A Practical Guide to Studying Magnetic Alignment of Free‐Living Animals: Lessons From Leopards

Ethology, EarlyView.
We show that spatial autocorrelation in circular data can be detected and provide guidelines how to avoid such issues in magnetic alignment field studies. ABSTRACT Spontaneous magnetic alignment describes the tendency of animals to preferentially orient their major body axis in a non‐random alignment relative to the magnetic field.

Fatigue Crack Modeling of Railheads Using a Nonlinear Cohesive Zone Model

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Subsurface fatigue crack growth within railheads can be deleterious leading to catastrophic failures in rails. This study aims to model the fatigue crack growth originating at the subsurface level within railheads. Towards that end, a finite element modeling approach is utilized wherein complex crack growth is explicitly modeled using a ...

Exact and metaheuristic approaches to minimizing makespan in parallel machine scheduling with conflicting jobs

International Transactions in Operational Research, EarlyView.
Abstract We address the scheduling conflicting jobs on parallel identical machines problem with makespan minimization, a classical and computationally challenging variant of parallel machine scheduling. We develop and evaluate three distinct solution methodologies: a novel constraint programming (CP) formulation, and two metaheuristics: a multi ...

Safety at Level Crossings: A Comparative Analysis of the Railways of Republika Srpska and Croatian Railways

At level crossings (LCs), 24% of all significant railway accidents occur. Safety at LCs is influenced by various factors, including the behavior of road traffic participants (drivers, cyclists, pedestrians), the type of LC protection, and weather conditions.

Common Equity Investors’ Assessments of the Dilution and Solvency Effects of Preferred Stock Instruments

Journal of Business Finance &Accounting, EarlyView.
ABSTRACT Generally accepted accounting principles (GAAP) requires dichotomous classification of financial claims as liabilities or equity. Classifying claims is challenging when instruments have attributes of both liabilities and equity (i.e., hybrid instruments).
