description: Objective:To assess the performance of an adapted American Diabetes Association (ADA) risk score and the concise Finnish Diabetes Risk Score (FINRISC) for predicting type 2 diabetes development in women with and at risk of HIV infection.Design:Longitudinal analysis of the Women's Interagency HIV Study.Methods:The women's Interagency HIV Study is an ongoing prospective cohort study of women with and at risk for HIV infection. Women without prevalent diabetes and 3-year data on fasting blood glucose, hemoglobin A1c, self-reported diabetes medication use, and self-reported diabetes were included. ADA and FINRISC scores were computed at baseline and their ability to predict diabetes development within 3 years was assessed [sensitivity, specificity and area under the receiver operating characteristics (AUROC) curve].Results:A total of 1111 HIV-positive (median age 41, 60% African American) and 454 HIV-negative women (median age 38, 63% African-American) were included. ADA sensitivity did not differ between HIV-positive (77%) and HIV-negative women (81%), while specificity was better in HIV-negative women (42 vs. 49%, P = 0.006). Overall ADA discrimination was suboptimal in both HIV-positive [AUROC = 0.64 (95% CI: 0.58, 0.70)] and HIV-negative women [AUROC = 0.67 (95% CI: 0.57, 0.77)]. FINRISC sensitivity and specificity did not differ between HIV-positive (72 and 49%, respectively) and HIV-negative women (86 and 52%, respectively). Overall FINRISC discrimination was suboptimal in HIV-positive [AUROC = 0.68 (95% CI: 0.62, 0.75)] and HIV-negative women [AUROC = 0.78 (95% CI: 0.66, 0.90)].Conclusion:Model performance was suboptimal in women with and at risk of HIV, while greater misclassification was generally observed among HIV-positive women. HIV-specific risk factors known to contribute to diabetes risk should be explored in these models.

description: Motivation has generally been concentrated as an individual marvel with little research exploring how motivational attributes could impact the learner's academic performance. The study assessed the relationship between motivational attributes and academic performance of freshman college students in a state university in Cebu, Philippines. Specifically it sought to answer the following queries: The profiles of the respondents in terms of age and gender, the students’ grade point average, and to find out if there is a correlation between motivational attributes and academic performance for a six month period (one semester). The descriptive method was utilized in the study using quantitative analysis of data gathered. It employed simple percentage, weighted mean, chi-square, co-efficient of contingency, and t-test to come up with data interpretation. The results of the chi-square test showed rejection of the null hypothesis. The computed t-value was also greater than the tabled value of 1.96 at 0.05 level of significance. The research study indicated that relationship exists between motivational attributes and academic performance among the identified respondents.

description: We report an unexpected reverse spiral turn in the final stage of the motion of rolling rings. It is well known that spinning disks rotate in the same direction of their initial spin until they stop. While a spinning ring starts its motion with a kinematics similar to disks, i.e. moving along a cycloidal path prograde with the direction of its rigid body rotation, the mean trajectory of its center of mass later develops an inflection point so that the ring makes a spiral turn and revolves in a retrograde direction around a new center. Using high speed imaging and numerical simulations of models featuring a rolling rigid body, we show that the hollow geometry of a ring tunes the rotational air drag resistance so that the frictional force at the contact point with the ground changes its direction at the inflection point and puts the ring on a retrograde spiral trajectory. Our findings have potential applications in designing topologically new surface-effect flying objects capable of performing complex reorientation and translational maneuvers.

REACTIVE OXYGEN SPECIES ON INDOOR SURFACES
Creators: name: Yao, Zhenduo
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Reactive Oxygen Species (ROS) are relatively unstable oxygen-containing radicals or non-radicals, some of which may react with tissues and biomolecules after entering the human body. ROS is present in indoor aerosols, but it is unclear how much is of indoor origin. As a potentially important source of ROS generation, indoor surfaces are now known to be coated with unsaturated hydrocarbons that can react with ozone and other oxidants. In this study, the ROS concentration on several indoor surfaces was measured using a xylenol orange ferrous oxidation assay after wiping and extraction. The preliminary results show that, on surfaces frequently touched by occupants, the concentration is about 0.2 nmol/cm2; this is two to three times greater than on surfaces not frequently touched. In addition, kitchen surfaces exposed to cooking fumes contain even higher concentrations of peroxide, with some exceeding 0.5 nmol/cm2. Based on this observation, we studied the development of ROS in laboratory experiments. To simulate the oxidation of unsaturated hydrocarbons on indoor surfaces, artificial skin lipids (ASL) were dosed on 19 identical glass plates which were exposed to untreated laboratory air for 56 days. The solvent evaporates almost immediately leaving a thin oil film with an average thickness of about 3 nm that covers about 80 cm2. Ozone was measured continuously during the exposure and averaged 37 ppb. The ROS concentrations in the ASL film were measured daily for 2 weeks, then weekly after that. During the first 5-6 days, the ROS concentration increased roughly linearly to a maximum of 6-7 nmol/cm2. Then it starts fluctuating in the following week, perhaps reflecting a dynamic balance between the formation and decay. And after 2 weeks it decreases slowly, indicating some ROS partitions to air and/or decays. These field and laboratory results support the hypothesis that indoor surfaces can be a source of ROS; more research needs to be done to determine if the surfaces contribute significantly to ROS present on indoor PM.

Remarks: Monatractides oza closely resembles M. oxystomus (K. Viets, 1935), a species known from Indonesia and Thailand (Pešić & Smit 2009b) from which it differs in having slightly shorter and wider frontal platelets, but this character is known to be variable. A further difference is found in the absence of denticles at the distal margins of P-2 and P-3 (see Cook, 1967: Fig. 244). The variability needs to be examined to clarify the taxonomy (Pešić & Smit 2009b).

description: Background:The association between HIV and asthma prevalence and manifestations remains unclear, with few studies including women.Setting:A retrospective observational cohort study from the Multicenter AIDS Cohort Study and Women's Interagency HIV Study.Methods:Asthma was defined in 2 ways: (1) self-report and (2) robust criteria requiring all the following: lack of fixed airflow obstruction, presence of wheeze on the St. George's Respiratory Questionnaire (SGRQ), and report of asthma therapies. Estimates of asthma prevalence and asthma-related manifestations were compared by HIV serostatus.Results:A total of 1815 men and 2122 women were included. Asthma prevalence did not differ between people with HIV (PWH) and people without HIV regardless of definition: self-report (men, 12.0% vs. 11.2%; women, 24.3% vs. 27.5%) and robust criteria (men, 5.0% vs. 3.4%; women, 12.8% vs. 13.2%). Among men with asthma, worse respiratory symptom burden was reported among those with HIV, regardless of asthma definition. Among women with self-reported asthma, those with HIV had less respiratory symptom burden. Regardless of serostatus, women with robust-defined asthma had similar respiratory symptoms across SGRQ domains and similar frequencies of phlegm, shortness of breath, and wheezing.Conclusions:Among PWH and people without HIV, asthma prevalence was 2-fold to 3-fold higher using self-reported definition rather than robust definition. In men and women, HIV was not associated with increased asthma prevalence. In men, HIV was associated with more respiratory symptoms when asthma was self-reported; the relationship was attenuated with the robust criteria. Further studies are needed to explore asthma phenotypes among PWH.

"The Scorpion-Man: Posthumanism in Buñuel's l'âge d'or"
Creators: name: Cook, Simon
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: This paper takes as its starting point the overlooked inclusion of André Bayard’s little-known nature documentary Le scorpion languedocien (1912) at the beginning of Luis Buñuel’s iconic surrealist film L’âge d’or (1930). I argue that the inclusion of scenes from Bayard’s documentary throws into sharp relief a distinctly surrealist interest in posthumanism. Following Breton’s first manifesto, I study surrealists Suzanne Césaire’s and Roger Caillois’s theories about nature-culture and human-nonhuman hybridity and argue that L’âge d’or presents the “pure psychic automatism” of hybridity. To this end, I focus on the historical and cultural significance of the scorpion as a combined symbol of duality and hybridity. I further consider the human-nonhuman binary by reading it through the ethology-anthropology binary (Caillois), demonstrating that Buñuel’s film breaks both by articulating a human-scorpion hybridity at the levels of narrative and form. I therefore consider scenes from the film that reflect a deconstruction of the anthropological notion of “Man.” By way of conclusion, I refer to Rosi Braidotti and explain how L’âge d’or—and surrealism, writ large—could be read as a posthumanism avant la lettre in its desire to move beyond the humanism organized according to the nature-culture and human-nonhuman binaries.
A New Standard for the Analysis and Design of Replication Studies
Creators: name: Held, Leonhard
Publisher: name: arXiv
Year: 2018
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: A new standard is proposed for the evidential assessment of replication studies. The approach combines a specific reverse-Bayes technique with prior-predictive tail probabilities to define replication success. The method gives rise to a quantitative measure for replication success, called the sceptical p-value. The sceptical p-value integrates traditional significance of both the original and replication study with a comparison of the respective effect sizes. It incorporates the uncertainty of both the original and replication effect estimates and reduces to the ordinary p-value of the replication study if the uncertainty of the original effect estimate is ignored. The proposed framework can also be used to determine the power or the required replication sample size to achieve replication success. Numerical calculations highlight the difficulty to achieve replication success if the evidence from the original study is only suggestive. An application to data from the Open Science Collaboration project on the replicability of psychological science illustrates the proposed methodology.

description: Spin foam theory is a concrete framework for quantum gravity where numerical calculations of transition amplitudes are possible. Recently, the field became very active, but the entry barrier is steep, mainly because of its unusual language and notions scattered around the literature. This paper is a pedagogical guide to spin foam transition amplitude calculations. We show how to write an EPRL-FK transition amplitude, from the definition of the 2-complex to its numerical implementation using \texttt{sl2cfoam-next}. We guide the reader using an explicit example balancing mathematical rigor with a practical approach. We discuss the advantages and disadvantages of this approach and provide a novel look at a recently proposed approximation scheme.

description: The study aimed to ascertain the Rivers State University undergraduates’ awareness and response to below-the-line media campaigns on drug abuse. Specifically, the study sought to determine the level of exposure of Rivers State University students to below-the-line media campaign against drug abuse; find out if Rivers State University students adhere to below-the-line media campaigns on drug abuse among others. The research design adopted for this study was descriptive survey design. The population of this study consisted of the students of Rivers State University in Rivers State. The population of the institutions was obtained from the office of the Registrar of each of the institutions. The total population for the study was 24,325. In determining the sample size for this study, Taro Yamane mathematical formula was adopted. The sample size for the study was 400 and the study adopted the multi-stage sampling technique. Data for this study were obtained using copies of questionnaire. The research questions were analysed using the contingency tables were used to present data obtained from the questionnaire using weighted mean score. Findings from the study revealed that, all the respondents accepted to have heard, seen or read about drugs abuse in the campus. The result still revealed that the majority of the respondents had heard, seen or read about the drug to a low intensity among others. Based on the findings of this study, the researcher concludes that: media precipitates widespread awareness and as such served as a veritable medium for social mobilization. Below-the-line media such as billboard, signboard, posters, fliers, T-shirt, caps, handbills, etc demonstrated less competence in creating drug abuse exposure. The study, therefore, recommended that media, especially, on the below-the-line media should through their day-to-day reportage focus surveillance on the many ills and menace in the society so as to use them as themes for campaign. Also, campaigns should be designed such that they will have rudiments of the issues that form the subject matter of such campaigns. In this way, many people will see the need to key into the highlights of the message themes.

The Lorentzian proper vertex amplitude: Classical analysis and quantum derivation

description: Spin foam models, an approach to defining the dynamics of loop quantum gravity, make use of the Plebanski formulation of gravity, in which gravity is recovered from a topological field theory via certain constraints called simplicity constraints. However, the simplicity constraints in their usual form select more than just one gravitational sector as well as a degenerate sector. This was shown, in previous work, to be the reason for the "extra" terms appearing in the semiclassical limit of the Euclidean EPRL amplitude. In this previous work, a way to eliminate the extra sectors, and hence terms, was developed, leading to the what was called the Euclidean proper vertex amplitude. In the present work, these results are extended to the Lorentzian signature, establishing what is called the Lorentzian proper vertex amplitude. This extension is non-trivial and involves a number of new elements since, for Lorentzian bivectors, the split into self-dual and anti-self-dual parts, on which the Euclidean derivation was based, is no longer available. In fact, the classical parts of the present derivation provide not only an extension to the Lorentzian case, but also, with minor modifications, provide a new, more four dimensionally covariant derivation for the Euclidean case. The new elements in the quantum part of the derivation are due to the different structure of unitary representations of the Lorentz group.

description: This paper proposes a novel multimodal self-supervised architecture for energy-efficient audio-visual (AV) speech enhancement that integrates Graph Neural Networks with canonical correlation analysis (CCA-GNN). The proposed approach lays its foundations on a state-of-the-art CCA-GNN that learns representative embeddings by maximizing the correlation between pairs of augmented views of the same input while decorrelating disconnected features. The key idea of the conventional CCA-GNN involves discarding augmentation-variant information and preserving augmentation-invariant information while preventing capturing of redundant information. Our proposed AV CCA-GNN model deals with multimodal representation learning context. Specifically, our model improves contextual AV speech processing by maximizing canonical correlation from augmented views of the same channel and canonical correlation from audio and visual embeddings. In addition, it proposes a positional node encoding that considers a prior-frame sequence distance instead of a feature-space representation when computing the node's nearest neighbors, introducing temporal information in the embeddings through the neighborhood's connectivity. Experiments conducted on the benchmark ChiME3 dataset show that our proposed prior frame-based AV CCA-GNN ensures better feature learning in the temporal context, leading to more energy-efficient speech reconstruction than state-of-the-art CCA-GNN and multilayer perceptron.

description: In this work we study an alternative topological model for explaining the observed acceleration of space-time, we answer the question of whether this acceleration could be a consequence of the topology of the universe. For doing that, we propose that the whole universe is composed of a four dimensional base space, which represents space-time, endowed with a fiber forming a principal fiber bundle. We analyze this hypothesis for a homogeneous and isotropic four dimensional space-time and show that the effect of the fiber onto the base space is that the space-time accelerates depending on the group of the fiber, even in an oscillatory way, resembling the behavior of the universe according to recent observations. We conclude that there is the possibility of the accelerating behavior of the universe being due to its whole topology instead of an exotic kind of matter.

description: Abstract

Background: PRC stored blood products undergo changes in morphology, biochemistry, and metabolic called storage lesion red blood cells (erythrocytes storage lesion). Morphological changes of erythrocyte membrane phospholipids and damage due to oxidative damage and hemolysis allegedly produce microparticles known as erythrocyte-derived microparticles (EMP) and F2α-isoprostanes. F2α-isoprostanes are the indicators used to assess lipid peroxidation and cellular oxidative stress. Increased EMP-isoprostanes F2α in the PRC product allegedly one of the cause’s bad outcomes in transfusions. Aim: to know the correlation between red blood cells storage lesions (F2α-isoprostane) with erythrocyte-derived microparticles (CD235a) in the PRC product based storage time day 0, 7,14,21 and 28 at blood banks Hospital Dr. M. Djamil Padang. Methods: The cross-sectional study of 14 PRC units came from 14 heallthy donors at Blood Bank of Dr. M.Djamil Padang Hospital. The study lasted from the month of May 2016 to August 2017. The tests were conducted during 28 days of storage at 1-week intervals. Examination the level F2α-isoprostane with methods Enzyme-linked immunosorbant assay (ELISA) and examination of EMP levels (CD235a) with flowcytometry method. Bivariate statistical analysis of the correlation parameter storage lesion red blood cells (F2α-isoprostanes) with EMP (CD235a) using Pearson correlation test with a P value <0.05 indicates exhibited significantly. Results: Fourteen units of PRC obtained the largest donors were male (85.7%) with the highest blood type is O (42.9%). During storage there is an increased the amount of F2α-isoprostane and erythrocyte-derived microparticles (EMP) in the PRC product. There was no statistically significant correlation between the level F2α-isoprostane F2α and the amount of EMP in the during storage up to 28 days. Conclusion: There was no statistically significant correlation between the level-isoprostane F2α and the amount of EMP in the storage PRC.

Recent work has started to approach this problem through the lens of quantum computing, which promises theoretical speed-ups for several traditionally hard tasks. In this work, we examine a class of hybrid quantum-classical RL algorithms that we collectively refer to as variational quantum deep Q-networks (VQ-DQN). We show that VQ-DQN approaches are subject to instabilities that cause the learned policy to diverge, study the extent to which this afflicts reproduciblity of established results based on classical simulation, and perform systematic experiments to identify potential explanations for the observed instabilities. Additionally, and in contrast to most existing work on quantum reinforcement learning, we execute RL algorithms on an actual quantum processing unit (an IBM Quantum Device) and investigate differences in behaviour between simulated and physical quantum systems that suffer from implementation deficiencies. Our experiments show that, contrary to opposite claims in the literature, it cannot be conclusively decided if known quantum approaches, even if simulated without physical imperfections, can provide an advantage as compared to classical approaches. Finally, we provide a robust, universal and well-tested implementation of VQ-DQN as a reproducible testbed for future experiments.

description: BACKGROUND AND OBJECTIVES: Coronavirus disease 2019 (COVID-19) created a "perfect storm" for financial fraud targeting older adults. Guided by the Contextual Theory of Elder Abuse, we focused on individual and systemic contexts to examine how older adults became prey to financial fraud. RESEARCH DESIGN AND METHODS: In July 2020, 998 adults who were 60-98 years of age (93% White; 64% female) completed an online survey about experiences with financial fraud. Participants were recruited from gerontology research registries at Florida State University, University of Pittsburg, Virginia Tech, and Wayne State University. RESULTS: Over half (65.9%) of the respondents experienced a COVID-19-related scam attempt, with charity contributions (49%) and COVID-19 treatments (42%) being the most common. Perpetrators commonly contacted older adults electronically (47%) two or more times (64%). Although most respondents ignored the request (i.e., hung up the phone and deleted text/e-mail), 11.3% sent a requested payment, and 5.3% provided personal information. Predictors of vulnerability included contentment with financial situation, concern about finances in the aftermath of the pandemic, and wishing to talk to someone about financial decisions. Respondents targeted for a non-COVID-19 scam attempt were less likely to be targets of a COVID-19-related scam. DISCUSSION AND IMPLICATIONS: Older adults who were financially secure, worried about their financial situation, or wished they could speak with someone about their financial decisions appeared susceptible to falling victim to a fraud attempt. The high number of attempts indicates a need for a measurable and concerted effort to prevent the financial fraud of older adults.
Implementation of a Mobile Health Intervention for Feedback in Newborn Resuscitations: Perceptions and Experiences of Congolese Midwives
Creators: name: Amy Mackay
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Background: Newborn resuscitation training reduces intrapartum-related deaths, but further reductions are limited by poor translation of training to bedside actions. Clinical feedback using a mobile health application like LIVEBORN may enhance translation. LIVEBORN provides real-time guidance (RTG) and supports debriefing for newborn resuscitations.
Objective: Explore the perceptions and experiences of Congolese midwives regarding LIVEBORN for feedback.
Methods: We conducted a 1.5-hour focus group discussion (FGD) at the two facilities with a convenience sample of 6 midwives per facility. One facility used debriefing, and one used RTG. We explored 1) initial impressions, 2) observing births with LIVEBORN, 3) incorporation of LIVEBORN feedback, 4) psychological safety, 5) changes in clinical care, 6) recommendations for optimization, and 7) future use. A trained moderator, Daniel Ishoso, conducted FGDs in French, the local language, and later transcribed audio recordings. Using qualitative content analysis, I coded French transcripts using Nvivo. Two investigators independently created English clusters of codes to identify patterns in the data, grouped clusters into themes, and determined final themes by consensus.
Results: We identified three consistent themes from both facilities: (1) Belief that LIVEBORN feedback could save lives, (2) Challenges observing births with LIVEBORN, and (3) Interest in the future use of LIVEBORN feedback. Four themes emerged regarding debriefing: (1) Facilitation of debriefing by a head nurse midwife during morning meetings, (2) Both discouraged by their mistakes and encouraged to improve, (3) Correction of mistakes and increased self-confidence, and (4) Easy to understand LIVEBORN prompts but some prompts perceived as erroneous. Four themes emerged regarding RTG: (1) Helpful despite some inconsistent guidance, (2) Audio prompts did not feel like a reprimand, (3) Inconsistent adherence to prompts, and (4) Prompts were too quick.
Conclusions: Midwives believed that LIVEBORN feedback could help save newborn lives. The perception of erroneous or inconsistent guidance is a key barrier to effectively implementing automated feedback.

description: We consider the problem of approximating optimal in the Minimum Mean Squared Error (MMSE) sense nonlinear filters in a discrete time setting, exploiting properties of stochastically convergent state process approximations. More specifically, we consider a class of nonlinear, partially observable stochastic systems, comprised by a (possibly nonstationary) hidden stochastic process (the state), observed through another conditionally Gaussian stochastic process (the observations). Under general assumptions, we show that, given an approximating process which, for each time step, is stochastically convergent to the state process, an approximate filtering operator can be defined, which converges to the true optimal nonlinear filter of the state in a strong and well defined sense. In particular, the convergence is compact in time and uniform in a completely characterized measurable set of probability measure almost unity, also providing a purely quantitative justification of Egoroff's Theorem for the problem at hand. The results presented in this paper can form a common basis for the analysis and characterization of a number of heuristic approaches for approximating optimal nonlinear filters, such as approximate grid based techniques, known to perform well in a variety of applications.

description: The lifetime of non-equilibrium electrons and holes in semiconductors is crucial for solar cell and optoelectronic applications. Non-adiabatic molecular dynamics (NAMD) simulations based on time-dependent density functional theory (TDDFT) are widely used to study excited-state carrier dynamics. However, the calculated carrier lifetimes are often different from experimental results by orders of magnitude. In this work, by revisiting the definition of carrier lifetime and considering different recombination mechanisms, we report a systematic procedure for calculating the effective carrier lifetime in realistic semiconductor crystals that can be compared directly to experimental measurements. The procedure shows that considering all recombination mechanisms and using reasonable densities of carriers and defects are crucial in calculating the effective lifetime. When NAMD simulations consider only Shockey-Read-Hall (SRH) defect-assisted and band-to-band non-radiative recombination while neglect band-to-band radiative recombination, and the densities of non-equilibrium carriers and defects in supercell simulations are much higher than those in realistic semiconductors under solar illumination, the calculated lifetimes are ineffective and thus differ from experiments. Using our procedure, the calculated effective lifetime of the halide perovskite CH3NH3PbI3 agrees with experiments. It is mainly determined by band-to-band radiative and defect-assisted non-radiative recombination, while band-to-band non-radiative recombination is negligible. These results indicate that it is possible to calculate carrier lifetimes accurately based on NAMD simulations, but the directly calculated values should be converted to effective lifetimes for comparison to experiments. The revised procedure can be widely applied in future carrier lifetime simulations.

description: We study scaling limits of a family of planar random growth processes in which clusters grow by the successive aggregation of small particles. In these models, clusters are encoded as a composition of conformal maps and the location of each successive particle is distributed according to the density of harmonic measure on the cluster boundary, raised to some power. We show that, when this power lies within a particular range, the macroscopic shape of the cluster converges to a disk, but that as the power approaches the edge of this range the fluctuations approach a critical point, which is a limit of stability. The methodology developed in this paper provides a blueprint for analysing more general random growth models, such as the Hastings-Levitov family.

description: Observation of gravitationally induced entanglement between two massive particles can be viewed as implying the existence of the nonclassical nature of gravity. However, weak interaction in the gravitational field is extremely small so that gravitationally induced entanglement is exceptionally challenging to test in practice. For addressing this key challenge, here we propose a criterion based on the logical contradictions of weak entanglement, which may boost the sensitivity of the signal due to the gravitationally induced entanglement. Specifically, we make use of the weak-value scenario and Einstein-Podolsky-Rosen steering. We prove that it is impossible for a classical mediator to act on two local quantum objects to simulate amplified-weak-value phenomenon in two-setting Einstein-Podolsky-Rosen steering. Our approach can amplify the signal of gravitationally induced entanglement that were previously impossible to observe by any desired factor that depends on the magnitude of the weak value. Our results not only open up the possibility of exploring nonclassical nature of gravity in the near future, but they also pave the way for weak entanglement criterion of a more general nature.
