Update Package_Height_Max from Orcad Capture

I am using OrCAD PCB Designer Standard version 17.4-2019. I want to force update the Package_Height_Max property on the place bound top shape. The footprint library that we've created has that property set in the dra file, but I'd like to override that from capture so I can be certain that the height is correct.

This is coming from a place where we have created a very large footprint library over that past ++ years. Everyone who creates a new footprint is supposed to make sure that we add Package_Height_Max to the footprint, but of course footprints get reused for various parts, not all of which will have the same package height. What I want to do is export a list of package heights from our part database and then import the package heights into Capture and override the package height in the footprint.

I have found a post here  Using Height Property from Orcad Capture which says its not possible, but it also says its from 15 years ago, so maybe things have changed?

Socionext Accelerates SoC Design Breakthroughs with Cadence Signoff Tools

Socionext, a leader in SoC design, recently made significant strides in enhancing its design efficiency for a complex billion-gate project. Faced with the initial challenges of lengthy eight-day iterations and a protracted two-month timing signoff process, the objective was to reduce the iteration cycle to just three days. By integrating Cadence's cutting-edge solutions—Certus Closure Solution, Tempus Timing Solution, and Quantus Extraction Solution—Socionext achieved remarkable improvements.

Notably, the Tempus DSTA tool dramatically cut timing closure time by 73%, outperforming conventional single-machine STA methods. This achievement, combined with the synergistic use of Cadence's Certus Closure and Tempus Timing solutions, allowed Socionext to meet their ambitious three-day iteration target and double productivity. Additionally, integrating these solutions significantly decreased both human and machine resource needs, slashing memory and disk costs by up to 90% and halving engineering resources during the optimization and signoff phases.

For more on this collaboration, check out the "Designed with Cadence" success story video on Cadence's website and YouTube channel.

The Best Way to Learn – Cadence Cerebrus AI-Driven Design Implementation

The Cadence Cerebrus Intelligent Chip Explorer is a revolutionary, machine learning-driven, automated approach to chip design flow optimization. Block engineers specify the design goals, and Cadence Cerebrus will intelligently optimize the Cadence digital full flow to meet the power, performance, and area (PPA) goals in a completely automated way. Use Cerebrus Apps to optimize some aspects of the design as well.

Running a full RTL to GDSII flow, Cadence Cerebrus has a lot of possibilities and combinations of different tool settings to explore.

Using the knowledge from previous runs, combined with on-the-fly analysis within the flow, Cadence Cerebrus can assess many settings combinations and fine-tune the flow accordingly in a very efficient manner.

As technology advances, projects become bigger and way more complex than before. The ability of a single engineer to run simultaneously a large number of blocks in a traditional way is limited. Cadence Cerebrus allows a single engineer to work more efficiently and implement more blocks, while maintaining the same or even better PPA, using compute power.

Being such a revolutionary tool, integrating Cerebrus into your existing flow is surprisingly simple as it can wrap around any existing flow scripts.

Please join me in this course, to learn about the features and basics of Cadence Cerebrus Intelligent Chip Explorer.

We’ll walk through the tool setting stage, explain what is a primitive and how it effects our run, talk about the cost function and the run goals.

We’ll understand the concept of scenarios, learn how to analyze the results of the different runs, and compare them.

In addition, we’ll talk about basic debug rules and methods to analyze failures.

Accuracy of CAD4TB (Computer-Aided Detection for Tuberculosis) on paediatric chest radiographs

Background

Computer-aided detection (CAD) systems hold promise for improving tuberculosis (TB) detection on digital chest radiographs. However, data on their performance in exclusively paediatric populations are scarce.

Methods

We conducted a retrospective diagnostic accuracy study evaluating the performance of CAD4TBv7 (Computer-Aided Detection for Tuberculosis version 7) using digital chest radiographs from well-characterised cohorts of Gambian children aged <15 years with presumed pulmonary TB. The children were consecutively recruited between 2012 and 2022. We measured CAD4TBv7 performance against a microbiological reference standard (MRS) of confirmed TB, and also performed Bayesian latent class analysis (LCA) to address the inherent limitations of the MRS in children. Diagnostic performance was assessed using the area under the receiver operating characteristic curve (AUROC) and point estimates of sensitivity and specificity.

Results

A total of 724 children were included in the analysis, with confirmed TB in 58 (8%), unconfirmed TB in 145 (20%) and unlikely TB in 521 (72%). Using the MRS, CAD4TBv7 showed an AUROC of 0.70 (95% CI 0.60–0.79), and demonstrated sensitivity and specificity of 19.0% (95% CI 11–31%) and 99.0% (95% CI 98.0–100.0%), respectively. Applying Bayesian LCA with the assumption of conditional independence between tests, sensitivity and specificity estimates for CAD4TBv7 were 42.7% (95% CrI 29.2–57.5%) and 97.9% (95% CrI 96.6–98.8%), respectively. When allowing for conditional dependence between culture and Xpert assay, CAD4TBv7 demonstrated a sensitivity of 50.3% (95% CrI 32.9–70.0%) and specificity of 98.0% (95% CrI 96.7–98.9%).

Conclusion

Although CAD4TBv7 demonstrated high specificity, its suboptimal sensitivity underscores the crucial need for optimisation of CAD4TBv7 for detecting TB in children.

Academic Neuroradiology: 2023 Update on Turnaround Time, Financial Recruitment, and Retention Strategies [CLINICAL PRACTICE]

SUMMARY:

The ASNR Neuroradiology Division Chief Working Group's 2023 survey, with responses from 62 division chiefs, provides insights into turnaround times, faculty recruitment, moonlighting opportunities, and academic funds. In emergency cases, 61% aim for a turnaround time of less than 45–60 minutes, with two-thirds meeting this expectation more than 75% of the time. For inpatient CT and MR imaging scans, 54% achieve a turnaround time of 4–8 hours, with three-quarters meeting this expectation at least 50% of the time. Outpatient scans have an expected turnaround time of 24–48 hours, which is met in 50% of cases. Faculty recruitment strategies included 35% offering sign-on bonuses, with a median of $30,000. Additionally, 23% provided bonuses to fellows during fellowship to retain them in the practice upon completion of their fellowship. Internal moonlighting opportunities for faculty were offered by 70% of divisions, with a median pay of $250 per hour. The median annual academic fund for a full-time neuroradiology faculty member was $6000, typically excluding license fees but including American College of Radiology and American Board of Radiology membership, leaving $4000 for professional expenses. This survey calls for further dialogue on adapting and innovating academic institutions to meet evolving needs in neuroradiology.

Analysis of Sleep and Circadian Rhythms from Drosophila Activity-Monitoring Data Using SCAMP

Sleep is a fundamental feature of life for virtually all multicellular animals, but many questions remain about how sleep is regulated and what biological functions it plays. Substantial headway has been made in the study of both circadian rhythms and sleep in the fruit fly Drosophila melanogaster, much of it through studies of individual fly activity using beam break counts from Drosophila activity monitors (DAMs). The number of laboratories worldwide studying sleep in Drosophila has grown from only a few 20 years ago to hundreds today. The utility of these studies is limited by the quality of the metrics that can be extracted from the data. Many software options exist to help analyze DAM data; however, these are often expensive or have significant limitations. Therefore, we describe here a method for analyzing DAM-based data using the sleep and circadian analysis MATLAB program (SCAMP). This user-friendly software has an advantage of combining several analyses of both sleep and circadian rhythms in one package and produces graphical outputs as well as spreadsheets of the outputs for further statistical analysis. The version of SCAMP described here is also the first published software package that can analyze data from multibeam DAM5Ms, enabling determination of positional preference over time.

Neural Stimulation during Drosophila Activity Monitor (DAM)-Based Studies of Sleep and Circadian Rhythms in Drosophila melanogaster

Sleep is a fundamental feature of life for virtually all multicellular animals, but many questions remain about how sleep is regulated by circadian rhythms, homeostatic sleep drive that builds up with wakefulness, and modifying factors such as hunger or social interactions, as well as about the biological functions of sleep. Substantial headway has been made in the study of both circadian rhythms and sleep in the fruit fly Drosophila melanogaster, much of it through studies of individual fly activity using Drosophila activity monitors (DAMs). Here, we describe approaches for the activation of specific neurons of interest using optogenetics (involving genetic modifications that allow for light-based neuronal activation) and thermogenetics (involving genetic modifications that allow for temperature-based neuronal activation) so that researchers can evaluate the roles of those neurons in controlling rest and activity behavior. In this protocol, we describe how to set up a rig for simultaneous optogenetic or thermogenetic stimulation and activity monitoring for analysis of sleep and circadian rhythms in Drosophila, how to raise appropriate flies, and how to perform the experiment. This protocol will allow researchers to assess the causative role in the regulation of sleep and activity rhythms of any genetically tractable subset of cells.
