This research study introduces an innovative design concept named BriXSinO, which aims to generate high repetition rate THz and X-ray synchronized radiation pulses. The proposed BriXSinO system incorporates an Energy Recovery Linac (ERL) based on Superconducting cavities (SC), operating in Continuous Wave mode (CW), and remarkably sustaining MW-class beam power with only 100 kW active power...
Precise luminosity measurements is a crucial aspect of collider physics. Luminosity calibration at hadron colliders relies on the van-der-Meer scan method, where colliding particle beams are swept across each other and the reaction rates are recorded based on the separation distance between them. Initially, Gaussian distributions adequately described particle densities for luminosity...
Multilayered epithelial tissues, such as skin and gut, comprise major organs in humans. These tissues perform multiple functions, including serving as a barrier to mechanical insults, and pathogens. They are constantly self-renewing while balancing proliferation in the basal layer with a tightly controlled differentiation program in which cells move upward while undergoing stepwise...
The computation of electronic structure properties at the quantum level is a crucial aspect of modern physics research. However, conventional methods can be computationally demanding for larger, more complex systems. To address this issue, we present a hybrid Classical-Quantum computational procedure that uses the Variational Quantum Eigensolver (VQE) algorithm. By mapping the quantum system...
Hafnium (Z = 72) is an element that could be employed in plasma-facing materials in Tokamaks [1,2] and is also produced in neutron-induced transmutation of tungsten (Z = 74) and its alloys that will compose the divertors in these fusion reactors [3]. As a consequence, their sputtering may generate ionic impurities of all possible charge states in the deuterium-tritium plasma. These impurities...
The use of fiber Bragg grating (FBG) Optical sensors in the Internet of Things (IoT) has made a lot of research interest because of the potential applications, such as remote monitoring of transformer substation subsidence, intelligent power grid sensing, and mine safety monitoring [1]. Disaster prediction and forecasting in infrastructure building, on the other hand, necessitate the use of...
The Passive Gamma Emission Tomography (PGET) device was approved by the IAEA for spent nuclear fuel safeguards inspections at the end of 2017 resulting from the JNT 1510 project. It is based on a collimator, consisting of a linear array of narrow slits with a pitch of 4 mm, with a relatively small CZT (cadmium-zinc-telluride) gamma ray detector behind each slit [1,2]. The detectors have a good...
The Mu2e experiment at Fermilab searches for the neutrino-less conversion of a negative muon into an electron, with a distinctive signature of a mono-energetic electron with energy of 104.967 MeV. Mu2e aims to improve by four orders of magnitude with respect to the current best limit.
The calorimeter plays an important role to provide excellent particle identification capabilities and an...
Genius in Africa (GiA) is a platform that searches out and supports the best and most promising students residing in the rural areas of Africa. Our primary objective is to locate and assist rural geniuses and also support them towards achieving their goals. Rural geniuses in this context are both the reached (via technology) and the unreached talents across the continents that have mastered...
Citizens and Travelers II is a project that is aimed towards the collection and publishing of the stories of African scientists. We strongly believe that everyone has a story to tell either those with happy endings or unhappy ones. These stories, if shared, will, in turn, motivate, guide and correct others. We have read stories of how the western world has made an impact in science, we believe...
I will give an overview of the high performance storage used at the US-ATLAS Tier2 computing facility (SWT2-OU) at the University of Oklahoma (OU), and the plans to migrate from the current XRootD based storage to the large CEPH based solution developed at OU. Both XRootD and CEPH are free high performance parallel file systems that can be deployed on any commodity storage hardware. XRootD was...
This analysis presents the search for the Standard Model Higgs that decays to a pair of dark Higgs to an eight-lepton final state via four dark vector bosons. In this scenario, the SM Z boson can kinetically mix with the U (1)D gauge boson ZD while the dark Higgs S and the SM Higgs can exhibit mass mixing. Either of the Higgses can can be formed from gluon-gluon fusion and decay to the other...
Hidden sector or dark sector states appear in many extensions to the Standard Model, to provide a particle candidate for dark matter in universe or to explain astrophysical observations such the as positron excess observed in the cosmic radiation flux. A hidden or dark sector can be introduced with an additional U(1)d dark gauge symmetry. The presence of the dark sector could be experimentally...
A collider search for dark matter through dark photons based on a phenomenological study [1, 2] is presented. Where simulated samples with the ATLAS detector at the CERN LHC with a center-of-mass energy of 13 TeV are used. A dark photon is a hypothetical dark matter particle which may be detected through its kinetic mixing with the general photon. In which it couples weakly to electrically...
The cosmic web, a complex network of thin walls, elongated filaments, and dense clusters enclosing empty voids, provides a map of the universeโs dark matter density distribution. Dark matter halos are structures that form and grow due to the gravitational instability caused by initial density perturbations in the cosmic field, vary in their characteristics, such as mass and contained galaxies,...
In this talk, I will discuss aspects of microscopic degrees of freedom of gravity and the physical motivation of quantum gravity. While the generic states are quantum mechanical, our goal will be to understand a class of them that are coherent enough to admit classical descriptions in Einstein gravity. The existence of these state require topological structures in spacetime that follow from...
We study the response of a Bose-Einstein condensate (BEC) in a ฮด-kicked optical lattice ratchet potential with ฮด-kicked interactions, at quantum resonances. Solving the Gross-Pitaevskii Equation (GPE) and its associated Classical map, we found that our results strongly depend on the kicking strength K and the interaction parameter หg. A critical curve emerging from the (K, หg)-space,...
