Employing Locally Finitely T-Transitive Binary Relations to Prove Coincidence Theorems for Nonlinear Contractions

Journal of Function Spaces, 2020
In this article, we prove some relation-theoretic results on coincidence and common fixed point for a nonlinear contraction employing a locally finitely T-transitive binary relation, where T stands for a self-mapping on the underlying metric space.

Relation-preserving generalized nonlinear contractions and related fixed point theorems

AIMS Mathematics, 2022
In this paper, we present some fixed point theorems for generalized nonlinear contractions involving a new pair of auxiliary functions in a metric space endowed with a locally finitely T-transitive binary relation.

Carbon‐Cutting Chess: Strategizing Resilient Low‐Carbon Investments for Supply Chains

Business Strategy and the Environment, EarlyView.
ABSTRACT This research presents a novel empirical and analytical method for strategizing low‐carbon investment strategies (LCIS) in supply chains, viewed through the lens of sustainable and resilient efficiency. The study develops a clear, actionable framework for identifying, evaluating, and implementing LCIS by using a mixed‐methods design.

Optimal pair of fixed points for a new class of noncyclic mappings under a $ (\varphi, \mathcal{R}^t) $-enriched contraction condition

Electronic Research Archive
In the present study, we commenced by presenting a new class of maps, termed noncyclic $ (\varphi, \mathcal{R}^t) $-enriched quasi-contractions within metric spaces equipped with a transitive relation $ \mathcal{R}^t $.

MS2DECIDE: Aggregating Multiannotated Tandem Mass Spectrometry Data with Decision Theory Enhances Natural Products Prioritization

Chemistry–Methods, EarlyView.
Tandem mass spectrum to decision (MS2DECIDE) leverages decision theory and expert knowledge to aggregate the outputs of three widely used annotation tools (GNPS, Sirius, and ISDB‐LOTUS) and compute a recommendation for targeting natural products with regard to their potential novelty.

Generalized Weak Contractions Involving a Pair of Auxiliary Functions via Locally Transitive Binary Relations and Applications to Boundary Value Problems

Mathematics
The intent of this paper was to investigate the fixed-point results under relation-theoretic generalized weak contractivity condition employing a pair of auxiliary functions ϕ and ψ verifying appropriate properties.

Teaching undergraduates to solve equivalence problems by using cover, copy, and compare: A translational study

Journal of Applied Behavior Analysis, EarlyView.
Abstract Cover, copy, and compare (CCC) is a study strategy in which students cover their notes, attempt to copy them, and then compare for accuracy. We evaluated whether CCC could be used to establish equivalence classes with undergraduate students.

Simple 3‐Designs of PSL ( 2 , 2 n ) With Block Size 13

Journal of Combinatorial Designs, EarlyView.
ABSTRACT This paper focuses on the investigation of simple 3‐ ( 2 n + 1 , 13 , λ ) designs admitting PSL ( 2 , 2 n ) as an automorphism group. Such designs arise from the orbits of 13‐element subsets under the action of PSL ( 2 , 2 n ) on the projective line X = GF ( 2 n ) ∪ { ∞ }, and any union of these orbits also forms a 3‐design.
