Color and Memory

Effects of Color on Working Memory Performance Primary Investigator: Hanna Vafiades Associate Investigators: Tanner Clark, Sydney Susano, Alyssa Stephens The intersection of color and working memory is a fascinating but inconclusive domain of cognitive psychological research. Some studies have demonstrated that the color black is found to be the least stimulating in terms of attention and memory (Meacham 2005), whereas colors found in nature are effective in facilitating attention and memory in young children (Dutta & Baruah, 2018). Another study found that only images or image descriptions in grayscale are better for memory tasks and that color memory is poor for working memory exercises (Stjepić, 2021). In each trial of the present study, participants are randomly shown one of two image versions–one color image or one grayscale image–for five seconds. They then complete three primary school-level mathematics questions as a short diversion in attention before being asked questions about the previously-presented photograph as a measure of working memory. Participants completed 20 trials of this memory task. Our hypothesis was that participants would be able to recall color images more easily than grayscale images in short-term memory tasks. Results of the present study may provide better knowledge on the intersection of color and memory so that people can strengthen their working memories. Future directions may include examining the influence of color intensity and value on working memory. keywords: color vision, gray-scale, short-term memory, colors in natur

Catalytic intramolecular hydroamination of aminoallenes using titanium and tantalum complexes of sterically encumbered chiral sulfonamides

Catalysis using earth abundant metals is an important goal due to the relative scarcity and expense of precious metal catalysts. It would be even more beneficial to use earth abundant catalysts for the synthesis of common pharmaceutical structural motifs such as pyrrolidine and pyridine. Thus, developing titanium catalysts for asymmetric ring closing hydroamination is a valuable goal. In this work, four sterically encumbered chiral sulfonamides derived from naturally occurring amino acids were prepared. These compounds undergo protonolysis reactions with Ti(NMe₂)₄ or Ta(NMe₂)₅ to give monomeric complexes as determined by both DOSY NMR and X-ray crystallography. The resulting complexes are active for the ring closing hydroamination hepta-4,5-dienylamine to give a mixture of tetrahydropyridine and pyrrolidine products. However, the titanium complexes convert 6-methylhepta-4,5-dienylamine exclusively to 2-(2-methylpropenyl)pyrrolidine in higher enantioselectivity than those previously reported, with enantiomeric excesses ranging from 18–24%. The corresponding tantalum complexes were more selective with enantiomeric excesses ranging from 33–39%

The GstLAL Search Analysis Methods for Compact Binary Mergers in Advanced LIGO's Second and Advanced Virgo's First Observing Runs

After their successful first observing run (September 12, 2015 - January 12, 2016), the Advanced LIGO detectors were upgraded to increase their sensitivity for the second observing run (November 30, 2016 - August 26, 2017). The Advanced Virgo detector joined the second observing run on August 1, 2017. We discuss the updates that happened during this period in the GstLAL-based inspiral pipeline, which is used to detect gravitational waves from the coalescence of compact binaries both in low latency and an offline configuration. These updates include deployment of a zero-latency whitening filter to reduce the over-all latency of the pipeline by up to 32 seconds, incorporation of the Virgo data stream in the analysis, introduction of a single-detector search to analyze data from the periods when only one of the detectors is running, addition of new parameters to the likelihood ratio ranking statistic, increase in the parameter space of the search, and introduction of a template mass-dependent glitch-excision thresholding method.Comment: 12 pages, 7 figures, to be submitted to Phys.

The GstLAL template bank for spinning compact binary mergers in the second observation run of Advanced LIGO and Virgo

We describe the methods used to construct the aligned-spin template bank of gravitational waveforms used by the GstLAL-based inspiral pipeline to analyze data from the second observing run of Advanced LIGO and Virgo. The bank expands upon the parameter space covered during the first observing run, including coverage for merging compact binary systems with total mass between 2 $\mathrm{M}_{\odot}$ and 400 $\mathrm{M}_{\odot}$ and mass ratios between 1 and 97.989. Thus the systems targeted include merging neutron star-neutron star systems, neutron star-black hole binaries, and black hole-black hole binaries expanding into the intermediate-mass range. Component masses less than 2 $\mathrm{M}_{\odot}$ have allowed (anti-)aligned spins between $\pm0.05$ while component masses greater than 2 $\mathrm{M}_{\odot}$ have allowed (anti-)aligned between $\pm0.999$. The bank placement technique combines a stochastic method with a new grid-bank method to better isolate noisy templates, resulting in a total of 677,000 templates.Comment: 9 pages, 13 figure

Association Between Preoperative Patient Resilience and Patient-Reported Outcomes After Rotator Cuff Repair

Background: Mental and emotional health can affect outcomes after orthopaedic surgery, and patient resilience has been found to be significantly related to postoperative functional outcomes. Purpose: To evaluate the relationship between preoperative patient resilience and 2-year postoperative patient-reported outcomes after rotator cuff repair (RCR). It was hypothesized that patients with low preoperative resilience will have worse patient-reported outcomes at 2 years after RCR versus those with high resilience. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent primary arthroscopic RCR in 2020 at a single institution and completed the Brief Resilience Scale (BRS) preoperatively were identified. Other inclusion criteria were American Shoulder and Elbow Surgeons (ASES) and Single Assessment Numeric Evaluation (SANE) scores at the 2-year follow-up. Outcomes were compared in patients as divided into low resilience (BRS score \u3e1 SD below the mean), normal resilience (BRS score ≤1 SD of the mean), and high resilience (BRS score \u3e1 SD above the mean) groups. Results: Overall, 100 patients (52 male, 48 female; mean age, 60 ± 9 years) were included in this study. Mean BRS scores did not change significantly from preoperative to 2-year follow-up (3.8 ± 0.7 vs 3.9 ± 0.8, P =.404). All patients had preoperative ASES scores. Low-resilience patients (n = 17) had significantly lower preoperative ASES scores compared with normal (n = 64) and high resilience (n = 19) patients (35 vs 42 vs 54, respectively; P =.022). There were no significant group differences in postoperative outcomes (revision rate, ASES score, ASES score improvement from preoperative to 2-year follow-up, or SANE score). Multivariate analysis indicated that preoperative resilience was not significantly associated with ASES score improvement (β estimate = –5.64, P =.150), while resilience at 2-year follow-up was significantly related to ASES score improvement (β estimate = 6.41, P =.031). Conclusion: Patient-reported outcomes at 2-year follow-up did not differ based on preoperative patient resilience for arthroscopic RCR patients. Multivariate analysis also showed that preoperative resilience was not associated with improvement in ASES scores; however, resilience at 2-year follow-up was associated with ASES score improvement
