description: The ATLAS physics program relies on very large samples of GEANT4 simulated events, which provide a highly detailed and accurate simulation of the ATLAS detector. However, this accuracy comes with a high price in CPU, and the sensitivity of many physics analyses is already limited by the available Monte Carlo statistics and will be even more so in the future. Therefore, sophisticated fast simulation tools are developed. In Run-3 we aim to replace the calorimeter shower simulation for most samples with a new parametrized description of longitudinal and lateral energy deposits, including machine learning approaches, to achieve a fast and accurate description. Looking further ahead, prototypes are being developed using cutting edge machine learning approaches to learn the appropriate calorimeter response, which are expected to improve modeling of correlations within showers. Two different approaches, using Variational Auto-Encoders (VAEs) or Generative Adversarial Networks (GANs), are trained to model the shower simulation. Additional fast simulation tools will replace the inner detector simulation, as well as digitization and reconstruction algorithms, achieving up to two orders of magnitude improvement in speed. In this talk, we will describe the new tools for fast production of simulated events and an exploratory analysis of the deep learning methods.

description: Today's most precise optical instruments -- gravitational-wave interferometers and optical atomic clocks -- rely on long storage times for photons to realize their exquisite sensitivity. Optical fiber technology is the most widely deployed platform for realizing long-distance optical propagation. Yet, their application to precision optical measurements is sparse. We review the state-of-the-art in the noise performance of conventional (solid-core) optical fibers from the perspective of precision optical measurements and quantum technology that rely on precise transfer of information over long distances. In doing so, we highlight the limitations of this platform and point to the opportunities that structured fiber technology offers to overcome some of these limitations.

description: It has recently been shown that the phenomenologically successful pattern of cobimaximal neutrino mixing ($θ_{13} \neq 0$, $θ_{23} = π/4$, and $δ_{CP} = \pm π/2$) may be achieved in the context of the non-Abelian discrete symmetry $A_4$, if the neutrino mass matrix is diagonalized by an orthogonal matrix ${\cal O}$. We study how this pattern would deviate if ${\cal O}$ is replaced by an unitary matrix.

Landscape genetics of habitat alteration across multiple spatial and temporal scales in the Anuran genus Ascaphus
Creators: name: Spear, Stephen Frank
Publisher: name: Washington State University
Year: 2009
Subjects: Ascaphus -- Effect of habitat modification on

description: Habitat alteration is considered the single greatest threat to the conservation of natural communities and thus understanding population response to habitat change is critical. In particular, studies are needed that address the effects of disturbance at multiple temporal and spatial scales. In this dissertation, I investigated landscape influence on population genetic structure in the two species of tailed frogs (genus Ascaphus), a pair of stream-associated amphibians that are hypothesized to be especially reliant on mesic forest conditions. This dissertation had three objectives: 1) examine the effect of timber harvest on coastal tailed frog gene flow across a relatively mild climate, 2) investigate patterns of genetic structure in response to both fire and timber harvest in the Rocky Mountain tailed frogs and 3) understand what landscape and environmental factors facilitated colonization of the Mount St. Helens blast zone by coastal tailed frogs. In Chapter 1, I demonstrated that tailed frog populations had high overall genetic connectivity that occurred terrestrially, but loss of forest cover and high solar radiation impeded gene flow in both protected and managed areas. The managed landscape also led to declines in effective population size. In Chapter 2, I detected high gene flow across severely burned areas. However, population connectivity in intensively harvested forests was best explained by movement through riparian corridors that avoided the terrestrial environment. This shift to stream corridors was not seen in coastal tailed frogs in Chapter 1, and suggests an ecological difference between the coastal and Rocky Mountain species. Finally, in Chapter 3, we found high gene flow throughout the Mount St. Helens blast zone and inferred colonization from multiple sources in the outside intact forest. However, environmental influence on gene flow differed among disturbance types, as there was reduced landscape influence on genetic structure in the unmanaged blast zone, but connectivity in the managed blast zone was best described by the effects of several environmental variables. Collectively, this dissertation research demonstrates that dispersal is an important component of tailed frog population structure, and the extent of landscape influence on genetic connectivity is dependent on disturbance type.

description: In this paper, we study uniqueness properties of solutions to the generalized fourth-order Schrödinger equations in any dimension $d$ of the following forms, $$i \partial_t u + \sum_{j=1}^d \partial_{x_j}^{\, 4} u = V(t, x) u, \quad \text{and} \quad i \partial_t u + \sum_{j=1}^d \partial_{x_j}^{\, 4} u + F (u, \bar{u}) = 0.$$ We show that a linear solution $u$ with fast enough decay in certain Sobolev spaces at two different times has to be trivial. Consequently, if the difference between two nonlinear solutions $u_1$ and $u_2$ decays sufficiently fast at two different times, it implies that $u_1 \equiv u_2$.

Antigen-specific CD4+T cells in Anaplasma marginale infection of calves
Creators: name: Han, Sushan
Publisher: name: Washington State University
Year: 2074
Subjects: Calves -- Diseases

description: Acquired T-cell immunity is central for protection against intracellular infection. However, the role of antigen-specific T cells in persistent systemic disease is poorly understood. We investigated this with the ruminant bacterium Anaplasma marginale, which replicates to 109 bacteria/ml of blood during acute infection and 106 bacteria/ml throughout persistent anaplasmosis. We established that immunization-specific CD4+ T cell responses were rapidly and permanently lost following challenge. To determine the fate of antigen-specific CD4+ T cells we enumerated specific T cells with DRB3*1101 MHC class II tetramers and FACS. Immunization produced antigen-specific T cell frequencies of 0.025% of CD4+ T cells that rapidly declined near peak bacteremia to 0.0003%. Low frequencies of tetramer+ CD4+ T cells in spleen, liver, and lymph nodes 9-12 weeks post-challenge indicated lack of sustainable antigen-specific responses in these lymphoid compartments. Infection of cattle with A. marginale, therefore, caused rapid, permanent loss of antigen-specific T cells, which may be a strategy of immune modulation for A. marginale. We next examined the role of specific-CD4+ T cells primed by infection by observing serum, PBMC, and spleen for antigen-specific humoral and CD4+ T cell responses during acute and persistent infection of na ve calves. Calves developed high titers of antigen-specific IgG day 9 post-infection, but specific T cells appeared in PBMC day 39 and as late as day 112 post-infection. Responding T cells were predominantly CD4+ T cells that did not produce IFN-[gamma], and responses were transient, disappearing rapidly and reappearing sporadically 8 or less times in one year. Splenocytes developed initial antigen-specific T cell responses days 48 and 89 post-infection, and responses were similarly transiently with no evidence of sequestration during infection. In conclusion, A. marginale-specific CD4+ T cells primed by infection occur in PBMC and spleen during acute and persistent infection well after emergence of high titers of specific IgG, and cells are continuously down regulated similar to immunization-specific T cells, in the face of persistently high level bacteremia.

description: The first color photos of the parametric down-conversion (PDC) emission cone illustrate the correlation of longitudinal- and transverse momentum in the process, i.e., wavelength-dependent emission angle of PDC photons. However, current experiments and applications are more conveniently described in terms of discrete mode sets, with the most suitable choice depending on the propagation symmetries of the experimental setting. Remarkably, despite the fact that experiments with PDC sources are becoming ever more demanding, e.g. in terms of brightness or state fidelity, a description of spectral-spatial coupling in parametric downconversion for the case of discrete modal decompositions remains elusive. We present a comprehensive study, in theory and experiment, of the spectral dependence of the transverse Laguerre-Gauss modes in parametric downconversion. Moreover, we show how the spectral and spatial coupling can be harnessed to tune the purity of the well-known orbital angular momentum entanglement. This work has implications for efficient collection of entangled photons in a transverse single mode, quantum imaging, and engineering pure states for high-dimensional quantum information processing.

description: The practice of gathering and harvesting wild foods has seen renewed interest in recent decades. In addition to contributing to food security and food sovereignty, foraging plays a role in promoting socioecological resilience and creating communities of belonging. However, foraging is generally prohibited by regulations governing public lands in the United States and elsewhere. The growth in food forests suggests public policymakers and land managers’ may be interested in reconsidering this broad prohibition of foraging but require an information base to do so. While a body of research on foraging exists, news media coverage of foraging represents an additional, readily available source of input. As a consequence, framings of foraging in media coverage likely influence managers’ deliberations on this practice. The current paper uses automated content analysis to understand how the practice of gathering and consuming wild foods is framed in print and digital news media, and how these depictions have varied in a 15-year period that includes the Great Recession. Our results show that prevalent framings of foraging represent it variously as a self-provisioning practice or a source of luxury commodities and experiences, with economic uncertainty appearing to affect the frequency of each framing by news media sources. Given managers’ ease of access to them, these distinct framings may influence future regulatory landscapes of foraging.

description: Scaling of mass ratios in intermediate volumes, obtained with improved SU(2) lattice actions is tested against analytic results for the Wilson and continuum action. A new improved action is introduced by adding a 2X2 plaquette to the Symanzik action. Completing a square leads to a covariant propagator that simplifies perturbative calculations. Data is presented on lattices of size 4**3X128, with lattice spacings of approximately 0.02 and 0.12 fermi. For the latter case no further improvement as compared to the tree-level action was observed when including the Lepage-Mackenzie tadpole correction to the one-loop improved Luscher-Weisz Symanzik action.

New advances in nebular photoionisation modelling

description: The study of photoionised gas in planetary nebulae (PNe) has played a major role achieving, over the years, a better understanding of a number of physical processes pertinent to a broader range of fields than just PNe studies, ranging from atomic physics to stellar evolution. Whilst empirical techniques are routinely employed for the analysis of the emission line spectra of such objects, the accurate interpretation of the observational data often requires the solution of the radiative transfer (RT) problem in the nebula, via the application of a photoionisation code.The development of the codes has been driven by the observational constraints available, but also compromised by the available computer power. Modern codes are faster and more flexible, with the ultimate goal being the achievement of a description of the observations relying on the smallest number of parameters possible. In this light, recent developments have been focused on the inclusion of new atomic data, the inclusion of a realistic treatment for dust grains mixed in the ionised and photon dominated regions (PDRs) and the expansion of some codes to PDRs with the inclusion of chemical reaction networks. Furthermore the last few years have seen the development of fully 3D photoionisation codes based on the Monte Carlo method. A review of the photoionisation codes currently in use is given here, with emphasis on recent developments, including the expansion of the models to the 3D domain, the identification of new observational constraints and how these can be used to extract useful information from realistic models.[Abridged]

Deciphering the MHC class I-unrestricted immune response to Rhodocossus equi
Creators: name: Harris, Seth Paul
Publisher: name: Washington State University
Year: 2010
Subjects: Rhodococcus -- Immunological aspects

description: Rhodococcus equi is an important respiratory pathogen of foals which is ubiquitous in the environment. The bacterium survives within the soil, likely infecting foals within the first few weeks of life. Adult horses are naturally immune due to a protective type I immune response. Foals, however, lack the protective type I immune response during the neonatal period rendering them susceptible to disease. Protective immunity to R. equi is characterized by Th1 CD4+ T-lymphocytes and CD8+ cytotoxic T-lymphocytes (CTL). The CD4+ T-lymphocytes are potent producers of IFN-[gamma], which functions to upregulate phagosomal maturation, while the CTL directly lyse R. equi infected macrophages. Recent characterization of the CTL demonstrated several unique features, namely that they are MHC class I-unrestricted, they are present in all adult horses, and they are absent during the neonatal period and develop as the foal ages. The first part of this project demonstrated that the antigens recognized by MHC class I-unrestricted CTL was a non-protein, and was later shown to be R. equi cell wall lipids. The cell wall lipids were composed of three primary lipid fractions: trehalosemonomycolate (TMM), trehalose-dimycolate (TDM), and cardiolipin (CL). MHC mismatched target cells pulsed with purified TMM and CL, but not TDM were lysed by CTL. Furthermore, all three lipids significantly elevated transcription of the cytokine IFN-[gamma], but not IL-4, supporting the role of lipids as immunogens. Future work will focus on whether the lipid antigen is presented by CD1 molecules. The second part of this project evaluated the protective mechanism behind oral inoculation in neonatal foals with live R. equi. Foals orally inoculated with virulent R. equi had accelerated appearance of CTL, which developed by three weeks of age in comparison to uninoculated controls which developed CTL at five weeks. Unexpectedly, foal PBMC produced adult levels of IFN-[gamma] at 1, 3, and 5 weeks when stimulated by R. equi or extracted cell wall lipids. This data supports CTL as being an important component in protective immunity.

description: We investigate dark matter (DM) production in an early matter dominated era where a heavy long-lived particle decays to radiation and DM. In addition to DM annihilation into and thermal DM production from radiation, we include direct DM production from the decay of the long-lived particle. In contrast to earlier treatments the temperature dependence of the number of degrees of freedom $g_*$ in the Standard Model (SM) plasma is treated carefully. Besides the well-known cases of thermal hot and cold DM, additional regions of parameter space with the approximately correct DM relic density appear. In some of these regions the temperature dependence of $g_*$ can change the final DM density by several hundred percent. Furthermore, we analyze the effect of allowing nonvanishing initial abundances for radiation and DM. We find an upper bound on the mass of the long-lived particle if the DM annihilation cross section is below that corresponding to thermal WIMP (Weakly Interactive Massive Particle) DM in standard cosmology.

description: Recently, the studies of topological corner states (TCSs) are extended from crystals to quasicrystals, which are referred to as higher-order topological quasicrystalline insulators (HOTQIs). However, the TCSs of complete quasi-periodic structure in photonic systems have yet to be demonstrated. Moreover, there is only one TCS in each corner region in higher-order topological insulators (HOTIs). Increasing the number of TCS is expected to increase application potential of TCSs. In this work, HOTQIs in photonic systems are experimentally observed. It is found that HOTQIs possess TCS arrays, and each TCS array contains several TCSs. Furthermore, the universal theoretical framework of the multimer analysis method is improved, and the difference in the average charge density is proposed as a real-space topological index. These results will open up new ideas for investigating highly integrated, multi-region localized TCSs and are expected to provide new ways to explore topological phenomena and the applications of photonic quasicrystals.

Abstract
MenACWY-TT (Nimenrix®) is a quadrivalent meningococcal tetanus toxoid conjugate vaccine licensed in Europe for active immunisation of individuals aged ≥6 weeks against invasive disease caused by Neisseria meningitidis capsular groups A, C, W and Y. MenACWY-TT is the first quadrivalent conjugate vaccine to be approved in Europe for use in infants as young as 6 weeks of age. Numerous phase II–IIIb clinical studies showed that intramuscular MenACWY-TT administered as primary or booster vaccination was highly immunogenic for all four vaccine capsular groups and had an acceptable reactogenicity profile in individuals aged 6 weeks to ≥56 years. MenACWY-TT is as immunogenic and safe as other previously licensed monovalent capsular group C or quadrivalent capsular groups A, C, W and Y meningococcal vaccines and can be coadministered with other routine vaccines without adversely affecting the immunogenicity or safety profiles of either vaccine. Current data indicate that primary and booster vaccination with MenACWY-TT is a valuable and safe option for broadening meningococcal protection against four capsular groups across a broad age range, starting as early as 6 weeks of age.

Essays on stock return volatility in bank holding company and trading by company insider and institutional investors
Creators: name: Wu, Dandan
Publisher: name: Washington State University
Year: 2010
Subjects: Insider trading in securities

description: Chapter one, "Insider Trading and Risk Taking in BHCs", documents a significant and positive relation between current and past quarter insider purchases (net demand) and current quarter changes in risk taking for BHCs with lower than average capital ratios over the 1995- 2003 time period. My findings are consistent with the argument that the dramatic increase in the use of equity-based compensation combined with banks' high leverage has had a substantial impact on bank managers' willingness to take risk. Chapter two, "Institutional Investor Demand and Idiosyncratic Volatility: Are Bank Holding Companies Special?" examines the relation between quarterly institutional demand and the previous quarter's change in idiosyncratic volatility. While changes in percentage institutional ownership are inversely related to the previous quarter's changes in idiosyncratic volatility of non-financial stocks in the NYSE/AMEX/Nasdaq common stock universe, they are not significantly related to the previous quarter's changes in idiosyncratic volatility of BHC stocks. I find that the risk-seeking affiliated trust departments of BHCs appear to increase their holdings of parent company stock following an increase in idiosyncratic volatility during the period from 1986 to 1996, thereby offsetting any aversion to the increased risk by other institutions. In addition, institutional investors' overall indifference to risk-taking changes among BHCs is likely also due to the low level of idiosyncratic volatility and few opportunities for informed trading in the banking industry.

description: An important example of a model category is the category of unbounded chain complexes of R-modules, which has as its homotopy category the derived category of the ring R. This example shows that traditional homological algebra is encompassed by Quillen's homotopical algebra. The goal of this paper is to show that more general forms of homological algebra also fit into Quillen's framework. Specifically, a projective class on a complete and cocomplete abelian category A is exactly the information needed to do homological algebra in A. The main result is that, under weak hypotheses, the category of chain complexes of objects of A has a model category structure that reflects the homological algebra of the projective class in the sense that it encodes the Ext groups and more general derived functors. Examples include the "pure derived category" of a ring R, and derived categories capturing relative situations, including the projective class for Hochschild homology and cohomology. We characterize the model structures that are cofibrantly generated, and show that this fails for many interesting examples. Finally, we explain how the category of simplicial objects in a possibly non-abelian category can be equipped with a model category structure reflecting a given projective class, and give examples that include equivariant homotopy theory and bounded below derived categories.

However, experiments indicate that organic polaritons propagate in a diffusive manner and more slowly than their group velocity. Here, we resolve this controversy by means of molecular dynamics simulations of Rhodamine molecules in a Fabry-Pérot cavity. Our results suggest that polariton propagation is limited by the cavity lifetime and appears diffusive due to reversible population transfers between polaritonic states that propagate ballistically at their group velocity, and dark states that are stationary. Furthermore, because long-lived dark states transiently trap the excitation, propagation is observed on timescales beyond the intrinsic polariton lifetime. These insights not only help to better understand and interpret experimental observations, but also pave the way towards rational design of molecule-cavity systems for coherent exciton transport.

description: During the Manchester Blitz my Grandma broke her arm. She was given lots of sympathy and really enjoyed the gifts and good wishes. The truth is that she did hurt her arm but not because of the Blitz hitting Manchester - she actually hurt her arm catching some chickens that got loose on the train when she had been flirting with some soldiers.

description: To elucidate the spin relaxation mechanism of SrNbO3 (SNO) ultrathin films, the transport properties of a series of SNO films with various thicknesses were measured on both sides of the metal insulator transition. The spin orbit scattering time was deduced from the analysis of the magnetoresistance with weak antilocalization theory, and it was found that the spin orbit scattering time was inversely proportional to the momentum scattering time. This result was explained in terms of the D`Yakonov Perel` mechanism, indicative of the dominant Rashba effect. The values of the Rashba parameter were largest in the values reported for other ultrathin films of metallic oxides.

description: The excited states of the proton emitter $^{151}$Lu were reinvestigated in a recoil-decay tagging experiment at the Accelerator Laboratory of the University of Jyväskylä (JYFL). The level scheme built on the ground state of $^{151}$Lu was updated with five new $γ$-ray transitions. Large-scale shell model calculations were carried out to interpret the experimental level scheme. It is found that the excitation energies of states above the $27/2^-$ and $23/2^+$ isomeric levels can be sensitive to excitations from $g_{7/2}$ and $d_{5/2}$ to single-particle orbitals above $N=Z=64$.

Three-Dimensional Ionisation, Dust RT and Chemical Modelling of Planetary Nebulae

description: The assumption of spherical symmetry is not justified for the vast majority of PNe. The interpretation of spatially-resolved observations cannot rely solely on the application of 1D codes, which may yield incorrect abundances determinations resulting in misleading conclusions. The 3D photoionisation code MOCASSIN (Monte CAarlo SimulationS of ionised Nebulae) is designed to remedy these shortcomings. The 3D transfer of both primary and secondary radiation is treated self-consistently without the need of approximations. The code was benchmarked and has been applied to the study of several PNe. The current version includes a fully self-consistent radiative transfer treatment for dust grains mixed within the gas, taking into account the microphysics of dust-gas interactions within the geometry-independent Monte Carlo transfer. The new code provides an excellent tool for the self-consistent analysis of dusty ionised regions showing asymmetries and/or density and chemical inhomogeneities. Work is currently in progress to incorporate the processes that dominate the thermal balance of photo-dissociation regions (PDRs), as well as the formation and destruction processes for all the main molecular species.

description: Economic imperialism remains the dominant paradigm in Political Economy when examining modern empires. The Core-Periphery relationships of World Systems Theory based around exploitation of labor and resources, or capitalist cycles of accumulation is a powerful theoretical tool, and a useful lens through which to view European colonialism. However, the expansion of the Japanese empire into Taiwan did not follow the same pattern of development and exploitation as its European counterparts, and had dramatically different outcomes for the former colonized state. This project compares standard economic analysis of Japanese colonialism with a modified version of Michael Mann s model of social power allowing for ideological drivers of expansion that incorporates the work of John K Fairbank on the Chinese World Order. Specifically attempting to identify the role of Confucianism as a governing ideology in Japanese imperial expansion from 1895 (the treaty of Shimonoseki) to 1937 (the beginning of Japanese militarism).

description: Edward Mellor was born on the 4th of July, 1914. When he was 15, his parents both died. He had two brothers who were in the Army. He was living on the streets and his brothers helped him lie about his age to get into the Army. Because his parents died there was no one to step in and get him out. He was a gunner in the Army and in the early part of the war, he was based on the Isle of Wight. His wife, Trudy, who was my great-grandma, went down to the Isle of Wight with my Aunt Sheila who was then a baby. She did this so that he would see his daughter just in case he didn't make it back.

During this time, the Allied troops had been driven back to Dunkirk and were under fire from the German forces with no means of escape. Ted was on the beach at Dunkirk and was taking his fellow soldiers and putting them on small boats to help them get back to England safely. He stayed longer to try and help more people before coming back. He always said that football saved his life because he played for the England Army team and won a World Cup kind of medal. This meant that he didn't get sent back to Europe as often as he maybe could have after Dunkirk.When he finally came home after the war, he never spoke of the war ever again. The only way we found out was through Trudy. Trudy had two brothers who were in the RAF (Royal Air Force); they were both killed in battle. They were called Joe and George and were buried in military graveyards in Belgium since that was where they died. After the war, Ted wouldn't eat corned beef in the house again as that was all they ate in the war. We couldn't get a picture of Ted because he hated to get in his war uniform. Trudy was moved down to a farm in Bridport in the south regions of England, which is where my grandma, Pat, was born. The farmer's wife couldn't have children and was always taking Pat away and asking if they could buy her. Trudy was frightened that someone would take her so they moved back to Manchester and lived in Moston. Pat can remember hiding in the cellar when the Manchester Blitz happened - such a coincidence that when Pat moved to Manchester, the Germans started bombing. They were bombing Boggart Hole Clough as there was an aircraft factory in New Moston.Ted passed away on the 22nd of April 1985. It was only when he died that people started talking about his work because he wouldn't have let it happen since he hated the Army so much.
Exact master equation and decoherence dynamics of Majorana zero modes under the gate-induced charge fluctuation

description: In this paper, we derive the exact master equation to investigate the decoherence dynamics of Majorana zero modes in the Kitaev model, a 1D $p\,$-wave spinless topological superconducting chain (TSC), that is disturbed by charge fluctuations through gate controls. The exact master equation is derived by extending Feynman-Vernon influence functional approach to fermionic open systems involving pairing excitations. We obtain the exact master equations for the zero-energy bogoliubon in the TSC, and then transfer it into the master equation for Majorana zero modes. Within this exact master equation formalism, we can describe in detail the non-Markovian decoherence dynamics of zero-energy bogolibons as well as the Majorana zero modes under local perturbations. We find that at zero temperature, there is a zero-energy localized bound state which is not the original zero-energy bogoliubon or the original Majorana zero mode but a localized bound state of Majorana zero mode after the charge fluctuation is taken into account. It is this zero-energy localized bound state that protects Majorana zero modes from decoherence, as a long-time non-Markovain memory effect. However, for the environment at finite temperature, the zero-energy localized bound state cannot be formed when Majorana zero modes are locally perturbed, and decoherence is inevitable.

description: Two isolation performance metrics, Inter-Zone Isolation (IZI) and Inter-Program Isolation (IPI), are introduced for evaluating Personal Sound Zone (PSZ) systems. Compared to the commonly-used Acoustic Contrast metric, IZI and IPI are generalized for multichannel audio, and quantify the isolation of sound zones and of audio programs, respectively. The two metrics are shown to be generally non-interchangeable and suitable for different scenarios, such as generating dark zones (IZI) or minimizing audio-on-audio interference (IPI). Furthermore, two examples with free-field simulations are presented and demonstrate the applications of IZI and IPI in evaluating PSZ performance in different rendering modes and PSZ robustness.
