What Got Us Here, Won’T Get Us There: Why U.S. Commercial Space Policy Must Lie In An Independent Regulatory Agency, Gerardo Inzunza Higuera Jan 2022

What Got Us Here, Won’T Get Us There: Why U.S. Commercial Space Policy Must Lie In An Independent Regulatory Agency, Gerardo Inzunza Higuera

UC Law Journal

This Note addresses the need for a comprehensive, centralized independent agency designated solely for the management of commercial space activities. The current commercial “space rush” promises unimaginable possibilities and profits for a burgeoning sector, yet no single federal agency has been entrusted with the regulation of this nascent industry. Currently, the United States has settled into an inefficient, fragmented regulatory approach that unduly burdens commercial players and frustrates its national objective of fostering a robust commercial low- Earth orbit economy. This Note analyzes proposals by Congress for such a new regulatory agency and concludes by proposing a new framework that …

Turkish Journal of Veterinary & Animal Sciences

Dirofilaria immitis (D. immitis); is a parasitic zoonosis with a prevalence of 53.8%, whose intermediate host is mosquitoes (Anopheles, Aedes, Culex, Taeniorhychus, Mansonia and Armigenes), final hosts are carnivores (dog, cat, fox, etc.) and humans. The causative agent settles in the pulmonary arteries and causes pulmonary hypertension, which can progress to congestive heart failure. Cardiac troponins (cTn), which have recently been used in veterinary cardiology, are considered the gold standard because of their high sensitivity and specificity for myocardial injury. In the study, high-sensitivity cardiac troponin T (hs-cTnT) and high-sensitivity cardiac troponin I (hs-cTnI) levels in healthy …

A Phylogeny Of Antirrhinum Reveals Parallel Evolution Of Alpine Morphology, Mario Durán-Castillo, Andrew Hudson, Yvette Wilson, David L. Field, Alex D. Twyford Jan 2022

A Phylogeny Of Antirrhinum Reveals Parallel Evolution Of Alpine Morphology, Mario Durán-Castillo, Andrew Hudson, Yvette Wilson, David L. Field, Alex D. Twyford

Research outputs 2014 to 2021

Parallel evolution of similar morphologies in closely related lineages provides insight into the repeatability and predictability of evolution. In the genus Antirrhinum (snapdragons), as in other plants, a suite of morphological characters are associated with adaptation to alpine environments.

We tested for parallel trait evolution in Antirrhinum by investigating phylogenetic relationships using restriction-site associated DNA (RAD) sequencing. We then associated phenotypic information to our phylogeny to reconstruct the patterns of morphological evolution and related this to evidence for hybridisation between emergent lineages.

Phylogenetic analyses showed that the alpine character syndrome is present in multiple groups, suggesting that Antirrhinum has repeatedly …
