Atmospheric aerosols

description: Secondary organic aerosols (SOA) play an important role in the Earth’s radiative budget due to their potential to either warm or cool the atmosphere through light absorption or light scattering, respectively, and to cool or warm the lower atmosphere by acting as cloud condensation nuclei. SOA are air-suspended liquid and semi-solid droplets that form through multiphase chemical processes. Atmospheric photochemical oxidation of volatile organic compounds (VOCs) in the presence of air pollutants, such as NOx (NO + NO2) and the OH radical, promote formation of low volatility organic products that eventually condense to form SOA. To better understand the sources and sinks, formation, and fate of SOA, laboratory studies investigating oxidation of a biogenic VOC as well as anthropogenic emissions of SOA precursors were conducted. The first study (Chapter 3) investigated the OH-initiated oxidation of β-ocimene, a biogenic volatile organic compound (BVOC) released from vegetation, including forests, agricultural landscapes, and grasslands emitted during the daytime. The oxidation of BVOCs in the presence of NOx leads to the formation of functionalized organic nitrate (RONO2) compounds and isomers that easily condense to form SOA. To understand their atmospheric fate, the RONO2 hydrolysis rate constants were quantified and found to be highly pH dependent. The findings of this study provide key insights into the formation and fate of organic nitrates and NOx cycling in forested environments from daytime monoterpenes that were not previously included in atmospheric models. The second study (Chapters 4 and 5) investigated condensed waste emissions generated during Cured-In-Place-Pipe (CIPP) installations. This installation process is the most popular, least expensive, and most frequently used technology that cures leaking sanitary and stormwater sewers. Waste plumes discharged during pipe manufacture are complex multi-phase mixtures of volatile and semi-volatile organic compounds (VOC and SVOC, respectively), primary organic aerosols and SOA, fine debris of partially cured resin, and direct emission of nanoplastic particles that are all blown into the atmospheric environment at significant concentrations at worksites. This work unveiled a direct emission source of airborne nanoplastic particles as well as substantial concentrations of hazardous compounds and SOA precursors that were previously unrecognized.

description: Passer de l’environnement de l’école primaire à l’école secondaire est à la fois une étape importante et un défi auquel sont confrontés la plupart des élèves. Les défis que présente cette transition sont dus aux disparités entre les cultures de l’école primaire et secondaire (Zeedyk et al., 2003). Bien que la majorité des enfants réussissent à faire face à ce changement, un nombre considérable d’élèves le vivent comme une période d’anxiété. Jindal-Snape & Miller (2008) considère la transition primaire-secondaire comme « a challenge of living » (un défi de vie), en raison des différents changements environnementaux et sociaux. Au Bénin sur 100 élèves qui entre au secondaire seulement 35 arrive a achevé avec succès le premier. La grande partie d’eux abandonne encours. A travers une étude qualitative auprès de 13 chefs d’établissement du primaire, 10 chefs d’établissement du secondaire et 3 inspecteurs du bénin, cette communication apporte des éclaircissements sur l’accrochage et le décrochage dans un contexte béninois en particulier. Elle se base sur les expériences de ces différents acteurs pour proposer des pistes de solutions pouvant non seulement améliorer la rétention scolaire des élèves mais aussi la qualité des formations et la performance scolaire des élèves. Nos résultats suggèrent que le décrochage pendant la transition primaire-secondaire est construit à partir d’une action conjuguée de plusieurs facteurs (individuel, scolaires et familiaux). Ces résultats mettent en exergue la discontinuité entre les programmes du primaire et du secondaire. Les chefs d’établissement attirent également l’attention sur une remarquable passiveté des parents et du système scolaire dans l’appui psychologique et technique pour faciliter la transition aux élèves, surtout des élèves « vulnérables ».

description: Various geochemical proxies have been developed to determine if ancient sedimentary strata were deposited in marine or nonmarine environments. A critical parameter for proxy reliability is the residence time of aqueous species in seawater, which is rarely considered for proxies relying on stable isotopes and elemental abundance ratios. Differences in residence time may affect our ability to track geologically short-lived alternations between marine and nonmarine conditions. To test this effect for sulfur and nitrogen isotopes and sulfur/carbon ratios, we investigated a stratigraphic section in the Miocene Oberpullendorf Basin in Austria. Here, previous work revealed typical seawater-like rare earth element and yttrium (REY) systematics transitioning to nonmarine-like systematics. This shift was interpreted as a brief transition from an open marine depositional setting to a restricted embayment with a reduced level of exchange with the open ocean and possibly freshwater influence. Our isotopic results show no discernible response in carbonate-associated sulfate sulfur isotopes and carbon/sulfur abundance ratios during the interval of marine restriction inferred from the REY data, but nitrogen isotopes show a decrease by several permil. This observation is consistent with the much longer residence time of sulfate in seawater compared with REY and nitrate. Hence, this case study illustrates that the residence time is a key factor for the utility of seawater proxies. In some cases, it may make geochemical parameters more sensitive to marine water influx than paleontological observations, as in the Oberpullendorf Basin. Particular care is warranted in deep time, when marine residence times likely differ markedly from the modern.

description: We have devised a technique for measuring some of the most important nuclear reactions in stars which we expect to provide considerable improvement over previous experiments. Adapting ideas from dark matter search experiments with bubble chambers, we have found that a superheated liquid is sensitive to recoils produced from γ-rays photodisintegrating the nuclei of the liquid. The main advantage of the new target-detector system is a gain in yield of six orders of magnitude over conventional gas targets due to the higher mass density of liquids. Also, the detector is practically insensitive to the γ-ray beam itself, thus allowing it to detect only the products of the nuclear reaction of interest. The first set of tests of a superheated target with a narrow bandwidth γ-ray beam was completed and the results demonstrate the feasibility of the scheme. The new data are successfully described by an R-matrix model using published resonance parameters. With the increase in luminosity of the next generation γ-ray beam facilities, the measurement of thermonuclear rates in the stellar Gamow window would become possible.

To the contrary, interface law for the effective stress has been a subject of controversy. Recently, a pressure jump interface law has been rigorously derived by Marciniak-Czochra and Mikelić. In this paper, we provide a confirmation of the analytical result using direct numerical simulation of the flow at the microscopic level.

description: Susceptibility to the commercially important fruit disorder ‘neck shrivel’ differs among European plum cultivars. Radial cuticular microcracking occurs in the neck regions of susceptible cultivars, but not in non-susceptible ones, so would seem to be causal. However, the reason for the microcracking is unknown. The objective was to identify potential relationships between fruit growth pattern and microcracking incidence in the neck (proximal) and stylar (distal) ends of selected shrivel-susceptible and non-susceptible cultivars. Growth analysis revealed two allometric categories: The first category, the ‘narrow-neck’ cultivars, showed hypoallometric growth in the neck region (i.e., slower growth than in the region of maximum diameter) during early development (stages I + II). Later (during stage III) the neck region was ‘filled out’ by hyperallometric growth (i.e., faster than in the region of maximum diameter). The second category, the ‘broad-neck’ cultivars, had more symmetrical, allometric growth (all regions grew equally fast) throughout development. The narrow-neck cultivars exhibited extensive radial cuticular microcracking in the neck region, but little microcracking in the stylar region. In contrast, the broad-neck cultivars exhibited little microcracking overall, with no difference between the neck and stylar regions. Across all cultivars, a positive relationship was obtained for the level of microcracking in the neck region and the difference in allometric growth ratios between stage III and stages I + II. There were no similar relationships for the stylar region. The results demonstrate that accelerated stage III neck growth in the narrow-neck plum cultivars is associated with more microcracking and thus with more shrivel.

description: This article examines the complexity of young children’s engagement with fairy tales through the art of storytelling. The focus is specifically on how children co-construct the narrative in and after a storytelling event through means provided by the fairy tale and the storyteller’s performance. The study is based on fieldwork with first-grade students aged 6–7 years old in a Norwegian school. The study shows how children seemed to continue constructing meaning after the storytelling event. In this construction process, they revealed individual experiences of the shared event, as well as elements of the story. Some children’s memories of the story seem closely related to their engagement in the storytelling event—whether verbal or nonverbal. Our findings support the relationship between narrative and thinking and the importance of engaging with stories and storytelling to learn this way of thinking, and thus, the importance of storytelling in the school curriculum.
Promoting metacognition in extensive and academic reading for EAP students: a mixed-methods study
Creators: name: Brigg, Paul
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This study examines the role of extensive reading (ER) in promoting metacognitive thinking in academic reading (AR) during a 15-week ER-AR Course. Narrative reading in ER is a sense-making activity and this research aims to have this cognitive ability play a role in academic reading and writing. There were 72 experimental participants in four classes beginning an English for Academic Purposes (EAP) program. Critical-thinking strategies were first developed in ER shared-reading lessons through focussing on six targeted metacomprehension strategies known to be used by effective readers. The same strategies were then available in subsequent AR lesson activities. Analogous problem solving involving the strategies was found to transfer or operate in parallel between the two reading sources. Three quantitative tests based on the declarative, conditional and procedural stages of knowledge-development theories provided statistical data which were then corroborated from qualitative sources in a mixed-methods approach. These data were derived from written-response lesson activities, monitored sustained-silent-reading (SSR) reports and spoken responses in think-aloud interviews and a teachers’ focus group. Students were required to complete approximately 35 hours of SSR as well as attend the 90-minute lessons. The results showed second language (L2) learners to be adept critical thinkers. The quantitative results showed significant improvements in metacomprehension knowledge from pre- and post-testing of the experimental participants, and from comparison testing with equivalent control groups not undertaking the ER-AR course. Rich, descriptive details provided examples of transfer or parallel use of the metacomprehension strategies in ER and AR. In individual, class and cohort assessments, a significant majority of participants demonstrated planful and evaluative critical thinking in academic reading and writing. The study implication is that blending ER and AR can provide an effective and enjoyable introduction to the metacognitive thinking necessary in academic disciplines.

description: We characterize the Millimeter Astronomy Legacy Team 90 GHz (MALT90) Survey and the Mopra telescope at 90 GHz. We combine repeated position-switched observations of the source G300.968+01.145 with a map of the same source in order to estimate the pointing reliability of the position-switched observations and, by extension, the MALT90 survey; we estimate our pointing uncertainty to be 8 arcseconds. We model the two strongest sources of systematic gain variability as functions of elevation and time-of-day and quantify the remaining absolute flux uncertainty. Corrections based on these two variables reduce the scatter in repeated observations from 12-25% down to 10-17%. We find no evidence for intrinsic source variability in G300.968+01.145. For certain applications, the corrections described herein will be integral for improving the absolute flux calibration of MALT90 maps and other observations using the Mopra telescope at 90 GHz.

The random field Ising model with an asymmetric trimodal probability distribution

Year: 2013
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The Ising model in the presence of a random field is investigated within the mean field approximation based on Landau expansion. The random field is drawn from the trimodal probability distribution $P(h_{i})=p δ(h_{i}-h_{0}) + q δ(h_{i}+h_{0}) + r δ(h_{i})$, where the probabilities $p, q, r$ take on values within the interval $[0,1]$ consistent with the constraint $p+q+r=1$ (asymmetric distribution), $h_{i}$ is the random field variable and $h_{0}$ the respective strength. This probability distribution is an extension of the bimodal one allowing for the existence in the lattice of non magnetic particles or vacant sites. The current random field Ising system displays second order phase transitions, which, for some values of $p, q$ and $h_{0}$, are followed by first order phase transitions, thus confirming the existence of a tricritical point and in some cases two tricritical points. Also, reentrance can be seen for appropriate ranges of the aforementioned variables. Using the variational principle, we determine the equilibrium equation for magnetization, solve it for both transitions and at the tricritical point in order to determine the magnetization profile with respect to $h_{0}$.

Exhaustive Property Oriented Model-based Testing With Symbolic Finite State Machines (Technical Report)
Creators: name: Krafczyk, Niklas

Publisher: name: Zenodo
Year: 2021

description: This technical report is an extended version of a paper with the same title, submitted by the authors to the SEFM 2021 conference https://sefm-conference.github.io.
 In this paper, new contributions to property oriented testing (POT) against
 SFSM models are presented. While several POT approaches are known,
 none of these is exhaustive in the sense that every implementation
 violating the property is uncovered by a given test suite under certain hypotheses. On the other hand,
 numerous exhaustive theories for testing against models specified in various formalisms exist, but only for
 conformance testing. Since a hybrid approach using both models and properties seems to be preferred in industry, this paper presents an approach to close this gap.
 For given properties that are at the same time represented in a reference model,
 a test suite derivation procedure is presented, and its
 exhaustiveness is proven. The technical report extends the paper by full proofs for the lemmas and theorems stated there, and it discusses examples regarding the test case reduction achievable when testing for specific properties instead of checking full model conformance.

description: Confined scalar fields, either by a mass term or by a mirror-like boundary condition, have unstable modes in the background of a Kerr black hole. Assuming a time dependence as $e^{-iωt}$, the growth time-scale of these unstable modes is set by the inverse of the (positive) imaginary part of the frequency, Im$(ω)$, which reaches a maximum value of the order of Im$(ω)M\sim 10^{-5}$, attained for a mirror-like boundary condition, where $M$ is the black hole mass. In this paper we study the minimally coupled Klein-Gordon equation for a charged scalar field in the background of a Reissner-Nordström black hole and show that the unstable modes, due to a mirror-like boundary condition, can grow several orders of magnitude faster than in the rotating case: we have obtained modes with up to Im$(ω)M\sim 0.07$. We provide an understanding, based on an analytic approximation, to why the instability in the charged case has a smaller timescale than in the rotating case. This faster growth, together with the spherical symmetry, makes the charged case a promising model for studies of the fully non-linear development of superradiant instabilities.

'Really respectable settlers' : Peninsular War veterans in the Australian colonies, 1820s and 1830s
Creators: name: Wright, Christine A.
Publisher: name: Canberra, ACT : The Australian National University
Year: 2005

description: As the Napoleonic Wars convulsed Europe during the early nineteenth century, many more British young men than ever before became army officers, particularly during the latter part of the conflict, fought in Spain and Portugal between 1808 and 1814. The Peninsular War provided not only employment, but also the opportunity to climb the social ladder. As this thesis will demonstrate, the majority of British army commissions in this period were not purchased, and it was these men who later came to settle in the Australian colonies. After the demobilization of the British army following the battle of Waterloo in 1815, many officers found themselves on half-pay, doing the rounds of government offices seeking colonial positions; some were successful and were appointed to New South Wales. As well, many of those who came to New South Wales in garrison regiments, from 1817 onwards, found the place appealing and decided to settle. These British army officers, and those others who came in the next couple of decades, were a unique group of emigrants because of the skills they brought with them acquired in the army: self-discipline, self-reliance, the knowledge of how to discipline men, reconnaissance and exploring techniques, mapping, survey, engineering, town planning, medical skills and the building of roads and bridges. They were also Protestant, educated, literate and artistic men, and the carriers of British colonizing notions. They arrived at an opportune time to fill key positions in the newly created civil services in New South Wales and Van Diemen's Land. They also took advantage of British government regulations and obtained land grants under favourable conditions, something hitherto unattainable for them in Britain. In any case, it was mutually beneficial for the British Government and the Australian colonies to plant ex-army officers in what was the colony farthest away from Britain. Also revealed are the social networks created by Peninsular War veterans on the other side of the world, and their influence in the Australian colonies. These networks made an impact on the exercise of the law, marriage and settlement patterns, and the social and public life of the colonies. Many of the men who in earlier histories have been called 'the founding fathers' of Australia had a Peninsular War background and developed related social networks. John Macarthur proposed to Commissioner Bigge in1821 that the colony of New South Wales needed 'really respectable settlers'. Peninsular War veterans proved to be ideal in this respect, and in many others besides. The role of these veterans demonstrates key aspects of the emergence of the 'second' British Empire in the early nineteenth century, and also the change in the nature of the colony of New South Wales, from a penal and military society to a free one.

Re-thinking Extrinsic Materials in Statutory Interpretation: Revelations from the Legislative Process
Creators: name: Dharmananda, Jacinta
Publisher: name: The Australian National University
Year: 2023

description: The well-established framework of text, context and purpose in statutory interpretation emphasises a statute as a 'speech act' authored by Parliament and so to be construed in terms of conventions about language. But this framework does not sit well with the ability of courts and other interpreters to refer to extrinsic materials. It has led to a state of the law where recourse to such materials is poorly rationalised, sometimes contradictory and offers little cohesive guidance for an assessment of the probative value of extrinsic materials in an interpretative task. In an attempt to better understand the use of extrinsic materials, this thesis adopts a different perspective. It uses an institutional approach to the use of extrinsic materials to explore whether that approach offers a clearer rationale and a more systematic framework for the use of these materials in interpretation. This approach is not about institutional power, but about the processes and participants involved in the making of statutes and extrinsic materials. The High Court has made broad comments about the institutional setting of statutes. These comments and the very nature of extrinsic materials (products of, or relevant to, the making of a statute) invite a rigorous institutional perspective. However, despite occasional extra-judicial comments about the merits of exploring institutional factors, and a growing body of American scholarship in support of this perspective for statutory interpretation, the institutional setting of statutes has not been extensively explored in Australian statutory interpretation scholarship, and not at all for extrinsic materials. To adopt this approach, this thesis asks what can we learn from the legislative process about the use of extrinsic materials in statutory interpretation. It uses a variety of methodologies. It starts with a historical analysis to identify the recent origins of the current law. Then it engages in a doctrinal analysis to establish the current state of the law. The thesis then undertakes a quantitative empirical analysis of High Court of Australia and Full Court of the Federal Court of Australia cases to provide evidence of patterns of use of extrinsic materials. The thesis then engages in exploratory research by examining the processes, actors, and materials involved in the making of a statute, from executive approval of a legislative proposal through to parliamentary enactment. Learnings from the exploratory research are then used as a basis for an analysis. That analysis suggests a tension in the law relating to extrinsic materials, and that an institutional perspective offers an alternative rationale for why courts refer to extrinsic materials as well as suggested guidance about their appropriate use.

Those data also include echoes attributed to stratified impurities or dielectric discontinuities within the ice sheet (“lay-ers"), which allow studies of a) estimation of the relative contribution of coherent (discrete layers, e.g.) vs. incoherent (bulk volumetric, e.g.) scattering, b) the magnitude of internal layer reflection coefficients, c) limits on the azimuthal asymmetry of reflections (‘birefringence’), and d) limits on signal dispersion in-ice over a bandwidth of ∼100 MHz. We find that i) after averaging 10000 echo triggers, reflected signal observable over the thermal floor (to depths of approximately 1500 m) are consistent with being entirely coherent, ii) internal layer reflection coefficients are measured at approximately –60 to –70 dB, iii) birefringent effects for vertically propagating signals are smaller by an order of magnitude relative to comparable studies per- formed at South Pole, and iv) within our experimental limits, glacial ice is non-dispersive over the frequency band relevant for neutrino detection experiments.

description: We demonstrate a large light absorptance (80%) in a nanometric layer of quantum dots in rods (QRs) with a thickness of 23 nm. This behavior is explained in terms of the coherent absorption by interference of the light incident at a certain angle onto the very thin QR layer. We exploit this coherent light absorption to enhance the photoluminescent emission from the QRs. Up to a seven- and fivefold enhancement of the photoluminescence is observed for p- and s-polarized incident light, respectively.

Guardians of Memory: The Indonesian military's collective memory of East Timor
Creators: name: Sambhi, Natalie
Publisher: name: The Australian National University
Year: 2023

description: For the Indonesian military, the independence of East Timor in 1999 represented the end of twenty-three years of seemingly futile efforts to integrate the province into the Republic of Indonesia. This thesis asks: what is the Indonesian military's collective memory of its experience in East Timor? Does the Indonesian military, long seen as the custodian of national sovereignty and a bulwark against communism, see that campaign as a failure or loss, and, if so, what impact has this had on its sense of identity? Drawing on manifestations of the Indonesian military's official memory as found in public museums and monuments as well personal memoirs, this thesis finds that the military's public narrative of East Timor rejects defeat, reworking the memory of that campaign to affirm its identity and public image as omnipotent "Guardians of the Nation". However, private memories, as articulated in interviews with 26 active and retired members, reveal that within the military, the memories of East Timor are more ambivalent, ranging from an acceptance of failure to outright denial of responsibility. This research seeks not only to contribute to a deeper understanding of the Indonesian military and its place in Indonesian political culture but also contribute to the broader scholarship on how militaries rationalise 'difficult histories' such as defeat and failure.
IT governance: a study of implementation, evolution and critical success factors

description: IT has become critical to organisations for the support, sustainability and growth of the organisation, and improving IT governance is an increasingly crucial area for organisations to foster and improve. However, current IT governance models, based on a mixture of structures, processes and relational mechanisms, have failed to include both IT governance evolution and critical success factors, which are recognised as key elements for effective IT governance. In addition, there is little research in this important area. This study aims to address the gaps in the research and to develop an extended model of governance. This exploratory study follows a qualitative theory-building research approach in developing a more comprehensive model of IT governance than currently exists. The study conducted case studies in six selected Hong Kong public organisations in four industries to acquire data. Analysis of interviews with 20 participants including CEOs, senior executives, heads of business, heads of IT and IT managers was used to determine the essential IT governance mechanisms for effective IT governance implementation. A new model emerged from the results, which contained five key domains: structures, processes, relational, success and evolution. The first three domains contained mechanisms to directly enact IT governance processes, the success domain contained critical success factors to enable achievement of effective IT governance and the evolution domain contained mechanisms to ensure positive IT governance evolution. The major contribution of this study is this newly developed holistic and integrated model which provides a comprehensive, integrated and total view on the essential IT governance mechanisms necessary for effective IT governance implementation. This contribution is important due to the lack of comprehensive and integrated models in the literature, and the model can be used as a reference for organisations to improve their IT governance. The IT governance mechanisms identified in this study provide the foundation for further research into the area and insights into means for improving IT governance.
Magnetic domain growth in a ferromagnetic Bose-Einstein condensate: Effects of current

description: Magnetic domain patterns in a ferromagnetic Bose-Einstein condensate (BEC) show different properties depending on the quadratic Zeeman effect and dissipation. Another important factor that affects domain patterns and domain growth is superfluid flow of atoms. Domain growth in a ferromagnetic BEC with negative quadratic Zeeman energy is characterized by the same growth law as (classical) binary fluid in the inertial hydrodynamic regime. In the absence of the superfluid flow, the domain growth law for negative quadratic Zeeman energy is the same as that of scalar conserved fields such as binary alloys.

Phase Transition and Strong Predictability

description: The statistical mechanical interpretation of algorithmic information theory (AIT, for short) was introduced and developed in our former work [K. Tadaki, Local Proceedings of CiE 2008, pp.425-434, 2008], where we introduced the notion of thermodynamic quantities into AIT. These quantities are real functions of temperature T>0. The values of all the thermodynamic quantities diverge when T exceeds 1. This phenomenon corresponds to phase transition in statistical mechanics. In this paper we introduce the notion of strong predictability for an infinite binary sequence and then apply it to the partition function Z(T), which is one of the thermodynamic quantities in AIT. We then reveal a new computational aspect of the phase transition in AIT by showing the critical difference of the behavior of Z(T) between T=1 and T<1 in terms of the strong predictability for the base-two expansion of Z(T).

description: DNA, RNA and proteins are among the most important macromolecules in a living cell. These molecules are polymerized by molecular machines. These natural nano-machines polymerize such macromolecules, adding one monomer at a time, using another linear polymer as the corresponding template. The machine utilizes input chemical energy to move along the template which also serves as a track for the movements of the machine. In the Alan Turing year 2012, it is worth pointing out that these machines are "tape-copying Turing machines". We review the operational mechanisms of the polymerizer machines and their collective behavior from the perspective of statistical physics, emphasizing their common features in spite of the crucial differences in their biological functions. We also draw attention of the physics community to another class of modular machines that carry out a different type of template-directed polymerization. We hope this review will inspire new kinetic models for these modular machines.

description: In this paper, we study the trapping problem in two representative polymer networks, Cayley trees and Vicsek fractals, which separately model dendrimers and regular hyperbranched polymers. Our goal is to explore the impact of trap location on the efficiency of trapping in these two important polymer systems, with the efficiency being measured by the average trapping time (ATT) that is the average of source-to-trap mean first-passage time over every staring point in the whole networks. For Cayley trees, we derive an exact analytic formula for the ATT to an arbitrary trap node, based on which we further obtain the explicit expression of ATT for the case that the trap is uniformly distributed. For Vicsek fractals, we provide the closed-form solution for ATT to a peripheral node farthest from the central node, as well as the numerical solutions for the case when the trap is placed on other nodes. Moreover, we derive the exact formula for the ATT corresponding to the trapping problem when the trap has an uniform distribution over all nodes. Our results show that the influence of trap location on the trapping efficiency is completely different for the two polymer networks. In Cayley trees, the leading scaling of ATT increases with the shortest distance between the trap and the central node, implying that trap's position has an essential impact on the trapping efficiency; while in Vicsek fractals, the effect of location of the trap is negligible, since the dominant behavior of ATT is identical, respective of the location where the trap is placed. We also present that for all cases of trapping problems being studied, the trapping process is more efficient in Cayley trees than in Vicsek fractals. We demonstrate that all differences related to trapping in the two polymer systems are rooted in their underlying topological structures.
