A review on techniques and modelling methodologies used for checking electromagnetic interference in integrated circuits

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Theoretical and experimental investigation of thiourea derivatives: synthesis, crystal structure, in-silico and in-vitro biological evaluation

ABSTRACT. In this study, five different thiourea derivatives were synthesized from aryl amines according to the reported method. 1-Benzoyl-3-(4-methoxyphenyl)thiourea (2) was confirmed with single crystal XRD analysis while 1-benzoyl-3-phenylthiourea (1), 1-benzoyl-3-(4-hydroxyphenyl)thiourea (3), 1-benzoyl-3-(2-nitrophenyl) thiourea (4) and 1-benzoyl-3-p-tolylthiourea (5) were elucidated with FTIR and NMR techniques. The geometry optimization of the targeted molecules was accomplished with density functional theory applying B3LYP function. The experimental (XRD) and calculated (DFT) bond angles and bond lengths were compared. The frontier molecular orbitals and molecular electrostatic potential were computed to determine the charge density distribution and possible sites for electrophilic and nucleophilic reactions of the crystalline compound. The synthesized compounds were evaluated as an anti-radical scavenger and enzyme (esterases and protease) inhibitor using in-vitro models. The results confirmed that the synthesized molecules have good anti-oxidant property while a moderate enzyme inhibiting activity. Docking study was conducted with acetylcholine and butyrylcholine esterase which suggested that molecules under study have a potential to inhibit these esterases and protease enzymes. On the basis of in-vitro studies, it is concluded that compound 2 is most active against all tested assays.

THE CELLULAR PARTICLE SWARM OPTIMIZATION ALGORITHM

This work presents a variant of the Particle Swarm Optimization (PSO) original algorithm, the Cellular-PSO. Inspired by the cellular Genetic Algorithm (GA), particles in Cellular-PSO are arranged into a matrix of cells interconnected according to a given topology. Such topology defines particle’s neighborhood, inside which social adaptation may occur. As a consequence, population diversity is increased and the optimization process becomes more efficient and robust. The proposed Cellular-PSO has been applied to the nuclear reactor core design optimization problem and comparative experiments demonstrated that it is superior to the standard PSO.
Research on the Influence of Invisible Knowledge Learning in Online Learning on Students' Entrepreneurial Orientation

Knowledge management is the inevitable product of the information age, and knowledge transformation is the result of the interaction between network learners and learning resources. The four aspects of the SECI (Socialization, Externalization, Combination, Internalization) model can help students accelerate their learning of entrepreneurial tacit knowledge in e-learning to realize the construction of entrepreneurial knowledge with entrepreneurial orientation as the core. Based on the SECI model, this paper proposes four hypotheses on the effects of tacit knowledge learning on students’ entrepreneurial orientation in e-learning. It takes e-learning familiarity as the regulating variable and analyzes the regulating effect of tacit knowledge learning on students’ entrepreneurial orientation and whether their grade, discipline, and gender will lead to significant differences in entrepreneurial orientation. The results indicate that the questionnaire designed in this paper has generally effective α. The coefficient is 0.865 and the reliability level is good. The minimum value of the AVE (Average variance extraction) was 0.545 and the minimum value of CR (Combinatorial reliability) was 0.819, indicating that the overall validity and structural validity were high. The three aspects of sociality, dominance, and recessiveness cause the learning of tacit knowledge to have an obvious positive effect on students’ entrepreneurship. The results of this study have important reference value for promoting teachers’ entrepreneurial knowledge sharing and innovation and cultivating students’ entrepreneurial orientation.
The Frequency of Contacting Persons you Dreamed About: A Social Aspect of Dreaming

Although dreams are very private, dreaming has also social components, i.e., dreams are shared quite often. We studied the frequency of how often the dreamer deliberately contacted another person because s/he dreamed about this person, as this might intensify the waking-life bonds with this person. Overall, 2929 participants completed the dream survey, and a subsample also completed a Big Five Personality inventory. The findings indicate that 37% of the participants contacted other persons because they dreamed about them. Dream recall frequency, attitude towards dreaming, younger age, and female gender was associated with contacting the person(s) dreamed of. Moreover, extraversion was also related to the frequency of contacting the person(s) dreamed of – similar to the relationship found for dream sharing frequency and extraversion. However, the association with low conscientiousness is a new finding. It would be very interesting to test whether this social behavior (contacting another person) motivated by dreams strengthens the social bonds between the dreamer and the contacted person(s) and thereby provide support for the Social Simulation Theory.
Index establishment and capability evaluation of space–air–ground remote sensing cooperation in geohazard emergency response

Abstract. Geohazard emergency response is a disaster event management act that is multifactorial, time critical, task intensive and socially significant. To improve the rationalization and standardization of space–air–ground remote sensing collaborative observations in geohazard emergency responses, this paper comprehensively analyzes the technical resources of remote sensors and emergency service systems and establishes a database of technical and service evaluation indexes using MySQL (Structured Query Language). Based on the database, we propose the method of using the technique for order preference by similarity to an ideal solution (TOPSIS) and a Bayesian network to evaluate the synergistic observation effectiveness and service capability of remote sensing technology in geohazard emergency response, respectively. We demonstrate through experiments that using this evaluation can effectively grasp the operation and task completion of remote sensing cooperative technology in geohazard emergency response. This provides a decision basis for the synergistic planning work of heterogeneous sensors in geohazard emergency response.

Liver-Directed Treatment Options Following Liver Tumor Recurrence: A Review of the Literature

Recurrence following curative-intent hepatectomy for colorectal cancer liver metastasis, hepatocellular carcinoma, or cholangiocarcinoma is unfortunately common with a reported incidence as high as 75%. Various treatment modalities can improve survival following disease recurrence. A review of the literature was performed using PubMed. In addition to systemic therapy, liver-directed treatment options for recurrent liver disease include repeat hepatectomy, salvage liver transplantation, radiofrequency or microwave ablation, intra-arterial therapy, and stereotactic body radiation therapy. Repeat resection can be consider for patients with limited recurrent disease that meets resection criteria, as this therapeutic approach can provide a survival benefit and is potentially curative in a subset of patients. Salvage liver transplantation for recurrent hepatocellular carcinoma is another option, which has been associated with a 5-year survival of 50%. Salvage transplantation may be an option in particular for patients who are not candidates for resection due to underlying liver dysfunction but meet criteria for transplantation. Ablation is another modality to treat patients who recur with smaller tumors and are not surgical candidates due to comorbidity, liver dysfunction, or tumor location. For patients with inoperable disease, transarterial chemoembolization, or radioembolization with Yttrium-90 are liver-directed intra-arterial therapy modalities with relatively low risks that can be utilized. Stereotactic body radiation therapy is another palliative treatment option that can provide a response and local tumor control for smaller tumors.

Materials were exchanged between the consultant researcher and teachers through the mail or a delivery service. Videoconferences allowed for interactions between teachers of different regions and teaching situations. In spite of the limitations, the results revealed progress. The data reveal difficulties, beliefs and theories, which are reflected in the classroom. Implications and suggestions form this distance learning
The chloroplast genome of Sonneratia ovata: genome structure and comparative analysis

Abstract Sonneratia ovata is one of the most widely distributed mangrove species worldwide. In this study, the complete chloroplast (cp) genome of S. ovata was sequenced and assembled; its phylogenetic position was confirmed in Lythraceae. The total size of cp genome was 153,052 bp, exhibiting a typical quadripartite structure with a large single copy (LSC) region of 87,238 bp and a small single copy (SSC) region of 18,002 bp, two inverted repeats (IRs) regions of 23,906 bp each. The overall GC content was 37.3%, respectively. We detected 128 genes in cp genome, including 84 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. A phylogenetic analysis showed that S. ovata has a close relationship with S. apetala within the genus Sonneratia.
Association between traumatic brain injury (TBI) patterns and mortality: a retrospective case-control study

Background: Low and medium income countries (LMICs) such as Kenya experience nearly three times more cases of traumatic brain injury (TBI) compared to high income countries (HICs). This is primarily exacerbated by weak health systems especially at the pre-hospital care level. Generating local empirical evidence on TBI patterns and its influence on patient mortality outcomes is fundamental in informing the design of trauma-specific emergency medical service (EMS) interventions at the pre-hospital care level. This study determines the influence of TBI patterns and mortality. Methods: This was a case-control study with a sample of 316 TBI patients. Data was abstracted from medical records for the period of January 2017 to March 2019 in three tertiary trauma care facilities in Kenya. Logistic regression was used to assess influence of trauma patterns on TBI mortality, controlling for patient characteristics and other potential confounders. Results: The majority of patients were aged below 40 years (73%) and were male (85%). Road traffic injuries (RTIs) comprised 58% of all forms of trauma. Blunt trauma comprised 71% of the injuries. Trauma mechanism was the only trauma pattern significantly associated with TBI mortality. The risk of dying for patients sustaining RTIs was 2.83 times more likely compared to non-RTI patients [odds ratio (OR) 2.83, 95% confidence interval (CI) 1.62-4.93, p=0.001]. The type of transfer to hospital was also significantly associated with mortality outcome, with a public hospital having a two times higher risk of death compared to a private hospital [OR 2.18 95%CI 1.21-3.94, p<0.009]. Conclusion: Trauma mechanism (RTI vs non-RTI) and type of tertiary facility patients are transferred to (public vs private) are key factors influencing TBI mortality burden. Strengthening local EMS trauma response systems targeting RTIs augmented by adequately resourced and equipped public facilities to provide quality lifesaving interventions can reduce the burden of TBIs.
Hepatic dual-contrast CT imaging: slow triple kVp switching CT with CNN-based sinogram completion and material decomposition

Abstract. Purpose: Dual-contrast protocols are a promising clinical multienergy computed tomography (CT) application for focal liver lesion detection and characterization. One avenue to enable multienergy CT is the introduction of photon-counting detectors (PCD). Although clinical translation is highly desired because of the diagnostic benefits of PCDs, it will still be a decade or more before they are broadly available. In our work, we investigated an alternative solution that can be implemented on widely used conventional CT systems (single source and integrating detector) to perform multimaterial spectral decomposition for dual-contrast imaging. Approach: We propose to slowly alternate the x-ray tube voltage between 3 kVp levels so each kVp level covers a few degrees of gantry rotation. This leads to the challenge of sparsely sampled projection data in each energy level. Performing the material decomposition (MD) in the sinogram domain is not directly possible as the projection images of the three energy levels are not angularly aligned. In order to overcome this challenge, we developed a convolutional neural network (CNN) framework for sparse sinogram completion (SC) and MD. To evaluate the feasibility of the slow kVp switching scheme, simulation studies of an abdominal phantom, which included liver lesions, were conducted. Results: The line-integral SC network yielded sinograms with a pixel-wise RMSE < 0.05 of the line-integrals compared to the ground truth. This provided acceptable image quality up to a switching angle of 9 deg per kVp. The MD network we developed allowed us to differentiate iodine and gadolinium in the sinogram domain. The average relative quantification errors for iodine and gadolinium were below 10%. Conclusions: We developed a slow triple kVp switching data acquisition scheme and a CNN-based data processing pipeline. Results from a digital phantom validation illustrate the potential for future applications of dual-contrast agent protocols on practically available single-energy CT systems.
Preparation, spectral study and antimicrobial activity of binary Co(II) complexes derived from 2’-hydroxy chalcones

ABSTRACT. The present work comprises preparation, characterization, thermal behavior and growth inhibitory activity of some novel Co(II) complexes derived from substituted (E)-1-(1-hydroxy-4-iodonaphthalen-2-yl)-3-phenylprop-2-en-1-one (L1) and (E)-1-(4-bromo-1-hydroxynaphthalen-2-yl)-3-phenylprop-2-en-1-one (L2-L6). Newly synthesized metal-ligand complexes were structurally confirmed with suitable spectroscopic technique such as FT-IR, EPR, NMR (both 1H and 13C). XRD analysis for complex C1 confirmed the crystal system; tetragonal and space group; P 42/n: 2 with unit cell dimensions a, b = 13.3516 Å, c = 10.8009 Å; α, β, γ = 90o. The IR and EPR study demonstrated that interaction between metal ions and ligand occurs through carbonyl oxygen and hydroxyl oxygen. From the values of magnetic moment (μ) it was observed that synthesized complexes (C1-C6) are paramagnetic with three unpaired electrons contain one electron in t2g orbital and two electrons in eg orbitals. Further all these complexes have been evaluated in-vitro for their antimicrobial activity against the Gram positive bacteria Staphylococcus aureus, Gram negative bacteria Escherichia coli and the yeast Candida albicans. The complex C1 showed the significant antimicrobial activity, whereas the complexes C2, C4, C5 and C6 are moderately active against the tested pathogens. The antimicrobial data revealed that growth inhibitory activities of complexes were enhanced comparatively than its respective ligands. The enhanced antimicrobial activity is attributed to the presence of halogens (Br, Cl, I) and hydroxyl (OH) active substituents associated with the basic nucleus of complexes. Therefore, the present study helps to develop a new class of antimicrobial analogues.

Effect of electrodes material on the I-V-curve and switching of memristors on the base of electroformed open metal-SiO2-metal sandwich structure

The study of electroforming processes in various open sandwich metal-SiO2-metal structures (with different materials of electrodes) and I–V-curves at both voltage polarities allowed to find the main factor responsible for the presence of stable electroforming and the absence of breakdowns after electroforming (N-shape I-V-curve can be drawn repeatedly). This factor is making of structure anode of tungsten at any (top or bottom) position of this electrode. The use of molybdenum instead of tungsten in such structures essentially allows to decrease the electroforming voltage (from 10-11 to 4-5 V), which makes the process more reliable.
A perspective on development of fuel cell materials: Electrodes and electrolyte

The declining reserves and environmental concerns related to the use of fossil fuels have made the global think tanks to pursue for the technologies considered to be renewable as well as sustainable. Fuel cell technology is emerging and a green way to produce electricity, provided sufficient amount of hydrogen (fuel) is available that directly convert chemical energy to electrical energy. Despite of being an efficient and eco‐friendly source of energy, commercialization of fuel cells is still difficult to attain. Techno‐economic challenges like high manufacturing and assembly costs, water management, system size, nondurability, and instability of the system need to be addressed. In order to resolve these issues, considerable research has been carried out for the development of novel and inexpensive materials for the fuel cells. In this article, we have reviewed the development of electrodes and electrolyte materials for different types of fuel cells. A detailed description of applications, challenges, and improvement of electrodes/electrolytes materials of different types of fuel cells (polymer electrolyte membrane fuel cells, direct methanol fuel cells and solid oxide fuel cells) have been reported in this review article. A brief review of the development of materials for electrode of molten carbonate fuel cells has also been presented in the review.
