HD/H2 as a probe of the roles of gas, dust, light, metallicity and cosmic rays in promoting the growth of molecular hydrogen in the diffuse interstellar medium

description: We modelled recent observations of UV absorption of HD and \HH\ in the Milky Way and toward damped/sub-damped Lyman alpha systems at z=0.18 and z $>$ 1.7. N(HD)/N(\HH) ratios reflect the separate self-shieldings of HD and \HH\ and the coupling introduced by deuteration chemistry. Locally, observations are explained by diffuse molecular gas with $ 16 \pccc \la$ n(H) $\la 128 \pccc $ if the cosmic-ray ionization rate per H-nucleus \zetaH $= 2\times 10^{-16}\ps$ as inferred from \H3\p\ and OH\p. The dominant influence on N(HD)/N(\HH) is the cosmic-ray ionization rate with a much weaker downward dependence on n(H) at Solar metallicity, but dust-extinction can drive N(HD) higher as with N(\HH). At z $>$ 1.7, N(HD) is comparable to the Galaxy but with 10x smaller N(\HH) and somewhat smaller N(\HH)/N(H I). Comparison of our Galaxy and the Magellanic Clouds shows that smaller \HH/H is expected at sub-Solar metallicity and we show by modelling that HD/\HH\ increases with density at low metallicity, opposite to the Milky Way. Observations of HD would be explained with higher n(H) at low metallicity but high-z systems have high HD/\HH\ at metallicity 0.04 $\la$ Z $\la$ 2 Solar. In parallel we trace dust-extinction and self-shielding effects. The abrupt \HH\ transition to \HH/H $\approx$ 1-10% occurs mostly from self-shielding although it is assisted by extinction for n(H) $\la 16 \pccc$. Interior \HH\ fractions are substantially increased by dust extinction below $\la 32\pccc$. At smaller n(H), \zetaH, small increases in \HH\ triggered by dust extinction can trigger abrupt increases in N(HD).

description: The third annual workshop for the NSF Division of Advanced Cyberinfrastructure (ACI) CAREER awardees was held June 2 -- 3, 2014 in Arlington, Virginia. Twenty-seven attendees and five keynote speakers attended the workshop. The attendees, who were funded by nine divisions that support research related to the development and use of cyberinfrastructure, were selected from twenty-five institutions. Seven of the attendees of the workshop attended one of the previous workshops (i.e., either the 2012 or the 2013 workshop). Four of the attendees attended both the 2012 and 2013 workshops and returned for this year's workshop. Five keynote presentations were given by nationally- and internationally-recognized leaders in fields relevant to the use and development of cyberinfrastructure in science and engineering research. Each keynote presentation was followed by a discussion session with workshop attendees. The workshop provided a venue for CAREER awardees to interact and to develop new collaborations with leading researchers and other CAREER awardees.

Viscosity prescription for gravitationally unstable accretion disks
Creators: name: Rafikov, Roman R.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Gravitationally unstable accretion disks emerge in a variety of astrophysical contexts - giant planet formation, FU Orioni outbursts, feeding of AGNs, and the origin of Pop III stars. When a gravitationally unstable disk is unable to cool rapidly it settles into a quasi-stationary, fluctuating gravitoturbulent state, in which its Toomre Q remains close to a constant value Q_0~1. Here we develop an analytical formalism describing the evolution of such a disk, which is based on the assumptions of Q=Q_0 and local thermal equilibrium. Our approach works in the presence of additional sources of angular momentum transport (e.g. MRI), as well as external irradiation. Thermal balance dictates a unique value of the gravitoturbulent stress α_{gt} driving disk evolution, which is a function of the local surface density and angular frequency. We compare this approach with other commonly used gravitoturbulent viscosity prescriptions, which specify the explicit dependence of stress α_{gt} on Toomre Q in an ad hoc fashion, and identify the ones that provide consistent results. We nevertheless argue that our Q=Q_0 approach is more flexible, robust, and straightforward, and should be given preference in applications. We illustrate this with a couple of analytical calculations - locations of the snow line and of the outer edge of the dead zone in a gravitoturbulent protoplanetary disk - which clearly show the simplicity and versatility of the Q=Q_0 approach.

description: The Cyber Physical Systems (CPS) program and the National Robotics Initiative (NRI) have proven successful in many ways, from individual success stories to changing the overall dialogue towards a better understanding of the role of computation in the physical world, collaborations between human and machine, and, more broadly, leading the community towards the utilization of this understanding in a variety of application domains.  The goal of this workshop was to understand the synergies between these two programs, ways in which they complement each other and, importantly, consider the question: are there fundamental and broad-­‐reaching opportunities that expand beyond the CPS and NRI programs?
The workshop generally concluded that CPS research has, as a major driver, been able to make formal guarantees about a system, its software, and its interface with the physical world.  The NRI has focused on developing the technologies to put robots into the real world with humans, i.e., co-­‐robotic systems.  As such, these two objectives have many synergies: formal analysis of behaviors with complex specifications operating in uncertain environments, and the coupling between computation and the physical world.  Yet the different perspectives taken by the CPS and NRI communities indicate open areas where scientific advancement could have important applications to science, technology and education.
Filming the evolution of symbiotic novae with VLBI
Creators: name: Giroletti, Marcello
Publisher: name: Zenodo
Year: 2023

description: In symbiotic novae, the material ejected from the surface of the white dwarf (WD) after the thermonuclear runaway drives a strong shock through the dense circumstellar gas produced by the red giant (RG) wind. Recurring symbiotic novae such as V407 Cyg and RS Oph are perfect real-time laboratories for studying physical processes as diverse as accretion, thermonuclear explosions, shock dynamics and particle acceleration; in many ways they are like supernova remnants on fast forward. In this talk, I will present the results of two intensive VLBI campaigns carried out for the two high energy symbiotic novae V407 Cyg and RS Oph, after their explosions in 2010 and 2021, respectively. These campaigns provided a resolved view of the structure of the ejected material and of its evolution, setting unique and independent constraints on the emission mechanisms, the physical processes at work, the presence and location of shock acceleration, the geometry of the system, and the density profile of the RG wind.

description: The large scale structures of the universe will likely be the next leading source of cosmological information. It is therefore crucial to understand their behavior. The Effective Field Theory of Large Scale Structures provides a consistent way to perturbatively predict the clustering of dark matter at large distances. The fact that baryons move distances comparable to dark matter allows us to infer that baryons at large distances can be described in a similar formalism: the backreaction of short-distance non-linearities and of star-formation physics at long distances can be encapsulated in an effective stress tensor, characterized by a few parameters. The functional form of baryonic effects can therefore be predicted. In the power spectrum the leading contribution goes as $\propto k^2 P(k)$, with $P(k)$ being the linear power spectrum and with the numerical prefactor depending on the details of the star-formation physics. We also perform the resummation of the contribution of the long-wavelength displacements, allowing us to consistently predict the effect of the relative motion of baryons and dark matter. We compare our predictions with simulations that contain several implementations of baryonic physics, finding percent agreement up to relatively high wavenumbers such as $k\simeq 0.3\,h\, Mpc^{-1}$ or $k\simeq 0.6\, h\, Mpc^{-1}$, depending on the order of the calculation. Our results open a novel way to understand baryonic effects analytically, as well as to interface with simulations.

description: Berry curvature dipole plays an important role in various nonlinear quantum phenomena. However, the maximum symmetry allowed for nonzero Berry curvature dipole in the transport plane is a single mirror line, which strongly limits its effects in materials. Here, via probing the nonlinear Hall effect, we demonstrate the generation of Berry curvature dipole by applied dc electric field in WTe2, which is used to break the symmetry constraint. A linear dependence between the dipole moment of Berry curvature and the dc electric field is observed. The polarization direction of the Berry curvature is controlled by the relative orientation of the electric field and crystal axis, which can be further reversed by changing the polarity of the dc field. Our Letter provides a route to generate and control Berry curvature dipole in broad material systems and to facilitate the development of nonlinear quantum devices.

description: Wireless systems have proven to be significant productivity enablers in almost every sector of the national economy. Emerging applications such as the Internet of Things, wireless healthcare, and mobile cloud computing are powered by ubiquitous wireless Internet connectivity and fueled by user demands for increased mobility. However, these applications will place greater demands on precious spectrum resources.To ensure the continuation of these benefits to society, new technologies and policies need to be adopted to enable more flexible and efficient access to the wireless spectrum. The Second Enhancing Access to the Radio Spectrum (EARS) Workshop brought together experts from the wireless community including academic researchers, industry professionals, and policy makers to address future barriers to ubiquitous shared spectrum access. The workshop focused on discussion of near- and long-term obstacles to shared spectrum access, recent research discoveries that can enable improved spectrum sharing between wireless devices, and identifying future goals that will ensure wireless technologies continue to enable national productivity and facilitate economic and societal progress.

description: The NSF workshop on Security and Formal Methods, held 19–20 November 2015, brought together developers of formal methods, researchers exploring how to apply formal methods to various kinds of systems, and people familiar with the security problem space. Participants were drawn from universities, industry research organizations, government, and a selected pool of scientists from foreign institutions. We explored how current research results and strategies can provide improved secure systems using contemporary formal methods, and how these goals can shape future refinements to formal methods.
The workshop was organized into four main areas: (i) Hardware architecture, (ii) Operating systems, (iii) Distributed systems, and (iv) Privacy. Each area had an expert area chair (or pair of chairs), who guided discussion and helped to write a section of the report below. Participants were assigned to an area for part of the workshop, with whole group sessions and cross-cutting groups to consider interactions among abstraction layers.
Open-Set Face Identification on Few-Shot Gallery by Fine-Tuning

description: In this paper, we focus on addressing the open-set face identification problem on a few-shot gallery by fine-tuning. The problem assumes a realistic scenario for face identification, where only a small number of face images is given for enrollment and any unknown identity must be rejected during identification. We observe that face recognition models pretrained on a large dataset and naively fine-tuned models perform poorly for this task. Motivated by this issue, we propose an effective fine-tuning scheme with classifier weight imprinting and exclusive BatchNorm layer tuning. For further improvement of rejection accuracy on unknown identities, we propose a novel matcher called Neighborhood Aware Cosine (NAC) that computes similarity based on neighborhood information. We validate the effectiveness of the proposed schemes thoroughly on large-scale face benchmarks across different convolutional neural network architectures.

description: The unusually large NOAA active region 2192, observed in October 2014, was outstanding in its productivity of major two-ribbon flares without coronal mass ejections. On a large scale, a predominantly north-south oriented magnetic system of arcade fields served as a strong, also lateral, confinement for a series of large two-ribbon flares originating from the core of the active region. The large initial separation of the flare ribbons, together with an almost absent growth in ribbon separation, suggests a confined reconnection site high up in the corona. Based on a detailed analysis of the confined X1.6 flare on October 22, we show how exceptional the flaring of this active region was. We provide evidence for repeated energy release, indicating that the same magnetic field structures were repeatedly involved in magnetic reconnection. We find that a large number of electrons was accelerated to non-thermal energies, revealing a steep power law spectrum, but that only a small fraction was accelerated to high energies. The total non-thermal energy in electrons derived (on the order of 10^25 J) is considerably higher than that in eruptive flares of class X1, and corresponds to about 10\% of the excess magnetic energy present in the active-region corona.

Classifying Data Management Plan Guidance using DMPTool
Publisher: name: University of Virginia
Year: 2023
Subjects: research data management

description: Objectives: To understand the kinds of guidance R1 universities give researchers for the development of data management plans by analyzing the themed guidance text they provide in DMPTool.

Methods: DMPTool is a popular open-source online application for writing data management plans using generic and funder-specific templates. Institutions can become members of DMPTool, allowing them to provide their students, faculty, and staff with an institutional login, the ability to request feedback on their plans, and access to institution-specific guidance. 92% of R1 universities are members of DMPTool and 48% provide guidance for at least one of the 14 data management themes available in DMPTool, such as data format or preservation. This makes DMPTool a convenient source to examine the data management guidance research-intensive American universities are providing their constituents, which would otherwise likely be limited to their respective websites. For this study, themed guidance text provided by 70 R1 universities was copied from DMPTool into Excel. Each link in the text blocks was then coded according to which of nine destination types it pointed to, such as a library website, university research website, or an outside resource. The average text length and number of links were compiled, as well as the most popular guidance themes and the most common linked resources.

Results: The analysis of 490 themed guidance text blocks from 70 R1 institutions showed that guidance text length ranged from 2 words to 2,259 words, and the largest number of links provided in one text block was 31. Universities provided guidance on an average of 6.93 out of the 14 possible themes. Data sharing was the most common theme, while data collection was the least common. The three most common link destinations were the university’s library website, an independent outside resource, and a university research website, and the three most shared outside resources were re3data, the journal Nature, and DataOne.

Conclusions: This study found a wide variety of approaches to advising researchers on writing data management plans, from minimal to detailed guidance. Although best practices for research data management exist, there is no standard for how to deliver this guidance to researchers, especially in an interactive environment like DMPTool which presents unique challenges for information delivery. The assembled text corpus offers opportunities for further research utilizing topic analysis to evaluate the text on a more granular level. Additionally, this dataset could be compared to a second snapshot taken at a later date to see how data management plan guidance shifts over time or compared to guidance
provided by a different set of institutions.

description: Alternative theories to quantum mechanics motivate important fundamental tests of our understanding and descriptions of the smallest physical systems. Here, using spontaneous parametric downconversion as a heralded single-photon source, we place experimental limits on a class of alternative theories, consisting of classical field theories which result in power-dependent normalized correlation functions. In addition, we compare our results with standard quantum mechanical interpretations of our spontaneous parametric downconversion source over an order of magnitude in intensity. Our data match the quantum mechanical expectations, and do not show a statistically significant dependence on power, limiting on quantum mechanics alternatives which require power-dependent autocorrelation functions.

description: Mealworm protein has the general potential to substitute environmentally less favourable, animal derived raw-materials as a gelling biomaterial for zinc enriched wound healing ointments. However, various factors affecting heat-induced gelation of mealworm protein have not yet been studied in detail. Therefore, we investigated the influence of pH (pH 5.5 and 7.5) and zinc concentration (0 M, 0.1 M and 0.3 M) on rheological properties and gel structure of heat-induced mealworm protein gels. Additionally, we used gel solubility experiments and rheological investigations to study the gels with regard to the involved types of interactions. Generally, all examined samples were able to form heat-induced gels. From gel solubility experiments and temperature sweeps, hydrophobic interactions and hydrogen bonds were found to be dominant in all samples. From higher storage moduli we derive the contribution of additional electrostatic and/or covalent interactions in samples with ZnSO4, while shorter linear viscoelastic regimes and more pronounced intracycle strain stiffening were related to less homogenous and more particulate gel structures. From our results strategies for the customisation of gel properties and gel composition may be deduced, that may advance the potential for future utilisation of mealworm protein in wound dressings.

description: Whether ionization feedback triggers the formation of massive stars is highly debated. Using ALMA 3 mm observations with a spatial resolution of $\sim 0.05$ pc and a mass sensitivity of 1.1 $\rm M_\odot$ beam$^{-1}$ at 20 K, we investigate the star formation and gas flow structures within the ionizing feedback-driven structure, a clump-scale massive ($\gtrsim 1500$ $\rm M_\odot$) bright-rimmed cloud (BRC) associated with IRAS 18290-0924. This BRC is bound only if external compression from ionized gas is considered. A small-scale ($\lesssim1$ pc) age sequence along the direction of ionizing radiation is revealed for the embedded cores and protostars, which suggests triggered star formation via radiation-driven implosion (RDI). Furthermore, filamentary gas structures converge towards the cores located in the BRC's center, indicating that these filaments are fueling mass towards cores. The local core-scale mass infall rate derived from H$^{13}$CO$^+$ $J=1-0$ blue profile is of the same order of magnitude as the filamentary mass inflow rate, approximately 1 $\rm M_\odot$ kyr$^{-1}$. A photodissociation region (PDR) covering the irradiated clump surface is detected in several molecules, such as CCH, HCO$^+$, and CS whereas the spatial distribution stratification of these molecules is indistinct. CCH spectra of the PDR possibly indicate a photoevaporation flow leaving the clump surface with a projected velocity of $\sim2$ km s$^{-1}$. Our new observations show that RDI accompanied by a clump-fed process is operating in this massive BRC. Whether this combined process works in other massive BRCs is worth exploring with dedicated surveys.

description: Unlike covalent two-dimensional (2D) materials like graphene, 2D metals have non-layered structures due to their non-directional, metallic bonding. While experiments on 2D metals are still scarce and challenging, density-functional theory (DFT) provides an ideal approach to predict their basic properties and assist in their design. However, DFT methods have been rarely benchmarked against metallic bonding at low dimensions. Therefore, to identify optimal DFT attributes for a desired accuracy, we systematically benchmark exchange-correlation functionals from LDA to hybrids and basis sets from plane waves to local basis with different pseudopotentials. With 1D chain, 2D honeycomb, 2D square, 2D hexagonal, and 3D bulk metallic systems, we compare the DFT attributes using bond lengths, cohesive energies, elastic constants, densities of states, and computational costs. Although today most DFT studies on 2D metals use plane waves, our comparisons reveal that local basis with often-used PBE exchange-correlation is well sufficient for most purposes, while plane waves and hybrid functionals bring limited improvement compared to the greatly increased computational cost. These results ease the demands for generating DFT data for better interaction with experiments and for data-driven discoveries of 2D metals incorporating machine learning algorithms.

description: We give an exhaustive characterization of singular weak solutions for ordinary differential equations of the form $\ddot{u}\,u + \frac{1}{2}\dot{u}^2 + F'(u) =0$, where $F$ is an analytic function. Our motivation stems from the fact that in the context of hydrodynamics several prominent equations are reducible to an equation of this form upon passing to a moving frame. We construct peaked and cusped waves, fronts with finite-time decay and compact solitary waves. We prove that one cannot obtain peaked and compactly supported traveling waves for the same equation. In particular, a peaked traveling wave cannot have compact support and vice versa. To exemplify the approach we apply our results to the Camassa-Holm equation and the equation for surface waves of moderate amplitude, and show how the different types of singular solutions can be obtained varying the energy level of the corresponding planar Hamiltonian systems.

VOTING COHESION ON CHINA IN THE 9TH EUROPEAN PARLIAMENT

Year: 2022

description: The purpose of this thesis is to study voting cohesion on China in the 9th European Parliament to gain a greater understanding of the vital institution in times of tension in the EU-China relationship. Results show that cohesion in the Parliament stand out to previous research. First, the national delegations are on average more cohesive than the party groups. Second, among the party groups, Verts/ALE and ECR show similar cohesion levels as the centrist groups, while the more radical parties are incohesive. Lastly, the left-right and gal/tan ideological dynamics have a significant effect on cohesion, where gal/tan explains cohesion more than the left-right dynamic. However, a party group’s position on protectionism is the best explanation for cohesion, where those who favor trade liberalization are most cohesive. Based on the results we can understand that there is something special occurring in the Parliament when it comes to voting on China.

description: This study constructs machine learning algorithms that are trained to classify samples using sound symbolism, and then it reports on an experiment designed to measure their understanding against human participants. Random forests are trained using the names of Pokemon, which are fictional video game characters, and their evolutionary status. Pokemon undergo evolution when certain in-game conditions are met. Evolution changes the appearance, abilities, and names of Pokemon. In the first experiment, we train three random forests using the sounds that make up the names of Japanese, Chinese, and Korean Pokemon to classify Pokemon into pre-evolution and post-evolution categories. We then train a fourth random forest using the results of an elicitation experiment whereby Japanese participants named previously unseen Pokemon. In Experiment 2, we reproduce those random forests with name length as a feature and compare the performance of the random forests against humans in a classification experiment whereby Japanese participants classified the names elicited in Experiment 1 into pre-and post-evolution categories. Experiment 2 reveals an issue pertaining to overfitting in Experiment 1 which we resolve using a novel cross-validation method. The results show that the random forests are efficient learners of systematic sound-meaning correspondence patterns and can classify samples with greater accuracy than the human participants.

Computation of measure-valued solutions for the incompressible Euler equations
Creators: name: Lanthaler, Samuel
name: Mishra, Siddhartha
Publisher: name: arXiv
Year: 2014
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: We combine the spectral (viscosity) method and ensemble averaging to propose an algorithm that computes admissible measure valued solutions of the incompressible Euler equations. The resulting approximate young measures are proved to converge (with increasing numerical resolution) to a measure valued solution. We present numerical experiments demonstrating the robustness and efficiency of the proposed algorithm, as well as the appropriateness of measure valued solutions as a solution framework for the Euler equations. Furthermore, we report an extensive computational study of the two dimensional vortex sheet, which indicates that the computed measure valued solution is non-atomic and implies possible non-uniqueness of weak solutions constructed by Delort.

description: During a three-day workshop in February 2012, 45 Information Retrieval researchers met to discuss long-range challenges and opportunities within the field. The result of the workshop is a diverse set of research directions, project ideas, and challenge areas. This report describes the workshop format, provides summaries of broad themes that emerged, includes brief descriptions of all the ideas, and provides detailed discussion of six proposals that were voted "most interesting" by the participants. Key themes include the need to: move beyond ranked lists of documents to support richer dialog and presentation, represent the context of search and searchers, provide richer support for information seeking, enable retrieval of a wide range of structured and unstructured content, and develop new evaluation methodologies.
Pairing versus quarteting coherence length

description: We systematically analyse the coherence length in even-even nuclei. The pairing coherence length in the spin-singlet channel for the effective density dependent delta (DDD) and Gaussian interaction is estimated. We consider in our calculations bound states as well as narrow resonances. It turns out that the pairing gaps given by the DDD interaction are similar to those of the Gaussian potential if one renormalizes the radial width to the nuclear radius. The correlations induced by the pairing interaction have in all considered cases a long range character inside the nucleus and decrease towards the surface. The mean coherence length is larger than the geometrical radius for light nuclei and approaches this value for heavy nuclei. The effect of the temperature and states in continuum is investigated. Strong shell effects are evidenced, especially for protons. We generalize this concept to quartets by considering similar relations, but between proton and neutron pairs. The quartet coherence length has a similar shape, but with larger values on the nuclear surface. We evidence the important role of proton-neutron correlations by estimating the so-called alpha coherence length, which takes into account the overlap with the proton-neutron part of the $α$-particle wave function. It turns out that it does not depend on the nuclear size and has a value comparable to the free $α$-particle radius. We have shown that pairing correlations are mainly concentrated inside the nucleus, while quarteting correlations are connected to the nuclear surface.

Serbia’s delicate balancing act. A case study of Serbia’s foreign policy
Creators: name: Beeker, Bo
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Serbia represents one of the most interesting cases in the Western Balkans when looking at its foreign policy, as it is balancing between the West and Russia: on the one hand, the country began EU accession negotiations in 2014 and established strong ties with European countries and Western organizations; on the other hand, it has deep economic ties and a widely proclaimed “friendship” with Russia. This thesis explores this complex policy strategy in more detail and argues that economic benefits and Serbia’s territorial claim over Kosovo are the main drivers for the country’s balancing act. In researching these two arguments, this thesis is considered a case study, allowing a thorough analysis of the complex and particularistic nature of the country’s position. The methodology involves a combination of social scientific and humanities-based methods: policy analyses, public statements, interviews of Serbian officials, journal articles, and think tank reports are assessed and integrated.

description: Nitrogen-vacancy centers in diamond show great potential as magnetic, electric and thermal sensors which are naturally packaged in a bio-compatible material. In particular, NV-based magnetometers combine small sensor volumes with high sensitivities under ambient conditions. The practical operation of such sensors, however, requires advanced quantum control techniques that are robust with respect to experimental and material imperfections, control errors, and noise. Here, we present a novel approach that uses Floquet theory to efficiently generate smooth and simple quantum control pulses with tailored robustness properties. We verify their performance by applying them to a single NV center and by characterising the resulting quantum gate using quantum process tomography. We show how the sensitivity of NV-ensemble magnetometry schemes can be improved by up to two orders of magnitude by compensating for inhomogeneities in both the control field and the spin transition frequency. Our approach is ideally suited for a wide variety of quantum technologies requiring high-fidelity, robust control under tight bandwidth requirements, such as spin-ensemble based memories involving high-Q cavities.

Application of Machine Learning to Sporadic Experimental Data for Understanding Epitaxial Strain Relaxation

description: Understanding epitaxial strain relaxation is one of the key challenges in functional thin films with strong structure-property relation. Herein, we employ an emerging data analytics approach to quantitatively evaluate the underlying relationships between critical thickness (hc) of strain relaxation and various physical and chemical features, despite the sporadic experimental data points available. First, we have collected and refined reported hc of perovskite oxide thin film/substrate system to construct a consistent sub-dataset which captures a common trend among the varying experimental details. Then, we employ correlation analyses and feature engineering to find the most relevant feature set which include Poisson's ratio and lattice mismatch. With the insight offered by correlation analyses and feature engineering, machine learning (ML) models have been trained to deduce a decent accuracy, which has been further validated experimentally. the demonstrated framework is expected to be efficiently extended to the other classes of thin films in understanding hc.

Test-retest Reliability of Cerebrovascular Measures during the Oral Contraceptive Cycle

description: In vascular testing, women who use oral contraceptives are tested in the placebo phase to control for potential confounding variables. This methodological decision may not be necessary if cerebrovascular measurements are reliable between days in women using oral contraceptives. We measured the reliability of middle cerebral artery blood flow velocity, heart-middle cerebral artery pulse wave velocity, and two cognitive tasks in 13 women, and 5 men on three days within an oral contraceptive cycle (21.49 ± 3.21 years, 72.2% female, 23.78 ± 2.53 kg/m2). Women had better reliability for main outcomes of middle cerebral artery blood flow velocity (ICC: 0.718 v. 0.575) and heart-middle cerebral artery pulse wave velocity (ICC: 0.929 v. 0.844). These results suggest that women using oral contraceptives have similar reliability to men and they could be tested in any cycle phase during future vascular studies.
