Instance segmentation, the classification and localization of objects in an image, is a problem in cellular biophysics due to the physiological relevance of cell morphology. Particularly, cancer cells migrate in tissue space by changing their body shape similarly to how humans extend their limbs to swim through water. Monitoring such...
The study of carrier transport in light-emitting diode (LED) has been researched extensively in the past. However, most studies were implementing voltages above the turn-on voltage of the LED. Research on LEDs well below the turn-on voltage threshold is comparatively scarce for good reasons. When the supply voltage is below...
Nuclear fusion has the potential to meet the energy needs of our civilization for centuries to come and does not produce harmful greenhouse gasses or produce long-lasting radioactive waste. A fusion reaction can be readily demonstrated in a confinement scheme known as inertial electrostatic confinement (IEC) fusion. In this work,...
The standard interpretation of quantum mechanics (known as the Copenhagen interpretation) divides the world into quantum phenomena and classical observers that perform measurements upon the phenomena. This provides a quite functional framework for calculating probabilities of measurement outcomes, but it lacks the generality necessary for such things as retrodiction, and...
Thermodynamic properties of systems are often investigated computationally. Traditionally, thermal physics simulations are limited by their very small energy ranges and slow convergence. Broad histogram algorithms are a class of Monte Carlo algorithms that can explore an entire energy (and temperature) range in one thermal physics simulation: potentially saving months...
Silicon based quantum computing is an attractive approach to large-scale quantum computation due to the significant success of the modern semiconductor fabrication industry. Despite many advances in silicon quantum computing since its inception in 1998, there remains no software for efficiently designing candidate silicon quantum computing devices. Such a development...
Surface waves play a vital role in air-sea interactions, and being able to easily measure them in-situ validates and improves predictive models. Here, we diagnose surface wave properties in the Bay of Bengal using modified vertical SOLO II profiling floats, which are regularly used as part of the Argo ocean...
Gamma ray bursts (GRBs) are short, intense pulses of gamma rays that emit radiation in a narrow beam. Unless the beam is oriented towards the observer, it is often difficult to resolve the bursts against the diffuse gamma ray background (DGRB). The DGRB is a measured source of gamma rays...
This research investigates the electronic properties of a fungi-derived pigment, xylindein
as a novel sustainable material for organic electronics. Xylindein molecules were characterized in solution and in film. Absorption spectra and (photo)luminescence spectra were
taken at various excitation wavelengths. Xylindein’s molecular properties were computed
with the Gaussian 09 software suite....
High field time-domain terahertz spectroscopy (TDS) is used to determine the time dependent transmission and the time-delay and optical-power dependent conductivity of a wafer of gallium arsenide (GaAs). Gallium arsenide is a direct band-gap semiconductor and has potential as a computer processor component. Analysis of the transmission of terahertz (THz)...
