Abstract: Embodiments of the present disclosure provide techniques for efficient computation over a wide table. A processing device determines that a first number of columns of a first table is greater than a threshold number of columns. The processing device transforms the first table into a second table based on the determination, where the second table includes a second number of columns that is less than the first number of columns, and where the second table includes a first column that includes first fields that identify columns of the first table, a second column that includes second fields that identify data types of fields of the first table, and a third column that includes third fields that include data of the fields of the first table. The processing device executes a UDTF on the second table.

Abstract: Systems and methods are provided for classifying data. The systems and methods access an automatic classification profile comprising one or more conditions for triggering data classification and access a classification scope that identifies one or more tables to be classified. The systems and methods determine that a set of attributes of the one or more tables identified by the classification scope corresponds to the one or more conditions of the automatic classification profile. The systems and methods, in response to determining that the set of attributes of the one or more tables identified by the classification scope corresponds to the one or more conditions of the automatic classification profile, automatically classify data stored in one or more columns of the one or more tables.

Abstract: Devices, methods, computer-readable media, and systems with authorized fraud detection. In one example, a device may include a memory including an input profile record (IPR) repository and a non-input profile record (non-IPR) information repository that is distinct from the IPR repository, and an electronic processor in communication with the memory. The electronic processor is configured to receive a current IPR associated with a user entering information to transfer electronic funds, detect that the user is performing authorized fraud based on the current IPR, and responsive to detecting that the user is performing authorized fraud based on the current IPR, output a control signal indicating that the user is performing authorized fraud.

Abstract: The present disclosure describes systems, methods, and computer program products for redacting sensitive data within a database. An example method can include sending, to a database, a data query accessing a column of the database, a masking policy identifying a first category of sensitive data and a second category of sensitive data, and in response to the data query, receiving redacted data, wherein the first category of sensitive data is redacted from a first location of the column by a first redaction operation and the second category of sensitive data is redacted from a second location of the column by a second redaction operation.

Abstract: A method for deoxygenation of an oxygen-containing hydrocarbon, such as a bio-crude liquid, in the presence of a methane-containing gas and a catalyst structure, is described. The method results in a reduction of oxygen content within the hydrocarbon.

Abstract: The present disclosure includes: transforming a time-domain voltage signal collected by an MPI system device to a frequency domain; calculating a square root of a square sum of a real part and an imaginary part at each frequency point of a frequency domain signal; arranging acquired amplitudes in a descending order, and acquiring a screening threshold by an amplitude ratio method; screening an amplitude through the screening threshold and constructing frequency domain signal data; acquiring a row vector of a system matrix corresponding to each frequency point of the data, so as to construct an update system matrix; and solving, based on the frequency domain signal array and the update system matrix, an inverse problem in a form of a least square based on an L2 constraint to obtain a three-dimensional magnetic particle concentration distribution result, so as to achieve a fast reconstruction of the MPI system.

Abstract: Systems and methods for classifying columns using a model are provided. The systems and methods access a table associated with a column of features and retrieve a list of categories each associated with a different scoring model. The systems and methods, for each category in the list of categories, apply a respective scoring model to the features of the column to generate a respective set of confidence values indicating a likelihood that the column belongs to a respective one of the categories. The systems and methods process the respective sets of confidence values to select a target category from the list of categories and associate the selected target category with the column.

Abstract: A liquid composite spring and a method for adjusting stiffness and damping property of the liquid composite spring such that the liquid composite spring includes an outer sleeve; a core shaft arranged around an upper portion of the outer sleeve. An upper portion of the core shaft is located inside the outer sleeve, while a lower portion extends out of the outer sleeve; an upper liquid chamber formed in an upper space inside the outer sleeve and having a lower portion connected to a top end of the core shaft; and a lower liquid chamber formed in a lower space inside the outer sleeve and connected with the core shaft. The core shaft has a damping flow channel arranged therein, for communicating liquid in the upper liquid chamber with liquid in the lower liquid chamber. The liquid composite spring can provide vibration-reducing effect and change stiffness and damping effect.
