Magnetized Interstellar Molecular Clouds. I. Comparison Between Simulations and Zeeman Observations

description: The most accurate measurements of magnetic fields in star-forming gas are based on the Zeeman observations analyzed by Crutcher et al. (2010). We show that their finding that the 3D magnetic field scales approximately as density$^{0.65}$ can also be obtained from analysis of the observed line-of-sight fields. We present two large-scale AMR MHD simulations of several thousand $M_\odot$ of turbulent, isothermal, self-gravitating gas, one with a strong initial magnetic field (Alfven Mach number $M_{A,0}= 1$) and one with a weak initial field ($M_{A,0}=10$). We construct samples of the 100 most massive clumps in each simulation and show that they exhibit a power-law relation between field strength and density in excellent agreement with the observed one. Our results imply that the average field in molecular clumps in the interstellar medium is $ \sim 42 n_{H,4}^{0.65} μ$G. Furthermore, the median value of the ratio of the line-of-sight field to density$^{0.65}$ in the simulations is within a factor of about (1.3, 1.7) of the observed value for the strong and weak field cases, respectively. The median value of the mass-to-flux ratio, normalized to the critical value, is 70% of the line-of-sight value. This is larger than the 50% usually cited for spherical clouds because the actual mass-to-flux ratio depends on the volume-weighted field, whereas the observed one depends on the mass-weighted field. Our results indicate that the typical molecular clump in the ISM is significantly supercritical (~ factor of 3). The results of our strong-field model are in very good quantitative agreement with the observations of Li et al. (2009), which show a strong correlation in field orientation between small and large scales. Because there is a negligible correlation in the weak-field model, we conclude that molecular clouds form from strongly magnetized (although magnetically supercritical) gas.

Scenes modulate object processing before interacting with memory templates

description: When searching for relevant objects in our environment (say, an apple) we create a memory template (a red sphere), which causes our visual system to favor template-matching visual input (apple-like objects) at the expense of template-mismatching visual input (e.g., leaves). While this principle seems straightforward in a lab-setting, it poses a problem in naturalistic viewing: Two objects that produce the same size on the retina will differ in real-world size if one is nearby and the other is far away. Using the Ponzo illusion to manipulate perceived size while keeping retinal size constant, we demonstrate (across 71 subjects) that visual objects attract attention when their perceived size matches a memory template, compared to mismatching objects that encompass the same size on the retina. This shows that memory templates impact visual selection after object representations are modulated by scene context, thus providing a working mechanism for template-based search in naturalistic vision.

description: We present 3D Particle-in-Cell (PIC) modeling of an ultra-intense laser experiment by the Extreme Light group at the Air Force Research Laboratory (AFRL) using the PIC code LSP. This is the first time PIC simulations have been performed in 3D for this experiment which involves an ultra-intense, short-pulse (30 fs) laser interacting with a water jet target at normal incidence. These 3D PIC simulation results are compared to results from 2D(3$v$) PIC simulations for both $5.4~\cdot~10^{17}$ W cm$^{-2}$ and $3~\cdot~10^{17}$ W cm$^{-2}$ intensities. Comparing the 2D(3$v$) and 3D simulation results, the laser-energy-to-ejected-electron-energy conversion efficiencies were comparable, but the angular distribution of ejected electrons show interesting differences with qualitative differences at higher intensity. An analytic plane-wave model is discussed which provides some explanation for the angular distribution and energies of ejected electrons in the 2D(3$v$) simulations. We also performed a 3D simulation with circularly polarized light and found a significantly higher conversion efficiency and peak electron energy, which is promising for future experiments.

Modelling non−covalent interactions and thermal decomposition pathways in oxyanion−containing ionic liquids
Creators: name: Becker, Julian
Publisher: name: Imperial College London
Year: 2023

description: Ionic Liquids (ILs) are versatile materials with applications in academia and industry. The choice of the constituent IL ions depends on the properties required for a specific application. Designing ILs to match application−specific requirements is an exciting but daunting idea due to the vast number of ion combinations and inter−ionic interaction modes. While an understanding of inter−ionic interactions has been developed for some selected ILs, there is a knowledge gap when other ions are considered. This thesis aims to deepen the understanding of interactions in ILs. To this end, we performed density functional theory calculations on oxyanion−containing imidazolium ILs. The conformational space of the relevant ion pairs (IPs) was sampled, and the interactions present were analysed thoroughly. We demonstrate that electrostatics largely defines cation−anion attraction, while weaker interactions (e.g., dispersion and hydrogen bonding) can still be driving local structuring effects. The analysis is briefly extended to IP dimers, allowing for interactions between ions of like charge. The perchlorate anion shows potential for unprecedented anion−anion attraction and forms energetic ILs with a tendency for exothermic decomposition. A variety of thermal perchlorate decomposition pathways leading to the formation of oxygen are modelled, and we demonstrate that anion−anion interactions may have a critical impact on the activation parameters of the thermal decomposition process. Often, ILs are mixed/contaminated with charge−neutral molecular compounds. In a first step, we model the interactions present in ion−molecule heterodimers. The interaction strength strongly depends on the charge distribution of the charge−neutral molecule, and we provide a protocol to estimate the ion−molecule interaction strength from the electrostatic potential of the charge−neutral molecules. We briefly demonstrate how interactions change when the cation and the anion simultaneously interact with each other and with a charge−neutral molecule in an IP−molecule cluster.

description: Bioinformatics is a rapidly evolving field, and keeping track of the connections in the Brazilian bioinformatics community can be challenging. Targeting a small piece of this puzzle, in this poster, we describe the creation of a knowledge graph of the speakers at the Natal Bioinformatics Forum 2023 using Wikidata, a free and open knowledge base that can be read and edited by both humans and machines. We manually modeled the event metadata on the Wikidata GUI, and using Python and WebScraper, we scraped speaker information, which we reconciled with Wikidata using the wdcuration package. We improved the coverage of information about the speaker using the Author Disambiguator tool and the PyOrcidator package, adding connections to the knowledge graph where possible. Notably, most of the information was already available on the platform due to previous curations by the Wikidata metascientific community. By leveraging Wikidata’s 5-star linked open data model, we were able to generate various insightful visualizations. We generated a co-author graph of the speakers showing the collaboration relationships in the community, which highlighted Prof. Ana Tereza Vasconcelos as a collaboration “hub” in the network. Additionally, we gained insights about the speakers related to their topics of interest, the software and programming languages they have used, and their affiliations. The queries' result and source code are available in a real-time dashboard at https://lubianat.github.io/natal_bioinformatics2wikidata/ . Our approach demonstrates a powerful way to analyze academic events in bioinformatics, bringing connections in the community to light and providing stepping stones for collaborations. We encourage others to use Wikidata to build their own knowledge graphs of events and communities and make ourselves available to help where needed.

Next Steps in Immuno-Oncology: Enhancing Antitumor Effects Through Appropriate Patient Selection and Rationally Designed Combination Strategies
Creators: name: Salama,
name: Moschos,
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Background: Cancers escape immune surveillance via distinct mechanisms that involve central (negative selection within the thymus) or peripheral (lack of costimulation, receipt of death/anergic signals by tumor, immunoregulatory cell populations) immune tolerance. During the 1990s, moderate clinical benefit was seen using several cytokine therapies for a limited number of cancers. Over the past 20 years, extensive research has been performed to understand the role of various components of peripheral immune tolerance, with the co-inhibitory immune checkpoint molecules cytotoxic T-lymphocyte antigen 4 (CTLA-4), programmed death 1 (PD-1), and its ligand (PD-L1) being the most well-characterized at preclinical and clinical levels.

Patients and methods: We used PubMed and Google Scholar searches to identify key articles published reporting preclinical and clinical studies investigating CTLA-4 and PD-1/PD-L1, frequently cited review articles, and clinical studies of CTLA-4 and PD-1/PD-L1 pathway inhibitors, including combination therapy strategies. We also searched recent oncology congress presentations and clinicaltrials.gov to cover the most up-to-date clinical trial data and ongoing clinical trials of immune checkpoint inhibitor (ICI) combinations.

Results: Inhibiting CTLA-4 and PD-1 using monoclonal antibody therapies administered as single agents has been associated with clinical benefit in distinct patient subgroups across several malignancies. Concurrent blockade of CTLA-4 and components of the PD-1/PD-L1 system using various schedules has shown synergy and even higher incidence of durable antitumor responses at the expense of increased rates of immune-mediated adverse events, which can be life-threatening, but are rarely fatal and are reversible in most cases using established treatment guidelines.

Conclusions: Dual immune checkpoint blockade has demonstrated promising clinical benefit in numerous solid tumor types. This example of concurrent modulation of multiple components of the immune system is currently being investigated in other cancers using various immunomodulatory strategies.

description: Objective: The aim of this scope review is to determine the methodological quality of clinical trials in regenerative endodontics following the consort statement. Introduction: As clinical trials in regenerative endodontics are relatively recent, it is intended in this review to examine how these trials are conducted to identify knowledge gaps in this area and redirect future research. Inclusion criteria: This scope review considered participants who underwent regenerative endodontic treatments on necrotic immature teeth. The concept examined was the adherence of the methodological quality of clinical trials published in regenerative endodontics to the 2010 CONSORT statement. This review considered all clinical trials with treatments associated with the context of regenerative endodontic procedures. Methods: The review was registered at OSF database. The initial electronic search was carried out in five electronic databases (PubMed, EMBASE, Web of Science, Cochrane Library and LILACS) until October 2020. Only clinical trials were included. The evaluation of the risk of bias of the studies will be performed with the JBI Critical Appraisal tool. The eligible studies and the data will be extracted by two or more independent reviewers. The data extracted will include specific details about the population, concept, context and study methods of significance to the review question. The adherence of studies to the CONSORT statement will be performed using the CONSORT evaluation tool adapted by Reis et al. (2018) 1. The extracted data will be presented in diagrammatic or tabular form in a manner that aligns with the objectives of this scoping review. Compliance with individual items in the CONSORT statement will be analyzed to determine what researchers should improve when describing clinical trials.

The turbulent destruction of clouds - III. Three dimensional adiabatic shock-cloud simulations

Publisher: name: arXiv
Year: 2015
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We present 3D hydrodynamic simulations of the adiabatic interaction of a shock with a dense, spherical cloud. We compare how the nature of the interaction changes with the Mach number of the shock, $M$, and the density contrast of the cloud, $χ$. We examine the differences with 2D axisymmetric calculations, perform detailed resolution tests, and compare "inviscid" results to those obtained with the inclusion of a $k$-$ε$ subgrid turbulence model. Resolutions of 32-64 cells per cloud radius are the minimum necessary to capture the dominant dynamical processes in 3D simulations, while the 3D inviscid and $k$-$ε$ simulations typically show very good agreement. Clouds accelerate and mix up to 5 times faster when they are poorly resolved. The interaction proceeds very similarly in 2D and 3D - although non-azimuthal modes lead to different behaviour, there is very little effect on key global quantities such as the lifetime of the cloud and its acceleration. In particular, we do not find significant differences in the hollowing or "voiding" of the cloud between 2D and 3D simulations with $M=10$ and $χ=10$, which contradicts previous work in the literature.

We provide a stability version of these results and we discuss their implications on the perturbed thresholds for 2-universality and for a triangle factor. We then turn to the notion of threshold in the context of transversals in hypergraph collections. Here the question is, given a fixed

Manipulation of Human Primary Endothelial Cell and Osteoblast Coculture Ratios to Augment Vasculogenesis and Mineralization
Creators: name: Agrawal, Chandra Mauli
name: Wenke, Joseph C.
name: Shah, Amita R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Tissue-engineering scaffolds are often seeded with a single type of cell, but there has been more focus on cocultures to improve angiogenesis and bone formation for craniofacial applications. Investigation of bone-derived osteoblasts (OBs) is important because of the use of bone grafts and migration of OBs from native bone into constructs in vivo and therefore, their contribution to bone formation in vivo. The limitation of primary OBs has been their inability to mineralize without osteogenic factors in vitro. Through coculture of OBs and endothelial cells (ECs) and manipulation of the coculture ratio, mineralization can be achieved without osteogenic media or additional growth factors, thus enhancing their utility for tissue-engineering applications. An optimal ratio of EC/OB for vasculogenesis and mineralization has not been determined for human primary cells. Human umbilical vein ECs were cultured with normal human primary OBs in different EC/OB ratios, namely, 10:1, 5:1, 1:1, 1:5, and 1:10 with EC and OB monocultures as controls. The number of vasculogenic networks in a collagen matrix was highest in ratios of 5:1 and 1:1. ECs lined up and formed capillary-like networks by day 10, which was not seen in the other groups. On polystyrene, cells were cocultured with ECs and OBs in direct contact (direct coculture) or separated by a transwell membrane (indirect coculture). At day 21, Alizarin Red staining showed mineralization on the 1:5 and 1:10 direct coculture ratios, with 1:5 having more mineralization nodules present than 1:10. No mineralization was seen in other direct coculture ratios or in any of the indirect coculture ratios. Alkaline phosphatase secretion was highest in the 1:5 direct coculture group. Vascular endothelial growth factor secretion from OBs was present in the 1:5 and 1:10 direct coculture ratios at all time points and inhibited after day 1 in other coculture groups. To improve vasculogenesis, cocultures of primary human ECs and OBs in ratios of 5:1 should be used, but to improve bone formation, the 1:5 direct coculture ratio results in most mineralization.

description: Compression garments were initially developed with clinical applications in medical fields, however more recently their use in sporting sectors has increased in popularity. Research has primarily focussed on the utility of compression garments to accelerate physiological recovery, and therefore restoration of baseline performance levels. However, evidence is less clear on whether wearing compression can lead to direct increases in physical performance during exercise or sporting tasks. Therefore, the aim of this systematic review is to investigate the performance enhancement effects of wearing compression garments during exercise or sporting tasks in trained individuals.

description: Motivation: Optimizing seed selection is an important problem in read mapping. The number of non-overlapping seeds a mapper selects determines the sensitivity of the mapper while the total frequency of all selected seeds determines the speed of the mapper. Modern seed-and-extend mappers usually select seeds with either an equal and fixed-length scheme or with an inflexible placement scheme, both of which limit the potential of the mapper to select less frequent seeds to speed up the mapping process. Therefore, it is crucial to develop a new algorithm that can adjust both the individual seed length and the seed placement, as well as derive less frequent seeds. Results: We present the Optimal Seed Solver (OSS), a dynamic programming algorithm that discovers the least frequently-occurring set of x seeds in an L-bp read in $O(x \times L)$ operations on average and in $O(x \times L^{2})$ operations in the worst case. We compared OSS against four state-of-the-art seed selection schemes and observed that OSS provides a 3-fold reduction of average seed frequency over the best previous seed selection optimizations.

description: A stress equilibration procedure for hyperelastic material models is proposed and analyzed in this paper. Based on the displacement‐pressure approximation computed with a stable finite element pair, it constructs, in a vertex‐patch‐wise manner, an H(div)‐conforming approximation to the first Piola‐Kirchhoff stress. This is done in such a way that its associated Cauchy stress is weakly symmetric in the sense that its antisymmetric part is zero tested against continuous piecewise linear functions. Our main result is the identification of the subspace of test functions perpendicular to the range of the local equilibration system on each patch which turn out to be rigid body modes associated with the current configuration. Momentum balance properties are investigated analytically and numerically and the resulting stress reconstruction is shown to provide improved results for surface traction forces by computational experiments.

Bearingless motor

description: This thesis presents the design, implementation, control, and experimental evaluation of a self-sensing hysteresis-type bearingless motor (SSBM). Bearingless motors are well-suited to high-speed applications due to their frictionless operation, but the magnetic levitation of the rotor is unstable without airgap sensors. Eliminating these sensors decreases system cost and volume while increasing system robustness. This work presents the design for a hysteresis-type bearingless motor that operates without the use of airgap sensors. Bearingless motors use a single stator to generate torque and suspension forces to control the position of the rotor. Some measure of the airgap length is needed to enable stable magnetic suspension, so this thesis proposes the injection of a high-frequency carrier signal to the stator windings to amplify the change in coil inductance with rotor position. The coil response is demodulated against the carrier signal to provide an estimate for airgap length. This design uses a stator with 12 independently controlled windings to generate a 4-pole magnetic field for torque and a 2-pole magnetic field to control the rotor suspension. Analytical and finite-element simulation demonstrate that if the current in the windings is controlled, demodulating the winding voltage against the carrier signal gives a good estimate for rotor displacement. When the winding voltage is considered the input, the current through the coils can be used for estimation, but the result is highly dependent on the suspension field. The prototype developed to test this operating principle has been constructed and tested with voltage as the winding input. Inductive sensors are used to provide a "ground truth" signal to evaluate the estimation result and to provide feedback for the rotor suspension while the estimation is being developed. Initial results show that even under voltage control the SSBM prototype is able to estimate the rotor displacement, but only when the suspension control is active. Current control for the system has been developed and will be implemented as the immediate next steps.

Cross-Covariance Functions for Multivariate Geostatistics

description: Continuously indexed datasets with multiple variables have become ubiquitous in the geophysical, ecological, environmental and climate sciences, and pose substantial analysis challenges to scientists and statisticians. For many years, scientists developed models that aimed at capturing the spatial behavior for an individual process; only within the last few decades has it become commonplace to model multiple processes jointly. The key difficulty is in specifying the cross-covariance function, that is, the function responsible for the relationship between distinct variables. Indeed, these cross-covariance functions must be chosen to be consistent with marginal covariance functions in such a way that the second-order structure always yields a nonnegative definite covariance matrix. We review the main approaches to building cross-covariance models, including the linear model of coregionalization, convolution methods, the multivariate Matérn and nonstationary and space-time extensions of these among others. We additionally cover specialized constructions, including those designed for asymmetry, compact support and spherical domains, with a review of physics-constrained models. We illustrate select models on a bivariate regional climate model output example for temperature and pressure, along with a bivariate minimum and maximum temperature observational dataset; we compare models by likelihood value as well as via cross-validation co-kriging studies. The article closes with a discussion of unsolved problems.

Predictions of covariant chiral perturbation theory for nucleon polarisabilities and polarised Compton scattering

description: We update the predictions of the SU(2) baryon chiral perturbation theory for the dipole polarisabilities of the proton, $\{α_{E1},\,β_{M1}\}_p=\{11.2(0.7),\,3.9(0.7)\}\times10^{-4}$fm$^3$, and obtain the corresponding predictions for the quadrupole, dispersive, and spin polarisabilities: $\{α_{E2},\,β_{M2}\}_p=\{17.3(3.9),\,-15.5(3.5)\}\times10^{-4}$fm$^5$, $\{α_{E1ν},\,β_{M1ν}\}_p=\{-1.3(1.0),\,7.1(2.5)\}\times10^{-4}$fm$^5$, and $\{γ_{E1E1},\,γ_{M1M1},\,γ_{E1M2},\,γ_{M1E2}\}_p=\{-3.3(0.8),\,2.9(1.5),\,0.2(0.2),\,1.1(0.3)\}\times10^{-4}$fm$^4$. The results for the scalar polarisabilities are in significant disagreement with semi-empirical analyses based on dispersion relations, however the results for the spin polarisabilities agree remarkably well. Results for proton Compton-scattering multipoles and polarised observables up to the Delta(1232) resonance region are presented too. The asymmetries $Σ_3$ and $Σ_{2x}$ reproduce the experimental data from LEGS and MAMI. Results for $Σ_{2z}$ agree with a recent sum rule evaluation in the forward kinematics. The asymmetry $Σ_{1z}$ near the pion production threshold shows a large sensitivity to chiral dynamics, but no data is available for this observable. We also provide the predictions for the polarisabilities of the neutron: $\{α_{E1},\,β_{M1}\}_n=\{13.7(3.1),\,4.6(2.7)\}\times10^{-4}$fm$^3$, $\{α_{E2},\,β_{M2}\}_n=\{16.2(3.7),\,-15.8(3.6)\}\times10^{-4}$fm$^5$, $\{α_{E1ν},\,β_{M1ν}\}_n=\{0.1(1.0),\,7.2(2.5)\}\times10^{-4}$fm$^5$, and $\{γ_{E1E1},\,γ_{M1M1},\,γ_{E1M2},\,γ_{M1E2}\}_n=\{-4.7(1.1),\,2.9(1.5),\,0.2(0.2),\,1.6(0.4)\}\times10^{-4}$fm$^4$. The neutron dynamical polarisabilities and multipoles are examined too. We also discuss subtleties related to matching dynamical and static polarisabilities.

Systems of interacting diffusions with partial annihilation through membranes

description: We introduce an interacting particle system in which two families of reflected diffusions interact in a singular manner near a deterministic interface $I$. This system can be used to model the transport of positive and negative charges in a solar cell or the population dynamics of two segregated species under competition. A related interacting random walk model with discrete state spaces has recently been introduced and studied in Chen and Fan (2014). In this paper, we establish the functional law of large numbers for this new system, thereby extending the hydrodynamic limit in Chen and Fan (2014) to reflected diffusions in domains with mixed-type boundary conditions, which include absorption (harvest of electric charges). We employ a new and direct approach that avoids going through the delicate BBGKY hierarchy.
