Abstract

Introduction: Neoadjuvant immunotherapy plus chemotherapy has ushered in a new era for surgical treatment for patients with NSCLC. This study aimed to examine the efficacy and safety of neoadjuvant immunotherapy plus chemotherapy in NSCLC. Methods: Eligible studies were identified from PubMed, Embase, Web of Science, Cochrane Library, ClinicalTrials.gov, and conference meeting abstracts. The endpoints included major pathological response (MPR), complete pathological response (pCR), surgical resection rate, R0 resection, treatment‐related adverse events (TRAEs), severe adverse events (SAEs), surgical complications, treatment discontinuation, surgical delay, and treatment‐related death. Stata 18 software was used for statistical analysis, and p < 0.05 was considered statistically significant. Twenty‐two studies including a total of 1108 patients were eligible for this study. Results: Among the patients who received neoadjuvant immunotherapy plus chemotherapy, the pooled MPR rate was 51% (95% CI [0.44–0.58]), and pCR rate was 34% (95% CI [0.28–0.40]). The pooled surgical resection rate was 85% (95% CI [0.81–0.89]), and the pooled R0 rate was 94% (95% CI [0.91–0.96]). The pooled rate of pathological tumor downstaging was 84% (95% CI [0.79–0.88]), and the pooled rate of pathological nodal downstaging was 38% (95% CI [0.23–0.57]). During the treatment of neoadjuvant immunotherapy plus chemotherapy with or without surgery, the pooled rate of TRAEs (any grade) was 84% (95% CI [0.73–0.91]), and the pooled rate of SAEs was 29% (95% CI [0.21–0.38]). Surgical complications pooled rate was 25% (95% CI [0.14–0.41]). The pooled rate of treatment discontinuation (11%, 95% CI [0.09–0.13]), surgical delay (3%, 95% CI [0.02–0.05]), and treatment‐related death (2%, 95% CI [0.02–0.03]) were conducted. Conclusion: Neoadjuvant immunotherapy plus chemotherapy provides a high pathological response, surgical resection rate, R0 resection rate, and pathological downstage rate and has a low risk of increasing the incidence of SAEs, surgical complications, treatment discontinuation, surgical delay, and treatment‐related death. The validation of prospective and large sample studies is needed to confirm this conclusion. [ABSTRACT FROM AUTHOR]

Abstract

Non-thermal plasma discharges, particularly dielectric barrier discharges (DBDs), are the most common method of ozone generation. The aim of this research was to optimize the micro-discharges in DBDs, to improve ozone generation efficiency. The electrical characteristics of DBDs were researched, and the effects of the physical and electrical parameters of DBDs on ozone generation were investigated. Four DBD based ozone reactors, including plate configuration and cylindrical configuration, were designed and developed. Three major energization modes, including transient (40 ms) AC power supply, continuous AC power supply and pulsed power supply, were used for the investigation of ozone generation performance. Under transient AC energisation in oxygen, it was found that the ozone generation efficiency at 2 bar absolute was 217 g/kWh, increased by 31% compared with that at 1 bar absolute. The ozone generation efficiency was found to increase with decreasing E/N in the range from 126 Td to 185 Td. Under continuous AC energisation, the ozone concentration was found to increase as the gas flow rate decreased (from 1 L/min to 0.4 L/min) or applied voltage was increased (from 3.5 kV to 6 kV). Under optimized conditions, the highest ozone concentration obtained was 271 g/Nm3, which is promising in comparison with previously-published data. The ozone generation efficiency was found to reduce as the ozone concentration increased above 30 g/Nm3. Furthermore, it was found that the AC energization frequency had no obvious effect on the behaviour of micro-discharges, or on the ozone generation efficiency. Pulsed DBDs for ozone generation was found to be less efficient than continuous AC energisation, for the conditions investigated herein. This research has achieved the desired combination of high ozone generation efficiency at high ozone concentration (>150 g/Nm3), based on DBDs The curve of ozone generation efficiency versus ozone concentration achieved shows more efficient performance than that in the literature: at the typical industrial ozone concentration of 150 g/Nm3 for waste water treatment, the ozone generation efficiency in this work was ~8.2 kWh/kg, ~20% higher than that in the literature.

Abstract

The Lanzhou Heavy Ion Research Facility (LIRF) is the largest heavy ion research facility in China, providing a substantial volume of experimental data for fundamental research in nuclear physics. The Topmetal-CEE is a pixel readout chip specifically designed for tracking detectors. Within the Topmetal-CEE framework, the front-end amplifier and comparator necessitate precisely adjustable bias voltages. Hence, in this paper, a 14-bit resolution DAC with an R-2R resistor network structure is designed, along with an amplifier featuring high driving capabilities as the DAC driver, thus preventing potential impedance issues when driving large pixel arrays. Test results demonstrate that the DAC module, operating under a 3.3 V supply voltage, can consistently output voltages ranging from 0 to 1.8 V. Furthermore, the differential non-linearity error is less than 1.07 LSB, and the integral non-linearity error is less than 1.57 LSB. [ABSTRACT FROM AUTHOR]

Abstract

To overcome the shortcoming wherein the accuracy of subsea cable detection can be affected by the determination of the bias vector, scale factors, and non-orthogonality corrections of the vector magnetometer, a real-time attitude-independent route tracking method for subsea power cables is investigated theoretically and experimentally by means of scalar magnetic field checking. The measurement of the magnetic field Bc produced by the current in a cable is made immune to the influence of the platform attitude by extracting the component of Bc along the geomagnetic field using a high-bandwidth self-oscillating optically pumped magnetometer. The self-oscillating frequency is proved to be independent of the attitude of the magnetometer with the theoretical model. Experiments are carried out to test the attitude-independent performance, and the effectiveness of route tracking is verified by the results of the sea experiment. The proposed method will effectively improve the ability to locate subsea cables under high sea conditions. [ABSTRACT FROM AUTHOR]
