title: Modeling Affordable Housing in Moab and Spanish Valley
Creators: name: Starley, Matthew
Publisher: name: Utah State University
Year: 2019

description: The Colorado Plateau region of southeastern Utah is geographically unique. Iconic sandstone geological formations, such as the famous Delicate Arch, which adorns Utah license plates, dot the landscape. This beautiful environment has inspired the formation of national and state parks, as well as a multitude of diverse recreation areas.
Affordable housing in Moab and Spanish Valley is a key issue for the development of the valley. This has been well documented by the Moab Area Housing Task Force (MAHTF) in its 2017 Moab Area Affordable Housing Plan. This Plan B Thesis Project builds on the work of the task force, by documenting efforts to address where and how affordable housing might be located in the valley.
In order to develop consensus around the location of affordable housing, a geodesign workshop was sponsored and hosted by the task force, and prepared and facilitated by Barty Warren-Kretzschmar and Matthew Starley. In the scope of the following thesis, using Geodesignhub software, stakeholders in the area gathered to identified areas where housing might be located.
Workshop results were analyzed in order to identify a priority focus area for locating affordable housing, and from those results, a priority focus area for locating affordable housing was identified by the MAHTF. Three design concepts for this area have been created that integrate the results of the workshop as well as the results of a study of design strategies and housing typologies appropriate for Moab and Spanish Valley.

description: Emission lines from metals offer one of the most promising ways to detect the elusive warm-hot intergalactic medium (WHIM; 10^5 K10^6 K). We find that the OVIII 18.97A is the strongest emission line, with a predicted maximum surface brightness of ~10^2 photon/s/cm^2/sr, but a number of other lines are only slightly weaker. All lines show a strong correlation between the intensity of the observed flux and the density and metallicity of the gas responsible for the emission. On the other hand, the potentially detectable emission consistently corresponds to the temperature at which the emissivity of the electronic transition peaks. The emission traces neither the baryonic nor the metal mass. In particular, the emission that is potentially detectable with proposed missions, traces overdense (rho>10^2rho_mean) and metal-rich (Z>0.1Z_sun) gas in and around galaxies and groups. While soft X-ray line emission is therefore not a promising route to close the baryon budget, it does offer the exciting possibility to image the gas accreting onto and flowing out of galaxies.

description: The interactions between radio jets and the interstellar medium play a defining role for the co-evolution of central supermassive black holes and their host galaxies, but observational constraints on these feedback processes are still very limited at redshifts $z > 2$. We investigate the radio-loud quasar PSO J352.4034-15.3373 at $z \sim 6$ at the edge of the Epoch of Reionization. This quasar is among the most powerful radio emitters and the first one with direct evidence of extended radio jets ($\sim$1.6 kpc) at these high redshifts. We analyze NOEMA and ALMA millimeter data targeting the CO (6-5) and [CII] far-infrared emission lines, respectively, and the underlying continuum. The broad $440\pm 80$ km s$^{-1}$ and marginally resolved [CII] emission line yields a systemic redshift of $z\!=\!5.832 \pm 0.001$. Additionally, we report a strong 215 MHz radio continuum detection, $88\pm 7$ mJy, using the GMRT. This measurement significantly improves the constraints at the low-frequency end of the spectral energy distribution of this quasar. In contrast to what is typically observed in high-redshift radio-quiet quasars, we show that cold dust emission alone cannot reproduce the millimeter continuum measurements. This is evidence that the strong synchrotron emission from the quasar contributes substantially to the emission even at millimeter (far-infrared in the rest-frame) wavelengths. This quasar is an ideal system to probe the effects of radio jets during the formation of a massive galaxy within the first Gyr of the Universe.

Minimum seismic requirements for masonry walls
Creators: name: Chung, Rufus Wai-Kwong
Publisher: name: University of British Columbia
Year: 2010

description: A study by computer analysis was conducted to establish the minimum percentage of steel required in the seismic design of masonry walls with respect to transverse forces. Buildings of masonry load-bearing shear wall and masonry infill-frame construction were studied. The buildings were modelled as plane frame structures. Linear elastic spectral analyses were performed by using the modified computer program DYNAMIC. By examining the response of the models to a peak ground acceleration of 1.0 g, a correlation between the fundamental period of a masonry wall structure and its response accelerations at different height is found, i.e., envelopes of dynamic amplication factor are developed. A new empirical formula for estimating the fundamental period of a structure with masonry walls is recommended. The minimum steel is established in typical wall panels designed for the inertia forces imposed by a major earthquake in seismic Zone 3.

description: Type IIA string theory compactified on a Calabi-Yau threefold has a hypermultiplet moduli space whose metric is known to receive non-perturbative corrections from Euclidean D2-branes wrapped on 3-cycles. These corrections have been computed earlier by making use of mirror symmetry, S-duality and twistorial description of quaternionic geometries. In this paper we compute the leading corrections in each homology class using a direct world-sheet approach without relying on any duality symmetry or supersymmetry. Our results are in perfect agreement with the earlier predictions.

title: The Effects of a Yoga Intervention on Reactive Balance in Older Adults
Creators: name: Hayes, Haley M
Publisher: name: Utah State University
Year: 2019

description: Research into successful aging has shown that the ability to control balance is a key part of maintaining an independent lifestyle. Given the increased proportion of older adults in society, the development of effective strategies to promote successful aging are critical. One promising form of activity that could effectively sustain and/or improve balance in addition to other health markers is yoga. Although studies have been done showing yoga's benefits on mobility, mood and cognition the vast majority of these studies lack scientific rigor. The main purpose of this thesis project was to examine the efficacy of a 6-week yoga intervention in improving reactive balance in older adults. This study is one part of a larger intervention study that investigated changes in cognitive function and muscle strength in addition to balance. Thirteen older adults were randomized into a yoga intervention group (n=7) or a control group (n=6). Subjects in the yoga group participated in hour long classes, twice per week for six weeks. Each yoga class incorporate seated, standing and lying down poses along with breathwork and meditation. Subjects in the control group completed hour long sessions of computer-based cognitive training twice per week for six weeks. Reactive balance was tested using a custom lean and release device both before and after the intervention. Balance performance was measured as: (a) muscle onset time in the stepping leg, when a forward step was required to recover balance, and (b) stepping errors (i.e. taking a step when the leg was blocked). No statistically significant effects were noted between groups on response time (p = 0.447) nor error rate (p = 0.622). However, the low sample size likely compromises our ability to make definitive conclusions. This study is an early attempt to get very focused measures to evaluate yoga, using a balance task that emphasized heightened cognitive demand. With this study we were able to demonstrate the feasibility of using yoga as an intervention and provide insight for future studies looking at the potential effects of yoga on reactive balance in older adults.
title: Organization of a Community Garden Program through Utah State University Food $ense and Master Gardener Extension Programs for Low-Income Families in Logan, Utah
Creators: name: Hendrickson, Jackie
Publisher: name: Utah State University
Year: 2019

description: Nearly 12.3% of American households are food insecure. In Cache County, Utah, specifically, the rates of food insecurity are even higher (15%). Addressing the issue of food insecurity improves physical/mental health outcomes, childhood cognitive/physical development, family environments, and decreases healthcare costs. Evidence-based strategies to improve food security include increasing one’s access to fresh fruits and vegetables and improving self-efficacy. Community gardens are recognized as an initiative that improve participant’s levels of food security. In Utah, a number of community gardens exist, but none focus on food insecure individuals or include a curriculum of basic gardening and nutrition skills. Utah State University’s Food $ense and Master Gardener programs partnered together to create a community gardening program targeting low-income families in Cache Valley, Utah. The Create Farm Fresh Gardens program was developed with the aim of improving levels of food security through increased access to fresh vegetables and improved feelings of self-efficacy in regard to gardening and nutrition among participants. The Create Farm Fresh Gardens program was piloted in Cache Valley, Utah during the 2018 growing season and received supportive feedback from participants. The program will be implemented throughout the state of Utah during the 2019 growing season.

description: We consider the 1-loop correction to the energy of folded spinning string solution in the AdS_3 part of AdS_5 x S^5. The classical string solution is expressed in terms of elliptic functions so an explicit computation of the corresponding fluctuation determinants for generic values of the spin appears to be a non-trivial problem. We show how it can be solved exactly by using the static gauge expression for the string partition function (which we demonstrate to be equivalent to the conformal gauge one) and observing that all the corresponding second order fluctuation operators can be put into the standard (single-gap) Lamé form. We systematically derive the small spin and large spin expansions of the resulting expression for the string energy and comment on some of their applications.

The large obliquity of Saturn explained by the fast migration of Titan

description: The obliquity of a planet is the tilt between its equator and its orbital plane. Giant planets are expected to form with near-zero obliquities. After its formation, some dynamical mechanism must therefore have tilted Saturn up to its current obliquity of 26.7°. This event is traditionally thought to have happened more than 4 Gyrs ago during the late planetary migration because of the crossing of a resonance between the spin-axis precession of Saturn and the nodal orbital precession mode of Neptune. Here, we show that the fast tidal migration of Titan measured by Lainey et al. (2020) is incompatible with this scenario, and that it offers a new explanation for Saturn's current obliquity. A significant migration of Titan would prevent any early resonance, invalidating previous constraints on the late planetary migration set by the tilting of Saturn. We propose instead that the resonance was encountered recently, about 1 Gyr ago, forcing Saturn's obliquity to increase from a small value (possibly less than 3°), up to its current state. This scenario suggests that Saturn's normalised polar moment of inertia lies between 0.224 and 0.237. Our findings bring out a new paradigm for the spin-axis evolution of Saturn, Jupiter, and possibly giant exoplanets in multiple systems, whereby obliquities are not settled once for all, but continuously evolve as a result of the migration of their satellites.

title: “Get Tough!”: A Case Study on the Development of the Sport Ethic in Youth Lacrosse
Creators: name: Budziszewski, Ross
Publisher: name: Utah State University
Year: 2019

description: While participation in youth sport is often linked with positive psychosocial and physical outcomes (Holt et al., 2017), this context can also cultivate ideals that lead to the development of unethical beliefs as well as unsafe sport practices (Al-Yaarbi & Kavussanu, 2017). The sport ethic is described as the deviant overconformity by an athlete to fit societal expectations of a sport’s high-performance culture (Hughes & Coakley, 1991). Strong beliefs in the sport ethic can lead to moral disengagement, antisocial behavior, and viewing sport like warfare (Shields, Funk, & Bredemeier, 2015). Although the sport ethic has been examined in competitive adult sport (Coakley, 2015), the development of this belief system among youth remains relatively unexplored. Utilizing Bronfenbrenner’s (1986) ecological systems theory of development, the present study employed a case study approach to investigate the cultivation of the sport ethic in a recreational youth lacrosse team over the course of a four-month competitive season. Data were collected through 109 hours of naturalistic observation (during seven games and 27 practice sessions) and semi-structured interviews with four athletes and one parent. Data were analyzed using a general thematic analysis approach (Braun & Clarke, 2006). Key themes from the microsystem level (i.e., athletes, parents, peers, coaches) highlight that an overemphasis on masculinity, specialization, and sacrifice may predispose athletes to internalize deviant ideals of the sport ethic, even if one’s mesosystem (i.e., the sport’s organization) discourages such behavior. Findings draw attention to the social factors (e.g., promoting lacrosse as a “man’s game” or encouraging violent play) in youth sporting contexts that may impact the development of unsafe practices (e.g., playing through injury, hurting opponents), and provide practical implications for youth sport coaches, parents, and athletes by creating an environment where safe sport practices are encouraged.

Nearly round surfaces can be defined in an intrinsic way. Our results show that the ADM mass of an asymptotically flat 3-manifold can be approximated by some geometric invariants of a family of nearly round surfaces which approach to infinity of the manifold.

Fisheries resource maintenance flows for Pacific salmon
Creators: name: Hamilton, Roy Ernest
Publisher: name: University of British Columbia
Year: 2010

description: The statutory background of water use and the conflict with instream uses is reviewed. Habitat criteria for the several phases — migration, spawning, incubation, and rearing — of the fresh water life cycle of salmon are provided. Stream channel morphology and hydraulics are discussed, relative to salmon habitat requirements and the determination of fisheries resource maintenance flows. The relationship Between watershed hydrology and the fresh water life cycle of salmon is described, and techniques, with, examples, are given for analysing low flows for gaged and ungaged watersheds. Some of the more recent methodologies for establishing Fisheries Resource Maintenance Flows are reviewed and a new technique, using the utility curve concept to combine qualitative and quantitative information, is introduced. The advantages of this technique are that definite incremental values of potential productivity can be determined for a series of flow levels, based on either empirical data or expert opinion, or a combination of both, for subsequent resource evaluation and decision making. A step by step procedure is given for establishing Fisheries Resource Maintenance Flows, and some of the aspects of water management pertaining to recognition of instream flow requirements are addressed.

description: A very simple and physical derivation of the conservation equation for the propagation of gravitational radiation is presented. The formulation is exact. The result takes the readily recognisable and intuitive form of a Poynting-style equation, in which the outward propagation of stress-energy is directly related to the volumetric equivalent of a radiation reaction force acting back upon the sources, including the purely gravitational contribution to the sources. Upon averaging, the emergent pseudo tensor for the gravitational radiation is in exact agreement with that found by much more labour-intensive methods.

description: Fabrication of large area (sub 1 cm cross-section) micro-optical components in a short period of time (approximately 10 min) and with lesser number of processing steps is highly desirable and cost-effective. In the recent years, femtosecond laser fabrication technology has revolutionized the field of manufacturing by offering the above capabilities. In this study, a fundamental diffractive optical element, binary axicon i.e axicon with two phase or amplitude levels, has been designed in three configurations namely conventional axicon, photon sieve axicon (PSA) and sparse PSA and directly milled onto the Sapphire substrate. The fabrication results revealed that a single pulse burst fabrication can produce a flat and smooth profile than pulse overlapped fabrication which gives rise to surface damage and increased roughness. The fabricated elements were processed in IsoPropyl Alcohol and Potassium Hydroxide to remove debris and redeposited amorphous Sapphire. An incoherent illumination was used for optical testing of the components and a non-linear optical filter was used for cleaning the noisy images generated by the diffractive optical elements.

Publisher: name: Utah State University

description: A-mode ultrasound is a noninvasive and rapid method for measuring subcutaneous fat thickness and estimating body fat percentage (%BF). The validity and reliability of the BodyMetrix BX2000 A-mode ultrasound has been reported; however, the purpose of this study was to compare results from two machines to determine interdevice reliability. Ultrasound measures were repeated with two BX2000 machines at 10 body sites (chest, biceps, triceps, scapula, lower back, hip, waist, thigh, calf, axilla) on 42 males of varying age and leanness (age: 28.6 ± 11.9 y, BMI: 25.4 ± 4.6 kg/m2). The intraclass correlation coefficients ranged from 0.939 to 0.998 with standard errors of measurement from 0.31 to 0.58 mm of fat thickness. The only statistically significant difference (p < 0.001) between devices was at the chest (0.33 mm) and scapula (0.37 mm). However, there was no difference between machines in the estimation of %BF (0.34%BF; p = 0.09). The interdevice reliability is similar to the previously reported test-retest reliability with no clinical significance between the two machines.
Application of auto regressive filtering techniques to flood flow prediction
Creators: name: Cahoon, Peter G.
Publisher: name: University of British Columbia
Year: 2010

description: This thesis describes a study of the application of multichannel deconvolution, an autoregressive filtering technique, to the problems of flood flow prediction. This application is divided into four component segments: 1. The description of the behaviour of a multiple input, multiple output basin using multichannel autoregressive techniques with multiple lags of finite length. These descriptions fall into two catagories: a) the Weiner autoregressive technique₇. b) minimum entropy auto regression₁₃. 2. The restatement of the input/output problem as a time varying state-space description with a feedback mechanism for implementation of information having a unit time delay. 3. The analysis and characterization of the state-space and autoregressive methods using standard spectral analysis techniques and statistical confidence limits. 4. The linking of the state-space/autoregression characterizations for snowpack depletion and rainfall/runoff into a finite state machine algorithm coalescing the two processes so they may be linked to satellite information. Several case studies were used in which the multiple precipitation records and multiple flow records were characterized. These steady state characteristics were then updated using the Kalman state-space description to provide an "online"₁, information update. The snowpack depletion problem was treated as a multiple input (rainfall, temperature, humidity), single output (snowmelt) phenomena and characterized by a single multichannel autoregression. A second class of characterizations was employed to cope with the "spike" arrivals caused by rapid snowmelt flowing into a single output. This minimum entropy₁₃ technique is developed for "flash flood" prediction. Finally, a finite state machine algorithm is developed to link the snowpack depletion to the rainfall runoff problem in such a way that it can be readily linked to satellite produced data streams. For those unfamiliar with the complex and obtuse language of deconvolution and control theory, the role of this thesis can be described by analogy: You have arrived in the middle of a party where the participants are all quite intoxicated. They are huddled together in small knots talking excitedly, but without much clarity about decon operators, M.E.D. processes, frames and finite state machines. My role is to catch you up on the conversation and help you find your way to the bar.

description: Many benefits of online communities---such as obtaining new information, opportunities, and social connections---increase with size. Thus, a ``successful'' online community often evokes an image of hundreds of thousands of users, and practitioners and researchers alike have sought to devise methods to achieve growth and thereby, success. On the other hand, small online communities exist in droves and many persist in their smallness over time. Turning to the highly popular discussion website Reddit, which is made up of hundreds of thousands of communities, we conducted a qualitative interview study examining how and why people participate in these persistently small communities, in order to understand why these communities exist when popular approaches would assume them to be failures. Drawing from twenty interviews, this paper makes several contributions: we describe how small communities provide unique informational and interactional spaces for participants, who are drawn by the hyperspecific aspects of the community; we find that small communities do not promote strong dyadic interpersonal relationships but rather promote group-based identity; and we highlight how participation in small communities is part of a broader, ongoing strategy to curate participants' online experience. We argue that online communities can be seen as nested niches: parts of an embedded, complex, symbiotic socio-informational ecosystem. We suggest ways that social computing research could benefit from more deliberate considerations of interdependence between diverse scales of online community sizes.

description: Any compact spacelike hypersurface immersed in a doubly warped product spacetime $I{}_{h} \times_ρ \mathbb{P}$ with nondecreasing warping factor $ρ$ must be a spacelike slice, provided that the mean curvature satisfies $H\geqρ'/hρ$ everywhere on the hypersurface. The conclusion also holds, under suitable assumptions on the immersion, when the hypersurface is complete and noncompact. A similar rigidity property is shown for compact hypersurfaces in spacetimes carrying a conformal, strictly expanding, timelike vector field.

description: In this paper we study a new product of graphs called {\em tight product}. A graph $H$ is said to be a tight product of two (undirected multi) graphs $G_1$ and $G_2$, if $V(H)=V(G_1)\times V(G_2)$ and both projection maps $V(H)\to V(G_1)$ and $V(H)\to V(G_2)$ are covering maps. It is not a priori clear when two given graphs have a tight product (in fact, it is $NP$-hard to decide). We investigate the conditions under which this is possible. This perspective yields a new characterization of class-1 $(2k+1)$-regular graphs. We also obtain a new model of random $d$-regular graphs whose second eigenvalue is almost surely at most $O(d^{3/4})$. This construction resembles random graph lifts, but requires fewer random bits.

description: We consider the basic physical properties of matter forming a thin accretion disc in the static and spherically symmetric space-time metric of the vacuum $f(R)$ modified gravity models. The Lagrangian of the generalized gravity theory is also obtained in a parametric form, and the conditions of the viability of the model are discussed. The exact Schwarzschild type solution of the gravitational field equations in the $f(R)$ gravity contains a linearly increasing term, as well as a logarithmic correction, as compared to the standard Schwarzschild solution of general relativity, and it depends on four arbitrary integration constants. The energy flux and the emission spectrum from the accretion disk around the $f(R)$ gravity black holes are obtained, and they are compared to the general relativistic case. Particular signatures can appear in the electromagnetic spectrum, thus leading to the possibility of directly testing modified gravity models by using astrophysical observations of the emission spectra from accretion disks.

description: The response of hadrons to electromagnetic probes is highly constrained by chiral dynamics; but, in some cases, predictions have not compared well with experimental data. The lattice can be used to test the chiral electromagnetism of hadrons and ultimately confront experiment. We use background field techniques to study the electromagnetic polarizabilities of hadrons. Focusing on simulations in background electric fields, we present preliminary results for both charged and neutral particle polarizabilities. The former are extracted using a novel method.

description: We consider a one-dimensional (1D) structure where non-interacting spin-$s$ scattering centers, such as quantum impurities or multi-level atoms, are embedded at given positions. We show that the injection into the structure of unpolarized flying qubits, such as electrons or photons, along with {path} detection suffice to accomplish spin-state teleportation between two centers via a third ancillary one. {No action over the internal quantum state of both the spin-$s$ particles and the flying qubits is required. The protocol enables the transfer of quantum information between well-seperated static entities in nanostructures by exploiting a very low-control mechanism, namely scattering.

description: Let $W$ be a Weyl group, and let $\CT_W$ be the complex toric variety attached to the fan of cones corresponding to the reflecting hyperplanes of $W$, and its weight lattice. The real locus $\CT_W(\R)$ is a smooth, connected, compact manifold with a $W$-action. We give a formula for the equivariant Euler characteristic of $\CT_W(\R)$ as a generalised character of $W$. In type $A_{n-1}$ for $n$ odd, one obtains a generalised character of $\Sym_n$ whose degree is (up to sign) the $n^{\text{th}}$ Euler number.

description: Through the General Data Protection Regulation (GDPR), the European Union has set out its vision for Automated Decision- Making (ADM) and AI, which must be reliable and human-centred. In particular we are interested on the Right to Explanation, that requires industry to produce explanations of ADM. The High-Level Expert Group on Artificial Intelligence (AI-HLEG), set up to support the implementation of this vision, has produced guidelines discussing the types of explanations that are appropriate for user-centred (interactive) Explanatory Tools. In this paper we propose our version of Explanatory Narratives (EN), based on user-centred concepts drawn from ISO 9241, as a model for user-centred explanations aligned with the GDPR and the AI-HLEG guidelines. Through the use of ENs we convert the problem of generating explanations for ADM into the identification of an appropriate path over an Explanatory Space, allowing explainees to interactively explore it and produce the explanation best suited to their needs. To this end we list suitable exploration heuristics, we study the properties and structure of explanations, and discuss the proposed model identifying its weaknesses and strengths.
title: The Effects of Student Learning When Subtitles are Added to Videos

Publisher: name: Utah State University

description: This project investigated whether adding subtitles to educational videos increases learning among middle school students. A convenience sample (N=387) of Technology and Engineering middle school students were separated into two groups during the third term of both the 2018 and 2019 school years, where one group of students viewed videos with subtitles and the other group viewed the identical videos without subtitles. After viewing the videos, students immediately took a multiple-choice test. The test scores were used to analyze the variance between the two different groups. The results reveal that students who viewed videos with subtitles had slightly lower scores than those who viewed the videos without subtitles. This project seems to indicate that viewing videos with subtitles does not improve learning more than viewing videos without subtitles among middle school students in a general class setting.
title: Staying Upright by Shutting Down? Evidence for Global Suppression of the Motor System When Recovering Balance
Creators: name: Goode, Caleigh
Publisher: name: Utah State University
Year: 2019

description: Background: When automatic, yet unwanted action is quickly inhibited, short-lived suppression throughout the motor system ensues. This type of response inhibition causing an all-over motor suppression effect is referred to as global suppression. Although response inhibition is essential for behavioral flexibility, widespread motor suppression may delay action reprogramming. In reactive balance control, even fleeting suppression of the motor system could interfere with our ability to adapt compensatory reactions quickly enough to avoid a fall.Whether this concept of global suppression is occurring in situations that pose a postural threat is undetermined.
Research Question: Is muscle activity in the hand suppressed when a pre-potent compensatory step becomes suddenly blocked in a balance recovery task?
Methods: Nineteen young adults were tested using a lean and release apparatus. Participants were occasionally released from a support cable resulting in forward body displacement. At the start of each trial, vision was occluded and a leg block was either placed in front of the legs or removed to allow a forward step. After goggles opened, the cable was released to cause a postural perturbation and participants had to either quickly step forward (STEP) or use a feet-in-place reaction to regain stability (NO-STEP). Step trials were much more frequent to promote stepping. Transcranial magnetic stimulation (TMS) was delivered shortly after receving vision (but before postural perturbation) to assess corticospinal excitability in an intrinsic hand muscle that was irrelevant to the balance recovery task.
Results: Repeated measures ANOVA compared motor-evoked potentials across two step conditions (STEP, NO-STEP) and two TMS latencies (100ms, 200ms). The time x step condition interaction was significant with (F(1,18) = 4.47, p = 0.049). The resultant interaction provided evidence of motor suppression in the hand when a forward step was blocked.
Significance: Inhibition of a hand muscle uninvolved in a compensatory leg response provided evidence of global suppression in a whole-body, reactive balance context. Such widespread suppression of the motor system has implications for maintaining postural equilibrium, where even a momentary shutdown across body regions could interfere with the ability to adapt corrective balance reactions.
title: A Swimming Open-Water Navigation Assistive Headset and Receiver

description: Open water swimming is a common activity dating back to ancient times. One challenge with open water swimming is navigation because while maintaining proper swimming technique suggests the head be in the water, it is difficult to see where one is going. Thus swimmers must bring their head out of the water periodically to sight landmarks. This work describes a solution to this problem by a design for a GPS device to assist swimmers with navigation. The swimmer can plan their own route, send it to the device, and then be guided by the device. They then will not have to bring their head out of the water to look for landmarks and can save energy for swimming.
