The northern terrestrial net ecosystem carbon balance (NECB) is contingent on inputs from vegetation gross primary productivity (GPP) to offset the ecosystem respiration (Reco) of carbon dioxide (CO2) and methane (CH4) emissions, but an effective framework to monitor the regional Arctic NECB is lacking. We modified a terrestrial carbon flux (TCF) model developed for satellite remote sensing app...
We define a closure operation for ideals in a commutative ring which has all the good properties of solid closure (at least in the case of equal characteristic) but such that also every ideal in a regular ring is closed. This gives in particular a kind of tight closure theory in characteristic zero without referring to positive characteristic.
Beta-catenin is the vertebrate homolog of the Drosophila segment polarity gene Armadillo and plays roles in both cell-cell adhesion and transduction of the Wnt signaling cascade. Recently, members of the Lef/Tcf transcription factor family have been identified as protein partners of beta-catenin, explaining how beta-catenin alters gene expression. Here we report that in T cells, Tcf-1 also beco...
PURPOSE Aberrantly activated Wnt/β-catenin signaling is important in hepatocellular carcinoma (HCC) development. Downstream gene expressions involving the Wnt/β-catenin cascade occur through T-cell factor (TCF) proteins. Here, we show the oncogenic potential of human TCF-4 isoforms based on the expression of a single conserved SxxSS motif. METHODS We investigated the TCF-4J and K isoform pair...
This paper presented a regrasp planning method to eliminate grasp uncertainty while considering the geometric constraints of fixture. The automatically finds Stable Placement Poses (SPPs) an object on Triangular Corner Fixture (TCF), elevates from its SPPs dropping poses and Deterministic Dropping (DDPs), builds graphs by using SPP-DDP pairs their associated configurations, searches graph find ...
Data sparsity due to missing ratings is a major challenge for collaborative filtering (CF) techniques in recommender systems. This is especially true for CF domains where the ratings are expressed numerically. We observe that, while we may lack the information in numerical ratings, we may have more data in the form of binary ratings. This is especially true when users can easily express themsel...
