Approach: The design utilizes a unique interferometer and a custom spectrometer that captures four highly aligned spectra with a single area/multi-line camera. Each pair of spectral lines is highly aligned, and their subtraction yields balanced detected spectra of the …

Effects On Force, Velocity, Power, And Muscle Activation Of Resistances With Variable Inertia Generated By Programmable Electromechanical Motors During Explosive Chest Press Exercises, Luca Zoffoli, Silvano Zanuso, Andrea Biscarini

Research outputs 2022 to 2026

Strength training machines incorporating advanced electro-mechanical technologies can produce hybrid resistances with variable inertia, such as a resistance that progressively changes from gravitational (inertial) to pneumatic (non-inertial) across the range of motion (ROM). To explore the biomechanical effects of these innovative resistances, a robotic chest press machine was programmed to offer three distinct inertial profiles: gravitational-type constant inertia throughout the ROM (IFULL); no inertia (IZERO); and linearly descending inertia across the ROM (IVAR). Ten healthy adults performed five maximal-effort, explosive chest press movements under each inertial profile at 30, 50 and 70% of their one-repetition maximum. During each trial, muscle …

METHOD: An online survey was conducted among U.S. adults aged 65-90 (N = 581; M_age=71.4, SD ± 4.81; 51% female). Measures included the 12-item Expectations Regarding Aging scale, the 8-item PROMIS Cognitive Abilities scale (current subjective cognition), and the 12-item Everyday Cognition scale (SCD). We used generalized linear models …

Examining Children's Verb Learning In The United States And Japan: Do Comparisons Help?, Jane B. Childers, Mutsumi Imai, Masato Ohba, Faith Perry, Leah Marsh

Psychology Faculty Research

Learning verbs is an important part of learning one's native language. Prior studies have shown that children younger than 5 years can have difficulty in learning and extending new verbs. The current study extended these studies by showing children multiple events that can be compared during learning, including Japanese- and English-speaking children. In the study, 2-, 3-, and 4-year-olds saw two similar events and then one varied (progressive alignment) or three varied (low alignable) events in a learning phase before test, and this was repeated for four sets. Children were asked to extend these novel verbs in easy (non-cross-mapping) and …

A Mathematical Model Of The Electrical Power Management Systems Using The Core Values In Cooperative Game, Mohammed Musa, Jabbar Abbas

Journal of Applied Sciences and Nanotechnology

In the context of game theory, cooperative game has been applied in several fields and can be successfully used to evaluate the players (people or companies) involved. In cooperative game theory, the core is a concept that represents the set of feasible allocations (or distributions of total payoff) among players that cannot be improved upon by any coalition of players. This paper aims to apply a mathematical model to modeling cooperation among power stations and fuel supply producers using a core value-based optimization algorithm. We use the cooperative game to show the potential cost in cooperation through an optimization algorithm …

The Importance Of Public Health In College Populations: Why Vaccines Are Important, Kashish Poore

Honors Program: Senior Projects (Public)

This paper examines the importance of vaccines in college populations, where high-density living environments create unique vulnerabilities to infectious disease outbreaks. Despite vaccine mandates at most institutions, research indicates that many college students possess incomplete understanding of vaccine mechanisms and importance. The paper addresses three interconnected aspects: the biological foundations of vaccine-induced immunity, the significance of vaccination in collegiate settings, and the current state of vaccine literacy among students. Historical outbreaks on campuses, including meningitis at Princeton and mumps across several institutions, highlight the consequences of undervaccination. Social media misinformation has contributed significantly to vaccine hesitancy, particularly since COVID-19. The …

Explaining Police Officer Intentions To Leave Their Career Field, Michael T. Rossler, Charles Scheer

Faculty Publications - Criminal Justice Sciences

Research examining police officer retention has generally relied upon general work environment predictors to explain intentions to leave a police career. Recent research has applied theory explaining departures as a multistep process, where job satisfaction and stress mediate the relationship between work conditions and leaving the profession. These prior inquiries have been methodologically limited in the number of predictors and agencies included. The current inquiry uses a survey of eight police agencies to test the conceptual framework that job satisfaction and stress mediate the relationship between workplace environment and intentions to leave policing. Findings indicate that many commonly theorized predictors …

Hoylman, Amy R. Hudson, John W. Nielsen-Gammon, Natalie A. Umphlett, Elliot Wickham, Aparna Bamzai-Dodson, Royce Fontenot, Brian Fuchs, John Hammond, Jeffrey E. Herrick, Mike Hobbins, Andrew Hoell, Jacob Jones, Erin Lane, Zachary Leasor, Yongqiang Liu, Jason A. Otkin, Dennis Todey, Roger Pulwarty

Geography

Drought is a period of abnormally dry weather that leads to hydrological imbalance. Drought assessments determine the characteristics, severity, and impacts of a drought. Climate change adds conceptual and quantitative challenges to traditional drought assessments. This paper highlights the challenges of assessing drought in a climate made non-stationary by human activities or natural variability. To address these challenges, we then identify 10 key research priorities for advancing drought science and improving assessments in a changing climate. The priorities focus on improving drought indicators to account for non-stationarity, evaluating drought impacts and their trends, addressing regional differences in non-stationarity, determining the …

Forest Carbon Modeling Improved Through Hierarchical Assimilation Of Pool-Based Measurements, Yu Zhou, Christopher A. Williams

Geography

Accurate assessment of forest carbon dynamics is a critical element of appraising forest-based Natural Climate Solutions. National forest inventory and analysis (FIA) data provide valuable pool-based estimates of carbon stocks, but have been underutilized to inform carbon cycle modeling for forest carbon dynamics with stand development. This study introduces a hierarchical data assimilation (HDA) framework to optimize modeling parameters by incrementally assimilating measured carbon pool data into the model. We found that most carbon stocks could be reproduced by constrained parameters after each HDA step. Using aboveground live biomass (AGB) alone in HDA was able to reproduce the AGB trajectories …

A Wave-Optics Bsdf For Correlated Scatterers, Ruomai Yang

Dartmouth College Master’s Theses

In this project, we present a wave optics bidirectional scattering distribution function(BSDF) for the material with a collection of scatterers, such as certain fabrics with pores or foggy glass, where the corona effect can be observed under strong light sources. This effect arises from the diffraction of individual scatterers and the interference between them. To describe this effect, we treat each scatterer as an aperture to calculate diffraction, while using a pair correlation function to represent their spatial relationships and calculate the interference. This two-level decomposition allows us to derive a BSDF that can control both the individual diffraction function …

Short-Run Subsidies And Long-Run Willingness To Pay: Learning And Anchoring In An Agricultural Experiment In Ethiopia, Solomon Balew, Erwin Bulte, Menale Kassie

All Peer-Reviewed Publications

We study how temporary provision of an agricultural innovation at zero cost affects long-run demand for that innovation. Our experimental design enables us to distinguish between an “anchoring effect” of subsidies and a “learning effect.” We document large and persistent anchoring and learning effects. For the innovation that we consider, an integrated pest management (IPM) package for Ethiopian smallholder farmers, the learning effect dominates the anchoring effect, so temporary subsidized provision promotes long-run technology diffusion.

Synchronous Presentation Of Right Parotid Branchial Cleft Cyst And Left Neck Hpv-Associated Cystic Metastatic Squamous Cell Carcinoma: A Diagnostic Quandary, Syed H A Naqvi, Syed H S Naqvi, David Allen, Arturo A Eguia, Jing Liu, Ron J Karni

Faculty, Staff and Student Publications

Branchial cleft cyst arising within the parotid space is considered an extremely rare phenomenon. In contrast, cystic squamous cell carcinoma in the lateral neck is not an uncommon presentation of HPV-related head and neck cancer. Although they have singly been narrated in literature, simultaneous expression of these anomalies has yet to be reported. We describe a case of synchronous presentation of branchial cleft cyst of the right parotid gland and cystic metastatic squamous cell carcinoma of the left neck. These findings are discussed in light of the challenges in fine needle aspiration biopsy of cystic masses, and the risk of …

The Convergence Of World Prosperity And Afterlife Salvation: Neoliberalism And Political Islam In Turkey, Muhammad Andi Firmansyah

Jurnal Politik

This article investigates why Turkey’s middle-to-low-income earners, the segment of the population that has suffered the most from the neoliberal policies of the Adalet ve Kalkınma Partisi (Justice and Development Party AKP), have continued to support the party for so long. Using a case study approach based on secondary data, this article argues that the source of the AKP’s enduring legitimacy lies in their skill in utilising political Islam to consolidate neoliberalism. They strategically framed neoliberal restructuring in an Islamic spirit, generating not only loyal cross-class support but also obedience to neoliberal political projects with all their destructive consequences. The …

Why You Cannot Find A Swing Justice When You Really Need One, Neal Devins

William & Mary Law Review

From Richard Nixon’s 1972 appointment of swing Justice Lewis Powell until Donald Trump’s 2018 appointment of Brett Kavanaugh (to replace swing Justice Anthony Kennedy), the swing Justice ruled the roost. Sometimes voting with the Court’s conservatives and other times with its liberals, the swing Justice often cast the deciding vote and often embraced a sui generis middle ground. Those days now seem like a distant memory. An ideologically simpatico majority coalition drives the post-2018 Roberts Court (especially after Justice Amy Coney Barrett filled Justice Ruth Bader Ginsburg’s seat in 2020). In this Article, I will use the Court’s affirmative action …
