description: A fish farm is an area where fish raise and bred for food. Fish farm environments support the care and management of seafood within a controlled environment. Over the past few decades, there has been a remarkable increase in the calorie intake of protein attributed to seafood. Along with this, there are significant opportunities within the fish farming industry for economic development. Determining the fish diseases, monitoring the aquatic organisms, and examining the imbalance in the water element are some key factors that require precise observation to determine the accuracy of the acquired data. Similarly, due to the rapid expansion of aquaculture, new technologies are constantly being implemented in this sector to enhance efficiency. However, the existing approaches have often failed to provide an efficient method of farming fish. This work has kept aside the traditional approaches and opened up new dimensions to perform accurate analysis by adopting a distributed ledger technology. Our work analyses the current state-of-the-art of fish farming and proposes a fish farm ecosystem that relies on a private-by-design architecture based on the Hyperledger Fabric private-permissioned distributed ledger technology. The proposed method puts forward accurate and secure storage of the retrieved data from multiple sensors across the ecosystem so that the adhering entities can exercise their decision based on the acquired data. This study demonstrates a proof-of-concept to signify the efficiency and usability of the future fish farm.

description: Managing a child with acute lymphoblastic leukemia (ALL) after relapse is arduous in low- and middle-income countries. A file review of children aged ≤15 years diagnosed with relapsed ALL from 2010 to 2019 was performed. Classification of relapse followed the Berlin-Frankfurt-Münster (BFM) scheme. The majority of patients were treated with a modified ALL-REZ-BFM protocol. Of 764 children treated for ALL in the study period, 163 (21.3%) relapsed. The median age at relapse was 101 months (range: 8–297). The immunophenotype was B-ALL and T-ALL in 140 (86%) and 23 (14%) patients. The site of relapse was extramedullary, combined, and medullary in 46 (28%), 45 (28%), and 72 (44%) patients. Very early, early, and late relapses were observed in 57 (35%), 66 (40%), and 40 (25%) patients. The proportions of extramedullary and medullary sites were greater among patients with early and late relapses, respectively (p = 0.039). Eighty-four (52%) patients were treated with palliative intent. The 2-year event-free survival (EFS) of patients treated with curative intent was 36.3 ± 6.3%. The 2-year EFS for very early/early and late relapses were 18.2 ± 6.2% and 67.6 ± 10.4% (p < 0.001). The 2-year EFS did not differ between extramedullary, combined, and medullary relapses. Treatment-related mortality occurred in 14 (20%) patients. More than 50% of the patients with relapse were treated with the intent of palliation. Extramedullary relapses were more likely to be early and did not have a better outcome than medullary relapses. Children with late relapse had a fair chance of survival with chemotherapy.

description: Some Cataclysmic Variables (CVs) exhibits a very long photometric period (VLPP). We calculate the properties of a hypothetical third body, initially assumed on circular--planar orbit, by matching the modelled VLPP to the observed one of four CVs studied here: {\sl LU Camelopardalis} (LU Cam), QZ Serpentis (QZ Ser), V1007 Herculis (V1007 Her) and BK Lyncis (BK Lyn). The eccentric and low inclination orbits for a third body are considered using analytical results. The chosen parameters of the binary components are based on the orbital period of each CV. The smallest corresponding semi-major axis permitted before the third body's orbit becomes unstable is also calculated. A first-order analytical post-Newtonian correction is applied, and the rate of precession of the pericentre is found, but it can not explain any of the observed VLPP. For the first time, we also estimate the effect of secular perturbations by this hypothetical third body on the mass transfer rate of such CVs. We made sure that the observed and calculated amplitude of variability was comparable too. The mass of the third body satisfying all constrains range from 0.63 to 97 Jupiter masses. Our results show further evidence supporting the hypothesis of a third body in three of these CVs, but only marginally in V1007 Her.

IMPACT OF PRIOR AEROBIC EXERCISE ON ARTERIAL STIFFNESS DURING PROLONGED SITTING IN HEALTHY, ACTIVE MALES AND FEMALES
Creators: name: Riley, Sasha
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Prolonged sitting is associated with arterial stiffening, however acute aerobic exercise can transiently decrease arterial stiffness. To examine the impact of aerobic exercise on brachial-femoral (bfPWV) and femoral-ankle pulse wave velocity (faPWV) during prolonged sitting, measurements were taken at baseline, after exercise but before sitting (pre), and post-sitting (post). Thirteen participants (22 [3] y, 40% F) performed 30-minutes of walking at moderate-intensity (EX) or 30-minutes of standing (STAND) followed by 2.5-hours of uninterrupted sitting. No effects were present for bfPWV (p = 0.667). A condition x time interaction was present for faPWV (p < 0.001). From baseline to pre, EX decreased by 6.5% while STAND increased by 6.1%, leading to a difference between conditions. However, during sitting, faPWV rebounded in EX by 14.1% that resulted in no difference between conditions at post. Therefore, prior aerobic exercise does not appear to attenuate increases in arterial stiffness caused by prolonged sitting.

description: The elimination of alkyl halides is one of the most common and most direct strategies for       accessing terminal olefins. However, most common elimination methods require the use of harsh       reagents, which limits the functional group compatibility of the reaction. We have developed a mild      cobaltate-catalyzed elimination of alkyl chlorides, using a readily available pre-catalyst and a       zinc/ammonium chloride system as a mild reductant. The reaction is suitable for substrates with a variety       of functionality, including esters, benzyl ethers, carbamates, and free alcohols. The reported system also       eliminates primary, secondary, and tertiary chlorides efficiently. The reaction demonstrates the strong       nucleophilicity of anionic Co(I) cobaloximes, as well as the efficacy of cobaloximes as simple model       complexes for vitamin-B12.

description: Exciton condensation, a Bose-Einstein condensation of excitons into a single quantum state, has recently been achieved in low-dimensional materials including twin layers of graphene and van der Waals heterostructures. Here we examine computationally the beginnings of exciton condensation in a double layer comprised of coronene, a seven-benzene-ring patch of graphene. As a function of interlayer separation, we compute the exciton population in a single coherent quantum state, showing that the population peaks around 1.8 at distances near 2 Å. Visualization reveals interlayer excitons at the separation distance of the condensate. We determine the exciton population as a function of the twist angle between the two coronene layers to reveal the magic angles at which the condensation peaks. As with previous recent calculations showing some exciton condensation in hexacene double layers and benzene stacks, the present two-electron reduced-density-matrix calculations with coronene provide computational evidence for the ability to realize exciton condensation in molecular-scale analogs of extended systems like the graphene double layer.

description: Fermion-exciton condensates (FECs) -- computationally and theoretically predicted states that simultaneously exhibit the character of superconducting states and exciton condensates -- are novel quantum states whose properties may involve a hybridization of superconductivity and the dissipationless flow of energy. Here, we exploit prior investigations of superconducting states and exciton condensates on quantum devices to identify a tuneable quantum state preparation entangling the wave functions of the individual condensate states. Utilizing this state preparation, we prepare a variety of FEC states on quantum computers -- realizing strongly correlated FEC states on current, noisy intermediate-scale quantum devices -- and verify the presence of the dual condensate via postmeasurement analysis. This confirmation of the previously predicted condensate state on quantum devices as well as the form of its wave function motivates further theoretical and experimental exploration of the properties, applications, and stability of FECs.

description: Using data from the 2020 Cooperative Election Study, I investigate the relationship between feelings of racial resentment and approval of climate policy and explore how that relationship varies by type of agreement. I seek to extend an emerging literature that has demonstrated a link between racial attitudes and approval for climate policy by exploring how feelings of racial resentment shape public support for international climate cooperation. I find support for the linkage between heightened levels of racial resentment and reduced support for climate policy among those who identify as Republicans, Democrats, and independents. Additionally, for Republicans and independents, I find that the effect of racial resentment at reducing support for climate action is stronger when the climate action in question is U.S. involvement in an international agreement. My findings provide insight into the conditions that influence support for both domestic and international climate policy among members of the American public.

description: Detailed observations of gaps in protoplanetary disks have revealed structures that drive current research on circumstellar disks. One such feature is the two intensity nulls seen along the outer disk of the HD 142527 system, which are particularly well traced in polarized differential imaging. Here we propose that these are shadows cast by the inner disk. The inner and outer disk are thick, in terms of the unit-opacity surface in H-band, so that the shape and orientation of the shadows inform on the three-dimmensional structure of the system. Radiative transfer predictions on a parametric disk model allow us to conclude that the relative inclination between the inner and outer disks is 70+-5 deg. This finding taps the potential of high-contrast imaging of circumstellar disks, and bears consequences on the gas dynamics of gapped disks, as well as on the physical conditions in the shadowed regions.

description: OBJECTIVE:
To determine whether parenthood predicts host resistance to the common cold among healthy volunteers experimentally exposed to a common cold virus.
METHODS:
Participants were 795 healthy volunteers (age range = 18-55 years) enrolled in one of three viral-challenge studies conducted from 1993 to 2004. After reporting parenthood status, participants were quarantined, administered nasal drops containing one of four common cold viruses, and monitored for the development of a clinical cold (infection in the presence of objective signs of illness) on the day before and for 5 to 6 days after exposure. All analyses included controls for immunity to the experimental virus (prechallenge specific antibody titers), viral strain, season, age, sex, race/ethnicity, marital status, body mass, study, employment status, and education.
RESULTS:
Parents were less likely to develop colds than nonparents were (odds ratio [OR] = 0.48, 95% confidence interval [CI] = 0.31-0.73). This was true for both parents with one to two children (OR = 0.52, 95% CI = 0.33-0.83) and three or more children (OR = 0.39, 95% CI = 0.22-0.70). Parenthood was associated with a decreased risk of colds for both those with at least one child living at home (OR = 0.46, 95% CI = 0.24-0.87) and those whose children all lived away from home (OR = 0.27, 95% CI = 0.12-0.60). The relationship between parenthood and colds was not observed in parents aged 18 to 24 years but was pronounced among older parents.
CONCLUSIONS:
Parenthood was associated with greater host resistance to common cold viruses.

description: Aquilegia x miniana (J.F.Macbr. & Payson) Cronk, hybr. & stat. nov. is the correct name for the hybrid Aquilegia flavescens S.Watson x A. formosa Fisch. ex DC. var. formosa. In 1916, Payson and Macbride, while exploring the mountains of Idaho, found populations of Aquilegia that were pink in flower colour and appeared intermediate between the yellow-flowered A. flavescens and red-flowered A. formosa. They named these plants A. flavescens var. miniana J.F.Macbr. & Payson. There has been uncertainty over whether their type collections (in GH, RM, MO, US, E, CM, CAS, NY) do indeed represent hybrids or pink-flowered morphs of A. flavescens. Using a Wells diagram, the holotype (in the Gray Herbarium of Harvard University) is shown to be intermediate, allowing its identification as a clear hybrid. However, some of the isotype material is indistinguishable from A. flavescens. The holotype matches material from British Columbia that has been determined as being of hybrid origin using molecular and morphological data. A. flavescens var. miniana J.F.Macbr. & Payson is, therefore, an available name for the hybrid, which is here raised to the status of hybrid binomial.

title: Spoken language multilingualism in deaf children
Creators: name: Wright, Emily Sarah
Publisher: name: University of Reading
Year: 2023

description: An increasing number of D/deaf children are born to multilingual parents who must decide whether to raise them with spoken language multilingualism (SLM). This PhD comprises three studies designed around the evidence-based practice framework to support professionals in their role in helping multilingual parents make informed communication decisions. Study 1 investigates the beliefs of 108 professionals on SLM in deaf children and what advice they give to parents. Study 2 explores the decision-making process around SLM in deaf children from the parents’ perspective through 14 semi-structured interviews. Study 3 examines the language and cognitive abilities of five deaf children with SLM compared to five oral monolingual deaf children, five hearing monolingual children and five hearing multilingual children. Results from study 1 found that most professionals believed deaf children can achieve SLM and would advise parents to speak their home language. However, in study 2, whilst parents greatly valued professional advice, they reported receiving mixed advice on SLM. They also had a strong desire to speak their home language to provide better language models and support the child’s cultural identity and family relationships. Study 3 suggests that deaf children can achieve SLM. Although expressive vocabulary skills in English were lowest for the deaf children with SLM, three out of five scored above average compared to monolingual test norms. Morphosyntactic abilities in English and parental self-rating of abilities in the home language, were also comparable to the multilingual hearing children. Finally, deaf children with SLM had similar executive function and Theory of Mind abilities to the other three groups. The decision-making process around SLM is complex for multilingual parents of deaf children and professionals play a key role. The three studies will help professionals engage in evidence-based practice when supporting multilingual parents of deaf children to make informed decisions regarding SLM.

description: To predict liquid-gas two-phase flow phenomena, accurate tracking and prediction of the evolving liquid-gas interface is required. Volume-of-Fluid or VoF method has been used in the literature for computationally modeling of such flows. In the VoF method, a single set of governing equations are solved for both phases along with an advection equation for the volume fraction. The properties in each computational cell are determined by a linear weighted average of the properties of the two fluids based on the phase fraction. While the method predicts water-air flows well, the predictions tend to deviate significantly from experimental data for liquids with high viscosity. A new property averaging technique is proposed in this paper, which is shown to provide accurate results for high viscosity liquids. Computational predictions using the open source VoF solver interFoam (available as a part of the OpenFOAM computational tool), and those obtained using the proposed method are compared with experimental data for multiple two-phase applications. Four different problems, viz., suspended droplet in air, jet breakup, drop impact on thin films, and air entrapment during drop interaction with liquid pool, are considered to extensively validate the new method. Experimental data are used to cover a range of surface tension and viscosities. For all cases, the modified VoF solver is observed to perform significantly better than original VoF method.

description: In this thesis, we present three image processing tools inspired by and designed for histology image analysis. Histology, which is the examination of biological tissue under a microscope, is a critical technique in biomedical research and clinical practice. While slide preparation and imaging is increasingly becoming automated, the analysis of the resulting histology images is not: even routine analyses still require the trained eyes of a pathologist. In our work, we aim to understand histology images as a class of signals and develop tools to aid in the automated analysis of these signals. Our first contribution is in the area of histology image normalization, where the goal is to digitally remove the variation in staining between histology images, an important preprocessing step in many histology image analysis systems. To this end, we created a new benchmark dataset with which to compare normalization methods and proposed our own. Our second contribution is a tissue segmentation method, which delineates single-tissue regions in histology images. Along with this method, we propose a new mathematical model for histology images. Our final contribution is a method for describing distributions of angles, which is useful for segmentation as well as a variety of other image processing tasks.

description: We present a study of the prevalence and luminosity of Active Galactic Nuclei (AGN; traced by optical spectra) as a function of both environment and galaxy interactions. For this study we used a sample of more than 250000 galaxies drawn from the Sloan Digital Sky Survey and, crucially, we controlled for the effect of both stellar mass and central star formation activity. Once these two factors are taken into account, the effect of the local density of galaxies and of one-on-one interactions is minimal in both the prevalence of AGN activity and AGN luminosity. This suggests that the level of nuclear activity depends primarily on the availability of cold gas in the nuclear regions of galaxies and that secular processes can drive the AGN activity in the majority of cases. Large scale environment and galaxy interactions only affect AGN activity in an indirect manner, by influencing the central gas supply.

description: Underwater Vehicles have become more sophisticated, driven by the off-shore sector and the scientific community's rapid advancements in underwater operations. Notably, many underwater tasks, including the assessment of subsea infrastructure, are performed with the assistance of Autonomous Underwater Vehicles (AUVs). There have been recent breakthroughs in Artificial Intelligence (AI) and, notably, Deep Learning (DL) models and applications, which have widespread usage in a variety of fields, including aerial unmanned vehicles, autonomous car navigation, and other applications. However, they are not as prevalent in underwater applications due to the difficulty of obtaining underwater datasets for a specific application. In this sense, the current study utilises recent advancements in the area of DL to construct a bespoke dataset generated from photographs of items captured in a laboratory environment. Generative Adversarial Networks (GANs) were utilised to translate the laboratory object dataset into the underwater domain by combining the collected images with photographs containing the underwater environment. The findings demonstrated the feasibility of creating such a dataset, since the resulting images closely resembled the real underwater environment when compared with real-world underwater ship hull images. Therefore, the artificial datasets of the underwater environment can overcome the difficulties arising from the limited access to real-world underwater images and are used to enhance underwater operations through underwater object image classification and detection.

description: The constant center frequency to bandwidth ratio (Q-factor) of wavelet transforms provides a very natural representation for audio data. However, invertible wavelet transforms have either required non-uniform decimation -- leading to irregular data structures that are cumbersome to work with -- or require excessively high oversampling with unacceptable computational overhead. Here, we present a novel decimation strategy for wavelet transforms that leads to stable representations with oversampling rates close to one and uniform decimation. Specifically, we show that finite implementations of the resulting representation are energy-preserving in the sense of frame theory. The obtained wavelet coefficients can be stored in a timefrequency matrix with a natural interpretation of columns as time frames and rows as frequency channels. This matrix structure immediately grants access to a large number of algorithms that are successfully used in time-frequency audio processing, but could not previously be used jointly with wavelet transforms. We demonstrate the application of our method in processing based on nonnegative matrix factorization, in onset detection, and in phaseless reconstruction.

description: This comparison aims to present different functionalities provided by two software tools among the most used for production availability analyses: MAROS (developed by DNV) and GRIF/BStok (developed by Total). The different functionalities are presented and compared through tables. Then, a case study allows comparing the results obtained by the two tools. MAROS and GRIF/BStok both provide production availability analyses that meet industrial needs. While the use of MAROS brings to the user more "conviviality", a drawback is the "black box" aspect that results from it. BStok, thanks to the underlying exploitation of Petri nets, supplies more modeling flexibility in exchange of higher expertise.

description: In the absence of data from a randomized trial, researchers may aim to use observational data to draw causal inference about the effect of a treatment on a time-to-event outcome. In this context, interest often focuses on the treatment-specific survival curves, that is, the survival curves were the population under study to be assigned to receive the treatment or not. Under certain conditions, including that all confounders of the treatment-outcome relationship are observed, the treatment-specific survival curve can be identified with a covariate-adjusted survival curve. In this article, we propose a novel cross-fitted doubly-robust estimator that incorporates data-adaptive (e.g., machine learning) estimators of the conditional survival functions. We establish conditions on the nuisance estimators under which our estimator is consistent and asymptotically linear, both pointwise and uniformly in time. We also propose a novel ensemble learner for combining multiple candidate estimators of the conditional survival estimators. Notably, our methods and results accommodate events occurring in discrete or continuous time, or an arbitrary mix of the two. We investigate the practical performance of our methods using numerical studies and an application to the effect of a surgical treatment to prevent metastases of parotid carcinoma on mortality.

description: Objective: To present the first 3D CGO-based absolute EIT reconstructions from experimental tank data. Approach: CGO-based methods for absolute EIT imaging are compared to traditional TV regularized non-linear least squares reconstruction methods. Additional robustness testing is performed by considering incorrect model\textbf{}ing of domain shape. Main Results: The CGO-based methods are fast, and show strong robustness to incorrect domain modeling comparable to classic difference EIT imaging and fewer boundary artefacts than the TV regularized non-linear least squares reference reconstructions. Significance: This work is the first to demonstrate fully 3D CGO-based absolute EIT reconstruction on experimental data and also compares to TV-regularized absolute reconstruction. The speed (1-5 seconds) and quality of the reconstructions is encouraging for future work in absolute EIT.

description: Location tracking on mobile devices like smartphones has already begun to revolutionize personal navigation. Unfortunately, these services perform poorly indoors when GPS signals are no longer available. Highly accurate indoor location tracking would enhance a wide variety of applications including: building navigation (malls, factories, airports), augmented reality, location-aware pervasive computing, targeted advertising, social networking, participatory sensing and could even support next generation beam forming MIMO wireless networks. Current indoor localization systems for smartphones often use RF signal strength from WiFi access points or Bluetooth Low Energy (BLE) beacons to fingerprint indoor locations. Such systems are sensitive to environmental changes and obstructions, require extensive training procedures and are limited in both absolute as well as semantic localization accuracy. We propose using audio signals in the ultrasound spectrum, just above the human hearing range, to provide ranging and localization for many off-the-shelf mobile devices that are equipped with microphones. Ultrasonic ranging provides several advantages over RF-based ranging and fingerprinting approaches, which make it attractive for indoor localization. A relatively low propagation speed and carrier frequency allow for precise propagation time measurements in software using commodity hardware. Acoustic signals also have a low penetration depth, which confines them to target areas for accurate semantic localization. In this dissertation we address several challenges related to acoustic localization, including system scalability, ranging and localization accuracy, energy efficiency, robustness to noise, elimination of human perceivable audio artifacts, efficient use of limited acoustic bandwidth and rapid deployment strategies.
The Reliability of Vascular and Hemodynamic Measures Across the Oral Contraceptive Cycle

description: The oral contraceptive (OC) cycle is often controlled for in physiological studies by measuring OC users solely in the inactive phase. While this practice seeks to reduce potential measurement variability due to the impact of hormonal fluctuation on physiological function, it also impairs our understanding of women’s physiology, conceals sex differences, and decreases generalizability. Since this variability is not consistently demonstrated across the current literature, there is a need for further investigation into whether controlling for the cycle is necessary, by assessing physiological measurement reliability in OC users. This study therefore investigated the reliability of vascular and hemodynamic measures across the OC cycle in young, healthy women.      Our study found acceptable reliability for all vascular and hemodynamic outcomes across the OC cycle. Therefore, it may not be necessary to control for the cycle, as these measures of interest appear equally representative of cardiovascular function in each cycle phase.

Understanding and Recreating Visual Appearance Under Natural Illumination

description: The appearance of an outdoor scene is determined to a great extent by the prevailing illumination conditions. However, most practical computer vision applications treat illumination more as a nuisance rather than a source of signal. In this dissertation, we suggest that we should instead embrace illumination, even in the challenging, uncontrolled world of consumer photographs.
Our first main contribution is an understanding of natural illumination from images. This is, in general, a hard problem given the wide appearance variation in scenes. Fortunately, natural illumination, while complex, is far from being completely arbitrary. It has a structure that is well understood in atmospheric optics, but which has hardly been exploited in vision and graphics. We introduce methods for automatically estimating the illumination conditions from two types of uncontrolled outdoor image datasets: webcams and single images. The variation in sun position and sky appearance over time can be exploited to obtain viewing and illumination geometry in webcam sequences. For single images, the sky is combined in a probabilistic way with other scene features such as cast shadows and shading on vertical surfaces and convex objects, as well as with illumination priors from large image collections.
Our second main contribution is to exploit the knowledge of illumination in order to synthesize novel, realistic visual content. Instead of creating appearance using the traditional computer graphics pipeline, we propose to borrow the appearance of the world that is contained in existing photo collections and webcam datasets. We also demonstrate realistic 3-D object insertion by creating plausible high-dynamic range environment maps. This can be done in image sequences, and even in single images, completely automatically. Addressing such questions has implications in a broad range of applications including intelligent transportation, surveillance, human-robot interaction, and digital entertainment.
