Motivating Collaborative Consumption in Fashion: Consumer Benefits, Perceived Risks, Service Trust, and Usage Intention of Online Fashion Rental Services

This study explored the conceptual constructs of consumer benefits and perceived risks of online fashion rental services (Online FRS) and their impacts on usage intention towards Online FRS. The mediating roles of perceived risks and service trust were examined in this research. A survey was performed on female shoppers between the ages of 20–30 residing in a metropolitan area. Results of this research were as follows: (1) The results analyzing the sub-dimension of benefits (Reasonable cost, Wearing at right time, place and occasion (TPO), Space Saving, Entertaining, Product Variety, Style Conformity) and perceived risks (Financial, Performance, Social) clearly presented factorial structures. (2) Reasonable cost, Style Conformity, and Product Variety showed significantly positive influences on usage intentions towards online fashion rental services; in addition, Financial, Performance, and Social risks of rental services had a negative effect on usage intentions. (3) Service trust and consumer perceptions of Financial and Performance risks had important mediating roles in the relationship between consumer benefits and usage intentions towards Online FRS. This study highlighted that consumer benefits, perceived risks, and service trust should be registered among consumers to boost usage intentions towards Online FRS.
Fuzzing the Internet of Things: A Review on the Techniques and Challenges for Efficient Vulnerability Discovery in Embedded Systems

With a growing number of embedded devices that create, transform, and send data autonomously at its core, the Internet of Things (IoT) is a reality in different sectors, such as manufacturing, healthcare, or transportation. With this expansion, the IoT is becoming more present in critical environments, where security is paramount. Infamous attacks, such as Mirai, have shown the insecurity of the devices that power the IoT, as well as the potential of such large-scale attacks. Therefore, it is important to secure these embedded systems that form the backbone of the IoT. However, the particular nature of these devices and their resource constraints mean that the most cost-effective manner of securing these devices is to secure them before they are deployed, by minimizing the number of vulnerabilities they ship. To this end, fuzzing has proved itself as a valuable technique for automated vulnerability finding, where specially crafted inputs are fed to programs in order to trigger vulnerabilities and crash the system. In this survey, we link the world of embedded IoT devices and fuzzing. For this end, we list the particularities of the embedded world as far as security is concerned, we perform a literature review on fuzzing techniques and proposals, studying their applicability to embedded IoT devices and, finally, we present future research directions by pointing out the gaps identified in the review.
Transdermal Transport In Vitro of Domperidone by Compartmental Modeling Approach

Transdermal delivery can be alternatively chosen for domperidone to improve its low oral bioavailability. Development drugs into transdermal formulation need information about the transport mechanism of the drug. The purpose of this study was to develop models of domperidone transdermal transport in vitro based on compartmental modeling for understanding the domperidone transport mechanism. Domperidone solution (0,5 g/L in a citric buffer, pH 5) was filled into the donor compartment. The comparative study also conducted to examine the effect of different pH on domperidone transdermal transport in pH 1 (4g/L in 0,1 M HCl). The shed snake-skin and cellophane membrane were pretreated for 1 hour with chemical enhancers (oleic acid in propylene glycol) and assembled between the donor and the receptor compartment of the vertical diffusion cell. The receptor compartment was filled in with phosphate-buffered saline at a pH of 6.8. The permeation study was performed for 8 hours. Samples concentration was assayed by the UV-Spectrophotometry method. The cumulative permeation profiles of domperidone were analyzed using WinSAAM. Three and four-compartmental models were proposed with the one lag compartment. The evaluation of the appropriate number of compartments in the transport model was examined based on the visual goodness of fit (GOF) and the Corrected Akaike’s Information Criterion (AICc) values. Four-compartmental models with one lag compartment were the best model describing percutaneous domperidone transport either in pH donor of 5 or pH 1. The model indicates domperidone transport follows into two parallel routes, including a lag compartment.
DNA-Based Nanotemplate Directed In Situ Synthesis of Silver Nanoclusters with Specific Fluorescent Emission: Surface-Guided Chemical Reactions

DNA-hosted silver nanoclusters (AgNCs) are a set of metallic fluorescent nanodots that possess high quantum yields and photostability. Here, we show the in situ hosted synthesis of AgNCs by single-stranded DNA preorganized on the self-assembled DNA nanostructure templates, which results in the site-specific formation of AgNCs with the specific fluorescence wavelengths. The excitation/emission properties of AgNCs were tuned by adjusting the distance between nucleation site and the template, the template configuration, and the location of the nucleation site on the template. Mass spectra analysis of AgNC products was performed to study the cluster sizes. The 5′ and 3′ ends of freely diffusing and template-supported host strands were labeled with a donor and an acceptor, and the FRET efficiency was evaluated to reveal the conformations of the host strands and their complexes with Ag+. It is indicated that the rigid template guided the synthetic pathway toward the preferential synthesis of AgNCs with a specif.
Direct determination of the area function for nanoindentation experiments

The determination of a suitable correction for tip blunting is crucial in order to obtain useful mechanical properties from nanoindentation experiments. While typically the required area function is acquired from the indentation of a reference material, the direct imaging by suitable methods is an interesting alternative. In this paper, we investigate the applicability of confocal laser scanning microscopy (CLSM), atomic force microscopy (AFM), and self-imaging by scanning a sharp silicon tip using the scanning probe microscopy extension of the nanoindentation system and compare the results to the area function obtained by the indentation of fused silica. The important tip characteristics were determined by various methods based on the analysis of the obtained 3D data sets. It was found that the suitability of CLSM and AFM depend on the resolution and the operation mode, respectively. While for these methods only limited consistency of the determined tip characteristics was found, self-imaging resulted in an excellent overall agreement.
Diagenetic Trends of Synthetic Reservoir Sandstone Properties Assessed by Digital Rock Physics

Quantifying interactions and dependencies among geometric, hydraulic and mechanical properties of reservoir sandstones is of particular importance for the exploration and utilisation of the geological subsurface and can be assessed by synthetic sandstones comprising the microstructural complexity of natural rocks. In the present study, three highly resolved samples of the Fontainebleau, Berea and Bentheim sandstones are generated by means of a process-based approach, which combines the gravity-driven deposition of irregularly shaped grains and their diagenetic cementation by three different schemes. The resulting evolution in porosity, permeability and rock stiffness is examined and compared to the respective micro-computer tomographic (micro-CT) scans. The grain contact-preferential scheme implies a progressive clogging of small throats and consequently produces considerably less connected and stiffer samples than the two other schemes. By contrast, uniform quartz overgrowth continuously alters the pore space and leads to the lowest elastic properties. The proposed stress-dependent cementation scheme combines both approaches of contact-cement and quartz overgrowth, resulting in granulometric, hydraulic and elastic properties equivalent to those of the respective micro-CT scans, where bulk moduli slightly deviate by 0.8%, 4.9% and 2.5% for the Fontainebleau, Berea and Bentheim sandstone, respectively. The synthetic samples can be further altered to examine the impact of mineral dissolution or precipitation as well as fracturing on various petrophysical correlations, which is of particular relevance for numerous aspects of a sustainable subsurface utilisation.
Improving Performance of Compact EMI Filters by Using Metallic and Ferrite Sheets

Magnetic coupling between components in compact electromagnetic interference filters is one of the main effects that undermine their ability to reduce conducted emissions of power converters at frequencies above several hundreds of kilohertz or a few megahertz. This article analyzes and compares the performance of two different shielding strategies based upon the use of copper bands (high-conductivity material) and flexible ferrite sheets (high-permeability material) to improve the attenuation provided by electromagnetic interference filters. We make use of electromagnetic simulations, measurements, and modeling with a circuit model of the filter to identify the causes of the limited shielding performance of high-conductivity materials and to quantify the reductions in the mutual inductances between the components of the filter that can be obtained by using a smart arrangement of the shielding structures that is able to overcome these limitations while preserving the compactness of the filter. We also describe a design strategy for electromagnetic interference filters which maximizes the benefits of the proposed shielding techniques. Measurements on several filter prototypes demonstrate that the shielding techniques proposed here can provide 20–30 dBs increase in the attenuation provided at high frequencies by the electromagnetic interference filter for differential mode noise.
The enhancement of reactive red 24 adsorption from aqueous solution using agricultural waste-derived biochar modified with ZnO nanoparticles

In this study, two types of agricultural wastes, sugarcane bagasse (SB) and cassava root husks (CRHs), were used to fabricate biochars. The pristine biochars derived from SB and CRHs (SBB and CRHB, respectively) were modified using ZnO nanoparticles to generate modified biochars (SBB-ZnO and CRHB-ZnO, respectively) for the removal of Reactive Red 24 (RR24) from stimulated wastewater. Batch experiments were performed to evaluate the effects of ZnO nanoparticles' loading ratio, solution pH, contact time, and initial RR24 concentration on the RR24 adsorption capacity of biochars. The RR24 adsorption isotherm and kinetic data on SBB, SBB-ZnO3, CRHB, and CRHB-ZnO3 were analyzed. Results indicate that SB- and CRH-derived biochars with a ZnO nanoparticle loading ratio of 3 wt% could generate maximum adsorption capacities of RR24 thanks to the double growth on the BET surface of modified biochars. The RR24 adsorption capacities of CRHB-ZnO3 and SBB-ZnO3 reached 81.04 and 105.24 mg g−1, respectively, which were much higher than those of pristine CRHB and SBB (66.19 and 76.14, respectively) at an initial RR24 concentration of 250 mg L−1, pH 3, and contact time of 60 min. The adsorption of RR24 onto biochars agreed well with the pseudo-first-order model and the Langmuir isotherm. The RR24 adsorption capacity on modified biochars, which were reused after five adsorption–desorption cycles showed no insignificant drop. The main adsorption mechanisms of RR24 onto biochars were controlled by electrostatic interactions between biochars' surface positively charged functional groups with azo dye anions, pore filling, hydrogen bonding formation, and π–π interaction.
The Mediating Role of Internalizing Problems Between Peer Victimization and Dating Violence Victimization: A Test of the Stress Generation Hypothesis

Peer victimization and dating violence are highly prevalent among adolescents. Those two forms of victimization are notably associated with heightened levels of internalizing problems. The stress generation hypothesis stipulates that depressive cognitions and behaviors may generate interpersonal stressors for depressed individuals. It has thus been hypothesized that victims of peer victimization may experience higher levels of internalizing problems, which in turn, may render them more at risk of experiencing dating violence victimization. We used a longitudinal design with three waves from the Quebec Youth’s Romantic Relationships Survey (n = 4,923). Participants (59.6% girls, aged between 14 and 18 years old) reported their experiences of dating violence victimization, peer victimization and psychological distress. A cross-lagged panel analysis was performed to test the mediational effect of psychological distress between peer victimization and dating violence while controlling for age and gender. The interaction effect of gender in the model was also tested. The longitudinal relationship between peer victimization and dating violence victimization was significantly mediated by internalizing problems. This result thus supports the stress generation hypothesis. No interaction effect of gender was observed in the model, thus suggesting that this relationship does not change as a function of gender. This study offers to practitioners in the area of prevention and intervention for peer victimization and dating violence a different way of tackling the problem of revictimization. Indeed, our findings revealed that internalizing problems were longitudinally associated with subsequent relational problems, when occurring after being victimized. Therefore, addressing internalizing problems instead, or in addition to prevention or intervention efforts to stop victimization may help in reducing revictimization rates.
The Strategy of Vaccination and Global Pandemic: How Framing May Thrive on Strategy During and After Covid-19

Purpose: Little is known about the framing that decision-makers use to generate commitment from all engaged with vaccinating programs or their effects and limitations in different contexts. This preliminary study addresses this research gap through an empirical study of the Polish national vaccination program against COVID-19. Approach/Methodology/Design: This paper's insights have emerged iteratively by considering both theory and the empirical case based on vaccination against COVID-19 program analysis. This approach is consistent with an abductive approach. Findings: A study revealed a need to use framing in developing and implementing vaccination strategies. Lack of framing in strategic communication of vaccination leads to the potentially radical suggestion that government should change their current vaccination information policy if they want to avoid poor outcomes. The findings make three contributions. First, they illustrate how framing can influence engagement to multiple goals; Second, they contribute to grounding framing theory within public management by showing how framing may use across contexts; Third, they elaborate the importance of framing in strategic programs. Practical Implications: The article brings several valuable pieces of information that can be the base material and reference to further research. It provides practical tips. Originality/Value: There are several studies on strategy or framing; however, the research question – whether the government's vaccination strategy against COVID-19 uses framing to shape the right message to increase public confidence in the vaccination program was without an answer. It is the first such research in the World.
MYC amplifies gene expression through global changes in transcription factor dynamics.

The MYC oncogene has been studied for decades, yet there is still intense debate over how this transcription factor controls gene expression. Here, we seek to answer these questions with an in vivo readout of discrete events of gene expression in single cells. We engineered an optogenetic variant of MYC (Pi-MYC) and combined this tool with single-molecule RNA and protein imaging techniques to investigate the role of MYC in modulating transcriptional bursting and transcription factor binding dynamics in human cells. We find that the immediate consequence of MYC overexpression is an increase in the duration rather than in the frequency of bursts, a functional role that is different from the majority of human transcription factors. We further propose that the mechanism by which MYC exerts global effects on the active period of genes is by altering the binding dynamics of transcription factors involved in RNA polymerase II complex assembly and productive elongation.
Religious Affiliation and Conceptions of the Moral Domain

What is the relationship between religious affiliation and conceptions of the moral domain? Putting aside the question of whether people from different religions agree about how to answer moral questions, here we investigate a more fundamental question: How much disagreement is there across religions about which issues count as moral in the first place? That is, do people from different religions conceptualize the scope of morality differently? Using a new methodology to map out how individuals conceive of the moral domain, we find dramatic differences among adherents of different religions. Mormon and Muslim participants moralized their religious norms, while Jewish participants did not. Hindu participants in our sample did not seem to make a moral/non-moral distinction of the same kind. These results suggest a profound relationship between religious affiliation and conceptions of the scope of the moral domain.
Magnetic stability against calcining of microwave-synthesized CoFe2O4 nanoparticles

High quality CoFe2O4 nanoparticles were synthesized using a one-pot, microwave assisted method, that allows forming stable colloidal solutions in alcoholic solvents, as required for the preparation by Chemical Solution Deposition of hybrid nanocomposite ferromagnetic-high Tc YBa2Cu3O7 superconducting films or devices. We have investigated how the thermal process necessary for the preparation of such epitaxial nanocomposites, involving high temperatures (800 °C) and oxygen partial pressures (1 atm), affects the structure and magnetic properties of the isolated nanoparticles. The NPs were fully characterised by XRD, SQUID, STEM-EELS and XMCD at four different stages of the thermal process. Results show that, despite intermediate changes in the cation distribution occur during the process, the final NP magnetization is stable against the thermal treatment. This result opens up perspectives for the preparation of hybrid YBCO films with embedded magnetic NPs using low-cost chemical-solution methods.
Applying homotopy perturbation method to provide an analytical solution for Newtonian fluid flow on a porous flat plate

This research work is going to apply the homotopy perturbation method to solve the problem of flowing Newtonian fluid on a flat plate. For this purpose, initially, the problem, including the governing equations and boundary conditions, is defined, and after that, the considered assumptions to solve the defined problem are introduced. Next, the working principle of the homotopy perturbation method is described, and then, the way to obtain the analytical solution using the homotopy perturbation method is presented, and finally, the accuracy of the proposed analytical solution in comparison to the numerical approach is compared for validation. Both momentum and energy equations are solved. The maple software program is utilized for carrying out the mathematical calculations, while the validation is done using the profiles for stream function, velocity distribution, stress, and dimensionless temperature as the key indicators related to the solution. The conducted comparison shows that the analytical solution provided by the homotopy perturbation method is able to predict all the important performance criteria for the problem very well, and therefore, the homotopy perturbation method has a strong potential to be employed for providing the analytical solution for such problems.
Keeping Up with Media Multitasking: An Eye-Tracking Study among Children and Adults to Investigate the Impact of Media Multitasking Behavior on Switching Frequency, Advertising Attention, and Advertising Effectiveness

Abstract Multitasking with media is increasingly popular among all age groups. Previous research has revealed that this media consumption behavior affects the way people respond to advertising messages, but such research thus far has predominantly focused on young adults. This study, using eye-tracking technology, compares how children (8 to 12 years) and adults (18 to 65 years) navigate their attention when simultaneously using television and Internet content, and further investigates the implications for cognitive (i.e., brand recognition) and attitudinal (i.e., advertising irritation) advertising outcomes. A 2 × 2 (age category: children versus adults; task: single medium tasking versus media multitasking) between-subjects experiment was conducted (N = 121). The results show that children switch more between different media than adults, but this switching does not affect advertising outcomes in turn. Furthermore, both children and adults devote less attention to the ad when media multitasking compared to single tasking. There was a positive effect of attention on brand recognition but not on ad irritation. In sum, this study suggests that children are more distracted than adults when media multitasking but respond similarly to advertising embedded in the media. In particular, media multitasking lowers advertising attention for both children and adults, which in turn decreases brand recognition.
Correlation between crystal structure and magnetism in PLD grown epitaxial films of ε-Fe2O3 on GaN

ABSTRACT In the present paper we discuss correlations between crystal structure and magnetic properties of epitaxial ε-Fe2O3 films grown on GaN. The large magnetocrystalline anisotropy and room temperature multiferroic properties of this exotic iron oxide polymorph, make it a perspective material for the development of low power consumption magnetic media storage devices. Extending our recent progress in PLD growth of ε-Fe2O3 on the surface of technologically important nitride semiconductors, we apply reciprocal space tomography by electron and x-ray diffraction to investigate the break of crystallographic symmetry occurring at the oxide-nitride interface resulting in the appearance of anisotropic crystallographic disorder in the sub-100 nm ε-Fe2O3 films. The orthorhombic-on-hexagonal nucleation scenario is shown responsible for the development of a peculiar columnar structure observed in ε-Fe2O3 by means of HRTEM and AFM. The complementary information on the direct and reciprocal space structure of the columnar ε-Fe2O3 films is obtained by various techniques and correlated to their magnetic properties. The peculiar temperature dependence of magnetization studied by the small-field magnetization derivative method and by neutron diffraction reveals the existence of a magnetic softening below 150 K, similar to the one observed earlier solely in nanoparticles. The magnetization reversal in ε-Fe2O3 films probed by X-ray magnetic circular dichroism is found different from the behavior of the bulk averaged magnetization measured by conventional magnetometry. The presented results fill the gap between the numerous studies performed on randomly oriented ε-Fe2O3 nanoparticles and much less frequent investigations of epitaxial epsilon ferrite films with lattice orientation fixed by the substrate.
