Abstract

Aims: To investigate the differences in disrupted rhythms between healthy people and patients with functional gastrointestinal disorders (FGIDs) and their associations with mood disorders during the coronavirus disease 2019 (COVID-19) pandemic. Methods: The rhythm scales were composed of subscales 1 and 2 for the assessment of life-work and entertainment rhythms, respectively; Zung's Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) were used to assess mood disorders. Results: A total of 671 patients with FGIDs and 4373 healthy people successfully participated. The scores of subscales 1 and 2 for patients with FGIDs were significantly higher than those for healthy people (p <.005). The SAS and SDS scores, their prevalence rates were significantly higher than those for the healthy group (all p <.001). Health status, current occupation, life-work rhythm, SDS, and SAS were independent related factors of FGIDs. The score of life-work-entertainment rhythm was significantly positively correlated with SDS and SAS (both p <.001). Conclusion: Disrupted rhythms in patients with FGIDs under the COVID-19 pandemic were more frequently and significantly positively associated with mood disorders. [ABSTRACT FROM AUTHOR]

Abstract

This thesis can be divided into four parts. In the first part of the work, the simplified model of the chip is presented. The multiple silicon-oxide layers and passivation layers are simplified. The simplified chip model can be simulated in common PC by the 3D EM simulator Ansys HFSS. Besides, the limitations by design rules of standard CMOS process are analyzed for on-chip dipole design work. After building up the simplified model, the on-chip dipole can be designed. In the second part of the work, the model of the on-chip dipole is studied. The formula of the radiation resistance is presented and amended with several key parameters. Then, the formulas of conductor resistance and surface wave resistance are presented. Next, the effect of silicon substrate and silicon-oxide layers is analyzed by employing the on-chip transmission line. The telegraph equation model of the on-chip transmission line is extracted by simulated S parameters. The multiple grids circuit is proposed for the model used in Agilent ADS, SPICE and so on. The mutual coupling between on-chip antenna and spiral inductor or coplanar waveguide is studied, tested and analyzed in the third part. Coupling mechanism is studied based on frequency and spacing between each other and equivalent circuits are presented. Also, coupling effects on on-chip antenna and spiral inductor or coplanar waveguide is discussed. Finally, a switchable balun is design for integration T/R switch with on-chip dipole. Transistor in CMOS is modeled in EM simulator HFSS and T/R switch with on-chip dipole is designed and optimized. Master of Engineering

Abstract

In this paper, the formula of radiation resistance of 60 GHz on-chip dipole is proposed. Three empirical factors involving the effects of passivation layer, lossy silicon substrate and the radiation of surface wave are extracted and expressed into close-form formulas. The accuracy error of the amended formula is less than 5%. [ABSTRACT FROM PUBLISHER]

Abstract

Background and Aim: Fexuprazan is a novel potassium-competitive acid blocker (P-CAB). This study aimed to explore the noninferior efficacy and safety of fexuprazan to esomeprazole in treating erosive esophagitis (EE)., Methods: This was a phase III, randomized, double-blind multicenter study. Patients with endoscopically confirmed EE were randomized to receive fexuprazan 40 mg or esomeprazole 40 mg once a daily for 4-8 weeks. The healing rates of EE, symptom response, GERD-health-related quality life (GERD-HRQL), and treatment-emergent adverse events (TEAEs) were compared between fexuprazan group and esomeprazole group., Results: A total of 332 subjects were included in full analysis set (FAS) and 311 in per-protocol set (PPS). The healing rates of fexuprazan and esomeprazole groups at 8 weeks were 88.5% (146/165) and 89.0% (145/163), respectively, in FAS and 97.3% (145/149) and 97.9% (143/146), respectively, in PPS. Noninferiority of fexuprazan compared with esomeprazole according to EE healing rates at 8 weeks was demonstrated in both FAS and PPS analysis. No significant difference was found between groups in EE healing rates at 4 weeks, symptom responses, and changes of GERD-HRQL. The incidence of drug-related AEs was 19.4% (32/165) in fexuprazan arm and 19.6% (32/163) in esomeprazole arm., Conclusion: This study demonstrated noninferior efficacy of fexuprazan to esomeprazole in treating EE. The incidence of TEAEs was similar between fexuprazan and esomeprazole.
