Abstract: Managing source code change set commits to decrease time to identify software bugs in versions of a software project is provided. An initial order of relevant commits corresponding to the software project is determined in a priority queue based on a weight of each respective commit of the relevant commits. The initial order of the relevant commits is adjusted in the priority queue based on a build distance between the relevant commits of affected source files. A particular commit having a highest priority ranking is selected in the priority queue for build and test. The build and the test of the particular commit having the highest priority ranking in the priority queue is executed.

Abstract: A method, computer system, and a computer program product for improving debugging speed by rearranging debugging priority functions. In one embodiment, runtime input may be received about a program to be debugged. Feedback information is obtained about at least one similar program previously debugged. The compiling time information and runtime information are analyzed to determine a status of functions including one or more focused functions that will be used frequently and one or more unreachable functions that may never will be executed. A priority list of debugging functions is generated based on the feedback information, the runtime input and a function status. A plurality of debugging information are rearranged and parsed on the priority list prior to said program being debugged based on said debugging information.

Abstract: The present application relates to SARS-CoV-2 virus-like particles (VLP) and related plasmids, compositions, and methods. The VLP can comprise a modified spike glycoprotein, a matrix protein, a nucleoprotein N and an envelope protein of SARS-CoV-2, where the modified spike glycoprotein comprises an S1 domain and an S2 domain, and includes one or more modifications. These modifications can include: linking the S1 and S2 domains via generation of disulfides bonds between the S1 and S2 domains; linking intra-polypeptide and inter-polypeptide S2 helices of the S2 domain; and substitution of one or more non-cysteine residues with a cysteine residue to generate one or more disulfide bonds. The modifications can stabilize a prefusion conformation of the spike glycoprotein and prohibit a transition to a post-fusion structure.

Abstract: The present invention includes a live, self-attenuated therapeutic vaccine, virus and methods of making and using the same, comprising: an isolated virus comprising a viral genome that expresses one or more viral antigens; and an artificial microRNA 30 (amiR-30) expression cassette inserted into a viral neuraminidase (NA) or a viral non-structural (NS) gene segment that expresses an amiR-30 that specifically inhibits the expression of a host gene essential for influenza virus replication in host cells.

Abstract: Provided herein is a mammalian expression system for producing recombinant porcine circovirus type 2 (PCV2) virus-like particles (VLPs). The expression system includes a mammalian cell and a plasmid that comprises a PCV2 gene encoding a capsid protein. The PCV2 gene is codon optimized, and the mammalian cell is transfected with the plasmid. The expression system produces recombinant PCV2 VLPs, such as PCV2d VLPs. Also provided herein are a method for producing porcine circovirus type 2 (PCV2) virus-like particles (VLPs), as well as a PCV2 VLP generated by the method.

Abstract: Embodiments of the present disclosure relate to runtime type identification (RTTI) of an object. In an embodiment, a computer-implemented method is disclosed. A class inheritance relationship between a plurality of classes in at least one source code section is generated. Respective type identifications are assigned to identify the classes in the class inheritance relationship. In accordance with presence of a first operation related to accessing a target pointer to an object of a target class of the classes, a type identification for the target class is caused to be recorded with at least one bit of a memory address of the target pointer that can be omitted in addressing the target pointer. RTTI is caused to be performed based on the class inheritance relationship and the at least one bit of the memory address of the target pointer. In other embodiments, a system and a computer program product are disclosed.

Abstract: Embodiments of the present invention may track a user's interaction trajectory associated with a problem occurred on a website. According to an embodiment of the present invention, a first symbol of a first definition associated with a first object file is obtained. Then, in response to the first symbol matching a second symbol of a second definition associated with a second object file, the first object file is optimized based on a first segment associated with the first definition in the first object file and an optimization to the second object file is skipped. Next, an executable file is generated based on the optimized first object file and the second object file.
