description: We analyze the effects of adiabatic ramping of optical lattices on the temperature of spin-1 bosons in a homogeneous lattice. Using mean-field theory, we present the isentropes in the temperature-interaction strength ($T,U_0$) plane for ferromagnetic, antiferromagnetic, and zero spin couplings. Following the isentropic lines, temperature changes can be determined during adiabatic loading of current experiments. We show that the heating-cooling separatrix lies on the superfluid-Mott phase boundary with cooling occuring within the superfluid and heating in the Mott insulator, and quantify the effects of spin coupling on the heating rate. We find that the mean-field isentropes for low initial entropy terminate at the superfluid-Mott insulator phase boundary.

title: The Effects of a Novel Sport-Based Intervention on Lower Body Muscle Function in Older Adults
Creators: name: Dennis, Camille H.
Publisher: name: Utah State University
Year: 2019

description: Objective: This study aimed to examine the effects of a novel, small-court racquet sport, Pickleball, on lower body muscle power and functional performance of older adults, aged 60-75.
Background: Physical inactivity in the older adult population is associated with increased risks of falls, chronic illness, and decreased quality of life. Sports participation may have multiple benefits for improving these risks and have the added benefit of increased adherence among older adults. Pickleball, a popular new sport, is a small-court racquet sport that is moderate intensity, widely accessible, cost effective, and enjoyed by many older adults across the nation.
Methods: Five participants performed three isokinetic maximum voluntary contractions at 240°·s-1 for the knee extensor’s muscle group and three vertical jumps for measuring knee extensor power and lower body function, respectively, at baseline and after participating in 6 weeks of Pickleball play. Pickleball sessions were 1hour and occurred twice per week. Variables included mean knee extensor power and countermovement vertical jump height.
Results: The intervention resulted in moderate gains in knee extensor power (18.7% increases) and small gains in vertical jump height (7.5% increases). The effect sizes were 0.63 and 0.17 for the knee extensor power and jump height variables, respectively.
Conclusions: These findings offer some support showing that 6 weeks of Pickleball participation may elicit some modest gains, in a relatively short duration, for lower body function which could help older adults meet physical activity recommendations and help reduce the burdens of dysfunction on a long-term basis with a sport-based model that may offer advantages of sustainable physical activity. However, more work is needed to corroborate these findings with larger sample sizes and longer duration interventions.

description: Devices as Large Ring Laser Gyroscopes (RLG) for fundamental physics and geophysics investigation are currently run by means of RF power supply systems. This is not the standard method to supply a gas laser, that typically is powered with a DC system. In literature RF power supply lasers have been studied several years ago, and to correctly understand the behaviour of devices as RLG a more detailed study has been pursued. Detailed study of the radial distribution of the optical gain of an He-Ne discharge cell in function of gas pressure and RF power supply will be illustrated, discussed and compared with existing literature. The presented analysis demonstrates that it is possible to optimize the RLG operation with a proper choice of gas pressure and power level of the RF power supply. Accordingly we have been able to establish transversal and longitudinal single-mode operation our prototype GP2.

description: We revisit the three non-strange pentaquarks $[\frac 12\frac 12^-]_{S=0,1}$ and $[\frac 12\frac 32^-]_{S=1}$ predicted using the holographic dual description, where chiral and heavy quark symmetry are manifest in the triple limit of a large number of colors, large quark mass and strong $^\prime$t Hooft gauge coupling. In the heavy quark limit, the pentaquarks with internal heavy quark spin $S$ are all degenerate. The holographic pentaquarks are dual to an instanton bound to heavy mesons in bulk, without the shortcomings related to the nature of the interaction and the choice of the hard core inherent to the molecular constructions. We explicitly derive the spin-spin and spin-orbit couplings arising from next to leading order in the heavy quark mass, and lift totally the internal spin degeneray, in fair agreement with the newly reported charmed pentaquarks from LHCb. New charm and bottom pentaquark states are predicted.

description: Cosmic ray (CR) acceleration at the shock created by the expanding cocoons around active galactic nuclei (AGNs) is studied. It is shown that above the energy $10^{18}$ eV the overall energy spectrum of CRs, produced during the AGN evolution and released in the intergalactic space, has the form $N\propto ε^{-γ}$, with $γ\approx 2.6$, which extends up to $ε_{max}\sim 10^{20}$ eV. It is concluded that cocoons shocks have to be considered as a main source of extragalactic CRs, which together with Galactic supernova remnants provide the observed CR spectrum.

title: Friends or Foes? Composition and Creative Writing
Creators: name: Davis, Christopher N.
Publisher: name: Utah State University
Year: 2019

description: In the current realm of collegiate English, there exists a polarized separation between two fields: composition and creative writing. Though there are a number of ways these two fields intersect, they are seen and taught as distinct entities, and have been so for much of the last three decades. Some scholars see the blending of the two fields as potentially hindering to students’ writing development in either field – the idea that attempting to do two things at once, rather than focusing on each one at a time, will inevitably result in less-effectiveness in both. Others see creative writing as having no practical use, thus the need for the continued separation. Because of these stances, the closely-related fields function independently from one another; generally, neither actually considers the other in the classroom, despite the benefit(s) this could provide. However, while little has been written on what’s to be gained from integrating the two fields, much is lost due to the separation – e.g. the spark of interest in English, in general, that creative writing provides or the acute similarity in goals and skill-development that both fields share. In this paper, I examine the pedagogical benefits of integrating the two fields, focusing specifically on what’s to be gained by diminishing the separation. My materials will include scholarly articles from prominent journals in either field (such as College Composition and Communication, College English, and The Writer’s Chronicle, among others), as well as textbooks to provide specific details about the similarities between them. I aim to address questions concerning the current separation so modern scholars in each field will consider the immense benefit(s) of integrating aspects of each field in both the composition and creative writing classrooms.

description: We examine the spatial clustering of blue horizontal branch (BHB) stars from the $\textit{u}$-band of the Canada-France Imaging Survey (CFIS, a component of the Ultraviolet Near-Infrared Optical Northern Survey, or UNIONS). All major groupings of stars are associated with previously known satellites, and among these is NGC 5466, a distant (16 kpc) globular cluster. NGC 5466 reportedly possesses a long stellar stream, although no individual members of the stream have previously been identified. Using both BHBs and more numerous red giant branch stars cross-matched to $\textit{Gaia}$ Data Release 2, we identify extended tidal tails from NGC 5466 that are both spatially and kinematically coherent. Interestingly, we find that this stream does not follow the same path as the previous detection at large distances from the cluster. We trace the stream across 31$^{\circ}$ of sky and show that it exhibits a very strong distance gradient ranging from 10 $
title: Evaluation of Body Fat Prediction Equations from a Portable A-Mode Ultrasound (BodyMetrix) Compared to Bod Pod
Creators: name: Lowry, R. Stephan
Publisher: name: Utah State University
Year: 2019

description: A-mode ultrasound is a relatively inexpensive and noninvasive way of measuring subcutaneous fat thickness and estimating body fat percentage (%BF). The BodyMetrix BX2000 A-mode ultrasound is programmed with nine different equations that can be used to estimate %BF. The purpose of this study was to compare the %BF estimation from all nine equations available for adult males in this ultrasound system to the %BF estimation from Bod Pod air displacement plethysmography. Ultrasound measures were taken at 10 body sites on 42 males of varying age (28.6 ± 11.9 y), height (182.4 ± 7.6 cm), weight (84.5 ± 16.9 kg), and body mass index (24.5 ± 4.6 kg/m2). The %BF from the nine ultrasound formulas were compared to the estimate from the Bod Pod with a repeated-measures ANOVA. Three of the nine equations -- the Jackson and Pollock 3 site (JP3), Jackson and Pollock 7 site (JP7), and the NHCA 4 site -- had acceptable correlation coefficients (> 0.80), low mean differences that were not significant (p > 0.05), and insignificant bias. None of the equations had errors < 3.5%BF, but all three of these formulas had standard error of estimate (SEE) and total error (TE) of about 4%BF. Based on these findings, the JP3, JP7, and NHCA 4-site formulas in the BX2000 A-mode ultrasound are recommended over the other formula options for estimating the %BF of men.
Verso una soluzione neo-formalista al problema della definizione dellâ€™arte

Year: 2012

description: The problem of defining art has occupied analytical aesthetics for more than 50 years. A lot of solutions have been proposed, but none of them seems to be definitive. So, skepticism abounds, despite the great amount and variety of proposals. But less attention has been paid to recent attempts who seek the solution in linking art to traditional concepts such as aes-thetic experience, beauty, pleasure, and form, properly revised. In this paper I analyze this kind of attempts (such as that of Dutton, Beardsley, Eldridge, Shusterman, Scruton and, surprisingly enough, the latest Danto) trying to arrive to a unified aesthetic definition of art, which acknowledges the importance of content but states that form is what mostly matters, in being the instrument through which an artwork conveys its meaning and causes the spectator to have pleasurable aesthetic experiences. I also show how such condition ris-es and receives its force from the history of art in different cultures, there being universal basis for aesthetic appreciation of artworks. I conclude remarking some of the advantages of such a definition, allowing space for a subsequent discussion about possible objections and replies.

Subjects: migration, social media, rural-urban migration, integration, information dissemination.

description: The advent of social media has profoundly shaped contemporary migration patterns, particularly in facilitating rural-to-urban migration dynamics. Drawing on insights from Awumbila et al. (2017), Dekker et al. (2018), Alencar (2018), and Hidayati (2019), this study investigates the transformative role of social media in driving migration trends on a global scale. By providing migrants with access to abundant information and networking opportunities, social media platforms have emerged as pivotal tools influencing migration decision-making processes. The integration of social media into migration dynamics has not only facilitated the dissemination of information about destination conditions but also fostered connections and integration efforts among migrants. As highlighted by Dekker et al. (2018), social media minimizes migration costs and risks while enhancing migrants' access to relevant information, thus serving as a catalyst for migration flows. Moreover, Hidayati (2019) underscores the significance of social media networks in facilitating integration and connection opportunities for migrants, thereby fostering a sense of community and support both pre- and post-migration. By synthesizing insights from multiple studies, this research sheds light on the multifaceted impact of social media on migration dynamics, highlighting its potential to reshape spatial mobility patterns and influence settlement decisions.

The dynamic phase is intrinsic and linked to the Hamiltonian of a periodic linear Euler system on the co-algebra. The geometric phase is represented as a surface integral of the symplectic form of a co-adjoint orbit.

description: In this work, we develop the Tsallis entropy approach for examining the cross-shareholding network of companies traded on the Italian stock market. In such a network, the nodes represent the companies, and the links represent the ownership. Within this context, we introduce the out-degree of the nodes -- which represents the diversification -- and the in-degree of them -- capturing the integration. Diversification and integration allow a clear description of the industrial structure formed by the considered companies. The stochastic dependence of diversification and integration is modelled through copulas. We argue that copulas are well suited for modelling the joint distribution. The analysis of the stochastic dependence between integration and diversification by means of the Tsallis entropy gives a crucial information on the reaction of the market structure to the external shocks, - on the basis of some relevant cases of dependence between the considered variables. In this respect, the considered entropy framework provides insights on the relationship between in-degree and out-degree dependence structure and market polarisation or fairness. Moreover, the interpretation of the results in the light of the Tsallis entropy parameter gives relevant suggestions for policymakers who aim at shaping the industrial context for having high polarisation or fair joint distribution of diversification and integration. Furthermore, a discussion of possible parametrisations of the in-degree and out-degree marginal distribution, -- by means of power laws or exponential functions, -- is also carried out. An empirical experiment on a large dataset of Italian companies validates the theoretical framework.

description: The landscape of workflow systems for scientific applications is notoriously convoluted with hundreds of seemingly equivalent workflow systems, many isolated research claims, and a steep learning curve. To address some of these challenges and lay the groundwork for transforming workflows research and development, the WorkflowsRI and ExaWorks projects partnered to bring the international workflows community together. This paper reports on discussions and findings from two virtual "Workflows Community Summits" (January and April, 2021). The overarching goals of these workshops were to develop a view of the state of the art, identify crucial research challenges in the workflows community, articulate a vision for potential community efforts, and discuss technical approaches for realizing this vision. To this end, participants identified six broad themes: FAIR computational workflows; AI workflows; exascale challenges; APIs, interoperability, reuse, and standards; training and education; and building a workflows community. We summarize discussions and recommendations for each of these themes.

In particular, we have calculated the strange spin polarization Δs, the strangeness contribution to the weak axial vector couplings Δ_8 etc., strangeness contribution to the magnetic moments μ(p)^s etc., the strange quark flavor fraction f_s, the strangeness dependent quark flavor ratios \frac{2 \bar s}{u+d} and \frac{2 \bar s}{\bar u+ \bar d} etc.. Our results are consistent with the recent experimental observations.

Inferring stellar population properties with simulation-based inference in the LSST era.
Creators: name: Iglesias-Navarro, Patricia
Publisher: name: Zenodo
Year: 2024

description: Spectral energy distributions (SEDs) encode information about the stellar populations within galaxies. By investigating the properties of these stars, such as their ages, masses,  and metallicities, we can gain insights into the underlying physical processes that drive the growth and transformation of galaxies over cosmic time. For this purpose, we explore an amortized implicit inference approach to estimate the posterior distribution of stellar mass, star formation rate, metallicity and redshift of galaxies, using ACS and NIRCam filters. Fed with the MILES stellar population models, we generate a sample of synthetic SEDs to train and test our model. We show that our approach is capable of reliably estimating the properties of an integrated stellar population with, crucially, well-calibrated uncertainties. Once trained, deriving the posteriors is five orders of magnitude times faster than classical MCMC sampling, being able to address a large number of galaxies, and to perform a thick sampling of the posteriors, estimating the deterministic trends and the inherent uncertainty of this highly degenerated inversion problem. As a preliminary work, we apply this method to resolved galaxies from JWST, fitting every pixel to study gradients in the stellar populations properties, showing a good generalization to data. We believe that this machine-learning-based implicit inference framework applied to SED fitting is remarkably promising to deal with the size and complexity of the LSST survey.
An aperture synthesis radiotelescope and a deep sky survey at 22 MHz

description: A low-frequency radio astronomy telescope has been constructed at the Dominion Radio Astrophysical Observatory for operation at 22.25 MHz. It operates on the principle of aperture synthesis, and has been used to map a region of sky north of declination 70 degrees. The resolution and sensitivity of the telescope for discrete sources are 15 arc minutes and 2 Jansky respectively. The design of the telescope and some of the observations are described herein. The observations were taken during the sunspot minimum, mostly during the winter of 1976. The thesis includes a preliminary map with half the ultimate resolution (30 arc min.). Further data processing is planned. About 300 radio sources have been catalogued and low-frequency spectra defined. Some techniques for wide-field aperture synthesis are described.

title: The Impact of Master’s Level Education on the Assessment and Intervention of Pediatric Swallowing
Creators: name: Seagren, Andrea
Publisher: name: Utah State University
Year: 2019

description: Purpose: Pediatric swallowing disorders is increasing in prevalence as medical advancements are made. This increase raises the need for more speech-language pathologists (SLPs) to be involved in the assessment and intervention of pediatric swallowing. However, discrepancies exist in the amount and level of education being provided during academic coursework in the area of pediatric swallowing.
Method 1: The investigation had a two-tier approach. Part one included a survey specifically targeting SLPs who graduated within the most recent accreditation standards (2014 to present) and masters level students in their second year of graduate school (n=100). Part two explored academic courses offered by each (n=X) accredited American Speech-Language and Hearing Association (ASHA) graduate speech-language pathology program. Courses were categorized utilizing the nine major ASHA competency areas. Pediatric language and pediatric swallowing courses were pulled out and analyzed further.
Results: Only 6.6% of ASHA graduate programs currently require a pediatric feeding and swallowing course. On average, participants of the clinical experience survey felt slightly well prepared to assess and treat pediatric swallowing whereas they felt very well prepared to assess and treat pediatric language. This difference was significant at the level p < .05. The majority of respondents reported 0 hours of clinical experience in pediatric swallowing, and more hours of clinical experience was directly related to higher levels of perceived preparation to work in the area of pediatric swallowing disorders.
Conclusion: SLPs are uniquely qualified to provide pediatric feeding and swallowing therapy. The lack of education and clinical experience being provided within the graduate programs is creating a deficit in the high need for pediatric swallowing therapists and the low availability of them within the field. There are significant differences between the total number of pediatric language courses when compared to pediatric swallowing courses and that has the potential to impact the SLPs perceived level of preparation in the assessment and intervention of pediatric swallowing disorders. This points to the need for additional education and clinical experience for Master’s level graduate students in the area of pediatric swallowing.

description: Big Data are rapidly produced from various heterogeneous data sources. They are of different types (text, image, video or audio) and have different levels of reliability and completeness. One of the most interesting architectures that deal with the large amount of emerging data at high velocity is called the lambda architecture. In fact, it combines two different processing layers namely batch and speed layers, each providing specific views of data while ensuring robustness, fast and scalable data processing. However, most papers dealing with the lambda architecture are focusing one single type of data generally produced by a single data source. Besides, the layers of the architecture are implemented independently, or, at best, are combined to perform basic processing without assessing either the data reliability or completeness. Therefore, inspired by the lambda architecture, we propose in this paper a generic multimodal architecture that combines both batch and streaming processing in order to build a complete, global and accurate insight in near-real-time based on the knowledge extracted from multiple heterogeneous Big Data sources. Our architecture uses batch processing to analyze the data structures and contents, build the learning models and calculate the reliability index of the involved sources, while the streaming processing uses the built-in models of the batch layer to immediately process incoming data and rapidly provide results. We validate our architecture in the context of urban traffic management systems in order to detect congestions.
title: Stop-Signal Reaction Time Correlates with a Compensatory Balance Response in Older Adults
Creators: name: England, Derek
Publisher: name: Utah State University
Year: 2019

description: Response inhibition involves stopping undesired and automatic actions allowing for behavioral flexibility. This ability is theoretically able to contribute to fall prevention, which older adults are known to have difficulty with. Although much has been learned from cognitive psychology regarding response inhibition, translation to the challenge of balance recovery is unclear. Recently a correlation has been found between performance on a standard test of response inhibition called the Stop Signal Task (SST) and a balance test that required inhibition of a reactive step in young adults. This highlights a neural mechanism for stopping action across different behavioral contexts in young adults. The present study was conducted to determine if this relationship was similarly evident in older adults. A group of 19 older adults (50-85 years) performed the SST and reactive balance test separately. The SST evaluates an individual’s ability to suppress a visually-cued button press upon hearing a “Stop” tone, and measures the response inhibition speed called the Stop Signal Reaction Time (SSRT). Reactive balance was tested by releasing participants from a supported lean position, where the environment was changed during visual occlusion. Upon receiving vision, participants were required to step to regain balance, or suppress a step when obstacles were present. The stepping muscle responses between the “step” and “no step” trials were compared to quantify step suppression. Results indicated that SSRT was correlated with muscle activation in the stance leg. More specifically, individuals with faster SSRTs were also better at inhibiting leg muscle activation on no step trials. Present results suggest the ability to inhibit finger responses in a seated cognitive test reflects an individual’s capacity for response inhibition, which is preserved in a whole-body, balance recovery task. Potentially, response inhibition via the SST could identify a risk factor leading to falls and have clinical application.
Compressed sensing performance bounds under Poisson noise

description: This paper describes performance bounds for compressed sensing (CS) where the underlying sparse or compressible (sparsely approximable) signal is a vector of nonnegative intensities whose measurements are corrupted by Poisson noise. In this setting, standard CS techniques cannot be applied directly for several reasons. First, the usual signal-independent and/or bounded noise models do not apply to Poisson noise, which is non-additive and signal-dependent. Second, the CS matrices typically considered are not feasible in real optical systems because they do not adhere to important constraints, such as nonnegativity and photon flux preservation. Third, the typical $\ell_2$--$\ell_1$ minimization leads to overfitting in the high-intensity regions and oversmoothing in the low-intensity areas. In this paper, we describe how a feasible positivity- and flux-preserving sensing matrix can be constructed, and then analyze the performance of a CS reconstruction approach for Poisson data that minimizes an objective function consisting of a negative Poisson log likelihood term and a penalty term which measures signal sparsity. We show that, as the overall intensity of the underlying signal increases, an upper bound on the reconstruction error decays at an appropriate rate (depending on the compressibility of the signal), but that for a fixed signal intensity, the signal-dependent part of the error bound actually grows with the number of measurements or sensors. This surprising fact is both proved theoretically and justified based on physical intuition.

title: The Effects of Demographic Changes on State Fiscal Balances in the U.S.

Year: 2019

description: The share of the population that is 65 or older keeps on rising over the years in the U.S. According to the 2017 US population projection, the rate of growth of older population is much faster than other age groups. The growing aging population will affect the economy in many ways, especially in fiscal balance of regional governments. The main goal of the study is to examine the fiscal implication of increasing old-age population in U.S states. The old-age dependency ratio is used to measure aging population, which derived by diving the population 65 years and over by the 18 to 64 years population and multiplying by 100. The old-age dependency ratio increases government spending on primary education, public welfare (Medicaid), health and hospital, and highways and roads. The old-age dependency ratio increases property tax and corporate income tax while it has negative effects on individual income tax, other tax (taxes on motor vehicle licenses), charges (tolls on highway, tuition paid to state universities etc.), and all other revenue. All told, a one percent point increases in the old-age dependency ratio would decrease state fiscal balance by $104/person.

description: Due to the limited availability and high cost of the reverse transcription-polymerase chain reaction (RT-PCR) test, many studies have proposed machine learning techniques for detecting COVID-19 from medical imaging. The purpose of this study is to systematically review, assess, and synthesize research articles that have used different machine learning techniques to detect and diagnose COVID-19 from chest X-ray and CT scan images. A structured literature search was conducted in the relevant bibliographic databases to ensure that the survey solely centered on reproducible and high-quality research. We selected papers based on our inclusion criteria. In this survey, we reviewed $98$ articles that fulfilled our inclusion criteria. We have surveyed a complete pipeline of chest imaging analysis techniques related to COVID-19, including data collection, pre-processing, feature extraction, classification, and visualization. We have considered CT scans and X-rays as both are widely used to describe the latest developments in medical imaging to detect COVID-19. This survey provides researchers with valuable insights into different machine learning techniques and their performance in the detection and diagnosis of COVID-19 from chest imaging. At the end, the challenges and limitations in detecting COVID-19 using machine learning techniques and the future direction of research are discussed.

title: Reconstruction of Attenuated Hybrid Rocket Motor Chamber Pressure Signals Using Maximum Likelihood Estimation and Optimal Deconvolution
Creators: name: Zelesnik, Evan M.
Publisher: name: Utah State University
Year: 2019

description: Chamber pressure, as it develops during rocket combustion, strongly correlates with many of the internal motor ballistics, including combustion stability, fuel regression rate, and mass flow. Chamber pressure is also an essential measurement for calculating achieved thrust coefficient and characteristic velocity. Due to the combustion environment hostility, sensing chamber pressure with high-fidelity presents a difficult measurement problem, especially for solid and hybrid rocket systems where combustion by-products contain high amounts of carbon and other sooty materials. These contaminants tend to deposit within the pneumatic tubing used to transmit pressure oscillations from the thrust chamber to the sensing transducer. Partially clogged transmission tubes exhibit significant response latency and damp high frequency pressure oscillations that may be of interest to the testers. A maximum-likelihood method for fitting a second order model to chamber pressure response is presented. The resulting model was used to reconstruct a high-fidelity motor response via optimal deconvolution. The method was applied to small hybrid-thruster results from three separate testing campaigns. Key performance parameters such as thrust coefficient, characteristic velocity, and specific impulse were re-calculated using the reconstructed data. Results were compared to the unreconstructed data, and are shown to exhibit consistently better agreement with theoretical predictions.

description: A weakening of superconductivity upon substitution of Cu by Zn (0.5~1 %) is observed in a high-T_c cuprate, Ca_{2-x}Na_xCuO2Cl2, near the hole concentration of 1/8 per Cu. The superconducting transition temperature and its volume fraction, estimated by magnetic susceptibility, exhibit a sizable anomaly for x=0.12~0.14, where the slowing down of Cu spin fluctuations below 5 K is demonstrated by muon spin relaxation experiments. These observations are in close resemblance to other typical cuprates including YBa2Cu3O_{7-d}, and Bi2Sr2Ca_{1-x}Y_xCu2O_{8+d}, providing further evidence that Zn-induced "stripe" correlation is a universal feature of high-T_c cuprate superconductors common to that of La_{2-x}A_{x}CuO4 (A=Ba, Sr).

The ultrastructural evolution of early vertebrates

description: Conodonts, an extinct group of marine chordates, dominated the marine realm from the late Cambrian to Late Triassic. Their phosphatic teeth, known as elements, constituted their feeding apparatus. While elements are abundant, intact soft body remains are rare, with notable findings in the Carboniferous Granton Shrimp bed in Scotland. This discovery revealed key insights into conodont soft tissue anatomy, affirming a chordate affinity and potential link to stem gnathostomes. The scarcity of soft body remains hinders our understanding of conodonts' lifestyle. Studies rely on element facies composition to infer paleoenvironmental distributions, predominantly in shallow marine environments. Remarkably, conodonts pioneered mineralized tissues akin to vertebrate tooth enamel, distinguished by its unique growth and repair capabilities. This research focuses on conodont histology to address longstanding questions of early vertebrate evolution. Through Scanning Electron Microscopy and Synchrotron x-ray tomography, we aim to further unravel the mysteries surrounding conodonts, expanding our knowledge on their growth, ecology and relationships.

description: When a subnational input-output matrix is unavailable, a non-governmental organization (NGO) may turn to a shortcut method in order to project its indirect economic impact in a region. The location quotient is the most common choice in developed nations, but has serious theoretical flaws in a developing-nation context. We explore the minimum requirements method as a cost-effective yet robust method to project the impact of an NGO in the Imbabura province of Ecuador. We find that every $1 of exogenous local spending stimulates between $1.32 and $1.62 of indirect economic impact in the region.

description: The Canadian Ministry of Transport recommends that powerline crossings on river valleys be marked by white flashing lights. In remote areas a power supply for these lights can be difficult to obtain. A warning beacon system which uses the leakage current of semi-conductive glaze insulators to power a capacitive discharge flashtube is described. Consideration is given to the relevant characteristics of flash tubes and semiconductive glaze insulators. Tests which have been conducted to confirm the viability of the system are described.
N=4 Topological Amplitudes and Black Hole Entropy

description: We study the effects of N=4 topological string amplitudes on the entropy of black holes. We analyse the leading contribution associated to six-derivative terms and find one particular operator which can correct the entropy of N=4 black holes. This operator is BPS-like and appears in the effective action of type II string theory on K3 x T^2 or equivalently its heterotic dual on T^6. In both descriptions the leading contribution arises at one-loop, which we calculate explicitly on the heterotic side. We then consider whether this term has any consequences for the entropy of (large) N=4 black holes and find that it makes indeed a contribution at subleading order. Repeating the computation for small black holes with vanishing horizon area at the classical level, we prove that this coupling lifts certain flat directions in the entropy function thereby being responsible for the attractor equations of some moduli fields.
