description: Spatial patterning can be crucially important for understanding the behavior of interacting populations. Here we investigate a simple model of parasite and host populations in which parasites are random walkers that must come into contact with a host in order to reproduce. We focus on the spatial arrangement of parasites around a single host, and we derive using analytics and numerical simulations the necessary conditions placed on the parasite fecundity and lifetime for the populations long-term survival. We also show that the parasite population can be pushed to extinction by a large drift velocity, but, counterintuitively, a small drift velocity generally increases the parasite population.

description: Near-Earth asteroids (NEAs) that may evolve into impactors deserve detailed threat assessment studies. Early physical characterization of a would-be impactor may help in optimizing impact mitigation plans. We first detected NEA 2023~DZ$_{2}$ on 27--February--2023. After that, it was found to have a Minimum Orbit Intersection Distance (MOID) with Earth of 0.00005~au as well as an unusually high initial probability of becoming a near-term (in 2026) impactor. We aim to perform a rapid but consistent dynamical and physical characterization of 2023~DZ$_{2}$ as an example of a key response to mitigate the consequences of a potential impact. We use a multi-pronged approach, drawing from various methods (observational/computational) and techniques (spectroscopy/photometry from multiple instruments), and bringing the data together to perform a rapid and robust threat assessment.} The visible reflectance spectrum of 2023~DZ$_{2}$ is consistent with that of an X-type asteroid. Light curves of this object obtained on two different nights give a rotation period $P$=6.2743$\pm$0.0005 min with an amplitude $A$=0.57$\pm$0.14~mag. We confirm that although its MOID is among the smallest known, 2023~DZ$_{2}$ will not impact Earth in the foreseeable future as a result of secular near-resonant behaviour. Our investigation shows that coordinated observation and interpretation of disparate data provides a robust approach from discovery to threat assessment when a virtual impactor is identified. We prove that critical information can be obtained within a few days after the announcement of the potential impactor.

EFFECT OF FATIGUING AND PREHEATING ON THE MECHANICAL PROPERTIES OF BULK-FILL VERSUS CONVENTIONAL COMPOSITE RESIN
Creators: name: Abdulmajeed, Awab
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Objective: To evaluate the effect of fatiguing and preheating on mechanical properties of bulk-fill composite resin and compare it to a conventional composite resin counterpart. Materials and Methods: Hundred and eighty specimen of Filtek One Bulk Fill Restorative (Bulk-Fill) and Filtek Supreme Ultra (Conventional) were prepared for each of the following tests: Fracture Toughness (ISO 6872), Diametral Tensile Strength (No. 27 of ANSI/ADA), Flexural Strength and Elastic Modulus (ISO standard 4049). Specimens in the preheated group were heated to 68º for 10 minutes and in the fatiguing group were cyclically loaded and thermocycled for 600000 cycles and then tested. Statistical analysis was performed using analysis of variance (ANOVA) and Tukey’s multiple comparison tests for pairwise comparisons. Results: Preheating and fatiguing had a significant effect on the properties of both FSU and FOBR. Fracture toughness was increased for FOBR when specimens preheated and decreased when fatigued, FSU was not affected. Diametral tensile strength was decreased significantly after fatiguing for the FSU. FOBR had lower tensile strength for all groups when compared to FSU. Fatiguing significantly reduced flexural strength of both FSU and FOBR with latter significantly different than FSU. Preheating had no effect on the flexural strength of both. Preheating and fatiguing significantly decreased the elastic modulus of both composite resins equally. Conclusions: Preheating and fatiguing has an effect on the mechanical properties of composite resin. Preheating does not yield major negative effect.

description: We take a new look at the curvilinear Hilbert scheme of points on a smooth projective variety $X$ as a projective completion of the non-reductive quotient of holomorphic map germs from the complex line into $X$ by polynomial reparametrisations. Using an algebraic model of this quotient coming from global singularity theory we develop an iterated residue formula for tautological integrals over curvilinear Hilbert schemes.

Publisher: name: Technische Universität Berlin
Year: 1990
Subjects: subject: 530 Physik
subject: nematic liquid crystal
subject: viscosity

description: The viscosity tensor of biaxial-nematic liquid crystals contains 16 independent elements. A complete set of these viscosity coefficients is introduced and related to experimentally accessible quantities. Furthermore, the flow alignment and its stability against an arbitrary infinitesimal disturbance are discussed. By the affine transformation model, formerly established for the uniaxial symmetric case, one can express the viscous anisotropy of perfectly ordered biaxial ellipsoids in terms of the two viscosities of an isotropic reference system and the axes ratios of the nonspherical particles.

Impact and outcomes for drugs and biologicals that have been repurposed as therapy for Covid-19 on the basis of artificial intelligence or machine learning hypotheses
Creators: name: Carlisle, Benjamin

Subjects: subject: Medicine and Health Sciences
subject: Bioethics and Medical Ethics

description: Advocates of artificial intelligence and machine learning in drug repurposing claim that it will increase efficiency, speed development, decrease costs, and protect patient welfare. In the following, we will use systematic review and meta-analytic methods to empirically evaluate the impact and outcomes for drugs and biologicals that have been repurposed as therapy for Covid-19 on the basis of artificial intelligence or machine learning hypotheses. For a cohort of drug repurposing hypotheses that entered the literature between 2020-01-01 and 2020-04-30, we will measure impact in terms of FDA approvals, FDA Emergency Use Authorizations, recommendation in NIH Covid-19 Treatment Guidelines, and positive RCT result within 6 months of follow-up after the first published recommendation of the drug repurposing hypothesis. We will measure trial outcomes in terms of number of trials, patient enrolment, meta-analyzed overall survival hazard ratios, and meta-analyzed proportions for treatment-related deaths and grade 3-4 treatment-related adverse events.
Particle motion in neutron stars ultra-strong electromagnetic field: the influence of radiation reaction

name: Pétri, Jérôme

Year: 2023
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: As a follow-up to our previous work on particle acceleration simulation near neutron stars, in this paper, we discuss the impact of radiation reaction on test particles injected into their magnetosphere. We therefore neglect the interaction between particles through the electromagnetic field as well as gravitation. We integrate numerically the reduced Landau-Lifshitz equation for electrons and protons in the vacuum field of a rotating magnetic dipole based on analytical solutions in a constant electromagnetic field. These expressions are simple in a frame where the electric and magnetic field are parallel. Lorentz transforms are used to switch back and forth between this frame and the observer frame. We found that, though due solely to the Lorentz force, electrons reach Lorentz factors up to $γ=10^{14}$ and protons reach them up to $γ=10^{10.7}$. When radiation reaction is enabled, electrons reach energies up to $γ=10^{10.5}$ and protons reach energies up to $γ=10^{8.3}$. The second set of values are more realistic since the radiation reaction feedback is predominant within the magnetosphere. Moreover, as expected, symmetrical behaviours between the north and south hemispheres are highlighted, either with respect to the location around the neutron star or with respect to particles of opposite charge to mass ratio~$(q/m)$. The study of the influence of the magnetic dipolar moment inclination shows similar behaviours regardless of whether radiation reaction is enabled. Protons (respectively electrons) impact the surface of the neutron star less as the inclination angle increases (decreases for electrons), while if the rotation and magnetic axes are aligned, all the protons impact the neutron star, and all the electrons impact the surface if the rotation and magnetic axes are anti-aligned.

Equilibrium rotation of semiliquid exoplanets and satellites
Creators: name: Makarov, Valeri V.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: A wide range of exoplanet and exomoon models are characterized by a finite average rigidity and a viscosity much lower than the typical values for terrestrials. Such semiliquid bodies may or may not have rigid crusts with permanent figures. Unlike planets with solid mantles and Earth-like rheology, semiliquid bodies can be captured into stable pseudosynchronous spin resonance, where the average rate of rotation is higher than the synchronous 1:1 resonance. Two basic conditions are derived for capture of planets with a triaxial figure into pseudosynchronous rotation, one related to the characteristic tidal wave number (the product of the tidal frequency by the Maxwell time), and the other to the orbital eccentricity. If a semiliquid object does not satisfy either of the two conditions, it is captured into the synchronous resonance. For nearly axially symmetric bodies, only the first condition is in place, and the other is much relaxed, so they should predominantly be pseudosynchronous. It is also pointed out that the equilibrium pseudosychronous rotation rate can not reach the widely used asymptotic value from the constant time lag model but is in reality closer to the synchronous spin.

EVALUATING THE EFFECTS OF AN EDUCATIONAL INTERVENTION ON COMPASSION FATIGUE IN VETERAN AFFAIRS HOSPICE NURSING STAFF
Creators: name: Kritz, Gabriela
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Purpose: The purpose of this preliminary, pre-post, interventional project was to (1) explore the pervasiveness of compassion fatigue & (2) promote self-care activities & evaluate the effectiveness of compassion fatigue education on reducing hospice nursing staffs’ compassion fatigue symptoms in a single hospice care unit.      Background and Rationale: In the nursing profession, staff are at increased risk for compassion fatigue because they frequently witness & are in contact with other people’s suffering, trauma, & pain.  This can lead to many internal and external consequences if not addressed.  Compassion fatigue has been historically under-recognized, understudied, & undertreated. Thus, demonstrating how important projects like this are to retaining caring, compassionate, experienced nurses.        Methodology: The project took place in the hospice unit at the Durham Veteran Affairs Medical Center (DVAMC).  Project participants completed the Professional Quality of Life Tool Version 5 (ProQOL-5), a demographics questionnaire & a self-care habits survey prior to the intervention. Project participants then accessed the continuing education class Compassion Fatigue: Don’t Forget to Care for Yourself When Caring for Others by Connie Vogel via Nurse.com.  The ProQOL-5 & the same self-care habits survey served as the post-intervention assessment & were collected at 30- and 60-days post-intervention.        Results: Only two nursing staff participated at all time periods.  By the end of the study, participant JP21967 increased their compassion satisfaction by 7.32%, decreased their burnout by 20.83% & secondary trauma by 20.69%, & increased their self-care habits.  Participant MA11978 decreased their compassion satisfaction by 11.36%, increased their burnout by 5% & secondary trauma by 13.64%, & decreased their self-care habits.  These findings suggest that the degree to which people engage in self-care may lessen compassion fatigue.      Conclusion: Although the purpose of this study was to reduce compassion fatigue among hospice nurses, context related barriers may have influenced participation.  Further research is needed in the area of compassion fatigue not only for the sake of nurses but also for the sake of healthcare systems.

Subjects: subject: ad hoc

description: The graphics is a redrawing of the old Figure A-1 in the OAIS Reference Model. This drawing has a history of being in a colored form in the CCSDS 650.0-B-1 BLUE BOOK January 2002 version https://public.ccsds.org/Pubs/650x0b1s.pdf (Annex F), but always in black and white in the official version. The 2002 presents itself much nicer than the one in the current version in https://public.ccsds.org/Pubs/650x0m2.pdf (Annex A). The reason is that the 2002 was created on a Macintosh and became unavailable, - therefore the drawing had to be redrawn in order to be included again. The version presented here is improved in several ways: • It re-introduces colors • It presents different graphics for Functions, Functional Entities and Roles • It is consistent with the rest of the figures of OAIS • Placement of Functional Entities as in the well-known Figure 4-1: OAIS Functional Entities • Arrows are highlighted, if they represents arrows from Figure 4-1: OAIS Functional Entities These changes are according to suggestions to the next revision of the OAIS Reference model collected on the OAIS Community Wiki http://wiki.dpconline.org/index.php?title=OAIS_Community. This illustration is produced – not only by hard work – but with artistic brush to make it comprehensible in spite of the many arrows that does not match having the Preservation Planning on top and Administration in the button. This is the current draft of the drawing. It should not be used as a final OAIS drawing, since there are still untreated suggested changes that may influence the final look. The final drawing will be published with the new revision of the OAIS reference model that is currently being prepare. The CCSDS-DAI working group in charge of coordinating the Five Year Review of OAIS (http://review.oais.info/) has on a meeting of the 10th of July 2018 expressed that they have no objections to this submission, as long as it is stressed that it is not the final version and it is not an implementation model.
Simplifying asteroseismic analysis of solar-like oscillators: An application of principal component analysis for dimensionality reduction

description: The asteroseismic analysis of stellar power density spectra is often computationally expensive. The models used in the analysis may use several dozen parameters to accurately describe features in the spectra caused by oscillation modes and surface granulation. Many parameters are often highly correlated, making the parameter space difficult to quickly and accurately sample. They are, however, all dependent on a smaller set of parameters, namely the fundamental stellar properties. We aim to leverage this to simplify the process of sampling the model parameter space for the asteroseismic analysis of solar-like oscillators, with an emphasis on mode identification. Using a large set of previous observations, we applied principal component analysis to the sample covariance matrix to select a new basis on which to sample the model parameters. Selecting the subset of basis vectors that explains the majority of the sample variance, we redefine the model parameter prior probability density distributions in terms of a smaller set of latent parameters. We are able to reduce the dimensionality of the sampled parameter space by a factor of two to three. The number of latent parameters needed to accurately model the stellar oscillation spectra cannot be determined exactly but is likely only between four and six. Using two latent parameters, the method is able to describe the bulk features of the oscillation spectrum, while including more latent parameters allows for a frequency precision better than $\approx10\%$ of the small frequency separation for a given target. We find that sampling a lower-rank latent parameter space still allows for accurate mode identification and parameter estimation on solar-like oscillators over a wide range of evolutionary stages. This allows for the potential to increase the complexity of spectrum models without a corresponding increase in computational expense.

Overview

Del legendario productor musical, un maestro en el arte de ayudar a los demás a conectar con las fuentes de su propia creatividad, llega un libro maravillosamente fraguado a lo largo de muchos años con una visión profunda de la creatividad y de la vida dirigida todo el mundo. «Me propuse a mí mismo escribir un libro acerca de cómo crear una gran obra de arte. En lugar de eso, se reveló como un libro acerca de cómo Ser.» Los grandes productores musicales suelen ser reconocidos por un sonido único que solo ellos son capaces de lograr. Rick Rubin es conocido por eso y por algo más: por saber crear un espacio en el que artistas de diferentes géneros y tradiciones se reencuentran con su identidad profunda y con aquello que realmente tienen que ofrecer al mundo. Rubin ha convertido en una práctica su impulso de ayudar a las personas para que trasciendan expectativas autoimpuestas y reconecten con un estado de inocencia en el que lo sorprendente se convierte en inevitable. A lo largo de los años, Rubin ha pensado mucho en el origen de la creatividad: de dónde viene y de dónde no, y ha aprendido que ser artista no depende tanto de un resultado en concreto, sino de cómo nos relacionamos con el mundo. La creatividad tiene un lugar en la vida de todas las personas y todos podemos hacer ese espacio más grande. De hecho, hay pocas responsabilidades humanas que sean más importantes que esa. El acto de crear es un curso bello y generoso que ilumina el camino del artista como una ruta que todos podemos seguir. Este libro destila la sabiduría recogida durante el trabajo de toda una vida y la convierte en una luminosa experiencia de lectura que tiene el poder de crear momentos —y vidas— de gozo y trascendencia al alcance de todo el mundo.

description: Insight in the crumpling or compaction of one-dimensional objects is of great importance for understanding biopolymer packaging and designing innovative technological devices. By compacting various types of wires in rigid confinements and characterizing the morphology of the resulting crumpled structures, here we report how friction, plasticity, and torsion enhance disorder, leading to a transition from coiled to folded morphologies. In the latter case, where folding dominates the crumpling process, we find that reducing the relative wire thickness counter-intuitively causes the maximum packing density to decrease. The segment-size distribution gradually becomes more asymmetric during compaction, reflecting an increase of spatial correlations. We introduce a self-avoiding random walk model and verify that the cumulative injected wire length follows a universal dependence on segment size, allowing for the prediction of the efficiency of compaction as a function of material properties, container size, and injection force.

The effects of invasive earthworms on understory plant community composition in sugar maple - basswood forests of the Chippewa National Forest, MN over two decades
Creators: name: Alexander, Genevieve
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Non-native earthworms have invaded natural areas in the Great Lakes region of North America and are recognized as a threat to the ecological function and biodiversity of hardwood forests. In Chapter 1, I present a literature review to examine the effects of invasive earthworms on hardwood forests in the Great Lakes region. In Chapter 2, I present a model using the thickness of the O horizon as a predictor variable to assess the presence of invasive earthworms in sugar maple basswood forests in the Chippewa National Forest in Northern Minnesota. In Chapter 3, I examine the effects of invasive earthworms on understory plant community composition over two decades in the Chippewa National Forest. By understanding the effects of invasive earthworms on understory plant composition over multiple decades, the biological consequences of earthworm invasion can be more effectively predicted as invasive earthworms continue to spread across the Great Lakes region.

In this project we are aiming to develop and validate an analogous paradigm for cognitive effort, initially just in healthy participants (see Figure 1). We will analyse performance on the task itself, and also check that participants’ perceived task load accords with the effort levels of the task. Finally, we will also examine the relationship between cognitive effort sensitivity and six trait variables relevant to depression, including anhedonia. This task, like the ‘apple gathering task’ for physical effort, frames effort sensitivity as an economic decision – participants are offered a number of points and an effort level, and then choose whether or not to engage in a subsequent bout of effortful activity. The activity involves categorising each digit in a string of 9 numbers as either even or odd, and the effort level is set by manipulating the number of times the sequence switches from even to odd. Participants weigh the effort required against the points on offer and decide whether the activity is worth doing. If they accept the offer, participants must then perform the subsequent categorisation task accurately in order to win the points. Alternatively, if the offer is deemed to be unattractive and they reject it, they do not perform the task and move straight on to a new offer with a different combination of effort and reward.

description: In previous work, we have proposed an entanglement indicator for a general multiqubit state, which can be "learned" by a quantum system, acting as a neural network. The indicator can be used for a pure or a mixed state, and it need not be "close" to any particular state; moreover, as the size of the system grows, the amount of additional training necessary diminishes. Here, we show that the indicator is stable to noise and decoherence.

A 2 TeV $W_R$, Supersymmetry, and the Higgs Mass

description: A recent ATLAS search for diboson resonances and a CMS search for $eejj$ resonances which both show excesses with significance around 3 sigma have generated interest in $SU(2)_R$ gauge extensions of the Standard Model with a $W'$ mass around 2 TeV. We investigate the possibility that an $SU(2)_R$ gauge extension of the MSSM compatible with an explanation of the diboson anomaly might give rise to a significant enhancement of the Higgs mass above the MSSM tree level bound $m_{h, \text{tree}} < 90 \; \text{GeV}$ due to non-decoupling D-terms. This model contains a vector-like charge -1/3 $SU(2)_R$ singlet quark for each generation which mixes significantly with the $SU(2)_R$ doublet quarks, affecting the $W_R$ phenomenology. We find that it is possible to achieve $m_{h, \text{tree}} > 110 \; \text {GeV}$, and this requires that the $Z'$ mass is close to 3 TeV.

College and Career Readiness of Black Males Mentored by Black Fraternities: A Comparative Case Study
Creators: name: Clark, Keyma
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: The purpose of this dissertation is to investigate how three school-based mentoring programs are preparing African American male youth for post- graduation, college, and careers. The influence of mentoring experiences and mentoring relationships are addressed in order to uncover the influence of racial matching on the mentoring relationship. Mentee and mentor interviews were compared to evaluate the personal perspectives past participation in Chi Omega Lambda, Kappa Leadership, and Theta Phi Psi mentoring advocate program and the mentoring experience. Mentees and mentors expressed overall satisfaction with the mentoring experience and positive comments on the mentoring relationship. The interviews did not reveal differences in the mentoring experience based upon the race of the mentor, but the opportunity for preparing mentees for college and college access differed more for one of the organizations verses the other two.
Pole-Skipping in Rotating BTZ Black Holes

description: Motivated by the connection between pole-skipping phenomena of two point functions and four point out-of-time-order correlators, we study the pole-skipping phenomena for rotating BTZ black holes. In particular, we investigate the effect of rotations on the pole-skipping point for various fields with spin $s = 1/2, 1, 2/3$, extending the previous research for $s=0, 2$. We derive an analytic full tower of the pole-skipping points of fermionic ($s=1/2$) and vector ($s=1$) fields by the exact holographic Green's functions. For the \textit{non-extremal} black hole, the leading pole-skipping frequency is $ω_{\text{leading}}=2πi T_h {(s-1+νΩ)}/{(1-Ω^2)}$ where $T_h$ is the temperature, $Ω$ the rotation, and $ν:=(Δ_+ - Δ_-)/2$, the difference of conformal dimensions ($Δ_{\pm}$). These are confirmed by another independent method: the near-horizon analysis. For the \textit{extremal} black hole, we find that the leading pole-skipping frequency can occur at $ω_{\text{leading}}^{\text{extremal}}=-2πi T_R {(s+1)}$ only when $ν= s+1$, where $T_R$ is the temperature of the right moving mode. It is non-trivial because it cannot be achieved by simply taking the extreme limit ($T_h\rightarrow 0\,, Ω\rightarrow 1$) of the non-extremal black hole result.

description: We study the large-time behavior of solutions to the compressible Navier-Stokes equations for a viscous and heat-conducting ideal polytropic gas in the one-dimensional half-space. A rarefaction wave and its superposition with a non-degenerate stationary solution are shown to be asymptotically stable for the outflow problem with large initial perturbation and general adiabatic exponent.

description: Cells constantly need to monitor the state of the environment to detect changes and timely respond. The detection of concentration changes of a ligand by a set of receptors can be cast as a problem of hypothesis testing, and the cell viewed as a Neyman-Pearson detector. Within this framework, we investigate the role of receptor cooperativity in improving the cell's ability to detect changes. We find that cooperativity decreases the probability of missing an occurred change. This becomes especially beneficial when difficult detections have to be made. Concerning the influence of cooperativity on how fast a desired detection power is achieved, we find in general that there is an optimal value at finite levels of cooperation, even though easy discrimination tasks can be performed more rapidly by noncooperative receptors.
