Dietary choices in Canadian South Asian adolescents
Creators: name: Thind, Shevonne Kaur
Publisher: name: University of British Columbia
Year: 2015

description: Purpose: Current literature identifies protective factors to healthy eating within the adolescent population, such as family meals, yet it fails to acknowledge variation between families and the difference in family structure associated with South Asian culture. The purpose of this descriptive study is to examine the food choices of South Asian adolescents and the extent to which food choices among Canadian-born South Asian adolescents are influenced by their home environment. Methods: A secondary analysis was conducted of the 2013 Adolescent Health Survey. The sample included adolescents who self-selected as South Asian. Measures included sex, immigrant status, yesterday food and drink choices, cultural connectedness and parental presence at evening meals. Differences in food and drink choices were analyzed for foreign-born and Canadian-born adolescents by sex using cross tabulations. Overall healthy versus less healthy eating was analyzed for foreign-born and Canadian-born adolescents by sex using logistic regression adjusting for significant variables, Results: Canadian-born South Asian adolescent males (p<.01) were half as likely to eat healthy than their foreign-born peers when controlling for parental presence at evening meals and engagement in cultural activities. Even after controlling for immigrant status and parental presence at evening meals, both South Asian adolescent males and females who engage in cultural activities (outside of school) weekly are 1.5 times more likely to eat healthy than those who never engage in cultural activities (outside of school) (p<.05). South Asian adolescent females (p<.01) with consistent parental presence at evening meals are 1.6 times more likely to eat healthy than those with inconsistent parental presence at evening meals. Discussion and Implications: This study draws attention to the heterogeneity that exists within this group of adolescents. Country of birth was an important variable, particularly for males. Although this relationship was not seen in females, the value of family meal times for females over males demonstrates that, in addition to country of birth, key sex differences exist with regards to dietary choices in this population. Future research should seek to understand the complex mechanisms which increase the risk of less healthy eating for Canadian-born South Asian adolescent males.

description: Multi-robot systems such as swarms of aerial robots are naturally suited to offer additional flexibility, resilience, and robustness in several tasks compared to a single robot by enabling cooperation among the agents. To enhance the autonomous robot decision-making process and situational awareness, multi-robot systems have to coordinate their perception capabilities to collect, share, and fuse environment information among the agents in an efficient and meaningful way such to accurately obtain context-appropriate information or gain resilience to sensor noise or failures. In this paper, we propose a general-purpose Graph Neural Network (GNN) with the main goal to increase, in multi-robot perception tasks, single robots' inference perception accuracy as well as resilience to sensor failures and disturbances. We show that the proposed framework can address multi-view visual perception problems such as monocular depth estimation and semantic segmentation. Several experiments both using photo-realistic and real data gathered from multiple aerial robots' viewpoints show the effectiveness of the proposed approach in challenging inference conditions including images corrupted by heavy noise and camera occlusions or failures.

description: We use the redshift Hubble parameter $H(z)$ data derived from relative galaxy ages, distant type Ia supernovae (SNe Ia), the Baryonic Acoustic Oscillation (BAO) peak, and the Cosmic Microwave Background (CMB) shift parameter data, to constrain cosmological parameters in the Undulant Universe. We marginalize the likelihood functions over $h$ by integrating the probability density $P\propto e^{-χ^2/2}$. By using the Markov Chain Monte Carlo (MCMC) technique, we obtain the best fitting results and give the confidence regions on the $b-Ω_{\rm m0}$ plane. Then we compare their constraints. Our results show that the $H(z)$ data play a similar role with the SNe Ia data in cosmological study. By presenting the independent and joint constraints, we find that the BAO and CMB data play very important roles in breaking the degeneracy compared with the $H(z)$ and SNe Ia data alone. Combined with the BAO or CMB data, one can improve the constraints remarkably. The SNe Ia data sets constrain $Ω_{\rm m0}$ much tighter than the $H(z)$ data sets, but the $H(z)$ data sets constrain $b$ much tighter than the SNe Ia data sets. All these results show that the Undulant Universe approaches the $Λ\rm$CDM model. We expect more $H(z)$ data to constrain cosmological parameters in future.

Evaluating the feasibility of quantifying spinal cord swelling as a function of pressure using fiber optic pressure sensors
Creators: name: Soicher, Jacqueline
Publisher: name: University of British Columbia
Year: 2015

description: Post traumatic spinal cord swelling can occur as a result of a spinal cord injury and may have negative effects on a patient’s neurological outcome. Spinal cord swelling is hypothesized to be associated with an increased pressure in the cord tissue. Experimental measurement of pressure in the in vivo cord would facilitate the study of spinal cord swelling and its effects. The spinal cord is a soft biological tissue consisting of fluid and solid components in which measuring and interpreting pressure is challenging. The objective of this research was to evaluate the feasibility of using fiber optic pressure sensors to directly measure intraparenchymal cord pressure. Fiber optic pressure sensors were used to measure intraparenchymal cord pressure in ex vivo pig cords under two conditions. A focal stress was incrementally applied to the cord to simulate sustained compression and decompression (i). Hydrostatic pressure was applied to the cord to simulate swelling (ii). The hydrostatic pressure was applied in three phases: a ramp to increase the pressure, a one hour hold at constant pressure and a ramp to decrease pressure using a fluid filled tank. During applied focal stress (i), results showed distinct intraparenchymal cord pressure increases and similar trends across trials. Most trials had a linear trend or region with strong correlations (r² > 0.9) between applied force and intraparenchymal cord pressure. However, when combining all trials, this association weakened (r² = 0.648). During ramping applied hydrostatic pressure (ii), the intraparenchymal cord pressure increase followed closely to the pressure in the surrounding fluid. In contrast, during the hold, the intraparenchymal cord pressure gradually increased while the pressure in the surrounding fluid remained unchanged. This resulted in a significant difference between the pressure changes seen in the cord and in the surrounding fluid. We conclude that the fiber optic pressure sensors are capable of measuring fluid pressure in spinal cord tissue. Based on the content of this thesis, we recommend the use of these sensors to examine relative intraparenchymal cord pressure in events occurring at a rate of 5 N/s up to 300 N in our in vivo porcine model for SCI.

This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site-to-site basis. At any site, it is important to understand the characteristics of both the soils and the underlying rock.

description: In this paper, we study two different phenomena (the Newman-Janis algorithm and the semiclassical Hamilton-Jacobi method) to analyze the Hawking temperature ($T_H$) for massive $4$-dimensional regular Hayward BH with spin parameter. First of all, we compute the rotating regular Hayward black hole solution by taking the Newman-Janis algorithmic rule. We derive the $T_H$ for rotating regular Hayward BH with the help of surface gravity. We have also analyzed the effects of spin parameter $a$ and free parameter $l$ on $T_H$ with the help of graphs. Moreover, we investigate the quantum corrected Hawking temperature ($T'_H$) for rotating regular Hayward black hole. To do so, we utilize the Lagrangian filed equation in the background of GUP within the concept of WKB approximation and semiclassical Hamilton-Jacobi method. The $T'_H$ of rotating regular Hayward BH depends upon correction parameter $β$, BH mass $m$, spin parameter $a$, free parameter $l$ and BH radius $r_+$. We also study the graphical behavior of $T'_H$ versus event horizon $r_+$ for rotating regular Hayward BH and check the influences of quantum gravity parameter $β$, spin parameter $a$ and free parameter $l$ on the stability of corresponding black hole. Moreover, we study the significance's of logarithmic entropy correction for regular rotating Hayward BH.

4D cone-beam CT image reconstruction of Varian TrueBeam v1.6 projection images for clinical quality assurance of stereotactic ablative radiotherapy to the lung
Creators: name: Beaudry, Joel
Publisher: name: University of British Columbia
Year: 2015

description: On-board cone-beam computed tomography (CBCT) imaging integrated with medical linear accelerators offers a viable tool for tumor localization just prior to radiation treatment delivery. However, the exact tumor location during treatment is not well-defined due to respiratory motion. This is taken into account during treatment planning by adding margins to the visible tumor volume defining the high dose region. The respiratory motion used to optimize the treatment plan is not guaranteed to be reproducible on the day of treatment, suggesting that the high dose region may not fully contain the tumor at all points of its trajectory during treatment. In this thesis, to image the tumor at the different portions of the breathing cycle, CBCT projections were binned by the respiratory signal at their time of acquisition. Reconstructing each bin created a 3D image depicting the tumor at one point of its trajectory. Combining the binned reconstructions added in a temporal component, defining a 4D-CBCT. 4D-CBCT reconstructions were performed on 6 stereotactic ablative radiotherapy (SABR) lung cancer patients. Imaging was performed using the Varian TrueBeam (v1.6) and respiratory information was captured with the infra-red camera-based Varian real-time position management (RPM) system. Both analytical and iterative reconstruction algorithms, and image quality metrics were used for a comparative study. Tumor motion was measured by tracking the visible tumor volume centroid from each 4D-CBCT image. The high dose regions defined during treatment planning were compared to the 4D-CBCT tumor volume during its trajectory using an overlap metric to determine if the tumor remained confined to the treatment volume, or not. 4D-CBCTs were found to be well reconstructed using iterative methods. When viewed sequentially the 4D-CBCT images visibly show tumor motion following a sinusoidal-like behavior. Examination of the tumor motion and overlap metric verify that the margins currently used to define the high dose region fully encompass the tumor during all times of its trajectory, i.e 100% overlap within error. The results indicate the current margins used for SABR patients at the British Columbia Cancer Agency are sufficient in providing adequate tumor coverage when accounting for tumor motion and setup uncertainties.

description: In the Penrose process and the Blandford-Znajek mechanism, the rotational energy of a black hole (BH) is extracted via particle fission and magnetic tension, respectively. Recently, inspired by a fundamental trait in plasma astrophysics known as magnetic reconnection (MR), a new energy extraction mechanism based on the fast reconnection of the magnetic field lines inside the ergosphere has been proposed by Comisso and Asenjo. In this paper, we investigate energy extraction caused by MR in the ergosphere of a rapidly spinning BH with broken Lorentz symmetry by a background bumblebee vector field. The desired rotating BH solution differentiates from the standard Kerr BH via the Lorentz symmetry breaking (LSB) parameter $l$, which comes from nonminimal coupling between the bumblebee field with nonzero vacuum expectation value and gravity. We find that incorporating $l<0$ in the background is in the interest of the energy extraction via MR for the fast-spinning BH surrounded by the plasma with weak magnetization, below what is expected from the scenario by Comisso and Asenjo. Our analysis robustly indicates that the power of energy extraction and efficiency of the plasma energization process through fast MR is more efficient than the Comisso-Asenjo solution, provided that the LSB parameter is negative, $l<0$. Compared to the Blandford-Znajek mechanism arising from the underlying background, we also show that MR is a more efficient energy extraction mechanism if $l<0$.

description: In diesem Artikel wird eine Reglerentwurfsmethode für polynomiale Systeme mit Stellgrößenbeschränkungen vorgestellt, die auf der Sum-of-squaresZerlegung von Polynomen basiert. Die betrachteten Regelgesetze bestehen aus einer Komposition der Sättigungsfunktion und einer polynomialen bzw. gebrochen rationalen Funktion. Neben dem Regelgesetz errechnet die Methode eine Abschätzung des Einzugsgebiets. Es werden zwei mögliche Entwurfsziele betrachtet: Die Konvergenzrate und die Größe des Einzugsgebiets. Das dem Entwurf zu Grunde liegende Optimierungsproblem ist multilinear in den Parametern und daher nicht konvex. Deshalb wird ein Algorithmus zur lokalen Optimierung solcher nichtkonvexen Probleme vorgeschlagen, der zur Lösung des zuvor aufgestellten Entwurfsproblems verwendet wird. Anhand eines Beispielsystems werden die Ergebnisse illustriert.

description: Co2-based Heusler compounds are the promising materials for the spintronics application due to their high Curie temperature, large spin-polarization, large magnetization density, and exotic transport properties. In the present manuscript, we report the anomalous Hall effect (AHE) in a polycrystalline Co2FeAl Heusler compound using combined experimental and theoretical studies. The Rietveld analysis of high-resolution synchrotron x-ray diffraction data reveals a large degree (~50 %) of antisite disorder between Fe and Al atoms. The analysis of anomalous transport data provides the experimental anomalous Hall conductivity (AHC) about 227 S/cm at 2 K with an intrinsic contribution of 155 S/cm, which has nearly constant variation with temperature. The detailed scaling analysis of anomalous Hall resistivity suggests that the AHE in Co2FeAl is governed by the Berry phase driven intrinsic mechanism. Our theoretical calculations reveal that the disorder present in Co2FeAl compound enhances the Berry curvature induced intrinsic AHC.

description: As algorithms and computing power have advanced, lattice QCD has become a precision technique for many QCD observables. However, the calculation of nucleon matrix elements remains an open challenge. I summarize the status of the lattice effort by examining one observable that has come to represent this challenge, average-x: the fraction of the nucleon's momentum carried by its quark constituents. Recent results confirm a long standing tendency to overshoot the experimentally measured value. Understanding this puzzle is essential to not only the lattice calculation of nucleon properties but also the broader effort to determine hadron structure from QCD.

description: We find a surprising connection between asymptotically flat space-times and non-relativistic conformal systems in one lower dimension. The BMS group is the group of asymptotic isometries of flat Minkowski space at null infinity. This is known to be infinite dimensional in three and four dimensions. We show that the BMS algebra in 3 dimensions is the same as the 2D Galilean Conformal Algebra which is of relevance to non-relativistic conformal symmetries. We further justify our proposal by looking at a Penrose limit of a radially infalling null ray inspired by non-relativistic scaling and obtain a flat metric. The 4D BMS algebra is also discussed and found to be the same as another class of GCA, called the semi-GCA, in three dimensions. We propose a general BMS/GCA correspondence. Some consequences are discussed.

description: Weiche strukturvariable Regler mit impliziten Ljapunov-Funktionen sind nichtlineare Zustandsrückführungen für lineare Systeme mit Stellgrößenbeschränkung. Die Parameter des Reglers werden kontinuierlich abhängig vom Systemzustand verändert, sodass der Stellgrößenbereich möglichst gut ausgenutzt wird, ohne die Beschränkung zu verletzen. Dadurch kann ein fast zeitoptimales Verhalten bei einem verhältnismäßig geringen Entwurfsaufwand erreicht werden. Dieser Entwurf erfolgt durch die numerische Lösung eines Optimierungsproblems mittels eines Suchverfahrens, z. B. einer Evolutionsstrategie. Der Entwurfsaufwand wird in diesem Artikel durch Formulierung dieses Problems als LMI (lineare Matrixungleichung) basiertes Optimierungsproblem deutlich verringert.
Laser-induced thermoelectric energy generation using carbon nanotube forests
Creators: name: Fan, Harrison Daniel Earl
Publisher: name: University of British Columbia
Year: 2015

description: Although there has been extensive research on the thermoelectric effect, there have only been some reports on the photo-thermoelectric effect in carbon nanotubes, i.e. the conversion of light to heat to electricity. A device capable of producing a thermoelectric voltage by light irradiation on a forest of aligned multi-walled carbon nanotubes has not yet been reported. The work presented in this thesis first outlines the growth conditions by which millimetre-long CNTs were grown by catalytic chemical vapour deposition (CVD). Two novel thermoelectric devices were fabricated based on two intrinsic properties of CNT forests. (1) Using the “Heat Trap” effect (light-induced heat localization), the first device induced a potential difference (few hundred μV) from low incident laser power. The temporal dynamics of the induced voltage were understood to be due to a competition of the temperature gradients within the device materials. A finite element analysis model was simulated the thermal and electrical characteristics. The temperature-dependent thermal conductivity of CNTs was derived based on the experimental induced voltage and was seen to fall-off with temperature, confirming a previously-suggested mechanism for the effect. (2) Since the thermal conductivity of CNTs can be 1-2 orders of magnitude smaller in the direction perpendicular to the nanotube axis, a second device was fabricated to achieve a higher temperature gradient. Under a few hundred mW of laser power, a few mV of potential difference was induced, indicating power conversion efficiencies in the 10ˉ⁵ % range. A finite element analysis model was created, which by using the experimentally-derived thermal conductivity from the previous device, predicted the induced voltage to within 10% at high laser powers. Calculation of the room temperature figure-of-merit ZT was low (10ˉ⁶ range), however no device optimization had been performed in these proof-of-concept prototypes. If CNT-based thermoelectric devices are to be used at higher temperatures, the three temperature-dependent material parameters enhance ZT and the efficiency. CNTs can be a promising material choice if cost and low toxicity are concerns, since the CVD process is fairly inexpensive and carbon-containing precursors are abundant. Moreover, CNTs have a high power-to-weight ratio and CNT forests are sparse.

description: We measure the penetration depth $λ_{ab}(T)$ in Ba(Fe$_{1-x}$Co$_{x}$)$_2$As$_2$ using local techniques that do not average over the sample. The superfluid density $ρ_s(T)\equiv1/λ_{ab}(T)^2$ has three main features. First, $ρ_s(T=0)$ falls sharply on the underdoped side of the dome. Second, $λ_{ab}(T)$ is flat at low $T$ at optimal doping, indicating fully gapped superconductivity, but varies more strongly in underdoped and overdoped samples, consistent with either a power law or a small second gap. Third, $ρ_s(T)$ varies steeply near $T_c$ for optimal and underdoping. These observations are consistent with an interplay between magnetic and superconducting phases.

description: We present results of field investigations of the biogeochemistry of an aquifer a few km from the ocean adjacent to the Fraser River in Vancouver, Canada. At the site, a wedge of relatively dense saline ocean water enters the aquifer in the hyporheic zone at the river bottom, migrates away from the river along the base of the aquifer to a maximum distance of approximately 500m inland, where it overturns and mixes with fresh groundwater. The mixed saline - fresh water then flows back under a regional freshwater gradient and eventually discharges to the river at the top of the saline wedge. Pore waters show iron concentrations peak at over 300 mg/L (5.4 mM) and manganese at 7 mg/L (0.13 mM) at the upper mixing zone - the interface between terrestrial recharge and top of the overturned saline groundwater. The reducible concentrations on the sediment are approximately 784-2,576 mg/kg (14-46 mM/kg) iron and 110-330 mg/kg (2-6mM/kg) manganese. The dominant process is the reductive dissolution of iron and manganese oxide minerals via organic matter oxidation, although acid-volatile sulfide and methane measurements show that both sulfate reduction and methanogenesis are also occurring. Dissolved organic matter (DOM) concentrations ranged between 5 and 30 mg/L. Excitation – emission fluorescence spectroscopy is used to help identify the distinct sources of DOM, which include terrestrial from fresh recharge, detrital from sediments and from inflowing ocean water. One-dimensional kinetic reactive-transport modeling that includes primary mineral redox reactions and secondary mineral precipitation was used to: i) interpret the role of mixing of fresh and saline water, ii) to constrain reduction-rate parameters and metabolic activity levels from field data, including the oxidation rate of organic matter by iron and manganese oxides, probably accompanied with sulfate reduction and methanogenesis; iii) to understand how other secondary minerals further control aqueous ferrous iron and manganese concentrations through mineral precipitation/dissolution processes; v) to gain insight into the long-term evolution of the geochemistry at the site.

description: The energy dependence of charged-hadron production in proton-proton collisions at RHIC and LHC energies is investigated in a nonequilibrium-statistical relativistic diffusion model (RDM) with three sources for particle production. Calculated charged-hadron pseudorapidity distributions for pp at RHIC energies of sqrt(s) = 0.2 and 0.41 TeV, and at LHC energies of 0.9, 2.36 and 7 TeV are optimized with respect to the available data. Predictions for 14 TeV are made. The central source arising from gluon-gluon collisions becomes the major origin of particle production at LHC energies. The midrapidity dip is essentially determined by the interplay of the three sources.

Classical and Quantum Annealing in the Median of Three Satisfiability

description: We determine the classical and quantum complexities of a specific ensemble of three-satisfiability problems with a unique satisfying assignment for up to N=100 and N=80 variables, respectively. In the classical limit we employ generalized ensemble techniques and measure the time that a Markovian Monte Carlo process spends in searching classical ground states. In the quantum limit we determine the maximum finite correlation length along a quantum adiabatic trajectory determined by the linear sweep of the adiabatic control parameter in the Hamiltonian composed of the problem Hamiltonian and the constant transverse field Hamiltonian. In the median of our ensemble both complexities diverge exponentially with the number of variables. Hence, standard, conventional adiabatic quantum computation fails to reduce the computational complexity to polynomial. Moreover, the growth-rate constant in the quantum limit is 3.8 times as large as the one in the classical limit, making classical fluctuations more beneficial than quantum fluctuations in ground-state searches.

A Study of Hizbullah’s Promotional Communication (2006-2018)
Creators: name: Hamdar, Sarah
Publisher: name: Goldsmiths, University of London
Year: 2021

description: This thesis draws on the conceptual tools of communication theory, and on studies of promotion and branding, to examine Hizbullah’s communication strategy and the way the Party has promoted its identity, values and nationalist discourses in the period between 2006 and 2018. To do so, it examines five different sites including buildings and leisure sites in Dahiya, ʿAshura rituals and their mediation on al-Manar, ʿAshura posters, and children’s magazines and television programming. 

By paying particular attention to Hizbullah’s religious channels and activities such as ʿAshura rituals and posters, and treating them as part and parcel of the Party’s political communication strategies, the thesis emphasises an aspect of the Party’s communication practices that has so far remained largely overlooked. It understands the Party’s communication channels as educational and socialising agencies that seek to create and maintain Hizbullah’s religio-politico nation and to ensure the Party’s survival within an increasingly tense regional political environment. 

The thesis’s focus on the specific time period from the 2006 war with Israel until the present day shows that Hizbullah is expanding its resistance and nationalist discourses as it attempts to appeal to a wider local, Muslim, Arab and regional audience. The thesis argues that the Party does this as a tactical and pre-emptive calculation to gain support for a regional war yet to come with Israel. It draws on the modernist and ethno-symbolist schools of nationalism and argues that both are necessary in order to understand the Party’s multiple nationalisms. However, the thesis argues that core to Hizbullah’s nationalism is one centred around its religio-politico nation that adopts the Karbala battle for resistance activities against whatever Yazid that is declared. Hence, resistance and religion are intertwined within the Party’s discourse.

description: Research on computer vision systems for driver assistance resulted in a variety of isolated approaches mainly performing very specialized tasks like, e. g., lane keeping or traffic sign detection. However, for a full understanding of generic traffic situations, integrated and flexible approaches are needed. We here present a highly integrated vision architecture for an advanced driver assistance system inspired by human cognitive principles. The system uses an attention system as the flexible and generic front-end for all visual processing, allowing a task-specific scene decomposition and search for known objects (based on a short term memory) as well as generic object classes (based on a long term memory). Knowledge fusion, e. g., between an internal 3D representation and a reliable road detection module improves the system performance. The system heavily relies on top-down links to modulate lower processing levels, resulting in a high system robustness.
Distribution systems analysis and optimization

description: Distribution systems (DS) are the last stage of any large power system, delivering electricity to the end-users. Conventionally, simplicity of DS operation has been a priority over its optimality. However, with the recent advancements in the automation and measurement infrastructures, it is now possible to improve the efficiency of DS operation. In this dissertation, a load modeling procedure is proposed which takes advantage of the data available at the smart meters. An algorithm is proposed to decompose the load at each customer level using the smart meter measurements. The proposed load model represents the voltage dependence of loads according to the load composition. Based on the voltage-dependent load model, a linear power flow formulation is developed for DS analysis. The linear current flow equations are then proposed which calculate the branch flows directly without requiring the nodal voltages. Sensitivity factors in terms of current transfer and branch outage distribution factors are also derived using the linear power flow concept. The advantages of having a set of linear equations describing the system statics are demonstrated in a variety of DS optimization problems, such as topological reconfiguration, capacitor placement, and volt-VAR optimization. Using the linear current flow equations, the mixed-integer nonlinear programming problem of DS reconfiguration is reformulated into a mixed-integer quadratic/linear programming problem, which substantially reduces the computational burden of the nonlinear combinatorial problem. Besides developing a direct mathematical optimization approach, a fast heuristic method is also developed here for the minimum-loss network reconfiguration based on the minimum spanning tree problem. This heuristic method provides a good suboptimal solution to initialize the direct mathematical optimization approaches such as branch-and-cut algorithm used for solving combinatorial problems. Based on planar graph theory, an efficient mathematical formulation for the representation of the radiality constraint in reconfiguration problems is introduced. It is shown that this formulation is advantageous over the available methods in terms of accuracy and computational efficiency. The proposed algorithms are tested using a variety of DS benchmarks and promising results are achieved.

description: Colossal magnetoresistance (CMR) emerges from intertwined spin and charge degrees of freedom in the form of ferromagnetic clusters also known as trapped magnetic polarons. As a result, CMR is rarely observed in antiferromagnetic materials. Here we use electron spin resonance (ESR) to reveal microscopic evidence for the formation of magnetic polarons in antiferromagnetic Eu$_{5}$In$_{2}$Sb$_{6}$. First, we observe a reduction of the Eu$^{2+}$ ESR linewidth as a function of the applied magnetic field consistent with ferromagnetic clusters that are antiferromagnetically coupled. Additionally, the Eu$^{2+}$ lineshape changes markedly below T' ~ 200 K, a temperature scale that coincides with the onset of CMR. The combination of these two effects provide strong evidence that magnetic polarons grow in size below T' and start influencing the macroscopic properties of the system.

description: Nowadays, most users need more passwords than they can handle. Consequently, users have developed a multitude of strategies to cope with this situation. Some of these coping strategies are based on misconceptions about password security. In such cases, the users are unaware of their insecure password practices. Addressing the misconceptions is vital in order to decrease insecure coping strategies. We conducted a systematic literature review with the goal to provide an overview of the misconceptions about password security. Our literature review revealed that misconceptions exist in basically all aspects of password security. Furthermore, we developed interventions to address these misconceptions. Then, we evaluated the interventions' effectiveness in decreasing the misconceptions at three small and medium sized enterprises (SME). Our results show that the interventions decrease the overall prevalence of misconceptions significantly in the participating employees.
