We examine a database containing the results of Ar/Ar step-heating experiments performed on 194 basement K-feldspars to recover thermal history information. Qualitative examination of Ar/Ar systematics reveals that about half of the K-feldspars examined are sufficiently well-behaved to be suitable for thermal history analysis. Correlation algorithms are developed to quantitatively assess the de...

Rate constants for the unimolecular decomposition of peptide monomer and dimer ions by thermal and surface-induced dissociation (SID) are measured and compared. Rate constants for thermal dissociation are measured in a heated wide-bore capillary flow reactor attached in front of the capillary leading into the mass spectrometer. Thermal decomposition of the leucine enkephalin ion (YGGFL)H+ is ob...

Nanostructured materials are promising as thermoelectrics since thermal transport can be suppressed with little degradation in electrical properties, a crucial requirement for high-efficiency thermal energy conversion. Porous materials offer a flexible platform thanks to their extensive range of possible configurations and robust nature compared to other nanostructures. Although there has been ...

In this paper we review the possible radiation mechanisms for the observed non-thermal emission in clusters of galaxies, with a primary focus on the radio and hard X-ray emission. We show that the difficulty with the non-thermal, non-relativisitic Bremsstrahlung model for the hard X-ray emission, first pointed out by Petrosian (2001) using a cold target approximation, is somewhat alleviated whe...

Bud development of boreal trees in spring, once initiated, is driven by ambient air temperature, but the mechanism triggering bud development remains unclear. We determined if some aspect of the diurnal or seasonal light regime influences initiation of bud burst once the chilling requirement is met. We grew 3-year-old birch plantlets cloned from a mature tree of boreal origin in light condition...

We propose using optomechanical interaction to narrow the bandwidth of filter cavities for achieving frequency-dependent squeezing in advanced gravitational-wave detectors, inspired by the idea of optomechanically induced transparency. This can allow us to achieve a cavity bandwidth on the order of 100 Hz using small-scale cavities. Additionally, in contrast to a passive Fabry-Pérot cavity, the...
