Noteworthy Natural History Notes From The Neotropics, R. Kannan

Journal of the Arkansas Academy of Science

I report some rarely observed, infrequently reported, or hitherto unrecorded ecological interactions from the neotropics. These anecdotal observations were made opportunistically during nature tours or tropical biology classes in Belize, Panama, Costa Rica, and Trinidad & Tobago, between 2014 and 2024.

Sperm Morphology In The Eastern Narrow-Mouthed Frog, Gastrophryne Carolinensis (Anura: Microhylidae), S. E. Trauth

Journal of the Arkansas Academy of Science

Studies by Scheltinga et al. (2002) and Scheltinga and Jamieson (2003) provide the most comprehensive analysis and only review of sperm morphology in Narrow-Mouthed Frogs (family Microhylidae). Of the 490+ species known to occur in this anuran family (Vitt and Caldwell 2014), only 3 are distributed in the United States (Powell et al. 2016), and 2 of these occur in Arkansas (Trauth et al. 2004). Surprisingly, sperm studies on only 12 microhylid species have been conducted (Scheltinga and Jamieson 2003), and no sperm studies are available on any North American species.

Investigating Quinclorac Binding To Human Serum Albumin Using Spectroscopy And Molecular Docking, Le Nguyen, L. Hicks, L. Jodoin, S. Carby, D. S. Sanford, D. Benavides, A. Mishra, R. Yadav

Journal of the Arkansas Academy of Science

Human serum albumin (HSA) is the most abundant plasma protein and serves as a major transporter and reservoir for a wide range of endogenous ligands, including fatty acids, heme, bilirubin, prostaglandins, and metal ions, as well as numerous exogenous compounds, such as pharmaceuticals. HSA is a 66 kDa monomeric, multidomain protein containing two principal ligand-binding sites, Sudlow sites I and II. Sudlow site I contains Trp214, the sole tryptophan residue in HSA, whose intrinsic fluorescence provides a sensitive probe for studying ligand–protein interactions.

In this study, the interaction between HSA and the persistent organochlorine herbicide quinclorac (QNC) was investigated using …

History And Distribution Of The Dark Ibises (Glossy Ibis Plegadis Falcinellus And White-Faced Ibis P. Chihi) In Arkansas, R. Tumlison, P. D. Rodriguez

Journal of the Arkansas Academy of Science

The Glossy Ibis (Plegadis falcinellus) and White-faced Ibis (P. chihi) sometimes are reported simply as Dark Ibises due to difficulty in identifying them when mature characters are not clearly visible. We evaluated reports verified on citizen science websites to examine the origins and distributions of these migratory species in Arkansas. The Glossy Ibis was first documented in Arkansas in 1956, has been reported in 21 of our 75 counties, and is found more commonly in eastern Arkansas. The White-faced Ibis was first reported in Arkansas in 1971, has been reported in 41 of our 75 counties, …

History And Distribution Of Great-Tailed Grackles (Quiscalus Mexicanus) In Arkansas, R. Tumlison, V. Andersen

Journal of the Arkansas Academy of Science

Great-tailed Grackles (Quiscalus mexicanus) were reported first in southwestern Arkansas in 1969, were nesting there in 1977, and established a resident population by 1980. Nesting was reported in far northwestern Arkansas in 1986. Presently, the species is known from 44 of Arkansas’s 75 counties, those mostly in the western and central counties. Most individuals appear to be migratory, with most reports occurring in April and May. However, breeding and now resident populations have been reported in the southwestern, northwestern, and central counties, particularly in urban areas. Birds are very commonly reported to forage at fast-food establishments and truck …

This research investigated the multifaceted experiences of teenage mothers within BLISTT (Baguio, La Trinidad, Itogon, Sablan, Tuba, Tublay), where adolescent pregnancy remains a persistent social and public health concern. The study highlighted how these young mothers navigated interrupted education, limited economic opportunities, and fragile family relationships, all compounded by cultural stigmas and a lack of reproductive health education. The core research questions explored the lived experiences of these teenagers, the influence of cultural beliefs on societal attitudes, and the challenges and support systems that shaped their lives and futures. Findings revealed that teen mothers within BLISTT faced profound emotional, social, …

A Scoping Review Of Sycophancy In Large Language Models: Operational And Theoretical Recognition, Kallen Zhou, Manning Littlejohn, Isabella Garrard

Endeavors: Mississippi State Undergraduate Research Journal

As large language models (LLMs) usage grows across different domains, sycophancy, the tendency for output to align with users, is increasingly being recognized as a primary issue arising from applying LLMs into critical areas. Current research has provided a variety of theoretical definitions, mitigation techniques, and quantification for sycophancy. However, there is little to no consistency across different papers. This scoping review seeks to connect different works on LLM sycophancy by identifying themes in theoretical definitions, measurement methods, and inducement techniques of sycophancy. By analyzing 26 papers (preprints, conference proceedings, and journal articles) from arXiv, ACL Anthology, and Scopus, this …

Near-Infrared Spectroscopy For Monitoring Bovine Respiratory Syncytial Virus Infection In Experimentally Challenged Calves, Erin Blanchard, Jelena Muncan, Grace Beddingfield, Cassandra Barber, Florencia Meyer, Santiago Cornejo, Merrilee Thoresen, Amelia Woolums, Carrie Vance

Endeavors: Mississippi State Undergraduate Research Journal

Bovine respiratory disease (BRD) is a multifactorial disease complex that causes significant economic loss in the cattle industry. Bovine respiratory syncytial virus (BRSV), one of the primary viruses included in BRD, primarily targets the lower respiratory tract and causes a wide variety of subclinical and clinical signs. Current diagnosis techniques require off-site laboratory testing, creating delays that allow BRSV to spread through herds and highlighting the need for rapid diagnostic methods. The objective of the study was to evaluate near-infrared spectroscopy as a diagnostic tool for BRSV detection across varying infection severities. Twenty-two Holstein bull calves were reared in research …

‘It’S A Win-Win Situation’— Cultivating University & School Partnerships, Emily Wisniewski, Kelly Virgin, Pauline Skowron Schmidt

Teaching/Writing: The Journal of Writing Teacher Education

This qualitative case study examines Writing Zones, a fifteen-year university–high school partnership that embeds preservice English teachers in secondary classrooms as writing mentors. Drawing on surveys from 20 preservice teachers and eight high school teachers, along with follow-up interviews, the study explores perceptions of preparation, support, and program impact. Findings highlight Writing Zones as a mutually beneficial model that enhances student writing through individualized support while providing authentic, field-based learning for preservice teachers. However, effectiveness was conditional, shaped by mentor preparedness, clarity of roles, communication, and scheduling. The study underscores the importance of intentional training, sustained relationships, and institutional alignment …

Dismantling Future Writing Teachers’ English-Only Assumptions: Composing Videos To Learn The Value Of Linguistic And Cultural Inclusion, Ann N. Amicucci

Teaching/Writing: The Journal of Writing Teacher Education

This article presents the results of a study of 12 students’ video composing assignments and accompanying reflections in which students, all of whom were future writing teachers enrolled in an undergraduate TESOL course, examined how well public spaces acknowledged and included multilingual individuals. Students’ videos and reflections demonstrated that the assignment dismantled these future writing teachers’ assumptions that multilingual writers learn best in an English-only environment but perpetuated perceptions of languages as discrete rather than intertwined. Findings are discussed within the context of scholarship on writing teacher education and English-only policy and practice in the U.S.

A3) Reconstructing Sacredness In The Digital Age: Mobile Digital Sacred Spaces And Transformative Experiences In Heritage, Dong Wang, Silvia Gili Aulet

International Religious Tourism and Pilgrimage Conferences

This study explores the reconstruction of sacredness and cultural meaning in digital immersive experiences at religious heritage sites. Traditional sacredness is rooted in physical space and material authenticity, while the Longmen Grottoes (a UNESCO World Heritage Site and important Buddhist destination in China) is accelerating digital transformation through mobile-based digital incense offerings, algorithmic "Buddha affinity" matching and digital twin visualization platforms, breaking the classical ontology of fixed sacred space.

Based on the Stimulus-Organism-Response (S-O-R) model, this study defines digital atmosphere, narrative engagement and interactive rituality as external stimuli, "digital sacredness" a second-order internal psychological state encompassing transcendence, awe, serenity and …

Cognitive Autonomy In The Age Of Ai: A First-Year University Writing Teacher’S Case For Embodied Learning, Rachel M. Terry

Essays in Education

Cognitive autonomy in the age of AI is becoming an urgent concern in higher education. This article argues that first-year writing instruction should recover cognitive autonomy and embodied learning as correctives to technocratic habits shaped by generative AI, digital convenience, and an overreliance on optimization. Drawing on the author’s positionality as a first-year university writing teacher, it examines how students increasingly treat knowledge as detachable information rather than as something formed through disciplined engagement. The article includes examples of handwritten note-taking and annotation as embodied learning that slows thought, deepens synthesis, and supports student agency. It concludes that education should …

Generalized Delayed Black–Scholes Formula, Bi Gole Hubert Le, Auguste Aman

Journal of Stochastic Analysis

The aim of this paper is to derive an explicit pricing formula for European options when the underlying asset follows a linear generalized delay differential equation in two distinct financial markets. The pricing methodology is based on the construction of an equivalent martingale measure using Girsanov’s theorem. Our models preserve both the no-arbitrage condition and market completeness. As such, this work extends the framework previously developed by Arriojas et al. in [16], providing a broader class of delay-based option pricing models.

Robust Optimal Consumption, Investment And Reinsurance For Recursive Preferences, Elizabeth Dadzie, Wilfried Kuissi Kamdem, Marcel Ndengo

Journal of Stochastic Analysis

This paper investigates a robust optimal consumption, investment, and reinsurance problem for an insurer with Epstein-Zin recursive preferences operating under model uncertainty. The insurer’s surplus follows the diffusion approximation of the Cramér-Lundberg model, and the insurer can purchase proportional reinsurance. Model ambiguity is characterised by a class of equivalent probability measures, and the insurer, being ambiguity-averse, aims to maximise utility under the worst-case scenario. By solving the associated coupled forward-backward stochastic differential equation (FBSDE), we derive closed-form solutions for the optimal strategies and the value function. Our analysis reveals how ambiguity aversion, risk aversion, and the elasticity of intertemporal substitution …

An Itô Integral For A Two-Sided Lévy Process, Raluca Balan, Jaime Garza

Journal of Stochastic Analysis

In this article, we construct an Itô integral with respect to a two-sided finite-variance Lévy process {L(x)}x∈R, without a Gaussian component. Using Rosenthal inequality for discrete-time martingales, we give an estimate for the p-th moment of this integral, for any even integer p ≥ 2. Then, using Poisson-Malliavin calculus, we show that the Itô integral is an extension of the Hitsuda-Skorokhod integral with respect to the compensated Poisson random measure associated to the Lévy process.

Dynamic Context‑Aware Tokenization For Intent‑Driven Agent‑To‑Agent Transactions, Chandra Shekhar Matam, Harshwardhan Tripathi, Nancy Lakra

Defensive Publications Series

The present disclosure relates to a dynamic tokenization system for facilitating intent-driven transactions between autonomous agents. The system includes a context-aware token that encodes metadata defining multiple conditional spending profiles associated with distinct transaction intents. An intent declaration module receives specified transaction intents from the initiating autonomous agent, while a policy engine evaluates the declared transaction intent along with contextual factors such as agent identity and historical transaction behavior. A dynamic parameterization mechanism updates the metadata of the context-aware token in real-time, establishing context-specific limits on spending, merchant restrictions, transaction velocity, and expiration rules. During authorization, an authorization network validates …

Eyewear-Integrated Hardware-Enclaved Sensor Gating Interface Utilizing Asynchronous Data Valving And Biomechanical Intent Verification, Daitona Carter

Defensive Publications Series

This disclosure details a physical, hardware-enclaved security architecture designed to prevent unauthorized, passive audio and visual data extraction from wearable computing platforms. The framework mechanically decouples micro-electromechanical systems (MEMS) microphone arrays and camera sensors from the primary application processor (AP) and host operating system. Raw environmental data streams are routed exclusively into a hardware-isolated, bare-metal secondary microcontroller core operating a dedicated, secure execution environment. This secondary core controls an asynchronous data valve: raw sensor inputs are buffered in a one-way FIFO queue completely inaccessible to the host processor unless explicitly released by a verified user intent signal. This physical intent …

The system uses client-side RF environment auditing to calculate signal strength anomalies via the Inverse-Square Law, alongside a logical framework that locks location attestation to an active, cryptographically signed PSTN call session token. Unauthenticated backend queries are dropped at the firmware level.

Automated Emulation Of Life Cycle States And Configuration Fuses, Rohit Sinha, Afshin Hosseinipour, Kyle Rupnow, Janardan Prasad, Rama Thotakura

Defensive Publications Series

System-on-Chip devices often use One-Time-Programmable (OTP) fuses to maintain permanent configuration data, including manufacturing life cycle states and security provisioning. Because programming these physical fuses is an irreversible process, manufacturers frequently delay the testing of end-user features that rely on final fuse states until the concluding stages of manufacturing. Such delayed testing may result in late-stage defect discovery, additional hardware revisions, and longer debugging efforts. The disclosed hardware architecture facilitates the dynamic, non-destructive emulation of configuration fuse states. By employing a multiplexing unit and dedicated control logic, the hardware architecture selectively routes customizable configuration data from a volatile internal memory …

Multi‑Scan Enable (Mse) Hybrid Methodology For At‑Speed Transition Delay Fault Testing, Vevekanenda Gonugunta, Ankit Garg, Vipin Kakkatt, Aravinda Acharya

Defensive Publications Series

Test engineers utilize at‑speed transition delay fault testing to maintain product quality in sub‑nanometer semiconductor designs. The standard launch‑on‑capture (LOC) methodology may face controllability limitations due to functional logic dependencies. These dependencies may prevent the testing system from activating targeted transitions, which might lead to test escapes. While alternative methods (e.g., launch‑on‑shift (LOS), control test points) exist, these alternative methods may introduce timing closure challenges or performance degradation in high‑frequency circuits. This disclosure describes a hybrid methodology utilizing localized multi‑scan enable (MSE) generator logic. A testing system temporarily enables a localized shift mode on specific launch flip‑flops to transform sequential …
