Ensuring compliance with maximum residue limits (MRL) for pesticide residues in fresh produce is crucial for food safety. Traditional detection methods such as chromatography and mass spectrometry, while accurate, are often time-consuming, expensive, and require complex sample preparations. This study aimed to evaluate the effectiveness of combining Raman spectroscopy with deep learning...
The management of human diseases is transitioning from traditional methods toward personalized medicine, with thermal therapy—comprising clinical hyperthermia and therapeutic hypothermia—becoming a focal point of research. However, both therapies face challenges in clinical trials due to difficulties in monitoring temperature and delivering precise heat to targeted tissue areas. This thesis...
Space weather, defined as the variable conditions in space driven by the sun, significantly impacts the performance of both terrestrial and space-based technologies. To mitigate these adverse effects, it is essential to develop accurate storm-time space weather models. Since the sun is the primary driver of these models, solar indices like SSN and F10.7 are crucial for creating these models....
Geophysical method of exploration involving 2D Electrical Resistivity Tomography was employed to compare the resolution and sensitivity of different electrode configurations in order to delineate potential drill point for groundwater at Nsakye. The 2D Electrical resistivity tomography (ERT) using the Dipole-dipole, Wenner, Schlumberger electrode array configurations was deployed along...

The experimental data from various hadronic and heavy-ion collisions have been studied to investigate nuclear matter under extreme temperature and pressure. Under such conditions, the nuclear matter undergoes different phase transitions from the hadronic matter to the quark-gluon plasma (QGP) matter. Also, there are several experimental indicators that allow studying different regions of the...
The ATLAS detector is one of the two general-purpose detectors at the Large Hadron Collider (LHC) at CERN, designed to explore a wide range of physics, including the discovery of new particles, precision measurements of known particles, and searches for signs of new physics beyond the Standard Model. One of the essential parts of the ATLAS experiment is the trigger system, which manages large...
Brain tumor detection is a critical task in medical diagnostics, where early and accurate identification can significantly impact patient outcomes. This research focuses on the development and optimization of deep learning (DL) models to enhance the accuracy and efficiency of brain tumor detection from magnetic resonance imaging (MRI) scans. By leveraging Convolutional Neural Networks (CNNs),...
This study investigates the microdosimetry of Boron Neutron Capture Therapy (BNCT) using high-fidelity Monte Carlo simulations to quantify the energy deposition distributions from alpha and lithium-7 particles in cellular structures.
We employ Geant4 to model various physics lists and water representations, aiming to optimize the accuracy of BNCT simulations. Dosimetry and microdosimetry...
Cold-modified Alfven waves of multi-ion species propagating perpendicular to an ambient magnetic field have been investigated. We derive the linear dispersion relation for any number of species. In addition to the conduction current density, we consider the displacement current density. The derived dispersion relation suggests a magnetized plasma mode to propagate at the long-wavelength for...
The Zinc ferrite (ZnFe2O4) has significantly attracted many researchers due to their chemical and thermal stability [1] and their narrow band gap [2]. In this present research we successfully studied the influence of Graphene (Gra) doping on the physical properties of zinc ferrite thin films. The undoped and Gra-doped ZnFe2O4 nanofilms were grown onto glass substrates using spray pyrolysis...
This work is a theoretical study of a proposed novel system whose purpose is to convert solar radiation to electrical energy. The study proposed an electron chamber with trapped electrons inside it. The trapped electrons were then excited by photons of specific frequency. The excited electrons were allowed to escape the chamber across a circular boundary to an evacuated coil-shaped path. The...
In this paper, we obtain a solution of a static spherically symmetric charged black hole inspired by noncommutative geometry in the context of the regularized 4D-Einstein–Gauss–Bonnet theory in AdS space. The derived metric recovers the standard solutions’ limits. It tends to the commutative case solution found in [P. G. S. Fernandes, Phys. Lett. B 805, 135468 (2020)] at large distance r+θ→∞...
Testing the Swampland conjectures in the context of string theory on Calabi-Yau threefolds has led to interesting results,both mathematically and physically. We generalize results of fibration structure of Calabi-Yau fourfold with finite volume in infinite distances in the moduli space. By applying these results to compactifications of M-theory on K3xK3 we relate weak coupling and strong...
