Speculative Automated Refactoring Of Imperative Deep Learning Programs To Graph Execution, Raffi Khatchadourian Ph.D., Tatiana Castro Vélez, Mehdi Bagherzadeh, Nan Jia, Anita Raja

Publications and Research

Efficiency is essential to support ever-growing datasets, especially for Deep Learning (DL) systems. DL frameworks have traditionally embraced deferred execution-style DL code---supporting symbolic, graph-based Deep Neural Network (DNN) computation. While scalable, such development is error-prone, non-intuitive, and difficult to debug. Consequently, more natural, imperative DL frameworks encouraging eager execution have emerged but at the expense of run-time performance. Though hybrid approaches aim for the "best of both worlds," using them effectively requires subtle considerations. Our key insight is that, while DL programs typically execute sequentially, hybridizing imperative DL code resembles parallelizing sequential code in traditional systems. Inspired by this, we …

Analysis Of Libraries’ Onboarding Documentation At A Metropolitan University Consortium, Sonali Sugrim, Eric Silberberg

Urban Library Journal

This study investigates the extent to which onboarding documentation for academic librarians prioritizes long-term employee success. The authors applied content analysis to the onboarding documents from a consortium of libraries in a major metropolitan area in the United States. Study findings reveal that the onboarding documents prioritize introducing new hires to organizational structure rather than integrating them into the workplace culture. Most documents are checklists; however, some libraries provide comprehensive manuals, particularly regarding the tenure process. Notably, only half of the libraries include information about mentorship programs. Based on these findings, this study offers recommendations for improving onboarding documentation, including …

Untargeted Metabolomics Reveals Organ-Specific And Extraction-Dependent Metabolite Profiles In Endemic Tajik Species Ferula Violacea Korovin, Sylhiya Mavlonazarova, Kenneth Acosta, Rinat Abzalimov, Saidbeg Satorov, Vyacheslav Dushenkov

Publications and Research

Ferula violacea Korovin, an endemic Tajikistani plant with purported medicinal properties, remains understudied. This study employs untargeted metabolomics to characterize the metabolite profiles of ethanol extracts and juices from F. violacea roots and seeds. In total, 540 distinct metabolites are putatively identified, 419 of which are previously unreported in the Ferula genus, representing a substantial expansion of its known chemical diversity. The most abundant metabolites are terpenoids, amino acid derivatives, and alkaloids. A particularly abundant group of daucane sesquiterpenoids, sharing a common (6-methyl-azulen-4-yl) cyclohexanecarboxylate substructure, is identified, including known metabolites such as ferutidin and ferutinin. Comparative analysis reveals organ-specific metabolic …

Electric-Field Tunable Magnetoexcitons In Xenes/Hbn/Tmdc, Xenes/Hbn/Bp, And Xenes/Hbn/Tmtc Heterostructures, Roman Ya. Kezerashvili, Anastasia Spiridonova, Klaus Ziegler

Publications and Research

In this work, we propose novel van der Waals heterostructures composed of Xenes, transition metal dichalcogenides (TMDCs), phosphor ene, and transition metal trichalcogenides (TMTCs), which are separated by insulating hexagonal boron nitride (hBN) layers. We theoreti cally investigate the behavior of Rydberg indirect excitons in Xenes/hBN/TMDC, Xenes/hBN/phosphorene and Xenes/hBN/TMTC heterostructures subjected to parallel external electric and magnetic fields that are oriented perpendicular to the layers. By incorporating both isotropic and anisotropic materials, we demonstrate that excitonic properties can be effectively tuned through the external field strengths and the heterostructure design. Our results show that the exciton reduced mass and the …

Challenges In Developing Physical Intuition In College General Physics Courses, Vasiliy S. Znamenskiy, Rafael Niyazov

Open Educational Resources

Many students can memorize formulas but struggle to feel what a newton, joule, or volt means; they treat formulas as plug-and-chug templates rather than descriptions of relationships among physical quantities. This presentation introduces three types of learning activities: (1) text-free (“no-text”) problems, in which carefully designed visuals replace prose to convey relationships and constraints; (2) anti-problems, which begin with a mathematical expression and ask students to imagine a physical situation it could describe; and (3) lab games that turn routine measurement into purposeful play, emphasizing estimation, scaling, and unit sense. We provide ready-made, Brightspace-compatible assessments alongside low-tech implementation options. The …

Beyond “A Purely Passive Servitude”:Antonio Oblitas, Casta, And Afro-Descendants In The Rebellion Of TúPac Amaru Ii, Tacuma Peters

Publications and Research

This article examines the contributions of Afro-descendants to the Túpac Amaru II rebellion in Peru. It argues that although historians have recognized the importance of race and casta in the rebellion, they have been insufficiently attentive to the complex roles that those of African descent have played. It argues that the most famous Afro-descendant, Antonio Oblitas, has often been ignored, misidentified, and minimized in his aesthetic and visual contributions to the uprising. This problematic historical approach extends to other free and enslaved men because scholars place them within the paradigm of passive (and enslaved) servitude. Furthermore, the article contends that …

Feminist Scholarly Editing: A Provocation, Marlowe Daly-Galeano, Melissa J. Homestead, Claudia Stokes, Leila Walker

Publications and Research

This essay examines the feminist challenges posed by the protocols and history of scholarly editing. Prompted by the recent revival of bibliographical studies, the essay seeks to instigate a similar reconsideration of scholarly editing, bibliography’s counterpart in textual criticism. Scholarly editing has a vexed history with regard to women and gender: women writers were seldom the beneficiaries of editorial attention, but editors regularly used gendered metaphors to describe their work and often relied on the unacknowledged labor of women. This essay examines the history of sexism within the field of scholarly editing, illustrates the challenges and promises of editing women’s …

Ten immigrant Latine participants, nine mothers and one grandmother, whose children attended traditional or charter elementary schools in one NYC district, shared their experiences through semi-structured interviews conducted in Spanish. Data were analyzed through iterative coding and thematic analysis …

Cross-Cultural Validity Of The Ppi-R In U.S. College Students, Cassidy Liang

Student Theses

Psychopathy has traditionally been studied using Hare's Psychopathy Checklist-Revised (PCL-R) but self-report measures like the Psychopathic Personality Inventory-Revised (PPI-R) have gained popularity due to comparative ease, speed of administration, and its broader applicability to the general population. However, the validity of the PPI-R across cultures has produced mixed results, particularly in non-Western and non-English speaking participants. This study examined racial/ethnic and gender differences in the PPI-R in a diverse sample of 536 college students. The internal and external validity of the PPI-R was good. The PPI-R correlated with the Triarchic Psychopathy Measure (TriPM), as well as trait anxiety, and empathy …

A Few Millimeters Of Bone: How Male Supremacists Leverage Scientific Sexism To Reinforce Misogynistic Ideologies, Robin O'Hanlon

Publications and Research

In recent years, male supremacist actors have reinforced their misogynistic worldviews by using narrative strategies centered on authoritative “common sense” and scientific “fact.” This paper presents a thematic narrative analysis of The Incel Wiki and the Wiki4Men, representing the first formal analysis of the wiki for the men’s rights organization A Voice for Men. The analysis indicates male supremacists use techniques including misappropriation of scientific information, manipulation of statistics, and leveraging pseudoscientific information to develop their narrative strategies of supremacy. The most consistent narrative strategies of scientific sexism on the wikis are male victimhood, denial of inequality between men and …
