Artesunate Nanoplatform Targets the Serine–MAPK Axis in Cancer‐Associated Fibroblasts to Reverse Photothermal Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Materials, EarlyView.
The artesunate nanoplatform selectively targets ECM CAF, functioning as a GTPase inhibitor through disruption of intracellular serine homeostasis. This metabolic intervention effectively suppresses MAPK cascade activity, which consequently inhibits PTT‐induced CAF to ECM CAF differentiation.

Moving up and down in the generic multiverse

open access: yes, 2012
We give a brief account of the modal logic of the generic multiverse, which is a bimodal logic with operators corresponding to the relations "is a forcing extension of" and "is a ground model of".

Relating Reasoning Methodologies in Linear Logic and Process Algebra [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
We show that the proof-theoretic notion of logical preorder coincides with the process-theoretic notion of contextual preorder for a CCS-like calculus obtained from the formula-as-process interpretation of a fragment of linear logic.

The Rise of Refractory Transition‐Metal Nitride Films for Advanced Electronics and Plasmonics

open access: yesAdvanced Materials Interfaces, EarlyView.
Transition‐metal nitrides (TMNs) are exceptional materials with high stability, biocompatibility, and semiconductor integration, which have been extensively employed in various fields. However, the epitaxial growth of TMN films remains a challenge. The absence of high‐quality TMNs limits the understanding of their condensed matter physics and hinders ...

Deciding regular grammar logics with converse through first-order logic

open access: yes, 2003
We provide a simple translation of the satisfiability problem for regular grammar logics with converse into GF2, which is the intersection of the guarded fragment and the 2-variable fragment of first-order logic.

Ordered fragments of first-order logic

open access: yes, 2021
Using a recently introduced algebraic framework for the classification of fragments of first-order logic, we study the complexity of the satisfiability problem for several ordered fragments of first-order logic, which are obtained from the ordered logic and the fluted logic by modifying some of their syntactical restrictions.

Chemoselective Synthesis of α‐Chloro and α,α‐Dichloro Acetamidines via the Carbenoids Addition to Inherently Low Electrophilic Carbodiimides

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Carbodiimides act as competent electrophilic synthons for the chemoselective addition of lithium mono‐ and di‐halocarbenoids. The transformation is provided through a single synthetic operation—hitherto elusive—halogenated acetamidines. Interestingly, the constitutively tamed electrophilicity of the starting materials is effectively counterbalanced by ...

The Systems of Relevance Logic [PDF]

open access: yesArgument, 2011
The system R, or more precisely the pure implicational fragment R→, is considered by the relevance logicians as the most important. The another central system of relevance logic has been the logic E of entailment that was supposed to capture strict ...
