Logic and Ontology

Principia: An International Journal of Epistemology, 2002
In view of the present state of development of non classical logic, especially of paraconsistent logic, a new stand regarding the relations between logic and ontology is defended In a parody of a dictum of Quine, my stand May be summarized as follows. To

Organ‐Specific and Conserved Regulatory Logic Orchestrates Gene Expression in the Embryonic Mesothelium

Advanced Science, EarlyView.
Integrated multi‐omic profiling maps the gene‐regulatory landscape of the coelomic mesothelium across heart, lung, and pancreas. A cardiac‐restricted regulatory program is uncovered in which TBX20 activates heart mesothelial (epicardial) cis‐regulatory elements, while MAF emerges as a conserved regulator of mesothelial identity.

Logic as a Key to Interdisciplinary Integration for Students in the Mathematical Sciences [PDF]

Journal of Systemics, Cybernetics and Informatics, 2017
We describe the creation and development of a course on mathematical logic and its extensions and limitations, in which coverage of technical material is interleaved with and related to discussion of relevant historical, linguistic, philosophical, and ...

On relationships between the logic of law, legal positivism and semiotics of law

Sign Systems Studies, 2011
The issue of reciprocal relationships between the logic of law, positivistic theory of the logic of law, and legal semiotics is among the most important questions of the modern theoretical jurisprudence.

Synergistic Mn‐MOF Activation of Pistol Ribozymes for Cancer Immunotherapy

Advanced Science, EarlyView.
A Mn2+‐based metal–organic framework delivers a catalytic Pistol ribozyme for targeted PD‐L1 mRNA cleavage in tumor cells, with the released Mn2+ not only inducing immune activation in immune cells but also increasing the Pistol ribozyme catalytic activity.

WUSCHEL Transcription Factor: From Stem Cell Maintenance to Crop Improvement

Advanced Science, EarlyView.
This review synthesizes emerging insights into WUSCHEL (WUS) as a central regulator of plant stem cell fate beyond Arabidopsis, highlighting its roles in regeneration, somatic embryogenesis (SE), and stress adaptation across crops. It explores how WUS‐centered regulatory networks, genome editing, and AI‐guided strategies can be leveraged for precise ...

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Postsynaptic Complexin Mediates Constitutive Exocytosis of Nicotinic Acetylcholine Receptor

Advanced Science, EarlyView.
Beyond its established presynaptic role, complexin is identified as a postsynaptic regulator of neurotransmitter receptor trafficking. By promoting constitutive and activity‐dependent exocytosis of nicotinic acetylcholine receptors, complexin controls spontaneous synaptic signaling at the C.

Dysregulation of the PATZ1/CTCF Balance Silences ZBTB20 to Drive Melanoma Progression

Advanced Science, EarlyView.
This study uncovers a new oncogenic mechanism in melanoma. The transcription factor PATZ1 competes with the architectural protein CTCF for DNA binding, thereby disrupting a specific chromatin loop and silencing the tumor suppressor ZBTB20. This event unleashes the pro‐tumorigenic PMEPA1‐p38‐STAT1 signaling axis, promoting cancer progression.
