Sampling rate-corrected analysis of irregularly sampled time series
(Amer Physical Soc, 2022)The analysis of irregularly sampled time series remains a challenging task requiring methods that account for continuous and abrupt changes of sampling resolution without introducing additional biases. The edit distance ... -
Reconstructing Network Dynamics of Coupled Discrete Chaotic Units from Data
(Amer Physical Soc, 2023)Reconstructing network dynamics from data is crucial for predicting the changes in the dynamics of complex systems such as neuron networks; however, previous research has shown that the reconstruction is possible under ... -
Nematic ordering in the Heisenberg spin-glass system in three dimensions
(Amer Physical Soc, 2023)Nematic ordering, where the spins globally align along a spontaneously chosen axis irrespective of direction, occurs in spin-glass systems of classical Heisenberg spins in d = 3. In this system where the nearest-neighbor ... -
Merged Potts-clock model: Algebraic and conventional multistructured multicritical orderings in two and three dimensions
(Amer Physical Soc, 2023)A spin system is studied with simultaneous permutation-symmetric Potts and spin-rotation-symmetric clock interactions in spatial dimensions d = 2 and 3. The global phase diagram is calculated from the renormalization-group ... -
First-order to second-order phase transition changeover and latent heats of q-state Potts models in d=2,3 from a simple Migdal-Kadanoff adaptation
(Amer Physical Soc, 2022)The changeover from first-order to second-order phase transitions in q-state Potts models is obtained at q(c) = 2 in spatial dimension d = 3 and essentially at q(c) = 4 in d = 2, using a physically intuited simple adaptation ... -
Performance Analysis of Saccades for Primary and Confirmatory Target Selection
(Assoc Computing Machinery, 2022)In eye-gaze-based selection, dwell suffers from several issues, e.g., the Midas Touch problem. Here we investigate saccade-based selection techniques as an alternative to dwell. First, we designed a novel user interface ... -
Mechanical Properties of Cement Mortars Incorporating Zero-Valent Iron Nanoparticles
(Asce-Amer Soc Civil Engineers, 2022)In this study, the effects of zero-valent iron (ZVI) nanoparticles (NPs) on the mechanical performance of cementitious composites were investigated. For this purpose, the use of a novel nanomaterial containing ZVI NPs ... -
The effects of prolactin on the immune system, its relationship with the severity of COVID-19, and its potential immunomodulatory therapeutic effect
(Academic Press Ltd- Elsevier Science Ltd, 2023)Prolactin (PRL) is an endocrine hormone secreted by the anterior pituitary gland that has a variety of physiological effects, including milk production, immune system regulation, and anti-inflammatory effects. Elevated ... -
Drıvers of Employee Dis/Satisfaction: A Comparison of Tourism and Sports Industries
(Akdeniz Univ, Tourism Fac, 2023)This study aims to identify the common and distinct factors affecting the dis/satisfaction of employees in two different industries, namely tourism and sports, and develop a model. The study was carried out using the ... -
Controlled CVD growth of ultrathin Mo2C (MXene) flakes
(Aip Publishing, 2022)MXenes combine distinctive properties, including high electrical conductivity, high thermal conductivity, and efficient absorption of electromagnetic waves, which allow them to be utilized in various applications such as ... -
A it-Electron Rich Cage via the Friedel-Crafts Reaction
(Amer Chemical Soc, 2022)A prism-shaped cage was obtained via the Friedel-Crafts reaction in a 2:3 mixture of trisfuryl and bis-isopropenyl precursors, in a remarkable yield of 40% considering six C-C bonds formed in a one-pot manner. The cage ... -
Invariant manifolds of homoclinic orbits and the dynamical consequences of a super-homoclinic: A case study in R4 with Z2-symmetry and integral of motion
(Academic Press Inc Elsevier Science, 2022)We consider a Z(2)-equivariant flow in R-4 with an integral of motion and a hyperbolic equilibrium with a transverse homoclinic orbit Gamma. We provide criteria for the existence of stable and unstable invariant manifolds ... -
Network structural origin of instabilities in large complex systems
(Amer Assoc Advancement Science, 2022)A central issue in the study of large complex network systems, such as power grids, financial networks, and ecological systems, is to understand their response to dynamical perturbations. Recent studies recognize that many ... -
