We study complete cohomology of complexes with finite Gorenstein AC-projective dimension. We show first that the class of complexes admitting a complete level resolution is exactly the class of complexes with finite Gorenstein AC-projective dimension. This lets us give some general techniques for computing complete cohomology of complexes with finite Gorenstein AC- projective dimension. As a consequence, the classical relative cohomology for modules of finite Gorenstein AC-projective dimension is extended. Finally, the relationships between projective dimension and Gorenstein AC-projective dimension for complexes are given.

For projects with thousands of files, finding the locations of bugs is time-consuming and labor-intensive. Bug reports as a potential resource to help locate bugs in source codes have been used to design automatic tools to solve this problem. Existing information retrieval(IR)-based bug localization methods rely heavily on the similarity score between bug report and historical reports. As deep learning methods show great advantages in calculating text semantic similarity, we adapt the transformer network with IR-based bug localization methods to design a novel approach, TSLocator, to bug localization. In TSLocator, we propose five new features between bug reports and source codes. We use SVMRank to model the relation between all the six features and the actual buggy file. Given a new bug report, TSLocator automatically calculates the features and linearly weights the features to produce a suspicious score for all candidate files. TSLocator recommends a list of suspicious buggy files ranked by the score. The experimental results show that TSLocator outperforms existing methods in accuracy and performance of bug localization.

The developing human and mouse teeth constitute an ideal model system to study the regulatory mechanism underlying organ growth control since their teeth share highly conserved and well-characterized developmental processes, and their developmental tempo varies notably. In the current study, we manipulated heterogenous recombination between human and mouse dental tissues and demonstrated that the dental mesenchyme dominates the tooth developmental tempo and FGF8 could be a critical player during this developmental process. Forced activation of FGF8 signaling in the dental mesenchyme of mice promoted cell proliferation, prevented cell apoptosis via p38 and perhaps PI3 K-Akt intracellular signaling,and impelled the transition of the cell cycle from G1-to S-phase in the tooth germ, resulting in the slowdown of the tooth developmental pace. Our results provide compelling evidence that extrinsic signals can profoundly affect tooth developmental tempo, and the dental mesenchymal FGF8 could be a pivotal factor in controlling the developmental pace in a non-cell-autonomous manner during mammalian odontogenesis.

We obtain the H?lder continuity and joint H?lder continuity in space and time for the random field solution to the parabolic Anderson equation ■ in d-dimensional space, where ■ is a mean zero Gaussian noise with temporal covariance γ0 and spatial covariance given by a spectral density μ(ξ). We assume that ■ and ■ , where αi, i = 1, · · ·, d(or α) can take negative value.
