Research on Rolling Bearing Fault Diagnosis Method Based on Generative Adversarial and Transfer Learning

The diagnosis of rolling bearing faults has become an increasingly popular research topic in recent years. However, many studies have been conducted based on sufficient training data. In the real industrial scene, there are some problems in bearing fault diagnosis, including the imbalanced ratio of normal and failure data and the amount of unlabeled data being far more than the amount of marked data. This paper presents a rolling bearing fault diagnosis method suitable for different working conditions based on simulating the real industrial scene. Firstly, the dataset is divided into the source and target domains, and the signals are transformed into pictures by continuous wavelet transform. Secondly, Wasserstein Generative Adversarial Nets-Gradient Penalty (WGAN-GP) is used to generate false sample images; then, the source domain and target domain data are input into the migration learning network with Resnet50 as the backbone for processing to extract similar features. Multi-Kernel Maximum mean discrepancies (MK-MMD) are used to reduce the edge distribution difference between the data of the source domain and the target domain. Based on Case Western Reserve University′s dataset, the feasibility of the proposed method is verified by experiments. The experimental results show that the average fault diagnosis accuracy can reach 96.58%.
Regret Theory-Based Three-Way Decision Method on Incomplete Multiscale Decision Information Systems With Interval Fuzzy Numbers

In realistic decision-making environments, human behaviors bring influences to various decision-making procedures, and classic multiattribute decision-making approaches based on utility decisions own some deviations from actual situations. The behavioral decision theory modifies classic decision-making theories to make the new method more applicable. Regret theory, as one of the important components in behavioral decision theories, has been widely used in theories and applications. Based on regret theory, we establish a generalized three-way decision method on incomplete multiscale decision information systems with interval fuzzy numbers. First, we select an incomplete optimal subsystem for the incomplete multiscale information system, and convert the multiscale evaluation information into an interval fuzzy number by using a linguistic term set. Second, based on the probability distribution of evaluation values and tradeoff factors, we propose a target-dependent approximation estimation method for the incomplete interval fuzzy subsystem. Then, the regret–rejoicing preferences between objects are obtained. Finally, a tripartition and ranking method based on a max-bipartition and preference index is established. Moreover, the incompleteness experiments show that the decision-making results of our method can still maintain more than 97% consistency in an incomplete information system with a missing rate of at most 20%. In addition, the parameter analysis shows that the proposed method maintains an accuracy rate of more than 98% and a classification error rate of no more than 0.6%.
Genome-Wide Analysis of Glycoside Hydrolase Family 1 β-glucosidase Genes in Brassica rapa and Their Potential Role in Pollen Development

Glycoside hydrolase family 1 (GH1) β-glucosidases (BGLUs) are encoded by a large number of genes, and are involved in many developmental processes and stress responses in plants. Due to their importance in plant growth and development, genome-wide analyses have been conducted in model plants (Arabidopsis and rice) and maize, but not in Brassica species, which are important vegetable crops. In this study, we systematically analyzed B. rapa BGLUs (BrBGLUs), and demonstrated the involvement of several genes in pollen development. Sixty-four BrBGLUs were identified in Brassica databases, which were anchored onto 10 chromosomes, with 10 tandem duplications. Phylogenetic analysis revealed that 64 genes were classified into 10 subgroups, and each subgroup had relatively conserved intron/exon structures. Clustering with Arabidopsis BGLUs (AtBGLUs) facilitated the identification of several important subgroups for flavonoid metabolism, the production of glucosinolates, the regulation of abscisic acid (ABA) levels, and other defense-related compounds. At least six BrBGLUs might be involved in pollen development. The expression of BrBGLU10/AtBGLU20, the analysis of co-expressed genes, and the examination of knocked down Arabidopsis plants strongly suggests that BrBGLU10/AtBGLU20 has an indispensable function in pollen development. The results that are obtained from this study may provide valuable information for the further understanding of β-glucosidase function and Brassica breeding, for nutraceuticals-rich Brassica crops.
A Millimeter-Wave Ultrawideband Tightly Coupled Dipole Array Antenna for Vehicle Communication

This letter presents a millimeter-wave (mmWave) ultrawideband tightly coupled dipole array (TCDA) for vehicle communication. The designed array antenna has eight dipole unit cells arranged in one dimension. A special Marchand balun with comb-type perforated structure is developed to realize the unbalance-to-balance transformation and match the impedance. The proposed unit cell of the array achieves a 1:7.6 bandwidth (5.7 GHz--43.3 GHz) with active reflection coefficient less than −6 dB during the simulation. Meanwhile, the antenna achieves a low profile of 0.087 λl, where λl is the free-space wavelength at the lower cut-off frequency. Then, a prototype with scanning angle up to 45° is fabricated and measured to validate the proposed structure. The measured realized gain of the array is 8 dBi at the center frequency of 18 GHz. The measured and simulated results are in good agreement, which confirms the simulation results and validate the proposed design.
Linear-Phase Octave Graphic Equalizer

A computationally efficient octave-band graphic equalizer having a linear-phase response is introduced. The linear-phase graphic equalizer is useful in audio applications in which phase distortion is not tolerated, such as in multichannel equalization, parallel processing, phase compatibility of audio equipment, and crossover network design. The structure is based on the interpolated finite impulse response (IFIR) philosophy. The proposed octave-band graphic equalizer uses one prototype low-pass filter, which is a half-band FIR filter designed using the window method. Stretched versions of the prototype filter and its complementary high-pass filter implement all ten band filters needed. The graphic equalizer is realized in the parallel form, in which the outputs of all band filters, scaled with their individual command gain, are added to compute the equalized output signal. The command gains can be used directly as filter band gains. The number of operations needed per sample is only slightly more than that needed for the graphic equalizer based on minimum-phase recursive filters. A comparison with other implementation approaches demonstrates that the proposed structure requires 99% fewer operations than a high-order FIR filter. The proposed filter uses 39% fewer operations per sample than the fast Fourier transform–based filtering method and causes over 78% less latency.

HIV-AIDS mengakibatkan penurunan sistem imun tubuh dan terjadinya inflamasi yang berpengaruh pada kualitas hidup pasien. Kadar IL-10 dapat dikaitkan juga sebagai respon terhadap adanya inflamasi yang akan mempengaruhi kualitas hidup pasien HIV-AIDS. Penelitian ini bertujuan mengukur kadar IL-10 serum pasien, menentukan kualitas hidup pasien berdasarkan skor WHOQOL dan menganalisis korelasi kadar IL-10 serum dengan kualitas hidup pasien HIV-AIDS. Desain penelitian ini adalah potong lintang dengan rancangan uji korelasi, dilakukan pada Juni-Oktober 2020 di RSMH Palembang dengan subjek penelitian pasien yang didiagnosis HIV-AIDS dalam pengobatan rutin di Poliklinik Tropik dan Infeksi Penyakit Dalam RSMH Palembang. Sampel diperoleh dengan metode consecutive sampling pasien yang mengkonsumsi obat anti retroviral (ARV) dan berusia ≥ 18 tahun. Seluruh pengolahan dan analisis data dalam penelitian ini dengan menggunakan Program SPSS versi 22 for Windows.Dari sampel sebanyak 32 pasien didapatkan Kadar IL-10 serum pasien HIV-AIDS dengan median 0,41 pg/ml, nilai minimum 0,14 pg/ml; dan nilai maksimum 5,41 pg/ml. Sebanyak 20 orang (62.5%) memiliki kualitas hidup baik, sedangkan 12 orang (37.5%) memiliki kualitas hidup buruk. Berdasarkan hasil analisis multivariat didapatkan interpretasi bahwa semakin lama mengkonsumsi ARV dan semakin rendah kadar IL-10 secara simultan, maka kualitas hidup akan semakin baik dengan kekuatan korelasi kuat (r= 0.673). Kadar IL-10 serum berkorelasi negatif dengan kualitas hidup pasien HIV-AIDS dengan kekuatan korelasi kuat (r= -0,641). Dengan demikian kadar IL-10 serum dapat dijadikan prediktor kualitas hidup pasien HIV-AIDS
miR-505-5p alleviates acute rejection of liver transplantation by inhibiting Myd88 and inducing M2 polarizationof Kupffer cells

The occurrence of acute rejection after liver transplantation seriously impairs the prognosis of patients. miRNA is involved in many physiological and pathological processes of the body, but the mechanism of miRNA action in liver transplantation is not completely clear. In this study, we discuss the role of miR-505-5p in acute rejection after liver transplantation and its putative regulating mechanism. We construct an allogeneic rat liver transplantation model, observe the morphological and pathological changes in liver tissue, detect the expression levels of Myd88, miR-505-5p, IL-10 and TNF-α, and confirm that Myd88 is one of the direct targets of miR-505. The effects of miR-505-5p on the Myd88/TRAF6/NF-κB and MAPK pathways are detected both in vitro and in vivo, and the standard markers of Kupffer cell M1/M2 polarization are also detected. The results of qRT-PCR experiments show that miR-505-5p has a downward trend in rats with acute rejection. Western blot analysis reveals that over-expression of miR-505-5p induces the reduction of NF-κB and MAPK pathways both in vitro and in vivo. The role of miR-505-5p in alleviating acute rejection after transplantation may be accomplished by inducing M2-type polarization of Kupffer cells. In conclusion, we find that miR-505-5p alleviates acute rejection of liver transplantation by inducing M2 polarization of macrophages via the Myd88/TRAF6 axis, which suggests a potential strategy based on miRNAs in the follow-up treatment of liver transplantation.

Management of Atopic Dermatitis in Adults in Saudi Arabia: Consensus Recommendations from the Dermatological Expert Group

Background Atopic dermatitis (AD) is a long-term, pruritic, recurrent, systemic, inflammatory skin disorder. In the Middle East region, the burden of AD is understudied, and there is a dearth of AD guideline documents for practitioners. Methods An expert panel meeting, encompassing 12 dermatologists from the Kingdom of Saudi Arabia (KSA), was congregated to develop evidence- and experience-based consensus recommendations for AD management, especially in adults in KSA. They completed a questionnaire with seven clinical statements, and a consensus was defined when the responses of ≥75% of participants coincided. Results The expert recommendations were as follows: American Association of Dermatology guidelines are to be followed for defining AD; Eczema Area and Severity Index or SCORing atopic dermatitis index may be used to quantify the disease severity; Dermatology Life Quality Index may be used to determine the impact of AD on patients’ quality of life; Atopic Dermatitis Control Tool may be used to assess long-term disease control in AD patients; and the European guidelines are to be followed for the management of AD. In AD patients who are inadequately controlled with topical or systemic therapies, the preferred systemic agent for use either alone or in combination with topical treatments is dupilumab, cyclosporine, methotrexate, phototherapy, or other available systemic treatments that may include mycophenolate mofetil or oral corticosteroids. Conclusion These expert recommendations assist physicians by providing a reference framework for optimal care of adult AD patients.

Contactless Palmprint Recognition System: A Survey

Information systems in organizations traditionally require users to remember their secret pins or (passwords), token, card number, or both to confirm their identities. However, the technological trend has been moving towards personal identification based on individual behavioural attributes (such as gaits, signature, and voice) or physiological attributes (such as palmprint, fingerprint, face, iris, or ear). These attributes (biometrics) offer many advantages over knowledge and possession-based approaches. For example, palmprint images have rich, unique features for reliable human identification, and it has received significant attention due to their stability, reliability, uniqueness, and non-intrusiveness. This paper provides an overview and evaluation of contactless palmprint recognition system, the state-of-the-art performance of existing studies, different types of “Region of Interest” (ROI) extraction algorithms, feature extraction, and matching algorithms. Finally, the findings obtained are presented and discussed.
The Beaming of Radiation from an Accreting Magnetic Neutron Star and the X-ray Pulsars

As a result of accretion, a neutron star with a strong magnetic field H ~ 10/sub 10/ to 10/sup 12/ Gauss may exhibit characteristics of an x-ray pulsar with a knife radiation pattern. The infalling gas is channeled to the magnetic pole regions where its kinetic energy is released as it strikes the star surface. The cyclotron radiation at high gyrofrequency harmonics (lying in the x-ray range) determines the rate of energy removal from the hot plasma (kT/sub e~/ 10 to 100 keV). The net harmonic radiation spectrum resembles the spectrum of bremsstrahlung radiation from an optically thin plasma, but with a lower temperature. Radiation at high harmonics is characterized by a strong beaming prpendicular to the magnetic field lines of force. However the situation is also possible, when the radiating electrons are relativistic and move at small pitch angles to the magnetic field. In this case the Doppler-shifted cyclotron radiation at nu << &nn/sub H/ is directed along magnetic field, forming the pencil diagram. ( auth)
Ring-pull Type Soft Wearable Robotic Glove for Hand Strength Assistance

This letter proposes and verifies a new method, the ring-pull mechanism, to overcome the disadvantages of existing wearable robotic gloves. By attaching a ring to the metacarpopha-langeal joint of the finger, the ring-pull mechanism supplements the grasping force of the user, while reducing the weight of the entire wearable robotic glove system. Ring-pull mechanism experiments were conducted to determine which finger combinations had the most positive effect on muscle strength assistance, and through this, the Ring-Pull type Soft Glove (RPSG) was developed. The main body of the developed RPSG is composed of single polymer silicon, a soft material, and is driven by tendon-driven actuation. The tendon path is secured through a tube attached to the palm that matches the direction of the flexor digitorum superficialis (FDS). The new type of wearable robotic glove was manufactured with the proposed mechanism, and excellent fit and strength support effects were confirmed. The RPSG increased the subject's grasping force by 25.69% on average, and the %MVIC data analysis demonstrated that the activation of FDS decreased by about 23.51%. As a result, it was confirmed that the user's muscle efficiency was increased due to the muscle support and muscle function improvement provided by the RPSG.
Comparison of 2- and 3-Minute Inter-Repetition Rest Periods on Maximal Jerk Technique and Power Maintenance

ABSTRACT Purpose: The aim of this study was to examine the effect of 3- vs. 2-minute inter maximal-repetition rest period (IMRRP) on maintaining jerk technical efficiency and power production during two successive maximal repetitions of Clean & Jerk (C&J). Methods: In a randomized, within subject, repeated measures design, nine elite-weightlifters (age: 24.4 ± 3.6 years, body mass: 77.2 ± 7.1 kg, height 176.0 ± 6.4 cm and 1RM C&J: 170.0 ± 5.0 kg) performed 2-separate testing sessions using 2 (IMRRP-2) and 3 (IMRRP-3) -minute IMRRP, while barbell kinematics and kinetics and joint kinematics were recorded. Results: Statistical analysis showed that one minute longer IMRRP enhanced the maintenance of optimal jerk technique evidenced by reducing declines in peak vertical barbell displacement (2.74%; p = .03), peak barbell velocity (2.89%; p = .03), and peak knee (1.61%; p = .03) and hip extensions (1.59%; p = .03) during the drive phase of the jerk. Additionally, IMRRP-3 led to maintaining optimal lifting strategy by reducing the increase in horizontal displacement during the descending (3.85%; p = .04) and ascending (5.42%; p = .02) phases. Increasing IMRRP from 2min to 3min was also shown to enhance kinetic variables evidenced by prompting higher peak vGRF (2.01%; p = .04) and power (2.55%; p = .04). Conclusion: To better identify an athlete’s maximal jerk technique and power maintenance, the results of this study suggest 3min as more appropriate IMRRP during successive C&J at 100% 1RM.
Hypertension in obesity: novel insights.

Backround: The relationship between obesity and hypertension has been established in both adults and children. The combination of obesity, hypertension and other cardiovascular risk factors significantly increases the likelihood of adverse cardiovascular effects and raises concerns about aggressive treatment strategies. OBJECTIVE Despite the impressive elements which indicate an important role for excessive weight gain in increasing blood pressure, not all obese patients are hypertensive. A subgroup of obese people may not develop hypertension. Furthermore, masked hypertension occurs more common among obese patients, and body fat distribution has a major role in the development of hypertension. METHODS We conducted a research of the relevant literature regarding obesity-induced hypertension and possiple treatment strategies. RESULTS Successful weight loss is correlated with blood pressure reduction and requires a multidisciplinary approach that includes personalized dietary interventions combined with regular exercise and cognitive behavioral therapy. CONCLUSION Pharmacological therapy may be considered as part of a comprehensive obesity management strategy. More research and new treatment therapies are required at this field.
Effects of an Adenotonsillectomy on the Cognitive and Behavioural Function of Children Who Snore: A naturalistic observational study.

Objectives This study aimed to evaluate cognitive and behavioural changes among 9-14-year-old Omani children with obstructive sleep apnoea (OSA) after an adenotonsillectomy (AT). Methods This naturalistic observational study was conducted at the Sultan Qaboos University Hospital, Muscat, Oman, between January 2012 and December 2014. Omani children with adenotonsillar hypertrophy (ATH) underwent overnight polysomnography and those with confirmed OSA were scheduled for an AT. Cognitive and behavioural evaluations were performed using standardised instruments at baseline prior to the procedure and three months afterwards. Results A total of 37 children were included in the study, of which 24 (65%) were male and 13 (35%) were female. The mean age of the males was 11.4 ± 1.9 years, while that of the females was 11.1 ± 1.5 years. Following the AT, there was a significant reduction of 56% in mean apnoea-hypopnoea index (AHI) score (2.36 ± 4.88 versus 5.37 ± 7.17; P <0.01). There was also a significant positive reduction in OSA indices, including oxygen desaturation index (78%), number of desaturations (68%) and number of obstructive apnoea incidents (74%; P <0.01 each). Significant improvements were noted in neurocognitive function, including attention/concentration (42%), verbal fluency (92%), learning/recall (38%), executive function (52%) and general intellectual ability (33%; P <0.01 each). There was a significant decrease of 21% in both mean inattention and hyperactivity scores (P <0.01 each). Conclusion These results demonstrate the effectiveness of an AT in improving cognitive function and attention deficit hyperactivity disorder-like symptoms among children with ATH-caused OSA. Such changes can be observed as early as three months after the procedure.
