Decidability problems in grammar systems [PDF]

open access: yes, 1999
Most of the basic decision problems concerning derivations in cooperating distributed grammar systems have so far been open, possibly because of the lack of unifying methods and techniques. In this paper such a unifying device is proposed. It is called a

Polarization Dynamics in Ferroelectrics: Insights Enabled by Machine Learning Molecular Dynamics

open access: yesAdvanced Science, EarlyView.
Machine learning molecular dynamics is presented as a route to capture polarization switching, domain wall kinetics, topological polar textures, and polar mechanical coupling beyond the limits of conventional atomistic methods. This Perspective surveys recent progress and identifies key methodological directions, including long‐range electrostatics ...

VARIANTS OF COMPETENCE-BASED DERIVATIONS IN CD GRAMMAR SYSTEMS [PDF]

open access: yes, 2010
In this paper we introduce and study some new cooperation protocols for cooperating distributed (CD) grammar systems. These derivation modes depend on the number of different nonterminals present in the sentential form obtained when a component finished

Self‐Sustaining Lactate Depletion Nanoplatform Remodels Tumor Microenvironment and Augments Synergistic Photodynamic/Photothermal/Chemodynamic/Starvation Therapy for Eradication of Colon Cancer

open access: yesAdvanced Science, EarlyView.
The HILA nanoplatform integrates HMnO2, LOX, and ICG to orchestrate multimodal therapy (starvation, chemodynamic, photodynamic, and photothermal) for achieving efficient colon cancer eradication. The established HMnO2‐LOX catalytic cycle continuously consumes lactate, acidifys microenvironment, relieves hypoxia, and generats reactive oxygen species ...

Cooperating Distributed Splicing Systems [PDF]

open access: yes, 1997
We introduce a new class of cooperating distributed H systems which consist of a given set of splicing systems (sets of splicing rules plus sets of axioms), similar in form to the cooperating distributed grammar systems.

Current Challenges of Transcription Compartmentalization Research

open access: yesAdvanced Science, EarlyView.
Transcription factors, coactivators, and RNA polymerase II assemble into transcription compartments ranging from small, defined complexes to liquid‐like condensates. This review unifies these seemingly competing descriptions along a single continuum and asks what these compartments have been shown to do, and what they have not, revealing that the most ...

Redistributive land reforms, agricultural productivity, and structural change: New cross‐national evidence

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

Array P Systems and t−Communication [PDF]

open access: yes, 2009
The two areas of grammar systems and P systems, which have provided interesting computational models in the study of formal string language theory have been in the recent past\ud effectively linked in [4] by incorporating into P systems, a communication ...

Nanostructured Deep Eutectic Systems in Healthcare: From Bioactive Solvents to Intelligent Biointerfaces, Wearables, and AI‐Driven Design

open access: yesAdvanced NanoBiomed Research, EarlyView.
Beyond the green solvent paradigm, this review redefines Deep Eutectic Systems (DES) as programmable supramolecular nanoassemblies. We survey their biomedical convergence: stabilizing thermolabile mRNA to enable cold chain‐free logistics, reshaping transdermal microneedle delivery, enabling long‐term wearables via eutectogels, and utilizing Generative ...

Past and Future of Sustainability Indicator Research in Agribusiness: A Bibliometric and Forecasting Analysis

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study offers a forward‐looking assessment of sustainability indicator research in agribusiness by integrating bibliometric mapping with ARIMA‐based forecasting. Analysing 403 Scopus‐indexed articles, bibliographic‐coupling analysis identifies three contemporary thematic domains: Techno‐Managerial Sustainability, Systemic and ...
