AbstractPerovskites are promising light emitters that can cover broad‐range emissions over the entire visible spectrum. However, few studies have focused on uncommon wavebands, such as far‐red emission of 700–750 nm that has broad applications in biology, horticulture lighting, optogenetics, etc. Here, a strategy is demonstrated to achieve high‐performance far‐red perovskite light‐emitting diodes (PeLEDs) through antisolvent engineering. First, 1,3,5‐tris(1‐phenyl‐1H‐benzimidazole‐2‐yl) benzene (TPBi) is introduced into n‐i‐p perovskite matrix not only to passivate the defects but also to balance carrier mobility as well as adjust the energy level alignment between perovskite and the electron transport layer. The n‐type TPBi can prevent hole carriers’ movements in perovskite light emitters and enhance electron injection. Furthermore, the incorporation of TPBi uplifts the Fermi energy level of perovskites by 0.32 eV as well as diminishes the conduction band offset between zinc oxide (ZnO) and the perovskite emitters, hence alleviating the accumulation of charges at the interface. Consequently, the PeLEDs with TPBi‐modified perovskite emitters show an invariable far‐red emission peak at around 735 nm with a champion external quantum efficiency of 14.22%. This work makes up the far‐red emission of perovskite light‐emitting devices and boosts latent capacity of PeLEDs for future application.

Published: January 2023

AbstractCarbon fiber reinforced composites have attracted lots of attention in many fields. However, on account of the poor infiltration of resin to carbon fiber, the weak interface performance between fiber and resin has been restricting the interface properties of composites. In recent progress, the review attaches more importance to the introduction of the third phase monomer, which mainly uses physical and chemical methods to assemble nanomaterials (such as carbon nanotubes, graphene, etc.) on the carbon fiber surface to modify the interface structure of the carbon fiber reinforced composites, and all of them have been demonstrated in this paper. Furthermore, the effects of introducing nanomaterials on the structure of the fiber/resin interface and the relationship between multi‐scale interface structure and properties have been investigated. It can be seen that the design idea of researchers mainly uses one or more theories to improve the interface properties of carbon fiber reinforced composites, such as transition layer, chemical bonding, mechanical interlocking, infiltration, diffusion, and adsorption. In brief, this work provides some novel insights for the preparation of carbon fiber reinforced composites with excellent interlaminar shear strength.
A study on coatability of marble dust on metal substrates
Authors: Nayak S. K. , Satapathy A. , Mantry S. 
Published: January 2023

AbstractMarble dust is a hazardous construction/industrial waste generated during the extraction, cutting and polishing of marble‐producing rocks. The present work explores the potential of marble dust to be used as a coating material on metal substrates. For this, the high‐velocity oxy‐fuel (HVOF) spraying route is adopted to deposit marble dust coatings on four different metallic substrates: mild steel, inconel, aluminum, and copper. Liquefied petroleum gas is used as the fuel and nitrogen as the carrier gas while the coating deposition is performed by varying the spray distance over a range from 50 mm to 250 mm. The coating microstructure is studied using a scanning electron microscope (SEM) and the developed phases are identified using an x‐ray diffractometer. The developed coatings are characterized in terms of deposition efficiency, coating thickness and adhesion strength. It is found that the coatings exhibit fairly good interfacial adhesion and thickness values that varied quite significantly with the spray distance. Maximum deposition efficiency of about 68 % is obtained for the copper substrate when the deposition is performed at a spray distance of 100 mm. This experimental investigation thus shows that despite being a waste, marble dust is eminently coatable on several metallic substrates.

AbstractThis study reports the results of a preliminary study of manufacturing aluminum–potassium feldspar metal matrix composites including its castability and mechanical properties. The material was composed considering 0.25 %, 0.5 %, and 0.75 % additive ratios to examine the impact of the amount of potassium feldspar on the material and mechanical properties of the manufactured aluminum metal matrix composite material. Aluminum alloy (A356) was utilized as the matrix of the composition. The composite material was manufactured by the stir casting technique. The modulus of elasticity, yield strength, tensile strength, elongation, density, and quality index of the material parameters was taken into account to determine the materials′ practicality. The preliminary results indicated that potassium feldspar is a promising mineral to be utilized as an additive for aluminum metal matrix composites since it has a positive impact on mechanical properties. By optimizing the casting parameters, the positive aspects of the potassium feldspar may make the material more practical to be utilized in vast engineering applications.

AbstractThe effect of thickness and chemical composition on the electrical power and thermal resistance of dilatometric specimens heated by Joule heating are analyzed in different steels, using stepped tests of constant temperature and electrical current. In the stepped constant temperature tests, the electric current necessary to maintain the target temperature in a specific time is measured, while in the electric current tests the electrical current is maintained until the maximum temperature stabilizes. The results show that the electrical power behaves linearly with the thickness associated with the transfer area, while the thermal resistance behaves potentially; both values depend on the chemical composition due to electrical resistivity. The steels with a higher concentration of alloying elements have a better response to Joule heating. However, thickness is the parameter that most influences electrical power due to changes in transfer area and electrical current density, as well as in the mass of the specimen to be heated. Finally, based on the results obtained, predictions are realized for the design of thicker specimens, maintaining the observed behavior; i. e., as the thickness of the specimen increases, the increase in electrical power and thermal resistance is maintained.
Characterization and evaluating the mechanical performance of halloysite nanotubes reinforced acrylonitrile butadiene styrene/polycarbonate composites exposed to aggressive environmental conditions

Published: January 2023

AbstractDeveloping light weight polymer based composites dispersed with novel reinforcements which can function well in the presence of aggressive environments is an active research field in the materials engineering. Hence, in the current work, halloysite nanotubes (1 %, 2 %, 4 %, 6 %, 8 % and 10 % by weight) were reinforced into acrylonitrile butadiene styrene/polycarbonate blend and the role of reinforcing phases on the mechanical performance under aggressive environmental conditions has been evaluated. Hardness was measured as gradually increased in the composites with the increased content of the reinforcements. Impact strength of the composites was observed as increased in the composites up to 4 % reinforcement and further decreased. Increased strength was measured for the composite up to 2 % reinforcement. Ductility of the composites was decreased as reflected form the decreased % of elongation with the higher fraction of reinforcements due to induced brittleness. The composites were exposed to diluted sulfuric acid for 3 h and 6 h at 60 °C and then subjected to tensile loading. With the increased time of exposure, composites with 1 % and 2 % reinforcement exhibited relatively better performance.

AbstractBackgroundThe concept of a myopathy with associated tremor (“myogenic tremor”) in humans has been previously described for specific MYBPC1 (Myosin‐Binding Protein C) variants. Here we report for the first time an individual with tremor who was found to have a de‐novo likely pathogenic variant in Myosin Heavy Chain 7 (MYH7).We provide a detailed electrophysiological characterization of the tremor syndrome in a human individual with a myopathy and this pathogenic MYH7 variant to provide further insight in the phenotypic spectrum and pathomechanism of myogenic tremors in skeletal sarcomeric myopathies.MethodsElectromyographic recordings were obtained from facial muscles, as well as bilateral upper and lower extremities.Results10 to 11 Hz activity was observed in the face and extremities during recordings with muscle activation. There were intermittent episodes of significant left–right coherence that would modulate across muscle groups throughout the recording, but no coherence between muscles at different levels of the neuraxis.ConclusionsA possible explanation for this phenomenon is that the tremor originates at the sarcomere level within muscles, which is then picked up by muscle spindles and leads to activating input to the neuraxis segment. At the same time, the stability of the tremor frequency does suggest the presence of central oscillators at the segmental level. Thus, further studies will be needed to determine the origin of myogenic tremor and to better understand the pathomechanism.
Advertising strategies of competing firms considering consumer privacy concerns

Published: January 2023

AbstractTargeted advertising based on consumers' purchase history is the most prevalent choice for firms; however, its effectiveness is affected by an increase in consumer privacy concerns. We established a two‐period game model to analyze firms' equilibrium advertising strategies, pricing strategies, and profits when a segment of consumers is unwilling to provide their purchase information owing to privacy concerns. Based on the equilibrium results, some valuable managerial insights are suggested for competing firms. Firms should consider the proportion of privacy‐sensitive consumers and advertising costs when developing advertising strategies. Targeted advertising is not an optimal choice invariably.
Radiative cooling scale method for correcting hourly surface air temperature error in numerical weather prediction models
Authors: Ueyama Hideki 
Published: January 2023

AbstractGlobally, a variety of numerical weather prediction (NWP) models are employed by national agencies. However, the derived outputs from these models are generally inadequate for precise cultivation management due to bias error. This study uses observational data acquired over several months to develop an equation for correcting surface air temperature (SAT) error in NWP model outputs. With the proposed method, model outputs are converted into potential temperature to cancel the influence of differences between computational elevation and real elevation. The potential temperature errors in the NWP model outputs are corrected using a linear regression equation in which a radiative cooling scale (RCS) serves as the independent variable. The RCS is computed using air temperature observed at a nearby meteorological observation station, together with upper‐level pressure data from the NWP model. Versions of the correction models are developed for specific situations: day, night, and upper‐level meteorology, classified into six groups. In an application of the proposed method, the root mean square error (RMSE) of the corrected SAT output from a global spectral model operated by the Japan Meteorological Agency (JMA) was 1.2–1.6 K; the RMSE of the corrected SAT output from a nonhydrostatic model operated by the JMA was 1.2–1.5 K. The proposed method corrected the NWP model SAT output errors to a level of accuracy similar to that of data corrected using the Kalman filtering technique without the requirement for constant observation at the target site.

AbstractAimsTo explore the associations between sociodemographic and clinical data, the patient's knowledge and skills, and relationship to healthcare professionals with leakage from an ostomy.DesignCross‐sectional.MethodsThis study included 160 patients with a colostomy, ileostomy, or urostomy. Leakage was the dependent variable and was assessed by self‐report. Sociodemographic and clinical data and the Ostomy Adjustment Scale subscores, ‘knowledge and skills’ and ‘health care professionals’ were independent variables. Spearman's rho and multivariate partial least squares regression analysis were used to estimate possible factors associated with leakage.ResultsOf the participants, 13.8% had leakage weekly or more often, 16.3% more often than once a month and 37, 5% had leakage more seldom than once a month. The most important risk factors for leakage were (1) having an ostomy placement that does not meet international guidelines, (2) not having an optimal relationship with health professionals, (3) having a diagnosis other than cancer, (4) not having proper knowledge and skills in ostomy care, (5) not having a colostomy, (6) having a convex baseplate, (7) having an oval ostomy, and (8) being dependent on others for ostomy care. The independent variables in the PLS‐ model explained 31% of the variance in leakage.Patient or Public ContributionWe thank the patients in the user panel for their help during the study.

Published: January 2023

AbstractObjectiveInhaled corticosteroids (ICS) have been demonstrated to be associated with voice changes. The goal was to determine the strength of the association between ICS use and a diagnosis of dysphonia made by an otolaryngologist and to determine whether inhaler particle type or medication type influenced this risk.Study DesignA case‐control study from 2018 to 2020.SettingUrban academic medical system.MethodsAdult patients with dysphonia diagnosed by an otolaryngologist, and control patients matched on age, gender, race, and health status, were included. Exposure to ICS was assessed, and the odds ratio (OR) of the association of ICS with dysphonia was calculated.ResultsA total of 6551 cases and 6551 matched controls were included. We found that ICS use was significantly associated with dysphonia (OR: 5.11, 95% confidence interval: 4.23‐6.17, p < .001). Subset analyses demonstrated no significant differences between inhaler particle types or specific active medications.ConclusionThis study emphasizes the importance of identifying ICS use in the evaluation and treatment of patients with dysphonia.

AbstractObjectiveDefining a clinician's ability to perceptually identify mass from voice will inform the feasibility, design priorities, and performance standards for tools developed to screen for laryngeal mass from voice. This study defined clinician ability of and examined the impact of expertise on screening for laryngeal mass from voice.Study DesignTask comparison study between experts and nonexperts rating voices for the probability of a laryngeal mass.SettingOnline, remote.MethodsExperts (voice‐focused speech‐language pathologists and otolaryngologists) and nonexperts (general medicine providers) rated 5‐s/i/voice samples (with pathology defined by laryngoscopy) for the probability of laryngeal mass via an online survey. The intraclass correlation coefficient (ICC) estimated interrater and intrarater reliability. Diagnostic performance metrics were calculated. A linear mixed effects model examined the impact of expertise and pathology on ratings.ResultsForty clinicians (21 experts and 19 nonexperts) evaluated 344 voice samples. Experts outperformed nonexperts, with a higher area under the curve (70% vs 61%), sensitivity (49% vs 36%), and specificity (83% vs 77%) (all comparisons p < .05). Interrater reliability was fair for experts and poor for nonexperts (ICC: 0.48 vs 0.34), while intrarater reliability was excellent and good, respectively (ICC: 0.9 and 0.6). The main effects of expertise and underlying pathology were significant in the linear model (p < .001).ConclusionClinicians demonstrate inadequate performance screening for laryngeal mass from voice to use auditory perception for dysphonia triage. Experts' superior performance indicates that there is acoustic information in a voice that may be utilized to detect laryngeal mass based on voice.
Physical, mechanical, viscoelastic, and morphological properties of poly(lactic acid)/ethylene‐co‐vinyl acetate blend reinforced with silicon carbide nanoparticles

Published: January 2023

AbstractPhase morphology, mechanical properties, melting and crystallinity, as well as the dynamic viscoelastic properties of poly(lactic acid) (PLA)/ethylene‐co‐vinyl acetate (EVA) (80/20) blend containing 0–3 wt% nano‐silicon carbide (SiC) were studied. Morphological observations revealed the localization of nano‐SiC particles around the EVA droplets with the consequence of a fall in the size of EVA dispersed phase in the nanocomposites compared with the unfilled blends. The mechanical characterization results showed a gradual increase in the elastic moduli and yield stress with increasing nano‐SiC content in the nanocomposites, while the strain at break and Izod impact strength were steadily decreased. The nano‐SiC particles served as nucleating agents for crystallization of the PLA matrix from the molten state. The crystallinity of the PLA matrix in the nanocomposites was slightly reduced compared with that of the unfilled blend. The dynamic mechanical thermal analysis results showed a gradual increase in the glass transition temperature of PLA matrix together with a steady decline of damping capability as the nano‐SiC content in the nanocomposite was increased. The dynamic rheological data demonstrated enhanced complex viscosities and storage moduli of the nanocomposites in a direct proportion to the nanofiller loading, specially at the low‐frequency region. The changes occurred in the various properties of the fabricated nanocomposites were interpreted in terms of alteration in the phase morphology and the physical interactions of the nano‐SiC particles with the blend's components.

Published: January 2023

AbstractA new energetic cocrystal of 2,4,6,8,10,12‐hexanitrohexaazaisowurtzitane (CL‐20) and 1,4‐dinitropyrazole (1,4‐DNP) with a 1 : 1 molar ratio was prepared by slow solvent evaporation. This cocrystal belongs to monoclinic system with P21/c space group formed mainly by the CH−O, CH−N, and NO2−π interactions through analyzing the structures and interactions. CL‐20/1,4‐DNP cocrystal has a melting point of 132 °C with a decomposition temperature of 253 °C, showing an excellent stability. Moreover, the impact sensitivity of the cocrystal (13.5 J) is similar to that of 1,1‐diamino‐2,2‐dinitroethene (FOX‐7, 14 J), a typical insensitive energetic material, indicating a favorable low sensitivity. Furthermore, the detonation performances of the cocrystal (8954 m/s, 35.90 GPa) are slightly superior to that of 1,3,5‐trinitro‐1,3,5‐ triazacyclohexane (RDX, 8877 m/s, 34.94 GPa), suggesting that CL‐20/1,4‐DNP cocrystal has an excellent detonation property. Therefore, the CL‐20/1,4‐DNP cocrystal may be an attractive new explosive with a good comprehensive performance and thus, may be used as a promising candidate instead of RDX for safety ammunitions in future.
Fractional‐order integral terminal sliding‐mode control for perturbed nonlinear systems with application to quadrotors
Authors: Labbadi Moussa , Defoort Michael , Incremona Gian Paolo , Djemai Mohamed 
Published: January 2023

AbstractIn this article, a novel fractional‐order recursive integral terminal sliding mode (FORITSM) control is proposed for nonlinear systems in the presence of external disturbances with unknown bounds. The proposed control approach provides an easy‐to implement solution capable of zeroing the sliding variable in a finite‐time (FnT) by adding a fractional‐order command filter. Moreover, the reaching phase is eliminated, and FnT convergence of the system states is proved. The proposed technique has also a chattering alleviation property, which is beneficial for practical cases, as the control of quadrotor UAVs presented in the article. Finally, a simulation case study on a quadrotor system is illustrated to show the effectiveness of the proposed FORITSM control, also with respect to classical methods.
Alexander Bogdanov and the question of unity: An emerging research agenda
Authors: Şenalp Örsan , Midgley Gerald 
Published: January 2023

AbstractIn this paper, we propose a research agenda to support the recovery of Alexander Bogdanov's philosophical and systemic thinking that culminated in his magnum opus,Tektology. Our main reason for doing so is to re‐address enduring questions about the unity of science and the unity of the systems paradigm. Since the turn of the new millennium, there has been renewed interest in the ideal of the unity of science. General system theory (GST), cybernetics and complexity science are three significant intellectual sources inspiring this renewal. It is not unusual for these ideas to be grouped under the umbrella termssystems scienceorsystems thinking, which are two ways to present a singlesystems paradigm, and we will explain why its “unity” is both necessary and problematic. Bringing Bogdanov's work back to address the unity question can help us to progress toward unity in diversity.
