摘要： Embodiments of methods, systems, and tangible non-transitory computer readable medium having instructions are presented. A method includes calculating a plurality of feature values for a number of bioinformatic features of the desired hybridization reaction; and calculating distances between the plurality of feature values and corresponding database rate constant values stored in a database, the database comprising a plurality of hybridization reactions having known rate constants. The method additionally includes calculating a weighted average of a logarithm of the database rate constant values, with larger weights assigned to value instances having values lower in distance to the plurality of feature values of the desired hybridization reaction; and providing the weighted average as a predicted logarithm of the rate constant of the desired hybridization reaction.

摘要： Systems, methods and apparatus, including computer program products, are disclosed for regulating access of consumers (e.g., applications, containers, or VMs) to resources and services (e.g., storage). In one embodiment, this regulation occurs through the movement of consumers between different providers of a resource or service, such as a cloud service provider. Moving consumers includes, for example, determining the cost of moving the consumer from a first provider to a second provider. According to various embodiments, the cost of moving the consumer is compared to cost and performance criteria associated with moving the consumer from the first provider to the second provider. Cloud-based services may be priced as templates, reserved instances, or a combination.

摘要： The high conductivity energy-saving clamping device comprises a clamp and a cable fixed upon the clamp. Inside the cable, the conductive material protrudes and is set on the juncture of the clamp and the external conductor. When the clamp is connected to the external conductor, the conductive material and the external conductor contact and meet. This invention possesses the following advantages: it simplifies the production technology, lessens raw materials needed for production and hence saves resources and cost by the direct contact of the conductive material and the external conductor; moreover, due to the increase of conductive contact area, it enhances the electrical conductivity by 10% to 15% compared to those common clamps which use tooth-like conductive parts to connect the external conductor. Meanwhile, the invention greatly decreases environmental pollution by omitting the plating process of tooth-like conductive parts.

摘要： A Reduced Instruction Set Computing (RISC) processor is capable of emulating operation of a floating-point register stack. The RISC processor may include a floating-point register file containing a plurality of floating-point registers, a decoding section for decoding operation instructions, and a floating-point operation section. The RISC processor may also include a control register for controlling status of floating-point registers, and for controlling the decoding section and the floating-point operation section, to thereby emulate a floating-point register stack using the floating-point register file. The decoding section may include a pointer register for maintaining a stack operation pointer, and for storing a value of the stack operation pointer. The floating-point operation section may also include a pointer operation module for operating the pointer register, for emulating stack operation of the stack pointer of the pointer register, and for modifying and monitoring the stack pointer during emulation of floating-point register stack.
