Scaling Of Buccal Mass Growth And Muscle Activation Determine The Duration Of Feeding Behaviours In The Marine Mollusc Aplysia Californica, Jeffery P. Gill, Anna Skalski De Campos, Katherine X. Wang, Isha V. Kaza, Victoria X. Fan, Hillel J. Chiel

Faculty Scholarship

The mechanical forces experienced during movement and the time constants of muscle activation are important determinants of the durations of behaviours, which may both be affected by size-dependent scaling. The mechanics of slow movements in small animals are dominated by elastic forces and are thus quasistatic (i.e. always near mechanical equilibrium). Muscular forces producing movement and elastic forces resisting movement should scale identically (proportional to mass^2/3), leaving the scaling of the time constant of muscle activation to play a critical role in determining behavioural duration. We tested this hypothesis by measuring the duration of feeding behaviours in the …

Grazing On The Arizona Strip: Catchment History And Repair, Melanie Heaton

All Current Publications

Water, not forage, is the limiting factor for wildlife and livestock grazing the Arizona Strip, a nearly 3-million-acre piece of land located north of the Grand Canyon and south of the Utah border. Since springs and groundwater are rare or absent, harvesting of natural precipitation is the main source of water for animals. Catchment systems, which capture precipitation on a sloped rubber apron and contain it in a large tank or lined pond, are used by government agencies and grazing permittees to efficiently provide water for wildlife and livestock. As catchments reach the end of their useful lives, tank replacement …

Psychology Faculty Publications

Functional analysis methods allow clinicians to determine the variable(s) that maintain destructive behavior. Previous reviews of functional analysis outcomes have included large samples of published and unpublished datasets (i.e., clinical samples). The purpose of this review was to conduct a large retrospective consecutive controlled case series of clinical functional analyses. We sought to identify the prevalence of differentiation, procedural modifications for undifferentiated and differentiated cases, and identified function(s) of destructive behavior. In addition, we extended the existing literature by determining whether functional analysis differentiation and function varied when single or multiple behavior topographies were consequated in the functional analysis.

Relationship Between Knowledge, Years Of Licensure, And Attitudes Of Midwives About Female Genital Mutilation And Its Prevalence Among Their Patients In Bawku, Ghana, Frank Debrah

Walden Dissertations and Doctoral Studies

Female genital mutilation (FGM) is one of the hindrances to girls' development. FGM is often a rite of passage between childhood and adulthood. This cross-sectional study examined the relationship between the knowledge, years of licensure, and attitudes of midwives regarding FGM and the prevalence of FGM among their patients in Bawku, Ghana. Bronfenbrenner's social ecological model served as the theoretical framework to describe the link between midwives' knowledge, attitude, years of licensure, and FGM prevalence. The knowledge and attitude of midwives were classified as exosystem factors. Hence, their direct interaction with patients is likely to affect the patient's practice of …

Teaching "Is This Case Rightly Decided?", Steven Arrigg Koh

Faculty Scholarship

“Is this case rightly decided?” From the first week of law school, every law student must grapple with this classroom question. This Essay argues that this vital question is problematically under-specified, creating imprecision in thinking about law. This Essay thus advocates that law professors should present students with a three-part framework: whether a case is rightly decided legally, morally, or sociologically.

Additionally, this Essay argues that disaggregating the question exposes deeper deficiencies in legal education. Many law professors do not provide students with serious grounding to engage in rigorous thinking about the relationship between law, morality, and justice, not to …

Treating Sex And Gender Differences As A Continuous Variable Can Improve Precision Cancer Treatments, Wei Yang, Joshua B Rubin

2020-Current year OA Pubs

BACKGROUND: The significant sex and gender differences that exist in cancer mechanisms, incidence, and survival, have yet to impact clinical practice. One barrier to translation is that cancer phenotypes cannot be segregated into distinct male versus female categories. Instead, within this convenient but contrived dichotomy, male and female cancer phenotypes are highly overlapping and vary between female- and male- skewed extremes. Thus, sex and gender-specific treatments are unrealistic, and our translational goal should be adaptation of treatment to the variable effects of sex and gender on targetable pathways.

METHODS: To overcome this obstacle, we profiled the similarities in 8370 transcriptomes …

Joint Energy And Security Optimization In Underwater Wireless Communication Networks, Kazi Y. Islam, Iftekhar Ahmad, Yue Rong, Daryoush Habibi

Research outputs 2022 to 2026

Underwater wireless communication networks (UWCNs) can support a wide range of applications in the underwater domain, including mining and drilling, coastline monitoring, border surveillance, and submarine/mine detection. Some of these applications are sensitive in nature (e.g., military) and demand stringent security requirements for data communications. In order to prevent malicious attacks (e.g., jamming) in these UWCNs, robust security countermeasures must be implemented. Additionally, sensitive data communications must be protected. However, computationally expensive security protocols, such as encryption, can severely shorten UWCN lifetime, where battery-powered nodes already suffer from scarce energy supplies.

Corrosion And Passivation Behavior Of Laser Powder Bed Fusion Produced Ti-6al-4v Under Various Prior Plastic Deformation Strains, P. Qin, L. Y. Chen, Y. J. Liu, S. X. Liang, H. Sun, L. C. Zhang

Research outputs 2022 to 2026

This work investigated the corrosion behavior of LPBF-produced Ti-6Al-4V under varying compression strains in a 3.5 wt% NaCl solution. It identifies that increasing compression strain causes significant alterations in the acicular a'-Ti phase (coarsening, breakage, and further coarsening). Corrosion resistance decreases with higher strains due to deformed a'-Ti phases, leading to increased film growth kinetics (from 0.09× 10−10 cm2/s increase to 12.75 × 10−10 cm2/s). Samples under higher strains (e.g., 32%) exhibit fluctuations in corrosion behavior due to initiated cracks and subsequent crevice corrosion. These findings are vital for understanding LPBF-produced Ti-6Al-4V in applications requiring mechanical strength and corrosion resilience.
