Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Towards a Context-Free Machine Universal Grammar (CF-MUG) in Natural Language Processing
IEEE Access, 2020 In natural language processing, semantic document exchange ensures unambiguity and shares the same meaning for documents sender and receiver cross different natural languages (e.g., English to Chinese), this difference makes the translation between ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

The categorical contours of the Chomsky-Sch\"utzenberger representation theorem [PDF]
Logical Methods in Computer ScienceWe develop fibrational perspectives on context-free grammars and on nondeterministic finite-state automata over categories and operads. A generalized CFG is a functor from a free colored operad (aka multicategory) generated by a pointed finite species ...

!-Graphs with Trivial Overlap are Context-Free [PDF]
Electronic Proceedings in Theoretical Computer Science, 2015 String diagrams are a powerful tool for reasoning about composite structures in symmetric monoidal categories. By representing string diagrams as graphs, equational reasoning can be done automatically by double-pushout rewriting.

Molecular Oncology, EarlyView.Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

Temporal Logic and Model Checking for Operator Precedence Languages [PDF]
Electronic Proceedings in Theoretical Computer Science, 2018 In the last decades much research effort has been devoted to extending the success of model checking from the traditional field of finite state machines and various versions of temporal logics to suitable subclasses of context-free languages and ...

گۆڤارا زانستێن مرۆڤایەتی یا زانكۆیا زاخۆ, 2023 The main purpose of this study is to present the derivational process in the analysis of Kurdish and Persian words from the perspective of the morpheme-based morphological theory of how morphemes are arranged together to form words.

Information and Control, 1974 In an earlier paper (Santos, 1973b), the author introduced two distinct but equivalent formulations of max-product grammars. One corresponds to the maximal interpretation (Salomaa, 1969) of probabilistic grammars (Santos, 1972), while the other provides a grammar for generating fuzzy languages (Santos, 1973a). Various types of max-product grammars were

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma
Molecular Oncology, EarlyView.Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...
