Taxing Judicial Restraint: How Washington\u27s Supreme Court Misinterpreted its Role and the Washington State Constitution
In the realm of constitutional interpretation, the judicial department reigns supreme. League of Education Voters v. State exemplifies the judiciaryâs potential abuse of its interpretative role: The Washington Supreme Court misinterpreted its judicial function because it ignored the text of Washington Stateâs constitution and held a statute unconstitutional. The court, therefore, voided a statute because of judicial volition, not because Washingtonâs constitution demanded that outcome. This Note challenges the reasoning in League and makes a novel suggestion for Washington State constitutional analysis, an approach that may apply to other states. This Note details a new analytical framework for constitutional analysis through the reformed beyond-a-reasonable-doubt doctrine and applies that framework to the Supermajority issue addressed in League
An Analysis of the Global Oil Market in 2020
Twenty-twenty represented one of the most volatile periods of history for the oil market. This volatility was reflected in market prices, with oil futures going negative in April 2020 and ending the year closer to pre-pandemic levels. As the year progressed, geopolitical tensions, a global pandemic, price wars, hurricanes, and vaccine innovation all contributed to the fluctuations in global demand and supply for oil. The year opened in January with oil prices rising following U.S. airstrikes targeting an Iranian high-ranking military official. February and March saw the beginning of the Covid-19 pandemic, which ushered in a dramatic demand shock unprecedent in market history. Aprilâs negative futures prices were the result of an oversupplied market meeting this historic demand deficit. May and June saw the continuation of the Covid-19 demand trend. However, July and August were met with a significant resurgence in Covid-19 in many parts of the world and hurricanes that battered U.S. oil production. September and October saw both economic and political development, particularly in the United States, dampen projections for future demand. Finally, the last two months of the year saw renewed hope that demand challenges would eventually be solved with the emergency authorization of Covid-19 vaccines
A Sting in the Night: Pallid Bat Detection of Dangerous Prey
It has been observed in previous studies that Hemprich long-eared bats (Otonycteris hemprichii) are frequently stung during predation attacks on scorpions. Although a highly toxic and dangerous prey, the scorpion toxicity does not kill the bat. The sting, however, does seem to inflict a great amount of pain. Here, we examine the role of bat vision in predator-prey interactions between a similar bat species, pallid bats (Antrozous pallidus) and northern scorpions (Paruroctonus boreus). We address the question: do bats use visual information provided by moonlight to plan attacks on dangerous prey? We predicted that under moonlit conditions, pallid bats would plan attacks on scorpion prey, therefore, being stung less often. Our experiments took place in a flight room in both simulated moonlight and complete darkness. The interactions were recorded live by three high-definition cameras mounted in three separate corners of the interaction arena

Compositions Utilizing Fractal Flame Algorithms
âMusic, by its very abstract nature, is the first of the arts to have attempted
reconciliation of artistic creation with scientific thoughtâ
â Xenakis, 1992
This portfolio explores how the iterative and recursive processes employed within
fractal flame algorithms can be used to create new and aesthetically pleasing
micro and macro sounds from which coherent compositions can be created. A
variety of existing electronic compositional procedures, including wave-set
substitution and granular synthesis, as well as a number of classical compositional
practices, such as hocketing, are deployed to generate a complex and diverse set
of compositions. The portfolio shows how marrying these sound manipulating
techniques and compositional processes with the sonic events produced by the
unexplored field of fractal flame algorithms has allowed me to generate â in the
words of Iannis Xenakis â âsounds that have never existed beforeâ. The portfolio
shows the creative potential fractal flame programs have for electronic music
generation and how they offer a terra nova (new earth) upon which computergenerated
music can lay down solid foundations and expand in new directions to
harvest exciting results
Model for the Induction of Spike Timing-Dependent Plasticity by Pre- and Postsynaptic Spike Trains
Spike timing-dependent plasticity (STDP), a process in which changes in synaptic strength are determined by the relative timing of pre- and postsynaptic activity, has been studied and modeled by a number of researchers, but many questions still remain. It has been suggested that STDP involves a postsynaptic chemical network with stable states corresponding to long term potentiation (LTP) and long term depression (LTD). It is believed that the switching between these states is driven by the postsynaptic Ca2+ concentration, but the manner in which the Ca2+ dynamics is able to trigger either LTP or LTD, depending on the relative timing of pre- and postsynaptic activity remains unclear.
We have investigated a model of STDP that combines (1) the tristable chemical network involving CaMKII and PP2A studied by Pi and Lisman [1], with (2) compartmental modeling of backpropagating action potentials (BPAPs), N-methyl D-aspartate receptors (NMDARs), and voltage-dependent calcium channels (VDCCs). In previous work we have studied how this model responds when a presynaptic pulse arrives either shortly before or shortly after a postsynaptic pulse (a BPAP), and shown how this model leads naturally to LTP when the presynaptic pulse arrives first, or LTD when the postsynaptic pulse arrives first, in agreement as found in experimental studies (e.g., [2] and [3]). The response to spike triplets and other more complex pre- and postsynaptic spike trains are also of interest. Experiments [4] have shown that the response to such multispike trains is not simply the sum of the responses to the component spike pairs. For example, the response to a spike triplet consisting of pre-post-presynaptic spikes is often not explained by the simple addition of the responses to a pre-post spike pair followed by a post-pre spike pair. Previous work has proposed only heuristic rules for such multispike responses. In this paper we describe the application of our model of STDP to multispike situations. Our model exhibits a non-additive response similar to that observed by Wang et al. [4], and gives insight into how this non-additivity arises from properties of the CaMKII/PP2A network
Robust Detection of Dynamic Community Structure in Networks
We describe techniques for the robust detection of community structure in
some classes of time-dependent networks. Specifically, we consider the use of
statistical null models for facilitating the principled identification of
structural modules in semi-decomposable systems. Null models play an important
role both in the optimization of quality functions such as modularity and in
the subsequent assessment of the statistical validity of identified community
structure. We examine the sensitivity of such methods to model parameters and
show how comparisons to null models can help identify system scales. By
considering a large number of optimizations, we quantify the variance of
network diagnostics over optimizations (`optimization variance') and over
randomizations of network structure (`randomization variance'). Because the
modularity quality function typically has a large number of nearly-degenerate
local optima for networks constructed using real data, we develop a method to
construct representative partitions that uses a null model to correct for
statistical noise in sets of partitions. To illustrate our results, we employ
ensembles of time-dependent networks extracted from both nonlinear oscillators
and empirical neuroscience data.Comment: 18 pages, 11 figure
Music\u27s Emotional Journey
Music has an emotion-evoking effect on its audience through form. This is exemplified throughout history, but we will be focusing on \u27Don\u27t Stop Believin\u27 \u27 by Journey as a prime example. Part of this influence is due to the fact that it contrast with other widely-used forms. Presentation Time: Thursday, 3-4 p.m

The definitive version was published in Liu, S., Parsons, R., Opalk, K., Baetge, N., Giovannoni, S., Bolanos, L. M., Kujawinski, E. B., Longnecker, K., Lu, Y., Halewood, E., & Carlson, C. A. Different carboxyl-rich alicyclic molecules proxy compounds select distinct bacterioplankton for oxidation of dissolved organic matter in the mesopelagic Sargasso Sea. Limnology and Oceanography, (2020), doi:10.1002/lno.11405.Marine dissolved organic matter (DOM) varies in its recalcitrance to rapid microbial degradation. DOM of varying recalcitrance can be exported from the ocean surface to depth by subduction or convective mixing and oxidized over months to decades in deeper seawater. Carboxylârich alicyclic molecules (CRAM) are characterized as a major component of recalcitrant DOM throughout the oceanic water column. The oxidation of CRAMâlike compounds may depend on specific bacterioplankton lineages with oxidative enzymes capable of catabolizing complex molecular structures like longâchain aliphatics, cyclic alkanes, and carboxylic acids. To investigate the interaction between bacteria and CRAMâlike compounds, we conducted microbial remineralization experiments using several compounds rich in carboxyl groups and/or alicyclic rings, including deoxycholate, humic acid, lignin, and benzoic acid, as proxies for CRAM. Mesopelagic seawater (200âm) from the northwest Sargasso Sea was used as media and inoculum and incubated over 28âd. All amendments demonstrated significant DOC removal (2â11âÎŒmol C Lâ1) compared to controls. Bacterioplankton abundance increased significantly in the deoxycholate and benzoic acid treatments relative to controls, with fastâgrowing Spongiibacteracea, Euryarcheaota, and slowâgrowing SAR11 enriched in the deoxycholate treatment and fastâgrowing Alteromonas, Euryarcheaota, and Thaumarcheaota enriched in the benzoic acid treatment. In contrast, bacterioplankton grew slower in the lignin and humic acid treatments, with oligotrophic SAR202 becoming significantly enriched in the lignin treatment. Our results indicate that the character of the CRAM proxy compounds resulted in distinct bacterioplankton removal rates of DOM and affected specific lineages of bacterioplankton capable of responding.We thank Z.
