Neutrinos are the fundamental particles which has promising potent to unveil the mysteries of our universe. Besides their importance in understanding fundamental Physics, a new era of multimessenger astronomy with neutrinos is outspreading which is evident from the large scale neutrino detectors around the world sensitive from meV to PeV energy scales. In this presentation, we discuss the...
The cosmic web of the Universe consists of a patchwork of dense clusters and empty voids, with strands of filamentary networks connecting and feeding these central clusters. Observations have demonstrated that these clusters harbor a lower fraction of star-forming galaxies relative to the isolated galaxies of the field, but astronomers have largely “washed out” filaments in their descriptions...
Brief presentation of methods to improving your Monte Carlo programming.
To be covered:
0.) "Do you need that precision?"
1.) Sorting assisted random sampling
2.) Fit assisted random sampling
3.) A derivation of an analytic form of random sampling, its benefits
4.) Fits for verification
5.) Statistical measures for verification
With the Sun as the Earth’s main source of energy and heat, it is critical to understand how and why it varies. The Sun’s irradiance changes over its 11-year solar cycle driven by variabilities in the magnetic field. The primary objective of this project was to create a machine learning model that predicts the total solar irradiance (TSI) and then analyze the contributions of each feature...
Breast cancer prognosis and treatment is generally dependent on a patient’s molecular subtype, those being luminal A, luminal B, HER2-enriched, or basal-like (triple-negative). Current subtyping tests rely on fluorescence-based reporting with barcoded probes, but have low sampling efficiency (>100 ng RNA) and as such, may not accommodate liquid biopsy samples. The goal of this project is to...
One of the main cancer treatments is radiotherapy
(radiation therapy). In order to reduce the risk of
radiation-related problems, it is important to pro-
vide the tumor with the specified radiation dose
while limiting the unavoidable dose to the nearby
healthy organs. The optimization of radiotherapy
treatment plans looks for machine settings that
produce desirable treatment schemes...
Discussion of cooling equipment built here in the High Energy Physics (HEP) lab to cool particle detectors for experimentation. The cooling is necessary to reduce thermal noise, an ever present antagonist to a good room-temp experiment.
We investigated two organic molecules, PTCDI and PTCDA, which stack by making different molecular patterns on the MoS2 surface. Using photoemission spectroscopy, we observed a HOMO and LUMO splitting near the interface in PTCDI/MoS2 but not in PTCDA/MoS2. Density functional theory calculation showed that the splitting of the energy levels originates from the difference in the molecular...
This study introduces a method to improve the decision-making process of reinforcement learning agents via quantum information technology. In this approach, states |├ s⟩ of the system are replaced by quantum states (eigenfunctions) of the system |├ ψ⟩, in which a system can be in a superposition of states, and rewards of each step are calculated based on the calculated eigenvalues of the...
Active galactic nuclei (AGN) have different emission spectra depending on their physical characteristics. Using only one wavelength region to identify an AGN may miss sources with unique characteristics. In this work, we compare the multiwavelength properties of X-ray and mid-infrared (MIR) selected AGN in the COSMOS field. Our X-ray-selected AGN sample includes all sources with a $0.5-10$ keV...
Memristor fabrication techniques have been able to create memristors in the ultrathin regime (sub-2 nm). The fundamental paradox of memristors at this scale is that the number of defects in the active layer must be minimized to prevent undesirable leakage current but needs to include a sufficient and well distributed quantity of oxygen vacancies to promote conductive filament formation....
