Abstract: A distributed parallel processing database that processes data in a Java environment allocates memory both on a Java heap and off a Java heap. The distributed parallel processing database includes multiple servers. Each server executes a Java virtual machine (JVM) in which data allocated to the server is processed. When a JVM of a server starts, the JVM can specify an off-heap memory size, based on a JVM start parameter. The server can designate memory of the specified size that is off JVM memory heap as off-heap memory. The off-heap memory is different from heap memory in the Java environment, and is managed by a garbage collector that is outside of the Java environment. The server can process data designated as off-heap memory eligible in the off-heap memory. The off-heap memory can improve database operations that create a large number of similar-sized objects in memory by reducing Java memory management overhead.

Abstract: In one aspect, the present disclosure is directed to a bearing compartment sealing system including a bearing for supporting a shaft. A housing encloses the bearing and defines a compartment for holding lubricant therein. At least two seals are located between the shaft and the housing. The at least two seals, the housing, and the shaft collectively enclose the compartment. Only one of the at least two seals is a hydrodynamic seal.

Abstract: A computer-implemented method for maintaining encrypted search indexes on third party storage systems may include (1) identifying a plurality of encrypted files, (2) identifying a plurality of keywords contained in the plurality of encrypted files, and (3) generating an encrypted search index for searching the plurality of encrypted files by (i) identifying, for each keyword in the plurality of keywords, a list of encrypted files in the plurality of encrypted files that contain the keyword, (ii) encrypting the list of encrypted files, and (iii) storing the encrypted list of encrypted files such that the encrypted list of encrypted files can be identified using a lookup key generated by applying a pseudo-random function to the keyword. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Provided herein are devices, systems, apparatus and methods for accessing the cervical spine via an anterior approach and implanting a spinal fixation member between two vertebrae of the cervical spine in the disc or intervertebral joint space, such as in an ACDF procedure. The delivery device includes a distal end that can be anchored to the spinal fixation member. Once anchored to the spinal fixation member, the delivery device is operable to both advance and attach the spinal fixation member within a cervical disc joint space.

Abstract: A bearing support housing for a gas turbine engine includes: an annular mounting flange; a first bearing cage including: an annular first bearing support ring; and an annular array of axially-extending first spring arms interconnecting the first bearing support ring and the mounting flange; and a second bearing cage including: an annular second bearing support ring; and an annular array of axially-extending second spring arms interconnecting the second bearing support ring and the mounting flange, the second spring arms defining spaces therebetween. The first spring arms are received between the second spring arms, and the bearing cages are sized so as to permit independent flexing motion of the first and second spring arms.
