description: The reachability problem for Vector Addition Systems (VASs) is a central problem of net theory. The general problem is known to be decidable by algorithms exclusively based on the classical Kosaraju-Lambert-Mayr-Sacerdote-Tenney decomposition. This decomposition is used in this paper to prove that the Parikh images of languages recognized by VASs are semi-pseudo-linear; a class that extends the semi-linear sets, a.k.a. the sets definable in Presburger arithmetic. We provide an application of this result; we prove that a final configuration is not reachable from an initial one if and only if there exists a semi-linear inductive invariant that contains the initial configuration but not the final one. Since we can decide if a Presburger formula denotes an inductive invariant, we deduce that there exist checkable certificates of non-reachability. In particular, there exists a simple algorithm for deciding the general VAS reachability problem based on two semi-algorithms. A first one that tries to prove the reachability by enumerating finite sequences of actions and a second one that tries to prove the non-reachability by enumerating Presburger formulas.

description: We apply a simple statistical mechanics cluster approximation for studying clustering in the Kern and Frenkel model of Janus fluids. The approach is motivated by recent Monte Carlo simulations work on the same model revealing that the vapor coexisting with the liquid phase contains clusters of different sizes and shapes whose equilibrium concentrations in general depend on the interaction range as well as on thermodynamic parameters. The approximation hinges on a separation between the intra- and inter-cluster contribution to thermodynamics, where only the former is explicitly computed by Monte Carlo simulations. Two levels of a simple liquid theory approximation are exploited for the description of the latter. In the first we use the ideal-gas expressions and obtain a qualitative agreement with extensive Monte Carlo bulk simulations. This can be improved to a semi-quantitative agreement, by using a hard-sphere description for the cluster-cluster correlations.

description: Organic/inorganic donor-acceptor interfaces are gaining growing attention in organic photovoltaic applications as each component of the interface offers unique attributes. Here we use hybrid-density functional theory to examine the electronic structure of sexithiophene/ZnO interfaces. We find that interfacial molecular orientations strongly influence the adsorption energy, the energy level alignment, and the open circuit voltage. We attribute the orientation dependence to the varied strength of electronic coupling between the molecule and the substrate. Our study suggests that photovoltaic performance can be optimized by controlling the interfacial design of molecular orientations.

description: One considers phase-space noncommutativity in the context of a Kantowski-Sachs cosmological model to study the interior of a Schwarzschild black hole. It is shown that the potential function of the corresponding quantum cosmology problem has a local minimum. One deduces the thermodynamics and show that the Hawking temperature and entropy exhibit an explicit dependence on the momentum noncommutativity regime and it is shown that the wave function vanishes in this limit.

description: \textit{Ab initio} random structure searching based on density functional theory is used to determine the ground-state structures of ice at high pressures. Including estimates of lattice zero-point energies, ice is found to adopt three novel crystal phases. The underlying sub-lattice of O atoms remains similar among them, and the transitions can be characterized by reorganizations of the hydrogen bonds. The symmetric hydrogen bonds of ice X and $Pbcm$ are initially lost as ice transforms to structures with symmetries $Pmc2_1$ (800 - 950 GPa) and $P2_1$ (1.17 TPa), but they are eventually regained at 5.62 TPa in a layered structure $C2/m$. The $P2_1 \rightarrow C2/m$ transformation also marks the insulator-to-metal transition in ice, which occurs at a significantly higher pressure than recently predicted.

Characterization and applications of paper spray ionization mass spectrometry
Creators: name: Alsaggaf, Wejdan Taha
Publisher: name: University of British Columbia
Year: 2015

description: A survey of literature indicates an increased interest in developing direct analysis of samples with minimum preparation. Paper spray ionization mass spectrometry (PSI/MS) was developed for this purpose over the last four years. More than 50 manuscripts have been published describing this technique but several aspects remain to be characterized and optimized. The overall objectives of this work are as follows: (i) to construct a lab-made PSI/MS set up and optimize parameters for the orientation of the paper substrate, (ii) to develop new achievement to understand the ionization mechanism, (iii) to understand the chemistry on the paper using different papers, (iv) to distinguish between solubility and micro-flow of the sample across PSI and liquid extraction surface analysis (LESA), (v) to demonstrate the potential of PSI as a metabolites fingerprinting technique (vi) to develop new approach for direct analysis of solid tissues without sample preparation, and (vii) to develop new achievement to understand the interaction between analyte and surface of the paper. Silica nanoparticles were used in this study. The orientation of the paper substrate and the optimal type of paper was determined. Interestingly, when the paper was dried in an oven to reduce a water content and non-polar solvents were used, the ionization was inhibited. When non-polar solvents were used on paper acclimatized to normal lab humidity, ionization was observed. These results indicate that residual water on the paper surface plays a role in the ionization mechanism. The results showed the hydrophilic properties of the paper leads PSI to be utilized as a separation/ionization technique at one-step. The sensitivity was compared over two instruments and two surface ionization techniques. The results showed better peak response in the MS/MS system. It was demonstrated that PSI has low accuracy to obtain a profile for complex samples such as saffron. Mechanical press extraction and paper substrate coated with silica nanoparticles were developed as potential improvements for the PSI method. Together, the data in this study demonstrate the potential of PSI as an alternative technique for direct analysis.

description: Chitosan as a biobased polymer is gaining increasing attention due to its extraordinary physico-chemical characteristics and properties. While a primary use of chitosan has been in horticultural and agricultural applications for plant defense and to increase crop yield, recent research reports display various new utilizations in the field of advanced biomedical devices, targeted drug delivery, and as bioimaging sensors. Chitosan possesses multiple characteristics such as antimicrobial properties, stimuli-responsiveness, tunable mechanical strength, biocompatibility, biodegradability, and water-solubility. Further, chitosan can be processed into nanoparticles, nano-vehicles, nanocapsules, scaffolds, fiber meshes, and 3D printed scaffolds for a variety of applications. In recent times, nanoparticles incorporated in chitosan matrices have been identified to show superior biological activity, as cells tend to proliferate/differentiate faster when they interact with nanocomposites rather than bulk or micron size substrates/scaffolds. The present article intents to cover chitosan-based nanocomposites used for regenerative medicine, wound dressings, drug delivery, and biosensing applications.

description: Katharina Hahn, M.a., Universität Leipzig: „Stadtbildpolitik im Fotobuch. Köln und Dresden nach 1945“ Städtische Selbstdarstellungen dienen seit Jahrhunderten der Beeinflussung der öffentlichen Meinung und des Wissens über Städte im Sinne einer städtischen Bildpolitik. Für das Dissertationsprojekt zur Stadtbildpolitik deutscher Städte nach dem Zweiten Weltkrieg werden Fotobücher über Köln und Dresden untersucht und verglichen, die zwischen 1945 und 1990 publiziert wurden. Diese Fotobücher sind visuelle Selbstrepräsentationen, da sie unter Beteiligung städtischer und teilweise auch staatlicher Akteur*innen konzipiert wurden. Die Botschaften über die Stadt, die diese Publikationen enthalten und die politischen Regeln, die zu ihrer Konzeption führten, bilden das Erkenntnisinteresse der explorativen Studie, die damit einen zentralen Aspekt städtischer Identitätsbildung in Ost- und Westdeutschland exemplarisch nachvollziehbar macht. Auf dem Poster wird veranschaulicht, auf welche Weise digitale Werkzeuge bei der Beantwortung dieser Frage helfen und wie methodisch dabei vorgegangen wird. Es wird eine innovative Form der Visualisierung vorgestellt und ein Ausblick auf die Anschlussfähigkeit des Projektes gegeben.

description: The nonlinear dynamics of outflows driven by magnetic explosion on the surface of a compact star is investigated through special relativistic magnetohydrodynamic simulations. We adopt, as the initial equilibrium state, a spherical stellar object embedded in hydrostatic plasma which has a density $ρ(r) \propto r^{- α}$ and is threaded by a dipole magnetic field. The injection of magnetic energy at the surface of compact star breaks the equilibrium and triggers a two-component outflow. At the early evolutionary stage, the magnetic pressure increases rapidly around the stellar surface, initiating a magnetically driven outflow. A strong forward shock driven outflow is then excited. The expansion velocity of the magnetically driven outflow is characterized by the Alfvén velocity on the stellar surface, and follows a simple scaling relation $v_{\rm mag} \propto {v_{\rm A}}^{1/2}$. When the initial density profile declines steeply with radius, the strong shock is accelerated self-similarly to relativistic velocity ahead of the magnetically driven component. We find that it evolves according to a self-similar relation $Γ_{\rm sh} \propto r_{\rm sh}$, where $Γ_{\rm sh}$ is the Lorentz factor of the plasma measured at the shock surface $r_{\rm sh}$. Purely hydrodynamic process would be responsible for the acceleration mechanism of the shock driven outflow. Our two-component outflow model, which is the natural outcome of the magnetic explosion, can provide a better understanding of the magnetic active phenomena on various magnetized compact stars.

description: We present results of an ab-initio study of the electronic structure of 140 rare earth compounds. Specifically we predict an electronic phase diagram of the entire range of rare earth monopnictides and monochalcogenides, composed of metallic, semiconducting and heavy fermion-like regions, and exhibiting valency transitions brought about by a complex interplay between ligand chemistry and lanthanide contraction. The calculations exploit the combined effect of a first-principles methodology, which can adequately describe the dual character of electrons, itinerant vs. localized, and high throughput computing made possible by the increasing available computational power. Our findings, including the predicted "intermediate valent" compounds SmO and TmSe, are in overall excellent agreement with the available experimental data. The accuracy of the approach, proven e.g. through the lattice parameters calculated to within 1.5% of the experimental values, and its ability to describe localization phenomena in solids, makes it a competitive atomistic simulation approach in the search for and design of new materials with specific physical properties and possible technological applications.

description: We probe the validity of Crooks' fluctuation relation on the fluctuating lattice-Boltzmann model (FLBM), a highly simplified lattice model for a thermal ideal gas. We drive the system between two thermodynamic equilibrium states and compute the distribution of the work performed. By comparing the distributions of the work performed during the forward driving and time reversed driving, we show that the system satisfies Crooks' relation. The results of the numerical experiment suggest that the temperature and the free energy of the system are well defined.

Rethinking the modern man : a generational analysis of masculine social pressures related to lifelong unions
Creators: name: Lymburner, Tyler Alexander
Publisher: name: University of British Columbia
Year: 2015

description: Individuals who choose not to couple live a unique experience. This study examines the evolution of the social pressures and expectations, directed toward men, in regards to choosing a partner and forming a lifelong union. The study gathered the attitudes, opinions, and experiences of adult Canadian males regarding this topic. The participants include men who have avoided lifelong unions, such as marriage and cohabitation, in the 1960s, and men who have avoided lifelong unions from 2005 to the present. The data for this study was created through conducting semi-structured interviews. I interviewed ten men who rejected lifelong unions in the 1960s, and ten men who have done so since 2005. I focused on the male experience because the majority of the existing sociological research pertaining to lifelong unions is centered on the couple, and focuses on the shared experience of marriage. I am interested in questioning marriage as a norm, and the research suggests socially accepted alternatives to coupling and lifelong unions. The study provides insight on how the experiences of single men have changed over the past fifty years. The results from the study suggest that marriage is still the norm, and that it is still difficult to question this norm. When the participants did not conform to the norm, they expressed being subject to stereotyping or discrimination. The study also suggests that the participants who are currently single experience less pressure to form a lifelong union than the participants who were single in the 1960s. However, the pressure to couple remains strong, and the participants who are currently single experience intense age-related pressure that increases the longer they remain single.

description: We present a theoretical approach to scale the artificially fast dynamics of simulated coarse-grained polymer liquids down to its realistic value. As coarse-graining affects entropy and dissipation, two factors enter the rescaling: inclusion of intramolecular vibrational degrees of freedom, and rescaling of the friction coefficient. Because our approach is analytical, it is general and transferable. Translational and rotational diffusion of unentangled and entangled polyethylene melts, predicted from mesoscale simulations of coarse-grained polymer melts using our rescaling procedure, are in quantitative agreement with united atom simulations and with experiments.

In this paper, we study the prospects for constraining the new agegraphic dark energy (NADE) model and the Ricci dark energy (RDE) model with the SL test. We show that, assuming only a ten-year survey, the SL test can constrain these two models with high significance.

Lattice-gas model for active vesicle transport by molecular motors with opposite polarities

description: We introduce a multi-species lattice gas model for motor protein driven collective cargo transport on cellular filaments. We use this model to describe and analyze the collective motion of interacting vesicle cargoes being carried by oppositely directed molecular motors, moving on a single biofilament. Building on a totally asymmetric exclusion process (TASEP) to characterize the motion of the interacting cargoes, we allow for mass exchange with the environment, input and output at filament boundaries and focus on the role of interconversion rates and how they affect the directionality of the net cargo transport. We quantify the effect of the various different competing processes in terms of non-equilibrium phase diagrams. The interplay of interconversion rates, which allow for flux reversal and evaporation/deposition processes introduce qualitatively new features in the phase diagrams. We observe regimes of three-phase coexistence, the possibility of phase re-entrance and a significant flexibility in how the different phase boundaries shift in response to changes in control parameters. The moving steady state solutions of this model allows for different possibilities for the spatial distribution of cargo vesicles, ranging from homogeneous distribution of vesicles to polarized distributions, characterized by inhomogeneities or {\it shocks}. Current reversals due to internal regulation emerge naturally within the framework of this model. We believe this minimal model will clarify the understanding of many features of collective vesicle transport, apart from serving as the basis for building more exact quantitative models for vesicle transport relevant to various {\it in-vivo} situations.
Formation of magnetic impurities and pair-breaking effect in a superfluid Fermi gas

description: We theoretically investigate a possible idea to introduce magnetic impurities to a superfluid Fermi gas. In the presence of population imbalance ($N_\uparrow>N_\downarrow$, where $N_σ$ is the number of Fermi atoms with pseudospin $σ=\uparrow,\downarrow$), we show that nonmagnetic potential scatterers embedded in the system are magnetized in the sense that some of excess $\uparrow$-spin atoms are localized around them. They destroy the superfluid order parameter around them, as in the case of magnetic impurity effect discussed in the superconductivity literature. This pair-breaking effect naturally leads to localized excited states below the superfluid excitation gap. To confirm our idea in a simply manner, we treat an attractive Fermi Hubbard model within the mean-field theory at T=0. We self-consistently determine superfluid properties around a nonmagnetic impurity, such as the superfluid order parameter, local population imbalance, as well as single-particle density of states, in the presence of population imbalance. Since the competition between superconductivity and magnetism is one of the most fundamental problems in condensed matter physics, our results would be useful for the study of this important issue in cold Fermi gases.

Design of a radio frequency heating system for electrolytic liquids and sludges
Creators: name: Ferdous, Md. Saimoom
Publisher: name: University of British Columbia
Year: 2015

description: A radio frequency (RF) heating system has been designed to heat electrolytic liquids and sludges in a pressurized test vessel. The RF heating system is designed to heat a 400 ml load volume at a frequency of 13.56 MHz using a 1 kW RF generator. The primary application for the heating system is to conduct experimental work on the pretreatment of waste activated sludge, a byproduct of wastewater treatment plants. The dielectric properties of waste activated sludge were analyzed and it was determined that ionic conduction heating at a low frequency would be more efficient than microwave heating at a frequency of 2.45 GHz. The RF heating system was tested with sludge and salt water loads over a temperature range of 20°C to 120°C. Power transfer efficiency from the generator to the load was excellent and exceeded 86% over the entire temperature range for both loads. An important part of this work was the design of the RF applicator. The applicator consists of two circular electrodes mounted inside a Teflon cylinder to uniformly heat the load. The Teflon cylinder has seals and can heat loads under pressure. The load cylinder is enclosed in a coaxial housing and the geometry of the load cylinder and enclosure are designed to provide a nominal impedance of 50 Ω to match the RF generator impedance. The applicator has a thermocouple embedded in an electrode and a software control system is implemented in LabView to adjust the generator power for a target ramp rate or to maintain a steady state temperature. Extensive electromagnetic simulations were done to verify and optimize the applicator design. Analytic, simulation and experimental results are compared and very good agreement is obtained.

description: We obtain an analytical expression for the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction $J$ in electron or hole doped graphene for linear Dirac bands. The results agree very well with the numerical calculations for the full tight-binding band structure in the regime where the linear band structure is valid. The analytical result, expressed in terms of the Meijer G-function, consists of a product of two oscillatory terms, one coming from the interference between the two Dirac cones and the second coming from the finite size of the Fermi surface. For large distances, the Meijer G-function behaves as a sinusoidal term, leading to the result $J \sim R^{-2} k_F \sin (2 k_F R) {1 + \cos[(K-K').R]}$ for moments located on the same sublattice. The $R^{-2}$ dependence, which is the same for the standard two-dimensional electron gas, is universal irrespective of the sublattice location and the distance direction of the two moments except when $k_F =0$ (undoped case), where it reverts to the $R^{-3}$ dependence. These results correct several inconsistencies found in the literature.

description: The most important cause of developing hereditary breast cancer is germline? Two of the most common susceptibility genes are BRCA1 and BRCA2. Germline mutations in BRCA1 and BRCA2 genes are the main genetic and inherited factors for breast and ovarian cancer. In fact, these mutations are very important in developing early-onset and increasing the risk of familial breast and? ovarian cancer and are responsible for 90% of hereditary BC cases. Therefore, according? to the conducted studies, screening of BRCA1 and BRCA2 genes is recommended as an important marker for early detection of all patients with breast or ovarian cancer risk with a family history of the disease
Solar dynamo model with nonlocal alpha-effect

description: The first results of the solar dynamo model that allows for the diamagnetic effect of inhomogeneous turbulence and the nonlocal alpha-effect due to the rise of magnetic loops are discussed. The nonlocal alpha-effect is not subject to the catastrophic quenching related to the conservation of magnetic helicity. Given the diamagnetic pumping, the magnetic fields are concentrated near the base of the convection zone, although the distributed-type model covers the entire thickness of the convection zone. The magnetic cycle period, the equatorial symmetry of the field, its meridional drift, and the polar-to-toroidal field ratio obtained in the model are in agreement with observations. There is also some disagreement with observations pointing the ways of improving the model.

description: In this theoretical study, we show that a simple endlessly single-mode photonic crystal fiber can be designed to yield, not just two, but three zero-dispersion wavelengths. The presence of a third dispersion zero creates a rich phase-matching topology, enabling enhanced control over the spectral locations of the four-wave-mixing and resonant-radiation bands emitted by solitons and short pulses. The greatly enhanced flexibility in the positioning of these bands has applications in wavelength conversion, supercontinuum generation and pair-photon sources for quantum optics.

description: Photosynthesis plays a central role as an energy source for plant metabolism, and its efficiency may be drastically reduced due to abiotic stresses. During acclimation to adverse environments, plants try to maintain the photosynthetic efficiency at as high a level as possible, avoiding the energy imbalance and the photo-oxidative damage. When plants are exposed to environmental stresses the availability of CO2 within the leaf (Ci) is restricted and/or the synthesis of ATP is impaired. Moreover, under abiotic stress conditions stomatal closure is caused, slowing CO2 assimilation and consequently reducing the photosynthetic rate. The uptake and release of CO2 in photosynthesis and the respiration and release of H2O during transpiration of plants or leaves is measured using gas-exchange systems.

Exploring undermining cooperation effect of reward in social dilemma contexts based on type of reward

Subjects: subject: Social and Behavioral Sciences

description: We aim to explore how rewards might potentially undermine cooperation. Drawing from the concept of the 'Removing the Sanction Paradigm' (RTS; Mulder et al., 2006), we will investigate whether discontinuing a reward causes the previously rewarded group to contribute less than a control group that was never rewarded. Past experiments using the RTS paradigm have typically compared two groups: an experimental group that participated in the public goods game with rewards and later without, and a control group that only played without rewards. In our study, we intend to experimentally vary the type of reward. Specifically, we will test two types of rewards: a 'normative reward' for contributions that exceed a set benchmark, and a 'competitive reward' for the highest contributions.

description: To assess the influence of steady-state concentration, duration of action and molecular weight of glucagon-like peptide-1 receptor (GLP-1RA) on efficacy and gastrointestinal (GI) side effects in patients with type 2 diabetes mellitus (T2DM). PubMed, EMBASE, the Cochrane Center Register of Controlled Trials for Studies and Clinicaltrial.gov were searched from inception to April 2022. Randomized controlled trials (RCTs) comparing GLP-1RA versus non-GLP-1RA agents in patients with T2DM were included. Sensitivity analyses on steady-state concentration, duration of action and molecular weight of GLP-1RA were conducted. 113 RCTs were included. Greater HbA1c reduction between GLP-1RA users versus non-GLP-1RA users was observed in the high-steady-state-concentration stratum and long-acting stratum compared with the low-steady-state-concentration stratum (Psubgroup difference = 0.0004) and short-acting stratum (Psubgroup difference<0.0001). The risk of GI adverse events in GLP-1RA users versus non-GLP-1RA users was decreased in the high-steady-state-concentration stratum, long-acting stratum and heavy-molecular-weight stratum compared with low-steady-state-concentration stratum (Psubgroup difference<0.0001), short-acting stratum (Psubgroup difference = 0.002) and light-molecular-weight stratum (Psubgroup difference = 0.0008). GLP-1RA with high steady-state concentration and long duration of action showed better hypoglycemic effect. GLP-1RA with high steady-state concentration, long duration of action and heavy molecular weight was associated with lower risk of GI adverse events.

description: Stellar jets can be highly asymmetric and have multiple velocity components. To clarify the origin of jet asymmetries and constrain their launch mechanism we study the physical and kinematical structure of the flow emitted by DG Tau B. The analysis of deep spectra taken at the KECK telescope allows us to infer the physical properties (the electron and total density, ne and nh, the ionisation fraction, xe, and the temperature, te) and the spatial distribution of the velocity components in the two jet lobes. The presence of dust grains in the jet is investigated by estimating the gas-phase abundance of calcium with respect to its solar value. At the base of the jet the lines are broad (~100 km/s) and up to three velocity components are detected. At 5" from the source, however, only the denser and more excited high velocity components survive and the lines are narrower (~10-30 km/s). The jet is strongly asymmetric both in velocity and in its physical structure. The red lobe, slower (~140 km/s) and more collimated, presents low ionisation fractions (xe~0.1-0.4) and temperatures (te<5e3 K), while the total density is up to ~2.5e4 ccm. The blue lobe, faster (~-320 km/s) and less collimated, is also less dense (nh~1e4 ccm) but highly excited (te up to ~5e4 K and xe up to 0.9). The estimated mass loss rate is similar in the two lobes (~6-8e-9 Msol/yr), suggesting that the ejection power is comparable on the two sides of the system, as expected from a magneto-centrifugal ejection mechanism, and that the observed asymmetries are due to different mass load and propagation properties in an inhomogeneous environment. Calcium is strongly depleted, indicating that the jet contains dust grains and, therefore, should originate from a region of the disk extending beyond the dust sublimation radius. The depletion is lower for higher velocities, consistent with dust destruction by shocks.

description: Type 2 diabetes mellitus (T2DM) is one of the leading causes of morbidity and mortality. Peptide-based multi-targeting agonists represent a new paradigm in metabolic pharmacology as they manifest multiplexed pharmacological actions over mono-agonists. Tirzepatide is a novel dual glucose-dependent insulinotropic polypeptide receptor (GIPR) and glucagon-like peptide-1 receptor (GLP-1R) agonist that has been recently approved by the FDA. This review aims to summarize the available evidence on the discovery, pharmacology, pharmacokinetic, pharmacodynamic, efficacy, and safety of tirzepatide in the pharmacotherapy of T2DM. We searched PubMed, Embase, and International Pharmaceutical Abstracts to identify relevant papers on tirzepatide use in T2DM. Clinical trial registries were also searched. Tirzepatide improves glycemic control compared to baseline, placebo, and active comparators. It is also associated with weight reduction and an improvement in some, but not all, dyslipidemia, cardiovascular risk, and nonalcoholic steatohepatitis (NASH) biomarkers. Tirzepatide has a favorable safety profile with a low risk of hypoglycemia; however, adverse events such as gastrointestinal reactions were frequently reported and sometimes even led to therapy discontinuation. Future research should focus on investigating the role of tirzepatide in obesity, NASH, and cardio-renal benefits. Real-world observational studies are also needed to assess rare and long-term adverse events.

description: Accreting neutron stars (NS) and accreting millisecond X-ray pulsars (AMXPs) are one of the most interesting laboratories to study the physics of compact objects. Recently, along with providing highly precise mass and radius measurements, NICER also indicted the requirement of complex magnetic field structures to explain the observed X-ray spectra in some of the isolated millisecond pulsars. Rotation-powered millisecond pulsars are assumed to have undergone significant magnetic field evolution during the accretion phase. However, the details of this process are still poorly understood. We performed a suite of GRMHD simulations of accretion onto neutron stars, contrasting dipolar with non-dipolar field structures. Besides exploring processes in different accretion regimes, the simulations inform on the variability properties of the hotspots which can aid in future pulse-profile modeling of accreting sources.
