accretion in X-ray binaries.
ISLAMIC EDUCATION PROBLEMS AND THEIR SOLUTIONS (QUALITY OF PAI TEACHERS)

The reality of Islamic Religious Education is that many problems still occur in schools today. Islamic Religious Education is often considered a boring subject and learning activity. Many factors can cause this, including the unprofessionalism of a PAI teacher or students who are less enthusiastic about studying religious knowledge. So, this study aims to find the problems of Islamic education and its solutions, especially in the quality of Islamic Religious Education teachers. The research method used is library research. The research results are that currently, the teacher is the bearer of the educational mission whose job is to teach based on specific scientific and academic qualities. Then, get material rewards from the state and or other education management parties in which the compensation is not by the energy expended. Several solutions can encourage efforts to improve the problems of these educators, namely (1) increased teacher work discipline and implementation of good learned plans through coached, trained, and workshops. (2) the government and the foundation where teachers serve should pay attention to the welfare of teachers, (3) teachers should study and practice to improve their abilities (4) PAI teachers should be teachers who have met the qualifications
Repair Foci as Liquid Phase Separation: Evidence and Limitations

In response to DNA double strand breaks (DSB), repair proteins accumulate at damaged sites, forming membrane-less condensates or “foci”. The formation of these foci and their disassembly within the proper time window are essential for genome integrity. However, how these membrane-less sub-compartments are formed, maintained and disassembled remains unclear. Recently, several studies across different model organisms proposed that DNA repair foci form via liquid phase separation. In this review, we discuss the current research investigating the physical nature of repair foci. First, we present the different models of condensates proposed in the literature, highlighting the criteria to differentiate them. Second, we discuss evidence of liquid phase separation at DNA repair sites and the limitations of this model to fully describe structures formed in response to DNA damage. Finally, we discuss the origin and possible function of liquid phase separation for DNA repair processes.
Imaging of four Galactic supernova remnants in the mid-infrared, and their interaction with the interstellar medium

We provide mid-infrared (MIR) imaging, photometry and profiles for the Galactic supernova remnants (SNRs) G001.0-00.1, G355.9-02.5, G355.6-00.0 and W28 based upon data deriving for the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE). All of the sources show evidence for interaction with the interstellar medium (ISM), leading to curved frontal structures and apparent voids in the ISM. An analysis of the spectral energy distributions (SEDs) of Class I young stellar objects (YSOs) within the north-westerly interaction region of W28, and of the density of stars within the borders of the SNR, suggests that many of them may have been triggered by the SN event. 2D radiative transfer modelling permits us to constrain the physical parameters of the sources. It is also noted that the location of Class I YSOs about the perimeter of G001.0-00.1, and close to frontal arcs associated with SNR G355.9-02.5, suggests that star formation may have been triggered by these SNRs as well. Finally, it is found that the MIR colours of the frontal structures appear consistent with shock excitation of the υ = 0 → 0 transitions of H 2 , although it is conceivable that emission by polycyclic aromatic hydrocarbons (PAHs) may also play a role. Where the latter mechanism is relevant, it is possible that emission derives from the shattering of larger grains in frontal regions, leading to increased volume densities of PAH carrying grains.
Turbulence-resilient pilot-assisted self-coherent free-space optical communications using a photodetector array for bandwidth enhancement.

We experimentally demonstrate a 4-Gbit/s 16-QAM pilot-assisted, self-coherent, and turbulence-resilient free-space optical link using a photodetector (PD) array. The turbulence resilience is enabled by the efficient optoelectronic mixing of the data and pilot beams in a free-space-coupled receiver, which can automatically compensate for turbulence-induced modal coupling to recover the data's amplitude and phase. For this approach, a sufficient PD area might be needed to collect the beams while the bandwidth of a single larger PD could be limited. In this work, we use an array of smaller PDs instead of a single larger PD to overcome the beam collection and bandwidth response trade-off. In the PD-array-based receiver, the data and pilot beams are efficiently mixed in the aggregated PD area formed by four PDs, and the four mixing outputs are electrically combined for data recovery. The results show that: (i) either with or without turbulence effects (D/r0 = ∼8.4), the 1-Gbaud 16-QAM signal recovered by the PD array has a lower error vector magnitude than that of a single larger PD; (ii) for 100 turbulence realizations, the pilot-assisted PD-array receiver recovers 1-Gbaud 16-QAM data with a bit-error rate below 7% of the forward error correction limit; and (iii) for 1000 turbulence realizations, the average electrical mixing power loss of a single smaller PD, a single larger PD, and a PD array is ∼5.5 dB, ∼1.2 dB, and ∼1.6 dB, respectively.
Study of Histopathological Changes in the Placenta in Preeclampsia

Pregnancy disorders include, most commonly, hypertensive disorders, which include gestational hypertension, preeclampsia, and chronic hypertension with superimposed preeclampsia. Various etiological factors prove to be both risks as well as protective factors, which include genetic factors, maternal smoking (it is inversely related to preeclampsia; that is, smoking decreases the incidence of preeclampsia), and other medical comorbidities such as hypertension, diabetes, asthma, and others, including older maternal age and high body mass index. Usually, high maternal and fetal mortality rates are seen with the diagnosis of hypertensive disorders in pregnancy, and severe morbidity is seen in cases of preeclampsia, eclampsia, and HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet count), along with raised levels of liver enzymes and blood disorders such as low platelet counts. Preeclampsia is considered one of the most serious consequences of pregnancy. These disorders are often presented as newly diagnosed high blood pressure and proteinuria during the last trimester. But it can prove to be fatal for both the mother and the fetus. Though the causative factors of preeclampsia are still unknown, specific clinical and histopathological researchers propose that preeclampsia can be due to pathological changes in the placenta. The basic aim of this article is to discuss various histopathological changes in the placenta due to preeclampsia, but minor topics that affect the pathophysiology of the placenta due to preeclampsia are also mentioned. Furthermore, the effective management of maternal syndrome complications in pregnancy has also been discussed.
Multiple Sequence Long and Short Memory Network Model for Corner Gas Concentration Prediction on Coal Mine Workings

To further improve the accuracy of recurrent neural network in predicting the gas concentration in the upper corner of the mine tunnel, this paper proposes a method to construct a gas concentration prediction model based on multiple sequence long and short memory network, considering the spatial correlation between the gas concentration in the return airway and upper corner. The reliability of the model construction is improved by using the white noise test and smoothness test to verify the interpretability of the data in this paper and constructing supervised learning type data for gas concentration prediction model training and testing by means of data set division and data windowing. Through experimental comparison, grid search, and time series decomposition, the model algorithm, training parameters, and experimental results were combined to make an in-depth analysis of the influence of each parameter on the model training and the prediction. A training model of the spatially fused gas concentration prediction model with a network layer of 1 and a number of neurons of 32 as the model structure, Adam as the optimization algorithm, and a learning rate of 0.001 and a batch size of 32 as the training parameters was finally determined. The gas concentration prediction model trained in this paper performed well in the test set with a mean square error (MSE) of 0.0013, and its superiority was verified by comparing it with other models to provide some experience and basis for subsequent studies on gas concentration prediction in the upper corner.
Elastic and inelastic breakup of deuterons with energy below 100 MeV

We present calculations of deuteron elastic and inelastic breakup cross sections and angular distributions at deuteron energies below 100 MeV obtained using the post-form DWBA approximation. The elastic breakup cross section was extensively studied in the past. Very few calculations of inelastic breakup have been performed, however. We also analyze the angular momentum - energy distributions of the cross section for formation of the compound nucleus after inelastic breakup.
Hot-Melt and Pressure-Sensitive Adhesives Based on Styrene-Isoprene-Styrene Triblock Copolymer, Asphaltene/Resin Blend and Naphthenic Oil

Asphaltene/resin blend (ARB) extracted from heavy crude oil was used to modify poly(styrene-block-isoprene-block-styrene) (SIS) to make it an adhesive. There were prepared double and triple mixtures containing 10–60% SIS, 10–40% ARB, and 10–50% naphthenic oil used as an additional plasticizer. The viscoelasticity of the mixtures at 25 °C and 120 °C was studied, their flow curves were obtained, and the temperature dependences of the loss tangent and the components of the complex modulus were measured. In addition, the mixtures were used as hot-melt adhesives (HMAs) and pressure-sensitive adhesives (PSAs) in the shear, peel, and pull-off tests of the adhesive bonds that they formed with steel. Both naphthenic oil and ARB act as plasticizers for SIS and make it sticky. However, only the combined use of ARB and the oil allows for achieving the best set of adhesive properties of the SIS-based mixture. High-quality HMA requires low oil content (optimal SIS/ARB/oil ratio is 50/40/10, pull-off adhesion strength (τt) of 1990 kPa), whereas a lot of the oil is needed to give SIS characteristics of a PSA (SIS/ARB/oil is 20/40/40, τt of 100 kPa). At the same time, the resulting PSA can be used as a hot-melt pressure-sensitive adhesive (HMPSA) that has many times lower viscosity than HMA (13.9 Pa·s versus 2640 Pa·s at 120 °C and 1 s−1) but provides a less strong adhesive bond (τt of 960 kPa).
The Effect of Dietary Supplementations on Delaying the Progression of Age-Related Macular Degeneration: A Systematic Review and Meta-Analysis

Purpose: Age-related macular degeneration (AMD) is a neurodegenerative ophthalmic disease. The purpose of this systematic review (SR) and meta-analysis was to evaluate if dietary supplementation alone or in combinations might delay the progression of any of the stages of AMD. Methods: A SR and meta-analysis identifying cohort studies and randomized controlled trials (RCTs) evaluating the effect of supplements in patients diagnosed with AMD. PubMed, Scopus, Web of Science, CINAHL, and Cochrane were searched through 8th October 2021. Results: Twenty studies, examining 5634 participants ranging from 55 to 80 years, were included in the SR. Eight studies were selected for meta-analysis (414 and 216 subjects in the intervention and control groups). Lutein and zeaxanthin plus n-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) supplementation showed significant improvements in best-corrected visual acuity (BCVA) (SMD: −1.99, 95% CI: −3.33, −0.65) compared to the control group. Multifocal electroretinogram results (mfERG) were significantly improved overall (SMD: 4.59, 95% CI: 1.75, 7.43) after lutein plus zeaxanthin supplementation. Conclusions: Combinations of lutein and zeaxanthin with n-3 LC-PUFA might be beneficial in preventing AMD progression and deterioration of visual function. Our results encourage initiating further studies with combinations of n-3 LC-PUFA, lutein, and zeaxanthin especially in early AMD patients.
Lateral Canthotomy and Cantholysis for Spontaneous Retrobulbar Hemorrhage With Normal Intraocular Pressures: Case Report and Review of the Literature

Spontaneous retrobulbar hemorrhage (RBH) is uncommon and typically occurs secondary to vascular malformations, coagulopathies, hypertension, or strenuous activities in the setting of elevated intraocular pressure (IOP). RBH can cause orbital compartment syndrome (OCS) with resultant permanent vision loss. We present a case of spontaneous RBH in an 18-year-old male with a history of acute lymphoblastic leukemia (ALL) and sepsis. While IOPs were normal, the patient exhibited symptoms of OCS in which a lateral canthotomy and cantholysis were performed. This case highlights the importance of the clinical exam when treating a patient with suspected OCS and demonstrates that intraocular pressures need not be elevated for both diagnosis and intervention.
Prognostic impact of cerebral embolism in patients with active infective endocarditis and therapeutic strategies. A retrospective real world study in a surgical centre

Infective endocarditis still has high mortality and invalidating complications, such as cerebral embolism. The best strategies to prevent and to manage neurologic complications remain uncertain. This study aimed to identify predictors of septic cerebral embolism and to evaluate the role of surgery in these patients, in a real-world surgical center. We retrospectively analyzed 551 consecutive patients admitted to our department with a definite diagnosis of non-device-related infective endocarditis; of these, 126 (23%) presented a neurologic complication. Cerebral embolism was significantly more frequent in patients with large vegetations (p=0.001), mitral valve infection (p=0.001), and Staphylococcus aureus infection (p=0.025). At multivariable analysis, only vegetation length was an independent predictor of cerebral embolism (HR 1.057, 95% CI 1.025–1.091, p 0.001), with a best predictive threshold of 10 mm at ROC curve analysis (AUC 0.54, p=0.001). Patients with neurologic complications were more often excluded from surgery despite an indication to it (16% vs 8%, p=0.001). If eligible, they were treated within two weeks from diagnosis in similar proportion as patients without cerebral embolism with similar survival rate. Predictors of mortality were hemorrhagic lesions (p=0.018), a GCS<14 (p=0.001) or a severe degree of disability (p=0.001) at presentation. The latter was the only independent predictor of mortality at multivariable analysis (HR 2.3, 95% CI 1.43–3.80, p=0.001). The present study highlights the prognostic value of clinical functional presentation and the safety of cardiac surgery, when feasible, in patients with septic cerebral embolism. Type of funding sources: None.
Semaglutide in Overweight and Obese patients: Cardiovascular and/or Renal Metabolic Benefits

We have read the article published by Kadowaki, et al. 1 “Semaglutide once a week in adults with overweight or obesity, with or without type 2 diabetes mellitus in an East Asian population (STEP 6): A randomized, double blind, double dummy, placebo controlled, phase 3a trial”, where the authors conclude that semaglutide at a dose of 2.4 mg, in diabetic and non-diabetic patients, reduces obesity and overweight compared to placebo in East Asian patients. These interesting results, demonstrate once again its benefits regarding overweight and obesity1,2. We consider that there should be several relevant aspects to have in mind. The study shows, once again, that semaglutide might have dose dependent effects and some that aren’t dose dependent, with weight loss being a dose-dependent effect. Regarding renal benefits, we consider that including albuminuria as a variable is of importance, given that only eGFR by CKD-EPI was included in the study. The average eGFR of the patients was 97.2 cc/min, patients with an eGFR less than 30 were excluded (eGFR less than 60 in patients receiving SGLT-2 inhibitors). We mention this since it would’ve been interesting to evaluate albuminuric vs non-albuminuric patients, hence seeing if there are any renal benefits, especially in albuminuric patients that may be dose dependent. Recently, Shaman, et al. 3 reported that liraglutide and semaglutide had renal benefits in type 2 diabetes mellitus, but their effect in albuminuria was higher in patients with 1 mg of semaglutide weekly vs 0.5 mg weekly. The latter allows to hypothesize that this effect may be dose dependent. Given this, it would be of interest to assess if higher doses bring increased renal benefits, as seen in weight loss. In summary, having in mind the renal benefits seen by semaglutide in other studies4, it would be of great importance to verify the impact of albuminuria in patients with obesity. Hence, we hope that in the upcoming trials, albuminuria is taken into consideration, so that we can highlight not only the cardio-metabolic benefits, but renal benefits in diabetic and non-diabetic patients that are obese or overweight, and to assess if there is a dose-dependent response.
