Effects of different mixing methods on the conductivities of poly(2-ethyl aniline)/graphene and poly(2-ethyl aniline)/expanded graphite composites

Abstract In this study, the preparation of poly(2-ethyl aniline) (PEAn)/Graphene and PEAn/Expanded Graphite (EG) composites using different mixing methods and the effect of the preparation conditions of composites on their electrical conductivities were investigated. Herein, it was examined both the effect of the sonication time of EG and Graphene in HCl medium before the polymerization on their homogeneous dispersion in the PEAn matrix and the effect of the three different mixing methods, including magnetic stirring, ultrasonication, and ball milling, on the formation of network in the composites. From the morphological characterization obtained by SEM, due to π-π* electron interaction, 2-EAn molecules were polymerized on the surface of graphene and EG. It was determined that the composite with the highest conductivity was obtained by in situ polymerization of 2-EAn in the presence of graphene via a ball milling method for 10 h, after the sonication of graphene in aqueous HCl medium for 6 h. The conductivity of this PEAn/Graphene (1:1 by weight) composite increased from 3.5x10−7 Scm−1 to 1.57 Scm−1 compared to pure PEAn.
Clinical Utility of Medication-Based Risk Scores to Reduce Polypharmacy and Potentially Avoidable Healthcare Utilization

The management of multiple chronic health conditions often requires patients to be exposed to polypharmacy to improve their health and enhance their quality of life. However, exposure to polypharmacy has been associated with an increased risk for adverse effects, drug-drug interactions, inappropriate prescribing, medication nonadherence, increased healthcare utilization such as emergency department visits and hospitalizations, and costs. Medication-based risk scores have been utilized to identify patients who may benefit from deprescribing interventions and reduce rates of inappropriate prescribing. These risk scores may also be utilized to prompt targeted discussions between patients and providers regarding medications or medication classes contributing to an individual’s risk for harm, eventually leading to the deprescribing of the offending medication(s). This opinion will describe existing medication-based risk scores in the literature, their utility in identifying patients at risk for specific adverse events, and how they may be incorporated in healthcare settings to reduce rates of potentially inappropriate polypharmacy and avoidable healthcare utilization and costs.
Impact of Inhaled and Intranasal Corticosteroids Exposure on the Risk of Ocular Hypertension and Glaucoma: A Systematic Review and Meta-Analysis

Purpose Starting in 2019, the Global Initiative for Asthma recommended the use of inhaled corticosteroids (ICS) as part of reliever combination therapy in patients 12 years of age and older, thus dramatically increasing the population exposure to ICS. ICS and intranasal corticosteroids (INS) are commonly used for a variety of respiratory diseases. Chronic steroid use is a well-known risk factor for elevated intraocular pressure (IOP) and glaucoma regardless of route of administration. This study aimed to determine the reported risk of glaucoma, ocular hypertension (OHT) and IOP elevation associated with ICS and INS use. Materials and Methods Systematic literature search in MEDLINE, EMBASE, Cochrane, CINAHL, BIOSIS, and Web of Science databases from the date of inception identified studies that assess ocular outcomes related to glaucoma in ICS and INS users. Study selection, risk of bias assessment and data extraction were done independently in duplicate. Meta-analysis assessed glaucoma incidence, OHT incidence and IOP changes in patients using ICS and INS. Study adhered to PRISMA guidelines. Study protocol was registered with PROSPERO: CRD42020190241. Results Qualitative and quantitative analyses included 65 and 41 studies, respectively. Incidence of glaucoma was not significantly different in either ICS or INS users compared to control over 45,457 person-years of follow-up. Similarly, no significant difference in OHT incidence over 4431 person-years was detected. In studies reporting IOP, a significantly higher IOP was observed (0.69 mmHg) in 857 ICS or INS users compared to 615 controls. However, no significant increase in IOP was observed within ICS or INS users when compared to pre-treatment baseline. Conclusion Overall, use of ICS or INS does not significantly increase the incidence of glaucoma or OHT. However, ICS and INS patients had significantly higher IOPs compared to untreated patients. Awareness of these findings is significant in care of patients with additional risk factors for glaucoma.
Diagnostic Management of Acute Pulmonary Embolism in COVID-19 and Other Special Patient Populations

Venous thromboembolism (VTE), in particular acute pulmonary embolism (PE), has been shown to be a frequent and potentially fatal complication of coronavirus disease 2019 (COVID-19). In response to the observed thrombotic complications, a large number of studies has been devoted to the understanding and management of COVID-19-associated coagulopathy. Notably, only a limited number of mostly retrospective studies has focused on the optimal diagnostic strategy for suspected PE in COVID-19 patients. As in other special populations, the accuracy of diagnostic algorithms for PE-exclusion has been debated in this specific patient subgroup as the specificity of D-dimer assays and clinical decision rules (CDRs) may be lower than normal. From this viewpoint, we discuss the current state-of-the-art diagnostic algorithms for acute PE with a focus on patients with COVID-19 in the perspective of other special patient populations. Furthermore, we summarize current knowledge regarding the natural history of PE resolution with anticoagulant treatment in patients with COVID-19.
Effects of Organizational Culture on Employer Attractiveness of Hotel Firms: Topic Modeling Approach

As the acquisition and retention of motivated and skilled employees are key to the high performance of hotel firms, employer attractiveness of hotel firms is a critical factor in achieving competitive advantage. Focusing on organizational culture, this study analyzes how different cultural attributes affect hotel firms’ attractiveness as employers. For the empirical analysis, this study collected 54,040 reviews of 157 large hotel chains and firms from Glassdoor in the United States. This study combines an unsupervised machine learning tool for topic modeling (latent Dirichlet allocation) with the coding process of researchers to measure the different cultural attributes of hotel firms. The research results show the positive and significant impact of four cultural attributes—collaborative, employee development, fair compensation, and customer focus—on employer attractiveness measured by both users’ employer satisfaction and recommendations to friends. In contrast, an innovation culture has no significant effect on attractiveness.
Artificial Intelligence Applications in K-12 Education: A Systematic Literature Review

Education is a vital part of the development of society and it is changing over time in terms of methods, content, concepts, and models. Recently, it has been increasingly prevalent to benefit from the potentialities of Artificial Intelligence (AI) in addressing educational issues. In this research, the current state of the art of the integration of AI in K-12 education was provided. Specifically, different parts of education in which AI was employed along with the related AI categories were discussed according to different K-12 grades and courses. Additionally, technologies and environments that contributed to employing AI in education were discussed. To this end, a systematic literature review was conducted on articles and conference papers published between 2011 and 2021 in the Web of Science and Scopus databases. As the result of the initial search, 2075 documents were extracted and based on inclusive criteria and 210 documents were identified for further investigation. AI applications were categorized into Student performance, Teaching, Selection, and Behavior tasks, and Other. Machine Learning (ML) and Intelligent Tutoring System (ITS) were the most common approaches among AI categories. Furthermore, high school-related applications were more frequent and STEM courses were substantially targeted by AI. In conclusion, the remarkable impact of AI on education was concluded. The current study reveals information about the potentialities offered by AI in K-12 education which aids researchers in implementing AI-based education systems. As for future works, other databases such as ACM library and Google Scholar can be investigated as well. Furthermore, exploring the 95 papers that were excluded due to inaccessibility to their full texts can be taken into account. Finally, the papers can be also investigated in terms of pedagogical approaches or development tools.
3D Printable Composite Polymer Electrolytes: Influence of SiO2 Nanoparticles on 3D-Printability

We here demonstrate the preparation of composite polymer electrolytes (CPEs) for Li-ion batteries, applicable for 3D printing process via fused deposition modeling. The prepared composites consist of modified poly(ethylene glycol) (PEG), lithium bis(trifluoromethylsulfonyl)imide (LiTFSI) and SiO2-based nanofillers. PEG was successfully end group modified yielding telechelic PEG containing either ureidopyrimidone (UPy) or barbiturate moieties, capable to form supramolecular networks via hydrogen bonds, thus introducing self-healing to the electrolyte system. Silica nanoparticles (NPs) were used as a filler for further adjustment of mechanical properties of the electrolyte to enable 3D-printability. The surface functionalization of the NPs with either ionic liquid (IL) or hydrophobic alkyl chains is expected to lead to an improved dispersion of the NPs within the polymer matrix. Composites with different content of NPs (5%, 10%, 15%) and LiTFSI salt (EO/Li+ = 5, 10, 20) were analyzed via rheology for a better understanding of 3D printability, and via Broadband Dielectric Spectroscopy (BDS) for checking their ionic conductivity. The composite electrolyte PEG 1500 UPy2/LiTFSI (EO:Li 5:1) mixed with 15% NP-IL was successfully 3D printed, revealing its suitability for application as printable composite electrolytes.
Facile synthesis of biodegradable corn starch-based plastic composite film reinforced with zinc oxide nanoparticles for packaging applications

Abstract The present study deals with the novel biogenic synthesis of cornflour-based biodegradable film in the presence of zinc oxide nanoparticles (ZnO NPs) as nanofiller through solution casting method. However, the ZnO NPs were prepared through precipitation method. The absorbance peak at 350 nm confirmed the formation of stable, monodispersed ZnO NPs. High resolution-scanning electron microscopy analysis showed crystalline nature of ZnO NPs with spherical morphology. Fourier transform infrared analysis revealed changes in functional groups as a result of hydrogen bond interaction between matrix, plasticizer, and ZnO NPs. Moisture content and percentage solubility test showed that increase in ZnO NPs content decreased moisture content and percentage solubility of hybrid nanocomposite. In addition, the hybrid film with maximum ZnO content showed least water uptake. The biodegradability of 7 wt% ZnO hybrid composites displayed initial rise in mineralization rate that eventually decrease with time.
Selected parameters characterizing physical activity behavior in pupils of the second grade of elementary school in the Ústí Region, Czech Republic

Background: By the application of pedometers and subjective evaluation techniques, one can obtain information about the importance of physical activities (PA) in the lifestyles of adolescents. The conduct of PA in the Ústí Region, which is a structurally affected region within the Czech Republic, may be specifically impinged upon. Objective: The aim of this study is to establish indicators of adolescent participation in PA during school days and weekends and to evaluate them from the point of view of recommended criteria for health. We compare our findings with other studies and draw attention to the role of school movement programs. Methods: Physical activity was concurrently and objectively monitored by the Yamax SW-700 and SW-800 pedometer for a period of seven consecutive days. An identification and recording sheet were used for the registration of results. A total of 285 boys and 276 girls from elementary schools in the Ústí Region participated in the survey. Pedometers were applied during normal school attendance. Kruskal-Wallis and Mann-Whitney tests were used to assess differences between days of the week in boys and girls. A daily step count (SC) was compared with the recommended criteria for health. The daily recommendation amounted to ≥ 13,000/11,000 SC for 12-year-old children and ≥ 10,000 SC for 13–15-year-old adolescents. Results: The daily SC values for boys were 10,702 ± 4,474, and for girls the lower 9,841 ± 3,722 ( p = .02, r = .10). Weekend days were accompanied by a decrease in values in boys compared to school days ( p ˂ .001, r = .20) and girls ( p ˂ .001, r = .17). 43.2% of boys and 35.9% of girls meet the recommended health criteria. PA participation time is higher in boys than in girls during school days ( p ˂ .001, r = .25) compared to ( p ˂ .001, r = .22). The importance of school movement programs becomes evident. Conclusions: Boys achieve higher daily values than girls in all monitored indicators. The lowest SC levels are those reached by the oldest group of adolescents during weekends.
A systematic evaluation of accelerating indoor airflow simulations using cross-platform parallel computing

With new advances in computer hardware and software, users now have widespread accessibility to multicore devices inside personal computers making it feasible for fast indoor airflow simulations. Some exciting preliminary results of a cross-platform parallel computing framework OpenCL using specific hardware were reported. However, those results are largely based on two hypotheses: 1. OpenCL code on all devices will generate the same results; 2. On the same device, running in parallel with multiple processors will be faster than running in sequential with a single processor. This study attempted to evaluate these two hypotheses by systematically studying the accuracy and computing speed of OpenCL for indoor airflow simulations. A Fast Fluid Dynamics (FFD) code was selected as an exemplar indoor airflow simulation program. To compare the cross-platform ability of OpenCL, the evaluation was performed using four Graphics Processing Units (GPUs) and five Central Processing Units (CPUs) from three manufacturers, with different degrees of computing capability and mounted on two operating systems. The test subjects were evaluated using four case studies consisting of various indoor airflows. A sequential FFD code programmed in C and a Computational Fluid Dynamics (CFD) program were first used to perform the case studies and generate numerical benchmarks. The comparison of the numerical simulation results with experimental data showed that CFD and FFD can predict the studied flows with averaged relative errors of 9.99% and 11.30%, respectively. Afterwards, the accuracy and speedup of the OpenCL code was compared with numerical benchmarks. Although the OpenCL code on the CPUs generated identical numerical results, the OpenCL results from the GPUs were slightly dissimilar. This is likely due to varying interpretations, by the manufactures, of an Institute of Electrical and Electronics Engineers standard. Depending on the hardware, the speedups of the OpenCL code varied from 0.7 to 4.2 times on the CPUs and 5.1–129.3 times on the GPUs. The slowdown of computing speed happened when running OpenCL on a two-core CPU in a Windows Operating System using the Boot Camp on a Mac computer. Finally, a separate study on the relationship between speedup and global work size showed that a speedup of 1139 can be achieved when using an AMD FirePro W8100 GPU.
On‐frame gap‐coupled half‐loop antenna with a narrow ground clearance for the LTE smartphone

An on‐frame gap‐coupled half‐loop antenna with a 3‐mm narrow ground clearance disposed at the short edge (bottom or top edge) of the modern LTE smartphone is presented. The antenna has two gap‐coupled half‐loops (first and second half‐loops) formed between an on‐frame metal strip and the device ground plane in the smartphone. The on‐frame metal strip comprises a first strip and a second strip and is disposed on the inner surface of the short‐edge frame of the smartphone casing. No extension of the on‐frame metal strip to two long side edges of the smartphone casing is needed. Two ends of the on‐frame metal strip are connected to the device ground plane through two inductors. Both the first and second strips are also gap‐coupled to a step‐shape feed strip disposed on the narrow ground clearance between the on‐frame metal strip and the device ground plane, thereby forming the first and second half‐loops. The two half‐loops are excited to contribute their fundamental and higher‐order resonant modes to form two operating bands to respectively cover the 824–960 and 1710–2690 MHz for the LTE operation. The antenna structure and operating principle are addressed in this study. Experimental results of the fabricated antenna are presented to verify the simulation study. Effects of the user's hand on the performance of the antenna are also analyzed. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2344–2351, 2016
Anomalous Metallic Phase in Molybdenum Disulphide Induced via Gate-Driven Organic Ion Intercalation

Transition metal dichalcogenides exhibit rich phase diagrams dominated by the interplay of superconductivity and charge density waves, which often result in anomalies in the electric transport properties. Here, we employ the ionic gating technique to realize a tunable, non-volatile organic ion intercalation in bulk single crystals of molybdenum disulphide (MoS2). We demonstrate that this gate-driven organic ion intercalation induces a strong electron doping in the system without changing the pristine 2H crystal symmetry and triggers the emergence of a re-entrant insulator-to-metal transition. We show that the gate-induced metallic state exhibits clear anomalies in the temperature dependence of the resistivity with a natural explanation as signatures of the development of a charge-density wave phase which was previously observed in alkali-intercalated MoS2. The relatively large temperature at which the anomalies are observed (∼150 K), combined with the absence of any sign of doping-induced superconductivity down to ∼3 K, suggests that the two phases might be competing with each other to determine the electronic ground state of electron-doped MoS2.
Reference-Free Artificial Noise Waveform Design and Cancellation for Secure Transmission

In this paper, we propose a reference-free artificial noise (AN) waveform design and cancellation scheme for single-input-single-output (SISO) wireless secure transmission. First, a system structure with the aid of AN is presented, where we provide a specific method extracting the sign information of each symbol from the desired signal (DS) to form AN at the transmitter. Then, we notice that the legitimate receiver enable to reconstruct the AN from the received signal by almost the same method as the transmitter without AN reference, which reduces the system complexity in practice. Subsequently, the AN cancellation performance and the secrecy capacity at the receiver are analyzed, and their upper bounds are also derived. Finally, simulation results confirm that the proposed reference-free AN design and cancellation scheme can effectively suppress the AN at legitimate receiver, while degrades the signal to noise ratio (SNR) at eavesdropper seriously, which provides impressive secure performance in terms of secrecy capacity.
Hematological Parameters and Short Term Clinical Outcome after ST-elevation Myocardial Infarction

Background: ST-Elevation myocardial infarction is a major public health problem and a leading cause of death both in developed and developing countries. The values of hematological biomarkers were evaluated as predictors of in hospital mortality and complications, in patients with acute coronary syndromes (ACS). This study aimed to draw a relationship between different hematological parameters and short-term clinical result in STEMI cases treated by primary percutaneous coronary intervention. Methods: This prospective research involved 100 participants that had a STEMI and were receiving primary PCI and they were subjected to detailed history, general and local examination, resting surface ECG, baseline laboratory tests, reperfusion, transthoracic echocardiogram and follow up of clinical outcome. Results: After STEMI, there was not significantly different between cases with low and high NLR (P <0.4). There was significantly different between cases with low and high NLR after STEMI, low and high MPV [in heart failure, death and rehospitalization] and after STEMI, in diabetic patients and in NLR between low and high MPV groups after STEMI (P < 0.05), there was no significant statistical difference between patients with low and high PDW and after STEMI. LVEF were significant less in participants had MACE (P <0.036). In stepwise multivariate regression analysis of hematological parameters, NLR and MPV were significant predictive factors of MACE (P < 0.05). Conclusions: Hematological and coagulation parameters may be utilized as diagnostic and prognostic indicators. Early risk classification enables doctors to closely monitor and treat high-risk patients, as well as schedule them for regular follow-ups, helping to the reduction of mortality.
