Article A Secure Data Sharing Based on Key Aggregate Searchable Encryption in Fog-Enabled IoT Environment Cloud server and fog computing have been utilized to manage enormous volumes of data with low service transmission time in Internet of Things (IoT) environment. However, untrustworthy relationships between network entities and cloud server cause a lot of security concerns. Many researches have been studied based on traditional cryptosystems for data sharing systems. But they lead to key management difficulty and do not ensure the data owner's authority by depending on Trusted Third Party (TTP). Therefore, we use key aggregate searchable encryption (KASE), which enables owners to exercise their rights in data management and sharing without the help of TTP and resolves the key management problem. In this paper, we propose a secure data sharing system based on KASE in fog-enabled IoT environment using blockchain. We prove the resistance of the proposed scheme against various attacks through informal analysis and Automated Validation of Internet Security Protocols and Applications (AVISPA) simulation tool. We prove the guarantee of secure mutual authentcation using Burrows-Abadi-Needham (BAN) logic. Furthermore, we compare security features and performance of the proposed scheme with existing schemes through Multiprecision Integer and Rational Arithmetic Cryptographic Library (MIRACL).

Article An All-Nanofiber-Based Substrate-Less, Extremely Conformal, and Breathable Organic Field Effect Transistor for Biomedical Applications Nanofiber-based electronic devices have attracted considerable interest owing to their conformal integration on complicated surfaces, flexibility, and sweat permeability. However, building complicated electronics on nanomesh structure has not been successful because of their inferior mechanical properties and processability. This limits their practical application. To achieve system-level device applications, organic field-effect transistors are one of the key components to be integrated with various sensors. Herein, a successful method for fabricating a biocompatible, ultrathin (≈1.5 µm), lightweight (1.85 g m–2), and mechanically durable all-nanofiber-based organic transistor is reported that can be in conformal contact with curved skin. Furthermore, it is the first development with a substrate-less nanomesh organic field effect transistor. The devices exhibit satisfactory electrical performance, including an on/off value of 3.02 × 104 ± 0.9 × 104, saturation mobility of 0.05 ± 0.02 cm2 V− 1 s− 1, subthreshold slope of 1.7 ± 0.2 V dec–1, and threshold voltage of −6 ± 0.5 V. The mechanism of crack initiation is analyzed, via simulation, to understand the deformation of the nanomesh transistors. Furthermore, active matrix integrated tactile sensors entirely on the nanomeshes is successfully demonstrated, indicating their potential applicability in the field of biomedical electronics. © 2022 Wiley-VCH GmbH.

Article Comparison of Online Patient Reviews and National Pharmacovigilance Data for Tramadol-Related Adverse Events: Comparative Observational Study Background: Tramadol is known to cause fewer adverse events (AEs) than other opioids. However, recent research has raised concerns about various safety issues. Objective: We aimed to explore these new AEs related to tramadol using social media and conventional pharmacovigilance data. Methods: This study used 2 data sets, 1 from patients' drug reviews on WebMD (January 2007 to January 2021) and 1 from the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS; January 2016 to December 2020). We analyzed 2062 and 29,350 patient reports from WebMD and FAERS, respectively. Patient posts on WebMD were manually assigned the preferred terms of the Medical Dictionary for Regulatory Activities. To analyze AEs from FAERS, a disproportionality analysis was performed with 3 measures: proportional reporting ratio, reporting odds ratio, and information component. Results: From the 869 AEs reported, we identified 125 new signals related to tramadol use not listed on the drug label that satisfied all 3 signal detection criteria. In addition, 20 serious AEs were selected from new signals. Among new serious AEs, vascular disorders had the largest signal detection criteria value. Based on the disproportionality analysis and patients' symptom descriptions, tramadol-induced pain might also be an unexpected AE. Conclusions: This study detected several novel signals related to tramadol use, suggesting newly identified possible AEs. Additionally, this study indicates that unexpected AEs can be detected using social media analysis alongside traditional pharmacovigilance data.

Article Design of Blockchain-Based Lightweight V2I Handover Authentication Protocol for VANET Connected vehicle means providing different services, such as advanced driver-assistance systems (ADAS) from vehicles connected to the network. Vehicular ad-hoc networks (VANETs) can support vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications to realize connected vehicle. In VANETs, secure communication must be ensured, as otherwise it can lead to traffic accidents and human injuries. Recently, many studies on V2I authentication have been conducted to guarantee the security of V2I communications. However, recent V2I authentication protocols do not consider the handover situation, and it causes unnecessary computations. As vehicles have limited computing resources, unnecessary computation can lead to overload to the vehicles. In recent years, blockchain-based VANET is an active field of research because it can provide decentralization, data integrity and transparency. Using the strength of the blockchain technology, we design a blockchain-based handover authentication protocol for VANETs. In the proposed protocol, vehicles only perform lightweight computations in handover situations for efficiency of the network. We also conduct the formal analysis such as Burrows-Abadi-Needham (BAN) logic, Real-Or-Random (ROR) oracle model, and Automated Validation of Internet Security Protocols and Applications (AVISPA) simulation to the proposed protocol. We simulate the proposed protocol using network simulator 3 (NS-3) to verify that the proposed protocol is practical. Finally, we compare the computational cost and security features of the proposed protocol with existing protocols to show that the proposed protocol is more secure and efficient.

Article Exceeding 50 mW RMS-Output Magneto-Mechano-Electric Generator by Hybridizing Piezoelectric and Electromagnetic Induction Effects A magneto-mechano-electric (MME) generator with root mean square (RMS) output exceeding 50 mW is demonstrated by integration of a piezoelectric Pb(Mg1/3Nb2/3)O-3-Pb(Zr,Ti)O-3 (PMN-PZT) single crystal and an electromagnetic induction structure to convert a gentle alternating current magnetic field into electricity to operate a high-power consumption multi-functional Internet of Things (IoT) environmental monitoring system. The 2nd resonance bending mode at the cantilever-type hybrid MME generator enabled much higher output power than the conventional 1st resonance mode, which is theoretically investigated by a finite element analysis. The hybridized MME generator can generate a total RMS output power of 60 mW since the output power of the piezoelectric and electromagnetic induction parts is 26.7 and 33.3 mW, respectively, by a magnetic field of 7 Oe at the 2nd harmonic bending mode. The hybrid MME generator is employed to irradiate a red laser as well as to fully charge a commercial 280 mAh LiFePO4 battery. Finally, a self-powered multi-functional IoT environment monitoring system is constructed by integrating the hybrid MME generator, a power management circuit, and a wireless multiple sensing modules. The remarkable output power from the hybridized MME generator enabled the continuous sensing of nine types of ambient information and subsequent transmission of the measured data to a smartphone.

Article Interface Modeling via Tailored Energy Band Alignment: Toward the Electrochemically Stabilized All-Solid-State Li-Metal Battery Interfacial instability between Li-metal anode (LMA) and inorganic solid-state electrolyte (SSE) is a critical issue in all-solid-state Li-metal batteries (ASSLBs). Previous studies have focused on interface modification methodology to achieve long-term cycling stability in ASSLBs. However, strategy establishment without an in-depth understanding of the LMA-SSE interface is limited to a phenomenological solution. Also, the fact that rechargeable batteries are operated by behavior of charges inside electric field is frequently overlooked. Here, it is demonstrated for the first time that interface modeling based on energy band theory does effectively overcome the intrinsic vulnerability of SSE to LMA. The interfacial deterioration, due to undesirable electron transport from LMA to the SSE surface, is precluded by a titanium compound self-induced interlayer (TSI), which forms an interfacial energy barrier. The Li symmetric cell with a TSI successfully maintains its constant overpotential over 1000 cycles and the significantly reduced impedance, whereas the cell having no interface modification exhibits erratic voltage profiles and is easily failed by repetitive charge-discharge process. This newly introduced approach is an informative tool to substantially reinforce the fundamental understanding of interfacial phenomena in all-solid-state batteries. Furthermore, rigorous stability requirements of automotive applications are expected to be fulfilled by the innovative interface modification.

Article Real-Time Monitoring of the Dehydrogenation Behavior of a Mg2FeH6-MgH2 Composite by In Situ Transmission Electron Microscopy Herein, real-time observations of dehydrogenation of a Mg2FeH6-MgH2 composite by means of in situ transmission electron microscopy (TEM) with advanced spatial (approximate to 0.8 angstrom) and temporal (25 frames s(-1)) resolution are reported. Careful control and systematic variations of the reaction temperature and electron dose rate enable detailed and direct visualization of the characteristic decomposition of Mg2FeH6 into Mg and Fe, which occurs on the nanometer scale under optimal experimental conditions defined to minimize the electron-beam-driven Mg oxidation and dehydrogenation that take place in TEM. First, the formation of nanostructured fine Fe clusters in Mg metal and their growth via coalescence during dehydrogenation are verified. Additionally, fine monitoring of the in situ diffraction patterns acquired during decomposition of the composite allows separate evaluations of the desorption kinetics of the two coexisting phases, which confirm the synergetic dehydrogenation of this dual-phase system. It is envisioned that these findings will provide useful guidelines for reducing the gaps between nanoscale and bulk-scale research and designing hydrogen sorption conditions to enable efficient operation of a solid-state hydrogen storage system.

Article Spatial Control of Oxygen Vacancy Concentration in Monoclinic WO3 Photoanodes for Enhanced Solar Water Splitting Oxygen vacancies (OVs) are a mixed blessing for the photoelectrochemical (PEC) water oxidation performance of monoclinic tungsten trioxide (m-WO3) photoanodes. Although it is widely accepted that a moderate concentration of OVs is beneficial for the PEC performance of the m-WO3 photoanodes, this argument assumes a uniform distribution of OVs throughout the m-WO3 crystal. In this case, only the overall concentration of OVs needs to be considered. However, the spatial non-uniformity of OV defects in m-WO3 photoanodes has not been thoroughly examined. In this study, by employing a m-WO3 nanorod array as a model photoanode, the aim is to show that a higher OV concentration near the surface of m-WO3 compared to that in the bulk is advantageous for the PEC performances of this material. In addition, a laser-assisted defect control (LADC) process is employed to manipulate the spatial distribution of OVs in the m-WO3 photoanodes to achieve enhanced PEC performances. Moreover, a one-step laser deposition process is introduced to obtain an ultrathin FeNi oxygen evolution catalyst overlayer on the defect-controlled m-WO3 photoanodes, further improving PEC performance, photostability, and Faradaic efficiency.

Article Water-Insensitive Electron Transport and Photoactive Layers for Improved Underwater Stability of Organic Photovoltaics Water ingress is one of the major environmental stresses to cause the degradation of device performance in organic photovoltaic (OPVs) and is one of the major barriers impeding their commercialization. This work demonstrates that combining the use of a nanoparticle titanium dioxide (np-TiO2) electron transporting layer (ETL) and an all-polymer bulk heterojunction (BHJ) photoactive layer can endow the derived OPV with a much better water resistivity than the commonly employed zinc oxide (ZnO) ETL or polymer:small molecule BHJ blends. Polymer donors/acceptors are first shown to possess better water-immersion than the small molecule counterparts. Hence, the all-polymer blend exhibits the lowest absorbance losses after water immersion among the studied BHJ systems. Furthermore, the result reveals that tailoring the structure of the TiO2 ETL from planar to nanoparticles effectively strengthens the adhesion at the ETL/BHJ interface to prevent physical delamination. Finally, the np-TiO2/all-polymer blend (half-cell) is demonstrated to have superior stability under water immersion, i.e., unchanged morphology and charge carrier transfer, as well as no efficiency changes in the complete cells. This work demonstrates the great potential of the all-polymer blends and np-TiO2 ETL for improving the durability of unencapsulated OPVs under high humidity environments and even water immersion.

Article Biological insights into systemic lupus erythematosus through an immune cell-specific transcriptome-wide association study Objective Genome-wide association studies (GWAS) have identified >100 risk loci for systemic lupus erythematosus (SLE), but the disease genes at most loci remain unclear, hampering translation of these genetic discoveries. We aimed to prioritise genes underlying the 110 SLE loci that were identified in the latest East Asian GWAS meta-analysis. Methods We built gene expression predictive models in blood B cells, CD4(+) and CD8(+) T cells, monocytes, natural killer cells and peripheral blood cells of 105 Japanese individuals. We performed a transcriptome-wide association study (TWAS) using data from the latest genome-wide association meta-analysis of 208 370 East Asians and searched for candidate genes using TWAS and three data-driven computational approaches. Results TWAS identified 171 genes for SLE (p<1.0x10(-5)); 114 (66.7%) showed significance only in a single cell type; 127 (74.3%) were in SLE GWAS loci. TWAS identified a strong association between CD83 and SLE (p<7.7x10(-8)). Meta-analysis of genetic associations in the existing 208 370 East Asian and additional 1498 cases and 3330 controls found a novel single-variant association at rs72836542 (OR=1.11, p=4.5x10(-9)) around CD83. For the 110 SLE loci, we identified 276 gene candidates, including 104 genes at recently-identified SLE novel loci. We demonstrated in vitro that putative causal variant rs61759532 exhibited an allele-specific regulatory effect on ACAP1, and that presence of the SLE risk allele decreased ACAP1 expression. Conclusions Cell-level TWAS in six types of immune cells complemented SLE gene discovery and guided the identification of novel genetic associations. The gene findings shed biological insights into SLE genetic associations.

Article Combinatorial discovery of irradiation damage tolerant nano-structured W-based alloys One of the challenges in fusion reactors is the discovery of plasma facing materials capable of withstanding extreme conditions, such as radiation damage and high heat flux. Development of fusion materials can be a daunting task since vast combinations of microstructures and compositions need to be explored, each of which requires trial-and-error based irradiation experiments and materials characterizations. Here, we utilize combinatorial experiments that allow rapid and systematic characterizations of composition-microstructure dependent irradiation damage behaviors of nanostructured tungsten alloys. The combinatorial materials library of W-Re-Ta alloys was synthesized, followed by the high-throughput experiments for probing irradiation damages to the mechanical, thermal, and structural properties of the alloys. This highly efficient technique allows rapid identification of composition ranges with excellent damage tolerance. We find that the distribution of implanted He clusters can be significantly altered by the addition of Ta and Re, which play a critical role in determining property changes upon irradiation. © 2022 Elsevier B.V.

Article Generalized correlation for predicting the droplet size in a microfluidic flow-focusing device under the effect of surfactant This paper describes an investigation on the dynamic behavior of droplet formation in a microfluidic flow-focusing device (MFFD) under the effect of surfactant using a phase-field method and the Koterweg stress applied in Navier-Stokes equations. The effects of variously important parameters, such as capillary number (Ca-0), water fraction (wf), the viscosity ratio (alpha), and particularly surfactant concentration (c(b)), were examined. Consequently, the numerical results match the experimental ones. Additionally, the droplet formation is significantly affected by the surfactant, and the droplet size decreases with increasing c(b) for the whole range of both wf and Ca-0. Based on the extensive study, the phase diagrams with two main modes, namely, dropping and threading, are provided. A mountain shape of the dropping mode was found, and this mode can be extended for higher wf with the presence of surfactant. In particular, new generalized correlations as a function of wf, Ca-0, and c(b) are first proposed for predicting quickly and effectively the droplet size. Furthermore, the droplet formation depends significantly on alpha. With the presence of surfactant, smaller size of the droplet forms and the threading mode occurs at very high alpha. The results obtained in this study are very useful for understanding the dynamic behavior of droplet formation in MFFDs, which can be used in potential applications such as biomedical and drug delivery systems.

Article Numerical investigation of the effect of tracheostomy on flow and particle transport characteristics in human airways Tracheostomy is a typical surgical procedure that has been widely practiced to address airway-related difficulties, such as airway obstruction or chronic conditions, that require long-term supportive ventilation. However, it may result in symptoms that detrimental to respiratory system. Computational fluid dynamics (CFD) is a noninvasive and efficient approach for observing the effects of tracheostomy. In this study, we introduced a CFD framework that can reveal the effects of tracheostomy tube insertion based on a comparison with the airflow of a normal airways. An automatic transformation method was developed using a patient's anatomical information to combine subject-specific airways with an artificial tracheostomy tube geometry and an idealized upper airway geometry for later comparison of characteristics of airflow and particle transport. The CFD scheme used for flow simulation in lungs was employed to achieve the behaviors of airflow. The tracheostomy tube generates a jet flow, resulting in twice greater wall shear stress (WSS) and 30 times greater viscous dissipation in the trachea compared to normal airway. The tracheostomized airway induces an intense turbulent jet, which enhances chaotic motion of the particles therein and allows particles to deposit more frequently on the surface. Subsequently, an increase in particle deposition is observed on the central airway's surface. The variation of pressure between inspiration and expiration phase was twice greater and the airflow resistance was also significantly higher compared to normal airway, implying the greater work of breathing. The novel framework could evaluate the efficiency and potential complications in performing tracheostomy beforehand by observing airflow behaviors.

Article Ricci-Bourguignon solitons on real hypersurfaces in the complex hyperbolic quadric By using the property of generalized pseudo-anti commuting Ricci tensor, that is, Ric phi + phi Ric = f phi, for real hypersurfaces in the complex hyperbolic quadric Qin*, we give a complete classification of Hopf Ricci-Bouguignon soliton real hypersurfaces in the complex hyperbolic quadric Q(m)*. Next as an application we obtain a classification of gradient Ricci-Bouguignon solitons on Hopf real hypersurfaces in Q(m)*.
