Evolution of Cosmic Necklaces and Lattices
, 2010 Previously developed analytic models for the evolution of cosmic string and monopole networks are applied to networks of monopoles attached to two or more strings; the former case is usually known as cosmic necklaces.

Using Convolutional Neural Networks for the Classification of Suboptimal Chest Radiographs
Journal of Medical Radiation Sciences, EarlyView.This study evaluated DenseNet121 and YOLOv8 neural networks in detecting suboptimal chest x‐rays for quality control. Through training, validation, and testing, both AI models effectively classified chest X‐ray quality, highlighting the potential to provide radiographers with feedback to enhance image quality.

A combinatorial model for the free loop fibration
, 2018 We introduce the abstract notion of a closed necklical set in order to describe a functorial combinatorial model of the free loop fibration $\Omega Y\rightarrow \Lambda Y\rightarrow Y$ over the geometric realization $Y=|X|$ of a path connected simplicial

Uncovering the Complexity of Synucleinopathies: An Ongoing Tale Between Proteins and Lipids
Movement Disorders, EarlyView.Abstract Neurodegenerative diseases are pathological states characterized by progressive alterations in brain homeostasis during aging. Synucleinopathies, including Parkinson's disease and dementia with Lewy bodies, are defined neuropathologically by the accumulation of inclusions known as Lewy bodies and Lewy neurites.

Ultra high energy cosmic rays from cosmological relics
, 1998 Ultra High Energy Cosmic Rays (UHECR) can be a signal from very early (post-inflationary) Universe. At this cosmological epoch Topological Defects (TD) and long-lived suprheavy (SH) particles are expected to be naturally and effectively produced. Both of

Regulatory mechanisms of reproduction in locusts and grasshoppers
New Plant Protection, EarlyView.Regulatory networks composed of numerous coding and noncoding genes play crucial roles in the reproduction of locusts and grasshoppers. This review integrates mechanistic advances in reproductive regulation, highlighting environmentally adaptive pathways and providing prospective targets for eco‐friendly pesticides.

The role of derivative instruments in interest risks decrease [PDF]
Anali Ekonomskog fakulteta u Subotici, 2018 This paper looks at a specific side of market risk, called interest risk, and how banks can control the risk coming from certain interest positions, by using derivative instruments.

Numerical simulations of necklaces in SU(2) gauge-Higgs field theory [PDF]
, 2016 We perform the first numerical simulations of necklaces in a non-Abelian gauge theory. Necklaces are composite classical solutions which can be interpreted as monopoles trapped on strings, rather generic structures in a Grand Unified Theory.
