    Abstract: A computer-implemented method for modifying file backups in response to detecting potential ransomware may include (1) detecting, during a file backup process, an anomaly that is potentially indicative of ransomware on a computing device, (2) in response to detecting the anomaly that is potentially indicative of ransomware, storing a backup copy in a separate location from other backup copies, (3) confirming that the anomaly is indicative of ransomware on the computing device, (4) adjusting a backup policy in response to confirming that the anomaly is indicative of ransomware on the computing device, and (5) managing the backup copy based on the adjusted backup policy. Various other methods, systems, and computer-readable media are also disclosed.

  • Publication number: 20170191887
    Abstract: An apparatus (100, 200, 300) and a method for measuring residual torsions of an elongated structure (202) such as a steel cord use a pivot head (102). The pivot head (102) comprises a wheel (104) adapted to guide an elongated structure (202). The wheel (104) is mounted in the pivot head (102) to transmit torques exercised by the elongated structure (202) on the wheel (104) to the pivot head (102). The pivot head (102) is mounted along a pivotal axis (110). This pivotal axis (110) lies in a plane of the wheel (104) and comprises the centre of the wheel (104). Sensor means (116, 206) measure the torque on the pivot head (102). The pivotal movement of the pivot head (102) around the pivotal axis (110) is limited to an angle range of ±5°, preferably ±3° in order to reach an improved accuracy of the torque measurement.

  • Publication number: 20170140156
    Abstract: The disclosed computer-implemented method for protecting backed-up data from ransomware attacks may include (1) determining that a backup system periodically backs up at least one file stored at a computing device to a remote storage system by storing a copy of the file at the remote storage system, (2) identifying one or more characteristics of the file backed up by the backup system, (3) storing a tripwire file with the one or more characteristics at the computing device, (4) determining that the file stored at the computing device has likely been encrypted by ransomware executing on the computing device by detecting that the tripwire file has been modified, (5) performing an action that prevents the backup system from replacing the copy of the file at the remote storage system with a copy of the encrypted file. Various other methods, systems, and computer-readable media are also disclosed.

  • Publication number: 20170074742
    Abstract: A pressure sensor may measure gas or liquid pressure. A chamber may have an inlet that receives the gas or liquid. A flexible diaphragm may be within the chamber that has a surface exposed to the gas or liquid after it flows through the inlet. A pressure sensor system may sense changes in the flexible diaphragm caused by changes in the pressure of the gas or liquid. A pressure-insensitive sensor system may sense changes in the flexible diaphragm that are not caused by changes in the pressure of the gas or liquid. The pressure-insensitive sensor system may be insensitive to changes in the flexible diaphragm caused by changes in the pressure of the gas or liquid.

  • Publication number: 20170071941
    Abstract: The invention provides the identification of the presence of mutant ROS protein in human cancer. In some embodiments, the mutant ROS are FIG-ROS fusion proteins comprising part of the FIG protein fused to the kinase domain of the ROS kinase. In some embodiments, the mutant ROS is the overexpression of wild-type ROS in cancerous tissues (or tissues suspected of being cancerous) where, in normal tissue of that same tissue type, ROS is not expressed or is expressed at lower levels. The mutant ROS proteins of the invention are anticipated to drive the proliferation and survival of a subgroup of human cancers, particularly in cancers of the liver (including bile duct), pancreas, kidney, and testes. The invention therefore provides, in part, isolated polynucleotides and vectors encoding the disclosed mutant ROS polypeptides (e.g., a FIG-ROS(S) fusion polypeptide), probes for detecting it, isolated mutant polypeptides, recombinant polypeptides, and reagents for detecting the fusion and truncated polypeptides.

  • Patent number: 9523130
    Abstract: Novel gene deletions and translocations involving chromosome 2 resulting in fusion proteins combining part of Anaplastic Lymphoma Kinase (ALK) kinase with part of a secondary protein have been identified herein in human solid tumors, e.g. non-small cell lung carcinoma (NSCLC). Secondary proteins include Echinoderm Microtubule-Associated Protein-Like 4 (EML-4) and TRK-Fusion Gene (TFG). The EML4-ALK fusion protein, which retains ALK tyrosine kinase activity, was confirmed to drive the proliferation and survival of NSCLC characterized by this mutation. The invention therefore provides, in part, isolated polynucleotides and vectors encoding the disclosed mutant ALK kinase polypeptides, probes for detecting it, isolated mutant polypeptides, recombinant polypeptides, and reagents for detecting the fusion and truncated polypeptides.
