Abstract: Devices, systems, and methods for planning radiosurgical treatments for neuromodulating a portion of the renovascular system may be used to plan radiosurgical neuromodulation treatments for conditions or disease associated with elevated central sympathetic drive. The renal nerves may be located and targeted at the level of the ganglion and/or at postganglionic positions, as well as preganglionic positions. Target regions include the renal plexus, celiac ganglion, the superior mesenteric ganglion, the aorticorenal ganglion and the aortic plexus. Planning of radiosurgical treatments will optionally employ a graphical representation of a blood/tissue interface adjacent these targets.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for reducing the difference in performance of a model across groups and sub-groups within the same group of users with similar characteristics for providing digital components. Methods can include identifying, a loss function that generates a loss representing a measure of performance the model seeks to optimize during training. The loss function is modified by adding an additional term to the loss function. The model is trained using the modified loss function. A request for digital component is received that includes a user group identifier. The model generates one or more user characteristics based on which one or more digital components are selected and transmitted to the client device of the user.

Abstract: A DNS security system collects and uses aggregated DNS information originating from a plurality of client computers to detect anomalous DNS name resolutions. A server DNS security component receives multiple transmissions of DNS information from a plurality of client computers, each transmission of DNS information concerning a specific instance of a resolution of a specific DNS name. The server component aggregates the DNS information from the multiple client computers. The server component compares DNS information received from a specific client computer concerning a specific DNS name to aggregated DNS information received from multiple client computers concerning the same DNS name to identify anomalous DNS name resolutions. Where an anomaly concerning received DNS information is identified, a warning can be transmitted to the specific client computer from which the anomalous DNS information was received.

Abstract: A computer-implemented method for blocking and removing Internet-traversing malware may include: 1) identifying a persistent storage object of an Internet client application, 2) identifying an attempt by an executable object to access the persistent storage object, 3) determining that the executable object is not authorized to access the persistent storage object, and then 4) performing a security action based on the determination. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Incoming network traffic is monitored, and content-based files in the monitored incoming network traffic originating from remote sources are identified. When a specific content-based file originating from a remote source is identified, security information concerning that file is gleaned. This security information comprises at least a security reputation of the remote source from which the file originates. An attempt to open the file is identified, and a security risk rating is determined based on the security information concerning the file. In response to the security risk rating exceeding a given threshold, behavior associated with the attempt to open the file is altered. This altering of behavior can comprise, for example, disabling a scripting engine for the instance of the content processing application attempting to open the file, or altering file system and/or operating system resource access privileges.

Abstract: A financial portfolio management system operable in a network environment can be configured to gather financial information from a plurality of sources over an electronic network and intelligently aggregate the information into a financial portfolio viewable by a client. The client can determine which accounts should be included in the portfolio. The system uses web crawling, parsing, or spidering technology to update the portfolio information. The system provides one platform that conveys financial information from a variety of accounts held at several different financial institutions.

Abstract: A computer-implemented method for individually managing the power usage of software applications may include: 1) identifying at least one software application installed on a computing device, 2) determining the power usage of the software application, 3) identifying a power-management policy for managing the power usage of the software application independent of the overall power usage of the computing device, and then 4) managing the power usage of the software application independent of the overall power usage of the computing device in accordance with the power-management policy. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A computer system detects and selectively blocks a cookie associated with a website. The system monitors a network traffic stream directed to a client from a website and detects presence of a cookie associated with the website in the network traffic stream. The system detects the cookie in the network traffic stream by analyzing the network stream using a network traffic filtering scheme, such as a deep packet inspection engine. The system further determines a reputation of the website in response to detecting the cookie in the network traffic stream. A reputation of a website represents an assessment of whether the website is trustworthy. Based on the determined reputation of the website, the system selectively blocks the cookie from being stored in the client if the reputation of the website is bad.

Abstract: A user mode application component invokes the assistance of a kernel mode driver component to detect and/or remediate malicious code on a computer system. The user mode application may include code that detects, for example, spyware and computer viruses, from user mode and when appropriate takes protective action when malicious code is detected. In one aspect, when the user mode application is unable to perform a selected operation in attempting to detect and/or take protective action, the user mode application invokes a kernel mode driver for assistance. The kernel mode driver assists user mode application in detecting malicious code and/or taking protective action by enabling or otherwise performing a selected operation for the user mode application.

Abstract: A network communication corresponding to a malicious network signature associated with malicious code is detected on a host computer system. A determination is made whether or not the malicious network signature is validated as associated with a non-malicious code process. Upon a determination that the malicious network signature is not validated, the corresponding network communication is blocked, and the associated malicious code is located on the host computer system and removed from the host computer system. In some embodiments, the host computer system is further evaluated for the presence of residual artifacts of the malicious code on the host computer system.
