SCORING A CHILDHOOD FAVORITE: The Grim Adventures of Billy and Mandy: Dream a Little Dream
The contents of this paper are the culmination of all the knowledge, experiences and work acquired during the year of Master of Music in Scoring for Film, Television and Video Games. Using all that we had learned, we started by finding some media that we would like to score (short film, animation, video game, script, etc.), and the tempo and markers in the media, create a mock-up and several revisions of our score for the media, prepare the score and parts, prepare for recording in one of the most esteemed and respected studios in the world, and mixing/mastering the recording for premier. Having gone to undergraduate for composition, I felt comfortable in my composition, orchestration, and preparatory skills coming into the program. I knew that my biggest challenges would be reading scenes to extract the emotion out of them and creating realistic mock-ups. I had done a little work with mock-ups and scoring for media in my undergraduate, but never really dedicated much time to either of these things. I wanted my thesis project to really showcase my style and be unlike anything else I had done before. I also knew that it was going to be hard work, but it would be worth it. This year has certainly been a strange one with the coronavirus breakout, especially with the thesis project. I hope that someone looking at this reflection in the future might be inspired, guided, and/or calmed by seeing what it was like to prepare this project in the midst of a pandemic, when nothing is certain and everything is changing all the time.https://remix.berklee.edu/graduate-studies-scoring/1163/thumbnail.jp
A Trapped Field of 17.6 T in Melt-Processed, Bulk Gd-Ba-Cu-O Reinforced with Shrink-Fit Steel
The ability of large grain, REBaCuO [(RE)BCO; RE =
rare earth] bulk superconductors to trap magnetic field is determined by their
critical current. With high trapped fields, however, bulk samples are subject
to a relatively large Lorentz force, and their performance is limited primarily
by their tensile strength. Consequently, sample reinforcement is the key to
performance improvement in these technologically important materials. In this
work, we report a trapped field of 17.6 T, the largest reported to date, in a
stack of two, silver-doped GdBCO superconducting bulk samples, each of diameter
25 mm, fabricated by top-seeded melt growth (TSMG) and reinforced with
shrink-fit stainless steel. This sample preparation technique has the advantage
of being relatively straightforward and inexpensive to implement and offers the
prospect of easy access to portable, high magnetic fields without any
requirement for a sustaining current source.Comment: Updated submission to reflect licence change to CC-BY. This is the

Metabolic reprogramming of human CD8+ memory T cells through loss of SIRT1.
The expansion of CD8+CD28- T cells, a population of terminally differentiated memory T cells, is one of the most consistent immunological changes in humans during aging. CD8+CD28- T cells are highly cytotoxic, and their frequency is linked to many age-related diseases. As they do not accumulate in mice, many of the molecular mechanisms regulating their fate and function remain unclear. In this paper, we find that human CD8+CD28- T cells, under resting conditions, have an enhanced capacity to use glycolysis, a function linked to decreased expression of the NAD+-dependent protein deacetylase SIRT1. Global gene expression profiling identified the transcription factor FoxO1 as a SIRT1 target involved in transcriptional reprogramming of CD8+CD28- T cells. FoxO1 is proteasomally degraded in SIRT1-deficient CD8+CD28- T cells, and inhibiting its activity in resting CD8+CD28+ T cells enhanced glycolytic capacity and granzyme B production as in CD8+CD28- T cells. These data identify the evolutionarily conserved SIRT1-FoxO1 axis as a regulator of resting CD8+ memory T cell metabolism and activity in humans
An Infinite Dimensional Symmetry Algebra in String Theory
Symmetry transformations of the space-time fields of string theory are
generated by certain similarity transformations of the stress-tensor of the
associated conformal field theories. This observation is complicated by the
fact that, as we explain, many of the operators we habitually use in string
theory (such as vertices and currents) have ill-defined commutators. However,
we identify an infinite-dimensional subalgebra whose commutators are not
singular, and explicitly calculate its structure constants. This constitutes a
subalgebra of the gauge symmetry of string theory, although it may act on
auxiliary as well as propagating fields. We term this object a {\it weighted
tensor algebra}, and, while it appears to be a distant cousin of the
-algebras, it has not, to our knowledge, appeared in the literature before.Comment: 14 pages, Plain TeX, report RU93-8, CTP-TAMU-2/94, CERN-TH.7022/9
Cache valley virus in a patient diagnosed with aseptic meningitis
Cache Valley virus was initially isolated from mosquitoes and had been linked to central nervous system-associated diseases. A case of Cache Valley virus infection is described. The virus was cultured from a patient's cerebrospinal fluid and identified with real-time reverse transcription-PCR and sequencing, which also yielded the complete viral coding sequences
Colorectal polyp outcomes after participation in the seAFOod polyp prevention trial: Evidence of rebound elevated colorectal polyp risk after short-term aspirin use
BACKGROUND: The seAFOod polyp prevention trial was a randomised, placebo-controlled, 2 × 2 factorial trial of aspirin 300 mg and eicosapentaenoic acid (EPA) 2000 mg daily in individuals who had a screening colonoscopy in the English Bowel Cancer Screening Programme (BCSP). Aspirin treatment was associated with a 20% reduction in colorectal polyp number at BCSP surveillance colonoscopy 12 months later. It is unclear what happens to colorectal polyp risk after short-term aspirin use. AIM: To investigate colorectal polyp risk according to the original trial treatment allocation, up to 6 years after trial participation. METHODS: All seAFOod trial participants were scheduled for further BCSP surveillance and provided informed consent for the collection of colonoscopy outcomes. We linked BCSP colonoscopy data to trial outcomes data. RESULTS: In total, 507 individuals underwent one or more colonoscopies after trial participation. Individuals grouped by treatment allocation were well matched for clinical characteristics, follow-up duration and number of surveillance colonoscopies. The polyp detection rate (PDR; the number of individuals who had ≥1 colorectal polyp detected) after randomization to placebo aspirin was 71.1%. The PDR was 80.1% for individuals who had received aspirin (odds ratio [OR] 1.13 [95% confidence interval 1.02, 1.24]; p = 0.02). There was no difference in colorectal polyp outcomes between individuals who had been allocated to EPA compared with its placebo (OR for PDR 1.00 [0.91, 1.10]; p = 0.92). CONCLUSION: Individuals who received aspirin in the seAFOod trial demonstrated increased colorectal polyp risk during post-trial surveillance. Rebound elevated neoplastic risk after short-term aspirin use has important implications for aspirin cessation driven by age-related bleeding risk. ISRCTN05926847
Cyclic DI-GMP Phosphodiesterases RmdA and RmdB are involved in regulating colony morphology and development in Streptomyces coelicolor. Journal of Bacteriology
Cyclic dimeric GMP (c-di-GMP) regulates numerous processes in Gram-negative bacteria, yet little is known about its role in Gram-positive bacteria. Here we characterize two c-di-GMP phosphodiesterases from the filamentous high-GC Gram-positive actinobacterium Streptomyces coelicolor, involved in controlling colony morphology and development. A transposon mutation in one of the two phosphodiesterase genes, SCO0928, hereby designated rmdA (regulator ofmorphology and development A), resulted in decreased levels of spore-specific gray pigment and a delay in spore formation. The RmdA protein contains GGDEF-EAL domains arranged in tandem and possesses c-di-GMP phosphodiesterase activity, as is evident from in vitro enzymatic assays using the purified protein. RmdA contains a PAS9 domain and is a hemoprotein. Inactivation of another GGDEF-EAL-encoding gene, SCO5495, designated rmdB, resulted in a phenotype identical to that of the rmdA mutant. Purified soluble fragment of RmdB devoid of transmembrane domains also possesses c-di-GMP phosphodiesterase activity. ThermdA rmdB double mutant has a bald phenotype and is impaired in aerial mycelium formation. This suggests that RmdA and RmdB functions are additive and at least partially overlapping. The rmdA and rmdB mutations likely result in increased local pools of intracellular c-di-GMP, because intracellular c-di-GMP levels in the single mutants did not differ significantly from those of the wild type, whereas in the double rmdA rmdB mutant, c-di-GMP levels were 3-fold higher than those in the wild type. This study highlights the importance of c-di-GMP-dependent signaling in actinomycete colony morphology and development and identifies two c-di-GMP phosphodiesterases controlling these processes
