Hybrid Deep (Cnn-Bilstm) Intrusion Detection For Defense And Mission-Critical Networks, Corey A Cheng, Jermaine Anim-Addo, Asma Jakir Hussain, Zion O Smith-Fox, Sanjay Goel, Yuksel Celik

Military Cyber Affairs

This article examines how hybrid deep learning can strengthen intrusion detection for military and defense networks. Using the CSE-CIC-IDS2018 dataset, the study evaluates a CNN-BiLSTM model designed to detect benign traffic and multiple attack categories, including DDoS, DoS, botnet, brute-force, web attack, and infiltration activity. The model achieved strong multi-class detection performance, with 0.9893 accuracy and 0.9979 ROC-AUC. The findings suggest that AI-supported intrusion detection can improve cyber defense operations, analyst triage, and protection of mission-critical networks.

Reinterpreting The Grand Ethiopian Renaissance Dam Dispute In The Nile Basin Through The Game Theories Of Attrition And Bargaining, Olileanya Amuche Ezugwu, Felix C. Chidozie, Adeola A. Adebajo

Journal of Strategic Security

Why have more than a decade of negotiations, mediation efforts, and diplomatic interventions failed to produce a binding agreement on the Grand Ethiopian Renaissance Dam (GERD)? This article examines the hydro-politics of the Nile Basin through the lens of game theory, focusing on how bargaining behavior, strategic persistence, and competing perceptions of gains and losses shape state interactions. Drawing on the game of attrition and the bargaining game, the study analyzes the evolving strategies of Ethiopia, Egypt, and Sudan in the context of dam construction, filling, and operation. Rather than viewing the dispute solely as a contest over water allocation, …

OneUSF Summer Undergraduate Research Symposium

Music can be defined as structured sound that serves as a “universal language” capable of influencing emotion, cognition, and social connectivity in humans. Its formal application into the medical profession began in the 20th century, following World War I and II.  Human subject research involving music therapy has since reported a myriad of health benefits such as those on emotional (e.g., anxiety, depression, and stress), neurological (e.g., cognitive impairment, sleep issues, and dementia), and physical well-being (e.g., pain, multiple sclerosis, fibromyalgia). However, the impact of such structured acoustics on biological processes at the cellular and molecular level remains unclear. Towards …

Conserving Seabirds: Actions Of The Pacific Seabird Group During Its First 40 Years., Craig S. Harrison

Marine Ornithology

The Pacific Seabird Group (PSG), founded in 1972, is “dedicated to the study and conservation of Pacific seabirds and their environment.” During its first 40 years, PSG undertook scores of conservation actions, although as an all-volunteer organization, PSG lacked the capacity to implement many programs or projects. It achieved its conservation goals through leadership, raising issues, bringing the best science to decision makers, and serving as a catalyst for others to act. PSG has been especially influential in six areas: (1) eradicating invasive alien animals from seabird colonies; (2) conserving Marbled Murrelets Brachyramphus marmoratus; (3) protecting seabird colonies in …

Marine Ornithology

We provide, for the first time, data on the breeding parameters of the Gull-billed Tern Gelochelidon nilotica in Tunisia, at Boughrara Lagoon. From May to July 2024, we monitored a breeding colony located on a small islet in the northern part of the lagoon. In total, 112 nests were monitored: 71 nests initiated in mid-May (early clutches) and 41 in early June (late nests). Clutch size ranged from one to four eggs (mean ± standard deviation [SD] = 2.51 ± 0.06), with no significant difference between early and late nesters. Egg volume ranged from 14.65 to 49.23 cm3 (mean ± …

Sex And Age Characteristics Of Northern Fulmars Fulmarus Glacialis Used In Programs To Monitor Plastic Ingestion., Jan A. Van Franeker, Susanne Kühn

Marine Ornithology

Carcasses of beached or accidentally killed Northern Fulmars Fulmarus glacialis, collected for monitoring plastic ingestion, have shown that the incidence of litter may vary over time and by region. Age, sex, and season of fulmar collection appear to affect the quantity of plastics ingested. More detailed analyses of monitoring data thus require reliable and consistent methods for assessing age and sex. Methods were first described in a monitoring manual in 2004 and later in international guidelines, but age and sex definition required further clarification. A large dataset of 3,790 dissected birds now allows for detailed descriptions of sex and …

Seabirds As Ecosystem Engineers: Providing Arthropod Habitat On Oceanic Islands., Kanon Mizukoshi, Kazuto Kawakami, Takashi Kamijo

Marine Ornithology

Seabirds play several important ecological roles on oceanic islands through their high-density breeding. Their ecosystem functions—such as nutrient cycling through excretion or terrestrial vegetation disturbance through trampling—are well known; however, little is known of their roles as ecosystem engineers. Nests and burrows can be densely concentrated in seabird colonies, by which seabirds can affect adjacent terrestrial ecosystems, especially affecting arthropods that use these structures as food or habitats. However, studies investigating the species composition of arthropods that inhabit seabird nests are limited. To characterize the arthropod faunas in seabird nests, this study surveyed and analyzed 90 nests of three seabird …

Comparing Counts Made From Drone-Based And Boat-Based Photography For Surveying Thick-Billed Murre Uria Lomvia Cliff Colonies., Ewan Macdonnell, Sarah E. Gutowsky, Kyle H. Elliott

Marine Ornithology

Surveys of cliff-nesting seabirds from sea level or ground level often miss individuals hidden by topography, leading to underestimates of abundance. Thick-billed Murres Uria lomvia are especially challenging to survey accurately due to their dense nesting on vertical cliff ledges in remote northern regions. In Canada, updated colony surveys are needed, as currently used population estimates, done from boats, are outdated. Drones offer better vantage points and may reduce availability bias (i.e., the proportion of birds present but not visible), but direct comparisons with boat-based counts are essential. We compared murre counts from drone- and boat-based photographs of six vertical …

Foraging Areas Of Breeding Adult Sooty Terns Onychoprion Fuscatus On Bird Island, Seychelles., Jessica L. Neumann, Ruth E. Dunn, Malcolm A. C. Nicoll, Christine S. Larose, Chris Foster, Gary Brodin, Chris J. Feare

Marine Ornithology

The foraging areas used by adult Sooty Terns Onychoprion fuscatus during incubation and early chick-rearing on Bird Island, Seychelles, were investigated using small GPS loggers. Birds departed the colony mainly during the night and foraged by day. Most foraging trips were completed within 24 hr, but during incubation the longest duration recorded was seven days and 14 hr (during which the bird travelled 2,783 km and reached a maximum of 692 km from the colony). Departures were generally in an arc from south (180°) through westerly to 40°. Sooty Terns foraged frequently in waters over the Seychelles Bank shelf break, …

Predicting Suitable Marine Habitat For Pink-Footed Shearwaters Ardenna Creatopus In The Waters Along The Pacific Coast Of Canada., Sonya A. Pastran, Patrick D. O’Hara, Kenneth H. Morgan, Caroline H. Fox, W. Eric Gross

Marine Ornithology

Anthropogenic activities are threatening global marine ecosystems, with seabirds representing a vulnerable group that has experienced pronounced population declines in recent decades. The ability to identify important marine areas for vulnerable seabirds is fundamental to conservation initiatives. The Pink-footed Shearwater Ardenna creatopus (listed as Endangered in Canada) breeds only in Chile, but during the non-breeding season, it ranges northward to waters off Canada's Pacific coast and the northern Gulf of Alaska. Using at-sea survey data spanning from 1992 to 2019, we examined the relationship between the species' distribution and environmental variables using a two-step generalized additive model approach. Cross-validation with …

Tasmanian Records Of Vagrant Penguins, 1991–2025., Eric J. Woehler

Marine Ornithology

During the period 01 January 1991 to 31 August 2025, there were 274 records of vagrant penguins in Tasmania. These records represented three genera: Aptenodytes, Pygoscelis, and Eudyptes. The most frequently reported species were Fiordland Penguin E. pachyrhynchus, Royal Penguin E. schlegeli, and King Penguin A. patagonicus. High numbers of records were reported from 10 years, with a peak in 1999 and a lower peak in 2023. Records from January to March accounted for approximately 42% of all vagrant penguin occurrences and corresponded with the arrival of pre-moult birds of all ages. A range …

Evidence For Colony Attendance By Immature Streaked Shearwaters Calonectris Leucomelas During The Chick-Rearing Period., Helen M. Pružina, Akiko Shoji, Masaki Shirai, Sakiko Matsumoto, Ken Yoda, Annette L. Fayet

Marine Ornithology

Many seabird species have a long breeding-deferral period, during which individuals mature and spend most of their time at sea, making them particularly difficult to study. In some species, immatures are known to start visiting colonies before reaching adulthood, presumably to learn the behaviours required to secure a nest and mate for future breeding. However, immature colony attendance remains undocumented in many species, particularly those that are difficult to observe, such as nocturnal, cavity-nesting species and species in which immatures are indistinguishable from adults. Here, we studied the attendance patterns and behaviour of Streaked Shearwaters Calonectris leucomelas on Awashima Island, …

Satellite Tracking Of Galapagos Petrel Pterodroma Phaeopygia Reveals Distribution And Movements During Chick Rearing., Carolina B. Proaño, Sebastian M. Cruz, Josh Adams, Martin Wikelski

Marine Ornithology

We tracked 19 adult Galapagos Petrels Pterodroma phaeopygia during the chick-rearing seasons in 2009 and 2010 (Santa Cruz Island [n = 16] and Floreana Island [n = 3]) in the Galápagos Islands, Ecuador. Eight petrels performed 27 complete foraging trips lasting 0.6 to 18.8 days. Short trips (3.2 ± 2.1 days; 785 km; max displacement 671 km) and long trips (10.8 ± 3.9 days; 2,856 km; max displacement 1,034 km) resulted in concentrated use of waters off southern and western Isabela Island and within the Galápagos Marine Reserve (GMR). Less concentrated time extended farther southwest and eastward, in …

Unfamiliar Plumage Aberration Observed On A Razorbill Alca Torda At Machias Seal Island., Daniel Oliker, Antony W. Diamond, Heather L. Major

Marine Ornithology

Aberrant plumage variation in seabirds can be caused by both heritable genetic mutations and non-heritable somatic mutations due to environmental stressors. In Razorbills Alca torda, aberrant colouration has been documented four times: three as cases of melanism and one seemingly of leucism, both heritable mutations. Here, we describe the observation and subsequent capture of a Razorbill with an unfamiliar plumage phenotype we hypothesize to be caused by a somatic mutation. To our knowledge, this is the first reported instance of a somatic mutation affecting the plumage of a Razorbill in the primary literature.

Seasonal Variation In Trophic Niche And Resource Use In Great Black-Backed Gulls Larus Marinus., Samuel Langlois Lopez, Nina J. O’Hanlon, Jared Wilson, Rona A. R. Mcgill, Francis Daunt, Elizabeth A. Masden

Marine Ornithology

Seabirds experience variable extrinsic and intrinsic pressures throughout the annual cycle that affect their ability to forage. Consequently, their foraging strategies may vary between breeding and non-breeding seasons due to the constraints of central-place foraging during the former. Here, we studied a population of a generalist seabird, the Great Black-backed Gull Larus marinus, breeding at a colony on the Isle of May, Scotland. We quantified seasonal variation in sexual segregation, trophic position, trophic niche width, and resource use by examining stable isotopes in feathers collected from adults. We found no sexual segregation, but we detected population- and individual-level shifts …

Assessing The Impact Of Coordinated Mink Culling On Bird Populations On Coastal Islands In Norway., Fredrik R. Staven, Torgeir Nygård

Marine Ornithology

The introduction of the non-native American Mink Neogale vison (syn. Neovison vison), a predator of birds and their chicks and eggs, is one of many anthropogenic factors that may be driving the decline of seabird populations in areas where mink are prevalent. Previous studies have shown that ground-nesting birds utilising coastal ecosystems are especially vulnerable. In this study, we investigated changes in seabird and coastal-bound bird populations, focusing on ground-nesting species, and the potential effect from mink culling. Ten locations in the archipelago of Flatanger, a coastal municipality in central Norway, were surveyed, and bird counts from 1991, 2016, …

Missed Diagnoses Beyond Endemic Borders: How Knowledge And Resource Access Shape Testing For Cutaneous Leishmaniasis And Chagas Disease, Alyssa Agnew, Brandon Lopez, Cherry Mawii, Erin Aslan, Sreshta Sankar, Semené Clement

OneUSF Undergraduate Research Conference

Cutaneous Leishmaniasis (CL) and Chagas Disease (CD) are both tropical vector borne diseases most common in endemic regions. CL is caused by a parasite spread through sandfly bites. CD is caused by the parasite transmitted through the feces of Triatomine bugs. They are not common in non-endemic regions resulting in lack of training and knowledge required to properly diagnose and treat these diseases. This study assesses how clinician knowledge and access to diagnostic tools influence testing practices for CL and CD in non-endemic regions and contribute to diagnostic bias, underrecognition, and delayed diagnosis.

A comprehensive literature review was performed through …

Leveraging Computer Vision-Based Hand Tracking In Smartphone Xr Exposure Scenarios To Enable Controller-Free Interaction, Alex C. Lim, Trang Nguyen

OneUSF Undergraduate Research Conference

Extended reality (XR) has emerged as an effective and convenient solution for broadening accessibility to exposure therapy. Smartphone-based XR, though cost-effective, is often constrained by limited interactivity, engendering a passive experience that can compromise the user-immersion and treatment efficacy. To address this limitation, this study presents a novel computer vision–based hand-tracking approach using Google MediaPipe, integrated within a stereoscopic smartphone-based XR system to enable real-time, controller-free interaction in a dog-fetch scenario. Hand landmark coordinates derived from MediaPipe are algorithmically adjusted based on changes in inter-knuckle distances during anterior/posterior movement to approximate depth, at which point interactive spheres are overlayed to …

Every year, 2.06 billion Muslims perform Ramadan fasting, a religious practice involving abstinence from food and drink from dawn to sunset for 30 days. This religious practice changes diet, hydration, sleep, and medication timing, raising clinical concerns for the safety of individuals with chronic diseases who choose to fast. Research reports mixed effects on disease control and treatment safety, emphasizing the need for an overarching analysis of its impact on chronic disease management. This literature review is aimed to examine research on Ramadan and intermittent fasting on chronic disease management and to analyze its effects on disease control, clinical outcomes, …

Reproductive Equity: A Comparative Chemical Analysis Of Emerging Male Contraception Technology, Grace Kim, Esmaralda Pilar-Lopez

OneUSF Undergraduate Research Conference

Female oral contraceptives, although abundant in access and successful as contraceptives, pose significant risks to women’s health. Biosocial factors that discourage male contraceptive drugs include harmful hormonal changes and inconsistent efficacy. This research employs comparative analysis of three current methods on potential male contraceptive options, focusing on steroid chemistry, functional group modification, and bioavailability. Emerging male contraceptive drugs of interest include the non-hormonal retinoic acid (vitamin A) receptor to antagonize sperm production, blocking the sperm-specific 〖Ca〗^(+2)  ion channel, and a reversible “Chemical Plug” that limits sperm movement at the vas deferens. Through comparison, this research will use six references to …

Emerging Technology In Leptospirosis Testing: Comparison And Future Directions, Ashley Kassay, Mallory Caldwell

OneUSF Undergraduate Research Conference

Leptospirosis is an under-recognized zoonotic bacterial infection that is responsible for 1 million cases and 60,000 deaths globally every year. With vague symptoms, it is difficult to diagnose in early stages, and if left undiagnosed, it is highly fatal. To prevent late diagnosis, there must be research into improving testing methods, especially with respect to countries with limited resources. The following will compare emerging technologies in leptospirosis testing, such as CRISPR, LAMP, microfluidic-based paper device, and photothermal immunosensing, with traditional testing methods such as MAT and PCR. Comparing biomarkers, sample type and amount, time, sensitivity, point-of-care ability, this research determined …

Gopher Tortoise Burrow Census And Population Estimate In The University Of South Florida Sarasota-Manatee Conservation Area, Anthony J. Richard, Linda Vesser

OneUSF Undergraduate Research Conference

The gopher tortoise (Gopherus polyphemus) is a threatened species in Florida, and both the tortoise and its burrow are protected in their range across the southeastern United States.  The University of South Florida Sarasota-Manatee (USFSM) campus is home to a 6.6-acre conservation area that supports a population of gopher tortoises as well as other native and threatened plant and animal species. As an initial determination of population size, we mapped all current burrow locations using a Garmin GPSMAP 64st.  As tortoises spend most of their time inside their burrows, estimates of population size can be difficult.  However, burrow surveys are …

Testing Downstream Analysis Of Noninvasive Anoa Dna Samples Using The Mm12 Primer, Madisen Hamai

OneUSF Undergraduate Research Conference

The lowland anoa (Bubalus depressicornis) is an endangered species of wild cattle endemic to Sulawesi, Indonesia. As anoa populations are expected to decline in future years, genetic analysis is important to monitor numbers and guide both in situ and ex situ conservation efforts. Because anoa avoid human interaction, noninvasive sampling methods of DNA collection are being tested. These methods minimize stress to the animal and allow scientists to measure genetic diversity within anoa populations and relatedness between individuals.

This study uses PCR amplification of a microsatellite to determine whether noninvasive DNA is suitable for population level analysis. The study uses …
