Abstract: The present application provides a load balancing system. In an example, the load balancing system includes a client, a first load balancer coupled to the client, a plurality of security forwarding devices whose load sides are coupled to the first load balancer and forwarding sides are coupled to a second load balancer, the second load balancer, and a server coupled with the second load balancer. In the load balancing system, service traffic resources can be accurately allocated to the target security forwarding device selected by the scheduling algorithm, so as to balance load.

Abstract: A method may include: generating a database query to retrieve a first set of records from a database, the database query retrieving the first set of records by filtering, based on a target value, records held at the database, the records being associated with at least one attribute; selecting a subset of records from the first set of records, the selecting based on an attribute associated with the first set of records; modifying the target value in response to the attribute associated with the subset of records failing to satisfy a threshold value; executing a modified database query to retrieve a second set of records from the database, the modified database query retrieving the second set of records by filtering, based on the modified target value, the records at the database; and generating a user interface configured to display a result of the database query and/or the modified database query.

Abstract: A sensing device and method in detecting binding energy and binding kinetics between molecules; the sensing device has a sensor, a microfluidic chip and a measurement circuit. The sensor has multiple field effect transistors, and each field effect transistor adopts single-layer single crystal graphene as a conductive channel, thereby having extremely high sensitivity and stability; and the field effect transistors are arranged in an array and are provided with multichannel measurement circuits to detect the binding dynamics processes of different molecules or different copies of the same molecule in parallel so as to meet the high-throughput detection requirements. A compound that is non-covalently bound with the single-layer single crystal graphene as a medium to fix probe molecules on the surface of the conductive channel, thereby retaining the intrinsic structure of the graphene, and improving the signal-to-noise ratio and the sensitivity of the graphene field effect transistor.

Abstract: A rules engine is provided that can work with various heterogeneous calling applications. Such a rules engine can be part of a larger framework which, for example, can provide calibration alerts and the like when certain rule conditions are met. In some implementations, the framework can allow for the identification and mitigation of bias against certain employees and/or classes of employees within a larger organization.

Abstract: A system and method are disclosed for edge blending hard drive head sliders by oscillating abrasive lapping tape across the edges of multiple sliders simultaneously. Lapping tape is inserted between each of a number of head sliders bonded to a edge blending jig of an edge blending assembly. The edge blending assembly is adjusted to cause the lapping tape to partially wrap an edge of each slider. The head sliders are edge blended by the relative movement between the sliders and the lapping tape.
