, 1999 An important theorem of Gross and Tucker characterises a directed graph $E$ which admits a free action of a group as a skew product. Here we extend this to directed graphs admitting free actions of semigroups, $S$, under certain hypotheses. Indeed, the main criterion we employ can be completely characterised by properties of the quotient map $E ...

A contribution to the theory of voltage graphs
Discrete Mathematics, 1986 This paper studies several problems in voltage graph theory (useful in constructing graph imbeddings), such as equivalence and regularity of coverings generated by (permutation) voltage graphs, and automorphism groups. To consider a sample result, let \(\chi\) be either an ordinary voltage assignment (OVA) or a permutation voltage assignment (PVA ...

Molecular Oncology, EarlyView.HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

ANALYSIS OF INDICATORS OF RELIABILITY OF ELECTRICAL NETWORKS
Problems of the Regional Energetics, 2012 Problems of the optimization reliability in electrical networks of the different class of voltage have probabilistic nature, they discretely change and depend on the number of factors both definite and indefinite and have importance by selection of ...

Fiber optic frequency transfer link [PDF]
, 1991 A reference frequency distribution system is disclosed for transmitting a reference frequency from a reference unit to a remote unit while keeping the reference frequency at the reference unit and the remote unit in phase.

Molecular Oncology, EarlyView.Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Dual targeting of RET and SRC synergizes in RET fusion‐positive cancer cells
Molecular Oncology, EarlyView.Despite the strong activity of selective RET tyrosine kinase inhibitors (TKIs), resistance of RET fusion‐positive (RET+) lung cancer and thyroid cancer frequently occurs and is mainly driven by RET‐independent bypass mechanisms. Son et al. show that SRC TKIs significantly inhibit PAK and AKT survival signaling and enhance the efficacy of RET TKIs in ...
