Ghanavati, Mandana (author), Young, Ian (author), Kirezci, Ebru (author), Ranasinghe, Roshanka (author), Duong, Trang Minh (author), Luijendijk, Arjen (author)A common inference in research studies of observed and projected changes in global ocean wave height and storm surge, is that such changes are potentially important for long-term coastal management. Despite numerous studies of the impacts of anthropogenic climate change on trends in global wind and waves, a clear link to impacts on sandy...journal article 2023

(author), Young, Abram (author), Walker, Christopher (author), Gao, J.R. (author)We have simulated and measured the beam properties of lens-antenna coupled hot electron bolometer mixers at a few supra-terahertz frequencies between 1.4 and 5.3 THz. The quasi-optical structures consist of an elliptical lens and a logarithmic spiral antenna. The model used for our simulations consists of a finite-element analysis to simulate...journal article 2023

(author)We report a high accuracy pointing technique for quasi-optical hot electron bolometer (HEB) mixers in focal-plane arrays designed to operate at 1.4, 1.9, and 4.7 THz. The high accuracy pointing is achieved by prealignment of a HEB chip to a lens, measuring the angular error of each mixer in an array assembly, and then realignment of the chip...journal article 2022

Meisch, Simon P. (author), Bremer, Scott (author), Young, M.T. (author), Funtowicz, Silvio O. (author)This paper explores the implications of assessing tacit knowledges of climatic change in extended peer communities, as applied in two European research projects on climate action. Post-normal science (PNS) proposes the extension of the peer community to co-produce better quality knowledge for decision-making on issues like climate change,...journal article 2022

Dahlgren, F.S. (author), Gershkoff, Zachary (author), Hogben, Leslie (author), Motlaghian, Sara (author), Young, Derek (author)A hollow matrix described by a graph G is a real symmetric matrix having all diagonal entries equal to zero and with the off-diagonal entries governed by the adjacencies in G. For a given graph G, the determination of all possible spectra of matrices associated with G is the hollow inverse eigenvalue problem for G. Solutions to the hollow...journal article 2022

Young, M.T.

In this article, I will explore how an exclusive focus on epistemology and theoretical reason can function to...journal article 2022

However, such measurements are presently limited by a small number of relatively coarse-spatial-resolution borehole records, especially for ice sheets. Here, we advance our understanding of glacier...journal article 2021

(author)Advances in light microscopy have enabled the visualization of DNA in the interphase nucleus with more detail than is visible with conventional light microscopy. The nuclear architecture is assumed to be different in cancer cells compared to normal cells. In this paper we have studied, for the first time, the organization of nuclear DNA and that...journal article 2014

Zhao, Q. (author), Young, I.T. (author), De Jong, J.G.S. (author)We have constructed a mathematical model to analyze the photon efficiency of frequency-domain fluorescence lifetime imaging microscopy (FLIM). The power of the light source needed for illumination in a FLIM system and the signal-to-noise ratio of the detector have led us to a photon “budget.” These measures are relevant to many fluorescence...journal article 2011
