Ultrathin optical platform including two-dimensional materials and metasurfaces have emerged as potential candidates for novel nanophotonic applications. In this dissertation, I will present the possibility to achieve full active control of the electromagnetic waves with the platform in the flatland. We could achieve the amplitude control, which will be useful...
The use of polymeric membranes have become ubiquitous in our daily lives. From simple chip bags to million-dollar cockpits, these membranes find diverse applications in packaging, protective coating, electronic device, gas and liquid separation, and medicine. The 2-dimentional geometry of the membranes offered unique mechanical and interfacial properties that often...
This dissertation analyzes archival materials to examine the relationship between reproductive governance in India and the political and scientific dynamics of the Cold War. In 1952, India became the first country to institute anti-natalist population control as a national policy goal, concentrating its efforts on female sterilization and the building...
Gene regulatory networks contain multiple components including microRNAs (miRNAs) that coordinate regulation of genes to produce higher level cell functions. miRNAs are small non-coding RNA molecules that modulate gene expression post-transcriptionally by binding to short target motifs on mRNA transcripts to down-regulate target genes. Because miRNA regulation of genes is...
According to contemporary estimates, the 1933 Soviet famine killed six to eight million people, more than two million of them in Ukraine. This dissertation studies causes and consequences of this famine. ', 'Chapter one evaluates the causes of the 1933 famine offered by historians in Ukrainian context. Three main explanations...
Parents play a crucial role in shaping the contexts within which young children develop, particularly in the early years of a childs life (Bornstein, 2002; Brooks-Gunn & Markman, 2005; Maccoby & Martin, 1983). Parenting is also one of the key pathways through which socioeconomic factors, such as maternal education, may...
Raytracing is a long-established means to simulate physically accurate light propagation. Increasing availability and power of highly-parallel computing, such as cloud-based clusters and dedicated graphics hardware, means that rendering algorithms can produce high resolution output very quickly. This means raytracing can now be used as a forward model in optimization...
Maxwell equations are behind an incredible number of physical phenomena, explaining the behavior of light, electricity and magnetism, from Gamma rays to ultra-low frequency radio-waves. Since their inception in 1861, many approximations have been derived, many devices have been modelled and fabricated to manipulate the electromagnetic fields, and more recently...
Many democratic theorists suggest that harmonious relationship between groups are critical for democracy; however, far less is known about how everyday experiences promote or impede such intergroup harmony. In this dissertation, I explore a common, but overlooked, form of intergroup contact casual, brief experiences with outgroup strangers. I propose a...
Research shows that psychometrically-assessed spatial abilities (e.g., spatial visualization and spatial orientation) can be improved through training, and that some training yields improvements that are transferable to novel contexts and tasks (Uttal et al., 2013). While the training of these spatial abilities may be valuable for some forms of STEM...
