Inosine‐Triphosphate‐Pyrophosphatase Activity as a Potential Predictor of Methotrexate Remission in Juvenile Idiopathic Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Methotrexate (MTX) is the first‐line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients do not respond to it. Low inosine triphosphate pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated the role and underlying mechanisms of ITPA in vitro. Methods ITPA enzymatic activity

Star-Critical Weakened Ramsey Numbers

Theory and Applications of Graphs
The weakened Ramsey number $r^{s,t}(G)$ is defined to be the least $p\in \mathbb{N}$ such that every $t$-coloring of the edges of the complete graph $K_p$ contains a subgraph isomorphic to $G$ that is spanned by edges that use at most $s$ colors ($1\le s\

Optimization of Operation Parameters in a Cesium Atomic Fountain Clock Using Monte Carlo Method

IEEE Access, 2021
Number of detected atoms and contrast of Ramsey fringe are critical operation parameters in an atomic fountain clock. To optimize these operation parameters, a Monte Carlo method is utilized to simulate the evolution of the atomic cloud. It is found that

Sustainable Innovation and Impact on Triple Bottom Line Performance: Are Innovation Types Simple Mediators?

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the way sustainable innovation, conceptualized as a second‐order construct integrating sustainable orientation and innovation culture, impacts triple bottom line (TBL) performance. It also examines the mediating roles of product, process, organizational, and marketing innovations.

A note on the Ramsey numbers for theta graphs versus the wheel of order 5

AKCE International Journal of Graphs and Combinatorics, 2018
The study of exact values and bounds on the Ramsey numbers of graphs forms an important family of problems in the extremal graph theory. For a set of graphs S and a graph F , the Ramsey number R (S , F) is the smallest positive integer r such that for ...

Digital Orientation and Green Practices in Chilean SMEs: Innovation as the Pathway to Competitive Performance

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how digital strategic orientation (DSO) and environmental practices (EP) interact to shape innovation and performance among Chilean SMEs. Using survey data from 271 firms (February–May 2022), we estimate a generalized structured component analysis (GSCA) model that accommodates a nonrecursive relationship between DSO and EP.

Anti-Ramsey numbers for disjoint copies of graphs [PDF]

Opuscula Mathematica, 2017
A subgraph of an edge-colored graph is called rainbow if all of its edges have different colors. For a graph \(G\) and a positive integer \(n\), the anti-Ramsey number \(ar(n,G)\) is the maximum number of colors in an edge-coloring of \(K_n\) with no ...

Net‐Zero Transition and Its Impact on Firms' Energy Efficiency and Economic Growth Within the Framework of Sustainable Development Goals: A Systematic Literature Review and Bibliometric Analysis

Business Strategy and the Environment, EarlyView.
ABSTRACT The transition to net zero (NZ) faces challenges such as uneven institutional readiness, fragmented policy frameworks and rising energy demands from population growth, economic expansion and artificial intelligence (AI). These obstacles are intensified by technological, financial and regulatory uncertainties that impede coordinated efforts ...
