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.

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

Polylactic Acid (PLA), Polycaprolactone (PCL), and Chitosan: the Biodegradable Transition in Medical Waste Management

open access: yesAdvanced Sustainable Systems, EarlyView.
The shift to biodegradable materials in healthcare promises reduced plastic pollution, but their production, adoption, and long‐term impacts remain complex. Integrating lifecycle insights with global policy coordination is essential for meaningful environmental gains. Abstract The COVID‐19 pandemic sharply increased medical waste, intensifying concerns

Belief merging within fragments of propositional logic

open access: yes, 2014
Recently, belief change within the framework of fragments of propositional logic has gained increasing attention. Previous works focused on belief contraction and belief revision on the Horn fragment.

A Modular and Customizable CRISPR/Cas Toolkit for Epigenome Editing of Cis‐regulatory Modules

open access: yesAdvanced Science, EarlyView.
Epigenome editing surpasses genome editing in gene regulation. Modular epigenome editing frameworks are developed to interrogate cis‐regulome, enabling tunable reprogramming of cis‐elements, uncovering their epigenetic responsiveness and cross‐species portability.

Nonalcoholic Fatty Liver Disease Exacerbates the Advancement of Renal Fibrosis by Modulating Renal CCR2+PIRB+ Macrophages Through the ANGPTL8/PIRB/ALOX5AP Axis

open access: yesAdvanced Science, EarlyView.
The ANGPTL8/PIRB/ALOX5AP axis mediates liver‐kidney crosstalk. Hepatocytes secrete ANGPTL8, which binds to CCR2+PIRB+ macrophages in the kidneys, affecting the expression of ALOX5AP and enhancing the activation of these macrophages. Activated cells produce TGF‐β, IL‐6, and IL‐23, driving Th17 activation and promote the formation of myofibroblasts ...

Complexity of the Two-Variable Fragment with (Binary-Coded) Counting Quantifiers

open access: yes, 2004
We show that the satisfiability and finite satisfiability problems for the two-variable fragment of first-order logic with counting quantifiers are both in NEXPTIME, even when counting quantifiers are coded succinctly.Comment: 24 pages, 1 pstex_t ...

Geometrically Encoded Positioning of Introns, Intergenic Segments, and Exons in the Human Genome

open access: yesAdvanced Science, EarlyView.
This study introduces a new hypothesis: exons, introns, and intergenic segments are non‐random projections of the functional layers of 3D structure of chromatin packing domains. Evidence is presented that this “geometric code” may encode volumetric structure, reconciling epigenetic patterns, correlates with oncogenic mutations, acting as a potential ...
