Performance of Fitness Functions Based on Natural Frequencies in Defect Detection Using the Standard PSO-FEM Approach

Structural defect detection based on finite element model (FEM) updating is an optimization problem by minimizing the discrepancy of responses between model and measurement. Researchers have introduced many methods to perform the FEM updating for defect detection of the structures. A popular approach is to adopt the particle swarm optimization (PSO) algorithm. In this process, the fitness function is a critical factor in the success of the PSO-FEM approach. Our objective is to compare the performances of four fitness functions based on natural frequencies using the standard PSO-FEM approach for defect detection. In this paper, the definition of the standard PSO algorithm is first presented. After constructing the finite element benchmark model of the beam structure, four commonly used fitness functions based on natural frequencies are outlined. Their performance in defect detection of beam structures will be evaluated using the standard PSO-FEM approach. Finally, in the numerical simulations, the population diversity, success rate, mean iterations, and CPU time of the four fitness functions for the algorithm are calculated. The simulation results comprehensively evaluate their performances for single defect and multidefect scenario, and the effectiveness and superiority of the fitness function S 4 will be demonstrated.
At the intersection of homophobia and racism: Sociocultural context and the sexual health of South Asian Canadian gay and bisexual men.

Objectives: South Asian gay and bisexual men in Canada are at risk for experiencing both intersectional structural oppressions related to homophobia and racism as well as for the acquisition of sexually transmitted infections including HIV. Our objective was to examine intersectional stigma among South Asian gay and bisexual men and its effects on their mental and sexual health.Design: We recruited 39 South Asian gay and bisexual men in the Greater Toronto Area and interviewed them via focus groups (n = 37) or one-on-one interviews (n = 2). The facilitators used a semi-structured interview protocol covering topics about sexual health of South Asian gay and bisexual men, including their how their home backgrounds and their experiences of being South Asian in predominantly white gay spaces affected their sexual health, and how these experiences shaped their attitudes about sexual health services. Data were analysed to understand how Intersectional stigma affected perceived choices and health among South Asian GBM.Results: Participants reported significant concerns about the effects of intersectional oppressions as South Asian gay and bisexual men, including distress about the potential social harms arising to one’s family for having a gay or bisexual son. Men also described feeling excluded by the white-dominated gay community. Intersectional stigma led to loneliness and social isolation among South Asian gay and bisexual men, and limited social power in sexual relationships.Conclusions: Findings suggest that South Asian gay and bisexual men preferred programs that focused on reducing social isolation and loneliness, as opposed to traditional safer sex programming focusing on HIV risk education.

Study of Nanowire-Based Integrated via Technology for CMOS Application in Millimeter-Wave Frequencies

This work shows a novel integrated via structure based on 1.2-<inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> thick copper nanowires (NWs) for use in CMOS applications at millimeter-wave frequencies. Coplanar waveguide (CPW) lines are fabricated on a 5000-<inline-formula> <tex-math notation="LaTeX">$\Omega $ </tex-math></inline-formula>-cm high-resistivity silicon wafer and connected by NW vias that are grown in integrated anodized alumina oxide (AAO). The AAO layer is fabricated by anodizing an evaporated aluminum layer onto the silicon wafer. This cointegrated technology has 0.095-dB insertion loss for 0.3-mm long circuits with two vias at 40 GHz. The results are promising with an estimated loss per via of approximately 0.0275 dB. The fabricated structure shows great performance agreement with its reference test circuits of similar length. The design comparisons of circuits with different via dimensions and positions show that the shorter the via length, the wider the via width; and placing the via on the CPW ground plane closer to the signal line provides better performance.

Engineered Continental‐Scale Rivers Can Drive Changes in the Carbon Cycle

Floodplains of large alluvial rivers modulate the composition of riverine organic carbon (OC) and control OC oxidative loss, constituting a critical component in the global river‐atmosphere‐ocean carbon cycle. Therefore, anthropogenic management disconnecting rivers from their floodplains is expected to reduce the oxidative loss and to change the quality and quantity of riverine OC exported to the ocean. Here, we test this idea by combining two chronometers—14C age spectra of OC and optically stimulated luminescence ages of quartz—to interrogate sediments of the Lower Mississippi River (LMR) system to constrain the anthropogenic effects on carbon cycling in a continental‐scale sediment routing system. The 14C age of the LMR OC has been reduced from >5,000 yr in prehistoric sediments to <3,000 yr in historic and modern sediments with significantly narrowed age spectrum width, following centuries of embanking the LMR. Bank stabilization reduced the river‐floodplain sediment exchange by ∼90%, effectively cutting off older floodplain OC from the river and reducing OC residence time in the severely truncated floodplain system, and expedited the downstream transmission of OC. The reduced residence time will have decreased riverine OC loss and enhanced younger OC delivery to marine sediments. We estimate that the oxidative loss of the LMR OC has been reduced by ≥ 1.1 Tg C/yr or 40%. Extrapolation to other large rivers that have undergone anthropogenic changes similar to the LMR illustrates that this process likely represents a carbon sink that can significantly increase if currently free‐flowing large tropical rivers are embanked in the future.

Influence of amino acid side chains on the formation of two component self-assembling nanofibrous hydrogels

Herein, we report the synthesis and optimization of an aqueous phase two-component co-assembled nanofibrous hydrogel based on charge-transfer (CT) between pyrenebutyric acid and naphthalene diimide-capped groups. This donor–acceptor CT interaction is a powerful driving force that can induce self-assembly in the aqueous phase even if the molecule contains only a single amino acid. The intermolecular CT interactions for mixed components can also be visualized in the quantum-chemical approach. This two-component supramolecular co-assembly provides a new path for the design of self-assembled nanomaterials.
Research on Residents’ Willingness to Pay for Promoting the Green Development of Resource-Based Cities: A Case Study in Chifeng

Resource-based cities have made significant contributions to the development of human beings but have also accumulated various unsustainable ills. For this reason, China put forward the strategy of green development. This study used questionnaires to explore the extent of residents’ understanding of regional green development in Chifeng City and their willingness to support local green development, and further analyzed the differences in the residents’ attitudes and willingness to pay (WTP) with different socioeconomic characteristics. The results showed that most of the respondents supported the green development strategy and demonstrated a strong willingness to participate in regional green development investment. According to calculations, the per capita WTP for green development in Chifeng is 45.05 yuan/a (about 7 dollars/a, 5.7 euros/a). Urban residents, government employees, and well-educated respondents were more inclined to support regional green development and showed a greater WTP. Elderly and female respondents agreed more with the government’s green development promotion, while the young and middle-aged populations and men tended to have higher green development expenditures. The respondents’ annual income difference was reflected in the amounts of residents’ WTP. This study also offered scientific support and policy assistance to promote the environmental protection work from government-led to public participation.
Synthesis, Spectroscopic Characterization, and Biological Activities of New Binuclear Co(II), Ni(II), Cu(II), and Zn(II) Diimine Complexes

Metal-ligand complexes have attracted major interest due to their potential medical applications as anticancer agents. The work described in the current article aimed to synthesize, spectroscopic, thermal, and biological studies of some metal-diimine complexes. A diimine ligand, namely 2-{[2-(4-chlorophenyl)-2-hydroxyvinyl]-hydrazonomethyl}phenol (diim) was prepared via the reaction of p-chlorophenacyl bromide with hydrazine hydrate in ethanol, then condensation was completed with 2-hydroxybenzaldehyde in acetic acid. The Co(II), Ni(II), Cu(II), and Zn(II) complexes were prepared with a metal:ligand stoichiometric ratio of (2:1). 1H-NMR, UV-Vis, FTIR spectroscopic data, molar conductivity measurements, and microanalytical data (carbon, hydrogen, nitrogen, and halogen) were used for characterization of the formed ligand and its metal complexes. It was found that the diimine ligand act as tetradentate fashion. The non-electrolytic character for all the complexes was proved by molar conductivity. The first metal atom of the synthesized binuclear diimine complexes coordinates with the nitrogen of hydrazine group and oxygen of OH group. While, the second metal atom coordinates with the other nitrogen atom of the hydrazine group and oxygen of phenolic group. All the synthesized metal complexes have a six-coordinated except for Zn(II) has four-coordinated. Thermogravimetric analysis and its differential analysis were done to discuss the thermal degradation of the free ligand and its metal complexes. Molecular docking calculation showed that the diimine ligand is a good inhibitor for breast cancer 3hb5 and 4o1v kidney cancer proteins. Additionally, these compounds were evaluated as antibacterial and antifungal agents.
Active damping method for voltage source inverter-based distributed generator using multivariable finite-control-set model predictive control

Despite its advantages, the LCL filter can significantly distort the grid current and constitute a substantially more complex control issue for the grid-connected distributed generators (DGs). This paper presents an active damping approach to deal with the LCL filter's oscillation for the finite-control-set model predictive control (FCS-MPC)-three-phase voltage source inverters (VSIs)-based DG. The new approaches use the multivariable control of the inverter side's filter current and capacitor voltage to suppress the LCL filter resonance. The proposed method has been tested in steady-state and under grid voltage disturbances. The comparative study was also conducted with the existing virtual resistance active damping approaches for an FCS-MPC algorithm. The study validates the developed control schemes' superior performance and shows its ability to eliminate lower-order grid current harmonics and decrease sensitivity to grid voltage distortion.
Monotone iterative technique for time-space fractional diffusion equations involving delay

Abstract. This paper considers the initial boundary value problem for the time-space fractional delayed diffusion equation with fractional Laplacian. By using the semigroup theory of operators and the monotone iterative technique, the existence and uniqueness of mild solutions for the abstract time-space evolution equation with delay under some quasimonotone conditions are obtained. Finally, the abstract results are applied to the time-space fractional delayed diffusion equation with fractional Laplacian operator, which improve and generalize the recent results of this issue.
“I’m not Just a Babysitter”: Masculinity and Men’s Experiences of First-Time Fatherhood

A man’s transition into the role of a father is a rewarding yet challenging experience for many men. This study explores how men navigate contradictory roles of fatherhood and the impact this has on their identities. Fifteen first-time fathers were interviewed, and their responses were analysed using thematic and discourse analysis tools. Findings revealed that fathers both adhered to and challenge masculine ideals of fatherhood. Men described both traditional and non-traditional roles in their becoming a father, being a father, and navigating fatherhood and manhood. The continuation and contestation of masculine discourses in the experiences of fatherhood was found to influence their involvement with raising children and employment, as well as their relationships. Overall, these findings highlight the uncertainty that shapes modern fathers’ roles and demonstrates how fathers move between both traditional and new fatherhood roles.
Image Reversal Resist Photolithography of Silicon-Based Platinum and Silver Microelectrode Pattern

Silicon-based platinum (Pt) and silver (Ag) microelectrodes are constructed using photolithography technique and used in detecting arsenic activity in different electrolytes. Pt and Ag have good properties either as a working, a counter, or a reference electrode due to their low electrical resistance, high melting point, and high chemical stability. This chemical sensor has the ability to detect the changes in the level or activity of arsenic in electrolytes. Patterning these metals by wet chemical or dry etching is not a feasible process as these metals cannot be etched properly. The lift-off process can be applied to ease the etching process, but it has a major problem whereby the metal particles or ears may remain at the edges at the end of the process. The process variables, particularly the resist slope, were investigated to reduce possible defects using an image reversal resist. The thickness and angle of the resist side wall were measured by SEM. The effects of many factors that may influence or resist steep angle formation were analyzed and optimized with the Design of Experiment (DOE) technique to achieve the target recipe of resist angle < 60°. The lower angle of the resist side wall resulted in a better percentage yield of good electrode pattern after the lift-off process. The ability of fabricated microelectrode and influence of supporting electrolytes in arsenic determination were discussed.
