9. Terahertz One-Port De-Embedding Method for Extracting Dielectric Constant of SiO2 in Standard CMOS

Abstract

This article presents a one-port de-embedding method for extracting dielectric constant of SiO2 in standard complementary metal-oxide-semiconductor (CMOS) at terahertz frequencies. Instead of extracting dielectric constant using absolute parameters from one cavity resonator, the presented method extracts key information from relative differences of three designated cavity resonators. By doing so, this method gains a unique de-embedding technique that can remove the effect of the feeding network and other repeatable errors, which simplifies the calibration and increases measurement accuracy. Furthermore, compared with conventional resonant methods requiring widely swept data or complex data processing, the proposed method only requires fL and QL, which can be directly measured even from a narrow frequency band. Therefore, it reduces the measurement requirement and lowers the detuned error. For validation, both simulations and experiments are carried out at 140, 300, and 450 GHz. The testing samples are fabricated using commercial 0.18-μm and 65-nm CMOS processes and measured by a terahertz on-wafer measurement setup. Results show full on-chip compatibility, greater simplicity, and good de-embedding effects, making this method suitable for on-chip dielectric characterizations.

Abstract

Aim: Angong Niuhuang pill (ANP) is a traditional Chinese medicine (TCM) drug widely used for treating stroke. This study aimed to investigate the effect of ANP on respiratory nursing outcomes in chronic obstructive pulmonary disease (COPD) patients following cardiac surgery. Methods: A total of 80 COPD patients following cardiac surgery were enrolled and randomized into the control group receiving routine postoperative nursing and ANP group additionally receiving ANP treatment for 3 days (n = 40 for both group). The frequency of back percussion, time of back percussion, amount of expectoration, arterial blood gas levels were compared between groups. Results: Compared to the control group, the ANP group had a significantly shorter daily mean time of back percussion at day 3 (p =.036) and day 7 (p =.014). The daily mean amount of expectoration was higher at day3 (p =.018) but lower at day 7 (p =.043) in the ANP group than in the control group. In addition, the ANP group had significantly higher hemoglobin saturation (SpO2) and partial pressure of oxygen (PaO2) but lower partial pressure of carbon dioxide (PaCO2) at both day 3 and day 7 than the control group (all p <.05). Furthermore, the time of postoperative aerosol inhalations (p =.041), pulmonary infection rate (p =.025) and postoperative hospital stay (p =.036) were significantly reduced in the ANP group. The ANP group had significantly lower TCM symptom scores at day 3 and day 7 after surgery. Conclusion: These results suggested that ANP treatment can effectively promote the postoperative recovery and respiratory nursing outcomes in COPD patients following cardiac surgery.

Abstract

Objective: To investigate the application of nursing-sensitive quality indicators in evaluating nursing efficacy., Materials and Methods: The study involved the 97 nursing units of four general hospitals, where quality-improvement projects were implemented. The efficacy of the projects was measured through the use of nursing-sensitive quality indicators followed by a Plan-Do-Study-Act cycle. Nursing efficacy was observed before and after the implementation., Results: Indicators revealed that patient satisfaction with basic nursing care, professional skills, and service attitude increased significantly after implementation of the quality-improvement projects (p<0.05). The incidence of nursing adverse events, including deficient care and accidents, also decreased significantly (p<0.01). However, patient satisfaction with the medical environment did not increase., Conclusions: Nursing-sensitive quality indicators are a valid and reliable way to determine if nursing quality-improvement projects are efficacious. They also promote continual improvement in nursing quality and provide a scientific evidence for setting implementation plan and detecting the implementation efficacy in nursing care, and possess certain promoting effects on the continual improvement of nursing quality.
