Two Extremal Problems in Graph Theory

open access: yes, 1998
We consider the following two problems. (1) Let t and n be positive integers with n # t # 2. Determine the maximum number of edges of a graph of order n that contains neither K t nor K t,t as a subgraph.

Advancing Environmental Sustainability: The Role of Artificial Intelligence in Monitoring, Predicting, and Controlling Sulfur Dioxide Emissions

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Air pollution from sulfur dioxide (SO2) emissions poses significant threats to environmental sustainability, public health, and climate change efforts. Despite advances in monitoring and regulatory frameworks, traditional methods often fall short in accuracy, scalability, and efficiency.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Neuromuscular Electric Stimulation Improves Early Isometric Knee Strength After Anterior Cruciate Ligament Reconstruction and Repair: A Meta‐analysis of Randomized Controlled Trials

open access: yesArthroscopy, EarlyView.
Purpose To assess the effectiveness of neuromuscular electrical stimulation (NMES) on quadriceps strength and knee function after anterior cruciate ligament surgery. Methods A comprehensive search of PubMed, Ovid MEDLINE, and Embase from inception until February 2025 was conducted.

Designing and evaluating a neuroanatomy learning experience using multiple external representations

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Neuroanatomy is challenging, requiring multiple external representations (MER) for comprehension. While studies have examined individual representations of neuroanatomy, a gap remains in understanding how students link across MER, especially between technology‐generated representations with everyday experiences.

Single‐subject designs in character education: Methods for rigorous, contextual, and practitioner‐led research

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Character education research is often constrained by blunt methodological tools. Surveys capture breadth without depth; case studies offer richness but lack replicability; and randomised controlled trials (RCTs), though indispensable at the policy level, are costly, disruptive and ill‐suited to everyday practice with individual pupils.

Problems in Chemical Graph Theory Related to the Merrifield-Simmons and Hosoya Topological Indices [PDF]

open access: yes
In some sense, chemical graph theory applies graph theory to various physical sciences. This interdisciplinary field has significant applications to structure property relationships, as well as mathematical modeling.

Accelerating green heterocyclic synthesis: Convergence of AI, automation, and sustainable chemistry

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Green heterocyclic synthesis and data‐driven tools such as AI, high‐throughput experimentation, continuous flow, and self‐driving laboratories have developed largely in parallel. This review connects them and asks how green metrics such as E‐factor and PMI might serve as explicit optimization targets rather than post‐hoc measures, toward sustainable ...

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Some Extremal And Structural Problems In Graph Theory [PDF]

open access: yes, 2016
This work considers three main topics. In Chapter 2, we deal with König-Egerváry graphs. We will give two new characterizations of König-Egerváry graphs as well as prove a related lower bound for the independence number of a graph. In Chapter 3, we study
