This article compares the diagnostic performance of two methods for evaluating adnexal masses for malignancy: IOTA's newer model for quantitative methodical assessment (ADNEX) and expert subjective assessment (SA). The study reviewed 17 articles and extracted results for 6,077 adnexal masses, which were confirmed by postoperative pathology. ADNEX demonstrated a sensitivity of 91.3% and a specificity of 84.1%, while SA had a sensitivity of 89.4% and a specificity of 96%. The study found that SA had significantly higher specificity compared to ADNEX, but there was no statistically significant difference in sensitivity between the two methods. The authors suggest that more research should be conducted to determine the superiority of ADNEX over subjective assessment in evaluating adnexal masses for malignancy via ultrasound.

This article compares the diagnostic performance of two methods, the IOTA Simple Rules (SR) and expert subjective assessment (SA), in evaluating adnexal masses for malignancy. The study analyzed 19 articles published between 2016 and 2024, which included a total of 6,012 adnexal masses. The results showed that SA had significantly higher sensitivity and specificity compared to SR assessment. These findings suggest that diagnostic criteria like simple rules may influence the subjective assessment of adnexal masses by physicians. Further research is needed to explore this phenomenon and its implications for clinical practice. [Extracted from the article]

This article compares the diagnostic performance of a quantitative methodical assessment called IOTA logistic regression 2 (LR2) and expert subjective assessment (SA) in evaluating the malignancy of known adnexal masses. The study analyzed 9 primary articles published between 2016 and 2024, which included a total of 2,602 adnexal masses. The results showed that SA had significantly higher sensitivity and specificity compared to LR2. The authors suggest that further research should be conducted to determine if physicians subconsciously use diagnostic criteria like LR2 when subjectively assessing adnexal masses via ultrasound.

This article compares the performance of two ultrasound models, the ADNEX test and the Simple Rules (SR) test, in differentiating between benign and malignant adnexal masses. The meta-analysis included 26 articles and a total of 9,058 adnexal masses. The results showed that ADNEX had a sensitivity of 91.3% and a specificity of 84.1%, while SR had a sensitivity of 86.3% and a specificity of 90.5%. The study concluded that clinicians should consider these differences when choosing the most appropriate approach for diagnosing and managing adnexal masses. [Extracted from the article]

A meta-analysis compared the performance of two quantitative ultrasound models, IOTA ADNEX and logistic regression 2 (LR2), in differentiating between benign and malignant adnexal masses. The study found that ADNEX had a higher sensitivity (91.3%) compared to LR2 (84%) in correctly identifying malignancy. However, there was no statistically significant difference in specificity between the two models. The findings suggest that ADNEX may be superior to LR2 as an ultrasound criterion for assessing adnexal masses, but further research is needed to determine if ADNEX should replace LR2 as the gold standard criterion.

This article compares the performance of two ultrasound models, IOTA logistic regression 2 (LR2) and simple rules (SR), in differentiating between benign and malignant adnexal masses. The study used a meta-analysis of primary articles published between 2016 and 2024 to compare the sensitivities and specificities of the two models. The results showed that SR had a higher sensitivity and superior specificity compared to LR2. The authors suggest that more research should be conducted to support the hypothesis that SR should be preferred over LR2 for adnexal mass sonography. [Extracted from the article]

The total ionizing dose effect on a commercial Flash-based field programmable gate array is investigated by gamma ray radiation. The floating-gate threshold and logic propagation delay are measured with respect to the total dose. A physical model is also developed to express the threshold in terms of total dose for both unbiased- and biased-radiation conditions. Experimental data of the threshold fit this model for extracting the modeling parameters. The modeling predictions match further experimental data very well for low to moderate total dose. Using modeling and SPICE simulation together, the prediction of the propagation delay is compared to the experimental data. The biased condition has a good fit while the unbiased prediction over-degrades the propagation delay with respect to the experimental data. [ABSTRACT FROM AUTHOR]

The single event effects and hardening of a 0.15 μm antifuse FPGA, the AX device, were investigated by beam test and computer simulation. The beam test showed no permanent damage mode. Functional failures were observed and attributed to the upsets In a control logic circuit, the startup sequencer Clock upsets were observed and attributed to the single event transients in the clock network. Upsets were also measured In the user flip-flop and embedded SRAM. The hardening technique dealing with each upset mode is discussed in detail. SPICE and three-dimensional mixed-mode simulations were used to determine the design rules for mitigating the multiple upsets due to glancing angle and charge sharing. The hardening techniques have been implemented in the newly fabricated RTAXS device. Preliminary heavy-ion-beam test data show that all the hard-wired hardening solutions are working successfully.
