description: The BEST wide-angle telescope installed at the Observatoire de Haute-Provence and operated in remote control from Berlin by the Institut fuer Planetenforschung, DLR, has observed the CoRoT target fields prior to the mission. The resulting archive of stellar photometric lightcurves is used to search for deep transit events announced during CoRoT's alarm-mode to aid in fast photometric confirmation of these events. The "initial run" field of CoRoT (IRa01) has been observed with BEST in November and December 2006 for 12 nights. The first "long run" field (LRc01) was observed from June to September 2005 for 35 nights. After standard CCD data reduction, aperture photometry has been performed using the ISIS image subtraction method. About 30,000 lightcurves were obtained in each field. Transits of the first detected planets by the CoRoT mission, CoRoT-1b and CoRoT-2b, were found in archived data of the BEST survey and their lightcurves are presented here. Such detections provide useful information at the early stage of the organization of follow-up observations of satellite alarm-mode planet candidates. In addition, no period change was found over ~4 years between the first BEST observation and last available transit observations.

description: Demand for tourist activities related to natural spaces and wildlife has increased over recent years. This paper analyses the influence of socio-demographic and travel indicators on international demand for such tourism in Costa Rica. Using discrete choice models, a range of principal activities is studied: hiking, visits to volcanoes, observation of flora and fauna, bird-watching and canoeing. The results show the favourable influence on demand of variables such as family, travel with partners and country of origin, providing orientation for policies and strategies of the nature-based tourism in Costa Rica, as well as indicators for other countries interested in developing this sector.

title: Spatial Ability Degradation in Undergraduate Mechanical Engineering Students During the Winter Semester Break
Creators: name: Call, Benjamin J.
Publisher: name: Utah State University
Year: 2018

description: Spatial ability represents our ability to mentally arrange, rotate, and explore objects in multiple dimensions. This ability has been found to be important for engineers and engineering students. Past research has shown that many interventions can be created to boost an individual’s spatial ability. In fact, past research has indicated that engineering students significantly increase in spatial ability without an intervention while they are enrolled in certain engineering courses. Some researchers have claimed that the spatial ability boosts are permanent after an intervention. However, most researchers do not check the validity of that claim with continued assessment after more than a week past the end of an intervention. Additionally, if engineering education researchers are trying to measure the impact of their separate spatial ability intervention while the participating engineering students are actively enrolled in engineering courses, a confounding variable is introduced as the courses can impact students’ spatial ability. To resolve this, the work presented in this paper reflects research on engineering students’ spatial ability maintenance during the winter break between semesters. It was found that newer students exhibit spatial ability improvement during the break, while older students maintain their spatial ability at the same level. A deeper statistical analysis revealed that there are other factors that play a role in spatial ability changes over the break that are more significant than how far students had progressed in their studies. Those factors include with academic performance, the sex of the students, playing music during the break, and prior life experiences.

description: We study the field theory localizing to holomorphic maps from a complex manifold of complex dimension 2 to a toric target (a generalization of A model). Fields are realized as maps to $(\mathbb{C}^*)^N$ where one includes special observables supported on (1,1)-dimensional submanifolds to produce maps to the toric compactification. We study the mirror of this model. It turns out to be a free theory interacting with $N_\mathrm{comp}$ topological strings of type A. Here $N_\mathrm{comp}$ is the number of compactifying divisors of the toric target. Before the mirror transformation these strings are vortex (actually, holomortex) strings.

description: The purpose of this research is to test the tourist’s perception in the choice of selection a destination under the perspective of Bangladeshi tourism environment. The survey instrument was employed by using convenience sampling procedure on 250 tourists from significant tourist’s destination places from Bangladesh. Exploratory factor analysis (EFA) followed by Confirmatory factor analysis (CFA) was used to test the key influential attributes. Apart from that structural equation model was also used to test the hypothesis of this study. The result shows that most of the tourists perceived that selection of a destination highly depend on destination brand image, internet adoption followed by customer’s satisfaction. This research will assist the operators of tourism industry in Bangladesh to understand the influential factors which are influencing tourist’s perception to choose a destination that is unexplored previously by the past researchers.

description: Non-Abelian states of matter, in which the final state depends on the order of the interchanges of two quasiparticles, can encode information immune from environmental noise with the potential to provide a robust platform for topological quantum computation. We demonstrate that phonons can carry non-Abelian frame charges at the band crossing points of their frequency spectrum, and that external stimuli can drive their braiding. We present a general framework to understand the topological configurations of phonons from first principles calculations using a topological invariant called Euler class, and provide a complete analysis of phonon braiding by combining different topological configurations. Taking a well-known dielectric material, Al$_2$O$_3$, as a representative example, we demonstrate that electrostatic doping gives rise to phonon band inversions that can induce redistribution of the frame charges, leading to non-Abelian braiding of phonons. Our work provides a new quasiparticle platform for realizable non-Abelian braiding in reciprocal space, and expands the toolset for studying braiding processes.

description: Creating a local identity through clustering of attractions, services and products in a region seems to be the contemporary answer in maintaining economic and social viability. Despite the growing interest in tourism clusters, it is still a field that remains unexplored especially in rural areas which have additional drawbacks to entrepreneurship. In this paper we will focus on the development of tourism clusters within the framework of Community Initiative LEADER+ in rural areas in Greece. Both qualitative and quantitative data from several case studies of clustering in Northern Greece and a survey on 110 cluster members are used to answer our basic research questions. Evidence from our study suggest that those tourism clusters are locally and socially embedded, are driven from different networking norms and levels of trust amongst members and are in need of motivation, encouragement and assistance from local stakeholders.

description: Smartphones have become the most used electronic devices. They carry out most of the functionalities of desktops, offering various useful applications that suit the users needs. Therefore, instead of the operator, the user has been the main controller of the device and its applications, therefore its reliability has become an emergent requirement. As a first step, based on collected smartphone applications failure data, we investigated and evaluated the efficacy of Software Reliability Growth Models (SRGMs) when applied to these smartphone data in order to check whether they achieve the same accuracy as in the desktop/laptop area. None of the selected models were able to account for the smartphone data satisfactorily. Their failure is traced back to: (i) the hardware and software differences between desktops and smartphones, (ii) the specific features of mobile applications compared to desktop applications, and (iii) the different operational conditions and usage profiles. Thus, a reliability model suited to smartphone applications is still needed. In the second step, we applied the Weibull and Gamma distributions, and their two particular cases, Rayleigh and S-Shaped, to model the smartphone failure data sorted by application version number and grouped into different time periods. An estimation of the expected number of defects in each application version was obtained. The performances of the distributions were then compared amongst each other. We found that both Weibull and Gamma distributions can fit the failure data of mobile applications, although the Gamma distribution is frequently more suited.

description: The spiders of Theridiidae's family display a peculiar behaviour when they hunt extremely large prey. They lift the quarry, making it unable to escape, by attaching pre-tensioned silk threads to it. In this work, we analysed for the first time in the laboratory the lifting hunting mechanism and, in order to quantify the phenomenon, we applied the lifting mechanics theory. The comparison between the experiments and the theory suggests that, during the process, spider does not stretch the silk too much by keeping it in the linear elastic regime. We thus report here further evidence for the strong role of silk in spiders' evolution, especially how spiders can stretch and use it as an external tool to overcome their muscles’ limits and capture prey with large mass.

description: The aim of this study is to investigating participation levels of hotel employees in the dimensions of strategic human resources management. To achieve this, we present to what extent hotel employees participated in the dimensions of strategic human resources management. The success of hotel business in undertaking the wishes and expectations of its employees will motivate them and will contribute to the managers and companies. The research data was derived from employees working full-time shifts in a five-star hotel. At the end of the research, it’s stated that most of the employees participated in the dimensions of strategic human resources management. However, it’s determined that most of the employees had a middle level participation according to the statements that produce the dimensions strategic human resources management. As a result, it’s deduced that employees in hotels care about the dimensions of strategic human resources management and participate in them. The fact that the data was gathered from only one five-star hotel is an important constraint of this study.

description: The propagation of several spatial modes has a significant impact on the structure of the emission from parametric down-conversion in a nonlinear waveguide. This manifests itself not only in the spatial correlations of the photon pairs but also, due to new phase-matching conditions, in the output spectrum, radically altering the degree of entanglement within each pair. Here we investigate both theoretically and experimentally the results of higher-order spatial-mode propagation in nonlinear waveguides. We derive conditions for the creation of pairs in these modes and present observations of higher-order mode propagation in both the spatial and spectral domains. Furthermore, we observe correlations between the different degrees of freedom and finally we discuss strategies for mitigating any detrimental effects and optimizing pair production in the fundamental mode.

Year: 2009
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: The Letter takes up a question of what radio emission is produced by electrons at the very acceleration site of a solar flare. Specifically, we calculate incoherent radio emission produced within two competing acceleration models--stochastic acceleration by cascading MHD turbulence and regular acceleration in collapsing magnetic traps. Our analysis clearly demonstrates that the radio emission from the acceleration sites: (i) has sufficiently strong intensity to be observed by currently available radio instruments and (ii) has spectra and light curves which are distinctly different in these two competing models, which makes them observationally distinguishable. In particular, we suggest that some of the narrowband microwave and decimeter continuum bursts may be a signature of the stochastic acceleration in solar flares.

description: Wild grapevine – Vitis vinifera subsp. sylvestris – ancestors of cultivated grapevines are the main players in understanding the molecular bases of the grapevine domestication process. The goal of the presented research was to assess the genetic diversity of wild grapevine samples from several regions encompassing Europe (Spain, France, Germany, Hungary, Greece), the Mediterranean basin (Algeria, Tunisia, Morocco), and South Caucasus (Georgia), using a complete chloroplast DNA sequencing. The results suggest the existence of three different chloroplast DNA haplotypes, reflecting the geographical distribution of the analyzed samples. This study represents the first report focused on analysis of a wide range of wild grapevine samples (Vitis vinifera subsp. sylvestris), applying next-generation technologies, and tracing the grapevine ancestry.

description: Plants absorb CO2 through pores in their leaves called stomata, which are known to open and close in response to myriad environmental and physiological triggers. We demonstrate that blue light inhibits stomatal aperture oscillations in both the guard cells and surrounding tissue layers, whereas these oscillations continue under the influence of red light. This observation of blue light behavior agrees with recent research and suggests another physiological pathway for oscillations.
title: Development of an Improved Low-Order Model for Propeller-Wing Interactions
Creators: name: Goates, Joshua Taylor
Publisher: name: Utah State University
Year: 2018

description: For aircraft that have propellers mounted in front of the wings or tail, the prop wash produced by the propellers can have a strong influence on the aerodynamics of the aircraft. As the accelerated air from the propeller flows over the wings and tail, it can cause an alteration in the aerodynamic forces produced by those surfaces. Thus, an understanding of propeller-wing interactions is essential for the design and analysis of many aircraft.
There are multiple existing methods for analyzing the propeller-wing interactions. High order methods, such as wind tunnel testing or computational fluid dynamics, provide very accurate results but come at a high cost in computation or labor. Low-order methods provide results with good accuracy at a significantly lower cost. Thus, it is desirable to use low-order methods for initial design and utilize higher order methods closer to the end of the design phase.
Current low-order models for propeller-wing interactions give reasonable results, but have shortcomings in either computational cost or accuracy. In an effort to improve on these existing models, an improved low-order model for propeller-wing interactions is proposed. This improved model utilizes several aerodynamic models such as blade element theory and lifting line theory as well as a novel turbulent prop wash model. The final model is shown to provide more accurate results using efficient numerical methods.
title: The Macroinvertebrate and Fish Communities of In-Stream Beaver Ponds in Northeastern Utah
Creators: name: Washko, Susan
Publisher: name: Utah State University
Year: 2018

description: Beavers were virtually extirpated from North America during the fur trade, but populations have since recovered. Dams built by recolonizing beaver alter stream habitat by forming deep, slow ponds within the streams. Such changes to the habitat is likely to have consequences for organisms such as macroinvertebrates and fish. The objective of this study was to identify the differences in the macroinvertebrate and trout community in beaver ponds and lotic (e.g. flowing reaches of a stream) reaches in tributaries to the Logan River in northeastern Utah. The macroinvertebrate community of beaver ponds had fewer species, fewer numbers, and lower biomass of macroinvertebrates compared to lotic reaches. Macroinvertebrates that consume leaf litter and predators that prey on other macroinvertebrates characterized beaver pond macroinvertebrate communities. In contrast, lotic reaches contained macroinvertebrates that consume algae and feed on particles floating through the water column. Macroinvertebrates in lotic reaches were morphologically adapted to cling to rocks in the streamflow, while those in beaver ponds were adapted to living within the fine sediment.
Bonneville cutthroat trout collected from lotic reaches were larger than those collected from beaver ponds, while the opposite was true for brown trout collected from lotic reaches. I also found that short-term and long-term diets of both brown trout and Bonneville cutthroat trout were similar between trout caught in beaver pond and lotic reaches. Finally, I found that growth rates of trout were also similar between the two habitats. In conclusion, the structure and function of macroinvertebrates, which are dependent on small-scale habitat features, were more affected by inclusion of beaver ponds to the stream network. Conversely, trout collected from beaver ponds and lotic regions were similar in growth and diet. Considering that beavers are used as a common restoration tool, further studies on the effects of beaver on stream communities is essential.

description: While our understanding of the issues surrounding foreign direct investment (FDI) in tourism is limited (Endo, 2006), even less is known about the role of FDI and other macroeconomic variables in the lodging segment of the tourism industry. This research fills this gap by examining the population of U.S. hotels with international operations with respect to FDI, Market Interconnectedness and Tourist Flows in foreign countries. Additional examination is performed separately on high-income and middle-income countries. Study findings suggest that Market Interconnectedness is highly significantly and positively correlated with presence of U.S. hotel firms abroad, while FDI and Tourist Flows are not. However, results somewhat differ with respect to high-income and middle-income countries.

description: We present [OIII 5007A] observations of the star forming galaxy HDF-BMZ1299 (z=1.598) using Keck Observatory's Adaptive Optics system with the near-infrared integral field spectrograph OSIRIS. Using previous Halpha and [NII] measurements of the same source, we are able for the first time to use spatially resolved observations to place a high-redshift galaxy's substructure on a traditional HII diagnostic diagram. We find that HDF-BMZ1299's spatially concentrated nebular ratios in the central ~1.5 kiloparsec (0."2) are best explained by the presence of an AGN: log([NII]/Halpha)=-0.22+/-0.05 and 2sigma limit of log([OIII]/Hbeta)>0.26. The dominant energy source of this galaxy is star formation, and integrating a single aperture across the galaxy yields nebular ratios that are composite spectra from both AGN and HII regions. The presence of an embedded AGN in HDF-BMZ1299 may suggest a potential contamination in a fraction of other high-redshift star forming galaxies, and we suggest that this may be a source of the "elevated" nebular ratios previously seen in seeing-limited metallicity studies. HDF-BMZ1299's estimated AGN luminosity is L_Halpha = 3.7e41 erg/s and L_[OIII] = 5.8e41 erg/s, making it one of the lowest luminosity AGN discovered at this early epoch.

description: We present a novel approach for nonlinear statistical shape modeling that is invariant under Euclidean motion and thus alignment-free. By analyzing metric distortion and curvature of shapes as elements of Lie groups in a consistent Riemannian setting, we construct a framework that reliably handles large deformations. Due to the explicit character of Lie group operations, our non-Euclidean method is very efficient allowing for fast and numerically robust processing. This facilitates Riemannian analysis of large shape populations accessible through longitudinal and multi-site imaging studies providing increased statistical power. Additionally, as planar configurations form a submanifold in shape space, our representation allows for effective estimation of quasi-isometric surfaces flattenings. We evaluate the performance of our model w.r.t. shape-based classification of hippocampus and femur malformations due to Alzheimer's disease and osteoarthritis, respectively. In particular, we outperform state-of-the-art classifiers based on geometric deep learning as well as statistical shape modeling especially in presence of sparse training data. We evaluate the performance of our model w.r.t. shape-based classification of pathological malformations of the human knee and show that it outperforms the standard Euclidean as well as a recent nonlinear approach especially in presence of sparse training data. To provide insight into the model's ability of capturing biological shape variability, we carry out an analysis of specificity and generalization ability.

title: Examining Teacher Perceptions When Utilizing Volunteers in School-Based Agricultural Education Programs
Creators: name: Cromer, Ashley B.
Publisher: name: Utah State University
Year: 2018

description: There has been little research conducted related to how school-based agricultural (SBAE) teachers perceive the utilization of volunteers in the classroom. The United States is facing a shortage of SBAE teachers, and with turnover rates that are not sustainable, solutions for support and reduction of the SBAE teachers’ workload must be sought with diligence. There is potential for volunteers to reduce some of the responsibilities that the SBAE teacher is faced with. The purposes of this study are to determine the demographic characteristics of the volunteers being utilized and of the SBAE teachers, determine the perceived benefits, barriers and beliefs SBAE teachers hold towards volunteer utilization, and determine if there is a relationship between these perceptions teachers hold and their choices in the utilization of volunteers. The research questions guiding this study were: 1. What are the demographic characteristics of SBAE teachers and programs in the United States? 2. What is the current utilization of volunteers in SBAE programs in the United States? 3. What are the perceptions and beliefs of SBAE teachers regarding volunteer utilization within SBAE programs in the United States? 4. What are the intentions of volunteer utilization among SBAE teachers in the United States? 5. What is the relationship between volunteer utilization and selected teacher/program characteristics and perceptions of SBAE teachers?
The total population of this study was all of the SBAE teachers in the United States. A simple random sample of this population was be taken (n=500), provided by the National FFA Association based on the 2017-2018 membership (N = 11,000). This descriptive study utilized survey research to accomplish the purpose, assessing the current utilization of volunteers, and the perceptions that SBAE teacher hold. Study participants were identified as SBAE teachers who held a part or full-time assignment to teach agriculture. Descriptive statistics were utilized to determine the demographic information of the volunteers utilized, the SBAE teachers, and program characteristics. These statistics were reported with frequencies, percentages, means, and standard deviations. Regression analysis was conducted to determine if any relationships existed between the program and teacher characteristics, and between the program and volunteer utilization.
A materials balance analysis : petroleum products in greater Vancouver
Creators: name: Dreher, Wilfried Hans
Publisher: name: University of British Columbia
Year: 2010

description: Identifying sources and pathways of pollutants is one of the most difficult problems to solve in the area of water quality management. The following three objectives focus on this problem in (1) developing the concept of the materials balance for identifying sources, pathways and sinks of petroleum products in an urban environment, (2) investigating the effects of pollution due to petroleum hydrocarbons in an urban area and (3) applying the planning technique of the materials balance in a case study of the Greater Vancouver Regional District. The state of the present understanding of the behaviour of oil in water, its toxicity to aquatic organisms and effects on the beneficial uses of water is reviewed and the essential literature on this subject is summarized. The materials balance technique, which is a complete accounting of all oil products entering into, flowing through and leaving an area, has been developed because it is recognized that present methods for identifying sources and pathways of pollution are unsystematic and therefore do not fully reveal the opportunities for controlling discharges of oily wastes. The principal conclusions of the study are the following: (1) Considerable uncertainty prevails in interpreting physiological and biological aspects of oil pollution. Available evidence indicates that the greatest hazards result from large spills and toxic substances contained in waste oils, predominantly heavy metals. (2) The materials balance has proven to be a useful planning technique for residuals management studies, in that it provides: a) a tool to identify size and sources of flows, thus identifying the critical waste streams; b) a framework for making "guesstimates", which are often unavoidable due to a lack of data and for testing the sensitivity of alternative assumptions; and c) a powerful model for analysing alternative policy mechanisms for pollution abatement and resource conservation. (3) Applying the materials balance to the Greater Vancouver Regional District, the following conclusions can be drawn: at present, oil pollution within the Greater Vancouver Regional District is not serious, however, there are problems that require further research such as the long term effects of oil pollution on the marine and estuarine environment and effects of pollution due to contaminated waste oils. It would seem preferable to understand and control the problem before oil pollution reaches serious levels due to future growth and industrialization.
title: The Heat Is On! Perspectives and Practices Regarding Extreme Heat Risk
Creators: name: Esplin, Emily D.
Publisher: name: Utah State University
Year: 2018

description: Remembering negative experiences with extreme heat may promote future protective actions and provide insight to improve heat risk awareness and communication practices. This two-part thesis found 1) that experiencing heat-related health symptoms predicted what Americans would do to protect themselves and others during subsequent heat waves; and 2) that Utah professionals regard heat-related experience as an important factor in how they responded to extreme heat events.
In the first study, a US national survey showed that personal experience with heat-related health symptoms was related to the tendency to say that one engaged in different protective behaviors, while other factors like risk perception and temperature were less related to self-reported behaviors. Sociodemographic factors such as age, race, and gender were related to Americans’ reported efforts to check on other people during a heat wave—with African-Americans, women, and older adults being more likely to do so— but did not have much relationship with how people personally protect themselves.
The second study found that heat experience was an important factor in how public officials and media broadcasters manage extreme heat situations. Interviews of professionals in Utah revealed that experience with heat impacts influenced public forecasters, practitioners, and media members alike in their heat risk decisions and messaging practices even though official heat risk communication products in Utah were somewhat unfamiliar. This study also found that public forecasters recently changed how they measure extreme heat to better communicate the dangers of dry heat in the Intermountain West. This change will likely cause more official heat alerts to be issued in this region.

In particular the emission line at 197.86 A is unblended and close to the peak of the EIS sensitivity curve, making it a valuable diagnostic of plasma at around 800,000 K - a critical temperature for studying the interface between the corona and transition region. Theoretical ratios amongst the four lines predicted from the CHIANTI database reveal weak sensitivity to density and temperature with observed values consistent with theory. The ratio of 197.86 relative to the 171.07 resonance line of Fe IX is found to be an excellent temperature diagnostic, independent of density, and the derived temperature in the analysed data set is log T=5.95, close to the predicted temperature of maximum ionization of Fe IX.

description: Object stores are widely used software stacks that achieve excellent scale-out with a well-defined interface and robust performance. However, their traditional get/put interface is unable to exploit data locality at its fullest, and limits reaching its peak performance. In particular, there is one way to improve data locality that has not yet achieved mainstream adoption: the active object store. Although there are some projects that have implemented the main idea of the active object store such as Swift's Storlets or Ceph Object Classes, the scope of these implementations is limited. We believe that there is a huge potential for active object stores in the current status quo. Hyper-converged nodes are bringing more computing capabilities to storage nodes --and viceversa. The proliferation of non-volatile memory (NVM) technology is blurring the line between system memory (fast and scarce) and block devices (slow and abundant). More and more applications need to manage a sheer amount of data (data analytics, Big Data, Machine Learning & AI, etc.), demanding bigger clusters and more complex computations. All these elements are potential game changers that need to be evaluated in the scope of active object stores. In this article we propose an active object store software stack and evaluate it on an NVM-populated node. We will show how this setup is able to reduce execution times from 10% up to more than 90% in a variety of representative application scenarios. Our discussion will focus on the active aspect of the system as well as on the implications of the memory configuration.

title: Investigating Rapid Concrete Repair Materials and Admixtures
Creators: name: Quezada, Ivan
Publisher: name: Utah State University
Year: 2018

description: This dissertation presents a literature review of the state-of-practice for the use of IC in concrete mixtures and how structural engineers and construction engineers can adapt IC to their present and future work. Current high early strength concrete mixtures have natural cracking and shrinkage problems due to the high content of cementitious material or their chemical components. Using IC allows for early strength, enhanced durability, reduced shrinkage and a better curing by providing water that can be absorbed by the cement past after the final set. Rapid hydration and high early strength Portland cement and calcium sulfoaluminate (CSA) concretes are commonly used as pavement repair media. The fresh properties (slump, setting time), mechanical properties (elastic modulus, compressive and tensile strength), and volume stability (autogenous shrinkage, drying shrinkage, restrained ring shrinkage, and creep) of rapid repair media were evaluated with and without internal curing with saturated lightweight aggregate. Significant improvements in volume stability were also noted. Results indicate that internal curing can successfully improve volume stability and mitigate restrained shrinkage cracking in rapid repair media without compromising fresh properties or ultimate mechanical strength. Maturity was observed for CSA mixtures and exhibited a correlation with compressive strength development which could be beneficial for rapid repair media on the field.

The two-dimensional internal rotation of KIC11145123

description: The two-dimensional internal rotation of KIC11145123 has been inferred via asteroseismology. Based on the Optimally Localized Averaging method and a simple three-zone modeling of the internal rotation, we have found evidence for a contrast between the internal rotation of the radiative region and that of the convective core; the radiative region rotates almost uniformly throughout the region, but the convective core may be rotating about 6 times faster than the radiative region above. We have also found a marginally significant evidence of latitudinal differential rotation in the outer envelope. These newly indicated features of the internal rotation of the star can help us further constrain the theory of angular momentum transport inside stars as well as understand the complex physical properties of the star, which was once thought to be a main-sequence A-type star but recently has been proposed to be a blue straggler, based on spectroscopy.

Determining the Muon Mass in an Instructional Laboratory

description: An instructional laboratory experiment to measure the muon mass is described. Using coincidence-anticoincidence detection, the decay of a cosmic-ray muon into an electron (or positron) is observed in a multiplate spark chamber, and recorded with a triggered CCD detector. The energy of the charged decay-product particle is then quantified by counting the number of spark gaps $n_S$ it traverses before being stopped by the chamber's aluminum plates. By running this apparatus under computer-control for several hours, the number of product-particles $N(n_S)$ with various $n_s$-values is obtained. The muon mass is obtained by a least-squares fit, which compares the experimentally observed $N(n_S)$ with simulation values predicted for this distribution by the Fermi description of muon decay via the weak interaction. We present the results for the muon mass we have obtained and discuss the simulation we developed to account for the observed skewing of $N(n_S)$ due to the various directions the spark-producing product particles move as well as the escape of some of the higher-energy particles from the chamber.

AbstractSurvival motor neuron 1 (SMN1), located on chromosome 5q, encodes the survival motor neuron (SMN) protein. A deletion or mutation in SMN1 results in a rare neuromuscular disorder: 5q spinal muscular atrophy (SMA). In such patients, SMN protein production relies solely on SMN2. Nusinersen (Spinraza®) is a modified antisense oligonucleotide approved for the treatment of 5q SMA. It modifies SMN2 pre-messenger RNA splicing, thereby increasing full-length SMN protein levels. Interim analyses from an ongoing phase II study suggest substantial clinical benefits with nusinersen (administered intrathecally) initiation in presymptomatic patients. In phase III studies, nusinersen achieved significant and/or clinically relevant improvements in motor function in symptomatic patients with infantile- and later-onset 5q SMA, and significantly improved event-free survival and overall survival in patients with infantile-onset 5q SMA. Longer term (up to ≈ 6 years), motor function was maintained or improved in symptomatic patients. Nusinersen had a favourable safety profile in clinical studies in presymptomatic and symptomatic patients. Real-world experience supports the effectiveness, safety and tolerability of nusinersen in symptomatic patients of all ages. Thus, nusinersen remains an important treatment option among a broad range of 5q SMA patients.
