title: Interim Sediment Management Plan for First Dam, Logan River
Creators: name: Bose, Thirumurugan
Publisher: name: Utah State University
Year: 2004

description: Sediment is a serious problem in the management of dams all over the world. In this project an interim sediment management plan for First Dam, on the Logan River in northern Utah, is discussed. The objective of the plan is to control the sediment budget of the reservoir in such a way that other reservoir maintenance activities (e.g., unusual draw downs for structural repairs) will produce minimal downstream environmental impacts on water quality and aquatic resources.
This report presents a detailed literature review of the various sediment management practices used for reservoir sediment control. It also discusses the downstream effects of sediment flushing and sluicing events. In addition, several sediment management alternatives applicable for the case study reservoir are discussed, including their advantages and disadvantages. An interim recommendation for sediment management at First Dam is proposed, and sampling and monitoring procedures required during and between sediment flushing events are proposed.
The future work of the project of which this report is a part will be to obtain results from sediment flushing experiments that are described here, to analyze the data obtained from these experiments for better assessment of sediment management plans for First Dam, and utilize this information to prepare general sediment management guidelines for small reservoirs in Utah.
title: The Effectiveness of Using an iPad Literacy Application to Engage Early Readers With and Without Hearing Loss
Creators: name: Brown, K. Michelle
Publisher: name: Utah State University
Year: 2015

description: Previous research has found that engagement is key for the success of early readers. There is not sufficient previous research to show how best to engage early readers, particularly with mobile technologies, and almost none on the engagement of those with hearing loss. Electronic and mobile devices have been used in previous research to increase the engagement and success of students. The Reading for All Learners beginning reading curricula iPad application was adapted to include child and adult narrators and multiple modes of access to sound. Recordings of 24 (12 typical and 12 with hearing loss) early readers, ages four to six years, were made with the children and a parent using the beginning reading app with an adult narrator and a child narrator, and reading a print book. Parents completed a post treatment questionnaire with socio-demographic information and opinions on their child’s interest in the different books. The videos were coded for engagement using a rubric the researchers created for this study. This paper describes research findings related to student engagement with the adaptions on the iPad and preferences for child or adult voices.
title: A Petrographic Analysis of the Relationship between Porosity and Organic Matter in the Permian Phosphoria Formation of Northeastern Utah
Creators: name: Tackett, Larry
Publisher: name: Utah State University
Year: 2014

description: The Permian Phosphoria Formation is a reservoir for oil and gas in the western United States, as well as a major source of phosphate. This study examined the relationship between phosphate richness and porosity exhibited in the formation. Petrographic analysis was carried out on rock samples collected from the Phosphoria (Park City) Formation located north of Vernal, Utah, on the southern flank of the Uinta Mountains.
The analysis demonstrated an inverse relationship between organic richness and porosity in the Phosphoria Formation. Porosity is controlled by lithology, amount of cementation, weathering, and amount of fecal pellets, which are the source of phosphate within the unit. Fecal pellets in the Phosphoria Formation contain and concentrate phosphate. Porosity is highest in strata with low levels of organic matter, near the middle of the geological unit, with increased organic matter near the upper and lower contacts, yet the relationship between porosity and organic matter is not necessarily a linear one, as other factors likely control the amount of porosity observed in the unit. Contributing factors include acidic ground waters, diagentic history, and the amount of calcite cement.
A clear understanding of what controls porosity within the Phosphoria Formation has important implications for evaluating the unit as it is an important reservoir unit, as well as assessing phosphate richness for mineral extraction in the Western United States

description: In the popular approach of "Bayesian variable selection" (BVS), one uses prior and posterior distributions to select a subset of candidate variables to enter the model. A completely new direction will be considered here to study BVS with a Gibbs posterior originating in statistical mechanics. The Gibbs posterior is constructed from a risk function of practical interest (such as the classification error) and aims at minimizing a risk function without modeling the data probabilistically. This can improve the performance over the usual Bayesian approach, which depends on a probability model which may be misspecified. Conditions will be provided to achieve good risk performance, even in the presence of high dimensionality, when the number of candidate variables "$K$" can be much larger than the sample size "$n$." In addition, we develop a convenient Markov chain Monte Carlo algorithm to implement BVS with the Gibbs posterior.

title: The Expected Value of an Advantage Blackjack player
Creators: name: Jensen, Kamron
Publisher: name: Utah State University
Year: 2014

description: The following paper takes an in-depth look at the gambling game Blackjack, also known as Twenty-One, and asks the question: If the game is beatable, how much can one expect to win playing Blackjack? This paper starts by explaining how the game is played and continues by telling of how Thorpe (1962) discovered that the game can be beaten. It then goes into detail of how the game has changed over the past 50 years and what it takes to beat the game today. To find the expected value of a winning strategy, I create a computer program to run millions of simulations to output thousands of results. Conclusions are drawn as a result of the simulation analysis. Results show how to win more than $50 each hour of play.
title: Those Who See: Emily Dickinsons and May Swensons Poetic Language of Spiritual and Scientific Possibility
Creators: name: Latham, Samantha
Publisher: name: Utah State University
Year: 2015

description: Emily Dickinson and May Swenson are major American poets who use scientific language in order to explore the productive tension developed when core spiritual beliefs are challenged by new scientific observations and theories. Rather than shrink from the uncertainty resulting from the challenge to faith posed by Darwin in nineteenth-century America, Dickinson and Swenson blend scientific and spiritual language to move beyond the binary opposition often seen as separating these discourses. Dickinson responds most immediately to the advent of Darwinian thought, while Swenson builds on the work of Dickinson as she examines twentieth-century scientific discoveries ranging from the microscopic (the discovery of DNA) to the macroscopic (discoveries due to space exploration). In their consideration of the implications posed by these scientific discoveries, Dickinson and Swenson provide a model of thinking that frames doubt not as a threat to belief but rather as a source of spiritual richness that is grounded in questions rather than answers.

description: The possible variation of the fine structure constant may be due to the non-minimal coupling of the electromagnetic field to a light scalar field which can be the candidate of dark energy. Its dynamical nature renders the fine structure constant varies with time as well as space. In this paper we point out the spatial fluctuation of the fine structure will modify the power spectra of the temperature and the polarization of the cosmic microwave background. We show explicitly that the fluctuations of the coupled scalar field generate new temperature anisotropies at the linear order and induce a $B$ mode to the polarization at higher order in general.

description: We present direct numerical simulations of the equations of compressible magnetohydrodynamics in a wedge-shaped spherical shell, without shear, but with random helical forcing which has negative (positive) helicity in the northern (southern) hemisphere. We find a large-scale magnetic field that is nearly uniform in the azimuthal direction and approximately antisymmetric about the equator. Furthermore, the large-scale field in each hemisphere oscillates on nearly dynamical time scales with reversals of polarity and equatorward migration. Corresponding mean-field models also show similar migratory oscillations with a frequency that is nearly independent of the magnetic Reynolds number. This mechanism may be relevant for understanding equatorward migration seen in the solar dynamo.

title: Managing the Spread of Alfalfa Stem Nematodes Ditylenchus dipsaci: the Relationship Between Crop Rotation and Pest Re-emergence
Creators: name: Jordan, Scott
Publisher: name: Utah State University
Year: 2015

description: Alfalfa is a critical cash/rotation crop in the western region of the United States, where it is common to find crops affected by the alfalfa stem nematode (Ditylenchus dipsaci). Understanding the spread dynamics associated with this pest would allow end-users to design better management programs and farming practices. This is of particular importance given that there are no nematicides available against alfalfa stem nematode and control strategies largely rely on crop rotation to non-host crops or by planting resistant varieties. I present a basic host-parasite model that describes the spread of the alfalfa stem nematode on alfalfa crops. With this discrete time model I am able to portray a relationship between the length of crop rotation periods and the time at which the density of nematode-infested plants becomes larger than that of healthy ones in the post-rotation alfalfa. The numerical results obtained are consistent with farming practice observations, suggesting that the model could play a role in the evaluation of management strategies.

description: Spatial separation of electrons and holes in graphene gives rise to existence of plasmon waves confined to the boundary region. Theory of such guided plasmon modes within hydrodynamics of electron-hole liquid is developed. For plasmon wavelengths smaller than the size of charged domains plasmon dispersion is found to be ω~ q^(1/4). Frequency, velocity and direction of propagation of guided plasmon modes can be easily controlled by external electric field. In the presence of magnetic field spectrum of additional gapless magnetoplasmon excitations is obtained. Our findings indicate that graphene is a promising material for nanoplasmonics.

Introdução: No Brasil, a população em situação de rua (PSR) enfrenta a falta de políticas públicas adequadas às suas necessidades de saúde, especialmente no campo da odontologia. O aumento da PSR e a precariedade dos serviços tornam urgente a criação de ações mais inclusivas e humanizadas. Estudar e propor melhorias no atendimento odontológico é crucial, como no programa Consultório na Rua (CnaR), que facilita o acesso ao SUS e integra essa população ao cuidado contínuo. Objetivos: Avaliar os aspectos do atendimento odontológico à PSR via CnaR, além de apresentar o contexto das políticas públicas do Sistema Nacional de Saúde. Material/Métodos: Foram realizadas buscas bibliográficas com o objetivo de explorar a relação entre a saúde bucal e a população em situação de rua. As pesquisas foram realizadas no SciELO Brasil, Google Acadêmico e posteriormente na plataforma do Ministério do Desenvolvimento Social (MDS). Além disso, Documentos legais, como a Constituição Federal, foram consultados para embasamento normativo. Foram adotados parâmetros específicos para assegurar a pertinência e a atualização das informações, considerando artigos publicados no período de 2009 a 2025. Resultados: Estudos indicam que as políticas públicas para PSR têm sido ineficazes no acesso à saúde. Estratégias como o CnaR oferecem uma solução viável, proporcionando cuidados odontológicos acessíveis. A saúde bucal deve ser parte do cuidado integral, com foco na dignidade e nos direitos humanos. Conclusão: Conclui-se que estudos sobre o CnaR são fundamentais para promover conhecimento e ações focadas na PSR, com políticas públicas éticas e atenção à qualidade de vida dessa população.

description: Nontrivial isometric embeddings for flat metrics (i.e., those which are not just planes in the ambient space) can serve as useful tools in the description of gravity in the embedding gravity approach. Such embeddings can additionally be required to have the same symmetry as the metric. On the other hand, it is possible to require the embedding to be unfolded so that the surface in the ambient space would occupy the subspace of the maximum possible dimension. In the weak gravitational field limit, such a requirement together with a large enough dimension of the ambient space makes embedding gravity equivalent to General Relativity, while at lower dimensions it guarantees the linearizability of the equations of motion. We discuss symmetric embeddings for the metrics of flat Euclidean three-dimensional space and Minkowski space. We propose the method of sequential surface deformations for the construction of unfolded embeddings. We use it to construct such embeddings of flat Euclidean three-dimensional space and Minkowski space, which can be used to analyze the equations of motion of embedding gravity.

description: The University of California (UC) and its notorious 1949 loyalty oath scandal may be the most popular and widely discussed case study of post-WWII political repression within American universities, but it was not the first casualty. That "honor" goes to the University of Washington (UW) in 1946, a year before President Truman enacted Executive Order 9835 requiring federal employees to sign oaths of loyalty to the US Constitution. That year, Washington became one of the first states to create its own internal fact-finding committee on un-American activities. And, among this committee's first targets for rooting out Communists, fellow-travelers, socialists, or any other unsavory subversive types was the University. University president Raymond B. Allen supported and facilitated the witch hunt on his campus in every way possible. In a menacing, albeit possibly intending to be helpful gesture, before the committee arrived on campus, Allen warned Communist faculty members to leave their positions immediately, to quit their careers, before they were smoked out.

title: Efficient Parallel Approaches to Financial Derivatives and Rapid Stochastic Convergence
Creators: name: Harper, Mario
Publisher: name: Utah State University
Year: 2015

description: This Thesis explores the use of different programming paradigms, platforms and languages to maximize the speed of convergence in Financial Derivatives Models. The study focuses on the strengths and drawbacks of various libraries and their associated languages as well as the difficulty of importing code into massively parallel processes. Key languages utilized in this project are C++, Python, Java, C, and Matlab. Along with these languages, several multiprocessing libraries such as C++ AMP, Python NumbaPro, Numpy, Anaconda, Finance Toolkit and such were compared. The results of the development and implementation of code suggests that once we massively parallelize the operations, the only difference in speeds across systems are found only in the unique language's overhead. The findings also suggest that in terms of development and testing time, one should choose to utilize a language they are most familiar with rather than to try a minimalistic approach using a more base level language.

Additionally, research has observed that aquatic exercise may assist in pain relief, swelling reduction, and ease of movement due to the pressure and warmth of water.7  Aquatic environments can also be used to reduce forces placed on the lower extremities by reducing the weight of the subject through buoyancy.3 Buoyancy can unload a participant’s body weight by as much as 70% when submerged to the xiphoid process.

title: An Integrated Approach to Exploit Linkage Disequilibrium for Ultra High Dimensional Genome-wide Data
Creators: name: Carlsen, Michelle
Publisher: name: Utah State University
Year: 2015

description: This paper presents improved methods for analysis of genome-wide association studies in contemporary genetic research. Thanks to current sequencing methods, half to one million single-nucleotide polymorphisms (SNPs) can be feasibly generated within any given population, and there are often correlations among SNPs that cause truly causative loci to be confounded by correlated neighboring loci. Additionally, complex traits are often jointly affected by multiple genetic variants with each having small or moderate individual effects. To address these issues in genome-wide association studies, we propose a novel statistical approach, DCRR, to detect significant associations between large numbers of SNPs and phenotypes. We applied DCRR on simulations of that varied in marker allele frequencies, linkage disequilibrium, and the numbers of SNPs considered; and we analyzed a previously published Arabidopsis thaliana dataset of an AvrRpm1 binary trait. Our distance correlation was effective in ranking SNPs while the logistic ridge regression detected causative SNPs without including spurious correlated neighbors. Our results indicate that DCRR is an effective and reliable method that can improve the accuracy and efficiency of large association datasets.

description: In this paper, we derive explicit product formulas and positive convolution structures for three continuous classes of Heckman-Opdam hypergeometric functions of type $BC$. For specific discrete series of multiplicities these hypergeometric functions occur as the spherical functions of non-compact Grassmann manifolds $G/K$ over one of the (skew) fields $\mathbb F= \mathbb R, \mathbb C, \mathbb H.$ We write the product formula of these spherical functions in an explicit form which allows analytic continuation with respect to the parameters. In each of the three cases, we obtain a series of hypergroup algebras which include the commutative convolution algebras of $K$-biinvariant functions on $G$.
Unsteady pulsating flowfield over spiked axisymmetric forebody at hypersonic flows

description: The paper gives experimental observations on the hypersonic flow past an axisymmetric flat-face cylinder with a protruding sharp-tip spike at a freestream Mach number of $M_\infty = 8.16$ at two different freestream Reynolds numbers based on the base body diameter ($Re_D = 0.76 \times 10^6$, and $3.05 \times 10^6$). Furthermore, modal analysis is done on schlieren images to understand the flow dynamics parallel with the unsteady pressure measurements. The protruding spike of length to base body diameter ratio of $[l/D]=1$ creates a familiar unsteady flowfield called 'pulsation.' Pressure loading and fluctuation intensity at two different $Re_D$ cases are calculated. A maximum drop of 98.24\% is observed in both parameters between the high and low ReD cases. Based on the analysis, a difference in the pulsation characteristics are noticed, which arise from two vortical zones, each from a system of two `$λ$' shocks formed during the `collapse' phase ahead of the base body. The interaction of shedding vortices from the $λ$-shocks' triple-points, along with the rotating stationary waves, contributes to the asymmetric high-pressure loading and the observation of shock pulsation on the flat-face cylinder. The vortical interactions form the second dominant spatial mode with a temporal mode carrying a dimensionless frequency ($f_2D/u_\infty \approx 0.34$) almost twice that of the fundamental frequency ($f_1D/u_\infty \approx 0.17$). The observed frequencies are invariant irrespective of the ReD cases. However, for the high-frequency range, the spectral pressure decay is observed to follow an inverse and -7/3 law for the low and high $Re_D$ cases, respectively.

title: Factors Influencing Solid-Waste Management in the Developing World
Creators: name: McAllister, Jessica
Publisher: name: Utah State University
Year: 2015

description: As the world becomes more urbanized and developed consumption rates are on the rise. An inevitable consequence of more consumption is the rapid increase in the amount of solid waste that is produced. Today, solid-waste management (SWM) conditions in the developing world are often quite dire and reminiscent of those found in the developed world several generations ago. The impact of inadequate SWM practices on natural and human environments is now being acknowledged. This report is founded on a comprehensive literature review concerning SWM in developing countries. It also introduces a preliminary research design relevant to a SWM assessment for a hypothetical situation in Peru. The literature review is organized according to three categories of constraints—each paired with intervention concepts— that contribute to the mismanagement of solid waste. These are: 1) culture, knowledge, and microeconomics; 2) infrastructure, social provisions, and technology; and 3) policy, institutions, and macroeconomics. A fourth topic, namely integrated systems for SWM, is also reviewed because it allows for the simultaneous use of multiple interventions to address multiple constraints. Solid-waste management is a multidimensional issue that incorporates political, institutional, social, environmental, and economic aspects. Improving SWM in developing countries requires efforts to raise public awareness, increase funding, build expertise, and invest in infrastructure. To make progress communities will need to embrace new systems for SWM that are participatory, contextually integrated, complex, and adaptive.

description: The composition of vocal parts and their relation to instrumentation poses several challenges to the composer. Linked to the issue is the question of how to deal with language. In this submission, I explore diverse vocal techniques ranging from traditional singing in manifold tonal or atonal contexts to the use of the human voice in modes such as speaking, screaming, shouting, whispering or whistling. This research develops ways to extend these techniques and to find an individual approach to singing in stage works. I tread this path in a portfolio of ten works exploring the use of the voice in various instrumentations. Eight of these compositions are structured around an assortment of historically popular line-ups such as Kunstlied, Orchesterlied, Ensemblelied, a capella choir work or chamber opera. Later, I expanded the compilation and incorporated works with a less traditional setup such as a piano concerto, amalgamating genres by including singers in the ensemble, and a piece for solo voice and electronics. The influence of the orchestration on the use of the voice is also considered within the new works. In each of the ten pieces, I approach the voice from a different angle and focus on a specific compositional parameter. This parametric approach allows me to change perspective and to adapt the applied vocal techniques according to the instrumentation and the characteristics of the underlying text. I aim to combine semantic immediacy and comprehensibility with the drawing of clear characters and atmospheres.

This new framework needs to address both the imminent threat that increased tourism brings (overuse, crowding and additional wear) to the site as well as the widening range of experiences that tourists expect. Over the last decades, management frameworks have been developed in many fields of tourism to address similar issues. The most widely known of these approaches are the Recreational Opportunity Spectrum (ROS), the Tourism Opportunity Spectrum (TOS) and the Ecotourism Opportunity Spectrum (ECOS). These frameworks provide several classes of opportunities in which tourist may engage and enlist the management guidelines necessary to preserve the integrity of each class. This paper develops a tourism approach to archaeology adapted from these examples.
The new framework herein proposed is named the Archaeological Tourism Opportunity Spectrum (ATOS). This spectrum proposes four separate tourism classes within which different archaeological tourism experiences are offered. Development and management guidelines for each tourism class are created by looking at the outcome of four tourism classes as they are defined by seven archaeological site-based factors. These guidelines will create clear management objectives for each of the four classes. It will also facilitate an opportunity for small regional archaeological sites to be managed as a network providing an increased range of experiences for all tourists.
The application of ATOS is tested by applying the recommendations of this newly proposed framework to five established sites at Hovenweep National Monument. It is predicted that the ATOS will illuminate the opportunity for changes within the existing design, allowing for a wider range of experience opportunities.

description: COVID-19, for which no confirmed therapeutic agents are available, has claimed over 48,14,000 lives globally. A feasible and quicker method to resolve this problem may be ‘drug repositioning’. We investigated selected FDA and WHO-EML approved drugs based on their previously promising potential as antivirals, antibacterials or antifungals. These drugs were docked onto the nsp12 protein, which reigns the RNA-dependent RNA polymerase activity of SARS-CoV-2, a key therapeutic target for coronaviruses. Docked complexes were reevaluated using MM-GBSA analysis and the top three inhibitor-protein complexes were subjected to 100 ns long molecular dynamics simulation followed by another round of MM-GBSA analysis. The RMSF plots, binding energies and the mode of physicochemical interaction of the active site of the protein with the drugs were evaluated. Suramin, Penciclovir, and Anidulafungin were found to bind to nsp12 with similar binding energies as that of Remdesivir, which has been used as a therapy for COVID-19. In addition, recent experimental evidences indicate that these drugs exhibit antiviral efficacy against SARS-CoV-2. Such evidence, along with the significant and varied physical interactions of these drugs with the key viral enzyme outlined in this investigation, indicates that they might have a prospective therapeutic potential in the treatment of COVID-19 as monotherapy or combination therapy with Remdesivir.

Exploring the Use of Instrumented Insoles to Estimate Trunk Local Dynamic Stability During Treadmill Walking

description: Gait assessments can help identify individuals at an elevated risk of falling. Gait variability and local dynamic stability (LDS) are considered the most valid measures to assess gait stability and predict gait-related falls. Specifically, LDS of the trunk is most often used to assess gait stability given its important contribution to the centre of mass and the ability to discriminate between fallers and non-fallers using its kinematics. Reliable wearable sensors can be implemented in real-world gait assessments to actively screen for fall risk. Instrumented insoles are an example of unobtrusive wearable technology that can perform accurate gait assessments in real-world settings; however, they have not been validated for gait stability assessments, and cannot directly measure trunk LDS. The purpose of this thesis was to develop a framework to estimate gait stability using instrumented insoles. Fifteen participants were recruited to walk on a treadmill for seven minutes at their preferred walking speed while wearing instrumented insoles and a full-body inertial measurement unit suit. The reliability of foot LDS calculated from instrumented insole data was evaluated against the inertial measurement unit suit using intraclass correlation coefficients. Trunk LDS, measured via the IMU suit, was then predicted by applying linear regressions to the insole-derived metrics. A simple linear regression was used to establish the base amount of variance in trunk LDS that could be explained by foot LDS. Subsequently, a multiple linear regression model consisting of the standard deviation of stride time, standard deviation of double support time, mean single support time, mean yaw variability, and median absolute deviation of yaw variability was used to estimate trunk LDS. Results show that instrumented insoles can reliably measure foot LDS (ICC₃,₁ = 0.860). Moreover, the multiple linear regression explained 47.7% more variance than the simple linear regression (adjusted R² of 0.845 versus 0.368). This thesis demonstrates that instrumented insoles are an appropriate measurement tool for foot stability and that they can be used to predict trunk LDS with good accuracy during gait.

description: The Belle II experiment will measure the rare decays $B\to Kνν$ and $B\to K^* νν$ with increased sensitivity which can hence be expected to serve as a very efficient probe of new physics. We calculate the relevant branching ratios in low-energy effective field theory (LEFT) including an arbitrary number of massive sterile neutrinos and discuss the expected sensitivity to the different operators. We also take into account the longitudinal polarisation fraction $F_L$ and the inclusive decay rate $B\to X_sνν$. In our investigation we consider new physics dominantly contributing to one and two operators both for massless and massive (sterile) neutrinos. Our results show a powerful interplay of the exclusive decay rates $B\to Kνν$ and $B\to K^*νν$, and a surprisingly large sensitivity of the inclusive decay mode to vector operators even under conservative assumptions about its uncertainty. Furthermore, the sensitivity of $F_L$ is competitive with the branching ratio of $B\to K^* νν$ in the search for new physics contributing to scalar operators and thus also complementary to $B\to Kνν$ and $B\to X_sνν$.

title: Comparison of Propulsive Power During Loaded Countermovement Jumps Performed in Water versus Land in College Aged Males

description: As use of an aquatic environment increases as a training and rehabilitative tool, the purpose of this study was to assess peak propulsive power in loaded countermovement jumps (CMJ) in water and compare them to loaded CMJ on land. 20 college aged (24.6±3.6 years) recreationally active males performed 4 randomized countermovement jumps on a force plate with increasing loads (bodyweight [BW], BW+10%, BW+20%, BW+30%) in two environments: immersed in water at the xiphoid process and on land. Peak power (PP) and mean power (MP) normalized to apparent mass were assessed for all jumps. A 2 (environment) by 4 (load) repeated measures ANOVA was used to determine main effects and the interaction. PP was greater in the water for all loading conditions compared to land (13.1±3.4, 12.3±3.6, 10.4±3.4, 9.9±3.1 kW vs 5.8±1.4, 5.7±1.4, 5.8±1.4, 5.9±1.4 kW) for the BW, BW+10%, BW+20% and BW+30% conditions, respectively. The same trend and magnitude differences were identified for MP (5.5±1.7, 5.2±2, 4.4±1.5, 4.1±1.6 kW vs 2.6±0.8, 2.4±0.8, 2.5±0.8, 2.5±0.7 kW) for water vs land, respectively. The trend for decrease in PP and MP in water was significant while there were no significant trends for decreases in PP and MP on land. These results suggest loading BW on land in the range of 10-30% essentially has no detrimental impact on PP and MP measures yet creates a significant reduction when performed in water. Potential decreases in force production and/or movement velocities during takeoff may account for these observed differences due to environment. Further research could identify these differences and provide valuable insights for strength and conditioning professionals to use an aquatic environment to complement traditional land-based training.

description: A new model of physics, with a hidden conformal sector which manifests itself as an unparticle coupling to Standard Model particles effectively through higher dimensional operators, predicts strong collider signals due to unparticle self-interactions. We perform a complete analysis of the most spectacular of these signals at the hadron collider, pp -> 4photon and pp ->2photon,2gluon. These processes can go through the three-point unparticle self interactions as well as through some s and t channel diagrams with one and/or two unparticle exchanges. We study the contributions of individual diagrams classified with respect to the number of unparticle exchanges and discuss their effect on the cross sections at the Tevatron and the LHC. We also restrict the Tevatron bound on the unknown coefficient of the three-point unparticle correlator. With the availability of data from Tevatron, and the advent of the data emerging from the LHC, these interactions can provide a clear and strong indication of unparticle physics and distinguish this model from other beyond the standard model scenarios.
