<b>Analysis of State Changes in English Causative Constructions: Insights from Construction Grammar</b>

This research aims to explore how English causative constructions convey changes in state, using the frameworks of Construction Grammar and Radical Construction Grammar. The 310 English language samples were selected based on their relevance to illustrating transitions caused by internal or external factors, sourced from reliable texts, diverse contexts, varied grammatical constructions, and common usage patterns. Through a thorough examination of syntax and semantics, the study aims to illustrate how causative constructions effectively capture dynamic processes and cognitive perceptions. Emphasis is placed on the roles of the agent and patient, with the analysis seeking to uncover how these structures deal with causality and, crucially, changes in state. The findings show that causative structures in English mainly depict physical changes, although there is still a significant representation of emotional and mental changes. This analysis reveals the universal and language-specific aspects of causative constructions and provides insights into how they are used in everyday conversations and cognitive activities.

A Fault-Tolerant Model for Performance Optimization of a Fog Computing System

In a distributed heterogeneous fog environment, fog nodes may change their state at any time. Their reliability changes accordingly. A dynamic analysis of state changes can help one detect fault-tolerant fog nodes, which is conducive to promoting the reliability of fog services. This article proposes a fault-tolerant model based on a Markov chain for a fog system’s performance optimization. The real-time reliability of fog nodes is analyzed by using dynamic distributed parameters. Thus, the state transition process of fog nodes is modeled with a continuous-time Markov chain. The steady-state probability of a fog system is analyzed. Then, a fault-tolerant strategy and its algorithms are designed to select nodes with the minimum cost based on their steady-state probabilities. The proposed method can predict the number of faulty ones of a fog system via the steady-state probability. An intelligent optimization method called simulated annealing (ISA) is designed and used to select the most appropriate fog nodes to substitute faulty ones. The experimental results show that the method is feasible and effective for selecting the right fault-tolerant nodes according to different performance requirements. ISA can well outperform such methods as random selection, discrete differential evolution, and simulated annealing in terms of cost and time.

Analysis of Changes in State of Health Induced by Low-Dose Ionizing Radiation

Analysis of Changes in State of Health Induced by Low-Dose Ionizing Radiation

Historical and biomechanical analysis of integration and dissociation in molluscan feeding, with special emphasis on the true limpets (Patellogastropoda: Gastropoda).

Modifications of the molluscan feeding apparatus have long been recognized as a crucial feature in molluscan diversification, related to the important process of gathering energy from the environment. An ecologically and evolutionarily significant dichotomy in molluscan feeding kinematics is whether radular teeth flex laterally (flexoglossate) or do not (stereoglossate). In this study, we use a combination of phylogenetic inference and biomechanical modeling to understand the transformational and causal basis for flexure or lack thereof. We also determine whether structural subsystems making up the feeding system are structurally, functionally, and evolutionarily integrated or dissociated. Regarding evolutionary dissociation, statistical analysis of state changes revealed by the phylogenetic analysis shows that radular and cartilage subsystems evolved independently. Regarding kinematics, the phylogenetic analysis shows that flexure arose at the base of the Mollusca and lack of flexure is a derived condition in one gastropod clade, the Patellogastropoda. Significantly, radular morphology shows no change at the node where kinematics become stereoglossate. However, acquisition of stereoglossy in the Patellogastropoda is correlated with the structural dissociation of the subradular membrane and underlying cartilages. Correlation is not causality, so we present a biomechanical model explaining the structural conditions necessary for the plesiomorphic kinematic state (flexoglossy). Our model suggests that plesiomorphically the radular teeth must flex laterally as they pass over the bending plane as a result of the mechanical restrictions in the flexible but inelastic subradular membrane and close association between subradular membrane and cartilages. Relating this model to the specific character states of the clades, we conclude that lack of flexure in patellogastropods is caused by the dissociation of the subradular membrane and cartilage supports.

Distinctions in Agonist and Antagonist Specificity Conferred by Anionic Residues of the Nicotinic Acetylcholine Receptor

Two anionic residues in the nicotinic acetylcholine receptor, Asp-152 in the alpha-subunit and Asp-174 in the gamma-subunit or the corresponding Asp-180 in the delta-subunit, are presumed to reside near the two agonist binding sites at the alphagamma and alphadelta subunit interfaces of the receptor and have been implicated in electrostatic attraction of cationic ligands. Through site-directed mutagenesis and analysis of state changes in the receptor elicited by agonists, we have distinguished the roles of anionic residues in conferring ligand specificity and ligand-induced state changes. alphaAsp-152 affects agonist and antagonist affinity similarly, whereas gammaAsp-174 and deltaAsp-180 primarily affect agonist affinity. Combining charge neutralization on the alpha subunit with that on the gamma and delta subunits shows an additivity in free energy changes for carbamylcholine and d-tubocurarine, suggesting independent contributions of these residues to stabilizing the bound ligands. Since both aromatic and anionic residues stabilize cationic ligands, we substituted tyrosines (Y) for the aspartyl residues. While the substitution, alphaD152Y, reduced the affinities for agonists and antagonists, the gammaD174Y/deltaD180Y mutations reduced the affinity for agonist binding, but surprisingly enhanced the affinity for d-tubocurarine. To ascertain whether selective changes in agonist binding stem from the capacity of agonists to form the desensitized state of the receptor, carbamylcholine binding was measured in the presence of an allosteric inhibitor, proadifen. Mutant nAChRs carrying alphaD152Q or gammaD174N/deltaD180N show similar reductions in dissociation constants for the desensitized compared with activable receptor state and a similar proadifen concentration dependence. Hence, these mutations influence ligand recognition rather than the capacity of the receptor to desensitize. By contrast, the alphaD200Q mutation diminishes the ratio of dissociation constants for two states and requires higher proadifen concentrations to induce desensitization. Thus, the contributions of alphaAsp-152, gamma/deltaAsp-174/180, and alphaAsp-200 in stabilizing ligand binding can be distinguished by the interactions between agonists and allosteric inhibitors.

Epigenetic inheritance of transcriptional states in S. cerevisiae

SIR1, one of several genes required for repression of yeast silent mating type loci, has a unique role in repression of the HMLα locus. Single-cell assays revealed that cells with mutant alleles of SIR1, including presumptive null alleles, existed as populations of genetically identical cells whose members were in one of two different regulatory states. A minority of cells had a repressed HMLα locus whereas the majority had a derepressed HMLα locus. The two states were mitotically stable, although rare changes in state were observed during mitotic growth, possibly reflecting heritable changes to the HMLα locus at or before replication. Analysis of changes in state suggests that SIR1 protein has a role in the establishment but not the maintenance of repression of silent mating type genes, whereas SIR2, SIR3, and SIR4 are required for maintenance.
