Abstract: Techniques for code modification for automation detection are described. Web code is obtained corresponding to content to be served to a first client device in response to a first request from the first client device. Instances of a particular programmatic element in the web code are identified. In response to the first request, modified web code is generated from the web code by consistently changing the particular programmatic element to a modified programmatic element throughout the web code. The modified web code is caused to be provided to the first client device in response to the first request from the first client device. A communication is received from the first client device that is made in response to the modified web code. The communication includes an attempt to interact with the particular programmatic element that exists in the web code but not in the modified web code.

Abstract: A method of reducing the x-ray dose of a patient in an x-ray system includes defining a region of interest of the patient, obtaining at least two tracking images of a tracking element taken with at least one camera having a known positional relationship relative to an x-ray source and/or sensor, determining any movement of the tracking element between the acquisition of at least two tracking images, adjusting the collimator of the x-ray source to compensate for any movement of the tracking element between the acquisition of the at least two tracking images, providing that the field of exposure of the x-ray source is confined to the region of interest and obtaining at least one x-ray image of the region of interest after the adjustment of the collimator.

Abstract: An API call filtering system filters responses to API call requests received, via a network, from UEs. The API call filtering system is configured to require personalized API call requests wherein each API call (except for some minor exceptions) includes a unique UE identifier (“UEIN”) of the UE making the request. Using the UEIN, the web service or other service protected by the API call filtering system can be secured against excessive request iterations from a set of rogue UEs while allowing for ordinary volumes of requests of requests the UEs, wherein one or more boundaries between what is deemed to be an ordinary volume of requests and what is deemed to be excessive request iterations are determined by predetermined criteria.

Abstract: Techniques are provided for evaluating and modifying countermeasures based on aggregate transaction status. A first expression pattern is determined that occurs in each of first response messages served by the web server system in response to successful transactions of the transaction type. A second expression pattern is determined that occurs in each of second response messages served by the web server system in response to non-successful transactions of the transaction type requested. Aa status is determined for each of a plurality of transactions of the transaction type based on matching the first expression pattern or the second expression pattern to response messages served by the web server system. Aggregate status information for the transaction type based on the status for the set of operations is updated. Based on a change in the aggregate status information, a set of one or more security countermeasures is updated.

Abstract: An embodiment includes a process for treating an abdominal aortic aneurysm (AAA) endoleak with a shape memory polymer (SMP) foam device. First, a bifurcated stent graft is placed within the aneurysm while a micro guidewire is positioned within the aneurysm for future catheter access. Second, after placing the iliac graft extension, a catheter is introduced over wire to deliver embolic foams. Third, embolic foams expand and conform to the aneurysm wall. Fourth, embolic foams create a stable thrombus to prevent endoleak formation by isolating peripheral vessels from the aneurysm volume.
