    Full text link
    We propose a flat nonlinear placement algorithm FFTPL using fast Fourier transform for density equalization. The placement instance is modeled as an electrostatic system with the analogy of density cost to the potential energy. A well-defined Poisson's equation is proposed for gradient and cost computation. Our placer outperforms state-of-the-art placers with better solution quality and efficiency

    This cross-sectional study investigates the impact of the Commodity Supplemental Food Program (CSFP) Nutrition Education With Seniors (NEWS) program on the food-related challenges faced by older adults. The study used quarterly evaluations spanning 2012 to 2022, focusing on the application of newsletter information; 3,281 surveys were completed. Descriptive statistics and chi-square tests were employed for sociodemographic analysis, while z-tests with Bonferroni correction compared column proportions. Respondents were primarily female (64.5%), aged 60-69 (52.1%). Many encountered a decreased food supply (47.1%), yet experienced no impacts from these changes (47.3%.) Most used NEWS information for food choices (79.7%) and resource management (83.9%), with 65.6% preparing NEWS recipes. Gender and age significantly affected NEWS information use (p\u3c0.02), while changing food supply impacted food choices (p=0.046). Notably, those receiving additional needed food applied NEWS for choices more than those with excess supply (p\u3c0.05). Participants receiving more than needed food demonstrated higher use of resource management tips (p\u3c0.05). These findings underscore the NEWS program’s positive impact on older adults, influencing informed food choices, effective resource management, and the preparation of healthy recipes using CSFP commodities. Furthermore, gender, age, and food supply changes modify the application of NEWS information, highlighting the program’s adaptability to diverse circumstances

    Aim To examine the relationship between borderline personality symptoms and Internet addiction as well as the mediating role of mental health problems between them. Methods A total of 500 college students from Taiwan were recruited and assessed for symptoms of Internet addiction using the Chen Internet Addiction Scale, borderline personality symptoms using the Taiwanese version of the Borderline Symptom List and mental health problems using four subscales from the Symptom Checklist-90-Revised Scale (interpersonal sensitivity, depression, anxiety, and hostility). Structural equation modeling (SEM) was used to test our hypothesis that borderline personality symptoms are associated with the severity of Internet addiction directly and also through the mediation of mental health problems. Results SEM analysis revealed that all paths in the hypothesized model were significant, indicating that borderline personality symptoms were directly related to the severity of Internet addiction as well as indirectly related to the severity of Internet addiction by increasing the severity of mental health problems. Conclusion Borderline personality symptoms and mental health problems should be taken into consideration when designing intervention programs for Internet addiction

    Structural symmetry-breaking plays a crucial role in determining the electronic band structures of two-dimensional materials. Tremendous efforts have been devoted to breaking the in-plane symmetry of graphene with electric fields on AB-stacked bilayers or stacked van der Waals heterostructures. In contrast, transition metal dichalcogenide monolayers are semiconductors with intrinsic in-plane asymmetry, leading to direct electronic bandgaps, distinctive optical properties and great potential in optoelectronics. Apart from their in-plane inversion asymmetry, an additional degree of freedom allowing spin manipulation can be induced by breaking the out-of-plane mirror symmetry with external electric fields or, as theoretically proposed, with an asymmetric out-of-plane structural configuration. Here, we report a synthetic strategy to grow Janus monolayers of transition metal dichalcogenides breaking the out-of-plane structural symmetry. In particular, based on a MoS2 monolayer, we fully replace the top-layer S with Se atoms. We confirm the Janus structure of MoSSe directly by means of scanning transmission electron microscopy and energy-dependent X-ray photoelectron spectroscopy, and prove the existence of vertical dipoles by second harmonic generation and piezoresponse force microscopy measurements

    Prostatic Relaxation Induced by Loperamide Is Reduced in Spontaneously Hypertensive Rats

    This paper shows a new finding about the decrease of relaxative response to loperamide in prostate of spontaneously hypertensive rats (SHR) as compare to normal rats (WKY). Authors demonstrated the reduction of ATP-sensitive potassium channels is resposible for this change using immunoblotting analysis and the decrease of action induced by diazoxide. This view is not mentioned before and is the first one reporting this result
