Abstract: The present disclosure relates to an information providing method for an on-demand service. The method may include receiving service request information from a passenger of a passenger terminal device. The service request information may include a departure location of the passenger. The method may further include acquiring historical service request information related to the passenger; and determining travel-route-related information based at least in part on the departure location of the passenger and the historical service request information. Also disclosed is a system for implementing the method.

Abstract: Disclosed is an infrared ray positioning node device, including a reflection cup with a plurality of side surfaces; and an infrared ray emitting tube cooperating with the reflection cup and being positioned so that the range of an included angle m formed after the rays emitted by the infrared ray emitting tube reflect off some reflection side surfaces in the plurality of side surfaces is 0°?m<180°. Also disclosed is an infrared ray positioning node system. The present invention makes the direction of an infrared ray emission signal controllable in the range of 0°-180°, makes the signal stable and even in intensity, improves the radiation utilization of the infrared ray emitting tube, reduces the power consumption of the node device, realizes uniform projection of infrared light, and effectively avoids emission blind areas of a single node and signal interference between adjacent nodes.

Abstract: The present disclosure relates to a method for predicting an order value. The method includes: obtaining information, wherein the information includes a historical order; determining an attribute feature of the historical order based on the information; and predicting the order value based on the attribute feature. The present disclosure also relates to a system for predicting the order value. The system includes a receiving module and a processing module, wherein the processing module is configured to predict the order value.

Abstract: The present disclosure provides methods and apparatus for executing integrated application programs. An implementation class of an instantiation application program is executed in a first process, to obtain a context of a first application program including a first identifier. Or an implementation class of an instantiation application program is executed in a second process, to obtain a context of a second application program including a second identifier. It is determined whether an identifier corresponding to a current process is the first identifier or the second identifier. If the identifier corresponding to the current process is the first identifier, the first application program is executed when an initialization starts. Or, if the identifier corresponding to the current process is the second identifier, the second application program is executed when an initialization starts.

Abstract: The subject matter disclosed herein pertains to the modulation of a bacterial invasion switch and the subsequent use of the bacterium to vaccinate an organism. In one embodiment, the bacterial invasion switch is modulated by changing the proteolysis of ExoR protein. In another embodiment, a mutated bacterium produces a mutant ExoR protein that resists proteolysis.
