The Cost Of Living In Larger Primate Groups Includes Higher Fly Densities, Jan F. Gogarten, Mueena Jahan, Sébastien Calvignac-Spencer, Colin A. Chapman, Tony L. Goldberg, Fabian H. Leendertz, Jessica M. Rothman

Publications and Research

Flies are implicated in carrying and mechanically transmitting many primate pathogens. We investigated how fly associations vary across six monkey species (Cercopithecus ascanius, Cercopithecus mitis, Colobus guereza, Lophocebus albigena, Papio anubis, and Piliocolobus tephrosceles) and whether monkey group size impacts fly densities. Fly densities were generally higher inside groups than outside them, and considering data from these primate species together revealed that larger groups harbored more flies. Within species, this pattern was strongest for colobine monkeys, and we speculate this might be due to their smaller home ranges, suggesting that movement patterns may influence fly–primate associations. Fly associations increase with …

Magnetic-Field-Dependent Stimulated Emission From Nitrogen-Vacancy Centers In Diamond, Felix A. Hahl, Lukas Lindner, Xavier Vidal, Tingpeng Luo, Takeshi Ohshima, Shinobu Onoda, Shuya Ishii, Alexander M. Zaitsev, Marco Capelli, Brant C. Gibson, Andrew D. Greentree, Jan Jeske

Publications and Research

Negatively charged nitrogen-vacancy (NV) centers in diamond are promising magnetic field quantum sensors. Laser threshold magnetometry theory predicts improved NV center ensemble sensitivity via increased signal strength and magnetic field contrast. Here, we experimentally demonstrate laser threshold magnetometry. We use a macroscopic high-finesse laser cavity containing a highly NV-doped and low absorbing diamond gain medium that is pumped at 532 nm and resonantly seeded at 710 nm. This enables a 64% signal power amplification by stimulated emission. We test the magnetic field dependency of the amplification and thus demonstrate magnetic field-dependent stimulated emission from an NV center ensemble. This emission …

Spotlight Report #6: Proffering Machine-Readable Personal Privacy Research Agreements: Pilot Project Findings For Ieee P7012 Wg, Noreen Y. Whysel, Lisa Levasseur

Publications and Research

What if people had the ability to assert their own legally binding permissions for data collection, use, sharing, and retention by the technologies they use? The IEEE P7012 has been working on an interoperability specification for machine-readable personal privacy terms to support this ability since 2018. The premise behind the work of IEEE P7012 is that people need technology that works on their behalf—i.e. software agents that assert the individual’s permissions and preferences in a machine-readable format.

Thanks to a grant from the IEEE Technical Activities Board Committee on Standards (TAB CoS), we were able to explore the attitudes of …

Weakly-Supervised Tumor Purity Prediction From Frozen H&E Stained Slides, Matthew Brendel, Vanesa Getseva, Majd Al Assaad, Michael Sigouros, Alexandros Sigaras, Troy Kane, Pegah Khosravi, Juan Miguel Mosquera, Olivier Elemento, Iman Hajirasouliha

Publications and Research

Background

Estimating tumor purity is especially important in the age of precision medicine. Purity estimates have been shown to be critical for correction of tumor sequencing results, and higher purity samples allow for more accurate interpretations from next-generation sequencing results. Molecular-based purity estimates using computational approaches require sequencing of tumors, which is both time-consuming and expensive.

Methods

Here we propose an approach, weakly-supervised purity (wsPurity), which can accurately quantify tumor purity within a digitally captured hematoxylin and eosin (H&E) stained histological slide, using several types of cancer from The Cancer Genome Atlas (TCGA) as a proof-of-concept.

Findings

Our model predicts …

Is The Phq-9 A Unidimensional Measure Of Depression? A 58,272-Participant Study, Renzo Bianchi, Jay Verkuilen, Sharon Toker, Irvin Sam Schonfeld, Markus Gerber, Elmar Brähler, Kurt Kroenke

Publications and Research

The PHQ-9 has become a measure of reference in depression research and clinical practice. However, the issue of the PHQ-9’s unidimensionality has not been fully elucidated, and the usability of the PHQ-9’s total score requires clarification. In this study, we examined the dimensionality, scalability, and monotonicity properties of the PHQ-9 as well as the scale’s total-score reliability. We did so based on exploratory structural equation modeling (ESEM) bifactor analysis and Mokken scale analysis (MSA). We relied on a total of 58,272 participants (63% female; Mage = 43, SDage = 13) from 29 samples involving seven different countries (e.g., Germany, the …

Asian Americans Challenge The Official Racial Nationalism Of The United States, Frank Wu

Publications and Research

The very definition of “Asian American,” which historically has been based upon the formal exclusion of this grouping, demonstrates the racial nationalism of the United States Racial nationalism is not new. It has been the norm in America (and arguably remains the norm elsewhere, including throughout Asia) to identify belonging to a shared race as essential to membership within a nation-state. This essay uses the Wong Kim Ark case, recognizing birthright citizenship for an individual of Chinese descent, and the Korematsu case, allowing the World War II internment of Japanese Americans, as a means of showing how government officials conceived …

Community Violence Intervention At The Roots (Cvi–R), Katheryne Pugliese, Paul Oder, Talib Hudson, Jeffrey A. Butts

Publications and Research

The crime and justice field recently started to label a wide array of violence prevention strategies as Community Violence Interventions. Many of these strategies depend on law enforcement and social services, but the most innovative approaches are community-centered and community-sourced. They are grassroots efforts that rely on the resources of neighborhoods and residents themselves, operating separately from law enforcement and traditional human services. Researchers from the John Jay College Research and Evaluation Center reviewed the history of community violence intervention strategies that operate at the grassroots level (or CVI-R) and examined evaluations of several community-centered approaches, providing recommendations for researchers …

Neoliberal Hegemonic Masculinity And Mcmindfulness: The Need For Buddhist Values And Principles In Mindful Masculinity Programs, David Forbes

Publications and Research

This paper explores how certain Buddhist-inspired principles such as impermanence of self and compassion for all (metta) and the practice of mindfulness can contribute to challenging ways in which young men adopt troublesome aspects of systemic patriarchy. It (1) briefly examines the problem of systemic patriarchy in its most dominant forms, neoliberal hegemonic masculinity and right-wing racist authoritarian masculinity; (2) critically discusses examples of mindfulness education and counseling programs for young men that have been severed from their Buddhist origins (McMindfulness) that attempt to challenge young men around patriarchal beliefs and thoughts but end up reproducing neoliberal hegemonic masculinity; (3) …

Attending To And Transforming Power Dynamics In Translanguaged Research Relationships And Methodology, Sara Vogel

Publications and Research

In this response to Lee (2022), I posit that translanguaging has prompted a re-evaluation of applied linguistics and sociolinguistics methodology in part because the theory has implicated issues of power dynamics and coloniality into the study of language. For this, if researchers wish to conduct research from translanguaging perspectives, it becomes necessary to recognize and attend to power dynamics in research design and methodology. This piece suggests some guiding questions for addressing power dynamics in one aspect of translanguaging methodology — forming research relationships. It explores how, in our relationships to our fields, we might promote answerability (Patel, 2014) for …

Look At All Those Big Knobs! Online Audio Technology Discourse And Sexy Gear Fetishes, Eliot Bates, Samantha Bennett

Publications and Research

Despite a predominantly digital, 21st century music production landscape, analogue hardware professional audio technologies persist. In the discoursal throes of the leading online audio technology message forum Gearslutz, such technologies are routinely objectified, sexualized, fetishized and socialized into gear. Situated in a contemporary critical, interdisciplinary framework of fetish, masculinity and sexuality studies, this research interrogates how audio technologies manufactured and intended for music production contexts become sexy. Applying a mixed-mode methodology, including an intensive discourse, image and material-semiotic analysis of an ‘epic’ sexy gear thread, we collated extensive data about technological fetishization. Sexy gear discourse articulates themes of voyeurism, acquisition, …

Correlations Between The Rotations And Magnetospheres Of The Terrestrial Planets And The Sun's Formation In Our Solar System, Fred J. Cadieu

Publications and Research

Correlations between the rotations of the terrestrial planets in our solar system and the magnetic field of the Sun have been previously noted. These correlations account for the opposite rotation of Venus as a result of the magnetic field of the Sun being dragged across the conducting core of Venus. Currently the Sun’s magnetic field is not sufficiently strong to account for the proposed correlations. But recently meteorite paleomagnetism measurements have indicated that during the Sun’s formation the magnetic field of the Sun was of sufficient strength to have resulted in the observed correlations. As a part of these correlations …

Longitudinal Patterns Of Suicidality Among Heroin Users In Johannesburg, South Africa: A Need For Suicide Screening And Intervention, Nirvana Morgan, Ellen-Ge Denton, Ugasvaree Subramaney, William Daniels, Tilman Steinert

Publications and Research

Objectives: The objective of the study was to longitudinally assess the outcomes and correlates of suicidal ideation and behavior (SIB) among heroin users who attended inpatient detoxification and psychosocial rehabilitation. SIB was assessed in 300 heroin users upon entry into inpatient detoxification (baseline) as well as 3-months (t1) (n = 252; 84%) and 9-months (t2) (n = 225; 75%) post treatment. Multivariable logistic regression was used to determine the demographic, clinical and treatment related factors that increased the risk for a high SIB score.

Results: From baseline to t1 there was a significant decrease in the proportion of …

Gender Equity Commission Priorities: An Archival Study And Prospects For The Future, Maria D' Agostino, Nicole M. Elias

Publications and Research

This research explores the priorities of the gender equity commission in New York City over forty-five years. Archival commission data was organized thematically to understand the history of gender equity and suggest future possibilities for gender equity beyond New York City. In our historical analysis, we see an expansion of the definition of gender and an adoption of an intersectional approach to gender. We identify four historical gender priorities: sexual harassment and violence, pay equity and economic advancement, health and safety, and gender recognition and celebration. To address systemic issues of gender inequity, we recommend local level administrators embed an …

Challenges In Migrating Imperative Deep Learning Programs To Graph Execution: An Empirical Study, Tatiana Castro Vélez, Raffi Khatchadourian, Mehdi Bagherzadeh, Anita Raja

Publications and Research

Efficiency is essential to support responsiveness w.r.t. ever-growing datasets, especially for Deep Learning (DL) systems. DL frameworks have traditionally embraced deferred execution-style DL code that supports symbolic, graph-based Deep Neural Network (DNN) computation. While scalable, such development tends to produce DL code that is error-prone, non-intuitive, and difficult to debug. Consequently, more natural, less error-prone imperative DL frameworks encouraging eager execution have emerged at the expense of run-time performance. While hybrid approaches aim for the "best of both worlds," the challenges in applying them in the real world are largely unknown. We conduct a data-driven analysis of challenges—and resultant bugs—involved …

Imaging Of Transmetallation And Chelation Phenomena Involving Radiological Contrast Agents In Mineral-Rich Fruits, Subhendra Sarkar, Zoya Vinokur, Bleidis Buitrago, Lin Mousa, Hayley Sanchez, Analia Basilicata, Jodi-Ann Douglas, Seanetta Reddock

Publications and Research

Exogenous heavy metals or non-metallic waste products, for example lanthanide or iodinated contrast media for radiological procedures, may interfere with the biochemical pools in patients and in common food sources, creating an excess buildup of exogenous compounds which may reach toxic levels. Although the mechanisms are unknown, our experiments were designed to test if this toxicity can be attributed to “transmetallation” or “chelation” reactions freeing up lanthanides or chelated transition metals in acidic fruits used as phantoms representing the biologically active and mineral-rich carbohydrate matrix. The rapid breakdown of stable contrast agents have been reported at a lower pH. The …

Treatment Of Gravitational Pulling Sensation In Patients With Mal De Debarquement Syndrome (Mdds): A Model-Based Approach, Sergei B. Yakushin, Theodore Raphan, Catherine Cho

Publications and Research

Perception of the spatial vertical is important for maintaining and stabilizing vertical posture during body motion. The velocity storage pathway of vestibulo-ocular reflex (VOR), which integrates vestibular, optokinetic, and proprioception in the vestibular nuclei vestibular-only (VO) neurons, has spatio-temporal properties that are defined by eigenvalues and eigenvectors of its system matrix. The yaw, pitch and roll eigenvectors are normally aligned with the spatial vertical and corresponding head axes. Misalignment of the roll eigenvector with the head axes was hypothesized to be an important contributor to the oscillating vertigo during MdDS. Based on this, a treatment protocol was developed using simultaneous …

A Tool For Rejuvenating Feature Logging Levels Via Git Histories And Degree Of Interest, Yiming Tang, Allan Spektor, Raffi Khatchadourian, Mehdi Bagherzadeh

Publications and Research

Logging is a significant programming practice. Due to the highly transactional nature of modern software applications, a massive amount of logs are generated every day, which may overwhelm developers. Logging information overload can be dangerous to software applications. Using log levels, developers can print the useful information while hiding the verbose logs during software runtime. As software evolves, the log levels of logging statements associated with the surrounding software feature implementation may also need to be altered. Maintaining log levels necessitates a significant amount of manual effort. In this paper, we demonstrate an automated approach that can rejuvenate feature log …

Moving Beyond Niceness: Reading Bell Hooks Into The Radical Potential For The Discipline, Alex J. Moffett-Bateau, Jenn M. Jackson

Publications and Research

In honor of bell hooks’ legacy, we engage with her Black feminist scholarship to parse out what she offers to the study of Black politics. We explore the ways hooks rebuffed compulsory calls for niceness and obligatory congeniality via respectability politics. By interrogating the politics of the Black middle class, we locate hooks’ intellectual works as a repudiation of a “politics of niceness” that seeks to maintain the violent status quo of white capitalist heteropatriarchy. We then draw out why the rejection of a politics of niceness matters within broader discussions of race, power, politics, and oppression.

Effectiveness And Safety Of Oral Anticoagulants In Non-Valvular Atrial Fibrillation Patients With Prior Bleeding Events: A Retrospective Analysis Of Administrative Claims Databases, G. Y. H. Lip, Allison V. Keshishian, Amiee Kang, Xuemei Luo, Nipun Atreja, Yan Zhang, Patricia Schuler, Jenny Jiang, Huseyin Yuce, Steve Deitelzweig

Publications and Research

Introduction

There are a paucity of real-world data examining effectiveness and safety of non-vitamin K antagonist oral anticoagulants (NOACs) and warfarin in nonvalvular atrial fibrillation (NVAF) patients with prior bleeding.

Methods

This retrospective analysis included data from 5 insurance claims databases and included NVAF patients prescribed OACs with prior bleeding. One-to-one propensity score matching was conducted between NOACs and warfarin and between NOACs in each database. Cox proportional hazards models were used to evaluate the risk of stroke/systemic embolism (SE) and MB.

Results

A total of 244,563 patients (mean age 77; 50% female) with prior bleeding included 55,094 (22.5%) treated …

X-Ray And Mri Theory For Mineral-Rich Fruits Affected By Heat Waves During Climate Change, Daler Djuraev, Somdat Kissoon, Robert O'Brien, Nino Jvarishvil

Publications and Research

Conventional Nutrition facts data relays the amounts of different minerals in apples. This information from such analysis may not connect these minerals with their natural biochemical or functional state for health or disease. These minerals may also be part of different particle sizes that affects X-ray transmission, absorption and scatter. The minerals may also redistribute within the tissue over time with or without heat shock. Current Medical Imaging procedures (Xray and MRI) do not localize such minerals. Our work offers a way to increase detection sensitivity of transition metals in various apple varieties non-invasively. This can constitute a step in …

Large-Herbivore Nemabiomes: Patterns Of Parasite Diversity And Sharing, Georgia C. Titcomb, Johan Pansu, Matthew C. Hutchinson, Kaia J. Tombak, Christina B. Hansen, Christopher C. M. Baker, Tyler R. Kartzinel, Robert M. Pringle

Publications and Research

Amidst global shifts in the distribution and abundance of wildlife and livestock, we have only a rudimentary understanding of ungulate parasite communities and parasite-sharing patterns. We used qPCR and DNA metabarcoding of fecal samples to characterize gastrointestinal nematode (Strongylida) community composition and sharing among 17 sympatric species of wild and domestic large mammalian herbivore in central Kenya. We tested a suite of hypothesis-driven predictions about the role of host traits and phylogenetic relatedness in describing parasite infections. Host species identity explained 27 – 53% of individual variation in parasite prevalence, richness, community composition and phylogenetic diversity. Host and parasite phylogenies …

On Power’S Doorstep: Gays, Jews, And Liminal Complicity In Reproducing Masculine Domination, Andrew J. Shapiro

Publications and Research

This article explores the gender complexities of men caught between social power and powerlessness. Specifically, I consider the cases of Jewish men and gay men in the late modern West, two demographics with deep historic ties to both abjection and privilege. Such "in-between-ness” steers many, especially those who are white, cisgender, and/or otherwise privileged, toward what I term liminal complicity, a normative adaptation whereby men embrace manly ideals while disavowing femininity in themselves and others. I synthesize cultural, interactionist, and psychoanalytic literatures on stigma, boundaries, and gender practice to articulate liminal complicity as both an emotional retreat from stigmatization and …

Lake Satellite Temperature Data Validation, Mamadou Balde, Pascal Kouogang

Publications and Research

In environmental remote sensing, satellite data isn't absolutely conclusive, for that reason, there is a natural need to verify the data acquired from the satellite. The most suitable tool to achieve such verification is on ground sensors that have the advantage of proximity. Addressing any possible discrepancies between the satellite data and the ground sensor data is sure to yield ways to come up with improvements of satellite band calibration and sensing capabilities. This research focused on correlating temperature data from the MODIS satellite with the data obtained from the In Situ sensor located in Lake Sunapee. Doing the latter …
