Rvit-Fusionnet: A Local Cross-Attention Feature Fusion-Based Hybrid Framework For Brain Tumor Classification, Naima Islam, Sajeeb Kumar Ray, Md Anwar Hossain, Syed Mohammed Shamsul Islam

Research outputs 2022 to 2026

Accurate brain tumor classification via MRI is essential for diagnosis and treatment. This study introduces RViT-FusionNet, a hybrid deep learning model that integrates convolutional and transformer architectures for enhanced tumor detection. The model utilizes ResNet-50 to capture textural details and a Vision Transformer for extracting global context. A Local Cross-Attention (LCA) module is proposed to align and merge these features, allowing the network to model local structures and long-range dependencies concurrently. To enhance generalization across varied imaging conditions and tumor types, a domain discriminator is included to discern spatial and domain-specific patterns, fostering the learning of domain-invariant representations. The approach …

Spatiotemporal Dynamics Of Riparian Land-Cover Change And Impervious-Cover Expansion In A Rapidly Urbanising Himalayan Capital City, Karma Jamtsho, Tashi Dorji, David Blake, Mark A. Lund, Eddie Van Etten

Research outputs 2022 to 2026

Urbanisation and impervious-cover expansion are reshaping riparian landscapes, particularly in mountain cities where steep terrain concentrates development along valley floors. This study examined spatiotemporal land-cover change within the regulated riparian corridors of Thimphu City, Bhutan, over a 25-year period from 1997 to 2022 using Landsat imagery, Random Forest classification and Google Earth Engine. Results show substantial transformation of riparian land cover, with impervious cover increasing from 26.14% to 32.63%, equivalent to an overall increase of 24.83%, while agriculture/barren/low-vegetation declined from 30.59% to 26.01%, equivalent to an overall decrease of 14.98%. A modest increase in detectable vegetation cover was also observed, …

Research outputs 2022 to 2026

Intrinsic capacity (IC) is defined as the composite of physical and mental abilities an individual possesses, encompassing 5 domains: cognition, psychological health, sensory function, vitality, and locomotion. This construct is central to the World Health Organization’s framework for assessing functional ability in older adults. Growing evidence highlights the critical role of the musculoskeletal system in maintaining these domains, while conditions such as sarcopenia, osteoporosis, and their coexistence as osteosarcopenia (OS) are increasingly associated with IC decline. This narrative review compiles current evidence on the modulatory role of muscles and bones in IC and the impacts of sarcopenia, osteoporosis, and OS. …

The Effect Of Boosting Dietary Lactobacillus And Phytochemical Rich Foods On Biomarkers Of Longevity—A Phase Ii Randomised Placebo Controlled Trial, Robert J. Thomas, Madeleine Williams, Jeffrey W.F. Aldous, Stacey A. Kenfield, Robert U. Newton

Research outputs 2022 to 2026

As men age, systemic inflammation increases, whereas grip strength (GS) and testosterone levels tend to fall. This rate of decline is known to be influenced by gut microbial health, lifestyle and diet but the role for interventions to slow this decline are less well established. This double-blind randomised controlled trial evaluated the impact, and explored the synergistic potential, of boosting phytochemical rich foods and Lactobacillus probiotics on these physical and biological markers. Two hundred and eight men with untreated early prostate cancer managed with observation only (average age 74 years) received a phytochemical rich supplement (PRS) containing concentrated broccoli, green …

Algorithmic Tax Ownership, Young Ran (Christine) Kim, Dmitry Erokhin

Articles

Tax ownership is a crucial concept for determining tax liabilities, compliance, and enforcement. However, neither the courts nor the IRS has provided clear guidance on how to analyze it. Since the Supreme Court first outlined a twenty-six-factor test for determining tax ownership in Frank Lyon Co. v. United States in 1978, this multifactor test has remained largely unchanged, and there has been no further guidance from the courts or the IRS to this day. Even tests with shorter lists of factors only add to the confusion regarding compliance and enforcement, as there is no clarity on which factors are most …

Repurposing Electrical Waste Materials For Developing Corrosion-Resistant Medium Entropy Alloys, Iman El-Mahallawi, Shaza Raji Eng, Shimaa El-Hadad Prof., Mahmoud Tash Prof., Lamiaa Zaki Dr.

Mechanical Engineering

Reusing electrical waste as a sustainable metal source is a promising approach for producing next-generation alloys. In this work, vacuum arc melting (VAM) was used to produce three aluminum-based medium-entropy alloys (AlCuFeCrSi MEAs) from recycled electrical waste. The alloys contained Al in the range 36-46%; Cu in the range 28-35%; Fe in the range 11-18%; Cr in the range 5-6%; and Si in the range 3-6%, with variations in elemental composition resulting from the use of different recovered electrical waste components. Their corrosion performance was evaluated at room temperature, in a 3.5% NaCl solution with and without 1 g/L Mn …

On The Right To Obscurity, Woodrow Hartzog, Evan Selinger

Faculty Scholarship

Tragically, U.S. privacy law has neglected to address a significant dimension of privacy. While lawmakers and judges have routinely recognized intrusions into our secluded spaces and breaches of our confidentiality and secrecy, they have largely failed to protect our most common yet also our most underappreciated form of privacy: the practical obscurity that allows us to live freely and with dignity. Obscurity, which is the state of protection that arises when personal information is difficult for some people to obtain or correctly interpret, serves several vital interests: (1) it safeguards our ability to express ourselves without fear that everything we …

Golden Hour Open Conceptual Architecture For Citizen-Initiated Structured Urgency Signaling, Jaime Gerardo Figoni Him

Defensive Publications Series

Abstract Golden Hour proposes a minimalist, open, and low-bandwidth emergency signaling architecture that enables any citizen to transmit structured urgency information during the critical first hour (“Golden Hour”) of a disaster. The system combines a single-tap severity code (Red / Yellow / Green), a brief guided question sequence, and resilient transmission paths (including SMS/USSD fallback) to generate a live, color-coded situational heat map for emergency responders.

By treating emergency response as a problem of controlling informational entropy, Golden Hour enables a near-instantaneous reduction in chaos while fostering voluntary human solidarity. It is designed as a supplement to — not a …

Electronic Device Placement Via Three-Dimensional Space Reconstruction, Ruofei Du, Mahdi Tayarani Najaran

Defensive Publications Series

Difficulties are encountered when determining placements for electronic devices to ensure coverage of a physical space. A framework for visualizing coverage and suggesting device quantities through three-dimensional space reconstruction is described. Live camera and depth data from portable electronic devices are utilized to generate a digital representation of an environment. A transformer-based neural network is employed to determine device poses and quantities based on the reconstructed space and semantic attributes. Coverage areas, areas without coverage, and unmonitored hazard zones are depicted in real-time, maintaining alignment as a device is physically reoriented. A data-driven approach for deploying equipment such as cameras, …

Set Lists For Conversations On Necropolitics, Antiblackness, And Colonialism, Noah Morton

Black Educology Mixtape "Journal"

In lieu of a traditional syllabus, the following setlist uses the form of an academic syllabus to unsettle ideas around knowledge production and includes six sets with multimodal resources (films, songs, articles) to engage conversations on necropolitics, antiblackness, and colonialism. The setlists come from engaging in genealogies of resistance and liberation and are attentive to recognizing (re – again | cogn – to know | ize – to make) and acknowledging various technologies of domination while witnessing anachoreographies, or spirits of refusal. Each setlist flows from a check-in song, continues to the main set of readings/videos/podcasts, and ends with an …

“Hip-Hop Permeates Everything I Do:” The Intersections Of Global Politics, Hip-Hop, And Education, Mecedes Lindsay

Black Educology Mixtape "Journal"

This qualitative study examines how the absence of Critical Hip-Hop Pedagogy (CHHP) within academic institutions shapes students’ sense of belonging, motivation, and engagement by regulating which forms of cultural capital are deemed legitimate. Drawing on semi-structured interviews and focus groups with students, educators, scholars, and members of the hip-hop generation, this research adopts an interpretivist framework to center participants’ lived experiences within educational spaces. Informed by Freirean critical pedagogy and Yosso’s theory of community cultural wealth, the study situates schooling as a site where America’s soft power operates through curriculum design, disciplinary norms, and definitions of deviance. Findings reveal that …

Purposefully Black Interactional Systems: Disrupting Punitive School Discipline Models Through Banter, The Funk, And The Black Aesthetic, S. M. Wilson

Black Educology Mixtape "Journal"

This empirical study seeks to understand the narratives of four Black men teachers and two Black women teachers about how they implement school discipline and classroom management in their K–12 contexts. This track draws on interdisciplinary perspectives from education, linguistic anthropology, and African American studies to understand how banter and ritual insults function as alternatives to traditional discipline. Phenomenology and thematic analysis of six semistructured interviews demonstrated Black teachers’ beliefs that outdated and punitive orientations should be challenged. These teachers enacted discipline through talk—particularly banter, ritual insults, and what I call “purposefully Black interactional systems,” which embed discipline within them, …

Remixing The Academy Through Backyard Spaces: The Making Of Black Educology, The Mixtape, Dre Carter, Eghosa Obaizamomwan-Hamilton

Black Educology Mixtape "Journal"

As Black academics, researchers, and educators, we navigate the twin topographies of the academy and the open territories of possibility. Connecting these realms, we construct “backyard project” spaces—semi-enclosed areas linking academic spaces and liberated spaces. We use our creation of the backyard as a locality wherein we challenge oppressive, antiquated academic systems and anti-Blackness without waiting for reform. For example, our collective project, the Black Educology Mixtape “Journal,” exemplifies this concept. This track discusses the “backyard” as an extension of both third and fugitive spaces and, through material culture and fugitivity as method, highlights the backyard as a site for …

So Great A Cloud Of Witnesses: A Critical Race Counterstory On Teacher Preparation And Repair, La Mont Terry

Black Educology Mixtape "Journal"

Selective liberal arts colleges (SLACs) are traditionally undergraduate institutions that focus on providing a broad education in the arts, sciences, and humanities rather than the professional training for the workforce typically available at other institutions of higher education. Despite their comprehensive curriculum, many SLACs have a decades-long commitment to teacher preparation as recognition of the connected nature of K–12 schooling and higher education. This track examines the closure of one such teacher preparation program at an urban liberal arts college and its impact on the faculty who taught in it. Using the critical race theory method of counterstorytelling, I position …

Black Boys And The New Media Mixtape: Ownership, Aspiration, And Hustle In A Digital Age, Kareem Edouard, Taquan S. Stewart

Black Educology Mixtape "Journal"

In this track, we explore how “new media” platforms become modern “mixtape” tools for Black boys to remix identity and cultural narratives in the digital age. As Audre Lorde reminded us, “The master’s tools will never dismantle the master’s house.” Still, we aim to interrogate whether these tools can be repurposed for empowerment. This framework unfolds in three parts: examining ownership and the gatekeeping of cultural narratives, exploring how new media platforms shape aspirations and identities for Black boys, and identifying the tools and pathways for Black boys to both see themselves as creators and access content that reflects them. …

Embodied Archives: The Body As Technology Of Black Sustainability, Felicia Rutledge

Black Educology Mixtape "Journal"

This track develops the concept of embodied archives as technologies of Black sustainability in apocalyptic times. Building from Diana Taylor’s distinction between the archive and the repertoire, and in conversation with Hortense Spillers, Saidiya Hartman, Christina Sharpe, Sami Schalk, Tiffani Marie and Kenjus Watson, and Ruha Benjamin, I argue that Black bodies function as living repositories of knowledge. Long before schools claimed authority over learning, communities preserved memory in movement, rhythm, oral and signed languages, tactile practices, and everyday rituals of care. Disabled Black bodyminds, through practices such as braille literacy and augmentative and alternative communication, further illustrate how assistive …

Dancing In The Wake | Like Moss Over Modernity, Simple Ant

Black Educology Mixtape "Journal"

This offering is a meditation on existing and thriving in the wake of civilization. For centuries, we have educated one another to believe in, and glorify, the insatiable desires of our modern way of life. I begin with the premise that what we call “civilization” is a system predicated on death, violence, and exploitation, because it requires the endless extraction and consumption of the living Earth. Living in this way guts the Earth to feed our ideas of “progress” and “prosperity.” The effect now is that our civilization, our society, our way of life is rotting—bringing with it decay and …

Materials and methods: Fifty-six women (mean age 47 ± 8 years) were randomly assigned (1:1) to a HIIT group or a control group (CG). Thirty-five participants were included in analyses (HIIT group = 17; CG = 18). HIIT group performed 4 × 4-minute HIIT sessions at the intensity of 85–95% of the peak heart rate, two to three …

Ibn Battuta's New Journey And Crossing The Boundaries Of The Semiosphere, Abdelhafid Mechkouri

SOROUD: The journal of Literacy Criticism

This article addresses the symbolic semiotic representations expressed in Ibn Battuta's New Journey, focusing on cultural space in relation to the self, the traveler, and the other. Drawing on Yuri Lotman's theory of the semiosphere, the study examines how the traveler-narrator moves within the Islamic semiosphere and across neighboring cultural spaces. It shows that cultural representations are organized around three major oppositions: similarity and difference, us and them, and the sacred and the profane. The article argues that the journey divides the other into internal and external figures and organizes space into familiar, safe, and sacred zones on the one …

Shrinking Sovereignty: By Land, Sea, And…Air?, Cynthia R. Harris

Pace Environmental Law Review

Atlantis was a mythical State destroyed by the gods as an object lesson to humanity. The complete destruction of a State, as a political entity, does have precedent in historical reality. The complete and permanent loss of a State’s physical territory, however, is a problem humanity has never faced—until now. Today, climate change-driven sea level rise is bringing the future sovereign status of Small Island Developing States (SIDS) in question. A growing body of legal scholarship argues for maintaining these States’ maritime jurisdictions but has not yet extended the question skyward to SIDS’ jurisdiction over airspace.

This Article addresses that …

Municipality Of Bayamón V. Exxon Mobil Corp. (2025): Bringing Racketeering Charges For Climate Justice, Ilinca C. Johnson

Pace Environmental Law Review

Environmental justice communities should have their climate change damages heard in the courtroom. One means to increase environmental justice claims is through claims under the federal Racketeer Influence and Corrupt Organizations (RICO) Act. Using Municipality of Bayamón v. Exxon Mobil Corp. (2025) as a model, this Article suggests a novel RICO case strategy to pursue climate damages for marginalized communities. Fundamentally, environmental justice RICO claims involve careful case design based on the climate-related damages a marginalized community has faced because of the long-term deception by fossil fuel actors upon those communities. Pursuing such claims forwards the intersectional issues faced by …

Enhancing Emergency Preparedness In California High Schools: A Policy Framework For Implementing Nata-Compliant Emergency Action Plans Through Multidisciplinary Task Forces, Jennifer Lu

Doctor of Nursing Practice Final Manuscripts

Abstract

Background: Sudden cardiac arrest (SCA) is the leading cause of death in young athletes, yet it is highly survival with proven measures: a structured emergency action plan (EAP), cardiopulmonary resuscitation (CPR) training, and access to an automated external defibrillator (AED) within 3 minutes can raise survival rates to 90%. Despite this, high schools show inconsistent compliance, largely due to the lack of fragmented oversight and lack of standardized practices

Purpose of Project: This proposal advocates for multidisciplinary task forces to enforce venue-specific, National Athletic Trainers Association (NATA)-compliant EAPs across California high schools, with the goal of improving emergency response …
