description: We present ALMA observations of the continuum and line emission of $^{12}$CO, $^{13}$CO, C$^{18}$O, and [C I] for a portion of the G287.38-0.62 (Car 1-E) region in the Carina star-forming complex. The new data record how a molecular cloud responds on subarcsecond scales when subjected to a powerful radiation front, and provide insights into the overall process of star formation within regions that contain the most massive young stars. The maps show several molecular clouds superpose upon the line of sight, including a portion of the Western Wall, a highly-irradiated cloud situated near the young star cluster Trumpler 14. In agreement with theory, there is a clear progression from fluoresced H$_2$, to [C I], to C$^{18}$O with distance into the PDR front. Emission from optically thick $^{12}$CO extends across the region, while $^{13}$CO, [C I] and especially C$^{18}$O are more optically thin, and concentrate into clumps and filaments closer to the PDR interface. Within the Western Wall cloud itself we identify 254 distinct core-sized clumps in our datacube of C$^{18}$O. The mass distribution of these objects is similar to that of the stellar IMF. Aside from a large-scale velocity gradient, the clump radial velocities lack any spatial coherence size. There is no direct evidence for triggering of star formation in the Western Wall in that its C$^{18}$O clumps and continuum cores appear starless, with no pillars present. However, the densest portion of the cloud lies closest to the PDR, and the C$^{18}$O emission is flattened along the radiation front.

description: During the shock-wave propagation in a core-collapse supernova (SN), matter turbulence may affect neutrino flavor conversion probabilities. Such effects have been usually studied by adding parametrized small-scale random fluctuations (with arbitrary amplitude) on top of coarse, spherically symmetric matter density profiles. Recently, however, two-dimensional (2D) SN models have reached a space resolution high enough to directly trace anisotropic density profiles, down to scales smaller than the typical neutrino oscillation length. In this context, we analyze the statistical properties of a large set of SN matter density profiles obtained in a high-resolution 2D simulation, focusing on a post-bounce time (2 s) suited to study shock-wave effects on neutrino propagation on scales as small as O(100) km and possibly below. We clearly find the imprint of a broken (Kolmogorov-Kraichnan) power-law structure, as generically expected in 2D turbulence spectra. We then compute the flavor evolution of SN neutrinos along representative realizations of the turbulent matter density profiles, and observe no or modest damping of the neutrino crossing probabilities on their way through the shock wave. In order to check the effect of possibly unresolved fluctuations at scales below O(100) km, we also apply a randomization procedure anchored to the power spectrum calculated from the simulation, and find consistent results within \pm 1 sigma fluctuations. These results show the importance of anchoring turbulence effects on SN neutrinos to realistic, fine-grained SN models.

description: The last two decades are marked by a renaissance in hadronic spectroscopy caused by the arrival of vast experimental information on exotic states in the spectrum of charmonium and bottomonium. Most of such states have properties at odds with the predictions of the quark model and reside very close to strong hadronic thresholds. Prominent examples are provided by the glorious $X(3872)$ charmonium-like state and the doubly charmed tetraquark $T_{cc}^+$ with the masses within less than 1 MeV from the $D\bar{D}^*$ and $DD^*$ open-charm thresholds, respectively. The universality of this feature hints towards the existence of a general pattern for such exotic states. In this work we discuss a possible generic mechanism for the formation of near-threshold molecular states as a result of the strong coupling of compact quark states with a hadronic continuum channel. The compact states that survive the strong coupling limit decouple from the continuum channel and therefore also from the formed hadronic molecule - if realised this scenario would provide a justification to treat hadronic molecules isolated, ignoring the possible influence from surrounding, compact quark-model states. We confront the phenomenology of the $D_{s1}(2460)$ and $D_{s1}(2536)$ with this picture and find consistency, although other explanations remain possible for those states.

description: Quantum magnetism is a fundamental phenomenon of nature. As of late, it has garnered a lot of interest because experiments with ultracold atomic gases in optical lattices could be used as a simulator for phenomena of magnetic systems. A paradigmatic example is the time evolution of a domain-wall state of a spin-1/2 Heisenberg chain, the so-called domain-wall melting. The model can be implemented by having two species of bosonic atoms with unity filling and strong on-site repulsion U in an optical lattice. In this paper, we study the domain-wall melting in such a setup on the basis of the time-dependent density matrix renormalization group (tDMRG). We are particularly interested in the effects of defects that originate from an imperfect preparation of the initial state. Typical defects are holes (empty sites) and flipped spins. We show that the dominating effects of holes on observables like the spatially resolved magnetization can be taken account of by a linear combination of spatially shifted observables from the clean case. For sufficiently large U, further effects due to holes become negligible. In contrast, the effects of spin flips are more severe as their dynamics occur on the same time scale as that of the domain-wall melting itself. It is hence advisable to avoid preparation schemes that are based on spin-flips.

description: Magnetic Particle Imaging hardware has reached human scale and thus patient safety questions and clinical application scenarios are in the focus of current research. In this work, we present a safe real-time 3D MPI system for cerebral applications. High voltages are avoided to ensure patient safety by a low voltage-high current transmit coil design. The developed 2D drive-field generator generates a field-free-point trajectory in the sagittal xz-plane that is shifted by a dynamic selection-field sequence along the y-axis. The scanner generates 3D images with 4 frames/second and allows for direct visualization of the clinically preferred transversal yz-plane, which is crucial for future brain examinations. Advanced reconstruction techniques reach a system sensitivity of 4 μgFe with respect to the iron mass in a sensitivity study.

New Fast and Accurate Steady-State Analysis Approach for Design, Optimization, and Simulation of General Power Converter Systems
Creators: Sadri, Reza
Publisher: name: University of Alberta Library
Year: 2023

Accurate steady-state analysis of power converters are essential for converter design and optimization. Steady-state responses are also useful for component selection, loss calculation, identification of soft switching operation, and small signal modeling of power converters. Normally, a brute-force simulation is carried out to achieve the steady-state response; however, due to the zero initial conditions assumption, the simulation time in such methods is not efficient and fast. An accurate steady-state response, however, can be obtained if the initial conditions at the beginning of a switching cycle of the converter are accurately known. In this thesis, a non-iterative improved Laplace based theorem and enhanced state vector algorithm are proposed to calculate the steady-state initial conditions of the power converters.

The proposed methods use the system’s switching time and state space representation to calculate the system’s initial vector. However, assuming the switching times as known inputs is not valid for all types of converters, such as the case of converters with uncontrolled switches or converters operating in discontinuous conduction mode. The proposed method is further modified to address this challenge by using the bisection approach to find the switching time of the converters that feature a monotonic function of the switching time. Then, a Switching Time Estimator (STE) is proposed to remove the monotonic function limitation on the type of converters since it uses a general-purpose simulator to find the uncontrolled events’ switching time.

The thesis also discusses the extension of the proposed approaches to AC-DC and DC-AC converters, which are more challenging as multiple frequencies and variable amplitudes are involved. These challenges are overcome by modifying the period that the method will be applied and using a piecewise linear approximation of AC sources. Furthermore, the thesis discusses the steady-state analysis of the closed loop power converters. To calculate the initial vector of closed loop systems, the proposed Switching Time Estimator (STE) is modified to update the state of the controller.

Several examples are provided in each chapter to demonstrate the speed of the proposed method compared to the existing approaches. In addition, the proposed method uses the calculated initial vector to achieve the steady-state waveforms of each converter, which are then compared to the Power Simulation (PSIM) generated waveforms to show the accuracy of the proposed method.

description: Anomalous hydrodynamics is a low-energy effective theory that captures effects of quantum anomalies. We develop a numerical code of anomalous hydrodynamics and apply it to dynamics of heavy-ion collisions, where anomalous transports are expected to occur. This is the first attempt to perform fully non-linear numerical simulations of anomalous hydrodynamics. We discuss implications of the simulations for possible experimental observations of anomalous transport effects. From analyses of the charge-dependent elliptic flow parameters ($v_2^\pm$) as a function of the net charge asymmetry $A_\pm$, we find that the linear dependence of $Δv_2^\pm \equiv v_2^- - v_2^+$ on the net charge asymmetry $A_\pm$ cannot be regarded as a robust signal of anomalous transports, contrary to previous studies. We, however, find that the intercept $Δv_2^\pm(A_\pm=0)$ is sensitive to anomalous transport effects.

description: We generalize the quasi-diabatic (QD) propagation scheme to simulate the non-adiabatic polariton dynamics in molecule-cavity hybrid systems. The adiabatic-Fock states, which are the tensor product states of the adiabatic electronic states of the molecule and photon Fock states, are used as the locally well-defined diabatic states for the dynamics propagation. These locally well-defined diabatic states allow using any diabatic quantum dynamics methods for dynamics propagation, and the definition of these states will be updated at every nuclear time step. We use several recently developed non-adiabatic mapping approaches as the diabatic dynamics methods to simulate polariton quantum dynamics in a Shin-Metiu model coupled to an optical cavity. The results obtained from the mapping approaches provide very accurate population dynamics compared to the numerically exact method and outperform the widely used mixed quantum-classical approaches, such as the Ehrenfest dynamics and the fewest switches surface hopping approach. We envision that the generalized QD scheme developed in this work will provide a powerful tool to perform the non-adiabatic polariton simulations by allowing a direct interface between the diabatic dynamics methods and ab initio polariton information.

description: The Hubbard model in $D$ dimensions, with the on-site repulsion $U$ and the transfer integral between nearest neighbors $-t/\sqrt{D}$, is studied on the basis of the Kondo-lattice theory. If $U/|t| \gg 1$, $|n - 1| \lesssim |t|/(DU)$, where $n$ is the number of electrons per unit cell, and $D$ is so small that $|J|/D \gg k_{\rm B}T_c$, where $J = -4t^2/U$ and $T_c$ is $0 {\rm K}$ for $D = 1$ and is the highest critical temperature among possible ones for $D \ge 2$, a low-$T$ phase where $T_c < T \ll |J|/(k_{\rm B}D)$ is a frustrated electron liquid. Since the liquid is stabilized by the Kondo effect in conjunction with the resonating-valence-bond (RVB) mechanism, it is simply the RVB electron liquid; in one dimension, it is also the Tomonaga-Luttinger liquid. The Kondo energy of the RVB liquid is $k_{\rm B}T_{\rm K} = O(|J|/D)$; its effective Fermi energy is $O(k_{\rm B}T_{\rm K})$. A midband appears on the chemical potential between the upper and lower Hubbard bands; the Hubbard gap is a pseudogap. As regards the density of states per unit cell of the midband, its bandwidth is $O(k_{\rm B}T_{\rm K})$ or $O(|J|/D)$, its peak height is $O(1/U)$, and its spectral weight is $O[t^2/(DU^2)]$. Since the midband almost disappears in the Heisenberg limit, the RVB electron liquid in the Heisenberg limit is simply the RVB spin liquid. The RVB electron and spin liquids adiabatically continue to each other. Since local moments form in a high-$T$ phase where $T \gtrsim T_{\rm K}$, the high-$T$ phase is simply the Mott insulator.

description: Explaining baryon asymmetry, dark matter and inflation are important elements of a successful theory that extends beyond the Standard Model of particle physics. In this paper we explore these issues within the Next-to-Minimal Supersymmetric Standard Model (NMSSM), by studying the conditions for a strongly first order electroweak phase transition, the abundance of the lightest supersymmetric particle (LSP), and inflation driven by a gauge invariant flat direction of MSSM made up of right handed squarks. We present the regions of parameter space which can yield successful predictions for cosmic microwave background (CMB) radiation, the observed relic density for the neutralino LSP, and successful baryogenesis constrained by collider measurements, such as the recent Higgs mass bound, branching ratios of rare, flavour violating decays, and the invisible Z decay width. We also explore where dark matter interactions with xenon nuclei would fall within current bounds of XENON100 and the projected limits for the XENON1T and LUX experiments.

description: Magnetic particle imaging (MPI) is an emerging non-invasive molecular imaging method that can image the concentration and position of superparamagnetic iron oxide (SPIO) nanoparticles. However, the scalability of magnetic particle imaging (MPI) is the major barrier to its clinical use now. For a human bore size of MPI, it is important to achieve a high magnetic gradient for high image resolution with a large enough field-of-view (FOV) for most of body part. In this paper, we present a human-scale amplitude modulation (AM) MPI system with a bore size (200 mm) and using a superconductor that generated a high MPI magnetic gradient of up to 2.5 T/m/µ0 and a 1D-FOV of 100 mm (with a feasible 3D FOV of 140 × 140 × 100 mm). The results of this paper show that the promise of MPI for human application is not far away.

Program Synthesis with Best-First Bottom-Up Search
Creators: Ameen, Saqib
Publisher: name: University of Alberta Library
Year: 2023

Cost-guided bottom-up search (BUS) algorithms use a cost function to guide the search for solving program synthesis tasks. In this thesis, we show that current state-of-the-art cost-guided BUS algorithms suffer from a common problem: they can lose useful information given by the model and fail to perform the search in a best-first order according to the cost function. We introduce a novel best-first bottom-up search algorithm, which we call Bee Search, that does not suffer from information loss and is able to perform cost-guided bottom-up synthesis in a best-first manner. Importantly, Bee Search performs best-first search with respect to the generation of programs, i.e., it does not even create programs that are more expensive than the solution program. It attains best-first ordering with respect to generation by performing a search in an abstract space of program costs. We also introduce a new cost function that better utilizes the information provided by an existing cost model. Empirical results on string manipulation and bit-vector tasks show that Bee Search can outperform the state-of-the-art cost-guided BUS approaches when employing more complex domain-specific languages (DSLs); Bee Search and previous approaches perform equally well with simpler DSLs. Further, our new cost function with Bee Search outperforms previous cost functions on string manipulation tasks.

A Multi-Method Investigation of Educational Activities for Hospital-Based Healthcare Providers During the Covid-19 Pandemic
Creators: Clelland, Ashley D.
Publisher: name: University of Alberta Library
Year: 2023

The Covid-19 pandemic was a period of intense stress for hospital-based healthcare providers (HCPs). Education was frequently proposed as a solution to support HCPs with pandemic-related distress, but little is known about what pandemic training and/or education looked like for hospital-based HCPs. In particular, there is no comprehensive description of pandemic education that covers: (1) what education was delivered, (2) how it was delivered, and (3) stakeholders’ experiences with education during this time. My thesis research aimed to fill these gaps using a multi-method approach, including a scoping review and semi-structured interviews with frontline HCPs and educators. I found that educational content primarily focussed on the topics of (1) clinical care of Covid-19 patients, and (2) infection prevention (including personal protective equipment use). Regarding instructional methods, I found that simulation and educational meetings were the most common. In terms of delivery, most activities were in-person; however, blended and virtual training was also prevalent. Stakeholders’ experiences highlighted both shared and unique challenges for HCP and educator groups. The interview results also suggested that HCPs hold differing opinions about content needs, instructional methods, and delivery. Overall, the findings provide an opportunity for providers, educators, and other healthcare leaders to reflect on training and education for the pandemic, and consider how to best develop supportive education both now and during future crises.

Developments of Method of Market Completions in Mathematical Finance
Creators: Vasilev, Ilia
Publisher: name: University of Alberta Library
Year: 2023

In present thesis I focus on development of method of market completions and its applications to various problems in pricing and hedging of contingent claims.

Since theory of mathematical finance is well developed  on complete markets, and corresponding solutions are well understood, method of market completions emerges as a naturall idea for applying knowledge available for complete markets to the case of incomplete one.

Key approach of proposed method is to introduce family of possible “completed” versions of initially incomplete market, parametrized by the set of special auxiliary assets. This manipulation leads to multiple subproblems, that could be solved by the means of known complete market techniques. Further, having corresponding family of solutions, I demonstrate how one could come up with criteria to choose optimal solution for initial market which would not depend on auxiliary assets.

I start with discussion of reasons for market incompleteness and introduce market completions for parametrization of completed versions of the market.

Then, I demonstrate how proposed method can be applied for fundamental problems of utility maximization, including not-necessarily concave utility function and pricing of contingent claims.

Then, I move to another important group of problems in the field of mathematical finance -- hedging of contingent claims. In the modern risk management industry, however it is more common to choose partial hedging, since it allows for more flexibility and money savings. I will start with discussing application of method of market completions for fundamental problems of quantile and effective hedging and then for modern risk-measures approach. I will also provide numerical examples for solutions on incomplete market.

It is known that the key element of this problem is a risk measure chosen for assessment of risks. Two of the most widely used risk measures in the industry nowadays are Value-at-Risk (VaR) and Expected Shortfall (CVaR). However, it has been demonstrated recently that both of these measures could be incorporated into one two-parametric risk measure called Range Value-at-Risk (RVaR). I will focus on demonstration that partial hedging problem with respect to both CVaR and RVaR in incomplete market could be approached with the help of method of market completions through the Utility Maximization task embedded into RVaR optimization problem.

Conclusions and further research directions in exploring the ideas of Method of market completions are in the last chapter.
Interactions of Water Droplets in Organic Media
Creators: Afsaneh, Hadi
Publisher: name: University of Alberta Library
Year: 2023

Emulsion droplets are present in various systems and their dynamic behaviors are important to the design of efficient processes in different biological and industrial applications. Studying the interaction mechanisms of deformable droplets provides fundamental insights into many unsolved problems in the field of droplet dynamics. Also, the properties of the thin liquid film between droplets during their interactions is of significant importance in the stability of emulsions. During the past few years, oil-in-water systems have been the center of attention in many theoretical and experimental studies due to their numerous applications, and hence, the dynamic behaviors of oil droplets inside aqueous solutions are well understood. However, water-in-oil systems are relatively new and require more studies to fully appreciate the underlying interaction mechanisms of water droplets within surrounding oil phases. Our investigations show that the Stokes–Reynolds–Young–Laplace model, as the currently established model for the study of droplet interaction in a medium, does not describe the experimental force versus piezo-displacement data for two water droplets inside a pure oil medium in the literature, and a further relatively long-ranged attractive force is required to explain these observations. In this study, we hypothesize that the source of the unexplored long-ranged force pertains to the presence of charges at the interface of the water drops with the oil phase. We propose fixed-surface-charge–bulk-dipole attraction, or charge–dipole interaction for short, as a new interaction force between water-in-oil droplets and then derive an equation for its disjoining pressure to add into the current Stokes–Reynolds–Young–Laplace model. The numerical results demonstrate that the force versus piezo-displacement curves deviate from experimental data in the literature in the absence of charge–dipole attraction while they are in excellent agreement with experimental data when charge–dipole attraction is included. Furthermore, we mathematically prove that electric double layer and surface electrostatic interactions are absent between two water droplets inside a pure organic phase as suggested by the experimental data, and therefore van der Waals and charge–dipole interactions are the only intermolecular and surface forces between water drops immersed within a pure oil medium. Our mathematical derivations show that although charges are present at the interface of water with a pure oil phase, no electrostatic interaction is present. This research indicates that charge–dipole attraction can adequately explain the unexplained attractive force observed in literature and provides a critical foundation for the study of water-in-oil emulsions with significant implications in different industries.

Natural ventilation models are becoming increasingly popular with increasing environmental awareness and the adverse effect of mechanical ventilation systems on the environment. Though simple in their working principle, natural ventilation models are challenging to control in meeting the thermal comfort demands of the occupants in changing weather conditions. This requires robust environment control and precise climatic parameters prediction for satisfactory performance. This study aims to design and assess the performance of optimal controllers for natural ventilation. Three optimal controllers, Linear Quadratic Regulator (LQR), Linear Quadratic Integral (LQI), and Linear Quadratic Gaussian (LQG), have been developed and assessed for their performance for thermal comfort for a naturally ventilated modeled with its window as the control input. In addition to these three controllers, another more efficient optimal predictive controller known as Model Predictive Controller is also designed and applied to the natural ventilation system. The three controllers are also compared with a Model Predictive Controller (MPC). Considering natural ventilation as a natural process with slower changing dynamics and subjected to various external and internal system uncertainties, the MPC is shown to outperform the other optimal controllers in terms of robust temperature prediction and control, efficient disturbance rejection, and uncertainty handling. Another challenge addressed by the study is the development of a simplified mathematical model that can be utilized for building a robust real-time controller. With an efficient runtime of 0.08 sec per optimization, the MPC shows robust temperature control by providing thermal comfort to users. This is achieved with a Predicted Mean Vote (PMV) index of 0.0013, which shows the controller performs effectively to keep the thermal comfort of the occupants to an acceptable level.

description: Computer viruses are evolving by developing spreading mechanisms based on the use of multiple vectors of propagation. The use of the social network as an extra vector of attack to penetrate the security measures in IP networks is improving the effectiveness of malware, and have therefore been used by the most aggressive viruses, like Conficker and Stuxnet. In this work we use interdependent networks to model the propagation of these kind of viruses. In particular, we study the propagation of a SIS model on interdependent networks where the state of each node is layer-independent and the dynamics in each network follows either a contact process or a reactive process, with different propagation rates. We apply this study to the case of existing multilayer networks, namely a Spanish scientific community of Statistical Physics, formed by a social network of scientific collaborations and a physical network of connected computers in each institution. We show that the interplay between layers increases dramatically the infectivity of viruses in the long term and their robustness against immunization.

description: Magnetic nanoparticles (MNPs) are used in many biomedical applications, including sentinel lymph node biopsy (SLNB) and magnetic particle imaging (MPI). DiffMag handheld probe ,based upon nonlinear detection principles has been developed by University of Twente for SLNB with MNPs. This method uses an excitation coil to activate the MNPs, and a detection coil to acquire the consequent magnetization of the MNPs. The hydrodynamic size and surface properties of MNPs are changed when introduced to new environment with different viscosity. Consequently, the number of mechanical degrees of freedom for rotation and translation in MNPs is reduced. This alteration in mechanical behavior has an effect on their magnetic behavior and particles Brownian relaxation time. In this study, we optimize the protocol settings for the nonlinear handheld detection probe during the SLNB procedure and investigate the detection depth in two environments.

description: An on-going debate in the energy economics and power market community has raised the question if energy-only power markets are increasingly failing due to growing feed-in shares from subsidized renewable energy sources (RES). The short answer to this is: No, they are not failing. Energy-based power markets are, however, facing several market distortions, namely from the gap between the electricity volume traded at day-ahead markets versus the overall electricity consumption as well as the (wrong) regulatory assumption that variable RES generation, i.e., wind and photovoltaic (PV), truly have zero marginal operation costs. In this paper we show that both effects over-amplify the well-known merit-order effect of RES power feed-in beyond a level that is explainable by underlying physical realities, i.e., thermal power plants being willing to accept negative electricity prices to be able to stay online due to considerations of wear & tear and start-stop constraints. We analyze the impacts of wind and PV power feed-in on the day-ahead market for a region that is already today experiencing significant feed-in tariff (FIT)-subsidized RES power feed-in, the EPEX German-Austrian market zone ($\approx\,$20% FIT share). Our analysis shows that, if the necessary regulatory adaptations are taken, i.e., increasing the day-ahead market's share of overall load demand and using the true marginal costs of RES units in the merit-order, energy-based power markets can remain functional despite high RES power feed-in.

Data-driven approaches to defining material property and performance relationships of armor ceramics undergoing dynamic loading
Creators: Yang, Shuo
Publisher: name: University of Alberta Library
Year: 2023

This thesis utilizes a combined numerical and machine learning approach to explorethe performance of an alumina ceramic tile undergoing high-velocity impact. The fi-nite element model is established by incorporating a user-defined Johnson-Holmquist-Beissel (JHB) material model within the framework of smoothed particle hydrody-namics (SPH) in LS-DYNA finite element software. The computational frameworkis validated across a range of conditions by matching the simulation results fromboth plate impact experiments and ballistic testing from the literature. Once vali-dated, the model is used to generate training data sets for an artificial neural network(ANN) to predict the residual velocity and projectile erosion of an alumina ceramictile undergoing high-velocity impact in the SPH framework. The ANN is then used toperform a sensitivity analysis involving exploring the effect of mechanical properties(e.g., strength and shear modulus) and impact simulation geometries (e.g., the thick-ness of ceramic tile) on material performance (i.e., residual projectile velocity anderosion). Overall, this study shows the capability of the hybrid FEM-ANN approachin studying the high-velocity impact on ceramic tiles and is applicable to guide thestructural-scale design of ceramic-based protection systems.

description: There are several approaches to extend General Relativity in order to explain the phenomena related to the Dark Matter and Dark Energy. These theories, generally called Extended Theories of Gravity, can be tested using observations coming from relativistic binary systems as PSR $J0348+0432$. Using a class of analytical $f(R)$-theories, one can construct the first time derivative of orbital period of the binary systems starting from a quadrupolar gravitational emission. Our aim is to set boundaries on the parameters of the theory in order to understand if they are ruled out, or not, by the observations on PSR $J0348+0432$. Finally, we have computed an upper limit on the graviton mass showing that agree with constraint coming from other observations.

description: PACIAE, a parton and hadron cascade model, is utilized to systematically investigate strange particle production and strangeness enhancement in Au+Au collision and in Pb+Pb collision with the 200GeV at RHIC and 2.76TeV at LHC, respectively. The experimental results at different centrality, which come from the STAR collaboration and the ALICE collaboration, are well described by the PACIAE model. This may represent the importance of the parton and hadron rescatterings, as well as the reduction mechanism of strange quark suppression, added in the PACIAE model.

description: The recently observed unconventional ferroelectricity in AB bilayer graphene sandwiched by hexagonal Boron Nitride (hBN) presents a new platform to manipulate correlated phases in multilayered van der Waals heterostructures. We present a low-energy continuum model for AB bilayer graphene encapsulated by the top and bottom layers of either hBN or graphene, with two independent twist angles. For the graphene/hBN heterostructures, we show that twist angle asymmetry leads to a layer polarization of the valence and conduction bands. We also show that an out-of-plane displacement field not only tunes the layer polarization but also flattens the low-energy bands. We extend the model to show that the electronic structures of quadrilayer graphene heterostructure consisting of AB bilayer graphene encapsulated by the top and bottom graphene layers can similarly be tuned by an external electric field.
