In 1948 Dr. Phyllis Freier and his team discovered the relativistic heavy ions component of the primary cosmic rays. A new field in Nuclear and Particle Physics became. In August 1970, the first heavy ions beam was used at the JINR Dubna to evidence the cumulative negative pions production in d-C collisions at 5 A GeV, using a linear accelerator and the Synchrophasotron U-10. Members of the...
The Albanian National Radioactive Waste Storage Facility (NRWSF) is operated by the Institute of Applied Nuclear Physics (IANP) in accordance with internationally acceptance criteria, and is situated within IANP territory. This facility consists of two main parts: a] operational area; b] interim storage facility (area). Apart from office and sanitary space the building contains the following...
In this paper, we analyzed the environmental and economic impact of implementing a hybrid nuclear-renewable energy system in Romania, in order to support national decarbonization goals and contribute to the global energy transition. Using Romanian-specific generation data and energy supply/demand models we simulated a nuclear- solar/wind system. The simulations were conducted using the...
This paper explores the integration of symmetry principles into digital twin models for complex mechatronic systems, highlighting their potential to enhance modeling efficiency, anomaly detection, and system scalability. By leveraging structural and functional symmetries, the proposed approach supports modular system design, reduces computational overhead, and improves predictive maintenance...
Understanding how complex biological systems behave over time is essential for predicting their future states, especially in diseases like Alzheimer’s disease. Mathematical modeling of such systems offers a valuable approach to exploring not only the theoretical aspects of network behavior but also their biological and medical implications. This study investigates how reducing the complexity...
Field programmable gate arrays (FPGA) are reconfigurable and serve as prototyping platforms for application-specific integrated circuits (ASIC). FPGA are composed of configurable logic blocks and programmable interconnects and allow rapid testing of digital designs. Many challenges in medical field, in agriculture and in security are solved by the implementation of artificial intelligence...

Unstained brightfield images pose a significant challenge for image analysis. U-Net architectures are a family of fully convolutional neural network which are used for image...
We demonstrate how the hypothetical X17 boson could influence the muon g−2 anomaly and the Lamb shift. Furthermore, by considering kinetic mixing between this new boson and the U(1)Y gauge field, we establish a possible contribution of the X17 to the W boson mass
This study presents basic aspects of discrete asymmetrical pulses generated by using delay operator applied on certain dynamical system. It is shown that the asymmetry of position for significant values inside the pulse time interval can be modelled using a binomial written as {(a+b)}^n, with a≠b and a+b=1.
This binomial model proves useful when pulses become shorter each time when they pass...
The integration of renewable energy sources into isolated power systems presents significant challenges related to voltage stability and power quality. This study focuses on modeling a reactive power compensation system to stabilize a solar-powered grid in the isolated region of Crișan, Tulcea County, within the Danube Delta. Two simulation models were developed using MATLAB/Simulink: one...
Microscopy is an important field that has seen significant improvements over the last decades to overcome unique inherent limitations. Some times the physical limitations could be overcome by using computational imaging. Fourier Ptychography is a powerful computational imaging technique that overcomes the resolution limitations of traditional microscopy by combining multiple low-resolution...
Most radiopharmaceuticals are used for the purpose of
medical diagnosis. These radiopharmaceuticals contain
small amount of the active substances with a
radionuclide attached to them to allow scintigraphic
imaging or measurement of biodistribution. Radiation is
a general property of all radiopharmaceuticals, which
when administered give the patient an imminent
radiation dose. Quality...
We present a novel neutron interferometry scheme designed to probe the potential existence of mirror neutrons, which have been proposed as viable dark matter candidates. Our theoretical analysis shows that, if mirror neutrons exist, ordinary neutrons would acquire a detectable geometric phase due to their mixing with these mirror partners
Within the framework of quantum field theory, we investigate neutrino oscillations in the presence of a torsion background. Adopting the Einstein–Cartan theory, we analyze both the cases of constant torsion and torsion that varies linearly with time. We derive new neutrino oscillation formulae that depend on the spin orientation and obtain an expression for CP asymmetry.
Starting from the quantum model of the hydrogen atom, we calculate and tabulate the peaks of Humphreys α-multiplet in fine-structure approximation (fs-approximation) [1,2]. We determine the spectral line peaks of this multiplet using a new MaximumLocalisation-spectral-Model which is based on several spectroscopic and statistical hypotheses [2-4]. By statistical analysis of the NIST and...
