description: Point clouds are widely used in various applications such as 3D modeling, geospatial analysis, robotics, and more. One of the key advantages of 3D point cloud data is that, unlike other data formats like texture, it is independent of viewing angle, surface type, and parameterization. Since each point in the point cloud is independent of the other, it makes it the most suitable source of data for tasks like object recognition, scene segmentation, and reconstruction. Point clouds are complex and verbose due to the numerous attributes they contain, many of which may not be always necessary for rendering, making retrieving and parsing a heavy task.
As Sensors are becoming more precise and popular, effectively streaming, processing, and rendering the data is also becoming more challenging. In a hierarchical continuous LOD system, the previously fetched and rendered data for a region may become unavailable when revisiting it. To address this, we use a non-persistence cache using hash-map which stores the parsed point attributes, which still has some limitations, such as the dataset needing to be refetched and reprocessed if the tab or browser is closed and reopened which can be addressed by persistence caching. On the web, popularly persistence caching involves storing data in server memory, or an intermediate caching server like Redis. This is not suitable for point cloud data where we have to store parsed and processed large point data making point cloud visualization rely only on non-persistence caching.
The thesis aims to contribute toward better performance and suitability of point cloud rendering on the web reducing the number of read requests to the remote file to access data.We achieve this with the application of client-side-based LRU Cache and Private File Open Space as a combination of both persistence and non-persistence caching of data. We use a cloud-optimized data format, which is better suited for web and streaming hierarchical data structures. Our focus is to improve rendering performance using WebGPU by reducing access time and minimizing the amount of data loaded in GPU.
Preliminary results indicate that our approach significantly improves rendering performance and reduce network request when compared to traditional caching methods using WebGPU.

description: Excessive fluoride (F) can lead to abnormal bone biology. Numerous studies have focused on the anabolic action of F yet little is known regarding any action on osteoclastogenesis. Little is known regarding the influence of an individual’s genetic background on the responses of bone cells to F. Four-week old C57BL/6J (B6) and C3H/HeJ (C3H) female mice were treated with NaF in the drinking water (0ppm, 50ppm and 100ppm F ion) for 3 weeks. Bone marrow cells were harvested for osteoclastogenesis and hematopoietic colony-forming cell assays. Sera were analyzed for biochemical and bone markers. Femurs, tibiae and lumbar vertebrae were subjected to microCT analysis. Tibiae and femurs were subjected to histology and biomechanical testing, respectively. The results demonstrated new actions of F on osteoclastogenesis and hematopoietic cell differentiation. Strain specific responses were observed. The anabolic action of F was favored in B6 mice exhibiting dose dependent increases in serum ALP activity (p < 0.001); in proximal tibia trabecular and vertebral BMD (tibia at 50&100ppm, p = 0.001; vertebrae at 50&100ppm, p = 0.023&0.019, respectively); and decrease in intact PTH and sRANKL (p = 0.045 and p < 0.001, respectively). F treatment in B6 mice also resulted in increased numbers of CFU-GEMM colonies (p = 0.025). Strain specific accumulations in bone [F] were observed. For C3H mice, dose dependent increases were observed in osteoclast potential (p < 0.001), in situ trabecular osteoclast number (p = 0.007), hematopoietic colony forming units (CFU-GEMM: p < 0.001, CFU-GM: p = 0.006, CFU-M: p < 0.001), and serum markers for osteoclastogenesis (intact PTH: p = 0.004, RANKL: p = 0.022, TRAP5b: p < 0.001). A concordant decrease in serum OPG (p = 0.005) was also observed. Fluoride treatment had no significant effects on bone morphology, BMD and serum PYD crosslinks in C3H suggesting a lack of significant bone resorption. Mechanical properties were also unaltered in C3H. In conclusion, short term F treatment at physiological levels has strain specific effects in mice. The expected anabolic effects were observed in B6 and novel actions hallmarked by enhanced osteoclastogenesis shifts in hematopoietic cell differentiation in the C3H strain.

description: We consider the problem of estimating a spatially varying density function, motivated by problems that arise in large-scale radiological survey and anomaly detection. In this context, the density functions to be estimated are the background gamma-ray energy spectra at sites spread across a large geographical area, such as nuclear production and waste-storage sites, military bases, medical facilities, university campuses, or the downtown of a city. Several challenges combine to make this a difficult problem. First, the spectral density at any given spatial location may have both smooth and non-smooth features. Second, the spatial correlation in these density functions is neither stationary nor locally isotropic. Finally, at some spatial locations, there is very little data. We present a method called multiscale spatial density smoothing that successfully addresses these challenges. The method is based on recursive dyadic partition of the sample space, and therefore shares much in common with other multiscale methods, such as wavelets and Pólya-tree priors. We describe an efficient algorithm for finding a maximum a posteriori (MAP) estimate that leverages recent advances in convex optimization for non-smooth functions. We apply multiscale spatial density smoothing to real data collected on the background gamma-ray spectra at locations across a large university campus. The method exhibits state-of-the-art performance for spatial smoothing in density estimation, and it leads to substantial improvements in power when used in conjunction with existing methods for detecting the kinds of radiological anomalies that may have important consequences for public health and safety.

description: In this study the changes in properties of the maturing mantle and circumpulpal dentin were quantitatively analyzed. Sections from six fetal bovine undecalcified incisors were used. Regions of mantle and circumpulpal dentin of sequential maturation stages were identified on spectroscopic images acquired by Fourier Transform Infrared Imaging. Spectroscopic parameters corresponding to mineral properties at these stages were analyzed and reported as a function of distance from the cervix of the incisor, the latter representing tissue age. Mineral parameters were correlated with distance from the cervix. Values of these parameters in mantle and circumpulpal dentin were compared. A multi-phasic pattern of changes was found for all the parameters examined, with most of the alterations occurring in the initial maturation period. The patterns of temporal variation in mantle and circumpulpal dentin mineral properties show distinct developmental stages and were not identical for the two dentin compartments. The study showed that mineral maturation in dentin is not a linear process and that mantle dentin is developmentally distinct from circumpulpal dentin, presenting at certain stages different physicochemical events during the maturation of the tissue.

title: An Exploratory and Descriptive Analysis of the Utah Microcredentials Participant Population
Creators: name: Kennett, Daron
Publisher: name: Utah State University

description: This study examined the population of users of the Utah Microcredentials system, a professional learning resource available to all Utah teaching license holders. A microcredential verifies that an educator has successfully demonstrated competency with a specific skill, concept, or instructional tool, and is awarded upon submission of evidence meeting a predetermined set of rubric criteria. During the first stage of the study, quantitative methods such as regression analysis were used to determine the participation rates of educators based on a number of demographic variables, including age, number of years of service as an educator, the rurality of the educator's assigned school, and the Title I status of the educator's assigned school. Stage two used qualitative methods to analyze the characteristics of microcredentials with the highest rates of participation. The results of this study can be used at a number of levels to increase the effectiveness of public education in supporting student outcomes. At the local level, the findings can be used to guide the ongoing development of the Utah Microcredentials platform, ecosystem (microcredential catalog), and user support systems. At the national and international levels, these findings can be used to guide the development of digital credentialing systems in a wide range of fields beyond public education. These findings also point to new routes of investigation for further research.

description: A variation in bone response to fluoride (F−) exposure has been attributed to genetic factors. Increasing fluoride doses (0ppm, 25ppm, 50ppm, 100ppm) for three inbred mouse strains with different susceptibilities to developing dental enamel fluorosis (A/J, a “susceptible” strain; SWR/J, an “intermediate” strain; 129P3/J, a “resistant” strain) had different effects on their cortical and trabecular bone mechanical properties. In this paper, the structural and material properties of the bone were evaluated to explain the previously observed changes in mechanical properties.

title: Characterization of the Long-Distance Dispersal Kernel of White-Tailed Deer and Evaluating Its Impact on Chronic Wasting Disease Spread in Wisconsin
Creators: name: Gouda, Mennatallah
Publisher: name: Utah State University
Year: 2023

description: Chronic Wasting Disease (CWD) is a fatal, untreatable neurodegenerative disease that infects deer and related species. It is highly contagious and caused by abnormal malfunction and assembly of normal cellular proteins into aggregation-prone proteins. The Centers for Disease Control and prevention report that the prevalence of CWD in free-ranging deer in the US is still relatively low. However, in several states the infection rates exceed 1 deer in 10. Deer may uptake CWD from direct interaction with infected individuals or from the environment. Infected individuals shed CWD into the environment through feces, urine, saliva or carcasses, and long-distance dispersal of infected deer poses a danger of spreading CWD to new regions. We propose a mathematical model to capture CWD dynamics and the consequences of long-distance dispersal behavior of White-Tailed Deer (WTD), since there are no dispersal models available to describe the long-distance dispersal behavior of WTD juveniles. Our aim is to characterize long-distance dispersal of WTD juveniles and assess how it may affect CWD spread. We introduce a long-distance dispersal model, based on models of seed transport which accommodate a variety of hypothetical WTD dispersal behaviors. Four dispersal models were obtained by finding the approximate solutions of the seed transport models tweaked to mimic deer dispersal and settling behavior. We used GPS collar data collected in Wisconsin, US to test the accuracy of the models we developed. By calculating the prediction errors made by the models, we adjusted the model parameters, and assessed the competency of models relative to each other. Sensitivity of results was estimated by changing the data randomly to account for the effect of changing data on the results. The settling rate function that resulted in the most supported long-distance dispersal kernel reflects deer preference to not settle down soon after they start dispersal. Then, the impact of long-distance dispersal on CWD spread was quantified using the mathematical model for CWD dynamics we proposed earlier. Our results show that long-distance dispersal can magnify the CWD spread by a factor of 4. Therefore, controlling the total population density and fraction of long-distance dispersers will assist CWD management facilities in managing disease spread.

Creators: name: Durrant, Shelbie
Publisher: name: Utah State University
Year: 2023

description: The cultural pressures of gender conformity and "norms" have lasted as long as the social constructs of gender themselves. Gender is present and can be analyzed in symbols within material culture such as the Russell family funerary monuments located in their private chapel in Chenies, London. Gender, although not always transparently at the front of consciousness, was interacted with, performed, and memorialized in life and death, especially for families that were high status. The presence of gender in these funerary monuments illuminates how expected conformity of gender norms were in this time — so present that they were literally set in stone.

title: Diversity in Tech: Analyzing the Mismatch Between Corporate Framing and Impact
Creators: name: Abulbasal, Rana
Publisher: name: Utah State University
Year: 2023

description: This doctoral dissertation investigates the discrepancy between tech companies' substantial investments in diversity programs and the persistently low representation of Black, Indigenous, and people of color (BIPOC) employees. Despite extensive efforts, discrimination and harassment against women and people of color persist in the industry. The study employs a critical interdisciplinary approach, comprising sociological perspectives on diversity management and two empirical studies. The first scrutinizes tech companies' framing strategies of diversity initiatives on their websites, while the second explores the impact of Diversity, Equity, and Inclusion (DEI) policies on women of color in the industry. By identifying shortcomings and proposing recommendations, this research aims to enhance the effectiveness of corporate diversity efforts in the tech sector.

description: Accuracy of production estimates and the risk of geological hazards are two main concerns that currently impede the development of gas hydrate reservoirs. The understanding of fluid flow in hydrate-bearing sediments is crucial to the accurate estimation of production and is critically influenced by lithology and hydrate saturation. The thesis covers these factors by studying the production behavior of different classes of reservoirs and different permeability-reduction models. The stress-strain constitutive equation of hydrate-bearing sediments plays a vital role in risk assessment. Therefore, a constitutive model was developed from first principles which was successful in capturing the characteristic strain-softening behavior.

description: Both mechanical loading and nitric oxide (NO) have positive influences on bone mass. NO production is induced by mechanical strain via upregulation of eNOS mRNA and protein, the predominant NOS in adult bone. At the same time, strain causes decreased expression of RANKL, a factor critical for osteoclastogenesis. In this study, we harvested primary stromal cells from wild-type (WT) and eNOS(−/−) mice to test whether induction of NO by mechanical strain was necessary for transducing mechanical inhibition of RANKL. We found that strain inhibition of RANKL expression was prevented by NOS inhibitors (L-NAME and L-NMMA) in WT stromal cells. Surprisingly, stromal cells from eNOS(−/−) mice showed significant mechanical repression of RANKL expression (p<0.05). Mechanical strain still increased NO production in the absence of eNOS, and was abolished by SMTC, a specific nNOS inhibitor. nNOS mRNA and protein expression were increased by strain in eNOS(−/−) but not in WT cells, revealing that nNOS was mechanically sensitive. When NO synthesis was blocked with either SMTC or siRNA targeting nNOS in eNOS(−/−) cells however, strain still was able to suppress RANKL expression by 34%. This indicated that strain suppression of RANKL can also occur through non-NO dependent pathways. While our results confirm the importance of NO in the mechanical control of skeletal remodeling, they also suggest alternative signaling pathways by which mechanical force can produce anti-catabolic effects on the skeleton.
title: Long-Distance Recreational Travel Behavior and Implications of Autonomous Vehicles
Creators: name: Acharya, Sailesh
Publisher: name: Utah State University
Year: 2023

description: Have you ever wondered how people travel long distances and how it could be affected by the emergence of autonomous vehicles (AVs)? This dissertation aims to answer those questions by studying the current behavior of long-distance recreational travelers and their preference in the age of AVs. This dissertation has four main goals. First, it seeks to develop a reliable way to measure people’s satisfaction with long-distance recreational trips and understand the similarities and differences between long- and short-distance travel satisfaction. Second, it looks at the connection between how people travel, how satisfied they are with their travel experiences, and how this relates to their overall satisfaction with their destination. Third, it explores how people feel about using AVs for long-distance travel and tries to understand what influences their decisions. Lastly, it looks at the impact of vehicle automation, the interior of AVs, and how people use their time during travel on their choices and preferences. The necessary data is gathered through a survey of 696 people who visited national parks in the US.
The survey responses are analyzed to understand the research objectives, and some interesting insights are obtained. First, a survey instrument (i.e., a list of questions) is developed to accurately measure long-distance travelers’ satisfaction. The analysis discovers that the factors that affect satisfaction with long-distance travel differ from those that affect short-distance travel. Second, a strong link is established between people’s satisfaction with their travel experiences (on the way) and their overall tourism experience (at destination). Third, the study suggests people might travel more frequently and for longer distances with the introduction of AVs. This result means that we should not only focus on managing tourism destinations but also consider the impact on traffic and infrastructure leading to these destinations. Finally, the study finds that people are interested in using their travel time more productively in AVs, but we should be mindful of the negative consequences, such as increased energy consumption and space requirements. In conclusion, this dissertation sheds light on long-distance travel behavior and the potential changes that could come with using AVs. It emphasizes the importance of enjoying the journey, the impact on tourism, and the need for sustainable transportation. So, next time you plan a road trip, remember there’s more to consider than just getting to your destination!

description: Mice lacking HIP/RPL29, a component of the ribosomal machinery, display increased bone fragility. To understand the effect of sub-efficient protein synthetic rates on mineralized tissue quality, we performed dynamic and static histomorphometry and examined the mineral properties of both bones and teeth in HIP/RPL29 knock-out mice using Fourier transform infrared imaging (FTIRI). While loss of HIP/RPL29 consistently reduced total bone size, decreased mineral apposition rates were not significant, indicating that short stature is not primarily due to impaired osteoblast function. Interestingly, our microspectroscopic studies showed that a significant decrease in collagen crosslinking during maturation of HIP/RPL29-null bone precedes an overall enhancement in the relative extent of mineralization of both trabecular and cortical adult bones. This report provides strong genetic evidence that ribosomal insufficiency induces subtle organic matrix deficiencies which elevates calcification. Consistent with the HIP/RPL29-null bone phenotype, HIP/RPL29-deficient teeth also showed reduced geometric properties accompanied with relative increased mineral densities of both dentin and enamel. Increased mineralization associated with enhanced tissue fragility related to imperfection in organic phase microstructure evokes defects seen in matrix protein-related bone and tooth diseases. Thus, HIP/RPL29 mice constitute a new genetic model for studying the contribution of global protein synthesis in the establishment of organic and inorganic phases in mineral tissues.

Fundamental properties of solar-like oscillating stars from frequencies of minimum $Δν$ : II. Model computations for different chemical compositions and mass

description: The large separations between the oscillation frequencies of solar-like stars are measures of stellar mean density. The separations have been thought to be mostly constant in the observed range of frequencies. However, detailed investigation shows that they are not constant, and their variations are not random but have very strong diagnostic potential for our understanding of stellar structure and evolution. In this regard, frequencies of the minimum large separation are very useful tools. From these frequencies, in addition to the large separation and frequency of maximum amplitude, Yıldız et al. recently have developed new methods to find almost all the fundamental stellar properties. In the present study, we aim to find metallicity and helium abundances from the frequencies, and generalize the relations given by Yıldız et al. for a wider stellar mass range and arbitrary metallicity ($Z$) and helium abundance ($Y$). We show that the effect of metallicity is { significant} for most of the fundamental parameters. For stellar mass, for example, the expression must be multiplied by $(Z/Z_{\sun})^{0.12}$. For arbitrary helium abundance, $ M \propto (Y/Y_{\sun})^{0.25} $. Methods for determination of $Z$ and $Y$ from pure asteroseismic quantities are based on amplitudes (differences between maximum and minimum values of \Dnu) in the oscillatory component in the spacing of oscillation frequencies. Additionally, we demonstrate that the difference between the first maximum and the second minimum is very sensitive to $Z$. It also depends on $ν_{\rm min1}/ν_{\rm max}$ and small separation between the frequencies. Such a dependence leads us to develop a method to find $Z$ (and $Y$) from oscillation frequencies. The maximum difference between the estimated and model $Z$ values is about 14 per cent. It is 10 per cent for $Y$.

description: This article examines Pope Francis’ continuation of the tradition of papal apostolic journeys, focusing on his recent visit to Southeast Asia and the Pacific, the longest trip of his papacy. Papal travel has evolved significantly over time, with early popes rarely venturing beyond Rome, except under political or pastoral necessity. However, since Pope Paul VI's groundbreaking travels in the mid-20th century, papal journeys have become a key tool of global diplomacy and religious outreach. This article explores the historical context of papal travel and highlights Pope Francis’ efforts to engage with contemporary global challenges such as interfaith dialogue, religious tolerance, and environmental stewardship. Francis’ recent trip redefines the role of apostolic journeys in a globalised world, reaffirming the Catholic Church’s commitment to addressing pressing issues on the international stage.

description: The heterogeneous and chaotic nature of osteosarcoma has confounded accurate molecular classification, prognosis, and prediction for this tumor. The occurrence of spontaneous osteosarcoma is largely confined to humans and dogs. While the clinical features are remarkably similar in both species, the organization of dogs into defined breeds provides a more homogeneous genetic background that may increase the likelihood to uncover molecular subtypes for this complex disease. We thus hypothesized that molecular profiles derived from canine osteosarcoma would aid in molecular subclassification of this disease when applied to humans. To test the hypothesis, we performed genome wide gene expression profiling in a cohort of dogs with osteosarcoma, primarily from high-risk breeds. To further reduce inter-sample heterogeneity, we assessed tumor-intrinsic properties through use of an extensive panel of osteosarcoma-derived cell lines. We observed strong differential gene expression that segregated samples into two groups with differential survival probabilities. Groupings were characterized by the inversely correlated expression of genes associated with G2/M transition and DNA damage checkpoint and microenvironment-interaction categories. This signature was preserved in data from whole tumor samples of three independent dog osteosarcoma cohorts, with stratification into the two expected groups. Significantly, this restricted signature partially overlapped a previously defined, predictive signature for soft tissue sarcomas, and it unmasked orthologous molecular subtypes and their corresponding natural histories in five independent data sets from human patients with osteosarcoma. Our results indicate that the narrower genetic diversity of dogs can be utilized to group complex human osteosarcoma into biologically and clinically relevant molecular subtypes. This in turn may enhance prognosis and prediction, and identify relevant therapeutic targets.

description: An on-going effort in the characterization of exoplanetary systems is the accurate determination of host star properties. This effort extends to the relatively bright host stars of planets discovered with the radial velocity method. The Transit Ephemeris Refinement and Monitoring Survey (TERMS) is aiding in these efforts as part of its observational campaign for exoplanet host stars. One of the first known systems is that of 70 Virginis, which harbors a jovian planet in an eccentric orbit. Here we present a complete characterization of this system with a compilation of TERMS photometry, spectroscopy, and interferometry. We provide fundamental properties of the host star through direct interferometric measurements of the radius (1.5\% uncertainty) and through spectroscopic analysis. We combined 59 new Keck HIRES radial velocity measurements with the 169 previously published from the ELODIE, Hamilton, and HIRES spectrographs, to calculate a refined orbital solution and construct a transit ephemeris for the planet. These newly determined system characteristics are used to describe the Habitable Zone of the system with a discussion of possible additional planets and related stability simulations. Finally, we present 19 years of precision robotic photometry that constrain stellar activity and rule out central planetary transits for a Jupiter-radius planet at the 5$σ$ level, with reduced significance down to an impact parameter of $b = 0.95$.

The ‘Tutorless’ Design Studio: A Radical Experiment in Blended Learning
Creators: name: Hill, Glen Andrew
Publisher: name: Journal of Problem Based Learning in Higher Education
Year: 2017

description: This paper describes a pedagogical experiment in which blended learning strategies were used to replace the traditional role of design tutors in a first year architectural design studio. The pedagogical objectives, blended learning strategies and outcomes of the course are detailed. While the quality of the student design work produced by the blended learning design studio was independently assessed as being of a very high standard, the student feedback on the course was mixed. Given the equivocation evident in the student feedback, the paper concludes by speculating on factors beyond the educational strategies that may have led to the high quality of student design work.

description: Bone loss associated with microgravity unloading is well documented; however, the effects of spaceflight-relevant types and doses of radiation on the skeletal system are not well defined. In addition, the combined effect of unloading and radiation has not received much attention. In the present study, we investigated the effect of proton irradiation followed by mechanical unloading via hindlimb suspension (HLS) in mice. Sixteen-week-old female C57BL/6 mice were either exposed to 1 Gy of protons or a sham irradiation procedure (n=30/group). One day later, half of the mice in each group were subjected to four weeks of HLS or normal loading conditions. Radiation treatment alone (IRR) resulted in approximately 20% loss of trabecular bone volume fraction (BV/TV) in the tibia and femur, with no effect in the cortical bone compartment. Conversely, unloading induced substantially greater loss of both trabecular bone (60–70% loss of BV/TV) and cortical bone (approximately 20% loss of cortical bone volume) in both the tibia and femur, with corresponding decreases in cortical bone strength. Histological analyses and serum chemistry data demonstrated increased levels of osteoclast-mediated bone resorption in unloaded mice, but not IRR. HLS+IRR mice generally experienced greater loss of trabecular bone volume fraction, connectivity density, and trabecular number than either unloading or irradiation alone. Although the duration of unloading may have masked certain effects, the skeletal response to irradiation and unloading appears to be additive for certain parameters. Appropriate modeling of the environmental challenges of long duration spaceflight will allow for a better understanding of the underlying mechanisms mediating spaceflight-associated bone loss and for the development of effective countermeasures.

description: We evaluate the forward Compton scattering off the proton, based on Kramers-Kronig kind of relations which express the Compton amplitudes in terms of integrals of total photoabsorption cross sections. We obtain two distinct fits to the world data on the unpolarized total photoabsorption cross section, and evaluate the various spin-independent sum rules using these fits. For the sum of proton electric and magnetic dipole polarizabilities, governed by the Baldin sum rule, we obtain the following average (between the two fits): $α_{E1}+β_{M1}=14.0(2)\times 10^{-4}\,\mathrm{fm}^3$. An analogous sum rule involving the quadrupole polarizabilities of the proton is evaluated too. The spin-independent forward amplitude of proton Compton scattering is evaluated in a broad energy range. The results are compared with previous evaluations and the only experimental data point for this amplitude (at 2.2 GeV). We remark on sum rules for the elastic component of polarizabilities.

description: Animal contest theory assumes individuals to possess accurate information about their own fighting ability or resource-holding potential (RHP) and, under some models, that of their opponent. However, due to the difficulty of disentangling perceived and actual RHP in animals, how accurately individuals are able to assess RHP remains relatively unknown. Furthermore, it is not just individuals within a fight that evaluate RHP. Third-party observers evaluate the fight performance of conspecifics in order to make behavioural decisions. In human combat sports, when fights remain unresolved at the end of the allotted time, bystanders take a more active role, with judges assigning victory based on their assessment of each fighter's performance. Here, we use fight data from mixed martial arts in order to investigate whether perceived fighting performance (judges' decisions) and actual fighting success (fights ending in knock out or submission) are based on the same performance traits, specifically striking skill and vigour. Our results indicate that both performance traits are important for victory, but that vigour is more important for fights resolved via decision, even though the effect of vigour is enhanced by skill. These results suggest that while similar traits are important for fighting success across the board, vigour is overvalued in judges' perceptions of RHP.

description: Cancer progression is often paralleled by a decline in bone mass, raising risk of fracture. Concerns persist regarding anabolic interventions for skeletal protection, as these may inadvertently exacerbate neoplastic tissue expansion. Given bone's inherent mechanosensitivity, low intensity vibration (LIV), a mechanical signal that encourages osteoblastogenesis, could possibly slow cancer-associated bone loss, but this goal must be achieved without fostering disease progression. Seventy 12w female F1-SWRxSWXJ-9 mice, a strain prone to developing granulosa cell tumors, were randomized into baseline control (BC: n=10), age-matched control (AC: n=30), and LIV (n=30), which received mechanical signals (90Hz @ 0.3g) for 15m/d, 5d/w over the course of 1y. Survival curves for AC (10 died) and LIV (8 died) followed similar trends (p=0.62), indicating longevity was unperturbed by LIV. At 1y, bone volume of proximal tibiae in LIV mice was 25% greater than AC (p<0.02), while bone volume of L5 vertebrae was 16% higher in LIV over AC (p<0.02). Primary lesions and peripheral metastases were apparent in both LIV and AC; however, overall tumor incidence was approximately 30% less in LIV (p=0.27) and, when disease was evident, involved fewer organ systems (p=0.09). Marrow-derived mesenchymal stem cells (MSC) were 52% lower (p<0.01) in LIV, and 31% lower (p=0.08) in mice lacking pathology, suggesting higher MSC levels in this model may have contributed to tumor progression. These experiments indicate that LIV helps protect bone mass in mice inherently susceptible to cancer without compromising life expectancy, perhaps through mechanical control of stem cell fate. Further, these data reflect the numerous system-level benefits of exercise in general, and mechanical signals in particular, in the preservation of bone density and the suppression of cancer progression.
