description: In this paper, we develop a new method of computing three-point functions in the SU(2) sector of the $\mathcal{N}=4$ super Yang-Mills theory in the semi-classical regime at weak coupling, which closely parallels the strong coupling analysis. The structure threading two disparate regimes is the so-called monodromy relation, an identity connecting the three-point functions with and without the insertion of the monodromy matrix. We shall show that this relation can be put to use directly for the semi-classical regime, where the dynamics is governed by the classical Landau-Lifshitz sigma model. Specifically, it reduces the problem to a set of functional equations, which can be solved once the analyticity in the spectral parameter space is specified. To determine the analyticity, we develop a new universal logic applicable at both weak and strong couplings. As a result, compact semi-classical formulas are obtained for a general class of three-point functions at weak coupling including the ones whose semi-classical behaviors were not known before. In addition, the new analyticity argument applied to the strong coupling analysis leads to a modification of the integration contour, producing the results consistent with the recent hexagon bootstrap approach. This modification also makes the Frolov-Tseytlin limit perfectly agree with the weak coupling form.

title: Perceived environmental barriers and facilitators of refugee children’s physical activity in/around refugee accommodation: a qualitative case study in Berlin
Creators: name: Chen, Siqi

Publisher: name: BioMed Central

description: Background: Previous research have identified built environmental attributes associated with refugee children’s physical activity (PA); however, there is a lack of research focusing on refugee children’s environmental perceptions at the individual level. We examined the perceived environmental barriers and facilitators of refugee children’s PA. Methods: Perceptions of PA environments by refugee children (n = 15, 6 to 13 years old) and their parents (n = 10) were captured by questionnaires and drawing workshops from one refugee accommodation in Berlin. Besides, photovoice was conducted with three children to obtain an in-depth understanding of their experiences of existing environments for PA. Research was applied between June and July 2019. All research material was transcribed and analysed using thematic analysis. Results: Refugee children and their parents identified micro-environments as the centre of children’s daily PA, they usually played indoors but most parents perceived there was no spaces. In meso environments, children and parents thought there were insufficient spaces and were worried about neighbourhood safety. Furthermore, parents concerned more about ‘space accessibility’ for their children’s playing purposes instead of ‘space quality (e.g., equipment)’ . Children also indicated the importance of informal spaces for their PA. Conclusions: Refugee children perceive a lack of space and safety when attempting to play in the existing micro and meso environments. Related practitioners should focus on providing more play spaces in micro environments and safe access to existing neighbourhood playfields. These efforts can augment much-needed research on strategies to better integrate refuge facilities to their urban context and essential in minimising current health and spatial inequality issues these vulnerable groups face across Germany and worldwide.

description: We study two- and three-gluon glueballs of $C=+$ using the method of QCD sum rules. We systematically construct their interpolating currents, and find that all the spin-1 currents of $C=+$ vanish. This suggests that the ``ground-state'' spin-1 glueballs of $C=+$ do not exist within the relativistic framework. We calculate masses of the two-gluon glueballs with $J^{PC} = 0^{\pm+}/2^{\pm+}$ and the three-gluon glueballs with $J^{PC} = 0^{\pm+}/2^{\pm+}$. We propose to search for the $J^{PC} = 0^{-+}/2^{-\pm}/3^{\pm-}$ three-gluon glueballs in their three-meson decay channels in future BESIII, GlueX, LHC, and PANDA experiments.

Small business performance and stock return predictability
Creators: name: Dougal, Casey Mark
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: I find that growth in local proprietary income is positively correlated with the future stock returns and cash flows of public firms headquartered nearby. This predictability is strongest for firms in high-technology industries, for firms with more localized business operations, and when proprietor financial constraints are relaxed as measured by changes in aggregate housing prices. Proprietary income growth also predicts aggregate stock prices. There exists a common proprietary income growth factor across economic regions which pro-cyclically predicts aggregate market returns. This factor is highly correlated with the Silicon Valley proprietary income growth rate---which itself is a stronger predictor of aggregate returns than the dividend yield or CAY.

description: Gamma-ray bursts (GRBs) were confirmed to be of extragalactic origin due to their isotropic angular distribution, combined with the fact that they exhibited an intensity distribution that deviated strongly from the $-3/2$ power law. This finding was later confirmed with the first redshift, equal to at least $z=0.835$, measured for GRB970508. Despite this result, the data from $CGRO$/BATSE and $Swift$/BAT indicate that long GRBs are indeed distributed isotropically, but the distribution of short GRBs is anisotropic. $Fermi$/GBM has detected 1669 GRBs up to date, and their sky distribution is examined in this paper. A number of statistical tests is applied: nearest neighbour analysis, fractal dimension, dipole and quadrupole moments of the distribution function decomposed into spherical harmonics, binomial test, and the two point angular correlation function. Monte Carlo benchmark testing of each test is performed in order to evaluate its reliability. It is found that short GRBs are distributed anisotropically on the sky, and long ones have an isotropic distribution. The probability that these results are not a chance occurence is equal to at least 99.98\% and 30.68\% for short and long GRBs, respectively. The cosmological context of this finding and its relation to large-scale structures is discussed.

description: The merger-driven Gamma-ray Bursts (GRBs) and their associated gravitational wave (GW) radiation, if both successfully detected, have some far-reaching implications, including for instance: (i) The statistical comparison of the physical properties of the short/long-short GRBs with and without GW detection can test the general origin model; (ii) Revealing the physical processes taking place at the central engine; (iii) Measuring the velocity of the Gravitational wave directly/accurately. In this work we discuss these implications in the case of possible association of GW150914/ GBM transient 150914. We compared GBM transient 150914 with other SGRBs and found that such an event {may be} a distinct outlier in some statistical diagrams, possibly due to its specific binary-black-hole merger origin. However, the presence of a "new" group of SGRBs with "unusual" physical parameters is also possible. If the outflow of GBM transient 150914 was launched by the accretion onto the nascent black hole, the magnetic activity rather than the neutrino process is likely responsible for the energy extraction and the accretion disk mass is estimated to be $\sim 10^{-5}~M_\odot$. The GW150914/GBM transient 150914 association, {if confirmed, would} provide the first opportunity to directly measure the GW velocity and its departure from the speed of the light {should be within} a factor of $\sim 10^{-17}$.

description: Reservoir computing is a temporal information processing system that exploits artificial or physical dissipative dynamics to learn a dynamical system and generate the target time-series. This paper proposes the use of real superconducting quantum computing devices as the reservoir, where the dissipative property is served by the natural noise added to the quantum bits. The performance of this natural quantum reservoir is demonstrated in a benchmark time-series regression problem and a practical problem classifying different objects based on temporal sensor data. In both cases the proposed reservoir computer shows a higher performance than a linear regression or classification model. The results indicate that a noisy quantum device potentially functions as a reservoir computer, and notably, the quantum noise, which is undesirable in the conventional quantum computation, can be used as a rich computation resource.
Robust Clustering Methods with Subpopulation-specific Deviations
Creators: name: Stephenson, Briana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Large populations have been found to be composed of a unique set of subpopulations. Each subpopulation tends to exhibit similar behaviors and respond to various outcomes different from other subpopulations. Mixture models have become a great utility in modeling these differences, by attributing each subpopulation its own unique distribution. The underlying subpopulation inferred from the mixture model is referred to as a latent class or cluster.
      Traditional clustering methods operate under the assumption that two subjects allocated to the same cluster will respond identically to all measured variables. Yet, aberrations between some individual measured variables can yield valuable information. Furthermore, these models often realize an increasing number of clusters that expand with the dimensionality of sample size and number of variables. This may lead to a loss in interpretability, due to a large number of clusters and an oversensitivity to minor deviations that exist among groups.
      First, we develop a parsimonious clustering method to address these complexities. Motivated from a local partition process framework, we propose a new method known as Robust Profile Clustering (RPC) that allows subjects to aggregate at two levels: (1) globally, where subjects are allotted to overall population-level clusters and (2) locally, where individual measured items can deviate from their global indicators via a Beta-Bernoulli process to adapt for differences across groups of individuals.
      Second, we build upon this to create a predictive clustering model that links the clustering model generated from the RPC with a response probit model via a supervised RPC joint model. Here, subjects more likely to exhibit the outcome of interest can cluster in accordance with her global and local profiles.
      Finally, we discuss the impact and practicality of these methods, as well as other recent machine learning techniques in nutritional epidemiology to improve dietary pattern analysis in large heterogeneous populations, such as the United States, while adjusting for potential state-level differences. Using data obtained from the 1997-2009 National Birth Defects Prevention Study, we focus our application towards maternal diet and its association to oral cleft birth defects.

description: We propose and analyze an all-magnetic scheme to perform a Young's double slit experiment with a micron-sized superconducting sphere of mass $\gtrsim {10}^{13}$ amu. We show that its center of mass could be prepared in a spatial quantum superposition state with an extent of the order of half a micrometer. The scheme is based on magnetically levitating the sphere above a superconducting chip and letting it skate through a static magnetic potential landscape where it interacts for short intervals with quantum circuits. In this way, a protocol for fast quantum interferometry using quantum magnetomechanics is passively implemented. Such a table-top earth-based quantum experiment would operate in a parameter regime where gravitational energy scales become relevant. In particular, we show that the faint parameter-free gravitationally-induced decoherence collapse model, proposed by Diósi and Penrose, could be unambiguously falsified.

Novel roles for adenomatous polyposis coli family members and wingless signaling in cell adhesion and axon outgrowth during Drosophila brain development
Creators: name: Hayden, Melissa Annette
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: Mutation in the tumor suppressor gene, adenomatous polyposis coli (APC), leads to the initiation of colon cancer. Both Drosophila and mammals have two APC family members, APC1 and APC2. Our lab and others have characterized both Drosophila family members in the developing embryonic epidermis. In addition, we characterized the expression of both in the developing larval brain. Construction of the brain is one of the most complex developmental challenges. Wnt signals shape all tissues, including the brain, and the APC is a key negative regulator of Wnt/Wingless (Wg) signaling. We carried out the first assessment of the role of APC proteins in brain development, simultaneously inactivating both APC1 and APC2 in clones of cells in the Drosophila larval optic lobe. Loss of both APCs triggers dramatic defects in optic lobe development. Double mutant cells segregate from wild-type neighbors to form epithelial "loops", while double mutant neurons form tangled axonal "knots", suggesting changes in cell adhesion. Activation of Wg signaling downstream of APC mimics these phenotypes, a dominant-negative TCF construct blocks them, and a known Wg target, Decapentaplegic, is activated in double mutant clones. These results strongly suggest that the phenotypes result from activated Wg signaling. We also explored the roles of classic cadherins in differential adhesion. Finally, we propose a model suggesting that Wg signaling regulates fine scale cell fates along the anterior-posterior axis in the developing larval brain, in part by creating an adhesion gradient.

description: Sedentary behavior (SB) accounts for 7.5 % of cardiometabolic mortality globally. The burden of cardiometabolic disease is especially high among Latino middle-aged and older adults and they do not meet PA guidelines and spend much time in SB. The study used baseline data from the Physical Activity Program to Disrupt Sedentary Time in Older Latinos (PAIS) and consists of two parts. The first part of the study included PAIS baseline interviews of 39 Latino middle-aged and older adult participants to identify the themes pertaining to the barriers and facilitators of PA and clarify themes describing SB and PA experiences in this population by using the thematic content analysis approach. The results revealed four major themes included: (1) the meaning of SB, (2) the barriers of PA, (3) the motivators/facilitators of PA, and (4) the consequences of sedentary behavior and PA. In the second part of the study, descriptive correlational analyses were conducted by using data from 39 Latino middle-aged and older adult participants from PAIS study. This study assessed the relationship between PA (7-day step count), age, total number of years of education, sedentary bouts, and executive function. PA and sedentary bout were measured by 7-day actigraphy. Executive function was measured by oral Trail Making Test Part B (TMT-B). Bivariate correlational analysis and multiple regression analysis were conducted. Based on the findings of the second part of the study, the number of years of education had a significant impact on executive function (b -.13, t[33]=-5.40, p<.001). Age, 7-day step count, and total number of sedentary bouts have a non-significant effect on TMT-B score. There were also regression limitations due to the sample size, whereas some variables may have been moderator variables. The findings of these analyses indicated that the Latino population has a diverse culture thus, we should consider all Latinos, rather than limiting samples to certain regions, a follow-up longitudinal study should be conducted, and further studies with larger sample sizes are needed to increase the power of the analyses. Finally, these findings can contribute to developing culturally appropriate interventions to improve physical and executive function.
The Influence of Autonomic Imbalance on Diesel Exhaust-Induced Cardiac Dysfunction in Heart Failure-Prone Rats
Creators: name: Carll, Alex Perrow
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: Short-term exposure to vehicular emissions is strongly associated with adverse cardiac events. Diesel exhaust (DE) is a ubiquitous air pollutant hypothesized to provoke adverse cardiac events partly through defective co-ordination of the sympathetic and parasympathetic branches of the autonomic nervous system. To investigate this putative mechanism, cardiophysiologic responses to a single DE inhalation exposure (500 μg/m3, 4 h, whole-body) were examined in heart failure-prone rats and age-related susceptibility or autonomic challenges were incorporated to reveal latent effects. Challenges included sympathetic stimulation (dobutamine) with and without parasympathetic ablation (vagotomy) and, separately, treadmill exercise and pretreatment with a sympathetic or parasympathetic inhibitor. Measures of cardiac function by left ventricular (LV) pressure and echocardiography, autonomic balance by heart rate (HR) and HR variability (HRV), electrocardiogram, and aortic pressure were performed. DE increased cardiac output, bradyarrhythmias, and parasympathetic tone while altering ventricular repolarization in aged heart failure-prone rats during or shortly after exposure. Exercise also revealed a DE-induced increase in parasympathetic tone in young adult rats shortly after exposure. At 1 day post-exposure, dobutamine and treadmill challenges indicated that DE increased sympathetic influence, but pre-treatment with autonomic inhibitors prevented this. Only sympathetic inhibition prevented a DE-induced decline in contractility and systolic blood pressure at exercise 1 day after exposure. Vagotomy revealed that DE caused systolic and diastolic dysfunction and altered diastolic and chronotropic responses to dobutamine through impaired parasympathetic regulation. Thus, altered autonomic regulation of the heart, characterized by an early parasympathetic dominance and a delayed sympathetic dominance, mediates adverse cardiac effects of air pollution exposure. This research elucidates a major physiologic mechanism driving the adverse health effects of air pollutant exposure. Consequently, these findings will inform health risk assessments, medical therapies, and environmental controls for air pollution.

description: By employing the exact diagonalization method, we investigate the high-harmonic generation (HHG) of the correlated systems under the strong laser irradiation. For the extended Hubbard model on a periodic chain, HHG close to the quantum critical point (QCP) is more significant compared to two neighboring gapped phases (i.e., charge-density-wave and spin-density wave states), especially in low-frequencies. We confirm that the systems in the vicinity of the QCP are supersensitive to the external field and more optical-transition channels via excited states are responsible for HHG. This feature holds the potential of obtaining high-efficiency harmonics by making use of materials approaching to QCP. Based on two-dimensional Haldane model, we further propose that the even- or odd-order components of generated harmonics can be promisingly regarded as spectral signals to distinguish the topologically ordered phases from locally ordered ones. Our findings in this work pave the way to achieve ultrafast light source from HHG in strongly correlated materials and to study quantum phase transition by nonlinear optics in strong laser fields.

When can we judge?

description: This paper is an inquiry into the ethics of moral judgments. Judging is an activity, which has special moral significance because it deals directly with the workings of the moral system. A lot has been said about the person being judged - how we can determine whether an action is wrong or whether the agent is responsible, for instance. But not enough attention has been paid to the person making the judgments. In this paper, I will explore these questions: Do we need a standing to make moral judgments? What does it amount to? What is its basis? I will argue that there are at least three important criteria: knowledge, stake, and purity, and that each has an independent basis. To judge only when one has proper standing is to fully appreciate the role of the self in a moral community, and how the self is to relate to the other.

description: We revisit the classical problem of flow of electrolyte solutions through charged capillary nanopores or nanotubes as described by the capillary pore model (also called "space charge" theory). This theory assumes very long and thin pores and uses a one-dimensional flux-force formalism which relates fluxes (electrical current, salt flux, fluid velocity) and driving forces (difference in electric potential, salt concentration, pressure). We analyze the general case with overlapping electric double layers in the pore and a nonzero axial salt concentration gradient. The 3$\times$3 matrix relating these quantities exhibits Onsager symmetry and we report a significant new simplification for the diagonal element relating axial salt flux to the gradient in chemical potential. We prove that Onsager symmetry is preserved under changes of variables, which we illustrate by transformation to a different flux-force matrix given by Gross and Osterle (1968). The capillary pore model is well-suited to describe the nonlinear response of charged membranes or nanofluidic devices for electrokinetic energy conversion and water desalination, as long as the transverse ion profiles remain in local quasi-equilibrium. As an example, we evaluate electrical power production from a salt concentration difference by reverse electrodialysis, using an efficiency vs. power diagram. We show that since the capillary pore model allows for axial gradients in salt concentration, partial loops in current, salt flux or fluid flow can develop in the pore. Predictions for macroscopic transport properties using a reduced model where the potential and concentration are assumed to be invariant with radial coordinate ("uniform potential" or "fine capillary pore" model), are close to results of the full model.

description: Cervical cancer is a major health concern for women, ranking as the fourth most common cancer and a significant cause of cancer-related deaths worldwide. To enhance prognostic predictions for locally advanced cervical squamous cell carcinoma, we conducted a study utilizing radiomics features extracted from pretreatment magnetic resonance images. The goal was to predict patient survival and compare the predictive value of these features with clinical traits and the 2018 International Federation of Obstetrics and Gynecology (FIGO) staging system. In our retrospective cohort study, we included 500 patients with confirmed cervical squamous cell carcinoma ranging from FIGO stages IIB to IVA under the 2018 staging system. All patients underwent pelvic magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) before receiving definitive curative concurrent chemoradiotherapy (CCRT). The results showed that the combination model, incorporating radiomics scores and clinical traits, demonstrated superior predictive accuracy compared to the widely used 2018 FIGO staging system for both progression-free and overall survival. Age was identified as a significant factor influencing survival outcomes. Additionally, primary tumor invasion stage, tumor maximal diameter, and the location of lymph node metastasis were found to be important predictors of progression-free survival, while primary tumor invasion stage and lymph node metastasis position individually affected overall survival. During the follow-up period, a portion of patients experienced disease-related deaths or tumor progression/recurrence in both sets. The radiomics score significantly enhanced prediction ability, providing valuable insights for guiding personalized therapy approaches and stratifying patients into low- and high-risk categories for progression-free and overall survival. In conclusion, our study demonstrated the potential of radiomics features as a valuable addition to existing clinical tools like the FIGO staging system, offering promising advancements in managing locally advanced cervical squamous cell carcinoma.

description: A causal structure is a relationship between observed variables that in general restricts the possible correlations between them. This relationship can be mediated by unobserved systems, modelled by random variables in the classical case or joint quantum systems in the quantum case. One way to differentiate between the correlations realisable by two different causal structures is to use entropy vectors, i.e., vectors whose components correspond to the entropies of each subset of the observed variables. To date, the starting point for deriving entropic constraints within causal structures are the so-called Shannon inequalities (positivity of entropy, conditional entropy and conditional mutual information). In the present work we investigate what happens when non-Shannon entropic inequalities are included as well. We show that in general these lead to tighter outer approximations of the set of realisable entropy vectors and hence enable a sharper distinction of different causal structures. Since non-Shannon inequalities can only be applied amongst classical variables, it might be expected that their use enables an entropic distinction between classical and quantum causal structures. However, this remains an open question. We also introduce techniques for deriving inner approximations to the allowed sets of entropy vectors for a given causal structure. These are useful for proving tightness of outer approximations or for finding interesting regions of entropy space. We illustrate these techniques in several scenarios, including the triangle causal structure.

description: A simplified model has previously described the inductive charging of colliding identical grains in the presence of an external electric field. Here we extend that model by including heterogeneous surface charge distributions, grain rotations and electrostatic interactions between grains. We find from this more realistic model that strong heterogeneities in charging can occur in agitated granular beds, and we predict that shielding due to these heterogeneities can dramatically alter the charging rate in such beds.

description: A subspace bitrade of type $T_q(t,k,v)$ is a pair $(T_0,T_1)$ of two disjoint nonempty collections of $k$-dimensional subspaces of a $v$-dimensional space $V$ over the finite field of order $q$ such that every $t$-dimensional subspace of $V$ is covered by the same number of subspaces from $T_0$ and $T_1$. In a previous paper, the minimum cardinality of a subspace $T_q(t,t+1,v)$ bitrade was established. We generalize that result by showing that for admissible $v$, $t$, and $k$, the minimum cardinality of a subspace $T_q(t,k,v)$ bitrade does not depend on $k$. An example of a minimum bitrade is represented using generator matrices in the reduced echelon form. For $t=1$, the uniqueness of a minimum bitrade is proved.

Concentrated Poverty and College Outcomes: A Matched Pairs Analysis of Neighborhood Effects
Creators: name: Levy, Brian Louis
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: Does neighborhood disadvantage affect an individual's odds of matriculating at and graduating from college? Research on postsecondary outcomes tends to be non- experimental in nature and finds diminished neighborhood effects when compared to research on secondary outcomes. The limited experimental research focuses only on matriculation and yields contradictory findings. This research uses propensity score matching to account for neighborhood endogeneity and analyze the impact of residing in concentrated poverty during adolescence on college outcomes. The research also assesses institutional, collective socialization, relative deprivation, and epidemic models as mediators for neighborhood effects. Results suggest that concentrated poverty negatively impacts college outcomes, with the strongest effect on college graduation. The mechanisms by which neighborhoods affect collegiate outcomes differ over the life course. The strong, negative impact of neighborhood poverty on college graduation is explained by neighborhood economic opportunity, offering support for collective socialization theory.

description: We study a particular kind of fiber type contractions between complex, projective, smooth varieties f:X->Y, called Fano conic bundles. This means that X is a Fano variety, and every fiber of f is isomorphic to a plane conic. Denoting by rho_{X} the Picard number of X, we investigate such contractions when rho_{X}-rho_{Y} is greater than 1, called non-elementary. We prove that rho_{X}-rho_{Y} is at most 8, and we deduce new geometric information about our varieties, depending on rho_{X}-rho_{Y}. Moreover, when X is locally factorial with canonical singularities and with at most finitely many non-terminal points, we consider fiber type K_{X}-negative contractions f:X->Y with one-dimensional fibers, and we show that rho_{X}-rho_{Y} is at most 9.

THE INFLUENCE OF PARTISAN CONFLICT ON POLICY ATTITUDES
Creators: name: Atkinson, Mary Layton

description: The central question the project asks is to what degree are policy attitudes shaped by aversion to partisan conflict versus the substance of proposed legislation? I argue that the tenor of elite debate--which is often highlighted by the news media and characterized by them as combative--acts as a powerful signal that shapes public policy opinion in predictable ways. The news media's focus on heated partisan debate can erode public support for policies associated with it because many Americans view such conflict as a sign of dysfunction in the government. Each of the articles that comprise the dissertation uses a different methodological approach to test this hypothesis: a natural experiment, a controlled experiment, and an aggregate level examination of the relationship between policy debate in the news and policy-specific mood over time. I find that approximately two-thirds of policy-focused news reports employ a conflict frame that highlights precisely the elements of the lawmaking process that many Americans dislike. Further, I find that the public responds more negatively to policies associated with partisan conflict, even when controlling for factors related to the substance of the bill and to individual's underlying policy preferences. These findings are of importance for lawmakers and scholars of public opinion alike. They suggest that to fully understand patterns of public policy opinion we must examine attitudes toward the substance of policies and the process of lawmaking.
PIC Simulations of the Effect of Velocity Space Instabilities on Electron Viscosity and Thermal Conduction

description: In low-collisionality plasmas, velocity-space instabilities are a key mechanism providing an effective collisionality for the plasma. We use particle-in-cell (PIC) simulations to study the interplay between electron and ion-scale velocity-space instabilities and their effect on electron pressure anisotropy, viscous heating, and thermal conduction. The adiabatic invariance of the magnetic moment in low-collisionality plasmas leads to pressure anisotropy, $p_{\perp,j} > p_{||,j}$, if the magnetic field $\vec{B}$ is amplified ($p_{\perp,j}$ and $p_{||,j}$ denote the pressure of species $j$ [electron, ion] perpendicular and parallel to $\vec{B}$). If the resulting anisotropy is large enough, it can in turn trigger small-scale plasma instabilities. Our PIC simulations explore the nonlinear regime of the mirror, ion-cyclotron, and electron whistler instabilities, through continuous amplification of the magnetic field $|\vec{B}|$ by an imposed shear in the plasma. In the regime $1 \lesssim β_j \lesssim 20$ ($β_j \equiv 8πp_j/|\vec{B}|^2$), the saturated electron pressure anisotropy, $Δp_e/p_{||,e}$, is determined mainly by the (electron-lengthscale) whistler marginal stability condition, with a modest factor of $\sim 1.5-2$ decrease due to the trapping of electrons by the mirrors. We explicitly calculate the mean free path of the electrons and ions along the mean magnetic field and provide a simple physical prescription for the mean free path and thermal conductivity in low-collisionality $β_j \gtrsim 1$ plasmas. Our results imply that velocity-space instabilities likely decrease the thermal conductivity of plasma in the outer parts of massive, hot, galaxy clusters. We also discuss the implications of our results for electron heating and thermal conduction in low-collisionality accretion flows onto black holes, including Sgr A* in the Galactic Center.
