description: We theoretically propose a second-order topological magnon insulator by stacking the van der Waals honeycomb ferromagnets with antiferromagnetic interlayer coupling. The system exhibits Z$_{2}$ topological phase, protected by pseudo-time-reversal symmetry (PTRS). An easy-plane anisotropy term breaks PTRS and destroys the topological phase. Nevertheless, it respects a magnetic two-fold rotational symmetry which protects a second-order topological phase with corner modes in bilayer and hinge modes along stacking direction. Moreover, an introduced staggered interlayer coupling establishes a Z$_{2}$$\times$Z topology, giving rise to gapped topological surface modes carrying non-zero Chern numbers. Consequently, chiral hinge modes propagate along the horizontal hinges in a cuboid geometry and are robust against disorders. Our work bridges the higher-order topology and magnons in van der Waals platforms, and could be used for constructing topological magnonic devices.

Nursing procedure for fetal heart rate auscultation during labor

Subjects: Fetal Heart Rate Monitoring
Maternity Nursing

description: For many years attempts have been made to define clinically the indicators of fetal distress during labor.  But the criteria for fetal distress have not been clearly defined and frequently paradoxical clinical situations have exited.  Increased comprehension of the intrauterine state of the fetus has been the object of much perinatal research.  Significant advances in fetal electrocardiography, biochemical studies and clinical assessment of the newborn have been made.  Certain changes in fetal heart rate have been observed in association with uterine contractions and have been correlated with biochemical and clinical evidence of fetal and neonatal distress.  Caldeyro-Barcia, one investigator of fetal heart rate changes during labor, identified two changes which indicate fetal distress; tachycardia, and a fall in rate which starts at or following the peak of the uterine contraction, reaches minimum values 30 to 50 seconds later, and recovers to initial values in about the same length of time as the fall.  This pattern he calls a Type II dip.  He states that these two indicators can be recognized by clinical auscultation it it is performed in a serial manner which he describes.  A modification of this suggested serial auscultation procedures was carried out during the labors of 15 women to test in a beginning way the feasibility of the clinical application of this medical research finding to nursing practice.  The results indicated the auscultation procedure to be feasible if care is taken to maintain mother and nurse comfort, distractions are kept to a minimum and time is allowed for the procedure.  Fetal heart rate patterns were identified and some recognized as resemble Type II dips.  In addition, relationships were demonstrated between the two indicators (tachycardia and fetal heart rate patterns resembling Type II dips) and Apgar rating one minute after birth.  The association of tachycardia and appearance of patterns resembling Type II dips with low Apgar rating of the newborn supports the findings of Caldeyro-Baarcia.

description: Using small-angle neutron scattering we have studied the vortex lattice in superconducting MgB$_2$ with the magnetic field applied along the $c$-axis, doped with either manganese or carbon to achieve a similar suppression of the critical temperature. For Mn-doping, the vortex lattice phase diagram remains qualitatively similar to that of pure MgB$_2$, undergoing a field-and temperature-driven $30^{\circ}$ rotation transition, indicating only a modest effect on the vortex-vortex interaction. In contrast, the vortex lattice rotation transition is completely suppressed in the C-doped case, likely due to a change in the electronic structure which affects the two-band/two-gap nature of superconductivity in MgB2. The vortex lattice longitudinal correlation length shows the opposite behavior, remaining roughly unchanged between pure and C-doped MgB$_2$ while it is significantly reduced in the Mn-doped case. However, the extensive vortex lattice metastability and related activated behavior, observed in conjunction with the vortex lattice transition in pure MgB$_2$, is also seen in the Mn doped sample. This shows that the vortex lattice disordering is not associated with a substantially increased vortex pinning.

The Design and Evaluation of a Simulation-Based Behavior Change Intervention for Individuals with Type 2 Diabetes
Creators: name: Gibson, Bryan Smith
Publisher: name: University of Utah
Year: 2014

description: This dissertation describes a line of research that addresses translational research questions related to the use of computerized simulation to affect the knowledge, beliefs, motivation and self-management behaviors of individuals with chronic disease. The specific research projects focus on type 2 diabetes (T2DM) and physical activity as exemplars of a prevalent chronic disease and an underutilized selfmanagement behavior, respectively. We first describe a conceptual framework for the design of Consumer Health Informatics (CHI) applications. The design of an envisioned diabetes self-management application is described as an example of the application of design principles derived from this framework. Subsequent chapters describe tests of research questions related to this envisioned intervention. The second chapter describes the development and preliminary evaluation of the interface for the intervention described above. The estimation of simulated glucose curves for individuals with T2DM is described. Next, the formative evaluation of a paperbased prototype based on those curves and a novel method to measure individuals' outcome expectations are described. The third chapter describes a randomized experiment of a narrated simulation based on simulated glucose curves. This trial tested the question: can computerized simulations affect the beliefs and behaviors of individuals with T2DM? In this experiment participants' beliefs changed in accordance with the discrepancy between the presented evidence, and their prior beliefs, and in combination with the completion of a planning intervention, which resulted in significantly greater increase in physical activity The fourth chapter describes a test of the question: can predictive models of the acute physiologic effects of behavior be individualized? In this study we compared different predictive modeling techniques and found that a mixed effects modeling approach improves in accuracy as the individual contributes more data. This result is foundational to the development of the next generation of our simulation-based intervention, and has implications for CHI as a field; these are discussed. The dissertation concludes with a review of the strengths and limitations of the work described, a discussion of the implications of this work for consumer health informatics and a brief discussion of the next steps in this line of research.

description: Classical Internet evolved exceptionally during the last five decades, from a network comprising a few static nodes in the early days to a leviathan interconnecting billions of devices. This has been possible by the separation of concern principle, for which the network functionalities are organized as a stack of layers, each providing some communication functionalities through specific network protocols. In this survey, we aim at highlighting the impossibility of adapting the classical Internet protocol stack to the Quantum Internet, due to the marvels of quantum mechanics. Indeed, the design of the Quantum Internet requires a major paradigm shift of the whole protocol stack for harnessing the peculiarities of quantum entanglement and quantum information. In this context, we first overview the relevant literature about Quantum Internet protocol stack. Then, stemming from this, we sheds the light on the open problems and required efforts toward the design of an effective and complete Quantum Internet protocol stack. To the best of authors' knowledge, a survey of this type is the first of its own. What emerges from this analysis is that the Quantum Internet, though still in its infancy, is a disruptive technology whose design requires an inter-disciplinary effort at the border between quantum physics, computer and telecommunications engineering.

Increasing ICU nurses' knowledge about post-anesthesia patient care
Creators: name: Burns, Kaitlin
Publisher: name: No Publisher Supplied
Year: 2020

description: PurposePatients are admitted from the operating room to the intensive care unit (ICU) for ICU nurses to recover patients from anesthesia. However, ICU nurses are not receiving the same training as post-anesthesia care nurses. To ensure the best outcomes, ICU nurses must receive education about caring for the post-operative patient. MethodologyThis project was a pre and post-test interventional design with one group of participants. An educational session about types of anesthesia, common complications from anesthesia, and guidelines about caring for the post-operative patient was presented to ICU nurses at a local hospital. A pre-test, post-test, and one month follow up test was completed by participants to see if knowledge changed as a result of the educational session. Data was analyzed using descriptive and analytical statistics. ResultsThe mean score of the pretest was 50, post-test was 86.6, and follow-up test was 80. A Friedman test yielded a statistically significant result indicating that the change in scores between the pretest, posttest, and follow up test were significant. The Wilcoxon test showed there was a significant change in test scores for the pretest compared to the posttest and the pretest compared to the follow up test. ImplicationsThis project is a stepping-stone for future research projects as there is currently minimal research about ICU nurses recovering patients from anesthesia. Additionally, this project provided education to ICU nurses about recovering patients from anesthesia, ongoing education can help to ensure competency and quality patient care. Finally, by having ICU nurses recover patients from anesthesia during off hours, the hospital can reduce the amount of money spent on on-call pay for PACU nurses

description: This study was a survey of community health nursing resources and requirements in Utah by health district. The research technique utilized was derived from a model designed by the Western Interstate Commission on Higher Education. The model looks at current and projected needs for community health nurses. It compares demands with current and projected supplies of nurses by educational level in 12 local health districts. The primary finding of the study indicates that the projected supply of educationally-prepared nurses will be inadequate to meet requirements in the majority of health districts.

description: Flexible, goal-directed behavior is a fundamental aspect of human life. Based on the free energy minimization principle, the theory of active inference formalizes the generation of such behavior from a computational neuroscience perspective. Based on the theory, we introduce an output-probabilistic, temporally predictive, modular artificial neural network architecture, which processes sensorimotor information, infers behavior-relevant aspects of its world, and invokes highly flexible, goal-directed behavior. We show that our architecture, which is trained end-to-end to minimize an approximation of free energy, develops latent states that can be interpreted as affordance maps. That is, the emerging latent states signal which actions lead to which effects dependent on the local context. In combination with active inference, we show that flexible, goal-directed behavior can be invoked, incorporating the emerging affordance maps. As a result, our simulated agent flexibly steers through continuous spaces, avoids collisions with obstacles, and prefers pathways that lead to the goal with high certainty. Additionally, we show that the learned agent is highly suitable for zero-shot generalization across environments: After training the agent in a handful of fixed environments with obstacles and other terrains affecting its behavior, it performs similarly well in procedurally generated environments containing different amounts of obstacles and terrains of various sizes at different locations.

description: Demographic factors influence the intensity and duration of conflicts and collective violence is more common where there are high numbers of young men to older  men, and where there are more marriageable men to women. The notion that young, unmarried men are more likely than other cohorts to be unattached risk-takers explains these findings. This dissertation investigates whether these same demographic factors increase the likelihood a country will produce suicide attackers.  Information on individual attackers was assembled from three earlier studies and corroborated using LexisNexis searches of major world news publications. Personal  information, including age, sex, and country of origin, was collected for 1,208 individual suicide attackers who acted between 1981 and 2007. This information was then used to create a second dataset to make comparisons between countries and regions that produced suicide attackers and those that did not. Thirty-three of the 219 countries and regions analyzed produced suicide attackers, and those that did had higher numbers of  marriageable men to women, higher polygyny rates, higher percentages of Muslims in their populations, and larger populations overall. Counter to the hypothesis, countries with higher numbers of young men to old were less likely to produce suicide attackers. It may be that the older men in polygynous societies create an even greater scarcity of marriageable women, making it more difficult for young men to marry. Faced with relatively few reproductive and perhaps other alternatives, these young men are more prone to become suicide attackers.

description: Based on sociological, economic, and social-psychological theories of discrimination and bias, this study addresses non-native accents among ethnic minority students as they begin school and explores effects of such accents on their teachers’ achievement expectations. Using a unique data set of first graders in Germany, the analysis reveals that a non-native accent is relevant to teachers’ expectations net of student skills, abilities, and other background variables. Associations are stronger in the language domain than in mathematics, indicating that teachers perceive accent-free speech as a language-learning requirement. However, residual influences of non-native accents on teacher expectations also exist in the math domain and persist even after prolonged periods of teacher-student interaction. Mechanisms of statistical discrimination and stereotype-based discrimination can partially explain these effects. However, the overall pattern of results suggests a stigmatization of non-native accents, potentially resulting from the activation of negative associations related to foreignness and disfluency.

description: The cells of the mammalian immune system exhibit special migratory properties within their in vivo environment, a characteristic that is thought to be important in the protection of the organism by a process known as immunological surveillance. The present study utilized a radiotracer technique to establish that ultraviolet radiation (UVR), an environmental carcinogen, can induce alterations in the physiology of the immune apparatus, as reflected by the migration of lymphoid cells within mice exposed to UVR. The impact of the recirculation of lymphocytes on adoptive immunity was addressed by characterizing and utilizing inhibitors of in vivo cellular migration. Pertussis toxin, a protein secreted by the bacterium Bordetella pertussis, was shown to induce a selective and long-lasting inhibitition of the emigration of lymphocytes from the bloodstream into solid tissue. This blockade was associated with an inhibition of certain cell-mediated immune responses in vivo. The inhibitory effect was established to be a direct result of the toxin-mediated defect in cellular migration. The molecular mechanism of the inhibition was investigated in vitro, using as a model the well-defined system of chemotaxis of polymorphonuclear neutrophils. The characteristics of inhibition which were observed in this in vitro assay system were quite similar to those observed in vivo. Further, the mechanism of inhibition was demonstrated to be associated with a defect in the regulation of the intracellular channeling of free calcium, a postulated second messenger in the biochemical process of cellular stimulus-response coupling.  The results of the present studies support the conclusion that the recirculation of lymphocytes plays a major role in the in vivo function of the immune system, and thus homeostasis of the host organism. Further, these studies provide a basis for further experimentation to define the molecular processes which control cellular migration in vivo.

description: A new type of finite volume WENO schemes for hyperbolic problems was devised in [36] by introducing the order-preserving (OP) criterion. In this continuing work, we extend the OP criterion to the WENO-Z-type schemes. We firstly rewrite the formulas of the Z-type weights in a uniform form from a mapping perspective inspired by extensive numerical observations. Accrodingly, we build the concept of the locally order-preserving (LOP) mapping which is an extension of the order-preserving (OP) mapping and the resultant improved WENO-Z-type schemes are denoted as LOP-GMWENO-X. There are four major advantages of the LOP-GMWENO-X schemes superior to the existing WENO-Z-type schemes. Firstly, the new schemes can amend the serious drawback of the existing WENO-Z-type schemes that most of them suffer from either producing severe spurious oscillations or failing to obtain high resolutions in long calculations of hyperbolic problems with discontinuities. Secondly, they can maintain considerably high resolutions on solving problems with high-order critical points at long output times. Thirdly, they can obtain evidently higher resolution in the region with high-frequency but smooth waves. Finally, they can significantly decrease the post-shock oscillations for simulations of some 2D problems with strong shock waves. Extensive benchmark examples are conducted to illustrate these advantages.

Identification and characterization of the gene causing paroxysmal nonkinesigenic dyskinesia

description: Paroxysmal nonkinesigenic dyskinesia (PNKD) is an autosomal-dominant disorder that belongs to a group of hyperkinetic movement disorders called the paroxysmal dyskinesias. PNKD is characterized by spontaneous paroxysmal attacks of any combination of dystonia, chorea, athetosis, and ballism, which are precipitated by alcohol, coffee, stress, and fatigue. Previous reports indicated that the PNKD locus was located on chromosome 2q, but the gene responsible for PNKD was not known. This dissertation describes the search and ultimate discovery of the gene responsible for PNKD. We performed PNKD locus fine-mapping, built a physical contig across the PNKD locus, and analyzed of disease haplotypes through PNKD kindreds in order to facilitate the screening process for the PNKD gene. Direct sequencing and denaturing high pressure liquid chromatography (dHPLC) were used for screening genes located within the PNKD region. We identified two missense mutations in a novel gene called Myofibrillogenesis Regulator 1 (MR-1), which caused PNKD in 50 affected individuals from eight PNKD kindreds. The mutations caused alanine-tovaline changes in the N-terminus of two MR-1 isoforms. The MR-1L isoform is specifically expressed in neurons and is localized to the cell membrane, while the MR-1S isoform is ubiquitously expressed and shows diffuse cytoplasmic and nuclear localization. The mRNA of the MR-1 mouse ortholog, brain protein 17 (BRP17), shows a wide expression pattern throughout the mouse central nervous system (CNS). The expression of MR-1/BRP17 in the cerebral cortex, cerebellum, spinal cord, and basal ganglia, implied that MR-1 plays an important role in maintaining the excitability of these essential parts of the motor system. Bioinformatic analysis reveals that the MR-1 gene is homologous to the hydroxyacylglutathione hydrolase (HAGH) gene. HAGH functions in a pathway to detoxify methylglyoxal, a compound present in coffee and alcoholic beverages and produced as a by-product of oxidative stress. Our results suggest a mechanism whereby alcohol, coffee, and stress may act as precipitants of attacks in PNKD. Since MR-1, unlike the genes known of cause other episodic disorders, is neither an ion channel nor an ion exchanger gene, it provides a new avenue for exploration into the pathophysiology of episodic phenomena like PNKD and perhaps epilepsy or migraine.

description: While recent gravitational wave observations by LIGO and Virgo allow for tests of general relativity in the extreme gravity regime, these observations are still blind to a large swath of phenomena outside these instruments' sensitivity curves. Future gravitational-wave detectors, such as LISA, will enable probes of longer-duration and lower-frequency events. In particular, LISA will enable the characterization of the non-linear dynamics of extreme mass-ratio inspirals, when a small compact object falls into a supermassive black hole. In this paper, we study the motion of test particles around spinning black holes in two quadratic gravity theories: scalar Gauss-Bonnet and dynamical Chern-Simons gravity. We show that geodesic trajectories around rotating black holes in these theories are likely to not have a fourth constant of the motion. In particular, we show that Poincaré sections of the orbital phase space present chaotic features that will affect the inspiral of small compact objects into supermassive black holes in these theories. Nevertheless, the characteristic size of these chaotic features is tiny and their location in parameter space is very close to the event horizon of the supermassive black hole. Therefore, the detection of such chaotic features with LISA is likely very challenging, at best.

MOSFET

description: With the scaling of MOSFET dimensions and the performance enhancement features in the MOSFET, semiconductor manufacturing variation has also increased. Because of process variation and other reliability issues, circuits tend to move away from the nominal operating point, therefore degrading the parametric yield of the circuits. To assess the impact of process variations on the parametric yield of integrated circuits, an accurate process variation detection scheme is needed. This dissertation presents a new process variation detection and compensation technique. This technique uses the difference of the rise and fall slew as another metric along with delay in order to determine the magnitude and the relative mismatch between the drive strengths of the NMOS and PMOS devices. The importance of considering both of these metrics is illustrated, and a new slew-rate monitoring circuit is presented for use in measuring the difference of rise and fall slew on the critical path of the circuit. The measurement sensitivity of fabricated slew-rate monitor in a 65nm IBM CMOS technology is 0.11 V/?s with 1089 pF as the output load of the slew-rate monitor.

Detection of diethyl ether in human blood.

Subjects: Blood Collection

description: Research was conducted to develop a valid analytical method for determining levels of diethyl ether in blood below the 1 part per million (ppm) levels (volume/volume).  Two gas chromatographic methods, the head space and the purge and the purge and trap, were adapted to meet the needs of low-level analysis in blood.  These 2 methods were then evaluated and compared for limit of detection, for sensitivity, and for suitability in routine use in monitoring exposure levels of diethyl ether.  Studies were also made to determine if vacutainer blood collection tubes could be utilized as blood collection and storage containers.  Field verification tests were conducted to evaluate the utility of the blood collection system and the analytical method.  Electroencephalogram technicians from local hospitals were used as exposed volunteers.  Environmental air and blood samples were obtained, evaluated, and compared.  The data indicated that the vacutainer blood collection system could be used as long as the blood samples were stored at 5° for less than 1 week.  The 2 analytical methods were both found to be capable of measuring diethyl ether in blood at parts-per-billion (ppb) levels.  The purge-and-trap method was found to be more sensitive and to have the lower detection limit.  The head-space method was somewhat easier to use and did not require the use of complex purge-and trap glassware and equipment.  However, the utility of the head-space method was not considered significant enough to offset its lower sensitivity, its higher limit of detection, and its higher levels of variability in results.  The results of this study demonstrate that low levels of diethyl ether can be detected in human blood using available technology and that further development and evaluation studies could result in a practical and useful biological monitoring test method for low levels of diethyl ether and other volatile organic substances in blood.

description: Multi-parameter estimation is necessary for force sensing due to simultaneous and nontrivial small changes of position and momentum. Designing quantum probes that allow simultaneous estimation of all parameters is therefore an important task. The optimal methods for estimation of the conjugate changes of position and momentum of quantum harmonic oscillator employ probes in entangled or quantum non-Gaussian states. We show that the same results can be obtained in a significantly more feasible fashion by employing independent sets of differently squeezed Gaussian states classically correlated to position or momentum measurements. This result demonstrates an unexplored power of a classical correlation between the probe states and measurements directly applicable to force sensing

description: Game theoretic models of marketing channels typically rely on simplifying assumptions that, from a behavioral perspective, often appear naïve. However, behavioral researchers have produced such an abundance of behavioral regularities that they are impossible to incorporate into game theoretic models. We believe that a focus on three core findings would benefit both fields; these are: first, beliefs that are held by the various players regarding profit consequences of different actions are incomplete and often biased; second, players’ preferences and optimization objectives are not commonly known; and third, players have insufficient cognitive abilities to achieve optimization objectives. Embracing these three findings shifts the focus from rational decision making to how decision makers learn to improve their decision-making skills. Concluding, we believe that greater convergence of game theoretic modeling and behavioral research in marketing channels would lead to new insights for both fields.
Von Neumann's information engine without the spectral theorem

description: Von Neumann obtained the formula for the entropy of a quantum state by assuming the validity of the second law of thermodynamics in a thought experiment involving semipermeable membranes and an ideal gas of quantum-labeled particles. Despite being operational in the most part, von Neumann's argument crucially departs from an operational narrative in its use of the spectral theorem. In this work we show that the role of the spectral theorem in von Neumann's argument can be taken over by the operational assumptions of repeatability and reversibility, and using these we are able to explore the consequences of the second law also in theories that do not possess a unique spectral decomposition. As a byproduct, we obtain the Groenewold--Ozawa information gain as a natural monotone for a suitable ordering of instruments, providing it with an operational interpretation valid in quantum theory and beyond.
