Published: April 2023

<p>Image registration is a technique of matching and superimposing of features, which can be better applied to high-level vision tasks. However, high-level vision tasks often pay more attention to analysis of target areas. In summary, we rethink the collaborative relationship between image registration and high-level vision tasks, and propose a local registration strategy for constructing a robust adaptive attention gauge fields, and construct robust adaptive attention gauge fields to register images focus more on important target areas. In order to improve the robustness and timeliness of the algorithm for feature matching of target areas in complex environments, we propose a robust adaptive probability distribution(RA), and construct robust adaptive mixed model expectation maximum attention(RAMM-EMA). In order to make robust adaptive parameters to reach the global optimum in deep learning, we designed a simulated annealing method to optimize the robust adaptive parameters during training. In order to focus on important regions in the image as much as possible, propose a feature fusion map with weak boundaries and probabilistic properties, called Robust Adaptive Attention Gauge Fields(RAA-Gauge Fields). High-level vision tasks experiments on image fusion, object delect and 3D-reconstruction, the method presented in this paper is the most helpful, and registration effect of the target areas perform best under more extreme conditions. </p>
Simulation Study of An Interleaved Flyback Converter for Micro Grid Systems Operating in the CCM Mode
Authors: Salihmuhsin Metin 
Published: April 2023

<p> This paper presents a design and an implementation of an isolated grid connected micro inverter system that is based on an interleaved flyback topology. The developed system gets input from a 250 W PV panel, converts the dc energy into ac and connects it to the grid. This work covers the simulation aspect of developing the above mentioned system where extensive simulations are performed in order to find and optimize values of desired parameters and simulate the overall system. The CCM (Continues Conduction Mode) of operation for the flyback converter is preferred as it generates considerably less amount of the current ripple at converter output when compared to DCM operation and less amount of power loss. A feedback loop with a PI controller is incorporated into the design in order to properly stabilize the system. Simulation results demonstrated that the developed system generates sinusoidal voltage and current signals of 50 Hz in frequency with desired amplitudes at the output of the system. Connection of generated ac waveforms to the grid is accomplished by means of a PLL block. THD of the grid current is found as 11.57% due to spikes at zero crossings. </p>
Analytical Model of 3D Helical Solenoids, for Efficient Computation of Dynamic EM Fields, Complex Inductance, and Radiation Resistance
Authors: Zadehgol Ata 
Published: April 2023

<p>We use the <em>dynamic </em>Green's function to produce a frequency-dependent magnetic vector potential $\vec{A}(\omega)$ and derive expressions for the efficient (accurate and fast) computation of cylindrical components of the magnetic flux density vector $\vec{B}(\omega)$ as a function of the solenoid's geometric and material parameters. $\vec{A}(\omega)$ may be used to efficiently compute the frequency-dependent flux linkage $\Phi(\omega)$, the complex inductance $L(\omega)$, and the radiation patterns of the solenoid anywhere in space including both near-field and far-field regions, excluding the (source) regions of conducting wire. Additionally, we propose the complex calibration coefficient $\chi(\omega)$ to account for the finite-radius conductor.</p>
<p>Several numerical examples are provided to validate the proposed helical model against the superposition of circular loops. The proposed model is demonstrated for a wide range of applications across the spectrum from 60 Hz to 170 GHz, representing low-frequency power systems to high-frequency mm-wave communication systems. A plan is being developed for experimental validation of the model. </p>

Authors: V Narayana Mannam , Jalihal Devendra , Nagendra S M Shiva , Giri Aswin 
Published: April 2023

<p>In vehicular mobility applications, sensor devices are exposed to rapidly varying concentrations of pollutants. Therefore, more than a conventional data set containing features such as sensor output, temperature and humidity is required to calibrate mobile sensors. We propose a new data set having additional features to address possible error sources encountered in vehicular-mobility LCS applications. We show that the proposed data set is a better choice for calibrating mobile LCS devices when compared to the conventional data set. Further, we propose and investigate two different tandem configurations involving a two-phase calibration approach to improve the calibration accuracy of mobile sensors. The calibration is done with real-time data obtained from an LCS device, SensurAir, which we developed and deployed in Chennai, India. </p>

Authors: Basir Anggi Anugerah , Yuliarni Syafrita  , Syarif Indra  
Published: April 2023

Background: Cystatin-C acts as a neuroprotector in the central nervous system at normal levels, but high serum cystatin-C levels are associated with impaired cognitive function. Serum cystatin-C levels increase in impaired renal function, and cognitive impairment are comorbidities that can increase the morbidity and mortality of chronic kidney disease patients. This study aimed to assess the relationship between serum cystatin-C levels and cognitive function in chronic kidney disease patients.
Methods: This study used a cross-sectional design with 73 samples of non-hemodialysis chronic kidney disease patients. Cognitive function was assessed using the MoCa-Ina. Serum cystatin-C levels of all samples were measured by the ELISA method. Data analysis was carried out using SPSS.
Results: Impaired cognitive function in CKD patients was found to be 76.7%. The median serum cystatin-C level of CKD patients with impaired cognitive function (n=56) was 1.015 mg/dL, and without cognitive impairment (n=17) was 0.929 mg/dL. There was no significant relationship between serum cystatin-C levels (cut-off point 0.98 mg/dL) and impaired cognitive function (OR : 2.05, 95% CI : 0.680-6.175, p= 0.198).
Conclusion: There is no relationship between serum cystatin-C levels and cognitive function impairment in non-hemodialysis chronic kidney disease patients.

The availability of non-instrumental information increases risky decision-making
Authors: Matthews Julian R. , Cooper Patrick S. , Bode Stefan , Chong Trevor T.-J. 
Published: April 2023

AbstractContemporary models of decision-making under risk focus on estimating the final value of each alternative course of action. According to such frameworks, information that has no capacity to alter a future payoff (i.e., is “non-instrumental”) should have little effect on one’s preference for risk. Importantly, however, recent work has shown that information, despite being non-instrumental, may nevertheless exert a striking influence on behavior. Here, we tested whether the opportunity to passively observe the sequence of events following a decision could modulate risky behavior, even if that information could not possibly influence the final result. Across three experiments, 71 individuals chose to accept or reject gambles on a five-window slot machine. If a gamble was accepted, each window was sequentially revealed prior to the outcome being declared. Critically, we informed participants about which windows would subsequently provide veridical information about the gamble outcome, should that gamble be accepted. Our analyses revealed three key findings. First, the opportunity to observe the consequences of one’s choice significantly increased the likelihood of gambling, despite that information being entirely non-instrumental. Second, this effect generalized across different stakes. Finally, choices were driven predominantly by the likelihood that information could result in an earlier resolution of uncertainty. These findings demonstrate the importance of anticipatory information to decision-making under risk. More broadly, we provide strong evidence for the utility of non-instrumental information, by demonstrating its capacity to modulate primary economic decisions that should be driven by more motivationally salient variables associated with risk and reward.

Authors: Menikarachchi Lochana , Jayantha Malith 
Published: April 2023

Background: User-generated online drug reviews can give insights into patients’ perspectives on drug therapy and adverse reactions. This information can also be used to augment traditional pharmacovigilance systems that suffer from underreporting. The goal of this study was to analyze adverse effects, patients’ perspectives and offlabel uses of metoclopramide through text mining. Methods: User reported drug reviews on metoclopramide were obtained from two online health forums (Drugs.com and WebMD.com) through web scraping. The raw data were preprocessed and analyzed with text mining techniques such as bag-of-words analysis and sentimental analysis. Visual data analysis techniques such as word clouds and bar plots were used to draw important conclusions from the data. Results: Migraine and nausea were the most reported indications in Drugs.com and WebMD.com datasets, respectively. Text analytics show both FDA approved and off-label uses of metoclopramide. Anxiety and spasm were the most frequently reported adverse reactions in Drugs.com and WebMD.com datasets, respectively. Sentimental analysis showed that about 66% of the reviews on Drugs.com were negative, while 34% were positive. The analysis of the WebMD.com dataset revealed a similar finding with 64% negative reviews and 36% positive reviews. Conclusions: User reported adverse reactions on both health forums were consistent with known adverse reactions of metoclopramide. They included both mild (drowsiness, sleepiness, dizziness, fatigue, tiredness, bloating, diarrhea) and severe adverse reactions such as movement disorders (spasm, dyskinesia, Parkinson like symptoms) and psychiatric disorders (anxiety, confusion, panic, restlessness, depression). Patients’ perspectives toward metoclopramide therapy were generally negative. Text analytics also revealed several off-label uses (migraine and hyperemesis) of metoclopramide.

Authors: Liyanage Liyanage R. S. , Wickramarathne Hiran T. , Kalpana Pahala Ranaweerage U. , Hewavithana Padma B. 
Published: April 2023

Background: Modern fluoroscopic C-arms have substantially expanded the use of fluoroscopic C-arms in a variety of orthopaedic surgical procedures. Fluoroscopy professionals who are exposed to radiation for an extended period of time have an increased risk of developing radiation-induced cancer. The study aimed to evaluate the radiation protection precautions taken by theater staff in two selected hospitals to reduce occupational radiation doses during fluoroscopy-guided common orthopaedic surgeries. Methods: After examining the theatre records for three months in two selected hospitals in Sri Lanka, the three major orthopaedic surgeries for both hospitals were selected (Dynamic Hip Screw, Tibial Plateau Fracture, and Distal Radial Fracture). The study used a checklist for an unbiased observation, containing the internationally recommended guidelines for Fluoroscopy inside an interventional suit published in the International Commission on Radiological Protection (ICRP) 139 publication to check whether the theatre personnel followed the radiation protective measures during their procedures. Results: Fluoroscopy technical-based protective measures and the quality assurance-related criteria were satisfied to a 100% level. Both hospitals, A and B, did not have an adequate number of lead shielding devices to be utilized in theatres. A lack of individual exposure monitoring and the use of two dosimeters were identified as the main problems. Conclusions: The staff of both hospitals adhered to the standard international guidelines on radiation protection during C-arm guided orthopaedic surgeries despite the unavailability of a proper personal monitoring system.

Background: In this digital age, the use of screens has become an essential part of life. The COVID-19 pandemic has intensified the use of screens, especially among students. This study aimed to find the association between screen time and the level of perceived stress among students of University of Peradeniya during COVID-19 pandemic. Methods: In this cross-sectional study, a pretested questionnaire consisting of the 18-item screen time questionnaire and perceived stress scale (PSS) questionnaire was distributed among all the undergraduate students of the University of Peradeniya at the time of the study, via email, and a representative sample (N = 387, mean age = 22.964 ± 1.818 years) was selected from the responses received. Results: Mean screen time was found to be 13h 27 min± 4h 52 min, and the most used screen type among males was laptop/computer, and among females, smartphone. The mean perceived stress of the sample was 20.499 ± 5.393. Spearman correlation for screen time and perceived stress showed a significant weak positive correlation (Spearman rho = 0.132, p = 0.009) between screen time and perceived stress. Neither screen time nor perceived stress was associated with gender [F (1, 385) = 1.05, p = 0.307]. Conclusions: Most students have moderate perceived stress, and the study shows a significant weak positive correlation between screen time and perceived stress during the COVID-19 pandemic. It was observed that perceived stress is not significantly deviate from pre-pandemic values. Longitudinal studies for assessing perceived stress are necessary to find a cause-effect relationship.

Authors: Chauhan V. S. , Chatterjee Kaushik , Yadav Arun Kumar , Srivastava Kalpana , Prakash Jyoti , Yadav Prateek , Dangi Ankit 
Published: April 2023

Background:
Health-care workers (HCWs) in COVID-19 pandemic have faced the major impact in providing care to infected persons. Most of the studies on mental health impact among HCW have not incorporated paramedical staff. Furthermore, they have not compared psychological morbidity among HCW on the basis of high COVID exposure (HCE) and low COVID exposure (LCE). To address the above gap, this study aimed at evaluating mental health impact among HCW and its associated risk factors.

Materials and Methods:
Consecutive 200 HCWs each in the HCE and LCE groups (between the age group of 18 and 60 years) were enrolled from two tertiary care hospitals providing COVID-19 treatment from August 1, 2020. After collection of sociodemographic data, participants were administered Impact of Event Scale-Revised, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7 Scale.

Results:
The difference in stress, depression, and anxiety symptom scores between the HCE and LCE groups was not statistically significant. Multiple regression analysis revealed that female sex was associated with higher scores in all the three domains. The effect remained significant even after adjusting for effect of other risk factors.

Conclusion:
HCE or LCE was associated with similar impact in terms of stress, depression, and anxiety among HCWs. Female HCWs had a higher prevalence of stress, depression, and anxiety. Doctors, nurses, and paramedics had a similar prevalence of stress, depression, and anxiety when odds were adjusted.
