This article reports the first operation of a double-sided CMOS pixelated ladder in a collider experiment, namely in the inner tracker volume of the Belle II experiment during the Phase 2 run of the SuperKEKB collider. Design and integration of the detector system in the experiment interaction region is first described. The two modules operated almost continuously during slightly more than four months, recording data for the monitoring of the hit rate close to beams. Details of the off-line data analysis are provided and a method to estimate particle momentum from the 2 hits measured per crossing particle is proposed.

Maintaining an adequate security level in computer infrastructures, like Internet-facing web servers, requires periodic assessment of their vulnerabilities with specialized security tools. nmap is arguably the most popular one, due to its versatility, powerful features, and low resource usage. However, this versatility can turn its usage difficult and error-prone, as it implements a lot of features and reports errors at runtime. This can lead to suboptimal results while designing auditing tasks. This research aims to decrease this complexity by developing a web GUI that favors experimentation, on-demand scans, and provides solutions to several shortcomings detected in the official one. We complemented it with a Domain Specific Language that implements early detection and reporting of syntax, type, and semantic errors when creating audit tasks. Both expand nmap possibilities, creating robust, schedulable, distributable, and portable auditing tasks able to find anomalies analyzing their output. Our initial release shows that the web GUI has been well received by several security related media and professionals. The language can detect and report a wide range of potential errors, substantially increasing the robustness of the created tasks. Therefore,
