Cyclic Sieving of Increasing Tableaux and small Schr\"oder Paths

An increasing tableau is a semistandard tableau with strictly increasing rows and columns. It is well known that the Catalan numbers enumerate both rectangular standard Young tableaux of two rows and also Dyck paths. We generalize this to a bijection between rectangular 2-row increasing tableaux and small Schr\"oder paths. We demonstrate relations between the jeu de taquin for increasing tableaux developed by H. Thomas and A. Yong and the combinatorics of tropical frieze patterns. We then use this jeu de taquin to present new instances of the cyclic sieving phenomenon of V. Reiner, D. Stanton, and D. White, generalizing results of D. White and of J. Stembridge.Comment: 20 page

Chemical nonlinearities in relating intercontinental ozone pollution to anthropogenic emissions

Model studies typically estimate intercontinental influence on surface ozone by perturbing emissions from a source continent and diagnosing the ozone response in the receptor continent. Since the response to perturbations is non-linear due to chemistry, conclusions drawn from different studies may depend on the magnitude of the applied perturbation. We investigate this issue for intercontinental transport between North America, Europe, and Asia with sensitivity simulations in three global chemical transport models. In each region, we decrease anthropogenic emissions of NOx and nonmethane volatile organic compounds (NMVOCs) by 20% and 100%. We find strong nonlinearity in the response to NOx perturbations outside summer, reflecting transitions in the chemical regime for ozone production. In contrast, we find no significant nonlinearity to NOx perturbations in summer or to NMVOC perturbations year-round. The relative benefit of decreasing NOx vs. NMVOC from current levels to abate intercontinental pollution increases with the magnitude of emission reductions

The Effectiveness of a Hybrid Off-Job Crafting Intervention on Employees’ Psychological Needs Satisfaction and Well-Being

Off-job crafting entails deliberate changes people can make in their non-work activities to meet their personal goals and satisfy psychological needs. We conducted a quasi-experimental study with a waitlist control group in three organizations in Finland (N = 86) to evaluate whether participation in a hybrid off-job crafting intervention stimulates employees’ off-job crafting efforts and, in turn, enhances psychological need satisfaction, subjective vitality and work engagement. Intervention group participants took part in an off-job crafting workshop, set a personal crafting goal for the four-week intervention period, received support from a specifically designed smartphone app, and attended a reflection workshop. With a study design consisting of seven measurement occasions in the intervention group and four in the waitlist control group, we examined both the intra-individual and inter-individual effects of the intervention. Contrary to our expectations, intervention group participants did not improve in their off-job crafting efforts, needs satisfaction and well-being over time compared to their own baseline and the waitlist control group. We conducted a detailed process evaluation to shed light on the mechanisms possibly influencing the effectiveness of the intervention. Participants who made less progress with their goal, were less satisfied with the intervention, and participants who did not set a goal focusing on their least satisfied need, experienced a steeper decline in off-job crafting, needs satisfaction and well-being. Interestingly, setting a SMARTer goal and being a more active app user also had a negative effect on the development of one’s off-job crafting, needs satisfaction and well-being over time

Introduction : exploring forgiveness in nineteenth-century poetry

This essay serves as an introduction to the essays collected in the ‘Nineteenth-century Poetry and Forgiveness’ cluster. It takes as its foundation the recent turn to questions of hospitality, forgiveness and gift in the intra-disciplinary field of religion, philosophy and literature and highlights the centrality of these issues for reading nineteenth-century poetry. The essay argues that nineteenth-century poetry attempts to figure forgiveness as poetic sound and rhythm as a way of thinking reciprocal forgiving relationships between people. Part I contextualizes this argument and argues for an understanding of forgiveness through emotion. Part II offers an overview of the field of forgiveness scholarship and explores its relevance for nineteenth-century debate on the topic. Part III offers a way into thinking forgiveness as sound and rhythm in Wordsworth's poem ‘Airey-Force Valley’ through Martin Heidegger's reading of poetics and being

SUMO-targeted ubiquitin ligase (STUbL) Slx5 regulates proteolysis of centromeric histone H3 variant Cse4 and prevents its mislocalization to euchromatin

Centromeric histone H3, CENP-ACse4, is essential for faithful chromosome segregation. Stringent regulation of cellular levels of CENP-ACse4 restricts its localization to centromeres. Mislocalization of CENP-ACse4 is associated with aneuploidy in yeast and flies and tumorigenesis in human cells; thus defining pathways that regulate CENP-A levels is critical for understanding how mislocalization of CENP-A contributes to aneuploidy in human cancers. Previous work in budding yeast shows that ubiquitination of overexpressed Cse4 by Psh1, an E3 ligase, partially contributes to proteolysis of Cse4. Here we provide the first evidence that Cse4 is sumoylated by E3 ligases Siz1 and Siz2 in vivo and in vitro. Ubiquitination of Cse4 by the small ubiquitin-related modifier (SUMO)-targeted ubiquitin ligase (STUbL) Slx5 plays a critical role in proteolysis of Cse4 and prevents mislocalization of Cse4 to euchromatin under normal physiological conditions. Accumulation of sumoylated Cse4 species and increased stability of Cse4 in slx5∆ strains suggest that sumoylation precedes ubiquitin-mediated proteolysis of Cse4. Slx5-mediated Cse4 proteolysis is independent of Psh1, since slx5∆ psh1∆ strains exhibit higher levels of Cse4 stability and mislocalization than either slx5∆ or psh1∆ strains. Our results demonstrate a role for Slx5 in ubiquitin-mediated proteolysis of Cse4 to prevent its mislocalization and maintain genome stability

The U.S. CMS HL-LHC R&D Strategic Plan

The HL-LHC run is anticipated to start at the end of this decade and will pose a significant challenge for the scale of the HEP software and computing infrastructure. The mission of the U.S. CMS Software & Computing Operations Program is to develop and operate the software and computing resources necessary to process CMS data expeditiously and to enable U.S. physicists to fully participate in the physics of CMS. We have developed a strategic plan to prioritize R&D efforts to reach this goal for the HL-LHC. This plan includes four grand challenges: modernizing physics software and improving algorithms, building infrastructure for exabyte-scale datasets, transforming the scientific data analysis process and transitioning from R&D to operations. We are involved in a variety of R&D projects that fall within these grand challenges. In this talk, we will introduce our four grand challenges and outline the R&D program of the U.S. CMS Software & Computing Operations Program.Comment: CHEP2023 proceedings, to be published in EPJ Web of Conference
