Evaluation of Targeted Selective Inhibitors to Enhance Temozolomide Treatment Sensitivity in Acute Myeloid Leukemia
Creators: Basonbul, Asmaa A.
Publisher: name: University of Alberta Library
Year: 2024

Temozolomide (TMZ) is an alkylating agent with limited activity in acute myeloid leukemia (AML). The DNA repair enzyme O6-methylguanine methyltransferase (MGMT) enhances tumor cell resistance to TMZ. B-cell lymphoma-2 (BCL-2) and mouse double minute 2 homology (MDM2) are proteins involved in AML cell survival and chemotherapeutic resistance. BCL-2 is an antiapoptotic protein that prevents cell apoptosis, and MDM2 is a ubiquitin E3 ligase that mediates p53 degradation. Inhibiting BCL-2 and restoring p53 functions may affect AML treatment.

Venetoclax (VEN) is a small molecule that promotes cell apoptosis through inhibition of the BCL-2 protein. Idasanutlin (IDA) is an MDM2-specific inhibitor that disrupts p53:MDM2 interactions and restores p53 functions. This study established the need to enhance TMZ sensitivity in AML cells with high and low MGMT expression levels by incorporating VEN and IDA into TMZ treatment.

AML human cell lines and blast-containing mononuclear cells were used to evaluate MGMT and target proteins for each inhibitor. Cell viability, cell apoptosis, and DNA damage were assessed with TMZ alone and in combination with a pre-selected inhibitory concentration of 50% (IC50) of a VEN or IDA inhibitor. Further, VEN inhibitor was applied in vivo using mouse model. Leukemic engrafted mice treated with selected TMZ and VEN concentrations, alone and in combination, were evaluated for survival and CD45+ and CD33+ expression in the bone marrow.

In high and low MGMT-expressing AML cell lines, co-incubation of TMZ with VEN at IC50 resulted in a marked enhancement of TMZ sensitivity. In VEN+TMZ treated cell lines, apoptosis was induced and severe DNA damage was observed compared to TMZ alone. AML patient samples were resistant to TMZ alone but became sensitized to TMZ+VEN in combination, including those with high MGMT expression levels. The combination-treated mice had the longest survival among the group; however, by the time of death, no difference was seen in CD45+ cells compared to the single drug or untreated groups.

In high and low MGMT-expressing cells, co-incubation of TMZ with IDA at IC50 did not improve TMZ sensitivity, regardless of p53 status. In both high and low MGMT-expressing cells, there was no evidence of DNA damage in the TMZ+IDA combination groups compared to TMZ alone. AML patient samples were resistant to TMZ alone and highly sensitive to IC50 IDA. IDA did not enhance the TMZ sensitivity, as insignificant cell death was observed in IDA alone and TMZ combination.

VEN enhances TMZ cytotoxicity in high and low MGMT cells by decreasing cell viability, increasing cell apoptosis, and inducing DNA damage. The opposite was observed in IDA and TMZ combination-treated cells. Overall, we found VEN and TMZ combination to be promising to pursue further for clinical trails.

description: Interactions between Dark Matter (DM) and nucleons relevant for direct search experiments can be organised in a model independent manner using a Galiliean invariant, non--relativistic effective field theory (NREFT). Here one expands the interactions in powers of the momentum transfer $\vec{q}$ and DM velocity $\vec{v}$. This approach generates many operators. The potentially most important subleading operators are odd under $T$, and can thus only be present in a theory with $CP$ violating interactions. We consider two such operators, called $\mathcal{O}_{10}$ and $\mathcal{O}_{11}$ in the literature, in simplified models with neutral spin$-0$ mediators; the couplings are chosen such that the coefficient of the leading spin independent (SI) operator, which survives for $\vec{v} \rightarrow 0$, vanishes at tree level. However, it is generically induced at the next order in perturbation theory. We perform a numerical comparison of the number of scattering events between interactions involving the $T-$odd operators and the corresponding loop induced SI contributions. We find that for ''maximal'' $CP$ violation the former can dominate over the latter. However, in two of the three models we consider, an electric dipole moment of the neutron (nEDM) is induced at two--loop order. We find that the experimental bound on the nEDM typically leads to undetectably small rates induced by ${\mathcal O}_{10}$. On the other hand, the model leading to a nonvanishing coefficient of ${\mathcal O}_{11}$ does not induce an nEDM.

description: My grandfather, Stanislaw Jesinski, was born in Przemyśl, Poland, in 1911. As war was about to break out in 1939, he was in Lwów and traveled home to Przemyśl (his train ticket is included). When word was given to flee to France, he made his way south into Romania, headed for Bucharest, where the Polish Embassy was giving out passports to enable travel. He then traveled to Split before heading to France. The Poles were trained at a camp called Coëtquidan.When France surrendered, the Poles headed for ports in France and Spain and made their way to the UK. He was initially based in Biggar, Scotland, then up and down the east coast and, after the creation of the 1st Polish Armoured Division, in Dalkeith and Newbattle.In 1944, he was sent to Europe, where his division was bombed by the Americans, and participated in the closing of the Falaise Gap. On one end of the gap were the Poles and the Canadians (this is where he got the three pen knives) and on the other end, the Americans. He was injured at Falaise but returned to aid in the march up the coast through Belgium, the Netherlands, and into Germany.After the war, he became an alien until the future of the Poles was decided. They were allowed to stay in the UK and Commonwealth countries, and he remained in Scotland, where he changed his name to Stanley Kean and married.

description: The aorta is the largest artery in the human body. Its origin is the aortic orifice of the aortic valve and ends at the level of the fourth lumbar vertebra. The main function of the aorta is to transport oxygenated blood to supply all organs and cells. With age, structure and therefore function undergo progressive changes. Various changes in aortic morphology include aortic lumen diameter, entire aortic length, thickness, and changes in microstructural components including collagen, elastin, and smooth muscle cells. In addition, the size of all aortic segments increases with age in both sexes. Because age is a major risk factor for degenerative changes and diseases affecting the aorta, understanding the detailed anatomy of the aorta can provide important information about age-related processes in the aorta. Knowledge of the morphological changes in the aorta is also important for future clinical treatments of aortic diseases. Additionally, information about structural changes with age can be used to determine age. This review provides an overview of aortic anatomy, age-related changes in aortic morphology, and aortic diseases.
Evaluating Search Spaces for Programmatic Policies in POMDPs
Creators: Carvalho, Tales Henrique
Publisher: name: University of Alberta Library
Year: 2024

Searching for programmatic policies to solve a reinforcement learning problem can be challenging, particularly when dealing with domain-specific languages (DSLs) that define policies with internal states for partially observable Markov decision processes (POMDPs). This is because they lead to complex and discontinuous search spaces, often requiring combinatorial search processes. To avoid searching in the programmatic space, the recent work LEAPS and HPRL learn latent spaces of DSLs, which are used to define policies for POMDPs. Aside from reconstructing programs from their embedding representations, these spaces are trained to achieve locality in program behavior, expecting that vectors close in the latent space decode to programs that behave similarly. In this work, we show that searching using a hill-climbing process in the original programmatic space, induced by the DSL itself and requiring no learning, achieves a similar locality measure in program behavior and significantly outperforms LEAPS and HPRL in finding high-reward policies. We further analyze the optimization topology induced by the neighborhood function of each search space in conjunction with the reward function of the POMDP. We show that a local search algorithm is more likely to stop in local maxima regions when searching for high-reward policies in the latent space than when searching in the original programmatic space. This result implies that the programmatic space is more conducive to local search and explains its superior performance.
Artificial Gauge Fields in Ultracold Atomic Ensembles
Creators: Cooke, Logan
Publisher: name: University of Alberta Library
Year: 2024

Gauge theory provides a simple and robust way in which to describe the underlying symmetries of nature, and the ability to empirically test such theories is of vital importance. Quantum simulators have found an important application in recent decades, in the generation of artificial gauge fields. These systems allow researchers to create various fields which would otherwise only exist in the most exotic systems. In this thesis, we will discuss techniques with which to realize various artificial gauge fields in spinor Bose-Einstein condensates (BECs), which are coherently manipulated by external radiation. We derive the affect of radio-frequency (RF) and laser fields on atomic spins in a BEC, and then later describe how they may be used to generate both Abelian and non-Abelian gauge fields. We discuss techniques for many-body numerical simulation of BECs in the presence of artificial magnetic fields, created through laser dressing, and extend the algorithm to run more efficiently on a graphics processing unit (GPU). Next, we present a technique for using Floquet engineered RF fields to produce degeneracies in an otherwise nondegenerate spin system; consequently, geometric phases arise which are well described by the presence of a non-Abelian gauge field. We also discuss the relevance of this technique to holonomic quantum computing (HQC). Altogether, we present several theoretical, numerical, and experimental procedures with which researchers may explore both Abelian and non-Abelian gauge theories in ultracold atomic systems.

These include the translation groupoids associated to finite-dimensional linear representations of the circle and real and unitary representations of the real $2\times 2$ orthogonal group. In the case of translation groupoids associated to linear symplectic quotients of representations of a arbitrary compact Lie group $G$, we show that unlike the other cases, the $Γ$-Euler characteristic depends only on the group and not on the representation.

Ichnology and geochemistry: an integrated approach to early marine diagenesis in the Arabian Gulf
Creators: Brown, Drew
Publisher: name: University of Alberta Library
Year: 2024

Neoichnological studies in carbonate-dominated tropical latitudes are sparse. Moreso, the coupling of diagenetic research utilizing ichnology has been largely limited to ancient successions. This thesis combines geochemical analyses with modern ichnological observations to better understand the early marine formation of firmgrounds and hardgrounds in the Abu Dhabi coastal sabkha. First, characterization of infaunal behavior and animal spatial variability help determine study sites of interest within an intertidal zone (Al Qantur lagoon). There exists a relatively low complexity and diversity of burrowing morphologies in Abu Dhabi as attributed to heightened environmental stressors, such as salinity, heat, and subaerial exposure, as well as upward seepage of saline continental brines. Porewater analyses indicate a stabilization of salinity within burrows, suggesting the infauna irrigate their burrows to cope with increasing salinity. Crustacean burrows enhance solute advection in the lower intertidal zone by increasing substrate permeability, facilitating the penetration of seawaters to greater depths. Additionally, our research demonstrates that some examples of firmground and hardground features develop in the subsurface, which challenges traditional interpretations of hardground formation as cemented, exposed seafloors. Here, we present spatially-resolved geochemical analyses to better understand the underlying mechanisms promoting the formation, and resulting diagenetic processes, surrounding firmgrounds and hardgrounds in the Abu Dhabi coastal sabkha. Firmgrounds and hardgrounds both originate through early marine cementation, and microbial sediment cohesion. However, their compositions differ, with firmgrounds predominantly composed of peloids, and hardgrounds characterized by foraminifera and mollusc shells. Hardgrounds display dissolution textures, while firmgrounds remain less affected. Dissolution in Al Qantur lagoon is primarily driven by the advection of continental brines in the upper intertidal zone. Additionally, bioturbation plays a significant role in altering water and sediment chemistry, as crustacean activity spatially influences solute distributions, and prevents cementation. The formation of firmgrounds and hardgrounds depends on a complex hydrological regime that transports solutes via marine and groundwater sources.

Pex13 and Pex14 Regulate Lipid Storage as Class II Lipid Droplet Proteins
Creators: Ueda, Kazuki
Publisher: name: University of Alberta Library
Year: 2024

The compartmentalization of a cell interior into organelles allowed specialized biochemical functions to take place within. The crosstalk between organelles by exchanging metabolites is essential to properly carrying out their functions. One such organelle is peroxisome which specializes in the processing of various lipids and detoxification of reactive oxygen species. Another organelle known as the lipid droplet is responsible for the storage of excess fatty acids. The intimate interaction between the two organelles has been described by the formation of physical contacts and the sharing of biogenesis sites. However, how peroxisomes and lipid droplets coordinate lipid metabolism is incompletely understood.

Previous work in Simmonds lab found noncanonical function and localization of core peroxisome membrane proteins, Pex13 and Pex14, at the lipid droplet. The two Pex proteins normally inserted in the bilayer of the peroxisome membrane are instead localized to the monolayer of the lipid droplet under excess oleic acid supplementation. Therefore, I investigated the mechanism behind the trafficking and retention of Pex13 and Pex14 at the lipid droplet surface in Drosophila melanogaster.

I found that the localization of Pex13 and Pex14 to the lipid droplet in S2 cells supplemented with excess oleate was enhanced by disrupting their trafficking pathway to peroxisomes. The overexpression of various truncation mutants identified that the region predicted to form amphipathic helices is essential for a successful localization of both Pex proteins to the lipid droplet. The analysis of the subcellular localization in peroxisome-deficient Pex19 KO cells revealed that endogenous Pex14 at the lipid droplet is not associated with mitochondria or the endoplasmic reticulum. The trafficking of Pex14 was not affected by the knockdown of Rab1 or Tango1 gene expression required for the translocation of Class I lipid droplet proteins from the endoplasmic reticulum. In addition, the overexpression of Pex13 or Pex14 affected the function of another lipase, Doppelganger von brummer, in a peroxisome-independent manner. The screen of Pex genes in the larval fat body revealed a unique physiological function of Pex13 and Pex14 in tolerance against increased dietary lipids.

Overall, I have identified previously undefined mechanisms behind Pex13 and Pex14 trafficking and localization to the lipid droplet. The direct association of two Pex proteins to the monolayer membrane provides an additional means to regulate lipase activities at the lipid droplet surface.
Role of Cytochrome P450 Enzymes in Inflammation-induced Cardiac Hypertrophy
Creators: ElKhatib, Mohammed
Publisher: name: University of Alberta Library
Year: 2024

Heart failure (HF) is typically preceded by cardiac hypertrophy (CH), which is characterized by cardiomyocytic enlargement following stress. During CH development, expression of cytochrome P450 enzymes (CYPs) and metabolism of arachidonic acid (AA) are altered. Cardiac CYPs metabolize AA into multiple biologically active eicosanoids, that are classified into hydroxyeicosatetraenoic acids (HETEs) and epoxyeicosatrienoic acids (EETs). HETEs are further classified as terminal, subterminal, and mid-chain HETEs. Mid-chain HETEs are a distinct group of CYP1B1-derived eicosanoids that show cardiotoxic hypertrophic properties. Inflammation is involved in CH pathophysiology, but mechanisms of inflammation-induced CH and alteration of CYP-mediated AA metabolism remain elusive. Comprehending the mechanisms of inflammation-induced CH would be invaluable in identifying the molecular entities that should be targeted for pharmacological interventions. Therefore, the objectives of the present work were to investigate the impacts of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and lipopolysaccharide (LPS) on the development of cellular hypertrophy (CeH), expression of CYP1B1, and CYP1B1-mediated AA metabolism, as well as the role of CYP1B1 in TNF-α, IL-6, and LPS -induced CeH in vitro. Our results show that TNF-α, IL-6, and LPS induce mRNA expression of hypertrophic markers, significantly increase cell surface area, induce CYP1B1 at mRNA, protein, and activity levels, and enantioselectively modulate CYP-mediated AA metabolism in favor of cardiotoxic mid-chain HETEs. These effects are ameliorated in the presence of CYP1B1-siRNA or trans-resveratrol. In conclusion, our results demonstrate the crucial role of CYP1B1 in TNF-α, IL-6, and LPS -induced CeH and highlight CYP1B1 as a clear target for potential therapeutic interventions for the prevention and treatment of CeH.

description: Context. Two protoplanets have recently been discovered within the PDS 70 protoplanetary disk. JWST/NIRCam offers a unique opportunity to characterize them and their birth environment at wavelengths difficult to access from the ground. Aims. We aim to image the circumstellar environment of PDS 70 at 1.87 $μ$m and 4.83 $μ$m, assess the presence of Pa-$α$ emission due to accretion onto the protoplanets, and probe any IR excess indicative of heated circumplanetary material. Methods. We obtain non-coronagraphic JWST/NIRCam images of PDS 70 within the MINDS (MIRI mid-INfrared Disk Survey) program. We leverage the Vortex Image Processing (VIP) package for data reduction, and develop dedicated routines for optimal stellar PSF subtraction, unbiased imaging of the disk, and protoplanet flux measurement in this type of dataset. A radiative transfer model of the disk is used to disentangle the contributions from the disk and the protoplanets. Results. We re-detect both protoplanets and identify extended emission after subtracting a disk model, including a large-scale spiral-like feature. We interpret its signal in the direct vicinity of planet c as tracing the accretion stream feeding its circumplanetary disk, while the outer part of the feature may rather reflect asymmetric illumination of the outer disk. We also report a bright signal consistent with a previously proposed protoplanet candidate enshrouded in dust, near the 1:2:4 mean-motion resonance with planets b and c. The 1.87 $μ$m flux of planet b is consistent with atmospheric model predictions, but not that of planet c. We discuss potential origins for this discrepancy, including significant Pa-$α$ line emission. The 4.83 $μ$m fluxes of planets b and c suggest enshrouding dust or heated CO emission from their circumplanetary environment.

description: The demand for stereo images increases as manufacturers launch more XR devices. To meet this demand, we introduce StereoDiffusion, a method that, unlike traditional inpainting pipelines, is trainning free, remarkably straightforward to use, and it seamlessly integrates into the original Stable Diffusion model. Our method modifies the latent variable to provide an end-to-end, lightweight capability for fast generation of stereo image pairs, without the need for fine-tuning model weights or any post-processing of images. Using the original input to generate a left image and estimate a disparity map for it, we generate the latent vector for the right image through Stereo Pixel Shift operations, complemented by Symmetric Pixel Shift Masking Denoise and Self-Attention Layers Modification methods to align the right-side image with the left-side image. Moreover, our proposed method maintains a high standard of image quality throughout the stereo generation process, achieving state-of-the-art scores in various quantitative evaluations.

Beyond mountain pine beetle: soil carbon storage a decade after tree mortality and the possible influence of soil fungi
Creators: Lau, Nicole
Publisher: name: University of Alberta Library
Year: 2024

Mountain pine beetle (MPB; Dendroctonus ponderosae) disturbances, amplified by climate change, have led to extensive tree mortality and ecosystem succession in boreal forests across western Canada. Often following attack, former ectomycorrhizal (EM) pine stands in Alberta are replaced by arbuscular (AM) mycorrhizal shrubs and forbs. There has been growing interest in the varying ways that EM versus AM fungi influence critical soil processes, particularly concerning carbon cycling. While our comprehension of the specific impacts that MPB-induced mycorrhizal community succession has on long-term soil carbon storage remains somewhat limited, emerging frameworks offer broad yet valuable initial insights into this complex dynamic. Specifically, given the functional differences between mycorrhizal fungal types, a shift from EM- to AM-dominance in affected stands may promote soil organic matter formation and carbon stabilization, potentially enhancing soil carbon stores. The objective of this study was to address the following questions: 1) Will the dominant mycorrhizal type change with disturbance? 2) Does extensive tree mortality change the amount of carbon and nitrogen stored in forest floors and mineral soils? I sampled soil and conducted vegetation surveys at 80 lodgepole pine-dominated sites across west-central Alberta, split by disturbance severity (forests with >70% lodgepole pine basal area killed by MPB versus intact forest) and soil texture (coarse versus fine). I used density fractionation to separate soils into mineral-associated organic matter (MAOM) and particulate organic matter (POM) pools. I explored whether disturbance, mycorrhizal type, soil texture, and sampling depth affected carbon and nitrogen concentrations in these pools. There was a pronounced shift in mycorrhizal community composition from EM to AM dominance following MPB- induced forest transformations. However, overall carbon and nitrogen concentrations in bulk mineral soil, and carbon and nitrogen stocks in forest floors, remained largely unaffected. In addition, I confirmed that carbon and nitrogen storage are strongly dependent on soil texture and depth. Though there were no changes in soil carbon concentrations in the bulk soil, carbon in the MAOM fraction was relatively higher in the disturbed than intact sites. Greater carbon and nitrogen allocation into the MAOM pools is consistent with emerging hypotheses on the importance of AM vegetation to long-term carbon storage in soils. Taken together, these patterns in carbon storage may point to the resiliency of these soils, supported by soil organic matter interactions with the mineral matrix and potentially the buffering effects from the increase of AM fungi and their unique nutrient dynamics. The findings from this study may enhance our understanding of soil processes, offering opportunities to optimize soil carbon stocks and ecosystem services in recovering boreal forests.

Control of D-Spacing and Graphitic Defects in Asphaltene-Derived Hard Carbons for Energy Storage

With the increasing demand for energy storage and declining lithium stores around the globe, sodium is emerging as an alternative source due to its natural abundance and similar reaction kinetics and chemical properties to lithium. While sodium-ion and lithium-ion batteries started development at approximately the same time, sodium-ion batteries were cast aside as sodium has a larger ionic radius, leading to incompatibilities with graphite and its interlayer spacing. Asphaltenes are the heaviest components, with a relatively high percentage commonly found in the Alberta Oilsands bitumen. They are currently being explored for their purposes in energy storage as they can form hard carbons after treatment. Asphaltenes are the portion of materials in oil soluble in toluene and insoluble in excess n-heptane. These carbons are an excellent choice for sodium-ion batteries as they have large interlayer spacing, lattice defects, and disorder, which can better accommodate the size of sodium ions. This thesis explores the various treatment conditions used to tailor the interlayer spacing and graphitic defects of asphaltene-derived hard carbons to better accommodate the intercalation of sodium ions during charge/discharge processes for future applications. Conventional graphite has a d-spacing of 0.336 nm, and the results from these experiments have resulted in an extensive range of interlayer spacing ranging from a low of 0.373 nm to a high of 0.392 nm. This increase was accomplished by altering the hold temperature, hold time, and heating rate for the stabilization/oxidation and carbonization processes of asphaltenes to convert them into usable materials for energy storage. The increase in interlayer spacing seen from these results allows for the potential usage of Alberta asphaltenes in sodium-ion batteries.

Liquidity Management Attacks on Decentralized Lending Markets

Decentralized Finance (DeFi) continues to open up promising opportunities for a broad spectrum of users, with lending pools emerging as a cornerstone of its applications. While prominent platforms like Compound and Aave maintain a large share of the funds in lending pools, numerous other smaller pools also exist. Many of these smaller entities draw heavily from the design principles of their larger counterparts due to the complex nature of lending pool design.

This thesis asserts that the design approaches that serve larger pools effectively may not necessarily be the most beneficial for smaller lending pools. We identify and elaborate on two liquidity management attacks, which can allow well-funded attackers to exploit specific circumstances within lending pools for personal gain. Although large lending pools, due to their vast and diverse liquidity and high user engagement, are generally less vulnerable to these attacks, smaller lending protocols may need to employ specialized defensive strategies, particularly during periods of low liquidity. We also show that beyond the six leading lending protocols, there exists a market value exceeding \\$1.75 billion. This considerable sum is dispersed among over 200 liquidity pools, posing a potentially attractive target for malicious actors.

Furthermore, we evaluate existing designs of lending pools and suggest a novel architecture that distinctly separates the liquidity and logic layers. This unique setup gives smaller pools the adaptability they need to link with larger, well-established pools. Despite encountering certain constraints, these emerging pools can leverage the considerable liquidity from larger pools until they generate sufficient funds to form their own standalone liquidity pools. This design cultivates a setting where multiple lending pools can integrate their liquidity components, thus encouraging a more diverse and robust liquidity environment.

description: Low Earth orbit (LEO) satellites and reconfigurable intelligent surfaces (RISs) have recently drawn significant attention as two transformative technologies, and the synergy between them emerges as a promising paradigm for providing cross-environment communication and positioning services. This paper investigates an integrated terrestrial and non-terrestrial wireless network that leverages LEO satellites and RISs to achieve simultaneous tracking of the three-dimensional (3D) position, 3D velocity, and 3D orientation of user equipment (UE). To address inherent challenges including nonlinear observation function, constrained UE state, and unknown observation statistics, we develop a Riemannian manifold-based unscented Kalman filter (UKF) method. This method propagates statistics over nonlinear functions using generated sigma points and maintains state constraints through projection onto the defined manifold space. Additionally, by employing Fisher information matrices (FIMs) of the sigma points, a belief assignment principle is proposed to approximate the unknown observation covariance matrix, thereby ensuring accurate measurement updates in the UKF procedure. Numerical results demonstrate a substantial enhancement in tracking accuracy facilitated by RIS integration, despite urban signal reception challenges from LEO satellites. In addition, extensive simulations underscore the superior performance of the proposed tracking method and FIM-based belief assignment over the adopted benchmarks. Furthermore, the robustness of the proposed UKF is verified across various uncertainty levels.

description: Linear colliders rely on high-quality flat beams to achieve the desired event rate, while avoiding potentially deleterious beamstrahlung effects. Here, we show that flat beams in plasma accelerators can be subject to quality degradation due to emittance mixing. This effect occurs when the beam particles' betatron oscillations in a nonlinearly coupled wakefield become resonant in the horizontal and vertical planes. Emittance mixing can lead to a substantial decrease of the luminosity, the main quantity determining the event rate. In some cases, the use of laser drivers or flat particle beam drivers may decrease the fraction of resonant particles and, hence, mitigate emittance deterioration.

title: Effects of Extraversion and Gender on Self-Disclosure of Emotion with a Same-Sex Friend
Creators: name: Ulmen, Patrick M.
Publisher: name: Old Dominion University
Year: 1991

description: The study examined subjects' perceptions about disclosure of emotion by a stimulus person who was depicted as extraverted or introverted, and subjects' self-disclosure of emotion based on their own level of extraversion. In addition, the role of gender in disclosure of emotion was examined. The findings on differences in disclosure of emotion based on gender are considered tentative. Males self-disclosed anger more to same-sex stimulus persons than did females, but this was the only significant difference. An introverted compared to an extraverted stimulus person was found to elicit more disclosure about emotions associated with calmness and depression. Emotions which an introverted stimulus person is perceived to disclose are depression, calmness, anxiety, and apathy. An extraverted stimulus person is perceived as being more likely to disclose happiness. The roles of predictability, understanding, and friendliness in self-disclosure of emotion is discussed.

description: We use entanglement witnesses related to the entanglement negativity of the state to detect entanglement in the $XY$ chain in the postquench states in the thermodynamic limit after a quench when the parameters of the Hamiltonian are changed suddenly. The entanglement negativity is related to correlations, which in the postquench stationary state are described by a generalized Gibbs ensemble, in the ideal case. If, however, integrability breaking perturbations are present, the system is expected to thermalize. Here we compare the nearest-neighbor entanglement in the two circumstances.
